Curious what other people are learning these days

mouse_ 3y ago
I find Gnome 46 to be very promising (proper font rendering on hidpi displays as well as an actual tray, finally) so I'm learning GTK4 + libadwaita app development.
account-5 3y ago
Dart/Flutter currently, for cross platform application development. Not adverse to learning native languages or the various web frameworks, I just wanted to have one codebase across multiple platforms. I discounted the web frameworks because, as a novice, I didn't know where, or what, to begin with; I didn't want to make the wrong choice. Other than that I'm learning powershell too, mostly forced to for work, but actually it's not a bad language. On my roadmap is lua and tcl.

How to rebuild a toilet with rotting parts and replacing a whole vanity with old plumbing systems.
- betimsl 3y ago
  Highly recommended.
- Dowwie 3y ago
  Where are searching for old valves? I gave up on rebuilding old fixtures because parts were impossible to find.
  - aynyc 3y ago
    ebay and yard sales. But yes, I replaced my old tub because nothing is to spec and everything was handcrafted so none of modern parts will fit.

  What resources are you using to learn basic electronics?
  - lylejantzi3rd 3y ago
    Just the github repo at the moment, specifically the "How to make the device" page[0]. I had to search on youtube to learn what a breadboard does. I watched this one[1]. Do you (or anyone else) have any suggestions for hands-on resources? I have Practical Electronics for Inventors, but you don't build anything until Chapter 7 (Page 551). I learn better when I'm making things. [0]: https://github.com/jfedor2/screen-hopper/blob/master/HARDWARE.md https://github.com/jfedor2/screen-hopper/blob/master/HARDWAR...

    This is a bit dated, but if you are interested in general electronics (rather than digital electronics), you can try https://repairfaq.org/ https://repairfaq.org/. Digital electronics is in many ways much easier, but the analog part tends to sneak in everywhere, especially when you find your digital stuff isn't working. I think it's hard to design anything new, even digitally, without at least a working knowledge of how Ohm's law, LRC circuits, transistors, diodes, op-amps, etc. work. I don't think it was this course, but I recall checking out an impressively thick book meant for US Navy technicians. The advantage there is that the assumption (unlikely college textbooks), is that you are intelligent but not college educated, and you need to know how to work on nearly anything electronic. Again, the focus is mostly the analog side. https://archive.org/details/NEETSModule01/mode/2up https://archive.org/details/NEETSModule01/mode/2up

Rust, CUDA and JAX - I'm guessing one or more of these will be in increasing demand with a relatively high barrier of entry compared to other software tech
- sambhu 3y ago
  How are you learning these, What approach are you taking?
- abhgh 3y ago
  I have found learning JAX to be rewarding. Of course this depends on the work you do - but if you want to occasionally code out problems which involve some kind of an optimization of a differentiable quantity (without you having to work out complex gradients), JAX is perfect.

  - wruza 3y ago
    Like any completely new area. I'm exploring my options, connections and hacks that will help me to skip the muddy parts quicker. Mostly clueless and anxious atm, but it's been only a couple of months since the idea became an intent. Whole last year I was doing nothing, restoring from burnout.

More physics and mathematics. I am currently on Lagrangian mechanics and calculus of variations. Am also learning Jupyter and SymPy for visualizarions of the same. During my high school, only Newtonian mechanics was taught, whereas in engineering college, they introduced quantum mechanics with Lagrangian/Hamiltonian formulation, skipping classical mechanics with those two. The purpose of learning is just fun.
- betimsl 3y ago
  Where are you learning this?
  - alok-g 3y ago
    Self-learning via books. I've bought a bunch. Am currently going through Susskind's Theoretical Minimum Classical Mechanics [1], also looking through No Nonsense Classical Mechanics [2].

Rust. There's certainly a lot of interesting things happening with Rust but I'm one or two problems away from deciding that Rust isn't a viable replacement for the situations where I use C.
- topspin 3y ago
  > but I'm one or two problems away Been there. You are not alone.
- dan_lannan 3y ago
  Would you mind expanding on this? I’ve had learning Rust on the back burner for a while and still default to cpp when I need to get lower level
  - kerkeslager 3y ago
    I suspect if you're looking at C++ as a viable language for the problems you're solving, you're solving quite different problems from me, so take this with a grain of salt. What I wanted from Rust was basically a strongly-typed C and more modern tooling. I'm open to more checking than that, depending on what cost it has. What I'm getting is strong typing and more modern tooling--cargo, for example, is excellent. But the borrow checker is extremely invasive, and `unsafe` doesn't actually make it less invasive. There are a number of cases where I still haven't figured out how to get the compiler to not complain about the lack of a `.clone()`. Borrow semantics are... pretty good, as it's basically enforcing a pattern I use frequently anyway, but the exceptions to that pattern are critical and working around the borrow checker causes more problems than it solves. It's possible I just don't know how to make "the Rust way" more workable, but if that's the case I am having a hard time finding how what "the Rust way" is for the things I'm trying to do. That said, I can see how Rust is a great tool for what it was originally intended for (writing a browser). That's just not what I'm doing.
    - eddd-ddde 3y ago
      Have you tried looking at zig? Also, unsafe is not meant to ease the borrow checker pains, that's like using void* everywhere in C because you don't know how to type a function pointer. Unsafe is meant for places where rust simply doesn't know better, like reading memory mapped registers.

Swift and iOS development! I've been lucky enough to spend a lot of my career being able to get my hands dirty with a bunch of different projects and at a lot of layers of the stack, but I never got deep into app development. Now I'm diving in and scratching that itch! It's also been great because I've been able to start looking beyond that to making things for the entire apple ecosystem. It's also just been so good to dive into something without any work pressure there!
- peterpans01 3y ago
  Might to share your resource? I would like to learn Swift as well. But I am lost in which roadmap to learn.
  - spikepuppet 3y ago
    Happy too! So my main resource is Hacking With Swift (https://www.hackingwithswift.com https://www.hackingwithswift.com), specifically the 100 days of SwiftUI Course. It takes you over Swift and SwiftUI. I've paired this with the official Swift site (https://www.swift.org https://www.swift.org) so I can dig into the language more, and Apple Documentation where appropriate to get used to using the tools. In terms of finding it, it was a bit of a shot in the dark. I did some poking around and this popped up the most, specifically because I was looking for iOS specific materials. I'm sure if you want to make cross platform apps there's probably a whole host of great resources!
    - mraza007 3y ago
      Thanks for sharing these resources, Would love to hear your perspective on why pick Swift over React Native as its cross platform too
      - spikepuppet 3y ago
        Happy to speak on that! I mostly wanted to dig into something I hadn't done before, with a whole new set of tools to learn. In this case, I had been super interested lately in the Apple ecosystem/platform. I'd spent some of my career in .NET/Windows land and got to see a bunch of stuff there and how it all worked, so I figured why not try out what Apple has to offer. I also felt like since I have no real intent to try and turn what I'm learning into something that makes money, I could go a little crazy/niche and dig in. This all being said, If someone asked me about making an app as something they want to release/make money off/turn into a company I'd fully be pointing them at tooling like React Native.

