Solving the Shakespeare Million Monkeys Problem in Real-time with Parallelism and SignalR

Editor — Sat, 12 Nov 2011 01:09:22 +0000

A little over 18 months ago I was talking to Stephen Toub (he of the Parallel Computing fame ) about parallelism and the kinds of problems it could solve. I said, naively, "could we solve the million monkey's problem ?" He said, "the what?" "You know, if you have an infinite number of monkeys and an infinite number of keyboards they will eventually write Shakespeare ." We brainstormed some ideas (since Stephen is a smarter than I, this consisted mostly of him gazing thoughtfully into the air while I sat on my hands) and eventually settled on an genetic algorithm. We would breed thousands of generations of (hypothetical) monkeys a second and then choose which ones would be allowed to perpetuate the species based…(read more)

Travis Leithead showed a video "Building responsive apps and sites with HTML5 web workers" in BUILD.

Asynchronous scalable web applications with real-time persistent long-running connections with SignalR

Editor — Mon, 29 Aug 2011 09:29:37 +0000

I've been spending some time exploring asynchrony and scale recently. You may have seen my post about my explorations with node.js and iisnode running node on Windows . Every application has different requirements such that rules to "make it scale" don't work for every kind of application. Scaling a web app that gets some data and for loops over it is different from an app that calls out to a high-latency mainframe is different from an app that needs to maintain a persistent connection to the server. The old adage "when all you have it is a hammer everything looks like a nail" really holds true in the programming and web space. The more tools – and the knowledge to use them – the better. That's why I'm an…(read more)

Learning about Progressive Enhancement – Supporting Mobile Browsers with CSS3 Media Queries

Editor — Thu, 25 Aug 2011 08:03:39 +0000

I blogged about how happy I've been working with designer Jeremy Kratz on my recent site redesign . We've been meeting lately about small improvements and tweaks. One of the core goals was to support many screen sizes from 30" down to a small smart phone screen. You can see the results on the right in a Windows Phone and iPhone. My team is doing a lot of work on Mobile lately, not just with things like jQuery Mobile and what that means not just for ASP.NET but the mobile web in general. We've also worked with 51Degrees and they've even created a NuGet package that can help you tailor your site to any device. You'll hear more about Mobile in ASP.NET from Steve soon and I'll be sharing some ideas in a few upcoming…(read more)
