Windows Vista's Problem Reports and Solutions displays an empty dialog
I suppose this means it didn't find any solutions.

Finished experimentation project

Yesterday I put the finishing touches into my latest article, Motion capture-aided mobile user interface analysis. Those interested can view and download the document.
Motion capture nodes on a Nokia N95
In the course of the past year, I researched the viability of using a motion capture lab for performing user interface analysis.
My method relies on recording motion capture data synchronously with the device's video and accelerometer stream using a on-board application for Symbian. With a OpenCV-based application, the motion capture data can then be projected onto the video after camera calibration. This allows for analysis of the sensory information, using the motion capture data as a ground truth.
This technique has significant benefits over conventional computer vision techniques, and is elaborated in the article.
I'll put the source code of the various applications online after improving the documentation in the coming weeks.

Double-clicking executable JAR files

Since I installed Nokia's PC Suite, double-clicking executable JAR files no longer worked. The only way I could run them was via the command line:
java.exe -jar [JARFILE]
I spent a little time looking into fixing it until I ran in to this excellent program: Jarfix. It solved everything with literally one click of a button.

Subversion and Subclipse on Mac OS X

Installing SVN and Subclipse side-by-side on a Mac is a painful endeavor. But fear not: this guide will hopefully make things easy. Once you know the right order of things, it's really not so bad.

Install Subversion

Head over to RubyRobot's nifty tutorial for installing Subversion on Mac OS X. You can download the client straight from that page.
As of this writing, the newest Subversion client is version 1.6.1. That's working fine for me: we need at least 1.6.0 to avoid running into the renowned "format (No such file or directory)" incompatibility between 1.6.x and older versions.

Install Subclipse

Start up Eclipse, and install Subclipse 1.6.x according to the instructions at Tigirs. Make sure you select the newest Eclipse update site URL; as of this writing, that's http://subclipse.tigris.org/update_1.6.x.
In short: open up Eclipse's Software Update window, add the URL to the update sites, select Subclipse and hit Install. You will need to restart Eclipse for changes to take effect.

Checkout your project

It's best to check out your project from Subclipse, but you can do it using Subversion if you prefer. If you do it from the Finder or through the terminal, just make sure to import your project (or, if you already have a project, to refresh it) when the checkout finishes.

Review

You're done! If you're getting the "format (No such file or directory)" message, make sure you've installed versions 1.6.x of both Subversion and Subclipse.
I don't recommend doing SVN updates outside of Eclipse while it's still running. If you do, refresh your project to avoid "out of date" SVN errors.

On April 15th, Electric AlleyCat presented their debut album, One Size Fits All. Together with film school student Wisse Stolk we recorded the concert and just generally had a great time.
It will be mounted by the guys at EAC and will appear on their website when it's finished. These are some frames from the shoot; it was a pretty cool show!

Nokia PC Suite 7.1.26.0 fails to install

After the previous Nokia PC Suite update, my Nokia 6300 could no longer synchronize via Bluetooth. Upon reading that the 7.1.26 update fixed several connectivity problems, I was excited to install the new version.
When the download completed, however, the installer didn't show up and nothing appeared to have happened. Checking for updates downloaded the same version, but again, no cigar.

After some messing around, it turned out that my anti-virus was causing the updater to fail to launch. The same happened for the updated version of Nokia Software Updater.
Simply disabling my anti-virus allowed both installers to proceed.

Folders opening in new Explorer window

I've been having some strange Vista behavior recently. Double-clicking or pressing enter on a folder in the Explorer would open the folder in a new window, but clicking on in the navigation pane wouldn't. Even stranger, right-clicking on the folder and selecting "Explore" worked normally.
I tried the following solutions, finally fixing it with only the last suggestion.

Folder options

Open the Explorer. Go to the menu Tools, then click Folder Options. Under the General tab, ensure that the option for "Browse folders" is set to "Open each folder in the same window" is selected.

