The distributed computing and big data market, according to statistics, is growing by 18-19% per year. Thus, the question of software selection for these purposes remains relevant. In this post, we will start with why distributed computing is needed, take a closer look at software selection, discuss the application of Hadoop using Cloudera, and finally talk about hardware selection and what […]
In the architecture of x86 platforms, two currents have emerged that mutually complement each other. One version suggests moving towards integration of computational and control resources within a single crystal. The second approach advocates the distribution of responsibilities: the processor is equipped with a high-performance bus that forms a peripheral scalable ecosystem. This lays the foundation for the topology of Intel C620 system logic for high-level platforms. The fundamental difference from the previous chipset […]
Today I am once again pleased to present some useful tips from my colleague Evgeny Ivanov, the team lead of Veeam's technical support team. This time, Zhenya shared recommendations for working with backups and replicas. I hope these will help you avoid common mistakes, and your replicas and backups will never become the "weak link" in the recovery process if needed. So, […]
Almost all of us use online shopping services, which means that sooner or later we risk becoming victims of JavaScript sniffers — special code that malicious actors embed on websites to steal credit card information, addresses, usernames, and passwords from users. Nearly 400,000 users of British Airways' website and mobile application, as well as visitors to the British sports website, have already suffered from sniffers […]
Recently, Google released Chrome 74, one of the most controversial updates for the world's most popular web browser. This is particularly true for Windows 10. As known, this version introduced a dark mode that changes in accordance with the OS theme. This means you won't be able to set a dark theme for the OS and a light theme for the browser at the same time […]
Anyone who has assembled, purchased, or at least tuned a radio receiver has probably heard terms like: sensitivity and selectivity. Sensitivity indicates how well your receiver can pick up a signal even in the most remote areas. Selectivity, in turn, shows how well the receiver can tune into a particular frequency without the influence of other frequencies. […]
About a year and a half ago, I started participating in hackathons. During this time, I have taken part in more than 20 events of various scales and themes in Moscow, Helsinki, Berlin, Munich, Amsterdam, Zurich, and Paris. In all these events, I focused on data analysis in one form or another. I enjoy visiting new cities for myself […]
In the previous part of this trilogy, I discussed several reasons to participate in hackathons. The motivation to learn a lot of new things and win valuable prizes attracts many, but often due to the mistakes of the organizers or sponsoring companies, the event ends unsuccessfully and participants leave dissatisfied. To minimize such unpleasant cases, I have written this post. The second part of the trilogy is dedicated to the mistakes of the organizers. This post is organized as follows […]
The chapter in which Doctor Web removes the Samsung Magician service DLL, declaring it a trojan, and to leave a request in the support service, you need not just to register on the portal, but also to provide a serial number. Which, of course, doesn't exist, because Dr.Web sends a key upon registration, and the serial number is generated during the registration process by the key — and is not stored ANYWHERE. […]
In two weeks, intensive courses on Kubernetes will start: Slurm-4 for those getting acquainted with k8s and MegaSlurm for Kubernetes engineers and architects. There are only 10 spots left in the Slurm-4 hall. There are plenty of interested individuals aiming to master k8s at a basic level. For Ops, who are familiar with Kubernetes, launching a cluster and deploying an application is already a decent achievement. For Dev, the requests and […]
Artificial intelligence consistently outplays grandmasters in chess, bests champions in Go, shows prowess in poker tournaments, and easily defeats esports players in strategic games. However, AI still struggles to win in real combat situations, yet this is an aspiration, as stated by the U.S. Department of Defense's DARPA. Operating at high speeds under significant loads […]
The project srsLTE 19.03 has been released, developing an open stack for deploying LTE/4G cellular network components without specialized equipment, using only universal programmable transceivers, with the signal shape and modulation defined programmatically (SDR, Software Defined Radio). The project's code is provided under the AGPLv3 license. SrsLTE includes an implementation of LTE UE (User Equipment, client components for connecting subscribers to the LTE network), basic […]
