New HTPC the Lenovo Ideastation Q190 & Ubuntu

We cut the cord a couple of years ago, the need to get TV over traditional TV Ariel was no longer needed and services such as TV Catchup, iPlayer and the other UK Catchup TV Channels streamed over the net to my TV were all we needed.

Having had an Asrock 330 Ion be the trusty device for nearly 5 years the box finally gave up the shost last week.

The options available for using the internet to provide your TV are huge, from the giants of Apple with Apple TV, Google are dipping their toes in the water they have the ChromeCast, and there are a huge bagfull of Android Devices which all claim to plug into the HDMI port of your TV.. Then there is the Raspberry PI which has a custom build of OS's to provide different interfaces.

While I know this is a Linux site, i feel that Windows RT is getting the same bad rap Linux gets from the Tech press in many areas. A lack of true understanding of just what they are dealing with or just a huge need to present some form of being part of the crowd. I'm not sure just what it is however it needs to change. It's the same thing that happens when some people review Ubuntu PHone for example and claim it's not a viable platform.. and it annoys me..

Fixing OpenSuse’s Dog Awful default fonts…

Filed under
Howtos

Lets not beat around the bush here, the default font rendering in OpenSuse and the default font do not an OS fit for reading make.. this can be fixed however..

Love or hate Ubuntu, out of the box it has one of the best font rendering setups of any distro and considering how much time we spend on our PC’s setting your fonts up correctly is one less headach, literally.

I’m not sure how much of these instructions I got right, however after a reboot the screen text does at least look better..

Linux Desktops KDE 4 vs Unity vs Gnome 3 in the real world.

If you’ve chosen one of the major Linux distributions chances are (unless you’re a Mint user) you’ve come across the three big Linux Gui’s KDE, Gnome 3 and Unity.

The problem with any post like this is it’s an opinion piece, and with out a shadow of a doubt my opinion is probably going to vastly different to a lot of people out there. Linux users can be ferociously protective of not just their choice of distro, but their choice of Desktop as well.

Is OpenSuse a viable Ubuntu alternative?

Filed under
Linux

There’s lots of forums and even 3 or 4 releases in I still hear people talking about how much they dislike Unity, which is a shame because it’s turning into quite a nice Gui from where i’m sitting, however one thing Linux has is choice. If nothing else there are other solid, stable distributions out there which offer a user a good solid alternative. Once such example is maybe OpenSUSE.

OSS: Apache Cassandra, Jib,WSO2 and More

  • Apache Cassandra at 10: Making a community believe in NoSQL
    Ten years ago this month, when Lehman Brothers was still just about in business and the term NoSQL wasn't even widely known, let alone an irritant, Facebook engineers open-sourced a distributed database system named Cassandra. Back then, the idea that huge numbers of companies would need a scalable database was almost laughable – and that grip of traditional relational database systems is reflected in the mythical moniker given to what would become one of the first of many databases designed to run on a cluster of machines. Named after the Greek figure who was cursed to utter the truth but was never believed, Cassandra might seem an odd choice for a system whose raison d'être is believability – but it delivered a nice dig at the stalwarts of the RDBMS world… and their trust in a false Oracle.
  • Google Launches Jib, Automated Container Packaging for Java Apps
    Google has released software that could automate the packaging of a Java program so that it can be run in the cloud-native environment. Jib is an open-source Java “containerizer,” one that handles all the steps of packaging your application into a container image, according to Appu Goundan and Qingyang Chen, two Google engineers who co-wrote a blog post announcing the new technology. Created over two decades ago at Sun Microsystems, Java was introduced as a “write once, run anywhere” programming language, where all the code would be packaged in a JAR file, and run by a Java Virtual Machine on any platform. The requirements for running code anywhere have expanded with the introduction of containerization, however. Few shops are Java-only these days, and many are turning to containerization for true application portability,

  • Collaborative World Shaping: Why Open-Source Tech Matters in a For-Impact Future
    How many lives could be saved if there was a way to vastly cut down inefficiency and through bureaucracy, by problem solving at a global scale? Could technology help us reach more individuals in need more meaningfully, substantially helping people affected by disasters – in less time? The technology is already out there – but not enough people know about it. In 2017, Hurricane Irma—the strongest hurricane ever recorded in the Atlantic Ocean—made landfall; with widespread, “catastrophic” damage, disaster relief organizations were overwhelmed. “A lot of traditional means of crisis response are very top down, and they didn’t really kick in — we saw headlines about how the Red Cross didn’t show up to shelters,” said Greg Bloom, a community organizer and civic hacker who knew he had to step in to assist.
  • The First Open-Source Smart Contract Platform to be Started by Rootstock
    RSK Labs, formerly known as Rootstock, an Argentinian startup building the first open-source smart contract platform with a 2-way peg to Bitcoin.RSK Labs CEO Diego Gutiérrez Zaldívar on Bitcoin Smart Contracts Sidechain and Crypto Industry Challenges. Even though at this point of time the 2-way peg security of the RSK blockchain is still relying on a group of third parties called ‘Federation’, in the future the developers promise to bring a “trustless” automatic peg. How fast this happens to some degree depends on the overall miners support. The company says its goal is to add value and functionality to the Bitcoin ecosystem by enabling Ethereum-like smart-contracts, near instant payments and higher-scalability, and this past January after almost two years of development its mainnet dubbed Bamboo was finally launched.

