The Nineteenth Byte

@ATaco how? Filenames containing null bytes get truncated at the syscall layer because they're interpreted as a string terminator; slashes will always be taken as path separators as far as I can tell (giving either ENOENT or ENOTDIR); the empty string gives ENOENT; and . or .. give EISDIR

@m90 Doesn't that fail to escape backslashes?

you don't need to escape backslashes inside single quotes

Adám

Oh.

pxeger

single quotes accept any character except more single quotes (and probably not null bytes nor invalid unicode)

@pxeger did you change anything on the site? Because I can't repro it

pxeger

@lyxal nope - weird

if it happens again, let me know

lyxal

I did get a screenshot though

I'll post it in the ATO room

@Adám does that include bash and other shells where ! is the history character, or just regular sh?

Adám

@Neil I didn't know about that either. Whatever you want. Plain POSIX sh is fine.

Neil

ok, just checking that @pxeger's solution is valid (it doesn't work with ! in bash)

hi all

today I am cross that there seems to be no open source linux mail clients that support exchange/oauth2

Neil

11:05 AM

@Anush what do you mean by exchange/oauth2?

Anush

@Neil my work email now uses microsoft exchange

thunderbird supports that//

but it is also insists on MFA which uses oauth2

you have to pay for an odd on to thunderbird to get that

lyxal

Thank you yt ads

Very cool

Neil

@Anush did your work email disable imap, meaning that your only access is via the paid add on which uses other ways to access your account, or is there some other problem?

Anush

@Neil beonex.com/owl

@Neil yes. I would swear at this point

of course they don't care because they all use outlook

Neil

@Anush yeah, they disabled imap, then you have a problem

Anush

11:14 AM

@Neil someone just told me mutt will work!

hello 1970s

Neil

maybe mutt uses ews and that's still enabled

Anush

what is ews?

Neil

but I'm just guessing here

Anush

google says mutt supports oauth2

Neil

ews is an XML-based protocol microsoft invented in the 2000s for third party clients to access exchange

Anush

11:16 AM

which seems to be the important part

got you

hmm.. now I am told evolution will work too. I don't want to use mutt or evolution but I guess I will have to

:(

Neil

what you might find is that you have to manually choose oauth2 in thunderbird account settings after creating the account

Anush

in thunderbird I had to choose to use Owl at one point

Neil

but that's really if it's an oauth2 problem and not an imap problem

Anush

which is the thing I linked above

Neil

please don't spread misinformation about thunderbird not supporting oauth2 if that's not the problem here

Anush

11:19 AM

@Neil do you mean it's the lack of support for ews?

not oauth2?

Neil

thunderbird doesn't support ews, no. I believe evolution does, which is why it would work for you

Anush

ah ok.. But now I see there is Outlook Web Access too

"About this Add-on
Allows you to use your Exchange and Office365 email account using Outlook Web Access (OWA) with Thunderbird."

which is the paid Owl add-on

it's too confusing!

Neil

right I think owl supports owa, ews and activesync, although it defaults to owa

Anush

I thought owa was a browser based web app

Neil

yeah but it's just json requests behind the scenes

Anush

11:23 AM

interesting, thanks

Neil

mind you back in exchange 2010 it was XHRs behind the scenes, they upgraded to JSON in exchange 2013

Anush

good to talk to an expert!

I wonder why thunderbird hasn't implemented ews

Neil

proprietary

Anush

but I mean if evolution has

and apparently mutt?

Neil

is the reason I heard

pxeger

12:13 PM

@Anush why don't you just use Outlook Web?

@pxeger you mean through the web page?

CMC If we consider all arrays of non-negative integers of length 4 whose sum is s in lexicographic order, how can you jump directly to the ith array without iterating over all the arrays before that?
