Valve makes a few more small tweaks to the Steam Deck in the latest client update out now and ready to download. Not a big update but still quite a welcome one, as it fixes up a few minor issues plus the size of the client is now reduced.
Building up a settlement on the go is going to be a reality soon for RimWorld fans, as a fresh Beta version is now available and ready for testing with the Steam Deck.
Planned to release in full on April 6, they're giving mod creators a little extra time to prepare as it's upgraded a lot of the internals for the Steam integration so quite a few mods could break with this Beta. They said everything but a few mods should work, and you can test by opting into the "steam_deck" Beta branch (no password).
"The update focuses on Steam Deck changes and improvements. The UI changes make it easier to read on-screen text and type with the Steam Deck keyboard, and menus look a lot better. The controls make more sense now with improved scrolling, zooming, time control, and touch screen navigation. Overall, playing RimWorld on Steam Deck should be a lot smoother with more intuitive controls. There may be more changes on the way to get RimWorld a “Verified” status for Steam Deck." — Ludeon Studios
We can also plot the daily increase of new titles over time. Not sure if there is any particular reason but the number of new additions is markedly less this week compared to the previous week.
Want to try out a retro-styled arena survival FPS? Cathedral 3-D is now free to play so you've got nothing to lose. The free to play update included an overhaul of some gameplay elements like a redesigned magic system with easy teleportation.
This is a very fast-paced game, with the idea that you need to protect a box that contains your heart. It's absolutely manic and won't be for everyone but if you love a challenge this might be a good pick for you, especially now it's free.
Love roguelikes? Want a modern game that looks good and feels great to play? Jupiter Hell is what you need. The developers just released a nice big free upgrade too.
Version 1.3 Valhalla brings with it some pretty fun additions. There's a rework to multiple parts of the level generation, especially for Valhalla Spaceport, which has a new tough boss fight included. The Callisto area also got a big rework to add in some more variation and special mechanics involved with some other improvements to the level generation there, plus some weapon additions to each part of Callisto too. Some new visuals have been added, smoke now slows people down but not for the technician character who is "master of smoke" they say and plenty more.
For those who don't use it and are confused: the whole idea is that it produces high-resolution outputs from lower resolution inputs. It's one way to get good performance at 4K for example, for games that are a bit too resource intensive. It can work with many resolutions and the Steam Deck has FSR built-in.
Speed, or rather, responsiveness is an essential part of the software usage experience. This applies to every technology and domain, snaps included. Indeed, when it comes to snaps, the equation is a bit more complicated and slightly less straightforward because snaps are packaged as compressed, standalone applications and wrapped in a number of security confinement mechanisms, which set them apart from the classical desktop programs. However, the speed and responsiveness imperative remains.
Over the years, the snap development team has put a lot of effort into making snaps more accessible to the users. One of the main venues of focus has been the startup performance of applications. Notably, improvements in the use of the compression algorithm for snaps has led to 30-60% boost in startup times. Developers have started adopting the new LZO algorithm in their workflows, with positive results and feedback from the users. In today’s article, we want to share with you a fresh set of data from the KDE community.
The Alpine Linux project is pleased to announce the immediate availability of the releases:
3.12.10 3.13.8 3.14.4
The Free Software Fellowship team has recently blogged about Fedora's relationship with Iran and Russia. Now it is our turn in the Debian Community News Team to look at Debian with the explosive leak of 185 emails from debian-private about the arrest of Dmitry Bogatov in Russia.
Was Bogatov really a victim of the Russian state or was his arrest another example of smoke and mirrors, like a false-flag operation, encouraging western developers to show sympathy towards Russian cyberspies?
Can we spot the machinations of psyops officers in these email discussions?
In preparation for the upcoming Ubuntu 22.04 Long-Term Support update, due in April, Canonical has unveiled a new Ubuntu logo.
Ubuntu is, without a doubt, the most well-known desktop Linux distribution on the planet. Canonical, the Ubuntu creator, announced some exciting news yesterday: the Linux-based operating system is having a new logo!
The original Ubuntu logo consisted of a black rounded lowercase wordmark positioned to the right of a stylish abstract emblem consisting of a ring of three segments with three solid dots attached.
Forlinx has launched a “FET3568-C” module that runs Linux on a quad -A55 RK3568 with up to 8GB DDR4 and 16GB eMMC. The module powers an “OK3568-C” SBC with triple displays, 2x GbE, 4x USB, M.2 B-key, PCIe Gen2/SATA, and PCIe Gen3 x4.
