Ahhh mIRC, jolt cola and an EDU connection at 3AM...

What if the original page is untrustworthy and adds JS?
gct··on Compiler-Assisted Floating-Point Error Analysis and Profiling with FPChecker
Is there actually video of the talk?
gct··on Starship V3
They'll put up thousands more starlinks and track every mobile device on the planet simultaneously, might as well have a homing beacon in your pocket.
gct··on A Declaration of the Independence of Cyberspace
We thought this was so punk back in the day.
gct··on Artemis II safely splashes down
Orbits do not work that way
gct··on Making geo joins faster with H3 indexes
I'd be curious to hear more about how you do the 2 -> 3 embedding there. In S2 it uses cartesian three space, but points are constrained to be unit magnitude. This has advantage and disadvantages obviously.
gct··on Making geo joins faster with H3 indexes
I'd like to hear more about the synthetic part of these three spaces, because S2 works exactly as you say, embedding the 2-sphere in three (cartesian) dimensions. S2 points are always three dimensional.
gct··on Making geo joins faster with H3 indexes
You can do this with [S2](https://s2geometry.io/) as well which has the very nice property that parent cells do indeed always contain their children, and sorting the cell ids puts them into in-order order.
gct··on Data centers in space makes no sense
Mars which is literally covered in poisonous perchlorate soil
gct··on Exe.dev
emacs!
gct··on How I Left YouTube
The Box is very frustrating, especially when there's no one handling the other things, yet you're still not allowed to do them because it'd make the wrong people look bad.
gct··on Leaving Intel
Managers can be lazy just like anyone.
gct··on Leaving Intel
At big tech you have to quantify your value like this regularly, so yeah everyone keeps track of the minutiae.
gct··on An individual can change an organization
This person admits he drove people to quit with his behavior, that goes wayyyyyy beyond trying to get the full details. I've worked with this type before and I can envision the cold sweats in the office as he comes around to hold people hostage explaining every micro-detail of their work until he understands it.
gct··on An individual can change an organization
I've worked with this particular kind of toxic personality, they think until they've personally internalized all the details, that its not "right", and will exhaust everyone doing so.
gct··on An individual can change an organization
One of those that thinks everyone owes them explaining everything to them in every detail or its not "right".
gct··on Charlie Kirk killed at event in Utah
They were also loose powder hand loaded weapons, you could fire three rounds a _minute_ if you were really skilled. Everyone in town had to store their powder in a (secure) communal location because it was, duh, an explosive.
gct··on Everything I know about good API design
Everyone's decided that writing regular software to run locally on a computer is the weird case and so it has to be called "local first".
gct··on Digg.com is back
Let's just start shifting the overton window: let's make all paid advertisement illegal y'all.
gct··on LLM codegen go brrr – Parallelization with Git worktrees and tmux
No wonder software is so slow today when we're this profligate. "let's run four AIs and ignore 3/4 of them!" ugh.
gct··on The FFT Strikes Back: An Efficient Alternative to Self-Attention
They usually have dedicated acceleration hardware, yes: https://www.ti.com/lit/an/sprabb6b/sprabb6b.pdf?ts=174057874...
gct··on Code reviews: A success story
Mandatory CR is mostly a way for mediocre programmers to feel like they're contributing IMHO.
gct··on When you search for ‚Google' on Bing, Bing masquerades as Google
Impossible, HN has assured me that Microsoft has changed.
gct··on Forsp: A Forth+Lisp Hybrid Lambda Calculus Language
A thunk is just a function with no arguments representing a computation. In C++:

  int a=1, b=2; auto thunk = [=]() { return a+b; }
gct··on Fast Fourier Transform in Rust
FFTW will definitely query cpuid at runtime too, since it's piecing together kernels anyways it's not much more work for it to choose to ignore AVX, etc. If you use the [guru interface](https://www.fftw.org/fftw3_doc/Guru-vector-and-transform-siz...) to configure it to work with split arrays (and maybe use FFTW_MEASURE when planning) I think the benchmarks will be a lot more 1:1
gct··on Fast Fourier Transform in Rust
This isn't really apples-to-apples comparing with FFTW.

  1. It's been my experience that distros don't configure AVX properly for it, and 
  2. PhastFT takes its inputs de-interleaved in separate real/imaginary arrays which is generally not how complex data is provided, so that overhead doesn't appear in PhastFT.
gct··on Level of Gaussians: Real-Time View Synthesis for Millions of Square Meters
Given they're indexing into a tree, animation will be a pain.
