An anonymous reader writes: Facebook unveiled a new compression technique they call ‘Superpack compression.’ In a blog post written by software engineer Sapan Bhatia, they claim that their compression improves Android app size by 20% over the default Zip compression used by Android. The post gives an overview of the compression ideas. The basis of these ideas is called out to be a key insight in Kolmogorov Complexity, that any data can be represented in the form of programs that generate that data. Facebook’s tool, Superpack, mines out such small programs and optimizes them using compiler techniques.

Microscopy is essential to many areas of science. We use it to look at everything from the small devices we fabricate to the tiny structures inside cells. And microscopy wouldn’t function without input from many areas of science. Chemistry helps with stains, dyes, and sample preparation. Physics determines what’s possible with different forms of optics. And fields like biology and geology tell us which samples can give us valuable information. Combined, these tools give us a nearly infinite suite of options for looking at the world of the small.
With the right choices among those options, a microscope can do far more than just advance science; it can create objects of art. Each year, when Nikon releases the results of its annual microscopy competition, we struggle for new superlatives to describe the images. This year is no exception. So rather than struggling with words, we’ll get straight to the images.
The rock. We tend to think of microscopes as examining living matter, revealing details that are critical to understanding cells and the organisms built from them. But chemicals and minerals also have details that aren’t always visible to the naked eye and can be critical to their behavior as well. We’ve always loved close-ups of crystals and rocks, and this year’s collection of images contains a surfeit of them.

IT executives see the talent shortage as the most significant adoption barrier to 64% of emerging technologies, according to a new Gartner survey. From a report: Across compute infrastructure and platform services, network, security, digital workplace, IT automation, and storage and database, respondents cited a lack of qualified candidates as a leading factor impeding tech deployment at their companies. “The ongoing push toward remote work and the acceleration of hiring plans in 2021 has exacerbated IT talent scarcity, especially for sourcing skills that enable cloud and edge, automation, and continuous delivery,” Gartner research VP Yinuo Geng said in a press release.
“As one example, of all the IT automation technologies profiled in the survey, only 20% of them have moved ahead in the adoption cycle since 2020. The issue of talent is to blame here.” The talent gaps are particularly acute for IT automation and digital workplace solutions, according to the executives surveyed — a reflection of the demand for these technologies. According to McKinsey, nearly half of executives say their embrace of automation has accelerated, while digital and technology adoption is taking place about 25 times faster than before the pandemic. For example, Brain Corp reported that the use of robots to clean retail stores in the U.S. rose 24% in Q2 2020 year-over-year, and IBM has seen a surge in new users of its AI-driven customer service platform Watson Assistant.

GPU driver releases normally aren’t very newsworthy; they usually fix bugs, boost performance in some games, and add support for new GPUs. But owners of last-generation AMD Radeon RX 5000-series graphics cards should take note of today’s Adrenalin 21.9.1 release. This update adds support for AMD’s “Smart Access Memory” (SAM) feature for older GPUs. AMD says the feature can improve game performance by up to 15 percent in some games.
SAM support was previously restricted to the Radeon RX 6800 series (and Nvidia’s GeForce RTX 3000 series, which support a mostly identical feature that Nvidia calls Resizable BAR). In addition to the right GPU and the right drivers, you’ll also need to be running a supported processor on a supported chipset: either a 10th- or 11th-generation Intel Core CPU in a 400- or 500-series motherboard or a Ryzen 3000 or 5000-series CPU in a 400- or 500-series motherboard.
Whether you’re talking about SAM or Resizable BAR, the different names all refer to the same PCI Express functionality. Normally, your computer’s processor can only directly access 256MB of your GPU’s video memory at a time, and the memory requires larger assets to be broken up into smaller chunks for transfer. Resizable BAR removes that limit and noticeably improves performance in some games. A TechSpot test of 36 games using an RX 6800 GPU and Ryzen 5950X processor observed an improvement of up to 20 percent depending on the game and the settings. For most games, though, performance improved by a much smaller amount or didn’t improve at all. A few games even showed performance decreases with SAM enabled, though never by enough to make any games unplayable.

Coming almost two months after LibreOffice 7.1.5, the LibreOffice 7.1.6 update is here to fix more bugs across all core components of the open-source software suite used by millions of users worldwide on GNU/Linux, macOS, and Windows platforms. A total of 44 bugs were squashed, according to the changelogs from RC1 and RC2.
LibreOffice 7.2 is already here as the next major release of the popular and free office suite, but you are probably still using the LibreOffice 7.1 series on your GNU/Linux distribution, so I suggest you keep an eye on the stable software repositories for the 7.1.6 release and update as soon as it’s available.

Today, Apple released new versions of its iOS and iPadOS 14, macOS Big Sur, and watchOS 7 operating systems. The updates hit just one day before Apple is expected to reveal its new iPhone and Apple Watch models and the release dates for iOS 15 and watchOS 8.
These updates are security-related across the board, and they add no new features or functionality at all.
Specifically, two main issues have been addressed across Apple’s platforms, one with Core Graphics and the other with WebKit. In both cases, maliciously crafted content (PDFs or web content) could be used for arbitrary code execution. Apple also says these updates fix an issue that allowed attackers to bypass Apple protections intended to stop code execution via Messages.

The biggest new feature of the new Steam Client update is a brand new downloads page that’s easier to use and has a new design. The new download page now displays the total progress, including disk allocation process, when downloading or updating a game, as well as a faded progress bar and percent completed for partially completed downloads or updates.
In addition, the new downloads page will now display a new icon next to a game’s title with a tooltip showing the type of content included in the update (e.g. Downloadable Content, Game Content, Shader Pre-caching, or Workshop Content). Moreover, users will now be able to re-order the download queue using drag and drop, as well as to launch a game or suspend download throttling from the context menu of the actively downloading game.

Facebook had a problem on its hands. People were making posts that got caught in the company’s automated moderation system or were taken down by its human moderators. The problem wasn’t that the moderators, human or otherwise, were wrong to take down the posts. No, the problem was that the people behind the posts were famous or noteworthy, and the company didn’t want a PR mess on its hands.
So Facebook came up with a program called XCheck, or cross check, which in many instances became a de facto whitelist. Over the years, XCheck has allowed celebrities, politicians, athletes, activists, journalists, and even the owners of “animal influencers” like “Doug the Pug” to post whatever they want, with few to no consequences for violating the company’s rules.
“For a select few members of our community, we are not enforcing our policies and standards,” reads an internal Facebook report published as part of a Wall Street Journal investigation. “Unlike the rest of our community, these people can violate our standards without any consequences.”

Apple has released security updates for a newly discovered zero-day vulnerability that affects every iPhone, iPad, Mac and Apple Watch. Citizen Lab, which discovered the vulnerability and was credited with the find, urges users to immediately update their devices. From a report: The technology giant said iOS 14.8 for iPhones and iPads, as well as new updates for Apple Watch and macOS, will fix at least one vulnerability that it said “may have been actively exploited.” Citizen Lab said it has now discovered new artifacts of the ForcedEntry vulnerability, details it first revealed in August as part of an investigation into the use of a zero-day vulnerability that was used to silently hack into iPhones belonging to at least one Bahraini activist.
Last month, Citizen Lab said the zero day flaw — named as such since it gives companies zero days to roll out a fix — took advantage of a flaw in Apple’s iMessage, which was exploited to push the Pegasus spyware, developed by Israeli firm NSO Group, to the activist’s phone. Pegasus gives its government customers near-complete access to a target’s device, including their personal data, photos, messages and location.
