Run your web applications on Google App Engine

Posted on by

Google App Engine lets you run your web applications on Google’s infrastructure. App Engine applications are easy to build, easy to maintain, and easy to scale as your traffic and data storage needs grow. You can serve your app from your own domain name or from a free name on the appspot.com domain.

Google App Engine supports apps using standard Java technologies, including the JVM, Java servlets, and the Java programming language—or any other language using a JVM-based interpreter or compiler, such as JavaScript or Ruby. App Engine also features a dedicated Python runtime environment, which includes a fast Python interpreter and the Python standard library. The Java and Python runtime environments are built to ensure that your application runs quickly, securely, and without interference from other apps on the system.

App Engine costs nothing to get started. All applications can use up to 500 MB of storage and enough CPU and bandwidth to support an efficient app serving around 5 million page views a month, absolutely free. When you need more resources and enable billing for your application, your free limits are raised, and you only pay for resources you use above the free levels.  There are no set-up costs and no recurring fees. The resources your application uses, such as storage and bandwidth, are measured by the gigabyte, and billed at competitive rates. You control the maximum amounts of resources your app can consume, so it always stays within your budget.

The Java runtime environment uses Java 6, the App Engine Java SDK supports developing apps using either Java 5 or 6. The Python runtime environment uses Python version 2.5.2. Additional support for Python 3 is being considered for a future release. App Engine provides a powerful distributed data storage service that features a query engine and transactions. Just as the distributed web server grows with your traffic, the distributed datastore grows with your data. You can register up to 10 applications per developer account.

SDK’s are available for Java and Python, a plugin for Eclipse exist, Getting Started guides and other documentations are available at the Google App Engine website.

Informations about prices, billing and budgets are also available on the website. A direct access to the login page is here.

Limit my bandwith on Amazon S3

In 2006, a developer raised the question in the Amazon Discussion Forum whether there is a risk that the bandwidth cost grow beyond a level he was not willing to pay for. AWS answered that such a feature is in the work. The plan was to enable users to cap how much they are charged each month.

Three and a half year later, this is still a plan. The latest message from AWS was : later this year (2009) or early next year (2010).

TinEye, PixID, Piximilar : advanced image software by Idée Inc.

Posted on by

The canadian company Idée Inc. was founded by Leila Boujnane (CEO) and Paul Bloore (CTO). The company develops advanced image identification and visual search software.

PixID is an innovative video and still–image identification system that analyzes each client’s visual assets and actively tracks where their images have appeared, both in print publications and on the Internet. Idée’s proprietary software creates a digital fingerprint for each client image and compares it to images scanned from publications and crawled from the web.

Piximilar allows users to analyze, index and search quickly and efficiently through vast image and video collections based on visual similarity. Piximilar’s visual similarity technology uses sophisticated algorithms to analyze hundreds of image attributes such as colour, shape, texture, luminosity, complexity, objects and regions. These attributes form a unique visual signature.

With the Multicolr Search Lab, you can browse through 10 million of Flickr’s most ‘interesting’ Creative Commons images, and find ones that share the same colours. Choose up to 10 colours from our palette of 120 different shades.

TinEye is the first image search engine on the web to use image identification technology. Given an image to search for, TinEye tells you where and how that image appears all over the web—even if it has been modified. Just as you are familiar with entering text in a regular search engine such as Google to find web pages that contain that text, TinEye lets you submit an image to find web pages that contain that image. A beta version of TinEye is operationel.

TinEye Mobile allows you to search for products using your mobile phone’s camera.

The Idée Labs offer two other applications : Visual Search Lab and BYO Image Search Lab, both from the Alamy Stock Photos.

MapLib : Turn any image into a Google Map

Posted on by

MapLib is an application created by Xiao Yisheng that allows you to upload a large image and instantly apply the Google Maps interface to it for easy viewing. Upload an image as large as 6000 x 6000 and embed it on a website with the Google Maps viewing interface. Large images with abundant depth and detail can be annotated. Detailed business related product photos can be described by owners or other visitors to the image. A large photo with many people or places can be annotated like a Google Map.

MapLib API is still in beta stage. There may be some unexpected bugs. MapLib offers free accounts with limited features, pro accounts for 35 US$ per year with enhanced features and super accounts (call for price) with unlimited features. MapLib.net provides a javascript API to embed generated pictures in a user’s own webpage, with full flexibility.

MapLib offers also a solution called Integrator to let you host the generated maps on your own server, which means, all the generated information, including pictures, php files, javascript files, html files and markers. This allows to make the maps running without connecting to MapLib.net every time. The prices without full sources are 120 US$ for the advanced single site solution (maximum 10 maps) and 300 US$ for the premium single site solution (unlimited number of maps). For the solutions with full sources, to customize the presentation, the prices are 200 US$ and 500 US$.
