Well-written review, with thus nugget of a quote by Susie Alegre:
When my daughter asked why she couldn’t have an Alexa like her friends, I told her that it is because Alexa steals your dreams and sells them.

This is a neat way to quickly generate a QR-code, for example to transfer text from computer to phone (thanks to Solène Rapenne for the original idea and implementation). On the phone, you'll of course need to use a QR-reader app, such as Binary Eye.
xclip -o -selection clipboard | qrencode -o - -t PNG | feh -g 600x600 -Z -Using this command, whatever is in your clipboard will be encoded to QR and displayed on your monitor. Note that xclip can pull stuff from different clipboards, and in my case the contents were not picked up with -selection default but -selection clipboard did the trick.
Linux (well, really the window managers, so X11 and then, i3, Wayland, etc…) have multiple clipboards. The default ones are the Primary selection one, and the Secondary one. The names are historical accidents, but the “primary” one always has a copy of the last text you selected from anywhere, which can be pasted anywhere by clicking the middle mouse button. You just select some text and that’s it - you don’t have to do anything else and you can then middle-click paste this anywhere. The “secondary” clipboard is the “normal” Cut, Copy, Paste, Ctrl+c, Ctrl+v one.

electricityMap is a live visualization of where your electricity comes from and how much CO2 was emitted to produce it.
The map is open source, and improves weekly thanks to 1700 contributors and counting.
The project has an informative FAQ, a list of its data sources, and a wiki.
An interactive 3D visualization of the stellar neighborhood, including over 100,000 nearby stars.
Pretty cool that this kind of visualisation can be run in the browser (Chromium works fine, so does Chrome). But I'm getting no sound, I suppose that's something to do with my machine.

How do fish swim so quickly? Explained to great effect by professor of applied mathematics Tadashi Tokieda using a bathtub.
Amandine Le Pape (of Element.io) makes some excellent points:
Open APIs are a good first step, but we must eventually have open standard based interoperability.
An open standard is far more secure than open APIs and today’s siloed apps. An open standard can ensure end-to-end encryption (and much more) between competing apps - and be audited independently for the benefit of all.

The infographic plots cities around the world based on the urban population density and per capita transport energy use. North American cities are the least dense with highest energy use, while Asian, African, Latin American and European cities have varying densities, but fall in the category of low energy use per capita.

Let's say you have a tablet or reserve phone without a phone number (i.e., SIM-card) that you would nonetheless like to have Signal installed on. Turns out it's possible.
BUT NOTE THAT SIGNAL WILL DE-REGISTER YOUR ORIGINAL DEVICE ONCE YOU REGISTER THE NEW ONE!
There is still no way to have Signal on more than one device, and you can't link Signal on one device to another device. Too bad, would have been nice, especially with database encrypted at rest (which Molly allows).
- Connect your secondary device to the Internet
- Install Molly-FOSS or Molly or Signal on the secondary device, and initiate Signal's registration process (enter your phone number)
- You will get a code via sms on your primary Signal device
- Enter the code on the secondary device using the numeric keyboard (this worked just fine in my case)
- Enter your Signal PIN
- With that, Molly-FOSS/Molly/Signal should start and show you your groups
While we're at it, why not install Molly or even Molly-FOSS instead of the official Signal app? The benefit of using Molly-FOSS is that we can install it on a device not using Google (the drawback is that push notifications will consume a little more battery).

In this video produced by the American Chemical Society, George Zaidan does a great job presenting a short but fundamental explanation of what an electron is and why that matters (pun intended).
I can really recommend!

Exciting news! No website or similar yet, but here are some news snippets.
This project involves six universities and 50 companies and organisations, and has a budget of 110 MSEK over five years.
Several research themes:
- advanced technology
- building integration
- enhanced PV systems
- land sharing
- planning for large-scale expansion
- and others
Theme 1: advanced technology
Solar cell devices with higher power, lower resource consumption.
For example, perovskite solar cells and tandem cells.

Looks like good fun, and the data that makes up the genealogy is shared under a CC-BY license (bulk data export requires contacting the site admin), but I have found no mention of the license for the code of the website/project.
Their FAQ is very informative.
Gitea is great. So is Codeberg. The ability to share repos, issues, and users across Gitea instances, would be awesome.
Git itself is already federated and decentralised, but there is still a need for federation of the remote repo and its facilities.
The idea of some sort of federation between Gitea instances has been around since 2016.

- sway, drop-in replacement for i3wm on Wayland.
- enlightenment, window manager, compositor and minimal desktop. Not tiling. Supports X11, experimental Wayland support.
There are many more window managers. Add more as I (re)discover them.
