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.

Defragmentation with UltraDefrag
by lunarg on August 28th 2009, at 11:51
If you're looking for a better defrag, check out UltraDefrag:

Some highlights of the software (as told on their site):

Boot Time Defragmentation allows for defragmenting upon boot (like an antivirus), useful for system files, like the registry, the pagefile, ...Option to shutdown the computer once defrag has completed.Aside of defragging, there's also compacting, which rearranges data to the beginning of the disk, increasing performance and stability;Single file and folder defragmentation, in case you only need to defrag an application or files that have   ...
 
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
by lunarg on April 29th 2009, at 19:48
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  ...
 
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.
This dis  ...

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

In the sample above, I'm forwarding port 2  ...
 
Time sync with an NTP server using w32time
by lunarg on April 9th 2008, at 11:25
The following was tested on a Windows 2003 R2 with SP2, but it should work on every system with w32time installed.

Open up a command prompt (start, run, cmd.exe, you know).

Then punch in these lines:

net time \\your-server-name /setsntp:some-ip-or-pool.ntp.orgnet stop w32timenet start w32time

The way NTP works, the sync does not occur immediately, but it should be visible within a few minutes after w32time has started again.

Notice

If it doesn't work for you, check whether your time zone is correct, and whether the time of your server and the real time differs with over 3600 seconds.  ...

[Gentoo] No module named collections error with portage
by lunarg on March 26th 2008, at 13:17
Had an issue on my PC at work with a corrupt reiser4 filesystem (still no clue as to why). I managed to repair the FS using RiP-Linux, but not without some data loss. After reviewing lost+found, I found most files related to some HTML cache of Konqueror, but fsck.reiser4 complained about a file that could not be recovered.
After awhile, I tried running emerge to install some new package, and there it was: a broken portage...

The error I got:

Vista: printing to shared network printers
by lunarg on March 13th 2008, at 11:30
When printing from a Vista computer to a shared computer, you notice the following:

Printing takes a long time to begin.Opening the Print dialog (e.g. in Word) takes a long time.Selecting printers in the Print dialog is slow.The real reason is unknown, but Vista seems to have a problem with excessive querying of the printer. Along with the usual slowdowns of network traffic, this causes serious slowdowns.

The trick is to have Vista believe it is dealing with a local printer, rather than a shared printer. This is done by specifying a Local printer port, pointing to the share, then configure t  ...
 
Reiser4 sources still available...
by lunarg on March 6th 2008, at 10:36

Namesys, the commercial developer of the Reiser4 filesystem, still has its website down. However, the source code and development is still going on, and can be retrieved at:

http://chichkin_i.zelnet.ru/namesys/

A good thing, because it would be a shame to lose such a good filesystem...

nVIDIA in Vista
by lunarg on December 28th 2007, at 21:46

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).

 
Notes about latest ATI linux driver
by lunarg on December 28th 2007, at 17:35
This article contains some notes about the latest 7-12 ATI linux drivers. Biggest change in versions after 8.40 (aside of the new versioning scheme), is the support for Composite and AIGLX extensions, and the supposedly improved 3D performance. Unfortunately for some, support is currently limited to newer Radeon cards only.
Installation on my X700 was not entirely straight-forward, though.

Installation took place on my laptop which has a X700 on-board, but the driver only worked properly after some tweaking of xorg.conf...

Since I'm using Gentoo, installation of the latest driver was fairly   ...
