Ask HN: What have you created that deserves a second chance on HN?

268 points by paulgb 4y ago

We all know there’s a big luck component to breaking off the /new page. I want to see the original content that you’re proud of but flopped on HN.

https://app.dev-esc.com/new_game/ https://app.dev-esc.com/new_game/ - an online escape room for developer teams. I aimed to make a team-building experience that was a bit different. unashamedly geeky: you’ll need puzzling and some coding to solve the challenges. Fully remote for teams of 1-8ish; free to explore. Requires a computer, although you can explore on mobile/tablet. Originally it was free to play - I got a fair few plays off my HN post, now I have a trickle of paying customers.

  Oh I played this! I bought it to play with a friend over Discord and we had a real fun time, it was sort of the perfect niche (for us) Personally I wish there were more of these. Having the one was nice but it's hard to play with another person when you already know the solution. And it's just fun to play more puzzles with the same friend. Thanks for making it :3!
  - csarva 4y ago
    Looks like there’s a new puzzle now, give it another look!
  - mozz100 4y ago
    Thank you for this, you made my day. I have recently made a new room for /dev/esc - my idea was that in the run-up to Christmas, plenty of dev teams would be looking for activities to do together. Full disclosure: it didn't work - I didn't get a bump of new customers. If you can look past the festive theming, IMHO there are some good, totally original new puzzles in "Santa's Tech Disaster". (choose from drop-down when setting up a new game)
    - cobertos 4y ago
      Tbh, Christmas was a heads down, stressful time for me. I'm wondering if the opposite might actually be true of dev teams around Christmas? But thanks! I'll have to get my friend to play again. Looking forward to it

https://confluo.app https://confluo.app - A productivity assistant app that instead of planning your day in advance dynamically suggests you tasks to pick based on the time of the day. Planning ahead never worked for me as something unexpected always came along. Hence I wanted an app that I can open, go through a list of task suggestions and pick the one I like. In addition, I included features like timer, pomodoro, and virtual co-working that helped me stay productive during the lockdowns. I also wanted to track how many hours I was working and which skill I was spending my time on, so I also those features. I shared it on HN, hoping people will like it. But it never made it to new page :(

https://lite.markee.io/?utm_source=startups.fyi https://lite.markee.io/?utm_source=startups.fyi I've been learning video streaming tech for the last year (ffmpeg, webrtc, all the great videos available of SF Video Technology - https://www.youtube.com/@SFVideoTechnology https://www.youtube.com/@SFVideoTechnology) and I haven't been able to come up with a remotely interesting product idea. When I came across this, I thought it was the most clever SaaS video tech I've seen in a while. I'm probably dating myself but I'm certain TokBox had something similar 10 years ago. In whichever flavor markee is doing this, it was a refreshing idea to see. I have no affiliation to this product or engineering team.

https://scipipe.org https://scipipe.org - A pipeline tool for shell commands by a declarative flow-based API in Go Github link: https://github.com/scipipe/scipipe https://github.com/scipipe/scipipe There are many pipeline tools for shell commands, but a majority has one or more limitations in their API which makes certain complex pipelines impossible or really hard to write. We were pushing the limits of all the tools we tried, so developed our own, and implemented it in Go, with a declarative API for defining the data flow dependencies, instead of inventing yet another DSL. This has allowed us great flexibility in developing also complex pipelines, e.g. combining parameter sweeps nested with cross-validation implemented as workflow constructs. SciPipe is also unique in providing an audit report for every single output of the workflow, in a structured JSON format. A helper tool allows converting these reports to either an HTML report, a PDF, or a Bash script that will generate the one accompanying output file from scratch. An extra cool things is that, because the audit reports live alongside output files, if you run a scipipe workflow that uses files generated by another scipipe workflow, it will pick up also all the history for the input files generated by this earlier workflow, meaning that you get a 100% complete audit report, even if your analysis spans multiple workflows! (More on the audit/provenance report in this post: https://rillabs.com/posts/provenance-reports-in-scientific-workflows https://rillabs.com/posts/provenance-reports-in-scientific-w... )
- greazy 4y ago
  Very interesting. This is like snakemake but with go. The audit trail is very interesting, especially for certified version controlled pipelines. Is it being continually developed?
  - samuell 4y ago
    Thanks for kind words! Yes, although conceptually it is even more similar to Nextflow. That is, it is push-based and dataflow-based, whereas Snakemake is pull-based, quite similar to Luigi (well, hey, we also developed the SciLuigi plugin to make Luigi a tad bit more data flow-like, although only on the surface). I'm maintaining and continuing to develop SciPipe, although pretty slowly at the moment, due to a day job that doesn't allow much time to spend on it. I and a former colleague at pharmb.io who is still using it are having some plans for further features to streamline the authoring experience more though, and I'm actually looking to move to a job (e.g. in academia) that will allow me to work on it a bit more on the side.

https://mmabetsharp.com https://mmabetsharp.com A website to help make informed bets on the UFC. It presents a lot of relevant data if you're serious about MMA sports betting. I made this during the pandemic and tried to promote it through Reddit and Twitter, but it mostly fell flat and ran out of steam. I only scratched the surface of what I intended here. The data on the site is a bit outdated since neither I nor anyone has used it in a while. A bit bummed that it never caught on within the MMA capping community, but I've felt I could always come back to it if the potential expressed itself.
- hnrodey 4y ago
  This is rad. I'd love to see it updated with current data. I've tried to bet on MMA with mixed results, but ultimately tried to find a data driven approach to place wagers. My approach would net me tons of open browser tabs trying to track down stats about each fighter :( I really like what you've done.
  - sinker 4y ago
    Thanks I really appreciate that. MMA (UFC specifically) is still wide open to advantage betting because lines are often highly narrative-based. Data itself WRT to MMA is often misleading though for so many reasons (e.g., low quality of opponents presenting a skewed perception of fighter ability). However, looking at specific things is often quite useful. The submission charts section of the site was particularly useful to me. You find that some fighters are skilled at one specific submission and that sometimes their opponents are highly vulnerable to that particular submission. A big issue I found when trying to market the site was that, the majority of bettors have no interest in looking at data, reviewing fights, or putting any time towards making informed bets. Most people prefer to place bets naively primarily for the sake of entertainment.
    - jjxw 4y ago
      I think an interesting observation here is that the very thing that makes it difficult to get adoption of this product/data is the thing that makes the product/data valuable. Without the naive/narrative/entertainment bettors it would be more difficult to find an edge. Presumably there is a very small, niche population that would find this information very valuable. Funnily enough, those that do find it valuable are unlikely to share it - if they're acting in their own self interest they don't want other sophisticated bettors to enter the market and inadvertently help the bookies set the line more accurately.

https://www.twitch.tv/watchmeforever https://www.twitch.tv/watchmeforever - AI-generated (aside from the artwork) parody of '90s sitcoms, running forever (24/7/365). We worked on this w/ a very small team for the past four years, in-between our day jobs. When started, OpenAI didn't have an API, and Stable Diffusion definitely wasn't a thing, so we had to come up with novel methods to thread cohesive content together. Most of the "creative" details e.g., laugh track, dialogue, frequency of dialogue, camera shots, and so on, are all tunable on a per scene basis. We're in sort of a holding pattern right now -- no clear path to monetization for the project, and it hasn't garnered enough attention for us to probably get funding based on the technology backbone. Hope you enjoy it! Labor of love. :)

Maybe I'll just make a plan now for a standing desk and a boring old stool and try to implement the same idea into my current workflow

https://sequencer.party https://sequencer.party It is a modular audio/video/midi environment that supports Google Docs-like multiplayer, and supports third-party plugins (a format called Web Audio Modules 2 -- like VST or AU but for the web).

Still a lot to do on it, but in it's current format I've had some fun jam sessions where people sequence my hardware synthesizers over MIDI, and listen to the result over twitch. Longer-term it will have thousands of samples, many more WAM plugins built in and templates available in the public library, integration into freesound and archive.org I've previously made two synth-related apps for iOS (Synth Modes and Spectrum synthesizer bundle).

Nothing flopped, it just never reached breakout success the way I wanted. Most things I managed to get into the top 5 of the front page of HN over the span of 8 years, whether it was a project, blog posts or products but that's just a moment in time, a few hours even, it's not success. I wish my projects had reached the point that I could have carried on working on them. The latest M3O.com, was a serverless API gateway, that honestly I thought as a product was great but never achieved the thing I set out for it to be. It was also VC funded, so even more painful that it didn't work out. Now I'm hacking on something new, not shared it yet but let's do it. Mu is an operating system for Life. We're addicted to the internet, we're being used by tech companies for profit, we're stuck scrolling and clicking. I want to strip it all away and redefine what an operating system is for.

It adds opt-in reactivity, so that pressing ctrl+shift+enter triggers execution of all cells that depend (recursively) on the current cell. Furthermore, with its `code` function, you can see exactly what code is needed to reproduce a given variable. I started working on it after watching the famous talk "I Don't Like Notebooks" by Joel Grus, and, anecdotally, I like notebooks just a little more when I use this kernel :)

https://codeatlas.dev https://codeatlas.dev - codebase visualisation tool It takes your git repo and generates a beautiful visual representation of the actual code that's in it.

