Tricky Shoes (Ruby pt. 14)

Finally found an explanation for the weird behavior of variables in Shoes. There is a fork of Shoes called Green Shoes that combines Ruby with Ruby-GTK to redo-shoes. Actually a neat idea since it extends Shoes to a larger windowing system. In the manual for the project I found something interesting about Shoes.

In Shoes each window is the unit. The stack blocks are weird. They look like normal blocks but are sub-set block of the window unit. The command para (for paragraph) which displays the text on a block is really self.para and self is from the Shoe's window. Additionally all instance variables inside and outside stack blocks, are held inside the window unit too. This is key and not well explained in the documentation on Red Shoes.

Still haven't figured out how to make my temperature conversion GUI program and I'm seriously tempted to just learn Xcode and code it on the Mac with Macruby, but Shoes with all it's faults is cross platform and that has huge advantages. And Xcode is not as easy to learn.

One good thing about Green Shoes is that it seems to be under active development where Shoes only has one developer (Steve) as far as I can tell and he's in grad school now. And Green Shoes being based on GTK it is likely to be far stabler than normal Red Shoes which crashes and drives up processing threads on my Mac fairly often.

What Medieval Economics can teach us about tariffs.

As a teen, I used to play Dungeons and Dragons (D&D) with my friends. This started an interest in the medieval period that led to me taking a medieval history class in college just to understand the period more. Over the years I've also read great books like " Dungeon, Fire and Sword " about the crusades (I recommend the book) and yet with all that knowledge it wasn't until recently that it occurred to me I had a completely wrong understanding of economics in the Medieval Period. "Viking helmets, sword and footwear" by eltpics is licensed under CC BY-NC 2.0 In my D&D games, players who are adventures battling monsters and creatures would need equipment and on the trips to town, they'd get resupplied with their adventuring necessities. I'd run these moments referencing my imagination of what it must have been and fantasy books I'd read. There be an inn with a raucous bar, a gruffly black-smith, if a city also a weapon and armor sm...

Great iPhone Apps

As a companion to my blog on Windows utilities, here are two paid apps on the iPhone that I consider so fantastic that are must buys in my opinion. -Easy Calendar ( $1.99 ) The iPhone Calendar is one of its weakest features in my opinion. I miss the clear Black Berry calendar on my pearl whenever I had to use it. This app makes the calendar not only easy to use but way more useful, I see my week laid out for me with an easy ability to push things to other days (rather than having to re-enter the appointment). This app has completely re-made the way I organize things. I'm way more organized and rarely miss appointment now. This app is a steal at it's prize. No other app adds such simple functionality to the iPhone like this one does. It's like my secret organizer helper. -Sleep Cycle ( $.99 ) I tried out this app because it was recommended on Tim Ferriss's books . I had seen this app before when it came out and thought it was intriguing, but it was way expensive. N...

Indie Games

I've played a few really great indie games recently and would like to share a bit about them. None of these games are brand-new and all are available in both Mac and PC versions. 1. Aquaria Aquaria is a gem of a game for those that loved the original metriod games. In Aquaria you play a young mermaid creature that decides to explore her world beyond her home waters. In doing that you guide her through many adventures that reveal a bit about her world. The game is visually beautiful and the game mechanics, though simple, are very nice. You can play the whole game with a mouse if you wish though gamepads are supported too. In the game you access special abilities by singing different songs. It is a neat concept.  The game was made by an indie outfit of mainly two people out of Canada. But it feels much more than that. It's very big like an underwater version of Castlevania: Symphony of the Night, with multiple treasures to collect and many secrets to uncover. It is available for ...
