julia version existed , https://github.com/Keno/julia-wasm

not actively developed anymore

doesnt it get annoying when you actually have to type two adjacent j ?

when it comes to enabling opportunities i dont think it becomes a matter of shame for them anymore. A lot of people (especially in regions where living is tough and competition is fierce) will do anything by hook or crook to get ahead in competition. And if github contributions is a metric for getting hired or getting noticed then you are going to see it become spammed.

do you print in pla or abs ? how long do pla parts last ? where i live the moisture gets to pla eventually and i cant use it for anything that cant be failproof especially something bearing with a load on it.

leap.nvim

you press a keybind and then press one or two characters , all instances of that character pair in the viewport will get get a hint (a characteror two in highlight) , hit those two hint keys and the cursor jumps to that location

its incredibly fast to navigate around your viewport with this.

its interesting that the inverse distance formula works for the glow effect, but the photon explnation is incorrect, you dont "see" photons that are intersecting the ray path, you only see the photons reaching your eye , the intensity for a pixel should count photons arrivng the camera from the direction of the ray path

Julia gets this right. casting to both double and int, it does both a floating point compare and an integer compare , then AND them and return

onivim also seperated the core functionality of the vim editor into a seperate library libvim , this would have been great for other people looking to make their own gui frontend to vim .

neovim does not give a libneovim, but exposes an rpc where you communicate with neovim running as another process, this I would have thought have more latency but apparently is fast enough , this is how the vscode plugin for neovim is able to provide a near complete vim experience. Other neovim guis like neovide use this too

while technically possible with massive projects like these its not as simple to simply fork it, because of the man hours involved . its better to keep in the product stands enshitification while one uses it or just use something else.

carnot theorem does not put an absolute limit , a carnot cycle can have any efficiency as long as you have reservoirs hot and cold enough ,

besides that if you could be more efficient than carnots cycle at two temperature you can spontaneously extract heat from a cold object and out it in a hot object without any input energy , this would mean you can have perpetual motion . we are not just going to bump a kardashev scale , were going to truly max out and go beyond.

fun fact the U S patent office has been bogged down by so many perpetual motion applications they have made it policy to outright reject such applications without a working model satisfactorily demonstrating it

New comment by arbitrandomuser in "Why is Zig so cool?"

arbitrandomuser — Sat, 08 Nov 2025 09:41:52 +0000

Zig structs are "modules" in themselves, apart from c like struct fields , they can have local variables, structs and functions declared and used inside of them .

in fact files in zig are just structs !

yes but i think branch prediction essentialy makes them zero overhead

>You don't write kernels in Julia.

The package https://github.com/JuliaGPU/KernelAbstractions.jl was specifically designed so that julia can be compiled down to kernels.

Julia's is high level yes, but Julia's semantics allow it to be compiled down to machine code without a "runtime interpretter" . This is a core differentiating feature from Python. Julia can be used to write gpu kernels.

Show HN: Constructive Solid Geometry with Python in the browser

arbitrandomuser — Tue, 26 Aug 2025 21:24:07 +0000

This is a little hobby/side project i've been working on .

Its tool for constructive solid geometry using python which runs in your browser (best viewed on desktop).

The gist of it is it runs in your browser(pyodide) you write high level python which generates the corresponding glsl for your objects signed distance function which is then rendered using webgl (raymarching). The objects can then be converted to an STL (marching cubes) and downloaded

while SDF's for csg has been done before , https://github.com/fogleman/sdf , it requires you to generate the mesh and view it in a seperate viewer . Here instead i render the sdf with a fragment shader onto a canvas.

Python is neat, a lot of people know it or can pick it up fast and i thought its the perfect language for small time 3d printing hobbyist or designers to quickly conjure something up.

P.S , i'm also looking for a job.

The bond energy is also mass . Energy is mass , If you had a nuclear reactor surrounded by gas and this setup ran a turbine which compressed a humungous spring and this whole setup was completely sealed and sits on a gigantic weighing scale. You run the nuclear reactor, the spring compresses gaining potential energy, waste heat goes into the gas molecules as kinetic energy. As the reactor progresses converting "mass to energy" does the weighing scale become lighter ?

I made an account on alphaxiv , seemed interesting to tune into discussions and comments on papers I'm interested in. sadly the only active discussions are around LLM this and LLM that.

The alternative is not programming purely in the repl but to have an editor where you type out your code and from where you can send bits of text to the repl to run and get feedback. All major editors have plugins to do this.

arbitrandomuser — Sat, 19 Apr 2025 05:13:49 +0000

This imo is a shortcoming of vim on modern systems, the action precedes the selection.

I would like to select first have a visual feedback of what I selected before taking action on it . Helix and kakuone have got this right .

I often find myself going to visual mode to emulate this.
