[00:34] QUESTION: Is there some classes here? or am I late? [00:36] XuMuK: Check out http://is.gd/8rtIi [00:52] nhandler, thanks [00:52] Hi === yofel_ is now known as yofel === sano is now known as Guest57011 === MTecknology is now known as MTeck-ricer [05:14] Hello there === Mobe_ is now known as Mobe === pythonlova is now known as apachelogger [08:24] userdays3: in just over an hour [08:24] Oh I see === userdays3 is now known as ech0tk === Sodlig is now known as ech0tk === Sodlig is now known as ech0tk === ChanServ changed the topic of #ubuntu-classroom to: Welcome to the Ubuntu Classroom - https://wiki.ubuntu.com/Classroom || Support in #ubuntu || Upcoming Schedule: http://is.gd/8rtIi || Questions in #ubuntu-classroom-chat || Event: Ubuntu User Days - Current Session: Introduction To Ubuntu User Days - Instructors: nigelb, pleia2, cjohnston, _marx_, Pendulum [10:30] Hello everyone, and welcome to our second Ubuntu User Day! https://wiki.ubuntu.com/UserDays [10:30] To get things started, who is here for this and where are you from? [10:30] Hello [10:31] I'm here and I'm from Sweden [10:31] hello, I am from the UK [10:31] I am from Sri Lanka [10:31] * pleia2 waves to everyone from middle-of-the-night California ;) [10:31] Hi ya'll and I'm from the US/Illinois [10:32] \o from india [10:32] <_marx_> north carolina [10:32] Hi from Fiji [10:32] Hi from South Africa :) [10:32] hiya from Connecticut [10:32] howzit! South Africa [10:32] I'm from Belgium [10:32] Hi from Australia :) [10:33] great, sounds like we have quite a diverse crowd :) [10:33] * cjohnston wants to go to kermiac's house [10:33] Belgian as well [10:33] cjohnston: for the kangaroos? [10:33] Marceau : cool :) [10:33] sure [10:33] lol [10:33] cjohnston: feel free to come over & have a beer mate.. yeah pleia2, we've got roo's out the back (but they're asleep right now) [10:34] hehe [10:34] Alrighty, So, what is this day all about anyway? [10:34] I am from England [10:34] User Days was created to be a set of classes offered during a one day period to teach the beginning or intermediate Ubuntu user the basics to get them started with Ubuntu, including: [10:34] kermiac: I don't drink but i'll take some coffee if ya got it [10:34] Chennai, India [10:34] pleia2: It is about getting users encouraged into ubuntu [10:34] ??? [10:34] Basic Ubuntu Installation and Setup, Partitioning 101, Package Management Basics, Getting involved in the Ubuntu Community, Command Line Basics... [10:35] MichealH: that too! [10:35] ...and more! For our full schedule head over to https://wiki.ubuntu.com/UserDays [10:35] There are are 10 minutes remaining in the current session. [10:35] The User Days Team has worked with Local Community Teams (LoCos), the Ubuntu Beginners Team, Ubuntu Classroom and the Ubuntu Community Learning Project and others within the wider community to bring this day to you. [10:35] User Days was born out of a discussion at the Ubuntu Developers Summit in November 2009 regarding Ubuntu Open Week not being targeted enough at users. [10:36] Now, we will give you a quick rundown of how today will work: [10:36] Each hour, a presenter will be giving a class in this channel, #ubuntu-classroom [10:36] Pendulum: Can we have a link for classroom schedule [10:36] https://wiki.ubuntu.com/UserDays [10:36] During the classes, #ubuntu-classroom will be moderated (+m), meaning that only the instructor and hosts will be able to speak in that channel. [10:36] Thanks ech0tk [10:36] Please hold all discussion about the class in #ubuntu-classroom-chat [10:37] If you have a question during the class, please ask in #ubuntu-classroom-chat with the prefix QUESTION: for instance you may say: [10:37] QUESTION: How do you uninstall a program? [10:37] After each session (as soon as our volunteers can), we'll be posting logs on the wiki, so be sure to check back to https://wiki.ubuntu.com/UserDays if you missed anything. [10:38] Logs will also be automatically posted at http://irclogs.ubuntu.com at the end of each hour [10:38] <_marx_> Since you're already here, you know how to participate, but in case you have a friend you'd like to invite, you can find some help on the Joining In wiki page: https://wiki.ubuntu.com/UserDays/JoiningIn [10:38] <_marx_> You may have seen articles about the Lernid application which is designed for learning events such as this, you can certainly try out Lernid for User Days: https://wiki.ubuntu.com/Lernid [10:39] <_marx_> In Ubuntu 10.04, Lucid, to use lernid you just want to install the "lernid" package. [10:39] <_marx_> Finally, before we get to some general Q&A in this introduction session, a big thanks to everyone who made this day possible :) [10:39] <_marx_> So, does anyone have any general questions about the day? [10:39] Yes, I do [10:40] <_marx_> ask away Lilspanyol [10:41] The next session will be quite hard to follow, ah? [10:41] Installing Ubuntu [10:42] But during the installation, I can't look at the IRC chat because I only have acces to my laptop at the moment [10:42] access [10:42] Lilspanyol: You wont' be installing at the time of the session. It's a basic guide [10:42] Lilspanyol: do you have virtualbox or vmware? [10:43] yup, thanks, I didn't consider that [10:44] Just for the sake of the class I'll be following it, because back when I installed Ubuntu Hardy, I messed up because of installing on the wrong partition [10:45] any other questions about the day? [10:48] pleia2: I dont think so [10:48] I don't. I hope to be able to follow some classes, but I'm having a busy day and it's so hot in belgium today [10:49] Lilspanyol: You can read stuff later on, there will be logs as well. [10:49] Lilspanyol: Its rather hot here as well [10:49] its always hot in here :D [10:51] At the end of your day, please take the time to fill out our survey! http://www.surveymonkey.com/s/FJ697T7 [10:52] is there a schedule somewhere - was expecting to see it in the topic [10:52] http://www.ubuntu-user.com/Online/Blogs/Amber-Graner-You-in-Ubuntu/Ubuntu-User-Days-Scheduled-for-July-10-11-2010 [10:52] sometimesworks: https://wiki.ubuntu.com/UserDays [10:53] got that link in the weekly Ubuntu Newsletter [10:53] the schedule in the topic works too [10:53] Lilspanyol: Maybe you missed my reply to installing in classroom chat, so i'll do it in here as well. [10:53] sometimesworks: https://wiki.ubuntu.com/UserDays [10:53] Lilspanyol: Theres also a basic install guide in the Ubuntu Manual by the way and i'll sometimes help people get set up with an install with a seperate /home from #ubuntu [10:53] <_marx_> you can just type /topic to see the topic [10:53] !manual [10:53] The Ubuntu Manual will help you become familiar with everyday tasks such as surfing the web, listening to music and scanning documents. With an emphasis on easy to follow instructions, it is suitable for all levels of experience. http://ubuntu-manual.org/ [10:53] pleia2: didn't see the odd link - was expecting a wiki one :) [10:54] _marx_: I know ;) [10:54] i'll go to the classroom-chat channel ,see ya there guys [10:54] Lilspanyol: You are already in there, but yeah see you there :) [10:55] There are are 5 minutes remaining in the current session. [10:56] Quick Question: How 'basic' is this user day? For the users who hasn't seen Ubuntu before or for the guys who used it for a couple months [10:56] ech0tk: yes... [10:56] ech0tk: we start off with installation :) so it covers both [10:56] <_marx_> both would fit i think [10:56] Alright [10:56] ech0tk: For newbies mainly, but some of it could be still quite interesting for us more expereinced users. [10:57] ech0tk: Of for peeps like me who have been here for 4 years, refreshing on basics [10:58] ech0tk: (Well I don't know if you have used it for a while) === ChanServ changed the topic of #ubuntu-classroom to: Welcome to the Ubuntu Classroom - https://wiki.ubuntu.com/Classroom || Support in #ubuntu || Upcoming Schedule: http://is.gd/8rtIi || Questions in #ubuntu-classroom-chat || Event: Ubuntu User Days - Current Session: Basic Ubuntu Installation and Setup - Instructor: zkriesse [11:02] Zach Kriesse is a Mentor with the Ubuntu Beginners Team and Lead of the Wiki Focus Group. He's also a soon to be college student for an Associate of Arts degree (hopefully) in the Medical Field. An advocate of OpenSource software and the Ubuntu/Linux OS. [11:04] Ok so Basic Installation and Setup [11:04] While that topic may seem a bit daunting at first, it's much easier than it sounds [11:05] So, What is Ubuntu? [11:05] Ubuntu is a free, open-source, operating system that anyone can use and edit. And unlike Windows which only supports the NTFS and FAT file systems, Ubuntu supports a garden variety of file system formats. Ubuntu [11:05] Any questions before i continue? [11:06] Ok, Now a question that is good to ask of yourself is "Why Ubuntu? Why Windows?" [11:07] While there are certain aspects of Windows that you may find attractive, you must remember that Ubuntu and Linux in general is Open-source and a Community wide effort. Which means that not only is the workload of supporting the User spread out it's also much more friendly than say, Windows Tech support [11:08] Now, Types of Linux [11:09] What are they? While you may say, "Oh there's more than one? How on earth do i choose!" It's actually a bit easier to choose one than it seems [11:10] OpenSuse, Lubuntu, Red Hat, Fedora, Debian, these are all versions of Linux. But one of the more notable and somewhat easier to understand is Ubuntu [11:11] Ok, so Ubuntu. How to start using it [11:12] The first thing