In anticipation of the launch of a new stream at the Data Engineer course, we prepared a translation of interesting material. Overview We'll talk about a fairly popular pattern whereby applications use multiple data stores, where each store is used for its own purposes, for example, to store the canonical form of data (MySQL, etc.), provide advanced search capabilities (ElasticSearch, etc.). etc.), caching (Memcached, etc.) […]
Hi all! This is my first post on Habré, I hope the community will be interested. In the Perm Linux Users Group, we saw a lack of review materials on free and open source news and decided that it would be nice to collect all the most interesting things every week so that after reading such a review, a person would be sure that he did not miss anything important. I prepared issue #0, […]
The whole point of modern surveillance is to differentiate between people so that everyone can be treated differently. Facial recognition technologies are only a small part of the system of total surveillance The author of the essay is Bruce Schneier, an American cryptographer, writer and information security specialist. Member of the board of directors of the International Association for Cryptological Research and member of the advisory board of the Electronic Privacy Information Center. The essay was published on January 20, 2020 in the blog […]
Most people strive to be perfect. No, not to be, but to seem. There is beauty all around, not the world. Especially now with social media. And he’s a handsome guy himself, and he works great, and he gets along with people, and he’s constantly developing, and he reads smart books, and he relaxes on the seas, and he solves problems on time, and he’s promising, and he watches the right films (so that the rating […]
I was inspired to write this article by a translation that described how, by focusing on facial recognition systems, we are missing the whole idea of mass data collection: a person can be identified using absolutely any data. Even people themselves use different methods to do this: for example, the brain of a nearsighted person relies on gait to identify people over long distances, rather than trying to recognize a face. […]
Having quite a lot of experience in the field of industrial automation, we are always in search of the best options to solve our problems. Depending on the customer’s technical specifications, we had to choose one or another hardware and software base. And if there were no strict requirements for installing Siemens equipment in conjunction with the TIA-portal, then, as a rule, the choice fell on […]
The Tiny Core team has announced the release of a new version of the lightweight distribution Tiny Core Linux 11.0. Fast operation of the OS is ensured by the fact that the system is completely loaded into memory, while requiring only 48 MB of RAM to operate. The innovation of version 11.0 is the transition to kernel 5.4.3 (instead of 4.19.10) and broader support for new hardware. Also updated busybox (1.13.1), glibc […]
All my adult life, I have been an energy drink (no, now we are not talking about a drink with dubious properties). I have never been particularly interested in the world of information technology, and I can hardly even multiply matrices on a piece of paper. And I never needed this, so that you understand a little about the specifics of my work, I can share a wonderful […]
A set of Cryptsetup 2.3 utilities has been released, designed to configure encryption of disk partitions in Linux using the dm-crypt module. Supports dm-crypt, LUKS, LUKS2, loop-AES and TrueCrypt partitions with VeraCrypt extensions. It also includes veritysetup and integritysetup utilities for configuring data integrity controls based on the dm-verity and dm-integrity modules. The key improvement in the new […]
An article has been published on the Hyperbola project's wiki, which discusses the problems of the Rust language in the context of software freedom, as well as the need for development independent of the trademark policies of the Mozilla Corporation (subsidiary of the Mozilla Foundation, annual income of about 0.5 billion dollars). One of the problems discussed in the article is the fact that, unlike C, Go, Haskell and […]
Andrey Konovalov from Google is developing a new USB Raw Gadget module that allows you to emulate USB devices in user space. An application for inclusion of this module in the main Linux kernel is under consideration. The USB Raw Gadget is already being used by Google to simplify fuzz testing of the USB kernel stack using the syzkaller toolkit. The module adds a new programming interface to the kernel subsystem […]
On February 11, Firefox 73.0 was released to the public. The Firefox developers would like to give special thanks to the 19 new first-time contributors who submitted code for this release. Added: ability to set the default zoom level globally (in the settings in the “Language and Appearance” section), while the zoom level for each site separately is still preserved; [windows] page background adjusts to [...]
