[00:21] <diddledan_> linux 4.1: •EXT4 gains file-system level encryption (thanks to Google)
[00:23] <daftykins> D:
[00:24] <zmoylan-pi> so as long as you trust google we're good?
[00:35] <diddledan_> lol
[00:36] <intrbiz> what advantages does that have over the current layered approach
[00:36] <diddledan_> intrbiz: it actually understands files
[00:36] <intrbiz> so
[00:37] <diddledan_> intrbiz: it's like "what advantage does bundling multiple-device support into the fs layer have over the current layered approach"
[00:38] <intrbiz> well the advantage of the layered aproach, is one set of code can encrypt any filesystem, thanks to the layering
[00:39] <intrbiz> and by encrypting the entire block device, limits any potential metadata leaks

[00:51] <daftykins> just a wee download for this new Samsung Note 4
[01:03] <diddledan_> 40 minutes!
[01:03] <daftykins> it's really crawling compared with my tubes capability, yeah
[01:03] <daftykins> totally not been that mind you
[01:04] <diddledan_> that's silly - maybe it's doing it over cellular? :-p
[01:04] <daftykins> the seconds are going - 2 per second
[01:04] <daftykins> nah no SIM
[01:04] <daftykins> granite house :>
[01:04] <daftykins> you won't get above EDGE in here
[01:04] <diddledan_> EDGE is painful
[01:04] <diddledan_> in walesland I had like a 5000ms ping
[01:04] <diddledan_> (yes, 5 seconds)
[01:04] <daftykins> lol
[01:05] <diddledan_> meant doing anything was impossible
[01:05] <daftykins> rage inducing
[01:05] <zmoylan-pi> ♪ if i had the only 2400baud modem in the world... :-) ♫
[01:14] <diddledan_> rough calculations suggest a throughput of 13Kbit/s
[01:14] <diddledan_> basing on the 5ish second latency and a 64Kbit connection speed
[01:15] <diddledan_> (formula gained from: http://bradhedlund.com/2008/12/19/how-to-calculate-tcp-throughput-for-long-distance-links/)
[01:15] <diddledan_> maybe I did that wrong tho
[01:17] <diddledan_> ok, redoing the calculation basing on better numbers (I think) suggests 6Kbit
[01:17] <diddledan_> 6Kbit/s
[01:18] <diddledan_> again, 64Kbit/s connection speed
[01:22] <diddledan_> I still think I've done it wrong
[01:24] <intrbiz> article doesn't window scaling
[01:24] <intrbiz> which will ramp up the window size asumming low packet loss
[01:25] <intrbiz> doesn't mention*
[01:26] <diddledan_> ok, yeah, around 6Kbit/s throughput (without scaling)
[01:27] <diddledan_> or that might be an order of magnitude out
[01:38] <diddledan_> someone check my calculation: 65536 = bits/s connection speed; 1Gbit divided by connspeed = 1*1024*1024/65536 = 16; tcp window size divided by 16 = 524288/16 = 32768; finally 32768 / latency in seconds = 32768/5 = 6553.6bits/s or 6KBit/s or 0.8Kbyte/s
[01:38] <diddledan_> I really can't figure out if my logic is correct tho - it's late and my brian isn't working
[03:16] <diddledan_> there's illumination on the horizon

[08:39] <diddledan__> I'm good ta
[08:49] <brobostigon> morning boys and girls.
[09:18] <bigcalm> Good morning peeps :)
[09:18] <bigcalm> intrbiz: re-pong
[09:18]  * diddledan holds his nose
[09:19] <diddledan> re-pong is worse than pong because you're doing it a second time
[09:19] <diddledan> stinky!

