EXE-files accidentally associated with an application

It is nearly impossible to associate a Windows EXE file to a normal application. The context command “Open with …” is not available for this file type.

But broken EXE-files or wrong commands in desktop shortcuts can ask for a application to start with. When your fingers are faster than your brain you cannot start EXE files anymore because Windows try to open them with the application selected before.

Unfortunately you cannot start any repair tools or even the registry editor to fix the problem manually now.

This how-to describes in a few steps how to bring your computer back working correctly.

Zemanta’s Related Posts migration to qTranslate-Plus

The Zemanta’s Related Posts WordPress Plug-in works very well  with qTranslate. But it does not with qTranslate-Plus. Since the original qTranslate is deprecated many blogger have to switch to qTranslate-Plus. Plug-ins which works well with the original plug-in does not with the successor. The reason is the prefix of qTranslate-Plus functions in comparison to the original qTranslate. I described this in my post qTranslate-Plus Migration.

You just have to find the appropriate files which contain the qTranslate function calls. But a lot of plug-ins contain a lot of files. So it is hard to find the files in question. Zemanta’s Related Posts plug-in is such an example.

qTranslate-Plus migration

People who use qTranslate as their multi-language plug-in for WordPress run into trouble for a while. The Developer Qian Qin does not seem to work on the plug-in anymore. The last version is not compatible with the WordPress version 3.8.2 or higher. Fortunately Mirko Papa Salvatore from Prima Pagina in Italy forked qTranslate and provides qTranslate Plus.

So it is self-evident to migrate to qTranslate-Plus rather than WPML. Unfortunately the migration is not as easy as expected. This How-To describes the migration of a multi-language WordPress (WP) blog from qTranslate (qT) to qTranslate-Plus (qT+). Continue reading qTranslate-Plus migration

inotify_add_watch failed in Octave’s GUI

Version 3.8 of Octave has an unofficial and experimental GUI similar to Matlab. But on my Linux Mint 17 (Quiana), based on Ubuntu 14.04 (Trusty Tahir), I got a warning:

QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: No space left on device. It does not appear in the console mode. I send a bug report and got a prompt fix. Thanks to Mike Miller of the Octave team for assistance and the fix. It was a system configuration issue and not really the fault of Octaves’s developers.

Find the fix below. It should work in Ubuntu 14.04 and in other distributions based on Ubuntu, too. Continue reading inotify_add_watch failed in Octave’s GUI

Install DISLIN on Ubuntu

DISLIN is a very nice and well-documented 2-D and 3-D plotting framework for Fortran and some other programming languages. Furthermore DISLIN provides some widgets to create simple graphic user interfaces (GUIs). This how-to describes how to install DISLIN on an arbitrary Ubuntu system and how to compile and link a sample Fortran 90  program with the shared and static libraries.

Since Ubuntu 12.04 (Precise Pangolin) and DISLIN 10.2 came out, things are easier for Debian-based Systems now. However 64-bit users have to consider some points.

I updated this article for Ubuntu 14.04 (Trusty Tahr) and DISLIN 10.4 users. Obsolete instructions for Ubuntu 12.04 and lower as well as DISLIN 10.0 were crossed.
