Papa Blox Gingerbread man

Here is the first pushmo puzzle I got from Papa Blox. All of the puzzles have additions to make them solvable or I would not be able to publish the QR codes. In this puzzle, I added the flag.

linux webcam

I run ubuntu linux, sometimes. To get my built-in webcam to work, I need to run "gstreamer-properties". I close the window and it works. I like to use cheese webcam booth.

I was considering going out with Mrs. Normal's daughter, Abigail, until I discovered she was Abby Normal.

Ruby on Rails with Ubuntu

Ubuntu wants to make it to the masses, but even a developer has trouble building the developer tools.

I am talking about Ruby on Rails. First off, the Ruby included in Ubuntu is jruby. The real ruby needs to be installed. That is fairly easy with an apt-get.

Then, to install sqlite3, the libraries are installed, but not the development package. That needs to be done.

gems has to be installed which can also be done with apt-get
But, the gemspec files are wrong (bad date format) and this causes a bunch of errors pointing at "tilt-1.3.3 not found" (but it is there.)

We "gem install rails". That works.

Once everything is ready to run, then rails complains that there is no javascript runtime.

But that is not the only thing. node.js is the javascript runtime, but it won't compile unless it has openssl. Openssl is there, but not the development package.

So, now that the gemspec files are fixed, the openssl dev, sqlite3 dev, gems, ruby are installed, we can finally run rails.

Whew!
