[06:36] ok how can i stop jbd2/sda1-8 from writing to my disk every 10 seconds and waking it up from spindown? [07:21] Morning [07:43] Morning [07:43] \o [07:50] * daubers should stop using libreoffice to plot many thousand datapoint graphs [07:50] * MartijnVdS hands daubers gnuploit [07:50] -i [07:51] MartijnVdS: THats how I would've done it when I was at Uni.... really should sit down with gnuplot and relearn the syntax [07:51] daubers: it's not hard, making pretty pictures using LO would take me longer ;) [07:52] morning all [07:54] Another completely barking US Patent approval http://www.theregister.co.uk/2011/10/25/apple_unlock_patent/ [07:54] You can't really blame the vendors for taking the p*ss but this only really ends up helping lawyers. [07:56] I've got to say, if I had a legal department, there would be a fairly large temptation to just see how amusing a patent I could file [07:56] BigRedS: it has been done [07:57] BigRedS: http://www.google.com/patents?id=OfwkAAAAEBAJ&zoom=4&pg=PA2#v=onepage&q&f=false [07:58] haha [07:58] that's a patent for teasing a cat with a laser pointer? [07:58] it seems to be [07:58] ZOMG! I have infringed that patent! [08:00] don't tell the inventors [08:00] Damn - can I remove that comment from the logs please? [08:00] And that one? And... Ah blast. [08:19] Hmm... really should have used gnu plot [08:21] Oh poo - There's a new DoS tool on the block http://www.h-online.com/security/news/item/New-denial-of-service-tool-knocks-out-encrypting-servers-1366564.html === gord is now known as Guest3890 [08:30] Woot, gnuplot = better++ [08:39] that ssl attack looks pretty bad [08:40] Goooooood morning all! [08:40] yeah AlanBell [08:40] g'morning! [09:00] greetings [09:05] Hmm, I find the "gnu" in gnuplot confusing since it has nothing to do with GNU project and isn't GPL code. [09:06] what licence is gnuplot? bsd? [09:06] I didn't realise that [09:06] Good morning peeps :) [09:06] in its defence, it is not a unix... [09:06] daubers: http://gnuplot.cvs.sourceforge.net/gnuplot/gnuplot/Copyright?view=markup [09:06] daubers, Just reading it now [09:07] It's a little odd [09:07] one of those old "patch" licenses [09:07] It's kind of "segregated GPL" [09:07] heh [09:08] You can't distribute modified versions but you can distribute the means to create them [09:08] And binaries are allowed [09:09] I wonder if it would be stretching the point to distribute modified versions as git clones with the original sources plus patches as branches, pre-merged together [09:09] Unpack, checkout the "patched" branch, sorted [09:11] hmm..open banshee to buy mp3 via amazon. click on a preview to listen to a song and banshee crashes...welcome back to banshee i guess [09:15] I do find that Banshee crashes dead a lot but I wonder if it's more to do with bugs in Unity / Compiz [09:17] (by "a lot" I mean it probably crashes about once a day-ish, or at least often enough that I think "d'oh, Banshee crashed again) [09:17] awilkins: i've had problems forever since banshee. i'm not using unity. [09:18] you run under --debug and report bugs with the log, yes? [09:20] Laney: i use clementine normally but wanted to buy an mp3 album. on this occasion it wasn't a reproducible bug since i've tried again. more of a welcome back crash. [09:21] ok [09:21] moaning might be cathartic but it is usually not conducive to getting things fixed [09:21] might still have a crash log, where are they kept [09:21] yep. , that's why i tried again to reproduce [09:21] possibly ~/.config/banshee-1/log but maybe not if you ran it again [09:22] Any ideas on where I can find Xm.h in 11.10? Previously I think it was in libxprintutils-dev [09:23] http://packages.ubuntu.com/search?searchon=contents&keywords=Xm.h&mode=exactfilename&suite=oneiric&arch=any [09:23] i have created a user on a 10.10 server but unable to ssh in as this new user. keep getting permission denied (publickey) [09:23] any ideas on what is wrong? [09:24] dogmatic69: Have you disabled password login? [09:24] (over ssh) [09:24] !info banshee [09:24] daubers: i believe so [09:24] banshee (source: banshee): Media Management and Playback application. In component main, is optional. Version 2.0.0-2ubuntu2 (natty), package size 1799 kB, installed size 5480 kB [09:24] dogmatic69: Then you'll need to generate a key pair for the new user :) [09:24] daubers: it should be using keys for login [09:25] dogmatic69: Have you generated a key for that new user? [09:25] key's are per user [09:25] can i use the key pair from them? [09:25] Yes, you just need to put the keys in the right place (on server/client) with the correct permissions [09:26] dogmatic69: logging in with ssh -vv will give more info on why it's bombing out [09:26] here is ssh -v http://bin.cakephp.org/view/1772160097 [09:27] the key pair is from his mac that i put in ~/.ssh [09:27] where ~/ is the new users home [09:27] add another v and see if it still complains [09:27] it does [09:27] should give more info [09:27] hold on [09:28] show us ls -la ~/.ssh from the new user account please [09:28] here is -vv http://bin.cakephp.org/view/1690781071 [09:29] stuck it in the link above, just reload [09:30] chmod -R go-rw ~/.ssh [09:31] well, -r [09:31] its like this now -rw------- [09:32] try that? [09:32] if not look in the ssh server's log [09:32] still says permission denied [09:33] where would that log be? done tail -f /var/log/* and tried to connect and nothing happened in the log [09:35] would be in auth.log I'd imagine [09:35] oh... Oct 26 09:29:09 ip-... sshd[26154]: reverse mapping checking getaddrinfo for dsl.in-addr.zen.co.uk [] failed - POSSIBLE BREAK-IN ATTEMPT! [09:36] Is it just me or are a lot of default application associations broken in Oneiric [09:36] does that mean anything... dont think so [09:36] Like I installed FreeMind but it doesn't open .mm files in Freemind, even though i) Nautilus knows they are now Freemind maps (and not troff or whatever it thinks without Freemind installed) [09:37] It doesn't even list Freemind in the "Open with other application" list so you can't choose it as the default.... [09:39] there is indeed something very odd with the sound quality on the latest coldplay album [09:40] thought the amazon reviewers were just being petty audiogeeks [09:40] but it is blatant [09:43] Good morning everyone. [09:43] o/ [09:44] moring [09:49] i got it [09:49] thanks Laney / daubers [09:50] seems it was permissions [09:50] sorry went to get coffee [09:50] chmod go-w ~/ [09:50] chmod 700 ~/.ssh [09:50] chmod 600 ~/.ssh/authorized_keys [09:50] permissions on what? $HOME? [09:50] that done it [09:50] ah [09:50] ok :) [09:50] usually the problem with keys [09:50] must have been the home dir [09:50] dogmatic69: ssh-copy-id deals with most of that :) [09:50] daubers: ill have to figure that one out [09:51] dogmatic69: Very useful for pushing keys around [09:57] how do you check what terminal is being used? [10:01] which shell interpreter? [10:01] echo $TERM will give you the term type [10:01] xterm :O [10:01] how is that happening? [10:02] for this new user i set up its now using xterm... :/ [10:04] the term type is just a set of environment details I think [10:04] My terminator session on my local machine says xterm [10:04] if i type bash it all goes back to normal [10:07] Ah, you want to know what shell it's running rather than the term type? [10:08] ps -p $$ gives you the running shell [10:09] $SHELL? [10:10] Or that :) [10:11] Laney: That gives: /usr/bin/zsh [10:11] yes? [10:11] $4 == PID. [10:11] $$* [10:12] he wanted to know what shell [10:13] sudo chsh -s /bin/bash is the one [10:22] morning [10:26] matt-with-three-t's [10:26] bacula is killing me today :( [10:27] oimon: Captain Archer? Sam Beckett? [10:27] lol :P [10:28] nope, the backup software [10:50] STUPID RYANAIR AND THEIR STUPID SILVERLIGHT [10:50] ahem [10:50] sorry [10:50] Myrtti: whats wrong [10:50] working fine here in FF and chrome [10:51] I'm just venting out my frustration for having to pay a lot of moneys to be in Finland on 1st of Nov [10:52] :/ [10:55] argh. why are there so many sorts of regex? [10:55] I've always wanted to do that on an expense