Adding a Simple GUI to shell scripts with kdialog

Wednesday 30th of November 2016 10:09:46 PM
Shell scripts are incredibly useful things. They allow you to do something as basic as creating an easy command to replace a more difficult one with lots of flags, to batching up many complex commands to run from a cron job. They’re great because you can quickly fire them off in your favorite terminal, but in some cases they require you to remember specific combinations of flags or options. If you find yourself in this situation, you can add some simple GUI dialogs to help you speed your way through the task at hand.

Open source dependency management is a balancing act

Wednesday 30th of November 2016 04:35:40 PM
During my career I have spent a lot of time packaging other people's code, writing my own, and working on large software frameworks. I have seen projects that still haven't released a stable version, never quite hitting 1.0, while others made 1.0 releases within months of beginning development, and then quickly moving on to 2.0, 3.0, etc. There is quite a variance in these release cycles, and this coupled with maintaining large projects can make things difficult.read more

4MLinux 20.1 released.

This is a minor maintenance release in the 4MLinux STABLE channel. The release ships with the Linux kernel 4.4.34, which restores PAE support that "magically" disappeared in 4MLinux 20.0 (sorry :-). Additionally, some popular programs (Double Commander, Dropbox, Firefox, Java RE, Opera, PeaZip, Thunderbird, Wine) have been updated, too. Read more

Refracta 8.0 Is a Pint-Sized Powerhouse

Refracta is a somewhat obscure Linux distribution that offers exceptional functionality and stability. Obscurity is not always a bad thing when it comes to Linux distros. You can find some very worthwhile alternatives to your current operating system. Refracta is a big surprise in a small package. Many look-alike desktop distros are difficult to distinguish from run-of-the-mill garden varieties. Others offer new adopters something unique that makes using them fun and productive. Refracta is one of the few full-service Linux distros that makes an easy and more convenient replacement for pocket Linux options such as Puppy Linux. Not all Linux distros that install to a USB drive -- and have the ability to save files and system settings in a persistent mode -- work equally well. Read more

Clear Linux With Mesa 13 Is A Strong Match For Intel Linux Performance

When benchmarking Intel's Clear Linux distribution earlier this year we found its Intel graphics performance to be quite good and slightly faster than other Linux distributions even when Clear was using an older version of Mesa. Now with Clear Linux having switched to Mesa 13, I decided to run some fresh Intel OpenGL benchmarks on it compared to other distributions. Read more

PTS: PHP 7.1 vs. PHP 7.0 vs. HHVM Benchmarks

With today's PHP 7.1 release, performance isn't highlighted as much as language improvements to this first major update to PHP7, but I decided to run some PHP 7.1, PHP 7.0, PHP 5.6, PHP 5.5, and HHVM benchmarks of our open-source Phoronix Test Suite code-base. These self-tests of the Phoronix Test Suite aren't the conventional PHP workload of just a CMS, blog, or other web application that can be cached, etc, but effectively of a PHP CLI application. So keep this in mind when looking at the results and that your mileage may vary depending upon use-case. Read more
