Where does ‘Hello world’ come from?
Why are most all programming examples written to print the specific phrase Hello World? Sometimes you see derivatives like ohai world and such, but always branching from Hello World. Does anybody no why this is?
simple program like this gives a good example of the syntax of the language, structure of the program, things like that.

How to use HTML5 features with XHTML
(2 answers)
Closed 4 years ago.
I have seen on several occasions that some companies are looking for web developers who know how to program in html5 and xhtml. I wonder why they specify xhtml. I do not know if these languages are used separately or if you can join strengths in the same file.
I'm sorry if my English is not very good and if my question is novice. Thank you
XHTML is an older architecture based on html4, it's possible to keep old applications alive

There are a lot of people who are afraid of copyright infringement, but as mplungjan said
If you put it on the web, it will be available to look at.
And that, unfortunately for you, is the case for every site from Google to Stack Overflow.
If there are any bad cases of your site being plagiarized you should think of suing.

I have just scratched the surface in the world of programming, and I need to know where to begin. I work for a Web-page writing articles, and I face a raise if I learn to format the article myself. I want to learn how to format, and also how to code. Is there anywhere in particular where I should begin my journey to programming things such as web-applications?
The following are just a hint. This journey is quite long and after a basic level, you have a multitude of options...
First of all: learn HTML. There's nothing to do if you cannot understand the content you're creating.
Learn CSS - this will help you to achieve the formatting in the right way and will make you understand how web pages are styled. That's where the fun begins, with knowing some CSS you will be able to make a web site look good.
Get a decent code editor for working, prototyping. If you really want to understand what's going on, then prefer non-WYSIWYG editors (you will see what I mean). The more decent you can get the better - this will help you in your daily work, better to not choose one which is irritating for you. (Personally I use PhpStorm which is a really good, professional tool. It might be too advanced for beginners.)
All web pages nowadays are created dynamically, for example via PHP. Learning to code in PHP will make you busy for quite a bit of time, so it would be the best to get a good book about it. (This will also start you up learning about databases, where the actual information is stored.) In my opinion, this is where the real part of web programming begins.
After writing some basic stuff with PHP, get familiar with different frameworks/CMSs just to know how we deal with big, real sites. (WordPress is great for starting and it's advanced enough to use it on a real site.) There's no point in reinventing the wheel, so always try to have a look whether others have done what you would like to do before. There's always a toolkit for the common tasks.

Difference Between Single and Double Quoted Strings in ActionScript
Hello I have a simple question that I hope you can answer. I have been programming in actionscript for three months and I am very new to a lot of the details. I was programming in java in which there is an important difference between 'hello' and "hello".
So my question is:
In actionScript is it the same to use 'Hello' and "Hello". If not what are the differences???
Thanks a lot!!!
Yes, it's the same thing. I'm sure this will answer your question, since it's been asked before.

Hello I have an html page that through php pulls reports about sales and puts them in charts and graphs. It works great however I am looking for a way to convert a div box into a pdf so whoever is using the sight can print specific graphs and charts that are in selected div boxes. Is there a simple way to do this or is this unfeasible?
Thanks!
There are lots of answers here merely talking about making a PDF. That's the easy part - the hard part is finding an engine that renders the CSS well.
This question has been raised before, and the issue doesn't lie with feasibility (it's very possible and there are lots of solutions), but they vastly differ on their capabilities to translate CSS into PDF. Many just completely fail altogether.
From my research it looks like WKHTMLtoPDF is your best bet, as it uses a full WebKit engine to render the HTML first, then translate that into a PDF (I found a tutorial in addition to the docs).
The downside? It's command-line, so you'll need to engineer a solution involving either python or php to execute the program. Here's the PHP manual on executing a program.
Edit:
I have personally used FPDF before, which is a surprisingly light-weight solution with a caveat that you have to provide it with all of the HTML (edit:) line-by-line, rather than being able to use the browser-rendered result of a HTML page (a result that would include a rendered chart). I'm providing it merely as a suggestion and to help you work out where you can go from here, but it's not directly applicable to your complex CSS/chart problem.
