What is a Context Free Grammar?
...You are describing deterministic finite automata, which provide a decision procedure for regular languages ("decision programs which do not have memory"). Regular expressions are terms that denote regular languages, not programs are procedures. This was my sole complaint.

Why is IoC / DI not common in Python?
...rt it to inject it yourself? The chosen answer is right, since java has no procedural sections (code outside of classes), all that goes into boring configuration xml's, hence the need of a class to instantiate and inject dependencies on a lazy load fashion so you don't blow away your performance, wh...
How can I store my users' passwords safely?
...eve the password hash anyway, using a user specific salt will not make the procedure any more expensive. (Or did you mean generating a new random salt is expensive? I don't really think so.) Otherwise +1.

Simple explanation of clojure protocols
...ity in a language?
It turns out that for typical naive implementations of procedural and/or functional programming, it is very easy to add new operations (procedures, functions), but very hard to add new data types, since basically the operations work with the data types using some sort of case dis...
List or IList [closed]
...nce reasons you could always swap from returning a List<T> from your procedure to returning a T[], and if the procedure is declared to return IList<T> (or perhaps ICollection<T>, or IEnumerable<T>) nothing else would need to be changed.

What's the difference between an inverted index and a plain old index?
...we call it "index". But in search engines we suddenly call this exact same procedure "inverted index". Not because it's fundamentally different, but because we first created a "forward index" (split text) and then "inverse" it. So, all in all, the name "inverse" comes from the process of creating it...
Getting started with Haskell

Let's analyse each route in turn:
(GET "/" [] (workbench)) -- when dealing with a GET request with :uri "/", call the function workbench and render whatever it returns into a response map. (Recall that the return value might be ...
How to check which locks are held on a table
...g problems.
There are multiple different versions of "friendlier" sp_lock procedures available online, depending on the version of SQL Server in question.
In your case, for SQL Server 2005, sp_lock is still available, but deprecated, so it's now recommended to use the sys.dm_tran_locks view for th...
When is a language considered a scripting language? [closed]
... written in C, whereas a lot of Java or C# code you see on the web is very procedural and not object-oriented at all. OTOH, I have seen some heavily functional Java code.
So, if functional programming and object-oriented programming are merely styles that can be done in any language, then how do yo...
