• timing control for parallel processes

  - by omrihsan

  how can i control two processes to run alternately in separate terminal windows. for example i run the code for each on separate terminal windows at 11:59 and both of them wait for the time to be 12:00. at this moment process one starts execution and process two waits for say 10 seconds. then they switch, process two executes and process one waits. in this way they take turns until the process is complete.

• bit ordering and endianess

  - by Neeraj

  I am reading a file byte-by-byte. Say for example i have this byte: 0x41 (0100 0001) represented in hex. Now, I want the first three bits of this byte, i.e (010). I can use bitwise logic to extract the first three bits, but my question is will the first three bits be independent of endianess of the machine.(i.e they can't be 001)? Thanks,

  Say I have a path with 150 nodes / verticies. How could I simplify if so that for example a straight line with 3 verticies, would remove the middle one since it does nothing to add to the path. Also how could I avoid destroying sharp corners? And how could I remove tiny variations and have smooth curves remaining. Thanks

• what is the required code method of making a sticker app?

  - by zeropt7

  I am new to photo apps, recently I am interested in making a sticker app like those can be seen in the appstore, I know I would need to use uiimagepickercontroller, uiscrollview and uigesturerecognizer. However I wonder which code method should I use for the app to load multiple stickers? Should it be called programmatically? Is that I would need to use the if-statement, say if one sticker is loaded, the app will auto generate a new sticker on top of it?

• Find all possible starting positions of a regular expression match in perl, including overlapping matches?

  - by jonderry

  Is there a way to find all possible start positions for a regex match in perl? For example, if your regex was "aa" and the text was "aaaa", it would return 0, 1, and 2, instead of, say 0 and 2. Obviously, you could just do something like return the first match, and then delete all characters up to and including that starting character, and perform another search, but I'm hoping for something more efficient.
