The point of these lectures is mostly not to teach how to work with Turing machines, it is to understand the theoretical limits of computers. The Turing machine is just a simple to describe and well-studied tool used to explore that.

For example, are there things there that cannot be computed on a computer, no matter for how long it computes? What about if the computer is able to make guesses along the way, can it compute more? Because of this comic, no — it would only be a lot faster.

Arguably, many programmers can do their job even without knowing any of that. But it certainly helps with seeing the big picture.

So far I have had good experience with kopia. But it is definitly less battle-tested than the other alternatives and I do not use it for too critical stuff yet.

I did not know any of the programs mentioned in the post, but some of them seem really nice. Can someone who thinks aliases are a better solution please explain why they think so and what is their advantage over these projects? Do they have any pitfalls that you are aware of?

I believe that if I use a command sparsely enough, I will forget the created alias name just a few days later than the actual command.

Having a few issues setting up a Matrix instance, could use some guidance.

So I’m in the process of moving my discord server over to matrix. I rented a VPS with 2 cores/2gb of ram for this. What I’m having issues with is media store and federation. I believe I have the media_store configured corrected as I can post images in my own channels, however I get Error 500 while attempting to upload a...

As others said, Synapse can sometimes be very resource-hungry. It might be worth giving a try to Conduit and Dendrite, which are alternative Matrix server implementations and especially Conduit seems to be focused to by lightweight. Although I do not have any personal experience with them and it seems that they are most likely a lot less mature than Synapse at the moment.

Sorry, can’t resist: it would not be 6.5 % of Linux users, it would be 6.5 % overall. That would mean about 54.8 % of Linux users.

Give testdisk a go, see for example this tutorial. It is a terminal utility, so it might take some time to get used to it. But no one can guarantee that it will successfully recover anything, the deleted files stay on the disk only as long as they are not overwritten.

Do you have any idea why the files disappeared after reboot? One thing that comes to mind is that they might have been saved in /tmp, in that case I believe recovery would not be possible.

Regarding to which files you should recover, try all of them and see if you have any luck.

Good luck with recovering the files!

From my understanding, files cannot be directly stored only in a timeshift snapshot – they must be first stored on the disk and only then timeshift can make a backup inside the snapshot. But I have never used timeshift myself, maybe I just completely misunderstand how it works.

Also see pairdrop, it is a snapdrop fork that allows connecting devices on different networks using a numeric code and has other improvements.

By the way, the vim extension for VScode is great, so why not combine both.
