How can I verify if one list is a subset of another?
...s the answer to your question, however.
A list may contain items multiple times and has a specific order. A set does not. Additionally, sets only work on hashable objects.
Are you asking about subset or subsequence (which means you'll want a string search algorithm)? Will either of the lists be t...

What is the difference between Trap and Interrupt?
...nded and continues afterwards). In a sense they are "active" - most of the time, the code expects the trap to happen and relies on this fact.
An interrupt is something generated by the hardware (devices like the hard disk, graphics card, I/O ports, etc). These are asynchronous (i.e. they don't happ...

How many database indexes is too many?
... be very slow with lots of indexes since they all need to be modified each time one of these operations takes place
Having said that, you can clearly add a lot of pointless indexes to a table that won't do anything. Adding B-Tree indexes to a column with 2 distinct values will be pointless since i...

How are people unit testing with Entity Framework 6, should you bother?
... as a previous answer stated it's often pointless to spend vast amounts of time testing what you don't own.
However, you do own the database underneath! This is where this approach in my opinion breaks down, you don't need to test that EF/NH are doing their jobs correctly. You need to test that you...

What dtypes exists?
We have access to numpy dtypes: float, int, bool, timedelta64[ns] and datetime64[ns]. Note that the numpy date/time dtypes are not time zone aware.
Pandas extends this set of dtypes with its own:
'datetime64[ns, ]' Which is a time zone aware timestamp.
'category' which is es...
What does “DAMP not DRY” mean when talking about unit tests?
...ode. To understand it, you have to read it. Consider for a moment how much time you spend reading code. It's a lot.
DAMP increases maintainability by reducing the time necessary to read and understand the code.
DRY (Don't repeat yourself) promotes the orthogonality of the code.
