Bored? How about trying a Linux speed run? https://rachelbythebay.com/w/2020/04/11/pengrun/

About 15 years ago, I mused about the idea of having a "desert island machine". This is where I'd put someone in a room with a box that has a couple of hard drives and a working network connection. HD #1 is blank. HD #2 has a few scraps of a (Linux) OS on it: bootloader, kernel, C library and compiler, that sort of thing. There's a network connection of some sort, and that's about it.

Now you see things like people managing to do the original Super Mario Bros game from the 80s in under five minutes, and I do mean people. There are actual humans frobbing plastic controllers doing this! Just dig around on your favorite giant video-streaming site if you need evidence of this happening.

So here's the pitch: Linux speedruns. By that, I don't mean "speedrunning a game on a Linux box" (like emulation, or something). Nope.

DebianDog is very small Debian Live CD shaped to look and act like Puppy Linux. Debian structure and Debian behaviour are untouched and Debian documentation is 100% valid for DebianDog. You have access to all Debian repositories using apt-get or synaptic.

Measuring Mutexes, Spinlocks and how Bad the Linux Scheduler Really is | by Malte Skarupke https://probablydance.com/2019/12/30/measuring-mutexes-spinlocks-and-how-bad-the-linux-scheduler-really-is/

From a tiny observation at work about odd behaviors of spinlocks I spent months trying to find good benchmarks, (still not entirely successful) writing my own spinlocks, mutexes and condition variables and even contributing a patch to the Linux kernel. The main thing I’ll try to answer is to give some more informed guidance on the endless discussion of mutex vs spinlock. Besides that I found that most mutex implementations are really good, that most spinlock implementations are pretty bad, and that the Linux scheduler is OK but far from ideal.

task-spooler - Enqueue task for batch execution http://vicerveza.homeunix.net/~viric/soft/ts/

As the name implies, Task spooler is a Unix batch system that can be used to add the Linux commands to the queue and execute them one after the other in numerical order (ascending order, to be precise). This can be very useful when you have to run a lots of commands, but you don't want to waste time waiting for one command to finish and run the next command. You can queue it all up and Task Spooler will execute them one by one. In the mean time, you can do other activities.

How To Ruin A Perfectly Good Container https://medium.com/@benlaurie_18378/how-to-ruin-a-perfectly-good-container-d33250fca595

The modern world doesn’t look like this at all. All the files on a typical computer belong to a non-expert user (for simplicity I am ignoring shared devices — this doesn’t really undermine the argument as I hope you will see). Indeed, the whole computer typically belongs to a single user. Printers do not need accounting and similarly belong to the same user. The enemy is the software that is running on the machine. Users no longer have a good understanding of the software they run. Software is enormously complex and uses all sorts of resources, many distributed over multiple systems, to accomplish their tasks. And frequently their task is only superficially in service of the user.

In short, the old threat model was untrusted tenants, trusted software, unit of protection is files and devices. The new threat model is trusted tenants, untrusted software, unit of protection is individual data items.

Imagine mobile phones running a desirable operating system, at a reasonable cost. Not running Google or any other “data hungry” services.

And at the same time, mobile phone operating systems where personal and corporate users can install and use the mainstream applications of their choice, if they wish so.

That’s what /e/ is going to provide: attractive mobile phone operating systems with better privacy.
