Complexify is a jQuery plugin for accurately telling users how secure is their password.

The developer puts the motivation behind this plugin very succinctly:

If your password is 8 characters long and only formed of lower case characters, you need to make it better, perhaps by adding a number or more characters.

If your password is 25 characters long but happens to not contain a number, you shouldn’t be forced by a password security policy to add one, you clearly have a very secure password.

The minimum criteria for a password’s complexity are quite satisfactory: a minimum-security password should take at least 600 years to crack on a commodity machine.

Verbose Calendar is a calendar plugin for jQuery that prints out the whole year in months and days.

Verbose Calendar can be used for event planning in companies, or even an OCD-driven to-do list.

Puns aside, this plugin is quite peculiar, but placing the nuts and bolts are left up to you as this Calendar ships with but a few events.

JamCity is a jQuery plugin for fetching the top tracks and albums from a given last.fm account.

The plugin, upon fetching the information needed, outputs a beautiful layout of things that were requested.

JamCity, I imagine, can be useful for music blogs and review sites, and for personal websites, too.

Using JamCity requires a last.fm API key, but it’s really easy to obtain.

Super Labels is a plugin for adding labels on top of input and select fields.

The plugin comes with several options, most of which are pretty straightforward and expected, and the easing option seems to bet the most useful in terms of design.

Super Labels is licensed under the generous MIT license.

OmniWindow is a jQuery plugin for creating modal windows.

At 139 lines and 6kb (not minified), OmniWindow is an impressive programming feat, given its customizability and options.

OmniWindow stores CSS externally, and allows for a minimum of customziation options, although not aspiring to be a ‘plugin template’, as OmniWindow can be used on its own.

It features two events — show and hide — and a number of callbacks for implementing animations.

Dynamo is a jQuery plugin for adding dynamic bits of content to your websites.

The plugin works by simply ‘cycling’ content up or down, e.g., replacing one word with another.

The subtle effect (well, its subtle-ness depends on where you use it) is great for adding variety to content, and perhaps for sparing a few adjectives here and there.