Longtime data engineer - web apps in vanilla HTML/CSS/JS with Node - and some fun with ncurses in C++. Copilot is helping me out a bit but I’m having fun!
- solardev 3y ago
  Hey, you're like my evil twin! Longtime web dev here who always wanted to learn more data engineering. HTML/CSS/JS is fun and creative to some degree, but kinda abstract. Data engineers get to work with real-world phenomena! What prompted the interest in web stuff?
  - milesjag 3y ago
    Hello from the other side :) 1 - I feel like more bespoke interfaces could be amazingly useful in the data world. 2 - Data engineering doesn’t really get me building creatively. 3 - Getting 3 languages to play ball (and that’s front-end only) sounds crazy challenging. Data projects are nightmares but it is good exposure to the messiness of the real world. Have you had a chance to dig into DE much yet?
    - solardev 3y ago
      All good reasons :) I never did proper "data engineering" per se, but we did have casual run-ins with geodatasets and GIS, and used them to build a home solar calculator that takes a ZIP code and estimates that area's available yearly sunlight, utility rates, electricity consumption, etc. and combine it into an estimated size for a home solar system. It was like a primitive version of Google Sunroof (https://sunroof.withgoogle.com/ https://sunroof.withgoogle.com/), which is much, much better. I too love the intersection of data and visualization/usability, turning obscure spreadsheets into useful public interfaces :) The geospatial world is just one part of that. It used to be cool, but I guess nowadays it'd probably be more about turning data into LLM-digestible training sets so that they can more directly analyze questions and answer them in plain language. Do you think traditional DE is still worth learning, with Skynet on the horizon? What's a good way to get started?
solardev 3y ago
Working my way up to calculus for the first time in my life, at nearly 40 years old. I've always hated math :( When I was a kid, they always told me math would be super useful, especially if I liked computers. Well, 20+ years of a dev career later, I still have never used anything more than basic arithmetic and rudimentary algebra (to calculate responsive component sizes). But with web dev jobs going the way of the horse-drawn wagon, I figured it was time for a career change. Hoping to get into (civil/environmental) engineering instead, but I guess that field actually does use math, lol. We'll see how it goes... In the meantime, also taking singing classes at the community college, and enjoying THAT way more. We performed at a nursing home a few weeks ago, and that brought SO much joy to the audience there, even though we're just a bunch of amateurs. It's just such a different reception than anything I've ever seen as a dev. Tech rarely inspires such joy. If I could start all over again, I wish I would've pursued music over computer stuff. Much harder life though!
- slekker 3y ago
  What resources are you using to learn calculus? I am on a similar boat
  - solardev 3y ago
    I'm taking a class at the local community college. It's OK, just some class notes and an e-textbook that I never bother to read. The pedagogy is much as I remember it, the teacher going through the problems on a whiteboard and expecting everyone to rote-memorize things. But mostly, I'm learning from ChatGPT. You can enter (or take a picture of) any problem and ask it to break it down step by step and it does that very well, and explains it better than most resources I've found. There are some OK YouTube or KhanAcademy videos too, but overall I prefer ChatGPT for its higher signal to noise ratio. At home I'll usually ask ChatGPT to explain the first one of a problem type, then try to do it again on my own and double-check it against the posted answers. For subsequent problems, I'll do it myself first (pen and paper or iPad), check it for correctness, and then ask ChatGPT for a breakdown if I screw up. I can usually tell it the mistake I made (i.e. how come I got X in step Y) and it can often correctly guess and explain where I went wrong. Some examples (keep in mind that I'm still working up to calc, so still in pre-calc right now!): * Breaking down the quadratic formula and explaining imaginary numbers: https://chat.openai.com/share/b267e954-fa0b-46ea-8fd6-11f71a346293 https://chat.openai.com/share/b267e954-fa0b-46ea-8fd6-11f71a... * Explaining properties of logs: https://chat.openai.com/share/01d79b4f-81b4-46b3-9767-be93b76a9edf https://chat.openai.com/share/01d79b4f-81b4-46b3-9767-be93b7... * e and natural logs: https://chat.openai.com/share/fbb3f957-ed6f-4c1a-af95-917d0e7be453 https://chat.openai.com/share/fbb3f957-ed6f-4c1a-af95-917d0e... * Word problems: https://chat.openai.com/share/502f7a91-9c2c-4c74-834a-5c791aa209dd https://chat.openai.com/share/502f7a91-9c2c-4c74-834a-5c791a... ----------------- Overall, I find this method of learning math (by rote memorization and parroting) very unsatisfying, and I'm unable to retain most of it in long-term memory. A few days after I learn anything I already forget how to do it. I ended up with an A in the class mostly just cramming the night before + morning of, using ChatGPT and class notes to refresh myself before the tests. But IMO it's a terrible way to learn (at least for me) and part of why I hate math. I never really learn the whys and wherefores of anything, it's just a bunch of magic shortcuts and black-box algorithms that I have to memorize and re-use without any actual understanding. It's the educational equivalent of solving every problem with someone else's function/library :( I have no idea why anything works the way it does, only that I must remember it and re-use it exactly. If anyone has a better approach to learning and retaining this stuff, I'm all ears!

  I’ve been learning Chinese for a few years. I’d recommend taking the time to learn the radicals as well, as it will help you get the feeling for what the character might mean, to the point that eventually through context and the radicals used it becomes useful to understand what it means even when you don’t actually know the character. It also makes it easier to learn characters: Yesterday I learned the character 祂 while reading about Buddhism. It means “it”, but when referring to a god, which I could infer from the context, but also from the fact that 他 means “he” (with a person radical 人）, and 她 means “her” (with a female radical 女）， and I’m familiar with the radical for god/temple which is 礻. In Chinese this also helps with “guessing” how the character should be pronounced, to an useful extent, but I don’t know if this also would apply for Japanese. Keep up the good work!

