"What did four astronauts see, notice, and document as they traveled around the Moon during NASA's Artemis II mission?" asks a new NASA web page, offering some fascinating pictures and video: Through photographs, spoken observations, drawings, and annotations, the Artemis II crew created a unique scientific record - one that is now available to the science community and the public for further study... As part of the mission science plan, lunar scientists asked the Artemis II crew to watch for tiny flashes sparked by rocky fragments hitting the Moon. Even so, some scientists were astonished when astronauts reported seeing five extremely faint "pinprick" bursts of light from 46,000 miles away. After ruling out other sources - cosmic rays or reflections from the spacecraft - the science team confirmed the sightings... The impact flash observations happened during a planned loss of communications while the Artemis II crew was on the far side of the Moon... Apollo astronauts saw similar flashes from lunar orbit, but the Artemis crew likely caught the faintest ever seen with the unaided eye. From the brightness of the flashes, scientists estimated that incoming rocks were each no more than a couple of inches wide. Despite their size, they were traveling thousands of miles per hour, producing just enough light upon impact to be visible. The nearly hour-long total solar eclipse that the crew experienced while passing by the Moon's far side created ideal dark conditions for spotting such subtle bursts. With no atmosphere to slow or burn up incoming debris, projectiles slam freely into the lunar surface. The crew's direct observations of this process on the Moon's far side provided a rare dataset that will help us understand how often these small impacts occur, which is essential for assessing long-term risks to future lunar habitats and infrastructure... The crew reported seeing subtle hues of gray, black, brown, tan, white, green, and blue across the Moon's surface. This muted rainbow offers clues to the rocks and minerals that make up different lunar regions, helping scientists piece together how the Moon - and, by extension, Earth - evolved over time. "Amazing news," Mission Control responded when they heard about the flashes. Space.com reports that when a Mission Control operator looked over at the Science Evaluation Room, "they were jumping up and down, literally." NASA blogged this week that more than 800 gigabytes of Artemis II lunar science data - some previously unreleased - "have been uploaded to NASA's Planetary Data System, the public archive for NASA's planetary missions." This data release includes more than 11,000 full-resolution images and video of the Moon from the crew's handheld cameras and the Orion spacecraft's cameras, 8.5 hours of audio recordings of the crew's scientific observations of the lunar surface, and crew-annotated images... Along with this data, NASA has released the Artemis II Preliminary Lunar Science Report, the Artemis II Lunar Science Operations Report, and the Artemis II Lunar Science Data User Guide.

CNN reports: The FBI arrested a Canadian cybersecurity executive and ransomware expert as part of the investigation of a damaging hack that exposed the sensitive data of current and former FBI employees, according to court documents and people familiar the investigation. Edward Dubrovsky was arrested in the Philadelphia area in recent days... Dubrovsky is facing charges related to extortion and making threats. He has been transferred to Texas's Eastern District for a scheduled detention hearing, according to court records and a law enforcement official. FBI Director Kash Patel announced the arrest on Friday but did not disclose where it occurred or what role the man is suspected of playing in the hack. Patel also didn't name Dubrovsky, but CNN confirmed the defendant is believed to be tied to the FBI hack through multiple people familiar with the investigation... A LinkedIn profile under Dubrovsky's name lists years of experience in the Canadian cybersecurity industry and describes Dubrovsky as a 'globally recognized cybersecurity expert.' An Ed Dubrovsky is also the author of a book on handling ransomware negotiations with cybercriminals... There has also been an inquest at the FBI over how such a critical security lapse happened. The FBI determined that a contractor managing the bureau's jobs portal failed to update software "explicitly issued to secure the platform," [senior FBI cyber official, Brett Leatherman said last week]. The FBI has "removed the contractor," he said. The software in question is a human-resources platform made by Oracle, ShinyHunters has said. The hackers previously used a flaw in the software to attack targets in the education sector in May and June, according to Google's Threat Intelligence Group. But months later, the FBI contractor apparently still had not applied a security patch that was available for the software. "The inmate locator at the U.S. Bureau of Prisons website reports that a 54-year-old Edward Dubrovsky is currently being held at a federal facility in Philadelphia," reports security researcher Brian Krebs. Thanks to long-time Slashdot reader schwit1 for sharing the news.

