Gotham Chess is entertaining, but Levy's not doing so much beginner content these days. I like Eric Rosen's "speedrun" series. He's got an authorised speedrun account on chess.com (meaning that his opponents do not

What is "world" in this context? I assume it's all users on that machine, but the term "store" feels like it might be online?

I'm imagining a scene in a Bond movie where 007 casually bypasses encryption by mashing the enter key. Actually I don't think even movie studios would think that looks realistic.

You can run multiple executors at different interrupt priority levels (with multiple tasks per executor), which allows tasks on the higher priority executor to interrupt other tasks. Here's an example https://github.com&#x2F

I just watched a Ted talk by Sal Kahn (founder of Kahn academy) where he talks about giving their chat bot an internal monologue. It's light on details but might be a starting point. https://youtu.be/hJP5GqnTrNo?t=735

Surface mount soldering is not too hard. I can't view the BoM on mobile, but from the photos the soldering looks achievable for someone with experience soldering through hole. Take a look at the document here https://github.

I would argue it also lowers the barrier to entry for experimenting with new techniques for generating/processing audio. For example, you could pretty quickly create a page that has touch controls for adjusting parameters, uses a neura

I have the original handheld console Pocket Chip[1] which came with PICO-8. My son is now enjoying it as a learning tool for game development, but it's quite slow to boot up and there are no more software updates Next Thing Co. is no l

I've worked a little with commercial eye tracking software. It's typically paired with an infrared sensitive camera and IR lighting because the pupil stands out more against the iris under IR light. It also benefits from a rectili

Unrelated to javascript, but in the robotics industry there is a trend towards Behaviour Trees. https://www.behaviortree.dev/ is a C++ library that was originally designed for controlling robots via ROS, but it appears to b

These are really great as a router/firewall. Multiple Ethernet ports, a low power (fanless) x86-64, battery backup for RTC (which is missing from a lot of SBCs), good connectivity for storage and wifi modules. I do wish it had video ou

Great looking site, well done. Are the chords all hand coded? What determines which notes are included? For example some G-shape chords (using CAGED system) are missing the low E & A strings, while some are missing the high E. It would

This is a cool project. I wonder swapping the laser for a sharpie/pen plotter would make it more accessible to a wider audience? I imagine that you could cut it accurately enough if the designs were drawn onto the fabric?

I carry a folding bluetooth keyboard when I'm on call and just use my phone to SSH to another system. It's a great setup in a pinch. Decent battery life, built in 4G and close to a full sized keyboard which is much easier for typi

You might be better off with directional wifi antennas if appropriate for your application.

This reminds me of the method of calculating Fourier transform by refracting light through a prism and reading off the different frequencies. You get the "calculation" for free.

We use a Supercapacitor UPS hat to supply enough power for a controlled shutdown due to concerns over SD card corruption (you get around 1 minute). It's been reliable on systems that regularly lose power over a period of around 5 years

I think to say they had any colour at all in my mind might be pushing it. The way I imagine it is more like the concept of a ball and table. The imagery, while clear to me, seems fuzzy somehow if I try to resolve details. Yet I know the obj

I have aphantasia, although to a lesser degree to the author. Like you I can visualise 3d models in my head, but if I try to recall an image of someone it lacks detail. I can "fill in" detail by recalling facts about that person (