Analog synthesis. Using MiRack on my iPad mostly. Yes, that is a digital emulation of analog circuits I know but it is a great learning environment. Trying to get my head around feedback patches and self sustaining/generating patches. Saw a few videos of a guy using a Serge system to explain ideas with Cybernetics and it has really piqued my interest. I currently own a Lyra 8 synth and it is teaching me… something about FM synthesis and feedback. I also have a Vanilla synth from STG/Musonics on order and hope not be up to speed on the basics before I get it in June. I Will at some point probably get a serge system because it seems the most amenable to analog explorations at their most basic.

I read Understanding the 4 Rules of Simple Design by Corey Haines yesterday evening. It's a short book, so you can get through it in one sitting. The advice is mostly about OOP design, and how to shuffle things around and invent arbitrary constraints in order to make the code more testable. I found the advice fairly… underwhelming. I decided to implement Conway's Game of Life myself (though not with OOP) as the author asserted the advice transcends implementation languages and paradigms. My implementation isn't amazing either, but I'm not convinced by the advice in the book. Here's my implementation. https://github.com/jezen/gol https://github.com/jezen/gol

I'm a senior Android developer, and I'm learning the very basics of Jetpack Compose, and the basics of Dagger for dependency injection. All of the (very large) codebases I've worked on so far have functioned perfectly well without them, and I've always found Dagger, and now Compose, to be completely unintuitive and unnecessarily complex. But this is the way the industry has shifted, so I'm forcing myself to learn these patterns, and see if I can learn to like them. Also learning to get better on the piano, specifically improvising.

Drawing/sketching. Apropos of the other HN article on the elder mathematician who credits his success by studying the simple things until he understands them really, really well, I'm practicing drawing boxes in any/every orientation in 3D space. This includes drawing two boxes connected by a common edge - imagine a box with a lid the same size as the box itself, slightly opened. For me this is profoundly difficult to visualize. I've taken to learning the basics of Blender just so I can create these various boxes accurately to use as reference material. It's been slow going but the progress is tangible and the process is fun.

Relearning statistics with a Bayesian approach. My undergrad education was in social science research methods and I spent 4 years learning the strict frequentist approach of orthodox statistics. It made sense for highly-controlled experiments and simple dice games. But it broke down horribly when faced with any complexity and I never understood why. 25 years later, it's time to fill in the gaps. My reading list: - E.T. Janes "Probability Theory: The Logic of Science" provides the fundamental theory. - Robert McElreath "Rethinking Statistics" provides a practical application of the theory in R. - Andrew Clayton's "Bernoulli's Fallacy" is a non-technical book that provides historical context to the frequentist vs bayesian debate. I'm fairly convinced now that Bayesian approaches have more mathematical rigor than the crusty old heuristics of traditional statistics. But in terms of user-experience, doing Bayesian calculations still requires more effort on model design and more compute power. It's flexible to a fault, without a well-defined workflow. There is a strong temptation to follow the easy path - shove your data into a black box and publish if p<0.05. It's going to take a generation of (re)training and improvements to statistical software before Bayesian methods are widespread.
- ivansavz 3y ago
  +1 for the Statistical Rethinking book by McElreath. I recently took the 2024 edition of the self-paced course https://github.com/rmcelreath/stat_rethinking_2024 https://github.com/rmcelreath/stat_rethinking_2024 and the lectures on youtube are amazing. He's not just teaching stats, but how to do science! Another, more basic, book on Bayesian stats is: https://allendowney.github.io/ThinkBayes2/ https://allendowney.github.io/ThinkBayes2/ The author uses the grid approximation for everything, so there is no need to get into Stan or other framework. Myself, I'm still trying to (re)learn frequentist stuff properly (will post a separate comment about that), but the deeper I go the more convinced I am that it is total crap, and my desire to convert to the church of Bayes increases...

Statistics. I started (re)learning this subject in preparation for a new book, thinking all I had to do was review what I studied in my university days, and summarize the essential ideas, but it turns out statistics is A LOT more complicated than that. It's like a black hole that you can never get out of. There is lots of historical baggage, strong opinions, unjustified rules of thumb, etc. I've been in it for 5+ years now! As a physicist, I want to understand how things work under the hood, so I can explain to readers the underlying mechanisms and not just give formulas without explanations, and this has been very hard to do. The whole thing is well summarized by this quote from Richard McElreath "Statistics is a horrible thing." There is hope though, in recent years teaching frequentist statistics is moving toward simulation based methods, a.k.a. the modern statistics curriculum, which makes a lot of sense. Here is a blog post about that: https://minireference.com/blog/fixing-the-statistics-curriculum/ https://minireference.com/blog/fixing-the-statistics-curricu...

Nix for developer environment and building containers. I’m wondering if it’s worth it to introduce to the rest of the company. We’re pretty comfortable building/“maintaining” ~400 container images, and it’s relatively fast (~3-5 min build time if no packages are changed), but there a lot of shared dependencies between all these container images, and using nix to get actual reproducible AND minimal container images with a shared cache of Linux and language-specific packages (dotnet, node, python and R) would bring in a ton of efficiency, as well as a very consistent development environment, but I won’t force all the developers to learn nix, so the complexity should optimally be absorbed into some higher level of abstraction, like an internal CLI tool. I’m aware that the caching of dependencies can be improved, as well as creating more minimal container images, but it’s tricky with R and Python in particular, and then I figured why not just to balls-deep on nix that actually solved these issues, albeit at a cost of complexity.

  Can you recommend any resources on nix?
  - francocalvo 3y ago
    Hey! I love Nix, and I've been using it as my daily driver for more than 1 year. There is a lot of people putting a lot of energy on documenting and explaining, but the current recommendation is _suffer_. For Docker, you could start here in this HN thread [1], for NixOS and flakes there is a video series and git [2] I used at the begining which I liked. I wanted something a bit more 'complete', so if you will you can read through my nix repo [3]. I have built Portry and Go applications (that I'll push to nixpkgs at some point) and GCP images for VMs, so if you need a reference for that just ask :) [1] https://news.ycombinator.com/item?id=39720007 https://news.ycombinator.com/item?id=39720007 [2] https://github.com/MatthiasBenaets/nixos-config https://github.com/MatthiasBenaets/nixos-config [3] https://github.com/francocalvo/nixos-eris https://github.com/francocalvo/nixos-eris

