A quick “back of the envelope” calculation

Sunday, October 22nd, 2006

A standard U.S. letter envelope measures 9 1/2 by 4 1/8 inches. Assuming a 1/8th inch margin, that’s about 35.8 square inches available for your project-saving calculation (the one that points out that the heat death of the universe will occur before that 17-way-join query you just wrote completes when faced with real customer data).

By contrast, a 4×6 index card provides 21.5 square inches of usable space, assuming the same margin.

The envelope provides ~66% more usable space than the index card.

Now you know.

And now back to the work I’m avoiding by telling you this.

YOUR SPEED IS

Sunday, October 22nd, 2006

Over the past few weeks, radar signs have been popping up along my commute route. The type with a fixed sign for the speed limit, and a lighted YOUR SPEED IS display that’s tied to a radar gun.

“Cool,” I thought, “I’ll check my speedometer.” Approaching a sign, I’d get as close to 30 MPH as traffic allowed in a 35 MPH zone. A sign near home consistently reports 28, but one closer to work claims 34-36. So, not so accurate.

Yesterday I’m behind an SUV, with Porshe on the right. The radar sign ahead is flipping madly between 9, 18, 14, and 11 MPH. It can’t get a lock on any one of us. This problem is complicated by the fact that all three cars are idling, fully stopped, at a red light. Perhaps the sign is confused by the radar-reflecting stealth coating on the Porshe, and is reporting instead on low-flying geese.

The Gremlins of Dawn

Thursday, October 19th, 2006

No morning is truly complete unless you can spend part of it on your back under a desk, trying to reach a USB cable so that you can unplug it long enough for an attached device to reset. Bonus points if, while under the desk on your back, you notice fresh blood on the side of a computer, but can’t see how or where you got cut. Thoughts like “I shouldn’t be trying this without caffiene” or “Wow, it’s a mess down here” may attempt to distract you. Ignore these thoughts. They are traps set by the Gremlins of Dawn to divert your attention from the power strip switch that they’ve stealthily maneuvered into a perilous position.

A restructuring interlude, with rubber mallet

Saturday, October 7th, 2006

My home office is a disaster that’s been getting worse. The mess on the desk has been getting in the way of my getting stuff done, in part by keeping too many distractions within sight, and in part by being a hazard. Piles get knocked over, and I have to stop what I’m doing to pick them up.

It’s not been the greatest place to get work done.

The upstream issue is surface space. When we moved, I gained a few square feet of floor, but lost a lot of shelf space. The stuff that was on those shelves is still around, mostly in boxes or piles that migrate from place to place.

In a rare lucid moment the other day, I noticed that the 4-drawer file cabinet in the corner would fit into a space in the closet, freeing up just enough room for a bookshelf. I don’t open the file cabinet that often, and it would be the same distance from my desk if it moved.

Today, armed with a tape measure, I drove to the local Danish furniture store, found a tall bookshelf (some assembly required) that would fit the space (and would fit in the car with the back seat down), emptied the file cabinet and moved it into the closet, assembled the bookshelf, and filled it with books. And restocked the file cabinet. And dusted a bit.

Elapsed time: 3 hours, including coffee break.

That’s three hours I won’t have to apply to the large stack of work that I need to get done. But I suspect the time taken will pay for itself, and my wife is happy to see those boxes of books finally go away.
