Chinese-made Linux distribution deepin 23 Preview now available for download

Created and maintained by Chinese developers, deepin has long been considered one of the prettiest Linux-based operating systems. Understandably, due to its development happening in China, many people do not trust the distribution -- especially with biometrics being added. Not to mention the recent dustup over Taiwan and apparent ongoing genocide.

If you are someone that trusts deepin despite its country of origin, however, I have some really exciting news. Today, an official public preview of the upcoming deepin 23 becomes available for download. The developers highlight the inclusion of the new "Linglong" package format, atomic updates, and new repositories.

Following bug-related delay, Ubuntu Linux 22.04.1 LTS (Jammy Jellyfish) is finally here

Earlier this month, we shared the news that Ubuntu 22.04.1 LTS (code-named "Jammy Jellyfish") was being delayed. Sadly, the first point release of this wildly popular operating system version was being pushed back an entire week -- an absolute eternity in the world of Linux.

Well, folks, a week has passed, and thankfully, Canonical stayed true to its word (this time) and sorted the show-stopping Ubuntu Linux 22.04.1 issue. Yes, the major bug that caused snaps not to open on computers that used the OEM install option is now resolved. Even better, starting today, Canonical will being prompting Ubuntu 20.04 users to upgrade to Jammy Jellyfish.

New Ubuntu Linux version tragically delayed by serious bug

Canonical is usually quite dependable when it comes to Ubuntu releases. When a new version of the Linux-based operating system is expected, it usually becomes available on time.

Sadly, Ubuntu 22.04.1 won't become available today as expected -- a huge gut-punch to the Linux community. Why is Canonical disappointing fans of the operating system? Well, it seems a serious bug has caused the tragic delay. This serious issue causes snaps not to run on computers that use the OEM install option.

How to use SIGKILL to rapidly terminate containers in Kubernetes

Originating from Linux, which uses a Unix operating system, SIGKILL is a common command that developers use to terminate absolutely any process. Most commonly, if anything needs to be shut down immediately as it's causing damage to the system itself, then SIGKILL is the go-to signal to use.

Alongside Linux, SIGKILL has also found itself into any developer platform that manages container systems, with the most popular example of this being Kubernetes. As one of the most drastic signals that you can execute, SIGKILL will instantly terminate a process, without giving the system the opportunity to block or ignore the signal. With this, absolutely any processes that are connected to the process you’ve killed will also terminate.

Ubuntu-based Linux Mint 21 'Vanessa' now available for download

Just yesterday, we told you 4MLinux 40 was available for download. We also stated 4MLinux was an operating system that simply didn't need to exist. Another such distribution that isn't necessary anymore is Linux Mint. While Mint is a very solid OS, the brutal truth is, users would be wise to just use the operating system on which it is based -- Ubuntu.

But OK, many people have been using Linux Mint for years and they are not interested in changing their ways. Fair enough. If you are such a person that is prepared to "ride or die" with Linux Mint, today, the latest version of the operating system is officially released. Code-named "Vanessa," Linux Mint 21 can be downloaded immediately.

4MLinux 40.0 achieves stable status, but does anyone actually care?

You know what annoys me most about the Linux comuniuty? There are too many gosh darn operating systems based on the Linux kernel. And yes, too much choice can be a bad thing. You see, new Linux users often find themselves overwhelmed with the number of distributions from which to choose. Even worse, having many distros causes resources to be spread too thin. Desktop Linux would be better off if developers worked together on just a handful of operating systems (such as Debian and Fedora).

But no. The Linux community can't operate as a cohesive unit. Instead, it must be fragmented and confusing. Such is life, I suppose. With all of that said, version 40.0 of 4MLinux -- an operating system that probably doesn't need to exist -- is now available for download. The lightweight distribution has officially achieved stable status, and the developers are hopeful you will choose their offering over the plethora of alternatives.

Linux malware reaches an all time high

Malware magnifier

In the past cybercriminals have tended to shun Linux in favor of more widely used operating systems, but new data indicates that this trend is starting to shift.

Statistics from the Atlas VPN team show new Linux malware reached record numbers in the first half of 2022, with nearly 1.7 million samples being discovered. This puts it in second spot for the number of new samples even though it has only one percent of the OS market (not counting Android).

Dell's XPS 13 in particular has been lauded by professional reviewers and consumers alike thanks to its balance of power and elegance.

Download Linux Mint 21 'Vanessa' Beta now

Back in April, we learned that Linux Mint 21 would be named "Vanessa." Not much was revealed about the operating system at the time, but the developers did share a small bit of information. For instance, we now know that version 21 of Linux Mint will be based on Ubuntu 22.04, and as expected, the same three desktop environments will once again be offered -- Cinnamon, MATE, and Xfce.

Earlier this month, we also learned that the controversial systemd-oom will thankfully not be included in Linux Mint 21, while the Blueman Bluetooth manager will replace Blueberry. And now, the developers have shared something much more exciting than tidbits of information -- actual ISO files! Yes, the Beta of Linux Mint 21 "Vanessa" is now available to download.

TUXEDO Computers Pulse 15 Gen2 Linux laptop is powered by AMD Ryzen 7 5700U with 35W TDP

Now is a wonderful time to be in the market for a laptop that comes pre-loaded with a Linux-based operating system, as there are many great options. Linux laptops used to be a bit of a rarity, but as Linux gains popularity, these computers are becoming more commonplace. Currently, my recommendation is the HP Dev One which runs System76's Ubuntu-based Pop!_OS, as that notebook is affordable, well-built, and offers an overall excellent experience.

Today, yet another new Linux laptop is announced, this time by TUXEDO Computers. Well, technically it isn't entirely new, but actually, it is the second generation of its Pulse 15. Yes, after two years, the company has decided to refresh the computer with an AMD Ryzen 7 5700U processor (with 35W TDP) and 15.6-inch 165Hz WQHD (2560 x 1440) IPS display.
