13:04:18 <oklofok> what's your favorite number (modulo 7)?
13:05:56 <Deewiant> 5
13:06:19 <oklofok> niiice
13:06:29 <fizzie> What's your favourite colour (modulo three)?
13:06:45 <oklofok> that's a very weird question, fizzie.
13:07:03 <fizzie> I had trouble deciding between "modulo three" and "modulo green" there.
13:07:16 <Deewiant> If I take it as an RGBA quadruple and interpret it as a single 32-bit number modulo three, I get black
13:07:59 <oklofok> well i'd say black is my favorite color anyway, anything else needs the right hue to look nice
13:08:40 <oklofok> wait don't you also get invisible black?
13:08:47 <oklofok> or which is transparent
13:10:16 <fizzie> Invisible colours are my favourite kind of colours.
13:10:46 <oklofok> you like letting other's choose
13:10:49 <oklofok> others
13:10:52 <Deewiant> If modulo green is modulo 0x00ff00ff, I get 0x004b384a which is some kind of semitransparent turquoise
13:13:51 <oklofok> so what's the original
13:14:33 <oklofok> modulo white
13:14:46 <fizzie> #4b0082? That would give a non-transparent color.
13:14:54 <fizzie> And it looks a bit Deewianty maybe.
13:15:17 <oklofok> no i'm pretty sure Deewiant would want some red in there
13:15:31 <fizzie> That has 0x4b blobs of red.
13:15:42 <fizzie> By #4b0082 I mean 0x4b0082ff, of course.
13:15:44 <Deewiant> Blobs?
13:15:50 <oklofok> oh right lol
13:16:00 <oklofok> yes, that sounds Deewianty
13:16:11 <fizzie> Yes, you measure them as blobs. #ffffff has 768 blobs; that's all you can fit in one pixel.
13:16:31 <Deewiant> Okay; that's good to know
13:17:08 * oklofok believes
13:17:36 <oklofok> http://www.answers.com/topic/blob-visual-system
13:18:11 <Deewiant> Interblobs tell the difference between #ffffff and #ɟɟɟɟɟɟ
13:18:54 <oklofok> are those f's turned upside down or somethign?
13:18:56 <oklofok> *something
13:19:36 <oklofok> what does it mean they are sensitive to orientation
13:20:01 <oklofok> like only light from a certain angle hits them
13:28:28 <Asztal> That seems unlikely, since they're in the visual cortex

18:10:47 <AnMaster> ais523, fsck not installed
18:10:48 <AnMaster> huh
18:10:56 <ais523> of course, it is
18:11:03 <AnMaster> ais523, since when does ubuntu use first tire support staff
18:11:03 <AnMaster> XD
18:11:04 <ais523> as far as I can tell, that's a completely bogus comment from the developer
18:11:36 <AnMaster> ais523, did you try a different fsck version from a livecd?
18:11:42 <ais523> no
18:11:47 <ais523> too busy with other things
18:11:47 <AnMaster> why not?
18:11:51 <AnMaster> ah
18:12:34 <fizzie> The "first tire" typo immediately made me think of a Ubuntu supportperson balancing on a unicycle.
18:12:50 <oerjan> unibuntu
18:13:11 <AnMaster> fizzie, eh, tier*
18:16:33 <fizzie> "Unibuntu -- it's only got one wheel group member." That's the motto.
18:17:18 <AnMaster> fizzie, only root then?
18:17:54 <AnMaster> huh there is no wheel in /etc/groups on januty?
18:18:03 <ais523> no
18:18:06 <ais523> there's an "admin" group
18:18:12 <ais523> which is the group of people allowed to sudo, which comes to much the same thing
18:18:23 <ais523> as root doesn't actually have a password, a wheel group would be kind-of pointless
18:18:23 <AnMaster> ais523, "wheel" is *traditional*
18:18:28 <AnMaster> no idea why, but it is
18:18:47 <ais523> AnMaster: GNU su doesn't support wheel, because Stallman thought it was unfair for people to be unable to get root if they guessed the root password
18:18:58 <AnMaster> XD
18:20:49 <AnMaster> ais523, also just do: chown root:wheel /bin/su && chmod 4710 /bin/su
18:20:59 <AnMaster> (unless I misremember mode needed for suid)
18:21:17 <ais523> chmod u+t,g+x,o-x
18:21:33 <AnMaster> ais523, that assumes the write/read perm is sane before
18:21:41 <AnMaster> also why allow other people to read it?
18:21:54 <AnMaster> you don't actually need +r for group/others for suid binaries
18:21:55 <AnMaster> iirc
18:22:17 <ais523> AnMaster: agreed
18:22:25 <AnMaster> on the other hand
18:22:26 <AnMaster> # ls -l /usr/bin/sudo
18:22:26 <AnMaster> ---s--x--x 2 root root 143400 Jun 17 17:52 /usr/bin/sudo
18:22:29 <ais523> but why not allow people to read it, given that GNU su binaries are easy enough to come by
18:22:29 <AnMaster> is rather unusual
18:22:46 <ais523> also, those perms look fine to me
18:22:50 <AnMaster> ais523, yeah they are
18:22:57 <AnMaster> but still, that means owner can't read it?
18:23:35 <ais523> root can read anything
18:23:55 <AnMaster> welll yes
18:24:13 <AnMaster> ais523, btw for fsck, did you try running it manually at all?
18:24:29 <ais523> no
18:24:31 <AnMaster> say, from init=/bin/busybox style of thing
18:24:38 <AnMaster> ais523, might be worth a try
18:24:47 <AnMaster> livecd is best of course
18:28:36 <AnMaster> ais523, I think the person in question did not read the bug properly
18:28:38 <AnMaster> *shrug*
18:28:50 <AnMaster> hopefully someone else will bounce it back to the right thing
18:28:52 <ais523> only real explanation
18:29:32 <AnMaster> ais523, otherwise you can try to change distro of course. This sort of thing generally doesn't happen with gentoo for example
18:29:43 <AnMaster> actually, bug reports tends to be responded to quickly with gentoo
18:29:52 <AnMaster> not *fixed* quickly always of course
18:29:57 <AnMaster> but response is fast
18:36:52 <AnMaster> ais523, what bug reporting tool btw?

