If you just updated to Xcode 3.2.5 and iOS SDK 4.2, you might find that your existing projects do not compile. This probably doesn't surprise you as it's been the way for every SDK update as far back as the beginning of time (at least in the Jobsian calendar). Thankfully, with Xcode 3.2.5, you can set your base SDK once and for all and it should work for all future releases.

But first things, first, here's the error I received while trying to compile one of the early projects from my iOS SDK workshop: "error: there is no SDK with the name or path 'iphoneos4.1'"

I've been working a lot with Google App Engine in the past few months. I still maintain, as I reiterated recently in my Boagworld interview with Paul, that it's a great idea and has great potential. And the Google App Engine team has been wonderful in working with me and helping me out. Unfortunately, there are a couple of fundamental issues that must be addressed, and addressed properly, before Google App Engine can be taken seriously as a web application platform.

(And no, Java support is most definitely not one of them.)

As I posted last week, a backwards-incompatible API change to the JSON version of Yahoo!'s excellent GeoPlanet API caused the new teaser site for the Singularity web conference to fail.

Today, I got an email from Eddie Babcock from the Y! Geo team informing me that this was due to a regression and that they will be issuing a fix today that will revert the API to its original state.

John Grden just forwarded me an email form John Olsen (thanks guys) alerting me that Apple has reportedly released a fix for the keyboard freezing issue in Leopard.

That's good news but, to tell you the truth, I'm going to wait a couple of months at least before even considering giving Leopard another shot. See, the thing is, I'm really happy on Tiger and downgrading to it made me realize just how many little issues I had with Leopard (responsiveness, general quirkiness, etc.) I absolutely love how stable Tiger is. I love how Tiger looks (yes, I love my non-transparent menu bar, rounded corners and blue apple logo) and I love how everything (all applications, etc.) work. I love the level of polish Tiger has.
