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.

Should Physicists Study the Question: What is Life?
An astrophysicist at the University of Rochester writes that "many" of his colleagues in physics "have come to believe that a mystery is unfolding in every microbe, animal, and human." And it's a mystery that:
- "Challenges basic assumptions physicists have held for centuries"
- "May even help redefine the field for the next generation"
- "Could answer essential questions about AI."
In short, while physicists have favored a "reductionist" philosophy about the fundamental laws controlling the universe (energy, mattery, space, and time), "long-promised 'theories of everything' such as string theory, have not borne significant fruit:
There are, however, ways other than reductionism to think about what's fundamental in the universe. Beginning in the 1980s, physicists (along with researchers in other fields) began developing new mathematical tools to study what's called "complexity" — systems in which the whole is far more than the sum of its parts. The end goal of reductionism was to explain everything in the universe as the result of particles and their interactions. Complexity, by contrast, recognizes that once lots of particles come together to produce macroscopic things — such as organisms — knowing everything about particles isn't enough to understand reality...
Physicists have always been good at capturing the essential aspects of a system and casting those essentials in the language of mathematics... Now those skills must be brought to bear on an age-old question that is only just getting its proper due: What is life? Using these skills, physicists — working together with representatives of all the other disciplines that make up complexity science — may crack open the question of how life formed on Earth billions of years ago and how it might have formed on the distant alien worlds we can now explore with cutting-edge telescopes. Just as important, understanding why life, as an organized system, is different at a fundamental level from all the other stuff in the universe may help astronomers design new strategies for finding it in places bearing little resemblance to Earth. Analyzing life — no matter how alien — as a self-organizing information-driven system may provide the key to detecting biosignatures on planets hundreds of light-years away.
Closer to home, studying the nature of life is likely essential to fully understanding intelligence — and building artificial versions. Throughout the current AI boom, researchers and philosophers have debated whether and when large language models might achieve general intelligence or even become conscious — or whether, in fact, some already have. The only way to properly assess such claims is to study, by any means possible, the sole agreed-upon source of general intelligence: life. Bringing the new physics of life to problems of AI may not only help researchers predict what software engineers can build; it may also reveal the limits of trying to capture life's essential character in silicon.

Free Software Foundation Receives 'Historic' Donations Worth Nearly $900K - in Monero
On Wednesday (Christmas Eve), the Free Software Foundation announced it had received two major contributions totaling around $900,000 USD — in the cryptocurrency Monero.
The two donations "are among some of the largest private gifts ever made to the organization," the FSF said in a statement.
"The donors wish to remain anonymous," according to the FSF's statement:
The organization is in its annual winter fundraising drive, currently at three-quarters of its $400,000 USD winter goal, and will now switch its focus to a member drive thanks in part to these donations...
The donation will support the organization's technical team and infrastructure capacity, as well as strengthen its campaigns, education, licensing, and advocacy initiatives, and future opportunities. The FSF is seeking donations until year-end after which they aim to gain 100 associate members through its year-end fundraising ending January 16.
The FSF's executive director said the donations prove "that software freedom is recognized more and more as a principal issue today, at the core of several other social movements people care about like privacy, ownership, and the right to repair...
"We are proudly supported by a large variety of contributors who care about digital rights. All donations matter, whether $5 or $500,000."

Video Call Glitches Evoke Uncanniness, Damage Consequential Life Outcomes
Those brief freezes and audio hiccups that plague video calls are not the benign nuisances that most people assume them to be, according to a new study published in Nature that found glitches during virtual interactions can meaningfully damage hiring prospects, reduce trust in healthcare providers and even correlate with lower chances of being granted parole.
Researchers from Columbia, Cornell, and the University of Missouri-Kansas City conducted ten studies examining glitches across thousands of participants and real-world parole hearing transcripts. The core finding is that glitches harm interpersonal judgments because they break the illusion of face-to-face contact, triggering what psychologists call "uncanniness" -- a strange, creepy, or eerie feeling typically associated with humanoid robots or CGI characters that look almost but not quite human.
In one experiment, participants watching a telehealth pitch chose to work with a health professional 77% of the time when no glitches occurred, but only 61% when brief freezes were present. The job interview studies found similar patterns, and when researchers examined 472 Kentucky parole hearings conducted over Zoom, they found that inmates were granted parole 60% of the time in glitch-free hearings versus 48% when transcripts indicated technical problems had occurred.
The researchers ruled out simpler explanations like mere disruption or comprehension difficulties. Glitches inserted during natural pauses in speech -- where no information was lost -- still damaged evaluations. And critically, when participants watched presentations where a shared screen froze rather than a human face, glitches had no effect on judgments at all. The uncanniness only emerged when the technology broke the simulation of sitting across from another person.

