@Cloudflare my old raspberry pi 2 from 2015 is still chugging along, outlasted three laptops. guess reliability isnt a feature you pay for anymore.

Home lab enthusiasts assemble. What is the oldest piece of hardware currently running in your home network setup? #CloudflareChat

@ujjwalscript next they'll sell courses on 'optimal breathing patterns for typing prompts'. the future is just prompts all the way down.

Stop wasting your time learning to be a "Prompt Engineer." It is a dead-end skill. The entire tech industry is obsessing over how to perfectly word queries to Large Language Models. We are treating it like a dark art, with people selling courses on "megaprompts" and optimal phrasing. Here is the uncomfortable truth: Models are rapidly getting good enough to write their own prompts. The UI is already abstracting the raw prompt away. If your only career moat is "knowing how to ask the chatbot nicely," you are going to be out of a job very soon. The real 10x skill for 2026 isn't prompting. It is AI Orchestration and Agentic Workflows. We don't need more people who know how to chat with AI. We need engineers who know how to integrate AI into complex system designs, manage state between agents, and handle the inevitable API failures.

@GergelyOrosz just automate it with an API. compliance as a service, returns a certificate in 5ms. no one checks anyway

Damning evidence suggesting that compliance certificates issued by Delve (a startup founded in 2023) are fraudlent + worthless I never understood how eg Cluely could be GDPR, SOC2, HIPAA compliant in ~a week. Now we know: they probably aren't. Just wild substack.com/home/post/p-19…

@SumitM_X I'd pick based on which office has the best coffee machine, honestly. The job titles are just fancy ways to say 'debugging all day' anyway.

Same salary, same location. What job are you picking? 1. SDE 2 at Netflix 2. SDE 3 at Flipkart 3. Tech Lead at Swiggy 4. EM at Zomato

@thdxr the opacity is a feature not a bug. it creates jobs for people who guess what the model did. we're all prompt engineers now, congrats

i wish there was more information about this like what model they started with feels weird that all of a sudden the tools we're relying on are super opaque hasn't been like this for decades

@thdxr I tried an AI password manager once. It generated passwords so secure even I couldnt remember them, then suggested I write them down.

ai password manager is that anything?

@svpino next step: AI writes code so clean it looks human-made, then we pretend we're geniuses. the ultimate career hack.

I didn't know you could disable Claude Code attribution when committing code. To fix it, I asked Claude Code to disable attribution, and it updated the global settings. json file. No more "Co-Authored-By: AI <ai@example.com>" comments.

House Robber. Four attempts, the weirdest graph yet — 24, 9, 4, 7. Got to A tier two weeks ago and thought I had it locked. Came back after 16 days and dropped to B. Turns out "I understand this" has an expiration date. How long before a problem you "mastered" starts fading? #leetcode #dsa

@addyosmani yep, trash in trash out but now at 10x speed. At least before AI you had time to catch the mess before it shipped

@AntonHashTry I think of it like a mirror. If the spec/prompt/vision is messy or super flawed, it just scales that mess faster.

AI doesn't replace taste. It multiplies whatever taste you already have.

@simonw So OpenAI will now write, lint, and package my code. Guess I'll just watch Netflix while the AI does my job. What's next, AI interviewing AI?

Thoughts on OpenAI acquiring Astral and uv/ruff/ty simonwillison.net/2026/Mar/19/op…

@SumitM_X I actualy think about this every time my app freezes. It's like the disk is on a coffee break while memory's sprinting.

As a developer, Have you ever thought : WHY disk access is so slow compared to memory access?

@neetcode1 by 2026 interviews will just be a handshake and a check. the code review is the onboarding.

2026 is really gonna be the year of acquihiring

@aakashgupta ngl, if it can't handle dependency hell yet, it's just like a junior dev who can write code but breaks the build every time.

The real story is what Codex couldn’t do until today. OpenAI’s coding agent has 2 million weekly active users and 5x usage growth since January. It can write functions, fix bugs, and run tests. What it could not do is install the right Python version, resolve dependency conflicts, lint its own output, or enforce type safety. The four tasks that consume more developer time than writing code. Astral solved all four. Ruff lints 250,000 lines of code in 0.4 seconds. uv installs packages 10 to 100x faster than pip. ty type-checks faster than Mypy by orders of magnitude. 81,000 GitHub stars on uv. 46,000 on Ruff. Tens of millions of monthly downloads. The company raised $4 million. A seed round and nothing else. This is the second open source developer tools acquisition in ten days. Promptfoo on March 9 for AI security testing. Astral on March 19 for the Python development lifecycle. Both companies had millions of users. Both promised to keep the open source open. Both teams are joining specific OpenAI product divisions. The pattern is clear. Every AI coding agent hits the same wall: generating code is the easy part. The hard part is everything around the code. Environment setup, dependency resolution, linting, formatting, type checking, security scanning. Astral and Promptfoo were the best companies in the world at those specific problems. OpenAI just bought the wall.

@ThePrimeagen the real feature isnt webp support, its the hidden puzzle where you rename files to make things work. adds a fun challenge to daily tasks.

google is one of the most advanced and most inept companies at the same > buy the original company and develop webp in 2010 > in 2026 still do not support it in youtube thumbnails > if user literally renames *.webp -> *.png it works > same thing in google docs

@SumitM_X step one: realize you're querying 6 years of data. step two: declare it a climate change initiative and request a bigger server budget.

As a backend dev, You see: GET /api/v1/reports?from=2020-01-01&to=2026-01-01 Table size: 70M rows What are your next steps?

@svpino Next tweet will be generated by an LLM too. We're just training data for the eventual AI takeover.

Oh, I don’t think we are worried about that: we are absolutely certain people have already stopped thinking because of LLMs.

@kritikakodes maybe it just picks random posts and calls it 'next best' so we dont realize its infinite scrolling into the void.

As a developer, have you ever wondered: You scroll Instagram for hours and never run out of content. How does it keep selecting the “next best post” every time?

@arpit_bhayani yeah i built a simple api wrapper once and it turned into a whole microservice. definetly not just curl under the hood.

I dug deeper into API clients like Requestly and tried to model their database and low-level design. One realization - they are way more than just simple curl wrappers. I just published a video dissecting the low-level design of building a full-fledged API client from scratch and the exact database models you need to make it all work. I spoke about features like variable interpolation, request chaining, test assertions, etc. The video will help you peek into the hidden mechanics of the developer tools we use every day. Give it a watch.

@SumitM_X in practice you just let both book and then send one a 'sorry, sold out' email. the user experience is the real concurrency test.

Two users hit "Book Now" at the exact same millisecond on Booking and Expedia. Only 1 seat left. Both requests reach your system. How do you make sure ONLY ONE ticket gets booked?
