Google launches Google Apps Premier Edition

As rumored yesterday , Google made a major announcement : a subscription package of premium, hosted business applications. (Man, Arrington's sources are scary good). The service combines GMail, Google Calendar, Google Talk and Google Docs & Spreadsheets for $50 per user annually. I still insist that...

An Introduction to OpenID

OpenID, which describes itself as "an open, decentralized, free framework for user-centric digital identity", has been gaining momentum and getting press in the Identity 2.0 space. The fundamental idea of OpenID is that a URI is necessarily unique and thus a good way to identify users. If you say you...

If you can read a file, you can copy it

Raymond reminds us that there is no "Copy" access mask because copying is not a fundamental file operation . Copying a file is just reading it into memory and then writing it out. Once the bytes come off the disk, the file system has no control any more over what the user does with them. Something to...

JSON and XML

Back at the PDC, I mentioned that Microsoft chose JSON over XML in Atlas, its AJAX framework. The debate has reared its head again recently, prompted largely by Tim Bray's post . Tim says that JSON is great for its single intended purpose, "to put structs on the wire." Dare, who used to work on the XML...

The Prevalence and Danger of SQL Injection

Michael Sutton looks at the prevalence of SQL injection vulnerabilities ( via Bruce Schneier ). He tested 708 different servers and found verbose SQL errors on 80 of them (11.3%) - numbers that are not, as Michael says, surprising but are certainly sobering. Michael acknowledges that his method is imperfect...

Intro to Cryptography Course

A University of Washington course in Cryptography is available online , including videos of all the lectures ( via Bruce Schneier ). I've listened to the first lecture and it seems like a great introduction if you're interested in the subject. Interestingly, he cautions about Schneier's "popular-but...

The Illustrated Guide to Cryptographic Hashes

Another one of those things that's been lying around for awhile. This is a pretty good introduction to cryptographic hashes - what they are and what they aren't, why they are useful, how they work and how they fail. It's a useful, slightly more accessible resource I tend to send around whenever these...

Fiddler 1.0

Something I meant to mention awhile back: Fiddler , my favorite HTTP debugger that I've mentioned in the past , released version 1.0 over the summer. (It's now up to 1.0.1). Fiddler has always been one of the better tools for doing HTTP inspection - I personally think it's faster and easier to use than...

PDC05 - An Introduction to MSBuild

Faisal Mohamood, a good friend, former colleague and more recently PM on the MS Build team, gave a great lunch session on the new MS Build System. It was originally scheduled for Day 1, but moved because the keynote ran so long. MS Build is the new build engine that ships with VS.NET 2005. It is based...

What do you think about LINQ?

Leon points out some LINQ love . Well, the article may be great, but I'm a bit more torn on the technology itself. The computer scientist part of me finds this very cool from an implementation perspective. The combination of anonymous types, lambda expressions, method extensions and a bit of compiler...
