brobostigon | good morning everyone. | 10:27 |
MartijnVdS | \o | 10:35 |
brobostigon | morning MartijnVdS | 10:35 |
* brobostigon had a spectacular idea in a halfasleep state this morning, he envisaged his own shop on second-lif | 10:47 | |
MartijnVdS | is second life still going then? | 10:47 |
brobostigon | yes. | 10:48 |
Rory | Hey, does anyone read Linux Format in here? They did a roundup either last issue or the one before, of RSS readers, and I can't remember the winner (it wasn't Feedly) | 11:29 |

bigcalm | Hi peeps :) | 13:06 |
Neoti | Anybody in here from around nottinghamshire and who has a CB Radio ? | 13:20 |
gordonjcp | Neoti: that seems an oddly specific request | 13:25 |
* gordonjcp does not have a CB radio but does have a lot of radio equipment | 13:25 | |
Neoti | gordonjcp: i just want to do a radio check thats all ... | 13:25 |
gordonjcp | Neoti: no-one on Ch. 19? | 13:26 |
Neoti | AM or FM, low mid or hi ? lol... | 13:26 |
gordonjcp | well both 27/81 and CEPT require FM | 13:26 |
Neoti | well i have a superstart 120 fm. i am on channel 19 hi | 13:27 |
gordonjcp | ooo | 13:27 |
gordonjcp | if conditions are up you might hit one of the websdr sites | 13:28 |
Neoti | nope no one out there... | 13:29 |
gordonjcp | if you can hear skip from Holland you might be able to hit the WebSDR at Twente | 13:29 |
gordonjcp | 7MHz aside, I'm not that into all this close-to-audio stuff | 13:30 |
* MartijnVdS just ordered one of those Realtek-chipset DVB sticks | 13:48 | |
MartijnVdS | to play with rtl-sdr | 13:48 |
penguin42 | yeh they're kind of fun | 13:48 |
gordonjcp | yeah | 13:49 |
MartijnVdS | the Twente one is also great -- you can see so many cool stuff on the lower bands | 13:49 |
MartijnVdS | much* | 13:49 |
gordonjcp | and what's amazing is not only can you use them as a powerful low-VHF-to-low-microwave SDR, you can use them to watch telly too | 13:49 |
MartijnVdS | DCF-77, some number channels (morse mostly) | 13:49 |
MartijnVdS | gordonjcp: and listen to DAB radio, apparently | 13:50 |
gordonjcp | MartijnVdS: I'm going to toss some photons around later if you want to have a listen | 13:50 |
MartijnVdS | gordonjcp: Well, the rtl-sdr is still in China atm, I really *just* ordered it a few hours ago | 13:50 |
MartijnVdS | but I might give websdr a go | 13:50 |
penguin42 | note that the DVB-t telly stuff is a separate path; it's not done by the SDR data over the USB, the capture bandwidth isn't high enough for that - they have a demod for that | 13:55 |
MartijnVdS | penguin42: yeah, they can only get 3MHz wide from the SDR, and DVB channels are 8MHz wide | 13:56 |
gordonjcp | aha | 13:59 |
gordonjcp | yes | 13:59 |
gordonjcp | the SDR stuff is done using what is effectively a test mode | 13:59 |
MartijnVdS | lots of radio stations on the utwente websdr sound like the TARDIS or the alien probe from Empire Strikes Back | 14:13 |
MartijnVdS | whoa.. bolivian radio stations | 14:16 |
MartijnVdS | .. and a radio station that sounds like the Black Mesa Research Facility | 14:22 |
=== joshmyers is now known as bubu | ||
gordonjcp | MartijnVdS: there are a lot of funny digital modes | 14:53 |
gordonjcp | MartijnVdS: interestingly if you zoom in on some OFDM modes you can see they're more-or-less flat in frequency response | 14:54 |
gordonjcp | and then you see diagonal dark bands moving, which is because of phasing from multipath reception | 14:54 |
MartijnVdS | I have a Wi-Spy, and I see that on the wifi bands I think | 14:55 |
MartijnVdS | diagonal bands | 14:55 |
MartijnVdS | I think that might be some kind of part of the 802.11 protocols though | 14:55 |
