  • We are Closing Down the CppCat Project

    26.04.2015
    One odd year ago, we decided to carry out an experiment and release a tool for small teams and single developers as an alternative to the PVS-Studio static code analyzer. This is how a very inexpensive analyzer CppCat was born. Now we can sum up the results of that experiment and admit that it has failed. During its short lifetime, this project has brought us almost as much money as we had put into its development, promotion, and maintenance. Thus, the project has proved unprofitable. And we could have spent all that time (the most valuable resource) on improving PVS-Studio instead, couldn't we? So we have to close down the CppCat project and focus on PVS-Studio. I hope you will find it interesting to learn from someone else's experience of launching a new business idea, for negative experience is still experience. Read more

    Studying programming languages does take time and effort. But you can't avoid the thorny path if you are eager to thoroughly master the language, its principles, means and intricacies. C++ is no exception, and, moreover, is quite a representative example. There are numbers of nuances and subtleties about it that a programmer must know and keep in mind. But, as I've already said, you need time and practice. Read more
  • Analyzing Vim by PVS-Studio in GNU/Linux

    19.03.2015
    You have probably thought that it's going to be another article about how we checked one more open-source project. But this article is actually not as much about the check itself as it is about the practice of using the PVS-Studio analyzer in the fully GNU/Linux environment. It's not by chance that we chose the Vim project for the check, for it had also contributed to the fulfillment of this task. Read more
