Fedora Linux 31 Enters Beta, Says Goodbye to 32-Bit Systems

Wednesday 18th of September 2019 04:01:00 PM
The Fedora Project has announced the general availability for public testing of the beta release of the upcoming Fedora 31 operating system.

Fedora 31 has been in development since early this summer and the beta version is now available to download for those who want to get an early taste of what's coming in the final release later this fall. The most important change in the Fedora 31 release is the fact that there won't be any 32-bit (i386) ISO images released, nor software repositories.

"We recognize that this means newer Fedora releases will no longer work on some older hardware, but the fact is there just hasn’t been enough contributor interest in maintaining i686, and we can provide greater benefit for the majority of our users by focusing on modern architectures," said Matthew Miller, Fedora Project Leader.

Another interesting change in the Fedora 31 release is the availabilit... (read more)

Canonical Outs New Linux Kernel Security Update for All Supported Ubuntu OSes

Wednesday 18th of September 2019 02:51:00 PM
Canonical released today a new Linux kernel security update for all supported Ubuntu releases to address three vulnerabilities across all supported architectures.

The new Linux kernel security update addresses three vulnerabilities affecting the Ubuntu 19.04 (Disco Dingo), Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 16.04 LTS (Xenial Xerus), Ubuntu 14.04 ESM (Trusty Tahr), and Ubuntu 12.04 ESM (Precise Pangolin) operating systems.

The first security issue addressed in this update is a a buffer overflow (CVE-2019-14835) discovered by Peter Pi in Linux kernel's virtio network backend (vhost_net) implementation, which could allow an attacker in the guest system to either execute arbitrary code in the host OS or crash the host operating system by causing a denial of service.

Linux Kernel 5.3 Officially Released, Here's What's New

Sunday 15th of September 2019 11:07:00 PM
Linus Torvalds announced today the release of the Linux 5.3 kernel series, a major that brings several new features, dozens of improvements, and updated drivers.

Two months in the works and eight RC (Release Candidate) builds later, the final Linux 5.3 kernel is now available, bringing quite some interesting additions to improve hardware support, but also the overall performance. Linux kernel 5.3 had an extra Release Candidate because of Linus Torvalds' travel schedule, but it also brought in a few needed fixes.

"Even if the reason for that extra week was my travel schedule rather than any pending issues, we ended up having a few good fixes come in, including some for some bad Btrfs behavior. Yeah, there's some unnecessary noise in there too (like the speling fixes), but we also had several last-minute reverts for things that caused issues," said Linus Torvalds.

Thursday 12th of September 2019 03:10:00 PM
The KDE Project announced that the next LTS (Long Term Support) series of their acclaimed KDE Plasma desktop environment for Linux-based operation systems will be KDE Plasma 5.18.

The current LTS (Long Term Support) series of the KDE Plasma desktop environment is KDE Plasma 5.12 LTS, which recently got its last scheduled maintenance update, KDE Plasma 5.12.9, which means that it actually reached end of life and will no longer receive point release except only if critical security issues or bugs need to be addressed.

Therefore, the KDE Project talked with various GNU/Linux distribution vendors about which next LTS series of the KDE Plasma desktop environment will suit them, and two of the biggest distros requested that the next long-term supported KDE Plasma series will be KDE Plasma 5.18, which was slated for rel...

Ubuntu 19.10 "Eoan Ermine" Promises More Boot Speed Improvements

Wednesday 11th of September 2019 03:22:00 PM
Colin Ian King, a Ubuntu Engineer working in the Kernel Team at Canonical, published a blog article with some of the boot improvements made in the upcoming Ubuntu 19.10 operating system.

According to Colin Ian King, the Ubuntu Kernel Team worked hard during the past few months to find a faster compression/decompression algorithm for the upcoming Ubuntu 19.10 (Eoan Ermine) operating system, which will hit the streets later this fall on October 17th.

The Ubuntu Kernel Team benchmarked six compression methods for the initramfs, including BZIP2, GZIP, LZ4, LZMA, LZMO and XZ, to measure the loading time of the Linux kernel, as well as the decompression time. The benchmarking was conducted on x86 configurations using the x86 TSC (Time Stamp Counter).

In the end, they realized that LZ4 is the best compression/decompression method for Ubuntu 19.10 (Eoan Ermine) as BZ... (read more)
