How do I find out my timezone in Linux?

nixCraft - Sun, 05/04/2025 - 17:35
You can find the timezone in Linux using the command line. The easiest way to do this is to type the "timedatectl" command and look for the "timezone" line when using modern Linux distros with systemd. There are other commands and ways to temporarily switch to a new timezone for date calculations.

'Harassed by Assasin's Creed Gamers, A Professor Fought Back With Kindness'

Slashdot.org - Sun, 05/04/2025 - 16:41
A Dartmouth College associate professor of Japanese literature and culture became a narrative consultant for Ubisoft's game Assassin's Creed Shadow (which launched in March). Sachi Schmidt-Hori's job "involved researching historical customs and reviewing scripts, not creating characters," writes the Associated Press. But when a trailer was released in May of 2024, some reacted to a game character named Yasuke who was a Black African samurai, according to the article, "with gamers criticizing his inclusion as 'wokeness' run amok". And they directed the blame at Schmidt-Hori: Gamers quickly zeroed in Schmidt-Hori, attacking her in online forums, posting bogus reviews of her scholarly work and flooding her inbox with profanity. Many drew attention to her academic research into gender and sexuality. Some tracked down her husband's name and ridiculed him, too. [One Reddit user described Schmidt-Hori as a "sexual degenerate who hate humanity because no man want her," while another called her a "professional woke social-justice warrior" who confirmed "fake history for Ubisoft."] Learning Yasuke was based on a real person did little to assuage critics. Asian men in particular argued Schmidt-Hori was trying to erase them, even though her role involved researching historical customs and reviewing scripts, not creating characters. Ubisoft told her to ignore the harassment, as did her friends. Instead, she drew inspiration from the late civil rights leader and congressman John Lewis. "I decided to cause 'good trouble,'" she said. "I refused to ignore." Schmidt-Hori began replying to some of the angry emails, asking the senders why they were mad at her and inviting them to speak face-to-face via Zoom. She wrote to an influencer who opposes diversity, equity and inclusion principles and had written about her, asking him if he intended to inspire the death threats she was getting. "If somebody said to your wife what people are saying to me, you wouldn't like it, would you?" she asked. The writer didn't reply, but he did take down the negative article about Schmidt-Hori. Others apologized. "It truly destroyed me knowing that you had to suffer and cancel your class and received hate from horrible people," one man wrote. "I feel somehow that you are part of my family, and I regret it. I'm sorry from the bottom of my heart." Anik Talukder, a 28-year-old south Asian man living in the United Kingdom, said he apologized at least 10 times to Schmidt-Hori after accepting her Zoom invitation to discuss his Reddit post about her... He was shocked the professor reached out to him and hesitant to speak to her at first. But they ended up having a thoughtful conversation about the lack of Asian representation in Western media and have stayed in touch ever since. "I learned a massive lesson," he said. "I shouldn't have made this person a target for no reason whatsoever."

Disneyland Imagineers Defend New Show Recreating Walt Disney as a Robot

Slashdot.org - Sun, 05/04/2025 - 15:41
"When Disneyland turns 70 this July, Main Street's Opera House will play host to the return of Walt Disney, who will sit down with audiences to tell his story in robot form," writes Gizmodo. But they point out Walt's granddaughter Johanna Miller wrote a Facebook post opposing the idea in November. ("They are Dehumanizing him. People are not replaceable...") The idea of a Robotic Grampa to give the public a feeling of who the living man was just makes no sense. It would be an imposter... You could never get the casual ness of his talking interacting with the camera his excitement to show and tell people about what is new at the park. You can not add life to one. Empty of a soul or essence of the man. Knowing that he did not want this. Having your predecessors tell you that this was out of bounds.... So so Sad and disappointed. The Facebook post claims that the son of a Disney engineer even remembers Walt saying that he never wanted to be an animatronic himself. And "Members of the Walt Disney family are said to be divided," reports the Los Angeles Times, "with many supporting the animatronic and some others against it, say those in the know who have declined to speak on the record for fear of ruining their relationships." So that Facebook post "raised anew ethical questions that often surround any project attempting to capture the dead via technology," their article adds, "be it holographic representations of performers or digitally re-created cinematic animations. And then some media outlets got a partial preview Wednesday, the Los Angeles Times reports: An early sculpt of what would become the animatronic was revealed, one complete with age spots on Disney's hands and weariness around his eyes — Imagineers stressed their intent is faithful accuracy — but much of the attraction remains secretive. The animatronic wasn't shown, nor did Imagineering provide any images of the figure, which it promises will be one of its most technically advanced. Instead, Imagineering sought to show the care in which it was bringing Disney back to life while also attempting to assuage any fears regarding what has become a much-debated project among the Disney community... Longtime Imagineer Tom Fitzgerald, known for his work on beloved Disney projects such as Star Tours and the Guardians of the Galaxy coaster in Florida, said Wednesday that "A Magical Life" has been in the works for about seven years. Asked directly about ethical concerns in representing the deceased via a robotic figurine, Fitzgerald noted the importance of the Walt Disney story, not only to the company but to culture at large... "What could we do at Disneyland for our audience that would be part of our tool kit vernacular but that would bring Walt to life in a way that you could only experience at the park? We felt the technology had gotten there. We felt there was a need to tell that story in a fresh way...." "Walt Disney — A Magical Life" will walk a fine line when it opens, attempting to inspire a new generation to look into Disney's life while also portraying him as more than just a character in the park's arsenal. "Why are we doing this now?" Fitzgerald says. "For two reasons. One is Disneyland's 70th anniversary is an ideal time we thought to create a permanent tribute to Walt Disney in the Opera House. The other: I grew up watching Walt Disney on television. I guess I'm the old man. He came into our living room every week and chatted and it was very casual and you felt like you knew the man. But a lot of people today don't know Walt Disney was an individual. They think Walt Disney is a company." And now nearly 60 years after his death, Disney will once again grace Main Street, whether or not audiences — or even some members of his family — are ready to greet him.

