Filtering a list based on a list of booleans
...olution) create np.array from both lists, use boolean indexing and finally converting array back to list with tolist() method. To be precise, you should include those objects creation into time comparison. Then, using itertools.compress will be still the fastest solution.

What is the equivalent of the C# 'var' keyword in Java?
...possible in Java (all Types had names, even if they were extremely verbose and unweildy). I do not know if this has changed in the mean time.
var is not the same as dynamic. variables are still 100% statically typed. This will not compile:
var myString = "foo";
myString = 3;
var is also useful whe...
Using msbuild to execute a File System Publish Profile
... Copy element is a bit complex;
it performs a transform of the items and converts their paths to new
paths rooted at the PublishDestination folder (check out Well-Known
Item Metadata to see what those %()s mean).
To call this target from the command-line we can now simply perform

Writing a compiler in its own language
...ve to parse strings, specifically escape sequences. You will write code to convert \n to the character with the decimal code 10 (and \r to 13, etc).
After that compiler is ready, you will start to reimplement it in C. This process is called "bootstrapping".
The string parsing code will become:

What are some better ways to avoid the do-while(0); hack in C++?
...le useful, is not a silver bullet. When you find yourself about to write a convert-goto-to-RAII class that has no other use, I definitely think you'd be better served just using the "goto-end-of-the-world" idiom people mentioned already.

How to get a specific output iterating a hash in Ruby?
...
Calling sort on a hash converts it into nested arrays and then sorts them by key, so all you need is this:
puts h.sort.map {|k,v| ["#{k}----"] + v}
And if you don't actually need the "----" part, it can be just:
puts h.sort

What is the difference between C, C99, ANSI C and GNU C?
I have started programming practice on codechef and have been confused by the difference between C and C99. What does C mean here? Is it C89? Check the languages at the bottom of this submit . It contains both C and C99.

Why is SCTP not much used/known
...e IP network, in contrast, is open and not reliable, and telecoms will not convert to it if it won't handle at least the load that SS7 handles. This is why SCTP was developed. It tries:

Saving images in Python at a very high quality
