16:34
< RichardBarrell>
ToxicFrog: why?
16:34
<@ToxicFrog>
Matrices.
16:34
< RichardBarrell>
Implementing encryption and decryption sounds pretty easy. Key generation seems like it might be a pain in the arse.
16:35
< RichardBarrell>
Does that make it a problem by itself? You _have_ access to BLAS and LAPACK.
16:35
< RichardBarrell>
Numpy!
16:37
<@ToxicFrog>
It makes it a problem when you have to do it with nothing but a sheet of paper and a calculator, yes.
16:38
<@ToxicFrog>
Even given the encryption key, calculating the decryption key is a collosal pain in the ass and very fragile
16:56
< RichardBarrell>
By hand. :(
16:57
< RichardBarrell>
AES or Blowfish by hand would've been worse.
17:02
<@ToxicFrog>
True.

<@ToxicFrog>
I kept getting the wrong answer
17:03
<@ToxicFrog>
So I wrote a simple program to do it for me
17:03
<@ToxicFrog>
And it got the same answer
17:03
<@ToxicFrog>
But since the program decrypted the entire message, I could see that it was actually the right answer; the message was just inverted with respect to every other hill cipher we've ever done, so if you decode it columnwise it looks wrong.
17:03
<@ToxicFrog>
Fuck.

22:02 * Derakon eyes one of his coworkers.
22:02
<@Derakon>
She has an NTFS external hard drive, and wants to be able to modify its contents on her OSX computer.
22:02
<@Derakon>
For whatever reason, said computer can mount the drive, but only as read-only.
22:02
<@jerith>
That will be tricky.
22:03
<@McMartin>
Right
22:03
<@McMartin>
She'll probably need a FUSE plugin
22:03 * jerith nods.
22:03
<@McMartin>
My guess is that by default OS X is using older NTFS drivers.
22:03
<@Derakon>
So she SSH's onto a Linux machine, which can mount her OSX box as a network drive, which in turn gets it access to the NTFS drive.
22:03
<@McMartin>
(But this tracks expected behavior on Macs, AIUI)
22:03
<@Derakon>
However, the particular directory she wants to modify has no write permissions for non-owner, and she doesn't have sudo on the Linux box, so she's still out of luck.
22:04
<@McMartin>
Boo.
22:04
<@Derakon>
I'm really not clear on how this could ever work, though, unless network mount bypasses the owning computer's drivers somehow.
22:04
<@Derakon>
But she claims it has in the past.
22:04
<@jerith>
If the machine the drive is plugged into can't write to it, you can't do it across a file share.
22:04
<@McMartin>
Now that you mention it, it might, at that.
22:05
<@jerith>
Unless you export the bloock device and mount that.
22:05
<@jerith>
*block
22:07
<@Derakon>
It's just such a bizarre setup to begin with.
22:08
<@Derakon>
And I don't really get why we have these incompatible hard drive formats anyway.
22:09
<@Derakon>
(Meanwhile, I myself am trying to figure out how py2app managed to grab an incomplete / incorrect numpy which is impossible to import, when the standalone version works just fine...)
22:31 * Derakon builds numpy from source and reinstalls it, thereby fixing the issue.
