Tea Time at Rackspace SF

One of the Rackspace teams here in the SF office doesn't to standups; it does "tea time" instead. A delightful change, to be sure. One of my coworkers published a Rackspace blog post about this today.

More than a gratutious reblog, I wanted to highlight this bit of lovely coincidence I came across while reading Turing's Cathedral last night:
"Afternoon tea— a ritual introduced at Fine Hall by Oswald Veblen, who, according to Herman Goldstine, “tried awfully hard to be an Englishman”— was served on real china daily at exactly three o’clock. According to Oppenheimer, “tea is where we explain to each other what we do not understand.”

Dyson, George (2012-03-06). Turing's Cathedral: The Origins of the Digital Universe (p. 90). Knopf Doubleday Publishing Group. Kindle Edition. 
The part of the book where this quote occurred was discussing Fine Hall which was built for Von Neumann's computer team at the Princeton Institute for Advanced Studies.

And, yes, tea time is a great time for our team mates to explain to each other what they don't understand.

Cruising HTTP with LFE

In the last post, you learned how to get LFE running on Ubuntu. This one will give you some insight into how LFE can be used in something approaching real-world problems. In the next post, we're going to jump back into the lambda calculus, and we'll see some more LFE shortly after that.

Because Lisp Flavored Erlang is 100% compatible with Erlang Core, it has access to all the Erlang libraries, OTP, and many third-party modules, etc.  Naturally, this includes the Erlang HTTP client, httpc. Today we're going to be taking a look at how to use httpc from LFE. Do note, however that this post is only going to provide a taste, just enough to give you a sense of the flavor, as it were.

If you would like more details, be sure to not only give the official docs a thorough reading, but to take a look at the HTTP Client section of the inets Reference Manual.

Note that for the returned values below, I elide large data structures. If you run them in the LFE REPL yourself, you can view them in all of the line-consuming glory.

Synchronous GET

Let's get started with a simple example. The first thing we need to do is start the inets application. With that done, we'll then be able to make client requests:

New Advogato Features

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.

Keep up with the latest Advogato features by reading the Advogato status blog.