you should probably know is that there are two type releases of Ubuntu [11:13] One is the LTS type release and the other is a standard release [11:13] Now I'm sure you're wondering, What is LTS? What does it mean? [11:14] Well LTS Stands for "Long Term Support" which means that there will be a longer time of support and security updates for that particular version [11:14] Any questions before i move on? [11:15] No questions? Ok, moving on [11:15] Installation [11:16] Ok, to install Ubuntu first you're going to need a few things. One, is your computer, two: you'll need an Ubuntu LiveCD, and three: a cup of coffee [11:17] Now, what is the LiveCD? Well what the Live CD is, simply explained its the entire Ubuntu OS including all of the pertinent data to run a complete Operating System [11:19] Now to install Ubuntu you'll need to stick in that Live CD and boot your system (turn it on) whilst the CD is in your pc [11:21] you'll be presented with a few different options on boot up. One is, "Try without installing" or something to that affect. The other is "Install Ubuntu" The First option is recommend [11:23] If you go with the first option, (Try without installing) the Ubuntu Desktop will be booted up off of the CD and displayed before you on your monitor [11:25] Apologies folks...connection troubles today [11:26] Now, while in the Ubuntu OS, you have some options [11:27] You can either try it out and then install and wipe the system clean of your previous OS, you can continue trying it and then just shut it down, or you can install it Side-by-side with your first OS [11:28] Now, to install if you chose to try it first you'll notice a small icon on the desktop which says "Install Ubuntu" [11:29] Double click that "button" and it will start the install process. [11:30] The install process is fairly simple, you'll be presented with a menu where you'll first pick your language, your time (so the pc clock is correct) and then some other pertinent info such as user name and your password for the pc [11:32] After you enter all that you'll then have the option of where to install Ubuntu. You can either install it over the previous OS (meaning it will do a full wipe of everything) or side by side using the available space [11:34] If you choose the first option, Ubuntu will be the only OS running on the system. If you choose the second one, when you boot (turn on) your system you will have the option of picking either the first os or the second which would be Ubuntu [11:35] So, choose your installation type, and then click ok [11:36] Then the install process will start and all you have to do is wait until it finishes. Usually the install process takes about 25 to 30 minutes depending upon your system's capabilities. [11:37] oneDoRa75 asked: If I dual boot windows and ubuntu, will it harm my hdd? [11:38] No, doing a Dual Boot of Ubuntu and Windows will not harm your hdd. Unless you do something very, very, wrong you'll be just fine. === BlackZ_ is now known as BlackZ [11:40] Ok so after the install process is finished the system will ask you to shut down and restart. When it does you'll be presented either with your new Ubuntu install (If you chose to install it by itself) or you'll be presented with the GRUB menu and from there you'll be able to choose to either boot into Ubuntu or your other OS (windows is assumed) [11:41] Now if you happened to do a dual boot of Ubuntu and Windows, you will be able to mount your windows partition whilst using Ubuntu [11:42] But the only to identify the drive is via its size. If you have a large hdd that shouldn't be an issue though. [11:43] Now if you want to choose to be able to mount the windows drive at your discretion it's a simple matter of doing so when in Ubuntu [11:43] xifer asked: can you dual boot a mac computer? [11:44] Depending upon the mac system yes it shouldn't be an issue. [11:44] The steps are to have OSX installed first and then install Ubuntu afterwards [11:45] Ok, any more questions? [11:45] I'm trying to not put too much on you guys at once [11:46] No questions? None at all? [11:48] Ok so no questions? Ok moving on then [11:48] got about ten minutes left [11:49] So, now that you've installed Ubuntu, what now? [11:50] Lilspanyol asked: Can I make GRUB autoboot windows without the menu showing up, so that when i press the 'on' button of my laptop, i press a key and GRUB shows up [11:50] There are are 10 minutes remaining in the current session. [11:51] Lilspanyol: there should be a way to do that but for more info look at [11:51] !grub2 [11:51] GRUB2 is the default Ubuntu boot manager since Ubuntu 9.10. For more information and troubleshooting for GRUB2 please refer to https://help.ubuntu.com/community/Grub2 [11:52] Sorry that I can't provide more info than that