• Cross platform millisecond timer lasting more than 49 days?

  - by Cetra

  Hey guys, I'm going to be developing a small dedicated server in C/C++ that will require uptime of forever. I've been looking into some time functions as millisecond timing is required for calculations. I have 2 problems that I'm facing: Using a 32bit integer to store the number of milliseconds since the operation began will wrap around at about the 49 days mark resetting to zero. There doesn't seem to be any standard system calls for getting elapsed milliseconds that are platform independant What should I do to resolve both these issues?

• Updating an atom with a single value

  - by mikera

  I have a number of atoms in my code where a common requirement is to update them to a new value, regardless of the current value. I therefore find myself writing something like this: (swap! atom-name (fn [_] (identity new-value))) This works but seems pretty ugly and presumably incurs a performance penalty for constructing the anonymous closure. Is there a better way?

• How to calculate "holes" in timetable

  - by genesiss

  I've got a 2-dimensional array like this (it represents a timetable): http://www.shrani.si/f/28/L6/37YvFye/timetable.png Orange cells are lectures and whites are free time. How could I calculate number of free hours between lectures in the same day? (columns are days and rows are hours) For example, in this table the result should be: 2 for first column 0 for second colum -- The function returns 2 (because 2+0=2)

• task strategies for handling HardDeadlineExceededError

  - by Stevko

  I've got a number of tasks/servlets that are hitting the HardDeadlineExceededError which is leaving everything hanging in an 'still executing' state. The work being done can easily exceed the 29 second threshold. I try to catch the DeadlineExceededException and base Exception in order to save the exit state but neither of these exception handlers are being caught... Is there a way to determine which tasks are in the queue or currently executing? Are there any other strategies for dealing with this situation?
