Abort a slow flush to disk after write?
Is there a way to abort a python write operation in such a way that the OS doesn't feel it's necessary to flush the unwritten data to the disc? I'm writing data to a USB device, typically many megabytes. I'm using 4096 bytes as my block size on the write, but it appears that Linux caches up a bunch of data early on, and write it out to ...

EntityManager does not update on flush()

bash: flushing stdin (standard input)
I have a bash script that I mostly use in interactive mode. However, sometimes I pipe in some input to the script. After processing stdin in a loop, I copy a file using "-i" (interactive). However, this never gets executed (in pipe mode) since (I guess) standard input has not been flushed. To simplify with an example: #!/bin/bash while ...

How often does python flush to a file?
I was wondering how often python flushes to a file. Also wondering how often python flushes to stdout. I believe python flushes to stdout after every new line but that being said, if you overload stdout to be to a file does it flush as often as stdout or how often it flushes to a file? Anyways thanks! And sorry for the pretty simple que...

I have a program that uses curses, and then returns to the main script for further processing. After it returns, my subsequent output to stdout does not appear until there's a large amount of it (e.g. thousands of bytes). I've reduced the problem to a very simple program that fails reliably: import curses import time curses.initscr() ...
