Why not: from Common Lisp to Julia

This article is a response to mfiano’s From Common Lisp to Julia which might also convey some developments happening in Common Lisp. I do not intend to suggest that someone coming from a Matlab, R, or Python background should pickup Common Lisp. Julia is a reasonably good language when compared to what it intends to replace. You should pickup Common Lisp only if you are interested in programming in general, not limited to scientific computing, and envision yourself writing code for the rest of your life. It will expand your mind to what is possible, and that goes beyond the macro system. Along the same lines though, you should also pickup C, Haskell, Forth, and perhaps a few other languages that have some noteworthy things to teach, and that I too have been to lazy to learn.

/I also do not intend to offend anyone. I’m okay with criticizing Common Lisp (I myself have done it below!), but I want t

GPG - SSH setup

Generating the master key

Here we create the master key. We want only Certify capability: we use the master key only to create the subkeys, Sign - Encrypt - Authenticate capabilities will be assigned to the subkeys.

Run the following command to start the master key generation process. Select the set your own capabilities creation process (type 8)

  ▶ gpg --full-generate-key --expert

Sometimes it is useful to route traffic through a different machine for testing or development. At work, we have a VPN to a remote facility that we haven't bothered to fix for routing, so the only way to access a certain machine over that VPN is via an SSH tunnel to a machine that is reachable over the VPN. Other times, I have used this technique to test internet-facing requests against sites I am developing. It is pretty easy, and if you don't use firefox regularly, you can treat Firefox as your "Proxy" browser and other browsers can use a normal configuration (Although you can also configure an entire system to use the proxy, other articles exists that discuss this potential).

1. Open a terminal

The following shell transcript shows how to:

• Create a GPG key
• Create a pass database
• Add git support to the pass database
• Create a remote git repository
• Push the pass database to the remote git repository
• Fetch and display your passwords from another host

It is assumed that the pass package has been installed on both the first and second computers.

# A graph with 32 vertices takes under one second, so it's not the fastest.
