“teaching engineers to build production AI systems” in bio
Alexey Grigorev@Al_Grigor

Claude Code wiped our production database with a Terraform command. It took down the DataTalksClub course platform and 2.5 years of submissions: homework, projects, and leaderboards. Automated snapshots were gone too. In the newsletter, I wrote the full timeline + what I changed so this doesn't happen again. If you use Terraform (or let agents touch infra), this is a good story for you to read. alexeyondata.substack.com/p/how-i-droppe…

Haskell をホスト言語に CIC（CoC + 帰納型 + 累積的宇宙）を Locally nameless + Normalization by Evaluation + 双方向型検査 で実装した定理証明器を自作、その上で等式型や自然数の定義から加法の交換法則の証明まで実装した🧑‍💻 帰納型は定数を解決する機構を用意して後から追加できるようにしてる

@__tosh So frustrating, following other providers doing the same too.. Anyway, at least we can watch videos of cats piloting planes and stuff

@awnihannun I was having fun recently with taking advantage of lisp with llms for similar reasons, i didn't tightly couple it but it still felt way more intuitive than current paradigms - glensargent.com/living-servers

Looking at the recursive LM (RLM) paper this morning. It's actually quite simple and nice idea: give the LM a REPL. The paper is marketed as solving long-context. But I think the key nugget is to give the LM a REPL. The REPL is useful because: - Execute code in it -> let's you compute things - Has a function to query a sub LLM (basically sub-agents) - Can hold arbitrary state (like new variables etc). Also I understood the paper much better by reading the system prompt than the actual paper 😅

Ive been working on something special ready for the 2026 #f1 season & #F1Testing , it's not unique as it's a timing platform but it's free and I am working on some cool features not available on others. Trying to get a good level of polish - check it out deltasync.pro

@James_paul_dev @ChShersh @_trish_xD theres simpler languages that can do the maths better, people write python cause people write python, not because its the best at anything

@ChShersh @_trish_xD I love c++ bt you should understand why many people choose python over c++ for ai/ml. The reason is ai/ml requires more maths, stats and probly knowlege and they don't care about performance, they want simple programming language so that can try different experiment quickly.

9 months ago, I moved from a decade of using Haskell and OCaml to C++. I used to work on REST API microservices and CLI tools. Now I write realtime market data handlers. I’m still not used to the new job. It feels like a completely different industry to me.
Dmitrii Kovanikov@ChShersh

Huge announcement. I'm leaving Bloomberg as an OCaml Engineer. And.. I'm joining Bloomberg as a C++ Engineer. After using Functional Programming primarily for the last 10 years, it's time for me to switch gears. I moved to another team internally. I'll be working on low-latency real-time market data in C++. It's a big change for me. But I'm excited about a new challenge! AMA

Our engineer flat-out refuses to use AI IDEs like Cursor or Claude Code. He will use LLMs to look things up or proofread, but he will not let them touch the actual code. That is basically turtle speed compared to using an AI IDE, so yeah, we ship slower. But at least I can sleep at night knowing the codebase will not slowly turn into auto-generated spaghetti that nobody really understands and that becomes expensive technical debt later.
Ishaan Sehgal@ishaansehgal

Talked with a senior engineer who's been coding for 15 years. Loved the craft, mentored juniors, built systems from scratch. Just quit. Here's what broke him: His entire job became prompting AI and reviewing generated code. The actual engineering, the part he loved, disappeared.

@Pirat_Nation >Requiring in-game add-ons to be purchased only through Steam You mean to tell me that you can only purchase DLC from the seller of the original game so they know where to place the files!?!?!? WOW!

Valve faces a £656 million UK class-action lawsuit over Steam pricing and commissions. Brought by digital rights campaigner Vicki Shotbolt on behalf of up to 14 million UK Steam customers since June 2018, the claim alleges Valve abused its dominant market position by: >Forcing publishers to avoid cheaper/earlier sales on rival stores >Requiring in-game add-ons to be purchased only through Steam >Charging up to 30% commissions, described as excessive and leading to higher consumer prices The tribunal granted an opt-out collective order eligible UK residents are automatically included unless they opt out. Estimated damages: roughly £22–£44 per person (higher in Scotland). Valve has not commented publicly since the ruling.

Either use nano for minor edits or VS Code for major changes. The same logic applies to operating systems: Use a polished OS like macOS or Windows, or choose Ubuntu, Pop!_OS, or Linux Mint if you want something free, solid, with good hardware support and sane defaults. I've been a distro hopper myself. The "I use Arch, btw" flex is temporary. After a certain point in life or career, most devs quietly switch to "I use whatever lets me ship fastest with the least mental overhead."

@EnergyThen @tritlo they’re unbelievably unimpressive, but tbh all those ruby shops are the same (shoutout HEY, which have something like 1 cpu per mau) - 3.18 million cpus for 320m requests per minute, are you mad!?!?!? sounds like a complete disaster, i actually can not understand it

@glensarge @tritlo Precisely, not just anything will scale even given infinite compute. But Shopify is probably the least interesting example anyone can think of. Scaling Shopify to millions of tenants is the simplest distributed architecture challenge there is, solved by textbook sharding.

we spent 20 years of effort on this it’s “not really a problem” because millennia of man hour engineering effort made it go away
Vlad Mihalcea@vlad_mihalcea

Scaling is not really a problem for SQL databases. Shopify is running its distributed monolith on MySQL 8 and can scale to over 50 million queries per second. With every Black Friday campaign, they raise the bar even higher. Facebook uses MySQL with MyRocks. You can find their MySQL fork on GitHub. So, if SQL works fine for the largest software platforms in the world, it's surely going to work just fine for the vast majority of your projects.

“Programming is no longer fun” is where the issue is I think. It should never have been “fun” For “fun” please play a game or step outside and kick a ball around. Building software is about making someone else’s life easier through automation. It’s a pursuit, not leisure.
Dmitrii Kovanikov@ChShersh

I vibe-coded my first app today using Claude Code. 1 hour to do what would have taken me a whole weekend before. Programming is no longer fun. But building is more fun than ever.
