Create a nonclustered non-unique index within the CREATE TABLE statement with SQL Server
...me with last name starting with A; index on the FK doesn't help. In other words, I'm not sure that "because you join on it you should index it" is good practise. Am I missing something?

Passing a 2D array to a C++ function
...for this. But, that's the whole point! The compiler takes the programmer's word in faith and if the programmer was incorrect, undefined behaviour ensues. This is the reason I'd mentioned that case 4 is the least safest option.

Should unit tests be written for getter and setters?
... change to other. Compare with keeping requirements and design on separate word document.
Separate responsibility from implementation
As programmers, it is terribly tempting to think of attributes as something of significance and getters and setter as some sort of overhead.
But attributes are a...
Should composer.lock be committed to version control?
...
Perhaps the use of the word "coworkers" was confusing here, I changed it to collaborators. The main difference is "main project" vs library, in which a main project consists of one or more libraries and code to integrate those. When running compose...

When to use ' (or quote) in Lisp?
...that single value from all locations where the constant appears. In other words, it may treat the constant like an anonymous global variable.
This can cause obvious problems. If you modify a constant, it may very well modify other uses of the same constant in completely unrelated code. For examp...

Verify a certificate chain using openssl verify
...s found which is its own issuer it is assumed to be the root CA.
In other words, root CA needs to self signed for verify to work. This is why your second command didn't work. Try this instead:
openssl verify -CAfile RootCert.pem -untrusted Intermediate.pem UserCert.pem
It will verify your entire c...
Wrap a delegate in an IEqualityComparer