'KDE Plasma LTS Releases Are Dead'

Slashdot.org - Sun, 05/04/2025 - 14:20
With its Start menu-style application launcher and its bottom-of-the-screen taskbar, KDE Plasma is a "nice" and "traditional" desktop environment that's "also highly customizable," notes It's FOSS News. But there's a change coming... In contrast to other desktop environments, KDE offers a long-term support release (LTS) of Plasma, where bug fixes and security updates are provided for an extended period, with no new major changes being introduced. However, that is no longer the case now. Shared by Nate Graham, a prominent contributor within the KDE community, KDE has decided to stop working on LTS releases of Plasma, shifting its focus on extending support for the bug-fix and feature releases instead. The reasoning behind this move is multi-faceted, with factors such as inconsistent expectations from the community, developers' reluctance to work on older versions, and the lack of consistency in LTS support for Frameworks and Gear apps... I believe this move will provide Plasma users with a better Linux desktop experience, thanks to the extended bug-fix period, which will enhance the stability of each release. From Graham's blog post: It's no secret that our Plasma LTS ("Long-Term Support") product isn't great. It really only means we backport bug-fixes for longer than usual — usually without even testing them, since no Plasma developers enjoy living on or testing old branches. And there's no corresponding LTS product for Frameworks or Gear apps, leaving a lot of holes in the LTS umbrella. Then there's the fact that "LTS" means different things to different people; many have an expansive definition of the term that gives them expectations of stability that are impossible to meet. Our conclusion was that the fairly limited nature of the product isn't meeting anyone's expectations, so we decided to not continue it. Instead, we'll lengthen the effective support period of normal Plasma releases a bit by adding on an extra bug-fix release, taking us from five to six. We also revisited the topic of reducing from three to two Plasma feature releases per year, with a much longer bug-fix release schedule. It would effectively make every Plasma version a sort of mini-LTS, and we'd also try to align them with the twice-yearly release schedules of Kubuntu and Fedora. However, the concept of "Long-Term Support" doesn't go away just because we're not giving that label to any of our software releases anymore. Really, it was always a label applied by distros anyway — the distros doing the hard work of building an LTS final product out of myriad software components that were never themselves declared LTS by their own developers. It's a lot of work. So we decided to strengthen our messaging that users of KDE software on LTS distros should be reporting issues to their distro, and not to KDE. An LTS software stack is complex and requires a lot of engineering effort to stabilize; the most appropriate people to triage issues on LTS distros are the engineers putting them together. This will free up time among KDE's bug triagers and developers to focus on current issues they can reproduce and fix, rather than wasting time on issues that can't be reproduced due to a hugely different software stack, or that were fixed months or years ago yet reported to us anyway due to many users' unfamiliarity with software release schedules and bug reporting.

Tech Leaders Launch Campaign To Make CS and AI a Graduation Requirement

Slashdot.org - Sun, 05/04/2025 - 13:20
"Our future won't be handed to us," says the young narrator in a new ad from the nonprofit Code.org. "We will build it." "But how can we when the education we need is still just an elective?" says another young voice... The ad goes on to tout the power "to create with computer science and AI — the skills transforming every industry..." and ends by saying "This isn't radical. It's what education is supposed to do. Make computer science and AI a graduation requirement." There's also a hard-hitting new web site, which urges people to sign a letter of support (already signed by executives from top tech companies including Microsoft, Dropbox, AMD, Meta, Blue Origin, and Palantir — and by Steve Ballmer, who is listed as the chairman of the L.A. Clippers basketball team). Long-time Slashdot reader theodp says the letter ran in the New York Times, while this campaign will officially kick off Monday... Code.org teased the new Unlock8 campaign last month on social media as it celebrated a new Executive Order that makes K–12 AI literacy a U.S. priority, which it called a big win for CS & AI education, adding, "We've been building to this moment." The move to make CS and AI a graduation requirement is a marked reversal of Code.org's early days, when it offered Congressional testimony on behalf of itself and tech-led Computing in the Core reassuring lawmakers that: "Making computer science courses 'count' would not require schools to offer computer science or students to study it; it would simply allow existing computer science courses to satisfy a requirement that already exists."

FSF Announces Free Software Hackathon Honoring Its 40th Anniversary

Slashdot.org - Sun, 05/04/2025 - 11:34
Thursday the Free Software Foundation announced plans for a celebratory hackathon in November to improve free/libre software "in honor of its fortieth anniversary. The FSF has been campaigning for software freedom for over forty years. As part of its celebrations, the organization is inviting the wider free software community (both projects and individual contributors) to participate in a global, online hackathon to help improve important libre software projects. All free software projects, regardless of affiliation or (free) license, are invited to participate. As of now, the advanced GNU/Linux distribution and package manager GNU Guix, the boot software distribution GNU Boot, the media publishing system MediaGoblin, and the Free Software Directory, the FSF's catalog of useful free software, have announced that they will submit a project. Interested contributors are encouraged to review the hackathon guidelines, which the FSF has made available online... Hackathon contributions will be judged by a panel appointed by the FSF. The project and contributors making the most noteworthy contributions/patches will be given prizes by the Foundation. The hackathon will conclude with a closing ceremony. "The FSF's free software hackathon will be held November 21-23, 2025," according to the announcement. "Submissions will be open until May 27."

We May Be In a 'Post-Herd Immunity World', says Immunology Expert

Slashdot.org - Sun, 05/04/2025 - 10:34
Dr. Paul Offit, an expert on infectious disease and immunology, told the Guardian that "We're living in a post-herd-immunity world. I think the measles outbreak proves that. Measles — because it is the most contagious of the vaccine-preventable diseases, the most contagious human disease really — it is the first to come back." Three large outbreaks in Canada, Mexico and the US now account for the overwhelming majority of roughly 2,300 measles cases across the World Health Organization's six-country Americas region, according to the health authority's update this week. Risk of measles is considered high in the Americas, and has grown 11-fold compared with 2024. Only slightly behind, data released earlier this week from the European Centre for Disease Prevention and Control (ECDC) and WHO also noted that measles cases across Europe were up tenfold in 2024 compared to 2023. That data also indicated that the 2024 measles cases in Europe followed a seasonal pattern, which was not previously noted in 2021 through 2023. Of the European cases, which reportedly hit 35,212 for 2024, 87% were reported in Romania. The ECDC said the dip in vaccine rates has impacted the recent spike in measles, with only three countries, Hungary, Malta and Portugal, having coverage of 95% or more for both doses of the measles vaccine.

Security Researchers Create Proof-of-Concept Program that Evades Linux Syscall-Watching Antivirus

Slashdot.org - Sun, 05/04/2025 - 09:34
Slashdot reader Mirnotoriety shared this report from the Register: A proof-of-concept program has been released to demonstrate a so-called monitoring "blind spot" in how some Linux antivirus and other endpoint protection tools use the kernel's io_uring interface. That interface allows applications to make IO requests without using traditional system calls [to enhance performance by enabling asynchronous I/O operations between user space and the Linux kernel through shared ring buffers]. That's a problem for security tools that rely on syscall monitoring to detect threats... [which] may miss changes that are instead going through the io_uring queues. To demonstrate this, security shop ARMO built a proof-of-concept named Curing that lives entirely through io_uring. Because it avoids system calls, the program apparently went undetected by tools including Falco, Tetragon, and Microsoft Defender in their default configurations. ARMO claimed this is a "major blind spot" in the Linux security stack... "Not many companies are using it but you don't need to be using it for an attacker to use it as enabled by default in most Linux systems, potentially tens of thousands of servers," ARMO's CEO Shauli Rozen told The Register. "If you're not using io_uring then disable it, but that's not always easy with cloud vendors."
