  • Design Patters in Rails

    - by Winston
    I remember, I have a GoF book back in college about design patterns which helped me a lot with my C and C++ programming, since my jump ship to Rails I was trying to use those design patterns I learned previously, Rails is a relatively new paradigm to me, plurals, verbs, REST, DRY.. Can you give me a recommended book for Rails that I can easily understand what I previously learned back in College. P.S. I suspect Matz knew about the GoF book, and applied it on Ruby... :-)

  • inserting data into mysql

    - by francesco
    Hi Guys, My insert and update pages (through my admin forlder) into mysql stopped working. When I try to insert/update details it stays on the same page without adding or updating anything into the database table. I really don't know what happened and don't know where start looking. I didn't make any change to the pages whatsoever. Is there anyone who had the same problem and can kindly give me a clue? Appreciated Francesco

  • The speed of Ruby and Java.

    - by Simon
    In every benchmark that I found on the web it seems that Ruby is slow, much slower than Java. The Ruby folks just state that it doesn't matter. Could you give me any example that the speed of Ruby on Rails (and the Ruby itself) really doesn't matter?

  • What does it call in GWT to make 2 UI consistent?

    - by DucDigital
    I saw a video of Google I/O and found an example of GWT UI being very consistent between clients. Which you can save, add, drag and drop in almost real time between clients. I currently don't understand the basic of this (In GWT, i think it implement Comet), so is there anyone can give me a term or definition for this? so I can get it on Google for more information? Thank you very much

  • example of a utf-8 format octet string

    - by erik
    I'm working w/ a function that expects a string formatted as a utf-8 encoded octet string. Can someone give me an example of what a utf-8 encoded octet string would look like? Put another way, if I convert 'foo' to bytes, I get 112, 111, 111. What would these char codes look like as a utf-8 encoded octet string? Would it be "0x70 0x6f 0x6f"? Thanks

  • How do you solve the 15-puzzle with A-Star or Dijkstra's Algorithm?

    - by Sean
    I've read in one of my AI books that popular algorithms (A-Star, Dijkstra) for path-finding in simulation or games is also used to solve the well-known "15-puzzle". Can anyone give me some pointers on how I would reduce the 15-puzzle to a graph of nodes and edges so that I could apply one of these algorithms? If I were to treat each node in the graph as a game state then wouldn't that tree become quite large? Or is that just the way to do it?

  • Why Windows 7 isn't written in C#?

    - by Joan Venge
    I saw a similar question about the reason Google Chrome wasn't written in C#. But with the upcoming version of Windows and Microsoft's flagship language, I am having a hard time understanding why Microsoft isn't pushing C# to its fullest potential to give it more exposure via their market share? In addition can be interpreted as "Is C# and the .Net framework suitable to run a modern OS like Windows 7" Btw this is not a flaming question, but curiosity. I use C# daily and really love it.
