Gill found these instructions for making plasma in a microwave by carefully cutting up a grape and then nuking it. I finally got around to trying it yesterday, and it’s awesome. Even better than microwaving a light bulb in a glass of water. Check it out:
Neutrino by Frank Close
Narrow topic, but an interesting book, especially the frustratingly long effort to reconcile observed electron neutrinos from the Sun with reality. Has a rather repetitive recap at the end that ends up recapping some of the recap which rather bogged things down. I definitely know more about neutrinos than I did before though.
Mark Jackson, my co-founder at Cucku, is blogging re-mastered debugging tips from StackHash. StackHash is now an open source project and all of the great content from the original site has been taken offline. This new project is a great resource for debugging on the Windows platform, especially post-mortem crash dump analysis. If that’s your thing do yourself a favor and subscribe to Mark’s blog.
Slightly easier than Half Dome, and when you get to the top you get to look at Half Dome. What more could you ask for!

Black Diamond Mines Regional Preserve is an East Bay park spanning more than five thousand acres.
I spotted what looked like an easy four mile loop. It was nearly seven, I guess all the .3’s really do add up. The loop we did was a mix of exposed sunny ridgelines and shady canyons. We went on a ‘cold’ day which was still high 80s and a nice sweltering break from the San Francisco fog.

Wasted far too long on trying to get WCF to work with custom basic authentication this week. Custom in the sense that I need to look up the username and password in a database and not have IIS attempt to match the credentials to a Windows account. Given how well WCF 4.0 supports RESTful services in general it’s a bit shocking that basic auth over SSL isn’t supported out of the box. It seems like you should be able to derive and hook up a class from UserNamePasswordValidator, set the transport clientCredentialType to Basic and be ready to go. I’ve heard that this works for self-hosted services, but no dice in IIS.
Basic access authentication is a simple protocol and so in the end I added a helper method that checks for access (and in my case returns the user information for later use) at the start of each call into the service. It’s very simple:
- Check WebOperationContext.Current.IncomingRequest.Headers for an ‘Authorization’ header. If it’s there decode and validate the credentials.
- If the header is missing or the credentials are incorrect add the WWW-Authenticate header to the response - WebOperationContext.Current.OutgoingResponse.Headers.Add("WWW-Authenticate: Basic realm=\"myrealm\""); – and then throw a WebFaultException with a 401 Unauthorized status code.
This triggers a browser to prompt for your username and password and then try the request again. When calling the service in code you can add the ‘Authorization’ header preemptively and skip the 401 response entirely.
RESTful .NET by Jon Flanders
Great coverage of exposing and consuming a RESTful service using WCF. Note that you'll need the services of a good WCF book, this builds on existing WCF expertise and doesn't try that hard to bring you up to speed. Which isn't a bad thing, it keeps the book relatively short and focused. I'll be referring back to this one often.
Rule 34 by Charles Stross
Stross flips out concepts in a sentence that many SciFi authors would build an entire book around. It's a near-future police procedural set in Edinburgh. Twisted, tongue-in-cheek, profane and most excellent. The only miss is the assumption that people will use Wave in the near-future, let alone now. It's the first book of his that I've read... will be seeking out more soon.
The Information: A History, A Theory, A Flood by James Gleick
Epic. A must read for cybernauts who may have forgotten their roots. Good for anyone else interested in what information actually is, and how pervasive information theory has become.
