Getting started: BlackBerry Native SKD 1.0 with a simulator

2011-10-22T13:44:00.005-04:00

NOTE: This is still a work in progress..

This took some trying....then again i have no idea how to develop in an Eclipse based IDE. I wish there was more documentation but i figured I would get started with a simple how-to on developing for RIM's new OS.

Getting the simulator up and running:

Getting the Native SDK up and running:

Trying out a sample app:

So I decided to try out the one of the sample apps on the Blackberry webpage, namely the Hello Native SDK Graphics app.

From start to finish this is what you need to do and I will try to be as details as possible (this is for the noobs like me out there!)

Unzip the Folder into your NDK workspace
We will be using the Managed code (because we like life being easy now dont we?). Import the project into the QNX IDE by going File -> Import -> General -> Existing Projects into Workspace -> Select the root directory to be the HelloNativeSDKManaged and click Finish.
In the Project Explorer window you should see the Project. First off right click on it and set the Build Configuration to the Simulator (Build Configurations -> Set Active -> Simulator).
Build the project now (right click then Build Project). You will notice in the project folder on the HDD there will now be a Simulator folder.
Next we set the target device. Right click on the project and go BlackBerry Tools -> Configure Targets.. -> select "sim (Neutrino/x86)" and hit ok.
Now we configure the runtime. Right click and select Run As -> Blackberry Tablet OS C/C++ Application -> Tadaa !!

Install linux without CD/USB/Floppy !

2009-05-29T21:30:00.002-04:00

As part of a bigger project (a digital photo-frame) I have been trying to repurpose an old P3 laptop of mine that has not seen use in a few years. It had a semi-working install of Fedora Core 4 on it and I wanted to install something newer, faster and something where I could get software easily.

Heres the catch, the laptop's CD drive went bust a long time ago and being a 2001 model it has no USB boot capability. All it had was a functioning internet connection (ethernet). After a week of searching and understand how Grub boots linux I successfully installed Xubuntu on the machine !

Background:

Will keep this as simple as possible. Grub use a config file /etx/grub.conf that contains the commands used during bootup. what we need is a paragraph starting with title and contaisn the name of the distro being booted. ANything can be written here.

The next two lines below it are the locations of the Kernel and the Initrd files. These are what linux always boots first and are the key to installing a new system. They specify the location of the root partition on the hard drive for example: (hd0,0) meaning hard drive 0 and partition 0. Heres a sample of a paragraph:

title Red Hat Linux (2.4.18-0.12)
      root (hd0,0)
      kernel /vmlinuz-2.4.18-0.12 ro root=/dev/hda3
       initrd /initrd-2.4.18-0.12.img

Now all we need are the 2 files ( the kernal and the initrd file of the system we wish to boot ).

Proceedure:

First and foremost get the two files ( the kernal and the initrd file ) of the system you want to install. Two ways of doing this: if you have the distro's image (iso file ) just go into that and find them files.
Place both files into the /boot folder in your root directory.
Open up /etc/grub.conf in your faveroute text edditor.
Add a paragraph in it. Heres what it should look like:

title My Linux installer of choice
kernel   (hd0,0)/boot/your_linux_kernel_filename
initrd   (hd0,0)/boot/your_initrd_img_filename

Now simply reboot the computer. When the Grub menu shows at startup simply select your newly added choice. A simple installation menu should start up and all you have to do is follow the instruction. The distro will eventually start the installation by downloading necessary components from a provided mirror.

NOTE: I know Ubuntu can automatically find mirrors to install from but I had issues with Fedora where I had to manually enter a mirror. In that case go here and select the mirror for the distro required. Make sure that the url you provide is of the os and should look like this: .../blabla/fedora/linux/core/10/i386/os/

Closing notes:

Im glad to have the laptop working again. The installation went smoothly and I was able to format the entire disk meaning the kernel and initrd files i had booted from were wiped out but during the install they were on the ram so it dint cause any issues. Make sue that the install goes uninterupted though, failing in the middle can be catastrophic.

I hope this helps. I took help for this from this website. It is more comprehensive and also explains how to do this from Windows if required.

