The kinetic energy of the Sapsan at maximum speed exceeds 1500 megajoules. To come to a complete stop, all of it must be dissipated by the braking systems. I was asked to elaborate on this topic right here on Habr. There are quite a few overview articles published on railway topics, but this particular theme has not yet been covered in detail. I think it would be quite interesting […]
I see that the first, historical part of my narrative was well received by the audience, so there's no reason not to continue. High-speed trains, like the TGV, no longer rely on pneumatic braking. Today we will talk about modern times, specifically about the approaches used in the 21st century to create braking systems for rolling stock, which will soon be celebrating its third decade. 1. Classification of brakes […]
The CAINE 11.0 (Computer Aided INvestigative Environment) release has been unveiled. This specialized live distribution is designed for conducting forensic analysis, searching for hidden and deleted data on disks, and uncovering residual information to reconstruct the breach of the system. The distribution is based on Ubuntu and features a unified graphical interface built on the MATE shell to manage a variety of utilities for exploring both Unix and Windows […]
On November 19, Football Manager 2020 was released and, according to GamesIndustry, immediately topped the EMEAA weekly chart, surpassing Star Wars Jedi: Fallen Order and Call of Duty: Modern Warfare. In the second week since its release, Star Wars Jedi: Fallen Order is holding its second position, while Call of Duty: Modern Warfare has dropped to fourth place [...]
Hello, Habr! Like last year, the Hosting Cafe team has prepared a collection of discounts from hosts for this Black Friday, sorted in descending order of discount percentage. Inferno.name — Up to 99% off on dedicated servers and VPS. Namecheap.com — Up to 98% off on domain registrations, hosting, email hosting, and SSL certificates. Hyperhost.ua — 90% off [...]
"Why not create another collection of discounts for Black Friday in the hosting sector," I thought... and I did. Collections from past years are here and here. Host4.biz — 90% off on virtual or VIP hosting, 50% off on Linux VPS. Hyperhost.ua — 90% off on virtual hosting, 30% off on virtual servers. Ntup.net — 90% off on virtual and [...]
Translator's note: This excellent material from Okta clearly and simply explains the principles of how OAuth and OIDC (OpenID Connect) work. This knowledge will be useful for developers, system administrators, and even "regular users" of popular web applications, who are likely also exchanging confidential data with other services. In the "stone age" of the internet, sharing information between services was easy. You just [...]
The MAT2 0.10.0 utility has been released, designed for removing metadata from files in various formats. The program addresses the issue of residual data remaining in documents and multimedia files, which may be perceived as undesirable for disclosure. For example, photographs may retain data about location, time of capture, and device used, while edited images may contain information about the operating system and the programs used [...].
Jeremy Soller, the founder of the Redox operating system written in Rust, spoke about the successful use of Redox on the System76 Galaga Pro laptop (Jeremy Soller works at System76). Fully functional components include the keyboard, touchpad, storage (NVMe), and Ethernet. Experiments with Redox on the laptop have already improved driver performance and provided HiDPI support for some […]
Traditionally, the 'ten' uses version numbers that are direct indicators of release dates. Although they often differ from actual dates, this approach allows for a fairly accurate estimation of when a particular version will be released. For instance, version 1809 was scheduled for September 2018 but was released in October. Windows 10 (1903) corresponds to March and May 2019, respectively. The same […]
Microsoft officially ceased to provide the option for free upgrades from Windows 7 and Windows 8.1 to Windows 10 in December 2017. Despite this, reports have surfaced online that some users with a legitimate copy of Windows 7 or Windows 8.1 are still able to perform a free upgrade to Windows 10. It’s worth noting […]
Enthusiast Jay Doscher developed the Raspberry Pi Recovery Kit, which theoretically is capable of surviving the end of the world while remaining fully operational. Jay took available electronic components and encased them in a protected waterproof housing impervious to physical damage. There’s also a copper foil casing to shield against electromagnetic radiation. Some components were printed using a 3D printer. […]
