How do I find out my timezone in Linux?
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.

New Rule Forbids GNOME Shell Extensions Made Using AI-Generated Code
An anonymous reader shared this report from Phoronix:
Due to the growing number of GNOME Shell extensions looking to appear on extensions.gnome.org that were generated using AI, it's now prohibited. The new rule in their guidelines note that AI-generated code will be explicitly rejected:
"Extensions must not be AI-generated
While it is not prohibited to use AI as a learning aid or a development tool (i.e. code completions), extension developers should be able to justify and explain the code they submit, within reason.
Submissions with large amounts of unnecessary code, inconsistent code style, imaginary API usage, comments serving as LLM prompts, or other indications of AI-generated output will be rejected."
In a blog post, GNOME developer Javad Rahmatzadeh explains that
"Some devs are using AI without understanding the code..."

Is the R Programming Language Surging in Popularity?
The R programming language "is sometimes frowned upon by 'traditional' software engineers," says the CEO of software quality services vendor Tiobe, "due to its unconventional syntax and limited scalability for large production systems." But he says it "continues to thrive at universities and in research-driven industries, and "for domain experts, it remains a powerful and elegant tool."
Yet it's now gaining more popularity as statistics and large-scale data visualization become important (a trend he also sees reflected in the rise of Wolfram/Mathematica). That's according to December's edition of his TIOBE Index, which attempts to rank the popularity of programming languages based on search-engine results for courses, third-party vendors, and skilled engineers. InfoWorld explains:
In the December 2025 index, published December 7, R ranks 10th with a 1.96% rating. R has cracked the Tiobe index's top 10 before, such as in April 2020 and July 2020, but not in recent years. The rival Pypl Popularity of Programming Language Index, meanwhile, has R ranked fifth this month with a 5.84% share. "Programming language R is known for fitting statisticians and data scientists like a glove," said Paul Jansen, CEO of software quality services vendor Tiobe, in a bulletin accompanying the December index...
Although data science rival Python has eclipsed R in terms of general adoption, Jansen said R has carved out a solid and enduring niche, excelling at rapid experimentation, statistical modeling, and exploratory data analysis. "We have seen many Tiobe index top 10 entrants rising and falling," Jansen wrote. "It will be interesting to see whether R can maintain its current position."
"Python remains ahead at 23.64%," notes TechRepublic, "while the familiar chase group behind it holds steady for the moment. The real movement comes deeper in the list, where SQL edges upward, R rises to the top 10, and Delphi/Object Pascal slips away... SQLclimbs from tenth to eighth at 2.10%, adding a small +0.11% that's enough to move it upward in a tightly packed section of the table. Perl holds ninth at 1.97%, strengthened by a +1.33% gain that extends its late-year resurgence."
It's interesting to see how TIOBE's ranking compare with PYPL's (which ranks languages based solely on how often language tutorials are searched on Google):
TIOBE PYPL
Python Python
C C/C++
C++ Objective-C
Java Java
C# R
JavaScript JavaScript
Visual Basic Swift
SQL C#
Perl PHP
R Rust
Despite their different methodologies, both lists put Python at #1, Java at #5, and JavaScript at #7.

System76 Launches First Stable Release of COSMIC Desktop and Pop!_OS 24.04 LTS
This week System76 launched the first stable release of its Rust-based COSMIC desktop environment. Announced in 2021, it's designed for all GNU/Linux distributions — and it shipping with Pop!_OS 24.04 LTS (based on Ubuntu 24.04 LTS).
An anonymous reader shared this report from 9to5Linux:
Previous Pop!_OS releases used a version of the COSMIC desktop that was based on the GNOME desktop environment. However, System76 wanted to create a new desktop environment from scratch while keeping the same familiar interface and user experience built for efficiency and fun. This means that some GNOME apps have been replaced by COSMIC apps, including COSMIC Files instead of Nautilus (Files), COSMIC Terminal instead of GNOME Terminal, COSMIC Text Editor instead of GNOME Text Editor, and COSMIC Media Player instead of Totem (Video Player).
Also, the Pop!_Shop graphical package manager used in previous Pop!_OS releases has now been replaced by a new app called COSMIC Store.
"If you're ambitious enough, or maybe just crazy enough, there eventually comes a time when you realize you've reached the limits of current potential, and must create something completely new if you're to go further..." explains System76 founder/CEO Carl Richell:
For twenty years we have shipped Linux computers. For seven years we've built the Pop!_OS Linux distribution. Three years ago it became clear we had reached the limit of our current potential and had to create something new. Today, we break through that limit with the release of Pop!_OS 24.04 LTS with the COSMIC Desktop Environment.
Today is special not only in that it's the culmination of over three years of work, but even more so in that System76 has built a complete desktop environment for the open source community...
I hope you love what we've built for you. Now go out there and create. Push the limits, make incredible things, and have fun doing it!

