One of the main problems with C++ is having a huge number of constructions whose behavior is undefined, or is just unexpected for a programmer. We often come across them when using our static analyzer on various projects. But, as we all know, the best thing is to detect errors at the compilation stage. Let's see which techniques in modern C++ help writing not only simple and clear code, but make it safer and more reliable.
What is Modern C++?

The term Modern C++ became very popular after the release of C++11. What does it mean? First of all, Modern C++ is a set of patterns and idioms that are designed to eliminate the downsides of good old "C with classes", that so many C++ programmers are used to, especially if they started programming in C. C++11 looks way more concise and understandable, which is very important.

The PVS-Studio team have written an interesting article about the ways in which you might shoot yourself in the foot working with serialization, code examples, where the main pitfalls are, and also about the way static code analyzer can help you avoid getting into trouble.

This article will be especially useful to those who are only starting to familiarize themselves with the serialization mechanism. More experienced programmers may also learn something interesting, or just be reassured that even professionals make mistakes.

However, it is assumed that the reader is already somewhat familiar with the serialization mechanism.

We should understand that the statements described in the article are relevant for some serializers, for example — BinaryFormatter and SoapFormatter; for others, which are manually written serializers, the behavior can be different. For example, the absence of the attribute [Serializable] for the class may not prevent serialization and deserialize it with a custom serializer.

Briefly summarizing all the information, we can formulate several tips and rules:

- Annotate the types, implementing the ISerializable interface with the [Serializable] attribute.
- Make sure that all members annotated by the [Serializable] attribute get correctly serialized;
- Implementing the ISerializable interface, don't forget to implement the serialization constructor (Ctor(SerializationInfo, StreamingContext));
- In the sealed types, set the access modifier private for a serialization constructor, in the unsealed — protected;
- In the unsealed types implementing the ISerializable interface, make the GetObjectData method virtual;
- Check that in the GetObjectData all the necessary members get serialized, including members of the base class if there are such.

We hope you will learn something new from this article, and will become a expert in the sphere of serialization. Sticking to the rules and following the tips that we have given above, you will save time debugging the program, and make life easier for yourself, and other developers working with your classes. PVS-Studio analyzer will also be of great help, allowing you to detect such errors right after they appear in your code.

Roslyn is a platform which provides the developer with powerful tools to parse and analyze code. It's not enough just to have these tools, you should also understand what they are needed for.

The article can be divided into 2 logical parts:

General information about Roslyn. An overview of tools provided by Roslyn for parsing and analyzing the code. We provide a description of entities and interfaces, as well as the point of view of a static analyzer developer.

Peculiarities that should be taken into account during the development of static analyzers. Description of how to use Roslyn to develop products of this class; what should be considered when developing diagnostic rules; how to write them; an example of a diagnostic.

This article is intended to answer these questions. Besides this, you will find details about the static analyzer development which uses Roslyn API.

You are so lucky to be a programmer. I would like to be the programmer.
- Why do not you learn?
- I already tried. I checked out codeacademy and other websites, but it is not mine.
- Yep, the programming is not really for everyone.
- You are well paid, and you can create different things. Almost every day you get some crazy offers at least for 100 thousand dollars.
- Yep, honestly it's very flattering and a little mind-blowing.
- You get your share in the company and you know that the software engineers are always respected. You can implement any idea in the app and get rich. Moreover, you do not need to hire anyone for this.
- Actually, the programming makes me miserable.
- Wow. What do you mean by that?
- In order to be a good programmer, I need to develop a special mindset and that makes me sad. I noticed this in other programmers, of course, not all, but in many.
- What is this mindset?
- This is concentration on the strengths, and not on the weaknesses.
- Why do you need this to become a good coder?
- I work like this:

Presently, the distance learning system has been developing all the time. There is no longer a problem to get a good education remotely. Online learning has several advantages, such as learning at own pace, freedom and flexibility, accessibility, and social equality. The Web offers a variety of services to help gaining new knowledge.

A couple years ago, I worked together with Ken Thompson on the interactive graphics language that was developed by Gerard Holzman in Bell Labs. I was typing quicker, therefore, I sat at the keypad, and Ken stood behind me. We worked quickly and when the compiler gave out an error, I started reflexively digging in a problem, studying the call stack, program output and launching a debugger, and so on. But Ken simply was standing nearby and thinking, ignoring me and a code, which we just wrote. Soon I noticed regularity that Ken often understood the problem faster than me and was saying, “I know, what is going on”. Usually, he was right. I understood that Ken built the mental model of a code, and when something was broken, it was the error in this model. He was thinking of how this problem could arise, so he explained what was wrong with model, or where our code could mirror this model incorrectly.

Today, I am going to talk about how you can hide the “spare" assembler commands in the regular code. This method is useful for complexity of disassembling the code, especially if the generation of "hidden" commands to automate. Tools: debugger - OllyDbg.

Over a year ago one user of StackOverflow programming site asked for help concerning this issue. Namely, they have the employee with the last name Null at the firm. The problem is that because of his name falls a corporate search application, if the employee’s name will be used as search query (it has happened very often recently). Error:

<faultstring>coldfusion.xml.rpc.CFCInvocationException: [coldfusion.runtime.MissingArgumentException : The SEARCHSTRING parameter to the getFacultyNames function is required but was not passed in.]</faultstring>

I have little experience (summarily I have been working as a programmer nearly for 16 months), nevertheless, I would like to give some tips to myself in the past, or in other words, to those who are studding now at the university and planning to become a software developer. I do not have a claim on wisdom or experience on no account. While thinking a little, I understand that all these tips are very actual for me more than ever too. I published the first note in my blog last year, and now I am publishing here the list expanded with tips of the readers of this blog.

All tips are independent and their order does not matter.

The recent Visual Studio 11 Beta version has a new and major built-in feature of the future C # 5 - asynchronous programming using async/await. In this article I would like to structure and examine this quite interesting new tool and share the results with you.

Why is it needed?

C# is actively developing language. Each its version has interesting features that really simplify the writing quality of understandable code. For example, Linq considerably simplified the writing of filters for collections and sql queries in the code. Now the turn came for asynchrony.
