Products that do what Learn You Galois Fields for Great Good does

Hi All, I've been writing a series on Galois Fields / Finite Fields from a computer programmer's perspective. It's essentially the guide that I wanted when I first learned the subject. I imagine it as a guide that could gently onboard anyone that is interested in the subject. I don't assume too much mathematical background beyond high-school level algebra. However, in some applications (for example: Reed-Solomon), familiarity with Linear Algebra is required. All code is written in a Literate Programming style. Code is written as reference implementations and I try hard to make…

    Hi everyone! I just released the Practical Python Projects book! (https://practicalpython.yasoob.me) I am happy to announce the first version as a release candidate. I have poured a lot of love into writing this book and would love to hear what you guys think. (A limited 100% off and discount coupons at the end) This is not a pure beginner book. The book does assume some background Python knowledge. You need to know the basics like methods, functions, classes, and such. If I use something that is not typically covered in beginner Python books, I will explain it before I use it.…

    In past few weeks, I wrote several chapters to learn Scheme, a programming language of the Lisp dialect. The writing is not final as many chapters are missing. I wrote this because I wanted to improve my Scheme knowledge and increase the (low) number of Scheme literature. The writing is inspired by Calculus Made Easy, which I learned about here on HN. This is why I'm sharing it here. But keep in mind that my writing style is not as good as that in the above-mentioned inspiration. Feedback is very much appreciated.

    Hi! I am doing a learning project, attempting to build an imperative language (and interpreter). The end product will be useless for others, I just want to learn and better understand how to build imperative languages. :) If someone else shares this interest and want to give some good hints on good resources I would be grateful. Currently I am looking at an awesome text by Bob Nystrom. All suggestions and tips on resources are most welcome. I am very much a beginner in this, but I find this topic very fascinating. Mail me or post links here! Cheers! You can try a beta version Online at…

    I have had a few conversations in the past year with non-technical folks (traditional finance types, consultants) who asked for a simple explainer on how GPTs work. These people generally have the horsepower to grasp new concepts quickly but don't necessarily have the math background to dig in super deeply and want a stronger framework than "they predict words". I had generally been pointing them to Karpathy, Illustrated Transformer, and other youtube content but I figured something more hands on without the math requirement might be better at explaining questions like "why matrix…

    Hi HN! I kept hearing about Lisp and why it was special but didn't have a great place to start. I wanted something self-contained that helped me develop intuition rather than fluency. My hope is this is helpful for casual programmers, professionals from other fields who interact with code, or engineers who haven't had much exposure to interpreters or compilers. Hope this helps anyone else who's curious about getting a sense of Lisp and what makes it special with a limited time investment! Feedback or other cool Lisp things welcome :)

    Hi guys, Two days ago I published the fourth post in the series and thought it would now be a good time to look for additional feedback here on Hacker News. The aim of the series (as mentioned in the first post) is to inspire more people to start using Qt. My ambition is to answer the following questions "what is the gist of Qt?"; "what is the 20% that you need to know to develop 80% of the application?"; "what are the perhaps unknown unknowns?". In other words, I'm just covering basics: enough to understand the concepts and where to find additional information should you need it. Do you…

    Hey HN, I wrote a short book about the fundamental aspects of Clojure. The target audience is programmers with at least minimal experience who want to learn how to express solutions in Clojure (and perhaps in LISP, generally). If the price is a bit too steep for you, send me an email (address in bio), and I'll provide a discount coupon. If you can't afford it all, and believe the material may help you for studying or interview preparations, I can send you a free copy.

