It might be helpful to elaborate on what permissions mean for directories. As always, this is well explained on the Arch Wiki: https://wiki.archlinux.org/title/File_permissions_and_attributes#Viewing_permissions

The short version is that, when it comes to permissions for directories:

• r is what allows you to see what files are in the directory, for instance by ls directory,
• x is what allows you to operate on the contents of the file, for instance by cat directory/file or by echo something > directory/file,
• w (together with x, in case of directories it is meaningless without x) is what allows you to create new files, delete existing or otherwise modify the directory itself, for instance by cp directory/file directory/new_file.

Note that these are completely separate from the file permissions, which govern the contents of the file. For instance, if I have only x permission for the directory, but I have rw permission for a file of that directory, I can write to the file and read from it. However, I wouldn't be able to remove it. On the other hand, if I have wx permission for a directory and I have no permissions for a file of that directory, I cannot write nor read from the file, but I can remove the file.

In spite of above, you will find all users have rwx permissions for /tmp, but they can only remove their own files. This is due to the sticky bit, which is marked by the output of ls -l having drwxrwxrwt instead of drwxrwxrwx. This means that the system will only allow the other users to rename or remove the file if they actually own it.

A common(ish) usecase for splitting r and x on permissions is when teachers want to collect the work of the students. They might have their home directory permissions set to rwx--x--x to ensure other people can't see their files (and of course they still should make sure that the individual files have the correct permissions). However then they can create a directory /home/teacher/work and set its permissions to rwxrwxrwt. Then for a student, ls /home/teacher will fail, but ls /home/teacher/work and cp my_work.tar.gz /home/teacher/work will succeed.

It seems that Neovim can't see the nvim-lspconfig plugin itself. Have you installed it? If so, how?

I'm super conflicted about this article. The portion on disabilities is great! But then, we see this:

It’s considered an ‘AI-complete’ problem, something that would require computers that are as fully complex as, and functionally equivalent to, human beings. (Which about five minutes ago was precisely what the term ‘artificial intelligence’ meant, but since tech companies managed to dumb down and rebrand ‘AI’ to mean “anything utilizing a machine-learning algorithm”, the resulting terminology vacuum necessitated a new coinage, so now we have to call machine cognition of human-level complexity ‘AGI’, for ‘artificial general intelligence’.)

This is honestly the first part that's outright objectively wrong. A quick look at the Wiki will tell us that the term AGI was already used in 1997, for example. You can't say that it was made up by tech companies about five minutes ago. And the author returns to this “rebranding” later in the article, so you can't just brush this away as a misguided aside; it's just clear that the author does not really know anything about AI, yet is willing to write an article about it. Mix this with the snarky tone, and it just gets very sad.

It's not like that I don't agree with what they say about AI either, and I definitely agree with the big conclusions; it's not like there are no people with a similar opinion that know more about AI (Gary Marcus, for instance), the comparision to disabilities is the novel (to me) part. But I just couldn't share this article with anyone. As I am writing, the top comment on [email protected] is criticizing the same part of the article, except in less nice words. I don't think that the person who wrote that comment will learn anything helpful about disabilities from this article…

It seems that I can't see the link from 0.18.3 instances somehow. Maybe one of these will work: https://math.stackexchange.com/a/18347 https://math.stackexchange.com/a/18347 https://math.stackexchange.com/a/18347

Imagine a soccer ball. The most traditional design consists of white hexagons and black pentagons. If you count them, you will find that there are 12 pentagons and 20 hexagons.

Now imagine you tried to cover the entire Earth in the same way, using similar size hexagons and pentagons (hopefully the rules are intuitive). How many pentagons would be there? Intuitively, you would think that the number of both shapes would be similar, just like on the soccer ball. So, there would be a lot of hexagons and a lot of pentagons. But actually, along with many hexagons, you would still have exactly 12 pentagons, not one less, not one more. This comes from the Euler's formula, and there is a nice sketch of the proof here: https://math.stackexchange.com/a/18347.

Every prime larger than 3 is either of form 6k+1, or 6k+5; the other four possibilities are either divisible by 2 or by 3 (or by both). Now (6k+1)² − 1 = 6k(6k+2) = 12k(3k+1) and at least one of k and 3k+1 must be even. Also (6k+5)² − 1 = (6k+4)(6k+6) = 12(3k+2)(k+1) and at least one of 3k+2 and k+1 must be even.

Isn't this the point though? Like, if you spot that (let's concretize) the trash is starting to overflow, you can either take it out right now which will take you 2 minutes and (hopefully) barely interrupt your day, or you can add it to your list of things to do. And so you get that list of 59 things by ignoring the 2-minute rule, not by applying it.

Honestly I've unironically missed the entirety of the image at first, I went directly to the text. And probably a lot of internet-savvy people would, this kind of image is useless decoration 90% of the time and people are trained to not look at it. Same concept as in that research where they asked people to find the current population number on a webpage and they had a very hard time, despite the value being in big red digits or something equally distinctive.

That's because all the audio drama focused on PulseAudio.

Same for Polish. One funny thing I've noticed is that in one of the examples, the person tries to stay at a hotel, and the price is clearly in the old currency, which has not been used since 1997.