Registry

Open the Registry Editor and navigate to:
HKEY_CLASSES_ROOT\Folder\shell
Make sure that the data for the value (Default) displays as (value not set). If it doesn't, right-click on (Default) and select Delete.

(Re)register DLL

Open a command prompt with administrator privileges. Type the following command to (re)register actxprxy.dll into the system:
regsvr32.exe actxprxy.dll
You should receive a notification that the DLL has successfully been registered.
I'm unsure how this may have become unregistered, but I suspect it may have happened unjustly during some uninstall.

Vista displays UAC notification for Update.exe

During our development for QuickGene here at CrimsonBase, we ran into a curious issue under Vista.
When our automatic update program is run from the Program Files directory, Vista displays the following UAC notification:
UAC notification for update.exe
Executables with update in the filename trigger UAC
The problem, we discovered, is that files compiled with update in the filename trigger UAC. You can't simply rename the file to avoid the UAC pop-up; you have to recompile the executable using a different filename.

New room!

After moving from temporary room to temporary room, I finally have a permanent place. Previously, I had lived in various student houses in Lunetten: on the Hondsrug, Boven Zevenwouden, Oeral and Pyreneen. Now I've once again returned to the Hondsrug to settle in to my very own little corner of Utrecht.
I have my own back door, a small patio, and my room opens out into the kitchen. Perfect!

Diagnose connection problems in Internet Explorer

Post replyCan't edit post
Watch topicCan't delete post

Connection problems in Internet Explorer are fairly difficult to diagnose, despite the convenient "Diagnose Connection Problems" wizard that displays when a page fails to load. There are some reasons IE can't connect that won't show up after the wizard completes, so here are some pointers.
First, make sure your internet connection is working by using a proper web browser such as Firefox, Opera, Safari or SeaMonkey.
If you can open pages in other browsers without problems, but Internet Explorer is giving problems, follow the steps below. These solutions may concern you if you are receiving the following message:
Internet Explorer cannot display the webpage
Internet Explorer reports 'Internet Explorer cannot display the webpage'
A Windows Update or add-on may be causing connection problems in Internet Explorer

Check Windows Updates

This may sound silly, but check if you have rebooted your machine after finishing any updates. In some cases, IE is blocked or stops working until a reboot is performed.
You might also want to check for new updates that affect Internet Explorer, and reboot if you install any.

Turn off your anti-virus / firewall / network software

Make sure your anti-virus or firewall programs aren't blocking access to the Internet. If they are, consult the developer's website for a solution.
A network guardian such as PeerGuardian, PeerBlock or NetLimiter may be restricting HTTP access. Check whether you have anything of this sort running.

Check third-party add-ons

You can easily disable all add-ons by starting Internet Explorer with the following command:
iexplore -extoff
Run this command by hitting Windows Key + R on your keyboard to open the "Run..." dialog, then entering the command and pressing OK.
Make sure any instances of Internet Explorer are closed and that the iexplore.exe and ieuser.exe processes are actually terminated in the Task Manager before starting it in this mode. You should get a message that add-ons are disabled.
If the connection is working fine, then one of your add-ons is messing something up. In my case, Orbit Grab++ was messing up my connection. You can disable the third-party add-on by going to Tools then Internet Options. Open the tab Programs, then click Manage add-ons. From that list, you can look around for a problematic add-on and disable it. Restart Internet Explorer in normal mode to see if it fixed the problem.

Clear the cache

Just to make sure that the cache isn't causing the problem, clear it out. Go to Internet Options again, and hit the Delete... button on the General tab, under "Browsing history". Then click "Delete files..." to remove all the Temporary Internet Files. (This won't delete your session data, passwords, etc.)

Proxy connection

If all else fails, make sure that your proxy connection (if you need one) is set up identically to the functioning browser. Unless your internet connection passes through another machine in your household, you typically don't need this set up and it will only cause problems. In that case, make sure it's switched off in the LAN settings of Internet Options, under the Connections tab.

Once you're done using Internet Explorer, reward yourself by quickly resorting back to Firefox.
