SubEtha SMTP is a Java library which allows your application to receive SMTP mail with a simple, easy-to-understand API. This component can be used in almost any kind of email processing application. Hypothetical (and not-so hypothetical) uses include: A mailing list manager (see SubEthaMail ) A mail server that delivers mail to user inboxes A mail archiver like The Mail Archive An email test harness (see Wiser ) An email2fax system SMTPseudo A filtering forwarding server Baton SMTP proxy for one or more backends (rules based on sender/envelope) Mireka - Mail server and SMTP proxy with detailed logging, statistics and built-in, fail-fast filters SubEthaSMTP's simple, low-level API is suitable for writing almost any kind of mail-receiving application.

There is one difference between undefined And null in javascript :: undefined is a data type and null is a value defined empty variable is null of datatype undefined Both of them are representing a value of a variable with no value AND null doesn't represent a string that has no value Like var a = '' ; console . log ( typeof a ); // string var a = '' ; console . log ( a == null ); //false console . log ( a == undefined ); // false Now if var a ; console . log ( a == null ); //true console . log ( a == undefined ); //true BUT var a ; console . log ( a === null ); //false console . log ( a === undefined ); // true SO each one has it own way to use undefined use it to compare the variable data type null use it to empty a value of a variable var a = 'javascript' ; a = null ; // will change the type of variable "a" from string to undefined

Zakas Tags: Hoisting , JavaScript Last week, I tweeted about a JavaScript quiz I came across on Dmitry Baranovskiy’s blog entitled, So you think you know JavaScript? As with other quizzes of this type, there is only one question to answer for five different pieces of example code: what is the result? The example code tests some of the quirkier attributes of JavaScript engine behavior. I’ve seen similar quizzes in the past, sometimes by people saying that they use it as a test during job interviews. I think doing so is both disrespectful to the candidate as well as generally useless. You don’t encounter this type of quirk every day, so making that the minimum to get a job is about as useful as asking flight attendant candidate...

From: http://www.adequatelygood.com/JavaScript-Scoping-and-Hoisting.html Do you know what value will be alerted if the following is executed as a JavaScript program? var foo = 1; function bar() { if (!foo) { var foo = 10; } alert(foo); } bar(); If it surprises you that the answer is “10”, then this one will probably really throw you for a loop: var a = 1; function b() { a = 10; return; function a() {} } b(); alert(a); Here, of course, the browser will alert “1”. So what’s going on here? While it might seem strange, dangerous, and confusing, this is actually a powerful and expressive feature of the language. I don’t know if there is a standard name for this specific behavior, but I’ve come to like the term “hoisting”. This article will try to shed some light on this mechanism, but first lets take a necessary detour to understand JavaScript’s scoping. Scoping in JavaScript One of the sources of most confusion for JavaScript beginners is scoping. Actuall...