I'm taking Casey Muratori's online class : https://www.computerenhance.com/p/table-of-contents https://www.computerenhance.com/p/table-of-contents The goal of the course is to give people a feeling for how fast code can be by teaching how it runs at the cpu level. I like it so far.
- miguendes 3y ago
  Has the course been useful to you in a professional setting? I mean, have you been able to apply what you’ve learned so far?
  - maximus-decimus 3y ago
    Honestly not really, but what I work on is bottlenecked by api calls and not actually DDOSing our apis. The other day I wanted to create a 10GB file with a perl one liner and it was taking over 10 minutes and doing some napkin math I figured out that should only take 4s at 1 character per clock cycle, so something is wrong (it was flushing every single character). I tried versions that flushed less and could get it to 7s by printing chunks of 1MB. That's ultimately the goal of the class, get a rough idea of what should be possible. What I really like about that class though is it really makes you realize even assembly is a high level language now. I had heard about it, but it didn't really make sense to me, but the course basically has you writing doing assembly that looks like it should be doing the same thing (e.g. same thing but with loop unrolling), and explains what's happening in the background making one version twice as fast as the other.

I'm learning PCB design, and embedded Rust to go along with it. Building a flight computer for an RC plane (I've been working on laying out and programming the computer for almost a year now -- haven't even started the airframe.) It's been very fun. I keep saying that I'm going to do a blog series about it, once I get it in an MVP stage. The state of embedded Rust is also progressing very quickly underneath me, which is nice. Writing drivers is much easier now than it was at the beginning of the project.

  Sick! I’m an embedded software engineer, but I want to grow my PCB design skills as well. Can you suggest some resources on this topic that you’re finding most valuable?
  - mlsu 3y ago
    I'm in embedded also, I started this journey at work doing board bring-up. I wrote drivers mostly, not doing any direct electrical work, but after reading the schematics I thought, "oh wow, so that's how they do schematics professionally," followed by "wait, I can do that!" Before that, I just did a few small things with Arduino. The Youtube channel Phil's Lab has a really good series [1] on PCB design focused on STM32 series chips, that is where I started. I also got a lot of good information in this thread [2] And I got feedback on one of my designs on the PrintedCircuitBoard reddit, which is very active and full of amateur and pro-am PCB designers getting feedback. You can post a schematic or layout and people will leave high quality critiques. For vendors, I have had 2 runs made with JLCPCB (with each run having flaws; some bad, and some not too bad; my board is fairly complex/ambitious so that's part of it). I have heard PCBWay is similarly cheap and good. No quality issues but I've kept traces, spacing, and components on the larger side. I'm not good at PCB design but am having a blast with it.

    When I "blitz", I'm looking for an immersive, memorable experience in my target language. Learning is merely a bi-product of that. That said, as someone with an A1 ability according to CEFR (I started learning Polish 5 months ago), my ability to follow along with a native speaking narrator, even at 2x speed, has improved exponentially. My exposure to Polish vocabulary has also exploded, and I'm familiar with many Polish words in their various grammatical forms. However, I haven't committed to long term memory as many Polish words as I'd like to. Many meanings are still fuzzy, like a word at the tip of the tongue. I think I just need to see these familiar but fuzzy words in more diverse contexts before they are nailed down. That means more blitzing.

(Edit for fixing the format) Surprised to know nobody mentions reinforcement learning here. Bought three books (in their transitional Chinese edition), whose original titles are, * Reinforcement Learning 2nd, Richard S. Sutton & Andrew G. Barto * Deep Reinforcement Learning in Action, Alexander Zai & Brandon Brown * AlphaZero 深層学習・強化学習・探索人工知能プログラミング実践入門, 布留川英一 None of them teaches you how to apply RL libraries. The first is a text book and mentions nothing about how to use frameworks at all. The last two are more practice oriented, but the examples are both too trivial, compared to a full boardgame, even the rule set is simple for humans. Since my goal is eventually to conquer a boardgame with an RL agent that is trained at home (hopefully), I would say that the 3rd book is the most helpful one. But so far my progress has been stuck for a while, because obviously I can only keep trying the hyperparameters and network architecture to find what the best ones for the game are. I kind of "went back" to the supervised learning practice in which I generated a lot of random play record, and them let the NN model at least learn some patterns out of it. Still trying...

I'm learning how to build a MMORPG. Not a complete game but a project with all the architecture in place to expand on (think Asheron's Call quality). I started programming because I wanted to work on Guild Wars 1 back in the day, but that didn't work out and I ended up as a web developer (although with some gamedev experience). I've always thought you can't make an MMO alone and so never tried. Recently a combination of health problems that scared be quite a bit and seeing other people on YouTube tackle these kinds of projects have motivated me to fulfill my childhood dream of learning the tech behind MMO games. My goal is still to work on a MMO game professionally one day, but if that never works out, at least I worked on a MMO. My own.

Finnish, mostly. I moved to Finland a few years ago and have been making slow but consistent progress along the vectors I care about ever since. I just wish language learning didn't take so much time. I've built some little tools for the task, which ended up teaching me enough about modern development that I could enter back into software as a career without too much hassle. There were no good Anki frequency list decks, so I made https://ankiweb.net/shared/info/1331009943 https://ankiweb.net/shared/info/1331009943 and later https://ankiweb.net/shared/info/1149950470 https://ankiweb.net/shared/info/1149950470 . These in turn led me to devour a book on the inner workings of SQLite and web dev, because I needed some way to scrape Tatoeba without losing my data every time. Eventually I got good enough to start reading the 'clear Finnish's news, but then I realized YLE.fi didn't seem to have an easy way for me to scrape all previous news articles, so I built https://hiandrewquinn.github.io/selkouutiset-archive/ https://hiandrewquinn.github.io/selkouutiset-archive/ as an excuse to get a little deeper into Hugo and also learn some stuff about Git modules, systemd timers, doing things on a Raspberry Pi, doing things in GCP... ... And finally today I made the first lurching version prototype of a flashcard generator for that news archive, at https://github.com/Selkouutiset-Archive/selkokortti https://github.com/Selkouutiset-Archive/selkokortti . I guess I just keep stringing the tools and interests I have together to make bigger and bigger things. Maybe that's all a career/vocation really is at the end of the day. I've also been learning a lot about QEMU and virtualization. That's mostly for work. I make software that runs on trains.

