Why are these constructs using pre and post-increment undefined behavior?
...lid but you can't predict the behavior when the code is run.
As far as I know, the standard doesn't explicitly say why the concept of undefined behavior exists. In my mind, it's simply because the language designers wanted there to be some leeway in the semantics, instead of i.e. requiring that all...
Set markers for individual points on a line in Matplotlib
I have used Matplotlib to plot lines on a figure. Now I would now like to set the style, specifically the marker, for individual points on the line. How do I do this?

Exploitable PHP functions
....
Edit: After posting this list I contacted the founder of RIPS and as of now this tools searches PHP code for the use of every function in this list.
Most of these function calls are classified as Sinks. When a tainted variable (like $_REQUEST) is passed to a sink function, then you have a vulner...
What is the difference between #import and #include in Objective-C?
...was already included, as
far as #import is concerned, that file is now already completely included.
Bottom line:
C/C++ headers traditionally includes parts of other include files.
So for C/C++ headers, use #include.
For objc/objc++ headers, use #import.

What is the difference between `sorted(list)` vs `list.sort()`?
...ontent is still the same.
nums
[-3, 1, 4, 5, 7, 8, 9, 14]
nums.sort()
Now the original nums list is changed and looking at nums we see our original list has changed and is now sorted.
nums
[-3, 1, 2, 4, 5, 7, 8, 14]

Behaviour for significant change location API when terminated/suspended?
...
Do you know how long it took for your app to become terminated? And then get a appDelegate callback instead? (Is it like 30 minutes? 2 hrs? 5 hrs? ) The reason I'm asking this is because I've set up a region to monitor. Tried many ti...
PHP cURL vs file_get_contents
... cURL is a powerdrill with a complicated drill chuck that requires you to know it pretty well to actually change it (read: setting cURL options is a bit tedious, but allows for doing anything you want).

Can anyone explain IEnumerable and IEnumerator to me? [closed]
...t's say you are running an airline company. And in each plane you want to know information about the passengers flying in the plane. Basically you want to be able to "traverse" the plane. In other words, you want to be able to start at the front seat, and to then work your way towards the back of th...
Most efficient way to store thousand telephone numbers
...ounts and each count is at most 1000. If we omit the last one (because we know it is 1000 anyway), we can store all of these numbers in a contiguous block of (2^m - 1) * 10 bits. (10 bits is enough for storing a number less than 1024.)
The last k bits of all (reduced) phone numbers are stored conti...
Does Python optimize tail recursion?

The clean way: modifying the Y combinator
The Y combinator is well known; it allows to use lambda functions in a recursive
manner, but it doesn't allow by itself to embed recursive calls in a loop. Lambda
calculus alone can't do such a thing. A slight change in the Y combinator however
can pr...
