   I worked on some safety critical systems in C. The philosophy was treat the code like a little person running around. The person (the code) always wanted to know where the fire escape was. The fire escape always needed to be very easy to us

   While address space is huge, RAM isn't infinite. Our embedded Linux runs out of memory quite often. Or if the swap space fills up on a server with a disk. I've spent many hours chasing corrupted memory due to someone not checking

   What sort of C programmer wouldn't test for malloc() failing. Drives me batty to see articles where malloc() is happily assumed to always succeed.

   "None of Idaho’s most-searched dishes are built around its most famous crop, the potato. We choose to assume that Idahoans know their potato preparation techniques and don’t need online refreshers." Damn right we do. :-)

   Why not ROT13? Or a simple substitution cypher? Not trying to be silly. But if the only goal is to prevent man-in-the-middle attacks such as someone mangling the data, why not "corrupt" the data such that the phone company in the

   The Arduino embedded C library (which I'm assuming they're using) isn't as rich as a Glibc or uclibc. Sometimes I have to fall back on very old school methods to build complex strings.

    How do you define "user computer"? We run a bazillion tests on our stuff during manufacturing. Stuff is plugged in/out of Windows boxes over and over on the manufacturing line. It's hard to tell where that "last st

    I work on printers. We've done useful things with our USB to make them appear as mass storage (drivers stored on the printer--no download necessary). Once the driver installed, we switch over to a printer+scanner profile. If we can pre

    Tricky part is finding a bug in the firmware after release. If locked out, then can't update the stuff in the warehouses. Would need to scrap all parts in inventory, potentially costing hundreds if not thousands of dollars.

    Why not something like a USB Firewall? Black/white list vid/pid (which are easily faked, yes). Closes the door a small amount. But can also blacklist all HID.

    Embedded firmware engineers are so conservative I bet the firmware for tricorders will be written in C.

    While I dislike #if/#else/#endif, dynamic libraries rarely exist in embedded systems. Using many small object files is my solution of choice but it pushes the if/else/endif problem into the Makefile instead.

    Thanks for the runbox.com mention. That looks like just what I need for my server.

    Yeah, tools from hardware vendors are notoriously awful. Embedded debuggers (JTAG) are almost always terrible, too.

    I see a potential market for a mechanical device that automatically covers up the license plate when the car is parked & turned off. Pull into parking space in the mall. Cover up your license plate. Or, better yet, put an image of rando
