At work, we've been working with the HP t55xx series thin-clients, mainly for one of our customers.
This article contains some things we've found to be very useful. It is not a real howto, but rather a collection of smaller items, telling you how to do certain things, and those things are not easy to find in the manuals.

There are 4 ways to reset a t5530 to factory defaults:

Open Control Panel, open the System applet, then click on the button that says Reset. When powered off, press and hold the F9 key on your keyboard, then power up the device, and keep it pressed, until the  ...

Ever so often, owners of a HP Laserjet 1020 or 1022 may run into a problem with the print spooler crashing over and over for no apparent reason. Restarting the spooler causes an immediate crash, and the only way to get rid of the problem is by removing (sometimes by force) all printers. The observant type has already noticed (the title of this post says it all) that the common dominator is indeed the 1020/1022 printer, and that the problem usually occurs upon attempting to print one or another PDF document.

In truth, the problem is caused by newer versions of the HP Host-based printer drive  ...

HP has an online warranty check tool, but it's not easy to find on their website. Here's a direct link to it (for as long as it works:

Suppose you have an APC UPS and have just purchased a battery pack to go with it. Connecting the battery pack is pretty straightforward, but did you know you need to tell your UPS that an additional battery pack has been installed? Setting this in your UPS, optimizes the usage of the entire battery capacity.

If you are using PowerChute software, and have connected the UPS to a computer using serial, USB or network interface, you will be able to set this parameter in the software.

Log into the management card using your web browser (default user and password: apc).Navigate to UPS, and inside   ...

Finally got the final parts of my computer: the HD's.

Currently, I was using an old HD (a Maxtor 500GB) from my previous system. The idea with the new disks is to set up two Raptors in a RAID0 configuration. As Raptors are already fairly fast, the additional RAID0 - I've been using this method a few years already - should give it an extra edge.
I'm keeping the old HD in to have additional 500 GB of pure storage (like downloads and such, things that don't need the speed).

Going forward with plans for a new gaming computer, I've ordered the components. I didn't really have a specific budget in mind, other than the fact that I'm going for quality and performance, rather than selecting components based on their price.

Case: the case is an Antec Twelve Hundred gaming case. I always wanted to select a gaming case for the next one, but a nine hundred would have been just fine. The only reason why it's a twelve hundred is because of a wrong delivery a few months back, where the Antec PSU being delivered was an EC one (thus only fits in a select few cases of Antec).

Crap! Looks like my 8800GTX video card is broken. That's a serious bummer.

The card does some very serious funny things: as soon as going in-game, the card doesn't really freeze up, but has some sort of memory corruption problem, which remains throughout reboots.

Very coincidentally, I just ordered new hardware for my new gaming computer. The only thing not being replaced was the video card, because I thought it would be better to just wait a while until the next generation of cards from nVidia were available.
Apparently, Fate has decided otherwise.

For all those who recently acquired a WET54G (rev 3.1), or are planning on acquiring one, should read the problem I had with it.
The problem only affects EU versions of the product, as the US version has a more recent firmware available which fixes the problem.

Update: there's still no new firmware. I've updated the links so they are correct again.
And here's a direct link is here.

Anyway, the main symptom is the lock up of the device as soon as a connection with a wireless network has been made, and that network uses WPA-PSK or WPA2-PSK. I've tested this out extensively  ...

During the course of the lifetime of a Windows Installation, you're bound to stack up on one or more devices that no longer exist. Additionally, some device (existing or not) with an attitude, could very well make your life a living hell.
Luckily, there's a solution, with this cool software:

Acquired a new appliance from Mini-ITX, which is to replace my current WRT54GL (flashed with OpenWRT White Russian).

Specs of the thing are:

Durable industry-standards housing, including a mount bracket for 2.5" disks2x 1000 Ethernet, 4x 10/100 Ethernet, 2x USB 2.0, VGA, PS/2VIA chipset with a VIA Eden 1ghz CPU, 1x DDR2 slot, 1x CF slot1x IDE 2.5" port, 1x SATA portI've equipped it with 512 MB RAM (standard was 256 MB), and a 4 GB CF card, and installed Debian Lenny i686 on it.



Because of the fact it's CF, I've tweaked the initramfs image of Debian so it uses overlaying for /var  ...

For all nVIDIA users, I suggest installing the hotfixes recommended by nVIDIA: link.

If you have SLI, first install KB936710 (that's hotfix 2 on the nVIDIA page).

Most importantly, install KB940105 (hotfix 1).

And finally, there are KB938194 (hotfix 3), and KB938979 (hotfix 4).