at this time [11:52] philinux asked: Can you mention the importance of doing backups before attempting a dual boot [11:53] Yes, BIG THING...please take heed. BEFORE you even attempt to do a dual boot of Ubuntu and Nix OS please do a full backup before you do anything else [11:53] purvesh asked: which is the Best way to recover grub, because if i'll repair windows then it will remove grub so i cant access to my Linux [11:54] To get ALOT of info on recovering Grub/Ubuntu after installing Windows please take a look at https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows [11:54] I'd try and do a bit more answering to that but i've got five minutes left [11:55] Ok so that's really all i got...sorry if it wasn't all you expected [11:55] There are are 5 minutes remaining in the current session. [11:56] So, any more questions? [11:56] xifer asked: what to da after install to get dvd etc working? [11:56] Ah good question [11:57] For DVD's please see https://help.ubuntu.com/10.04/musicvideophotos/C/video-dvd.html [11:57] IF ya got a question toss it at me! [11:58] I'll only be able to give a link(s) though...got two minutes left [11:58] philinux asked: Does lernid kee a log of this? [11:58] I'm pretty sure it does... [11:59] ok that's it! [11:59] Thanks for listening to my monologue! === ChanServ changed the topic of #ubuntu-classroom to: Welcome to the Ubuntu Classroom - https://wiki.ubuntu.com/Classroom || Support in #ubuntu || Upcoming Schedule: http://is.gd/8rtIi || Questions in #ubuntu-classroom-chat || Event: Ubuntu User Days - Current Session: Partitioning 101 - Instructor: AlanBell [12:01] Alan Bell is a director of The Open Learning Centre, a software consultancy company in the UK that works exclusively with Free and Open Source software. Alan and his family all use Ubuntu, however the chickens in the garden seem to prefer Kubuntu. [12:01] hi all [12:01] This session is about partitioning, and general arrangements of hard drives. Partitioning is a way of dividing up the storage on a hard drive so you can do different things with different bits of it. [12:02] Feel free to ask questions as we go along, I am happy to answer anything about partitioning and also anything about chickens. [12:02] and yes, my chickens really do use Kubuntu http://people.ubuntu.com/~alanbell/chicken.png [12:02] Partitioning is a bit of an advanced topic and was originally scheduled at the end of the user day, but as that 03:00 UK time I figured I would probably pass out before it started so got it shifted. [12:03] I don't want to start by putting off my audience, but if you are looking to install Ubuntu for the very first time this session may be overkill, just run through the standard installer and it will make sensible default choices for you. [12:03] It will either create one big partition for your whole disk or if you have another operating system installed it may offer to resize it and install alongside. [12:04] This session is for those who want to arrange their disks in a more specialised way, and to teach some of the history and low level background to the terminology around partitioning. [12:04] So why might you want to do anything different with your partitions? [12:04] The most common reason is to separate /home from the rest of the operating system. [12:05] abhi_nav: I guess they are khickens or something yes! [12:05] That means that with a bit of care you can totally nuke from orbit the rest of the disk and reinstall ubuntu or another distro, or any UNIX like operating system that wants to see a /home partition. [12:06] You can have a dual boot system allowing you to boot into for example Ubuntu and Debian but both operating systems having the same /home partition. [12:06] Just remember a load of settings live in /etc along with the user passwords (unless you are using an external directory such as LDAP to authenticate against) /home isn't quite everything that is important. [12:07] It could be that you want *Extreme* performance! [12:07] In theory, if you create one partition of about a quarter of the total size of the drive that should be on the outer rim of the platter and spinning faster and all the data on it closer together so the read head doesn't have to move much to get to any given bit of data. You waste 75% of the drive, but hey it might be a bit faster! [12:07] If anyone actually tries that I would be interested in some benchmark results to see if it really makes any difference whatsoever! [12:08] that is called short stroking. Seems a bit excessive to me. [12:08] You could also have multiple file systems optimised for different use patterns, for example log files and couchdb databases only ever get appended to so you might not want a filesystem that is optimised for lots of small dynamic files for