    I’m 15 and self-taught. I'm learning ML from scratch because I want to really understand how things work. I’m not into frameworks. I prefer math, logic, and C++. I implemented a basic MLP that supports different activation and loss functions. It was trained via mini-batch gradient descent. I wrote it from scratch, using no external libraries except Eigen (for linear algebra). I learned how a Neural Network learns (all the math) -- how the forward pass works, and how learning via backpropagation works. How to convert all that math into code. I’ll write a blog soon explaining how MLPs work in…

    Hi Y'all, for those interested in trading using quantitative finance ideas, I'm open sourcing the software I made in the past 10+ years along with a series of tutorials on YouTube which gradually introduce the concepts. It's work in progress, for now I covered the foundations (stock price movements, option valuation, the arbitrage idea and the replication technique). Next I'll introduce how to import historical market data for stocks and options along with where you can buy it for a reasonable price (you can't find free historical options data) and some basic cleanup techniques because it…

    I have been interested in neural nets since the 90's. I've done quite a bit of reading, but never gotten around to writing code. I used Gemini in place of Wikipedia to fill in the gaps of my knowledge. The coolest part of this was learning about dual numbers. You can see in early commits that I did not yet know about auto-diff; I was thinking I'd have to integrate a CAS library or something. Now, I'm off to play with TensorFlow.

    I wanted to learn more about RAG implementations, so I built something to solve the constant digging through manuals whenever we play a game. It's fairly simplistic, but actually has worked pretty well for some of these conflicts. Everythings Open Source on GitHub if you're curious (or have ideas), and I'd love to hear feedback from fellow boardgamers!

    hey folks! My book Real-World Cryptography was just released and is now shipping. I've been working on this thing for the last two years and a half, and the goal was to give a good overview of everything that can be classified as "real-world" about crypto. You'll find all the basics in the first half of the book, and the second half contains chapters on TLS, noise, PAKEs, post-quantum cryptography, zero-knowledge proofs, MPC, cryptocurrencies, FHE, etc. So it's a good pick if you're learning, but also if you've been in the field for a while and want an intro to some subfield you're…

    Hi everyone, I’m a student with a strong interest in computer science and complexity theory. Recently, I worked on a manuscript attempting to prove that P ≠ NP. I know how this sounds — it’s one of the hardest and most debated problems in CS, and many have tried and failed. I don’t claim to have the final answer, but I believe the approach I used might at least offer some fresh perspective or provoke useful critique. The idea involves geometric separation between deterministic and nondeterministic computation, using high-dimensional lattice constructions and some physics-inspired intuition.…

    Hi there! I'm building Diagrammatic, a simple and free online tool with the ambition to become a community for diagrams-as-code enthusiasts. Currently, it supports Mermaid, PlantUML, Dot (Graphviz), Vega-Lite, and Typogram, but I'm looking to add more languages. Please let me know if there's a particular one you use. I'd appreciate any kind of constructive feedback as well. Thanks in advance!

    Hey HN, as a former data analyst, I’ve been tooling around trying to get agents to do my old job. The result is this system that gets you maybe 80% of the way there. I think this is a good data point for what the current frontier models are capable of and where they are still lacking (in this case — hypothesis generation and general data intuition). Some initial learnings: - Generating web app-based reports goes much better if there are explicit templates/pre-defined components for the model to use. - Claude can “heal” broken charts if you give it access to chart images and run a…

    If AI got lucky or not, AI is surely going to assist in solving serious math problems. If you want to spend your resources/weekends contributing, this repository is full of math problems where you can add your thoughts (or proofs - for you Good Will Hunting type people) for others to build on it and we all together can try to change the world of math. I have already extended the research with manual proof of Jacobian Conjecture that was posted on Twitter (with attribution).

    Hello! I love anki and have been using it for years to learn mandarin, but I'm lazy and always struggled to get over the "motivation hump" to sit down and create a deck. Recently I've been consuming a lot of AI content from youtube, and spent 3 days creating a deck for Andrej Karpathy's "Deep Dive into LLMs" video. This is impractical - so I built a little youtube to anki converter @ asimpleai.com It's rough around the edges... but I would like it to eventually become something useful to community. Feedback and suggestions are welcome! peace

    Hi everyone! We (Christopher and Govind) have started a video tutorial series of 20-25 minute long episodes on how to make various common computer science data structures, such as vectors, linked lists, hashmaps, and so on. So far, we’ve done a two-part series on how to implement vectors. Links to parts one and two of the Vectors series: https://www.youtube.com/watch?v=vr0KzD_Owxc https://www.youtube.com/watch?v=t3kgbdhUIxU (Sorry about the low quality of the video in the first link, we accidentally recorded in 720p. The second part is in 1080p!) Although so far…
