Creating An NFS-Like Standalone Storage Server With GlusterFS On CentOS 5.4

Filed under
HowTos

This tutorial shows how to set up a standalone storage server on CentOS 5.4. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

Build Your Own Video Community With Lighttpd And FlowPlayer (Ubuntu 9.10)

Filed under
Ubuntu
HowTos

This article shows how you can build your own video community using lighttpd with its mod_flv_streaming module (for streaming .flv videos, the format used by most major video communities such as YouTube) and its mod_secdownload module (for preventing hotlinking of the videos) on Ubuntu 9.10. I will use FlowPlayer as the video player, a free Flash video player with support for lighttpd's mod_flv_streaming module. I will also show how you can encode videos (.mp4 .mov .mpg .3gp .mpeg .wmv .avi) to the FLV format supported by Adobe Flash.

Docky: Another OS X-like Doc

Filed under
Software
HowTos

ghacks.net: OS X users love their Dock..and with good reason. Not only is it a handy way to launch applications, it’s also rather stylish. I have covered a tool that had a similar look and feel before and although that tool served it’s purpose well, at times it could be a bit buggy. Docky is a little bit different.

Ryzen Compiler Performance: Clang 4/5 vs. GCC 6/7/8 Benchmarks

A few days back I posted some fresh AMD Ryzen compiler benchmarks of LLVM Clang now that it has its new Znver1 scheduler model, which helps out the performance of Ryzen on Linux with some of the generated binaries tested. But it was found still that Haswell-tuned binaries are sometimes still faster on Ryzen than the Zen "znver1" tuning itself. For continuing our fresh compiler benchmarks from AMD's new Ryzen platform, here are the latest GCC numbers. Read more

More Security Leftovers

  • How the Swedish administration leaked EU’s secure STESTA intranet to Russia, then tried glossing over it

    The Swedish administration is leaking its secret intranet and databases to Russia, via its Transport Agency, via the IBM cloud, via IBM's subcontractor NCR (formerly AT&T) in Serbia, which is a close Russian military ally. Giving staff in Serbia administrative access to these networks practically guarantees that Russia also has access to the network. The European Union's secure STESTA network is also connected to the leaked intranet. But this is not about geopolitics and who’s allied with whom, but about how an administration tries to quiet down and gloss over an apocalyptically stupid and monstrously damaging data leak.

  • Outsourcing Nightmare

  • Status update from the Reproducible Builds project
    Since then, we have made considerable progress which has been reported during DebConf 15 and 16 talks as well as other conferences around the world. However, for the sake of information preservation and clear communication we felt the need to write a newer report here.

KDE: KDE Slimbook, Akademy, and GSoC

  • Yesterday I picked up my new KDE Slimbook from the Slimbook.es stand at Akademy.
    First thing I did, of course, was boot it with my FreeBSD 11.0 SD card, to see if it works with my favorite operating system (with Plasma 5 desktop, of course). Nope: 11.0 hangs after finding acpi_ec0, so I will write about that later this week. Second thing I did was boot KDE Neon (pre-installed) on it, to see how it works out-of-the-box. I collected a bunch of tiny-little-irritations, papercuts if you will, from the basic installation — which have disappeared after an update and reboot.
  • Akademy 2017 -- Day 1
    During the first day at the Akademy, everything went according to plan and nearly everything was on time. Kudos to the organisers. The weather was balmy at the beginning of the day and, although Aleix Pol said it was not hotter than a hot day in Barcelona, many of the Scandinavian and Scottish attendees were visibly wilting under the sun. Fortunately for them, the venue is equipped with air-conditioning. Little known fact about Almería: it is situated in the biggest desert in Europe, the Desert of Tabernas. A better known fact is that that same desert has been used as a location for many spaghetti westerns, including the seminal Sergio Leone movies "For A Fistful of Dollars" and "The Good, the Bad and the Ugly". What is more interesting for some KDE members is that Tabernas has also been used in the filming of at least one Doctor Who episode ("A Town Called Mercy"). Unsurprisingly, the whovians amongst us quickly got busy and organised a trip to the place of the shoot for later in the week.
  • Akademy-es 2017 Fue Muy Bien
    On the 20th and 21st of July, KDE España held, with the invaluable help of UNIA, HackLab Almería and the University of Almería, and with the sponsorship of Opentia, its 12th annual gathering: Akademy-es 2017. As it always happens when Akademy takes place in Spain, Akademy-es 2017 became a prelude of the international event and many well-known KDE developers attended. Throughout two days, talks were offered covering many different topics, including Plasma, programming (C++, Qt, mobile), exciting projects like Kirigami, proposals for the future such as KDE on automobile, encouragement to use KDE software and contribute to KDE, and information about KDE España.
  • GSoC’17-Week #5
    In Krita, we cannot delete the bundle created just like that. The Bundles created are saved as the KisResource in a QList. We have to remove it from that list, then obviously, we have to remove it from the list widget where this bundle is shown. Then we have to BlackList the file. Then from there, we can remove the blacklisted bundles as we empty a recycle bin ;).
