The signal that helps airplanes find the runway can be faked using a radio for $600. The aircraft in the demonstration attacks the radio because of fake KGS signals, landing to the right of the runway. Almost any aircraft that has taken to the skies in the last 50 years—whether it’s a single-engine Cessna or a giant airliner with 600 seats—has relied on radio stations […]
Purism, the company developing the Librem 5 smartphone and the free distribution PureOS, has announced the release of the libhandy library 0.0.10, which includes a set of widgets and objects for creating user interfaces for mobile devices using GTK and GNOME technologies. The library is being developed as part of the effort to port GNOME applications for the Librem 5 smartphone environment. The project code is released under the GPL license […]
Dogs are very unusual creatures. They never inquire about your mood; they don’t care if you are rich or poor, foolish or wise, a sinner or a saint. You are their friend. That is enough for them. These words belong to the writer Jerome K. Jerome, known to many of us from the book 'Three Men in a Boat, Not Counting the Dog' and […]
MIT has developed an architecture for a new photonic processor. It will increase the efficiency of optical neural networks by a thousand times compared to similar devices. The chip will reduce the amount of electricity consumed by data centers. Here’s an overview of its structure. Photo — Ildefonso Polo — Unsplash Why a New Architecture is Needed Optical neural networks operate faster than traditional solutions that use electronic components. Light does not require isolation of signal […]
The National Aeronautics and Space Administration (NASA) has revealed information about a breach of its internal infrastructure that went undetected for nearly a year. Notably, the network was isolated from external threats, and the breach occurred internally via a Raspberry Pi board that was connected without authorization at the Jet Propulsion Laboratory. This board was used by staff as an entry point into the local […]
An experimental release of the open implementation of Win32 API — Wine 4.11 is now available. Since the release of version 4.10, 17 bug reports have been closed and 370 changes have been made. The most significant changes include: continuation of work on the DLL assembly by default with the built-in msvcrt library (provided by the Wine project, not the DLL from Windows) in PE (Portable Executable) format. Compared to […]
Damien Miller (djm @) has added an improvement to OpenSSH aimed at enhancing protection against various side-channel attacks, such as Spectre, Meltdown, RowHammer, and RAMBleed. The added protection is designed to prevent the recovery of private keys residing in memory by exploiting data leaks through side channels. The essence of the protection is that private keys, during moments of inactivity, […
Earlier on the blog, we wrote about the emergence of ebook formats DjVu and FB2. Today's topic is EPUB. Image: Nathan Oakley / CC BY History of the Format In the 90s, proprietary solutions dominated the ebook market, with many e-reader manufacturers developing their own formats. For instance, NuvoMedia used files with the .rb extension. This […]
In the early 1970s, American writer Michael Hart gained unrestricted access to a Xerox Sigma 5 computer at the University of Illinois. To make good use of the machine's resources, he decided to create the first electronic book by reprinting the U.S. Declaration of Independence. Today, digital literature has become widespread, largely due to the proliferation of portable devices (smartphones, e-readers, laptops). This […]
A tale was quickly told, but the work took a long time. More than a year and a half ago, I wanted to assemble my own NAS, and the starting point for building the NAS was organizing the server room. While sorting through cables, cases, and relocating a vintage 24-inch HP monitor to the dump, I discovered a cooler from Noctua. After considerable effort, […]
The Internet seems to be a strong, independent, and indestructible structure. In theory, the strength of the network is sufficient to withstand a nuclear explosion. In reality, the Internet can be brought down by a single small router. This is because the Internet is a jumble of contradictions, vulnerabilities, mistakes, and cat videos. The foundation of the Internet, the BGP protocol, is full of issues. It's surprising that it's still functioning. Beyond the flaws inherent in the Internet itself, it's also being broken by everyone […]
As part of the VKHR (Vulkan Hair Renderer) project, supported by AMD and RTG Game Engineering, a realistic hair rendering system is being developed using the Vulkan graphics API. The system supports real-time rendering when modeling hairstyles composed of hundreds of thousands of strands and millions of linear segments. By varying the level of detail, it allows for adjustments between performance and […]
