Subversion: This client is too old to work with working copy ‘XXX’
October 27, 2008
I thought I’d thoroughly read this article, but upon reading it again today, I noticed a key point I’d missed. If you can’t upgrade your SVN client, do a fresh checkout with the older client. I’m going to have to try this now…
This client is too old to work with working copy ‘XXX’
The full error message is:
This client is too old to work with working copy ‘.’; please get a newer Subversion client.You will get this error message once you have used a Subversion client linked with a higher Subversion version, and then try to execute a command with a Subversion client linked with an older version, e.g., you used an 1.4.x client on your working copy, and now you try an svn 1.3.x client on the same working copy.
The reason for this is that Subversion 1.4 and 1.5 upgrade the working copies transparently on every command. But once the working copy format is upgraded, older clients can’t access the working copy anymore because they don’t know the new format.
The only solution to ‘fix’ this is to upgrade whatever clien

Came across this while debugging a program today in Eclipse:

E18 Error Fixed! (Canon PowerShot SD450)
October 23, 2008
Huzzah! I finally fixed the E18 error I’ve been experiencing on my Canon PowerShot SD450, which prevented my lens from extending when the power was turned on, and the fix wasn’t nearly as difficult as I had expected. I’ve even snapped some shots of the process so that you can follow along at home, and fix your own camera if you are experiencing the same problem that I was.
If you’re not yet familiar with the E18 error, check out this information on the topic from Wikipedia:
The E18 error is an error message on Canon digital cameras. The E18 error occurs when anything prevents the zoom lens from properly extending or retracting.[1] The error has become notorious in the Canon user community as it can completely disable the camera, requiring expensive repairs.
This is a fairly prevalent problem with the PowerShot cameras, and a class action lawsuit was filed (but dismissed) against Canon:
A Chicago law firm, Horwitz, Horwitz & Associates, has already filed a class action,[4] while the law firm of Girard Gibbs & De Bartolomeo LLP are investigating this camera flaw and may issue a class-action lawsuit against Canon.[5] There is at least one other.[6] Although the suit was dismissed in a court of law, the plaintiffs are appealing.
Fortunately, at least in my case, the fix did not require returning the camera to a Canon repair facility or having to take unreasonably complex steps.
My solution for the PowerShot SD450/IXUS 55 follows:
(You’ll need a very small Philips head screwdriver, #00, to remove the screws)
- There are six screws holding the metal frame of the camera body together, two on each side, and two on the bottom. Remove all screws, pop the strap-hook plate (sorry, probably not the most technical term there), then gently lift the front plate off by pulling up from the bottom, and remove the back plate in the same fashion. These should come off relatively easily. This is what the camera should look like as you remove the plates:
- Now, looking from the top of the camera, you should see a small motor on the left side, as shown below (it’s beneath the cable with a “22” written on it):
- Take your screwdriver (or another small instrument) and gently try to rotate the plastic piece attached to the motor on the left side, as shown below:
- At this point, try placing the battery back in the camera (if you have removed it), turn the camera to one of the capture modes, and press the power button. If all went well, your lens should now be able to extend and retract properly.
Further information (and other repair tutorials) are available at the following locations:
- Canon PowerShot A70 Error E18 Fix (Translated from Bulgarian)
- Canon E18 repair guide for SD300 [PDF]
- CNET: Digital cameras: Fixed my SD450 e18 error
- Canon and the E18 Error / Lens Error, Restart Camera
- Canon E18 Error Dialog
- Canon E18 Error: Repair Instructions
- E18 Error
- E18 - Repair Guide part 1
Unforunately, the site that had the most comprehensive information about this issue, e18error.com, seems to be down for the time being. Here’s a quote from their site that I saved in another blog post before the site was taken down:
HOW IT ALL WORKS:
Canon E18 error happens when the lens gets stuck while trying to extend. The camera will beep a few times and the LCD will display a little E18 in the lower-left corner. The lens gets stuck in the extended position, and refuses to move either to focus the lens or to retract when powered off.Apparently, people who posted about this incident on forums say they had to send the camera for repair and that Canon has horrible customer support and response time.
Here is how the E18 error looks like. You just get a black screen with small “E18″ sign in the lower-left corner:
The problem usually happens because dirt or sand get into the lens mechanism. But it seems that more and more people are showing, who took great care of their camera, and still started receiving E18 errors.
Please share your experiences with this fix, or the E18 error in general, in the comments below. Thanks for reading!

