Having a github and a portfolio for me is 2 entirely different things, github is for management and building while my portfolio is my marketing.

I get that you can do these things and there is nothing wrong with doing so if its private, however if you want to monetize it you should treat it like a buisness.

Having gmail and such things only makes me think its an unproffesionel buisness, and i they wont hear from me again. Its fine using gmail and forwarding mails to it again 2 different things, but if you have to hand out a portfolio to people its alot easier having an address, that first of all is easy to remember, and not geoshitties.getpooanal.something.com. Think of the end user and who you want to project yourself onto.

All of this is important, while you can do it the other way it just makes it harder for your
self.

Then in the end what is 20$ a year for a proper site ?

It's not a portfolio for getting work really, it's more of a hobby. Somewhere to document various things I make/have made. Somewhere to show off the things I'm proud of, you know? I will bare what you've said in mind, however. If it does become something more than this, I'll be sure to migrate a better host.

His point about the domain name is completely moot in this case because you can [url=https://help.github.com/articles/setting-up-a-custom-domain-with-github-pages]easily associate your own domain name with a GitHub Pages site[/url]. As for e-mail, well, you don't need to set up your own server, either. You can just rely on a cheap mail hosting provider with support for custom domains.

Just a quick opinion thing - I've decided that Java is too much of a pain in the ass to set up and use for web development and I'm trying to avoid PHP like the plague. Would you guys consider Ruby to be the best alternative here?

I've got absolutely 0 experience with Ruby but I'm hoping to set up a web server on a VPS with 512MB of RAM and 1 CPU core to handle very low traffic on a web application that'll access a MySQL database - is this doable? I know with PHP it is (Apache + MySQL or NGINX + MySQL if you're really after performance) but again I'm looking to stay away from PHP.

Basically I'm asking if you guys think Ruby is a good route to take and how easy it is (in comparison to PHP and Java) to get a server up and running. PHP is pretty easy, a few apt-get commands and you're good for a very basic install. Java has proven to be a PITA. I haven't looked into Ruby yet since I'd rather not waste my time like I did with Java which is why I'm checking in here.

Ruby and Node are both easy to install, and of those, I'd say Ruby's the easiest to learn. Just install ruby (if it's not already installed, that is) with [URL="http://rvm.io/"]RVM[/URL], and then it's just as easy as just executing the main file after writing the site. You can also use Nginx as a proxy for it, which is a bit more work, but it's not that hard.

If you have knowledge with frameworks before, Ruby & Rails would be a good alternative. I've seen the power it holds, but I've never gotten attached to it.
As a PHP guy here, I didn't understand jack shit of it at first. For me, it looked more like a command-line language instead of actual code. [I]Install a gem here and there, add a line there and there and run this command and you're done[/I] type of language.

Before you step into Rails, you should really learn a good portion of Ruby first. Otherwise it's like learning CodeIgniter/Symfony before learning PHP. It'll be a hefty task, but probably worth it in the end.

To get RoR running on your VPS, get [URL="http://www.modrails.com/documentation/Users%20guide%20Nginx.html"]nginx with the passenger module[/URL] or use the gem [URL="http://code.macournoyer.com/thin/"]thin[/URL].

Many RoR's likes thin, while passenger is [URL="http://izumi.plan99.net/blog/index.php/2008/03/31/benchmark-passenger-mod_rails-vs-mongrel-vs-thin/"]faster[/URL]. Although that post is from 2008, thin or passenger might've been drastically improved. Found an interesting answer about this matter from an author of passenger on [URL="http://stackoverflow.com/a/13154077/1765851"]stackoverflow[/URL].

I'd suggest [url=https://github.com/sstephenson/rbenv]rbenv[/url] over RVM. It's easy to set up and really just focuses on managing which versions of Ruby are installed. They both do the same thing in that regard, though, so just make your pick. (And stay away from RVM's "gemsets" - if you want to manage your application's dependencies, just use [url=http://bundler.io/]Bundler[/url]. It doesn't depend on RVM.)

[QUOTE=supersnail11;44757891]You can also use Nginx as a proxy for it, which is a bit more work, but it's not that hard.[/QUOTE]

I second that. The benefit of it is that your Ruby server needn't serve static assets like images, JS or CSS. nginx is really fast at serving static files, even more so than Apache. It's also (subjectively) easier to configure for me, especially when it comes to things like rewrites. If the site has very low traffic, though, as you said, it doesn't matter at all.

