The contractor was out today doing some painting and checks, and briefly activated the solar power system. It was generating about 5000 watts, most of which was flowing back out of my house into the power grid. No air conditioning or TV was on, so besides my computer, refrigerator and some lights, we weren’t using […]

Looks like there’s going to be a “Day 4” post. They didn’t finish today. I guess the rain Friday and Monday set them back a little. Most of the work today was wiring, in and out of the attic. Not much to show, but I’ll post some pictures anyway. Here you see where the wires […]

Two things were accomplished today: They cut the tiles so the mounts could extend up through them, and they fastened rails to the mounts. Here are the rails. Tomorrow they should fasten the solar panels to the rails. Looks like the ends still need to be trimmed. Here is a close up of one mount […]

Hybrid Hot Water Heater Followup
October 12th, 2011 · 2 Comments
I posted in February about installing a new hybrid hot water heater. Although the initial price was almost $1000 higher, it is supposed to cost less to operate. 6 months later, I have some data. Comparing kilowatt-hours consumed in 2011 with 2010, my average monthly bill is $43 less than it would have been at […]

The sender used something called “Right to Left Override”. It was originally implemented to support languages such as Arabic that write right to left. If […]

Tablet Buying Frenzy
August 21st, 2011 · 15 Comments
HP announced a couple of days ago that they were going to discontinue their “TouchPad” tablet. They decided to clear inventory by reducing the price to $100 for the 16GB, or $150 for the 32GB version. The web and retail stores immediately were hit by a buying frenzy that is still going on. Most of […]

Going Solar
July 13th, 2011 · 7 Comments
About once a year I check the price of adding solar photo-voltaics on my roof, and every year decide that it’s still too expensive, and the payback is too far out. This year things finally look good enough, with payback estimated to be about 10 years. Tax credits and utility company rebates cut the cost […]

Pale Moon
May 5th, 2011 · 4 Comments
***Geek interest only disclaimer.*** Lately I’ve been using the Pale Moon web browser. It’s a modification of Firefox, optimized for speed and simplicity. (I was going to call it a “fork”, but since each time they update Firefox they soon create a new Pale Moon based on it, it’s not really a true fork) It […]
