  • Rackspace Sees OpenStack Public Cloud Demand Slowing

    The key to running a profitable cloud business for Rackspace likely doesn't rely on infrastructure but rather on support for multiple cloud infrastructures, including OpenStack.

  • Do Linux users really need more powerful computers?

    Computers just keep getting more and more powerful as the years roll by, but at what point do Linux computers jump the shark in terms of hardware specs? A writer at Foss Force questions the constant focus on ever more powerful systems.

  • Mutate 2.4 Brings Changes

    As you may know, Mutate is an open-source Linux Launcher developed in Qt 5, similar to Mac’s Alfred. Among others, it allows the users to easily search for their favorite files and applications. If the string you type does not match any file, it has an option for searching that information on Google or other search engine. Also, the launcher can be configured via the preferences menu.

  • Finally, Open-Source Model Paying Off For Red Hat

    But the Microsoft deal may have marked a watershed moment for the company, shares of which have struggled to regain past glory. The transaction sent Red Hat shares to a new high above 80 -- a level not seen since those halcyon days a decade and a half ago when it topped 150 -- and seemingly into a new era of prosperity.

  • A Closer Look At Microsoft And Red Hat Partnership

    Red Hat was conspicuous by its absence to the Azure party. Given that majority of the customers were running Red Hat Enterprise Linux (RHEL) for enterprise workloads, there was no direct migration path to Azure. Microsoft recommended CentOS and Oracle Linux – the two distributions that are highly compatible with RHEL – as alternatives. At the same time, RHEL was a first class citizen on Amazon EC2 allowing customers to bring their own license or pay by usage. Though it was possible to technically run RHEL on Azure, the customers didn’t prefer it due to lack of assurance from Red Hat. Microsoft approached Red Hat to bring RHEL to Azure, but it fell through due to the licensing and IP issues. The legal teams at both the ends could never come to a conclusion on the working model, which delayed the partnership by a few years.

  • Installing Debian – a rock solid Linux distro

    If you are looking for a solid and stable operating system for your server or desktop, look no further Debian is your choice. Interesting fact about Debian is that it usually has 3 releases stable, testing and unstable. Eventually (after many tests) the “testing” release becomes stable and the “Unstable” becomes “testing”. This way Debian ensures its users receive a well tested, stable and reliable environment.

  • An abrupt End to Debian Live

    Before even more of reality is spin-doctored into some distorted view of it, and before my past work is being discredited, I will take the high road and continue my work on Debian Live images on the outside.

  • Nvidia aims Jetson TX1 module at serious AI and robotics

    Nvidia has launched an AI and robotics oriented “Jetson TX1” module and development kit, based on an Nvidia Tegra X1 SoC running Linux.

    For its encore to the popular Jetson TK1 hacker and prototyping SBC based on the Cortex-A15 Tegra K1 SoC, Nvidia’s Jetson TX1 has moved to the 64-bit, Cortex-A57 Tegra X1 SoC. Nvidia has also split the product into separately available computer-on-module and COM/carrier development board products.

12 Best Free and Open Source OCR Tools

Optical Character Recognition (OCR) is the conversion of scanned images of handwritten, typewritten or printed text into searchable, editable documents. OCR software is able to recognise the difference between characters and images, and between characters themselves. The use of paper has been displaced from some activities. For example, the vast majority of journeys on the London Underground are made using the Oyster card without a paper ticket being issued. We have witnessed talk of a paperless office for more than 40 years. However, the office environment has shown a resistance to remove the mountain of paper generated. Things have changed in the past few years, with a marked shift in the paperless office concept. Paper documents contain a wealth of important management data and information that would be better stored electronically. There is computer software that makes this conversion possible. The benefit of scanning documents is not purely for archival reasons. OCR technology is vital for gaining access to paper-based information, as well as integrating that information in digital workflows. The selection of the right OCR tool is dependent on specific needs. For some, online OCR services may be useful, but there are privacy concerns and file size limitations. This article focuses on desktop, open source OCR software that offer good recognition accuracy and file formats. We cover OCR engines as well as front-end tools. OCR software is not mainstream so open source alternatives to proprietary heavyweight software are fairly thin on the ground. Matters are also complicated by the fact that OCR computer software needs very sophisticated algorithms to translate the image of text into accurate actual text. The software also has to cope with images that contain a lot more than text, such as layouts, images, graphics, tables, in single or multi pages. Read more

  • How to Install Apache Cassandra on Ubuntu and Other Linux - It's FOSS

  • SeaMonkey 1.1.19 compiled in EasyOS

    As I seem to have settled on Firefox as the main browser in EasyOS, I still want to keep a WYSIWYG HTML editor in the build, builtin. So, my mind turned to considering old versions of SeaMonkey... Looking at my old notes, the 1.1 series look good. Very old, version 1.1.19 was the last, released, I think, in 2010. The 1.1 series was the last, I think, that can be configured to build a standalone composer. But, then, with SM you get the browser and composer editor, both, for not much increase in size. So why not build the suite. The browser could be a substitute for the 'surfer' HTML viewer that I am currently using to view local help files in Easy.

  • How to install Proxmox? - Unixcop the Unix / Linux the admins deams

    Hello, friends. In this post, you will learn how to install Proxmox on a completely clean server. For this, then I will use a virtual machine but the procedure is simple and the same as on a real physical server. What is Proxmox? Proxmox VE “Virtual Environment” is a powerful enterprise-level virtualization platform 100% free and unlimited in its use. Of course, it has a license that allows us to obtain additional features that facilitate the administration of it. But in general, we can use it in many of our projects for free. Proxmox is essentially a Debian that adds KVM virtualization and Container-based Virtualization. Therefore the whole base is Free and this makes it possible for the final product to be free. How is it supported? The proxmox business model is based on training, certifications, and support and as I mentioned an enterprise license. One of the main advantages of Proxmox is that it has a JavaScript web interface. This has an intuitive design where all KVM clients, Linux containers, storage units, and clusters are displayed. So, let’s go for it.

This week in KDE: Fixing a bunch of annoying bugs

This was a major bug squashing week, with quite a lot of annoying issues fixed–some recent regressions, and many longstanding issues as well. On the subject of bugs and recent regressions, I’m starting to think from a higher level about how we can prevent them. KDE has largely conquered our historical issues of excessive resource consumption and visual ugliness, and our next major challenge on the path towards world domination is reliability. One idea I’m toying with is starting an initiative to focus on the “15 minute bugs”–those embarrassing issues that can easily be found within just a few minutes of using the system normally. Here is a preliminary list of these issues in Plasma. I would encourage any experienced developers to try to focus on them! The impact will be very high.

IPFire Linux Firewall Now Supports exFAT, Boosts Intrusion Prevention System’s Performance

IPFire 2.27 Core Update 161 introduces several new features, performance improvements, and some other important changes. For example, it brings support for the exFAT file system, support for the FriendlyARM NanoPI R2S open-source mini router, as well as Fast Flux Detection in the web proxy to proactively detect Fast Flux setups. Among the performance improvements included in this update, there’s a large increase of throughput for the Intrusion Prevention System (IPS), allowing it to decide if the traffic from a certain IP connection needs to be seen or not and tell the kernel to bypass it.
