'Tutor' Who Took Online Tests for 124 Students Jailed for Three Years

A private tutor who charged money to take dozens of exams for students and submit coursework for them "has been jailed for three years," reports the BBC, "after his scam earned him £300,000." Shahid Adnan completed assignments and online tests for more than 120 students at Liverpool John Moore's University, the Crown Prosecution Service said. The 43-year-old, of Lysander Close, Liverpool, was caught in February 2023 after a student handed in a USB drive containing suspicious coursework to Dr Tom Berry of the university's school of computer science and mathematics. Berry's checks revealed the drive was used by Adnan with documents linked to a company he set up called Study Sharp Ltd. Excel spreadsheets containing details of other students, their study modules, coursework due dates, and their personal login credentials were also found. Further checks confirmed suspicions that Adnan was accessing the university's network to submit fraudulent work and sit examinations on behalf of students... [I]nvestigations led police to believe Adnan may have been doing work for 124 students at universities all over the world. The BBC also interviewed detective sergeant Adam Dagnall from Merseyside Police's cybercrime unit, who said Adnan was living a lavish lifestyle "well beyond" his stated occupations as a private tutor and Amazon delivery driver. His bank accounts held more than £2m ($2,645,100 USD).

TikTok Shows 3x More AI Slop Than YouTube, Report Finds

"About 59% of TikTok videos served to a new account's For You feed are AI slop," writes Search Engine Journal, "according to a report from Kapwing, the video creation tool company. That's roughly three times the rate Kapwing found on YouTube." The company manually reviewed over 10,000 TikTok videos across 20 categories and ran a separate fresh-account test, counting AI-generated content in the first 500 For You videos. Kapwing ran the same fresh-account test on YouTube and found that 104 of the first 500 Shorts, or 21%, were AI slop. On TikTok, 294 of 500 For You videos hit that threshold... Of the 2,000 videos Kapwing reviewed in TikTok's Kids category, 57% were AI slop. That was the highest rate of any category in the analysis. The highest-rate tag was #cartoonkids, where 97 of 100 featured videos were AI-generated. Tags like #cartoons and #babysong both reached 83%, and #forkids came in at 79%. After Kids, the next highest AI slop rates were in Science and Education (35%), Health (33%), and History (33%). All three are categories where visual illustration and voiceover narration make up much of the content. On the other end, categories where on-camera presence or physical demonstration are central had the lowest rates. Fashion came in at 1.3%, Music at 1.5%, and Fitness at 1.6%. The article notes that by last November, TikTok "had already labeled 1.3 billion videos as AI-generated, according to the report."

Someone Forked systemd Over Its New Birth Date Field

The blog Linuxiac reports: A new systemd fork has appeared with a specific purpose: removing systemd's recently added support for storing a user's birth date in JSON user records. The fork, called Liberated systemd, published its first tagged release as v261 shortly after the official systemd 261 release. In other words, the fork follows upstream systemd while reverting the change that added the new optional birthDate field. Importantly, this is not a new init system, a wider redesign of systemd, or a general-purpose alternative to the upstream project. Its stated purpose is to remain close to upstream systemd while removing what the author describes as "surveillance enablement"... The author recommends testing the fork in a virtual machine before using it on real hardware and warns nightly builds are more likely to be unstable than named releases.

A tale of two path separators

In macOS, you can apparently create files and directories in the Finder with names that include slashes. If you then go into the terminal and take a look with ls, you'll see that the slashes are actually colons. I don't understand all the nuances, but I know this is a side-effect of the fact that macOS has not one but two path separators: the slash (/) and the colon (:). The two separators are used in different contexts, and the system will translate between them as needed. These two separators reflect the two parent systems of modern macOS: classic Mac OS and the Unix-like NeXTSTEP. When they were joined together, Apple's engineers had to build a file system that was compatible with both the classic Mac's file system (the Mac OS Extended File System, aka HFS+), and with NeXTSTEP's file system (the Unix file system, aka UFS). Among other differences, these systems had different path separators: HFS+ used a colon, while UFS used a slash. ↫ Alex Chan (article from 2021) I had no idea macOS worked this way, but it makes sense considering the platform's dual history. What's interesting is that when Apple moved to APFS almost a decade ago, this duality in path separators remained, most likely for backwards compatibility reasons. In a sense, this is somewhat similar to Windows supporting both backward and forward slashes, with the former being a leftover from DOS, and the latter an addition (to Windows) from the UNIX world. None of that beats Windows when using the Japanese or Korean locale, though. Because Japanese and Korean Windows use different codepages than Windows in the Americas and Western Europe, these versions of Windows render the backslash as the yen sign (¥) and and won (₩) sign respectively. As such, something like the Program Files directory actually renders like C:¥Program Files¥ and C:₩Program Files₩. Similar issues occurred in other Windows locales as well, but the impact of this in Japan and South Korea were so widespread that people just expect it to be that way, even if it's easily fixed today. I can't find if Windows 11 still uses ¥/₩ in Japan/South Korea, since the last references of it I can quickly uncover all point to Windows 10.

Apple internals: Swift in the kernel

Apple's Swift has become the de-facto language for Apple's own developers for a while now, and it seems that with the new operating system releases from the company unveiled during WWDC, Switch is now also being used in the kernel. Naturally I dropped what I was doing and went grepping through the iOS 27 kernelcache. Alas, nothing came of it. All is not lost though: I found the Embedded Swift runtime in macOS 27, sitting in com.apple.kec.pthread of all places. Then I went poking around the root filesystem and it turns out Apple gave the whole effort a name: KernelKit. Let's dissect it. ↫ Josh Maine It's still quite limited at this time, which makes sense - you don't want to be too crazy with the core of the operating system that runs on god knows how many PCs, smartphones, and other devices. It's also entirely contained within a few kexts as embedded runtimes, and the XNU kernel itself remains entirely C and C++.

“I stored a website in a favicon”

Every website has a favicon. It's that little icon in your browser tab. Usually you upload it once and then never think about it again. But. A favicon is just an image. An image is just pixels. And pixels are just bytes. So of course I wondered if I could store something inside one. ↫ Tim Wehrle I love it when people do something useless just for fun.