21:01:27 <ais523> yay, finally got this FPGA evaluation board working
21:01:27 <ais523> it's running a simple Verilog program that counts up to 2^32 repeatedly
21:01:31 <ais523> showing the top four bits on LEDs
21:11:09 <AnMaster> ais523, how long does it take to count to 2^32?
21:11:27 <AnMaster> seconds? minutes?
21:11:39 <ais523> it was a few seconds to count to 2^28
21:11:46 <ais523> but I was running it from a relatively slow clock
21:11:53 <AnMaster> ah
21:12:02 <AnMaster> ais523, 2^32 is quite a bit bigger than 2^28 however
21:12:09 <ais523> no, just 16 times bigger
21:12:20 <AnMaster> ais523, well, I think that is quite a bit
21:12:35 <ais523> I mentioned 2^28 as it was the lowest observable number
21:12:42 <AnMaster> ais523, hm?
21:12:45 <fizzie> Oh, it's more than a bit; something like four bits.
21:12:55 <AnMaster> fizzie, augh
21:13:53 <AnMaster> ais523, shouldn't a hello world be more.... traditional?
21:13:55 <ais523> four bits, and I had them all connected to LEDs
21:13:56 <AnMaster> using a LCD maybe
21:14:08 <ais523> AnMaster: traditional hello-world equivalent in embedded systems is flashing one LED
21:14:11 <ais523> and I was flashing four of them
21:14:15 <AnMaster> heh
21:14:59 <AnMaster> ais523, what about using 7-(or more)-segment displays?
21:15:14 <fizzie> The TI DSP devboard had four leds too; we had those flashing in a KITT-from-Knight-Rider-y sort of pattern, with the sweep speed controllable with one of the four sliders we had in the "remote control" UI for the project.
21:15:20 <ais523> there's an LCD on the board, but not seven-segment-displays
21:15:29 <ais523> and there's about 12 LEDs on the board, but I only connected four of them
21:15:42 <AnMaster> ais523, an LCD would work
21:15:46 <AnMaster> even better maybe
21:15:55 <ais523> yes, if the docs said which pins on the board it was connected to
21:15:57 <ais523> but they don't
21:16:05 <AnMaster> ais523, that's... weird?
21:16:16 <AnMaster> ais523, bad docs?
21:16:33 <ais523> suspiciously bad; in fact, I'd say deliberately bad
21:16:40 <AnMaster> ais523, huh?
21:16:41 <ais523> they want you to buy a complicated configuration program
21:16:51 <ais523> that does all the connection for you so you don't have to look at pinouts
21:17:06 <AnMaster> ais523, oh I see. Why not call them and ask for pinout instead and see what they say?
21:17:18 <ais523> because they don't accept queries from students
21:17:19 <AnMaster> oh and... how hard would it be to reverse engineer it?
21:17:22 <fizzie> II think we might've had some sort of "flicker the leds when it gets a parameter update from the remote control" feature, so in that sense the leds weren't completely useless.
21:17:27 <ais523> I actually thought of reverse-engineering
21:17:40 <AnMaster> ais523, talk to a non-student about this? teacher or whatever
21:17:44 <ais523> but it would be kind-of hard
21:18:12 <ais523> my professor's trying to find out the pinout at the moment, apparently
21:18:12 <AnMaster> ah
21:18:36 <AnMaster> ais523, why would it be hard? could something break?
21:18:51 <ais523> partly because there are thousands of pins, connected to all sorts of thigns
21:18:57 <AnMaster> heh
21:18:58 <ais523> and if you send output to an input pin, bad things happen
21:19:08 <AnMaster> ais523, oh right
21:19:14 <AnMaster> ais523, the leds were documented?
21:19:31 <ais523> yes
21:19:34 <AnMaster> heh
21:19:50 <ais523> which is another reason I'm suspicious, btw
21:21:40 <fizzie> Hardware's like that; stick to software, and you'll never have to... uh, worry about... bad documentation... wait, I don't think that's actually true.
21:22:31 <fizzie> Well, at least with software usually you can have a backup if you make smoke come out of it when experimenting.

