I got around this by calling the system 'at' command on Linux. "at run something now". and you have to set atrun -s in a crontab file (to run every minute) to insure that things get kicked off quickly even if there is a heavy load on the machine.If you're the only one ...
Linux fork那些隐藏的开销 fork是一个拥有50年历史的陈年系统调用,它是一个传奇!时至今日,它依旧灿烂。 一个程序员可以永远不用read/write,也可以不懂mmap,但必须懂fork。这是一种格调! fork没有参数,它是如此简单,是UNIX哲学的布道者或者说卫道者们的首选,它被写进了几乎每一本操作系统教科书里,成了创建新...

In this article, we will start from a small explanation of process IDs and then we will quickly jump on to the practical aspects where-in we will discuss some process related C functions like fork(), execv() and wait() . Linux Processes Series: part 1, p

If you're unlucky then the application crashes or freezes in mysterious ways. In theory it can even accidentally wipe your hard drive. Takeaway: the problem has always been there, even before High Sierra and even on Linux. It's just that High Sierra has chosen to fail fast instead of sil...
