First up the minor problem, after rebooting into the new hotness of Ubuntu 9.04, I was greeted with a pop-up windo telling me “There was an error while performing indexing : Index corrupted.” The pop-up gave 3 options: “Ok”, “Cancel” or “Reindex all contents”. I tried all 3 but the pop-up kept coming back even after multiple reboots. The only thing I could initiall figure out to do was to kill the tracker
ps -ef | grep tracker
kill -9 XXXX XXXX XXXX

Yes, I know that’s probably a horrible idea but I rarely use the tracker’s search on my home PC so pbbbhhhhttt! A quick Google search later, I found a bug report on LaunchPad about it under which I found these instructions:
sudo aptitude install tracker-utils
tracker-processes -r

I apparently already had the tracker-utils  installed, so the first didn’t do anything for me. The second command above however shutdown the tracker and removed the indexes, so the tracker was able to recreate them cleanly. Since running those commands, the pop-up hasn’t come back.

Now on to the fun with the major problem. This was a case of network failure, specifically wireless network failure. While this is a desktop PC, I live in an old house without network cabling and my PC sits too far away from the ideal location for the router to run a cable. So I have a D-Link PCI wireless NIC in my desktop.  The NIC is based on the Atheros AR5413 chipset, Network performance has never been as good as a wired connection but it had been acceptable until this upgrade to 9.04 when the wireless stopped working.

I had been using ndiswrapper to load the windows driver for the card but that suddenly stopped working. I could see all the wireless networks in my neighborhood, but couldn’t connect to any of them (either networks secured with WPA or wide open ones). I started doing some research into the problem using other computers with working internet connections. I found that my router was getting blacklisted while my desktop was trying to connect and then it would timeout without ever making a network connection.

Also while researching the problem, I found out that there was now a new, open source driver which should be working with my wireless NIC (ath5k).  So I removed ndiswrapper, and tried out this new driver. Alas it wans’t particularly stable, dropping connection ever couple of minutes. However since my wireless NIC uses an Atheros based chipset, I had another option. I installed the madwifi driver via jockey-gtk (Ubuntu’s tool for installing restricted modules/drivers).  For whatever reason, activating the driver via jockey-gtk didn’t actually get it up and running. To test it, I used:

sudo modprobe ath_pci

To actually get the driver to load on every boot, I edited my /etc/modules file to include ath_pci.

The madwifi driver doesn’t appear to make as strong a connection as the ath5k did; the gnome network manager applet shows the connection under madwifi usually has ~45–55% signal strength (under ath5k & ndiswrapper I could get as high as 70%). However I’ve yet to lose a connection to my network while using the madwifi wrapper whereas ath5k would drop connection every couple of minutes and ndiswrapper would usually drop the connection at least once an hour (back on Ubuntu 8.10 where it actually worked for me). Also the madwifi driver allows me to connect to my network on boot-up; unlike ndiswrapper which always took some time to connect after I was booted up and signed in. So overall, I’m pleased with my new networking setup but would have been more pleased if the changes I made could have been done automagically by the upgrade process or if the upgrade process at least warned me that it might break my networking setup.

First off if you are having problems with a certain contest, then plugging the secret letters into the Internet Anagram Server could be very helpful.

I like RPGs and play in a couple now & then.  I have also run the occasional session or two, but lately I got this itch.  The itch to play in a campaign world of my own devising which means I’ll need to run more than a single session or two. In trying to prepare myself for that, I’ve been following some new blogs and today read the logical article I’ve ever seen on the subject of war & international relationals.

This week while staying home sick¹, I finally got around to upgrading my work laptop from Ubuntu 8.04 to 8.10. I had been holding off mostly because it is my work machine and I had the idea I should keep it on Ubuntu’s LTS releases. Then I realized while I was keeping the system on a theoretically more stable version, I kept adding 3rd party packages/repositories to update specific programs I wanted (which contradicts the point of sticking with a LTS release). So I did the upgrade and was pleasantly surprised at how smooth the upgrade went. However I did run into one minor and one major problem after the upgrade.

• Minor problem: My dual monitor configuration got screwed up. Most likely because I did the upgrade at home (where I don’t have a 2nd monitor for the laptop).
• Major problem: All my SSH keys stopped working. I ended up recreating them and getting them pushed back out to all the servers I need to access using keys. Still that was disconcerting, especially since nothing about the keys (client/server) had changed. Even our network admin at work was confused by that one.

