| Kangarooo | whats name of programm controlling default browsers? in debian its x-www-browsers in ubuntu its gnome-browsers yes? and in xubuntu exo ? | 00:17 |
|---|---|---|
| moetunes | afaik it is exo yes | 00:19 |
| lamiska | heya, do you know if there is compression enable in btrfs in maverick? | 00:55 |
| Kangarooo | lamiska: btrfs is a filesystem? if yes i have no idea why compression of files would not work in some filesystem | 01:00 |
| Kangarooo | zip and tar and rar should work couse theyre just files.. | 01:01 |
| lamiska | no no | 01:01 |
| Kangarooo | and any filesystem can haz files | 01:01 |
| lamiska | btrfs has feature | 01:01 |
| lamiska | before it write files onto disk it compress them | 01:01 |
| lamiska | but defual it is disabled | 01:01 |
| lamiska | compress via zlib | 01:01 |
| Kangarooo | http://www.google.lv/search?hl=lv&q=btrfs+compression+enable&aq=f&aqi=&aql=&oq=&gs_rfai= | 01:02 |
| Kangarooo | i dont know | 01:03 |
| lamiska | whats that? lathuania, latvia? | 01:03 |
| Kangarooo | ouh yes hehe .. but results should be the same as in google.com | 01:04 |
| Kangarooo | latvia | 01:04 |
| lamiska | and can you tell me which filesystem is better for /boot partition | 01:04 |
| lamiska | i am from slovakia :) | 01:04 |
| Kangarooo | i was there 10y ago snowboarding and skiing | 01:04 |
| lamiska | ouch | 01:05 |
| Kangarooo | for boot im using xfs i think. and for all other i use ext4 | 01:05 |
| lamiska | i feel sorry for you :D | 01:05 |
| Kangarooo | why? | 01:05 |
| lamiska | services are horrible in my country | 01:05 |
| lamiska | Kangarooo: is it ok that i dont use swap? i have 4GB RAM, and never seen any usage of swap so i deleted it... | 01:08 |
| Kangarooo | services? i dont care about them.. all was ok where i was.. im using 1st drive /swap 1024mb.. 2nd partition all whats left for /home and last partition /boot 200mb xfs.. yes u can then advanced installation and no swap.. | 01:09 |
| lamiska | okey thank you very much | 01:10 |
| Kangarooo | since 1st part of disk physicaly is on inside its faster reading.. and last partition is on end of disck physicaly so its slower for reading.. since boot is needed not often then it can be last and swap if needed then is needed to be faster then better to have it as 1st.. | 01:11 |
| TheSheep | Kangarooo: the address on disk has nothing to do with physical location on modern disks | 01:27 |
| Kangarooo | aboud ssd i dont know.. that was about hdd | 01:28 |
| TheSheep | Kangarooo: I'm talking about hdd, there are several layers of mapping | 01:29 |
| Kangarooo | 4 yes? | 01:29 |
| TheSheep | Kangarooo: depends on the particular model | 01:29 |
| TheSheep | Kangarooo: but the logical geometry has nothing to do with physical anymore | 01:30 |
| TheSheep | Kangarooo: manydisks even remap dynamically | 01:30 |
| TheSheep | many disks* | 01:30 |
| Kangarooo | ive got this info about 1st beeing fater and last slower from one and somewhere read it too and noone ever has told me thats wrong even when told to some in #ubuntu | 01:30 |
| TheSheep | it was true 10 years ago probably :) | 01:31 |
| TheSheep | things got complicated since | 01:31 |
| TheSheep | I'm not up to date and familiar with those things myself, I just know that it's much more complex now and there is no simple rule | 01:32 |
| Kangarooo | thouse layers u mean platters yes? | 01:33 |
| TheSheep | no | 01:33 |
| TheSheep | I mean logical layers | 01:33 |
| TheSheep | as in mapping disk position to address, then mapping those addresses to internal representations, then maping those representations to logical geometry as seen by the operating system | 01:34 |
| TheSheep | it's like a several levels of emulation | 01:34 |
| TheSheep | the disk that is actually accessed by the operating system is a virtual disk, emulated by the disk's firmware | 01:35 |
| TheSheep | and has little to do with physical locations of the bits | 01:35 |
| Kangarooo | ok i found something here http://www.tk.k12.mi.us/vm/scenario1.jpg | 01:36 |
| TheSheep | that's higher level | 01:36 |
| Kangarooo | ok but then is it possible to get if i know if hdd has 4 platters then xx gb / 4layer = size of platter so i could make 2/5 of 1 platter size to be swap then 3/5 of first rest size + size of 2nd and 3rd plater (witch are the same) + 9/10 of last platter size to be home then 1/10 last platter last left size to be boot. then at least boot will be slowest and swap fastest and some of home parts will be faster and slower and medium speed.. | 01:41 |
| Kangarooo | couse home will be last par of 1st plater all of 2 and 3 and start of 4th plater | 01:42 |