that bit of your data. To be honest I think that is over-thinking the situation again. === tech__ is now known as purvesh [12:09] partitions impose a rather firm size limit on their contents, you can take advantage of this, particularly on a server by putting things that grow in separate partitions from things that get upset if the disk runs out of space [12:10] so putting /var/log in a partition means that if it fills up the logging breaks, but other stuff should carry on [12:11] anyone think of other reasons to use a more complex than default partition system? [12:11] kbmonkey: yes, we will come on to drive letters and the numbering system in Ubuntu [12:12] JR0cket76 asked: does a more advanced partitioning scheme make backups easier or harder? [12:12] yay, got classbot working [12:13] hmm, good question [12:13] generally you back up mounted filesystems rather than partitions [12:14] so I don't think the number of partitions would make that much difference from a backup perspective [12:14] abhi_nav asked: I have ubuntu installed on one single partition. can i separate my /home now? with as possible as less effort? [12:15] yes you can, probably with more effort than would be desired! [12:15] basically you have to copy /home to another partition, then mount the other partition on top of where /home was [12:16] abhi_nav asked: I am wishing for distro hopping. so do you recommend me to make my /home separate now at this point? because as I said now alrady my ubuntu is setup very nicely and it is working very good. I dotn want to ruin. it. === xfact is now known as xfact|afk [12:17] yeah, not a bad idea, if you actually want to work and access your stuff on multiple distros [12:17] however do watch out for stuff like different versions of firefox getting upset with the shared .mozilla area and so on. [12:18] ok, lets carry on a bit [12:18] Lets look at what partitions really are. [12:18] A disk is a spinning hunk of magnetised metal called the platter, with a read write head floating just above the surface which can move back and forth along a radius of the circular platter. [12:18] There are normally multiple platters stacked on the same axle or spindle, and multiple read/write heads. The ring of the platters with the heads at a certain position is called a cylinder [12:19] so cylinders are kind of the bit of disk traced out by the heads as the disk spins, remember I mentioned putting data in the outer 25% of the disk, that is what cylinders are. [12:19] sebsebseb asked: Ubuntu and other distros have Ext4 now as the default file system. However does it really matter what file system is used for / or seperate /home or seperate /boot for example? [12:19] don't think so for those ones [12:20] although actually a transaction log of a journaled filesystem on a really small partition like /boot might be an unneccessary overhead [12:21] kcj1993: apparently the outer portion of a disk is faster, not entirely sure I believe it. [12:22] sebsebseb asked: Whats a transaction log? Also I think that people normally go with Ext2 or Ext3 when doing seperate /boot, rather than Ext4, because of unneeded features? [12:23] ext4 is a journaled filsystem, which means it writes stuff before it commits it so there is never a half written file hanging about if the power gets cut [12:25] each save is a "transaction" I am not sure that ext4 actually calls it a transaction log though, I may be getting my terminology confused with more database type journaling [12:26] anyhow, the outside 512 bytes of data, before the first partition is called the Master Boot Record [12:26] Inside this little nugget of data there are four 16 byte areas, into which is crammed a load of information about the 4 possible partitions. [12:26] You may be thinking that four partitions is a pretty low limit, and you would be right [12:26] that dates back a *long* time, most limits in the PC architecture from the past have been removed, but that one is in a pretty awkward place, there really isn't room in the master boot record for anything more sophisticated [12:27] The way we get more partitions is to use the first one to put stuff in, but use one of the others (generally the second one) as a holder of the "extended partitions" [12:27] So partition 1 is used as a partition, i.e. for storing your stuff in. [12:27] partition 2 holds the extended partitions [12:27] 3 and 4 are not used (normally) [12:27] partitions 5,6,7 . . . are the extended partitions that live inside partition 2 [12:28] lets see what that looks like for real [12:28] from an Ubuntu terminal prompt try typing [12:28] sudo fdisk -l /dev/sda [12:28] you should get something like this [12:28] http://paste.ubuntu.com/461528/ [12:29] ok, so lets go through this bit by bit, why did we say "sudo fdisk -l /dev/sda" [12:29] sudo allows us to run dangerous commands, stuff that can mess up other users of the computer [12:30] Unix like systems are designed to support many users at once and prevent them from hurting each other (Unix came from universities where they let students use them so users are presumed to be clever, clumsy and sometimes hostile!) [12:30] Messing with the partition table on a shared computer could really spoil someone's day, so we use sudo (but don't worry we are not going to break anything today) [12:30] fdisk is a command for manipulating "fixed disks" and the partition tables on them [12:31] -l tells it to list a partition table (today "look but don't touch" is the rule, we don't want to break anything) [12:31] /dev/sda is the device that we want it to examine, /dev is where all the hardware devices live [12:32] sd means it is a SCSI or SATA disk (as opposed to the old IDE disks which started with "hd") [12:32] and "a" means it is the first physical disk [12:32] b would be the next one and so on [12:32] if you plug in a USB memory stick that will be given a letter the same way [12:33] kbmonkey asked: How can I see a list of drives in my system? === tech__ is now known as purvesh_ [12:35] if you do fdisk -l without specifying a disk it will list all that it knows about [12:35] you can see them all in /dev as well === xfact|afk is now known as xfact [12:35] and in /dev/disk if you want to see the UUID of each one [12:36] ok, so looking at my disk http://paste.ubuntu.com/461528/ what is it telling us? [12:36] lines 4-9 are various stats about the size of the disk, this is a 320GB disk [12:36] Gryllida asked: why didn't you mention that I need to defragment the hdd before setting the dual boot? [12:37] err, you don't really. It is a decent time to to it I suppose [12:37] you should defragment before resizing a partition, because that shuffles all the data up together so it can be shrunk [12:38] abhi_nav asked: does frequent partitiong the harddrive decreases its life and/or performance? or in other word how I should not do partitioning that will damage my hdd? [12:38] abhi_nav asked: what is UUID? [12:38] it won't change the life or performance of the drive [12:39] I guess frequent partitioning increases the probability that you will accidentally delete the wrong partition! but beyond that it should be fine. [12:40] a UUID is a big long number that uniquely identifies a disk, things are moving to referring to those more so they get it right if you plug the disks in a different order [12:40] so the fstab file (which I will mention a bit later) can refer to disks by their device name or UUID [12:41] sebsebseb asked: Ok, but only Windows partitiosn get defragmented first in that case? I mean Linux partitions don't tend to get defragmented if ever? [12:41] abhi_nav asked: you said that it wont chante the life of drive? so in other words can you say that i can partition a hdd with any number of times with any filesystem? still not damaging it? [12:41] dnielsen asked: What optimizations does Ubuntu have in place to accommidate detection and correct partitioning of SSD cards, e.g. a swap partition on an SSD is a bad idea (or so sayth the mighty Dave Jones) [12:42] ok, firstly yeah linux doesn't have the defrag problems that windows does. I think that is mostly because it doesn't get so upset when things get fragmented === tech__ is now known as purvesh_ [12:43] yeah, partition away, don't worry about it damaging stuff physically, it is just data . . . however. . . . [12:43] the next question was about swap on SSD [12:44] and yes, there may be an issue on some SSD or flash drives with constant writes and reads from the same point of the disk === purvesh__ is now known as purvesh [12:45] I am not aware of anything that prevents you doing that in Ubuntu (the operating system doesn't really know much about whether a drive is ssd or hdd physically) [12:45] but yeah, swap on SSD might be bad for the SSD. [12:46] That said, it would be a pretty damn good swap area. [12:46] dnielsen asked: Specifically I would like to eventually replace all my computers HDD drives with small fast SSDs and rely on network and cloud storage, but I am worried that Ubuntu currently won't correctly setup for SSD cards ad thus will cause additional unneeded wear [12:46] Marceau asked: Is scratch really necessary in Linux? Is it the same as virtual memory/paging? [12:47] well I don't think modern SSDs have the problems that the early ones did, I think the drive controllers shuffle stuff about to prevent that [12:48] when you install ubuntu you can specify whether you want swap or not. If you have plenty of memory you don't need it. [12:48] ok, so looking at my disk http://paste.ubuntu.com/461528/ what is it telling