If you are a command-line lover, then it is likely that ipython is already
one of your friend. In Python, help() is our swiss army knife. However, always
having to embrace commands with parathesis, ( and ), is really a hassle!
Wouldn't it be great if we could simply invoke like this?

I was using rsync -e "ssh" to transfer files between local and remote computer. If I want to transfer a file from remote to local, the command will be like rsync -av --delete -e "ssh" user@ip:/path/to/fileA /home/user/folder/. One day, however, I thought I could transfer a remote folder /path/to/folderA/ to my home /home/user/. After running the command, I found that it started erasing my home directory! Since Linux has disk encryption by default, I failed to rescue those files eventually ;(
My bash history was stored as ~/.bash_history. One day, I was running a huge apt upgrade. It took me plenty of time, so I left it and went to sleep. However, I forgot that my laptop was in battery mode. So eventually, the battery ran out, and my computer experienced an abnormal power off, which resulted in me having a corrupted bash_history. I have no backups, so I lost all my bash history ;(

We are using CTFd for in-class projects. Here I share some modifications on CTFd for better in-class managements.
I am a big fan of Monokai theme and colors. This color scheme is basically the same as Agila's Monokai Extended color scheme, except that all gray backgrounds have been replaced with a nice looking brown one! :) (plus issue #43 been fixed)
Note that I only demonstrated the Color Scheme, not the Theme. The theme I used was Spacegray Eighties.
[Dot][] is a graph description language in extensions .dot or .gv, and can be read by programs such as Graphviz ([try it online][]). However, it's syntax is too complicated for the goal of generating a simple control-flow graph, and is not very well human readable. Therefore, I defined a new language, prettydot, for this purpose.
