Turns out that the HN flagging mechanism hides the message from their auth check, so the spam doesn't actually work anyway. Oh well.

Highly recommend qemu instead. The sandbox machines are just more IP addresses on the local network. If you want them completely offline, put them on a network that doesn't have a route to anywhere. The sketchy AI harness is very happy

This is really important. I am already tired of hoarding rclone copies of huggingface torrents and periodically checking them for bitrot. Pirateface is not a very helpful name for it though and it doesn't seem to have scripted torrent

Bastard thing corrupted some of my source code that was "on a shelf". Just gone, no path to retrieving, reimplement it. About a decade ago now and I'm still angry about it. Don't lose the work is table stakes for source

You prefer having the harness execute any markdown that looks like it might be a tool call? I had a bad time getting that to work reliably whereas a grammar in the sampler gets it right every time.

I really like the json schemas around the tool calls. Much stricter validation than in codex. Git might be worth adding to the top level. Currently you've got LSP, grep, glob nicely structured for non-mutating queries across a codebase

Libxml2 segv when the input is large and the transform complicated was something of a surprise to me. Parsing xml is easy enough but I think implementing xslt is going to be a nuisance.

That's the any type and the moving logic into json loaded at runtime features

This only holds if society manages to hang together, which in the age of military strategy written by AI is looking borderline.

It won't last. You need a good grade to find work after so handing out lower grades decreases applications next year. On the plus side, high grade + long ago remains a signal.

Scale is a cuda implementation running on nvidia or amdgpu. Think nvcc semantics with template diagnostics by clang. Nvidia including Spectral in their inception programs seems a big deal to me. It bodes well for the future of the cuda ecos

Not imaginary. Eliding checks on nullptr and integer overflow were both implemented, shipped, miscompiled the linux kernel and grew flags to disable them. I expect there are more if one goes looking.

Well, you can't write malloc in conforming C, which hurts rather more than remembering to write bitcast as memcpy on char pointers. Doesn't matter though because you aren't writing standards conforming C. You're writing

You too can solve maths problems by: 1. Generating enormous amounts of text 2. Persuading a mathematician to look closely at it 3. Announcing success if they conclude it is a proof This is deeply disappointing relative to "chatgpt foun

I found a 5gbe one that claimed 60W, will power a phone but not the low power laptop I've got here. It probably isn't far off.

Ymmv. I've got a mix of cheap premade patch cables and some I crimped from solid core, all cat5e, all holding 10gbe totally happily. I suspect that only works because they're a meter or two long but that reaches across the rack.

It would do nothing. You'd get an increase in derivatives volume with the same underlying effect.

Anyone worked out how much hardware one needs to self host this one?

Get out seems an important priority. Good luck

Who makes the bar for "good at delivering tech" if the guy pushing spacex, starlink and tesla simultaneously doesn't reach it?

The existing work is all of software dev. The program did what it was told to do, not what people wanted it to do, is rather a lot of the profession.

This was _really_ surprising to me. What's the point of marking individual stores if it affects everything, not just that address. But yeah, what I can find online agrees that C++ has done this. Thanks!

I've stopped reading anything on blogs on the basis that it's now probably llm spew and life is too short for the signal to noise ratio that implies. With the exception of things that places like HN seems to consider worth reading

If it's a power of two, you don't need the branch at all. Let the unsigned index wrap.

Push: buffer_[head] = value; head_.store(next_head, std::memory_order_release); return true; There's no relationship between the two written variables. Stores to the two are independent and can be reordered. The aq/rel applies to

It's obviously, trivially broken. Stores the index before storing the value, so the other thread reads nonsense whenever the race goes against it. Also doesn't have fences on the store, has extra branches that shouldn't be th

If you can get a megawatt into the car batteries without setting them on fire, that's game over for petrol cars. And for the other electric vehicles that haven't worked it out yet. Only reason I'm on petrol is unwillingness t
