Yesterday I bought a Linksys 54-g card for the laptop. The installation is very simple: just do a setup with the supplied CD, reboot and insert the card. Windows then recognizes the card and uses it. But when I switch to using WEP (since the AP is), it would not connect to the AP. After much trying and changing settings, I found that you just have to wait a little longer than I expected. A proper reboot after changing the settings and then waiting until the connection is made did the trick. After that first wait-till-I-get-my-settings-confirmed-with-the-AP, things are smooth. Reboot until network-up-and-running is faster than with the 3Com card. And the link quality is a lot better: signal strength and link-quality in the 90%-range.

Great, now we can surf the internet downstairs again, without bugging the connection to the computerroom upstairs.

How could I have missed this one: WSE 2.0 is out for download. WSE is a supported enhancement to VS.NET and the .NET Framework, so for secure applications you’d better install/use it.

Yesterday, I converted the application I’m building for a client from using TRichView to WPTools, after succesfully using both next to eachother in one window.

Although WPTools is only $45 (225 vs. 180) more expensive, it offers not only more components to make your programmers life easier, but it has better RTF-compatibility as well. TRichView (as confirmed by the author when I asked him about it) has problems with very thin table-lines (if you set the border to 1 or so). And it can’t handle headers and footers well, as I blogged about before.

In a couple of hours playing with the WPTools-components, I had more functionality in my application than ever before with TRichView. And when I asked the author a question in the middle of the night (actually, it was about 01:00), the answer was already in my mailbox this morning (at about 06:55). And I thought I had little sleep!

If one is interested, I can draft an article that shows the differences in more detail then described here. So drop me a line/comment if you would like to see such an article.

I changed the Linksys AP and the ethernet-bridge to use WEP (10-bits) and found that the performance was like I thought it should be: I have a 2-8mbit (downstream) ADSL connection, and I was seeing downloads in the range of 400-500kbyte/sec with peaks to around 800-900kbyte/sec.

This is the graph:

Problem now is that the laptop has a 3Com 11mbit network card, so I have to buy a 54g card, since it does not connect to the AP when WEP is enabled. It sees the AP, recognizes the signal-strength (excellent!), but it does not connect.

If you have a lot of images or pictures on your PC, you probably have some program to organize and modify them. Why not try FxFoto? It’s simple, and there is a FREE version. The pay-versions are only $29 or $39!

I didn’t want to blog about it yesterday, but after tightening the antenna on the Linksys Ethernet Bridge (54g) the connection seems okay again. Some strange zero-bytes-per-second periods still, but when it works, it works great. See this DU-meter screenshot:

In case you downloaded and installed the Delphi 7.1 update, go and download this one as well, since it seems to fix the bug that cause the “persistent field size mismatch exception”.

Today I cleaned the CCD of my Fuji S2 Pro. I was annoyed by the same spot on every picture. At first I thought my Nikon 28-105 was the suspect. So I shot this image:

But both the 28-105 and my Tamron 90/2.8 gave the same image, obviously the spots where CCD-related and not lens-related.

The procedure for cleaning the CCD is simple, but…you need to take precautions. First you need to be in a clean room. Second, the camera need not be used recently. Third, you need to hook up the camera to AC-adapter. And fourth, you need special swabs and cleaning fluid. The second precaution was a simple one: the camera was used this afternoon, not recently. The first one, well, if I consider my computer room clean, then this condition is met too. Third condition was a difficult one: I don’t have an AC-adapter for my camera. Fourth condition, well, none of that present here too.

I thought, what the heck, let me just look at the CCD and try to blow of the dust. Pressing the Flash-settings and LCD-light button whilst turnin on the camera was the first step. I removed the lens, pressed the shutter, and the mirror stayed up. A nice redish CCD was looking at me, rather innocent, but with one big dustspot on it. I blew (no canned air, just my lungpressure) into the camera, to find that it would not remove the dustspot.

Scratch, scratch. Wait, I’ll get some Q-tips.

After removing the spot, the CCD-image looked like this:

So, I followed the procedure to flip up the mirror again and wiped the whole CCD area, no matter if I saw dust or not. The resulting image:

Clean enough for me!

DISCLAIMER: THIS IS NOT THE PREFERRED WAY OF CLEANING THE FUJI S2 PRO CCD. I TAKE NO RESPONSIBILITY FOR ANY DAMAGE TO YOUR CCD IF YOU FOLLOW THIS PROCEDURE. SCRATCHING THE SURFACE OR AN OTHERWISE MALFUNCTIONING CCD MIGHT BE THE RESULT IF YOU FOLLOW THIS PROCEDURE. DO NOT TRY THIS CHEAP PROCEDURE IF YOU CAN NOT AFFORD A NEW CCD WHEN THINGS GO WRONG.

If you run IIS on Windows XP, and you test your applications with it, you will suffer from the maximum connection limit of 10 users sooner or later. It can be altered to 40, but that’s a not so documented feature. Download MetaEdit from Microsoft, and change the inner-settings of IIS. The MaxConnections can be found under LM\W3SVC.