Fedora core 10 crashing at boot (Kernal issue)

2009-05-28T12:30:00.003-04:00

FC10 seems to have this issue sometimes where upon bootup it hangs after:

Creating root device.
Mounting root filesystem.
mount: error mounting /dev/root on /sysroot as ext3: No such file or directory

Not sure what is happening here but I found a quick fix.

Edit the grub line for FC10 being booted up
Edit the kernel parameters
add at the end scsi_mod.scan=sync

Should boot up just fine now.

Creating an ad-hoc wi-fi network on Linux

2009-02-24T21:43:00.004-05:00

A simple how-to on ad-hoc networking.

First of all the basics, ad-hoc networks are not are slightly different from regular networks. In its simplest form an ad-hoc network possesses no DHCP server i.e. each computer has a static I.P. address and to talk to another computer it simply attempts to contact the other I.P address. No need of a switch in the middle to act as a mediator.

Now for a computer to be on the same ad-hoc network the following must be set:

Wifi mode should be in ad-hoc
The Essidof the network should be the same (duh ?)
They should be on the same channel

a quick setup would involve the following 3 lines:

ifconfig wlan0 down
iwconfig wlan0 mode ad-hoc essid testing channel 5
ifconfig wlan0 192.168.10.10 up

Here "wlan0" is my wireless card, replace it what you have ( Type in "iwconfig" if you are certain what it might be ). The essid is named "testing", type anything creative here ( its the name of the wireless network and is visible by all so dont be too creative ). The channel# can be anything that wont be affected by local interference ( eg a local wifi router ). Lastly bring up the wifi card and choose an I.P address for it.

Do the same thing on the other computers except change the I.P address ( for eg make the next computer 192.168.10.11 ) and this way your ad-hoc network can grow.

P.S. make sure the computers are on the same cell. Type "iwconfig" and see the entry under "Cell". It should be the same for all computers on the network.

In the case that the computer misbehaves and doesnt connect to the network, destroy the network manager:

killall NetworkManager

Opening and Closing ports in Ubuntu

2009-02-23T16:12:00.002-05:00

Took me a while to figure it out so i figured I should share it with everyone. Ubuntu has something called UFW ( Uncomplicated firewall) which can be activated at any time and told to open/close ports.Some of the basics:

sudo ufw enable

sudo ufw allow 53/tcp
sudo ufw allow 53/udp

sudo ufw status

These basic commands can be used for opening ports. See the link for more details (including how to open ports for services automatically )

Engineering project for 2008

2008-08-09T19:54:00.000-04:00

Here was my submission for my 4th yr engineering project. Its a multi-input interface that studies the applications of a touch-less interface in user-PC interactivity. Keep in mind this interface does not have to be limited to PCs itself and could also be used in interaction with other electronics such as TVs etc.

Enjoy!

Trying to run your DirectX or other VC++2008 app on another computer ? Heres what you need....

2008-08-05T23:20:00.000-04:00

I was trying out some of my Wii project code on another computer today. Its a directX app that uses the Wiimote input for interaction and i kept getting the errors

This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.

Heres the sollution:

rebuld the application in release form and not debug form. in visual C++ 2008 go to Build > Configuration manager and in the "Active sollution configuration" select "Release". Now rebuild the app. You may several errors, they are covered earlier int the blog.
Heres the important part. A VC++2008 app requires certain libraries to run on another computer and if that computer doesnt have visual studio you get the Microsoft Visual C++ 2008 redistributable package and this will provide your app the proper envirnment to run in.

Well have fun running the apps on different computers. Shout if anyone needs something else.

Image scalling/translation using Wii remote and hands

More coming soon. meantime enjoy the video:

2008-07-19T15:06:00.000-04:00

ever get the frusterating error:

error C2664: 'CWnd::MessageBoxW' : cannot convert parameter 1 from 'const char [12]' to 'LPCTSTR'

Heres a sollution:

Change your project configuration to use multibyte strings. Press ALT+F7 to open the properties, and navigate to Configuration Properties > General. Switch Character Set to "Use Multi-Byte Character Set".

Another issue when doing 3d programming is when the libraries in Visual Studio do no import the necessary functions and you get Link errors. heres the sollution:

Change your project configuration to use multibyte strings. Press ALT+F7 to open the properties, and navigate to Configuration Properties > Linker > Input. The option Additional dependencies should read "$(NOINHERIT)". click it and select the "..." button that appears beside it.This shows all the dependencies available. Make sure the checkbox "Inherit from parent or project defaults" is checked. The code should now compile.

