As an experiment, we have decided to offer everyone interested a PVS-Studio registration key for 5 days to study its 64-bit diagnostics more thoroughly. The PVS-Studio demo version is absolutely full-function. It is sufficient to study the tool and get familiar with its capabilities. The user has up to 200 clicks to navigate through code fragments the analyzer considers to be probably incorrect. We believe it's quite enough for the user to decide if he/she likes the tool or not. However, that might be insufficient in case you are searching for 64-bit errors. Many of the 64-bit warnings are false positives or are irrelevant to this program, as fragments they point to cannot cause errors. That's why the restriction of 200 messages you can click to navigate through the code may prevent you from forming a definite opinion of the tool. We have been watching an increasing interest towards development of 64-bit software lately. Perhaps this has to do with the release of Embarcadero RAD Studio XE3 Update 1 that has learned now to compile 64-bit applications. Or maybe it's just that the time has come.

I recently wrote about dlmalloc and how it is a poor choice for a memory allocator for console games. As I explained in my previous article, dlmalloc has two major limitations. It manages a pool of address space composed of discrete regions called segments. It can easily add segments to grow its pool of address space, but it can't easily remove segments to return address space to the OS. Additionally, it doesn't distinguish between physical and virtual memory, which means that it can't take advantage of virtual memory's ability to combat fragmentation.

We continue last week's discussion by getting down to details. We continue last week's discussion by getting down to details. If you haven't read it, please do so now; I'll wait. Thanks! We'll start by defining three important implementation-dependent types: ...

It is an open-source testing framework for java programmers. The java programmer can create test cases and test his/her own code. It is one of the unit testing framework. Current version is junit4. To perform unit testing, we need to create test cases.

We have a practice of occasionally re-analyzing projects we have already checked with PVS-Studio. There are several reasons why we do so. For example, we want to know if we have managed to eliminate false positives for certain diagnostics. But the most interesting thing is to see how new diagnostic rules work and what errors they can find. It is very interesting to watch the tool catch more and more new defects in a project that seems to be cleaned out already. The next project we have re-checked is Clang.

This article covers the extension of Visual Studio IDE through integration of a custom user toolwindow into the environment. Discussed are the issues of window registration and initialization in VSPackage and Add-In plug-in modules, hosting of user components and handling of window's events and states.

We have checked the Windows 8 Driver Samples pack with our analyzer PVS-Studio and found various bugs in its samples. There is nothing horrible about it - bugs can be found everywhere, so the title of this article may sound a bit high-flown. But these particular errors may be really dangerous, as it is a usual practice for developers to use demo samples as a basis for their own projects or borrow code fragments from them.

AJAX allows you to send only important information to the server not the entire page. So only valuable data from the client side is routed to the server side. It makes your application interactive and faster.

The best way to advertise a static code analyzer is to find errors in open source projects and share them with the world. We have been using this method for a long time while promoting our tool PVS-Studio. If you have ever heard of PVS-Studio, it was most likely from our articles reporting on the checks of such projects as Chromium, WinMerge, TortoiseSVN, Apache HTTP Server, Qt, Clang and many others.
