Reality check: Where is embedded Linux?

Found via Slashdot, the New York Times published a story about how mobile operators are complaining of too many mobile phone operating systems, and the hard work of supporting them all. One of the interesting statistics in the story was provided by Canalys, a London-based market research firm. If I can believe the numbers, here's how OS use on smart phones stacks up:
  1. Symbian, at 66.7%
  2. Microsoft, at 14%
  3. Research in Motion, at 7%
  4. Linux, at 6%
This only adds up to 94% of the market, which makes me wonder how the rest of the market (6%) is divided up. Whatever.

I say it's interesting because of these numbers supplied in early 2006 by The Diffusion Group:
  1. Symbian, at 51%
  2. Linux, at 23% (double its 2004 share of 11.3%)
  3. Microsoft, at 17%
It may be that the TDG report is for all mobile phones, not just smart phones. Again, whatever.

Returning to the first article I find it interesting how some of the major players want to divvy up their supported operating systems. Vodafone wants to concentrate on just Microsoft, Symbian, and Linux. DoCoMo wants to concentrate on Symbian and Linux. That's all very well, but there are 2.5 Billion handsets out there, with over 1 Billion having been manufactured in 2006 alone. That number is a combination of handset replacement in the market along with new growth of 10% to 15% per year. The average life of any model is about 18 months. With a very large customer base and this type of turnover real innovation occurs at a much faster rate than it does in the PC market, especially in the operating system arena. This dynamic growing market is partially the result of a lesson learned from the PC market; never let any one vendor, OS or otherwise, dominate. They don't trust Microsoft. They'll work to make sure that choice remains.

If the operators want both choice and a way to deploy the same content across all platforms, then why not use Java Mobile? It seems that the majority of the mobile phones run some ARM variant, and those ARM-based chips support Java at the hardware level. They can write to one language and deploy to every platform that supports it. That's the promise of Java's WORA (Write Once Run Anywhere). If may be that not all implementations of J2ME are equal, and if that's the case, then you're right back to supporting only those platforms whose implementation meets a minimum capability. If that's the case, then that's a excellent example of the market at work. If you can't meet a market demand, then you suffer and your competitors, who can, advance. Success based on true technical merit, not strong-armed marketing tactics. Not like Microsoft in the PC OS market.

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

first night for the gingersnaps

The first night has passed and the two have managed to survive, in spite of what their tiny hearts might have thought when first arriving. Greebo, the larger of the two, has been in hiding the entire time so far. Ponder has spent the time zipping in and out of hiding spots, checking things out, and learning just how comfortable pillows are for resting your head.

During the night I felt the tiny body of Ponder hitting the bed as he leaped up on the side, and then climbed to the top to run around on top of me. At least once he play-attacked my fingers. He might be small but his claws are still quite sharp.

When I got up in the morning the bowl of cat kitten food was fairly well depleted. It's been refilled and fresh water put in the big dish on the floor. I'm assuming that both Greebo and Ponder are feeding and drinking. I have seen Greebo under the furniture peeking out at me when I went looking for him. I'm leaving him alone while he continues to adjust.

So far the guys h…

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…
