A robot used in research. This one is a whole body with arms and legs. One comment I heard is that device is a little noisy with motors and audio quality is not great. Also, check out the price!

A web based tool, free to use, designed for education and teaching. Not heavy duty for professional use.

A standardized way to collect dta about intrinsic motivation. If you are looking into the motivation before and after an intevention, this might be a useful tool.

Very comprehensive collection of notes useful robotics. But caveat - I haven't quality controlled it. It looks good though.

Udev Rules are a nightmare. Usually you don't have to deal with them but if you do, prepare to go deep into bit snd byte land. I have various guides here to help.

Interesting. There are more and more of these coming out. For now I doubt they work very well, in practice. However the trend is clear and they will get better and better. Are our jobs at risk? Only if we don’t learn how to use these tools to up our game. A graphic designer or photographer that…

Someone implemented a really nice simple GUI with this. I was impressed. I had not heard of it before and maybe neither had you.

A super comprehensive introduction to GPS, with more detail than I have seen elsewhere. Also based on the second paragraph it seems to be quite up to date (2023)

Julia Evans continues with her tour the force in depth explainers about how git actually works.

A great step by step introduction to ASYNCIO in Python for cleaner concurrency and synchronization.

This is one of my favorite, super-simple, guides to creating nice designs. These elementary rules-of thumb go a long way to making professional looking designs - or just avoiding the most obvious design mistakes. And of course, because design is subjective, you may have very different opinions.

Nice article but I disagree with the conclusion. I have found that you need to combine the two and go back and forth. There is no single way. By the way, notice that if you believe in TDD, that approach generally starts bottom up (UNITs are at the bottom.) so whatever design comes out of that…

I’m not recommending this as I have not tried it. But it could be something useful for my project and yours.

More than you ever wanted to know about how the PiCamera works. As usual, things are more complex than you expect when you get into them!

Very useful tool to work with camera parameters. I don’t even know what v4l2 is, but all kinds of camera parameters can be displayed and changed.

Really Important package to allow you to calibrate the camera. It is here because I lost it for a while (forgot the name) and now I found it again!

Downloadable textbook about Mining of Massive Datasets by Jure Leskovec, Anand Rajaraman, Jeff Ullman.

This is super useful for rails apps. Will it work for other frameworks like Sinatra? I haven’t tried this yet but it looks promising.

Ok this is also for me to remember important links! Here is the source code for the opencv ROS support for the camera. I now prefer it over Raspicam.

This looks quite interesting. I’ve been using calendly extensively for a few years. But it is kind of expensive. Is this a viable alternative?
