The Prossimo project (funded by the nonprofit Internet Security Research Group) seeks to "move the Internet's security-sensitive software infrastructure to memory safe code." Two years ago the Prossimo project made an announcement: they'd begun work on rav1d, a safer high performance AV1 decoder written in Rust, according to a new update:

We partnered with Immunant to do the engineering work. By September of 2024 rav1d was basically complete and we learned a lot during the process. Today rav1d works well — it passes all the same tests as the dav1d decoder it is based on, which is written in C. It's possible to build and run Chromium with it.
There's just one problem — it's not quite as fast as the C version...

Our Rust-based rav1d decoder is currently about 5% slower than the C-based dav1d decoder (the exact amount differs a bit depending on the benchmark, input, and platform). This is enough of a difference to be a problem for potential adopters, and, frankly, it just bothers us. The development team worked hard to get it to performance parity. We brought in a couple of other contractors who have experience with optimizing things like this. We wrote about the optimization work we did. However, we were still unable to get to performance parity and, to be frank again, we aren't really sure what to do next.

After racking our brains for options, we decided to offer a bounty pool of $20,000 for getting rav1d to performance parity with dav1d. Hopefully folks out there can help get rav1d performance advanced to where it needs to be, and ideally we and the Rust community will also learn something about how Rust performance stacks up against C.

This drew a snarky response from FFmpeg, the framework that powers audio and video processing for everyone from VLC to Twitch. "Rust is so good you can get paid $20k to make it as fast as C," they posted to their 68,300 followers on X.com.

Thanks to the It's FOSS blog for spotting the announcement.

[>] When a Company Does Job Interviews with a Malfunctioning AI - and Then Rejects You

IBM laid off "a couple hundred" HR workers and replaced them with AI agents. "It's becoming a huge thing," says Mike Peditto, a Chicago-area consultant with 15 years of experience advising companies on hiring practices. He tells Slate "I do think we're heading to where this will be pretty commonplace."

Although A.I. job interviews have been happening since at least 2023, the trend has received a surge of attention in recent weeks thanks to several viral TikTok videos in which users share videos of their A.I. bots glitching. Although some of the videos were fakes posted by a creator whose bio warns that his content is "all satire," some are authentic — like that of Kendiana Colin, a 20-year-old student at Ohio State University who had to interact with an A.I. bot after she applied for a summer job at a stretching studio outside Columbus. In a clip she posted online earlier this month, Colin can be seen conducting a video interview with a smiling white brunette named Alex, who can't seem to stop saying the phrase "vertical-bar Pilates" in an endless loop...

Representatives at Apriora, the startup company founded in 2023 whose software Colin was forced to engage with, did not respond to a request for comment. But founder Aaron Wang told Forbes last year that the software allowed companies to screen more talent for less money... (Apriora's website claims that the technology can help companies "hire 87 percent faster" and "interview 93 percent cheaper," but it's not clear where those stats come from or what they actually mean.)

Colin (first interviewed by 404 Media) calls the experience dehumanizing — wondering why they were told dress professionally, since "They had me going the extra mile just to talk to a robot." And after the interview, the robot — and the company — then ghosted them with no future contact. "It was very disrespectful and a waste of time."

Houston resident Leo Humphries also "donned a suit and tie in anticipation for an interview" in which the virtual recruiter immediately got stuck repeating the same phrase.
Although Humphries tried in vain to alert the bot that it was broken, the interview ended only when the A.I. program thanked him for "answering the questions" and offering "great information" — despite his not being able to provide a single response. In a subsequent video, Humphries said that within an hour he had received an email, addressed to someone else, that thanked him for sharing his "wonderful energy and personality" but let him know that the company would be moving forward with other candidates.

[>] Why Two Amazon Drones Crashed at a Test Facility in a December

While Amazon won FAA approval to fly beyond an operators' visual line of sight, "the program remains a work in progress," reports Bloomberg:

A pair of Amazon.com Inc. package delivery drones were flying through a light rain in mid-December when, within minutes of one another, they both committed robot suicide... [S]ome 217 feet (66 meters) in the air [at a drone testing facility], the aircraft cut power to its six propellers, fell to the ground and was destroyed. Four minutes later and 183 feet over the taxiway, a second Prime Air drone did the same thing.

