• Makefiles, symlinked folder & relative paths

  - by l.thee.a

  Let say I have the following folders: /A/C /D/B/E /D/B/C (this is a symlink to /A/C created by ln -s) When one of the makefiles tries to use the path /D/B/C/../E it gets a "no file or directory" error.

I.e., the OK button is still labeled "OK". In Windows, for example, it is replaced with the Traditional Chinese equivalent.

• Is SQL DATEDIFF(year, ..., ...) an Expensive Computation?

  - by rlb.usa

  I'm trying to optimize up some horrendously complicated SQL queries because it takes too long to finish. In my queries, I have dynamically created SQL statements with lots of the same functions, so I created a temporary table where each function is only called once instead of many, many times - this cut my execution time by 3/4. So my question is, can I expect to see much of a difference if say, 1,000 datediff computations are narrowed to 100?

• Using cp command in linux shell, how do I copy a whole directory into another directory?

  I have a directory, let's say, "work": ~/work/ This directory has some sub-folders (d1, d2...) in it and files in these sub-folders. I want to make a backup copy in the same folder, so it would be like: ~/backup/work/ However, when I use cp -r ./work ./backup the folder "work" is not copied, only its subfoders (so now it's ~/backup/d1 ~/backup/d2...) Any idea how to make it work? I'm quite new to shell, so I'm missing something :)

  - by Syleron

  I am trying to compare the current url in webView with a defined url say google.com so in theory..

• The simplest concurrency pattern

  - by Ilya Kogan

  Please, would you help me in reminding me of one of the simplest parallel programming techniques. How do I do the following in C#: Initial state: semaphore counter = 0 Thread 1: // Block until semaphore is signalled semaphore.Wait(); // wait until semaphore counter is 1 Thread 2: // Allow thread 1 to run: semaphore.Signal(); // increments from 0 to 1 It's not a mutex because there is no critical section, or rather you can say there is an infinite critical section. So what is it?