You can run codeatlas as part of your CI with our Github Action (https://github.com/codeatlasHQ/codebase-visualizer-action https://github.com/codeatlasHQ/codebase-visualizer-action). We made this because grokking complex software projects is really difficult and we've found that a visual overview of what's in a codebase can be quite helpful to get started. E.g. checkout https://codeatlas.dev/gallery/kubernetes/kubernetes https://codeatlas.dev/gallery/kubernetes/kubernetes for the generated visualisation of the Kubernetes Github repo! We slowed down active development after our initial attempts at dissemination didn't really go anywhere (bragging about side projects on the internet, ugh), but would still love feedback on whether this is possibly useful to anyone else!

https://moonjump.app https://moonjump.app Moonjump is a server that redirects you to a random page harvested from Are.na, Hacker News, Marginalia Search, and Gossip Web. This project aims to spark curiosity and provide a portal to the vast collection of interesting material hidden by the commercial web. The source material is aggregated with care by users of these platforms. Since this accumulation is performed by hand, pages are saved because they had an effect on the users who saved them. The goal is to find something that has an effect on you. For Are.na, the dictionary of channels that the app pulls from is weighted by the number of pages in the channel. Channels with the most pages are more likely to be selected. Moonjump makes a decision for you by selecting something random from a deep sea of unconventional content. Results may be peculiar, profound, or absolute nonsense. But you can always close the tab and jump again. The search engine is powered by Marginalia. I have to admit that the existence of Marginalia is a huge inspiration for Moonjump. Search queries on Moonjump use the Marginalia API to redirect you to a random result. The easiest way to jump is to click the large logo at the center of the homepage. You can also add https://moonjump.app/jump https://moonjump.app/jump to your bookmarks bar. If you are an OSX user and have hammerspoon installed, check the github repo for instructions on how to jump via a keyboard shortcut. github: https://github.com/ya1sec/moonjump https://github.com/ya1sec/moonjump

https://store.steampowered.com/app/656280/Fractus/ https://store.steampowered.com/app/656280/Fractus/ Simple arcade-style game. I ran out of steam developing this. The gameplay and UI need work, but I thought the graphics were interesting. All the units are rendered as Mandelbrot and Julia sets on the GPU. Parameters are varied in real time to make the fractals look like they are moving and swimming. Another fun thing is the audio effects were made with an electric guitar. Thanks for reading :D

  You might get some more eyes on your game if you released it on Itch. It seems to me that it would fit better with the gamejam scene than general consumption. With my amateur game design hat on (discard if you please): I think that the game could be much improved with a drum track to make playing the game feel more zen. I get the vibe that it isn't a game that you "play" but more of a time killer. It would be extra cool if the audio effects could play in time with the drum track, too. The player could be composing a song as they play.

https://www.newsy.co https://www.newsy.co My modern day take on domain parking. I used to have ~50 domains just sitting there doing nothing. Got sick of it. Didn't want to do ugly domain parking pages, but also didn't have time to develop them. I wanted something useful and something that still offered value. Newsy creates an automated content aggregator (think of Reddit but automated) for your domain based on the keywords you describe. Over the years, a lot of features went in including newsletter, membership etc. The best option for the users was providing ways to monetize - including bringing your own ads, charging for posts, paid membership etc.

  Disclaimer: I am friends with the author of log-store and have been occasionally helping test the software. I've been using log-store at work for some time. It has an awesome 'admin' UX. The sysadmin/ops overhead associated with getting something useful out of log aggregation and analysis is so much lower than tools like splunk and elasticsearch. If you're interested in getting some kind of log analysis/aggregation spun up quickly and don't need all the complexity associated with things like ES and splunk, definitely give it a test drive.

The thing below - one of the links at the bottom goes to its "Show HN" page, where people can check that only received 4 points. Many people discuss REPL tricks here, so I didn't expect it to flop so miserably... Show HN: Eev and TikZ, or: how to learn TikZ using a REPL (twu.net) Hi all, I made a video that at first sight is about a way to use REPLs to explore TikZ - and TikZ is a huge (La)TeX package for drawing graphics... At second sight that video is about a series of tricks for using REPLs in Emacs, and TikZ is just an excuse to present them. As far as I know those tricks are very unusual; they implement a kind of "meta-REPL" that controls other REPLs, and they do that in a way that is much simpler, and much easier to hack, than Org's code blocks and than the cells in Jupyter notebooks. The page has lots of screenshots and links, and it has instructions for downloading the video and its subtitles, and for reading the subtitles in plain text. I tried to make everything as accessible as possible for the people who just want to watch the the first two parts of the video - "Introduction" and "Trying it" - in super-high speed. I'm especially interested in pointers to related work.

My target was under 1 second. After the board is built where all the numbers are random, then the code removes numbers also randomly in order to play the game. That randomness turned out to be a nice little challenge :-) It seems to work okay for the most part. Myself and other family members play it often now.. which is really cool. There are no scores. If you guess wrong there is no penalty. Just low key, low stress game.

The only FOSS thing I've done that I think is really worth telling people about is KaithemAutomation, a home automation server in pure Python with a bit easier setup than Home Assistant, and some features aimed at commercial installs like room escape control, and some pretty decent network video recorder features. https://github.com/EternityForest/KaithemAutomation https://github.com/EternityForest/KaithemAutomation I put 6 years or so into it, and have used it on plenty of contract projects, but so far I don't think anyone else is interested. Possibly because it's largely UI and CRUD over existing functionality, and there's not much particularly exciting to the hacker community, few interesting algorithms, it's not minimalist at all, etc. Plus it has a lot of dependencies that might or might not exist outside of Debian, I've never looked into how it would run on the more DIY distros since I've never used them.

ts-liveview: https://github.com/beenotung/ts-liveview https://github.com/beenotung/ts-liveview A lightweight implementation of the “fullstack liveview” in Typescript. You can do initial contentful rendering and realtime DOM updates from the server over http and websocket with only 6.5K of js minified (22x smaller than react, 2.6x smaller than svelte). It was inspired from the Phoenix Liveview but evolved to adopt TSX with explicit DOM updates with querySelectors (without vdom diff-ing). Unlike most js frameworks, it is a starter template, not a package. So you’re free to modify and extend / trim it to better fit your need.

- TrickardRixx 4y ago
  I see in the repo you mention wanting to add support for archiving. I'd really like to see a sort of master playlist for a genre. Just keep adding the songs from each weekly playlist to the master genre playlist, then the "date added" field could be used for looking at the playlist historically. You lose duplicates this way, so maybe not the best archival strategy, but with the master playlist you could have hours of music instead of an hour.

Perhaps work on a CMake / Autoconf config for a library build? - The repository itself might not have enough visibility due to being self hosted.

    > Graphs of benchmark results would be neat to have. Remember to put the code and graphs as a sort of TL;DR Thanks for the suggestion. I’ll use it when I get around to updating this page. For now though I’ll let it sit there, as I’m too tired with it at this point. > there's no clear instructions as to how I'd use it for my own projects. Perhaps work on a CMake / Autoconf config for a library build? It’s not meant to be used as a library. It’s only for demonstrative purposes. There are a couple choices made in this code motivated by that, like not checking for integer overflow, or hardcoding page size based on the target platform at compile time. If someone wants to use the code anyway, they should just copy it into their project and possibly modify the parts which aren’t up to snuff. That’s also what I’m doing, as I wrote a more robust version in Rust for my project. I only wrote C++ for the article, because that’s what more people are familiar with, and there are more implementations, so I got to benchmark this code against several implementations of std::vector. As for CMake/Autotools, I think the scripts in the repo are better for my little demo, as they don’t add any dependencies beyond what’s already available on each platform, they’re more transparent and easier to use. For a big project I’d probably use CMake, but I don’t think it’s warranted here. > The repository itself might not have enough visibility due to being self hosted. While I do love self-hosting, maybe posting a read-only mirror on GitHub would bring in more exposure? The intended path of discovery, when it comes to the repo, is through my article. It’s not meant to be independent, so I don’t really care about the discoverability of the repo as a stand-alone thing. As for GitHub, I don’t like it for a variety of reasons and if I can help it, I’ll avoid it.

I have a couple... 1. https://news.ycombinator.com/item?id=34507046 https://news.ycombinator.com/item?id=34507046 I made a port of Xixit to the X16 [video] It's super interesting as someone who never lived through the 80s watching someone programming an 8 bit system. Even more impressive is he is making his own "modern" 8 bit system with off the shelf parts! I'm amazed that people can make complex software in assembly. I feel like my brain can't deal with the limited abstraction For original content, I would shamelessly plug my post from a month ago titled "The Fascinating development of AI: From ChatGPT and DALL-E to Deepfakes Part 3" 2. https://www.deusinmachina.net/p/the-fascinating-development-of-ai-47b https://www.deusinmachina.net/p/the-fascinating-development-... I look at the 3 main technologies that are shaping the way we create content, in text, art, and video, and talk about how we got there. If I were writing it today I'd have to include a 4th part about VALL-E which came out right after I posted it. Maybe I'll write about that later. Excited to see what everyone else posts!

I created Scheme for Max and Scheme for Pure Data. They are extensions to the Max/MSP, Ableton Live, and Pure Data computer music environments that embed an s7 Scheme interpreter in the host so that you can script, automate, and live code the hosts with s7, a Scheme from the CCRMA computer music center at Stanford and the same one used in the Snd editor and the Common Music 3 algorithmic composition environment. This allows you to do things like write algorithmic music tools, sequencers, and use the Ableton Live API in Scheme, including with Common Lisp style macros. It has an API for integrating with Max to share data structures, hook into the scheduler, run in the high priority thread, and so on. (The Max javascript object does not run in the high thread and so while it is similar in scope, it can't be used for accurate timing, so is no good for sequencing or live algorithmic generation.) S4M allows you to do all the goodness of high level music programming in a Lisp, without losing the ability to use modern commercial tooling and instruments. It's my thesis project for a Masters in Music Technology with Andy Schloss and George Tzanetakis at the University of Victoria, and I plan to continue to a PhD working on it. I tried submitting twice, but it never made the page, which surprised me a bit given Lisp interest here.

I made (am making) an email inbox for your entire domain - https://pretzelbox.cc https://pretzelbox.cc. Great for solopreneurs and small teams who need use case specific emails like leads@domain or support@domain but don’t want to keep buying email inboxes. Here are a few cool things you can do with it - 1. Reply as anyone @your-domain 2. Comes with a built-in blog you can post to from your email much like world.hey.com 3. You can share emails as hyperlinks - great for sending reminders to people on WhatsApp/Messenger to tell them to take some action on an older email and to bookmark useful emails I have a few Chartered Accountant and small law firms practices using it but I thought it would take off in a much bigger way in the indie hacker community than it actually did.

A few years ago (~2017) I created a tool in the biomedical domain to design peptide vaccines. https://www.padiracinnovation.org/en/peptide_PoC/ https://www.padiracinnovation.org/en/peptide_PoC/ Peptide vaccines are not very efficient, but they can be easily designed to address a large number of diseases. Basically I would like that a pharmacist could use this tool with just 2 days training. How it works? If you know that a certain protein is produced by a certain type of malign cell and only by those cells, a peptide vaccine will cause the human immune system to try to eliminate the cells that produce that protein. The most obvious use is in the case of some cancers cells which produce a certain protein. These proteins are named "tumor specific antigen". It is an antigenic substance which is produced only by tumor cells. Tumor antigens are useful tumor markers in identifying tumor cells that are targeted by the immune system when it is primed by a peptide vaccine. Another interesting thing is that cancerous cells evolves quickly to try to evade therapies, here it's very easy to design a new peptide vaccine, for example every week. As the name hints at, it's a proof of concept, I designed several variations. A good thing is that you don't need a lot of CPU power to run it. I use a cheap VPS from OVH. I have written a large documentation here: https://www.padiracinnovation.org/en/peptide_PoC/doc/documentation_en.html https://www.padiracinnovation.org/en/peptide_PoC/doc/documen...

    Right, but that doesn't really answer my question. The stories appear harmless and so many are flagged it has to be automated. So presumably it's software driven. But - why? With political or contentious topics it's usually obvious why stories go dead but for /shownew it's not.

      The "killed by software" is my best guess. Probably more of a strict filtering algo and not as many users trying to reverse the process.

Lets you update a custom badge by API - fully open source. Lets you update the badges to say whatever you want as part of your CI process. For instance we have it show the number of build warnings the most recent build generated.

As a hobby project, I run Code::Stats[0]. It's a website that tracks what languages you are programming in (via editor plugins) and gives you a profile page with various statistics[1]. It's ad-supported (with EthicalAds) to deal with server costs, or you can buy a support account to remove ads. The site and all the editor plugins are open source, the site is written in Elixir (but I'm looking at integrating Gleam in the future). Currently it's completely a free time thing; I make negative money on it. My dream would be to have enough paying users to work on it part time (even a little), but that's far away and may never happen. But I like using it myself so I'll keep running it for the foreseeable future. [0] https://codestats.net/ https://codestats.net/ [1] https://codestats.net/users/Nicd https://codestats.net/users/Nicd

  Looks useful. I currently use untrackme, unalix, and link eye (the older version for which source is no longer available, not the new one). Feedback: I've submitted some comments on GitHub, but I'll go ahead and include some more here: - I'm not a fan of this UI; it seems both somewhat cluttered and small. I'm on tablet, fwiw. Consider a fullscreen UI with indicators for modules that can be activated by the current URL, rather than always showing all active modules. At the bottom of the screen, display either a grid or list of apps that can open this URL. This is better than hiding it away behind another tap. Perhaps have a toggle for whether the grid shows share to or open with? - consider a list of queries that will always be automatically removed from URLs, without interaction. For example, any time I share an Amazon URL, I remove everything after the asin; it would be easier if this was automatic. However these automatically removed queries should be listed in the history, so the original URL can still be obtained. - there's no option to remove hashes (#tag in the in-app example). Hashes are occasionally used with tracking as well, in combination with javascript. - Only show the modules if they're able to do something. For example, if no referrers are found, don't display the settings for that. Same for labels, queries, etc. - the pop-up goes away if I switch apps/open recents. Leaving it open would be nice. - allow sharing URLs to the app. Not all apps make it easy to directly open URLs in another app (Firefox custom tabs, for example; I use Lynket to open custom tabs, and long-pressing a link only lets me share or copy the URL)

https://grizzlybulls.com https://grizzlybulls.com It's a freemium subscription service to the algorithmic trading models / hedging systems I've been developing over the last few years. 2022 performance: SPX (benchmark): -18.77% Free models: TA - Mean Reversion Basic (https://grizzlybulls.com/models/ta-mr-basic https://grizzlybulls.com/models/ta-mr-basic): -9.93% TA - Trend Basic (https://grizzlybulls.com/models/ta-trend-basic https://grizzlybulls.com/models/ta-trend-basic): -17.79% Vix Basic (https://grizzlybulls.com/models/vix-basic https://grizzlybulls.com/models/vix-basic): -20.45% Premium models: Vix Advanced (https://grizzlybulls.com/models/vix-advanced https://grizzlybulls.com/models/vix-advanced): -17.9% Vix - TA Advanced (https://grizzlybulls.com/models/vix-ta-advanced https://grizzlybulls.com/models/vix-ta-advanced): -16.14% Vix - TA Macro Advanced (https://grizzlybulls.com/models/vix-ta-macro-advanced https://grizzlybulls.com/models/vix-ta-macro-advanced): -3.15% Vix - TA Macro Monetary Policy Extreme (https://grizzlybulls.com/models/vix-ta-macro-mp-extreme https://grizzlybulls.com/models/vix-ta-macro-mp-extreme): +0.56% The models use no leverage and are always either 100% long the S&P 500 or 0% long (in cash). These are not HFT, averaging one trade per 2-4 weeks on average depending on the model. You can see active signals for the free models by checking the site frequently, or if you subscribe to one of the premium plans you'll get email or text notifications as well. In 2022, all but one of the models beat the SPX on an absolute performance basis, some substantially so with the top model returning positive absolute returns with a +19.33% outperformance gap. However, it was still a much worse year than 2021 as the unprecedented reversal of Fed policy in response to 40 year high inflation proved to make a challenging backdrop.

https://crowdview.ai https://crowdview.ai - search engine for forums and discussion sites Like many of you, I find Google results to be full of SEO spam and have resorted to adding "site:reddit.com" or "site:news.ycombinator.com" to all my queries (since 2015!). Otherwise, it's really hard to figure out "what does a genuine, real life human think about this thing?". But limiting my results to just Reddit isn't ideal because so much great content exists elsewhere. Lots of great information and conversations have moved elsewhere, and niche forums are still alive on the web! But it's impossible to find these places because they rank so poorly on Google. So I built a search engine across a curated list of these, making sure to remove any kind of SEO junk (blog spam, listicles, etc). There's also a chrome extension that surfaces these results alongside Google, so you don't have to remember to keep coming back. Please try it out and share any feedback!

Splink - a FOSS python library for probabilistic record linkage (fuzzy matching/entity resolution). Splink is dramatically faster and works on much larger datasets than other open source libraries.

I’m an introvert – made an app to help maintain connections with people. Landing page is at https://communiqai.com https://communiqai.com and it's also on the Play Store at https://play.google.com/store/apps/details?id=dev.mtc.ga https://play.google.com/store/apps/details?id=dev.mtc.ga. CommuniqAI is an intelligent tool for scheduling and automating SMS text messages, calls and email. It’ll help you stay in touch with those who mean the most to you—and it’ll be there for you through life’s many distractions. Let’s face it, some of us are better at communicating than others. Rather than forgetting or being “too busy” to reach out to those who are important to you, CommuniqAI will cleverly send text messages of your choosing to, and smartly prompt you to call and email, the people you care about. Whether that person is a significant other, family member, friend, or even a patient, CommuniqAI will help you stay in constant contact. Some people are, very much, against automation technology like this, but I believe that anything that can help keep communication high between loved ones is, in the long run, a good thing. CommuniqAI, by default, will not take any action and largely act as a helpful reminder.

