Preparation My wife and I started actively preparing about 3 years […]
MediaTek has announced the Helio G80 processor, designed for use in relatively affordable smartphones with gaming capabilities. The chip features an octa-core configuration, including two ARM Cortex-A75 cores clocked up to 2.0 GHz and six ARM Cortex-A55 cores clocked up to 1.8 GHz. The graphics subsystem includes an ARM Mali-G52 MC2 accelerator. It supports operation with […]
A collection of graphs and results from various studies with short annotations from the author of the Telegram channel Groks. Engaging infographics about the trillion-dollar smartphone economy. Sales of the phones themselves account for nearly half of all revenue. Purchases of applications make up a quarter of that amount, with advertising accounting for even more. Accessories add 16% to their cost. The share of music exceeds that of video. A couple of […]
A correct and accurate translation is a complex and responsible task. The more critical the translation, the more catastrophic the consequences a translator's mistake can lead to. Sometimes such an error costs a human life, and among them, there are those that have cost tens of thousands of lives. Today, we will discuss translation errors that have proven to be too costly for history. In light of […]
Google has released the Chrome 80 web browser. A stable version of the open-source Chromium project, which underpins Chrome, is also available. The Chrome browser is distinguished by the use of Google logos, a notification system in case of crashes, the ability to load Flash modules on demand, modules for playing protected video content (DRM), an automatic update installation system, and the transfer of RLZ parameters during searches. The next release, Chrome 81 […]
Google has released the final version of Chrome 80, which includes a number of new features. This build has introduced a tab grouping function, allowing users to collect tabs with a common name and color into groups. By default, it is enabled for some users, while others can activate it via the option chrome://flags/#tab-groups. Another new feature is a stricter cookie policy if […]
Wireguard is a simple and secure VPN protocol, primarily developed by Jason A. Donenfeld. For a long time, the kernel module implementing this protocol was not accepted into the main branch of the Linux kernel because it used its own implementation of cryptographic primitives (Zinc) instead of the standard crypto API. Recently, this obstacle has been overcome, thanks in part to updates accepted into the crypto API. […]
The background, so to speak: Fujitsu rx300 s6 server, RAID6 made of 6 1TB disks, running XenServer 6.2, hosting several servers, including Ubuntu with multiple shares, 3.5 million files, 1.5TB of data, all gradually growing and bloating. The task: to set up data backup from the file server, partly on a daily basis, partly weekly. We have a Windows machine for backup with RAID5 […]

You don’t have to be a chip developer to program for FPGA, just as you don’t need to be a C++ programmer to write Java code. However, in both cases, it might be beneficial. The goal of commercializing both technologies, Java and FPGA, is to refute the last statement. The good news for FPGA is that with the right levels of abstraction and a set of […]
Let's take a look at the report by Alexey Lesovsky from Data Egret titled 'Fundamentals of PostgreSQL Monitoring'. In this report, Alexey Lesovsky will discuss the key aspects of PostgreSQL statistics, what they mean, and why they should be included in monitoring; which graphs should be part of monitoring, how to add them, and how to interpret them. This report will be valuable for database administrators, system […]
Every few years, the software development industry experiences a paradigm shift. One such phenomenon is the increasing interest in the microservices concept. Although microservices are not a new technology, their popularity has soared recently. Large monolithic services are now being replaced by independent, autonomous microservices. A microservice can be seen as an application that […]
