- godelmachine 9y agoDid you buy the Zync ZedBoard yourself? How much did it cost? What are the specs?
- gvb 9y agoYou can buy it via Avnet (US distributor) for $88.99 + $8 (or so) S/H. They sent me a promotion code THXNN6W for free shipping. It is an entry level Zynq processor (single ARM core, pretty decent FPGA capabilities). It runs linux well. Remarkable learning potential for $100! https://www.avnet.com/shop/us/p/kits-and-tools/development-kits/avnet-engineering-services/aes-minized-7z007-g-3074457345632706668 https://www.avnet.com/shop/us/p/kits-and-tools/development-k... You can download the Xilinx IDE Vivado WebPack for free. https://www.xilinx.com/products/design-tools/vivado/vivado-webpack.html https://www.xilinx.com/products/design-tools/vivado/vivado-w... Both Avnet and Xilinx require creating a (free) account.
- tranvu 9y agoNothing new for me. Just trying to decouple some components from my side project from a year ago. For those interested, this is a JS/React project. The app is an open-source version of Alfred built on top of Electron/React -- https://github.com/vutran/dext https://github.com/vutran/dext While it's very difficult at the moment to work on the app itself, I decided to just extract the search component to be reused elsewhere so I've started building Omnibar (https://github.com/vutran/omnibar https://github.com/vutran/omnibar).
- zanedb 9y agoCan't wait for Windows/Linux support!
- pcmaffey 9y agoFinally getting some time to dedicate to my 5 minute word game: https://www.pcmaffey.com/01100111011000010110110101100101 https://www.pcmaffey.com/01100111011000010110110101100101
- eat_veggies 9y agoThat's a really great game! I've definitely played a game a lot like this before (same hexagon concept too) but this is executed so well. The end-game poetry is brilliant!
- askafriend 9y agoTo be honest, the very last thing I want to do when I'm on vacation is to code... I'm a professional software engineer, I do it enough day to day.
- hxnjxn 9y agoYes.
- malux85 9y agoI’m playing with some weird ideas I’ve had for Q-Learning, not sure they will work, but it’s time to play. I’m finihing up some satellite imagery stuff to go into my product https://hydrachain.io/ https://hydrachain.io/ and I bought Id spend a bit more time reading Quantum Computing since Democratis because I’m finding it quite a challenging book and I love it
- caleblloyd 9y agoAdding rule-based sticky routing to the Traefik reverse proxy. The idea is to write rules to route all requests matching a certain URL, query string, or HTTP header to the same backend server. This would allow for caching or synchronization in a distributed application to happen in memory on an app server instead of always going back to the database or Redis. https://github.com/containous/traefik/pull/2613 https://github.com/containous/traefik/pull/2613
- ar-nelson 9y agoBuilding a new programming language, Jaspr: https://github.com/ar-nelson/jaspr https://github.com/ar-nelson/jaspr It's not nearly done enough for its own HN post yet, but it's coming together slowly. Still working on the standard library and documentation.
- pascalxus 9y agoI got tired of building side projects that never get used by anyone, so I'm taking a market first approach. If anyone is interested in reading about Nutritional density to find out what foods have the highest nutrient count per calorie, check out: https://kale.world https://kale.world
- tonyarkles 9y agoI read it top to bottom and found it super interesting. I appreciate the normalization factor! I'm chuckling a bit though. "Nutrients per calorie" is a fantastic metric, but then I got to wondering... "How much spinach is necessary to reach 200 cal?" http://www.caloriegallery.com/foods/calories-in-spinach.htm http://www.caloriegallery.com/foods/calories-in-spinach.htm suggests that it'd be 870g! Almost 2lb! That's a lot of spinach to eat. So is the ultimate goal to be able to put together daily meal plans that ensure you hit all your micro requirements?
- pascalxus 9y agoYup, that's exactly right. I'd like to build a tool that puts together meal plans that help people meet their nutrition goals. But, I thought I'd build up an audience first, to see if there's interest. Yes 2 LBS of spinach is a lot. At costco they sell those 2.5 lb bags and their pretty big. But, keep in mind, if you boil it down in a big pot, 1 lb of spinach isn't so insurmountable, as the spinach becomes really small: best of all it only takes a minute of cooking.

- unrealornament 9y agoI am working on a web based successor to the Kid Pix painting program that I loved as a kid. I hope today's kids love it just as much!
- rufius 9y agoThis is a non-answer but in reality - not a damn thing. Been working really hard lately so it’s time to recharge and read a couple books.
- chadbaud 9y agoTrying to figure out how to market my side project. https://www.printpost.co https://www.printpost.co Any suggestions welcome.
- AngeloAnolin 9y agoNice idea. I was thinking of doing the same before and calling it "Printstagram".
- zanedb 9y agoMaybe a Show HN post at least?
- eat_veggies 9y agoYou could buy some Instagram ads or run some promotions (e.g. "post a picture with the hashtag #printpost for a chance to get it printed").
- is0tope 9y agoI'll be working on finishing off a small practice project for viewing cryptocurrency mentions vs price on reddit. http://bitreddit.com http://bitreddit.com
- AngeloAnolin 9y agoNot sure if this counts as hacking, but I am targeting to learn Elm. Starting with the Elm: Getting Started [11] pluralsight course by Mike Van Sickle. [1] https://www.pluralsight.com/courses/elm-getting-started https://www.pluralsight.com/courses/elm-getting-started
- SirLJ 9y agoTrying to see if there is a sports betting opportunity in NHL with the new rules generating more goals... newer bet on a sports event in my life until a week ago, so it looks fun...
