An anonymous reader shares a report: In a preprint titled "Can LIGO Detect Daylight Savings Time?," Reed Essick, former LIGO member and now a physicist at the University of Toronto, gives a simple answer to the paper's title: "Yes, it can." The paper, which has yet to be peer-reviewed, was recently uploaded to arXiv. That might seem like an odd connection. It's true that observational astronomy must contend with noise from light pollution, satellites, and communication signals. But these are tangible sources of noise that scientists can sink their teeth into, whereas daylight savings time is considerably more nebulous and abstract as a potential problem.
To be clear, and as the paper points out, daylight savings time does not influence actual signals from merging black holes billions of light-years away -- which, as far as we know, don't operate on daylight savings time. The "detection" here refers to the "non-trivial" changes in human activity having to do with the researchers involved in this kind of work, among other work- and process-related factors tied to the sudden shift in time. The presence of individuals -- whether through operational workflows or even their physical activity at the observatories -- has a measurable impact on the data collected by LIGO and its sister institutions, Virgo in Italy and KAGRA in Japan, the new paper argues.
To see why this might be the case, consider again the definition of gravitational waves: ripples in space-time. A very broad interpretation of this definition implies that any object in space-time affected by gravity can cause ripples, like a researcher opening a door or the rumble of a car moving across the LIGO parking lot. Of course, these ripples are so tiny and insignificant that LIGO doesn't register them as gravitational waves. But continued exposure to various seismic and human vibrations does have some effect on the detector -- which, again, engineers and physicists have attempted to account for. What they forgot to consider, however, were the irregular shifts in daily activity as researchers moved back and forth from daylight savings time. The bi-annual time adjustment shifted LIGO's expected sensitivity pattern by roughly 75 minutes, the paper noted. Weekends, and even the time of day, also influenced the integrity of the collected data, but these factors had been raised by the community in the past.

The
NixOS moderation team, which is theoretically
in charge of ensuring that community participation on the project's
repositories and
discussion forum remains welcoming and useful, has released
a joint resignation statement. This action was motivated by conflict with the project's steering council (SC), which has repeatedly overridden the moderation team, leading the team members to decide that they could not continue acting as moderators. Arian Van Putten, speaking for the whole team, writes:
The SC has also shown, in private and public conversations, their lack of understanding of basic principles of community management and open communication. They have mistaken quiet and a lack of controversy for success and peace. They have consistently become upset when there is criticism, and gone quiet on crucial issues in between. We have some fundamental conflicts in this community, which absolutely require discussion. Meanwhile, discussion with the SC has only become less effective.
We think that the goal of moderation should not be to avoid difficult conversations - it's to navigate those difficult conversations in ways that remain safe and constructive. We believe we've made considerable progress as a community on making those conversations happen, and we believe they need to happen more for the project to grow, not be suppressed. We thank everyone for the growth that we have seen, and for their efforts to avoid personal focus in discussion, especially recently.
The NixOS project has had problems with community moderation stretching back
more than a year. With the next steering council election coming up soon, it will be interesting to see whether the community selects a council that feels differently or not.
As with a mobile phone, a portable gaming device like the
Steam Deck can contain
lots of personal information that the owner would like to keep
secret—especially given that such devices can do far more than gaming.
Alberto Garcia worked with his colleagues at Igalia and people at
Valve, the company behind the
Steam gaming platform, to come
up with a new tool to manage encrypted filesystems for
SteamOS, which is a Linux
distribution optimized for gaming. Garcia gave a talk about that tool,
dirlock, at
Open
Source Summit Europe, which was held in Amsterdam in late August.
In the talk, he looked at the design process for
the encrypted-files feature, the alternatives considered, and why they made
the choices
they did.

BrianFagioli writes: Electronic Arts has agreed to a $55 billion buyout by Saudi Arabia's Public Investment Fund (PIF), private equity firm Silver Lake, and Jared Kushner's Affinity Partners, marking the largest all-cash sponsor take-private deal ever. Shareholders will receive $210 per share, a 25 percent premium over EA's unaffected price, and once the transaction closes the company will be delisted from public markets. EA CEO Andrew Wilson will remain in charge, with the group arguing that private ownership will allow the publisher to innovate faster and expand its global footprint.
The deal, however, is already sparking controversy. PIF, a sovereign wealth fund controlled by the Saudi government, will effectively gain control of one of the most influential names in gaming. While investors stand to profit, many gamers and industry watchers are concerned about how Saudi ownership could shape EA's creative direction, monetization strategies, and role in esports. With regulatory approvals still pending, the takeover raises difficult questions about the intersection of gaming, politics, and global soft power.

"Computer science went from a future-proof career to an industry in upheaval in a shockingly small amount of time," writes Business Insider, citing remarks from UC Berkeley professor Hany Farid said during a recent episode of Nova's "Particles of Thought" podcast.
"Our students typically had five internship offers throughout their first four years of college," Farid said. "They would graduate with exceedingly high salaries, multiple offers. They had the run of the place. That is not happening today. They're happy to get one job offer...."
It's too easy to just blame AI, though, Farid said. "Something is happening in the industry," he said. "I think it's a confluence of many things. I think AI is part of it. I think there's a thinning of the ranks that's happening, that's part of it, but something is brewing..."
Farid, one of the world's experts on deepfake videos, said he is often asked for advice. He said what he tells students has changed... "Now, I think I'm telling people to be good at a lot of different things because we don't know what the future holds."
Like many in the AI space, Farid said that those who use breakthrough technologies will outlast those who don't. "I don't think AI is going to put lawyers out of business, but I think lawyers who use AI will put those who don't use AI out of business," he said. "And I think you can say that about every profession."

The F-Droid project has posted
an
urgent message regarding Google's plan to require developer
registration to install apps on Android devices.
The F-Droid project cannot require that developers register their
apps through Google, but at the same time, we cannot "take over"
the application identifiers for the open-source apps we distribute,
as that would effectively seize exclusive distribution rights to
those applications.
If it were to be put into effect, the developer registration decree
will end the F-Droid project and other free/open-source app
distribution sources as we know them today, and the world will be
deprived of the safety and security of the catalog of thousands of
apps that can be trusted and verified by any and all. F-Droid's
myriad users will be left adrift, with no means to install — or
even update their existing installed — applications.
