Show HN: Learn You Galois Fields for Great Good
3 by xorvoid | 0 comments on Hacker News.
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 implementations understandable. Currently I've completed the following sections: 01: Group Theory 02: Field Theory 03: Implementing GF(p) 04: Polynomial Arithmetic 05: Polynomial Fields GF(p^k) 06: Implementing GF(p^k) 07: Implementing Binary Fields GF(2^k) 08: Cyclic Redundancy Check (CRC) 09: Linear Algebra over Fields Future sections are planned: Reed-Solomon Erasure Coding AES (Rijndael) Encryption Rabin Fingerprinting Extended Euclidean Algorithm Log and Invlog Tables Elliptic Curves Bit-matrix Representations of GF(2^k) Cauchy Reed-Solomon XOR Codes Fast Multiplication with FFTs Vectorization Implementation Techniques I hope this series is helpful to people out there. Happy to answer any questions and would love to incorporate feedback.

Multiple unsubscribe-less emails saying e.g. "Thanks for visiting one of our Microsoft Rewards pages. You've now unlocked the full potential of Microsoft Rewards". That's the full potential to be spammed, it seems.

Hi, I'm researching for my upcoming hackathon. In a short term, which MCP server do you wish existed but it’s not? The hackathon aims to develop an AI MCP server, and I would be happy to get some ideas. Like Cursor and Figma communication or something. Thank you!

Show HN: Kubetail – Real-time log search for Kubernetes
13 by andres | 5 comments on Hacker News.
Hi Everyone! Kubetail is a general-purpose logging dashboard for Kubernetes, optimized for tailing logs across multi-container workloads in real-time. With Kubetail, you can view logs from all the containers in a workload (e.g. Deployment or DaemonSet) merged into a single chronological timeline, delivered to your browser or terminal. I launched Kubetail on HN last year and at that time the top request was to add search. Now I'm happy to say we finally have search available in our latest official release (cli/v0.4.3, helm/v0.10.1). You can check it out in action here: https://ift.tt/FkIPz0d Kubetail normally fetches logs using the Kubernetes API, which does not have search built-in. To enable search, click the “Install” button in the GUI or run `kubetail cluster install` in the CLI to deploy a DaemonSet that places a Kubetail agent on every node. Each agent runs a custom Rust binary powered by ripgrep; it scans the node’s log files and streams only matching lines to your browser or terminal. You can think of a Kubetail search as "remote grep" for your Kubernetes logs. Now you don’t need to download an entire log file just to grep it locally. Since last year we've also added some other neat features that users find helpful. In particular, we built a simple CLI tool that starts the web dashboard on your desktop: # Install brew install kubetail # Run kubetail serve We also added a powerful logs sub-command to the CLI that you can use to follow container logs or even fetch all the records in a given time window to analyze them in more detail locally (quick-start): # Follow example $ kubetail logs deployments/web \ --with-ts \ --with-pod \ --follow # Fetch example $ kubetail logs deployments/web \ --since 2025-04-20T00:00:00Z \ --until 2025-04-21T00:00:00Z \ --all > logs.txt We’ve added a lot more features since last year but these are the ones I wanted to highlight. I hope you like what we're doing with Kubetail! Your feedback is very valuable so please let us know what you think in the comments here or in our Discord chat. Andres

fun little side project using gemini 2.5 pro. summarizes the top 30 HN stories and their comment threads. kinda nice when there's a huge thread to read the tl;dr. cron job updates everything once an hour right now. feel free to pick it apart!

Ask HN: 3rd Week at FAANG and feeling imposter syndrome
6 by HowDoesSound | 4 comments on Hacker News.
A bit about my, I'm early 30s frontend engineer w/ no degree who started working at FAANG. Before that I spent about 12 years working at agencies doing web dev, Drupal, wordpress, etc. By week 2 at FAANG I'd gotten through the onboarding, figured out how to get my app running behind all the business security and policies, and started trying to work on a simple frontend React bugfix. I'm struggling to make heads and tails of everything going up. I understand what processes exist and why at a theoretical level, but all the outdated documentation, random commands to input and feature flags to setup, etc. is literally driving me in circles. Also my team is VERY busy, so I've had to figure out everything on my own. I have the app working, but I cannot understand beginning to end how the frontend app works. Also I'm feeling a strong sense of imposter syndrome. I'm the oldest engineer on my team, surrounded by a bunch of fresh 20 year olds 3 years out of college who's first job is FAANG. There's an air of non-egotistical elitism I just can't put my finger on, but as someone who dropped out of college so they could earn money and lessen the burden of their immigrant parents, I just feel like I really really don't belong. Right now at work I've taken on a ticket that should be simple, but I just cannot understand why it's not working in the massive ecosystem and integrations that exists for this app. Also on a sidenote, I'm a bit disappointed in the sense that I expected more from FAANG. The quality of the apps I'm seeing seems vastly technically overengineered, almost like 100 different hero engineers added their own "tricks" just to seem clever, make a name for themself, make everyone else's life harder, and then pat themselves on the back while writing extensive documentation about why their little chrome extension or alternative way of doing things solves X,Y,Z (while completely ignoring how convoluted and burdensome they've now made something that, while technically inconvenient, was utterly simple to understand prior). Anyway, rant over. Anyone felt the same way starting at FAANG? Not sure if I'm gonna stick around.
