Key things

- I touch on CUDA and trying to get it to work with SLI’d NVidia configuration.. It’s there, just a lot of work to get working, and I didn’t..

- the machine isn’t working with Ubuntu Studio in the realtime kernel like I had expected.. I tried both 64-bit and 32-bit versions of 9.04..

- The realtime kernel gives me all sorts of “DRDY” messages.. Stuff like
[ 90.703396] ata4.00: status: { DRDY }
I think that my deprecated BIOS (XFX dropped support for it) is probably to blaim. So if you get a 750i, get the Core2Duo’s, you’ll probably have a better experience. My next machine may be AMD based.. Seems like AMD has it more together than Intel.

- Got “Mass Effect” running in wine (toward the end of this video).. I’m surprised that the computer was fast enough to capture the video without the audio falling off..

- (not covered in the video) steam wouldn’t install with positive confirmation from wine-doors, but it did anyhow.. IT works.. I downloaded gecko with winetricks, I couldn’t get wine-doors to do it.. I installed Art Rage 2 demo, with Wine-doors (that did install). MASS EFFECT was downloaded over a period of about 10 hours on Friday..

- Art Rage 2 recognizes pressure sensitivity from my Intuos 3, I made no special changes in the X config (I had to do that back with 7.10, but 9.04 seems to support the wacoms better). Someone was asking me if I was able to get it to work because she hadn’t.. So I tested.. And it works.. However GIMP doesn’t seem to work now.. Hmmmm.. Maybe I don’t know how to turn it on. Heard that Canonical is moving away from the xorg.conf and changing the way programs are configured that have to use X. So wacom support now is not from X but from within the Kernel or somewhere in Ubuntu.

- I demonstrate GISH.. After I had trouble getting mass effect to work the first time. BTW, the last time I ran Mass effect, the protagonists face was black (it wasn’t being rendered with a texture). This time was the first time I had seen the faces in full..

- Last, I show off the “super_pi” of the system.. I think a i7 is .68, and Core2Duo is like .88 . So 1.03 is not bad for this machine.. But keep in mind “super_pi” only tests the power of one processor (with a select set of operations) so it’s not a determining factor of the power of the computer.

Why are people still terrified to make a change? Especially our cooperations?

by admin

Kernel Source

Why the hell are people still SO SCARED to try out something new??? say linux… i mean if you truly look at the concept and philosophy of an open source the possibilities are endless. Its somehow like comparing a closed family owned business to a cooperation. DO you see the big picture here? look at how much linux have evolved in this short amount of time. compare that to a closed sourced company. glitches and bugs will be fixed on the fly.
There are couple of old sayings that say: United we stand and we are strong, break up to pieces and we are weak. The second one would be, Sharing is truly caring. Just imagine the power of gathering all these intelligent and smart programmers working for a single cause. Imagine a guy in china fixing up the kernel to suit their specific chinese governmental and educational districts, while another guy in brazil using teh same kernel and source code to Compile something that would suit their needs. Now imagine teh power.1 world that stands united.

Sounds nice, but better for the computer/technology forum.

Is there Windows boot software that can boot a linux kernel?

by admin

Kernel Software

I want something like GRUB for linux but I am wondering if there is any windows software that I can use to boot windows and linux?

One more vote for Wubi. Dyne:bolic claims to be able to be run from inside Windows but I’ve never been able (or frankly interested) in running it from anything but a CD. Debian has a similar installer at http://www.goodbye-microsoft.com and OpenSuse has instalinux, but I really don’t recommend them.

Microsoft really doesn’t want you to run anything but Windows. They are not going to release a boot loader which accommodates other OSes. Linux can do it because it has such a radically different model of what a computer is. I wouldn’t look to Microsoft for a boot loader. Your choices are grub lilo and running Linux on top of Windows.

How the save the uploaded image with ramdom name?

by admin

Kernel Developer

I have an upload script and it” saving the filename with the original filaname+temp name. I need it to be changed as just temp name because special characters are causing problems and if there is a spacial character in the filename browsers can not read the image.

Here is the code:

it’s funny but all that code you pasted in there is totally irrelevant to your problem..

Anyhow I went and looked up this class for you here, http://www.xoops.info/doc/nav.html?_classes/index.html and researched the problem..

After this – $uploader = new XoopsMediaUploader

slide in this:
$uploader->setTargetFileName($value);

Where $value is the random file name you wish to use.
A very simply way to create a random string would be:
$value = mt_rand(5, 15);

Keep in mind you will need to concat the extension onto that random number!!!

How To Dual Boot VISTA X86(C:) With XP X64(D:) Vista Installed 1st.?

by admin

Kernel Options

I Installed VISTA 1st On C Drive.Then Installed XP64 On D Drive.But After Installing XP VISTA Boot Kernel Disabled.I Know This Is Normal.It’s Always Recommended To Install Earlier Version OS First.But Several Ways I Followed Already.Also used EasyBCD And VistaBoot Pro.But None Of Them Worked.I have Previous Experience With Dual Booting With 98,ME,2000,XP Etc.I’m Already familier Wth All Of Those.But As U Know The Vista Boot Kernel Can’t Be Directly Modified Via BOOT.INI. There Might Be A File Called Boot Manager In Vista. I Know The Easiest way To Get This Probs Solved Is,Reinstall Vista While Leaving XP64 Installed On My System.But Is There Any Other way To Put The XP64 Boot Option In Vista Boot Manager as "Earlier version OS".Pls Help Me To Continue R&D With VISTA Dual Boot.

why not just use virtualpc? it’s free and then you don’t have to keep booting:
