Those poor little AI clouds will never keep people reeled in unless they invent something like CUDA.

Life is hell if the world won't let you be who you were born to be. I'm not sure if I would have made it if I'd been born into a world without computers.

Google used to have a near monopoly on the most expensive, educated, devoted, and conscientiously willful people and imposed very few demands on their time. The lengths to which they were willing to go, to make everything they did with the

Stuff like this is why I built Cosmo. I saw the writing on the wall, when the Java installer started adding toolbars to my browser. I made a solemn vow on that day to never build software that can't run unless my users install someone

It's not possible to reverse. Once you send information to an online service, you should assume it'll become public domain in only a matter of years. Digital information is permanent. Hacks happen. Crypto will be broken. Culture w

Is that an embedded device with a small address space? APE used to require a 47bit address space. The release I published today fixes that. Maybe give it another try?

Cosmo author here. I'm familiar with the new rules. They were first implemented in https://github.com/freebsd/freebsd-src/commit/e0f5c1387df23c... which makes a clear intentional allowance for what APE i

Cosmo author here. Could you please clarify what specific object file features we're abusing? The only hacky thing I did was remove the shebang line, and POSIX was awesome enough to change their rules to let us do it. https:/&#x2

You're basically just benchmarking the WIN32 filesystem versus a Linux VM in that case. The Windows file system is famously slow. It'd make more sense to compare a Cosmo binary running on WIN32 with a WIN32 native program. For exa

Cosmo author here. We used to build our code with musl-cross-make. Once Cosmopolitan got good enough that we could compile GCC using Cosmo, our build latency dropped in half. https://x.com/JustineTunney/status/1726

Wow! This might actually make it possible for Actually Portable Executable to support running on Windows ARM. I'm already putting the ARM code inside all my binaries. There's just never been a way to encode that in the PE headers.

If you're thinking slower than you want about work, then maybe it's because the work isn't worth thinking about. If you're forgetting things at work, then maybe it's because they weren't worth remembering. Abse

It's definitely better than what NVIDIA does, inventing an entirely new ISA each year. If the hardware isn't paying the cost for a frontend, then it shovels the burden onto software. There's a reason every AI app has to bundl

I would have assumed it just decodes the x86 into a 32-bit ARM-like internal ISA, similar to how a JIT works in software. x86 decoding is extremely costly in software if you build an interpreter. Probably like 30% maybe and that's assu

Just get rid of the whole resume / application system. Don't 90% of people get their jobs by knowing people anyway? Or some recruiter finding your GitHub. Applying for jobs with strangers where your competition is a stack of paper

Why does everyone keep repeating this mantra? I wrote the x86 decoder for https://github.com/jart/blink which is based off intel's xed disassembler. It's so tiny to do if you you have the know-how to do it.

How fast do you read? I can visualize just about anything I've ever seen. I can dream of new visual experiences I've never had. I can even rotate shapes in my head. But I dislike words and I read very slowly (only for English thou

Is there a way for me to curl their executable into my UNIX terminal so I can read the assembly? Or does Any Run keep the samples to themselves? I know a lot about portable executable but very little about these online services.

Are you telling me this thing spawned 50 new processes on your computer? Could you zip up all the executable files and whatever it installed and upload it somewhere so we can analyze the assembly?

Got some sleep and took a second look. You actually want: long ax = 1; asm volatile("syscall" : "+a"(ax) : "D"(1), "S"("hello world!\n"), "d"(14) : "rcx", &quot

You want: long ax; asm volatile("syscall" : "=a"(ax) : "0"(1), "D"(1), "S"("hello world!\n"), "d"(14)); You can also say: long ax = 1; asm volatile

My take is more cynical. They actually want your soul. By collecting all the information that was ever used to train the neural network between your ears, they can create a synthetic version of you, to impersonate you, and some might even a
