Deleting lines from one file which are in another file
...print }' exclude-these.txt from-this.txt
The output will be in the same order as the "from-this.txt" file. The tolower() function makes it case-insensitive, if you need that.
The algorithmic complexity will probably be O(n) (exclude-these.txt size) + O(n) (from-this.txt size)

How to optimize for-comprehensions and loops in Scala?
... loops, Scala's for comprehensions are actually syntactic sugar for higher-order methods; in this case, you're calling the foreach method on a Range object. Scala's for is very general, but sometimes leads to painful performance.

...t will.
innerHTML returns the HTML as its name indicates. Quite often, in order to retrieve or write text within an element, people use innerHTML. textContent should be used instead. Because the text is not parsed as HTML, it's likely to have better performance. Moreover, this avoids an XSS attack ...
How do I capture the output into a variable from an external process in PowerShell?
... you capture the output, it is properly interleaved, using the same output order you would get without 2>&1; in other words: when outputting to the console, the captured output does NOT reflect the order in which stdout and stderr lines were generated by the external command.
If you capture ...
JavaScript curry: what are the practical applications?

Another solution would be to use a std::set, which guarantees the ordering of the elements and provides a method iterator find(T key) that returns an iterator to the given item. However, your requirements might not be compatible with the use of a set (for example if you need to store the sa...
