I only very rarely need 240V, if I had permanently mounted 240V machines or frequent needs, I would do exactly what you propose.

two poles breakers, 2×120V@20A, $USD: - $20 - GFCI, $115 - GFCI + AFCI, $115 Yes it is expensive, but it can also save your life.

I am aware of this. But then I have a single 120@20 vs a single 240@20. With my setup I have 2×120@20 always available, and 240@20 for the occasional welding. I could assign a different 120 phase to every other outlet but then I would need

You can feed a US outlet the split phase 240V and get two 120V@20A each. It used to be done in kitchens in the US, back when appliances were power hungry. I have done so in my workshop for the same reason. Houses are wired in split phase 24

Redirecting the gutter downspouts away from the house can help if this isn't already done. EDIT: saw your other comment about drainage being an issue in the yard, not the house.

Maybe if alloca is used with a runtime value uncapped, a user could then trigger a stack overflow with too big of an allocation. This is the same problem when allocating on the heap, with the difference that the heap is a few order of magni

My answer would be: No they are not the same type. Yes they have the same amount of bits representing them. They might have different RAM usage because of alignment.

With a huge static stack allocation the stack check must be done within a parent function instead of within the same function. In any case it is up to you to do the stack check. Though alloca can easily be wrapped by a function running the

Your example behaves the same with or without alloca. It will run until it runs out of stack. Or it might just run forever because the compiler optimized it as an infinite loop. In any case, same behavior.
282.
by bombela 2y ago
Stack allocation is always done at runtime. Baring special optimizations, the CPU and the code work together to (stack grows downward) decrement the CPU stack pointer register. This register keeps track of where the bottom of the stack is.

The stack grab is as permanent as any other stack variable. There is nothing special about it. The only difference is that you can decide at runtime how much to add to the current stack frame.

> How much memory is used for the stack and when it is freed can always be determined at compile-time. Technically, not always. You can allocate on the stack at runtime, see "alloca" in C. But is alloca even that useful in prac

Uninsulated attic: do you mean the attic is not part of the conditioned space? Or that there is no insulation at all? Because attics don't appear to be insulated in the bay area. There is usually insulation for the ceiling below though

The UX is garbage. It tracks my phone's motion, making it incredibly jittery (I guess I don't have the rock steady hands required?). And one finger starts an automatic zoom, while two fingers unzoom.

For many small one off projects, you don't need enough ancillary components to require a dedicated PCB. Merely soldering a few pins to some buttons, LEDs, perhaps a ready made relay module etc. In this case, a perf board to hold everyt

I managed 1μm/minute when electroplating PCBs at home. Faster and it grows a sponge of copper (entrapped gas I assume). I would like to know how they did it.
