Internet service has no maverick

If you’re like me, you have exactly two places from which to buy high-speed internet service: your phone company (mine is Verizon) or your cable TV provider (mine is Time Warner Cable).

That sounds like competition, doesn’t it? If you don’t like one, you can go to the other.

Why would I switch?

After nine years (and about $10,000) […]

Home theater upgrade, part 2, fixing HDMI

(Part one found here.)

First I’ll mention that the AV preamp I started out with, a Marantz 7005 purchased as B-stock from Outlaw Audio, turned out to be hopeless. It would never successfully handshake video output to either of my displays, even with no sources connected. Sometimes on a hard reboot, it would send some video, then […]

Home theater upgrade story (Part 1)

Old system:

Rotel RSX-1065 receiver
Panasonic TH-50P9UK plasma display
Old Pioneer DVD player
InFocus ScreenPlay 5700 projector
Roku
B&W CDM7NT 5.1 system, with broken tweeters on the front mains
Logitech Harmony One universal remote

Why upgrade?

The Rotel receiver has annoyed me for years with its few seconds of silence after mode switches (like Dolby Digital to PCM during a TV broadcast). It’s volume behavior […]

April Observing: Supernova and a Comet

The weather forecast for our favorite spot, Amboy Crater, called for decent conditions but high winds. (Why do we care about the wind? Here are four reasons I can think of: simple comfort, blowing charts and equipment, maintaining a target in a telescope, and blowing dust.)

The best forecast in the area was at our old favorite […]

Finally some observing weather

See Jane’s observing report from the same evening — some great binocular observing with Kemble’s Cascade.

The 20D mounted piggyback on the Traveler and Mach One GTO mount, hoping to catch comet PANSTARRS on its first opportunity.

Several months ago, David Green of the Santa Clarita Valley Photographers Association invited me to give a talk on astrophotography […]

“Why didn’t you just …”

Here’s one post that’s equally valid for bridge and computer programming.

Have you ever accomplished some task and had someone say “Why didn’t you just” do it some other way? Usually their suggestion is assumed to be the obvious or simpler way to do something.

In bridge, maybe you misplayed the hand, or chose a different lead on […]

Ruby gem problems around libv8, therubyracer, mac vs. linux, native extensions

I haven’t done a techie blog post for a while, and this “solved problem” keeps raising its head at work, so here goes.

Here’s the situation:

A ruby web app
Develop on Mac OS X
Deploy on Linux
Using bundler to control gem versions
Using therubyracer and libv8

You build your app on your Mac, install your bundle of gems using bundler, and […]

Kaiser Low Calorie Diet, Terrible Execution

Like so many of us, I need to lose weight. My doctor at Kaiser referred me to a new in-house weight loss program, a low-calorie “meal replacement” program. The program appears to be a franchisee of Robard Corporation’s “New Direction” program.

The program itself is very good. The class materials are current and instructive, and the high-protein […]

Hot, dry astronomy

My piggy back shot of Scorpius taken in the early evening. Note the Pipe Nebula near the center left, a dark dusty pipe in silhouette against the Milky Way. Click for the full-resolution image.

Observing report for June 16, 2012, Amboy, CA

The forecast for Amboy had a high temperature of 104°F and a low of 72°F. […]

Galaxy season

Jane snapped Mojo waiting for darkness at the Amboy Crater visitor area.

Observing report, April 21, 2012, Amboy, CA

We’ve had a string of bad luck with new moon weekends for the past six months, so when this new moon Saturday showed nearly perfect conditions, Jane and I were quick to pack the van and get out […]