'Free Software Awards' Winners Announced: Andy Wingo, Alx Sa, Govdirectory
This week the Free Software Foundation honored Andy Wingo, Alx Sa, and Govdirectory with this year's annual Free Software Awards (given to community members and groups making
"significant" contributions to software freedom):
Andy Wingo is one of the co-maintainers of GNU Guile,
the official extension language of the GNU operating system and the
Scheme "backbone" of GNU
Guix. Upon receiving the award, he stated: "Since I learned
about free software, the vision of a world in which hackers freely
share and build on each others' work has been a profound inspiration
to me, and I am humbled by this recognition of my small efforts in
the context of the Guile Scheme implementation. I thank my
co-maintainer, Ludovic Courtès, for his comradery over the years: we
are just building on the work of the past maintainers of Guile, and I
hope that we live long enough to congratulate its many future
maintainers."
The 2024 Award for
Outstanding New Free
Software Contributor went to Alx Sa for work on the GNU
Image Manipulation Program (GIMP). When asked to comment, Alx
responded: "I am honored to receive this recognition! I started
contributing to the GNU Image Manipulation Program as a way to return
the favor because of all the cool things it's allowed me to do.
Thanks to the help and mentorship of amazing people like Jehan Pagès,
Jacob Boerema, Liam Quin, and so many others, I hope I've been able
to help other people do some cool new things, too."
Govdirectory was presented
with this year's Award
for Projects of Social Benefit, given to a project or team
responsible for applying free software, or the ideas of the free
software movement, to intentionally and significantly benefit
society. Govdirectory provides a collaborative and fact-checked
listing of government addresses, phone numbers, websites, and social
media accounts, all of which can be viewed with free software and
under a free license, allowing people to always reach their
representatives in freedom...
The FSF plans to further highlight the Free Software Award winners
in a series of events scheduled for the new year to celebrate their
contributions to free software.

Applets Are Officially Going, But Java In the Browser Is Better Than Ever
"The entire java.applet package has been removed from JDK 26, which will release in March 2026," notes Inside Java.
But long-time Slashdot reader AirHog links to this blog post reminding us that
"Applets Are Officially Gone, But Java In The Browser Is Better Than Ever."
This brings to an official end the era of applets, which began in 1996. However, for years it has been possible to build modern, interactive web pages in Java without needing applets or plugins. TeaVM provides fast, performant, and lightweight tooling to transpile Java to run natively in the browser...
TeaVM, at its heart, transpiles Java code into JavaScript (or, these days, WASM). However, in order for Java code to be useful for web apps, much more is required, and TeaVM delivers. It includes a minifier, to shrink the generated code and obfuscate the intent, to complicate reverse-engineering. It has a tree-shaker to eliminate unused methods and classes, keeping your app download compact. It packages your code into a single file for easy distribution and inclusion in your HTML page. It also includes wrappers for all popular browser APIs, so you can invoke them from your Java code easily, with full IDE assistance and auto-correct.
The blog post also touts Flavour, an open-source
framework "for coding, packaging, and optimizing single-page apps implemented in Java... a full front-end toolkit with templates, routing, components, and more" to "build your modern single-page app using 100% Java."

Startup Successfully Uses AI to Find New Geothermal Energy Reservoirs
A Utah-based startup announced last week it used AI to locate a 250-degree Fahrenheit geothermal reservoir, reports CNN. It'll start producing electricity in three to five years, the company estimates — and at least one geologist believes AI could be an exciting "gamechanger" for the geothermal industry.
[Startup Zanskar Geothermal & Minerals] named it "Big Blind," because this kind of site — which has no visual indication of its existence, no hot springs or geysers above ground, and no history of geothermal exploration — is known as a "blind" system. It's the first industry-discovered blind site in more than three decades, said Carl Hoiland, co-founder and CEO of Zanskar. "The idea that geothermal is tapped out has been the narrative for decades," but that's far from the case, he told CNN. He believes there are many more hidden sites across the Western U.S.
Geothermal energy is a potential gamechanger. It offers the tantalizing prospect of a huge source of clean energy to meet burgeoning demand. It's near limitless, produces scarcely any climate pollution, and is constantly available, unlike wind and solar, which are cheap but rely on the sun shining and the wind blowing. The problem, however, has been how to find and scale it. It requires a specific geology: underground reservoirs of hot water or steam, along with porous rocks that allow the water to move through them, heat up, and be brought to the surface where it can power turbines... The AI models Zanskar uses are fed information on where blind systems already exist. This data is plentiful as, over the last century and more, humans have accidentally stumbled on many around the world while drilling for other resources such as oil and gas.
The models then scour huge amounts of data — everything from rock composition to magnetic fields — to find patterns that point to the existence of geothermal reserves. AI models have "gotten really good over the last 10 years at being able to pull those types of signals out of noise," Hoiland said...
Zanskar's discovery "is very significant," said James Faulds, a professor of geosciences at Nevada Bureau of Mines and Geology.... Estimates suggest over three-quarters of US geothermal resources are blind, Faulds told CNN. "Refining methods to find such systems has the potential to unleash many tens and perhaps hundreds of gigawatts in the western US alone," he said... Big Blind is the company's first blind site discovery, but it's the third site it has drilled and hit commercial resources. "We expect dozens, to eventually hundreds, of new sites to be coming to market," Hoiland said.... Hoiland says Zanskar's work shows conventional geothermal still has huge untapped potential.

