I don't understand why they don't just double down on these #include <__fwd/vector.h> etc. headers. They fix everything. The only downside to them is I can't use them on a header that defines a class with std::vect

Sounds par for the course with the Biden administration. Watch what Ben and Marc have to say about them: https://www.youtube.com/watch?v=g4jWb-0nj44 They talk about how Biden has spent the last four years going beyond the l

I'm defending open source developers. We can't freely modify open source code if it has glacial build times. It's specifically because people are volunteering that we should aim to be as conscientious as possible when it come

Programming is the process of manipulating data structures, so if you're building a JSON server, then every piece of code in your server is going to be dealing with and operating on JSON data structures. It can't be neatly tucked

Just because I included an rvalue constructor doesn't make it C++11. This library was originally written in C. It hasn't changed a whole lot since Gautham and I originally wrote it: https://github.com/jart/cos

I just wrote a new server instead. There's nothing I won't do, no lengths I'm not willing to go, when it comes to cutting back on build latency.

Yes they'd be very trivial to remove locally. It might also be nice to have #ifdef statements around them like we're already doing for std::string_view. If we consider that many big name C projects like curl are still on C89 then

Compile time is a collective problem and usability is an individual problem. I work with llama.cpp. The files in that codebase that were made using nlohmann json take about a minute to compile using g++ -O3 -g, all because one guy who origi

Thompson Pike encoding. It predates the UTF-8 standard and was invented on a napkin in a New Jersey diner. It allows the full spectrum of 32-bit numbers to be encoded, rather than restricting characters to only those also present in UTF-16.

This library supports building with C++11. I haven't tried compiling it with an older standard, but I imagine it might work. One thing I like about the C++11 compilers like GCC 4.9 is they build code magnificently faster than recent ed

I've added benchmarks to the readme. https://github.com/jart/json.cpp?tab=readme-ov-file#benchmar... You're looking at a 2x or 3x performance advantage across the board. If you include invalid JSON handling,

That might actually be the explanation for why json.cpp benchmarks 39x faster than nlohmann's library if I include the failure test cases.

That TinyPilot is really cool. It deserves to take off. I'm surprised he's still bootstrapping at this point, because with a product like that, there's a lot more to gain than there is to lose by taking angel and VC money.

Saying cars are a political choice assumes we live in a command and control society. Saying "we" in this context assumes you have political power.

Ah gotcha. So the cynical thing I thought would happen already happened. Glad to hear we're on a road where peak cynicism is looking behind us.

I thought that (1) meth (e.g. methylphenidate a.k.a. ritalin) blocks reuptake of dopamine, and (2) amphetamine (e.g. dextroamphetamine) stimulates production of dopamine, and (3) methamphetamine (a.k.a. desoxyn) does both. Is that understan

How can you believe you've been taking a placebo for years? Phenylephrine is used for the illicit synthesis of methamphetamine, so there's an inherent bias towards anything that gets it off the shelves. Cherry picking studies that

Nah you make sure X% of your team is staffed with losers. It's a nutty system I know. But I'd imagine that's how things worked at companies that have stack ratings. Managers probably traded low performers like baseball cards.

What if you've got a Symbolics 3600 which has 36 bit words? Your suggestion will break on that. We clearly want uint_least32_t.

If you don't want a hard coded table, you could always do this. unsigned kCastagnoli[256]; void InitializeCrc32(unsigned table[256], unsigned polynomial) { unsigned d, i, r; for (d = 0; d < 256; ++d) {

I don't want to require everyone who builds llamafile from source need to install rust. I don't even require that people install the gperf command, since I can build gperf as a 700kb actually portable executable and vendor it in t

What makes you think I care about convincing you? These days every shot caller on earth is scrambling to get piece of AI. Either by investing in it or fighting it. You come across as someone who wants to hate on AI. Haters aren't even
