I have directories that contains ‘x..’ characters such as ‘x00’ : and I want to rename them without these, since when I copy those files to windows they become unusable.

Run interactive Bash with popen and a dedicated TTY Python
I need to run an interactive Bash instance in a separated process in Python with it’s own dedicated TTY (I can’t use pexpect). I used this code snippet I commonly see used in similar programs: But when I run it I get the following output: Strace of the run shows some errors: The code snippet seems pretty straightforward, is Bash
Multiprocessing: use only the physical cores?
I have a function foo which consumes a lot of memory and which I would like to run several instances of in parallel. Suppose I have a CPU with 4 physical cores, each with two logical cores. My system has enough memory to accommodate 4 instances of foo in parallel but not 8. Moreover, since 4 of these 8 cores
Pairing bluetooth devices with Passkey/Password in python – RFCOMM (Linux)
I am working on a Python script to search for bluetooth devices and connect them using RFCOMM. This devices has Passkey/Password. I am using PyBlueZ and, as far as I know, this library cannot handle Passkey/Password connections (Python PyBluez connecting to passkey protected device).

Unable to fake terminal input with termios.TIOCSTI
Most of the code samples I’ve seen are trying to read from stdin without local echo. To do this they modify the “local modes” flag to remove the setting to “Echo input characters”. I thought I could just modify the “input modes” flag to TIOCSTI which is for “Insert the given byte in the input queue.”. However, even though I
