Hello, Habr! On April 22 of this year, I wrote an article on Habr about discounts on CRM systems. At that time, I thought that price was the most important selection criterion, and everything else I could easily handle with my brains and experience as a sysadmin. The boss was expecting quick wonders from me, employees settled in to lounge around and work from home, COVID was spreading across the planet, and I was choosing a system […]
Image: Designmodo Just a few years ago, launching any online business was fraught with difficulties. You had to find developers to create the website – especially if any deviations from the functionality of regular builders were required. If a mobile app or chatbot was also needed, it became even more complicated, and the budget just for the launch […]
Recently, Cloud4Y held a webinar dedicated to the issues of TCO, or total cost of ownership. We received a multitude of questions on this topic, reflecting the audience's desire to understand it better. If you are hearing about TCO for the first time or want to understand how to properly assess the benefits of using your own or cloud infrastructure, it's worth checking it out. When […]
This year, we started a major project to create a cyber range – a platform for cyber exercises for companies from various industries. This involves creating virtual infrastructures that are 'identical to real ones' — so that they replicate the typical internal structure of a bank, an energy company, etc., not only in terms of the corporate segment of the network. We will share more details about the banking and other infrastructures of the cyber range later, and […]
– Oh, no shelter will withstand a meteor strike. But you have backups, like everyone else, so you need not worry. Stanislaw Lem, "The Star Diaries of Ijon Tichy". Backup refers to storing copies of data somewhere outside the primary storage location. The main purpose of backup is to recover data after loss. In connection with this […]
In the previous publication, we looked at how to create a bot, initialized an instance of the Bot class, and explored methods for sending messages using it. In this article, I continue this topic, so I recommend reading this article only after going through the first part. This time we will figure out how to bring our bot to life and add command support to it […]
In this article, we will use bash, ssh, docker, and nginx to organize a seamless deployment of a web application. Blue-green deployment is a technique that allows instant updates to the application without rejecting any request. It is one of the zero downtime deployment strategies and is best suited for applications with a single instance, but with the capacity to load a second, fully prepared instance alongside it […]
For the last 40 years, Nintendo has been actively experimenting in the mobile gaming sector, testing various concepts and creating new trends that other console manufacturers quickly adopt. During this time, the company has produced numerous portable gaming systems, with hardly any being outright failures. The culmination of Nintendo's long-standing explorations was supposed to be the Nintendo Switch, but something […]
Hello, Habr readers. As we mentioned, this month OTUS is launching two courses on machine learning: a basic and an advanced one. In connection with this, we continue to share useful material. The goal of this article is to discuss our first experience using MLflow. We will begin the review of MLflow with its tracking server and document all iterations of the study. Then we will share […]
Author: Sergey Lukyanchikov, consultant engineer at InterSystems The Challenges of Real-Time AI/ML Computations Let’s start with examples from the Data Science practice of InterSystems: a 'burdened' customer portal is connected to an online recommendation system. There will be a restructuring of promotional campaigns across the retail network (for instance, instead of a 'flat' range of promotions, a 'segment-tactic' matrix will be used). What happens to the recommendation mechanisms? What happens to the submission and updating of data […]
Next, you will find instructions for setting up AWS MFA, followed by the installation and configuration of AWS CLI. Unfortunately, this mandatory procedure took me half a workday. To help other uncertain AWS users 😉 like I was, not to waste precious time on the mundane, I decided to put together this guide. Even for a sandbox account, setting up MFA is usually […]
Introduction This article is intended for those who are familiar with the concept of ontology at least at a basic level. If you are not familiar with ontologies, you may not understand the purpose of ontologies and this article in particular. I recommend familiarizing yourself with this phenomenon before starting to read this article (an article from Wikipedia might suffice). […]