- mipmap04 9y agoI'll be launching my phishing simulation SaaS in a week or so: www.phishero.com
- kiwijamo 9y agoNot sure if it counts. I'm working on making public several hundreds (if not thousands) of photos of cell sites from around the world (but mostly in my home country of New Zealand). Using Caddy as a webserver. Pages will be in plain Markdown (which Caddy will render into HTML along with a reference to my homegrown CSS). Not sure yet where I'll host it but perhaps in a Hyper.io container or in a VPS I already have running for other sites. Photos will be hosted on Backblaze B2. Nice simple project that I've been putting off for years.
- jwho82 9y agoPicking away at Symfony 4, Ionic 3 and finishing up some Quickbooks integrations with my time tracking SaaS.
- hxta98596 9y agoOur website promoting local short-term small businesses like popup shops and food trucks and "summer businesses" launches January 1. Our first feature story is an article and podcast interview about the Christmas tree store popup business. We are working on several feature stories about "summer businesses" that people like school teachers start and run during summer holiday months before going back to their "real" job in September.
- jlizzle30 9y agoI've been thinking about prototyping a Firebase clone that uses a relational database and SQL syntax. Instead of subscribing to "nodes" you would subscribe to queries. Anyone know if this exists already?
- cjbprime 9y agoHow would you (as the DB author) know when a query has updated results?
- jlizzle30 9y agoSomething like this: subscribe ('SELECT * FROM tableA', callback) On the initial subscription, 'callback' would be called once for each row in 'tableA', then again when a row is inserted or updated. It would be the same as Firebase in this respect.
- cjbprime 9y agoNo, you as the person writing this new database, not you as the user of the API.
- eat_veggies 9y agoNot OP but I would watch for mutations in the subscribed columns, then test the changed rows on the query's constraints and fire an event if it satisfies them. I'm sure there is a more clever/efficient way of doing this though, and I can't wait to see how he/she implements it.

Then there's this write-up of someone replacing rethinkdb with postgres for live queries - (including a link to some code) http://blog.sagemath.com/2017/02/09/rethinkdb-vs-postgres.html http://blog.sagemath.com/2017/02/09/rethinkdb-vs-postgres.ht... Have you any plans already of how you will go about this?
- anthk 9y agoPlaying with C, flite 2.0 API (really easy) and Frotz. Hope I can create a TTS enabled z-code interpreter soon.
- DoreenMichele 9y agoVersion number 3 of this project with a new name and new organization of info based on a clearer conceptualization. I am fairly pleased with this take on it: http://worldwidewebworks.blogspot.com http://worldwidewebworks.blogspot.com
- pascalxus 9y agoI'll be working on my Test Case automation service. It'll make play/record web testing a breeze. https://swif.club/?s=hw https://swif.club/?s=hw
- dukeflukem 9y agoSet up an ETH node. Maybe write a smart contract. Research mining altcoins, see if it would be profitable.
- newusertoday 9y agovirtual keyboard for amazon fire tv on mac
- lawrencewu 9y agoI'm working on better automation and alerts for my newsletter, Daily Coding Problem (https://dailycodingproblem.com/ https://dailycodingproblem.com/). Specifically, I set up a bot on Slack and now I want it to message each day's stats (emails sent, open rate, click rate) as well as notify on events (subscribe/unsubscribe, email). I'm also working on a new landing page!
- 1mike12 9y agoEven though I know I should focus on my simple projects, what I can't wait to get back to is this on demand/ peer to peer "micro consulting" marketplace. I want to be able to get help in home maintenance, car repair, or any other real world query and get someone to show up and guide me through it via a video call. Even though we now have great diy websites and YouTube videos about just about everything, it's one directional. If you have a specific question or if your situation is slightly different, then you're in for hours of digging around, or giving up. It's also fun to make use of new technologies I don't get to play with at work like webrtc,react native, node etc
- jwdunne 9y agoI have a laptop coming after Christmas. I've got plans to pick up Elm, practice some of my core fundamentals and help my sister's e-commerce business.
- roryisok 9y agoPorting FlatNote, my text/md based OneNote/ evernote alternative to mac. Notes are stored in dropbox as plain text files. The app itself is basically just a markdown editor with a file tree, autosave and a list of recent files. I'm currently playing around with various display modes for content, so if it sees a list it will render checkboxes which can be tapped to mark an item as ~complete~ My philosophy is that everything should be 100% open on the platform so you can just walk away with your data with minimal effort. FlatNote files will always be readable as markdown by any other app with no 'export' required
- matchmike1313 9y agoWorking on an in-app PDF viewer in a react side project. I am working with PDF.js and experimenting with tracking page views, per page views, and total time interacted with a document. Once I have that initial data I would like to use some nice charts from ReCharts to really make the data look pretty.
- binarynate 9y agoThis isn’t holiday-specific, but over the next week I’ll be knocking out more features that are currently missing from my VR web browser app for iOS and Android: https://www.viewport.org https://www.viewport.org
