Using IQueryable with Linq
... against a remote database, with many ORM systems, you have the option of fetching data from a table in two ways, one which returns IEnumerable<T>, and one which returns an IQueryable<T>. Say, for example, you have a Products table, and you want to get all of the products whose cost is ...
Where do you store your salt strings?
...lted-hash of the password. The application is aware of this design so can fetch this data, and obtain the salt and salted-password hash.
My rationale for this approach:
If the password/hash data is compromised and falls into the hands of an attacker, the attacker will not know what the salt is fro...

...ing symmetric keys, asymmetric private keys, salt values, security tokens, etc.
However security-grade random numbers is a separate industry worth a separate article.
In most cases Pseudo-Random Number Generator is sufficient - e.g. for scientific simulations or games. In some cases consistently def...

What is a raw type and why shouldn't we use it?
...ing <?> as a type parameter?
List<Object>, List<String>, etc are all List<?>, so it may be tempting to just say that they're just List instead. However, there is a major difference: since a List<E> defines only add(E), you can't add just any arbitrary object to a List&l...
Why is x86 ugly? Why is it considered inferior when compared to others? [closed]
...on is often to look at the flags register to check for overflow, sign bit, etc. If there's another add after that, it's very difficult to tell whether it's safe to begin execution of the 2nd add before the outcome of the 1st add is known.
On a RISC architecture, the add instruction would specify th...
