| zmoylan-pi | so as long as you trust google we're good? | 00:24 |
| diddledan_ | lol | 00:35 |
| intrbiz | what advantages does that have over the current layered approach | 00:36 |
| diddledan_ | intrbiz: it actually understands files | 00:36 |
| intrbiz | so | 00:36 |
| diddledan_ | intrbiz: it's like "what advantage does bundling multiple-device support into the fs layer have over the current layered approach" | 00:37 |
| intrbiz | well the advantage of the layered aproach, is one set of code can encrypt any filesystem, thanks to the layering | 00:38 |
| intrbiz | and by encrypting the entire block device, limits any potential metadata leaks | 00:39 |

| daftykins | just a wee download for this new Samsung Note 4 | 00:51 |
| 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 | 01:03 |
| 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 | 01:04 |
| 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... :-) ♫ | 01:05 |
| diddledan_ | rough calculations suggest a throughput of 13Kbit/s | 01:14 |
| diddledan_ | basing on the 5ish second latency and a 64Kbit connection speed | 01:14 |
| 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 | 01:15 |
| diddledan_ | ok, redoing the calculation basing on better numbers (I think) suggests 6Kbit | 01:17 |
| diddledan_ | 6Kbit/s | 01:17 |
| diddledan_ | again, 64Kbit/s connection speed | 01:18 |
| diddledan_ | I still think I've done it wrong | 01:22 |
| intrbiz | article doesn't window scaling | 01:24 |
| intrbiz | which will ramp up the window size asumming low packet loss | 01:24 |
| intrbiz | doesn't mention* | 01:25 |
| diddledan_ | ok, yeah, around 6Kbit/s throughput (without scaling) | 01:26 |
| diddledan_ | or that might be an order of magnitude out | 01:27 |
| 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 | 01:38 |
| diddledan_ | there's illumination on the horizon | 03:16 |

| ujjain | hey, will linux servers crash at the leap second 2015 next week? | 14:02 |
| bigcalm | Tempting to be deviant....but I can't bring myself to be so | 14:04 |
| bigcalm | ujjain: no | 14:04 |

| 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? | 17:27 |
| popey | https://wiki.archlinux.org/index.php/Convert_a_single_drive_system_to_RAID | 17:32 |
| popey | seems needlessly complicated :) | 17:32 |
| popey | http://raider.sourceforge.net/ may be better | 17:33 |
| davmor2 | popey: it's archlinux ofcourse it is overly complicated :P | 18:05 |
| daftykins | hehe | 18:05 |
| 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 | 18:10 |
| popey | have a feeling it's just the connector | 18:11 |
| daftykins | ugh sandforce | 18:13 |
| 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 | 18:14 |
| 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 | 18:15 |
| 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 | 18:16 |
| daftykins | IME if the cabling is all fine, all wonky SSDs seem to behave after a nice secure erase | 18:17 |
| 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 | 18:19 |
| 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? | 18:20 |
| popey | yeah, hopeful | 18:21 |
| * popey goes to make food and stop watching this disk light flash :) | 18:21 | |
| 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 | 18:22 |
| daftykins | XD | 18:23 |
| davmor2 | popey: you byobu has a raid item right ;) | 18:26 |
| popey | bah | 18:40 |
| popey | its now dropped | 18:40 |
| popey | http://paste.ubuntu.com/11769256/ | 18:41 |
| popey | thats bad | 18:41 |
| daftykins | wowzer | 18:42 |
| daftykins | heh SSD in RPM shocker | 18:43 |
| 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 | 18:45 |
| popey | i have a plan | 18:46 |
| popey | one day | 18:47 |
| popey | Right, so we're gonna dd zeros on this original 4TB, right daftykins ? | 19:02 |
| * 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 | 19:06 |
| 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 | 19:07 |
| * 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 | 20:22 |
| daftykins | ^_^ | 20:23 |
| 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. | 20:24 |
| 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 | 20:25 |
| 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 | 20:26 |
| 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? | 20:27 |
| popey | yeah, it's just the time hassle | 20:28 |
| popey | I'd just rather not | 20:28 |
| 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 | 20:29 |
| daftykins | ah i was assuming it was there for the games alone | 20:31 |
| 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 | 20:32 |
| 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 | 20:33 |