account... just walk into the airport, slap a credit card onto a booking desk and shout "GET ME ON THE NEXT PLANE TO " [10:55] BigRedS: what's the problem? (most tools understand several kinds of regexp, or can use Perl regexps if you need the mto) [10:55] Anyone know how to get diff's -I switch to ignore lines beginning with a semi-colon? [10:56] I've tried -I';' -I'[;]' -I'^[;]' -I'^;' and I'm sure several others [10:57] BigRedS: don't Diff lines always start with + or - or " " [10:57] nah, I'm trying to get diff to ignore those lines [10:57] I'm incredibly close to piping diff through grep [10:58] BigRedS: maybe the GNU Info page has more detailed docs [10:58] BigRedS: you could try --ignore-matching-lines='^\;' [11:00] yeah, tried that [11:01] BigRedS: is the ; part of diff's output, or is it part of the file? [11:01] it shuold be part of the file I think [11:01] part of the file [11:01] it's a recursive diff into /etc/php5/ on two machines [11:01] BigRedS: http://www.manpagez.com/info/diff/diff_7.php#SEC7 [11:02] BigRedS: sorry for the eye-disease inducing website colours [11:02] but that explains when it "fires" [11:03] ah! [11:03] dammit, user error :( [11:04] diff -I '^;' 1.txt 12.txt [11:04] works for me [11:07] my differences, though are 4-5 lines each beginning with a semi-colon, and then one in a 'variable = value' format [11:07] and, as per the doc MartijnVdS pointed me at, that doesn't get affected by -I because teh 'variable = value' bit doesn't match ^; [11:08] hmm [11:08] I think this calls for another daft perl oneliner [11:11] hah. this is what I'm after [11:11] diff <(find /etc/php5/ -type f -exec grep -v ^\; {} \; | sort) <(find etc/php5/ -type f -exec grep -v ^\; {} \; | sort) --side-by-side [11:46] <()? Nice trick! [11:48] yeah, that's one of my favourite bash things [11:48] I keep meanign to send that to the podcast as their command line love [11:48] what does it do? [11:49] it means you can have more than one stdin stream [11:49] gordonjcp: see "Process Substitution" in man bash [11:49] * popey is too scared to run it [11:49] oh, I see [11:49] diff <(some process) <(some other process) [11:49] will diff the stdouts of those two processes [11:49] MartijnVdS: yeah, I figured it out just as you said that [11:49] gordonjcp: it executes the command between () and provides its output as a /dev/fd/* named pipe [11:49] yes [11:49] it was the question mark you put at the end that threw me [11:49] gordonjcp: and it passes _the /dev/fd/* filename_ to the process [11:50] popey: Command Line Luuurrrve [11:50] the smiley face fork bomb is the most evil of things to trick a noob into...how could smiley faces crash your PC? [12:09] * BigRedS googles [12:10] ah. I'd never seen that as having a smiley face... [12:12] man [12:13] Laney: sup [12:13] sending emails to companies wot have done wrong feels good [12:16] done wrong in the ethical sense of the term, or just common-or-garden bad service? [12:16] I'm in the midst of complaints with four different banks... [12:17] just having a rip off price [12:22] Ah, striping the customer. It's the American way! [12:22] not just American [12:24] and no price on the shelf end so that I could have told so before getting to the till [12:26] :( not a guest === Guest3890 is now known as gord [12:28] ah, gord's been undercover [12:39] hmm what to buy the wife for 6th anniversary? [12:40] oimon: ironing board [12:40] New oven? [12:40] iRon? [12:40] MooDoo: nah, she doesn't use her existing one enough [12:41] oimon: pah training then ;) [12:41] 6th wedding anniversary gifts traditionally have a theme of Iron and Sugar. [12:41] we already have 2 irons :-\ [12:41] oimon: cuppa tea, victorian style [with the home cooked meal thrown in] [12:42] maybe an iron cast of alan sugar [12:42] hahaha [12:42] yes! [12:43] or a sugar cast of jeremy irons [12:43] new set of fireplace pokers [12:43] or chocolate , flowers and a takeaway (more likely) [12:43] she can wave them at ya [12:43] we have a fireplace but nothing to poke [12:43] wow. three minutes to go from suggesting a new iron to suggesting