  Cool! Personally, I have set reminders to reach out to friends and family on my phone. I can therefore relate. The landing page communicates the honest intent behind this very well! If I were to use your product, I wouldn’t want to cycle through canned messages. Do you plan on making this truly AI-powered? That would be a game changer. Let your app draft both kind messages and responses, and allow the user to review and edit before sending. Then make it learn from those edits, and boom, you’ve built a personal social assistant. For now something more practical: as a typical user, I am not interested in my timezone. No need to show that specifically in such a large font.

  I don't know about everyone else, but to me programming with just the "subtract and branch if less than or equal to zero" instruction sounds way, way more frustrating than something like the TIS-100.

  Clever pivot! I was recently thinking it would be useful to track job posts that have been open for a long time. This could be a sign that the company is struggling to make a hire. As a freelance developer, that suggests they may be open to a cold call offer for a contract until they can fill the role. The hiring manager may be more receptive since the seat has been vacant for a while, and they can end the contract when the role is finally filled. Is that something you can build on top of your dataset?

    Thanks! Great question, and I should have been more clear in my terminology. We're more like a site builder + hosting provider than a general platform. The difference is between us hosting them directly i.e. Squarespace, and their presence on a platform where they are in a larger pool of creators and their branding is secondary i.e. Patreon/YouTube. The key is that even on our lowest tier there is no cross site discovery, the only presence of our branding is in the footer, and their membership list is exportable at any time. As a result the creators feel and communicate that this is entirely "their" site, if that makes sense.

Pivotuner[0]: automatic real-time pure intonation and microtonal modulation This is an audio plugin which I've been working on over the past couple years, I've gotten input from some pretty high-profile artists like Jacob Collier! Finally released it publicly late last year. Pivotuner is a plugin which tunes MIDI data in pure intonation in real time. Besides enabling beautiful purely-tuned chords on keyboards, this also enables many other cool things such as microtonal modulation, and unusual chord sonorities! (more info on the website, this is copy-pasted) Besides the demos on the website, there's some stuff on YouTube[1]. I'm good to answer any questions!

- austincassidy 4y ago
  Wow - the Baader–Meinhof phenomenon must be real. I just created my first song using automatic real-time pure intonation and uploaded it yesterday[0]. I used a plugin called Scale Breaker[1] that connects to MPE instruments in Ableton (used Wavetable for all the synths in the song since it's MPE enabled) and set the tuning to automatic Just Intonation (12T) with 5-limit symmetric aug 5th tuning. I edited all the bass notes to trigger the correct tuning for each chord so each note is automatically microtuned to be perfectly resonant. I make House music and noticed that not many people have been experimenting using real-time just intonation in the genre so I gave it a go to see what it sounds like - it was pretty fun to make. I believe perfectly resonant music is going to be really big in the next few years now that these automatic tuning plugins are available. Question: does your plugin work through modulating the notes using MPE? My understanding is that this method allows for more versatility.

  - sporkl 4y ago
    Yep, the plugin works with MPE, though I'm also planning to add support for MTS-ESP, and MIDI 2 when it has wider support. I haven't used it, but Scale Breaker is definitely a cool plugin, I do plan on stealing some features from it. Pivotuner has a step up in that it supports microtonal modulation resulting naturally from pure intonation (which is a bit of a niche case), but Scale Breaker's ability to sync across tracks is super useful and something I am planning to add. Thanks for sharing your track, it's always nice to hear things using pure intonation!

Dollero - https://dollero.app/ https://dollero.app/ I created a personal budgeting web app which doesn't store any of your financial information in the cloud. Instead your budget data is stored locally in your browser with IndexedDB and is sync'd peer to peer with your other devices using WebRTC.

- aphit 4y ago
  Looks heavily inspired by youneedabudget (YNAB). Accurate? I assume it is, since you offer an "import" from YNAB. Did you start creating this after YNAB launched their higher prices or what was the impetus? I have my doubts about there not being a dedicated app on the phone. The most important feature of YNAB is being able to easily add transactions and since you are going the route of no automated import, manual transaction adding from mobile will be CRITICAL to get perfect. YNAB's solution is really, really good in that space. How does yours compare?
  - evtaylor 4y ago
    Thanks for taking a look at Dollero. I've been a YNAB Classic (YNAB4) user for almost a decade but was disappointed when they moved to a SaaS cloud based model (even though I understand their motivations). I enjoyed not paying a monthly fee and that syncing was supported through Dropbox where I had full control of my data. YNAB Classic hasn't been supported for a while and I didn't want to wait around for an OS update to kill it so I created Dollero. I enter most of my transactions on my phone and I agree that the mobile experience is key. Dollero is a responsive PWA so it can be used offline and can be installed by "Adding to home screen" on a mobile device resulting in an experience that is very similar to a native app. I'm continuing to polish and improve that part of the app. YNAB is a great product and is ideal for people who are new to budgeting and desire an automatic bank account import. Dollero is for people who want an envelope budgeting system, like YNAB, but are price sensitive and value their privacy. Dollero is free to use. Data syncing between devices will be a small monthly fee (currently free while in beta) making it much more affordable than YNAB, especially for folks in low income countries. Dollero respects your privacy, your data stays in your browser and is synced directly between your devices. For existing YNAB users I've added back some features that were removed from the new YNAB like multi-month view and carrying negative category balances.

https://SimplifyRecipe.com https://SimplifyRecipe.com The people who use it, love it, but I’m still learning how to tell the story well. The iOS shortcut instantly turns any recipe page into a consistent, usable cooking experience. I’m open to any feedback/ideas about how to tell that story better!
- deevus 4y ago
  This is great. Love the idea. Finding the recipe in a blog post has become a meme at this point, so this tool is invaluable. I tried it with my favourite sourdough recipe and it didn't handle HTML encoded apostrophes. They display as 's I imagine other HTML encoded entities might also be handled this way.
  - iambateman 4y ago
    Mmm thanks for trying it out! I’m working on getting the encoding right while maintaining DB security. This is definitely an issue, though.
- deevus 4y ago
  With regards to the story, I think you should lean heavily on how bad recipe blog posts are. They try to tell you their whole life story before getting to the actual recipe. Your tool removes all the rubbish and cruft.
- agentwiggles 4y ago
  I think the best way to promote it would be to write a 1000 word essay about how when you were a little kid, you just loved to hang out in the kitchen and read recipes with Grandma, and a long description of your family's Christmas traditions, a few reviews of your favorite albums, and some amateur poetry. Put all this content at the top of the page. Intersperse several ads for kitchen products, electric shavers, and grey market Cialis. After all this, throw a sentence at the bottom describing your product and add a link. You're sure to get thousands of hits! Just kidding obviously. This is a fantastic idea.

https://scipipe.org https://scipipe.org - A pipeline tool for shell commands by a declarative flow-based API in Go Github link: https://github.com/scipipe/scipipe https://github.com/scipipe/scipipe There are many pipeline tools for shell commands, but a majority has one or more limitations in their API which makes certain complex pipelines impossible or really hard to write. We were pushing the limits of all the tools we tried, so developed our own, and implemented it in Go, with a declarative API for defining the data flow dependencies, instead of inventing yet another DSL. This has allowed us great flexibility in developing also complex pipelines, e.g. combining parameter sweeps nested with cross-validation implemented as workflow constructs. SciPipe is also unique in providing an audit report for every single output of the workflow, in a structured JSON format. A helper tool allows converting these reports to either an HTML report, a PDF, or a Bash script that will generate the one accompanying output file from scratch. An extra cool things is that, because the audit reports live alongside output files, if you run a scipipe workflow that uses files generated by another scipipe workflow, it will pick up also all the history for the input files generated by this earlier workflow, meaning that you get a 100% complete audit report, even if your analysis spans multiple workflows! (More on the audit/provenance report in this post: https://rillabs.com/posts/provenance-reports-in-scientific-workflows https://rillabs.com/posts/provenance-reports-in-scientific-w... )

greazy 4y ago
Very interesting. This is like snakemake but with go. The audit trail is very interesting, especially for certified version controlled pipelines. Is it being continually developed?
- samuell 4y ago
  Thanks for kind words! Yes, although conceptually it is even more similar to Nextflow. That is, it is push-based and dataflow-based, whereas Snakemake is pull-based, quite similar to Luigi (well, hey, we also developed the SciLuigi plugin to make Luigi a tad bit more data flow-like, although only on the surface). I'm maintaining and continuing to develop SciPipe, although pretty slowly at the moment, due to a day job that doesn't allow much time to spend on it. I and a former colleague at pharmb.io who is still using it are having some plans for further features to streamline the authoring experience more though, and I'm actually looking to move to a job (e.g. in academia) that will allow me to work on it a bit more on the side.

