May Day is approaching, dear Habr users. Not long ago, I clarified for myself how important it is to keep asking simple questions, even if it seems like we already know the answer. So, what are we celebrating? To understand it correctly, we need to take at least a distant look at the history of the issue. Even for a superficial but correct understanding, we need to find the original source. I wouldn't want […]
A new version of the Tutanota email client has been released. The changes include a revamped search feature and integration with Let’s Encrypt for custom domains, as well as a 100% Russian translation. Tutanota uses end-to-end encryption, so the search can only be performed locally. To do this, the client builds a full-text index. The index is stored locally in an encrypted form. The new revamped search should significantly […]
What is Istio? It is a so-called Service mesh, a technology that adds a layer of abstraction over the network. We intercept all or part of the traffic in the cluster and perform a specific set of operations on it. Which ones exactly? For example, we implement smart routing, apply a circuit breaker approach, organize 'canary deployment' by partially switching traffic to a new version of the service, and can limit […]
In the 20th century, people's lives and work followed a plan. At work (simplifying — you can imagine a factory), people had a clear plan for the week, the month, and the year ahead. Simplistically: you need to manufacture 20 parts. No one will come and say that now you need to manufacture 37 parts, and besides, write an article reflecting on […]
I have probably tried to systematically manage tasks about 20-25 times. Each attempt failed, as I now understand, for two reasons. Firstly, to allocate time for task management, one must understand why it is done. You start managing tasks, spend time on it, complete fewer tasks, and all this starts to pile up — for what purpose? Any work is difficult […]
Sometimes writing JavaScript code is challenging, and at times it can be quite daunting, a feeling familiar to many developers. During the process, mistakes inevitably occur, and some of them happen quite frequently. In an article aimed at beginner developers, these mistakes and ways to solve them are discussed. For clarity, the names of functions, properties, and objects are taken from a popular song. All of this helps […]

The Association of Internet Trade Companies (AKIT) proposed a new initiative that involves changes to the existing customs duties on expensive parcels from abroad. It is suggested to replace the disparate tax contributions with a single fee of 15%. According to 'Kommersant', this is a softer option, as initially the discussion was about 20%. The proposal is currently under consideration at the Analytical Center under the government, the Gaidar Institute, and 'Post […]
Microsoft has changed the storage device requirements for installing the operating system. Now, in Windows 10, starting with version 1903 (this update is expected in May 2019), the minimal free disk space required for the operating system to function is at least 32 GB for both 32-bit and 64-bit versions. Thus, the 'Reserved storage' of 7 GB from […]
In the previous article, we examined the basic components of the Istio Service Mesh, got acquainted with the system, and answered the main questions that usually arise at the beginning of working with Istio. In this part, we will look at how to organize the collection of tracing information across the network. The first thing that comes to mind for many developers and system administrators when they hear the words Service […]

A new future, the picture of which we described in the previous article about connecting humans to the Internet, is expected to await humanity in the next 20 years, according to several researchers. What is the overall direction of human development? Significant financial flows are being invested in improving the quality of life. The main sources of decline in overall quality of life are various diseases and mortality. Work on […]