Although Rockchip’s octa-core RK3588 has held center stage in recent weeks in product announcements such as Pine64’s QuartzPro64 SBC, the quad-core, Cortex-A55 RK3566 and more I/O rich RK3568 are the Rockchip SoCs that will dominate mainstream embedded Arm devices over the next few years. Forlinx has just released a FET3568-C compute module and sandwich-style OK3568-C dev kit built on the RK3568.
There are a few cool bits. Lagrange itself works really well, at least after a few settings tweaks. The Quest's hand tracking also works in Lagrange so there's no need for controllers. Instead you can point at the screen and pinch the air to interact with it. That's pretty neat but admittedly far from ergonomic. It gets tiring after just a few minutes with how much scrolling is needed.
One plus is being able to resize the screen to however big you want it and move it anywhere in your workspace. Did you know that if you have a big enough screen, Lagrange will intelligently switch from the mobile UI to the desktop UI?
I managed to even get my Station client certificate imported, though that was quite the exercise. Apparently adb doesn't have a good way of sending a piece of text to a connected device's clipboard, otherwise I could send my certificate that way. The Quest also doesn't have a built-in file browser, so copy pasting it from a file wasn't an option either. I ended up starting a simple, local http server on my laptop that served my certificate as a text file. From there I could connect to it from the Quest and copy paste the certificate into Lagrange. Phew!

If Kubernetes is so complicated that even Google is automating its setup, then it's worth paying attention when U.S. spy giant, the National Security Agency (NSA) points to strengthening it.
Kubernetes, as the NSA points out, provides "several flexibility and security benefits compared to traditional, monolithic software platforms." Unfortunately, that flexibility comes with a lot of moving pieces with their own cybersecurity considerations.
The NSA and Cybersecurity and Infrastructure Security Agency (CISA) recently updated their Kubernetes Hardening Guidance [PDF] which, while designed for government agencies, is still a great set of recommendations for independent organizations.

Opening a malicious advertisement or web page is already sufficient, the vulnerability does not need any interaction to do its work. See CVE-2022-0971.
Every month we review the work funded by Freexian’s Debian LTS offering. Please find the report for February below.
Senior human rights officials have repeated calls for a ban on the powerful Israeli spyware Pegasus until safeguards are in place to protect civilians from illegal hacking by governments.
Calls for a moratorium on the sale and use of the military-grade spyware were made on Wednesday at a hearing of the Inter-American Commission on Human Rights (IACHR) into widespread unlawful surveillance using Pegasus spyware against journalists and activists in El Salvador.
“There’s no doubt that malware marketed for complex security threats is being manipulated and used against the media and civil society … which is having a chilling effect on democracy,” said Scott Campbell, senior human rights and technology officer of the UN office of the high commissioner for human rights.
Despite being found guilty late last year for her role in sex crimes against minors, Ghislaine Maxwell, the “madam” and chief accomplice of the intelligence-linked pedophile and sex trafficker, Jeffrey Epstein, may soon walk free. A juror in the case, Scotty David, subsequently took credit for the jury’s decision to find Ghislaine Maxwell guilty and “inadvertently” revealed that he had incorrectly answered a pre-trial questionnaire. As a result, the possibility of a mistrial, and Ghislaine walking free, now looms large.
David has some interesting connections, as he currently works for the Carlyle Group – the global investment firm whose ties to the bin Laden family during the early 2000s have come under scrutiny. Carlyle’s executives often have ties to intelligence, with one example being its former chairman and then chairman emeritus, Frank Carlucci, who had been deputy director of the CIA and, later, Reagan’s Secretary of Defense. Carlyle’s current co-founder and co-chairman David Rubenstein, as noted in this article from Free Press Report, served on the board of the influential Trilateral Commission during the same time as Jeffrey Epstein, while his ex-wife Alice Rogoff (divorced in 2017) had a very close working relationship with Ghislaine Maxwell, including with her now defunct “charity” the TerraMar Project. Given the fact that there are known ties between David’s employer and Ghislaine Maxwell, why has this potential conflict of interest gone unmentioned by mainstream media?
Not only that, but – according to a family member of one of the women who testified against Maxwell during her trial – David was connected with the journalist who would publish the now infamous, post-verdict report via Vicky Ward. Ward has been denounced by Epstein victims and others close to the case for having had a past “chummy” relationship with Ghislaine Maxwell she declined to disclose for years and for subsequently telling Ghislaine that Epstein victim Maria Farmer had been the person who had first reported Maxwell and Epstein to the FBI back in 1996. Farmer later claims that Ward’s lack of journalistic integrity, after promising to keep Farmer’s identity secret, had put her life in danger and forced her into hiding.