Not long after the incidents, Amazon paused its experimental drone flights to tweak the aircraft software but said the crashes weren't the "primary reason" for halting the program. Now, five months after the twin crashes, a more detailed explanation of what happened is starting to emerge. Faulty readings from lidar sensors made the drones think they had landed, prompting the software to shut down the propellers, according to National Transportation Safety Board documents reviewed by Bloomberg. The sensors failed after a software update made them more susceptible to being confused by rain, the NTSB said.

Amazon also removed a backup sensor present that had been present on earlier iterations, according to the article — though an Amazon spokesperson said the company had found ways to replicate the removed sensors.

But Bloomberg notes Amazon's drone efforts has faced "technical challenges and crashes, including one in 2021 that set a field ablaze at the company's testing facility in Pendleton, Oregon."

Deliveries are currently limited to College Station, Texas, and greater Phoenix, with plans to expand to Kansas City, Missouri, the Dallas area and San Antonio, as well as the UK and Italy. Starting with a craft that looked like a hobbyist drone — and was vulnerable to even modest gusts of wind — Amazon went through dozens of designs to toughen the vehicle and ultimately make it capable of carting about 5 pounds, giving it the capability to transport items typically ordered from its warehouses. Engineers settled on a six-propeller design that takes off vertically before cruising like a plane. The first model to make regular customer deliveries, the MK27, was succeeded last year by the MK30, which flies at about 67 miles an hour and can deliver packages up to 7.5 miles from its launch point. The craft takes off, flies and lands autonomously.

[>] 'The People Stuck Using Ancient Windows Computers'

The BBC visits "the strange, stubborn world of obsolete Windows machines."

Even if you're a diehard Apple user, you're probably interacting with Windows systems on a regular basis. When you're pulling cash out, for example, chances are you're using a computer that's downright geriatric by technology standards. (Microsoft declined to comment for this article.) "Many ATMs still operate on legacy Windows systems, including Windows XP and even Windows NT," which launched in 1993, says Elvis Montiero, an ATM field technician based in Newark, New Jersey in the US. "The challenge with upgrading these machines lies in the high costs associated with hardware compatibility, regulatory compliance and the need to rewrite proprietary ATM software," he says. Microsoft ended official support for Windows XP in 2014, but Montiero says many ATMs still rely on these primordial systems thanks to their reliability, stability and integration with banking infrastructure.

And a job listing for an IT systems administrator for Germany's railway service "were expected to have expertise with Windows 3.11 and MS-DOS — systems released 32 and 44 years ago, respectively. In certain parts of Germany, commuting depends on operating systems that are older than many passengers."
It's not just German transit, either. The trains in San Francisco's Muni Metro light railway, for example, won't start up in the morning until someone sticks a floppy disk into the computer that loads DOS software on the railway's Automatic Train Control System (ATCS). Last year, the San Francisco Municipal Transit Authority (SFMTA) announced its plans to retire this system over the coming decade, but today the floppy disks live on.

Apple is "really aggressive about deprecating old products," M. Scott Ford, a software developer who specialises in updating legacy systems, tells the BBC. "But Microsoft took the approach of letting organisations leverage the hardware they already have and chasing them for software licenses instead. They also tend to have a really long window for supporting that software."
And so you get things like two enormous LightJet printers in San Diego powered by servers running Windows 2000, says photographic printer John Watts:

Long out of production, the few remaining LightJets rely on the Windows operating systems that were around when these printers were sold. "A while back we looked into upgrading one of the computers to Windows Vista. By the time we added up the money it would take to buy new licenses for all the software it was going to cost $50,000 or $60,000 [£38,000 to £45,000]," Watts says. "I can't stand Windows machines," he says, "but I'm stuck with them...."

In some cases, however, old computers are a labour of love. In the US, Dene Grigar, director of the Electronic Literature Lab at Washington State University, Vancouver, spends her days in a room full of vintage (and fully functional) computers dating back to 1977... She's not just interested in early, experimental e-books. Her laboratory collects everything from video games to Instagram zines.... Grigar's Electronic Literature Lab maintains 61 computers to showcase the hundreds of electronic works and thousands of files in the collection, which she keeps in pristine condition.

Grigar says they're still looking for a PC that reads five-and-a-quarter-inch floppy disks.
