I'm not really surprised. The quark co-processor was disabled in the devkit when it first launched. It took a year or so to get that cleared up and last I looked at the edison quark documentation wasn't great. That kinda killed what differentiated the devkit from yet another linux devboard. 5V IO on the first devkit also seems like an odd choice.

As a linux system-on-module, it doesn't seem badly priced for low quantities/one offs. Although for a little more you can get an arm SOM that has display capabilities.

Actually have one more question if you don't mind - I've done a fair amount of both lisp and embedded (vxworks or baremetal). I've been tempted to push lisp or scheme as a prototyping environment for higher level (i.e., UI or some other non-RT) code. I've always had some amount trepidation due to GC pauses, and memory exhaustion.

Are there any papers on the actual lisp ports? Are there any gotchas?

Thanks for the response!

I appreciate that

The model is really just an abstract compilation of best practices and probably isn't helpful for just line-level developer. Personal Software Process (PSP), with it's pluses and minuses, is a more concrete implementation aimed at a single developer. You could in theory do it within the framework of your company's development process. Overall it's not that dissimilar from Joel's checklist[1] with an emphasis on metrics.

For ATL - you can go in through international terminal and take the tram to the domestic gates. There is just less parking on the international side.

Have you looked at scheme from scratch[1]?

You should be able to do that with either references or pointers between classes with a forward declaration. In essence:

  class B;
  class A { B* b;}
  class B { A* a;}

Not technically a project use-case, but the company or department-wide giant uni-repo is where SVN works well.

Pakistan/India is more akin to North/South Korea. It is impossible for Pakistan or North Korea to maintain dollar for dollar defense spending with their rivals given the size of their economies.

South Africa? Israel?

The GP is talking about the UK.

It may just be the site getting hammered. I'm seeing my searches limited to 2011-Present even though I'm searching 1990-Present.

Same paper - while monoism/simplism/preservatism argument is one of the three major points the full paper. The rest is worth the time to read.

That's a bit generalizing. This paper[1] talks about the over-representation of engineers in violent Islamic organizations. Specifically talks about how there are fewer engineers in Saudi Arabia and Indonesia versus Palestine and other countries in the same type of groups. There seems to be /some/ correlation between economic opportunity and sub-segments of the population joining these types of groups.

Look at the application notes for any LDO 3.3V linear regulator i.e., MCP1702. Or you can power it from a 3.3V USB Serial cable...

This is incorrect for at least python 3.x

I.e.,

  Python 3.4.3 (default, Apr  7 2015, 08:05:21) 
  >>> def mk_generator(initial):
  ...    var = initial
  ...    def increment(count=1):
  ...       nonlocal var
  ...       var += count
  ...       return var
  ...    return increment
  ... 
  >>> a = mk_generator(3)
  >>> b = mk_generator(10)
  >>> a(1)
  4
  >>> b
  <function mk_generator.<locals>.increment at 0x1040a7d08>
  >>> b()
  11
  >>> b()
  12
  >>> a(3) 
  7

Are there other MCUs using the 6502 besides the Western Design Center ones?

I wonder about the economics of that. WDC's 6502 MCUs are 6$ in volume - is he getting a deal or are they soft cores in a PLD?

Both support mmap and shared memory - that's why I found the "shared memory" usenet post a little puzzling.

I think it's less of an issue now than say 10 years ago. VxWorks 6.x added support for protection domains (MPU/MMU support) and RTPs (real time processes). VxWorks 5 everything operated in the kernel. Even with 6.x very little typically runs by default in user space on a VxWorks setup.

With respect to the message passing - both support messaging. VxWorks has several types of message queues - vxworks proprietary msgQLib API, POSIX api etc. QNX has much the same MsgSend/MsgRecv which is the microkernel API and POSIX. QNX has an add-on PubSub middleware that the OP of the usenet group may be thinking of.

It's closely coupled with rule #3. An array at least in the safety critical embedded software have a fixed size determined at initialization. You may have a sentinel value you're looking for, but, the loop should never exceed the preallocated size.

There are another set of arguments /against/ using stopping the loop at the sentinel values because it may make the software less deterministic. But, that's another topic.

That's the transition between the different sources of aircraft power i.e., ground power to the auxiliary power unit.

MTBF generally doesn't imply that the engine is either inoperable or completely failed. MTBCF, MTTF, or other metrics measure that.

The MTBF for a military aircraft as a whole system in general would likely be pretty low since it's composed of so many systems. In essence, something is likely degraded on the aircraft at any given time. That is why there are dual redundancies and easily swappable units.

The Navy is already running a big competition for their carrier based unmanned vehicle (UCLASS)[1]. This competition is part of the reason why, I think, there have been regular press releases coming out from Boeing, Northop, et al. and the Navy regarding drone capabilities - carrier landings, mid-air refueling, etc.

There is a r7rs scheme (kawa) that runs interpreted on the jvm and can compile down to class files.
