Configuring Linux to work with NVIDIA Hybrid SLI Technology

amree — Sun, 21 Feb 2010 14:31:13 +0000

First of all, at the time of this writing, NVIDIA Hybrid SLI Technology is not supported on Linux and without proper configuration, you won’t even be able to load your Desktop Environment such as Xfce.

That’s not the only problem, based on an interview with NVIDIA’s Tom Petersen, one of its main feature is called HybridPower which basically allows users to shut off the graphics card when not needed and dramatically reduce power consumption. This means, there is a possibility that if we can’t find a way to turn off the second GPU, it will consume more power that it should be. But that’s another problem. Right now, we want to boot into our Desktop Environment properly.

Running

amree@pikopong:~$ startx

(!!) More than one possible primary device found
(--) PCI: (0:2:0:0) 10de:06e8:1028:0271 rev 161, Mem @ 0xae000000/16777216, 0xd0000000/268435456, 0xac000000/33554432, I/O @ 0x00004000/128
(--) PCI: (0:3:0:0) 10de:0866:1028:0271 rev 177, Mem @ 0xaa000000/16777216, 0xb0000000/268435456, 0xcc000000/33554432, I/O @ 0x00005000/128, BIOS @ 0x????????/131072

gave me some errors from my

/var/log/Xorg.0.log

Login as a root and run the command below
```
root@pikopong:~# nvidia-xconfig
```
This is to generate the right configuration for your X.

Get the list of the GPUs.

root@pikopong:~# lspci
02:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 9200M GS] (rev a1)
03:00.0 VGA compatible controller: nVidia Corporation C79 [GeForce 9400M G] (rev b1)

You will get a long list of devices connected to your PCI buses. We are only interested with the VGA controller.

As you can see, we have two VGA controller, we need to specify which one we would like to use.
```
root@pikopong:~# nano /etc/X11/xorg.conf
```

Go to your Device section and set Bus ID for your controller in it. So, in the end, if I chose the second controller, my Xorg.conf would somehow look like this:

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce 9400M G"
    BusID          "PCI:3:0:0"
EndSection

The configuration is simple, you just need to add the 6th line. Just make sure you put it in the correct format PCI:X:X:X, X possibly refers to the last 3 digit number in your error log

How to enable MySQL support in Qt SDK for Linux

amree — Wed, 22 Jul 2009 07:21:47 +0000

Download Qt SDK for Linux/X11 at Qt Software.
Install it anywhere you want, just make sure you remember the path.

To build MySQL as a plugin, you need to know two other paths:

Your MySQL header files directory. It should be something like this:

decimal.h   m_string.h      my_dbug.h    my_list.h        my_sys.h     mysql_embed.h    mysqld_error.h  sql_state.h        typelib.h
errmsg.h    my_alloc.h      my_dir.h     my_net.h         my_xml.h     mysql_time.h     raid.h          sslopt-case.h
keycache.h  my_attribute.h  my_getopt.h  my_no_pthread.h  mysql.h      mysql_version.h  readline.h      sslopt-longopts.h
m_ctype.h   my_config.h     my_global.h  my_pthread.h     mysql_com.h  mysqld_ername.h  sql_common.h    sslopt-vars.h

Your MySQL lib files directory. Something like this:

libdbug.a    libmyisammrg.a      libmysqlclient.so@         libmysqlclient_r.a    libmysqlclient_r.so.15@      libmysys.a
libheap.a    libmysqlclient.a    libmysqlclient.so.15@      libmysqlclient_r.la*  libmysqlclient_r.so.15.0.0*  libvio.a
libmyisam.a  libmysqlclient.la*  libmysqlclient.so.15.0.0*  libmysqlclient_r.so@  libmystrings.a

For Slackware 12.2, it should be:

1 2	/usr/include/mysql # MySQL header directory /usr/lib/mysql # MySQL libraries

Go to your Qt SDK installation directory, mine is: /opt/qtsdk-2009.03/

cd /opt/qtsdk-2009.03/
cd qt/src/plugins/sqldrivers/mysql/
# Replace all the path based on your computer environment. 
# Make sure 'qmake' can be run from anywhere or you'd have to specify the full path for it.
qmake -o Makefile "INCLUDEPATH+=/usr/include/mysql" "LIBS+=-L/usr/lib/mysql -lmysqlclient" mysql.pro
make

You should have new files created for you:

Makefile
README
libqsqlmysql.so*
main.cpp
main.o
moc_qsql_mysql.cpp
moc_qsql_mysql.o
mysql.pro
qsql_mysql.moc
qsql_mysql.o

