Most of us create identities across the web without much conscious thought. We fill in profiles, upload photos, videos, reviews, and bookmarks. Although this information is often public, it’s fragmented into the silos of individual websites.

Glenn Jones built a JavaScript library that can help you do just that. Ident Engine discovers and retrieves distributed identities and profiles from across the web. Simply enter your profile URLs, you would be shocked by the level of detail it found out about you. You can also find out how Ident Engine works on A List Apart: Discovering Magic as well.

Lazy loader is a jQuery plugin written in JavaScript. It delays loading of images in (long) web pages. Images outside of viewport (visible part of web page) wont be loaded before user scrolls to them. This is opposite of image preloading.

Using Lazy loader on long web pages containing many large images makes the page load faster. Browser will be in ready state after loading visible images. In some cases it can also help to reduce server load.

There are options for control maniacs who need to fine-tune. You can set threshold on how close to the edge image should come before it is loaded. You can also set placeholder image and custom event to trigger loading. You can check out the demo with FadeIn Effect enabled.

jCryption is a javascript HTML-Form encryption plugin, which encrypts the POST/GET-Data that will be sent when you submit a form. It uses the Multiple-precision and Barrett modular reduction libraries for the calculations and jQuery for the rest. jCryption is completly free and dual licensed under the MIT and GPL licenses like jQuery.

Normally if you submit a form and you don’t use SSL, your data will be sent in plain text. But SSL is neither supported by every webhost nor it’s easy to install/apply sometimes. So I created this plug-in in order that you are able to encrypt your data fast and simple. jCryption uses the public-key algorithm of RSA for the encryption.

jCryption at it’s current state is no replacement for SSL, because there is no authentication, but the main goal of jCryption should be a very easy and fast to install plugin which offers a base level of security.

If we could drag our tabular data into grids from other programs we could circumvent the need to upload a data file to a web server to be read and parsed, then spit back out to our browser in a readable format.

Anyone who has ever had to parse Excel files on the server side knows how much of a pain it is, we might be lucky if we get a CSV file or some other simple format, but in the real world the end user running their spreadsheet program has no clue what simple tabular data is.

Shea Frederick has created a DataDrop plugin that is used on an ExtJS grid, giving that grid the ability to accept data dragged from spreadsheet programs such as Excel and OpenOffice Calc right into the grid to create rows of data.
