We made a spreadsheet on top of OT several years ago. Most OT related documentation doesn't talk about how to do this. But it worked pretty well for us.

Yes, I think it would be a good paper. I made a tiny self contained implementation of this algorithm here if anyone is curious: https://github.com/josephg/crdt-from-scratch/blob/master/crd... FugueMax (o

Yes, exactly. I went on holiday to Cairo a few years ago. Small bribes (bashish) is 100% normal there. My tour guide was this bright 22 year old who dreamed of going to the UK to be an uber driver, so he could make enough money to get marri

You don't need to program in ASM or C to write a memory efficient program. Swift, Go, Rust, C++ and C# are all reasonably memory efficient at the scales we're talking about. Usually you just have to actually look at memory usage

by josephg 8mo ago
Yep. Even the framework seems to be moving to soldered on ram.
518.
by josephg 8mo ago
Good. So many software developers have gotten so lazy with RAM usage in the past few decades. I hope the Neo is a kick in the pants to get everyone in the Apple ecosystem to take memory usage seriously. More efficient software benefits ever
519.
by josephg 8mo ago
Yeah. Also the bandwidth of modern soldered-on Mac SSDs is insane compared to where it was in the Intel era. The performance impact of moving applications in and out of swap should be much lower than it was a few years ago.

Sometimes I wonder if package names, bucket names, github account names and so on should use a naming scheme like discord. Eg, @sometag-xxxx where xxxx is a random 4 digit code. Its sort of a middleground between UUID account names and comp

522.
by josephg 8mo ago
Personally I think a lot of programmers care way too much about consistency. It just doesn't matter that much if two files use indentation / braces slightly differently. In many cases, it just doesn't matter that much.

Yep this has been my experience too. I tried GPT3.5 for translating code from typescript to rust. It made many mistakes in rust. It couldn't fix borrow checker issues. The context was so small that I could only feed it small amounts of

What is untrue about this statement you quoted?
526.
by josephg 8mo ago
Yes; I think this remains true with coding agents. If you need to do some exploration of the solution space, it makes sense to do that before writing tests. Once you have a clear, workable design, you can get the agent to make a battery of

by josephg 8mo ago
Testing works because tests are (essentially) a second, crappy implementation of your software. Tests only pass if both implementations of your software behave the same way. Usually that will only happen if the test and the code are both co

Open models do exist. They’re nowhere near aa good as frontier models, but they’re getting better all the time. It’s probably only a matter of time before open models are as good as Claude code is today.

How would a compiler toolchain ship a debugger for webassembly? It’s kind of impossible. The only place for a debugger is inside the browser. Just like we do now with dev tools, JavaScript, typescript and webassembly languages. > The bro

1. It’s not just one use case. I’m working on a product which makes heavy use of indexeddb from JavaScript for offline access. We’d love to rewrite this code into rust & webassembly, but performance might get worse if we did so because

I completely agree. Right now you can point claude at any program and ask it to analyse it, write an architecture document describing all the functionality. Then clear memory and get it to code against that architecture document. You can&#x

If you write program A that does something, and I look at what your program does and write program B that does the same thing, have I copied your program? So long as I didn’t copy any of the lines of code in program A directly, no. At least

Except nobody writes code like that. It would be horrible. Sync functions perform better than async functions, and they give more guarantees to the caller. They're strictly better, when you can use them. If you find yourself making eve

This works a lot better in JavaScript, which is exactly this model - a single threaded executor with async await. The problem you talk about is solved with function colouring. Async functions are marked as such. In general, sync functions c

Those are lovely data structures and I know about them. But how are you planning on using those data structures? What CRDT are you building? You might also be interested in Alex Good's Beelay algorithm: https://www.youtube.c