Firefox Survey Finds Only 16% Feel In Control of Their Privacy Choices Online
Choosing your browser "is one of the most important digital decisions you can make, shaping how you experience the web, protect your data, and express yourself online," says the Firefox blog. They've urged readers to "take a stand for independence and control in your digital life."
But they also recently polled 8,000 adults in France, Germany, the UK and the U.S. on "how they navigate choice and control both online and offline" (attending in-person events in Chicago, Berlin, LA, and Munich, San Diego, Stuttgart):
The survey, conducted by research agency YouGov, showcases a tension between people's desire to have control over their data and digital privacy, and the reality of the internet today — a reality defined by Big Tech platforms that make it difficult for people to exercise meaningful choice online:
— Only 16% feel in control of their privacy choices (highest in Germany at 21%)
— 24% feel it's "too late" because Big Tech already has too much control or knows too much about them. And 36% said the feeling of Big Tech companies knowing too much about them is frustrating — highest among respondents in the U.S. (43%) and the UK (40%)
— Practices respondents said frustrated them were Big Tech using their data to train AI without their permission (38%) and tracking their data without asking (47%; highest in U.S. — 55% and lowest in France — 39%)
And from our existing research on browser choice, we know more about how defaults that are hard to change and confusing settings can bury alternatives, limiting people's ability to choose for themselves — the real problem that fuels these dynamics.
Taken together our new and existing insights could also explain why, when asked which actions feel like the strongest expressions of their independence online, choosing not to share their data (44%) was among the top three responses in each country (46% in the UK; 45% in the U.S.; 44% in France; 39% in Germany)... We also see a powerful signal in how people think about choosing the communities and platforms they join — for 29% of respondents, this was one of their top three expressions of independence online.
"For Firefox, community has always been at the heart of what we do," says their VP of Global Marketing, "and we'll keep fighting to put real choice and control back in people's hands so the web once again feels like it belongs to the communities that shape it."
At TwitchCon in San Diego Firefox even launched a satirical new online card game with a privacy theme called Data War.

The World's Electric Car Sales Have Spiked 21% So Far in 2025
Electrek reports:
EV and battery supply chain research specialists Benchmark Mineral Intelligence reports that 2.0 million electric vehicles were sold globally in November 2025, bringing global EV sales to 18.5 million units year-to-date. That's a 21% increase compared to the same period in 2024.
Europe was the clear growth leader in November, while North America continued to lag following the expiration of US EV tax credits. China, meanwhile, remains the world's largest EV market by a wide margin. Europe's EV market jumped 36% year-over-year in November 2025, with BEV sales up 35% and plug-in hybrid (PHEV) sales rising 39%. That brings Europe's total EV sales to 3.8 million units for the year so far, up 33% compared to January-November 2024... In North America, EV sales in the US did tick up month-over-month in November, following a sharp October drop after federal tax credits expired on September 30, 2025. Brands including Kia (up 30%), Hyundai (up 20%), Honda (up 11%), and Subaru (232 Solterra sales versus just 13 the month before) all saw gains, but overall volumes remain below levels when the federal tax credit was still available... [North America shows a -1% drop in EV sales from January to November 2025 vs. January to November 2024]
Year-to-date, EV sales in China are up 19%, with 11.6 million units sold. One of the biggest headlines out of China is exports. BYD reported a record 131,935 EV exports in November, blowing past its previous high of around 90,000 units set in June. BYD sales in Europe have jumped more than fourfold this year to around 200,000 vehicles, doubled in Southeast Asia, and climbed by more than 50% in South America...
"Overall, EV demand remains resilient, supported by expanding model ranges and sustained policy incentives worldwide," said Rho Motion data manager Charles Lester.
Beyond China, Europe, and North America, the rest of the world saw a 48% spike in EV sales in 2025 vs the same 11 months in 2024, representing 1.5 million EVs sold.
"The takeaway: EV demand continues to grow worldwide," the article adds, "but policy support — or the lack thereof — is increasingly shaping where this growth shows up."