MartijnVdS | I know way too little about this.. where/how do I start learning more? :) | 14:57 |
SuperEngineer | Impressed - with only 2GB mmeory & a low end graphics card - just played Half Life on Steam with 8 other programs still open. Didn't even notice. | 15:43 |
penguin42 | SuperEngineer: Looking, Half Life was originally released in '98 so that was probably high end then | 16:04 |
SuperEngineer | ;) | 16:08 |
Azelphur | Anyone know where I might get a copy of a newspaper printed in 2012? | 16:26 |
penguin42 | the newspaper publishers? A library? | 16:27 |
SuperEngineer | Azelphur: local library? | 16:27 |
Azelphur | was hoping for something online if possible | 16:27 |
SuperEngineer | penguin42: snap! | 16:27 |
SuperEngineer | Azelphur: that might cost you a subscrion to particular paper - if they allow archive access | 16:29 |
Azelphur | SuperEngineer: yea, the only archive I've found for this paper is dated 1912 and before | 16:29 |
Azelphur | it's the Kentish Express Ashford edition that I'm after | 16:29 |
SuperEngineer | Azelphur: write to them / send them a usb stick & beg? | 16:31 |
Azelphur | yea guess so | 16:32 |
penguin42 | oh one of the more major papers then.... | 16:32 |
ali1234 | go to library and photocopy it | 16:37 |
Azelphur | yea, seems like a library job for tomorrow :) | 16:56 |
penguin42 | hth do you tell firefox to stop looping gifs ? | 16:56 |

mungbean | bitcoins are $800 now? | 17:15 |
mungbean | thought they were $200 last week | 17:16 |
mungbean | crazy bubble time | 17:16 |
Azelphur | mungbean: :) | 17:16 |
Azelphur | mungbean: this is /after/ the bubble. This is the new stable price now I reckon. | 17:16 |
Azelphur | it was $1000+ in the bubble | 17:16 |
mungbean | bubbles first don't they? | 17:16 |
mungbean | burst | 17:16 |
Azelphur | it did burst | 17:16 |
Azelphur | it dropped to $400 then normalised at $800 | 17:16 |
mungbean | yeah, bursting = $20 again | 17:16 |
mungbean | in my book | 17:17 |
Azelphur | you ain't gonna see $20 again. | 17:17 |
Azelphur | no way :) | 17:17 |
mungbean | thats how bubbles happen | 17:17 |
mungbean | thats what they say just before a stock market crash | 17:17 |
Azelphur | mungbean: Bitcoin is a successful venture, I see no burst nor any reason that it would burst. | 17:17 |
mungbean | ^bitcoin^stock market | 17:17 |
mungbean | something causes collapse in confidence | 17:18 |
Azelphur | xD | 17:18 |
Azelphur | mungbean: that already happened in the past, Bitcoin went to <$1 | 17:18 |
Azelphur | and then it picked back up again | 17:18 |
mungbean | since bc isn't underwriten by anything like gold, it can crash to $0 | 17:18 |
mungbean | price starts dropping, people panic, thenm its a crace to the bottom | 17:19 |
penguin42 | mungbean: But the reasons for buying/selling gold have very little to do with actual using or posessing it | 17:19 |
penguin42 | mungbean: There's a lot of unease about the actual stocks of these precious metals | 17:19 |
Azelphur | mungbean: been there done that, it came back up again. | 17:20 |
mungbean | ok lets talk pork bellies instead | 17:20 |
mungbean | mmm bacon | 17:20 |
penguin42 | mungbean: OK, lets talk guar gum - what influences the price of guar gum? | 17:20 |
mungbean | supply and demand | 17:22 |
mungbean | demand outstrips supply then price ++ | 17:22 |
mungbean | the inherent usefulness of the product | 17:22 |
Azelphur | mungbean: I have my money where my mouth is with bitcoin, so we'll see ;) | 17:22 |
penguin42 | mungbean: Right, so you get something really random happen - like it starts being used by frackers (really) and it shoots through the roof, no one predicted it and then who knows it might stop being used | 17:23 |