22:02:05 <AnMaster> ah
22:02:46 <AnMaster> ais523, how is donations to universities suspicious?
22:02:57 <ais523> in that it's clearly an advertising ploy
22:03:08 <ais523> to get us using their products when we leave, rather than a competitor's
22:03:12 <ais523> because we're more used to them
22:03:20 <AnMaster> ah right
22:03:29 <ais523> if we can't get the peripherals working, though, it's possible that ploy will backfire :)
22:03:39 <AnMaster> indeed
22:06:35 <AnMaster> ais523, hm I guess MSDNAA is the same basic idea?
22:06:40 <ais523> yes
22:08:10 <AnMaster> ais523, IMO MSDNAA backfires *badly*
22:08:26 <ais523> in what way? I have an MSDNAA subscription in theory but I've never used it
22:08:32 <ais523> or even asked for a password for it
22:08:54 <AnMaster> ais523, because I learnt that Windows 7 need like 7 GB hd space for a minimal clean install
22:09:00 <ais523> ouch, really?
22:09:06 <AnMaster> ais523, well it was x64
22:09:13 <AnMaster> so I guess 32-bit is a bit less
22:09:15 <AnMaster> but not much

22:10:43 <AnMaster> hah
22:10:57 <AnMaster> ais523, xp x64 needs around 2.5 GB iirc
22:11:00 <AnMaster> way more reasonable
22:11:00 <ais523> I have Kolourpaint installed as a better-than-paint image editor
22:11:09 <AnMaster> ais523, krita is good I heard
22:11:19 <ais523> but it's KDE, and I'm not sure if there's a similarly-featured Gnome program
22:11:22 <AnMaster> kolourpaint is useless to me
22:11:30 <ais523> kolourpaint is just paint with more features
22:11:34 <ais523> but not many more
22:11:55 <AnMaster> ais523, what about krita. It supports non-RGB, which gimp still doesn't
22:12:09 <AnMaster> however it lacks many of the useful photo editing features of gimp
22:12:22 <AnMaster> seems more intended for artists that draw stuff
22:12:39 <AnMaster> I keep imagining someone using a wacom pad or such with it
22:16:17 <AnMaster> ais523, oh and the downloader app sucks
22:16:18 <AnMaster> for MSDNAA
22:16:32 <ais523> does it run under Linux?
22:16:38 <AnMaster> it uses CRC at the end it says, yet usually results in bad downloads
22:16:39 <AnMaster> ais523, no
22:17:07 <AnMaster> ais523, wine said something about missing MSIE activex embedding galore thingy
22:17:14 <ais523> heh
22:17:29 <AnMaster> ais523, well I don't think the word "galore" was there

22:18:40 <AnMaster> that doesn't work out

22:24:33 <AnMaster> ais523, night. I have an early day tomorrow
22:25:05 <AnMaster> (oh that was probably a Swedishism too)
22:25:15 <ais523> nope, same idiom's used in English
22:25:20 <ais523> well, almost
22:25:27 <AnMaster> oh?
22:25:29 <ais523> something you've said there is subtly different from what we say here, but I'm not entirely sure what
22:25:47 <AnMaster> ais523, I think it may be "early morning" in Swedish
22:25:52 <AnMaster> well
22:25:58 <AnMaster> "tidig morgon" rather
22:25:58 <ais523> bye anyway
22:26:02 <AnMaster> but yeah
22:26:03 <AnMaster> night
