AjaxDaddy - Javascript Demos in Action

Demo that shows how you can use the webcam together with webrtc to detect motion in front of the camera. In this example this movement is used to control a space invaders game. All in HTML and javascript.

can't we just stop XSS dead in its tracks by modifying the words script, href, src, and http from any incoming input for user registration?

2012 July 27

And just to emphasize, I am talking only for user registration.

I mean, just adding spaces in between each character would be enough to render any malicious input useless. and depending on your userbase, how many people just cant live without inputting registration information that includes the specific character combinations of script, href, src, and http?

Maybe script, but that'd only be an issue with email, where making an actual user change their email would be ridiculous. And for that particular situation, email input would still have to go through validation anyways. can't really perform XSS with an @ and .domain requirement. and I can't think of a single word in the english language that uses the letters "src" in that order.

Am I on to something or is this a terrible idea?

JqueryUI has failed us

2012 July 27

There hasn't been even a .x release in TWO AND A HALF YEARS

1.8 came out in Jan 2010

Resig resigned a long time ago

There's plugins and stuff, but no native combo or grid. They've been on the "todo" for years.

JQueryUI is a massive, massive failure, and I don't know why you sheeple are holding on to it.

Please, let's just abandon it, and find something else.

Google Chrome vs Firefox: Chrome is Catching Up on Features for Web Developers

2012 July 26

Google Chrome browser seems to have practically reached the leadership of the market share of browsers among the generality of the users. However, Firefox still leads in the preference of the majority of Web developers. This article is a follow-up of another written last year entitled "Top 10 Reasons Why Firefox is still Better than Chrome for Web Development". This time it includes a point by point response from Renato Mangini of Google Chrome Developer relations team on the issues raised in the past article to explain which issues were addressed or can be overcome somehow. Read this article to learn more on how Google Chrome is catching up on Firefox, as well find out about other less known cool features of Chrome that can improve your Web user experience.

Starting a Django Project the Right Way

2012 July 26

One of the things I wish I had known when starting my Django project for IllestRhyme was "How do I start a real Django project". As in, one that's actually going to be used and developed more, not the toy project from the (admittedly execellent) Django documentation.

8 Best JavaScript Plugins for June 2012

2012 July 26

The primary use of JavaScript is to write functions that are embedded in or included from HTML pages and interact with the Document Object Model (DOM) of the page. Because JavaScript code can run locally in a user’s browser (rather than on a remote server), the browser can respond to user actions quickly, making an application more responsive.

CSS 3D Folding Animation

2012 July 26

Google Plus provides loads of inspiration for front-end developers, especially when it comes to the CSS and JavaScript wonders they create. Last year I duplicated their incredible PhotoStack effect with both MooTools and pure CSS; this time I'm going to duplicate their map fold-in effect. This effect uses 3D CSS animations which makes the animation even more sexy, and to make it red host, the animation requires no JavaScript!

Explaining What JavaScript is to Non-programmers

2012 July 26

When I tell non-programmers that what I do professionally involves JavaScript, I most commonly get the reaction: “Isn’t that that thing that you have to install and that makes the browser slow?”. This answer surprises me in two ways

Thoughts on ECMAScript 6 and new syntax

2012 July 26

I am, just like many in the JavaScript world, watching anxiously as ECMAScript undergoes its next evolution in the form of ECMAScript 6. The anxiety is a product of the past, when we were all waiting for ECMAScript 4 to evolve. The ECMAScript 4 initiative seemed more like changing JavaScript into a completely different language that was part Java, part Python, and part Ruby.

New to javascript

2012 July 26

OK so I know from looking at the posts here that most of you guys are experts on JavaScript. I recently got the android app called AIDE ( it lets you write JavaScript and then run it on your phone without the need of a computer). I have really gotten into programming and wanted to start with JavaScript using this app (so that I can just experiment and make code wherever). The only problem is I don't even know where to start. I don't know if this is the right subreddit to ask but I need help as a begginer. I have looked at sites and they all just confuse me. My goal is to make a cool game I can say is mine (like RuneScape, but not that complex). Does anyone know a good site to learn from or have any information that would help? I have tried to make something but I just don't know the commands or the formate to type any of it. If you post anything to help, thank you.

What do you think about a vendor using Web SQL Database for a mobile app?

2012 July 25

I'm getting a first look at some vendor code for a mobile app and I noticed they're using Web SQL Database. I thought this was odd as I could swear Web SQL DB had been deprecated by the W3C. Sure enough, this looks to be the case, http://www.w3.org/TR/webdatabase/

I also thought Indexed DB was where client-side DBs were going, though I could certainly be wrong, I don't have a ton of knowledge here, just going from what I think I've read in the past.

I believe we only spec'd support for iPhone and Android.

What do you guys think about a vendor using a deprecated API? This seems really bad IMO as obviously the spec is not going to get updated, browser vendors that don't support it aren't going to start supporting it and I imagine will eventually drop support for it.

Again, I don't really have a ton of knowledge about client-side DBs, but this did jump out at me glancing at their code.

Help needed with confusing scopes in javascript

2012 July 25

I have been programming in languages like C, C++, Java, python etc. and have a natural tendency to assume a few things about the scope of a variable. Recently tried to do some javascript and ended up with very bizzare bugs related to scope (one function called another function which both used i for a counter and the second function was changing the value in the calling function).

Anyway is there a resource that clearly lays out how scopes work in javascript? Also I have just been writing code in notepad++ and running on chrome. Any good debugger I can use?

Lazy Loading RequireJS Modules When They Are First Requested

2012 July 25

I've been loving RequireJS as a framework that helps me think about my JavaScript applications in a more modular fashion. However, in my research and development, I've always been loading all of my RequireJS modules upfront, at the start of the application. As I've begun to move some RequireJS functionality into production, I've found myself not wanting to eagerly load modules that hardly ever get used. Rather, I'd like to lazy load some modules if, and only if they ever get requested by the user.

Powerful New CSS- and JavaScript-Techniques (2012 Edition)

2012 July 25

Coding a jQuery Popup Modal Contact Form

2012 July 25

In this tutorial I’ll demonstrate how we can build a minimalist modal contact form. I’ll be using jQuery along with the fancybox plugin to manage dynamic content. The open source code libraries make scripting so much easier. And we can implement a small Ajax call which submits the form data via PHP on the server end.

What is the best way to secure Javascript post redirect?

2012 July 25

So I am limited to using only Javascript to redirect users to a PHP page which will update the users record in a MySQL database. I started with a basic redirect but this method can be bypassed by pointing to the URL of the PHP page. So to fix this, I used Javascript to POST a form to the PHP page where a variable was being expected by the PHP page. This can be easily bypassed if the user takes a look at the POST using a web tool. What is the best way to secure a page like this? If I use a common shared key, it will be in plaintext if you view the source from your browser. Any pointers or links will help.