penguin42 | mungbean: That's more real - it's actual stocks of the stuff but in principal could be very unpredictable | 17:24 |
mungbean | but is underwritten by more stable markets though too right? | 17:24 |
penguin42 | mungbean: That I don't know, but I think so | 17:25 |
mungbean | ice cream | 17:26 |
mungbean | bc are pure speculation, likethe doctom bubble | 17:27 |
mungbean | not to say you can't make money on the rising tide | 17:27 |
mungbean | i always think of tulip mania at this point | 17:27 |
penguin42 | mungbean: But I think the metal markets aren't necessarily much better than tulip mania, especially for gold which doesn't have an intrinsic use | 17:31 |
SuperEngineer | penguin42: don't let the ISS hear that - they might disagree somewhat | 17:34 |
penguin42 | ISS? (Not space station....) | 17:34 |
SuperEngineer | yup | 17:34 |
penguin42 | does it use much gold? | 17:35 |
SuperEngineer | ...any satellite or spoaceman also thinks it has a rather intrisic use - as so many earthbound bits of kit | 17:35 |
SuperEngineer | penguin42: they use loads of the stuff | 17:36 |
penguin42 | why? | 17:36 |
SuperEngineer | [so does a mobilee phone btw - but to a *much* lesser extent] | 17:37 |
SuperEngineer | spacemen / space instruments they use it for protection - phones use it for vconnections | 17:37 |
SuperEngineer | I use it to make me pretty ;) | 17:38 |
dvrr | how to connect openvpn windows client with certificates please help me | 17:39 |
dvrr | popey | 17:40 |
* mungbean has a gold tooth | 17:44 | |
penguin42 | dvrr: my experience with vpns (which is very out of date and I can't remember much) is that you're probably best finding a relaxent before you start | 17:44 |
mungbean | its a very non reactive metal | 17:44 |
SuperEngineer | mungbean - the only thing that reacts with gold are stooopid "we buy old gold & nick your money" sites | 17:51 |
MartijnVdS | SuperMatt: also, aqua regia | 18:57 |
MartijnVdS | (don't drink that) | 18:57 |
MartijnVdS | uh | 18:57 |
MartijnVdS | SuperEngineer, but he left I guess | 18:58 |
bigcalm | To re-ask a question I posted to twitter: Where do you keep your private GPG keys in case your SSD dies? | 20:41 |
penguin42 | on a separate encrypted device? | 20:42 |
MartijnVdS | hmm QR code 8-) | 20:42 |
daftykins | on a piece of paper! | 20:44 |
daftykins | apparently most SSDs die in read only states though | 20:44 |
daftykins | but yeah wouldn't rely on that :D | 20:44 |
bigcalm | I'd love to get the data off of my dead SSD. But I have managed to install 13.10 onto a smaller, spare, SSD so that I can continue working | 20:45 |
MartijnVdS | daftykins: SSDs have weird half-erased fail states that happen when a block becomes unwriteable | 20:45 |
daftykins | my intel X25-M G2 actually would BSOD win7 when it tried to read/write a bad sector that developed - i had to secure erase the drive to overcome it | 20:46 |
penguin42 | daftykins: But bigcalm's is the 2nd case I've heard of where the drive just died | 20:49 |
bigcalm | The drive longer appears as a drive to any device it is connected to :( | 20:49 |
bigcalm | +no | 20:51 |
daftykins | ouch | 20:51 |
daftykins | controller fail | 20:51 |

bigcalm | AlanBell: yay | 20:52 |
penguin42 | AlanBell: How did you come across that book of pictures of delapitaed places? | 20:52 |
bigcalm | They are exceedingly cheep cables now: http://www.amazon.co.uk/Premium-HDMI-Cable-Gold-Metre/dp/B000GDI6FC | 20:53 |
daftykins | bigcalm: what type is said dead SSD? | 20:54 |
