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 already here).

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 tricks. I'll try this out! [1] - https:/&#x2F

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 always baffling to me. Why doesn't Jupyter know the r

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. Gravitational waves are the waves in spacetime caused by powe

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 installation process (but with the q5 firmware) would work

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 might give it a shot after your "very easy

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 Macbook Airs. I usually just use LMStudio[1] though - it's

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 distribution of mass in the Moon's interior [0]. Lunar

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 wondered about setting this up for som

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 thinking I should recompute the SG coefficients every time I hit

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 run any new model or fine-tune I hear about.

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 orbits in sight! Now I'm not sure which

> System76 claims 14 hours, and I managed 11 hours in our battery drain test (looping a 1080p video). In real-world use, I frequently eked out over 13 hours. That’s off the charts better than any other Linux laptop I’ve tested recently.

Really cool that the image patches are converted to tokens with just a linear projection instead of a big embedding model! I wonder if that trick will prove viable for other multimodel media like audio.

Are the pictures in that second link from a diffusion model? They look flashy but they don't look like any spacecraft I recognize (and are weirdly asymmetric) and especially don't look like the Starlink satellites SpaceX has launc
