I'm trying to limit twitter usage (usually unsuccessfully, but will try real hard this time). Get in touch on bluesky if you have something important to say.

tl;dr: files are bad, just use sqlite as a file engine, it will be 100% correct and most likely faster than native file operations

Whew, I've been programming in C/C++ and Python for over 10 years each consecutively, totalling over 20 years, and only today I learned that the below two are NOT the same, and it's even worse.
In the "normal" mode when you seek to EOF and write, that's not atomic (obviously). Append mode atomically seeks to EOF right before any write.
So the diff exists most noticeably in parallel-writer scenarios, where append mode is the one you want; in single-writer it's only saving one syscall.
HOWEVER... It's actually up to the file-system to implement this correctly, and... It's explicitly NOT true for NFS, where append-mode writes are NOT atomic afterall.
So really, you cannot actually trust append-mode unless you know for sure all of your users are not using this on NFS.

sorted and rearranged 20+ years old mess of a photo archive using codex: I described to it what kind of sorting operation or comparison or whatever else I want to achieve and it wrote small (lol, 60-300 lines) scripts for me, with dry-run, staging, operation manifests, etc. Magic

How was your weekend? I spent mine launching the Space Shuttle. With NASA code from 1970 that nobody could run for 50 years.

Coding agents continue to amaze me (and human ingenuity too!). Reviving UNIVAC 1100 code from barely readable scans nobody even dared to build and run before? Weekend project for my friend, using his own self-improving harness.
Can only imagine how much stuff can be brought back

codex should have handoff to chatgpt and back, who working on that? sometimes I start talking about something and realize that it is easier done locally with codex, then it requires copying the chat. sometimes I start with codex and realize that I just want to discuss

probably next year it will become feasible project for me (3d reconstruction/infilling will reach an amazing quality and coding agents will be able to one-shot that easily). then it will be better and easier with each passing year. and at some point will not require images at all
English
Oh, this is what I dreamed of for my personal photo archive/timeline reconstruction
Yuan Li@yuanli16342871
Introducing: Long-Tail Internet Photo Reconstruction (CVPR’26) We go beyond densely captured imagery to train more general 3D foundation models for the long tail of noisy, sparse, incomplete Internet photo collections of 3D scenes. Yet, we face a data bottleneck: models need ground truth for these long-tail scenes, which classical SfM fails to provide. How do we bypass it? We break this bottleneck with two key contributions. First, we introduce MegaDepth-X, a large new dataset of scenes with high-quality 3D supervision. Second, we propose a new way to simulate difficult image sets for training. Project page: megadepth-x.github.io

@jtregunna @wbic16 have you ever tried to run a modern game? they can easily push 500 frames per second on a modern hardware _while_ there are also all the "thousands" of services running (mostly idling if it isn't called "windows search" or "defender") in the background.
English
Single core performance doesn't care about your cpu count. One cpu passes data to the GPUs frame buffer at a time... and also, in the 90s when we had 100MHz cpus in our computers, we had maybe a few programs running at the same time, not the thousands that do now. Contention is higher, kernel queue wait times for events and things are higher.
final note i'll give, to render 1 frame of data onto the screen in the absolute theoretically fast way at 100 fps, would mean 10ms is needed to render that one frame, irrespective of what anything else in the computer is doing at the time.
So in the 90s, 94ms could have been enough to consider, but today, it's silly for most applications, the run dialog itself too... the OS is more of a hulk these days and some basic things take longer than they used to, but go faster thanks for frequency.
English
100 MHz was more than adequate to run a GUI. At 100 fps, we had a budget of 1 million cycles per frame.
At 4 GHz with 8 cores, no UI task should ever take more than 1 ms. We have 320 MHz per frame available.
What the actual fuck is Microsoft doing these days?!
Dave W Plummer@davepl1968
I worked on the XP run dialog. I'm a grizzled old man now, barely recognizable in the mirror, but even I think 94ms is a long-assed time to wait for a dialog to open.
English
@todaymare @wbic16 but you also have a separate silicon just for that, all your cpu needs to do is provide some short instructions
English
@wbic16 100MHz gives you 1 million cycles per frame
nowadays screens are worst-case 1920x1080
sir, thats 2073600 memory writes assuming you do nothing else
i'm not saying windows isn't incredibly slow and i agree with the general message but cmon

@thsottiaux when it is running something in the background there is no indication and no way to introspect what is happening, need more visibility. ways to see what plugins/skills add to context
also some chats just randomly disappear? I had some threads there and didn't touch them.

and inputs are highly compressible too: "watched this id video for an hour, listened spotify playlist X, read these urls, talked with Y, here is 500 tokens transcript, food eaten, drinks, air quality". And we already tracking much of that and of the state (down to HR and blood)
English
I wondered: what is the minimum number of parameters to compress you life into with high fidelity. Basically, all we need to reconstruct your day is your coords, poses, id of things around you, etc, mostly listed in the work below. That's physical. Plus your inputs and outputs

I am happy to share that our STAR has been accepted to Eurographics 2026: “How to Build Digital Humans?” It introduces a novel taxonomy and a concise overview of the full creation pipeline, from face and body to hands, garments, and hair. tinyurl.com/5f6u7rks

@xlr8harder I'm not expert either, but vibe made that model a month ago and it still feels more comprehensive than anything I've seen in the press

Heard some apocalyptic takes about the world running out of fertilizers because of the straight closure, made some quick model and visualization. What do you think?
English
I'm a little concerned about fertilizer shortage due to the strait of hormuz blockade. Modern agriculture is fertilizer dependent; long term fertilizer shortages will mean food shortages in some regions. And you can't time-shift demand; growing season is when it is.

@PanAmCD Oh lordy i hope that doesn't mean "no cap" is here to stay!

@matiasgoldberg my first thought, but this time it's different because now you can point you ai agent to failing build and tell it to fix it.
English
why are you fucking torturing me @Microsoft? I don't even use any "files on demand" and want that feature gone and that fucking error comes from nowhere. Why can't you just fucking make that fucking thing you push to billions of computers fucking reliably fucking work?

@teortaxesTex given the mistral reception, with "why would you even release such a shitty model" I can understand labs
English
One thing I respect about the Chinese is they aren't ashamed of open sourcing *shitty* models. "yeah this is the best we could do rn. take it or leave it". Elon is ashamed of Grok 3. For Meta, the mediocrity of Behemoth is a reputation risk. They need to save face.
Pussies.

new h/w features because s/w doesn't have support for them anyway because almost nobody has the h/w required.
One hope for AI enabled future is that we'll have even more tailored s/w to our personal situations.
"Yeah, build everything to my particular hw/config/setup, why not?"
English
we have such a velocity of updates (I just spent half a day updating every device, OS, package manager, appstore, standalone self-updating apps, non-self-updating apps, etc) and yet, we still have deadlock where s/w doesn't support new h/w features and h/w is slow to introduce...

Almost all x64 processors today (Intel/AMD) support advanced instructions such as BMI2, AVX2. Unfortunately, most Linux distributions give you code that is compiled to run on systems without these instructions. It means that you may get inferior performance. Many distributions like RedHat have begun defaulting on processors that have these advanced instructions. Recent versions of the popular Linux distribution Ubuntu offers version of your favourite software compiled with these advanced instructions (x86_64-v3 packages). Unfortunately, as far as I can tell, they are disabled by default and require some work to be enabled. I invite you to experiment.