flowers :) [12:44] oimon: bacon press [12:44] i have it easy, she loves flowers [12:44] cast iron weathervane [12:45] http://www.google.co.uk/search?q=iron+bacon+press&hl=en&prmd=imvns&source=univ&tbm=shop [12:45] i want one [12:45] if she doesnt like it, give it to me [12:45] wow [12:45] yes, flat, evenly cooked bacon ftw [12:45] talk about unitasking items [12:45] the unix way [12:46] oimon: it's not an unitasking item [12:46] if you grind small combing on the side, you can use it to spread tiling plaster ;-) [12:46] erm, grout [12:46] love those hostmasks [12:47] deary me http://unclutterer.com/2011/10/12/unitasker-wednesday-pizza-scissorsspatula-cut-n-serve/ [12:49] i would think that my company would be a sufficient present, but no [12:57] how many kg's do you think amy winehouse weighed? 50? [12:57] she had 416mg of alcohol per 100ml of blood when she died. [12:58] oimon: does anyone really care? [12:59] * MooDoo takes his horrible hat off :) [12:59] how many ml is 416mg of alcohol? [13:00] I'd imagine of the order of 400ml [13:00] assuming its density isn't so far from that of water, but I'm not really sure [13:00] quick question for the audio inclined [13:00] a quick back of the envelope calculation shows prob 16 glasses of wine [13:00] tonytiger: for example [13:01] has anyone here ever heard the term "windsock" used to describe a popshield? [13:01] one of our sales guys has been stomping about moaning that he can't find replacements for the foam covers on boom mikes [13:01] and keeps finding information about airfields [13:01] 400ml is bigger than the 100ml that it would have to fit into [13:02] KrimZon_2: i was using http://dogsbody.psych.mun.ca/Tools/BAL/tutorial.html and assuming 50kg female [13:04] gordonjcp: i think the term is windscreen [13:05] if you are talking about mic covers? [13:05] A microphone windscreen is sometimes called a wind gag, or dead cat or yet [wikipedia] [13:05] s/yet/yeti/ [13:16] oimon: I've heard the term wind gag for the dead rabbit, yes [13:16] Yeah, I've never referred to them as windsocks. [13:16] oimon: but I've only ever seen the foam ones referred to as popshields [13:17] tonytiger: as far as I'm concerned a windsock is a thing you get at an airfield, usually in pairs [13:17] they took away one of the windsocks at Broadford because they kept pointing towards each other [13:17] confusing [13:18] what's the mic model? [13:18] oimon: oh, some el-cheapo communications boom mike [13:18] but it's a fairly standard sort of size [13:18] http://www.amazon.com/Rode-Deadcat-Wind-Muff-Microphone/dp/B000BH437S also refers to them as wind muff [13:18] http://en.wikipedia.org/wiki/Microphone#Microphone_windscreens [13:18] we actually have some theatre sound and lighting guys in the industrial unit opposite, but Dougie the sales director is too scared of them to go and ask if they know where to get them [13:19] i do sound engineering but my training is non-theoretical, more on-the-job [13:19] likewise [13:20] don't ask a sound guy for advice unless you're prepared for the answer. IMO they tend to be worse than computer nerds [13:21] check out the list of online shops at http://www.shure.co.uk/meta_en/where_to_buy/dealer_locator [13:27] oimon: gordonjcp's nerdy audio conversation at oggcamp made me feel _really_ good about how I wasn't so nerdy after all [13:27] BigRedS: which day? [13:27] official talk or casual chatter [13:27] nah, pub at the end of it. [13:28] ah..had to return to base after the end of proceedings [13:29] yeah, I wasn't there long - had to get to the south coast for dinner [13:29] BigRedS: thanks, that's the nicest thing anyone has said all day [13:30] BigRedS: I'm strangely proud of how many people actually said that it was by far the geekiest thing they'd heard all weekend ;-) [13:30] hells yeah, I outgeeked a geek conference [13:30] (tbh the GCode 3D printing guys outgeek me) [13:31] gordonjcp: ah yeah, i heard the legends of your talk [13:31] I think I saw the title and decided it'd outgeeked me [13:31] just took a myers-briggs test to check i'm still the same :) http://www.humanmetrics.com/cgi-win/jtypes2.asp [13:31] well, that and your explanation [13:31] complex numbers are fun [13:35] complex numbers annoy [13:35] nah, they're easy [13:35] I still remember the moment at uni when they suddenly made sense to me [13:35] complex vectors especially so [13:35] and the realisation about forty seconds later that it was probably a good time to stop looking into them [13:36] gordonjcp: you must work with AC power [13:36] when you think in terms of a complex vector things like phase and frequency become really clear [13:36] MartijnVdS: RF [13:36] MartijnVdS: got a bike? [13:37] gordonjcp: yes [13:37] MartijnVdS: turn it upside down like you were going to change a tyre, and look at the front wheel [13:37] the valve is the tip of your vector [13:38] with the valve at the top we are at z=0+j1, the real component is zero and the imaginary component is 1 [13:39] gordonjcp: http://blip.tv/dimensions/dimensions_5_english_ipod-1785604 [13:39] as you turn the wheel clockwise the horizontal distance from the tyre valve to the spindle describes a sine wave, and the vertical distance describes a cosine wave [13:39] gordonjcp: best explanation I've seen :) [13:39] I always like complex numbers for making certain types of calculus easier [13:39] and removing the need for stupid trig ids [13:39] * popey divides daubers by zero [13:40] Now there are an infinite number of me's! [13:40] omg [13:40] daubers: yes [13:40] MartijnVdS: the faster you spin the wheel, the higher the frequency. Where the wheel is around its rotation is the phase [13:41] from that you can see that if you spin both wheels at the same speed, they have the same frequency but different phase (maybe) [13:41] gordonjcp: I get to go through all this again soon for my OU degree [13:42] daubers: I'm not a mathematician and I don't even play one on TV [13:43] maths is easy. Making it useful is hard [13:44] daubers: hence my rather rambling talk on SDR [13:44] I was a bit M6-lagged [13:44] Ah! That was you! [13:44] * daubers twigs [13:44] by that point I'd had about six hours sleep in two days ;-) [13:45] four of which were in a very warm tent being slowly intoxicated by paraffin fumes [13:45] I tried looking into SDR at Uni as we were building a small radio telescope. Ended making it hardware defined as we ran out of time [13:45] butane fumes are better for you [13:46] In a still not very good for you manner.... [13:47] daubers: ah, oaky [13:47] *okay [13:47] daubers: with stuff like the funcube dongle now it would be dead easy [13:48] I wanted to adapt a 30m band Softrock to 10.7MHz so I could use it as the IF of an otherwise conventional receiver, for radioastronomy and satellite observation [13:49] Cool, first radio thing I built was a simple long wave reciever to try and listen to the sun :) [13:49] * BigRedS has been outnerded again :) [13:51] gordonjcp: http://www.dimensions-math.org/Dim_CH5_E.htm [13:51] daubers: I listened to Black Hole Sun on my first radio receiver 8-) [13:52] :) [13:53] MartijnVdS: nice [13:55] MartijnVdS: interesting where he talks about multiplications [13:55] in SDR, you shift the frequency of the incoming samples by multiplying them with a rotating vector, which is a mathematical model of a diode ring mixer where two voltages are multiplied [13:56] your rotating vector is of course really just numbers pretending to be two sine oscillators exactly 90 degrees out of phase [14:00] gordonjcp: I've tried to understand QAM and QPSK etc but it gave me headaches. Is this like that? [14:02] MartijnVdS: not really, no [14:02] MartijnVdS: I mean if you want to have a play then you can grab lysdr from github and build it [14:02] if you felt inclined to make a PPA I would have no objections [14:02] jack is a faff in Ubuntu though [14:04] * MartijnVdS doesn't know anything about radios, apparently [14:05] AlanBell: tickle [14:05] * AlanBell giggles [14:08] aww [14:08] AlanBell: like a little girl? [14:18] * oimon wonders why vmware server not working, fiddles with router config, realises someone has stuck wrong