[12:49] <davmor2> MooDoo: I'm good thanks you?  sorry lots of work and pings :)
[12:50] <MooDoo> davmor2: not to worry mate
[14:02] <ujjain> hey, will linux servers crash at the leap second 2015 next week?
[14:04] <bigcalm> Tempting to be deviant....but I can't bring myself to be so
[14:04] <bigcalm> ujjain: no
[14:04] <ujjain> I have a very old kernel and I can't update it though
[14:05] <ujjain> Linux 3.2.0-38-virtual #61-Ubuntu SMP Tue Feb 19 12:37:47 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
[14:11] <directhex> ujjain: no - but individual daemons might
[14:11] <directhex> you'll just see "Clock: inserting leap second 23:59:60 UTC" in dmesg
[14:13] <Azelphur> Can anyone recommend a good board/cpu/case for a home server / transcoding build? currently looking at http://uk.pcpartpicker.com/p/MpNFxr and wondering if anything better is available
[14:36] <davmor2> Azelphur: http://www.serversplus.com/servers/tower_servers/hp_tower_servers/814483-421
[14:38] <davmor2> Azelphur: or http://www.serversplus.com/servers/tower_servers/fujitsu_tower_servers/svfuj-t1311sx070 with £100 cashback
[14:40] <davmor2> Azelphur: also http://www.dabs.com/products/asus-amd-fm-performance-bundle--includes-a88xm-a-fm2---a10-7700k--corsair-8gb-ddr3-vengeance-pro--B8P5.html?src=3 if you want to build yourself
[14:41] <davmor2> Azelphur: but to be honest if it is mostly a server buy a server :)
[16:32] <diddledan> I filed a bug in mozilla! :-o https://bugzilla.mozilla.org/show_bug.cgi?id=1177098
[16:33] <daftykins> :o
[16:43] <diddledan> bbl
[17:27] <Azelphur> Interesting question, I have a 5TB drive with data on it, I have two more 5TB drives that are empty. Can I set up RAID5 without having to move the data off the 5TB somehow?
[17:32] <popey> https://wiki.archlinux.org/index.php/Convert_a_single_drive_system_to_RAID
[17:32] <popey> seems needlessly complicated :)
[17:33] <popey> http://raider.sourceforge.net/ may be better
[18:05] <davmor2> popey: it's archlinux ofcourse it is overly complicated :P
[18:05] <daftykins> hehe
[18:10] <popey> hmmm http://paste.ubuntu.com/11769090/
[18:10] <popey> keeps dropping off the sata bus
[18:10] <popey> my windows boot disk, which is annoying
[18:11] <popey> have a feeling it's just the connector
[18:13] <daftykins> ugh sandforce
[18:14] <popey> yeah, it's one of my older ssds
[18:14] <popey> think it's probably due replacement
[18:14] <daftykins> popey: your means of getting GTA goodness aren't hugely successful are they? :)
[18:14] <popey> haha
[18:15] <daftykins> how'd the Amazon prod go with regard to the iffy drive btw?
[18:15] <popey> i am not convinced the hdd was iffy now
[18:15] <daftykins> did they want it back, or?
[18:15] <daftykins> oh? but it had 14 sectors awaiting remap?
[18:15] <popey> too much like coincidence to have two drives in the machine fail
[18:15] <popey> yeah, this one is more important to fix first
[18:15] <daftykins> did that ddrescue run through fine to clone it?
[18:15] <popey> amazon initially refuse to take it back because it's beyond the 1 month
[18:15] <popey> yes
[18:16] <daftykins> ah good good
[18:16] <popey> so I have another disk in the machine
[18:16] <daftykins> i'd zero fill it to force all the remaps to complete, then have another look at the smartctl output to see what the final tally of remaps is
[18:16] <popey> yeah, once I fix this ssd :)
[18:16] <daftykins> *nod*
[18:16] <popey> its doing a smartctl long test
[18:16] <popey> 48 mins left
[18:17] <daftykins> IME if the cabling is all fine, all wonky SSDs seem to behave after a nice secure erase
[18:19] <daftykins> hrmm i should drop that mates WD Purple serial number into my account to have it reg'd
[18:19] <daftykins> i wonder if you can label them to know which belongs to whom
[18:20] <popey> well, it's interesting here to note that in a USB caddy this disk hasn't failed at all
[18:20] <popey> yet it fails off pretty much immediately after boot in desktop
[18:20] <daftykins> hrmm
[18:20] <daftykins> so could be as simple as a cable as you say?
[18:21] <popey> yeah, hopeful
[18:21]  * popey goes to make food and stop watching this disk light flash :)
[18:22] <daftykins> :D
[18:22] <daftykins> oh yeah it's getting that sorta time
[18:22] <davmor2> popey: you are going to watch it over ssh on your phone aren't you
[18:23] <daftykins> XD
[18:26] <davmor2> popey: you byobu has a raid item right ;)
[18:40] <popey> bah
[18:40] <popey> its now dropped
[18:41] <popey> http://paste.ubuntu.com/11769256/
[18:41] <popey> thats bad
[18:42] <daftykins> wowzer
[18:43] <daftykins> heh SSD in RPM shocker
[18:45] <popey> yeah, maybe I shouldn't have it on a high speed turntable
[18:45] <daftykins> :D
[18:45] <daftykins> that'd fit so well if Windows was boot looping
[18:46] <popey> i have a plan
[18:47] <popey> one day
[19:02] <popey> Right, so we're gonna dd zeros on this original 4TB, right daftykins ?
[19:06]  * popey kicks off a smartctl -t long on it
[19:06] <daftykins> popey: yep
[19:06] <popey> guess I could dd zeros while smart does its thang
[19:07] <daftykins> on the same, or on the SSD?
[19:07] <popey> ssd is toast
[19:07] <popey> this is the 4TB
[19:07] <daftykins> ah ok
[20:22]  * popey puts ssd in server and tries to get something off it with ddrescue
[20:22] <popey> worth a punt, if it works I can dd it back to another disk and I'm back up and running
[20:23] <daftykins> ^_^
[20:24] <popey> found another ssd on my desk which I could use, but it's 5G smaller, so will need to mount the image and shrink the partition inside it
[20:24] <popey> or I could use something else, ah I dunno.
[20:25] <daftykins> mmm i've had to perform too much trickery with clonezilla to get around a size mismatch like that
[20:25] <popey> once I get it into an image I can happily play around with it
[20:25] <popey> might just be easier to put it on a bigger disk tho
[20:26] <popey> assuming I get the data off this!
[20:26] <daftykins> doin' the ol' chess manouevre of thinking many steps ahead :>
[20:26] <popey> ha
[20:27] <popey> yes, i have a plan! Got a spare 2TB disk I think I'll use instead.
[20:27] <popey> ddrescue: input file disappeared: No such file or directory
[20:27] <popey> haha
[20:27] <popey> that fails then
[20:27]  * popey will keep trying
[20:27] <daftykins> surely not much to it beside a stock Windows install?
[20:28] <popey> yeah, it's just the time hassle
[20:28] <popey> I'd just rather not
[20:29] <daftykins> hmm, could be equal!
[20:29] <daftykins> would be nice if Microsoft respun media regularly, to stop the Windows Update wait
[20:29] <popey> yeah, there's tons on there I dont want to reinstall
[20:31] <daftykins> ah i was assuming it was there for the games alone
[20:32] <MartijnVdS> daftykins: the windows 10 isos are refreshed every time a new build comes out :)
[20:32] <MartijnVdS> but that's betas
[20:32] <popey> yeah, its mostly games but there's a few other things on it
[20:33] <popey> and it has accounts for the kids with their nonsense
[20:33] <daftykins> MartijnVdS: yeah so completely moot reply, but given the new rolling release approach who knows? maybe they'll do periodic ones
[23:00] <diddledan_> yawn