Opening a serial port in C#

2008-06-24T23:56:00.002-04:00

Just a quick tutorial, I was trying to communicate with my LCD in C# and heres the gist of how i got it up and running:

Use the Header using System.IO.Ports; we create an object using the name serial_port which looks like:

SerialPort serial_port = new SerialPort("COM7", 9600, Parity.None, 8, StopBits.One);

Here we specify the required vars - Com port name, Baud rate, Parity bit, Data bits and stop bits. Now we simply open the com port serial_port.Open(); and this allows us to read/write from the selected port. For my purposes I used write commands so as to write data to my external LCD screen. Keep in mind the write command accepts only strings so I had to improvise as I was sending it a integer value.

serial_port.Write( i.ToString() );

where 'i' is the integer I am sending accross the COM7 port.

Establishing a basic connection with the Wiimote

2008-06-08T19:32:00.004-04:00

Been working on coding for the Wiimote using C# and have thankfully made some progress. Import the wiimote library and create an object for the wiimote

using WiimoteLib;

Now in the main function

wm.Connect();
wm.SetReportType(InputReport.IRAccel, true);
wm.SetLEDs(true, false, false, false);

This establishes the connection with the wiimote and the SetLeds tells the wiimote to show the first of four lights on the controller.

x = wm.WiimoteState.IRState.IRSensors[0].Position.X.ToString();
y = wm.WiimoteState.IRState.IRSensors[0].Position.Y.ToString();

This saves the coordinates in our strings x and y. You can take a printout or do whatever you want with these values now, still not sure what rate the wiimote is streaming the data at though.

Capstone Project: Headtracking using Wiimote

2008-05-04T02:24:00.000-04:00

I am creating a project similar to Johny Lee's headtracking project using the Nintendo Wii remote for my final year engineering design project. 1st step is ofcourse to get the remote up and running with the existing applications created by Mr Lee. The following steps are required:

Establish a bluetooth connection with the wiimote. Use the tutorial here to accomplish that. After you sync the Wiimote the lights on the remote will continue flashing as if its in sync mode, this is normal as the remote only syncs to controller 1 after the application interfaces with it.
Download and install the latest .NET version and the DirectX SDK for the application to run properly. I spent a lot of time figuring out why the application kept crashing upon startup and it turned out i needed the DirectX SDK and not just DirectX 9.0c .
Fire up the WiiDesktopVR.exe

The next few posts will include a dissection of the code in order to fully understand what is going on here.

Publishing .NET to an IIS server woes..

2007-12-20T11:30:00.000-05:00

Been having trouble at work getting an ASP.NET project to publish on a local dedicated server but ive finally found the simplest method. here goes:

1. With ASP.NET 2.0 there are no precompiled assemblies and everything is runtime compiled so all one needs to do is copy the project folder across to the \intepub\wwwroot\ folder on the server.

2. Make sure >NET 2.0 has been installed and is linked to IIS. You will know its working when under the IIS manager>Web Service Extensions it shows ASP.NET v2.0 is allowed. If there is no green check mark then select and allow it.

3. Now comes the part where everyone screws up. The .aspx file is now accessible but will always return an error when accessed from the local server or elsewhere on the network. The reason is the virtual directory containing our project files on the server has to be configured as an application in the IIS in order for the ASP code to be compiled at runtime. You will see something like this :

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Source Error:

Line 49: ... Line 50: --> Line 51: Line 52:

To get around this simply right-click on the website folder under "Default Web Site" in the IIS manager and under the Directory tab under Application settings select create and this registers the application with the IIS.

The website should be up and running now. Hope this helps.

The hidden artistic side of technology

2007-06-29T10:42:00.000-04:00

To most of us technology is something we come across everyday yet something so un-human if we take a moment to step aside and see how much we interact with it compared to humans we would truly be shocked.

