Scott Manley has a couple of nice videos about wormholes: https://www.youtube.com/watch?v=V7e-1bRpweo https://www.youtube.com/watch?v=PVO8nvb1o2w The second video is about how the first video was made.

Must be nice. I live in Virginia, outside Richmond. For the past 8 years, the power company has failed to provide me with even 3 nines of power availability (that means at least 9 hours of outage every year for the past 8 years. Just had

Thanks for pointing me to that! Definitely some cool ideas in there. Almost seems like some of those ideas could be incorporated into git itself.

I wonder if you could replace the whole github issues feature with just a directory within each git repo named "Issues/". Within that, have another couple directories, "open/", and "closed/". W

I built a model sailboat[1] one time, and if it were for myself and not a gift, I would have named it "Sea Hacker". [1] It was "Schooner Irene" from here: http://www.bearospaceindustries.com/boats2.html

I recently was sent patches for my open source space game[1] that added cascaded shadow mapping[1] and gravitational lensing[3] for black holes, both things that I've wanted for years, but found too difficult to tackle. The patches we

No, you don't commit trash to a public branch, EVER, if you can help it. Your commits are as perfect as you can make them, and that does not mean squashed in a trash compactor. That means one logical idea per commit, compiles and w

For TTS I wonder how this compares to nanotts[1] with the en-GB voice, which is sort of unreasonably good. [1] https://github.com/gmn/nanotts

At my local hackerspace, people sometimes laser cut solder stencils out of transparencies -- the plastic sheets you use with overhead projecters. The trick is to put a piece of paper under the transparency when laser cutting, otherwise the

Disagree. You need small, git bisectable commits. Use stgit to do it and it's nearly effortless.

> Working with lots of changes in parallel on git can be painful. You end up juggling branches and commits, and running scary rebase -i commands that can leave your tree in a half-broken state if you so much as sneeze. I mean, just use s

He's a mathematician, so what he means by "in general", is "in every possible case", or "without exception", so what I think he means is, "not all bugs will be found by code review." I agree it p

Curl Noise[1] is also cool. I've used it to create some gas giant planets for video games [2] though I used opensimplex noise [3] rather than perlin as the base noise, but either will work. [1] https://www.cs.ubc.ca/~r

My own efforts in this area amount to creating the game, Space Nerds in Space[1], which is a LAN game in which everyone gathers in a room with their computers, and each computer acts as one of the stations on the bridge of a starship: navig

The TI99/4a version of the Logo language which has turtle graphics used user defined characters to implement them. There were only (I think) 128 user definable characters, and when the turtle graphics had redefined all of them to crea

Interesting... RP2040 seems like maybe a bit overkill for a zero power badge. I've participated in writing some software for an RP2040 powered badge for the RVASEC conference in Richmond, VA, for several years, and the RP2040 is real

PRs can contain multiple commits. You need something like stgit to make it easy to make a bunch of small commits that appear to be the work of an omniscient genius who knew exactly what they were doing. Try using stgit for awhile, and you

On the "reset"/"stty sane" trick, I also sometimes have found it necessary to press Ctrl-J rather than RETURN at the end of the command.

Something like those switches might be made very cheaply with a 3D printer, possibly a laser cutter, some transparent or semitransparent acrylic sheet, tactile switches and some LEDs. I designed a cheapo replacement for $50 tellite switche

I found it funny that in a sentence that mentions "those who can recognize an LLM’s reveals", a few words later, there's an em-dash. I've often used em-dashes myself, so I find it a bit annoying that use of em-dashes is
