If Merb is a paragon of professionalism and class, Shoes is a monkey on LSD. Shoes, by why the lucky stiff, is an incredibly compact cross-platform GUI toolkit for Ruby, but it looks nothing like the other cross-platform toolkits out there. For one thing, it is lightweight. Shoes lets you build GUIs in Ruby whose code actually looks like Ruby, not XML or Java. We are going to build a pastebin as a repository for our own code snippets and pieces of text we want to save. We'll build a GUI frontend using Shoes, and connect it to a Merb backend that will handle the database. In fact, the basic proof of concept took the two of us about an hour to get working, and it took another hour to finish. Without further ado, we present our pastebin application, using Shoes and Merb, Shmerboes. Creating a Simple YAML-Based Web Service with Merb
February 17th, 2008 A 'problem' with the Mongrel/Rails platform A request comes in to the web server, and if it's dynamic, falls down to a waiting mongrel process. Mongrel calls Rails which wraps a big lock around most of the request/response cycle so the mongrel thats serving the request has to wait for a response from Rails to unlock and start serving other requests. This is the Blocked Thread stability anti-pattern that Michael Nygard talks about in Release It!. The problem is that Nginx or Apache doesn't know that a mongrel is blocked and keeps blindly sending requests. Thats means that even a single blocked mongrel will result in some slow responses for requests that come in to that same mongrel. Cut the Request Fat And one way to do that is to use the "Skinny Request, Fat Backend" principle. What that means in practical terms is pretty simple: Do as little as possible inside of the Request/Response cycle.
* MakeCloud simplifies adding a cloud to any web page. Give it an RSS feed, and it makes a link cloud that summarizes the contents of the feed, and provides code to embded the cloud * FeedMarklet instantly creates an RSS feed and a browser button. You click the browser button to add whatever page you are currently reading to the feed. It is faster and easier to save links, because you do not have to interupt your browsing flow to go to a different website, and it automatically extracts information to save you the effort of entering it manually. * Video Lecture Database is a collection of links to streaming video lectures on subjects ranging from quantum mechanics to literature. The lectures are tagged. * The WizzardWiki is a power user's wiki- no stripped down markup here, just raw HTML, with real-time previews. * Hebbalicious is an experimental link cloud. Links get bigger when clicked, and anyone can submit a link. The cloud sorts out the rest.