Yet like most of human-kinds creations there is an artistic depth in technology as well. It is not just something cold or hard to the touch but there is so much happening in the background that we may not necessarily see or hear, I speak of forms of expression beyond our perceptions. Enter the IBM 1401 mainframe from the 60's. A scientist using them in Iceland saw that during the operation of the mainframe, memory leaks were causing signals to be broadcast on AM frequencies. Now with some modifications the result :

Additional composition samples available from Johann Johannsson's website. His father was the one who discovered this back in the 60's.

Xbox 360 Intercooler Mod

2007-03-22T22:58:00.000-04:00

Been hearing a lot of negative stuff about the Nyko intercooler for the Xbox 360 and after doing some digging around i came to the conclusion that having a 3rd party hardware sucking up and disturbing the streamlined power being sent to the console using extremely powerful fans which might have variable power inputs depending on their quaity is good enough to ruin ones 360. But we still need the intercooler as Microsoft has pretty much abandoned us when it comes to cooling their monsters down.

Hence I modded my intercooler. Here are the steps I took :

First off i thought I would simply open the intercooler and disconnect its fans. With the help of an opening I brought the wires out and tried to feed them power via USB.

there was a black and brown wire that I cut and brought out through the opening. The connections inside looked solid ( for the remaining cables ) so i decided to leave everything intact. I closed the intercooler, powered up the USB and gave it a test.

It could have been a disaster, the USB was maxed out at 5V while the fans needed 12 volts at .13 amps each ( power hungry monsters, another reason i dont want them sucking off my 360's power ) and the USB couldnt supply them with enough. The 360 actually became hotter than 2 hrs of Gears of War while it was simply idling !!

I had no choice, i needed a stronger power supply. The sollution : a cheap 350W computer power supply. I rigged the thing to turn on when connected and attached the fans to them and boy was there some cooling to be seen !! An hour of Ghost Recon AW and the 360 felt cooler than it does when its on the dashboard doing nothing !!

All was good but there was still a problem. The power input for the 360 was still comming through the intercooler and i wasnt too happy with this. Given that the cases where the intercooler fries the 360 its power plug leaves a burn mark on the 360 that voids the warranty I decided to get rid of it.

So with the aid of a saw from the dollar store i started off. I cut off the following portion...

.....and was left with....

this way the 360's power cable goes in directly and surprisingly the intercooler seems to be able to balance without its plug going into the 360.

Conclusion : the system is much cooler now and in multiplayer i have actually seen a performance difference ( Played Ghost Recon AW and some huge explosions caused everyones 360 to lag for a second, even the hosts but mine barely stuttered :) Also this allows me to run the fan for a few minutes after i turn off the 360 so that the heat does not stay inside when the internal fans turn off.

Let me know what you guys think.

Xbox 360 with VGA out

2007-02-15T13:01:00.000-05:00

I recently tried out my Xbox 360 with the monster VGA cables on a 22" LG LCD monitor. I have heard several people complaining about the washed out look the VGA cable provides but I have come to realize that it is the LCD monitor that makes the difference. The below pics are of what gaming looks like in the LCD :

Honestly Gears of War looked great. The last level especially was the best test to see if the colors in the sky look rich and vibrant and I would place them around 80% as good as what I have seen on a Samsung 40" LCD tv. The LG lcd ( L204WT ) has a dynamic contrast ratio of 3000:1 and the dark colors look great in comparison to samsung LCD ( 225BW ) but the main thing is the f-engine which increases the richness of the color and makes the experience more HDTV like.

I also tested a DVD on the monitor. Not sure if its true but the 360 upscales a DVD when using the VGA cable. In effect i get a 720p HDTV upscaled output from a 480p dvd. the following screens are from Star Trek Voyager :

The aspect ratio was fullscreen so i used the 360 to soom in to fill my screen and i could not make out any artifacts at all, its was purely amazing !!!

XGL and Beryl on my humble laptop

2006-10-27T23:11:00.000-04:00

Finally ditched compiz and installed the latest beryl using the help of this how-to and I am at a loss to explain the beauty i see in front of me !!

the effects are way beter than what compiz had to offer and there are some practicle ones as well such as the ability to select any open window from any desktop with just a single click of the mouse. beryl also comes with the eerald window theme manager which has some exelent themes available to choose from in the default package. have not tried to install new themes yet though.