https://mmabetsharp.com https://mmabetsharp.com A website to help make informed bets on the UFC. It presents a lot of relevant data if you're serious about MMA sports betting. I made this during the pandemic and tried to promote it through Reddit and Twitter, but it mostly fell flat and ran out of steam. I only scratched the surface of what I intended here. The data on the site is a bit outdated since neither I nor anyone has used it in a while. A bit bummed that it never caught on within the MMA capping community, but I've felt I could always come back to it if the potential expressed itself.

hnrodey 4y ago
This is rad. I'd love to see it updated with current data. I've tried to bet on MMA with mixed results, but ultimately tried to find a data driven approach to place wagers. My approach would net me tons of open browser tabs trying to track down stats about each fighter :( I really like what you've done.
- sinker 4y ago
  Thanks I really appreciate that. MMA (UFC specifically) is still wide open to advantage betting because lines are often highly narrative-based. Data itself WRT to MMA is often misleading though for so many reasons (e.g., low quality of opponents presenting a skewed perception of fighter ability). However, looking at specific things is often quite useful. The submission charts section of the site was particularly useful to me. You find that some fighters are skilled at one specific submission and that sometimes their opponents are highly vulnerable to that particular submission. A big issue I found when trying to market the site was that, the majority of bettors have no interest in looking at data, reviewing fights, or putting any time towards making informed bets. Most people prefer to place bets naively primarily for the sake of entertainment.
  - jjxw 4y ago
    I think an interesting observation here is that the very thing that makes it difficult to get adoption of this product/data is the thing that makes the product/data valuable. Without the naive/narrative/entertainment bettors it would be more difficult to find an edge. Presumably there is a very small, niche population that would find this information very valuable. Funnily enough, those that do find it valuable are unlikely to share it - if they're acting in their own self interest they don't want other sophisticated bettors to enter the market and inadvertently help the bookies set the line more accurately.

https://www.twitch.tv/watchmeforever https://www.twitch.tv/watchmeforever - AI-generated (aside from the artwork) parody of '90s sitcoms, running forever (24/7/365). We worked on this w/ a very small team for the past four years, in-between our day jobs. When started, OpenAI didn't have an API, and Stable Diffusion definitely wasn't a thing, so we had to come up with novel methods to thread cohesive content together. Most of the "creative" details e.g., laugh track, dialogue, frequency of dialogue, camera shots, and so on, are all tunable on a per scene basis. We're in sort of a holding pattern right now -- no clear path to monetization for the project, and it hasn't garnered enough attention for us to probably get funding based on the technology backbone. Hope you enjoy it! Labor of love. :)

Nothing flopped, it just never reached breakout success the way I wanted. Most things I managed to get into the top 5 of the front page of HN over the span of 8 years, whether it was a project, blog posts or products but that's just a moment in time, a few hours even, it's not success.

The latest M3O.com, was a serverless API gateway, that honestly I thought as a product was great but never achieved the thing I set out for it to be.

https://github.com/a-e-k/canvas_ity https://github.com/a-e-k/canvas_ity A tiny, single-header <canvas>-like 2D rasterizer for C++ More detail -- This is an STB-style single-header C++ library with no dependencies beyond the standard C++ library. In about 2300 lines of 78-column code (not counting blanks or comments), or 1300 semicolons, it implements an API based on the basic W3C <canvas> specification to draw 2D vector graphics into an image buffer: - Strokes and fills (with antialiasing and gamma-correct blending) - Linear and radial gradients - Patterns (with repeat modes and bi-cubic resampling) - Line caps and line joins (handling high curvature) - Dash patterns and dash offsets - Transforms - Lines, quadratic and cubic Beziers, arcs, and rectangles - Text (very basic, but does its own TTF font file parsing!) - Raster images (i.e., sprites) - Clipping (via masking) - Compositing modes (Porter-Duff) - Drop shadows with Gaussian blurs I also uncovered a number of interesting browser <canvas> quirks along the way with the HTML5 port of my testing suite.

Mine is Derw: https://www.derw-lang.com/ https://www.derw-lang.com/ It's a programming language I created after frustration with TypeScript and Elm, in order to write better type-safe code in a functional manner. There's seemless interop between Derw and TS/JS, making it more useful for working with TS codebases than Elm. It's quite production ready though there are a few things left to implement, but so far there's features like: - A formatter - A test framework - A benchmarking framework - A web framework for writing apps - VScode extensions - Type checking - Output generation for TS, JS, English, Derw and Elm - A Gitbook: https://docs.derw-lang.com/ https://docs.derw-lang.com/ I also have a very active blog where I write about Derw or programming in general: https://derw.substack.com/ https://derw.substack.com/ and the Twitter for staying up to date is https://twitter.com/derwlang https://twitter.com/derwlang

https://github.com/ipyflow/ipyflow https://github.com/ipyflow/ipyflow IPyflow is a new Python kernel for JupyterLab that understands how variables and cells depend on each other, making it easier to reason about notebook state. It adds opt-in reactivity, so that pressing ctrl+shift+enter triggers execution of all cells that depend (recursively) on the current cell. Furthermore, with its `code` function, you can see exactly what code is needed to reproduce a given variable. I started working on it after watching the famous talk "I Don't Like Notebooks" by Joel Grus, and, anecdotally, I like notebooks just a little more when I use this kernel :)

https://codeatlas.dev https://codeatlas.dev - codebase visualisation tool It takes your git repo and generates a beautiful visual representation of the actual code that's in it. Sort of an alternative navigation tool (in addition to IDEs) for large codebases. You can run codeatlas as part of your CI with our Github Action (https://github.com/codeatlasHQ/codebase-visualizer-action https://github.com/codeatlasHQ/codebase-visualizer-action). We made this because grokking complex software projects is really difficult and we've found that a visual overview of what's in a codebase can be quite helpful to get started. E.g. checkout https://codeatlas.dev/gallery/kubernetes/kubernetes https://codeatlas.dev/gallery/kubernetes/kubernetes for the generated visualisation of the Kubernetes Github repo! We slowed down active development after our initial attempts at dissemination didn't really go anywhere (bragging about side projects on the internet, ugh), but would still love feedback on whether this is possibly useful to anyone else! Note: The site works somewhat on mobile, but is much better on desktop!

https://moonjump.app https://moonjump.app Moonjump is a server that redirects you to a random page harvested from Are.na, Hacker News, Marginalia Search, and Gossip Web. This project aims to spark curiosity and provide a portal to the vast collection of interesting material hidden by the commercial web. The source material is aggregated with care by users of these platforms. Since this accumulation is performed by hand, pages are saved because they had an effect on the users who saved them. The goal is to find something that has an effect on you. For Are.na, the dictionary of channels that the app pulls from is weighted by the number of pages in the channel. Channels with the most pages are more likely to be selected. Moonjump makes a decision for you by selecting something random from a deep sea of unconventional content. Results may be peculiar, profound, or absolute nonsense. But you can always close the tab and jump again. The search engine is powered by Marginalia. I have to admit that the existence of Marginalia is a huge inspiration for Moonjump. Search queries on Moonjump use the Marginalia API to redirect you to a random result. The easiest way to jump is to click the large logo at the center of the homepage. You can also add https://moonjump.app/jump https://moonjump.app/jump to your bookmarks bar. If you are an OSX user and have hammerspoon installed, check the github repo for instructions on how to jump via a keyboard shortcut. github: https://github.com/ya1sec/moonjump https://github.com/ya1sec/moonjump

I think that anyone who likes hard puzzles and spending many hours/days to solve some levels will enjoy it. Also, if one happens to be a programmer that struggles with recursion, I think the game might help with that regard, but being a programmer is not a requirement to play.

The gameplay and UI need work, but I thought the graphics were interesting. All the units are rendered as Mandelbrot and Julia sets on the GPU. Parameters are varied in real time to make the fractals look like they are moving and swimming. Another fun thing is the audio effects were made with an electric guitar. Thanks for reading :D

deevus 4y ago
You might get some more eyes on your game if you released it on Itch. It seems to me that it would fit better with the gamejam scene than general consumption. With my amateur game design hat on (discard if you please): I think that the game could be much improved with a drum track to make playing the game feel more zen. I get the vibe that it isn't a game that you "play" but more of a time killer. It would be extra cool if the audio effects could play in time with the drum track, too. The player could be composing a song as they play.

Didn't want to do ugly domain parking pages, but also didn't have time to develop them. I wanted something useful and something that still offered value. Newsy creates an automated content aggregator (think of Reddit but automated) for your domain based on the keywords you describe. Over the years, a lot of features went in including newsletter, membership etc. The best option for the users was providing ways to monetize - including bringing your own ads, charging for posts, paid membership etc.

The sysadmin/ops overhead associated with getting something useful out of log aggregation and analysis is so much lower than tools like splunk and elasticsearch. If you're interested in getting some kind of log analysis/aggregation spun up quickly and don't need all the complexity associated with things like ES and splunk, definitely give it a test drive.

The thing below - one of the links at the bottom goes to its "Show HN" page, where people can check that only received 4 points. Many people discuss REPL tricks here, so I didn't expect it to flop so miserably... Show HN: Eev and TikZ, or: how to learn TikZ using a REPL (twu.net) Hi all, I made a video that at first sight is about a way to use REPLs to explore TikZ - and TikZ is a huge (La)TeX package for drawing graphics... At second sight that video is about a series of tricks for using REPLs in Emacs, and TikZ is just an excuse to present them. As far as I know those tricks are very unusual; they implement a kind of "meta-REPL" that controls other REPLs, and they do that in a way that is much simpler, and much easier to hack, than Org's code blocks and than the cells in Jupyter notebooks. The page has lots of screenshots and links, and it has instructions for downloading the video and its subtitles, and for reading the subtitles in plain text. I tried to make everything as accessible as possible for the people who just want to watch the the first two parts of the video - "Introduction" and "Trying it" - in super-high speed.

My target was under 1 second. After the board is built where all the numbers are random, then the code removes numbers also randomly in order to play the game. That randomness turned out to be a nice little challenge :-) It seems to work okay for the most part. Myself and other family members play it often now.. which is really cool. There are no scores. If you guess wrong there is no penalty. Just low key, low stress game.

The only FOSS thing I've done that I think is really worth telling people about is KaithemAutomation, a home automation server in pure Python with a bit easier setup than Home Assistant, and some features aimed at commercial installs like room escape control, and some pretty decent network video recorder features. https://github.com/EternityForest/KaithemAutomation https://github.com/EternityForest/KaithemAutomation I put 6 years or so into it, and have used it on plenty of contract projects, but so far I don't think anyone else is interested. Possibly because it's largely UI and CRUD over existing functionality, and there's not much particularly exciting to the hacker community, few interesting algorithms, it's not minimalist at all, etc. Plus it has a lot of dependencies that might or might not exist outside of Debian, I've never looked into how it would run on the more DIY distros since I've never used them.

You can do initial contentful rendering and realtime DOM updates from the server over http and websocket with only 6.5K of js minified (22x smaller than react, 2.6x smaller than svelte). It was inspired from the Phoenix Liveview but evolved to adopt TSX with explicit DOM updates with querySelectors (without vdom diff-ing). Unlike most js frameworks, it is a starter template, not a package. So you’re free to modify and extend / trim it to better fit your need.

TrickardRixx 4y ago
I see in the repo you mention wanting to add support for archiving. I'd really like to see a sort of master playlist for a genre. Just keep adding the songs from each weekly playlist to the master genre playlist, then the "date added" field could be used for looking at the playlist historically. You lose duplicates this way, so maybe not the best archival strategy, but with the master playlist you could have hours of music instead of an hour.

This is not nearly as impressive (or useful) as the other posts, but when ChatGPT was released I developed this toy site almost entirely thru prompts. http://goodvibeai.com/ http://goodvibeai.com/ I told it to gen a bunch of heartwarming messages, make a website to display them, now make it have a color gradient, now make the text fade in and out, now have the site have a button to play an audio file, etc etc etc Spent more time hosting it via GitHub than making the site, really blew my mind in terms of the creation process.

I tried with my web app https://collanon.com https://collanon.com and didn't get much traction on HN(maybe bad timing). It's on its 3rd year of development/improvement and it's about making and sharing easily private discussions and confrontations(1vs1) with temporary/total anonymity in mind without relying on any big tech service or cloud providers to keep the data more private. I'm on a path to a big upgrade soon too.

This is incredibly useful! Is it possible to make this into a simple (single page) shopping list? Where I type my shopping list, product recommends substitutes with lower sugar — and gives me distribution (histogram) of main ingredients for my shopping list. That would be life changing.

https://yakubin.com/notes/comp/reserve-and-commit.html https://yakubin.com/notes/comp/reserve-and-commit.html In-depth analysis of a memory allocation strategy, which allowed me to write an alternative to std::vector, which in my benchmarks performed better for all but a few workloads and on those few was competitive. I was exhausted after finishing it. It may have been too long for some folks though. No upvotes.

xanthine 4y ago
It is indeed a bit too long. A few tips: - Graphs of benchmark results would be neat to have. Remember to put the code and graphs as a sort of TL;DR in that blog post. - I skimmed the code; there's no clear instructions as to how I'd use it for my own projects. Perhaps work on a CMake / Autoconf config for a library build? - The repository itself might not have enough visibility due to being self hosted. While I do love self-hosting, maybe posting a read-only mirror on GitHub would bring in more exposure?
- GrumpySloth 4y ago
  > Graphs of benchmark results would be neat to have. Remember to put the code and graphs as a sort of TL;DR Thanks for the suggestion. I’ll use it when I get around to updating this page. For now though I’ll let it sit there, as I’m too tired with it at this point. > there's no clear instructions as to how I'd use it for my own projects. Perhaps work on a CMake / Autoconf config for a library build? It’s not meant to be used as a library. It’s only for demonstrative purposes. There are a couple choices made in this code motivated by that, like not checking for integer overflow, or hardcoding page size based on the target platform at compile time. If someone wants to use the code anyway, they should just copy it into their project and possibly modify the parts which aren’t up to snuff. That’s also what I’m doing, as I wrote a more robust version in Rust for my project. I only wrote C++ for the article, because that’s what more people are familiar with, and there are more implementations, so I got to benchmark this code against several implementations of std::vector. As for CMake/Autotools, I think the scripts in the repo are better for my little demo, as they don’t add any dependencies beyond what’s already available on each platform, they’re more transparent and easier to use. For a big project I’d probably use CMake, but I don’t think it’s warranted here. > The repository itself might not have enough visibility due to being self hosted. While I do love self-hosting, maybe posting a read-only mirror on GitHub would bring in more exposure? The intended path of discovery, when it comes to the repo, is through my article. It’s not meant to be independent, so I don’t really care about the discoverability of the repo as a stand-alone thing. As for GitHub, I don’t like it for a variety of reasons and if I can help it, I’ll avoid it.

I created Scheme for Max and Scheme for Pure Data. They are extensions to the Max/MSP, Ableton Live, and Pure Data computer music environments that embed an s7 Scheme interpreter in the host so that you can script, automate, and live code the hosts with s7, a Scheme from the CCRMA computer music center at Stanford and the same one used in the Snd editor and the Common Music 3 algorithmic composition environment. This allows you to do things like write algorithmic music tools, sequencers, and use the Ableton Live API in Scheme, including with Common Lisp style macros. It has an API for integrating with Max to share data structures, hook into the scheduler, run in the high priority thread, and so on. (The Max javascript object does not run in the high thread and so while it is similar in scope, it can't be used for accurate timing, so is no good for sequencing or live algorithmic generation.) S4M allows you to do all the goodness of high level music programming in a Lisp, without losing the ability to use modern commercial tooling and instruments. It's my thesis project for a Masters in Music Technology with Andy Schloss and George Tzanetakis at the University of Victoria, and I plan to continue to a PhD working on it. I tried submitting twice, but it never made the page, which surprised me a bit given Lisp interest here.

A few years ago (~2017) I created a tool in the biomedical domain to design peptide vaccines. https://www.padiracinnovation.org/en/peptide_PoC/ https://www.padiracinnovation.org/en/peptide_PoC/ Peptide vaccines are not very efficient, but they can be easily designed to address a large number of diseases. Basically I would like that a pharmacist could use this tool with just 2 days training. How it works? If you know that a certain protein is produced by a certain type of malign cell and only by those cells, a peptide vaccine will cause the human immune system to try to eliminate the cells that produce that protein. The most obvious use is in the case of some cancers cells which produce a certain protein. These proteins are named "tumor specific antigen". It is an antigenic substance which is produced only by tumor cells. Tumor antigens are useful tumor markers in identifying tumor cells that are targeted by the immune system when it is primed by a peptide vaccine. Another interesting thing is that cancerous cells evolves quickly to try to evade therapies, here it's very easy to design a new peptide vaccine, for example every week. As the name hints at, it's a proof of concept, I designed several variations. A good thing is that you don't need a lot of CPU power to run it. I use a cheap VPS from OVH. I have written a large documentation here: https://www.padiracinnovation.org/en/peptide_PoC/doc/documentation_en.html https://www.padiracinnovation.org/en/peptide_PoC/doc/documen...

