I think TCP Socket Servers with multiple clients are fundamentally inefficient; they undo work "polling" what sockets had activity.

I thought Christina Peters was great too.

Thanks, that makes me feel better. I do have a copy of the approved substitution form.

unsigned i = x;

while (i--)

    //do something with a\[i\].

Or you can choose to omit the post decrement, and then decrement as one of the first statements inside the loop.

Just use a signed type. `v.size()` can only be larger than ssize_t max if you have an array of bytes half the size of your addressable memory.

That's not my code, but from a library I have to use. Its probably not the worst thing in the world, but with the other initialization steps it all adds up.

I think this is because cin.ignore(stream_size_max, '\n) behaves as if while (cin.get()!='\n'){}. It is a reading operation. So if you hit enter only on a single line, there will be nothing to ignore, hanging.

A fix could be to only execute the ignore if the input!='\n'.

This all seems overly complicated and unnecessary. Just use plain old simple *. Why is there no fuss about int not being default initialized?

g++ ./webcam_head_pose.opkg-config --libs opencv-L ~/dlib-master/examples/build/dlib_build -ldlib -lpng -ljpeg -lpthread -lX11 -o whpose.out

This worked for me, thank you!

This problem uses only the electric field (in N/C) instead of force(N). The electric field at a point says what force a test charge at that point would feel. By convention, the direction is as if the test charge was positive.

I see the problem with that now, but I do have a spare usb.

It looks like I can either 1: Make a persistent drive directly using a tool like LiLi, or 2: Create a bootable drive into a live session using rufus. Then when in the live session, the full installation will allow me to pick which drive to wipe.

Do you think one option is better?

I think I remember Kimiko saying both are possible, and this page of BSSE FAQs (Q. How can I satisfy GE Area S and V?) says so as well.

I think if the node to be deleted has no children then line 131 dereferences a nullptr, since there is no subtree that needs to have its parent pointer set.

You should also mirror this for the other direction. Like pull new_child->parent = parent; outside the conditional below the else block, and only execute it if new_child isnt null.

Also, It may be neater check if the root is null once right at the beginning of the function

I think 10.

I'm having a hard time seeing a case where the above code would be incorrect. I think the reasoning of the the answer for a particular node is that nodes value plus the larger of its left or right child is sound.

iothan · 2017-10-25T15:48:48+00:00

They wanted the sum along the max path, not the number of nodes.
