@ASCII-only I mostly like that you don't have to import anything to get regexes work, but it's good that there are lots of good features in there, too. I just don't know what many of those features are :D

@Sherlock9 but regex is supposed to be an essential object type

@ASCII-only nods sadly

I guess the Python team just wants a small core of stuff and anything that isn't always essential is kept to other modules

Regexes are cool, but how often do you use them?

ASCII-only

@Sherlock9 depends, if you use string manipulation a lot they are very handy

I suppose Python is more number-focused, so regexes are a lot less important

TùxCräftîñg

proof of the superiority of PCRE: \p

Sherlock9

Or they think that what string manipulation functions that are already attached to the str type is usually sufficient and regex capabilities are more for the crazier substitutions. Lookbehinds and lookaheads and so on.

TùxCräftîñg

(?:\p{L}|_)(?:\p{L}|\d|_)* match a identifier even with unicode in it

but it only works in PCRE

Sherlock9

Ruby has /\p{}/

@ASCII-only Still waiting to hear it. ;)

zyabin101

@VTCAKAVSMoACE >^.^>

ASCII-only

uh, so idk how to securely encrypt stuff well, would scrypt to verify the password + any sufficiently secure encryption algorithm be secure enough?

VTCAKAVSMoACE

@ASCII-only As long as you don't disclose the clear password, yeah. And assuming there's no problems with your encryption algorithm. :P

If you run on Linux-based, just use pgp encryption.

ASCII-only

@VTCAKAVSMoACE I'm using node, so no pgp builtin

VTCAKAVSMoACE

@ASCII-only Hmm, OpenPGP.js exists.

I've actually been working with that a lot recently. >.>

ASCII-only

1:52 PM

@VTCAKAVSMoACE so pgp is better than things like aes?

@VTCAKAVSMoACE wait what why

VTCAKAVSMoACE

@ASCII-only Depends.

PGP is good for encrypting for the purpose of sharing information securely, so, encryption with multiple public keys for distribution and decryption by their respective privkeys.

AES is symmetric cypher, so it's good for one user, period.

@ASCII-only Because I had to use node for decryption recently. ;P

TùxCräftîñg

esolangs.org/wiki/P%E2%80%B2%E2%80%B2

what is the behaviour of (q)?

execute q while i != 0 or while a[i] != a[0]

ASCII-only

@VTCAKAVSMoACE i mean, that's a pretty specific thing to work on, what do you usually use node for?

VTCAKAVSMoACE

@ASCII-only That was my first use of JS, ever.

So.

Yeah.

ASCII-only

Well, I can't say node was my first use, I created a really bad userscript last year and then discovered node

TùxCräftîñg

plz halp

VTCAKAVSMoACE

@TùxCräftîñg wot

Your question?

TùxCräftîñg

^^^^^^^^^^^

VTCAKAVSMoACE

Iterate with q while q != a[0].

Sorry no

ASCII-only

how secure is encryption with aes + plain password?

VTCAKAVSMoACE

var i = q;
while (a[i] != a[0]) {
 a[i];
 i+=q;
}

That's how I interpreted it.

TùxCräftîñg

1:59 PM

VTCAKAVSMoACE

@ASCII-only As secure as the password. :P

Adnan

Why encrypt the password instead of hashing it?

zyabin101

@VTCAKAVSMoACE So if you password open, the whole building will destruct upon you sometime soon? (]:P

@Adnan i mean encrypt with the password

Adnan

@VTCAKAVSMoACE I meant, "if you password open, the message will be hacked sometime soon, right?"

Ah, thanks Dennis - a quick for keyed sort - good :)

orlp

and if I did, I would hope it was for the same thing as I said above (a true sequence, no real relationship with n), otherwise I would disagree with past-me

quartata

Guys I'm on a What-If binge please help

orlp

@quartata All I can recommend is have snacks in range

quartata

@orlp ba dum tss

Dennis

@JonathanAllan þ is table (each element of the left argument with each element of the right argument). Þ is keyed sort. Those look awfully similar... >_<

quartata

@trichoplax I can do that but that seems like it would make the problem worse

@Dennis Ooh Scandinavian letters. I like that :D

trichoplax

@quartata The other trick is to bookmark the page, which makes it slightly easier to force yourself to close the tab

Yeah, just like A finds A and a.

It's an uppercase and a lowercase thorn (I think).

quartata

Jonathan Allan

Thorn (letter)

Thorn or þorn (Þ, þ) is a letter in the Old English, Gothic, Old Norse and modern Icelandic alphabets, as well as some dialects of Middle English. It was also used in medieval Scandinavia, but was later replaced with the digraph th, except in Iceland, where it survives. The letter originated from the rune ᚦ in the Elder Fuþark and was called thorn in the Anglo-Saxon and thorn or thurs (a category of beings in Germanic paganism) in the Scandinavian rune poems. Its reconstructed Proto-Germanic name is Thurisaz. It is pronounced as either a voiceless dental fricative [θ] or the voiced counterpart...

I think I've managed to alternate reading one What-If and fixing one bug though

A compromise

(it's not like what I'm doing is important anyways)

Jonathan Allan