As a hobby project, I run Code::Stats[0]. It's a website that tracks what languages you are programming in (via editor plugins) and gives you a profile page with various statistics[1]. It's ad-supported (with EthicalAds) to deal with server costs, or you can buy a support account to remove ads. The site and all the editor plugins are open source, the site is written in Elixir (but I'm looking at integrating Gleam in the future). Currently it's completely a free time thing; I make negative money on it. My dream would be to have enough paying users to work on it part time (even a little), but that's far away and may never happen.

efreak 4y ago
Looks useful. I currently use untrackme, unalix, and link eye (the older version for which source is no longer available, not the new one). Feedback: I've submitted some comments on GitHub, but I'll go ahead and include some more here: - I'm not a fan of this UI; it seems both somewhat cluttered and small. I'm on tablet, fwiw. Consider a fullscreen UI with indicators for modules that can be activated by the current URL, rather than always showing all active modules. At the bottom of the screen, display either a grid or list of apps that can open this URL. This is better than hiding it away behind another tap. Perhaps have a toggle for whether the grid shows share to or open with? - consider a list of queries that will always be automatically removed from URLs, without interaction. For example, any time I share an Amazon URL, I remove everything after the asin; it would be easier if this was automatic. However these automatically removed queries should be listed in the history, so the original URL can still be obtained. - there's no option to remove hashes (#tag in the in-app example). Hashes are occasionally used with tracking as well, in combination with javascript. - Only show the modules if they're able to do something. For example, if no referrers are found, don't display the settings for that. Same for labels, queries, etc. - the pop-up goes away if I switch apps/open recents. Leaving it open would be nice. - allow sharing URLs to the app. Not all apps make it easy to directly open URLs in another app (Firefox custom tabs, for example; I use Lynket to open custom tabs, and long-pressing a link only lets me share or copy the URL)

The rest of the website is in English but the video narrations are in French, and in Example 2 it's been recorded using, as the joke goes, "a potato". 2 more things: everyone knows WASD nowadays, and I keep ending on "Example 1" because when I go to the menu, I click on it hoping it would appear, but clicking on it actually takes me back/reloads the page of Example 1... but not before the dropdown opens and letting me click Example 2/3.

https://github.com/shish/rosettaboy https://github.com/shish/rosettaboy The same gameboy emulator rewritten in C++, Go, Nim, PHP, Cython, Python, Rust, and Zig (and WIP typescript); mostly to teach myself the languages and to compare and contrast their idioms. Also, when taken with a very large grain of salt, usable as a language benchmark (As with all benchmarks, there are lots of caveats - but as far as I’m aware this is unique in being “the same code in multiple languages” and “several thousand lines of code”): $ ./utils/bench.py rs / lto : Emulated 15763 frames in 10.00s (1576fps) cpp / lto : Emulated 14737 frames in 10.00s (1474fps) rs / release: Emulated 13183 frames in 10.00s (1318fps) cpp / release: Emulated 12966 frames in 10.00s (1297fps) zig / release: Emulated 8792 frames in 10.00s (879fps) nim / speed : Emulated 8127 frames in 10.00s (812fps) nim / release: Emulated 6161 frames in 10.00s (616fps) cpp / debug : Emulated 5693 frames in 10.00s (569fps) go / release: Emulated 5040 frames in 10.00s (504fps) pxd / release: Emulated 3792 frames in 10.00s (379fps) nim / debug : Emulated 1968 frames in 10.00s (196fps) rs / debug : Emulated 1676 frames in 10.00s (168fps) py / mypyc : Emulated 887 frames in 10.01s (89fps) php / opcache: Emulated 613 frames in 10.01s (61fps) php / release: Emulated 255 frames in 10.01s (25fps) py / release: Emulated 101 frames in 10.06s (10fps) zig / safe : Emulated 40 frames in 10.00s (4fps)

Really cool! What were your impressions of all the languages you've implemented this in?
- Shish2k 4y ago
  For a few of the languages I’ve added a “thoughts on this language” section in the language folder’s README, but I only started doing that after a few implementations were already finished, so it’s a bit inconsistent - maybe it’d be worth making it consistent, and writing up as a single easy-to-read webpage, and submitting that to HN :P

https://github.com/RhetTbull/osxphotos https://github.com/RhetTbull/osxphotos A macOS command-line "multi-tool" for working with Apple Photos. Allows you to export photos (along with all the metadata), batch-edit metadata such as times and timezones, explore the AI metadata Apple computes for each photo (but doesn't make available to the user) such as "well timed shot", "pleasant composition", etc, compare libraries, sync metadata between libraries, and much more! It's written in python and provides a full python API for interacting with Photos.

Fantastic! I also used patrikhson's photo-export tool to help me restore all of my lost iPhoto Events after a strange sync issue the first time I enabled iCloud Photo Library in...maybe 2016? I was able to restore all of my lost events as albums in Photos writing code based on their script. Your tool looks incredibly useful, will def keep for some batch date fixes I need to do.

https://grizzlybulls.com https://grizzlybulls.com It's a freemium subscription service to the algorithmic trading models / hedging systems I've been developing over the last few years. 2022 performance: SPX (benchmark): -18.77% Free models: TA - Mean Reversion Basic (https://grizzlybulls.com/models/ta-mr-basic https://grizzlybulls.com/models/ta-mr-basic): -9.93% TA - Trend Basic (https://grizzlybulls.com/models/ta-trend-basic https://grizzlybulls.com/models/ta-trend-basic): -17.79% Vix Basic (https://grizzlybulls.com/models/vix-basic https://grizzlybulls.com/models/vix-basic): -20.45% Premium models: Vix Advanced (https://grizzlybulls.com/models/vix-advanced https://grizzlybulls.com/models/vix-advanced): -17.9% Vix - TA Advanced (https://grizzlybulls.com/models/vix-ta-advanced https://grizzlybulls.com/models/vix-ta-advanced): -16.14% Vix - TA Macro Advanced (https://grizzlybulls.com/models/vix-ta-macro-advanced https://grizzlybulls.com/models/vix-ta-macro-advanced): -3.15% Vix - TA Macro Monetary Policy Extreme (https://grizzlybulls.com/models/vix-ta-macro-mp-extreme https://grizzlybulls.com/models/vix-ta-macro-mp-extreme): +0.56% The models use no leverage and are always either 100% long the S&P 500 or 0% long (in cash). These are not HFT, averaging one trade per 2-4 weeks on average depending on the model. You can see active signals for the free models by checking the site frequently, or if you subscribe to one of the premium plans you'll get email or text notifications as well. In 2022, all but one of the models beat the SPX on an absolute performance basis, some substantially so with the top model returning positive absolute returns with a +19.33% outperformance gap. However, it was still a much worse year than 2021 as the unprecedented reversal of Fed policy in response to 40 year high inflation proved to make a challenging backdrop. Full 2022 performance report: https://grizzlybulls.com/blog/models-performance-update-q4-2022 https://grizzlybulls.com/blog/models-performance-update-q4-2...

https://crowdview.ai https://crowdview.ai - search engine for forums and discussion sites Like many of you, I find Google results to be full of SEO spam and have resorted to adding "site:reddit.com" or "site:news.ycombinator.com" to all my queries (since 2015!). Otherwise, it's really hard to figure out "what does a genuine, real life human think about this thing?". But limiting my results to just Reddit isn't ideal because so much great content exists elsewhere. Lots of great information and conversations have moved elsewhere, and niche forums are still alive on the web! But it's impossible to find these places because they rank so poorly on Google. So I built a search engine across a curated list of these, making sure to remove any kind of SEO junk (blog spam, listicles, etc). There's also a chrome extension that surfaces these results alongside Google, so you don't have to remember to keep coming back. Please try it out and share any feedback! (and if you're interested in this topic, join the Slack)

Also includes components for per-tenant data isolation with EF Core without having to pollute your code with a bunch of "where" conditions.

Splink - a FOSS python library for probabilistic record linkage (fuzzy matching/entity resolution). Splink is dramatically faster and works on much larger datasets than other open source libraries. I'm particularly proud of the fact we support multiple execution backends (at the moment, DuckDb Spark Athena and Sqlite, but additional adaptors are relatively straightforward to write). We've had >4 million pypi downloads and it's used in government, academia and the private sector, often replacing extremely expensive proprietary solutions. https://github.com/moj-analytical-services/splink https://github.com/moj-analytical-services/splink More info in blog posts here: https://www.robinlinacre.com/introducing_splink/ https://www.robinlinacre.com/introducing_splink/ https://www.robinlinacre.com/splink_3/ https://www.robinlinacre.com/splink_3/

- otsaloma 4y ago
  The data frame is a Python dict and I consider that a feature so that users know how to e.g. loop through columns with .items() etc. That then means that bracket notation is reserved for column names only (i.e. dict keys). So, that's why a separate function is needed.

I’m an introvert – made an app to help maintain connections with people. Landing page is at https://communiqai.com https://communiqai.com and it's also on the Play Store at https://play.google.com/store/apps/details?id=dev.mtc.ga https://play.google.com/store/apps/details?id=dev.mtc.ga. CommuniqAI is an intelligent tool for scheduling and automating SMS text messages, calls and email. It’ll help you stay in touch with those who mean the most to you—and it’ll be there for you through life’s many distractions. Let’s face it, some of us are better at communicating than others. Rather than forgetting or being “too busy” to reach out to those who are important to you, CommuniqAI will cleverly send text messages of your choosing to, and smartly prompt you to call and email, the people you care about. Whether that person is a significant other, family member, friend, or even a patient, CommuniqAI will help you stay in constant contact. Some people are, very much, against automation technology like this, but I believe that anything that can help keep communication high between loved ones is, in the long run, a good thing. CommuniqAI, by default, will not take any action and largely act as a helpful reminder.