It seems that there is, yet again, a major cover-up in the works, one which involves major centers of financial and political power in New York City and beyond. In order to fully understand the sexual trafficking and blackmail operation that Maxwell and Epstein oversaw, and why powerful forces apparently continue to intervene in the case, one must first understand its genesis, particularly how and why Ghislaine Maxwell arrived in New York City. In this second installment of “Meet Ghislaine” (read Part 1 here), the beginnings of Ghislaine’s career – closely controlled by her father, Robert Maxwell, until his 1991 death – are followed in detail.
We, the undersigned human rights and civil society organizations, are alarmed by Iranian parliament’s move to ratify the general outlines of the draconian “Regulatory System for Cyberspace Services Bill,” previously known as the “User Protection Bill” and referred to hereafter as “the Bill.” If passed, the Bill will violate an array of human rights of people in Iran, including the right to freedom of expression and right to privacy. We urge the Iranian authorities to immediately withdraw the Bill in its entirety. We further call on the international community, along with states engaged in dialogue with Iranian authorities, to ensure that the promotion and protection of human rights in Iran is prioritized, including by urging Iran’s parliament to rescind the Bill as a matter of urgency.
While UN Human Rights Council member states will soon vote on whether to renew the mandate of the Special Rapporteur on Iran, the Iranian parliament is attempting to further curtail the rights of people inside Iran with passage of this Bill. If implemented, this will carry grave risks of increased and even complete communication blackouts in Iran, and it is likely to be used as a tool to conceal serious human rights violations.
Russia’s full-scale invasion of Ukraine includes a broad range of cyberattacks, such as DDoS attacks on websites, blocking mobile connections, and other forms of deliberate disruption. Access Now and the #KeepItOn coalition are documenting these attacks, some of which represent internet shutdowns and/or acts of censorship. They are exacerbating the humanitarian crisis in Ukraine — just as shutdowns have in other parts of the world.
When governments like Russia’s interfere with internet access or block communications platforms, they prevent human right defenders, journalists, activists, and the public from getting access to information and reporting what is happening on the ground. It is often a deliberate attempt to hide human rights violations and atrocities and amplify state propaganda by removing access to alternative news sources. It is imperative that the international community, including U.N. bodies, tech companies, telecommunications providers, and other relevant actors, act now to protect and maintain the communications infrastructure in Ukraine and demand accountability for those who damage it.
When Russia invaded Ukraine late last month, Dasha Tkachuk, like many Ukrainians, found herself relying on one app in particular: Telegram.
“It is impossible not to be on Telegram [right now] — everyone uses it,” said Tkachuk, a 23-year-old sociologist living in Kyiv.
Before the invasion, Tkachuk operated a channel on the app — which features instant messaging, public or private community-like channels, massive group chats and other social features — that shared studying opportunities for students. “We had a small audience of nearly 15,000 people, and advertisers were willing to pay nearly $30 for one post,” she said.
Her revenue from the app dried up on Feb. 24, when Russian troops first entered the country and her clients stopped placing ads. But Tkachuk quickly found a new way to use the app — she got to work setting up several Telegram channels explaining what was happening in Ukraine for Russian-speaking users.
“In Russia, people use Telegram to get the latest news just like Ukrainians do,” she said.
The app’s popularity in the region was strong even before the ongoing war, with it serving as among the most popular sources of news among Ukrainians between the ages of 18 and 24.
If it has a microchip in it, chances are, there are issues fixing it. Our members -- from repair, refurbishing and recycling businesses across every industry -- have been raising the alarm about how manufacturers are pushing to monopolize repair of everything from appliances, to farm equipment, to servers and routers and even hearing aids.
As we’ve built momentum for the Right to Repair across the country, supporting bills in 40 states, we believe it’s time for Congress to get off the sidelines.
Yesterday, March 16, the Repair Association, along with more than 50 different organizations, sent a letter to House Judiciary Committee Chairman Jerry Nadler, Ranking Member Jim Jordan; Subcommittee on Antitrust, Commercial, and Administrative Law Chairman David Cicilline, Ranking Member Ken Buck; and Subcommittee on Courts, Intellectual Property, and the Internet Chairman Hank Johnson, and Ranking Member Darrell Issa calling for the full House Judiciary Committee to hold a hearing on the Right to Repair. The letter includes signatures from trade associations, small businesses, public interest groups, environmental advocacy organizations, and agriculture groups.
