Leading up to that, Gutsy had a lovely wallpaper that looked to me like chocolate-coloured silk draped gracefully across the screen. One of my cousins said it looked to her like delicious chocolate mousse (and asked for a spoon) when I replaced her Mac's wallpaper with it.

And before that, Feisty and Edgy…well, I didn't like their default wallpapers, but they had the same alternate wallpaper which I'd forgotten about until now, and which I really liked at the time (and still do).

This one looks like melted dark chocolate to me. Anyone got a strawberry? Hmm, maybe it's good that the new wallpaper looks like a bruise. I wouldn't be wanting to eat my desktop…

Which release had your favourite wallpaper?

So I told them:

<maco> apt-get dist-upgrade differs from apt-get upgrade in that it will remove obsolete packages and add new dependencies, while apt-get upgrade will not. this is necessary when upgrading from one distro release to another, but it is not the *only* time it is necessary. thus, in aptitude, dist-upgrade has been renamed to full-upgrade
<maco> apt-get dist-upgrade will only change you from one release to another if you've modified /etc/apt/sources.list to point to a newer release, but this method of upgrading is not recommended

They also asked "and if i do want to upgrade the distribution (not that i do), how do i go about that?" to which I responded:

<maco> the recommended way to change distro releases is sudo do-release-upgrade

They said it was the best explanation in the shortest amount of text, so I'm posting it here, hoping it'll make it easier for people to find. By the way, man apt-get does explain all this…just in slightly more technical terms.

Subject: I had no idea that hot girls liked linux
Body: Are there more of you? I mean how does that happen? How does a good looking female put off their social life to the point where they can actually use ubuntu without ripping their eyes out?

Seriously, I don't want to hear it. Just think about it for one minute. What does appearance have to do with technical ability? Why do all the good looking men involved in K/X/Ubuntu put time into their favourite distro that could otherwise be spent on their social life? My answer's not going to be any different than theirs! And for that matter, why should it be social life or Ubuntu? Consider that many of the developers are friends with each other.

Also, isn't that being a little mean to Ubuntu? I mean, yeah, it's not as awesome as Kubuntu, but.…still… (joking!)

And yes, that's an actual email I received today. Ugh. Including his name and email address here is /very/ tempting, but it'd also be unethical, so I won't.

The purpose of a link is to allow you to have two (or more) paths to access the same data without having the data exist on disk multiple times, thus giving convenience without sacrificing disk space. So why are there two kinds of links and how do they work?

Symlinks (ln -s REALPATH LINK) work like this:

LINK --> REALPATH --> DATA

While hard links (ln PATH1 PATH2) work like this:

PATH1 --> DATA <-- PATH2

See what's happening here? In the symlink case, your link points to another path, which points to the data. In the hard link case, two paths point to the same data directly. I think I could get a lesson on pointers in C out of this ASCII art if I wanted to. If you want a bit more background, your hard disk's filesystem contains a table of inode numbers, which is just like the Index at the back of a book. Symlinks are when you get "(see also: rubber ducky)" and hard links are when you get "Rubber ducky: 5" and "Sesame Street: 5" both showing up in the Index. Since we can have multiple filesystems mounted on one machine (for example my /home is on a separate partition), it is important to note that while a symlink can point to something located on another disk (or in a book "Further reading: Little Red Riding Hood"), a hard link only knows about data on its own filesystem (ie same partition). So, if you want to link from your hard disk to a flash drive, you need to use a symlink. This makes sense since your hard disk can't know if your flash drive rearranges things while it's plugged into another computer.

How do these show up in ls? Hard links look like normal files. For symlinks ls -l --color will show LINK -&gt REALPATH. If REALPATH is deleted, this will be highlighted as red text on a black background.

Speaking of deletion, how does that work? Well, if you remove LINK, REALPATH and DATA will still exist. If you remove REALPATH, DATA goes away too and LINK just points at nothing (though if you add REALPATH back, LINK will start working again, as it only goes by filename). As for hard links, DATA goes away once no more inode numbers point to it. As mentioned before, hard links point directly to the data, so this means removing all links and the original filename. So if I remove the original filename (PATH1), PATH2 will still point to DATA.

I hope that's a straightforward enough explanation of how it works.

