A:
Somehow the postfix program was modified and instead of writing to /var/log/mail.info file it wrote to
/var/log/mail.err
that caused the mail to be lost.
I've managed to fix it by deleting the file and the issue has not reoccurred.
The present invention relates to power MOSFET switches, and more specifically, to a power MOSFET switch using a pinned layer structure.
As the size of an integrated circuit device decreases, the need to integrate more power electronics on a single chip becomes critical. At the same time, device reliability becomes more critical, as thermal management becomes more difficult and more expensive.
As the complexity of devices increases, the risk of defects and error rates also increases. As the complexity of the devices increases, the risk of thermal and electrical disturbance of devices on the chip increases.Q:
Understanding Thread.yield() and/or Thread.sleep(0)
I am using a multithreaded server using a ThreadPoolExecutor with 1 thread running on a single processor, from what I have learned it has to be using a FIFO queue. I am using a ThreadPoolExecutor, however, I am also creating a new ExecutorService, which has different requirements and this is where I am confused.
I was wondering what the differences are of using the Thread.yield() and Thread.sleep(0) methods?
ExecutorService e = Executors.newCachedThreadPool();
ThreadPoolExecutor t = new ThreadPoolExecutor(1, 1, 10, TimeUnit.SECONDS,
new LinkedBlockingQueue(1));
This is how I am currently using the executor service, however I am wondering if I should use the Thread.yield() method?
A:
Both statements are functions that do exactly the same thing. The difference is that Thread.yield() causes the calling thread to pause for a limited time (depends on the current thread state) while Thread.sleep(0) causes the thread to just keep going.
As for why you should or shouldn't use either method, it depends on your situation. Sometimes it is better to pause the thread (for example when processing a large amount of data) and sometimes ac619d1d87
