Andrei Konovalov from Google discovered 15 vulnerabilities in USB drivers provided in the Linux kernel. This is the second batch of issues found during fuzz testing — in 2017, this researcher discovered another 14 vulnerabilities in the USB stack. These issues could potentially be exploited when connecting specially crafted USB devices to a computer. An attack is possible with physical access to the hardware and […]
A vulnerability (CVE-2019-5611) has been fixed in FreeBSD that allows the kernel to crash (packet-of-death) via specially fragmented ICMPv6 MLD (Multicast Listener Discovery) packets. The problem is caused by a lack of necessary checking in the m_pulldown() call, which can lead to the return of non-continuous mbuf chains, contrary to the caller's expectations. The vulnerability has been fixed in updates 12.0-RELEASE-p10, 11.3-RELEASE-p3, and 11.2-RELEASE-p14. As a workaround to protect, you can […]
Futhark is a programming language that supports parallelism and belongs to the ML family. Added: The internal representation of parallel constructs has been revised and optimized. With few exceptions, this may significantly impact performance. There is now support for structurally typed sum types and pattern matching. However, there are still some issues with sum-type arrays that contain arrays themselves. Compilation time has been significantly reduced […]
1. The cost of a labeling machine for weight products is comparable to the cost of implementing an MES system project. For simplicity, let’s assume that both cost 7 million rubles. 2. The payback period for labeling lines is fairly easy to calculate, making it clear who bears the costs: A team of 4 labelers labels approximately 5 tons per shift; with an automated line, supported by 3 […]
Moderator's comment. This article was in the Sandbox and was rejected during pre-moderation. However, an important and complex question was raised in the article today. This post reveals signs of personality disintegration and may be useful to those who, as the author of the mentioned article put it, are a meter from the waterfall. Therefore, it was decided to publish it. Hello, dear readers! I am writing to you in a state of […]
This is a complex, controversial, and painful topic. But I want to try to discuss it. I can't share anything great and brilliant about myself, so I will refer to the quite sincere (amidst a lot of hypocrisy and moralizing on this issue) speech of mathematician, Doctor of Sciences, Alexey Savvateev. (The video itself is at the end of the post.) 36 years of my life have been closely associated with alcohol. […]
Translator’s note: The author of this material is Cindy Sridharan, an engineer from imgix, focusing on API development and, in particular, microservices testing. In this material, she shares her comprehensive vision of current issues in distributed tracing, where, in her opinion, there is a lack of truly effective tools to solve pressing challenges. [The illustration is borrowed from another material on distributed […]
The ICR-3200 series routers are designed to replace the classic combination of a single-board computer + modem + router. Now, you can run all necessary logic directly on the router. Thanks to the powerful ARM processor, 512 MB of RAM, and ~2GB of built-in flash memory, you can even run a nodejs server on the router! Serial interfaces RS-232/485 are also built into the router and are available directly in the operating system with full […]
In 2020, rumors suggested that Microsoft would replace the classic Edge browser that comes with Windows 10 with a new one based on Chromium. Now, the software giant is one step closer to this: Microsoft has released a public beta version of its new Edge browser. It is available for all supported platforms: Windows 7, Windows 8.1, and Windows 10, as well as for […]
IBM has announced the transition of the Power instruction set architecture (ISA) to an open standard. In 2013, IBM already established the OpenPOWER consortium, which granted the ability to license intellectual property related to POWER and provided complete access to the specifications. However, licensing fees for chip manufacturing continued to be collected. From now on, the creation of custom chip modifications […]
The first release of the notqmail project has been introduced, marking the development of a fork of the qmail mail server. Qmail was created by Daniel J. Bernstein in 1995 to provide a more secure and faster alternative to sendmail. The last release of qmail 1.03 was published in 1998, and since then, there have been no official updates, but the server remains an example […]
Three years ago, I published my first and only article on habr.ru, which was dedicated to writing a small application using Angular 2. At that time, it was in beta, there were few tutorials available, and I found it interesting in terms of entry time compared to other frameworks/libraries from a non-programmer's perspective. In that article, I mentioned that […]
