Later, the app was renamed to Firefox Lite, and now the developers have introduced a new version of the software product. The browser is called Firefox Lite 2.0, and it has all […]
Hello, Habr. In the first part, I explored 5 ways to use Raspberry Pi.

Photo from learn.adafruit.com As in the previous part, I will consider those methods that do not require programming. For those interested, the continuation is below. […]
It was the year 2019. Our laboratory received a rather unusual hard drive for our time, the QUANTUM FIREBALL Plus KA with a capacity of 9.1GB. According to the owner, the failure occurred back in 2004 due to a malfunctioning power supply, which took the hard drive and other PC components with it. What followed were visits to various service centers […]
TL; DR: JSONB can greatly simplify database schema development without compromising query performance. Introduction Let's provide a classic example, probably one of the oldest use cases in the world of relational databases: we have an entity, and we need to store certain properties (attributes) of this entity. However, not all instances may have the same set of properties, and furthermore, in […]
There is a quite interesting document on CIS Controls that discusses Information Security using the Pareto principle (80/20).

After reviewing this document, many security professionals discover that when selecting protective measures, they do not start with the most effective ones. The document highlights 5 key measures […]
Colleagues from the PR department have been collecting case studies for several years involving our corporate-class equipment. A significant portion of these are projects in the hospitality sector.

Another day began as expected for a winter day in a short week. Classic tasks were pouring into the task manager — "I sent a letter to Vasily Ivanovich at Sportloto yesterday, instead of Ivan Vasilyevich at Loto-million, where I wrote all sorts of inappropriate things about Vasily Ivanovich, please make sure he doesn't read the letter" or "last year we optimized […]
When I wrote the article 'How to save your own and others' time in interviews, or a little about HR misconceptions' almost a year ago, I assumed the good faith and interest of both parties in a long-term partnership (mutual gain, win-win, all that). However, the reality of the past year shows that the situation in the market is gradually changing for the worse for employees, and […]
In libjpeg-turbo, a library for encoding and decoding images in the JPEG format, a vulnerability (CVE-2019-2201) has been identified that leads to an integer overflow and subsequent heap corruption when processing specially crafted JPEG files. This vulnerability could potentially allow for the creation of an exploit to execute code in the system (the attack requires processing a very large image with a resolution of […

In the previous article, we explored RabbitMQ clustering for achieving fault tolerance and high availability. Now, let’s dive deep into Apache Kafka. Here, the unit of replication is a partition. Each topic has one or more partitions. Within each partition, there is a leader with followers or without them. When creating a topic, the number of partitions and the replication factor are specified. A common value is 3, this […
