buildartefact··on RenderFormer: Neural rendering of triangle meshes with global illumination
For the scenes that they’re showing, 76ms is an eternity. Granted, it will get (a lot) faster but this being better than traditional rendering is a way off yet.
buildartefact··on Triangle splatting: radiance fields represented by triangles

buildartefact··on Reverse engineering of the formula used to generate the "reciprocal tariffs"
Because none of what they call “tariffs imposed on the US” are tariffs. It’s the trade deficit divided by the country’s exports to the US. They’re literally making shit up and expecting stupid people to take it at face value.

They’re imposing tariffs on uninhabited islands. They don’t care enough to even try and make it plausible. That’s how stupid they think their supporters are and how much contempt they have for them.

buildartefact··on TikTok says it is restoring service for U.S. users
I used to believe this vehemently. It has become clear that that’s a notion from a bygone age.

The internet has created a global town square where the loudest voices are the ones that catch people’s attention, regardless of the veracity of their claims. There is no truth any more, only the cult of personality.

Tomorrow the US installs a racist, rapist, treasonous kleptocrat as president because the majority of people are unable to think objectively and swallow his promises at face value, despite every indication that life will be immeasurably worse if you’re not a billionaire oligarch.

buildartefact··on Physically Based Rendering: From Theory to Implementation
What’s hilarious is there’s nothing physically based about the Disney model. It’s empirical and It’s not even energy conserving.

As sibling pointed out, physically based rendering precedes “PBR” by a looong time and goes much, much deeper than “I put a metalness map in my shader”

buildartefact··on Working with jumbo/unity builds in C/C++
They do.
buildartefact··on Gaussian Blue Noise (2022)
In path tracing blue noise does not increase convergence, but does reduce the perceptual error.
buildartefact··on CUDA Is Still a Giant Moat for Nvidia
CUDA IS the merit. They’ve been developing the software stack to make GPU programming accessible for 2 decades now. They’re a software company as much or more than they are a hardware company. Ignoring this fundamentally misunderstands why they’re in the position they’re in now.
buildartefact··on Look, ma, no matrices
This is exactly what the article is about. TLDR they can be roughly equivalent
buildartefact··on Ask HN: How to Learn Cloud Development?
Thanks for the recommendations. I’m definitely planning on trying to build something as I learn so the tip on DigitaOcean is appreciated too.
buildartefact··on An artist fights Midjourney
Asks for screenshot from movie. Image generator gives screenshot from movie. Who’s at fault here?
buildartefact··on Dear ImGui: Graphical User Interface library for C++
egui is pure rust. It is not a rust binding of ImGUI
buildartefact··on Show HN: A pure C89 implementation of Go channels, with blocking selects
Do you know of a good style guide that encapsulates common conventions like create/destroy?
buildartefact··on Ripgrep is faster than grep, ag, Git grep, ucg, pt, sift (2016)
PowerShell is the worst of all worlds. Its a terrible shell compared to bash/zsh/whateversh, and for anything complex enough to need a long script you’re far better off in Python.
buildartefact··on Light can make water evaporate without heat
That’s for sRGB, which as for most colour spaces is defined relative to CIE XYZ, which is itself defined in terms of the perception of a “standard human observer”. In XYZ, the Y coordinate is the luminance (brightness) of the colour and that first equation is computing Y from the RGB value
buildartefact··on Marcel the Shell
The worst part of it is they aliased a bunch of common posix command names to their power shell equivalents but then they have different flags or semantics. Works fine until it trips you up destructively.
buildartefact··on Maybe Rust isn’t a good tool for massively concurrent, userspace software
>There's no option to "turn the borrow checker off" - which means that when you're in prototyping mode, you pay this huge productivity penalty for no benefit

That’s not really true. The standard workaround for this is just to .clone() or Rc<RefCell<>> to unblock yourself, then come back later and fix it.

It is true that this needs to be done with some care otherwise you can end up infecting your whole codebase with the “workaround”. That comes with experience.

buildartefact··on Maybe Rust isn’t a good tool for massively concurrent, userspace software
You’re seriously suggesting writing a game engine in Python?
buildartefact··on Jai Programming Language – Resources and Information
It means if you don’t like it, or take any objection to its design then you are not a good programmer and just don’t “get it”.

Considering the author, it’s completely unsurprising.

buildartefact··on Making C++ safe without borrow checking, reference counting, or tracing GC
And you pay for that in performance
buildartefact··on WezTerm is a GPU-accelerated cross-platform terminal emulator written in Rust
GPU-accelerated terminals have been a thing for a long time.
buildartefact··on New EU law could force Apple to allow other app stores, sideloading, and more
In what way is that better? Jailbroken iPhones represent a tiny fraction of the devices out there. So now we have to expose everyone for the sake of the “WAlLeD gaRdEn” minority?
buildartefact··on New EU law could force Apple to allow other app stores, sideloading, and more
Can’t wait for every company to have their own App Store I need to install just to download the one app I want. All the inevitable data mining and security bugs will just be the icing on the cake!
buildartefact··on It’s easy to become obese in America. These 7 charts explain why
Similar story for me, though I only roughly count calories. Stick to it aggressively during the week, relax at little at weekends, don’t beat myself up if I go out and get trashed occasionally then eat a whole tub of ice cream.

I’ve been weighing myself every morning and tracking it in a google sheet and that’s been key for me. it’s interesting watching the spikes on the weekends. Makes it really easy to understand the consequences of my choices.

I’ve lost nearly 20kg over the past 6 months or so and it’s been… easy? Just a few more to go.

buildartefact··on An elegy for GNU and RMS
> Emacs is not an independent project, and it isn't governed by its contributors. I'm the head of the GNU Project, and that includes Emacs.

I think it might be you that’s missing the irony.

buildartefact··on An elegy for GNU and RMS
Probably an irrelevance thanks to the GPL. We should all be grateful RMS missed that email.
buildartefact··on Ask HN: How to cancel Adobe CC subscription without paying a “cancellation fee”?
Pay it. Then tweet @ them how disgruntled you are that you have to pay it. Worked for a buddy of mine.
buildartefact··on Implementing a Spinlock in C++
It was in response to this blog post: https://probablydance.com/2019/12/30/measuring-mutexes-spinl...

Basically your standard CAS loop with _mm_pause() to yield.

buildartefact··on Implementing a Spinlock in C++
Obligatory: “ I repeat: do not use spinlocks in user space, unless you actually know what you're doing. And be aware that the likelihood that you know what you are doing is basically nil.”

buildartefact··on EA announces kernel-level anti-cheat system for PC games
Escape from Tarkov does all those things apart from coffee shops and shadow banning and still has a massive cheating problem.
