UmbralRaptor, that fold (1069 lines) is one method.

was just pondering that business over dinner, my problem I encountered was a pretty easy fix, and I think an even more general one could involve catching an exception they are already raising
<SnoopJeDi>
UmbralRaptor, you put too much logic in one place, of course!
<SnoopJeDi>
it's actually even commented fairly well, things like `//bunch injection` indicating the place where you should probably just say `injectParticles()` and break those 83 lines into their own little place

Apparently there have been protests in Novosibirsk this week? Bit strange to hear about that city on NPR, the name is synonymous with Russian accelerator science in my brain
<SnoopJeDi>
I just got a cheap chuckle out of hearing about it on Morning Edition a few days ago
<SnoopJeDi>
I've never heard a peep about the city in a not-accelerator context

UmbralRaptor, those sorts of things never matter until they matter
<SnoopJeDi>
e.g. there was recently a study of questions asked by gender at some astro conference or another. It's easier to wander into sensitive data than you might expect (none of which makes training any less dull)
<UmbralRaptor>
I think that study was in astrobites?
<SnoopJeDi>

Does the confidentiality training extend to things like e.g. datasets withheld for a time for exclusivity reasons?
<SnoopJeDi>
Not really sure which legal buzzwords apply
<UmbralRaptor>
Not that I've seen so far.
<UmbralRaptor>
I think this is one of those things that assumes that all science are life sciences.
<SnoopJeDi>
I guess how I feel about it is that everybody in STEM has such remarkably poor judgement when left to their own devices that training can't hurt

<plutokiller> tomorrow's paper will answer the age old question: does observational bias explain the clustering of distant KBOs? (spoiler: no)

will laugh if the email was legit and from a cousin or something.
<SnoopJeDi>
what the hell is a boolean val--oh you mean 0 or 1
<e_14159>
So, my (Indian) coworker received an email from an Indian prince, who wanted some help to reclaim his inheritance.

Password Rejected!
<UmbralRaptor>
The password you selected was rejected because of the following reason:
<UmbralRaptor>
The following character(s) are not allowed in passwords: @ .
<Iskierka>
... is it going to use your password as an email?
<UmbralRaptor>
Hah!
<UmbralRaptor>
Nah, just a randomly generated password has that.
<SnoopJeDi>
I still haven't seen a policy less sensible than JLab's
<Iskierka>
which is?
<UmbralRaptor>
Hrm. I think this means I have 2 passwords with @s in them now.
<SnoopJeDi>
"1) At least eight non-blank characters. Your password can be longer than eight characters, but not less than. 2) A combination of letters (upper and lower case), numbers, and at least one special characterall. ALL of these conditions must be met within the first eight positions."
<SnoopJeDi>
the length shouldn't matter in any context that isn't 1975 Iskierka :|
<Iskierka>
surely a hash is fixed length regardless of item length though?
<SnoopJeDi>
other than to enforce a sane minimum
<UmbralRaptor>
SnoopJeDi: lolsob
<SnoopJeDi>
yea hash result by definition has a finite size
<SnoopJeDi>
s/finite/fixed/
<Qboid>
SnoopJeDi meant to say: yea hash result by definition has a fixed size
<UmbralRaptor>
As best I'm aware, lots of systems didn't allow >8 characters until circa 2005-2014.
<Iskierka>
therefore if there's a db with old data it doesn't matter that it's 8 characters if it's hashed
<Iskierka>
I also like the implication that hashes *can* be infinite length so long as they're always infinite
<SnoopJeDi>
I don't know enough about formal treatments of hash functions to say if they can or can't be
<whitequark>
SnoopJeDi: "legacy DB somewhere"
<whitequark>
so let me tell you about LanMan hashes
<whitequark>
until windows xp/windows 2003 server inclusive, one of the algorithms that were used by default is the LM hash
<whitequark>
what it did is it split the password into two 7-byte halves (padding or DISCARDING the rest, if any), converting it to uppercase and then hashing every half separately with no salt
<Iskierka>
"The user’s password is converted to uppercase." wat
Wetmelon has joined #kspacademia
<whitequark>
then it transmits that over the network. not as a part of challenge-response auth, just as it is
<Iskierka>
... two separate parts and null-padding means at minimum you can automatically see a short password as all-null will have the same hash in the padded half
<whitequark>
oh, there's no need
<whitequark>
a 2GB rainbow table lets you decode literally any LM hash in a few milliseconds
<whitequark>
not that you couldn't bruteforce it in under a minute anyway
<whitequark>
okay, not literally any, that's not how rainbow tables work.
<whitequark>
figuratively any.
<Iskierka>
literally any that corresponds to an actual input from valid ascii characters?
<whitequark>
no
<whitequark>
rainbow tables are stochastic with a normal distribution (I *think* it's normal)
<kmath>
<whitequark> Twitch Plays Committing To Twitter Codebase
<whitequark>
at least, within their chosen charset, they do not favor any particular combinations, so if you generate one for A-Z then it will miss some A-Z combinations at random
<whitequark>
well, LM hash space is small enough that you could probably generate a rainbow table that covers it completely, but I don't think mine did
<SnoopJeDi>
I should learn more crypto ishouldbuyaboat.jpg

<mcclure111> It seems like taking away the ability to quote-tweet someone while saying something harsh and mocking would make Twitter a much better site