Cool! Personally, I have set reminders to reach out to friends and family on my phone. I can therefore relate. The landing page communicates the honest intent behind this very well! If I were to use your product, I wouldn’t want to cycle through canned messages. Do you plan on making this truly AI-powered? That would be a game changer. Let your app draft both kind messages and responses, and allow the user to review and edit before sending. Then make it learn from those edits, and boom, you’ve built a personal social assistant. For now something more practical: as a typical user, I am not interested in my timezone. No need to show that specifically in such a large font.

I don't know about everyone else, but to me programming with just the "subtract and branch if less than or equal to zero" instruction sounds way, way more frustrating than something like the TIS-100.

Recently, I wrote a blog post on KHyperLogLog (https://pncnmnp.github.io/blogs/khyperloglog.html https://pncnmnp.github.io/blogs/khyperloglog.html), which is a data structure that estimates the privacy risks of very large databases. If you're interested in this topic, I have also written about: * Approximate Distance Oracles (https://pncnmnp.github.io/blogs/distance-oracles.html https://pncnmnp.github.io/blogs/distance-oracles.html), and * Spectral Bloom Filters (https://pncnmnp.github.io/blogs/spectral-bloom-filters.html https://pncnmnp.github.io/blogs/spectral-bloom-filters.html) I am currently working on more blog posts. Stanford's CS166 Suggested Project Topics (https://web.stanford.edu/class/cs166/handouts/090%20Suggested%20Project%20Topics.pdf https://web.stanford.edu/class/cs166/handouts/090%20Suggeste...) are a huge inspiration.

I wrote a blog post about using job post data to predict startup fundraises: https://www.coolstartupjobs.com/blog/predicting-startup-fundraises https://www.coolstartupjobs.com/blog/predicting-startup-fund.... You can predict a decent chunk (~25%) of fundraises with this approach! That was originally for a job board, but job boards are very saturated. I've pivoted to a data newsletter for startup investors to identify companies that are fundraising before you read about them on techcrunch: https://startup-spotter.beehiiv.com/ https://startup-spotter.beehiiv.com/

Clever pivot! I was recently thinking it would be useful to track job posts that have been open for a long time. This could be a sign that the company is struggling to make a hire. As a freelance developer, that suggests they may be open to a cold call offer for a contract until they can fill the role. The hiring manager may be more receptive since the seat has been vacant for a while, and they can end the contract when the role is finally filled. Is that something you can build on top of your dataset?

https://trycereal.com https://trycereal.com - Membership platform for creators that want their own site. We made Cereal to help content creators find more independence in running their own content business, by centralizing their content on their own site and offering subscription/monetization. It's been great, creators are able to monetize their customers without being on a 3rd party platform with ridiculous fees, or base their entire income on ads.

carlosjobim 4y ago
Interesting project! You write that creators can monetize without having to be on a 3rd party platform, but on you pricing page it shows that clients have to pay extra to use their own domain - so how are you not a 3rd party platform?
- jamalone 4y ago
  Thanks! Great question, and I should have been more clear in my terminology. We're more like a site builder + hosting provider than a general platform. The difference is between us hosting them directly i.e. Squarespace, and their presence on a platform where they are in a larger pool of creators and their branding is secondary i.e. Patreon/YouTube. The key is that even on our lowest tier there is no cross site discovery, the only presence of our branding is in the footer, and their membership list is exportable at any time. As a result the creators feel and communicate that this is entirely "their" site, if that makes sense.

Pivotuner[0]: automatic real-time pure intonation and microtonal modulation This is an audio plugin which I've been working on over the past couple years, I've gotten input from some pretty high-profile artists like Jacob Collier! Finally released it publicly late last year. Pivotuner is a plugin which tunes MIDI data in pure intonation in real time. Besides enabling beautiful purely-tuned chords on keyboards, this also enables many other cool things such as microtonal modulation, and unusual chord sonorities! (more info on the website, this is copy-pasted) Besides the demos on the website, there's some stuff on YouTube[1]. I'm good to answer any questions!

Wow - the Baader–Meinhof phenomenon must be real. I just created my first song using automatic real-time pure intonation and uploaded it yesterday[0]. I used a plugin called Scale Breaker[1] that connects to MPE instruments in Ableton (used Wavetable for all the synths in the song since it's MPE enabled) and set the tuning to automatic Just Intonation (12T) with 5-limit symmetric aug 5th tuning. I edited all the bass notes to trigger the correct tuning for each chord so each note is automatically microtuned to be perfectly resonant. I make House music and noticed that not many people have been experimenting using real-time just intonation in the genre so I gave it a go to see what it sounds like - it was pretty fun to make. I believe perfectly resonant music is going to be really big in the next few years now that these automatic tuning plugins are available. Question: does your plugin work through modulating the notes using MPE? My understanding is that this method allows for more versatility.

  Yep, the plugin works with MPE, though I'm also planning to add support for MTS-ESP, and MIDI 2 when it has wider support. I haven't used it, but Scale Breaker is definitely a cool plugin, I do plan on stealing some features from it. Pivotuner has a step up in that it supports microtonal modulation resulting naturally from pure intonation (which is a bit of a niche case), but Scale Breaker's ability to sync across tracks is super useful and something I am planning to add. Thanks for sharing your track, it's always nice to hear things using pure intonation!

Dollero - https://dollero.app/ https://dollero.app/ I created a personal budgeting web app which doesn't store any of your financial information in the cloud. Instead your budget data is stored locally in your browser with IndexedDB and is sync'd peer to peer with your other devices using WebRTC.

aphit 4y ago
Looks heavily inspired by youneedabudget (YNAB). Accurate? I assume it is, since you offer an "import" from YNAB. Did you start creating this after YNAB launched their higher prices or what was the impetus? I have my doubts about there not being a dedicated app on the phone. The most important feature of YNAB is being able to easily add transactions and since you are going the route of no automated import, manual transaction adding from mobile will be CRITICAL to get perfect. YNAB's solution is really, really good in that space. How does yours compare?
- evtaylor 4y ago
  Thanks for taking a look at Dollero. I've been a YNAB Classic (YNAB4) user for almost a decade but was disappointed when they moved to a SaaS cloud based model (even though I understand their motivations). I enjoyed not paying a monthly fee and that syncing was supported through Dropbox where I had full control of my data. YNAB Classic hasn't been supported for a while and I didn't want to wait around for an OS update to kill it so I created Dollero. I enter most of my transactions on my phone and I agree that the mobile experience is key. Dollero is a responsive PWA so it can be used offline and can be installed by "Adding to home screen" on a mobile device resulting in an experience that is very similar to a native app. I'm continuing to polish and improve that part of the app. YNAB is a great product and is ideal for people who are new to budgeting and desire an automatic bank account import. Dollero is for people who want an envelope budgeting system, like YNAB, but are price sensitive and value their privacy. Dollero is free to use. Data syncing between devices will be a small monthly fee (currently free while in beta) making it much more affordable than YNAB, especially for folks in low income countries. Dollero respects your privacy, your data stays in your browser and is synced directly between your devices. For existing YNAB users I've added back some features that were removed from the new YNAB like multi-month view and carrying negative category balances.

https://SimplifyRecipe.com https://SimplifyRecipe.com The people who use it, love it, but I’m still learning how to tell the story well. The iOS shortcut instantly turns any recipe page into a consistent, usable cooking experience. I’m open to any feedback/ideas about how to tell that story better!

deevus 4y ago
This is great. Love the idea. Finding the recipe in a blog post has become a meme at this point, so this tool is invaluable. I tried it with my favourite sourdough recipe and it didn't handle HTML encoded apostrophes. They display as 's I imagine other HTML encoded entities might also be handled this way.
- iambateman 4y ago
  Mmm thanks for trying it out! I’m working on getting the encoding right while maintaining DB security. This is definitely an issue, though.
deevus 4y ago
With regards to the story, I think you should lean heavily on how bad recipe blog posts are. They try to tell you their whole life story before getting to the actual recipe. Your tool removes all the rubbish and cruft.
agentwiggles 4y ago
I think the best way to promote it would be to write a 1000 word essay about how when you were a little kid, you just loved to hang out in the kitchen and read recipes with Grandma, and a long description of your family's Christmas traditions, a few reviews of your favorite albums, and some amateur poetry. Put all this content at the top of the page. Intersperse several ads for kitchen products, electric shavers, and grey market Cialis. After all this, throw a sentence at the bottom describing your product and add a link. You're sure to get thousands of hits! Just kidding obviously. This is a fantastic idea.

This is cool! I got 70 on my first try. Are there any strategies that you recommend? With 2048, once you grok the strategy, the game becomes easy. Is this the same?
- maaaaattttt 4y ago
  Thank you! Apparently the strategy (not from me) is to “make the move that gives you the fewest choices for the second move” (taken from the link a shared in a response to a sibling comment). I think the statement is meant to be recursive.

Cool idea. Got to 92 on my second try but I feel like reaching 100 would take a lot of planning and would stop being fun as a game and turn into math/chess type of challenge.
