The Future is for Elephans!

Distributed computing has been challenging the smartes brains for decades. Until recently, it has been locked away from ordinary IT engineers in geek labs. However, I believe that frameworks like Hadoop will be used a lot more in the near future.

I have found a few useful presentations about MapReduce (or Hadoop), Google File System (or HDFS), BigTable (or HBase) and more:
Enjoy!

Minion - new Java search engine from Sun labs

It seems that there will be a new open source (GPLv2) search engine revealed for Java soon. It is called Minion and Stephen Green (aka The Search Guy) has just started blogging about it. He has already published few posts and it seems that Minion has some interesting concepts:
  • For example it can store the Date as Date (as opposed to Lucene which can store Date only as a String).
  • Also it seems to be conveniet for stream indexing (indexer is stateful).
  • Every document in index has an unique key and it never changes - updates of documents are then handled automatically under the hood (as far as I know Lucene can not offer such luxury).

It is hard to create good and unique logo design

While I was searching for some stuff on the internet I came across the following add from Adobe:


It seems to be an Adobe ON AIR Tour Europe add. Normally the adds do not catch my attention but this one is an exception because the visual style is so close to ON Semiconductor corp (my employer) logo design:
Also other horizontal Adobe campaign logo seems to be interestingly close to ON Semiconductor design:


ON Semiconductor logos can be found here.
