Throwable technology. Not so silly after all. ibm.biz/bluemixgaragelondon @holly_cummins

Remind you of anything? ibm.biz/bluemixgaragelondon @holly_cummins

Not really. It’s very lumpy, isn’t it? ibm.biz/bluemixgaragelondon @holly_cummins

Software faults can be corrected without re-typing the whole program. ibm.biz/bluemixgaragelondon @holly_cummins

Computers are getting small enough and cheap enough that they’re almost disposable. It’s possible to sock computers away almost anywhere, and to connect almost anything to the internet. At the same time, the Java stacks that we know and love are also getting lighter and cheaper. That combination means it’s possible to put a full spec-compliant Java EE server on ridiculously cheap hardware, and then throw it around the room without worrying too much about breaking stuff.