Go (the game). I wrote a clone of AlphaGo in Go (the programming language) 8 years ago. Along the way I learned to play Go. I've been using a combination of my own AI, LeelaZero and KataGo to teach myself in Go. For 8 years I've languished at the same level of play. Then I met a real human teacher who taught me Go at the end of 2023. And since then my game improved. I beat my own AI (which was intentionally trained to be impoverished in skill) for the first time in January. Learning Go is teaching me all sorts of new ideas in pedagogy and putting a dampener in any enthusiasm that involves LLMs in education.

Dart/Flutter currently, for cross platform application development. Not adverse to learning native languages or the various web frameworks, I just wanted to have one codebase across multiple platforms. I discounted the web frameworks because, as a novice, I didn't know where, or what, to begin with; I didn't want to make the wrong choice. Other than that I'm learning powershell too, mostly forced to for work, but actually it's not a bad language. On my roadmap is lua and tcl.

  This is a bit dated, but if you are interested in general electronics (rather than digital electronics), you can try https://repairfaq.org/ https://repairfaq.org/. Digital electronics is in many ways much easier, but the analog part tends to sneak in everywhere, especially when you find your digital stuff isn't working. I think it's hard to design anything new, even digitally, without at least a working knowledge of how Ohm's law, LRC circuits, transistors, diodes, op-amps, etc. work. I don't think it was this course, but I recall checking out an impressively thick book meant for US Navy technicians. The advantage there is that the assumption (unlikely college textbooks), is that you are intelligent but not college educated, and you need to know how to work on nearly anything electronic. Again, the focus is mostly the analog side. https://archive.org/details/NEETSModule01/mode/2up https://archive.org/details/NEETSModule01/mode/2up

abhgh 3y ago
I have found learning JAX to be rewarding. Of course this depends on the work you do - but if you want to occasionally code out problems which involve some kind of an optimization of a differentiable quantity (without you having to work out complex gradients), JAX is perfect.

More physics and mathematics. I am currently on Lagrangian mechanics and calculus of variations. Am also learning Jupyter and SymPy for visualizarions of the same.

> but I'm one or two problems away Been there. You are not alone.
dan_lannan 3y ago
Would you mind expanding on this? I’ve had learning Rust on the back burner for a while and still default to cpp when I need to get lower level
- kerkeslager 3y ago
  I suspect if you're looking at C++ as a viable language for the problems you're solving, you're solving quite different problems from me, so take this with a grain of salt. What I wanted from Rust was basically a strongly-typed C and more modern tooling. I'm open to more checking than that, depending on what cost it has. What I'm getting is strong typing and more modern tooling--cargo, for example, is excellent. But the borrow checker is extremely invasive, and `unsafe` doesn't actually make it less invasive. There are a number of cases where I still haven't figured out how to get the compiler to not complain about the lack of a `.clone()`. Borrow semantics are... pretty good, as it's basically enforcing a pattern I use frequently anyway, but the exceptions to that pattern are critical and working around the borrow checker causes more problems than it solves. It's possible I just don't know how to make "the Rust way" more workable, but if that's the case I am having a hard time finding how what "the Rust way" is for the things I'm trying to do. That said, I can see how Rust is a great tool for what it was originally intended for (writing a browser). That's just not what I'm doing.
  - eddd-ddde 3y ago
    Have you tried looking at zig? Also, unsafe is not meant to ease the borrow checker pains, that's like using void* everywhere in C because you don't know how to type a function pointer. Unsafe is meant for places where rust simply doesn't know better, like reading memory mapped registers.

Swift and iOS development! I've been lucky enough to spend a lot of my career being able to get my hands dirty with a bunch of different projects and at a lot of layers of the stack, but I never got deep into app development. Now I'm diving in and scratching that itch! It's also been great because I've been able to start looking beyond that to making things for the entire apple ecosystem. It's also just been so good to dive into something without any work pressure there!

- spikepuppet 3y ago
  Happy too! So my main resource is Hacking With Swift (https://www.hackingwithswift.com https://www.hackingwithswift.com), specifically the 100 days of SwiftUI Course. It takes you over Swift and SwiftUI. I've paired this with the official Swift site (https://www.swift.org https://www.swift.org) so I can dig into the language more, and Apple Documentation where appropriate to get used to using the tools. In terms of finding it, it was a bit of a shot in the dark. I did some poking around and this popped up the most, specifically because I was looking for iOS specific materials. I'm sure if you want to make cross platform apps there's probably a whole host of great resources!
  - mraza007 3y ago
    Thanks for sharing these resources, Would love to hear your perspective on why pick Swift over React Native as its cross platform too
    - spikepuppet 3y ago
      Happy to speak on that! I mostly wanted to dig into something I hadn't done before, with a whole new set of tools to learn. In this case, I had been super interested lately in the Apple ecosystem/platform. I'd spent some of my career in .NET/Windows land and got to see a bunch of stuff there and how it all worked, so I figured why not try out what Apple has to offer. I also felt like since I have no real intent to try and turn what I'm learning into something that makes money, I could go a little crazy/niche and dig in. This all being said, If someone asked me about making an app as something they want to release/make money off/turn into a company I'd fully be pointing them at tooling like React Native.

Longtime data engineer - web apps in vanilla HTML/CSS/JS with Node - and some fun with ncurses in C++. Copilot is helping me out a bit but I’m having fun!

solardev 3y ago
Hey, you're like my evil twin! Longtime web dev here who always wanted to learn more data engineering. HTML/CSS/JS is fun and creative to some degree, but kinda abstract. Data engineers get to work with real-world phenomena! What prompted the interest in web stuff?
- milesjag 3y ago
  Hello from the other side :) 1 - I feel like more bespoke interfaces could be amazingly useful in the data world. 2 - Data engineering doesn’t really get me building creatively. 3 - Getting 3 languages to play ball (and that’s front-end only) sounds crazy challenging. Data projects are nightmares but it is good exposure to the messiness of the real world. Have you had a chance to dig into DE much yet?
  - solardev 3y ago
    All good reasons :) I never did proper "data engineering" per se, but we did have casual run-ins with geodatasets and GIS, and used them to build a home solar calculator that takes a ZIP code and estimates that area's available yearly sunlight, utility rates, electricity consumption, etc. and combine it into an estimated size for a home solar system. It was like a primitive version of Google Sunroof (https://sunroof.withgoogle.com/ https://sunroof.withgoogle.com/), which is much, much better. I too love the intersection of data and visualization/usability, turning obscure spreadsheets into useful public interfaces :) The geospatial world is just one part of that. It used to be cool, but I guess nowadays it'd probably be more about turning data into LLM-digestible training sets so that they can more directly analyze questions and answer them in plain language. Do you think traditional DE is still worth learning, with Skynet on the horizon? What's a good way to get started?

