IT’S ALIVE!

The GoogleBox lives!


Yes, after 4 days of downtime, my illustrious yellow 1U server has been revived from the dead. After it died, I asked the colo provider to power cycle it, and they said it didn’t come back up. I asked them to yank the box, and I picked it up and brought it home. Expecting a power problem, I first tried yanking all the hard drives and memory, but even then didn’t get any beeps or other activity. So then, I tried yanking one of the CPUs. I must have gotten lucky, because removing the #2 CPU got me a couple of POST beeps, and when I put back the memory and the hard drives, it booted just fine.

I’ve had this box since January 2007, and the CPUs are dated from 2001, so I guess it’s time to replace it. I ordered a slightly newer box off eBay that has twice as much memory and 4 SATA drive bays. With two 1Tb drives, it will have much more disk space, but more importantly the empty drive bays mean that if I need to expand, I can add newer bigger drives when they become available. I’m considering using software RAID to mirror the two drives, because even 1Tb is bigger than what I have now and I’m not hurting for space. And with lvm, I can plonk in two new 2Tb drives when the time comes, migrate the volume groups to the new drives, and yank the old ones. All the remains now is to decide whether to build a new OS and get everything working on it, or just restore from a backup and continue the upgrade path.

While I had the box home for a few days, I took the opportunity to do a long-delayed upgrade from Debian “etch” to Debian “lenny”. I didn’t want to tackle that remotely because there was a significant chance (and it happened several times) that I was going to get it into the situation where I needed to intervene at the Grub stage, and I couldn’t do that remotely (because the cheap colo facilities don’t give you remote boot consoles like the expensive ones do.) The biggest hassle of this upgrade was that I had to do some messing around to get a console to appear, changing the boot options on the box itself, and also the getty lines in inittab of each of the guest “domU”s. The second biggest hassle was that I had to install “udev” on all the guests so that ssh could work. Also while they were home I took the opportunity to make a backup of the whole thing, including the guests that don’t belong to me. Normally I just back up my own. That should make setting up a new box a lot easier.

I got all the fixing and upgrading and backing up done early this morning. I brought my box over to the colo company office at 10:15. And waited. And waited. And waited. I had a “ping -a” running so I’d know as soon as it came back. And I waited some more. The business office is the other side of town from the colo facility, so I figured there would be some delay. The company that used to own those racks would let me go out to the facility with them, but these guys bought the business from that company and they’re anal about security and won’t let me go. Well, it turns out that their scheduled visit to the colo facility was at 10pm – nobody told me that, of course, until after I’d started panicing that they’d all gone home for the weekend without racking my box. But here it is – they racked the box, phoned me to say it was powering up, and now I’m connected again. Hallelujah!

Chrome – still not great

Update: A few hours after I wrote that, I decided to quit and restart Chrome to free up some memory, and now none of the extensions I installed are showing up.

A few weeks ago, I wrote about my experiences with Google Chrome on the Mac. At the time, Chrome on the Mac was lagging quite far behind the Windows version. Supposedly now it’s all caught up, and so I’m going to revisit my previous complaints:

  • It frequently lost the text cursor in text input fields, especially on GMail.
    • Still happens.
  • It seemed much slower and more likely to corrupt the display compared to Safari in Google Wave.
    • I haven’t been using Wave, so no comment.
  • It had a bad habit of undocking a tab on the slightest provocation.
    • Still happens.
  • The fact that the tabs take up space in the window frame means that you’d frequently undock a tab when you were trying to move the whole window.
    • Still happens. There is a tiny bit of real-estate near the “+” to open a new tab that is still available, but it’s a pain to grab.
  • It doesn’t have a “Reload all tabs” option. Supposedly there is an extension to that, but in order to use extensions I’d have to upgrade to the latest development build. That’s more work than I’m willing to do when it has all these other problems.
    • I found an extension that will reload individual tabs on a schedule rather than the whole window on demand. That’s actually nicer than having to reload everything manually. It’s not bad, except when your computer goes to sleep you have to restart it by reloading all the tabs individually. Plus when it reloads on a tab that is on a different Space than the one you’re on, it will switch back to that Space, but that’s a Spaces problem not a Chrome problem.
  • It doesn’t recognize or tell you about RSS feeds. In Safari or Firefox, any page that has an RSS feed displays an icon, and if you click it, the OS opens the feed in the currently configured RSS reader. The functionality is so ingrained in browsers that many pages don’t seem to have any other indication that they have RSS feeds. Once again, I’m told that Chrome has a plug in for that. Once again, too much trouble.
    • The only RSS plug ins I could find will add the RSS feed to a web based RSS reader like Google Reader. There is no support I can find anywhere for the OS-defined RSS reader. So I’m experimentally putting NetNewsWireLite out pasture in favour of Google Reader. Not bad, but not great.

