How to Embed Linux
·
· Score: 3, Insightful
There are many other options far better suited to the problem domain
Which problem domain ?
It seems you are assuming that every possible embedded situation requires real time scheduling from the OS.
I use the Linux kernel for many embedded devices where I work, but I have not REQUIRED real time scheduling yet for any of them. DVD Player, Parking Machine, Firewall Appliance, Router, etc... None of those need real time scheduling.
There is no need to put a server OS in a defibrillator
This achive of Issue # 8 seems to be unclear as to what happened when they started being hosted by Linux Journal.
And finally, I want to offer a very special note of thanks to Phil Hughes at the Linux Journal. Phil is one of those infectiously nice guys that starts a casual conversation with you and after 2 hours, you're talking and laughing like life-long buddies. He's a great guy and I'm absolutely delighted that he and the folks at the Linux Journal have been willing to take over the care and feeding of the Linux Gazette.
That seems to support lg.net's position - Just a hosting arangement.
But..
So, after chatting at some length with Phil Hughes about this, I've decided to turn the Linux Gazette over to the Linux Journal. I think that the Gazette has demonstrated the "proof of concept" -- that a freely available and open-to-all online publication is a great means for sharing information and ideas. There are a number of great things that could be done with this and I'm excited about the Gazette continuing on in this tradition.
That seems to show that Fisk is turning it over to SCC. If that is the case then this is SCC's baby now.
You can see in the write up where each side is getting their views
Net result, this could have all been handled with a little more tact on both sides. If SCC had just followed the wishes of the people who produced the article, this wouldn't have been a problem.
It should have been the creators of the work, the volunteers, who should have been deciding on what direction the magazine should take. Not some marketroid who found way to suck $$, or techie who felt this was his site, and wanted to put up a CMS and/or excert his power.
I from what I read of #8, I would have to say SCC has the stronger argument, even if they have the,IMHO, worse site - I want a online mag, not a CMS.
Though two sources of free online linux articles is better then one.
..for their work, the copyright has been properly handled, and now you own a proper copy of any Canadian artist's song you download off the internet.
Put that onto a Canadian CDR disc, and now you have compensated the Artist twice, so now I have an extra copy that I can give away to someone on over the internet.. But wait, if they download it, they are compensating the artist too - Another legal copy.. We will be swamped with legal copies!! The Horor !
$50 a year buffet style vs $0.99 a song..:)
(Though I don't know if I am going to find 50 good Canadian songs to download)

In an infinite universe it is highly probable that exactly what you need grows naturally somewhere.

Is it really that crazy of an idea to try and bring some structure ?
It would be nice to know be able to know that these 73 files belong to this program, and those 86 belong to this other one WITHOUT having to rely on a package management system
Yes, it is, and that is why I used it as a point for my example.
It is to bad that some developers are staying away from linux because of this scare over the GPL. (like the post a few down under the parent thread)
As long as you pay attention to the license of the software you use, (Which you should do no matter WHAT software you use) Linux can be just as good (or IMHO Better) than any WinCE fully closed source solution.
As an added bonus, I get to use some of my teams resources to help improve the underlying base GPL/ LGPL software with bug fixes and additions to it.

GPL and Leased Software?

1) Take router - i386 tiny board.
2) Put on Linux kernel + Busy Box + uClibc
3) Put on closed source, linked against uClibc application that contains in itself no GPL Code.
Question:
Does source for that closed source application have to, in any way, be provided under the terms of the GPL ?
As far as I understood it, the ONLY things that would HAVE to be provided would be a CD with the Linux Kernel, Busy Box, and uClibC, should someone ask for it.
(plus any changes you made to the above source)
Is this wrong thinking ?
It seems like a lot of people out there are handing out lots of FUD that is preventing developers from using a perfectly good platform for their embedded systems.
Or am I the one spreading the FUD, and in fact, in the above senario the closed source software would have to be given out, destroying the posibility of Embedded Linux from every being used in any commercial product using generic hardware
