NOAA CSC and USCG do a lame job with Marine Cadastre AIS

This is a serious waste of our tax payer dollars.  Public data about vessel location is being removed from datasets.  This stuff is broadcast in the clear for anyone to receive.  And what do they mean by "encrypted"?  Did they just run a hash (e.g. md5) function on it?  If that's the case, if I we can figure the hash function, it's trivial to build a rainbow table style lookup.  Once that's done, there are lots of sources of MMSI to vessel name and call signs.  Oh, and by the way, it's 2015 and only 2009, 2010, and 2011 are available.  And then they publish it in the ESRI File Geo Database (FGDB) format that really isn't open.  And I don't really feel like getting a username and password again (or maybe my old one still works).  Sigh.

"Note: Ship name and call sign fields have been removed, and the MMSI (Maritime Mobile Service Identity) field has been encrypted for the 2010 and 2011 data at the request of the U.S. Coast Guard."

Java and Eclipse on the mac

At one time, Apple seemed into Java and things were only slightly painful.  Then Java went out of favor with Apple and things went from bad to worse.  I downloaded the 64bit Mac build of Eclipse and got this after cd /Applications and tar xf ~/Downloads/eclipse-standard-luna-SR1-macosx-cocoa-x86_64.tar.gz and then double clicking the Eclipse icon.

I tried editing /Applications/eclipse/ to look like this:

Looking at my system, I find this for java:

ls -l /Library/Java/JavaVirtualMachines
drwxr-xr-x  3 root  wheel  102 Apr  4  2014 jdk1.7.0_51.jdk
drwxr-xr-x  3 root  wheel  102 May  7  2014 jdk1.7.0_55.jdk
drwxr-xr-x  3 root  wheel  102 Jul  9 13:46 jdk1.7.0_60.jdk
drwxr-xr-x  3 root  wheel  102 Jul 30 13:27 jdk1.7.0_65.jdk
drwxr-xr-x  3 root  wheel  102 Sep 18 05:50 jdk1.7.0_67.jdk

drwxr-xr-x  3 root  wheel  102 Dec 10 08:45 jdk1.7.0_71.jdk

But no luck.  I finally found that this success:

cd /Applications/eclipse/
./eclipse -vm /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home/bin/

And now I have eclipse running:

So I now have Eclipse Luna Service Release 1 (4.4.1) Build id 20140925-1800 on Mac OSX 10.9.5 with XCode 6.1.1.  It took me way too long to get this figured.
