We are planning to release new Mastodon security updates for versions 4.1, 4.2 and nightly this Thursday, Jul 04, at 15:00 UTC. It solves multiple security issues, including a major one. We encourage server administrators to plan for a timely upgrade to ensure their Mastodon server is protected.

I can't believe how useful #interactive messing with SDFs is.

Several transformations chained? No problem, color the data according to whichever transform you want.
Need to see uniformity? Draw a grid.

I did like a hundred iterations within the hour!

Last time I used test-driven #development . Good for conformance, bad for spotting glaring bugs. Visual #debugging is powerful.

Universities are using a range of surveillance tools to track and potentially retaliate against student protesters. Activists need to take precautions and think through the changing risks on college campuses. https://www.eff.org/deeplinks/2024/06/surveillance-defense-campus-protests

This only took 2 hours, but I derived and debugged it.

My Equal Area Hemi-goofball #Projection .

I promise I'm going to make bad use of it.

// c = [r; φ]: [0;1], [0; τ]
// return [φ, η]: [0; τ/4], [0;τ]
// hemisphere only!
vec2 myEqualAreaCircleToSphere(vec2 c) {
if (c.x > 1.0) {1.0 / 0.0;}
float r = c.x * sqrt(2.);
float q = 1.0 - r * r * 0.5;
return vec2(asin(sqrt(1.0 - q*q)), c.y);
}

PS. Take breaks for thinking.

Trying to map a surface onto a whole (hemi)sphere, covering it as uniformly as feasible.

(This is another crazy secret #SDF project.)

Lambert Equal Area projection only has 2 sources: #Wikipedia and #PROJ . The equation doesn't nearly cover the hemisphere :/

Just look at this junk!

I'll have to derive the correction factor myself...

Interoperability makes good things great! We deserve the right to repair our devices and move from one platform to another. Jacques the Jackalope tells more here: https://www.eff.org/deeplinks/2024/05/m-jackalope

It sounds like the Librem 5 is making good progress in its performance. I am also seeing pictures of bluetooth from @todd, and gaming videos by @dos

Pretty soon we're going to have #gnulinux phones available, small handheld Linux computers!