hostname label on switch and tricked oimon [14:25] oimon: hurr [14:25] oimon: you've broken mine have you, lost connectiong to my windows server ;) [14:25] no that's just Microsoft [14:25] lol [14:43] gordonjcp: This is also quite readable, but not really about complex numbers (more about how transmitters/receivers work with digital signals :) http://cp.literature.agilent.com/litweb/pdf/5965-7160E.pdf [14:58] hi all o/ [15:02] g'morning! [15:05] o/ [15:06] Good night [15:06] guys do you all know what your personality types are? [15:06] 4pm, yikes! [15:06] (myers briggs) [15:06] Deranged [15:06] interested in what results geeks get [15:06] lo BigRedS :) [15:07] found this quite useful for me: http://www.personalitypage.com/INTJ.html [15:11] * gordonjcp got INTP, no idea what that means in reality [15:12] oimon, that's me. [15:13] iclebyte: try the test http://www.humanmetrics.com/cgi-win/jtypes2.asp [15:13] it's very useful in learning how to relate to people [15:13] and understanding team member [15:13] Is it normal for connections over a VPN to take a _long_ time to establish, or is it just this one client's set up? [15:14] i read one description of INTJ that basically said "quick to jump in and answer questions on irc" [15:14] bigcalm, what kind of vpn? openvpn ? [15:14] iclebyte: F5 [15:14] bigcalm, not used that but openvpn is up in a couple of seconds or there is an issue. [15:15] do you have forward & reverse DNS entries [15:15] bigcalm: pptp vpn from Ubuntu lapdog to Arch desktop at home on cable, crap connection here at work, takes about ten seconds [15:15] I had to hunt down a pyton/C script to be able to make a connection [15:15] To SSH in it takes in excess of 30 seconds for the password prompt to appear [15:15] it could be name resolution realted [15:16] Connecting to an IP address [15:17] bigcalm, is the ssh connection slow once you've logged in after the 30 seconds? [15:17] * awilkins usually comes out INTJ [15:17] iclebyte: no. And I was able to send a file over scp to the remote server at 1.3MB/s [15:18] interestingly the number of people with aspergers with INTJ/P is v high [15:19] bigcalm, then i would say it might be a reverse dns issue. [15:19] Just timed it. 53 seconds [15:19] oimon, It doesn't surprise me, all those questions about social scenarios [15:19] yeah lol [15:20] bigcalm, when logging in the ssh server by default will try and lookup a reverse entry for your client, this can cause problems if its not running. try disabling reverse dns lookups on the SSH server in /etc/ssh/sshd.conf and try again [15:20] i get vertigo type feeling in crowds [15:20] http://paste.ubuntu.com/719754/ that is the part that took the longest [15:20] My personal idea of hell is the Trafford Centre (big mall near Manchester) on a Saturday close to Ch*****as [15:21] iclebyte: sadly I don't have the permission to mess with the SSH server on the remote end. [15:21] Just about tolerable if I'm alone. If I'm with the wifelet, I'll want to kill someone within about 10 minutes. [15:21] i get it subconciously. as i walk through a narrow gap along with other people, i suddenly feel dizzy before i get a chance to process what's happening [15:22] same with walking up steps in a crowd [15:22] the weird thing is, it only happened in the last few years [15:23] INTJ. surprise surprise [15:24] NERD :P [15:25] bigcalm, do you have the ability to ensure that there is a reverse dns entry for the host from which you are connecting? [15:26] iclebyte: not really :) I'll make do with the time delay [15:26] It's interesting to revisit this stuff, I just got promoted to a role with more management responsibility [15:27] Apparently us INTJs like to be the "man behind the curtain" [15:27] totally the techie personality type [15:27] "Forced to conform to inefficient procedures, go through the often wasteful motions of unnecessary meetings or sacrifice authenticity for political correctness, the INTJ, in such an environment, may encounter great frustration." [15:27] i like to make things happen but only if not the centre of attention [15:27]
