What is the first thing you should do when starting a new PostgreSQL project that will save you countless headaches? https://t.co/63UoFiYU01

You’ve spent weeks, maybe a few months, developing a prototype locally with a local PostgreSQL in docker, not worrying about a thing.But now the moment has come, and you must push to prod.You start...

The modern world has made huge advances in knowledge, technology, and skill. We can build faster than ever. We know more than ever. Yet quality still feels so rare. So many things feel unfinished, broken, or forgettable. Why? → https://t.co/gfZewHEavw

Epic!
Another advantage of AOT repositories: they make query debugging easier. Sneak peek at @intellijidea 2025.3:

<rant> A periodic reminder that Sprints, Backlogs, Daily Scrums, Scrum Boards, Scrum Masters, Product Owners, Points, Velocity, PIs, etc., have NOTHING AT ALL to do with "Agile." Agility comes from working small, delivering frequently for feedback from actual customers, and

This friday I had a "just use postgres for queues" talk on @techmeetupcz, it was recorded, hopefully will be shared soon!
Forget Kafka and Just Use Postgres (until it breaks). You may think I'm rage-baiting but I actually mean it. Here's why orgs jump to Kafka prematurely:👇

However I do think that on a project with strong quality gates and high alignment, not everything needs a human review.

Hard disagree. I've seen typo fixes fucking up master, its never worth it to skip PR pipeline. Instead, fix your shitty pipelines so that they don't repeat the work on master that was already verified on a rebased branch.

I've always wanted to build dev tools, but it always felt like everything already exists and has a huge head start. Now it feels like it's possible to innovate again, and l'm having major FOMO.

When I started working in python, I got lazy with “single assignment”, and I need to nudge myself about it. You should strive to never reassign or update a variable outside of true iterative calculations in loops. Having all the intermediate calculations still available is

> without structure like types, tests, or clear architecture, you end up in these weird loops where the model keeps regenerating the same broken thing because it lost context three prompts ago Exactly what my talk was about:

If you compare throwing random prompts at AI-assisted coding tools and being deliberate and structured about what you give them, you’ll see a big difference in the usefulness of the results.In this...
@alex_prompter honestly the paper isn't really saying vibe coding is official. it's documenting why it breaks in practice. the researchers found that the actual problem isn't whether ai can generate code anymore. it's that without structure like types, tests, or clear architecture you end up

I've managed to rinse off my phone from ocean water and dry it faster than it takes to load @linear on slow internet. Not kidding. People that make productivity apps should have permanently enabled GPRS throttling in their browser.

We split our monolith into microservices. It was a mistake. Before: - One Rails app - 200k lines of code - Deploy time: 8 minutes - 5 person team After the split: - 8 microservices - Separate databases - Message queues everywhere - Service mesh for communication What actually

A lot of good programming is working within constraints that you only figure out after years of deploying to prod. You could name that variable “x” but it’s much nicer to call it “items_sorted_by_price,” especially at 3 am on PagerDuty.

AWS US-EAST-1 is down. A major AWS outage has taken down several popular services worldwide, including Signal, Fortnite, Alexa, Snapchat and many more. The specific cause of the service outage is currently unclear, according to AWS and they are working on fix.
