It’s Ukraine’s turn to ask if we even said β€œthank you”.

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.

Back in my day you needed a senior engineer for this sort of thing

Jfc if you wanted to flex with your military, all you had to do is up your defence support for Ukraine - we'd welcome it, you'd actually stop an ongoing war like you claimed to with so many, save countless lives, gain reliable allies - but no, why bother when you can start a war of your own.

C’mon, people. Look at your Kremlin style guide. The phrase is β€œspecial military operation.” Not all of you are getting this right.

Sounds like it's you who'd want customisable keybindings πŸ˜…

05.03.2026 13:22 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Not really, I don't care about customisable key bindings, I just constantly expect it to behave just like VSCode _especially_ because the editor looks the same, and Ctrl+D is something I use all the time for quick renames / find-replace :)

I mean at least that's the official goal.

I'm not sure if "desktop app" APIs fit into WinterTC.

It's supposed to standardise a minimum common APIs shared by browsers and server-side runtimes alike, and things like clipboard or USB just don't make sense in environments like CF Workers / Shopify Functions / etc.

Oh yeah, but it has cutomisable keybindings.

For example, one I'm always tripped up by is Ctrl+D duplicating the selected text instead of selecting next occurrence like in VSCode.

If anyone is friends with any Georgian air traffic controllers, buy them a nice bottle of wine. As guardians of pretty much the only narrow gap still available between Europe and Asia that avoids both Iran, the Gulf, Ukraine and Russia, they are under some substantial pressure.

As for profitability, yeah, as far as I can tell up until roughly a decade ago they had decent margins on OS through OEM licensing in particular. The restructuring to treat it as a platform to sell other stuff on came after that (and it's very obvious, cause that's right after first Win 10).

04.03.2026 16:10 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

Nah, I appreciated their push to touch friendly UI even when other companies lagged behind (some still do).

When someone says β€žScientists do not want you to knowβ€œ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

The "modular" part itself doesn't sound bad, and something people actually wanted for years, but I don't want the damn copilot in every single goddamn app and OS component.

I get OS is not a profitable business anymore, but users hate and will always hate the bait&switches to subscription models.

As many of my colleagues know too well, I've been pretty bullish on developing on Windows for most of my career.

I loved the UX and DX direction that got them to Windows 10 and I still see some great work done in WSL and kernel, but my heart can't take the UX butchering they've been doing since.

Aka, it's still an abstraction layer but it might be a sibling to existing ones not always sitting atop.

But seeing models already comfortably analysing binary executables, because all that lower-level programming was *also* in the training data, I could totally see straight LLM->AST, LLM->asm and even LLM->binary compilers being feasible as well.
