Tux Enlisted for U.S. Defense Program
An anonymous reader writes "Linux is a key part of the Army's massive $200B FCS (Future Computing System) initiative, it seems. RTOS vendor LynuxWorks was chosen to provide the OS for 18 weapons platforms under development, because its LynxOS-178 real-time OS can run Linux binaries -- including the "common operating environment" that Boeing is developing for FCS."
...this paper talks about using the open source, BSD-licensed agent framework COUGAAR to run FCS modeling tests.
Also, there's a bunch of COUGAAR support software written in Ruby, i.e., ACME.

It will be. Then in comes SCO and takes the credit
Scully: Should we arrest David Copperfield?
Mulder: Yes we should, but not for this.
Nothing says "feel-good bluegrass tech movement" like becoming part of the military industrial complex.

That is all.
Colonel Panic: Not just a reaction to incorrect artillery coordinates anymore!
Do you like German cars?
Apparently not. The press release states that they provide ABI compatiblity using special shared libraries ("[...] compatibility is implemented through the use of dynamically linked shared libraries[...]", similar to WINE). Maybe they have ported GNU libc to LynxOS and use some free software. But apparently, no Linux kernel code is involved.
You're shooting for the Funny mod, but think about it.
- The precursor to the web we're both using right now was pentagon (ARPA) funded.

Since Linux isn't actually involved in this project in any way, shouldn't the summary state that GNU is a key part of the FCS initiative?
Tux is actually sitting this one out.
Under the GPL I don't think they'd have to submit anything back unless they distributed it publically anyway.
Linux Wireless Hardware in the UK
No more so than cars, truck, aluminum, steel, or coffee is. All of which is used by the military around the world, for good or evil.
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
No, it's a real-time OS that can run Linux binaries. Linux isn't really a real-time OS, although there's been a lot of hackery recently to change this.
LynxOS is older than Linux. Development on LynxOS began in Dallas, TX in early 1986. The system was built for the 68000 architecture originally, targetting a custom-built 68010 VME bus CPU. The software was compiled with the C compiler sold by Megamax for the Macintosh. LynxOS was ported to the IA86 for the 386 in 1988-1989. The LynxOS ABI compatibility history goes back to about 1989 also, when SVR3 compatibility was added to the system. No UNIX or (of course) Linux code was used in the development of the OS.
Well, BSODs are pretty much a thing of the past, at least unless you have a defective hardware.
That said, when Windows is used where formerly an embedded OS is used, there is a tendency not to do a very good job stripping out all the stuff that's not needed. Since you aren't going to be patching things that much in the field, this could lead to known security holes on deployed systems for a long time. It may not matter, indeed usually the excuse is that it won't matter, but sometimes the unforseen happens. It's not unheard of for "embedded" versions of windows to have problems like windows file sharing turned on. The hardware engineers don't think like sysadmins.
This problem is not intrinsic to Windows; I've seen the same thing recently on a box that controlled an under vehicle scanner. It used stock SUSE with an old verison of BIND and samba, trhe3 works. The customer wanted to connect it via wireless to a central guard station. This was a bad idea. The security holes in the box are harmless as long as it is stand alone, but on a network they are huge liabilities.
At least with Linux, you can go the Linux from scratch route, which minimizes you exposure to security holes in ancient software.

Crappy application not fully tested (and they knew that and accepted the risks) didn't know how to handle an improper user input. A zero went into the database. The app couldn't handle the DIV0, and crashed.
The Navy report concluded it was the application and human error, and not NT.
LynxOS is not Linux. It's a completely different, and much smaller, kernel. It's not as minimal as QNX; LynxOS has drivers in the kernel. But it's far smaller than Linux. It's small enough to get through the expensive and difficult examination process required for avionics.
Confusingly, the company that sells LynxOS recently changed their name to LynuxWorks, and also distributes BlueCat Linux, an embedded Linux distro based on the 2.6 Linux kernel. LynuxWorks had a huge booth at the Embedded Systems Conference last month.
LynxOS, BlueCat Linux, and QNX all use the GNU compilers and tools. All are POSIX compatible, and will run most commmand line programs with a recompile.
Hi all,

Lynxworks can say whatever they want, but the Army isn't picking an OS until 2006. See this link: http://www.fcw.com/fcw/articles/2005/0214/web-fcs
Here is one quote that may be interesting:
"Cartwright and Muilenberg downplayed rumors that they decided not to use Microsoft's Windows operating system in FCS because of security issues. The officials said they have made no such decision to date."
In a letter to the "Comment and Discussion" department, published in the Aug 98 _Naval_Institute_Proceedings_, page 22, Captain Richard T. Rushton, then-CO of _Yorktown_, categorically states, "The _Yorktown_ was never towed as a result of any Smart Ship initiative. During my command, we lost propulsion power twice while using the new technology. Each time, we knew what caused the interrupt and were underway again in about 30 minutes. The September 1997 incident was caused by incorrect data insertion by a well-trained crewman. The _Yorktown_ returned to port using two FFG-7 emergency control units that specifically had been requested by me, and supported by other commands as a risk reducer. We knew there were some risks in the engineering development model propulsion-control system installed under a rapid prototyping development effort. The bottom line: The data field safeguards found in production-level systems were not installed yet in the _Yorktown_ by intention, until complete wring-out was accomplished."
Further: ... She went on to execute a five-month Caribbean deployment that included extensive Smart Ship assessments by the Operational Test and Evaluation Force and Navy Manpower Analysis Center. Both organizations evaluated the _Yorktown_ as fully capable in meeting the required operational capabilities in a projected operating environment. ..."
"The _Yorktown_ never missed an operational commitment, nor did she suffer a mission-degrading casualty during the Smart Ship assessment period. During that time she certified to deploy under the normal fleet training and assessment process.
You fit a missile with a Linux kernel. Does this mean that every time you distribute the software by nuking someone you have to drop a copy of the source code in the crater afterwards :)?
Hmmmmmm..... Deep fried and look like Squirrel.