MartijnVdS | bigcalm: yeah, but shipping to not-UK is £expensive | 20:54 |
penguin42 | MartijnVdS: Does your country not have a similar emporium of cheapo electronic bits? | 20:54 |
MartijnVdS | bigcalm: so I'm better of getting some AmazonBasics cables with some other items (to get to free shipping) | 20:54 |
MartijnVdS | penguin42: we have "allekabels.nl", which is cheap but not *that* cheap | 20:55 |
AlanBell | penguin42: #surrey channel on irc.lug.org.uk | 20:55 |
MartijnVdS | also, AmazonBasics cables are £3,99 | 20:55 |
MartijnVdS | not bad imho | 20:55 |
penguin42 | AlanBell: Ah right, I did have someone of the same name who used to work for me for a few years and I seem to remember he was a good photographer as well | 20:55 |
bigcalm | daftykins: OCZ vertex 120GB. I've had 3 OCZ drives and this is the newest one. So I don't hate the brand yet :) | 20:56 |
daftykins | ah-har | 20:56 |
daftykins | original generation Vertex? think there were at least 4+ | 20:57 |
bigcalm | s/I've had/I have | 20:57 |
bigcalm | Ug, bought in Jan last year | 20:57 |
bigcalm | OCZ Agility 3 SATA III Solid State Drive 120GB | 20:58 |
MartijnVdS | penguin42: Amazon sells cables by weight, apparently: http://i.imgur.com/MHT1RfB.png | 20:59 |
penguin42 | nice | 21:04 |
daftykins | MartijnVdS: give me a kilo of your finest HDMIs please, grocer | 21:07 |
MartijnVdS | daftykins: --> Amazon | 21:08 |
daftykins | ;) | 21:08 |
maya- | :D | 21:14 |
maya- | Hi nice peoples! I have a question. I have an HFS+ HDD in Ubuntu, and I’d like to change the permissions to I can read and write to it. I already removed journaling. Any tips? :D | 21:14 |
MartijnVdS | No idea.. I've found NTFS to be the best "shared" FS between Linux en MacOS | 21:15 |
maya- | I’m not looking to share, per se. | 21:15 |
maya- | I just need write access. :D | 21:16 |
daftykins | probably best to avoid HFS+ then | 21:17 |
daftykins | from what i heard the other day it's quite flaky | 21:18 |
Fujio | hi | 21:20 |
daftykins | hello | 21:20 |
popey | hmm, want to root my nexus 7 | 21:33 |
daftykins | why-for? | 21:33 |
popey | to use something that requires it | 21:34 |
daftykins | ah-har | 21:34 |
popey | doesnt seem straightforward | 21:34 |
daftykins | they don't have easily unlockable bootloaders on those things? | 21:34 |
ali1234 | unlocking the bootloader isn't the same as rooting | 21:35 |
daftykins | i know, but often it can be a helpful first step | 21:35 |
ali1234 | it is part of the process though | 21:35 |
Fujio | hi popey | 21:36 |
Fujio | can you run ubuntu on a nexus7? | 21:36 |
popey | Fujio: https://wiki.ubuntu.com/Touch/Install | 21:37 |
Fujio | thanks | 21:37 |
popey | found windows tools to root it, but having difficulty finding a nice easy linux way | 21:39 |
ali1234 | rooting typically means unlocking the bootloader and flashing a custom kernel | 21:45 |
ali1234 | i assume you've already done the former | 21:45 |
Azelphur | ali1234: it does? | 21:45 |
ali1234 | for the latter, just find what kernel image that tool uses and flash it however you'd normally flash | 21:45 |
ali1234 | Azelphur: on nexus stuff it does | 21:45 |
Azelphur | the vast majority of the time people just flash the SU binaries and superuser apk and stick with the stock firmware / kernels o.O | 21:45 |
Azelphur | even more so on the nexus | 21:45 |
ali1234 | how do you "flash" the SU binary if you don't already have root? | 21:49 |
popey | yeah, saw some instructions which is to install an su binary via a modded recovery | 21:49 |
popey | ali1234: custom recovery | 21:49 |
ali1234 | right, modded recovery - which is a kernel image + initrd | 21:49 |