Nice!
WordPress 2.7 New Post Screen
As you may know, we’ve been working behind the scenes on the design and development of version 2.7 of the WordPress software that powers your blog. The administration interface you’re used to will be changing as a result of your feedback and the results of the usability testing we conducted over the summer. Version 2.7 is due to release officially on November 10, but in the meantime, we’re posting sneak previews of the look and functionality to come. So far we’ve covered the new navigation system and the new Dashboard. If you want to get an early idea of what you can expect come November, head over to the WordPress.org blog and check out The Visual Design of 2.7 and The New 2.7 Dashboard.
We’ll be publishing more descriptions of how things will work over the next couple of weeks so that when the change comes it won’t be a complete surprise. We’re also working on new Help materials that you can use for reference (replacing FAQs, screencasts, etc.) while you adjust to the new structure. Overall, the response so far is that the new interface is easier to use, and that it’s faster to access the screens people use most, so hopefully once you’ve checked out the posts linked above, you’ll be as excited for the launch of 2.7 as we are.
Disable Ubuntu System Beep!
October 20, 2008
If you’re like me, you’re probably quite annoyed with the system beep in Ubuntu. Luckily, there’s an easy fix:
To disable it temporarily:
- In Terminal (or the console), enter: “sudo rmmod pcspkr”
- You should not hear the system beep until your next system reboot.
To disable it permanently:
- In Terminal (or the console), enter: “sudo nano /etc/modprobe.d/blacklist”
- At the end of the file, enter a new line “blacklist pcspkr”
- Type Ctrl+O (to save the file), then Ctrl+X (to exit nano)
- After your next system reboot, you should no longer here the system beep.
Thanks to Turning Off The System (hardware) Beep : Linux Tutorial for the info!

Microsoft Word: Strikethrough Shortcut Key
October 18, 2008
This is freakin’ awesome; I had no idea that you could assign keyboard shortcuts this easily:
From word.tips.net:
- Press Ctrl+D or choose Font from the Format menu. (If you are using Word 2007, press Ctrl+D or click the Home tab of the ribbon, then click the small control at the bottom-right of the Font group.) Word displays the Font tab of the Font dialog box. (Click here to see a related figure.)
- Hold down Alt+Ctrl and, at the same time, press the plus sign on the numeric keypad. The mouse pointer turns into a clover symbol.
- Click on the Strikethrough check box in the Font dialog box. (As you move the mouse pointer to get ready to click, the mouse pointer may change back to an arrow instead of a clover; this is OK.) When you click, Word displays the Customize Keyboard dialog box with the insertion point blinking in the Press new Shortcut Key box. (Click here to see a related figure.)
- Type whatever shortcut key you want to use for the strikethrough format. Just hold down whatever combination of the Alt, Ctrl, and Shift keys you want, and then press the desired key to go with that combination. If the combination is already taken, that information shows just below the Customize Keyboard dialog box, and you can then change to a different shortcut key. (A good combination to consider is Alt+Shift+S or Ctrl+Alt+S, neither of which are used in a default installation of Word.)
- Click the Assign button. The shortcut key is now assigned to apply strikethrough formatting.
- Click Close to dismiss the Customize Keyboard dialog box.
- Click Cancel to dismiss the Font dialog box.

BobAtkins.com: Manual focus lenses on Canon EOS bodies

Photojojo: Manual Focus Lens on Canon EOS DSLR
I found this excellent post below from BobAtkins.com about using manual focus lenses on Canon EOS bodies via this great article at Photojojo: Better Lenses for Less Money: How To Use Vintage Lenses with Your DSLR
Using Manual Focus Lenses on Canon EOS bodies
A common question is whether older manual focus lenses from other manufacturers can be used with a Canon EOS body. The answer is a qualified “yes” in many cases. Of course you don’t get autofocus, nor do you get any sort of focus confirmation. Also, you don’t get any sort of automatic iris operation. In most SLRs, focusing is done at full aperture, and if you stop the lens down to, say, f11, it remains fully open until just before exposure, then it stops down for the exposure and opens up again. This gives a brighter viewfinder image and makes focusing easier and more accurate. When these lenses are mounted on an EOS body, stop down metering must be used. That means that the lens is first focused at full aperture (for maximum accuracy), then manually stopped down to the shooting aperture before the shot is taken. Some people have trouble accurately focusing using the standard EOS viewfinder screen, since it has no focus aids (like a split image center). While some of the higher end models (like the EOS-1 series, the EOS 3 and the EOS A2), so have additional accessory screens with focus aids (e.g. screen Ec-B has a split image center), the consumer level cameras (Rebel, Elan, digital Rebel, 10D, 20D) do not.
Clearly using a manual focus lens is inconvenient, but sometimes it can be worth it if the equivalent EOS lens is expensive, if the manual focus lens is better than any Canon EF or EF-S series lens (rare, but it happens), if you shoot mostly static subjects or if you don’t use the lens very often.

Lifehacker: Firefox Mobile Alpha Screenshot
October 12, 2008
The alpha build of Mobile Firefox (codenamed Fennec) has been available for testing by brave Nokia N810 users for some time now, but Mozilla developer Brad Lassey just got it up and running on a Windows Mobile device, and shares a couple of screenshots. Obviously there’s quite a bit of work to be done, but it’s an exciting preview at what getting Firefox in your pocket will look like in the near future. [via]