On the positive side, Adobe Flash Player 10.x is available for Ubuntu 8.10, so now I can watch Comedy Central’s clips of the Daily Show again (under Flash 9.x, they always crashed Firefox). Additionally there are prebuilt packages for Gnome-Do 0.8.x for Ubuntu 8.10, which like Mr. Pibb + Red Vines is crazy delicious! Specifically, Gnome-Do with the Docky theme. I believe the idea behind the Docky theme was to mimic some functionality of OS X’s dock, but could be mistaken (don’t own a Mac). The performance is bit slow on my older desktop², but it works great on the work laptop.

¹ Nausea + dizziness + complete lack of energy. Fortunately I’m mostly over it now, though still working to get my energy levels back up.
² Based on an AMD 1800+ CPU.

The side effect of Nautilus working so poorly was I had time to do a little googling.  I’ve heard good things about the Hulu website for watching TV shows I’ve missed.  Thing i I hate sitting at my computer for long periods of time when I’ve got a comfy couch¹ and a much larger TV than computer monitor. So as I said, I started googling and looking for a XBMC/Hulu plugin and I did find one in the XBMC Forums.

Unfortunately the 0.2 release mentioned in the first post of that thread didn’t work so well for me and there were 38 pages in the thread.  I did some more searching and found an article over at LifeHacker.  The article seems to be talking about the same plugin but links to a newer release of it.  I kept looking to see if there were anything else out there and found what appears to be the main site for the plugin, xbmc-hulu.  That last site doesn’t provide a simple download, but you can use subversion to checkout the lastest copy of their plugin.

And that latest version is pure gold, which is to say I’ve not run into a single problem watching any videos via the plugin.  Now I can sit back on the couch and watch Colbert Report, The Daily Show and all sorts of other good stuff that I don’t get with my cable TV package.  If my sinuses clear up and this cold goes away, I could be really happy.

UPDATE: I appear to be getting quite a bit of traffic (for me anyway) on this post, so thanks for stopping by! Also I’ve finally read through the entire 40 pages (at the time of this writing) in the XBMC Forums thread about this plugin.  From reading that thread, there appears to be a lot of confusion on where/how to get the plugin to work.  So for the record, I’m running xbmc-hulu 1.0 (SVN copied checked out on 26 January 2009) on top of T3CH’s 2009-01-25 build of XBMC (rev17349) on an original XBox (softmodded using Mech Assault via ProductWiki’s instructions).

UPDATE: Per the XBMC-Hulu plugin release thread, there is no currently working version of the plugin.

¹ Someday I will have a comfy chair!

I used to love FPS games; but as I’ve gotten older, I’ve lost most of my taste for them. Probably because my reaction time is down and I’ve had less spare cash for PC upgrades to be able to run modern FPS games.

I’m also a bit cheap so I don’t tend to go for the latest console systems. Though I did end up buying a Wii last year and have been enjoying it greatly. Specially the Lego games (Lego Star Wars, Lego Indian Jones, etc..).

I’ve also played Rock Band/Guitar Hero at friends’ places and enjoyed those as well but haven’t picked up it yet (cheap + pricey controllers = delay in buying).

Good

• The actual upgrade process completed without errors.
• The computer was successfully upgraded from 8.04 to 8.10 without any manual intervention on my part.
• Desktop effects (aka compiz) are very fun.  I’d tried them in the past with less than stellar results (too buggy) but they seem much more stable now.
• The extra buttons on my trackball finally work righ with Firefox under Ubuntu (back/forward).

Bad

• The upgrader removed and did not reinstall the restricted kernel modules.
  • For my less technical readers, basically the upgrade broke both my wireless connection and 3D acceleration.  I could live without the 3D, but this computer relies on wireless to connect to my home network.  Fixing that took a couple of hours of digging around in the log files and using another computer to get the files I needed.  Major headache.
  • I understand why the modules were removed and not installed after the upgrade, but I wish the upgrader had been smart enough to realize I needed them and would have at least downloaded them to be available after I rebooted to complete the install.
• KDE 4.x is the new default desktop environment for Kubuntu.  KDE 4.x does not play nicely with Nvidia graphics cards.  Like the one in my computer.  Meaning the lag between clicking on a the K menu and the menu popping up was about 2 minutes.  *ugh*  I could disable the Nvidia drivers to get normal performance back but then I’d lose my 3D acceleration.  *sigh*  So I’ve switched over to using Gnome, which will probably make at least one person I know very smug.
• The network shared drives I had setup to be automatically mounted on every boot are no longer mounting.  Gnome has an easy way to connect to those shares, but I really don’t want to have to mount them manually every time.

Update: For those of you stopping by looking for instructions on how to do this upgrade, you can fine the complete instructions (with screenshots!) over at Ubuntu’s Community Documentation page for IntrepidUpgrades/Kubuntu.

