This article comprises the second part of my speech at the multithreading meetup. You can have a look at the first part here. In the first part, I focused on the basic set of tools used to start a thread or a Task, the ways to track their state, and some additional neat things such as PLinq. In this part, I will fix on the issues you may encounter in a multi-threaded environment and some of the ways to resolve them. Read More

The need to do things in an asynchronous way – that is, dividing big tasks between multiple working units – was present long before the appearance of computers. However, when they did appear, this need became even more obvious. It is now 2019, and I’m writing this article on a laptop powered by an 8-core Intel Core CPU which, in addition to this, is simultaneously working on hundreds of processes, with the number of threads being even larger. Next to me, there lies a slightly outdated smartphone which I bought a couple of years ago – and it also houses an 8-core processor. Specialized web resources contain a wide variety of articles praising this year’s flagship smartphones equipped with 16-core CPUs. For less then $20 per hour, MS Azure can give you access to a 128-core virtual machine with 2 TB RAM. But, unfortunately, you cannot get the most out of this power unless you know how to control interaction between threads. Read More

Recently, I was involved in the development of the functionality that required a fast and frequent transfer of large volumes of data to disc. In addition, this data was supposed to be read from disk from time to time. Therefore, I was destined to find out the place, the way and the means for storing this data. In this article, I will briefly review the task, as well as investigate and compare solutions for completion of this task.

Context of the task: I work in a team that develops tools for relative database development (SQL Server, MySQL, Oracle). The tool range includes both, standalone tools, and add-ins for MS SSMS.

Task: Restoring documents that were opened at the moment of IDE closing at the next start of IDE. Read More

GDI leak (or, simply the usage of too many GDI objects) is one of the most common problems. It eventually causes rendering problems, errors, and/or performance problems. The article describes how we debug this problem.

In 2016, when most programs are executed in sandboxes wherefrom even the most incompetent developer cannot harm the system, I am amazed to face the problem I will speak about in this article. Frankly speaking, I hoped that this problem had gone forever together with Win32Api. Nevertheless, I faced it. Before that, I just heard horror stories about it from old more experienced developers.
