Actually, it can't save at all if there are spaces in the filename

We certainly wouldn't want to load from or save to a directory named "My Documents" or anything
00:13
<@Azash>
Can you escape them?
00:13
<&McMartin>
Doesn't appear to work
00:13
<&McMartin>
And when typing in the minibuffer you aren't supposed to have to
00:13
<@Azash>
Hm
00:13
< RichyB>
I would be surprised by that, given that I've saved to files in directories with names like "C:\program files (x86)\steam\steamapps\common\..."
00:14
<&McMartin>
RichyB: Yeah, that didn't work for shit
00:14
<&McMartin>
It escaped the quotation marks and then decided that it was an invalid drive
00:14
< RichyB>
Grrr.
00:14
<&McMartin>
It will tab-complete "My Documents" and then say "no match" when you try to go further from there.

Isn't the actual directory name "Documents", and Windows just presents it as "My Documents" when you view it in Explorer?
00:42
<&McMartin>
Derakon: Not according to its own directory scanners.
00:43
<&Derakon>
Hm.
00:43

Maybe it's doing some kind of symlink shenanigans then.

<ErikMesoy> How do I force-expand a bit.ly shortened URL? It points to a PDF and I want to know where the PDF is. <-- if you need a more pragmatic way, just send a HEAD request instead of GET.
03:18
< Vorntastic>
You should be able to set bit.ly to show the expanded url instead of redirecting immediately.
03:19
< [R]>
<ErikMesoy> At least it seems like one is hooking into the WM rightly, and the other wrongly. <-- from my experience it isn't really "hooking in" so much as "what was the resolution when I started? Oh, that? Great, okay, I want this one. I got it? Good. Oh, I'm closing/minimixing now? I want <remembered original resolution> in response to that event. Thanks."

Some programs do it wrong, and trigger resize events on other windows in the process.

04:49 * Thalass idly ponders how to use python to turn ultrasonic distance measurements into a 'map' of surroundings, and use odometry to navigate within that map.

05:01 celticminstrel is now known as celmin|bed

< Thalass>
The trick would be to store the rho/theta (or convert that into x/y) information in such a way that you can synchronise it with orientation and position changes detected with the odometer thingies on the wheels. I figure using both would mean you can scan with the ultrasonic sensor in a slower, more detailed way without missing too much.

< xybre>
If you can get defined distance and rotation (vector) from origin you can place a marker there, repeat at high frequency and then use a process to try to draw smooth lines between the points. But it depends on the kind of input you're getting from the detector.

<@Alek>
"He's completely old-school. Respect. Writes his smilies with a dash."
05:45
<&McMartin>
Ouch
05:46
< thalass|werk>
xybre: Most likely a simple number for distance, and i suppose using the servo position command as the vector input - though you'd have to wait for it to stabilise before you save the data
05:47
< thalass|werk>
I might put something together with picaxe, talking to the computer over serial port, to try it out before my pi gets here
05:48
< xybre>
thalass|werk: You'll end up with a 2D nethack map of the surroundings :)
05:48
< thalass|werk>
I was picturing something like Doom's map, yes. :P
05:50
< thalass|werk>
First step is to get the robot to map and remember its surroundings. The second step is to get it to save that file for later use, and then get it to figure out where it is on startup - comparing it's current surroundings with what it knows from the saved map. Third would be to get it to do it's thing, then return to a known spot for charging after. Also: Tolerate minor changes in the map, like chairs shifting or humans not standing
05:50
< thalass|werk>
in the same place every time.
05:50
<@Alek>
what does NaN stand for, again?

Not a Number
05:50

ah yes

< thalass|werk>
(using python because it's the only hammer i have, and this problem looks like a nail to me)
05:51

(+/0) + = +, but (+/-0) + = NaN

Alek: +inf - inf = NaN; +inf / +finite = +inf; +inf/-finite = -inf
07:19
< Syka>
how is inf - inf not 0?
07:20
<~Vornicus>
Because inf + (anything other than -inf) = inf; move the first inf to the right side and you get (anything other than -inf) = inf - inf
07:21 Stalker [Z@Nightstar-b920a19c.cust.comxnet.dk] has joined #code
07:21
<~Vornicus>
So it could be /anything/, and therefore it's NaN
07:23
<&McMartin>
Note also that depending on how you go tthe infs, inf/inf can be any individual number, or it can also be NaN.
07:23
<&McMartin>
limit as n goes to infinity of 2n / n, for instance.
07:24
<&McMartin>
That's 2.
07:33
<~Vornicus>
If it can be any individual number, then it's counted as NaN
07:34 * Syka 's mind explodes
07:34 * Syka hides in the rational world of normal numbers :(
07:34
<&McMartin>
Limits: still less obnoxious than floating point :/
07:35
<~Vornicus>
never mind that "normal numbers" has a special meaning; it is in particular numbers which have every finite sequence of numbers in them.
07:37
< Syka>
man, there are so many interesting things I could do with a custom email server
07:38 * Syka wants to work on it, but has work projects first :(
07:38
< Syka>
for example, selective-secrecy email inboxes
07:39
< Syka>
you can access it over IMAP from anywhere, but you can mark folders as inaccessible except from certain IPs
07:39
< Syka>
so your mobile phone could be hooked up by IMAP, but only get your inbox

and if an IP from the NSA opens your email folders, all the email bodies are interspersed with UNDER GOD WE TRUST, PRAISE AMERICA

ToxicFrog, git collaborator extraordinare
14:25
<&ToxicFrog>
There's no one answer, though, it depends on how your team uses it (e.g. central gitolite repo, github, kernel developer anarchy, etc)
14:25
< Syka_>
'kernel developer anarchy' that's a weird way of pronouncing linuscracy
14:26
<&ToxicFrog>
It's become something of a catchphrase in this channel!
14:27
<~Vornicus>
Well, it is -- as mentioned before -- kind of crazy on the other end
14:28
<~Vornicus>
So currently it's "everybody else is writing directly to the semi-live directory and I'm actually being sane"
14:29
<&ToxicFrog>
Aah yes.
14:29
<~Vornicus>
But, because they're doing that, when I want to add in my changes, it's not the way I've been doing, which is to say, change, commit, push, because, well, shit's happened over there.
14:30
<&ToxicFrog>
So this is less "how to use git when working with other people", or even "how to use git when working with other people who use a different version control system", but "how to use git when working with other people who are goddamn crazy"
14:31
<&ToxicFrog>
There is no canonical version control system you can get their commits from, people just copy stuff directly into prod?
14:31
<~Vornicus>
Technically it's dev
14:31
<&ToxicFrog>
that's slightly less bad but only slightly
14:31
<~Vornicus>
What I /can/ do is go in there and commit all their changes as myself.
14:31
<&ToxicFrog>
Right.
14:32
<&ToxicFrog>
My recommendation would be to maintain a "dev" branch; commit their changes yourself, merge with your work, then push that.
14:33
<&ToxicFrog>
That way you don't clobber their work and even some modicum of a history for it.
14:37
<~Vornicus>
Okay, let me see if I can get this right. 1. commit dev's work to a branch, doing this as often as sensible because the moment they fuck something up I can superhero all up in there. 2. commit my stuff to my own branch. 3. git merge the two branches when I need to get something onto live.
14:46
<~Vornicus>
Right. This I can do. Thank you!
