Redis →
Redis is what is called a key-value store, often referred to as a NoSQL database. The essence of a key-value store is the ability to store some data, called a value, inside a key. This data can later be retrieved only if we know the exact key used to store it. We can use the command SET to store the value “fido” at key “server:name”:
SET server:name “fido”

websockets
The Websocket API is a new implementation for html5 to support bi-directional communication with server side processes. This is good news since realtime interactions with webservers have not been a very exciting experience so far, although AJAX and XmlHttpRequests have enabled browser based web applications to quickly exchange data with a server. Websockets will be able to keep a direct connection...

I started to revive an older version of a processing webserver (sHTTP) i wrote a while back which allows to control processing applications through a website based interface. First thing to get replaced was the server implementation with NanoHTTPD by Jarno Elonen and Konstantinos Togias. Works smooth and well, but I am giving my considerations another round of thought and will look into node.js...

Android Adventures, part 6: Building a signed .apk from Processing | AK Eric
“Processing makes it really easy to “Present” a sketch to your Android phone via it’s “Present” button. This creates a special unsigned apk that can run on your specific device, but isn’t distributable (and I can’t even find it) to others. There is no easy way (yet) to get these sketches to other users via the...
