Intel's Gallium3D Driver Gains Optimization For Helping With Java OpenGL Performance

Tuesday 10th of September 2019 08:14:48 AM
In our recent Mesa 19.2 benchmarks of Intel's old and new (Gallium3D) OpenGL Linux drivers one of the rare areas where the new "Iris" driver performed behind the classic driver was with "j2dbench" that stresses the Java OpenGL pipeline. At the time it was unknown why the new driver was performing subpar for this Java graphics test, but now at least there's one optimization so far in addressing that shortcoming...

CompuLab's Airtop 3 Is The Most Powerful Fan-Less Computer We've Tested Yet

Monday 9th of September 2019 07:35:00 PM
The past month and a half we have been putting CompuLab's Airtop 3 computer through some demanding benchmarks and a variety of endurance workloads. With the Airtop 3 under test loaded with an 8-core / 16-thread Xeon processor, NVIDIA Quadro RTX 4000 graphics, and 64GB of RAM with NVMe SSD storage there were some concerns over thermal throttling and if this fan-less industrial PC design could really deal with the generated heat. But after all of this testing, the Airtop 3 continues running strong and another shining example of CompuLab's engineering strength.

Vega-Based Renoir APU Has The Same VCN Video Encode/Decode Block As Navi

Monday 9th of September 2019 02:00:07 PM
The next-generation AMD "Renoir" APU is turning into being an interesting successor over the existing Picasso APUs. While at first it was a letdown finding out that the APU is based on Vega and not their newer Navi architecture, follow-on open-source Linux patches have continued to show that it's more than a facsimile and in some areas like display and multimedia has blocks in common with Navi...

Ubuntu: Video Encoder Performance, Ubuntu Touch, LZ4 Compression

  • Clear Linux vs. Ubuntu 19.10 Video Encoder Performance On The Core i9 9900K

    Often when doing cross-distribution benchmarks, readers often comment on the performance of Clear Linux particularly for video encoding use-cases as surprisingly different from other distributions. Some argue that it's just over the default CPU frequency scaling governor or compiler flag defaults, so here is a look at that with Ubuntu 19.10 daily benchmarked against Clear Linux. On the same Core i9 9900K system I recently ran some benchmarks looking at Clear Linux vs. Ubuntu 19.10 and then Ubuntu 19.10 with various common tunables to make it more akin to Clear Linux. Ubuntu 19.10 was used due to its recent software components being at similar versions to Intel's rolling-release distribution.

  • Serge Hallyn: First experience with Ubuntu Touch

    For the past few weeks I’ve been using a nexus 4 running ubuntu touch as, mostly, my daily driver. I’ve enjoyed it quite a bit. In part that’s just the awesome size of the nexus 4. In part, it’s the ubuntu touch interface itself. If you haven’t tried it, you really should. (Sailfish ambiances are so much prettier, but ubuntu touch is much nicer to use – the quick switch to switch between two apps, for instance. Would that I could have both.). And in part it’s just the fact that it really feels like – is – a regular ubuntu system.

  • Ubuntu 19.10 to use LZ4 compression to boot even faster

    anonical’s Ubuntu 19.10 “Eoan Ermine” will boot even faster than its predecessor, Ubuntu 19.04 “Disco Dingo” according to Ubuntu’s kernel team. After extensive testing on a variety of compression options on the Ubuntu installation image, Canonical engineers determined that the LZ4 decompression method provided a most appreciable gain in speed.

The Vivaldi 2.8 Release (Proprietary)

  • Vivaldi 2.8 Released with Unified Sync Support for Desktop and Android

    Vivaldi Technologies released today the Vivaldi 2.8 web browser for desktop platforms, including GNU/Linux, macOS, and Windows, an incremental update that adds significant improvements. With Vivaldi 2.8, Vivaldi Technologies continues to give desktop users full control over their browsing experience by adding various improvements across the board, starting with Vivaldi Sync, which now lets you sync bookmarks, passwords, history, notes, and autofill information across desktop and mobile. That's right, starting with Vivaldi 2.8, all your browsing data will be automatically synchronized between your installations of Vivaldi on desktop platforms, such as Linux, Mac, or Windows, and your mobile device where Vivaldi for Android is installed if you use Vivaldi Sync.

  • New Version Vivaldi Web Browser Has Been Released, Install in Ubuntu/Linux

    Vivaldi is the new web browser compare to other famous browsers, the initial release of Vivaldi was in January, 2015. It has improved a lot and evolved since the first release. Basically it is based on the open-source frameworks of Chromium, Blink and Google's V8 JavaScript engine and has a lot of great feature which I will table later. It is known to be the most customizable browser for power users, debuts features that make browsing more personal than ever before. Do we really need another browser? Since we already have a lot of them such as mostly used Firefox, Chrome, Opera and so on. The former CEO of Opera Software Jon Von Tetzchner didn't liked the direction of Opera Web Browser and said "Sadly, it is no longer serving its community of users and contributors - who helped build the browser in the first place." Then created a web browser which has to be fast, rich feature, highly flexible and puts the user first, so Vivaldi was born.

  • Vivaldi 2.8: Inspires new desktop and mobile experiences

  • Skidmap malware drops LKMs on Linux machines to enable cryptojacking, backdoor access [Ed: This is not a "Linux" issue any more than Adobe Photoshop malicious files are a "Windows" issue ]

    Researchers have discovered a sophisticated cryptomining program that uses loadable kernel modules (LKMs) to help infiltrate Linux machines, and hides its malicious activity by displaying fake network traffic stats. Dubbed Skidmap, the malware can also grant attackers backdoor access to affected systems by setting up a secret master password that offers access to any user account in the system, according to Trend Micro threat analysts Augusto Remillano II and Jakub Urbanec in a company blog post.

  • Linux for ethical hackers 101

    In order to familiarize yourself with the full range of ethical hacking tools, it is important to be conversant with the Linux OS. As the systems engineer Yasser Ibrahim said in a post on Quora: “In Linux you need to understand from the basics to the advanced, learn the console commands and how to navigate and do everything from your console, also shell programming (not a must, but always preferable), know what a kernel is and how it works, understand the Linux file systems, how to network on Linux.”