us? [12:48] 11-14 is the partition table, this is a default install of Ubuntu [12:48] line 12 is the details of /dev/sda1 that is the device that corresponds to partition 1 of the physical disk /dev/sda [12:48] It is a bootable partition, the little asterisk tells us that [12:48] next is the start and end positions of the partition, in cylinders [12:49] next bit is the ID, in this instance 83 which is just a number corresponding to the fact that this partition is going to be used for a linux filesystem [12:49] as opposed to ntfs or fat or one of a couple of hundred of other filesystem possibilities [12:49] line 13 is /dev/sda2, this is used for nothing other than as a placeholder for the extended partitions [12:49] line 14 is /dev/sda5 which is my swap partition [12:50] so that is why you end up with sda2 that seems to do nothing [12:50] and sda3 and 4 which are missing [12:50] There are are 10 minutes remaining in the current session. [12:50] Gryllida asked: why is it '/dev/'? what does it stand for? [12:50] matematikaadit asked: how much memory that must we have in the case we don't want to use swap? [12:51] dev stands for devices [12:51] everything in linux is treated like a file that you can read and write to [12:52] so a soundcard device might live in /dev too and you can read from the microphone and write to the speakers [12:52] these devices are raw disks (sda) and partitions on them (sda1) [12:52] matematikaadit: I would say that anything over 1GB you can get away with no swap, but the more the merrier [12:53] Gryllida asked: how do I list all devices - the /dev/ ones? [12:53] ls /dev [12:53] Partitions are just bits of disks where raw data can be put. they don't have much organisation in them, you can't store files on them as such. For that you need a filesystem [12:54] The swap partition is a little different, it has no filesystem it is just raw disk that the kernel uses to temporarily store chunks of memory that it doesn't want right now. Swap to raw disk has less overhead than using a swap file inside a filesystem [12:54] you can create a filesystem in an empty partition using the mkfs command, something like [12:54] sudo mkfs -t ext4 /dev/sdax [12:54] Where x is the partition number you want to TOTALLY TRASH and install a filesystem on. Please don't break your computer with this command! [12:54] once you have a partition created, with a filesystem on it you can mount that in your own directory structure. For example you might mount it at the /home position if that partition was to contain all your user directories. [12:55] The /etc/fstab file stores information about all your filesystems and where they should be mounted as bootup. [12:55] you can also mount filesystems on the fly with the mount and unmount commands. [12:55] There are are 5 minutes remaining in the current session. [12:55] philinux asked: I've set mine up without extended. Just used 3 primary / /swap and /home. Any problem with this [12:56] so they are sda1, sda2 and sda3 right? [12:56] no great problem with that, just don't use sda4 for anything else, or you won't have anywhere to put the extended partitions if you want them [12:57] philinux asked: "I've set mine up without extended. Just used 3 primary / /swap and /home. Any problem with this" [12:57] Marceau asked: How do you mount a partition in a directory structure [12:57] philinux asked: correct [12:57] abhi_nav asked: is it recommended to install on whole single partition or have separate partitoin for /,/home,/boot,/tmp etc? [12:58] Marceau: sudo mkdir /mnt/myplace [12:58] Marceau: sudo mount /dev/sdax /mnt/myplace [12:58] so that will mount the filesystem that lives in /dev/sdax into the /mnt/myplace area of your directory structure [12:59] the place you are going to mount (the mountpoint) should exist, but does not have to be empty [12:59] although you won't get to the contents of it whilst something is mounted on top of it [13:00] abhi_nav: for a general use desktop PC I would go with the default "one hulking great big partition" (+swap) configuration === ChanServ changed the topic of #ubuntu-classroom to: Welcome to the Ubuntu Classroom - https://wiki.ubuntu.com/Classroom || Support in #ubuntu || Upcoming Schedule: http://is.gd/8rtIi || Questions in #ubuntu-classroom-chat || Event: Ubuntu User Days - Current Session: Using Ubuntu One - Instructor: shrini [13:00] Shrinivasan, is a open source lover, who lives in Chennai, India. He talks about open source philosophies in local colleges and schools. Currently he is giving technical support to subversion and TeamForge at CollabNet. He runs a weekly newsletter "FossNews" and a blog for Foss Jobs. [13:01] hello friends [13:01] good to to see you all here [13:02] "Ubuntu One" is a fantastic feature that comes with ubuntu