I just extended the Black Friday sale to the whole month of November! All my existing full-week flagship courses are heavily discounted for the entire month, and more content coming soon! tanelpoder.com/posts/black-fr…
Inexperienced specialists in some field tend to think they look smart if they use complicated terminology and abbreviations when talking about that field. This is false belief. They look dumb when talking to more experienced colleagues, who prefer using clear language with simple…
this repo deserves more stars github.com/postgres-ai/po… gitlab.com/postgres-ai/po… we aim to have the most detailed and advanced monitoring for Postgres -- and it's FOSS because it's just a foundation of something bigger (after 20 years with Postgres, next month will be the most…

I would like to thank the haters for helping me promote the new PlanetScale $5 plan all day. Thanks guys. That's right $5.
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…
The developer VM has been freshened up! Go get some! oracle.com/database/techn…
Lambda syntax varies widely across languages; more widely, I think, than other language features. I wish it weren't so. It's difficult to see the elegance in a new language if the syntax is unfamiliar.
It's so great to be in New Orleans for @confluentinc's #current25 conference! I'll be speaking about @morel_lang tomorrow at 2:45 PM.
We shipped! blog.cloudflare.com/workers-tracin… This has been so much fun to work on.
Postgres \watch {n} will run the same action again and again after n number of seconds. For example you could watch the pg_stat_activity table every 3 seconds with: select * from pg_stat_activity; \watch 3
Take a moment to appreciate all the Windows support engineers getting late night rebooty calls this weekend
My explanation that making computer chips is basically the same process as developing film in a dark room is woefully out of date.
The mind-blowing tech behind microchip manufacturing. Lasers fire 50,000 times per second at tin droplets moving 100 m/s, creating extreme ultraviolet light plasma — and that’s just one step inside ASML’s chip-making machine.
Neat work, as far as explains go I love DuckDB's explains - both the console graph, as well as the web tool (db.cs.uni-tuebingen.de) - esp. the visual cues for slow operations or these with large resultsets.
