Here is a bit refreshed translation of my 2015 blog post. The post shows how to organize a personal academic library of unlimited size for free. This is a funny case of a self written manual which I came back to multiple times myself and many many more times referred my friends to it, even non-Russian speakers who had to use Google Translator and infer the rest from screenshots. Finally, I decided to translate it adding some basic information on how to use Zotero with rmarkdown.

A brief (and hopefully unnecessary for you) intro of bibliographic managers

Bibliographic manager is a life saver in everyday academic life. I suffer almost physical pain just thinking about colleagues who for some reason never started using one — all those excel spreadsheets with favorite citations, messy folders with PDFs, constant hours lost for the joy-killing task of manual reference list formatting. Once you start using a reference manager this all becomes a happily forgotten nightmare.

Previously we did code reviews of large mathematical packages, for example, Scilab and Octave, whereby calculators remained aloof as small utilities, in which it is difficult to make errors due to their small codebase. We were wrong that we haven't paid attention to them. The case with posting the source code of the Windows calculator showed that actually everyone was interested in discussing types of errors hiding in it. Moreover, the number of errors there was more than enough to write an article about that. My colleagues and I, we decided to explore the code of a number of popular calculators, and it turned out that the code of the Windows calculator was not that bad (spoiler).

Cross-platform application development is extremely useful among software development organizations because a large end-user audience can be targeted. Earlier there were several approaches, such as writing multiple codebases per each platform, writing a single codebase using conditionals for platform selection, or using a programming language which has a cross-platform virtual machine at run-time. There were drawbacks of each like complexity of design, limited low-level accessibility and slow learning rate. Cross-platform application development with web technologies came [1] after. Electron and NW.js are most popular frameworks which allow developers to make cross-platform applications using Javascript. Basically, these popular frameworks combine embedded chromium browser and node run-time [2], [3].

These frameworks are being used to create numerous cross-platform applications. Whereas the community pointed out several unseen drawbacks of these frameworks. Large bundled application size, high memory consumption and long development workflow are the key things which were criticized through internet forums and websites [4], [5], [6], [7], [8]. Table 1.1 shows the advantages and disadvantages of Electron/NW.js.

Table 1.1: Advantages and Disadvantages of Electron/NW,js

Advantages of Electron and NW.js	Disadvantages of Electron and NW.js
Development is very easy since Javascript is used	Application bundle is considered as bloatware (High disk space usage)
Access native functions via node runtimeSingle codebase for all supported platforms Linux, Windows and macOS	High memory consumption and slowness
	Many Node modules need to be installed

Today, we’re excited to announce that we are open sourcing Windows Calculator on GitHub under the MIT License. This includes the source code, build system, unit tests, and product roadmap. Our goal is to build an even better user experience in partnership with the community. We are encouraging your fresh perspectives and increased participation to help define the future of Calculator.

A few days ago, Microsoft made the source code of their Windows Calculator publicly available. Calculator is an application that has traditionally shipped with every Windows version. A number of Microsoft projects went open-source over the recent years, but this time the news was covered even by non-IT media on the very first day. Well, it's a popular yet tiny program in C++. Despite its size, we still managed to find a number of suspicious fragments in its code using the PVS-Studio static analyzer.

Good day to you!

My name is Stanislav and I like to write code. This is my first english article on Habr which I made due to several reasons:

• Habr is now in English
• Lack of technical articles in the ReactOS hub
• Recent return of Geektimes to Habr
• Possibility of building ReactOS in ReactOS
• Quite interesting case of fixing the problem in ReactOS in which I was directly involved

This article is an english version of my very first article on russian.

Let me introduce the main figures in this story who actually fixed the bug preventing Git from running in ReactOS — the French developer Hermès Bélusca-Maïto (or just Hermes with hbelusca nickname) and of course me (with x86corez nickname).

The story begins with the following messages from the ReactOS Development IRC channel:

Jun 03 18:52:56 <hbelusca> Anybody want to work on some small problem? If so, can someone figure out why this problem https://jira.reactos.org/browse/CORE-12931 happens on ReactOS? :D
Jun 03 18:53:13 <hbelusca> That would help having a good ROS self-hosting system with git support.
Jun 03 18:53:34 <hbelusca> (the git assertion part only).

In this article, we invite you to try to find a bug in a very simple function from the GNU Midnight Commander project. Why? For no particular reason. Just for fun. Well, okay, it's a lie. We actually wanted to show you yet another bug that a human reviewer has a hard time finding and the static code analyzer PVS-Studio can catch without effort.

Sberbank is the largest bank in Russia and Eastern Europe. Our team in Sbertech teaches Sberbank efficient work with Free & Open Source Software. You can read more about this on Habr (what we exactly do, yet in Russian).

One of the main challenges is to open the mind of managers and engineers for using FOSS (Free & Open Source Software) properly. Because we have a lot of them, we have tried to use GIFs for answer the most common questions.

The original post has been updated based on community input in order to remove confusion.

Final version of the whitepaper is available here:

Welcome to all fans of trashing someone else's code. :) Today in our laboratory, we have a new material for a research — the source code of the AWS SDK for .NET project. At the time, we wrote an article about checking AWS SDK for C++. Then there was not anything particularly interesting. Let's see what .NET of the AWS SDK version is worth. Once again, it is a great opportunity to demonstrate the abilities of the PVS-Studio analyzer and make the world a bit better.

In the seventh version of the PVS-Studio static analyzer, we added support of the Java language. It's time for a brief story of how we've started making support of the Java language, how far we've come, and what is in our further plans. Of course, this article will list first analyzer trials on open source projects.