Taiwan's iPass Releases Floppy Disk Pre-Paid Cash Card
Taiwan's iPass has released a limited-edition prepaid payment card shaped exactly like a 3.5-inch floppy disk. The company, perhaps rightly so, felt the need to include a warning on the product listing: "This product only has a card function and does not have a 3.5mm [sic] disk function, please note before purchasing."
The NFC-enabled novelty card went on sale starting Christmas Eve and comes in black or yellow finishes at 1:1 scale. It works across Taiwan's public transport network -- buses, trains, subways, taxis, and bike rentals -- as well as convenience stores like 7-Eleven and FamilyMart, supermarkets, pharmacies, and fast-food chains including McDonald's and Burger King.
The floppy disk joins an increasingly absurd lineup of iPass form factors. Previous releases have included, Tom's Hardware reports, a Motorola DynaTAC replica, model trains, a flip-flop, an LED-lit Godzilla snow globe, and a blood bag. Taiwan's PCHome24 online store currently lists 838 different iPass card designs. A standard card costs NT$100 (about $3.20) and comes without stored value.

Toll Roads Are Spreading in America
Toll roads are expanding across the U.S. as the traditional gas tax funding model for highways collapses. Indiana became the first state to authorize tolls on all of its existing interstate highways when Governor Mike Braun signed legislation in June.
The federal gas tax hasn't been raised since 1993. In fiscal 2024, the federal government spent $27 billion more on road maintenance than it collected from fuel taxes, and at state and local levels, fuel taxes covered barely a quarter of road spending. Drivers currently pay to access just 6,300 miles of America's roughly 160,000 miles of highway.
Most tolling projects have enjoyed bipartisan support -- Florida has more toll roads by distance than any other state, and Texas is second. But as Republicans embrace populism, the politics are shifting. In New York, almost all state Republicans fought congestion pricing, and President Donald Trump attempted to shut it down after taking office. Some Republicans now want to buy back pay-to-drive roads and make them free.

Rocket Crashes in Brazil's First Commercial Launch
The first-ever commercial rocket launched at Brazil's Alcantara Space Center crashed soon after liftoff late earlier this week, dealing a blow to Brazilian aerospace ambitions and shares of South Korean satellite launch company Innospace. From a report: The rocket began its vertical trajectory as planned after liftoff [Monday] at 10:13 p.m. local time (0113 GMT) but fell to the ground after something went wrong 30 seconds into its flight, Innospace CEO Kim Soo-jong said in a letter to shareholders.
The craft crashed within a pre-designated safety zone and did not harm anyone, he said. Brazil's air force said firefighters were sent to analyze the wreckage and impact zone. "We are deeply sorry that we failed to meet the expectations of our shareholders who supported our first commercial launch," the CEO wrote in the letter, which was posted on the company's website on December 23.
Innospace shares plunged nearly 29% in Seoul in its biggest daily drop and heaviest daily trading volume since its July 2024 listing.