Pictures cannot do justice to the hard work that has gone into this so heres a movie straight off my desktop

Note : for those installing beryl after trying out compiz like myself you need to remove compiz and xgl completely. i used the package manager and uninstalled them before proceeding with the how-to.

Compaq Presario V3000 with Ubuntu 6.06

2006-09-30T16:03:00.000-04:00

Got a new laptop last month. The specs are AMD Turion 64 X2 DUal-core processor with a Nvidia 6150 graphics card, 512 MB DR2 533MGHz Ram and a NForce4 chipset motherboard with inbuilt wireless and a 100GB SATA hard disk. Screen is a nice HP 14.1" widescreen Organic LCD display and its truly the best LCD screen i have seen around.

I tried installing FC5 onto it but there were complications as several modules such as the ethernet, sound etc dint work. so i decided to foray into uncharted waters and tried out Ubuntu 6.06. these were the installation steps i followed:

download the ubuntu amd64 generic cd and instal.
update the system
install the nvidia drivers and restart X

wireless is a problem and took me a while to figure out but its simple really. i had a lot of problems because i was using 32 bit driver instead of the 64 bit required.

.install all the development packages ( linux-kernel-devel & linx headers )
download the latest ndiswrapper source and extract it.
go into the extracted directory and do

make & sudo make install

. get the wireless drivers from Compaq's website as the ones on the windows partition are 32 bit ones and linux needs the compaq 64-bit versions to work. Get cabextract and get it to extract the compaq drivers exe file using the command

cabextract sp33008.exe

. there will be a bcmwl5.inf and a bcmwl5.sys file in the current foder. run the command

sudo ndiswrapper -i bcmwl5.inf

this will install the drivers and doing

ndiswrapper -l shows

Installed drivers:

bcmwl5 driver installed, hardware present

Now run

sudo ndiswrapper -m

Reboot the laptop.

Upon startup run

sudo modprobe ndiswrapper

the wireless modles are now working. run iwconfig and there should be a wlan0 with wireless extensions. yu can now connect to a network using

sudo iwconfig wlan0 essid name-of-essid
dhclient wlan0

Sound gave a little trouble. Apparently there a bug in ALSA ( pre 1.0.13 versions ) which cause trouble with the headphone jack. The 1.0.13 version fixes this problem though and can be downloaded from here. Compile and install it and it creats a "sound" script in the /etc/modprobe.d folder. Open this file and add :
options snd-hda-intel index=0 disable_msi=1

Failure to add this results in the sound playing for half a second and getting stuck in an infinite loop. Well now the headphone jack works, its just wierd that the laptop speakers and headphone jack dont have the same control but different controls. Also the laptop speakers dont shut off when one plugs in a headphone, since their volumes are independent.

Now for the 64-bit issue. A lot of problems arise out of using a 64-bit kernel which basically highlight how behind the world still is in 64-bit computing.

For starters i had a bad time trying to find a video player as the 32-bit codecs for wmv, mov and others dont work here with any midea player ( Xine, Mplayer, Vlc, etc ). The sollution was this : I installed that cool software called Automatix. I dont remember how I got it but just google it I guess ( If you try it and get it working please send me a msg and I will edit this post ). In Automatix there is an option for a 32-bit Mplayer and its codecs, install it and your video should work.

Then I also was unable to view flash media on firefox. The solution, install a 32-bit version of Swiftfox and flash as well. This can also be done through Automatix.

Aside from this I have not really come up against any hurdels on accound of using a 64 bit kernel. Again let me know if any other problem arises.

EDIT : this stuff on XGL/Compiz is old now, my next post has some goddies on XGL/Beryl.

Have XGL running on it now with tons of effects. The matrix screensaver is running as a background pic almost and these streams of matrix code beautifully flow over everything. The last 2 pics are of the multiple desktops in action in XGL using the inside walls of the cube and the outer walls of the cubes ( watching a movie on 1 desktop and browsing files on the other ).

Fedora Core 5 - Nvidia drivers and XGL

2006-07-29T02:44:00.000-04:00

Of all the Fedora distros FC5 i rekon got the most attention. was it because of the sleek elegant look ? the official Fedora logo appearing for the 1st time or the fact that it is filled with bugs ? not sure what the answer is but one thing is for sure, there is a lot of potential here !

