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.

This isn't a Windows thing, Linux as well should be more secure than the assumption that the OS with elevated privileges is secure enough, there is so much more Desktop Linux could be doing to make the users experience more secure.

Sometimes the Tech pres just gets it wrong..

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.

Linux 5.10 LTS Status and More Stables Releases of Linux Announced Today

  • Linux 5.10 LTS Will Only Be Maintained Until EOY 2022 Unless More Companies Step Up

    Announced a few years ago was the notion of "extended" LTS kernel versions whereby the long term support cycle would span six years rather than the usual two years for LTS kernels in providing maintenance and bug/security fixes to the codebase. This means Linux 5.4 LTS is supported until the end of 2025, Linux 4.19 until the end of 2024, and even Linux 4.14 until the start of 2024. But with the recently minted Linux 5.10 LTS at least for now it's only being committed to maintenance until the end of next year. There's been differing remarks/indications for how long the Linux 5.10 long-term support cycle would last with many expecting six years given that's what has been happening on recent LTS kernels -- even the Linux 4.4 kernel is being planned for maintenance until February 2022 and Linux 4.9 until 2023. Linux stable maintainer Greg Kroah-Hartman has now provided a more transparent answer on the Linux kernel mailing list stemming from the talk over how long Linux 5.10 will be maintained.

  • Three stable kernels

    Stable kernels 5.10.11, 5.4.93, and 4.19.171 have been released. They contain important fixes and users should upgrade.

  • 5.10.11
  • 5.4.93
  • 4.19.171

Security and FUD

  • Security updates for Wednesday

    Security updates have been issued by Arch Linux (sudo), CentOS (sudo), Debian (sudo), Fedora (kernel, php-pear, and sudo), Gentoo (cacti, mutt, and sudo), Mageia (sudo), openSUSE (sudo), Oracle (sudo), Red Hat (sudo), Scientific Linux (sudo), Slackware (sudo), SUSE (go1.14, go1.15, nodejs8, and sudo), and Ubuntu (libsndfile and sudo).

  • SolarWinds Cyberattack: Layered OT Security Creates Best Defense

    The recent SolarWinds supply chain cyberattacks serve to underscore an age-old cybersecurity tenant, and the reason we need to continue beating the drum as cybersecurity professionals: Use a layered approach to OT security. This incident highlights a rare, specific use case of a nation state threat actor, an Advanced Persistent Threat (APT). In this particular case, layers provided somewhat limited value, but helped keep the less skilled attackers – about 99% of those on the playing field – at bay. Technology boundaries can be used to lessen the impact of (but unfortunately not prevent) nation state APTs. They not only offer additional protection, they may also help expose the presence of APTs in your network. Let’s examine how they would have helped in the case of APTs like the Sunburst malware that infected SolarWinds Orion software and was downloaded by 18,000 organizations.

    This tool is known as libprocesshider and is an open-source tool available on Github that can be used to hide any Linux process with the help of the ld preloader.

AMD Schedutil vs. Performance Governor Benchmarks On Linux 5.11 Shows More Upside Potential

With a pending patch, the Linux 5.11 AMD Zen 2 / Zen 3 performance is looking very good as far as the out-of-the-box performance is concerned when using Schedutil as is becoming the increasingly default CPU frequency scaling governor on more distributions / default kernels. With the previously noted Linux 5.11 regression addressed from when the AMD CPU frequency invariance support was first introduced, the Schedutil performance from small Ryzen systems up through big EPYC hardware is looking quite good. But how much upside is left in relation to the optimal CPU frequency scaling performance with the "performance" governor? Here is a look at those benchmarks on Ryzen and EPYC for Schedutil vs. Performance on a patched Linux 5.11 kernel. Read more

  • Firecracker: start a VM in less than a second

    Initially when I read about Firecracker being released, I thought it was just a tool for cloud providers to use – I knew that AWS Fargate and https://fly.io used it, but I didn’t think that it was something that I could directly use myself. But it turns out that Firecracker is relatively straightforward to use (or at least as straightforward as anything else that’s for running VMs), the documentation and examples are pretty clear, you definitely don’t need to be a cloud provider to use it, and as advertised, it starts VMs really fast! So I wanted to write about using Firecracker from a more DIY “I just want to run some VMs” perspective. I’ll start out by talking about what I’m using it for, and then I’ll explain a few things I learned about it along the way.

  • How To Enable Hardware Accelerated Video Decode In Google Chrome, Brave, Vivaldi And Opera Browsers On Debian, Ubuntu Or Linux Mint

    Google Chrome 88 (and newer) has made hardware accelerated video decoding available on Linux, but it's not enabled by default. Google Chrome is not the only Chromium-based web browser to support hardware acceleration on Linux though. This article explains how to enable hardware-accelerated video decoding in Google Chrome, Brave, Vivaldi and Opera web browsers running on Debian, Ubuntu, Pop!_OS or Linux Mint (Xorg only). Using hardware-accelerated video decode in your web browser should result in using less CPU usage (and thus, less battery draining) when playing online videos. It's worth noting that Chromium web browser had patches that allowed making hardware accelerated video decoding available on Linux for some time, and some Linux distributions packaged it using those patches. So Chromium users have had hardware acceleration on Linux for some time, depending on their Linux distribution or if they installed the patched Chromium in some other way. E.g. on Ubuntu / Linux Mint there's a PPA with VA-API patched Chromium builds. Thus, these instructions may also work for Chromium browser, depending on how it's built.
