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!

Wordpress migration… not quite perfect

Although the process of moving the blog was generally successful, the posts no longer reflect the number of comments made on them – although the comments are actually there. So if you want to see if anyone has commented upon a particular post, you’ll have to click on the post and scroll to the bottom. I apologize for the inconvenience, but I don’t know how to go about fixing this at this point in time.

One more little bit of weirdness is that I am now “admin” instead of “fyngyrz.” I probably just need to make another account or sign in differently. This isn’t too serious an issue.

Other than that, looks like everything made it ok. Please let me know if you find anything severely out of whack.

Technology Predictions

I often read the predictions of futurists with interest; it is always enjoyable for me to consider what they have to say, why I might agree or disagree, and mentally file them away for later validation – or not.

Today, I’m going to venture a few predictions of my own, based on the state of affairs that exists in early March, 2009. The idea is to re-visit them in the years to come and see how many, if any, were close to how things actually develop.

Pixels Per Planet

In a fit of doing something that will be useful to almost no one, anywhere, I have created a calculator page that will tell you how many pixels a solar system planet, or an object of your own choosing, will consume in your final DSLR image.

In order to figure this out, you tell the calculator just a little bit about your camera, your lens system, and optionally, an object of particular interest to you.

If you actually use this thing, let me know in the comments. I suspect that I may, just possibly, get one comment. From me.

Here’s the calculator page.

…and of course, if you find any bugs, let me know.

Man fights federal "sex offender" list registration

Here’s the story.

Both the feds and the states are prohibited from creating ex post facto law.

Adding to someone’s punishment post-conviction is explicitly ex post facto.

This is why Ohio reasons that this particular person should not have to register. They understand the constitution, and their registration law is constructed to obey it.

However, the supreme court has ruled that registration is “not punishment” (which is sophist, ridiculous and absurd, but regardless, that’s what they said.)

Consequently, any state or the feds can register anyone, for anything, pre- or post-conviction, guilty or not. Another example of just this kind of misuse of power is the no-fly list. They make the list, decide you belong on it, bingo, you’re on it, and you have no recourse.

Today's EBay – or, how to ruin a fabulous cash cow.

Back in the day, when EBay first poked its head above the waters of the web, it offered the following high-value combination of features:

  • A reputation system; buyers rated sellers, sellers rated buyers. Caveat Emptor was possible!
  • An inexpensive display venue; it was worth a try to sell something.
  • Open communications; communications enhance confidence.
  • Numerous payment methods; flexibility made buying and selling alike easy.
  • Easy record keeping; just save the web page as a file.
  • Support: Just ask, and a person would give you an answer after a day or so.
  • Quality search; keyword based and easily controllable, search and ye shall find.
  • Deep search; you could see what items like yours had sold for for many months back.
  • Transparency; you could see who was bidding, their reputation, etc.
  • Low fees; it was worth seeing what you might like to sell. Bargains were everywhere.
  • Garage sale writ large: If you owned it, you could sell it.

Flash forward to 2009:
