GUI Maze of Death (Ruby Pt. 13)

One of the challenges of programming is interacting with the user. The terminal presents few options. I'm working on a temperature conversion program. Which so should use radio buttons. You enter the degrees enter the number, click on the degrees you want to convert to and the answer pops out. Cool so I thought this would be the perfect opportunity to learn Shoes. A lightweight GUI for Ruby. But no.

Gui programming is like trying to find your way through a maze. Except blindfold, dizzy and no minotaur motivation.

This is not really a commentary on Shoes, which is actually quite easy, but on the tutorials and resources to learn it. In that there are so few and they tend to assume a high level of programming mastery.

Designing the Gui is not exactly easy but the real maze is trying to link it to a the heart of the program. I've been trying to write a program that changes the temperature from Fahrenheit to Celcius thinking this was a great place to use radio buttons or list to avoid writing something like please enter "F" and "C" to convert temperature and trying to sanitize what people write. With radio buttons I know what they're inputting.

I got as far as getting Shoes to launch a window with drop down menus for selecting the temperature (Fahrenheit or Celcius) and a convert button, but you press it and nothing happens, and I've no clue why. I need to find some better tutorials on this... Thankfully it looks like the same people that run the online course of Ruby I'm taking also will do a Ruby with Shoes class, but it's not available yet.

Contrasting Styles of Writing: English vs. Spanish

There is interestingly enough a big difference between what's considered good writing in Spanish and English . V.S. Naipul winner of the 2001 Nobel prize for literature publish an article on writing . In it he emphasizes the use of short clear sentences and encourages the lack of adjectives and adverbs. Essentially he pushes the writer to abandon florid language and master spartan communication . This is a desired feature of English prose , where short clipped sentences are the norm and seamlessly flow into a paragraph. In English prose the paragraph is the unit the writer cares about the most. This is not the case in Spanish where whole short stories (I'm thinking this was Gabriel Garcia Marquez but maybe it was Cortázar) are written in one sentence. Something so difficult to do in English that the expert translator could best manage to encapsulate the tale in two sentences. The florid language is what is considered good writing in Spani...

Building my own home.

I've decided. I want to build my own home. There is something special about building your own things. I built a desk for my tiny room when I first moved to L.A. My room was so small that I had to sit on the bed to use the computer so I build a high desk so I could sit on the bed and work on the computer. My roommate Trentity helped me cut the ply-wood to the right side. I still have that desk. It now sits on the living room covered by a cloth hiding the surplus of costume parts my current roommate Sean uses in his creations. Learning to build and fix things continue. And the feeling of satisfaction from fixing even small things is great. So a few years ago I heard on the NPR program the Story about a couple of educators that moved to a tent in their back-yard so they could rent their house and afford to send their kids to college. They had a special type of tent called a yurt and cooked and showered in an RV they had parked next to it. I thought I could do that. Housing in Lo...

My Fake Resume

Inspired by the over aggrandized bio of Joseph Rakofsky I want to write my own. If you don't know who he is; Joseph Rakofsky is a lawyer who earned a mistrial for a criminal client due to his (alleged) incompetence as reported on the Washington Post . There has been quite a few commentaries on his "Streisand-house" approach of suing all the bloggers and even the Washington Post and American Bar Association for reporting his (alleged) ineptitude. ("Streisand-house" is what happened to Barbara Streisand who wanted to have a picture of her mansion removed from the internet and she sued to have it removed. Unfortunately suing requires the filing of public documents with a picture of her house. The lawsuit had the direct opposite effect it intended. Everybody now could see legally, since it was a public document, a picture of her house.) But all that internet gossip aside I'm most impressed by his resume. Here is a quote from the website: Prior t...
