From the translator: I present to yours transfer system VM. However I did not manage to open a question as deeply as it is provided in this work. Therefore I decided to share transfer with readers.


Vendors of operating systems face this problem one or two of time a decade: they need to transfer the user base from an old operating system on their very different new OS, or they need to pass from one architecture of a CCP to another with saving of a possibility of start of old applications without modifications, and also to help third-party developers to port the applications on new OS.

1 year, 2 months ago
The NSA published data about the vulnerabilities in different software products found by them. From these data it is visible that 91% of such vulnerabilities in software go to the analysis to vendors for release of updates to products, and the intelligence agency leaves other 9% for itself "for the purpose of ensuring national security". Reuters specifies that charges of the NSA that concealment of data on vulnerabilities undermines immunity to cyberattacks for the companies of the USA using given software were the cause for the publication of data.



Data of the runaway agent of the NSA Edward Snowden, and also research of some families of malicious software by the different anti-virus companies show that the intelligence agency used different backdoors for receipt of the necessary information, and 0day exploits for their reserved installation.

1 year, 1 month ago

What minuses of such architecture can be noted? Solving problems within such architecture, we face a heap of questions: what language (and?) to take what I/O framework to select how to synchronize cache and storage? Heap of infrastructure questions. And why to resolve infrastructure issues when it is necessary to solve a problem? Certainly, one may say, that we like certain X and Y technologies and to transfer these minuses to a framework of ideological. But it is impossible to deny the fact that data are had on somebody distance from a code (the picture higher) that adds latency that can reduce RPS.
