On September 4th, the Slyrm DevOps event kicked off in St. Petersburg. All the necessary factors for an engaging three-day intensive gathered in one place and time: a comfortable conference hall at Selectel, seventy curious developers in the room, and 32 participants online, along with Selectel servers for practice. And a green dinosaur, lurking in the corner. On the first day of Slyrm, the participants […]
Fear sees, but hands itch! In previous articles, we explored the technologies behind blockchains (What does it take to build a blockchain?) and the cases that can be implemented with them (What does it take to build a case?). It's time to get hands-on! For implementing pilots and PoC (Proof of Concept), I prefer using cloud environments, as they are accessible […]
This article was born in response to the article 'The Ideal Local Network.' I disagree with most of the author's points and want to not only refute them in this article but also put forward my own points, which I will defend in the comments. Next, I will talk about several principles I adhere to when designing the local network of any business. The first principle is […]
Discussing the acquisition of a virtualization software developer and Avi Networks. / photo by Samuel Zeller Unsplash What You Need to Know In June, VMware announced the acquisition of startup Avi Networks. They develop tools for deploying applications in multi-cloud environments. It was founded in 2012 by former Cisco vice presidents and directors responsible for various business development sectors of the company. […]
Hello everyone. In this article, I will explain why we at Avito chose Kafka nine months ago and what it is all about. I will share one of the use cases — message broker. Finally, we will discuss the benefits we gained from implementing Kafka as a Service. The Problem To start, a bit of context. Some time ago we […]
"I am now a cyborg!" proudly declares Australian Liam Zabidi, a young programmer, blockchain/Fullstack engineer, and writer, as he presents himself on his blog pages. In early August, he completed his DIY project of creating a wearable device that he unashamedly calls an 'artificial pancreas.' It is really more of a self-regulating insulin pump, and our cyborg in some […]
TL;DR: Can Haiku receive proper application package support, for instance, application catalogs (like .app on Mac) and/or application images (Linux AppImage)? I believe this would be a worthy addition that is easier to implement here than in other systems, as much of the infrastructure is already in place. A week ago, I discovered Haiku, unexpectedly a great system. And since […]
In May of this year, I participated as a player in the MMO event KatherineOfSky. I noticed that when the number of players reached a certain threshold, some of them would 'drop out' every few minutes. Fortunately for you (but not for me), I was one of those players who disconnected each time, even with a good connection. I perceived this […]
There are people who love to use high-quality components from the enterprise segment in everyday life. They want to be sure that their SSD won't suddenly fail due to a power outage or write amplification when downloading massive 4K torrents onto a fragmented NTFS partition with a 4K cluster size or during another Gentoo source compilation. Of course, such concerns rarely come to fruition […]
In 2017, we won a competition to develop the transactional core for Alfa-Bank's investment business and started working on it (Vladimir Dryinkin, the head of the investment business transaction core project at Alfa-Bank, spoke at HighLoad++ 2018 about the investment business core). This system was meant to aggregate transaction data from various sources in different formats, unify the data to a common view, […]
Conceiving the development of a cloud helpdesk system in 2018 seemed to be an unwise idea at first glance — on the surface, the market exists, there are domestic and foreign solutions, and plenty of custom systems as well. To think of developing a new system when you already have a large CRM development and over 6,000 'live' and active clients who constantly need something — that’s a significant resource […]
Today we will discuss router and switch password recovery, updating, reinstalling, and restoring IOS, as well as the Cisco licensing system for the IOSv15 operating system. These are very important topics related to network device management. How can you recover a password? You might ask why this might be necessary. Suppose you have configured a device and set all the necessary passwords: for VTY, for the console, […]
