This reminds me of stuff like interns wiping the production servers.

The solution in the comments there is always "have backups" and "why can an intern do that stuff? why arent policies set".

But I dont think these can be applied to something like openclaw agents

I did the same with an rpi3, not sure if I used this guide but it seems good:

i think so. The biggest hurdle with new languages is that you are cut off from a 3rdparty library ecosystem. Being compatible with C 3rd party libraries is a big win.

Tangential, but Flash had a nice side effect that the "app" could be exported in a self contained way via SWF.

Exporting this site for example in a future proof way is not that obvious. (Exporting as pdf wont work with the webgl applets, exporting the html page might work but is error prone depending in the website structure)

50 years from now, flash emulators will still work on swf files, but these sites might be lost. Or is there a way to archive sites like this?

>The user writes the data to CPU mapped GPU memory first and then issues a copy command, which transforms the data to optimal compressed format.

Wouldnt this mean double gpu memory usage for uploading a potentially large image? (Even if just for the time the copy is finished)

Vulkan lets the user copy from cpu (host_visible) memory to gpu (device_local) memory without an intermediate gpu buffer, afaik there is no double vram usage there but i might be wrong on that.

Great article btw. I hope something comes out of this!

What has changed now in the memory landscape/ai workload in the recent months compared to summer or spring?

My takeaway is that sandboxing should be more readily available, and integrated into the OS.

I used sandboxie a while ago for stuff like this, but afaik windows has some sandbox built into it since a few years which I didnt think about until now.

Why not get the wifi enabled fridge and just not hook it up to your router?

Genuinely asking because I plan to do this once I have to get new appliances, is there something missing that way?

New comment by zbendefy in "What to do with C++ modules?"

zbendefy — Mon, 01 Sep 2025 11:53:37 +0000

Thing is (correct.me if Im wrong), that if you use modules, all of your code need to use modules (e.g. you cant have mixed #include and import ; in your project). Which rules out a lot of 3rd party code you might want to depend on.

New comment by zbendefy in "From XML to JSON to CBOR"

zbendefy — Wed, 30 Jul 2025 12:17:47 +0000

How different is CBOR compared to BSON? Both seem to be binary json-like representations.

Edit: BSON seems to contain more data types than JSON, and as such it is more complex, whereas CBOR doesn't add to JSON's existing structure.

its 12 years not 22.

An embedded device bought today may be easily in use 12 years from now.

This is such a good analogy. Awereness about social media shluld be like awereness about junk food you consume.

Correction, I didnt remember correctly as those are actually there in the code release, here is the r200 (radeon 8500) renderer specific code:

Not just that, they had specific renderer backends, one for GeForce, one for GeForce3, one for Radeon 8500 that they had to cut out as they used proprietary information or code perhaps.

New comment by zbendefy in "How do modern compilers choose which variables to put in registers?"

zbendefy — Mon, 17 Feb 2025 15:08:04 +0000

Aren't registers fixed by x86_64, while cache is a CPU hardware specific thing (e.g.: newer cpus have more cache than older ones, bit register count is fixed 8 on x86 and 16 on x86_64)?

So I think the compiler can work with registers at compile time but cant work with an unknown structure of cache

No, the full R1 model is ~650GB. There are quantized version that quantize it down to ~150GB.

What you can run locally are the distilled models, that is actually LLama and Qwen weights further trained on R1's output
