NeuroSky Bluetooth still not reliable on Mac OS

I am still getting frequent disconnects with the NeuroSky headset on my Mac. I was looking forward to the release supporting eye blink detection.

Maven2 environment for building naws3

June 28th, 2010 No comments

I wish I had adopted Maven earlier. I was  surprised at how well it all worked. It took a few  days to go from no knowledge of Maven to a system that builds naws, generates docs and supports a Maven repository for naws3 users. These links were very helpful. Some of the things that caused me lose time were:

  1. Tried to configure NetBeans remote repositories using pom files. That did not work you need to use the NetBeans repository browser and for some reason I could not find it. The Maven repository browser in NetBeans is not available from the project nodes, it is under Window / Other / Maven Repository Browser. More details can be found here.
  2. The site setup for ssh took some time because of an error in The Oreilly Maven book, it used publicKey instead of privateKey for the  key on page 318
  3. naws has some files that use the IAIK security libraries, I spent quite a bit of time trying to figure out how to have the files there but not compiled by NetBeans. I was hoping that Maven would pre-process the files NetBeans includes in a  project.  I don’t think this is possible so I moved them out to a separate project not ideal
  4. setting properties for Maven is still a mystery so I am just using settings.xml (-X doesn’t tell you what properties file it is reading and in what order)

The still being worked on Maven generated site can be found here: digiorgio.com/naws3 and the repository with the required jars can be found here digiorgio.com:8082/artifactory/naws3/ naws3 is hosted on kenai for source code management, ans issue tracking. CI, static analysis, dynamic analysis and OpenGrok interfaces are on digiorgio.com.

If I were creative I would make a movie about the nosql people trying to convince you that approximate and different answers are ok. Or maybe we should bet everything on one platform because it is just too hard to have something that runs on lots of platforms with some effort. Forget the platforms just do it all from the big server and use the browser — that’s it — the browser and AJAX is answer to all questions.  ;)

Cablevison’s new policy of requiring a tuner

June 22nd, 2010 1 comment

Recently my cable company, Cablevision, stopped broadcasting signals that did not require a cable tuner. I was thinking of dropping them without considering how much worse some of the others may or may not be but it does not matter, I do not have a choice, only one provider. It does seem unfair that cable companies are not forced to share wires like the phone company and energy companies are forced to. There is one nifty thing about Cablevision the Internet service is OK on the download but quite slow on the upload, I do not believe the upload number below. This website digiorgio.com  hosted on the Cablevision service  is dreadfully slow.
