  • Google open-sources gesture tracking AI for mobile devices

    Real-time hand shape and motion trackers are an invaluable part of sign language recognition and gesture control systems, not to mention a number of augmented reality experiences. But they’re often hobbled by occlusion and a lack of contrast patterns, preventing them from performing reliably or robustly. Those challenges and others motivated scientists at Google to investigate a new computer vision approach to hand perception — one bolstered by machine learning. They say that in experiments, it managed to infer up to 21 3D points of a hand (or multiple hands) on a mobile phone from just a single frame.

Open Source platforms to now help students

The technical institutes in the State are now asked to use free and open-source software developed by a team, headed by the Ministry of Human Resource Development (MHRD). The MHRD has also promoted their FOSSEE (Free and Open Source Software for Education) projects which uses tools so that students can easily use them. Recently, the MHRD made a decision that FOSSEE should be promoted amongst the student community so they can aim at reducing dependency on proprietary software in educational institutions. The MHRD Minister Ramesh Pokhriyal Nishank too took to twitter urging students to use FLOSS tools in various languages to meet academic and research requirements. Read more

  • A guided tour of Linux file system types

    While it may not be obvious to the casual user, Linux file systems have evolved significantly over the last decade or so to make them more resistant to corruption and performance problems. Most Linux systems today use a file system type called ext4. The “ext” part stands for “extended” and the 4 indicates that this is the 4th generation of this file system type. Features added over time include the ability to provide increasingly larger file systems (currently as large as 1,000,000 TiB) and much larger files (up to 16 TiB), more resistance to system crashes and less fragmentation (scattering single files as chunks in multiple locations) which improves performance.

Ghidra is a framework developed by the NSA’s Research Directorate for the agency’s cybersecurity mission. It’s designed to analyze malicious code to give security pros a better understanding of potential vulnerabilities in their networks and systems.

  • Linux Is Being Hit with Zero-Day Exploits/ Zero-Day Attacks [Ed: This is not news. If you have a system that is unpatched for months, despite many warnings, it is a risk, no matter the OS/kernel.]

    It was once the popular opinion that Linux was immune to zero-day exploits. However, even before the Equifax exploit, vulnerabilities were found in Linux distributions like Fedora and Ubuntu. In particular, back in 2016, a security researcher discovered that you could exploit a Linux system by playing a specific music file. Then, in 2017, a group of attackers used Struckshock vulnerability to carry on the attack on Equifax. These zero-day attacks are Advanced Persistent Attacks that exploit recently discovered vulnerabilities. Read on to learn more about what are zero-day exploits and how they can affect a Linux system.

  • Intel, Google, Microsoft, and others launch Confidential Computing Consortium for data security

    Major tech companies including Alibaba, Arm, Baidu, IBM, Intel, Google Cloud, Microsoft, and Red Hat today announced intent to form the Confidential Computing Consortium to improve security for data in use. Established by the Linux Foundation, the organization plans to bring together hardware vendors, developers, open source experts, and others to promote the use of confidential computing, advance common open source standards, and better protect data. “Confidential computing focuses on securing data in use. Current approaches to securing data often address data at rest (storage) and in transit (network), but encrypting data in use is possibly the most challenging step to providing a fully encrypted lifecycle for sensitive data,” the Linux Foundation said today in a joint statement. “Confidential computing will enable encrypted data to be processed in memory without exposing it to the rest of the system and reduce exposure for sensitive data and provide greater control and transparency for users.”
