Free LISTSERV (email discussion) hosting

https://gaggle.email/ provides completels free email discussion hosting for up to 1000 members with moderation and a 3 month searchable archive. You can get additional features by purchasing either a 10 cent a month per user or a 15 cent a month per user subscription. But, honestly, I think I can get by with the free plan.

Crostini, the heart of Chrome OS

Chromebooks seem simple but under the hood there’s quite a bit of code that makes it all work. https://chromium.googlesource.com/chromiumos/docs/+/HEAD/crostini_developer_guide.md has an excellent fairly high level diagram of Chrome OS (CrOS). The Termina VM (right, Terminal without the trailing L) is where your “standard” Linux container (known as “penguin”) is started which gives you your full blown Debian environment. But note that at its very heart is a Debian container which starts up everything else. The reference above talks about how to MAKE CrOS.

If you want to learn more about how to USE CrOS and maybe launch your own containers instead of or in addition to penguin, read https://chromium.googlesource.com/chromiumos/docs/+/HEAD/containers_and_vms.md which talks about the mechanics of things

Google is bringing full on KVM to Android 13

Yeah! Now, you’ve gotta wonder how well it’ll perform but someone has already run Windows 11 on their Pixel 6 running the Android 13 preview. Here’s the tweets https://twitter.com/kdrag0n/status/1492754683445669893 and here’s a link to an asrticle that goes into more detail about the KVM implementation https://blog.esper.io/android-dessert-bites-5-virtualization-in-android-13-351789/ if you want more info.

https://www.androidauthority.com/windows-11-android-13-3107906 is the source article with some higher level info

Quantum entganglement and some subtleties

I found this to be a good article discussing and to some extent explaining quantum entanglement. Not only the broad brush explanation that I usually see but some of the more subtle elements like a particle is likely partially entangled with more than one other particle so knowing the state of one may not completely convey the state of the other. https://interestingengineering.com/quantum-entanglement is the article I reference.

Good analogies help understanding and hacking bitcoin with quantum computers

About half way thru the article explains superposition and entanglement using an analogy of spinning coins. It’s an interesting analogy and one that could help folks who don’t understand those concepts. Aside from that, the article is interesting because it discusses hacking bitcoin (or, more generally, a blockchain) and why more qubits are needed as a sort of error correction..

Linux in a browser

Now that you’ve got docker set up on your Mac or Windows box or even on your Linux machine or NAS or chromebook (see https://tonystakeontech.com/2022/02/08/a-cookbook-to-run-docker-on-your-chromebook/), what can you do with it? Well, I could send you over to https://hub.docker.com/search?type=image but that just shows you some of what’s available in the world of docker containers. Instead, how about running Linux in a docker container that you can access locally in your browser? Yeah, I know, it’s a bit funky in that you may already be running Linux, with or without a GUI, but it’s an easy project and even kinda fun.

Head on over to https://tech.davidfield.co.uk/webtops-linux-desktop-in-a-web-browser/ for the cookbook to bring up Webtop (more info at https://docs.linuxserver.io/images/docker-webtop including different base images like XFCE Ubuntu, KDE Alpine, etc). And, BTW, there are quite a few more images available over at linuxserver.io so check them out, too. That link to docs.linuxserver.io lists other images.

A cookbook to run docker on your chromebook

I know, if you’re running Linux on your chromebook then you’re already running a virtual image but until Google releases the code that makes it easier to add images alongside Linux, this is probably the easiest way to run them, albeit in your existing Linux container. https://dvillalobos.github.io/2020/How-to-install-and-run-Docker-on-a-Chromebook/ is a cookbook approach which makes setting it up even easier and you can be up and running docker images in…well, it took me less than 10 minutes (I already had my Linux environment set up on my 11th gen Acer Spin 713)

Quantum state maintained for 5 seconds!

Using a silicon carbide platform. 5 seconds is long enough to send a signal via light to the moon and back or around the earth 40 times. A lot can happen over the Internet in 5 seconds. Perhaps a quantum internet is not so far away? See https://eandt.theiet.org/content/articles/2022/02/five-second-record-set-for-preservation-of-quantum-states/ for details