solardev 3y ago

Working my way up to calculus for the first time in my life, at nearly 40 years old. I've always hated math :( When I was a kid, they always told me math would be super useful, especially if I liked computers. Well, 20+ years of a dev career later, I still have never used anything more than basic arithmetic and rudimentary algebra (to calculate responsive component sizes). But with web dev jobs going the way of the horse-drawn wagon, I figured it was time for a career change. Hoping to get into (civil/environmental) engineering instead, but I guess that field actually does use math, lol. We'll see how it goes... In the meantime, also taking singing classes at the community college, and enjoying THAT way more. We performed at a nursing home a few weeks ago, and that brought SO much joy to the audience there, even though we're just a bunch of amateurs. It's just such a different reception than anything I've ever seen as a dev. Tech rarely inspires such joy. If I could start all over again, I wish I would've pursued music over computer stuff. Much harder life though!

slekker 3y ago
What resources are you using to learn calculus? I am on a similar boat
- solardev 3y ago
  I'm taking a class at the local community college. It's OK, just some class notes and an e-textbook that I never bother to read. The pedagogy is much as I remember it, the teacher going through the problems on a whiteboard and expecting everyone to rote-memorize things. But mostly, I'm learning from ChatGPT. You can enter (or take a picture of) any problem and ask it to break it down step by step and it does that very well, and explains it better than most resources I've found. There are some OK YouTube or KhanAcademy videos too, but overall I prefer ChatGPT for its higher signal to noise ratio. At home I'll usually ask ChatGPT to explain the first one of a problem type, then try to do it again on my own and double-check it against the posted answers. For subsequent problems, I'll do it myself first (pen and paper or iPad), check it for correctness, and then ask ChatGPT for a breakdown if I screw up. I can usually tell it the mistake I made (i.e. how come I got X in step Y) and it can often correctly guess and explain where I went wrong. Some examples (keep in mind that I'm still working up to calc, so still in pre-calc right now!): * Breaking down the quadratic formula and explaining imaginary numbers: https://chat.openai.com/share/b267e954-fa0b-46ea-8fd6-11f71a346293 https://chat.openai.com/share/b267e954-fa0b-46ea-8fd6-11f71a... * Explaining properties of logs: https://chat.openai.com/share/01d79b4f-81b4-46b3-9767-be93b76a9edf https://chat.openai.com/share/01d79b4f-81b4-46b3-9767-be93b7... * e and natural logs: https://chat.openai.com/share/fbb3f957-ed6f-4c1a-af95-917d0e7be453 https://chat.openai.com/share/fbb3f957-ed6f-4c1a-af95-917d0e... * Word problems: https://chat.openai.com/share/502f7a91-9c2c-4c74-834a-5c791aa209dd https://chat.openai.com/share/502f7a91-9c2c-4c74-834a-5c791a... ----------------- Overall, I find this method of learning math (by rote memorization and parroting) very unsatisfying, and I'm unable to retain most of it in long-term memory. A few days after I learn anything I already forget how to do it. I ended up with an A in the class mostly just cramming the night before + morning of, using ChatGPT and class notes to refresh myself before the tests. But IMO it's a terrible way to learn (at least for me) and part of why I hate math. I never really learn the whys and wherefores of anything, it's just a bunch of magic shortcuts and black-box algorithms that I have to memorize and re-use without any actual understanding. It's the educational equivalent of solving every problem with someone else's function/library :( I have no idea why anything works the way it does, only that I must remember it and re-use it exactly. If anyone has a better approach to learning and retaining this stuff, I'm all ears!

I’ve been learning Chinese for a few years. I’d recommend taking the time to learn the radicals as well, as it will help you get the feeling for what the character might mean, to the point that eventually through context and the radicals used it becomes useful to understand what it means even when you don’t actually know the character. It also makes it easier to learn characters: Yesterday I learned the character 祂 while reading about Buddhism. It means “it”, but when referring to a god, which I could infer from the context, but also from the fact that 他 means “he” (with a person radical 人）, and 她 means “her” (with a female radical 女）， and I’m familiar with the radical for god/temple which is 礻. In Chinese this also helps with “guessing” how the character should be pronounced, to an useful extent, but I don’t know if this also would apply for Japanese. Keep up the good work!

Analog synthesis. Using MiRack on my iPad mostly. Yes, that is a digital emulation of analog circuits I know but it is a great learning environment. Trying to get my head around feedback patches and self sustaining/generating patches. Saw a few videos of a guy using a Serge system to explain ideas with Cybernetics and it has really piqued my interest. I currently own a Lyra 8 synth and it is teaching me… something about FM synthesis and feedback. I also have a Vanilla synth from STG/Musonics on order and hope not be up to speed on the basics before I get it in June. I Will at some point probably get a serge system because it seems the most amenable to analog explorations at their most basic.

I read Understanding the 4 Rules of Simple Design by Corey Haines yesterday evening. It's a short book, so you can get through it in one sitting. The advice is mostly about OOP design, and how to shuffle things around and invent arbitrary constraints in order to make the code more testable. I found the advice fairly… underwhelming. I decided to implement Conway's Game of Life myself (though not with OOP) as the author asserted the advice transcends implementation languages and paradigms. My implementation isn't amazing either, but I'm not convinced by the advice in the book. Here's my implementation. https://github.com/jezen/gol https://github.com/jezen/gol

But this is the way the industry has shifted, so I'm forcing myself to learn these patterns, and see if I can learn to like them. Also learning to get better on the piano, specifically improvising.

Drawing/sketching. Apropos of the other HN article on the elder mathematician who credits his success by studying the simple things until he understands them really, really well, I'm practicing drawing boxes in any/every orientation in 3D space. This includes drawing two boxes connected by a common edge - imagine a box with a lid the same size as the box itself, slightly opened. For me this is profoundly difficult to visualize. I've taken to learning the basics of Blender just so I can create these various boxes accurately to use as reference material. It's been slow going but the progress is tangible and the process is fun.