On Thursday those trying to access the Ubuntu website, ISO downloads, and similar Ubuntu resources on Thursday found the site "inoperable," reports Phoronix, with the disruption confirmed as a distributed denial of service attack. "Our team is working diligently to resolve the incident," according to a Thursday post on Ubuntu Discourse - followed by a later announcement. "At this time our team continues to work on restoring affected services, most of them are now available. We appreciate your patience and understanding." Ubuntu's status page shows the Ubuntu.com outage lasting for 2 hours and 27 minutes on Friday - though with four-hour outages Wednesday (and other outages affecting other Ubuntu sites). Today "All components are Operational," the status page reports.

In this article. I am going to explain the different steps the I/O manager follows when initializing an I/O operation starting from determining the right target, choosing the right path and finally sending the request to be processed by the right drivers. To make it easier I choose to focus on read requests only since the major steps are common by all types of requests. ↫ Win-Ware A very in-depth look at Windows' I/O Manager.

At OSNews, we love us a hobby operating system project. I started a small experiment: writing a very basic kernel in Swift, and running on QEMU. The goal is obviously not to replace Linux or any other popular kernel, but just to have fun and understand what is required to make a program run without an operating system underneath it. Actually I made a similar experiment years before with arOS 10 years ago. For the moment, the kernel does only one thing: it prints a message through QEMU and then waits forever, which is enough for a first deep dive. ↫ Carette Antonin This is effectively a "hello world" kernel, as it doesn't actually do much else at this point. Still, there's a ton of details in the article for the aspiring kernel developers among you.

This is a story of how we got from something like this: Failed to deserialize BUILDINFO file: Parser failed with the following error: unknown ^ invalid makepkg build environment option expected `buildflags`, `ccache`, `check`, `color`, `distcc`, `sign`, `makeflags` To this: When the ALPM project started, the goal was fairly simple: Better tooling to interact with the low-level plumbing of Arch Linux Package Management (ALPM). This meant binaries to read/write individual file types, better error messages, extensive specifications and of course exports to common dataformats like JSON. The thing is, although some of us already had experience with low-level dataframe parsing, …

Whenever Microsoft starts messing with something like the search function in Windows, a lot of people are going to be holding their breath and expecting the worst. Well, get ready, because they're redesigning the whole thing. In July, we shared how we are improving the Windows Search Box with less clutter and more control. We introduced a calmer home screen, removed promotional content from web results, and gave you more choice over whether web and Microsoft Store suggestions appear. Today, we're carrying those investments forward with a new Windows Search experience built on WinUI 3. This modern foundation makes Windows Search faster and more efficient with resources, while delivering an even more streamlined and focused design. ↫ Anshul Rawat at the Windows Blogs The company claims this new version of search is faster and uses less memory, which, if true, are very welcome improvements. It's also just a single column of results now, and they're adding inline previews for things like weather and files on your machine, as well as for answers to all kinds of queries you might normally go to an online search engine for. You can now also use search to perform all kinds of tasks in Windows, like turning on dark mode, managing windows, and so on. All of this can be done using relatively natural language, and Microsoft claims they've implemented better detection of typing errors and synonyms, which is quite welcome. Weirdly enough, though, it's not yet integrated into the Start menu, since it's a preview just for testers, but that's something they're working on for future releases. Judging by the videos and screenshots, I'm actually kind of positively surprised. This looks quite decent and nice, and if the promised performance improvements actually materialise, this may actually be an upgrade to search worth looking forward to. Of course, this is still Microsoft, so it's just as likely they'll screw up somewhere between now and when this goes live to regular users. Still, I think it looks decent.

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which. Learning about alpm-hooks(5) and alpm-install-scriptlet(5) files …
