Sync databases with Outlook/Exchange
by lunarg on December 16th 2009, at 14:58

I came across this application when I was looking into software that does just that:

http://www.geniusconnect.com/geniusconnect.asp

It enables synchronization of Outlook/Exchange folders with a relational database; anything with an ODBC driver is supported (MS-SQL, MySQL, ...).

 
Next-gen gaming
by lunarg on December 15th 2009, at 21:08
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).

8800GTX broken
by lunarg on December 14th 2009, at 23:26

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.

 
Creating ISO's on a Mac
by lunarg on December 6th 2009, at 22:28

Create a folder with the contents you want on your ISO.

Open Disk Utility and use the New Image from Folder menu item to create an image. Ensure it is uncompressed and use the CD/DVD master option.

In my experience this creates HFS+ masters which are no good in Windows.

Open the Terminal

Assuming your new image is called ~/Desktop/Master.cdr (the file is on your desktop and called Master.cdr) type:

cd ~/Desktop
hdiutil makehybrid -iso -joliet -o Master.iso Master.cdr

This will create an ISO/Joliet .iso file.

Using TWAIN with Word 2007 in Vista/7
by lunarg on October 30th 2009, at 13:26
Since Office 2007 (and Vista), TWAIN has been kicked out in favour of WIA. As a result, it is no longer possible to use your favourite and robust TWAIN based scanner with Office 2007.
Most scanners come with the necessary software, and thus, you can circumvent the issue by using their software. However, there are various scanners - notably, office network scanners, like those on copiers, do not have such a tool. They have their driver's internal system which is callable in other software (like Office-applications). In the event that the driver is only supporting TWAIN interface for image acqui  ...
 
MacOSX: unlocking locked files
by lunarg on October 28th 2009, at 15:50
Ran into an issue where I could not unlock files that were copied from a network location to local disk. The files were marked as being locked, but I was unable to unlock them (through Finder), even though I had all proper rights. Additionally, chmod as root (= user with the highest privileges) did not work either.

The solution to my issue was to manually override the locked flag of those files, from within a Terminal.

sudo chflags -R nouchg my-problem-file-or-dir

Additionally, I found that it sometimes is easier to completely reset/clear an ACL, and start over, rather than trying to fix th  ...

BSOD in a VirtualBox guest when it has been moved
by lunarg on October 5th 2009, at 21:49
When running a Windows XP or 2003 in VirtualBox, under certain circumstances, the guest may generate a BSOD when booting. The message of the BSOD is a:

DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS

It is accompagnied by a referral to processr.sys, intelppm.sys or p3.sys, depending on the CPU used to install the machine.

The reason for this BSOD is a problem with these drivers, trying to perform an unsupported operation inside the virtual machine (like updating microcode or changing the power state of the CPU).
The issue usually surfaces when the guest machine is moved to a different  ...
 
Locking down Firefox

Found this article, showing you how to lock down Firefox.

This is quite useful when deploying Firefox on, for instance, a Terminal Server.

 
Keep-alive issues when proxying IIS with Apache2
by lunarg on September 8th 2009, at 18:26
We had a bit of trouble with an Apache2 server, configured as a front-end proxy for a IIS running various different sites. The idea for this has grown because of the fact that our client had only one public IP address at the time, but had to run multiple sites. Rather than running the sites in IIS on different ports, we setup the Apache2 to proxy requests to the IIS back-end, so the sites were accessible by means of sub-urls.
E.g.:

http://myserver/mysubdomain1/ -> http://internal-ip:my-port/

For this, we used mod_proxy, and the ProxyPass and ProxyPassReverse.

Lately, our client complained o  ...
 
Set up VNC in Mac OSX
by lunarg on September 7th 2009, at 20:34
Did you know that since version 10.4, Mac OSX has a VNC server built in? It was originally implemented to have remote control and management. Since 10.5 (where Apple Remote Desktop was implemented for remote managing), they have renamed it to screen sharing, but the principal remains the same.

To enable it, follow the instructions below.

The following guidelines are for Mac OSX 10.6, but they are roughly the same for other versions.

Open System Preferences.

Find the icon that says Sharing.

In the list of services at the left, select and enable Screen Sharing by ticking its checkbox.

Get rid of stale devices
by lunarg on May 17th 2009, at 12:41

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:

Router appliance

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

Specs of the thing are:

Extended characters in Terminal Services
by lunarg on September 18th 2008, at 16:35
When you're using a Belgian keyboard (or another) on a Windows 2003 Terminal Server, you might have the same problem we had: characters that are formed with a combination of AltGr and other characters (e.g. the @ sign) don't work as they should.

There are two things you can do to work around this problem.

Instead of using AltGr, try using CTRL+ALT and the key you want. This circumvents the problem, but may not be what you want.

You can change the application of Windows key combinations. Rather than applying them to the TS, you can change it so it applies only to the local computer.

Installing r8168 driver in 2.6.24
by lunarg on May 1st 2008, at 14:22
Currently, the Realtek R8168 driver does not work in a 2.6.24 kernel because of changes in the kernel structures. I found a patch on the Ubuntu Forums which adjusts the driver source so it can compile for a 2.6.24 kernel. The patch was written for 8.005.00, but I verified it working for 8.006.00 (latest version at time of writing). The patch is attached.

Download driver here.Got the patch from here, but for your convenience, I've attached it to this article too.Note that these instructions are also found on the page at Ubuntu Forums

After unpacking the driver, copy the patch in ./r8168-8.006  ...
 
When OS'es can speak...
by lunarg on April 22nd 2008, at 22:40

What would an OS says or think when copying files - let's say, about 100MB of MP3 - to an SD card?

DOS

What's an SD card?

Linux (bash)

....
....
Done.

Windows XP

Alright. Wait around a bit, and it'll be done. Don't ask me when, because I'm terrible at guessing.

Windows Vista

What? Me? Do you have any idea what you're asking of me? It requires careful planning: first see whether it all fits on your card, then calculating the time, and even then, I'm not sure if I'll do it. Maybe you should check back tomorrow; maybe I've gotten around to it by then, just maybe...

 
Virtualbox: set up port forwarding when using NAT
by lunarg on April 17th 2008, at 12:56
If you're using NAT for networking with your VMs, you need to use port forwarding if you want to access a VM from the outside network. This is a quick and dirty howto on how to do this in linux.

Fire up a terminal, and enter these commands:

VBoxManage setextradata nvm3 "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/HostPort" 28080VBoxManage setextradata nvm3 "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/GuestPort" 28080VBoxManage setextradata nvm3 "VBoxInternal/Devices/pcnet/0/LUN#0/Config/ssh/Protocol" TCP