I’d also like to take a momemt to thank AWelkin & Bryon for the gifts they brought back from Japan for me. I’ve now decorated my cubicle with 3 Tachikoma gashapon. *yeah!* Also a quick thanks should go out to my buddy/ex-coworker Eric, he mentioned more than once I just needed the right motivation to get into programming¹.  Well I recently had some slow time at work and wanted a way to parse some badly formatted data; so I wrote a Python script and while doing so certain things that have never clicked in my head about programming started falling into place.  I’ve since started working on another Python script for a different project at the office, so perhaps there’s some hope for my coding-fu yet.

¹ I do a lot of computer stuff, but have never been much of a programmer.  Usually I just learn enough to hack somebody else’s stuff together to do what I want in rather ugly hacks.

When I got up this morning, it was still running but was hung up on a question I needed to answer. I clicked through the question and a few more before heading off to work. When I got home, again the upgrade was hung up on a question. I worked my way through answering all the questions and let the upgrader do its job. Unfortunately the upgrader eventually failed on these packages: gnome-applets-data, gnome-applets, ubuntu-desktop and update-manager. I clicked through the errors and then the upgrader said:

Could not install the upgrades
The upgrade aborts now. Your system could be in an unusable state. A recovery will run now (dpkg –configure –a).

I clicked ok to the error, something flashed up and then the upgrader died/vanished/went away. I tried running:

• sudo aptitude update but it sat there for far too long for my sleep deprived and impatient self.
• sudo aptitude upgrade, only it said there wasn’t anything to upgrade.
• sudo aptitude autoclean, *shrug* it's part of my standard script for updating my systems.
• sudo aptitude dist-upgrade, only it said there wasn’t anything to upgrade.
• sudo dpkg --configure -a, it said there were unconfigured packages but it couldn’t fix them automagically. It mostly complained about gnome-applets-data.

I ended up running sudo aptitude install gnome-applets-data gnome-applets ubuntu-desktop update-manager and that fixed up those errors no problem. For giggles of insanity I tried running sudo aptitude -s -f install to see what else might be left to update³. It found another 111 packages it wanted to remove but some of them I want to keep, so I’ll have to look into that more closely. Most likely all these errors were caused by my own foolishness, as at one point I was testing some stuff out on the machine and enabled some 3rd party repositories to install unsupported apps. *blech* I don’t think I’ll be doing that again. I was able to reboot the machine and connect to it via SSH and SMB, but HTTP seems to be broken at the moment. *bugger* Apache is one of the packages sudo aptitude -s -f install wanted to remove. I guess looking into that just got bumped up my priority list.

² Never fear, Fritz (my desktop PC) is next on my list of machines to upgrade.
³ More accurately, I found some instructions when upgrading my desktop from Dapper to Gusty that recommended doing that to ensure all apps got updated.

I looked at the code Rob used and with a little help from the Practical PHP I hacked together my own function based on Rob’s. By default print_reader2 works the exactly the same as print_reader¹ but by feeding it an additional parameter, you get your choice of what to use to display as reader’s name:

• 0: Prints out the user_login aka the username you use to log into WordPress.
• 1: Prints user_nicename, appears to simply be an all lower case version of the user’s nickname².
• 2: Prints display_name, from the “Display name publicly as” field in your WordPress profile.
• 3: Prints first_name, from the “First name” field in your WordPress profile.
• 4: Prints nickname, from the “Nickname” field in your WordPress profile.

function print_reader2( $echo=true, $reader_id = 0, $display = 0 ) {
	global $userdata;

	$username='';

	switch($display) {
		case "1": if (!$reader_id) { get_currentuserinfo(); $username = $userdata->user_nicename; } else { $user_info = get_userdata($reader_id); $username = $user_info->user_nicename; }; break;
		case "2": if (!$reader_id) { get_currentuserinfo(); $username = $userdata->display_name; } else { $user_info = get_userdata($reader_id); $username = $user_info->display_name; }; break;
		case "3": if (!$reader_id) { get_currentuserinfo(); $username = $userdata->first_name; } else { $user_info = get_userdata($reader_id); $username = $user_info->first_name; }; break;
		case "4": if (!$reader_id) { get_currentuserinfo(); $username = $userdata->nickname; } else { $user_info = get_userdata($reader_id); $username = $user_info->nickname; }; break;
		default: if (!$reader_id) { get_currentuserinfo(); $username = $userdata->user_login; } else { $user_info = get_userdata($reader_id); $username = $user_info->user_login;};
   }
	if ($echo)
		echo $username;
	return $username;
}

Side note: WordPress 2.5.1 got released today and it includes a security fix, be sure to update your blogs!

¹ At least, I think it does. I’m not a programmer and I only know enough PHP to be dangerous to myself.
² The WordPress Codex does not appear to define what this field is used for or why it exists, so that’s just my guess.
