"Puppy Eyes": 30,000 Years of Dog-Human Coevolution

Posted on

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 […]

Reducing energy consumption in data centers — a new photon chip will help

Posted on

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 […]

NASA's Internal Network Breach via Raspberry Pi

Posted on

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 […]

OpenSSH has added protection against side-channel attacks

Posted on

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, […

E-books and their formats: DjVu — its history, advantages, disadvantages, and features

Posted on

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 […]

Overconfident NAS

Posted on

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, […]

Why is the Internet still online?

Posted on

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 […]

The VKHR project is developing a real-time hair rendering system.

Posted on

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 […]

A mode for blocking social media widgets and Firefox Proxy is being developed for Firefox.

Posted on

Mozilla developers have published mockups of upcoming improvements to interface elements related to protecting confidential data and blocking tracking of movements. Among the innovations is a new option for blocking social media widgets that track users' movements on external sites (for example, the Like buttons from Facebook and message embeds from Twitter). For authentication forms through social media accounts, the option is provided to […]
