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.

Author of Systemd Quits Microsoft To Prove Linux Can Be Trusted
Lennart Poettering has left Microsoft to co-found Amutable, a new Berlin-based company aiming to bring cryptographically verifiable integrity and deterministic trust guarantees to Linux systems. He said in a post on Mastodon that his "role in upstream maintenance for the Linux kernel will continue as it always has." Poettering will also continue to remain deeply involved in the systemd ecosystem. The Register reports: Linux celeb Lennart Poettering has left Microsoft and co-founded a new company, Amutable, with Chris Kuhl and Christian Brauner. Poettering is best known for systemd. After a lengthy stint at Red Hat, he joined Microsoft in 2022. Kuhl was a Microsoft employee until last year, and Brauner, who also joined Microsoft in 2022, left this month. [...]
It is unclear why Poettering decided to leave Microsoft. We asked the company to comment but have not received a response. Other than the announcement of systemd 259 in December, Poettering's blog has been silent on the matter, aside from the announcement of Amutable this week. In its first post, the Amutable team wrote: "Over the coming months, we'll be pouring foundations for verification and building robust capabilities on top."
It will be interesting to see what form this takes. In addition to Poettering, the lead developer of systemd, Amutable's team includes contributors and maintainers for projects such as Linux, Kubernetes, and containerd. Its members are also very familiar with the likes of Debian, Fedora, SUSE, and Ubuntu.

'Reverse Solar Panel' Generates Electricity at Night
Researchers at the University of New South Wales are developing a "reverse solar panel" that generates small amounts of electricity at night by harvesting infrared heat radiated from Earth. "In the past, scientists have demonstrated that a 'thermoradiative diode' can convert infrared radiation directly into electricity; when used to convert heat from Earth, they exploit the temperature difference between Earth and the night sky, generating a current directly from heat," notes ExtremeTech. "This approach completely eliminates the need for heat to generate steam, though the resulting capacity is fairly low." From the report: The researchers estimate they could generate only about a watt per square meter, which isn't much. One reason for the low output is that the Earth's atmosphere lessens the heat differential that drives the generative process; in space, though, that's not an issue.
Now, researchers believe that the ability to generate power in the moments between direct sunlight could help power satellites. That could be especially true in deep space, where periods without sunlight can be longer, and sunlight is often weaker; in these situations, losing electricity to heat loss is unacceptable.
Many satellites already use heat to generate electricity, though with a much more rarified "thermoelectric generator" that uses rare, expensive materials like plutonium to create heat. With thermoradiative diodes, the heat source can be the Sun-warmed body of the satellite itself.

UK's First Rapid-Charging Battery Train Ready For Boarding
An anonymous reader quotes a report from the Guardian: The UK's first superfast-charging train running only on battery power will come into passenger service this weekend -- operating a five-mile return route in west London. Great Western Railway (GWR) will send the converted London Underground train out from 5.30am to cover the full Saturday timetable on the West Ealing to Greenford branch line, four stops and 12 minutes each way, and now carrying up to 273 passengers, should its celebrity stoke up the demand.
The battery will recharge in just three and a half minutes back at West Ealing station between trips, using a 2,000kW charger connected to a few meters of rail that only becomes live when the train stops directly overhead. There are hopes within government and industry that this technology could one day replace diesel trains on routes that have proved difficult or expensive to electrify with overhead wires, as the decarbonization of rail continues.
The train has proved itself capable of going more than 200 miles on a single charge -- last year setting a world record for the farthest travelled by a battery-electric train, smashing a German record set in 2021. The GWR train and the fast-charge technology has been trialled on the 2.5-mile line since early 2024, but has not yet carried paying passengers.

Belkin's Wemo Smart Devices Will Go Offline On Saturday
Belkin is shutting down cloud support for most Wemo smart home devices on January 31, leaving only Thread-based models and devices already set up in Apple HomeKit functional. Everything else will lose remote access, voice assistant integrations, and future app updates. The Verge reports: The shut down was first announced in July and impacts most Wemo devices, ranging from smart plugs to a coffee maker, with the exception of a handful of Thread-based devices: the 3-way smart light switch (WLS0503), stage smart scene controller (WSC010), smart plug with Thread (WSP100), and smart video doorbell camera (WDC010). Wemo devices configured through Apple's HomeKit will also continue to work, but you have to set them up in HomeKit before January 31st if you want to use that option.
Other affected devices will only work manually after Saturday. If your Wemo device is still under warranty, you may be able to get a partial refund for it after cloud services shut down.

GNU gettext Reaches Version 1.0 After 30 Years
After more than 30 years of development, GNU gettext finally "crossed the symbolic 'v1.0' milestone," according to Phoronix's Michael Larabel. "GNU gettext 1.0 brings PO file handling improvements, a new 'po-fetch' program to fetch translated PO files from a translation project's site on the Internet, new 'msgpre' and 'spit' pre-translation programs, and Ocaml and Rust programming language improvements." From the report: With this v1.0 release in 2026, the "msgpre" and "spit" programs do involve.... Large Language Models (LLMs) in the era of AI: "Two new programs, 'msgpre' and 'spit', are provided, that implement machine translation through a locally installed Large Language Model (LLM). 'msgpre' applies to an entire PO file, 'spit' to a single message."
And when dealing with LLMs, added documentation warns users to look out for the licensing of the LLM in the spirit of free software. More details on the GNU gettext 1.0 changes via the NEWS file. GNU gettext 1.0 can be downloaded from GNU.org.

White House Scraps 'Burdensome' Software Security Rules
An anonymous reader quotes a report from SecurityWeek: The White House has announced that software security guidance issued during the Biden administration has been rescinded due to "unproven and burdensome" requirements that prioritized administrative compliance over meaningful security investments. The US Office of Management and Budget (OMB) has issued Memorandum M-26-05 (PDF), officially revoking the previous administration's 2022 policy, 'Enhancing the Security of the Software Supply Chain through Secure Software Development Practices' (M-22-18), as well as the follow-up enhancements announced in 2023 (M-23-16).
The new guidance shifts responsibility to individual agency heads to develop tailored security policies for both software and hardware based on their specific mission needs and risk assessments. "Each agency head is ultimately responsible for assuring the security of software and hardware that is permitted to operate on the agency's network," reads the memo sent by the OMB to departments and agencies. "There is no universal, one-size-fits-all method of achieving that result. Each agency should validate provider security utilizing secure development principles and based on a comprehensive risk assessment," the OMB added.
While agencies are no longer strictly required to do so, they may continue to use secure software development attestation forms, Software Bills of Materials (SBOMs), and other resources described in M-22-18.

Oracle May Slash Up To 30,000 Jobs
An anonymous reader shares a report: Oracle could cut up to 30,000 jobs and sell health tech unit Cerner to ease its AI datacenter financing challenges, investment banker TD Cowen has claimed, amid changing sentiment on Big Red's massive build-out plans.
A research note from TD Cowen states that finding equity and debt investors are increasingly questioning how Oracle will finance its datacenter building program to support its $300 billion, five-year contract with OpenAI.
The bank estimates the OpenAI deal alone is going to require $156 billion in capital spending. Last year, when Big Red raised its capex forecasts for 2026 by $15 billion to $50 billion, it spooked some investors. This year, "both equity and debt investors have raised questions about Oracle's ability to finance this build-out as demonstrated by widening of Oracle credit default swap (CDS) spreads and pressure on Oracle stock/bonds," the research note adds.