1. How should I download?
   • Torrents, to keep the strain off the servers. There are IPv6 torrent files available as well, as a test so Canonical can see how many Ubuntu users are on IPv6 and thus how much support to give it. They don't list KTorrent as one of the clients that can do the IPv6 torrents, but I'm using it right now.
   • Or if you have a Beta or RC .iso sitting around zsync to the final
2. I have a netbook. What are my options?
   • Ubuntu Netbook Remix is still around, but it's now joined by Kubuntu Netbook Edition
3. How's audio?
   • Well, it's working fine for me, but Daniel has a "caveats" blog post (updated link). There is now a linux-backports-modules-alsa-karmic-generic package so you can get ALSA updates
4. Where'd Add/Remove go?
   • It has been replaced by the new Ubuntu Software Center
5. Does Ubuntu Software Center sell proprietary software? I heard it did.
   • Not yet. There are plans in about a year to allow those commercial developers who are willing to support Linux to sell apps through it.
6. Can I use Ubuntu One with Kubuntu?
   • Yes, just install the ubuntu-one-client-gnome package.
7. Why Empathy? I like Pidgin!
   • You're welcome to keep using Pidgin, but here are a few things Empathy has going for it:
     • It's the GNOME default
     • It can do audio/video chat
     • The Telepathy framework lets it integrate better into the rest of the desktop
     • As Jono mentioned you can do desktop sharing through it
8. What happened to GDM theming?
   • The new GDM uses the GTK theme for the gdm user. To change it, you'll need to run gksudo -u gdm gnome-appearance-properties and select a new theme
9. Wasn't Gwibber supposed to be included?
   • Gwibber 2.0 was not ready in time. It is available in Universe.
10. New theme yet?
    • Yes! Softer icons, chocolate highlights, and orange wallpaper
11. Can Amarok play CDs yet?
    • Yes
12. Do Intel graphics not-suck this time?
    • Yes, they're very nice actually! Thanks to KMS, Intel graphics users can expect instantaneous resume from suspend!
13. How's Kubuntu's network manager?
    • It works this time
14. I upgraded from Jaunty and now have no sound. What do I do?
    • Run uname -r. Does it say "2.6.31-14-generic"? If it still says 2.6.28-16-generic, you're not running Karmic's kernel. Some people are having trouble with GRUB not showing new kernels. Try running sudo update-grub and then rebooting.

Additionally, I wrote an overview of Ubuntu and Kubuntu for another blog, if you'd like to check that out.

PS: Let me know in the comments if there's anything you think I should add!

It does make sense, right? I mean, you just can't hang around the guy without getting at least 1 hug (more likely: a half dozen) and a huge grin.

Yeah yeah, off topic for this blog (again), but Jorge Castro said I had to blog the picture of his Care Bear coworker.

* To those who don't follow Ubuntu development and thus going "uh…who's Daniel Holbach?" He's one of Ubuntu's Community Council members, and a developer, and…ya know the list's too long.

Maybe it was threatening or phishing or spam. How do you gather evidence of what servers passed it to you to give to the authorities? You need the full headers. They contain all the routing information. Keep in mind, though, that it is possible the sender was making use of an open relay instead of their own mailserver.

   • KMail: View -> Headers -> All Headers
   • Evolution: View -> Message Source (or Ctrl+U)
   • Thunderbird: View -> Headers -> All
   • GMail: Hit the down arrow next to "Reply" on the message, then choose "Show Original"

   Now just copy and paste this into a file and hand over to whomever is dealing with the sender.

   With all the discussion of sexism in FOSS this year, a certain individual calling himself MikeeUSA is back. I realize many people are not aware of this individual. He is notorious in certain circles for very good reasons. 2005 is the earliest record I know of him harassing women involved with Debian and LinuxChix. And last year, he sent death threats to many women involved in Debian development.

   He's back, pasting the same comment to many blogs repeatedly. Not everyone has removed the disgusting comment, so I'm sure you can find it if you want. But, here's a summary of his beliefs:

   1. Hans Reiser was justified in murdering his ex-wife since she divorced him; the only down-side is that he can't code while in prison
   2. Men have the right to rape women, and rape laws are stealing that right
   3. Pretty much all laws that require treating women as well as you treat your dog require stealing men's rights
   4. etc.

