All that work for some miscreant dwarf archeologist with a pick-axe (me) to show up and dig it to hell for a bunch of worthless glass.

Well it turns out you don't even need a backend for this, you get the ~same results getting 404s from regional GCS buckets.

When I was at Google I built https://gcping.com/ for fun to measure latency to each cloud region. I'm honestly surprised it's still up!
Re:Platform-Independent SIMD in Go on Friday September 25, 2026 @11:04AM (#49845681)
https://imjasonh.github.io/playground/palette-swap/ swaps colors in a provided image in wasm, entirely locally in your browser, to benchmark portable SIMD vs non-portable archsimd vs non-SIMD.

Portable SIMD is ~11% slower than non-portable SIMD in this case, but both are ~5x faster than non-SIMD.

> all of these homage shirts are amazing

You can't just say that without sharing those too!

I had Fable one-shot the same demo from the same weights on an iPhone 15 Pro and it decides in ~40ms.
Excellent read, I loved it.

Incidentally, the image seems to be the one the resort uses on their website! https://oanresort.wixsite.com/chuuk

Fun easter egg: the barcode on the cover (the one on the left at least) is for the book's ISBN.

https://www.nola.com/news/hurricane/weather-satellite-goes-1... explains a bit more what this is, and what this means.

> The main NOAA satellite for tracking Atlantic, Gulf Coast hurricanes is out until further notice

> GOES-19 is the main instrument used to identify tropical waves as they strengthen and move over the Atlantic, Caribbean and Gulf of Mexico, providing real-time tracking for forecasting.

I fell down a YouTube hole and watched all of these Derail Valley playthroughs: https://youtu.be/JSONttyEJ4o

Highly recommend if you like having something interesting on in the background.

Relatedly, I vibecoded this a few days ago for fun: https://imjasonh.github.io/kubescheduler-the-game/

It was fun.

Re:In-Browser Container Builds on Wednesday May 27, 2026 @07:39PM (#48302295)
Unfortunately due to the limitations of a valid image ref you can't include creds like that.

You can fork the registry and include your own creds in the backend when it pulls the repo though.

Re:In-Browser Container Builds on Wednesday May 27, 2026 @05:28PM (#48300995)
AFAIK people only begrudgingly pay for Docker and it does way waaay more.

I have yet to receive any commercial interest in any of these tools :)

Re:In-Browser Container Builds on Wednesday May 27, 2026 @05:19PM (#48300852)
You absolutely can just build things and put them on base images without building or pulling the base image at any point. This is a central feature of ko, a simple container build tool for most Go applications: https://ko.build

(I am a maintainer)

Re:In-Browser Container Builds on Wednesday May 27, 2026 @05:17PM (#48300829)
I love seeing folks learn that container images are just fancy tar files and JSON and are therefore buildable by normal tools.

Along my own journey of demystification I made a few toy container image registries over the years that generated and served container images from nothing but the URL itself:

https://ko.kontain.me builds a go application on demand and serves it atop a minimal base image

https://apko.kontain.me builds a base image containing packages listed in the URL, again on demand.

The latest addition, https://git.kontain.me serves an image with the specified git repo already checked out in the image.

None of these should be used for anything serious but they were fun to make and play with. :)

random.kontain.me has been uncharacteristically useful in debugging image caching scenarios.

Re:Gaussian Splat of a Strawberry on Tuesday May 19, 2026 @08:08AM (#48192270)
I'm really interested to see what folks can do with animated Gaussian splats: https://youtu.be/X8yRlA7jqEQ?si=dXeHa03jO7MTBNLA

The filesize of a 3d animated splat is seemingly very small, and the method enables ~arbitrary FPS. But it seems the setup required to record it is still huge and expensive, which limits its usefulness.

Even with that there are some interesting use cases, eg. I'd love to be able to watch concerts this way, and freely move around the stage and crowd from any angle.

Can you create it?
Re:GitHub CLI now collects pseudoanonymous telemetry on Wednesday April 22, 2026 @10:10AM (#47863938)
I did not get that impression from these docs or from a brief look through the gh CLI codebase. Can you point to evidence that makes you believe this is used to collect metrics about requests to other services?
