I wrote lots of C on Vaxes back then.  It wasn't that much different
than writing C today.  Compiling was much slower per KLOC but you tended
to work on smaller programs.  Interactive debuggers (then and now) let
you trace through a running program without having to recompile it a lot
of times.  Forth's much faster compilation lets you insert tracing and
recompile instead of using an external breakpoint debugger, we've had
some threads here comparing the approaches.  It didn't occur to me
til just now, maybe C users preferred debuggers because they avoid
recompiles that are much cheaper in Forth.

Overall though, I think the big productivity gain over the VAX era is
that C is now relegated to a low level systems niche, with application
programming usually done in HLL's.

Whether that's useful depends of course on what you're trying to do.

Hmm, most of those chips let you erase and rewrite flash blocks under
program control.  So I was expecting an Arduino-like system where
there's a protected bootloader in low flash, that lets you load your
program over the same port that's used for other comms.  You don't need
to mess with an actual flash programmer unless you somehow corrupt the
boot loader, which is hard to do by accident.

> Why bother with the ARM server?  Why not just use your PC?

1) the ARM server is an actual server, in a data center, running 24/7
   with high speed internet, etc.  I can access it from anywhere and
   serve data to other computers from it.  I can back it up over the
   network without being limited by my slow DSL uplink.  I don't have to
   worry about bogging my laptop down if I run an overnight computation
   on it (I did a 7 hour software build a couple nights ago), etc.  I
   always prefer remote servers to my laptop for big calculations, since
   the laptop fan turns on and the thing feels like it's straining.

2) I wanted a 32-bit system to mess with and my laptop has a 64 bit OS.

3) The ARM is a crash and burn machine.  If I mess something up badly
   enough, it's no big deal to wipe it out and reinstall.

4) I'd like to try ARM-specific software like Mecrisp, which has an
   ARM Linux port.

5) The ARM servers are crazy cheap (0.6 eurocents/hour or 3 euro/month
   rental) and I can acquire and release them under program control
   through an API.  They're about 1/4 the CPU speed of my laptop, or
   similar to a netbook Atom or a RPi model 2.  So for 60 eurocents an
   hour I can launch 100 of them in parallel and do a calculation in a
   few days that would take months on my laptop.  There's actually a
   shortage of the boards right now (probably can't get 100 at once) but
   being able to do that is the design intention and hopefully they'll
   get more hardware in place soon.  It's sort of a miniature EC2 cloud.

A tethered Forth may be even better-- Elizabeth says her users prefer
that to resident Forths these days.  I don't know of any free ones
though.

Hmm ok.

> I'm not looking for chip docs, I want board docs.

I thought Olimex published a lot of such stuff.  You could ask on their
forum.

> MUCH easier.  Heck, using a STM32F4 means it may already have a port.
> I may have to try this one!

There's a link in the Hackaday thread to Seeed Studios which sells them
for $8.  Let me know if you get one and do anything with it.
