Free HTML templates

Well, here is a showcase of websites that offer free web templates. Just in case you don’t know, a website template is a web design that allows you to build a website or a blog. Besides, website templates are easy to edit and customize. Don’t you agree it takes less time and efforts to replace the default content with a custom one than create a brand new design? - see more here. Top 20 Sites to Download Free Website Templates.

Access to iPhone's gyroscope from web

This week's release of iOS 4.2 for iPad and iPhone comes with some nice little features most people will not immediately become aware of as they're neither directly visible in the iOS UI nor are they mentioned in Apple's official release notes. You have to dig a little deeper to find them. One of them is a JavaScript API for the iPhone's gyroscope. Read on to see it in action and learn how to use it.Your iPhone has a number of sensors, some of which are rather essential for the phone's operation (such as the microphone). While the accelerometer and the gyroscope might not be the most essential sensors for a phone, they're certainly the most exciting ones. While accelerometer measures the acceleration you induce on the phone, the gyroscope gives a rather precise feedback on the orientation of the phone - see how to do that.

Geo fence

Wikipedia defines geo fence as a virtual perimeter for a real-world geographic area.

A geo-fence could be dynamically generated - as in a radius around a store or point location. Or a geo-fence can be a predefined set of boundaries, like school attendance zones or neighborhood boundaries. Custom-digitized geofences are also in use.

When the location-aware device of a location-based service (LBS) user enters or exits a geo-fence, the device receives a generated notification. This notification might contain information about the location of the device. The geofence notice might be sent to a mobile telephone or an email account.

A great example of Geo fencing application - Footprint feed

YQL on practice

The Yahoo! Query Language (YQL) provides a unified interface to multiple third-party web services, allowing you to search, add, update, and delete data through a simple, SQL-like syntax. Combine powerful XML processing tools in PHP with YQL and you can easily add data from online services to a web application quickly, efficiently, and without wading through pages of API documentation - how to use YQL.

This article describes YQL and PHP. Java web developers can use YQL taglib from Coldtags suite for the same task.

A couple of components let you add file editor to your web applications: Notepad servlet and Edit file taglib

Like for real objects

Like button from Facebook could be placed on the mobile web pages too. And if this mobile page is devoted to some real business (place, location) than the word "Like" has got a very real sense – who from your real friends recommends this business.

Our new mashup Place card is an example for such kind service. This mashup lets you create a short mobile page with business description (text, address, contact phone and email) as well as an appropriate QR-code. This mobile page contains Facebook Like button. This QR-code could be placed on the real objects. So as soon as this page is scanned your visitor will see who from his/her friends in the social network likes (recommends) this business.

mod_pagespeed filters for Java servers

mod_pagespeed improves web page latency by changing the resources on that web page to implement web performance best practices. Each sort of change that mod_pagespeed makes is embodied in a filter. The filters are run in a pre-defined order, but can be enabled and disabled in the Apache configuration file. Here is the list of filters from Google.

Interesting, that many of the tasks could be solved for Java servers (e.g. Tomcat) with the help of controls from Coldbeans. Just a few of examples:

- Extend Cache - Public cache filter
- Collapse Whitespace and remove comments - Trim filter
- embed image via Data URI: Embed Image taglib

etc. Check out more at Coldbeans site

Currency format

Service utility for JSP developers: format currency

Share mobile files

QR code Our mashup - mobile files bookmark has been updated. Mobile site: http://mfile.linkstore.ru. You can load this link right to your phone with QR code above.

This application helps you share local files from your phone. Service lets you create bookmarks for files (e.g. media data) from your phone. File size – up 1 Mb. The goal is very simple - lets you quickly share local content: send pictures to friends, share music files etc.

For each local file service creates a separate mobile web page (bookmark) that lets readers download this file or share it with the own friends.

The usage is very simple, you do not need any registration. For sharing your local file go to mobile site http://mfile.linkstore.ru, type file name and upload the file itself. After that you can bookmark the mobile page created by the service or directly share your file - send link to it via email/sms or even let other people load it directly with QR code on your phone.

On the desktop level you can see a service Mobile page. See for example its description here

Secret places

Google Places API. With all the usage restrictions it is better to drop any idea about its deployment :-)
Foursquare is a way better. Mashups like Places and Forumsquare use Foursquare API.

Web 2.0 companies

"Digg’s collapse has become a cautionary tale for so-called Web 2.0 companies in Silicon Valley, even the current crop of superstars, like Facebook and Twitter. The basic problem is that these new-media companies don’t really have customers; they have audiences. Starting a company like Digg is less like building a traditional tech company (think Apple or HP) and more like launching a TV show. And perhaps, like TV shows, these companies are ephemeral in nature. People flock in for a while, then get bored and move on." - a great article from Newsweek.
