Piece of my Heart

I still can’t believe what I just heard. On 540 AM, CBC just played, back-to-back, Janis Joplin doing Piece of my Heart, followed by… Faith Hill “doing” it. It was awful. Hill completely missed the point of the song, “countrifying” the tune and really doing a consistent job of making Joplin’s signature blues tune into a horrible, flat episode of listening pain that simply didn’t work.

It wasn’t even funny. Just awful.

Ah, the radio habit… is there anything you won’t eventually hear?

Python, TkInter, OSX (OS X) and making it all behave

I use Python a lot. Python 2.5.1 to be specific. And inside Python is TkInter, which, with a little work, will give you a handy way to put a GUI together. But there are problems. To say that TkInter is poorly supported and poorly documented under OSX is to understate the case rather dramatically. So you’re left to Google for answers, and mostly, they aren’t to be found — or if they are, they aren’t obvious or easily found. So I’m going to provide some answers here that have taken me quite some time to collect, and hopefully keyword and title them so that a Google search will actually get you to the solution you need sooner rather than as much later as it did me!

Review: Canon EF 100mm f/2.8 Macro Lens

100mm Generally speaking, the Canon EF 100mmis a great lens. The bokeh is fine. The lens is pretty fast. f/2.8 to f/22 is useful as a creative range. The optics are sharp and the all-time focusing is a boon. So what’s not to like? Well, here’s the thing. The Canon EOS50D, which I use, has the ability to use the viewfinder in “live preview” mode, and when doing so, will allow you to zoom in on your focus point (or anywhere else, but that’s irrelevant to my point here) such that you can see extremely fine detail. At which point you can manually focus the lens so that it is exactly right. Marvelous, right?

It would be. But the lens has some mechanical backlash problems. Let me explain backlash; if you’re not familiar with it, it takes a bit of describing.

Review: Monster MP PRO 3500

mp3500
My A/V system has a fair amount of stuff. There’s what I call the current generation set of gear… There’s a Sony STR-DA5300ES receiver, a separate 750 watt power amp for my sub, a PS3/Blueray, an XBox360/HD-DVD, a conventional progressive scan DVD player, a Wii, a DBS/DVR, a Mac Mini and a CD/MD player. Then there is what I call the last generation set of gear, an XBox, a PS2, and a Gamecube. There are several wall warts for things like rechargeable Wii controllers, an XBox 360 wheel, a network switch, a power supply for the dish multiplexer and so on. All of this feeds an Optoma 1080p projector which has its own UPS that also runs the Mac Mini (you really don’t want a projector to suddenly lose power… the fan stops and the bulb immediately overheats, losing lifespan or even dying right there on the spot; and of course you don’t want power to a computer failing, ever.)

The wiring for all this stuff is… formidable. Prior to getting the Monster unit, there were multiple power strips and cables just everywhere. So the first thing I got out of the MP PRO 3500was increased organization and lessened clutter. I still needed a couple of power strips, partially because wall warts take up so much room, and partially because there are just so many units, but trust me, it is a lot better than it was.

New Tee Shirts

Some of you may have noticed the tee shirts available at the top right of the page; these are original designs by yours truly. Purchasing them supports the site, and as a special bonus, you are almost certain to really offend someone if they look closely enough at the design. Please take a look; I struggled over these designs in my vector editing software, Intaglio, for, oh, at least a few minutes. Each!