   I hope you can see where this is going. Obviously nowhere good.

   My advice? Do not engage; he is not receptive. Delete with impunity. Note also that he uses Tor, so an IP address block on your blog comments won't work; email address block should work for a while. Also, warn the others, and tell women you know involved in Free Software that if this guy comes after them in any way, they NEED to speak up.

   
   
   

   Yes, I know, this blog has been very offtopic for a while now. I'm sorry. The software I'm most impressed by at the moment isn't packaged in Ubuntu though! I know, I need to go file a FFe to get it synced from Debian so I can write about it.

Others have already written about it on their blogs, so I'll save some of the repetition. Three of the guys from Southeast LinuxFest approached me about talking there next year. ZaReason had a table showing off their Terra A20 netbook and a couple machines that are not yet available for sale (yay! previews!). Earl asked me about an audio problem they were having with one of the preview machines, so I got out a Karmic UNR stick and booted from it. Turns out it works fine in Karmic. Go ALSA people!

   I've got photos from the wedding, pre-party, event, and after-party on my Flickr. There are three videos of Greg Grossmeier dancing like Carlton from Fresh Prince. I've also got a video of a MacBook failing to properly detect a projector when we (the speakers) were testing our laptops with the projectors on Friday. For the record, xrandr --output VGA1 --same-as LVDS1 --mode 1024x768 ; xrandr --output LVDS1 --mode 1024x768 was all I needed (note: too lazy to learn to use the GUI).

I'm currently at the "checkpoint" on the trip to Columbus. By that I mean, a coworker and I are crashing at our bosses' house. We're leaving in about 4 hours.

   I'm working on my slides. My talk is called "Sysadmins' Rosetta Stone" and is about all those little things that trip you up when you switch from Debian or Ubuntu to Red Hat or Fedora…or vice-versa. It's aimed at system administrators, though, so fair warning. I just took a second look at the schedule, and it appears I am scheduled to speak at the same time as my coworker and boss, Scott Courtney and David Boyes. They're talking about IBM VM. I wonder if the opening line will be "back in my day…" ;-)

   I'm thinking I'll also go to Cat Allman's "Getting Started in Free and Open Source" to get ideas for sharing with beginners and Dru Lavigne's "BSD for Linux Users," since I have a friend that's always trying to switch me to FreeBSD and every time I use OSX I have to relearn the flags for various commands (ex: ls --color is ls -G on BSD…I think). Elizabeth Garbee is an excellent speaker, so I think I'll attend her "How to Use Open Source to Pay for a College Education." After her…well, I'm not so sure. Maybe Mike Badger's "Programming for the Young and Young at Heart" to get tips on teaching kids, or maybe Tom Callaway's "Legalities of FOSS from a Hacker's Perspective." After that, Jorge is doing "Building a Community Around Your Project." For the last time slot with choices, I'm still unsure about Patrick Wagstrom's "Be a Wonk! Open Source, Government Policy, and You" or Catherine Devlin's "reStructured Text: Plain Text Gets Superpowers."

In 2006, Kevin (the LoCo leader) says the table was well off the beaten path. Very few visitors. 2007 was my first year participating. That year we got a better spot, just around the corner from the lawn area where the main stage is. Anybody wanting to reach the main stage from that side of the building had to go past us. We got about 120-150 visitors. In 2008, we had the same spot, and this time the OLPC Learning Club folks got a table to our right and the hackerspace, HacDC was to our left. Again, we got about 150 visitors.

   This year, though? We were on the edge of the lawn. Hard to get from the food to the main stage without passing us. Well, we lost track of pressing the button on the counter for large swaths of time because we were so swamped, but of the times that we remembered…362 visitors. Yeah, WOW!

   

   We find that having OLPC XO laptops seems to attract folks. "Is that the laptop from the news?" and then we get to explain Free Software and oh hey look, we have CDs for another Linux distro here called Ubuntu… Mel Chua was there in the morning. She used to work on OLPC, and I heard the reason she had to leave early was to fly down to NC to Red Hat headquarters for new employee orientation. Woot for Mel! Mike Lee came in the afternoon to take her place as Resident OLPC Expert. He runs the OLPC Learning Club.

