Email signature etiquette

Folks… If the signature of your email is longer than the actual message you’re conveying, it’s TOO LONG!!!!! A signature is just that … A SIGNATURE. Not the prospectus of your company.

Name, contact information. That’s IT. And if you can compact your contact info to a few lines, instead of 6, 7, 10 lines, PLEASE do it. There was a time where signatures would be truncated if they went past a certain number of lines. You don’t have to split your job title or company url to another line. That saves a couple of lines.

[name] – [job title]
Phone: (###) ###-####
[company name] <>

Bang. Nice and compact. Respectful. My signature? Two lines. TWO.

name / email
job title / websites

That’s it. Listen and learn.

Sometimes technological advancement isn’t all it’s cracked up to be.

JavaScript Tip – Invert Logical Expressions With De Morgan’s Laws

Just something I want to keep around for reference. Ignore if you don’t program. – matte

Reprinted from SitePoint Community Crier #71. Without permission but credit is given. 🙂

A JavaScript expression will sometimes be more intuitive (and easier to understand) when written a certain way, but, often, we may actually need the inverse of that expression. For example, in Listing 1 below, our code only needs to react if (x && y) is false. We need to invert the expression.

Listing 1

if (x && y)
// we don't have anything to do here
// we want to do something here

De Morgan’s laws describe how to invert a logical expression. In Listing 2, we see De Morgan’s Laws in action within the JavaScript syntax.

Listing 2

!(x || y) == (!x && !y)
!(x && y) == (!x || !y)

The rule inverts each logical term and each logical operator.

In Listing 3, we invert the expression from Listing 1 by applying De Morgan’s Laws.

Listing 3

if (!x || !y)
// we want to do something here

Sometimes, a logical term is more complex than a simple boolean variable. A logical term may be a relational expression, such as (p <>= q)
Inverting the next logical term (r != s) we get (r == s)
Inverting the logical operator && we get ||
The result is shown in Listing 5.

Listing 5

if (p >= q || r == s)
// we want to do something here

So, if you find yourself struggling with a JavaScript problem, pick up an old math textbook — your solution is probably in there.

Visit us at the SitePoint JavaScript Forum if you have any questions.

Keep it fun 🙂
