Review: The Lutron MS-OPS2 occupancy sensor switch

Dave Farquhar Saving money February 19, 2012September 10, 20171950s, 1960s, CFL, curtains, incandescent bulbs, led bulbs, occupancy sensor, thermal curtains

I installed a Lutron occupancy sensor switch this weekend. It detects you entering the room, turns the lights on, then turns them off five minutes after it detects nobody is in the room. The timeout period is adjustable. It comes in four models: MS-OPS2-WH (white), -AL (almond), -LA (light almond), and -IV (ivory) and retails for $29.

Installation was surprisingly easy–it took about 15 minutes, which is about how long it takes me to change a regular switch, and unlike most models in its price range it works with modern CFL and LED lighting, but I recommend some prep work ahead of time. Read more

SCO v. IBM winds toward resolution

Slashdot reported yesterday that SCO v. IBM is back on. Well, it is, sort of. The case never was fully resolved, due to SCO running out of money and filing for bankruptcy. Groklaw has the details.

If this sounds vaguely familiar, I’ll try to refresh your memory.

I’ll miss you, Gary Carter

Dave Farquhar Baseball February 17, 20121980s, baseball cards, christmas, Cuban Nationals, National League, New York

I was really sorry to see that Gary Carter lost his battle with cancer this week. He never played for my team and was never my favorite player but I can’t think of a player who exemplified baseball in the 1980s and everything that was right with it more than he did.

In the 1980s, he picked up the torch from Johnny Bench to become the best catcher in the National League. At the beginning of the decade, he was a perennial All-Star. He won a World Series in dramatic fashion in 1986, while playing for the hated New York Mets. By the end of the decade, he was a part-time player. But he never quit smiling, and he played the game in a way fitting of his nickname, “The Kid.” He kept on playing, even if only as a part-timer, until his body wouldn’t let him do it anymore. The same way we played baseball in the back yard.

LED lighting gets cheaper

I saw this week on Cnet that Pharox is selling basic, bare-bones LEDs direct from its web site, hoping to get consumers to try out LED bulbs.

The Pharox 300 is a 6 watt, 360 lumen bulb priced at $6.95.

The Pharox 200 is a 5 watt, 240 lumen bulb priced at $4.95.

SSD future isn’t bleak, just flash

Dave Farquhar Hardware February 17, 2012computerworld, hp, kingston

Computerworld is predicting that the end of the line for SSDs will be the year 2024.

That’s based on the projected year MLC flash memory becomes impractical to continue producing. There’s one problem with that assumption: it assumes SSDs will still be based on flash memory in 2024.

HP has a brilliant idea

After last year’s flip-flopping on getting rid of its not-quite-as-profitable-as-they’d-like PC business, and the resulting self sabotage, HP needed a good idea to try to undo the damage.

Their idea is completely unoriginal, but it’s tried and true and more likely to work than anything else they could possibly do: Bundle their premium PCs with premium-level customer service and charge a little more.

Fixing track that gets hot at the track joints

I saw a question about a Fastrack layout getting hot at a track joint. That’s a conductivity issue causing voltage drop, which in turn causes the heat. While not likely to be dangerous, it’s a sign of inefficiency and can lead to other problems, such as the train slowing down at some parts of the layout. Poor conductivity also causes motors to run hotter than they should, which can eventually damage the armature.

I can think of two fixes, none of them especially expensive or time-consuming. And although this question was about Lionel Fastrack, it can happen with other makes of track too, and even other scales.

New Order, Joy Division, surviving and moving on

Dave Farquhar Music February 15, 2012March 6, 20251990s, computer security

I couldn’t tell you the last time I thought about Joy Division, and then one of my college classmates posted a story about a stash of Joy Division and early New Order master tapes showing up in the basement of a former bank, along with guns and gold (but presumably, no butter). Yes, the jokes write themselves.

Instead of talking about the contents of the tapes, the story talked about New Order going on tour. I was vaguely aware that Peter Hook quit the band, and another story on the site discussed that: New Order is back together without Peter Hook, and Peter Hook is planning on touring as himself and playing Joy Division songs. And he’s writing a book about his time in Joy Division.

As a guy who spent way too much time listening to Joy Division in college, and who for a time ran the largest Joy Division tribute site on the Web, yeah, I have some opinions on all that.

How to clean heat sink compound off a CPU

Cleaning heat sink grease off a processor is something I hope you don’t have to do often. But if you find yourself needing to remove a processor from a motherboard, it’s a good idea to clean off whatever compound is on the surface of the chip and apply a fresh batch.

You can do it with household tools.

Upgrade update

My new fire-breathing dragon of a server is sitting idle at the moment. I would have liked to have had it up and running today, but now I’m starting to realize why it took me so long to migrate off my Pentium II-450. Setting up Linux web servers is a lot more complicated than it was in 2001.

They can do a lot more than they could in 2001 too, but when I first built that server, the process literally went in about three steps: Install Debian, apt-get install apache mysql php, then download blogging software, create a MySQL database and account for it, edit a config file, then start blogging. You could get it done in an hour, and a lot of that time was waiting for stuff to load off a CD-ROM or download over a 256K DSL connection.
