At Microsoft, we are focused on the idea of enabling developers to create quality applications more quickly. One way to achieve this goal is by providing a range of products and services that cover all stages of the software development life cycle. This includes IDEs and DevOps tools, cloud application and data platforms, as well as operating systems […]
Historically, the IT industry has divided itself into two camps on any given issue: those 'for' and those 'against'. The topics of debate can be completely arbitrary. Which OS is better: Win or Linux? Should you use Android or iOS on your smartphone? Keep everything in the cloud or store it on cold RAID storage and lock the drives in a safe? Do PHP developers have the right […]
Ansible has become one of the most popular Configuration Management systems. After being acquired by Red Hat in 2015, the number of project contributors exceeded a thousand, and Ansible has likely become the most widely used deployment and orchestration system. Its vast range of applications is truly impressive. Ansible operates through SSH connections to remote hosts. It opens an SSH session, logs in, copies […]

RIT++ is a professional festival for those who create the Internet. Just like at a music festival, we have many streams, but instead of musical genres, we focus on IT topics. As organizers, we strive to anticipate trends and find new sounds. This year’s theme is 'quality,' along with the QualityConf conference. We do not shy away from beloved themes in new interpretations: splitting monoliths and microservices, […]
Among the handheld devices from Psion, there are five models that do not require emulation since they operate on NEC V30 processors compatible with 8086, hence the name SIBO – sixteen bit organizer. These processors also have a compatibility mode with the 8080, which is understandably not used in these devices. At one time, Psion released proprietary […]
We are talking about the directions in which ITSM is developing in 2019. / Unsplash / Alessio Ferretti Chatbots Automation saves time, money, and human resources. One of the most promising areas of automation is technical support. Companies are implementing chatbots that take on part of the support specialists' workload — providing answers to the most frequently asked questions. Advanced systems can analyze customer behavior, […]
Yesterday, we published a collection of materials on Habr for those who would like to understand ITSM — to study trends and tools. Today, we continue to discuss how to integrate ITSM into a company's business processes and what cloud tools can assist with that. / PxHere / PD What does this mean for you? The traditional approach to managing IT departments is called 'resource management'. If […]
I decided to share my story. Maybe this budget solution to a well-known problem will help someone. When I was young and full of energy and didn’t know where to channel it, I decided to do a little freelancing. I quickly managed to build my rating and found a couple of regular clients who asked me to maintain their servers on an ongoing basis. The first thing I thought of […]
Background It so happened that the server was attacked by ransomware, which, by a 'happy coincidence,' partially left .ibd files (raw data files of InnoDB tables) untouched, while completely encrypting .fpm files (structure files). The .idb files could be divided into: those recoverable through standard means and guides. For such cases, there is a great article; partially encrypted […]
Reflections on where the desire to pass the AWS Solutions Architect Associate certification comes from. Motivation one: “Axes”. One of the most useful principles for any professional is 'Know your tools' (or in one of the variations 'Sharpen the saw'). We’ve been in the cloud for a long time, but until now, they were just monolithic applications with databases deployed on EC2 instances — […]
