This is exactly the same thing with the car horn: in some countries it seems to be used for "hey you, unprotected person, do NOT swerve right now, I am passing you with my car" versus in Sweden where I live, your'e not allowed that usage at all.

Also in Sweden, you do only use the bell if really needed.

"Do horns and bells really prevent accidents?"

If you are a sane person, absolutely not!! You _try_ the bell, if people react, then you go. Many times it just confuses people or people ignore it.

If you are a high-speed maniac and _rely_ on the bell to clear a path for you... then yeah. But you are then also likely to take great risks in general and will probably be in other accidents...

Agree, I never actually had great success with Opus. I think its the failures that are annoying, its probably better than codex when its "good", but it fails in annoying ways that I think codex very seldom does.

I really liked this video! Orbits are hard to visualize but I think the choices here were very good.

I would not call any Apple phone even mid-range, and certainly not low-end?

This coming from an android user, that recently bought iphones for my daughters. Paying 600$ for not even top-of-the-line phones does not scream low-end to me.

This is my pet peeve with LLMs, they almost always fails to write like a normal human would. Mentioning logs, or other meta-things which is not at all interesting.

Wow, I had no idea that excalidraw could "import" mermaid!! This is just awesome.. I can have my LLM generate mermaid, which it is really very good at. And then I can edit the diagram!

Oh, esphome is more than only esp32 these days. For one it always worked on the pre-esp32 ESPs. But yeah, RPI2040, nrf52 and a couple of other platforms work too.

I dont know nothing about this particular leak, but I have worked at Skatteverket.

Let me just say, the likelihood that CGI would have any _actual_ real personal data is close to 0%, at least on servers outside of Skatteverket. I had access to absolutely nothing even working inside. I have never worked in a more closed-down system, maybe excepting the swedish military "complex". No, actually that was less locked down in a way, at least once you were "inside" the system.

I would be REALLY REALLY impressed if it manages to do this without bugs. Just using pythons textual can be very complex, belive it or not. Maaging not only to that but other frameworks too sounds insanely complex. I have a strong feeling this is vibecoded from the commit history?`

Ah yes, it says clearly that on the github page. Still, if its works, I am then impressed by the LLM.

Edit: It does, in fact, NOT work for code export. Level of impressiveness massively dropped.

As overseeing backing up, from various optical media to disk, just don't use the optical stuff!

This was a huge international conglomerate, doing CD backups for decades. Now it turns out these precious backups only worked 96-98% of the time. Terrible stuff.

sandos — Wed, 25 Feb 2026 11:13:28 +0000

I as a "developer", I have probably used less than 10% of my time coding the last 15 or so years... I switched jobs to being a contractor in 2011, and after that it has been a downward slope towards less and less coding, and more of other things. Mostly validation and testing in various forms.

Meh, I still only buy the two-dial microwaves. They are both the cheapest and best at the same time!

Seriosly? They leak emissions if you OPEN THE DOOR WHILE ITS RUNNING?

I thought they were actually, like, certified? How can this not have been tested and fixed... shutting down the magnetron can not take long, right? Making it react fast enough doesnt feel like an intractable problem at all!

I mean this is coming to the same result as heywhatsthat, apparently using the same dataset. Sadly it is not really correct, in that I think it blends a lot of things, including TREEs into the height. Its very obvious many places that some height is just not true, unless you account for buildings and treetops.

I believe I _might_ have a 33km view FROM MY ROOF, from 2m above ground I have much less than 1 km.

I have to 1000% agree with this. In a large codebase they also miss stuff. Actually, even at 10kloc the problems beging, UNLESS youre code is perfectly designed.

But which codebase is perfect, really?

You can't possibly cram everything into AGENTS, also LLMs still do not perfectly give the same weight to all of its context, ie. it still ignores instructions.

Yeah, I tried various very sane-looking instrucions file when starting to use copilot 6 months ago. Turned out it was not really useful. It mostly follows the rules anyway, but it also often forgot to. So turns out, especially with the fast turnaround with models today, it was better to just forego these instructions files.
