WARNING: All the Cinterion related content from this blog will be removed to go to the javacint wiki soon. Please get used to going there. Update anything Cinterion gives specifications on how to send SMS messages to launch a remote Over The Air Provisionning (OTAP) operation. Recently, someone asked me : We have a little program on some TC65 chips that only send SMS, we would like to connect it to the software that you built. What would we have to do. Well that where the magic comes. You don’t have to touch any of the hardware. The only concrete thing you might have to do is enable GPRS on the sim cards of your M2M fleet. ...

WARNING: All the Cinterion related content from this blog will be removed to go to the javacint wiki soon. Please get used to going there. M2M projects are the type of project I like to work on. Connecting remote devices, making them work together, and controlling everything remotely are things i love ! I discovered the Cinterion TC65 (which belonged to Siemens then) 3 years ago. And it was a dream come true. I’ve been mostly working on it to build some powerfull GPS tracking software over GPRS. But I have also worked on some other projects making it communicate with some equipments using GPIO or serial port. ...

Settings a master-master synchronization is pretty easy. You can find a quick guide to do this on google, just try. What is a little bit more problematic is when you lose your loved sync. And that can happen. It happened to me yesterday, I upgraded my two servers from Debian 4.0 to Debian 5.0. The reason is that the old version (something like 5.0.32) used the Relay_Log_File ${hostname}-relay-bin.XXXXXX. And the new version (5.0.51a-24-log) decided to use mysqld-relay-bin.XXXXXX. ...

Mono enables you to run .Net program on almost every operating systems and my second favorite one is Debian/Linux (my first one is Windows as you can guess). You need to get some tools: apt-get install subversion make automake autoconf python gcc g++ libtool pkg-config bison libxml-perl gawk Get the SVN repository (very slow): mkdir ~/mono cd ~/mono svn co svn://anonsvn.mono-project.com/source/trunk/mcs svn co svn://anonsvn.mono-project.com/source/trunk/mono svn co svn://anonsvn.mono-project.com/source/trunk/libgdiplus #svn co svn://anonsvn.mono-project.com/source/trunk/gtk-sharp If you don’t have any mono on the system: ...

This is a little program I made some time ago because I had some problems with some log files I generated. I didn’t know how big they would end up and I had a limited disk space. As you can guess, it can be used for any files. So I could have called it “DOF * Delete Oldest Files”. The idea of this tiny .Net program is to delete the oldest logs first. It scans every files and delete as many files as required to reach its objectives. ...

I recently had to clean a huge (113 000 rows) document library. The first question that must come in mind is : Why was it so big ? Well, someone thought it was beter to store data in lots of XML files instead of in a classic list. The second question is: How ? First, you have to understand that you can’t use a DeleteAll() method, it doesn’t exist. You must fetch data by little packet of rows. If you try to get everything, you will have a OutOfMemoryException. ...

When starting with SharePoint development, a common question is “Which objects should I dispose?”. This is crucial because SharePoint leaks approximately 1 MB of memory per undisposed IDisposable object. For components like menus, this can quickly add up to 10 MB per page load. While the MSDN documentation provides comprehensive guidance, here’s the quick answer: In your WebPart, dispose of all SPWeb and SPSite objects except: SPContext.Current.Site SPContext.Current.Web SPContext.Current.Site.RootWeb For Features, dispose of all SPWeb and SPSite objects except those provided in your “properties” variable. ...

I edited this page on the 21 March 2010 because a lot of people seem interested and the code as since improved ! PHP has a pretty interesting feature, you can define a callback method to “catch” any error “thrown” in your code. And I’m sure most of you don’t use it. It’s really usefull when you want to make sure to detect error before any user reports it (which can takes time). This is all about avoiding to demolish with some lame errors your “user experience”. ...

Software version number is quite important. It helps you track what versions have your users when they report something. And when it’s linked to an SVN version number, it’s even better. Well, with MSBuild Community Task, you can easily automatically generate smart version numbers, you have to: Download MSBuildCommunityTasks Make sure your “svn.exe” binary is in C:\program files\subversion\bin Add this at the end of your .csproject file : 2011-07-02 update: As given in Markus comment, this code is a much better option: ...

I’ve decided to start writing about my technical work and projects in English. While I’m comfortable reading English, I want to improve my writing skills.