| TheSheep | first, the tracks closer to the hub are recorder with lower density | 01:43 |
| TheSheep | second, the internal software of the disk remaps whole chunks of memory to different places | 01:43 |
| Kangarooo | ah maybe that logical mapping does that so that all whats in 1st partition is in all 4 platters in inside of them and last partition is on outer side on all 4 platters? | 01:43 |
| TheSheep | sometimes even dynamically | 01:43 |
| TheSheep | for example, modern disks have a number of extra blocks that are used to store data from damaged disk areas | 01:44 |
| TheSheep | so even if some blocks get damaged, the disk still has the same capacity and is continous | 01:44 |
| TheSheep | (or seen as continous by the computer hardware) | 01:44 |
| TheSheep | most disk actually are manufactured with some number of errors on them already | 01:45 |
| TheSheep | because it would be too expensive to make error-less ones | 01:45 |
| TheSheep | then they are tested and the faulty blocks are remapped | 01:45 |
| TheSheep | there is also interlacing | 01:46 |
| TheSheep | for speed | 01:46 |
| TheSheep | so it may be like 1 5 2 6 3 7 4 8 | 01:46 |
| TheSheep | so that when you read continous area, it actually reads every second sector | 01:47 |
| TheSheep | there are many such tricks, all together | 01:47 |
| TheSheep | different for different disk models | 01:47 |
| TheSheep | in the end, the only way you can tell which part of a disk is faster is by actually testing it | 01:48 |
| Kangarooo | maybe its just faster.. 3 days ago had 3 day meetings with inventors. one was with solution for scintilators witch are photon seeing sensors used in computer tomography. old method makes 1/1day and usable is only 15% of produced scintilators. his new method makes 1/10min and 80% usable. bigger costs but at end product 30x times cheaper. but theres no way to control photon way once theyr away as in hdd.. but also interesting problem witch | 01:51 |
| Kangarooo | so for hdd maybe thats only best method- to make bad block info movability to new block | 01:52 |
| Kangarooo | witch programm makes partition speed? | 01:54 |
| Kangarooo | should i do it with live cd? | 01:54 |
| TheSheep | no idea, I'm sure there are some benchmark programs | 01:54 |
| TheSheep | I don't think the difference is so big anymore | 01:55 |
| TheSheep | remember that there are also several levels of cache, both in the disk and in the operating system | 01:55 |
| TheSheep | and some predictive algorithms in the disk itself | 01:55 |
| Kangarooo | yes there is i also was reading once about one. xubuntu helps older get still fast. info about hdd partitioning would also be good for them if detected that their hdd has exact mapping | 01:57 |
| TheSheep | I don't think xubuntu works on disks *that* old :) | 01:57 |
| TheSheep | they were like 20MB big | 01:58 |
| Kangarooo | ouh | 01:59 |
| Kangarooo | ok sudo hdparm -Tt /dev/sda1 and sda7 | 02:02 |
| Kangarooo | i did it 2 times for sda1 and sda7 and results were changing oly for about 1% | 02:02 |
| Kangarooo | /dev/sda1: Timing cached reads: 368 MB in 2.00 seconds = 183.89 MB/sec Timing buffered disk reads: 52 MB in 3.07 seconds = 16.91 MB/sec | 02:02 |
| Kangarooo | /dev/sda7: Timing cached reads: 366 MB in 2.00 seconds = 182.77 MB/sec Timing buffered disk reads: 74 MB in 3.06 seconds = 24.18 MB/sec | 02:02 |
| Kangarooo | for timing bufered reads only decimal numbers changes | 02:04 |
| Kangarooo | /dev/sda5: Timing cached reads: 372 MB in 2.01 seconds = 185.41 MB/sec Timing buffered disk reads: 58 MB in 3.09 seconds = 18.80 MB/sec | 02:06 |
| Kangarooo | /dev/sda6: Timing cached reads: 394 MB in 2.00 seconds = 196.84 MB/sec Timing buffered disk reads: 74 MB in 3.03 seconds = 24.40 MB/sec | 02:06 |
| Kangarooo | so that makes 1st parts slower.. since i did partitioning not usualy way i have sda1 5 6 7 | 02:07 |
| Kangarooo | u should also write article couse thats interesting topic. also here i found one http://partition.radified.com/ | 02:14 |

| fumanchu182 | Late evening guys, I am having an issue with Netbeans and one of its shortcut keys being captured by the Workspace utility. Apparently Alt+Insert = Adding a new workspace but it is also a crucial component of Netbeans. I cannot configure it in netbeans so how would I disable it in Xubunut? | 03:07 |

| fusion_ | i can't login, whenever i login to my account my screen flashes and then i get back to the login screen | 06:16 |
| fusion_ | it happened after i applied a patch to fix the display problem | 06:16 |
| ubuXubu | sudo dpkg-reconfigure -phigh xserver-xorg | 06:17 |