Mesh Networks Are About To Escape Apple, Amazon and Google Silos
After more than two decades of promises and false starts in the mesh networking space, the smart home standards that Apple, Amazon and Google have each championed are finally set to escape their respective brand silos and work together in a single unified network.
Starting January 1, 2026, Thread 1.4 becomes the Thread Group's only certified standard, bringing a crucial new capability called credential sharing. Devices from different manufacturers can now securely join the same mesh network -- an Amazon Echo Show and an Apple HomePod mini in the same house will both be able to control the same Nanoleaf lightbulb. This marks a significant departure from Thread 1.3, released in 2022, where each brand's mesh network connected only to devices from that same brand.
The Thread Group launched in 2014 as a coalition led by Arm, Google's Nest Labs, and Samsung, later welcoming Apple and Amazon into the fold. Thread 1.4 handles low-power smart home devices and sensors, but homes also need high-bandwidth connections for laptops and phones. Wi-Fi 7 mesh serves that purpose and the Matter protocol acts as a translation layer between the two different mesh networks. Both Wi-Fi 7 and Matter arrived in products on store shelves in 2025.

Driverless Future Gains Momentum With Global Robotaxi Deployments
The global push to put autonomous taxis on public roads is accelerating as ride-hailing companies and technology firms advance from pilot programs toward limited commercial rollouts in cities across China, the United States, Europe and the Middle East.
WeRide and Uber launched Level 4 fully driverless robotaxi operations in Abu Dhabi in November and began offering robotaxi passenger rides on Uber's platform in Dubai the following month. Amazon's Zoox started offering free rides to select early users in parts of San Francisco in November after launching its autonomous ride-hailing service on the Las Vegas Strip in September. Alphabet's Waymo now operates services in Phoenix, San Francisco, and Los Angeles -- the latter two having launched in June and November 2024 respectively.
Baidu's Apollo Go has been operating without safety drivers in Chongqing and Wuhan since securing permits in August 2022 and has since expanded to Shenzhen and Beijing. Pony.ai launched paid robotaxi services in Guangzhou in February and Shanghai in August. Tesla began a limited paid robotaxi rollout in Austin, Texas in June using Model Y SUVs, though the vehicles still require a safety monitor onboard. The expansion will continue in 2026: Waymo plans to launch an autonomous ride-hailing service in London, and Momenta is preparing a luxury robotaxi service in Abu Dhabi through a partnership with Mercedes-Benz and UAE taxi operator Lumo.

NASA Chief Says US Will Return To Moon Within Trump's Second Term
NASA Administrator Jared Isaacman, who was confirmed by the Senate just last week after a turbulent nomination process that stretched across most of 2025, said Friday that the United States will return to the moon within President Donald Trump's second term. Isaacman made the comments during an interview on CNBC, calling Trump's recommitment to lunar exploration key to unlocking what he described as an "orbital economy." He said: "We want to have that opportunity to explore and realize the scientific, economic and national security potential on the moon," he said.
The potential opportunities include establishing space data centers and infrastructure on the moon, as well as mining Helium-3, a rare gas embedded in the lunar surface that could serve as fuel for fusion power. NASA is currently working on its Artemis campaign alongside SpaceX, Blue Origin, and Boeing. Trump's One Big Beautiful Bill Act allocated $9.9 billion to the agency earlier this year.
The Artemis II mission, NASA's first crewed test flight using the Space Launch System rocket and Orion spacecraft, is expected to launch in the near future. SpaceX is contracted to build the lunar landing system for the subsequent Artemis III mission. Isaacman was first nominated by Trump in December 2024 but had his nomination pulled in May over unspecified "prior associations." Trump renominated him in November.

New York To Require Social Media Platforms To Display Mental Health Warnings
Social media platforms with infinite scrolling, auto-play and algorithmic feeds will be required to display warning labels about their potential harm to young users' mental health under a new law, New York Governor Kathy Hochul announced on Friday. From a report: "Keeping New Yorkers safe has been my top priority since taking office, and that includes protecting our kids from the potential harms of social media features that encourage excessive use," Hochul said in a statement.
This month Australia imposed a social media ban for children under 16. New York joins states like California and Minnesota that have similar social media laws. The New York law includes platforms that offer "addictive feeds," auto play or infinite scroll, according to the legislation. The law applies to conduct occurring partly or wholly in New York but not when the platform is accessed by users physically outside the state.
