Make sure your computer isn't infected with malware. There are various online malware scanners, plus various free tools to remove and prevent (preventing is much easier than removing) malware. You can also check load points by hand; autoruns is quite helpful in this task. Some malware will...

Presumably, `poll_length`has type INT. The maximum size of an INT is 2147483647 (signed) and 4294967295 (unsigned). Setting poll_length to 52254720000 is the problem (it's out of the range of valid INTs). 52254720000 seconds is 86400 weeks (52254720000 / (60*60*24*7); 86400 also happens to be...

Rather than stripping bad tags (blacklisting), allow only good tags and attributes (whitelisting) or use a lightweight markup language (e.g. BBCode, like the X10Forums, or MarkDown). If you end up allowing any HTML, don't write your own parser; use PHP's DOM or one of the other XML parsers.

In terms of sites you develop, consider page access (which cross-domain restrictions help secure) and injection attacks (which is entirely up to you to prevent).

Searching (the first thing you should do when you have a question) for "open ports" or "fsockopen" would reveal the answer: no.

Normally, I'd say that if you want help, include a description of both the behavior you expect and the behavior you get. In this case, I won't offer any help. The script probably breaks Google's Terms of Service and might be illegal. Passing of Google's translation services as your own is...

Some things, such as using JSON.stringify and the functional programming techniques I used for xml2obj (closures and first class functions), can easily wait. You should hold off on others, such as using objects or multi-dimensional arrays, only if you're under a deadline, since they will result...

I'm not following most of your reasoning. Is this why you're joining and later splitting? Better to learn proper techniques than continue to practice poor ones. Objects and multidimensional arrays are hierarchical, like (most) modern file systems. Think of accessing elements like paths: var arr...

Do you have a particular exploit scenario in mind? The current iframe security model goes a long way towards securing iframes. Bugs in the implementation of same still present exploits, however, and XSS exploits are ever a problem.

Put it in a single object, or hide the additional functions in the scope of another function, but monolithic functions are a bad thing. As with the larr issue, they hide problems due to being hard to read. Another issue that's hard to see (and the source of the problem with the service, supplier...

If only E4X was supported on more browsers. Try breaking down the one large function into smaller functions, each of which performs a single, well-defined task. You'll notice things like you're overwriting larr each time through the for (var l loop.

Whenever you're seeing server problems, check the Service Alerts forum (recent posts are also linked in the Server Alerts panel of cPanel, though that might not be accessible if the server is having problems). If you're on Chopin, you'll see that it's been under a DoS attack. It looks like it...

The right curly brace on line 94 matches the left curly brace after the "for (var o = 0; o < order.length; o++)" statement (line 38, by my calculations). It looks like you're missing a right curly brace before line 94. Look for an auto-indenting, paren-matching editor. Emacs is one option...

This thread belongs in the Programming Help forum. Perhaps an admin will move it. When asking for help with web development, include a link to a live page. As it stands, there doesn't appear to be enough information to diagnose the problem. Could you be more specific about the behavior you...

Iframes count as AJAX, believe it or not. XMLHttpRequest is just a newer option. Iframes are still used, especially if you want cross-domain communication.

Use AJAX rather than submitting the form. You can add a submit handler to the form that cancels the default action (to prevent the form handler page from loading).

Sorry, I had the wrong element (should have looked at the source first; the 2nd child is a <br/>). The sidebar is body :nth-child(4). Note you'll have to add the style inline, otherwise the current inline style will override your changes. Edit: nevermind about checking. The page style has...

KompoZer and Amaya both offer split-view editing, placing a rendered view of the page next to the source view (Amaya also offers a tree view & others, and lets you switch between a horizontal or vertical split layout). When you click on an element in the rendered view, KompoZer will display the...

Flyingt already changed the positioning, so the display problem is gone. What happens if you change the positioning of the sidebar div (body > :nth-child(2)) to "absolute" using Firebug? Thanks for reminding me. I forgot to report I tested on FF 3.5.6/Vista. Flyingt, what are your browser and...

That's what's so curious. I suspect a browser bug. I meant why the whole set-up. If the game div didn't have fixed positioning, you wouldn't have two scroll-bars, hence no need to set overflow on <body> to hidden. You could simply rely on <body>'s scrollbars. Setting the sidebar to fixed...
