It’s been a bit of time since my last post, but now it’s back to going through Project Euler. The second problem works with a favorite problem in computer science: Fibonacci numbers. Continue reading “Project Euler Problem #2”
I maintain/manage some Websites that are developed by outsiders. Some of them are stuck (for one reason or another) using older tools and software packages … namely Microsoft FrontPage. In one of the websites, in particular, the previous method of showing a larger/zoomed-in version of an image was to open a new tab or browser window using the image’s URL.
After some discussions with the site’s creator and it’s owner, we decided to bring the design up to current practices, and use a modal dialog to display the images. So, I turned to the handy-dandy search engines and, after some searching, settled on ThickBox as the JQuery plugin to use.
Twisted Matrix’s Perspective Broker is, to me at least, the main compelling reason to use the entire framework. It’s also an area that is lacking in documentation that is usable to a newbie to the framework.
One of the things provided by the Perspective Broker is an authentication framework, based around the concept of an avatar. We’re going to create a Perspective Broker authenticator that is more complex than what is presented in the Twisted Matrix documentation.
Another way to integrate Twisted with Stackless python, is to use multiple threads. One thread handles Twisted’s reactor while Stackless tasklets run in at least one other thread. This lowers the deterministic nature of Stackless, but for certain conditions may be more effective than trying to integrate Twisted and Stackless into a single thread. Communication between the threads is handled through a channel, which according to the documentation for Stackless python is thread-safe.
