xiaodai··on Show HN: Vortex – a high-performance columnar file format
I see. Very nice. So it's a trade-off. I imagine the throughput of these light-weight compression suffers a little. In analytical workloads, it's common to do things like compute the mean of a vector or compute the gradient for this batch of data so random access appear less of an issue here.

There are a bunch of these including fst in the R ecosystem. JDF.jl in the julia ecosystem etc.
xiaodai··on Windows 11 24H2 hoards 8.63 GB of junk you can't delete
disk swap files?
xiaodai··on Kotlin Money
cool. whoever uses these libraries better validated it very well.
xiaodai··on HPy – A better C API for Python
Is this thing “official”?
xiaodai··on Statisticians use a technique that leverages randomness to deal with the unknown
I don’t know. I find quanta articles very high noise. It’s always hyping something
xiaodai··on Python for Inversive and Hyperbolic Geometry
I am sorry. I am autistic.
xiaodai··on Show HN: Quadratic – native JavaScript support in a spreadsheet
U can still google resolver one or was revolver one. It was bascilly the same thing but python.

xiaodai··on COBOL has been “dead” for so long, my grandpa wrote about it
ocaml, f# and haskell

> scala did get some things right that other mainstream languages still have not

Examples?

xiaodai··on Show HN: Quadratic – native JavaScript support in a spreadsheet
These approach has been tried so many times and has failed so many times that it’s not funny
xiaodai··on Python for Inversive and Hyperbolic Geometry
Python is a very poor choice for such a tool. Julia should have been used
xiaodai··on Why is F# code robust and reliable?
Haskell, Ocaml, scala

anything else?

xiaodai··on The RedMonk Programming Language Rankings: June 2024
Hackernews amplifies alot of stuff
xiaodai··on A plucked string simulator using Julia
What does Julia have to do with this?
xiaodai··on Show HN: Put this touch sensor on a robot and learn super precise tasks
can make a self massaging robot. where you pressure is where the robotic arm will massage, to the strength u need.
xiaodai··on A high-performance, zero-overhead, extensible Python compiler using LLVM
Please stop trying to make python fast. Move over to Julia already.
xiaodai··on Vapour: A typed superset of the R programming language
Never thought someone would do this for R. Really nice work.

Vapour is an interesting choice. Hope it’s in name only :)

xiaodai··on What are the best options for Amazon SDEs thinking about leaving over RTO policy
they figured you have no where to go
xiaodai··on Fractran
this is cool but it was known that sqrt(2) is NOT representable exactly by fractions so i don't think this will really improve anything. floating point can't remember numbers exactly, nor can this architecture.
xiaodai··on The book documenting the curl project, the curl tool, libcurl and more
btw, what if the curl maintainer dies? should we set up a company and charging for newer versions of curl?
xiaodai··on Writing an OS in Rust
Makes sense but what if there are bugs in llvm? U r still exposed. So need a rust version of llvm and then rust can be self hosted
xiaodai··on Kolmogorov-Arnold networks may make neural networks more understandable
It doesn't that's the problem
xiaodai··on Micrograd.jl
the deep learning libraries. can't figure out why one of my gradient didn't work so i switch implementation to pytorch and it worked perfectly fine.
xiaodai··on Micrograd.jl
yeah. unless Julia has some killer framework with massive investment, it's hard to see 99.99% of cases moving to Julia. No point really.
xiaodai··on Gdi.js: JavaScript Runtime Written in Object Pascal
second object pascal related post on front. is there a retro trend going on in programming? like pixel graphics games in gaming?
xiaodai··on Oxygene: A modern language built on the foundation of Object Pascal
not really a language but more of a Delphi competition. Delphi is still alive and kicking so there's a market for RAD for sure.
xiaodai··on 2M users but no money in the bank
