What is the difference between varchar and varchar2 in Oracle?
...language types instead of proprietary data formats. OCI can perform a wide range of data type conversions when transferring data between an Oracle database and an OCI application. There are more OCI external data types than Oracle internal data types.

%s specifies all lines. Specifying the range as % means do substitution in the entire file. Syntax for all occurrences substitution is :%s/old-text/new-text/g
g specifies all occurrences in the line. With the g flag , you can make the whole line to be substituted...
Splitting a string into chunks of a certain size

return Enumerable.Range(0, str.Length / chunkSize)

Please note that additional code might be required to gracefully handle edge cases (null or empty input string, chunkSize ...
List comprehension rebinds names even after scope of comprehension. Is this right?
...y found was single-value for clauses eg. sum100 = [s for s in [0] for i in range(1, 101) for s in [s + i]][-1], but just needs a comprehension-local var and works just as well in Python 3. I think "leaking" was the only way to set variable visible outside an expression. Everybody agreed these tech...

In a recent interview, I was asked a really strange question. The interviewer asked me how can I compute 1+2+3+...+1000 just using compiler features. This means that I am not allowed to write a program and execute it, but I should just write a program that could drive the compiler to compute this su...

Convert a list to a dictionary in Python
...mprehension, but ironically I think the simplest way to do it will be with range() and len(), which would normally be a code smell.
b = {a[i]: a[i+1] for i in range(0, len(a), 2)}
So the iter()/izip() method is still probably the most Pythonic in Python 3, although as EOL notes in a comment, zip(...
