Raphael now has drag and drop

I know this is old news.

It's been a while since I worked on the stageplan app. One issue I worked on a lot was how to drag items around (not to hard) and rotate them (a bit harder), and then how to drag them around in a rotated state.

I have lately discovered Raphael's drag-and drop functionality which didn't exist in previous versions. It has now allowed me to position a "hot spot" on objects, which when dragged around can be used to calculate the angle of rotation of an object.

Calculating that angle took a bit of trigonometry and then getting "resetting" the object to a new rotated state before the next click-and-drag was harder still.

Add a bit of code for grouping the main object with its hot spot, and it works!

Very cool. (At some point, I'll put up a demo here.)

No rules

It's rather sad to observe the descent of 9rules since the buyout by Splashpress Media.

I mean, Christian Montoya has apparently given up being a designer and is now a DJ, and no one at 9rules has noticed.

Who is Rebecca Black

No one will accuse me of not being hip to what the kids are listening to these days, because even I know the meme last weekend was Friday.

Now, a lot of people are giving young Rebecca an awful serve. Perhaps it's because even she, as a privileged white American 13-year-old, should have realised the song is totally shit and refused to participate until they—the exploiters who served it up to her—gave her something mediocre.

Still, as others have said, she seems sweet enough. I figured that, despite the Autotune hell, she couldn't be that bad... she got the lead in her high school's production of Oklahoma. A show like that is not an easy sing.

Well, it turns out that, for a song with a melody requiring a vocal range less than an octave, the use of Autotune was completely justified.

Win a mic with Recordinghacks

Recordinghacks has a contest with the major prize a Lewitt LCT-640.

The Lewitts haven't made it to Australia yet, and may never, but the review makes them sound pretty good. And who ever looked a gift horse in the mic?

Potter's not perfect

Over the past few months, I've been reading my son Harry Potter. That's a little surprising to some who know he's only six years old. My partner and I have considered it carefully as there are some very dark themes (for example, Cedric Diggory's death at the end of The Goblet of Fire). But, so far, he's loving it, understanding much more than I thought, and retains an amazing memory of events in the earlier books.

A child who likes Harry Potter....not much of a revelation, is it? I've been quite dismissive of J.K. Rowling's creations in the past. Some years ago, courtesy of Daniel's cousins, I read the first three books. Well, I gave up part way through the third book. They seemed to be the same and included a few unnecessary subplots. (Norbert the Dragon in the first book comes to mind.)

However, I'm now forced to re-read those books and for the first time read more. And there are some things I find quite grating.

But one thing I do like, which I hadn't noticed before, is that Harry has faults. He behaves as one might expect a child to behave. He puts up with an awful lot (like years of child abuse at the hands of the Dursleys). He gets angry when we think he's not entitled to. He holds grudges. He makes bad decisions... and some good ones too.

I can appreciate these books much more now.