How a 23-Year-Old in 1975 Built the World's First Handheld Digital Camera
In 1975, 23-year-old electrical engineer Steve Sasson joined Kodak. And in a new interview with the BBC, he remembers that he'd found the whole photographic process "really annoying.... I wanted to build a camera with no moving parts. Now that was just to annoy the mechanical engineers..."
"You take your picture, you have to wait a long time, you have to fiddle with these chemicals. Well, you know, I was raised on Star Trek, and all the good ideas come from Star Trek. So I said what if we could just do it all electronically...?"
Researchers at Bell Labs in the US had, in 1969, created a type of integrated circuit called a charge-coupled device (CCD). An electric charge could be stored on a metal-oxide semiconductor (MOS), and could be passed from one MOS to another. Its creators believed one of its applications might one day be used as part of an imaging device — though they hadn't worked out how that might happen. The CCD, nevertheless, was quickly developed. By 1974, the US microchip company Fairchild Semiconductors had built the first commercial CCD, measuring just 100 x 100 pixels — the tiny electronic samples taken of an original image. The new device's ability to capture an image was only theoretical — no-one had, as yet, tried to take an image and display it. (NASA, it turned out, was also looking at this technology, but not for consumer cameras....)
The CCD circuit responded to light but could only form an image if Sasson was somehow able to attach a lens to it. He could then convert the light into digital information — a blizzard of 1s and 0s — but there was just one problem: money. "I had no money to build this thing. Nobody told me to build it, and I certainly couldn't demand any money for it," he says. "I basically stole all the parts, I was in Kodak and the apparatus division, which had a lot of parts. I stole the optical assembly from an XL movie camera downstairs in a used parts bin. I was just walking by, you see it, and you take it, you know." He was also able to source an analogue to digital converter from a $12 (about £5 in 1974) digital voltmeter, rather than spending hundreds on the part. I could manage to get all these parts without anybody really noticing," he says....
The bulky device needed a way to store the information the CCD was capturing, so Sasson used an audio cassette deck. But he also needed a way to view the image once it was saved on the magnetic tape. "We had to build a playback unit," Sasson says. "And, again, nobody asked me to do that either. So all I got to do is the reverse of what I did with the camera, and then I have to turn that digital pattern into an NTSC television signal." NTSC (National Television System Committee) was the conversion standard used by American TV sets. Sasson had to turn only 100 lines of digital code captured by the camera into the 400 lines that would form a television signal.
The solution was a Motorola microprocessor, and by December 1975, the camera and its playback unit was complete, the article points out. With his colleague Jim Schueckler, Sasson had spent more than a year putting together the "increasingly bulky" device, that "looked like an oversized toaster."
The camera had a shutter that would take an image at about 1/20th of a second, and — if everything worked as it should — the cassette tape would start to move as the camera transferred the stored information from its CCD [which took 23 seconds]. "It took about 23 seconds to play it back, and then about eight seconds to reconfigure it to make it look like a television signal, and send it to the TV set that I stole from another lab...." In 1978, Kodak was granted the first patent for a digital camera. It was Sasson's first invention. The patent is thought to have earned Eastman Kodak billions in licensing and infringement payments by the time they sold the rights to it, fearing bankruptcy, in 2012...
As for Sasson, he never worked on anything other than the digital technology he had helped to create until he retired from Eastman Kodak in 2009.