Copy MySQL plugin to your Qt’s plugins directory,

cp libqsqlmysql.so /opt/qtsdk-2009.03/qt/plugins/sqldrivers

Create new project and put these codes to test your new plugin

#include 
#include 
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
 
    qDebug() << QSqlDatabase::drivers();
 
    return a.exec();
}

You’ll get these outputs showing that your Qt has supports for MySQL

("QSQLITE", "QMYSQL3", "QMYSQL")

About the IT Department in Hospital Universiti Sains Malaysia

amree — Wed, 08 Apr 2009 01:21:56 +0000

Information System Unit of HUSM was established in year 2000 due to the specific needs of IT implementation in hospital. At that moment, there were only 4 people working, but today, the numbers has grown up to 25 people. Since the beginning of establishment, the unit has extensively developing applications software for the hospital. Lead by En. Azuddin Bin AB Rahman and his team consisting of 7 IT Officers, 13 programmers and 4 technicians, they have delivered more than 10 systems for various purposes. As computer science graduates, the team believes that they can build any application without the needs to acquire one from external sources. With that mindset, the software development alone has saved the hospital millions of ringgit.

We are using these frameworks/tools/languages/technologies in HUSM:

Linux Slackware
J2SE
MySQL
MySQL Replication
Perl and Bash
Python
Apache
XHTML, PHP & CSS
jQuery
ZPL II
Subversion
Smart Card (Mifare & MyKad)
JasperReport

These are the applications that has been developed and still being maintained everyday by us:

LIFELINE
The core application in HUSM to manage patient’s demographic information and patients appointments records and patients accounting.

LIS (Lab Information System)
A lab information system, class of software which handles receiving, processing and storing information generated by medical laboratory processes. As one of the biggest applications developed, it is being used in 13 various labs with different modules for each one, this application is also being converted from Delphi to open source Java on Linux.

E-Folder
One of the applications in the hospital that utilize the use of human input device as in Tablet PC, Touch Screen Monitors and PDA. It is still in the early phase of development.

AMS (Asset Management System)
Used mainly to keep track of items such as stationary and others. This application is used extensively by the administrative department in order to ensure better inventory management.

POLS (Pharmacy Online Prescription)
A new application that is still being tested vigorously everyday. All prescriptions will be done through computers as opposed to the old style which subsequently will be better for the management to keep track of all procedures, minimizing mistakes, controlling the amount of drugs prescribed and so on.

SPIFU & SPIFA (Sistem Pengurusan Inventori Farmasi Ubat/Alat)
Another inventory application focusing on drugs and clinical items such as syringe, glove, and others. It is used to manage the purchasing process, tracking and updating inventory information and many more.

CSSD (Central Sterile Supply Department)
Keeping track of all the in and out records of surgery items in the hospital. This application will minimize the loss of the items. The cost for this application in the market from a German company is about RM 5 millions.

Sticker
In order to get a HUSM’s sticker, every vehicle needs to be registered in this application. It is being used by the Safety Department.

FIRAS (Film Information Reject Analisyst)
An application used by the Radiology Department to keep track of the rejected x-ray films and at the same time will generate various reports including any mishandling done by the radiology staff.

ICD 10 (International Classification of Diseases Version 10)
It is a disease coding encyclopedia and is much more efficient search can be made on any disease easily. This is an offline application.

Attendance
Using 100% opensource tools, we manage to create a Mifare Card based application to record daily attendance. In the future, fingerprints will be used to identify the staff.

Transfusion
The newest application for our Blood Bank Department which is still being developed. This application will incorporate open source MyKad reading algorithm (also was built at HUSM) to cut the time for the donors to fill out the form. There’s also a portable version for mobile usage.

Mortuary
Keeps track of deceased patients in the hospital.

HUSM Formulary
Another new application for the pharmacy department that will be used as the drugs information database. At this moment, HUSM is maintaining a bigger list of drugs than the list from Ministry of Health. Pharmacist should be able to see all the information in tree view and data from its database can be used in other applications as well such as Online Prescription.

Diet Management System
Developed by our newest IT Officer, this system is used to manage all the meal’s menu for our patients. It will be used in all patient wards when it’s completed successfully.

Top 5 Subtitle Websites

amree — Tue, 07 Apr 2009 08:47:11 +0000

These are my favourite websites for movies/tvseries subtitles.

For TV Series, I recommend the first site, usually subtitle will be released on the day of the scene release, easier to see too if you want to see the latest release (just keep hitting the Reload button). For movies, use the third one, and the 6th will provide you with an automatic app to download your subtitle. If you have other good website, just post it in the commment, thanks :)
