LaTeX in WordPress posts

It’s easy to use formatting commands in WordPress post.  See the explanation at: http://en.support.wordpress.com/latex/

Here is a test:

I am migrating my pages from WordPress to Octopress for many reasons, one being better MathJax support, another being the opensourcedness of Octopress. My new page is here.

my public pgp key

If you want to email an encrypted message or file to me, please use my public key.

If you use gmail, I highly recommend the Mailvelope chrome extension. With it you can import public keys and send encrypted messages directly from gmail.

Below are two ways to send me encrypted stuff. If anything is not clear, please post a comment at the bottom of this page.

1. Using an email app or plugin (like Mailvelope)Copy the pgp block below and paste it into your email client’s key manager:

   -----END PGP PUBLIC KEY BLOCK-----

2. From the command line  Download my public key file, William_DeMeo_pub.asc, change to the directory where you saved the file and enter the following command:

   gpg --import William_DeMeo_pub.asc

   (If the gpg command above doesn’t work for you, perhaps you need to install the gpg program. See the instructions here.  Ubuntu users can simply do `sudo apt-get install gnupg`)

   If you’re new to gpg, a great, short and simple guide is at http://www.madboa.com/geek/gpg-quickstart/

   Once you have my public key imported, then you can encrypt a file so that only I can open it with the following command:

   gpg -e -r 'William DeMeo' filename

   To send encrypted email messages, I recommend installing the Mailvelope.com chrome extension and importing my public key into your list of public keys, again by cutting and pasting after selecting “import” from the mailvelope menu. Then you can even use gmail to send me encrypted messages (that the NSA might have trouble reading… but probably not).