More of America's Coal-Fired Power Plants Cease Operations
New England's last coal-fired power plant "has ceased operations three years ahead of its planned retirement date," reports the New Hampshire Bulletin.
"The closure of the New Hampshire facility paves the way for its owner to press ahead with an initiative to transform the site into a clean energy complex including solar panels and battery storage systems."
"The end of coal is real, and it is here," said Catherine Corkery, chapter director for Sierra Club New Hampshire. "We're really excited about the next chapter...." The closure in New Hampshire — so far undisputed by the federal government — demonstrates that prolonging operations at some facilities just doesn't make economic sense for their owners. "Coal has been incredibly challenged in the New England market for over adecade," said Dan Dolan, president of the New England Power Generators Association.
Merrimack Station, a 438-megawatt power plant, came online in the1960s and provided baseload power to the New England region for decades. Gradually, though, natural gas — which is cheaper and more efficient — took over the regional market... Additionally, solar power production accelerated from 2010 on, lowering demand on the grid during the day and creating more evening peaks. Coal plants take longer to ramp up production than other sources, and are therefore less economical for these shorter bursts of demand, Dolan said. In recent years, Merrimack operated only a few weeks annually. In 2024, the plant generated just0.22% of the region's electricity. It wasn't making enough money to justify continued operations, observers said.
The closure "is emblematic of the transition that has been occurring in the generation fleet in New England for many years," Dolan said. "The combination of all those factors has meant that coal facilities are no longer economic in this market."
Meanwhile Los Angeles — America's second-largest city — confirmed that the last coal-fired power plant supplying its electricity stopped operations just before Thanksgiving,
reports the Utah News Dispatch:
Advocates from the Sierra Club highlighted in a news release that shutting down the units had no impact on customers, and questioned who should "shoulder the cost of keeping an obsolete coal facility on standby...." Before ceasing operations, the coal units had been working at low capacities for several years because the agency's users hadn't been calling on the power [said John Ward, spokesperson for Intermountain Power Agency].
The coal-powered units "had a combined capacity of around 1,800 megawatts when fully operational," notes Electrek, "and as recently as 2024, they still supplied around 11% of LA's electricity. The plant sits in Utah's Great Basin region and powered Southern California for decades." Now, for the first time, none of California's power comes from coal.
There's a political hiccup with IPP, though: the Republican-controlled Utah Legislature blocked the Intermountain Power Agency from fully retiring the coal units this year, ordering that they can't be disconnected or decommissioned. But despite that mandate, no buyers have stepped forward to keep the outdated coal units online. The Los Angeles Department of Water and Power (LADWP) is transitioning to newly built, hydrogen-capable generating units at the same IPP location, part of a modernization effort called IPP Renewed. These new units currently run on natural gas, but they're designed to burn a blend of natural gas and up to 30% green hydrogen, and eventually100% green hydrogen. LADWP plans to start adding green hydrogen to the fuel mix in 2026.
"With the plant now idled but legally required to remain connected, serious questions remain about who will shoulder the cost of keeping an obsolete coal facility on standby," says the Sierra Club.
One of the natural gas units started commerical operations last Octoboer, with the second starting later this month, IPP spokesperson John Ward told Agency].

Rust in Linux's Kernel 'is No Longer Experimental'
Steven J. Vaughan-Nichols files this report from Tokyo:
At the invitation-only Linux
Kernel Maintainers Summit here, the top Linux maintainers decided, as Jonathan Corbet, Linux kernel developer, put it, "The consensus among the assembled developers is that Rust
in the kernel is no longer experimental — it is now a core part
of the kernel and is here to stay. So the 'experimental' tag
will be coming off." As Linux kernel maintainer Steven Rosted told
me, "There was zero pushback."
This has been a long time coming. This shift caps five years of
sometimes-fierce debate over whether the memory-safe language belonged alongside C at the heart of the world's most widely deployed open source operating system... It all began when Alex
Gaynor and Geoffrey
Thomas at the 2019 Linux Security Summit said that about
two-thirds of Linux kernel vulnerabilities come from memory safety
issues. Rust, in theory, could avoid these by using Rust's
inherently safer application programming interfaces (API)... In those early days, the plan was not to rewrite Linux in Rust; it still isn't, but to adopt it selectively where it can provide the
most security benefit without destabilizing mature C code. In short,
new drivers, subsystems, and helper libraries would be the first
targets...
Despite the fuss, more and more programs were ported to Rust. By
April 2025, the Linux kernel contained about 34 million lines of C
code, with only 25 thousand lines written in Rust. At the same time,
more and more drivers and higher-level utilities were being written
in Rust. For instance, the Debian Linux distro developers announced
that going forward, Rust
would be a required dependency in its foundational
Advanced Package Tool (APT).
This change doesn't mean everyone will need to use Rust. C is
not going anywhere. Still, as several maintainers told me, they
expect to see many more drivers being written in Rust. In particular,
Rust looks especially attractive for "leaf" drivers (network,
storage, NVMe, etc.), where the Rust-for-Linux
bindings expose safe wrappers over kernel C APIs. Nevertheless, for would-be kernel and systems programmers, Rust's
new status in Linux hints at a career path that blends deep
understanding of C with fluency in Rust's safety guarantees. This
combination may define the next generation of low-level development
work.
