Some programs are vulnerable to symlink races. To avoid this problem with wipe, only wipe files in directories that are not writable by untrusted users. Wipe uses/dev/urandom, or if unavailable,/dev/random, as a source

New technologies help you solve problems with high WiFi costs Are you still worried about your WiFi? Don't worry. Recently, a team of computer scientists and electrical engineers from the University of Washington has developed a very efficient Wi-Fi wireless network technology.What are the main features of new configurations? Researchers at the University of Washington who participated in the development of this technology have demonstrated that weak radio signals can indeed meet the power nee

layer can obviously be shared across multiple applications, saving cost. If we re-adjust the load-balancing hierarchy in front of us in this way, it will evolve into the following.In fact, at this point I think the application of the front layer of Nginx may seem superfluous, not necessary. But if the reality of this evolution is likely to have such a layer of redundant things for a long time, this is the gap between ideal and reality.SummarizeOkay, here's the end of this article.
