We (meaning Daniel McNab in this case) just deleted the GLSL pipeline from piet-gpu, meaning that the WGSL version is the one being developed. That means the end of piet-gpu-hal.

I have very complicated feelings about this. It is the right decision, but there was also a lot special about piet-gpu-hal. The world needs a lightweight, portable runtime for GPU compute.

I have a blog outline on this (https://github.com/raphlinus/raphlinus.github.io/issues/86) but not sure when I'll write it. These days, I'm prioritizing coding.

Found a really nice #opamp to design my #UVC detector for my #bespoke #FPLC project. It has really low input bias current and offset #voltage. It's a bit slow with a slew rate of about 0.35v/us (would take about 14 #microseconds to rise from 0 to 5v) but, for my needs, this is perfect. Also found a better #UVC detector that has high sensitivity around 280nm. Time to draft a #transimpedence amplifier #circuit #PCB!

What happens when you use #autodiff and let your nonsmooth iterative algorithm goes to convergence?

With J. Bolte & E. Pauwels, we show that under a contraction assumption, the derivatives of the algorithm converge linearly!

I will present this work this week at #NEURIPS2022

I can’t with these essays on leaving Twitter—the digital paradise—that fully paper over *years of harassment* organized on the platform (gamergate, yourslip, countless other examples). the company finally addressed harassment several years back (because advertisers were complaining) and progressively tweaked measures but it was by no means flawless by 2022.

#Markdown and #CommonMark are often used interchangeably. The latter refers to the formal specification published in 2014, resolving the syntax ambiguities of the original Markdown spec.
CommonMark and “#pandoc;s Markdown” differ in subtle ways, which is why pandoc has an extra CommonMark parser:

pandoc --from=commonmark

Pretty sleek and very lightweight!

Perhaps at some point I'll write a thread on my deep concerns about our reliance on Google Scholar.

For now, though, why on earth does Google Scholar not let you sort your search results?

You have basically one choice: to see them in "relevance" order—and we're not even told the secret formula used to determine relevance.

You can also sort by date—for papers from the past year only.

It's really crazy that a mature tool supposedly designed to serve the community would be severely limited.

Fun fact: sharing this link on Mastodon caused my server to serve 112,772,802 bytes of data, in 430 requests, over the 60 seconds after I posted it (>7 r/s). Not because humans wanted them, but because of the LinkFetchWorker, which kicks off 1-60 seconds after Mastodon indexes a post (and possibly before it's ever seen by a human).

Every Mastodon instance fetches and stores their own local copy of my 750kb preview image.

(I was inspired by to look by @jwz's post: https://mastodon.social/@jwz/109411593248255294.)

Here's the fix. They pulled two signals horizontally out of the "Group Decode ROM". They went to a NOR gate and an inverter that they added in an empty space. This signal went to another NOR gate, the gate split in two to add another input. This strange layout caught my eye.

I am a qualified disagree. There's a time and place to call out all the great services, protocols and software in the fediverse. That time and place are not the first 5 minutes someone has heard of the network. If people say "Mastodon", just say "Mastodon". And then help them along as the learn more.

Here is another video tour of the moon, featuring hi-res images of several areas of the moon, including the Apollo landing sites imaged at resolutions as high as 25 centimeters per pixel.

The tour also highlights the mineral composition of the Aristarchus plateau, evidence for surface water ice in certain spots near the south pole, and the mapping of gravity in and around the Orientale basin.
