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.

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.

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.

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.

KVM and Xen Project: Commercial Exploitation and Unikraft Work

  • Cloud, Linux vendors cash in on KVM-based virtualization

    Vendors such as Red Hat, IBM, Canonical and Google rely on KVM-based virtualization technology for many of their virtualization products because it enables IT administrators to execute multiple OSes on the same hardware. As a result, it has become a staple in IT admins' virtual systems. KVM was first announced in October 2006 and was added to the mainline Linux kernel in February 2007, which means that if admins are running a Linux machine, they can run KVM out of the box. KVM is a Type 1 hypervisor, which means that each individual VM acts similar to a regular Linux process and allocates resources accordingly. Other Type 1 hypervisors include Citrix XenServer, Microsoft Hyper-V, Oracle VM Server for x86 and VMware ESXi.

Gopher: When Adversarial Interoperability Burrowed Under the Gatekeepers' Fortresses

In the early 1990s, personal computers did not arrive in an "Internet-ready" state. Before students could connect their systems to UMN's network, they needed to install basic networking software that allowed their computers to communicate over TCP/IP, as well as dial-up software for protocols like PPP or SLIP. Some computers needed network cards or modems, and their associated drivers. That was just for starters. Once the students' systems were ready to connect to the Internet, they still needed the basic tools for accessing distant servers: FTP software, a Usenet reader, a terminal emulator, and an email client, all crammed onto a floppy disk (or two). The task of marshalling, distributing, and supporting these tools fell to the university's Microcomputer Center. For the university, the need to get students these basic tools was a blessing and a curse. It was labor-intensive work, sure, but it also meant that the Microcomputer Center could ensure that the students' newly Internet-ready computers were also configured to access the campus network and its resources, saving the Microcomputer Center thousands of hours talking students through the configuration process. It also meant that the Microcomputer Center could act like a mini App Store, starting students out on their online journeys with a curated collection of up-to-date, reliable tools. That's where Gopher comes in. While the campus mainframe administrators had plans to selectively connect their systems to the Internet through specialized software, the Microcomputer Center had different ideas. Years before the public had heard of the World Wide Web, the Gopher team sought to fill the same niche, by connecting disparate systems to the Internet and making them available to those with little-to-no technical expertise—with or without the cooperation of the systems they were connecting. Gopher used text-based menus to navigate "Gopherspace" (all the world's public Gopher servers). The Microcomputer Center team created Gopher clients that ran on Macs, DOS, and in Unix-based terminals. The original Gopher servers were a motley assortment of used Macintosh IIci systems running A/UX, Apple's flavor of Unix. The team also had access to several NeXT workstations.

  • Network Automation: Why organizations shouldn’t wait to get started

    For many enterprises, we don’t need to sing the praises of IT automation - they already get it. They understand the value of automation, have invested in a platform and strategy, and have seen first-hand the benefits IT automation can deliver. However, unlike IT automation, according to a new report from Forrester Research 1, network automation is still new territory for many organizations. The report, "Jump-Start Your Network Automation," found that 56% of global infrastructure technology decision makers have implemented/are implementing or are expanding/upgrading their implementation of automation software, while another 19% plan to implement it over the next 12 months. But those same organizations that are embracing IT automation haven’t necessarily been able to take that same initiative when it comes to automating their networks. Even if they know it will be beneficial to them, the report found that organizations often struggle with even the most basic questions around automating their networks.

  • Using a story’s theme to inform the filmmaking: Farming for the Future

    The future of farming belongs to us all. At least that’s the message I got from researching Red Hat’s most recent Open Source Stories documentary, Farming for the Future. As a self-proclaimed city boy, I was intrigued by my assignment as director of the short documentary, but also felt like the subject matter was worlds away. If it did, in fact, belong to all of us how would we convey this to a general audience? How could we use the film’s theme to inform how we might approach the filmmaking to enhance the storytelling?

  • Introduction to open data sets and the importance of metadata

    More data is becoming freely available through initiatives such as institutions and research publications requiring that data sets be freely available along with the publications that refer to them. For example, Nature magazine instituted a policy for authors to declare how the data behind their published research can be accessed by interested readers. To make it easier for tools to find out what’s in a data set, authors, researchers, and suppliers of data sets are being encouraged to add metadata to their data sets. There are various forms for metadata that data sets use. For example, the US Government data.gov site uses the standard DCAT-US Schema v1.1 whereas the Google Dataset Search tool relies mostly on schema.org tagging. However, many data sets have no metadata at all. That’s why you won’t find all open data sets through search, and you need to go to known portals and explore if portals exist in the region, city, or topic of your interest. If you are deeply curious about metadata, you can see the alignment between DCAT and schema.org in the DCAT specification dated February 2020. The data sets themselves come in various forms for download, such as CSV, JSON, GeoJSON, and .zip. Sometimes data sets can be accessed through APIs. Another way that data sets are becoming available is through government initiatives to make data available. In the US, data.gov has more than 250,000 data sets available for developers to use. A similar initiative in India, data.gov.in, has more than 350,000 resources available. Companies like IBM sometimes provide access to data, like weather data, or give tips on how to process freely available data. For example, an introduction to NOAA weather data for JFK Airport is used to train the open source Model Asset eXchange Weather Forecaster (you can see the model artifacts on GitHub). When developing a prototype or training a model during a hackathon, it’s great to have access to relevant data to make your solution more convincing. There are many public data sets available to get you started. I’ll go over some of the ways to find them and provide access considerations. Note that some of the data sets might require some pre-processing before they can be used, for example, to handle missing data, but for a hackathon, they are often good enough.
