bdukMorning peeps04:45
theblazehenThatGraemeGuy: "sudo apt-get purge minetest*" That won't try and expand in the shell?05:13
ThatGraemeGuymorning06:06
ThatGraemeGuytheblazehen: actually no, and interestingly enough i've never even realised before that its weird06:06
Kiloshi ThatGraemeGuy and others06:06
ThatGraemeGuyalthough if you happen to have any files in your current dir that match the glob,but the files don't match any package names, then you get an error06:07
ThatGraemeGuyhttp://slexy.org/view/s2j99f5O8D <-- like that06:08
ThatGraemeGuyof course, the correct answer is to always quote arguments where you don't want bash globbing them06:12
ThatGraemeGuysudo apt-get purge 'minetest*'06:13
ThatGraemeGuyso Kilos have you decorated your whole house with paintings and installed a bunch of appliances already? :-)06:14
ThatGraemeGuyand built a mesecons door that opens when you walk near it06:14
Kiloshaha no man i have to find flowers or something to mmake coloured stuff06:14
ThatGraemeGuyyeah06:15
Kilosthere is just too much to work through06:15
ThatGraemeGuyi've been stocking up on flowers for ages06:15
Kilosah06:15
ThatGraemeGuyyou'll see i have a bunch around my house06:15
Kilosyeah06:15
Kilosi only planted a few06:15
ThatGraemeGuyevery now and then i pick all but 1 of each colour then after a while they spread again06:15
Kilosoh they spread automatically?06:16
ThatGraemeGuyyes06:16
Kiloscool06:16
ThatGraemeGuyhttp://wiki.minetest.net/Flower06:16
ThatGraemeGuyhttp://wiki.minetest.net/Group:flora06:16
ThatGraemeGuyso basically plant them on grass, make sure there's enough space around them and they will spread slowly06:17
Kilosdidnt worry much about flowers because i dont plant much that doesnt bear fruit06:18
Kilosin real life that is06:18
Kilosapart from herbs of course06:18
ThatGraemeGuyi still want to try placing a lot of dirt in an underground cavern and then have a lot of super glow glass above it, i'm pretty sure it'll grow grass06:18
Kilosoh you havent seen06:18
ThatGraemeGuyseen what?06:19
Kilosbart got tired of the long trip up for wood so he complained and i had to go make him an area with his own wood down there06:19
Kiloslemme find screenshot06:19
ThatGraemeGuyhaha06:20
ThatGraemeGuywood is easy though it grows in the dark06:20
ThatGraemeGuygrass and flowers need light06:20
ThatGraemeGuyyou must make a chest at your house with a teleporting tube and another down the mineshaft, then you can teleport stuff down there06:22
Kiloshttp://picpaste.com/screenshot_284335666-v81hc0qG.png06:22
ThatGraemeGuylol nice06:22
Kilosi put lotsa lights but thats also where all that mese was06:22
ThatGraemeGuytrees don't need light, just so you know for future06:22
Kilos3 more piles apart from that last shot of the blocks and mese06:23
Kilosty06:23
Kiloswithout light ill keep walking into them hehe06:23
ThatGraemeGuyoh, something else i noticed from the changelog06:24
ThatGraemeGuy- Punch bones to pickup items, drop them if no space for bones06:24
ThatGraemeGuyso it seems you can just click your bones to pick up all the items contained in them06:25
ThatGraemeGuyi haven't tested though06:25
ThatGraemeGuyeasier than transferring one stack at a time06:25
Kilosyeah that was big work06:25
ThatGraemeGuythey also added desert cobblestone but i think that only affects newly-generated worlds06:25
Kilosi just get a blue screen with clouds06:26
Kilosneed to restrt it i think06:27
Kilosit keeps telling me i should upgrade my client06:29
ThatGraemeGuyno it doesn't, read it properly06:29
Kilosplease note that the server has been updated, you should probably update your client too06:31
ThatGraemeGuyyeah, ok maybe i should add "if you have not already done so", happy? :-p06:33
ThatGraemeGuyi thought i was being helpful06:33
Kiloshahaha oh that was you06:33
Kilosspinza, ping06:48

charli name each tab according to the irc network it's running in09:17
Symmetriacan someone do me a favour and ftp to ubuntu-releases.mirror.liquidtelecom.com09:58
Symmetriaand attempt to pull one of the ISO's09:59
Symmetriaand just let me know if its working properly09:59
charlSymmetria: on it10:01
charlSymmetria: working fine it's just *really* slow10:02
charlSymmetria: i'm getting less than 1MBps10:02
charlah now it's slowly starting to climb, hitting 1,5MBps now10:03
ThatGraemeGuygetting in the region of 3MB/sec10:05
charlhmm lemme do a mtr10:05
ThatGraemeGuyaround 6-7MB/sec now10:05
Kiloswow thats fast ThatGraemeGuy 10:05
charlonly about 8 hops, shouldn't be that bad, latency around 170ms10:05
charlThatGraemeGuy: you are talking about megaByte right, not megabit?10:06
ThatGraemeGuyyes10:06
charlyeah that's more than fair10:06
Symmetriathats nifty, on what link are you on and where are you based10:06
SymmetriaI did a test to UFS in bloemfontein and was getting 40MBytes/second as well10:06
ThatGraemeGuyI work at Hetzner :)10:07
Symmetriacan you do a tracroute and paste it to me?10:07
SymmetriaIm just verifying everything10:07

Symmetriathats decent 10:08
Symmetriacan you gimme a trace to the server?10:08
ThatGraemeGuyhttp://slexy.org/raw/s2WXY9qqYE10:09
Symmetriacharl, heh, I can give you some settings to apply to your box to re-test if you want that shold make it a shitload faster :P10:09
charlSymmetria: yes please10:10
Symmetriahow much ram is in your box?10:10
charlSymmetria: 4 GB10:10
Symmetriaok, gonna give you some settings, I would suggest you revert back to the old settings after the test though10:11
Symmetriacause you don't have the ram to run these settings long term10:11
Symmetrianet.core.rmem_max = 6710886410:11
Symmetrianet.ipv4.tcp_rmem = 4096        131072   3355443210:11
Symmetrianet.core.wmem_max = 6710886410:11
Symmetrianet.ipv4.tcp_wmem = 4096        131072   3355443210:11
Symmetriaset that and then try the download again10:11
Symmetria;p10:11
charlhmmm ok10:11
Symmetriasysctl -a |grep on those and save the old values 10:11
Symmetriaso you can revert back afterwards10:11
Symmetria;p10:11
Symmetrialet me know what those settings do to the transfer speed10:16
charlinteresting, right at the start it shot up to about 7MBps and then dropped down to what it was (1,5MBps)10:22
charlrestarted the wget, a couple of times, now it stays slow - irratically moves between 1,5MBps and 700KBps10:24
charlok deleted the file and am starting over, so that i can get a good average speed indication10:25

charltheblazehen: what you doing?17:14
theblazehencharl: own mesh network thing17:21
theblazehenTrying to encrypt multiple kilobytes with public key crypto17:21
theblazehenI probably shouldn't be implementing crypto...17:23
charltheblazehen: don't you just use an existing crypto library ?18:06
charli've done it lots of times it's really simple18:06
charldo all your rsa/dsa, aes etc, blowfish whatever you want18:06
theblazehencharl: I'm using pycrypto18:17
theblazehenBut need to encrypt largish amount of data with public key crypto18:17
theblazehenSo I'm now splitting it in 128 byte chunks, encrypting them and joining them18:18
theblazehennight all18:27
ThatGraemeGuy'lo peeps18:30
