Web Fundamentals by James Ward (at 8:30 this morning, groan) was fabulous. In a dense hour he laid out what hours of googling and reading books (online and print) has failed to give me. He works for TypeSafe and they have some nice looking web tools which I am now inspired to try. It's a 200 MB download... good thing the wireless works.
Sun SPOTs are dead. When current stock is gone no more will be made. This is the final chapter in a sad story. SPOTs could have been the Arduino for the Internet of Things. But at a commercial license fee of $100K, what can you expect? Suppose Arduino had a $10K license fee for commercial use? It would have flopped too. Now SPOTs are open source, but no one seems to care. There are better options out there: you guessed it, mostly based on Arduino. $400 gets me two wireless SPOTs and a base station, or for $75 I can get a pair of Arduino WiFi Spark Core devices.
You never have to go more than half a block in San Francisco to get a decent latte. And at JavaOne you can get as many as you want for free in the "Buzz Shack". Someone got this right!
This is one aspect of Arduino which helps make it popular: the whole Arduino IDE and its libraries are open source, and since the code is all standard C/C++ and the underlying compiler is GCC, how badly can you be stuck in the unlikely event the Arduino.cc developers abandon further work? If we only have access to the binary releases of the JVM for ARM, what do we do if Oracle abandons the effort?
