Context I'm compressing ~1.3 GB folders each filled with 1440 JSON files and find that there's a 15-fold difference between using the tar command and Python's built-in tarfile library on macOS or Raspbian 10 (Buster) Minimal working example This script compares both methods: #!/usr/bin/env python3 from pathlib import Path from subprocess import call import tarfile fullpath = Path("/Users/user/Desk

I noticed that my Python application is much slower when running it on python:2-alpine3.6 than running it without Docker on Ubuntu. I came up with two small benchmark commands and there's a huge difference visible between the two operating systems, both when I'm running them on an Ubuntu server, and when I'm using Docker for Mac. $ BENCHMARK="import timeit; print(timeit.timeit('import json; json.d

I've OpenSSH 7.6 installed in Windows 7 for testing purposes. SSH client & server work just fine till I tried to access one of my AWS EC2 box from this windows. It seems like I need to change the permission on the private key file. This can be easily done on unix/linux with chmod command. What about windows? private-key.ppm is copied directly from AWS and I guess the permission too. C:\>ssh -V Ope

After reading things here and there on the internet, I came up with following ~/.tmux.conf However when I open vim and try to scroll with mouse tmux scrolls through its scroll buffer instead of sending the scroll command to vim. Is there a workaround? Following is my config: set-option -g default-shell /bin/bash se

In my .mp4 file the audio delay is -3840 ms. I synced it in KMplayer, and I don't want to use MKVGUI to make a .mkv file. I just need to delay the audio by 3840 ms, everything else should be left intact. What would be the right command to accomplish this using ffmpeg? I would appreciate your help.

Instead of providing a fixed frame rate to FFMPEG/libx264 (-r/-framerate), I would like to specify a variable frame rate with a MAXIMUM value, and allow libx264 to down the frame rate as it sees fit. The idea here is to get extra compression when there is something like an extended still frame (which happens A LOT in my source videos). I realize that a predictive or bidirectional MPEG frame will c

I'm looking for a command or script which returns an unused port on my ubuntu linux system. I have look on internet and the only thing I find is about the used/Listen port with the nestat command. Apparently something with the netstat command will work but don't know what exactly. Any idea how? Thanks.

I'm using iTerm 2.1.4 and Tmux on OS X Yosemite. I'd like to be able to scroll my iTerm windows up and down but I'm not sure what controls scrolling. Does tmux control scrolling when I use it with iTerm or does iTerm still control scrolling? I've tried using the various keys that are supposed to scroll iTerm but all I get are "~~~~~" characters on the command line. How do I scroll with this setup?

It used to remember the passphrase, but now it's asking it to me each time. I've read that I need to regenerate the public key with this command, which I did: ssh-keygen -y -f id_rsa > id_rsa.pub but it didn't fix anything. How can I make macOS remember my passphrase again?

Process Explorer is able to show the effective IO priority of a given thread, but not change it. Seeing as IO priority support is a comparatively new feature, most programs don't set their own IO priorities. It appears that by default the IO priority is derived from the thread priority (rather than process priority), which Process Explorer can't modify either. Are there any other tools out there t

I'd like to be able to SSH into this Ubuntu instance, but although I have openssh-server installed and configured (and listening on port 2200), when I try to ssh to "localhost:2200", it tells me "Server unexpectedly closed network connection".

I have a fast computer (quad-core i7, 3.5 Ghz, 24 GB of RAM, Windows 8.1) and I installed a new hard drive less than a year ago that was supposed to be as fast as you could buy for an HHD and not an SSD. On boot, the computer is extremely slow for about 20 minutes (literally 20 minutes). Nothing will load. Opening programs will just hang. Went into Resource Monitor and found that my disk I/O is at

The characters ^[[37m and ^[[0m are part of the ANSI escape sequences (CSI codes). See also these specifications. Using GNU sed sed -e 's/\x1b\[[0-9;]*m//g' \x1b (or \x1B) is the escape special character (GNU sed does not support alternatives \e and \033) \[ is the second character of the escape sequence [0-9;]* is the color value(s) regex m is the last character of the escape sequence Using the m

There is a new folder full of installers located at C:\ProgramData\Package Cache\. I believe this is from Visual Studio 2012 RC. Can I delete these gigabytes of data without consequences? Are they all temporary files? It's a beta product so I'm not sure there is much information out there about this folder.

I am working on a web application that is using redirects (for pretty URLs). I am trying to debug logic in the way the redirects are working. However Google Chrome keeps remembering the redirects and even after I change the code, redirecting the same way. This is making it very hard to troubleshoot. For example if I redirect /this to /that, then change my code to NOT redirect /this anymore. Google

I know that it's possible in tmux to join a window as a pane, but is it possible to move a pane to it's own window (tab)? I tried searching it up the man page but couldn't find it. I guess it is possible doing it through a shell script, but is there some other, more elegant way?
