Convert time to Unix time
Unix time is defined as the number of seconds that have elapsed since midnight Coordinated Universal Time (UTC), 1 January 1970,not counting leap seconds. It is used widely in Unix-like and many other operating systems and file formats. It is neither a linear representation of time nor a true representation of UTC. Unix time may be checked on some Unix systems by typing date +%s on the command line. Sometimes it's a bit difficult to compare times stored in different applications or systems with ...

Why email is crucial to Google, Microsoft and Yahoo
Google, Microsoft and Yahoo. These three companies rule webmail withGmail, Hotmail and Yahoo Mail, the three largest email services on the Internet.What might escape a lot of people, though, is just how important email services are for the online presence of those companies (yes, even for Google).

How to find which process a file is being written by in Linux?
Some people ask a file is being written by one process and they want to check this process, but they cannot find the process even with sof. This question is very common and there are many solutions, here we introduce a straightforward method. In Linux, each file will be stored on one device and of course there will be a relative inode, then we can use vfs.write to know who is writing the inode on one specified device continuously. Luckily there is inodewatch.stp in the installation package of s...

Why Software Projects are Terrible and How Not To Fix Them
If you are a good developer and you’ve worked in bad organizations, you often have ideas to improve the process. The famous Joel Test is a collection of 12 such ideas. Some of these ideas have universal acceptance within the software industry (say, using source control), while others might be slightly more controversial (TDD). But for any particular methodology, whether it is universally accepted or only “mostly†accepted, there are a multitude of o...