So over-all, it’s got a few user interface annoyances, but the really big sticking points have been taken care of by plugins. And I was happy. Until today. And that’s when I discovered that Google Chrome is utterly useless for a web developer – there appears to be no way to make it reload your javascript file that you’ve just changed unless you go to “File->Clear Browsing Data”, uncheck everything except “Empty the cache”, click “Clear Browsing Data”, and wait, and wait, and wait. In normal web browsers, you just have to hit shift-reload on your page and it will reload that page and all the attendent files, including CSS and JavaScript files. That’s it, I’m switching back to Safari (or maybe Firefox) for the page I’m developing.

Oh, plus the built in “Developer Tools” in Chrome suck in comparison with Firebug, but that’s apples to oranges since Firebug is a plugin.

Spot the irony

Update: It turns out that the way I’ve been creating the smart playlist, with “Genre = Podcast”, which worked for years now, suddenly stopped working. Changing it to “Media Kind is Podcast” and making it sync under the Podcast tab worked.

Thanks to the latest iPod and iTunes updates from Apple, the iPod, the very device that “Podcasts” are named after, has become useless for listing to podcasts the way I want to listen to them.

The way I like to listen to podcasts is in the car, while driving, a time when I probably shouldn’t be poking around the screen of my iPod instead of watching the road. But Apple, in its infinite wisdom, made podcasts different from music or audiobooks in that you can’t (by default) click “Play” on them and listen to them one after the other. Instead, you have to pick one, hit play, and when it’s done, find another one, hit play, and lather, rinse and repeat. Until a few days ago, I had a very nice work-around: I made a Smart Playlist that contained “Genre = Podcast + Playcount = 0”. It worked great.

But now there is a new update for the iPod and iTunes, and they’ve broken it. The playlist still shows, and I can still play it in iTunes and it plays all the way through and the ones you listen to remove themselves from the playlist. Beautiful. But even though that playlist is still checked to sync to the iPod, the playlist doesn’t show up anywhere on the iPod. So how the fuck am I supposed to listen to an hour and forty five minutes of podcasts, some of which are only 3 or 4 minutes long, without spending time poking around on my screen instead of watching where I’m driving?

Maybe it’s time to find a podcast app for my Palm Pre.

This can’t be right

Is there anybody out here who knows anything about Subversion? I’m very new to it, and I think I might be used to better revision management systems like ClearCase and Git. Here’s the situation: My boss asked me to fix this project so that it could be built with Maven instead of Ant. One of the important things I had to do to was to move src/com to src/main/java/com, and move test/com to src/test/java/com, which I did using the “svn mv” command. I foolishly assumed that since I used Subversion commands to move the directories, that Subversion would then know that things had been moved. And when I merged my branch into the trunk, it appeared to work. But now somebody else just finished work on a branch that he branched off before my work. So we go to merge his stuff into trunk, and basically Subversion appears to think “ok, he made changes to src/com/foo/bar/baz.java, but that directory doesn’t exist any more, so it’s irrelevant, so discard it” instead of what I expected, which was “ok, he made changes to src/com/foo/bar/baz.java, but src/com has been moved, so I need to merge that into src/main/java/com/foo/bar/baz.java”.

Is there a way to make Subversion do the revision management, or am I going to be manually merging this guy’s changes for the next two days?

Google Chrome: not ready for prime time

Here’s what I discovered after a day of using the current beta of Google Chrome for Mac:

  • It frequently lost the text cursor in text input fields, especially on GMail.
  • It seemed much slower and more likely to corrupt the display compared to Safari in Google Wave.
  • It had a bad habit of undocking a tab on the slightest provocation.
  • The fact that the tabs take up space in the window frame means that you’d frequently undock a tab when you were trying to move the whole window.
  • It doesn’t have a “Reload all tabs” option. Supposedly there is an extension to that, but in order to use extensions I’d have to upgrade to the latest development build. That’s more work than I’m willing to do when it has all these other problems.
  • It doesn’t recognize or tell you about RSS feeds. In Safari or Firefox, any page that has an RSS feed displays an icon, and if you click it, the OS opens the feed in the currently configured RSS reader. The functionality is so ingrained in browsers that many pages don’t seem to have any other indication that they have RSS feeds. Once again, I’m told that Chrome has a plug in for that. Once again, too much trouble.

About the only thing I liked about Chrome more than Safari is that when I restarted it, it would re-open the three pages with 15 or so tabs between them that I had open beforehand. Safari can be trained to open the one page with 10 tabs that is my main window, but then I have to manually fiddle with the other pages. Oh, and Chrome opens new links in a tab instead of a window – that’s nice that I don’t have to hold down command when I click.

The main reason I was tempted to use Chrome is that using a busy wave in Google Wave causes browsers to eat memory like crazy. In Safari, to recover that memory I have to close the whole browser. In Chrome, you can recover it by closing the tab. Nice, but I was closing the tab and re-opening it every few minutes because the “space to next unread blip” functionality would stop working. I have to restart Safari about once a week if I avoid Wave, and about once a day if I use Wave.

I find it deeply ironic that the two biggest problems I had with Chrome were with Google apps. Maybe I’ll come back to Chrome when it’s ready. But not now.