   

   I'd say about ½ the people who came to the table last year said they either already used it or someone in their family used it or they remembered us from the year before. That's about 75 people. This year, probably 100 said that sort of thing, maybe 100 more said they'd heard of Linux in general but not Ubuntu and isn't it hard to use? That means we had at least 160 people who'd never heard of this before but know now and another 100 who got some more information. Yay! Hundreds more than last year! This is what I like about being at a folk festival instead of at a tech conference. We're not preaching to the choir, to the techies who already know all about Linux and have made up their minds about it already. We're talking to the "human beings" mentioned in Ubuntu's tagline. Several people also asked for lists of netbooks that come with Ubuntu pre-installed.

   

   I think we went through 3 boxes of Ubuntu CDs. Unfortunately, we only got to give out 5 Kubuntu CDs because that was all Kevin happened to have lying around. It seems our Jaunty ShipIt pack didn't include any, and he didn't open up all of the boxes in advance to count.

   

   Taking care of the booth this year, aside from Mel and Mike on OLPC duty, were Kevin Cole (runs the DC LoCo), Other Chuck (I don't know his last name, but he's known as "Other Chuck" since Chuck Frain runs the Maryland LoCo and that's not him), Daniel Chen (y'all know him by now, right?), and me (oh come on). And as in years past, Barry Warsaw (Canonical, maintains Mailman & Python) stopped by the table. He has his son trained to give double-thumbs-down to Windows, hehe!

   

   For photos of all the fun, check out my Takoma Park Folk Festival 2009 album on Flickr. It, er, appears I need to learn about a better color setting for my camera in really bright sunlight because everything's blue-ish, except for people's brightly-colored shirts. Excuse: it's a week old, I haven't gotten used to it yet! Though I did find the setting for brightly-colored flowers. Lots of photos that'd make nice wallpapers in my Flickr now.

   Kate is a text editor for KDE. The name Kate is an acronym for KDE Advanced Text Editor.Kate has been part of the KDE since release 2.2 in 2001.Because of the KParts technology, it is possible to embed Kate as an editing component in other KDE applications. The integrated development environment KDevelop, the web development environment Quanta Plus, and the LaTeX front-end Kile are three of the major KDE applications making use of Kate as an editing component.
   
   Kate is so far the best IMHO. Most essential features that a modern editor should provide such as session management, syntax highlighting, word completion, indentation, and scripting/plug-in system are all decent here except for code folding.
   
   The XMLs are located at /usr/share/apps/katepart/syntax/
   
   Find your targeted language style XML, and find at the end of the file the element general,
   add a child element to it:
   
   
   
   That's it.

   Ubuntu has a root password; they just don't tell the user what it is.

   Rubbish. Some versions claim it is a randomly generated one. Rubbish. There is no root password, and this statement mustn't be confused with "the password is carriage return" (a usage RMS tried to popularize at MIT). Take a look at /etc/shadow, if you will (sudo less /etc/shadow). On a default install, the first few lines will look something like this:

   root:*:14438:0:99999:7:::
   daemon:*:14438:0:99999:7:::
   bin:*:14438:0:99999:7:::
   sys:*:14438:0:99999:7:::
   sync:*:14438:0:99999:7:::

   Contrast this with the line containing your user's name.

   test:$6$.XQFA5P3$JYH9CpZS00DUAPDXcxc5qzP2vaNLrGj2TB5dlLj6rEVCOMpTt5XmFH7eL2TiDtXGApTknWhO6phpGyuac3DCU.:14470:0:99999:7:::

   What is different? The second field (the part after the first ":") is a "*" for those system users and a long jumble of numbers and letters for the human users. The "*" means that the user cannot login using a password. The long jumble of numbers and letters? That is a hash of the user's password. In this test user's case, that is a hash of the string "password". If you're interested in the other fields, see man 5 shadow. This password has been encrypted with SHA-512, as evidenced by the $6$ at the start of the hash. See man crypt for a list of other possible prefixes. Note that $1$ means MD5, a hash which has been rather thoroughly broken. Since 8.10, SHA-256 and SHA-512 are available and will be used if you reset your password. If you've still got an MD5 hash in there, it's likely a good idea to do so, if only because it means you haven't changed your password recently enough.

   This rumour usually comes up in the context of someone pointing out that if you are a remote attacker, you can guess that root has all the power and so all that is needed is to brute force root's password. In Ubuntu's default setup, this won't work because there is no password that would succeed, regardless how long you spent generating new passwords to try. Instead, the attacker would need to guess the correct combination of user-who-has-sudo-access and password—something exponentially harder. Well-meaning but misguided folks, attempting to protect us Ubuntu users from a false sense of security, then warn us that no, we're wrong, Ubuntu does have a root password. Well, the evidence is in /etc/shadow for all to see. Ubuntu has a locked root account, just the same as if one were to run sudo passwd -l (see man passwd).

   This tutorial will explain Howto install and Enable Broadcom Wireless in Ubuntu 9.04
   
   Procedure to follow
   
   1. Connect your computer to the intenet using the wired LAN connection. I.E. Plug in you network cable to the computer in question to connect to the intenet.
   
   2. Go to System > Administration > Hardware Drivers. Enter your password.
   
   3. If you see “Broadcom…. wireless driver”, select it and click activate near the bottom of the window. It should be right above the close button. It should activate the driver, and the circle next to the “Broadcom… wireless driver” should be green.
   
   4. Disconnect the wire connect from your computer.
   
   5. Right click on the wireless strength bars at the top left of your screen. If you see a wireless network click on that, enter the passkey if necessary, and that is it.
   
   BUT, if you don’t see a wireless network available and you know that there is one, we have a few more steps to take.
   
   The Hard Way (use this if the above procedure didn't work for you):
   
   1. Do the steps in the Restricted Driver How To and The Easy Way.
   
   2. We need to install B43-fwcutter. To do this we go to System > Administration > Synaptic Package Manager. Enter your password.
   
   3. Go to Edit > Search, and search for fwcutter. You should see b43-fwcutter in the Package window.
   
   4. Left click the box right before the name. If it is grey, click mark for installation. If it is green with a star, click mark for upgrade. If it is green, do not click anything.
   
   5. Click Apply at the top of the window if you clicked mark for installation/upgrade. Then follow the prompts to install/upgrade. Close out of the Synaptic Package Manager.
   
   6. Go back to System > Administration > Hardware Drivers. Enter your password if prompted. You should now see the “Broadcom… wireless driver”. Activate it.
   
   7. Right click the wireless signal strength icon to see if you see a wireless network. If you do, congratulations you are finished. If not, lets move on to the terminal.
   
   8. Open the terminal by going Applications > Accessories > Terminal.
   
   9. Type in: sudo modprobe -r b43 b44 ssb wl ,and hit enter.
   
   10. Type in: sudo modprobe ieee80211_crypt_tkip ,and hit enter.
   
   11. Type in: sudo modprobe wl ,and hit enter.
   
   12. Type in: sudo modprobe b44 ,and hit enter.
   
   13. Type in: sudo /etc/init.d/networking restart, and hit enter.
   
   14. Now right click the wireless signal strength icon and you should see a wireless network at this point. Click on the network shown and connect.
   
   This fix goes away when you restart because the wireless card deactivates itself. You do not need to re-install the driver again, but you do need to at some code to rc.local file so that it reactivates on start up.
   
   Code to Add to rc.local file:
   
   1. Go to terminal if you don’t still have it up and running from activating your wireless card.
   
   2. Type in: gksudo gedit/etc/rc.local or sudo gedit/etc/rc.local
   
   3. That should open up a text editor with the file rc.local opened. You should see some blue text with #’s in front of it and an exit 0. You are going to add the following code to the file right before the “exit 0″ at the end.
   
   #Activate Broadcom Wireless Card
   
   modprobe -r b43 b44 ssb wl
   modprobe ieee80211_crypt_tkip
   modprobe wl
   modprobe b44
   /etc/init.d/networking restart
   
   This file runs at start-up and will run the commands for you right after Ubuntu has finished loading.
   
   4. Click save and exit out of the program.
   
   5. Type exit in the terminal and hit enter. This will exit out of the terminal.
   
   Notes:
   
   Sometimes it takes a few seconds to a minute for the rc.local file to run the commands, be patient.
   
   If the Network Manager asks you for a passphrase after you entered the network’s passkey, make it easy on yourself, put the same password for that as your user login.