ali1234 | so you flash that the same way you'd flash an ubuntu touch image, for example | 21:50 |
ali1234 | then once you've got a modded recovery you can do whatever you want :) | 21:50 |
spiritech | hi. i am running this command "sudo echo "/dev/sdb1 /media/sdb1 ext4" >> /etc/fstab" i use it as part of an install script. however it says permission denied. how can i run this command as the correct user? | 22:38 |
directhex | spiritech, do you want to know why it doesn't work as-is, or just the answer? | 22:39 |
spiritech | an answer would be ok. though i dont mind both if you have the time. | 22:40 |
spiritech | i always thought sudo gave root perms. | 22:40 |
directhex | pipe to tee. "echo foo | sudo tee /some/file" | 22:40 |
directhex | sudo does. but you're sudoing the "echo" command. the redirect, i.e. the >>, is being done by the parent bash shell, which is not sudo'd | 22:41 |
spiritech | so echo "kagfkasf" | sudo tee /etc/fstab | 22:42 |
directhex | well, "kagfkasf" isn't a valid fstab entry. but yes. | 22:42 |
spiritech | wes. | 22:42 |
spiritech | i mean yessss | 22:43 |
spiritech | i have necer used tee before. | 22:43 |
spiritech | i assume tee reads STDOUT | 22:43 |
spiritech | and writes to destination | 22:44 |
directhex | that's exactly what it does | 22:44 |
directhex | tee - read from standard input and write to standard output and files | 22:44 |
spiritech | so if there is a break in standard input do i need "" or does it do that automatically? | 22:45 |
directhex | test it out into a safe file in /tmp | 22:46 |
spiritech | ok. i will have a play. ty for your help. | 22:48 |
spiritech | also i had probs with usb installer for 13.10 amd 64 desktop iso. i could make the start up usb. when i booted it would not install. had to use the mini.iso in the end. | 22:49 |
spiritech | all good now tho. | 22:50 |
=== Guest77697 is now known as everydaylinuxuse | ||
ali1234 | spiritech: you should be careful about mounting things manually in /media | 23:08 |
ali1234 | the standard is now to mount things under /media/<username>/ | 23:08 |
spiritech | ali1234. i am the only user. and it keeps my scripts more compact. can it cause any serious problems? | 23:26 |
ali1234 | probably not, unless your username is sdb1 | 23:26 |
spiritech | well thats ok then | 23:27 |
spiritech | not sure why media needs a username. surely if its going to be mounted. well, it will be mounted and accessible by the current user. | 23:28 |
ali1234 | for multiuser systems | 23:28 |
spiritech | oh. so certain drives are accessible by cerain users. | 23:30 |
spiritech | surely that could be done with group permissions./ | 23:30 |
spiritech | or maybe not. | 23:31 |
ali1234 | well, you presumably don't want other users to see you've mounted /media/goatpron | 23:32 |
spiritech | yes. whatever goatpron is. | 23:33 |
spiritech | lol | 23:33 |
ali1234 | though i suppose they can still see it on the mountlist | 23:33 |
ali1234 | i don't really know what the real reasoning is | 23:33 |
penguin42 | ali1234: If it was a FAT partition it wouldn't have any permissions and probably anyone can read it? | 23:33 |
ali1234 | you can mount it with umask to fix that one | 23:33 |
ali1234 | though just making private user mount dirs is probably the easiest way | 23:34 |
penguin42 | true, I guess it means you don't get name clashes between different users | 23:34 |
spiritech | so if i log in as a different user. say blobtech. and went to /media/... i would not be able to see the other user list/folders. is that right. | 23:35 |
spiritech | ? | 23:35 |
penguin42 | spiritech: I think that's the idea, and you could both plug in a thumb drive labelled as 'pictures' | 23:35 |
