I like the bittorrent client Vuze but it crashes on some of my machines after a while.
I wrote a monitoring script that is checking if vuze is running. If vuze dies, the script restarts vuze automatically.
The source code is here: https://github.com/jabbalaci/Vuze-Restarter .
I wanted to test the status of my Dropbox client from the terminal. Actually, I wanted to write a script that executes an action when my Dropbox folder is fully synced. So I wanted to test the status if it’s “working” or “synced”.
I found the solution here. It turned out that Dropbox has an official command-line script that can do this and much more. First, get it:
wget -O ~/dropbox.py https://www.dropbox.com/download?dl=packages/dropbox.py chmod u+x ~/dropbox.py ~/dropbox.py status
This is a Python script, written in Python 2, thus I modified the first line to be “
This script can do several things for you:
$ dropbox.py Dropbox command-line interface commands: Note: use dropbox help to view usage for a specific command. status get current status of the dropboxd help provide help puburl get public url of a file in your dropbox stop stop dropboxd running return whether dropbox is running start start dropboxd filestatus get current sync status of one or more files ls list directory contents with current sync status autostart automatically start dropbox at login exclude ignores/excludes a directory from syncing lansync enables or disables LAN sync
Some years ago I wrote a simple script to get the public URL of a file in my Dropbox folder. This script can do that too with the “puburl” command.
There is a command line interface for Reddit called “rtv” (reddit terminal viewer). It’s written in Python, so you can install it with
Here is a short youtube video on how to use it.
You have a video and you want to create an animated gif from a part of it.
from moviepy.editor import * clip = (VideoFileClip("frozen_trailer.mp4") # input video .subclip((1,22.65),(1,23.2)) # part to extract, where 1’22.65 means 1 minute 22.65 seconds .resize(0.3)) # resize to 30% of the original clip.write_gif("use_your_head.gif") # output animated gif
Example 2 (cropping):
kris_sven = (VideoFileClip("frozen_trailer.mp4") .subclip((1,13.4),(1,13.9)) .resize(0.5) .crop(x1=145,x2=400)) # cropping: remove left-right borders
Example 3 (play forward and backward):
def time_symetrize(clip): return concatenate([clip, clip.fx( vfx.time_mirror )]) clip = (VideoFileClip("frozen_trailer.mp4", audio=False) .subclip(36.5,36.9) .resize(0.5) .crop(x1=189, x2=433) .fx( time_symetrize )) # the effect is added here

I have a desktop machine at home with a Windows 2007 virtual machine. I mainly have it because of Powerpoint. Recently I prefer to work on my laptop in the living room. Today I needed Powerpoint, so I decided to copy the whole Windows virtual machine and put it on my laptop. The only problem is that it was 67 GB and I didn’t have that much space on my external HDDs :(
Don’t panic. On my desktop machine I entered the folder that I wanted to copy and started a web server:
python -m SimpleHTTPServer
ifconfig” I checked the local IP address of the machine, it was
On my laptop I opened a browser and navigated to “
http://192.168.0.53:8000“. All the files I needed were there. Since I’m lazy and I didn’t want to click on each link one by one, I issued the following command (tip from here):
wget -r --no-parent http://192.168.0.53:8000
The download speed was about 10 MB/sec, so it took almost 2 hours.
You have a media file (audio, video, image) and you want to get some detailed information about it: duration, bit rate, resolution, etc. How to extract these pieces of information?
Use the MediaInfo project. You can install it via your package manager and you will get a command called “mediainfo”.
