I would guess it declares a pointer-to-bool called foo, and then initializes the pointed-to bool as false. Is that not what it does?

Luigi Thirty posted:and problem #3 was that my cheap Chinese breadboard had a continuity problem causing strange behavior I feel your pain Luigi. When I was doing undergraduate research I spent literal months trying to figure out why the electronics I had designed weren't working. My adviser was at CERN the whole time and he wasn't really much help via skype/email/etc. When he got back he took one look at things and said, "Your breadboard has too much inductance; this would work fine on a PCB. Also because you wasted an entire summer you can't do a senior thesis with me."

Ralith posted:If you're using gcc >= 4.8 or clang and targeting x86, "-fsanitize=address" is handy for reliably detecting this kind of mistake. I've gotten to the point of reflexively checking it every time something breaks in a confusing way. "-fsanitize=undefined" is pretty neat too. Be warned that enabling either of these on a codebase for the first time can be pretty scary. sadly, cortex-m4 is a baremetal arm target. but you're right, i should really be stubbing out my HAL and compiling locally for unit tests/ubsan/all that poo poo, i just haven't gotten around to it yet.

caveat: breadboards are good if you want to test something quickly at a really low frequency, sub 1MHz. if you have a nice new breadboard you should have no problems. the problems come when your breadboard is a few years old, or new and bad, and doesn't make electrical connections like it used to. if you have a scope and are willing to git bitten by your board once in a while, then it is a good tool. like any tool you just need to know of its weaknesses.

i'm biased against breadboards bc for me its easier to ask a technician to prototype something for me. when the techs are busy, or if its something really simple i'll breadboard it.

i had this undergrad analog electronics course where the professor had a filing cabinet with all the project solution breadboards neatly knolled out on the cabinet shelves. wires all perfectly straight, except at the bends, which were perfect -- perfect length. component legs trimmed, flush against the board. breadboards can be good.

Ugh anybody have a good reference for me to learn how to C++(11?) on microcontrollers without burning the house down? I write C most of the time and C++ is weird to me as-is, but I want to be an hero and do it on a micro with interrupt handlers, no heap memory, minimal library support and all that other good stuff. Specifically Cortex-M0.

Specifically Cortex-M0. don't know that you'll actually find a reference that goes into this targeted at embedded development you'd probably do better to read lots of general stuff about C++11/14/17 and the theory behind it, maybe there will be a bunch of stuff about leveraging it for games development in blog posts or on gamasutra or something that will translate then I'd say start experimenting on a non-bare-metal system that's still pretty similar to your target, but which has enough horsepower to compile, debug, and so on. (like a RPi2, since you're targeting ARM Cortex-M0 eventually.) you can try to write code on that which avoids allocation, callouts to anything other than runtime functions you supply, that compiles small enough for your needs, and so on. once you get the hang of it you can use a bigger machine since you're going to be cross-compiling for the Cortex-M0 anyway, but something like a RPi or RPi2 could still make a useful target since unlike your real computer it's ARM and it might let you test some things more accurately but still with faster turnaround than some bare metal. also, I suggested clang rather than GCC because you may wind up wanting to customize your toolchain, runtime, etc. and it'll be much easier that way. plus clang is a good compiler all around.

Specifically Cortex-M0. it'll be fine, i do this a lot. two things 1. you may need to define stubs for certain syscalls 2. if you don't want to use the heap you basically can't use any of the stl containers, so you're basically going to be writing strongly-typed c, just be aware

backend web dev isn't much better, in my experience (which is absolutely biased because i don't live in a great tech city). still doesn't pay great, still prone to everyone fawning over the framework of the month, it's boring (how many different ways do you really need to parse json?), and if you're especially unlucky you'll end up maintaining spaghetti php.

the application I work with started life as coldfusion, was turned into asp.net, and is now being converted to Java/GWT. I'm assuming when Google deprecates gwt it will go back to asp.net.