Relearning statistics with a Bayesian approach. My undergrad education was in social science research methods and I spent 4 years learning the strict frequentist approach of orthodox statistics. It made sense for highly-controlled experiments and simple dice games. But it broke down horribly when faced with any complexity and I never understood why. 25 years later, it's time to fill in the gaps. My reading list: - E.T. Janes "Probability Theory: The Logic of Science" provides the fundamental theory. - Robert McElreath "Rethinking Statistics" provides a practical application of the theory in R. - Andrew Clayton's "Bernoulli's Fallacy" is a non-technical book that provides historical context to the frequentist vs bayesian debate. I'm fairly convinced now that Bayesian approaches have more mathematical rigor than the crusty old heuristics of traditional statistics. But in terms of user-experience, doing Bayesian calculations still requires more effort on model design and more compute power. It's flexible to a fault, without a well-defined workflow. There is a strong temptation to follow the easy path - shove your data into a black box and publish if p<0.05. It's going to take a generation of (re)training and improvements to statistical software before Bayesian methods are widespread.

ivansavz 3y ago
+1 for the Statistical Rethinking book by McElreath. I recently took the 2024 edition of the self-paced course https://github.com/rmcelreath/stat_rethinking_2024 https://github.com/rmcelreath/stat_rethinking_2024 and the lectures on youtube are amazing. He's not just teaching stats, but how to do science! Another, more basic, book on Bayesian stats is: https://allendowney.github.io/ThinkBayes2/ https://allendowney.github.io/ThinkBayes2/ The author uses the grid approximation for everything, so there is no need to get into Stan or other framework. Myself, I'm still trying to (re)learn frequentist stuff properly (will post a separate comment about that), but the deeper I go the more convinced I am that it is total crap, and my desire to convert to the church of Bayes increases...

ivansavz 3y ago
What are you using to review/relearn basic math? I'm asking because this is the space I'm working in, so I wonder what "products" people are hiring to do this "job." PS: Check out this concept map that shows the high school math concepts and topics that you can use as a "progress bar" for what there is to review: https://minireference.com/static/conceptmaps/math_concepts.pdf https://minireference.com/static/conceptmaps/math_concepts.p...

  Tbh I don't have any specific path how to do it right now as I started doing this just recently. Currently it's something like: "oh, I don't remember how to do this, I'll check it on wikipedia/yt/<some random page found in google>". But this way I can't relearn things that I simply forgot that it exist. Thanks for the link!

Statistics. I started (re)learning this subject in preparation for a new book, thinking all I had to do was review what I studied in my university days, and summarize the essential ideas, but it turns out statistics is A LOT more complicated than that. It's like a black hole that you can never get out of. There is lots of historical baggage, strong opinions, unjustified rules of thumb, etc. I've been in it for 5+ years now! As a physicist, I want to understand how things work under the hood, so I can explain to readers the underlying mechanisms and not just give formulas without explanations, and this has been very hard to do. The whole thing is well summarized by this quote from Richard McElreath "Statistics is a horrible thing." There is hope though, in recent years teaching frequentist statistics is moving toward simulation based methods, a.k.a. the modern statistics curriculum, which makes a lot of sense. Here is a blog post about that: https://minireference.com/blog/fixing-the-statistics-curriculum/ https://minireference.com/blog/fixing-the-statistics-curricu...

Nix for developer environment and building containers. I’m wondering if it’s worth it to introduce to the rest of the company. We’re pretty comfortable building/“maintaining” ~400 container images, and it’s relatively fast (~3-5 min build time if no packages are changed), but there a lot of shared dependencies between all these container images, and using nix to get actual reproducible AND minimal container images with a shared cache of Linux and language-specific packages (dotnet, node, python and R) would bring in a ton of efficiency, as well as a very consistent development environment, but I won’t force all the developers to learn nix, so the complexity should optimally be absorbed into some higher level of abstraction, like an internal CLI tool. I’m aware that the caching of dependencies can be improved, as well as creating more minimal container images, but it’s tricky with R and Python in particular, and then I figured why not just to balls-deep on nix that actually solved these issues, albeit at a cost of complexity.

Can you recommend any resources on nix?
- francocalvo 3y ago
  Hey! I love Nix, and I've been using it as my daily driver for more than 1 year. There is a lot of people putting a lot of energy on documenting and explaining, but the current recommendation is _suffer_. For Docker, you could start here in this HN thread [1], for NixOS and flakes there is a video series and git [2] I used at the begining which I liked. I wanted something a bit more 'complete', so if you will you can read through my nix repo [3]. I have built Portry and Go applications (that I'll push to nixpkgs at some point) and GCP images for VMs, so if you need a reference for that just ask :) [1] https://news.ycombinator.com/item?id=39720007 https://news.ycombinator.com/item?id=39720007 [2] https://github.com/MatthiasBenaets/nixos-config https://github.com/MatthiasBenaets/nixos-config [3] https://github.com/francocalvo/nixos-eris https://github.com/francocalvo/nixos-eris

I'm taking Casey Muratori's online class : https://www.computerenhance.com/p/table-of-contents https://www.computerenhance.com/p/table-of-contents The goal of the course is to give people a feeling for how fast code can be by teaching how it runs at the cpu level. I like it so far.

miguendes 3y ago
Has the course been useful to you in a professional setting? I mean, have you been able to apply what you’ve learned so far?
- maximus-decimus 3y ago
  Honestly not really, but what I work on is bottlenecked by api calls and not actually DDOSing our apis. The other day I wanted to create a 10GB file with a perl one liner and it was taking over 10 minutes and doing some napkin math I figured out that should only take 4s at 1 character per clock cycle, so something is wrong (it was flushing every single character). I tried versions that flushed less and could get it to 7s by printing chunks of 1MB. That's ultimately the goal of the class, get a rough idea of what should be possible. What I really like about that class though is it really makes you realize even assembly is a high level language now. I had heard about it, but it didn't really make sense to me, but the course basically has you writing doing assembly that looks like it should be doing the same thing (e.g. same thing but with loop unrolling), and explains what's happening in the background making one version twice as fast as the other.

I'm learning PCB design, and embedded Rust to go along with it. Building a flight computer for an RC plane (I've been working on laying out and programming the computer for almost a year now -- haven't even started the airframe.) It's been very fun. I keep saying that I'm going to do a blog series about it, once I get it in an MVP stage. The state of embedded Rust is also progressing very quickly underneath me, which is nice. Writing drivers is much easier now than it was at the beginning of the project.

xMichael24 3y ago
Sick! I’m an embedded software engineer, but I want to grow my PCB design skills as well. Can you suggest some resources on this topic that you’re finding most valuable?
- mlsu 3y ago
  I'm in embedded also, I started this journey at work doing board bring-up. I wrote drivers mostly, not doing any direct electrical work, but after reading the schematics I thought, "oh wow, so that's how they do schematics professionally," followed by "wait, I can do that!" Before that, I just did a few small things with Arduino. The Youtube channel Phil's Lab has a really good series [1] on PCB design focused on STM32 series chips, that is where I started. I also got a lot of good information in this thread [2] And I got feedback on one of my designs on the PrintedCircuitBoard reddit, which is very active and full of amateur and pro-am PCB designers getting feedback. You can post a schematic or layout and people will leave high quality critiques. For vendors, I have had 2 runs made with JLCPCB (with each run having flaws; some bad, and some not too bad; my board is fairly complex/ambitious so that's part of it). I have heard PCBWay is similarly cheap and good. No quality issues but I've kept traces, spacing, and components on the larger side. I'm not good at PCB design but am having a blast with it.

