    Typesetting equations in your blog

    Typesetting equations in a website is not always an easy task, and it would be wonderful to have the power of LaTeX available. Well, if you use WordPress to manage your blog, that’s possible, and all it takes is installing the wp-latex plugin. WordPress offers a public LaTeX server, where your equations will be generated and converted into images in the displayed web page, however, if you have a LaTeX server on your host you can use it in place of the public server. Example? Let’s write a kinetic equation: As you might have noticed from the presence of special fonts, support for AMS packages is provided automatically, without any…

    Some comment on openSUSE 11.3

    OpenSUSE 11.3 has just been released, after eight months of development. It follows openSUSE 11.2, one of the best openSUSE releases of the last years, at least in my opinion. Unfortunately openSUSE 11.3 does not seem to be at the same level. It still is a good core release, but it is not as clean as openSUSE users are used to. First of all, it seems the release was rushed again, without preparing the last very important details: there are no official repositories for accelerated video drivers, a problem that affected also other releases in the past, disappointing users, especially the new and inexperienced ones. Someone claims this is not…

    Installing OpenFOAM 1.7 on openSUSE 11.3

    The installations instructions for OpenFOAM 1.7.0 on openSUSE 11.3 are almost identical to those for openSUSE 11.2 reported here. However, one additional package is necessary. For the reader’s convenience, I report the whole procedure, highlighting in orange the differences with the installation on openSUSE 11.2. The steps of the procedure are the following: Use YaST to install the C/C++ development pattern in YaST cmake libqt4-devel (required to build paraview) libQtWebKit-devel (required to build paraview) flex Create a directory called OpenFOAM in your home directory mkdir ~/OpenFOAM Enter the OpenFOAM directory cd ~/OpenFOAM Download both the OpenFOAM and ThirdParty packages from here and save them in your ~/OpenFOAM directory Extract the OpenFOAM-1.7.0.gtgz…

    Installing OpenFOAM 1.7 on openSUSE 11.2

    Installing OpenFOAM® 1.7 on openSUSE 11.2 is very similar to installing OpenFOAM 1.6.x, however some differences deserve to be noticed. The steps of the procedure are the following: Use YaST to install the C/C++ development pattern in YaST cmake libqt4-devel (required to build paraview) flex Create a directory called OpenFOAM in your home directory mkdir ~/OpenFOAM Enter the OpenFOAM directory cd ~/OpenFOAM Download both the OpenFOAM and ThirdParty packages from here and save them in your ~/OpenFOAM directory Extract the OpenFOAM-1.7.0.gtgz package with the command: tar xzf OpenFOAM-1.7.0.gtgz Extract the ThirdParty-1.7.0.gtgz package with the command: tar xzf ThirdParty-1.7.0.gtgz Open your ~/.bashrc file in a text editor and add the line: .…

    OpenFOAM 1.7 released

    OpenCFD® released OpenFOAM® 1.7, which consolidates the features of the git version OpenFOAM 1.6.x in the new release, under the GNU GPL 3 license. A summary of the new features can be found here, while more details are available in the release notes of the code. The new version can be downloaded from the web-page at this link. Differently from the previous releases, OpenFOAM 1.7 is distributed in binary form only for Debian/Ubuntu systems, while for other Linux distributions only the source code is available. No pre-compiled, platform-independent binary package is made available. As usual, however, the code has been tested on the latest stable releases of openSUSE and Ubuntu,…

    Installing Skype on openSUSE 11.3 – 64 bit

    The openSUSE project is going to release openSUSE 11.3 very soon, and, as usual, some additional work is necessary to make Skype work on the 64 bit version, since the original package for openSUSE 11+ is compiled only for 32-bit systems. These instructions are not necessary on 32-bit systems. Before installing the Skype RPM you find on Skype website, you have to install the following packages, if not already present on your system: libasound2-32bit xorg-x11-libXv-32bit xorg-x11-libs-32bit libqt4-32bit libqt4-x11-32bit libpng12-0-32bit These packages were not installed by default on my system after performing a clean installation of openSUSE 11.3 from the KDE live-CD. It is possible they are already present in other…

    Some updates…

    May has been quite a busy month, traveling around US for meetings and conferences: On May 4 – 6, I’ve been at the NETL 2010 Workshop on Multiphase Flow Science where I gave a talk on the progress made with quadrature-based moment methods for gas-particle flows in Prof. Fox research group. On May 24 – 26, I’ve been at a very interesting conference on Computational and Mathematical Methods in Science and Engineering, in the Mathematics Department of the University of Wisconsin – Madison, where I’ve been kindly invited by Prof. Shi Jin to give a talk on quadrature-based moment methods for gas-particle flows. On May 31 – June 4 I’ve…
