It’s not wrong, but I don’t regard Lemmy.ml as being problematic enough to defederate from. Their moderation practices are questionable and their user base is annoying but it’s otherwise generally tolerable. People can block the instance if they don’t want to see content from it.
There’s too much content on lemmy.ml to defederate. We’d lose like a quarter of all the content.
I thought the Oregon Trail was a pretty standard part of US history curriculum.
Did any distro give concrete reasons for why they have actively chosen not to package it, or perhaps they just haven’t given it much thought yet?
This is not what I would consider a “political reason”. A political reason would be something like refusing to package it because of what political party Howard supports.
There is plenty of software you’ll find in these repositories that aren’t under the GPL. CMake uses BSD, the Apache web server uses the eponymous Apache license, LibreOffice and Firefox use MPL, Godot and Bitcoin Core use the MIT license, and I’m sure there are plenty of other software licenses that I haven’t thought of yet.
If the set of all strings of composite length is a regular language, you can use that to prove the set of all strings of prime length are also a regular language.
But it’s also easy to prove that the set of language of strings of prime length is not regular, and thus the language of strings of composite length also can’t be regular.
You got downvoted here but you’re absolutely right. It’s easy to prove that the set of strings with prime length is not a regular language using the pumping lemma for regular languages. And in typical StackExchange fashion, someone’s already done it.
Here’s their proof.
Claim 1: The language consisting of the character 1 repeated a prime number of times is not regular.
A further argument to justify your claim—
Claim 2: If the language described in Claim 1 is not regular, then the language consisting of the character 1 repeated a composite number of times is not regular.
Proof: Suppose the language described in Claim 2 is regular if the language described in Claim 1 is not. Then there must exist a finite-state automaton A that recognises it. If we create a new finite-state automaton B which (1) checks whether the string has length 1 and rejects it, and (2) then passes the string to automaton A and rejects when automaton A accepts and accepts when automaton A rejects, then we can see that automaton B accepts the set of all strings of non-composite length that are not of length 1, i.e. the set of all strings of prime length. But since the language consisting of all strings of prime length is non-regular, there cannot exist such an automaton. Therefore, the assumption that the language described in Claim 2 being regular is false.

“at least 2 characters repeated [at least] twice” implies the string’s length is divisible by a number greater than 1.
Yeah but it’s just so tempting… It validates so many inputs so easily…
They said—
A line with exactly 0 or 1 characters, or a line with a sequence of 1 or 3 or more characters, repeated at least twice
Note—
…or a line with a sequence of 1 or 3 or more characters, repeated at least twice
It should be—
…or a line with a sequence of 2 or more characters, repeated at least twice
The regex in the post will match “abab”. Their original description (line 2 of this comment) will not match “abab”.
It’s a line with a sequence of two or more characters repeated at least twice.
Yes, they’re similar, but from what I’ve heard, most UK building societies are basically the same as or worse than banks in terms of fees, rates, and service quality. In the US, most credit unions will absolutely spank the big banks on at least two of those, if not all three.
Oops, I didn’t see that. My bad. Guess I made a fool of myself here.
I will start. I’m in the United States.
Credit unions! Nearly half of all Americans are credit union members. They don’t seem to be popular in Europe and Asia. A credit union is a not-for-profit co-operative financial institution that essentially provides all the same services as a bank, except it’s run as a democratic institution with directors elected by the customers instead of as a profit maximisation machine for shareholders.
It didn’t say “e-book” when I originally wrote the reply
You can donate books to the library, you know. They’re always looking for more copies of popular books and what they don’t add to their collection, they’ll resell them and use the money for more books.
Paper books aren’t “waste” by any means as they are easily recycled.
Most authors I’ve heard from (through their Internet posts) don’t mind libraries, but they’d rather you enjoy their books legitimately than pirate.
Student loans are collected by contracted third-party loan servicing organisations, not the Government.
If you don’t pay, the servicer can initiate legal proceedings against you on their own regardless of what’s happening within the Education Department.