  When I "blitz", I'm looking for an immersive, memorable experience in my target language. Learning is merely a bi-product of that. That said, as someone with an A1 ability according to CEFR (I started learning Polish 5 months ago), my ability to follow along with a native speaking narrator, even at 2x speed, has improved exponentially. My exposure to Polish vocabulary has also exploded, and I'm familiar with many Polish words in their various grammatical forms. However, I haven't committed to long term memory as many Polish words as I'd like to. Many meanings are still fuzzy, like a word at the tip of the tongue. I think I just need to see these familiar but fuzzy words in more diverse contexts before they are nailed down. That means more blitzing.

(Edit for fixing the format) Surprised to know nobody mentions reinforcement learning here. Bought three books (in their transitional Chinese edition), whose original titles are, * Reinforcement Learning 2nd, Richard S. Sutton & Andrew G. Barto * Deep Reinforcement Learning in Action, Alexander Zai & Brandon Brown * AlphaZero 深層学習・強化学習・探索人工知能プログラミング実践入門, 布留川英一 None of them teaches you how to apply RL libraries. The first is a text book and mentions nothing about how to use frameworks at all. The last two are more practice oriented, but the examples are both too trivial, compared to a full boardgame, even the rule set is simple for humans. Since my goal is eventually to conquer a boardgame with an RL agent that is trained at home (hopefully), I would say that the 3rd book is the most helpful one. But so far my progress has been stuck for a while, because obviously I can only keep trying the hyperparameters and network architecture to find what the best ones for the game are. I kind of "went back" to the supervised learning practice in which I generated a lot of random play record, and them let the NN model at least learn some patterns out of it. Still trying...

I'm learning how to build a MMORPG. Not a complete game but a project with all the architecture in place to expand on (think Asheron's Call quality). I started programming because I wanted to work on Guild Wars 1 back in the day, but that didn't work out and I ended up as a web developer (although with some gamedev experience). I've always thought you can't make an MMO alone and so never tried. Recently a combination of health problems that scared be quite a bit and seeing other people on YouTube tackle these kinds of projects have motivated me to fulfill my childhood dream of learning the tech behind MMO games. My goal is still to work on a MMO game professionally one day, but if that never works out, at least I worked on a MMO. My own.

Finnish, mostly. I moved to Finland a few years ago and have been making slow but consistent progress along the vectors I care about ever since. I just wish language learning didn't take so much time. I've built some little tools for the task, which ended up teaching me enough about modern development that I could enter back into software as a career without too much hassle. There were no good Anki frequency list decks, so I made https://ankiweb.net/shared/info/1331009943 https://ankiweb.net/shared/info/1331009943 and later https://ankiweb.net/shared/info/1149950470 https://ankiweb.net/shared/info/1149950470 . These in turn led me to devour a book on the inner workings of SQLite and web dev, because I needed some way to scrape Tatoeba without losing my data every time. Eventually I got good enough to start reading the 'clear Finnish's news, but then I realized YLE.fi didn't seem to have an easy way for me to scrape all previous news articles, so I built https://hiandrewquinn.github.io/selkouutiset-archive/ https://hiandrewquinn.github.io/selkouutiset-archive/ as an excuse to get a little deeper into Hugo and also learn some stuff about Git modules, systemd timers, doing things on a Raspberry Pi, doing things in GCP... ... And finally today I made the first lurching version prototype of a flashcard generator for that news archive, at https://github.com/Selkouutiset-Archive/selkokortti https://github.com/Selkouutiset-Archive/selkokortti . I guess I just keep stringing the tools and interests I have together to make bigger and bigger things. Maybe that's all a career/vocation really is at the end of the day. I've also been learning a lot about QEMU and virtualization. That's mostly for work. I make software that runs on trains.

A bit more high level but I plan to dive back into more specific areas afterwards and read through the just recently updated version of Difficult Conversations.

First-time founder here! I have always worked as a developer and have been building products for the past 6 years. But as a founder, you need to know GTM and growth for your product! Initially, we used to think that we could outsource, but we were so wrong! :D Hence, now learning it on our own. Happy to take help and suggestions, or if you are up for the discussion around growth, GTM and marketing.

Congrats on embracing the marketing learning curve! I'm curious, what has been the most surprising learning you've had in marketing your startup?

Programming a 128x128 OLED screen using a microcontroller over an I2C communication. Low-level programming of any mildly-complicated hardware device using microcontrollers is a PITA.

Docker. It would be helpful for my job in certain situations and I also find it interesting. I also recently started getting back into HTML/CSS.

I'm learning to be contend with what I have and oh God that's impossible.

Go (the game). I wrote a clone of AlphaGo in Go (the programming language) 8 years ago. Along the way I learned to play Go. I've been using a combination of my own AI, LeelaZero and KataGo to teach myself in Go. For 8 years I've languished at the same level of play. Then I met a real human teacher who taught me Go at the end of 2023. And since then my game improved. I beat my own AI (which was intentionally trained to be impoverished in skill) for the first time in January. Learning Go is teaching me all sorts of new ideas in pedagogy and putting a dampener in any enthusiasm that involves LLMs in education.

I've been learning Godot (4.2), and leveraging chatgpt to try and elicit as much of my idea in generated code as possible. After about 4 months of work, I'm closing in on a working v1, hoping to do an open beta in the next few months. https://old.reddit.com/r/boomballs/ https://old.reddit.com/r/boomballs/

I'm a threat intel analyst and recently started self-learning how to improve my storytelling skills, which is generally lacking in cybersecurity. I've refined my writing skills over the years, starting with Medium, LinkedIn newsletters, and now Substack: https://shorturl.at/jHKLQ https://shorturl.at/jHKLQ

I am working my way through "The Seasoned Schemer". Maybe I will go for "The Reasoned Schemer" next. Or "The Little Learner". Great series of books.
