Is 'switch' faster than 'if'?
... do things like using binary search on the values of the switch, which (in my mind) would be a much more useful optimization, as it does significantly increase performance in some scenarios, is as general as a switch is, and does not result in greater generated code size. But to see that, your test ...
Reverse a string in Python
...
What is the best way of implementing a reverse function for strings?
My own experience with this question is academic. However, if you're a pro looking for the quick answer, use a slice that steps by -1:
>>> 'a string'[::-1]
'gnirts a'
or more readably (but slower due to the method...
How important is the order of columns in indexes?
... it is inaccurate. It's is very admittedly extremely simplified, which was my intent. Your answer digging into far more detail about the levels is appreciated though, for those that want to dig deeper into it. If you look at your tree image, you'll see what I am illustrating in a very simple way. Th...
How do arrays in C# partially implement IList?
...ed it a lot, and explained why the CLR treats arrays oddly - but I believe my answer of explicit interface implementation was pretty correct before. In what way do you disagree? Again, details would be useful (possibly in your own answer, if appropriate).

db = SQLAlchemy() # Initialize the Flask-SQLAlchemy extension object
db.init_app(app)
Then t...
Why is “except: pass” a bad programming practice?
...ption type after except, and simply passing it without taking any action.
My explanation is “a bit” longer—so tl;dr it breaks down to this:
Don’t catch any error. Always specify which exceptions you are prepared to recover from and only catch those.
Try to avoid passing in except blocks. ...

Best approach for designing F# libraries for use from both F# and C#
... use in the other style. The wrappers can be in a separate namespace (like MyLibrary.FSharp and MyLibrary).
In your example, you could leave the F# implementation in MyLibrary.FSharp and then add .NET (C#-friendly) wrappers (similar to code that Daniel posted) in the MyLibrary namespace as static ...
Fastest sort of fixed length 6 int array
... at least sorting networks and insertion sort. If I were betting, I'd put my money on insertion sort based on past experience.
Do you know anything about the input data? Some algorithms will perform better with certain kinds of data. For example, insertion sort performs better on sorted or almos...