Kernel and Graphics: PDS, VKMS and Nouveau

  • PDS 0.98s release
    PDS 0.98s is released with the following changes 1. Fix compilation issue on raspberry pi. 2. Minor rework and optimization on balance code path. 3. Fix wrong nr_max_tries in migrate_pending_tasks. This is mainly a bug fix and minor optimization release for 4.17. The rework of balance code doesn't go well, it actually make more overhead than current implement. Another rework which based on current implement is still on going, hopefully be included in next release.
  • PDS-MQ CPU Scheduler Revised For The Linux 4.17 Kernel With Minor Optimizations
    Alfred Chen announced this week the release of PDS-mq 0.98s, his latest patch-set of this CPU scheduler against the Linux 4.17 upstream code-base and includes minor optimization work and bug fixes. The PDS scheduler stands for the "Priority and Deadline based Skiplist multiple queue scheduler" that is derived from Con Kolivas' former BFS scheduler with Variable Run Queue (VRQ) support. PDS design principles are to be a simple CPU process scheduler yet efficient and scalable. PDS-mq differs from Con Kolivas' current MuQSS scheduler.
  • Add infrastructure for Vblank and page flip events in vkms simulated by hrtimer
    Since the beginning of May 2018, I have been diving into the DRM subsystem. In the beginning, nothing made sense to me, and I had to fight hard to understand how things work. Fortunately, I was not alone, and I had great support from Gustavo Padovan, Daniel Vetter, Haneen Mohammed, and the entire community. Recently, I finally delivered a new feature for VKMS: the infrastructure for Vblank and page flip events. At this moment, VKMS have regular Vblank events simulated through hrtimers (see drm-misc-next), which is a feature required by VKMS to mimic real hardware [6]. The development approach was entirely driven by the tests provided by IGT, more specifically the kms_flip. I modified IGT to read a module name via command line and force the use of it, instead of using only the modules defined in the code (patch submitted to IGT, see [1]). With this modification in the IGT, my development process to add a Vblank infrastructure to VKMS had three main steps as Figure 1 describes.
  • The State Of The VKMS Driver, Preparations For vBlank & Page Flip Events

  • Nouveau Gallium3D Moves Closer Towards OpenGL 4.5 Compliance
    While the RadeonSI and Intel i965 Mesa drivers have been at OpenGL 4.5 compliance for a while now, the Nouveau "NVC0" Gallium3D driver has been bound to OpenGL 4.3 officially. This Nouveau Gallium3D driver for NVIDIA "Fermi" graphics hardware and newer has effectively supported all of the OpenGL 4.4/4.5 extensions, but not officially. Originally the NVC0 problem for OpenGL 4.4 and newer was the requirement of passing the OpenGL Conformance Test Suite (CTS), which at first wasn't open-source. But now The Khronos Group has made it available to everyone as open-source. Additionally, the proper legal wrangling is in place so the Nouveau driver could become a conforming Khronos adopter under the X.Org Foundation without any associated costs/fees with Nouveau being purely open-source and primarily considered a community driver.

DistroWatch The Best Website For Distro Hoppers

The DistroWatch features release announcements of new versions of hundreds of Linux and other distributions. It does host reviews of distros, podcasts, and newsletters. DistroWatch first published by Ladislav Bodnar, the founder, and maintainer, on May 31, 2001. DistroWatch initially focused on Linux distributions. But later based on user requests, it went on adding different flavors of operating systems like BSD family, Android x86, Oracle Solaris, MINIX, and Haiku etc. The DistroWatch presents detailed information at one place in a very convenient manner. At the time of writing this article, the DistroWatch hosted information of more than 300 active distributions (referring the list of distros populated under drop-down feature on the first page of the DistroWatch) and more than hundred in queue. It is said that the DistroWatch lives out of advertising and donation. LinuxCD.org is the first to advertise on the DistroWatch site. Read more
