How to custmize KDE’s window titlebar buttons

Filed under
Linux

If you are using the latest KDE edition of your favorite distribution, your window titlebar could be missing a button or two that you most certainly need. That is definitely the case on Sabayon 9 KDE. The titlebar could also be sporting spacers that you do not need, as is the case on Kubuntu 12.04.

KLook gets PDF/ODT support, while StackFolder gets drag-n-drop

Filed under
Linux

KLook is a multi-file-type viewer. It is not an application that can be started standalone, but is integrated into other applications, like Dolphin, KDE’s file manager. StackFolder, on the other hand, is a widget application that makes it possible to browse the contents of a directory, or your entire home folder, without opening Dolphin.

Downloads of Apache OpenOffice 3.4.0 top 5 million

If you just dropped in from outer space, Apache OpenOffice, or what used to be called OpenOffice.org, was a Sun Microsystems-sponsored project. It was at one time, the most popular office suite, as it was pre-installed on almost all Linux and BSD desktop distributions.

Mandriva 2012 technical preview

Filed under
Linux

The installer in this technical preview gives you the option to install a KDE desktop (default), a GNOME 3 desktop, LXDE and Other desktop. I hoped to show screen shots from test installations of supported desktop environments, but the GNOME 3 installation was too buggy to use. As a result, only screen shots from the KDE, LXDE and Other desktops are featured.

Linux Mint 13 MATE/Cinnamon review

Filed under
Linux

Both desktop environments aim to satisfy users who refuse to let go of old technology and those who demand new technology, but packaged in a familiar format. And Linux Mint is the first project to make both available to users in separate ISO installation images for 32- and 64-bit architectures.

This article is a review of both editions.

How to dual-boot Linux Mint 13 Cinnamon/MATE and Windows 7

Filed under
Linux

This tutorial presents a step-by-step guide on how to dual-boot either one with Windows 7 on a computer with a single hard drive. Because the Cinnamon and MATE editions of Linux Mint 13 share the same installation program, the steps involved are the same regardless of the edition you use.

2 cool features to expect in KDE 4.9

Filed under
Linux

The list of planned features is very long and includes many UX and UI additions, improvements and bugfixes, but the two that I am looking forward to the most are KLook and StackFolder, two features already available by default on ROSA Marathon 2012 and also in ROSA Desktop 2012 beta.

Filed under
Linux

To change the properties of the panel, which by default is on the bottom edge of the desktop, you need to access the Panel Tool Box widget located on the extreme right edge of the panel. Depending on the distribution you are using, the panel could be locked or unlocked.

Mageia 2 review

Filed under
Linux

The other desktop environments and window managers supported by Mageia 2 are E17, LXDE, WindowMaker and IceWM. Aside from the Live CD installation images for KDE and GNOME 3, users are offered dual-architecture CD installation images, DVD, and network-based CD ISO installation images for 32- and 64-bit architectures.

MATE vs Cinnamon

Filed under
Linux

Piwik 1.8 released

Filed under
News

It is an alternative to Google Analytics and from my experience, better in many respects. The latest version, released just today June 1 2012, is Piwik 1.8, and it comes with its share of new and improved features and bugfixes.

This release is rated critical, so if you are running Piwik 1.7.1, the previous stable version, immediate upgrade is highly recommended.

Install Cinnamon 1.4 on Fedora 17

Filed under
Linux

For those set of users, suitable alternatives are: Modify the interface with extensions, as I showed how to do here, or install Cinnamon desktop, a project from the developers of Linux Mint. Cinnamon appeals to many because it offers the familiar look and feel of the type of desktop environment they are used to.

Fedora 17 KDE and GNOME 3 preview

Filed under
Linux

Specialized Spins for Security, Scientific-KDE, Design-suite, SoaS, Games, Electronic-lab and Robotics were also released. It is very unlikely that I will review these, but there will be reviews of the main edition and KDE Spin. While the reviews are still being baked, here are a few screen shots from test installations of the main edition and KDE Spin for your viewing pleasure.

How to get back that friendly desktop look on Mageia 2 GNOME 3

Filed under
Linux

From my perspective, the worst culprit is GNOME 3. And though I have often criticised the default GNOME 3 interface, with a little bit of tweaking here and there, I have been able to get it to a point where I can actually use it for my daily computing tasks. It is not perfect, but much better than the default configuration.