for free [13:02] to make your files and folders follow you whereever you go [13:02] It started with ubuntu 9.10 [13:02] can be installed in ubuntu 9.04 too [13:03] ubuntu 10.04 makes it much better with added features [13:03] Gryllida asked: why is it called 'Ubuntu One'? Is it open source as well? [13:03] it is not open source still. [13:04] it is a personal cloud to store our files in the canonical's server [13:04] it is free only [13:04] not open [13:04] it is like the "DropBox" service [13:04] clients are open [13:05] and you can develop you own clients too. :-) [13:05] It has the following features [13:05] 1. storing your files and folders [13:05] 2. publish them online to easy access [13:05] 3. store and sync contacts [13:06] 4. store and sync Notes [13:06] 5. sync book marks [13:06] 6. Sync contact from mobile [13:07] 7. Buy Music from stores [13:07] abhi_nav asked: how much secure is storing our sensible files on ubuntu one? can we encrypt it? [13:07] storing files online is just like storing your emails and attachments with gmail. :-) [13:09] ubuntu one uses ssl encryption for the file transfers. so it is secured one. [13:09] http://one.ubuntu.com is the homepage [13:09] Canonical gives 2GB of free space to every ubuntu user in the world [13:09] If you need more space, you can buy it for 10$/minth [13:09] 10$/month [13:10] dnielsen asked: Is Phone sync support expected be expanded to the N900 (Maemo) or MeeGo any time in the future [13:12] yes [13:12] They are adding more phones and models [13:12] check them here. https://one.ubuntu.com/phones [13:12] Let us look at Installation [13:12] If you use ubuntu 10.04, it is already there. :-) [13:12] Look at the top right "Me Menu" [13:12] where you give about your status and details [13:13] Click on the "Ubuntu One" item [13:13] Thats all. [13:13] Firefox opens a page asking for you to create account or login [13:13] If you have a Launchpad account, use the same login [13:13] it is SSO enabled [13:14] If you dont have an account, you can create now [13:14] After login, you have to add your computer to the cloud. [13:15] It will show the "hostname" of your computer. [13:15] Click "Subscribe and Add this computer" [13:15] Viola! [13:15] You are added to the "Ubuntu One" Cloud [13:15] You will see the "Ubuntu One Preference" Window [13:16] click "connect" button [13:16] Thats all [13:16] you can get much information on https://one.ubuntu.com/support/installation/ [13:22] dnielsen asked: Is there a plan to offer a calendar and todo list syncing as well. It would be really useful especially for platforms like phones (thinking specifically of MeeGo here but android is also a candidate) [13:22] for now, there is no plan for calendar and todo list [13:22] we can add it later [13:22] The apis provide facilities to create our own application [13:23] to sync with ubuntu one. [13:23] you can get the development details in #ubuntuone [13:24] Gryllida asked: what is the location of ubuntu1 servers? how many are there? [13:24] The files are stored in amazon S3 servers in USA [13:25] Not did research on how many servers are there [13:26] Marceau asked: So what is the advantage of Ubuntu one over Gmail or Google docs? [13:26] You can not sync files with the size of 50MB in gmail [13:27] here, you can sync any files [13:27] your contacts, notes, bookmarks, music [13:27] The new feature is [13:27] you can sync any folder in your home [13:28] right click it, "Synchronize with ubuntu one" [13:28] this will sync all the content of the folder [13:28] to the cloud [13:28] Inside that folder, right click on any file [13:29] "Publish via ubuntu one" [13:31] it will sync the file and [13:31] give you a url [13:31] you can share the url with your friends to get that files quickly [13:31] dnielsen asked: Currently all my U1MS downloads in Banshee are stalled in "Transferring to Ubuntu One storage". So far your service isn't really that impressive, what improvements can we expect in the 10.10 timeframe [13:35] There may be a network issue [13:35] a lot of new features are getting added there [13:36] keep watching http://voices.canonical.com/ubuntuone/ [13:36] for new announces [13:36] You can sync your evolution contacts [13:36] https://wiki.ubuntu.com/UbuntuOne/Tutorials/Contacts [13:37] you can have ubuntu one address book and make it to sync with the cloud [13:37] you can sync the Tomboy notes [13:38] https://wiki.ubuntu.com/UbuntuOne/Tutorials/Notes [13:39] The Firefox bookmarks are sync'ed [13:39] so that you can have the bookmarks with you always [13:39] The new feature today is Music Store [13:40] you can buy music from 5 regional stores [13:41] The good news is there is no limit of 2GB if you buy music [13:41] your music will follow you as you move around computers [13:42]
