Something to remember: escaping entities (e.g. when you have table or field names that are the same as reserved words) is possible using square brackets

Some examples:

CREATE TABLE [User] ...
SELECT * FROM [User]

I had to use this while renaming logical names, which had a dot in their name.

In VMware ESXi 4.1, by default, the video drivers are not correctly installed. This is because of the fact that the old driver (which is installed by default) is a WDM type of driver. This type of driver has been kicked out of Windows 7 and Windows 2008R2 in favour of the newer WDDM driver architecture. As a result, the video is reverted to the Standard VGA adapter, which has terrible performance.

However, installing the VMware Tools does provide a correct driver, even though it is not installed by default. To install it, see the second chapter of the article: Windows 2008 R2 console freezes in vSphere console.

Users of a Samsung Galaxy Apolly GT-I580x may have noticed that, by default, there's no YouTube player present. This basically cripples the phone not being able to play YouTube videos.

A standalone version of the application was released by Google, but can only be installed on Android 2.2 (Froyo), really disappointing for 2.1-users.
Fortunately, someone has ported the YouTube player to 2.1 by removing some 2.2-specific function calls and replacing others that are required by the app.

To install it, download the attached Android package onto your phone and install it. You may have to install Apps Installer from the Android Market for this to work.

The application works very well b  ...

While not officially supported, it is possible to have Adobe Flash on your Android 2.1 (Eclair) device.

You can do so by downloading and installing the package included in this post. Note that you will have to have third party applications allowance enabled so that you can install it. Possibly, on some devices, you have to install Apps Installer to install the package.

Flash player works, but because of missing components in 2.1, there are some performance issues.

One of the neat things about OpenOffice is the many extensions available. Oracle has a PDF import extension for OpenOffice Draw, which can import just about any unsecured PDF document.

Download link: http://extensions.services.openoffice.org/project/pdfimport?intcmp=1549

This allows you to open PDF documents directly from the menu. There are still a few quirks now and then, but they don't spoil the usefulness of the extension.

It is available through Windows Update, but for those that require the full installer, can find it here: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=c3202ce6-4056-4059-8a1b-3a9b77cdfdda&displaylang=en.

To reset the printer (does not reset the Jetdirect network card), turn off the printer. Upon turning it back on, immediate press and hold the green go button for at least 10 seconds but no more than 20. During that time, the attention light will go on. When that happens, release the button and the printer will cold reset.

Resetting the network card is done a little differently. With the printer in the ready state, press and hold the rotate carousel button and the cancel job button at the same time for a few seconds, then release it. This will reset the card to factory defaults (BOOTP/DHCP, no management password). If a network cable was inserted, you'll notice the LED at the NIC port   ...

Since Acrobat Reader X, by default, no toolbar is shown while in Read Mode display. Instead, a heads-up black toolbar with minimalistic functions is used. This is the default behaviour but can be turned off.

To do that, open Reader, choose Edit, then Preferences. In the tab Internet, uncheck Display in Read Mode by default, then press OK.

Because the official website of 7-Zip (http://www.7-zip.org/) is currently offline, I'm mirroring the latest version here.

EDIT: the official site has been fixed and is online again.

For an easy to use disk erasing tool: http://www.dban.org/.

It's pretty important when you retire your old computer that you securely delete the contents of your hard disk. Even with a regular format, it is still possible to retrieve a lot of data from the disk. DBAN can help you with that.

By default, there's no ODBC driver available on 64-bit Windows systems for Access and Foxpro. This is because they only are native 32-bit at the moment. There are a few workarounds present, but the easiest would be to stick with 32-bit if you need this.

If you're having trouble with your Mac and think the cause could be hardware-related, you can run the Apple Hardware Test. It's a set of tools by Apple which perform basic and extensive tests on your hardware to see whether they are still okay. These tools are available for anyone with a Mac, and are either preinstalled on your system, or available through your OS'es installation discs.

Applies usually to older models of Mac.

You can download the AHT disc images for a number of older Mac models through here: http://www.info.apple.com/support/aht.html.

Insert the Apple Hardware Test disc into the CD drive.

Upon starting/restarting your Mac, immediately press and hold C on your keyboard. K  ...

Debian has introduced incremental updating of package lists. While in theory, this is a great feature, it is not always practical.

Incremental updates enable to download less data by fetching only the differences between the previous versions of the list. This results in significant savings concerning the amount of downloaded data.
The unfortunate downside is that a whole lot more fetches need to be done as each incremental update requires a server request. This becomes apparent when you don't often download package list updates, and there are suddenly a whole number of files waiting to be downloaded. The overhead of requesting each incremental slice separately causes the update to take mor  ...

More information about the search at Belgacom: it took place last wednesday (Oct 14), after a complaint of Mobistar and KPN at the Raad voor Mededinging (a counsil which keeps an eye on companies keeping to Belgian competition laws).

The investigation is about the wholesale services of DSL where Belgacom alledgedly would have invoked obstruction measurements.

The search is only a step in the whole investigation, without actual accusations. The entire procedure could take several years before completion.

At work, I'm currently deploying a Windows 2008 R2 on a VMware ESXi 4.0, and noticed an odd behaviour. At irregular intervals, the console of the guest OS simply locks up and doesn't do anything anymore. Networking and remote access seem to work fine, it's just the console that is freezed. Restarting the vSphere client doesn't help, and the only way to get rid of the problem is by hard-resetting the VM. The issue only occurs on Windows 2008 R2, the other VMs run fine.

The problem is caused by the VMware SVGA II driver, and has two underlying issues: the driver itself, and an apparent lack of video RAM (due to the new HW-accelerated GDI of 2008R2/Win7).

The most quickest way is to get rid o  ...