Coupled with Xorg 7.0 FC5 is a perfect distro to run XGL on 24x7 like I do. there were several roadbocks though, especially since i was previously unable to install the Nvidia proprietry drivers and had to rely on the lesser versions from Livna. the problem is that FC5 has more security features. 2 cases where this shows - manually adding new lines to the fstab file to include more devices at bootup would usualy fail and the proper nvidia driver modules and the GLX extensions never loaded upon bootup. i have fixed that fro now by dissabling SELinux but a proper fix is available at Nvidia's forums. installing XGL is easy to install, its all at fedoraforums .

Overall FC5 has been a rough ride till now but ive finally setelled in. I must have been the first person at my Uni to install it ( had installed it on my 5-yr old P3 laptop without a CD/DVD drive :s ) and now there are 3 computers running FC5 at my place. all i can say is "keep it up" !! and I look forward to FC6.

Wine Beta Testing - Palm Desktop

2006-07-27T13:11:00.000-04:00

well, ive always wanted to try out the palm desktop program in linux and the linux variants like gpilot/kpilot have always had some defficiency or the other. for my palm zire 31 there are several features such as mp3 and video playback and over the last year i still havnt figured out how to dump such files onto the palmtop in linux. as a last resort i tried out the palm desktop with wine and the results are not good :( .

running the autorun file : running the singlelaunch file : running the /palm desktop/setup file

as one can see palm doesnt seem to concenterate at all on other plaforms apart from windows as this shows. sadly we are just going to have to wait in the dark till they realise their that Posix and Mac OSX also has some following with palmtops.

Wine Beta testing - Star Trek Elite Force - Expansion Pack

2006-07-15T12:56:00.000-04:00

finished beta testing the expansion back and everything seems to be in perfect order. ive completed most of the single player stuff in the expansion plus spent quiet some time trying out multiplayer with wiki's and ranjan's help. the end result is that elite force completely is an excelent game for linux. few problems exist, ones which i cant put my thumb on :
1) cant connect to multiplayer servers hosted by windows computers. they however can connect to my linux hosted server via LAN.
2) multiplayer doesnt display new modes ( dissentegration, hero, class-based, borg, etc ) for the expansion pack however this problem is not secluded to linux as the windows based test computers also dint show these options. i am at a loss why my linux installation and the 2 windows installations dont show these features.
never the less, ive given the game a rating of Platinum at the WineHQ database. it is perfectly stable and a solid game, something i hope other linux users will enjoy as much as i have.

Wine Beta testing - Star Trek Elite Force

2006-07-11T01:09:00.000-04:00

As the Maintainer of this software at the wineHQ i am pleased to announce that i now have star trek - elite force ( version 1.0 ), the quake3 based FPS game fully running on wine under linux fedora core 5 and wine 0.9.12. i have hereby given it the ranking of platinum at the wine website.

Remotely controling a Windows server with RDesktop in Linux

2006-06-28T04:07:00.000-04:00

was checking up on the terminal services offered by win2000 and stumbled accross rdesktop. with a simple install i was able to log into the server as a proper user and the speed of the terminal os much beter that VNC as it is a proper terminal ( VNC was just taking snapshots of the desktop and sending them accross )

while its fast and doesnt require me to have a keyboard attached to the server everytime i restart, there are 2 problems. i cant increase rez ( its 800x600 ) and sound doesnt seem to work. since its a terminal i think its supposed to send the sound through the network even :s i have to figure out a way for it to use the sound card of the server itself.

Xorg TV-out configuration utility

work continues, after a 1 month break :s
i have now implemented a checking header that checks the scanned xorg.conf file for the presence of propietry drivers. seems small but it took hours !

work is progressing slowly. just figured out how to read the xorg.conf file in parts. next objective : store these sections into temporary files where they can be modified.

Remotely controling a server with VNC

2006-06-23T23:50:00.000-04:00

Just bought a cheap P2 server today and have windows2000 server running off it. in order to control it i have to change my lcd screen to its input and use a seperate mouse/keyboard but not any longer. i installed "TightVNC" on the server and now i can control the server from FC5. on FC5 i installed the X Viewer, opened it, entered the i.p add of the server and the password which i installed the vnc server and connected :

still have to conduct experiments whether this can hold if i restart the server. its been a long way since Radmin though.

