  • Ruby 1.8.7 and RSPEC tutorial

    - by Ben Nelson
    I'm just diving into ruby development for a class assignment and the machines at my Uni have only got ruby 1.8.7 on them so I need to develop for that. I have found tutorials on the web for ruby = 1.9 and rspec that are really good but I haven't found anything for ruby 1.8.7 (I'm guessing it's pretty dated?). Does anyone have anything using rspec testing and has an indepth discussion on ruby 1.8.7 for me? I'd really appreciate it! Thanks!

  • Url rewriting : prevent to display xml

    - by Frank
    Edit : I've got an aspx file (default.aspx) that loads a flash file (index.swf), but this swf needs a xml file (foo.xml) to load correctly. However, I would like to block any request aiming directly at the xml file. Is it possible, using a rewritting engine (isapi_rewrite for example) to detect if the xml file is being 'hotlinked' or being loaded by the 'index.swf'(inside default.aspx)? Any ideas? Thank you.

  • MySQL - What is the correct primary key method

    - by Hammerstein
    I'm starting to develop an application using MySQL and although I've developed apps before using databases, I've normally gone to the incrementing id method. The other day I was reading a posting somewhere and saw someone being picked apart for this, for not properly "normalising the database". I'm not a big database person, but I wanted to make sure I'm doing this right. Any ideas, help / guidance?

  • File uploading with ColdFusion, too big of file timing out?

    - by knawlejj
    A client has the admin ability to upload a PDF to their respective directory and have it listed on their website. All of this works dandy until a PDF reaches a certain file size that makes the server time out. This causes an error and the file uploaded will not succeed. As mentioned in the title, we are using ColdFusion with a command. Is there any java/jquery/flash modules or applications that could resolve this issue?

  • Rotating blocks in JavaScript.

    - by Alvin SMith
    I'd like to create a JavaScript web app that makes blocks appear on the page that can be dragged around by the user. If I used DIVs with background colors, it would be easy to rotate them by 90 degrees at a time. However, if I wanted to rotate them arbitrarily, how could I accomplish this? I'd rather not have to resort to Flash, images, or HTML5.

  • Adding folder to Eclipse classpath

    - by Paul
    Hello, When i develop a project i create a folder in my project called libs. And in this folder i place all the library jars that i use. Is there a way to add just the libs folder to the class path so that i do not have to add each individual jar? I was thinking something along the lines of a variable or creating a user library. Many thanks.