| fusion_ | then what? | 06:18 |
| ubuXubu | This should restore your original video settings. | 06:19 |
| fusion_ | after doing startx, it shows - "No protocol specified" | 06:19 |
| ubuXubu | to restore xubuntu to its original state you could try this Press alt+F2.In that type xfwm4 --replace. | 06:20 |
| ubuXubu | http://ubuntuforums.org/showthread.php?t=815738 | 06:21 |
| fusion_ | ok, lemme try | 06:22 |
| ubuXubu | i can't say i have any experience actually doing it, i just read about it. | 06:22 |
| ubuXubu | i have never had that problem yet. | 06:22 |
| fusion_ | is it a cli command? because i cant use GUI? | 06:22 |
| ubuXubu | well the 1st one is a terminal command | 06:23 |
| fusion_ | nope doesn't work | 06:23 |
| ubuXubu | do u have a xubuntu installation disk | 06:23 |
| fusion_ | i'm sick of the ubuntu's diplay problem in the intel 82845G video card. | 06:24 |

| pythonian4000 | Hey, I have recently upgraded to Xubuntu 10.10, and have just tried playing some video - the video plays but with no sound. I was also getting pa_stream_writable_size() failed on some videos. | 06:27 |
| pythonian4000 | I tried resetting the permissions of everything in my home dir, and uninstalling and reinstalling gstreamer0.10-pulseaudio, but nothing. I have also tried VLC which has its own drivers - still no sound. | 06:28 |

| Renegade15 | good evening. Is there any way to install from CD over an existing installation to upgrade the installed system without losing data, especially without funny business like deleting existing home directories? | 20:51 |
| knome | Renegade15, when you insert the cd, you should get a prompt that says a new media with a package repository is inserted, and what you would like to do with it | 20:51 |
| Renegade15 | the installed system would probably have to give me more than a crappy excuse for a terminal for that | 20:52 |
| knome | excuse me? | 20:52 |
| knome | a prompt dialog, not a terminal | 20:53 |
| Renegade15 | all I'm getting in the installed system is a shiny white terminal which will only work if I hover the cursor (hidden in the abyss that is the rest of the screen) over said terminal | 20:53 |
| Renegade15 | so no chance for any prompts | 20:54 |
| knome | Renegade15, well you should be able to add the cd to the sources.list manually, if nothing else. | 20:55 |
| Renegade15 | that would be awesome | 20:55 |
| Renegade15 | any particular path format? | 20:55 |
| knome | Renegade15, apparently see apt-cdrom -tool | 20:56 |
| knome | (i have no idea how that works, but...) | 20:56 |
| Renegade15 | I see...would it matter whether I'm using the standard or alt CD? | 20:56 |
| knome | no, that shouldn't make any difference regarding this situation | 20:57 |
| Renegade15 | alright | 20:57 |
| Renegade15 | hmpf | 21:03 |
| Renegade15 | it looks good at first, but then it says it can't find the individual files | 21:03 |
| Renegade15 | (this is *after* it already added the CD to the list of sources and extracted the package lists from it) | 21:03 |
| Renegade15 | alright, is there a way to force aptitude to ignore a hash mismatch? | 21:39 |
| jonathan | i was wondering if there is any way i can permanently get around the executable bit on windows programs with wine | 21:43 |
| knome | jonathan, what is the problem? | 21:47 |
| knome | Renegade15, i don't think so really. | 21:47 |
| knome | Renegade15, is network upgrade out of question? | 21:47 |
| Renegade15 | network upgrade wouldn't work because the POS complained about the "encodings" module of python being missing | 21:47 |
| Renegade15 | needless to say, a python-encodings package doesn't exist, and reinstalling python and python-central did nothing | 21:48 |
| Renegade15 | tried python-apt, too | 21:48 |
| Renegade15 | did nothing | 21:48 |
| jonathan | hmmm, because i'm having trouble where i cant set the exe files to be executable | 21:48 |
| Renegade15 | chmod +x? | 21:49 |
| knome | jonathan, at least from terminal 'chmod +x /path/to/exe' | 21:49 |
| jonathan | can i set that command into a launcher? | 21:49 |
| knome | jonathan, you should only need to do that once per file | 21:50 |
| jonathan | oh, k | 21:50 |
| knome | jonathan, after that, it's marked as executable | 21:50 |
| jonathan | i'll try that, 1 sec | 21:50 |
| Renegade15 | alright...for the moment, it pretends to be working | 22:03 |
| Renegade15 | I somehow beat aptitude into submission, and thanks to having the cd as source, I don't even have to download the majority of packages | 22:03 |
| Renegade15 | let's see what it finds to bitch about this time -_- | 22:03 |
