Not a catchy name…

Not really welcoming... for people who understand French.

Arbitrage Program

This is a demonstration of my Arbitrage Program:

This program is checking if there is an arbitrage opportunity.
Based on two different betting websites, it calculates if there is a "sure bet" or not.
There is a sure bet if the sure bet number is inferior to 1.

You just need to select the competition (only 3 competitions implemented so far, but adding competitions is not a big deal) and SCAN!
The results is then displayed to you.

An evolution of the software would be to check every X seconds and actually really automatically bet on the websites if a sure bet is found.
But this is dealing with real money and probably illegal so my tool is only a simulation tool!

Software developed with Qt/C++.
Binaries are available on Windows and Linux (require additional installation of OpenSSL and Visual C++ redistributables on Windows, if you do not have them).

x264, FFMpeg, wxWidgets et Aegisub RPMs pour Fedora 13

Aegisub is a powerful subtitle editor.
However, there is no official deb or rpm to install it easily on Debian and Red Hat based OS so we have to install it from the sources.

Many people have problems installing from the sources and getting everything to work as they want.
I recently compiled a working version of Aegisub on Linux Fedora Core 13 x86_64 and wanted to share the generated rpm.

This version is meant to work with a custom version of x264 and ffmpeg (built on today's snapshot, Aug. 22nd 2010) that decodes/encodes a wide range of audio and video codecs, including both free and non-free codecs.

The configure used during the compilation of ffmpeg and the codecs available from this build are shown here: ffmpeg-formats.txt
As you can see, this build is able to en/decode most of the video/audio formats.

To install Aegisub with this build of ffmpeg (and x264), just install the following rpms from the web browser:
x264-0.27-1.fc13.x86_64.rpm
libnut-0.0.0-1_r661.fc13.x86_64.rpm
ffmpeg-0.6-3.fc13.x86_64.rpm
wxWidgets-2.9.0-1.fc13.x86_64.rpm
aegisub-2.1.8-4749.fc13.x86_64.rpm

Or with these command lines (as root or sudo):

su -
wget http://rpms.dallagnese.fr/x264-0.27-1.fc13.x86_64.rpm \
     http://rpms.dallagnese.fr/libnut-0.0.0-1_r661.fc13.x86_64.rpm \
     http://rpms.dallagnese.fr/ffmpeg-0.6-3.fc13.x86_64.rpm \
     http://rpms.dallagnese.fr/wxWidgets-2.9.0-1.fc13.x86_64.rpm \
     http://rpms.dallagnese.fr/aegisub-2.1.8-4749.fc13.x86_64.rpm \

yum -y install --nogpgcheck x264-0.27-1.fc13.x86_64.rpm \
               libnut-0.0.0-1_r661.fc13.x86_64.rpm \
               ffmpeg-0.6-3.fc13.x86_64.rpm \
               wxWidgets-2.9.0-1.fc13.x86_64.rpm \
               aegisub-2.1.8-4749.fc13.x86_64.rpm

If you want more details about these packages, you can check the packages installations step by step:

1. x264

Directly from the web browser: x264-0.27-1.fc13.x86_64.rpm

Or through command lines (as root or sudo):

wget http://rpms.dallagnese.fr/x264-0.27-1.fc13.x86_64.rpm
yum -y install --nogpgcheck x264-0.27-1.fc13.x86_64.rpm

2. FFMpeg

Directly from the web browser:
libnut-0.0.0-1_r661.fc13.x86_64.rpm (required by this ffmpeg build)
ffmpeg-0.6-3.fc13.x86_64.rpm

Or through command lines (as root or sudo):

wget http://rpms.dallagnese.fr/ffmpeg-0.6-3.fc13.x86_64.rpm \
     http://rpms.dallagnese.fr/libnut-0.0.0-1_r661.fc13.x86_64.rpm \

yum -y install --nogpgcheck ffmpeg-0.6-3.fc13.x86_64.rpm \
               libnut-0.0.0-1_r661.fc13.x86_64.rpm

3. wxWidgets

Before installing Aegisub, we need to install a recent version of wxWidgets.
Aegisub final version 2.1.8 (rev 4749) works only with wxWidgets 2.9+ and the last officially supported version of wxWidgets on Fedora is (as today) is 2.8.11.

Directly from the web browser: wxWidgets-2.9.0-1.fc13.x86_64.rpm

Or through command lines (as root or sudo):

wget http://rpms.dallagnese.fr/wxWidgets-2.9.0-1.fc13.x86_64.rpm
yum -y install --nogpgcheck wxWidgets-2.9.0-1.fc13.x86_64.rpm

Now it's time to install Aegisub!

4 Aegisub

Directly from the web browser: aegisub-2.1.8-4749.fc13.x86_64.rpm

Or through command lines (as root or sudo):

wget http://rpms.dallagnese.fr/aegisub-2.1.8-4749.fc13.x86_64.rpm
yum -y install --nogpgcheck aegisub-2.1.8-4749.fc13.x86_64.rpm

N.B.:

This is my first time making RPMs from my compilations, so this is not guaranteed to work!
If you try, please give me some feedback on how it works.

And please give me any comments, suggestions or critics you have!

Watch copy-protected DVD on Fedora 13

Even though you installed the last version of VideoLAN VLC, it may happen that you are not able to read DVDs that have a copy protection.

The trick to get this to work is to install the libdvdcss library (which is not in the official repositories).
You can find this library on the ATrpms.

To install the library:

wget http://dl.atrpms.net/all/libdvdcss2-1.2.10-5.fc13.x86_64.rpm http://dl.atrpms.net/all/libdvdcss-1.2.10-5.fc13.x86_64.rpm
yum install libdvdcss-1.2.10-5.fc13.x86_64.rpm \
            libdvdcss2-1.2.10-5.fc13.x86_64.rpm

Enjoy!

Hi-tech sushi

Are you afraid not to be able to order your favourite sushis at the local restaurant?
No fear anymore, the hi-tech sushi are here to serve you! (and to kill waiters and waitresses...)

Sushi Ordering Panel

You just need to tap on the sushi you want...
and the orders arrive directly to the Chef's monitor:

The Chef just has to read on his monitor

The Chef receives who (which seat number) ordered what and can prepare it.
No waiting time, no noisy environment to disturb you to order your sushi, everything is machinized...

For now, the Chef is still here cooking sushi in front of us...
But for how long? When will the machine also cook and serve us directly? ......

PS : Restaurant in Yokohama.
