It's weird to see a new vehicle announced like this that's not an EV. I wonder what it's like launching a gas truck when new battery-powered trucks are looming in the distance (or …

Link to the paper: https://www.nature.com/articles/s41377-025-02119-y From the abstract: > Here, we demonstrate a covert communications method in which photon emission is rapidly e…

This looks great! I've been using ThumbsUp[1] for a similar purpose (creating a gallery of photos I can push S3), but adding album and photo captions required some un-ergonomical t…

I appreciated the Pluto.jl mention! Going from Pluto notebooks that understand data flow to Jupyter notebooks where you have to tell the computer which order to run the cells in is…

Kinda weird - Coolify doesn't come up except in the first and last paragraphs. Seems like the page is incomplete or just mis-titled.

Yup, slight mix-up. Gravity waves are waves in the ocean and atmosphere (or other fluid bodies) where Earth's gravity is the restoring forces that causes wave propagation. Gravitat…

Cool! It looks like the Wansview Q5 has a similar SoC/camera/wireless setup as the Wansview W7, which as an installer guide on the Thingino wiki [1]. I wonder if that same installa…

Thanks! The author's blog is a great find as well - https://www.dm5tt.de/

> The analog ones are easy to play with. You just need a DAC to drive their VCO and then can sample the I/Q pins with an ADC Do you have any reference or notes on how to access the…

Cool! Do you like that approach? I've thought about setting up that exact thing but I wasn't sure how well it would work in practice. Are there any pitfalls you ran into early on? …

I would recommend just trying it out! (as long as you have the disk space for a few models). llama.cpp[0] is pretty easy to download and build and has good support for M-series Mac…

> you can even chroot into foreign CPU architectures, which is a handy thing to have when you mount your phone's eMMC This sounds very interesting! What's the scenario where you'd …

A challenge there is that there are very few stable lunar orbits! High orbits are perturbed by Earth's gravity (3-body problem) and low lunar orbits are perturbed by the lumpy dist…

This sounds like something I'd want to do! Is the idea that you'd have a public domain name like "internal.thatcherc.com" resolve to an internal IP address like 10.0.10.5? I've won…

Yup, my data is nicely gridded so I can use the convolution approach pretty easily. Agreed though - missing data at the edges or in the interior is annoying. For a while I was thin…

I actually have one for this! Last week I had something really specific - a GeoTIFF image where each pixel represents the speed in "x" direction of the ice sheet surface in Antarct…

This is my favorite write up of someone truly building a GPS receiver from scratch: http://www.aholme.co.uk/GPS/Main.htm A real tour de force of DSP - really cool stuff, and well-w…

Sounds like a cool model. I'd love to try it but it seems like they're not releasing it (yet?). I've really gotten spoiled with the recent language models where I can download and …

This list is weirdly not that helpful. `planor`, the planetary orbital calculator, sounds cool, but it's actually "A TUI client for cloud services for aws, vultr, heroku, etc." No …
