Using strace and lsof to debug blocked processes

You can use strace on a specific pid to figure out what a specific process is doing, e.g.:

strace -fp <pid>

You might see something like:

select(9, [3 5 8], [], [], {0, 999999}) = 0 (Timeout)

To set up search history backward in inputrc add these settings:

This will add you ctrl + up and ctrl + down to complete command partial. But if you change your mind and want to jump different command you can simply do it by using up and down without the ctrl.

/etc/inputrc:
    "\e[1;5A": history-search-backward
    "\e[1;5B":      history-search-forward

Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.

From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?

The Ruby Way! (Fun)