[QUOTE=Svenskunganka;44757969]If you have knowledge with frameworks before, Ruby & Rails would be a good alternative. I've seen the power it holds, but I've never gotten attached to it.[/QUOTE]

Depending on how large the application should be, using something like [url=http://www.sinatrarb.com/]Sinatra[/url] together with [url=https://github.com/sinatra/sinatra-contrib]sinatra-contrib[/url] and something to handle SQL database stuff (sinatra-activerecord, sinatra-sequel, ...) might do a great job. Funnily enough, I'd rather suggest Rails to a newcomer, though - it's more integrated as it doesn't require you to manually add and install tons of other things, and there's a [url=http://guides.rubyonrails.org/]boatload of documentation[/url] at your disposal.

[QUOTE=Svenskunganka;44757969]To get RoR running on your VPS, get [URL="http://www.modrails.com/documentation/Users%20guide%20Nginx.html"]nginx with the passenger module[/URL] or use the gem [URL="http://code.macournoyer.com/thin/"]thin[/URL].[/quote]

If you don't plan on using nginx for the aforementioned reasons, Thin is really neat.

I'm trying to create a "playlist" kind of thing where you can click items in the main browser window, and it will bring them into a list for comparative analysis in a new window.

This is the code I'm using now:

 if (jQuery.inArray(event.start, dateArray) > -1) {
   dateArray = $.grep(dateArray, function(value) {
      return value != event.start;
   });
   arrayInc--;
   window.alert("Already in Array");
}
else {
   dateArray[arrayInc] = event.start;
   arrayInc++;
   window.alert("Added to array");
}

$.ajax({
   type: "POST",
   data: {data:dateArray},
   url: "explore.php",
   success: function(msg){
      var w = window.open();
      $(w.document.body).html(msg);
   }
});

The main window is a calendar, and the items are events in the calendar.
The problem with my current code is that it opens a new window every time an event is clicked, rather than updating the already open window.

Does anyone know how to make this work?

You have
var w = window.open();
$(w.document.body).html(msg);
in your code. window.open() opens a new window, so it's doing what you tell it to.
If you want to update the already open window, you should do something like $(this).html(msg) , which will change the current page's HTML for the one in msg.

I get that, I'm just wondering how I would reference that open window to update the content.

[djjkxbox360]

Well you don't have anything in your window.open, you need a file for the window to open. Then you have your script in that file

My php-fpm is running as apache and prevents any and all connections for a user when that user is asking for another page after aborting the loading of a page.

array_rand returns a random [B]key[/B]. This means, you need to do $a[BG].

What's the rest code that works with BG?

(Also, 1 is the default, so it's not needed there)
(Also, you've included bg_blue two times. Just in case it was appearing too many times...)

I'm a bit unsure how I should approach this:
I have a website with an open market. Anyone can sell things on there (from a specific game), but the item that’s sold is a one-time selling.
So, when people buy itemX they pay using PayPal where the money goes directly to the seller. I get the IPN and send them the item.

My problem here is that if two individuals decide to buy this item almost at the same time. After they’ve selected ‘Pay now using PayPal’, I have no way of telling them that somebody else was quicker in the payment process and purchased it?
I’ve considered making the item unavailable as soon as a person clicks the ‘Pay now using PayPal’ button, but this could be abused pretty much couldn’t it?

I'd recommend switching to PDO. The mysql_* library is deprecated and just crap in general. PDO has prepared statements (which means proper SQL injection prevention) and much better error handling.

[roekelt]

Yeah, i got a config.php... this file is included in a index.php which already has config.php included.

Are you sure your query returns something? If there is nothing to select it won't show anything. Oh and use PDO or mysqli.

Is there any easy way to override a title on a page?
I want to have a default, generic title just in case I forget about it or something. But, at the same time, I want to be able to change it easily on the pages I deem fit.

I originally thought about having the generic one on a template and then run that on each page, adding another <title> tag with the dynamic one after the template (so, two title tags), but that doesn't seem to work, needing to remove the generic one for the dynamic to display.

[editline]10th May 2014[/editline]

I know you can do document title with Javascript, but I'd rather only use HTML( or PHP) for this.

I don't think you can change it purely with html, with php couldn't you just echo something different inside the title tag instead of adding a new title? Like

<?php
$title = "This title";
?>

<title> <?php echo $title ?> </title>