Wine Beta Testing - Bryce 5.5

2006-06-23T22:42:00.000-04:00

Well, another reason not to boot up in windows now !! :-D i managed to get Bryce 5.5 running in wine 9.15 under FC5 with XGL running :

Am going to try out some modeling on it soon but there are several problems. some of the menus crash when clicked with the left key and the network rendering engine is inoperative. the network rendering was a priority for me as i do most of my designing on my laptop that has XP also. looks like i will use my linux desktop for the designing now and will then use a group of networked windows powered computers to do network rendering.
note : the setup required a msvcirt.dll file to be placed in the win32 directory in order to run. apart from that theres nothing special required for installation/running.

XGL powered Fedora Core 5 Linux

2006-06-19T02:57:00.000-04:00

After a rough time trying to get XGL working with Suse 10.1 i decided to switch back to Fedora which i have been using for over a year now. to my plesent surprise i found out that i could install XGL on fedora too so i went for it. this is done by ework at fedoraforums. simple proceedure really but in the end it was effective as these would prove.

I experienced some problems with certain programs. Mercury, my java based messenger showed up as a blank screen and xine is giving trouble with certain clips and its external controller is comming all screwed up so for now i am using Mplayer which is running perfectly stable.

Torrents, Azureus & Firewalls

2006-06-18T04:25:00.001-04:00

Just brainstormed with everyone to get the D-Link router i have to open its ports so thet we can do torrent based downloads. for the record, the steps are :

1. open 192.168.0.1 in firefox and log into the router, password - admin
2. go to advanced config at the botom and enter - port used by azureus ( 49152 ) my i.p. address and click save and then reboot.
3. in azureus set TCP/UDP to 49152 and under Plugins->Distributed DB-> unclick default port so it can use 49152.
4. under firewall settings add 49152 under TCP & UDP
5. Restart azureus

Quake 3 Source - XREAL

2006-06-18T04:25:00.000-04:00

Phew ! managed to get XREAL working. downloaded 4 pk3 files from http://xreal.varcache.org/ which form the interface and 3 test maps and for the textures i linked the Doom3 pk4 files into XREAL's base as .pk3 files. The Results :

While it deffinately looks sweet, the engine seems to be frought with bugs in the rendering systems. several inactive or background meshes seem to be popping through left right and center. my immediate assumption is that the hidden objects are not being culled properly and are "popping up" when hey shouldnt be. either way, after what ? 5 years of waiting, i have finally been able to compile and run the Q3 engine on my own :)

Quake 3 Source - XREAL

2006-06-18T04:24:00.000-04:00

Just got the quake3 source to compile on linux!! in the end i had to use the "CONS" make installer and i have to say its a neat installer. just installed the cons rpm and fired up the quake3 source installer as the instructions mentioned and voilla !

NOTE : i have not compiled the actual Q3 engine but a highly advanced version called XREAL. gonna have to get quake3 before i can start testing it.

DOSBOX - Wing Commander 3 on Linux

2006-06-18T04:22:00.000-04:00

Just installed Dosbox 0.65 on FC5 and am trying out Wing Commander 3. While the gameplay is kinda bad ( jerky, sound stutters amongst other stuff ), its still fun to re-visit one of the 1st games i ever played.
Just found out that i cant play the game on wine. apparently my version is the original version built specifically for DOS unlike the khilrati saga version which is ment for Win95. just my luck to get stuck up with the original version .

Wine Beta testing - Halo

2006-06-18T04:20:00.000-04:00

The biggest roadblock i have run into with Wine uptil now is getting Halo up and running. Halo is just about the only reason i still wish sometimes i could log into Windows and sadly i have not been able to get it up and running uptil now.
Today i made some slight progress with getting the intro sequence of Halo up and running, barely. the intro clips can be heard but the monitor is blank and once these are over the game exits to gnome with an "Unhandeled Exception" error or something. Tested with wine "9.12" on the "2.6.16-1.2111_FC5smp" kernel.
Well, its beter than the success i had on FC4 with wine 9.10 so i guess i should try the game with any new release to see if more can be done. heck, Thushan also said he wanted to play halo on Gentoo linux on his desktop so im glad i have some support from his side. Just hope we can get it running some day...........
