JNLP files and WebStart

I don't know how some memes get started but somewhere along the line I picked up the meme that Web Start JNLP files are hard to build. Up until this weekend I had never sat down and created a JNLP file so I had no data one way or the other. Well I can now categorically reject that meme. For a basic Java application it's a piece of cake.



If you've ever describe something via XML: RSS, FOAF, etc..., it's just like that. There's probably some more richness and complexiy in the spec that I don't know about, but that's OK, whatever it is I currently don't need it. This is the entire file I needed to get my game working via Web Start.

The game is not close to being done, but you can now load it and move the units around some; enough to see where it's heading. If you want to see the JNLP file in action look here and click on the ship icon on the bottom of the page.

Shark Crackers

The movie Jaws has been a fan favorite for 30 years. A lot has been written about the impact Jaws had on the movie making business and summer swimming habits but there's one aspect of the movie that's seldom been discussed, the impact Jaws had on the image of the saltine cracker. Before Robert Shaw's Quint, a cracker was a bland cake of baked flour only good as a surface to hold peanut butter or cheese, but not after. Quint elevated the cracker into the snack of sailors and shark hunters. What man has not wanted to calmly snap chunks of a cracker while saying the words: Y'all know me. Know how I earn a livin'. I'll catch this bird for you, but it ain't gonna be easy. Bad fish! Not like going down to the pond and chasing bluegills and tommycocks. This shark, swallow you whole. No shakin', no tenderizin', down you go. Much like the Eucharist is a symbol of Christ in the Catholic tradition, in Jaws, the cracker forms the edible representation of the

Running roughshod or ripshod

A common euphamism for political power abuse is saying someone or organization has ' run ripshod ' through the land. I was going to use the phrase myself the other day when I realized I had no idea what ripshod meant. I searched around and found many other users but no place that could define the word. This started me thinking that perhaps every example I found was just a perpetuation of a common mistake. I tried aother variations on the phrase and finnally hit upon a more common usage: run roughshod. The words roughshod and ripshod don't really sound the same but people use them in the same manner in similar contexts. Does anyone know the proper usage?

Axis, Axes, Axii?

While writing another post (it will probably follow this one) I needed to pluralize axis. None of the guesses I came up with passed the spell checker so I Googled it. The first hit I got was from a drafting company. (Interesting aside: word order matters in Google more than I realized - searching for "plural axis" didn't get the same dictionary oriented results as "axis plural") According to these folks the answer is: Grammatical Note : The plural of axis is axes. Some radical etymologists insist that the plural form of axis is axii, but that is only if there are three or more; One axis, two axes, three axii. The word axii, however, still doesn’t pass the spell checker, so perhaps getting grammar lessons from a drafting company isn’t such a great idea. More legitimate authorities simply list axes as the plural. If you do visit the above link to drafing company, can you answer me a question, what the heck are those diagrams depicting. I
