I did my time with rsruby, rinruby and Rserve-Ruby-client. In retrospect I should have trusted the Rserve-Ruby-client readme which details the problems with rsruby and rinruby. rsruby – dealbreaker is that this is not stable, there are a few other downsides including complex data conversions and compilation issues but enough said. rinruby – slow, but more importantly fails …
Cleaning up some systems and looking for packages that are no longer maintained. apt-show-versions | grep ‘No available version in archive’ I was amazed at some of the old packages on the systems, like libraries related to Gnome 2. This catches things that other methods like deborphan won’t.

Here is what I did on my Ubuntu 12.04 workstations that was very easy though not trivial to figure out. sudo gem install linecache19 –pre …

First install build dependencies. This list may not be complete as some necessary libraries and tools may have already been installed on my test machines.

I ran into this problem where I was getting “uninitialized constant” errors when running rake tasks. These are tasks which had been working and I verified that the proper paths were set (eager_load_paths). When searching I saw information about config.threadsafe! being a problem so I disabled it and the problems vanished. However, I wanted to …
I did some research and found a lot of discrepancy among recommendations for the decimal precision when doing geocoding. Some say you only need 4 digits of precision and others suggest up to 15. In my own testing the best results seemed to be with 6-digits and SQL type of PRECISION(9,6) for latitude and longitude. …
