I knew there was something bugging me about Chrome, but I just couldn’t put my finger on it. I finally realized what it is: There’s no menu bar!

I suspect someone’s going to give me an Amazon gift certificate for Christmas, and someone already gave me an Android. What’s the best book for learning to develop or Android? There aren’t a lot of choices yet:

• Professional Android Application Development (Wrox Programmer to Programmer) by Reto Meier (Paperback – Nov 24, 2008) $44.99
• The Busy Coder’s Guide to Android Development by Mark L. Murphy (Paperback – Jun 25, 2008) $30.00
• Android A Programmers Guide by Jerome DiMarzio (Paperback – Jul 30, 2008) $39.99
• Hello, Android: Introducing Google’s Mobile Development Platform by Ed Burnette (Paperback – Dec 28, 2008) $32.95 $21.75
• Android Essentials (Firstpress) by Chris Haseman (Paperback – Sep 18, 2008)

Which ones are worth the paper they’re printed on and which ones are headed for the recycling bin as soon as the next SDK version hits the ether?

I’ve been compiling ghc from MacPorts on this 2.0 GHz MacBook, and I’m beginning to wonder if it’s hung. I’ve been stuck on “Building ghc” for quite a while, maybe an hour:

--->  Cleaning perl5.8
--->  Fetching ghc
--->  Attempting to fetch ghc-6.10.1-src.tar.bz2 from http://haskell.org/ghc/dist/stable/dist/
--->  Attempting to fetch ghc-6.10.1-src-extralibs.tar.bz2 from http://haskell.org/ghc/dist/stable/dist/
--->  Attempting to fetch ghc-6.8.2-darwin-i386-leopard-bootstrap.tar.bz2 from http://haskell.org/ghc/dist/6.8.2/
--->  Verifying checksum(s) for ghc
--->  Extracting ghc
--->  Applying patches to ghc
--->  Configuring ghc
--->  Building ghc

Certainly it was long enough to answer a bunch of e-mails, and edit an article. Is this the point where it actually compiles the compiler? Is ghc self-hosting? That is, is ghc written in ghc? That may be what the bootstrap bit is about. Yep, looks like it is.

I do remember 2 hour gcc compiles, but that was 15 years ago on much slower hardware. How long does it take to compile a compiler nowadays?

What’s special about the number 8.388608E06F? The answer will be in my next developerWorks article.

Read on for a hint.

I’ve upgraded this site to WordPress 2.7. Please holler if you notice any problems.

Ning has proven why you can’t trust your web site (or web application to the cloud). Just listen to Ning’s Gina Bianchini:

We’re not discontinuing the Red Light District because we no longer believe in the freedom to create your own social network for anything as long as it’s legal. We do. Practically though, supporting adult networks no longer makes sense. Here is what we’ve seen in practice to date with respect to adult social networks on Ning:

Adult social networks don’t pull their own weight. Specifically, they require other social networks to work harder because they don’t generate enough advertising or premium service revenue to cover their costs. Plus, our ad partners aren’t big fans of the adult networks and therefore require us to identify adult networks or risk our healthy advertising revenue. We don’t want to be in the policing business and, unchecked, that’s where this is heading.

In other words, Ning just decided to cut off people who’d built sites on top of their platforms, because, hey, they felt like it. The pornography just wasn’t as profitable as they expected.

This isn’t the first time this has happened either. FaceBook and Apple have also shut down useful and popular applications because they just didn’t like them. The only safe and sensible course for anyone running a web site/web application/blog is:
