There are many things wrong with this code, it is hard to know where to even begin. Perhaps strip the socket and network communication code down to a pure console based system so that it at least works, then post that stripped down code to codereview.stackexchange.com for review so it can be improved to the best possible condition, then try creating your UI with the all of the network stuff stubbed out and get that working exactly as you want, then work on removing the stubs and integrating all the pieces. — jewelsea 57 secs ago

I have them on seperate files, working on 1 now So I did not bother including the rest

but it doesn't work

N3buchadnezzar

@Pimgd The pdf should work

The title in the colorboxes are also links ;)

"What's This?"

Pimgd

When I click on the title of the chapter on the "Contents" page, it doesn't jump to that page

N3buchadnezzar

Yeah, I think you have to download the pdf to make that work.

@Pimgd Yeah when I open the PDF in Dropbox the internal links don't work, but if I download it and open it with Edge or Acrobat they do

Pimgd

hmmh

what else

ah

indent level is wrong

> It is straight forward to iterate over the first1000numbers and check for divisibility.

Is indented 1 level too many

N3buchadnezzar

Not decided if I want the code to be flush with the text or indented one extra layer. That is why it is changing a bit.

I think I might go for flush. However that leaves a lot of whitespace on the right.

Pimgd

why are you making this tho

Vogel612

but it also includes keeping calm and maintaining order in the room gently

Phrancis

@Marc-Andre Yay \o/

Vogel612

Hiya @Marc-Andre nice to see you here :)

N3buchadnezzar

My idea was to simply iterate over the palindromes, and checking whether it was prime.

Isn't that a no? What was your idea?

    it.skipto(limit)
    prime = it.previous_prime()
    while prime > 0:
        if isPalindrome(prime):
            return prime
        prime = it.previous_prime()

There's a primesieve class built in? haha

It's probably optimized to use C, otherwise I don't recognize why that would be faster.

@Legato Uses a optimized sieving algorithm which basically is machinecode optimized. Uses a multithreading 235 sieve if I remember correctly.

You can use pip install primesieve if you are on windows. Otherwise sudo is the way to go.

@Legato Sieving primes is really not the way to go though

@N3buchadnezzar Looks like you just recently passed 10K network rep, which means now you get notified of flags in chat

I think It should be much faster generating odd palindromes and checking for primality.

hm

Go backwards, check if palindrome and then check if prime?

@N3buchadnezzar There's probably a way to ignore them though, maybe with a userscript or something, in case they annoy you. In most cases I just ignore them unless I'm familiar with the room they were flagged in

to know which to check first