spiritech | or would they be visible and not be able to enter them? | 23:36 |
penguin42 | not sure | 23:36 |
ali1234 | drwxr-x---+ 2 root root 4096 Nov 20 17:51 /media/al | 23:36 |
penguin42 | ooh with acls for extra fun | 23:37 |
ali1234 | that's the +? | 23:37 |
penguin42 | it's got some extra attributes on | 23:37 |
penguin42 | ok that's curious, my trusty box doesn't have /run/media or /media/dg | 23:38 |
spiritech | surely the best way to do this would be to mount all drives in media, then set user permissions for each drive. rather than setting up a mount list to mount drives to certain users? | 23:40 |
penguin42 | spiritech: what happens if both of you wanted to mount say the same remote fileserver or something like that - it actually gets quite tricky depending on the filesystem involved to maintaint aht type of permissions | 23:41 |
spiritech | are we talking about two users, using at the same time. ;) | 23:43 |
penguin42 | yes | 23:43 |
penguin42 | or lock screen and then switch users | 23:43 |
spiritech | oh. i see. i was assuming two users at separate times. | 23:43 |
spiritech | so what your saying is its easier to have user mount points rather than setting user perms for each drive etc. | 23:45 |
penguin42 | nod | 23:46 |
spiritech | so all your stuff is inhere yours/....... and all my stuff is in here mine/.......... | 23:46 |
penguin42 | nod | 23:48 |
spiritech | and its etc/fstab's duty to control where these things get mounted/ or drives anyway? | 23:48 |
penguin42 | no, it's udisks2 these days that does it | 23:48 |
penguin42 | udisks hand;es things like mounting a usb drive you just plug in | 23:49 |
spiritech | it could be done with fstab? | 23:49 |
penguin42 | fstab can't deal with anything dynamic | 23:49 |
spiritech | static stuff tho? | 23:50 |
spiritech | liek int hdd | 23:50 |
penguin42 | oh yeh you can still mount stuff using fstab where ever you like | 23:50 |
spiritech | also i have noticed that if i plug in my 16gb corsair usb stick it is assigned sdc1. if i remove it then plug in my corsair 8gb usb stick it is assigned the same device name sdc1. is this normal? | 23:51 |
spiritech | so both get assigned /dev/sdc1 when plugged in separately. | 23:51 |
spiritech | this is annoying if i want to rsync stuuf on a device level. | 23:52 |
penguin42 | spiritech: You can never trust the order of /dev/sd* | 23:52 |
penguin42 | spiritech: things like /dev/disk/by-label and /dev/disk/by-id etc are much safer these days | 23:53 |
spiritech | ok. well i use device name at the moment. | 23:53 |
penguin42 | spiritech: OK, don't blame us when you over write the wrong one! | 23:54 |
spiritech | no. i mean the format name. | 23:55 |
penguin42 | what do you mean by format name? | 23:55 |
spiritech | like /media/username/corsair8gb | 23:55 |
penguin42 | ah right yes, much safer | 23:56 |
spiritech | the name you give the device when you format it. | 23:56 |
spiritech | i just always wondered if you could do it the /dev/sdc1 way. tho obviously not. | 23:56 |
spiritech | i assume the system just gives out the next available reference when a new device is plugged in. | 23:57 |
ali1234 | it does | 23:58 |
spiritech | so sda sdb sdc so on so forth. | 23:58 |
ali1234 | but /dev/disk/by-id should be a uuid and therefore always unique | 23:58 |
spiritech | how do i find the by-id of a device. | 23:58 |
spiritech | ? | 23:58 |
ali1234 | fdisk -l | 23:59 |
ali1234 | wait, that doesn't work | 23:59 |
ali1234 | you should find they are symlinks anyway | 23:59 |
ali1234 | ls -l /dev/disk/by-uuid/ | 23:59 |
