According to research by HeadHunter and Mail.ru, the demand for specialists in the field of Data Science exceeds supply, yet even so, young professionals do not always manage to find a job. We explain what graduates of courses lack and where to learn for those planning a significant career in Data Science. "They come in thinking they will earn 500k a second just because they know […]
Performance analysis and tuning is a powerful performance compliance checking tool for clients. Performance analysis can be applied to identify bottlenecks in a program, employing a scientific approach in the experimentation process for tuning. This article outlines a general approach to performance analysis and tuning using a web server on Go as an example. Go is particularly well-suited here, as […]
TODAY, August 3rd at 8:00 PM, there will be a live stream with Sergey Shirkhin on how to build a successful career in AI. The stream can be watched on any of our social media platforms — watch wherever is convenient for you. Sergey Shirkhin is a pioneer of the faculties of Artificial Intelligence, Big Data Analytics, and Data Engineering at Geek University, where he serves as dean and instructor. […]
Currently, blockchains are largely isolated from external information sources — both centralized resources and other blockchains. To ensure different blockchains are compatible and can easily exchange data with one another (and with external resources), oracles can be used. What are oracles? An oracle is a system that retrieves and verifies events from outside the blockchain and transmits this data […]
The profession of a system administrator is always accompanied by stereotypical perceptions. A sysadmin is often seen as a jack-of-all-trades IT specialist in any company who fixes computers, establishes the Internet, handles office equipment, configures software, etc. It has even reached the point where a System Administrator Day has been established — the last Friday in July, which is today. Moreover, the holiday celebrates its anniversary today — the first System Administrator Day was celebrated […]
The translation of this article has been prepared in anticipation of the launch of the course "DevOps Practices and Tools." If you are reading this, you have probably heard something about Kubernetes (and if not, how did you end up here?). But what exactly is Kubernetes? Is it an "Industrial-Grade Container Orchestration"? Or a "Cloud-Native Operating System"? What does this even mean? Honestly, I don't […]
Bitdefender has announced the open-sourcing of its Hypervisor Introspection (HVI) technology. It was developed in collaboration with the Xen project. The project's history began in 2015 when the libbdvmi library was introduced for Hypervisor 4.6. This library allowed virtual machines and software that searches for malicious code to be 'friends'. Previously, specialized malware could remain undetected for a long time […]
Recently, colleagues in the field have independently started asking me: how to receive all Bluetooth channels simultaneously from one SDR receiver? The bandwidth allows it, and there are SDRs with an output bandwidth of 80 MHz or more. It is certainly possible to do this on an FPGA, but the development time for such a solution will be quite significant. I have long known that it can be done on […]
System Administrator Day (or rather, the day to recognize their contributions) is a wonderful opportunity to reflect on oneself from an outside perspective. To see oneself and one's work through the eyes of loved ones. The title 'system administrator' sounds quite vague. Sysadmins are responsible for a wide range of different devices, from desktops to servers, printers, and air conditioners. Therefore, when introducing oneself to another IT professional, it's essential to add at least one qualification. For example, […]
Preliminary notification: this post is strictly a Friday one and more entertaining than technical. You can expect fun stories about engineering mishaps, tales from the dark side of working with a mobile operator, and other lighthearted anecdotes. If I embellish any details, it’s only for the sake of storytelling, and if I lie, those incidents are from long ago, so it won't matter to anyone. […]
TL;DR: an overview guide comparing environments for running applications in containers. The capabilities of Docker and other similar systems will be discussed. A bit of history on where it all began. The first well-known method of isolating an application is chroot. The system call of the same name changes the root directory, thus ensuring that the program that called it has access only to the files within that directory. But […]
Hello everyone! Today we will try to automate the process of creating assignments using the data platform Microsoft Common Data Service along with Power Apps and Power Automate services. Based on Common Data Service, we will build entities and attributes, create a simple mobile application using Power Apps, and Power Automate will help connect all components with a unified logic. Let's not waste any time! But […]