Panel-Docklet: A must-install extension for GNOME 3

Consequently, I have not even bothered to install a distribution running GNOME 3 in its default state on a “production” boxen, other than for review purposes only. But while preparing a review of Mageia 2, I came across an extension that could just make me a believer and user of GNOME 3.

Linux Mint 13 MATE/Cinnamon preview

Filed under
Linux

There is Linux Mint 13 MATE, which features MATE, a desktop environment forked from GNOME 2, and Linux Mint 13 Cinnamon, which features Cinnamon, a desktop environment built atop GNOME 3. So, Linux Mint joins a growing list of Linux distributions that do not ship an edition running the GNOME 3 desktop in its default state.

  • Find the smallest number within a list with python

    In this example, we will create a python function which will take in a list of numbers and then return the smallest value. The solution to this problem is first to create a place holder for the first number within the list, then compares that number with other numbers within the same list in the loop. If the program found a number which is smaller than the one in the place holder, then the smaller number will be assigned to that place holder.

  • Basic Input, Output, and String Formatting in Python

    To be useful, a program usually needs to communicate with the outside world by obtaining input data from the user and displaying result data back to the user. This tutorial will introduce you to Python input and output. Input may come directly from the user via the keyboard, or from some external source like a file or database. Output can be displayed directly to the console or IDE, to the screen via a Graphical User Interface (GUI), or again to an external source.

  • Want to level up your Python? Join Weekly Python Exercise, starting July 2nd

    Let’s face it: Stack Overflow has made developers’ lives easier. Almost every time I have a question, I find that someone on Stack Overflow has asked it, and that people have answered it, often in great detail. I’m thus not against Stack Overflow, not by a long shot. But I have found that many Python developers visit there 10 or even 20 times a day, to find answers (and even code) that they can use to solve their problems.

  • Introducing pytest-elk-reporter

    Few years back I’ve wrote a post about how I’ve connected python based test to ELK setup - “ELK is fun”, it was using an xunit xml, parsing it and sending it via Logstash. Over time I’ve learn a lot about ElasticSearch and it’s friend Kibana, using them as a tool to handle logs. and also as a backend for a search component on my previous job. So now I know logstash isn’t needed for reporting test result, posting straight into elasticsearch is easier and gives you better control, ES is doing anything “automagiclly” anyhow nowadays.

  • OpenStack Stein feature highlights: vGPU support coming in Red Hat OpenStack Platform 15

    Red Hat is working on the next release of the supported enterprise distribution of OpenStack, Red Hat OpenStack Platform 15, based on the Stein community release. In this multi-part blog series, we’ll be examining some of the features that Red Hat and the open source community have collaborated on–starting with a look to future workloads, such as artificial intelligence. "How does OpenStack enable next generation workloads?" you ask. When it comes to computer-driven decision making, machine learning algorithms can provide adaptable services that can get better over time. Some of these workloads, such as facial recognition, require GPUs to ingest and process graphical data in real time. But the more powerful GPUs often used for machine learning and such are expensive, power-hungry, and can take up a lot of room in the servers' chassis. When working with GPUs at scale, optimized utilization is key to more cost effective machine learning.

  • Panfrost Gallium3D Picks Up Yet More Features Thanks To Collabora's Summer Internship

There's yet another batch of new features and improvements to talk about. Most of this feature work continues to be done by Panfrost lead developer Alyssa Rosenzweig who is interning at Collabora this summer and appears to be spending most of her time working on this reverse-engineered Arm graphics driver supporting their recent generations of IP.

  • Vulkan 1.1.112 Released While Open-Source ANV + RADV Drivers Continue Marching Along

    Vulkan 1.1.112 was outed this morning as the newest documentation update to this high performance graphics and compute API. Vulkan 1.1.112 is quite a mundane update with just documentation corrections and clarifications this go around and not any new extensions. But at least the clarifications should help out some and other maintenance items addressed by this Vulkan 1.1.112 release. It's not a surprise the release is so small considering Vulkan 1.1.111 was issued just two weeks ago.
