| troal01 | Ahh the joy of accidentally deleting your /home directory | 16:29 |
| SlimeyPete | I'd make some snide comment about backups, but tbh I can't remember the last time I backed up my /home | 16:43 |
| troal01 | Heh it's not the end of the world but damn it sucks having to rebuild your Firefox/Pidgin/DE/bash/what have you settings | 16:47 |
| troal01 | Oh and let's not forget evolution with the evolution-exchange plugin | 16:52 |
| troal01 | Takes forever to reload that :P | 16:52 |
| SlimeyPete | does that plugin provide access to shared calendars? | 16:53 |
| troal01 | Read yes, write no | 17:04 |
| troal01 | And it's slow as hell | 17:04 |
| troal01 | And it often takes a long time to check for new mail etc... Overall a pretty shitty experience :( | 17:05 |
| troal01 | the evolution-openchange plugin is going into gnome 2.26, hopefully that one will be better | 17:06 |
| troal01 | We'll know soon I guess | 17:06 |
| troal01 | Gnome 2.26 comes out next week :D | 17:09 |

| DarylM | troal01: 28 years ago I typed "rm -fr / usr/tmp/*" as root from a 1200 baud modem connected terminal. :O It wasn't pretty. (I had 100% backups however. Only 1 hour of down time) | 17:52 |
| pboro | :D | 17:53 |
| troal01 | Hahaha, darn those spaces DarylM | 17:56 |
| DarylM | Yup. In todays language, a n00b move | 17:56 |
| Alex| | always add "nohup" - makes things even more interesting :) | 17:56 |
| DarylM | This was a time in Unix-land where you could not remove an executable that was mapped into memory. As /bin is typically the first directory loaded, it is the first removed. Very interesting behavior in that stuff like "ls" and "ps" were gone, but items like "sh" and "getty" were still around. | 17:59 |
| troal01 | That's interesting, no such luck today though | 18:04 |
| DarylM | You DID have good backups, right? | 18:07 |
| troal01 | No backups :P | 18:20 |
| DarylM | http://www.apple.com/macosx/features/timemachine.html :) | 18:23 |
| grantc | rsync with lipstick | 18:23 |
| DarylM | Not exactly. | 18:23 |
| DarylM | Every version is available always. | 18:23 |
| DarylM | And each version appears in the directory tree just like it was from the original. | 18:24 |
| grantc | sccs with lipstick and foundation | 18:24 |
| DarylM | They used a very clever (and somewhat dangerous) trick. The augmented the kernel to allow hard links on directories | 18:25 |
| DarylM | and drive the process using the file system journals. Quite clever really. | 18:25 |
| DerMeister | That means if you delete a file you won't get any disc space back but even use some more? :) | 18:26 |
| Alex| | as in, where was it? Minix? Amoeba? | 18:27 |
| Alex| | every change in a file is a new file | 18:27 |
| DarylM | Yes. However this process is designed to use an external hard drive. Oldest backups are pruned if the drive fills up. Also note this is not an >archive< or offsite backup, but is designed to address precisely the problem troal01 just ran into | 18:27 |
| DarylM | Which is really the problem 99% of normal computer users really hit | 18:28 |
| DerMeister | I wouldn't want to use such a mechanism on a root file system. I think it's more usefull for "user data" | 18:28 |
| DarylM | Full disk restore. I can lose my hard drive and completely restore. | 18:28 |
| Alex| | and the last 1000 versions of /tmp, /var/run... :) | 18:29 |
| Alex| | probably better than nothing for backup-lazy people | 18:29 |
| DarylM | obviously some directories are pre-pruned LoL | 18:29 |
| DerMeister | Fortunately I didn't need any of my backups for a couple of years now. The only thing I remember is a backup of a Windows registry which saved my Win95 installation after I managed to link .exe files with Netscape Nanvigater. | 18:38 |
| DerMeister | Each time I tried to start an application Windows tried to open it with Netscape Navigator. But the only thing NN could do with that file was to download it to my hard disc... Wasn't quit usefull in this case, though... | 18:39 |
| *** grantc is now known as grantc_offline | 18:44 | |
| troal01 | Hehe timemachine, that's a neat trick... What about the overhead of it hough? | 18:51 |
| DarylM | Overhead is fair. On a decently equipped tower I don't notice (unless World of Warcraft is running....) but my Macbook Air definitely shows the I/O load. Not so intrusive as to make the machine hard to use, just noticeable. | 18:58 |
| DarylM | Since they are using the file system journals to determine what changed since the last backup, there is no need for a full file system scan. | 18:59 |
| troal01 | Yeah so it could be worse I suppose. Can't you do something similiar with LVM on Linux? | 19:01 |
| DarylM | Probably. there isn't any revolutionary technology here. Change lists, hard linked files and directories, and some lip stick :) | 19:03 |
| DerMeister | Somewhat off-topic, but still related to this topic: http://icanhascheezburger.files.wordpress.com/2009/02/funny-pictures-kitten-erases-your-hard-drive.jpg | 19:03 |
| DarylM | that is scary lol | 19:03 |
| troal01 | LOL! | 19:06 |
| troal01 | Anyone gotten this compilation error before? http://icanhascheezburger.files.wordpress.com/2009/02/funny-pictures-kitten-erases-your-hard-drive.jpg | 20:17 |
| troal01 | Err no | 20:17 |
| pboro | :D | 20:17 |
| pboro | ahaha | 20:17 |
| pboro | no, not lately! | 20:17 |
| troal01 | That wasn't the right message | 20:17 |
| pboro | obviously :) | 20:17 |
| troal01 | Essentially an issue with kerberos5 | 20:19 |
| troal01 | Having issues getting it copied from my VM | 20:19 |
| troal01 | http://ingres.pastebin.com/m5e7f65a4 | 20:24 |
| troal01 | Heh guess I should read better | 20:25 |
| troal01 | I'm missing a header | 20:25 |
| troal01 | Okay so my kerberos5 install doesn't have gssapi_generic.h, is it the same as gssapi.h? | 20:38 |
