Vacation Crunch

jliu83 — Wed, 28 Jul 2010 12:19:36 +0000

Sorry guys for the lack of update. I’m currently working on a SPI section for the PIC24 controllers. I’m going on vacation for a bit so I’m trying to finish up a bunch of stuff at work. Might be a while before a new section is published.

In other news, Linux has been working out great (using it as a home server), although I still can’t develop jack on the platform.

New Article on Coding

The rivers are drying up pretty quickly in this summer weather, so no kayaking for a while. I’ve made a commitment to try to increase my output on this website (which currently is quite pitiful). Despite the World Cup being constantly played on ESPN3, I have managed to finish writing an article on on blocking code. Head over there now to check it out.

The embedded underworld

кухненски столовеThere is a unseen war going on, that is mostly unnoticed by the majority of the masses. The desktop/laptop consumer market is quite sizable, but the real money is the embedded market. Most reports seem to indicate that the embedded market is about 10 times the size of the consumer computer market. You can wage the Mac OS vs Win7 vs Linux debate all you want, but the debate can’t hold a candle to the massive battle of the embedded OS.

And it’s easy to see why. Think about how many electronic device you have in your house. Compare that with the number of computers. You might own 3 or even 4 computers, but I’ll bet you a nickel that you have at least 10 times that many embedded devices in your house. Your washer/drier, microwave, router, even surge protectors these days have some microcontroller(s) running the device. Not every one of them is running Windows Embedded or Linux Embedded or FreeRTOS, but if you’ve seen the functionality of some appliances these days (internet refrigerator anyone?) there’s bound to be an OS underneath.

I was getting my car serviced today and the smug guy next to me had a macbook pro. I asked him if he liked his macbook pro, and he gave me a slew of one liners about how the os/computer is faster/better/badass than a PC. Not that I’m against macs or anything, but I feel like a lot of people miss the point. There needs to be a bigger awareness of the technology around us. The embedded world is so massive, but it is unfortunate that not many people understand and experience it.

Next time you look at a fancy surge protector, just think about the lonely programmer in India that probably had to write the C code for the device. I promise that you’ll get a new perspective of the world around you.

Dead Cow was Awesome

The east coast storms have settled and the Potomac is raging! Just check out the gauge below at Little Falls.

It was 8 ft yesterday and Dead Cow came in. Here’s a photo of a friend from a while back. Gonna ask my friend if he took any photos yesterday.

Happy Paddling
