Living in a Linux Embedded World

It's still interesting reading though for some insight into a different world for Linux and there is a nice reference in the comments to the interview of Victor Yodaiken of RTLinux fame by by Kevin Fu on the ACM site."
It's a pretty strange coincidence. Today I had to get information about a company for Professional Communications class. I went to the library, picked up an IT trade magazine, and went to the section about emerging companies in the new year. There is apparently a company called Kada Systems. That has created an extremely small JVM that can run very powerful applications on very small portable devices. Take that and your tiny linux kernel, and you're set.
The GeekNights podcast is going strong. Listen!
The people who need the hand-holding which Lineo, etc. are trying to sell, those people are too conservative to choose Linux, they just go with the Microsoft of the embedded word, Wind River.
Like so many things in the computer world, there is a need for education in the Real-Time embedded arena. When I was at the Embedded Systems Conference - Boston 2001, Red Hat's CTO gave a presentation on Embedded Linux, and touted RTLinux as the up and coming 'official' Real Time approach. In a later discussion with him, we agreed what everyone seems be missing here
Most embedded systems are *NOT* hard real time systems. For those that are, there it the RTLinux wrapper that runs Linux as one of it's (lower priority) processes. Yet the people writing for sites like this have no clue and spread FUD, which the unfortunate reader often mistakes as factual.
Will Embedded Linux ever be popular? It all depends on if the Embedded Systems Engineers ever get properly educated as to what it can do, and how. The only real drawback is footprint size. If you need your embedded application to be small and run on 8-bit Microcontrollers, then Embedded Linux clearly isn't for you. However, for the vast majority of serious applications, Moore's law continues to make Embedded Linux a more and more viable solution if the Engineers start addressing the learning curve. Of course, first, they have to know that such an effort is worthwhile. With FUD like this article spreads, it will unfortunately be longer until people get it. No big surprise here. Almost everyhting worth while gets early adopters, goes on hiatus, and then comes back as the new latest and greatest thing that everyone always new was going to fly. You gotta love the cycles of life!

Why didn't your company want to release the kernel mods back to the community? It's not like they were gonna make any money off them - they get paid for the embedded app, not the OS it runs on. I could understand if you were giving away something proprietary, but it doesn't seem to me that releasing those changes would have hurt your company one little bit. In fact, if you had released them, someone else might have come along and improved on your improvements.
Admit nothing, deny everything and make counter-accusations.
I'm a junior engineer at a small company producing (a fairly killer, IMO) embedded-linux (ix86 atm, but that could change next release) device. Although the RT side of things is not my schtick -- I'm writing some custom web software and working on our in-house embedded-linux distro --- I *do* know that our RT guy is the biggest linux fanatic I know. He seems to have no problems using the RT stuff that's freely available for the linux kernel, and kernel-versus-license-wise, we're simply going to release the stuff we need to keep proprietary (FPGA drivers and firmware-adjustment/config stuff) as kernel module(s).
:)
In fact, RT guy *regularly* slams anything that doesn't have adequate RT support, so I am left to assume that he deems to have a set of RT capabilities which is more than adequate.
We're a small company, and running (like everyone else) under some rather tight fiscal constraints.
AFAIK, linux is what is currently saving our collective bacon -- if we're going to compete with the economies of scale of the big boys (not to mention their 'Deep Pocket Error Correction Algorithm') we can't afford to license some proprietary OS or development environment and pass that cost on to our customers. We have to be clever; therefore, we use Linux.
(Aside: I wish I could provide more details, but really, I'm more of a CS geek. My ideal level of abstraction is somewhere just south of lisp and north of Java. Assembly makes me go *bew*bew*bew*bew* (imgine index finger oscillating in front of lip). )
