Modern programmers live in a very special period of time, when the software is penetrating into literally all spheres of human life and is installed on a numerous amount of devices that are a part of our every day life. Nobody is surprised by software in the fridges, watches and coffee-machines. However, the dependence of people on the smart technology is also growing. The inevitable consequence: the reliability of the software becomes priority number 1. It’s hard to scare someone with a freaked out coffee-maker, although it can bring a lot of harm (liters of boiling coffee flowing on your white marble countertop…). But the thought of growing requirements for the quality of software is really important, that’s why let’s talk about errors in the code that led to significant waste of time and money.

How to capture a variable in C# and not to shoot yourself in the foot
Back in 2005, with the release of C# 2.0 standard we got a possibility to pass a variable to the body of an anonymous delegate by capturing it from the current context. In 2008 the C# 3.0 brought us lambdas, user anonymous classes, LINQ requests and much more. Now it January, 2017 and the majority of C# developers are looking forward to the release of the C# 7.0 standard that should provide us a bunch of new useful features. However, there are still old features that need to be fixed. That’s why there are plenty of ways to shoot yourself in the foot. Today we are going to speak about one of them, and it is related with quite an unobvious mechanism of variable capture in the body of anonymous functions in C#.
Critical stuff that every junior C# developer must know
Says Mosh Hamedani, author of courses on C# at udemy
Mosh, I just got my first junior level C# job. What advice do you have for me? What are some critical stuff I need to learn?
So, whether you’re looking for your first junior C# job, or you just got one, this post will give you an overview of the kind of skills that you need to be familiar with as a junior C# developer. I’ve tried to put it in a “learning path” that would give you direction, whether you want to build web or desktop applications.
Stories about Christmas and New Year Bugs
Do you believe in magic? Of course not – it’s just against logic! Programmers are serious-minded and well-educated people of a realistic outlook. Well, you didn’t favor fairy tales as a child either, did you? OK, I’m not going to answer for you. Just please make yourself a cup of tea, peel a tangerine, look at the snowflakes falling outside the window, and only then go on to read this Story.
The First Bug on Mars
In 1971, the USSR delivered the first planetary rovers on skis to Mars, whose task was to puncture the surface with a rod (housing a dynamic penetrometer and a radiation densitometer) to see if Mars was solid or liquid dusty. The first probe crashed on November 27; the second soft-landed on December 2 but didn’t manage to get out of the “shell” of the lander, so that attempt didn’t count.
C++ versus C
Originally C++ was envisioned as a superset of C: the majority of existing C programs should also be valid C++ programs. The standards have since diverged substantially, but even in the old days there were obscure exceptions:
We continue checking Microsoft projects: analysis of PowerShell
It has become a “good tradition” for Microsoft to make their products open-source: CoreFX, .Net Compiler Platform (Roslyn), Code Contracts, MSBuild, and other projects. For us, the developers of PVS-Studio analyzer, it’s an opportunity to check well-known projects, tell people (including the project authors themselves) about the bugs we find, and additionally test our analyzer. Today we are going to talk about the errors found in another project by Microsoft, PowerShell.
