Firefox 3.5 Launched..What Next…!? Firefox Aims to Unplug Scripting Attacks

The latest version of Firefox(3.5) is here with so many features……namely User Experience, Performance, Security, Customization…..!!

Still there is so much Firefox is looking ahead to……..Here is the most significant one which is up the sleeve…..

The matter of concern is how websites can block code from unknown sources. Here, firefox wants to Unplug Scripting Attacks.

IllustrationSites that rely on user-created content can unwittingly be employed to attack their own users via JavaScript and other common forms of Web code. This security issue, known as cross-site scripting (XSS), can, for example, allow an attacker to access a victim’s account and steal personal data.

Now the makers of the Firefox Web browser plan to adopt a strategy to help block the attacks. The technology, called Content Security Policy (CSP), will let a website’s owner specify what Internet domains are allowed to host the scripts that run on its pages.

XSS attacks have caused numerous headaches, particularly for social networks and Web 2.0 companies, allowing attackers to hijack eBay auctions, for example, and create a worm that caused MySpace users to automatically befriend a user named “Samy.” The core problem is that many sites allow untrusted users to add their own content to pages while Web browsers treat all content returned by a website as coming from the same entity. If the website is trusted, the content created by an unknown user is trusted as well. The issue has been counted as one of the 25 most serious coding problems by the SANS Institute, a training organization for system administrators and programmers.

In many cases, Web companies can hunt down and restrict dangerous user-created content. But because many sites are so big, finding and fixing all vulnerabilities is a time-consuming and difficult task. Moreover, many sites, notably social-networking ones, want to allow their users some leeway to create interesting content.

Mozilla’s CSP will break with Web browsers’ tradition of treating all scripts the same way. Instead, it will require that participating websites put their scripts in separate files and explicitly state which domains are allowed to run the scripts.

An engineer at the Mozilla Foundation, Gervase Markham, championed the idea within the Firefox team and further developed the technology, and noted Web security researcher Jeremiah Grossman publicly called for adoption of the technique. Four years later, Mozilla has committed to implementing the technology.

The new Firefox security feature could help block another form of attack, known as clickjacking, which allows an attacker to trick a user into clicking an unsafe button–for example, initiating a bank transfer when she believes that she is sending an e-mail. However, clickjacking is a problem so pervasive that an opt-in model really doesn’t work, says Hansen.

Violet RFID Mirror…..adds life to the Objects…!!

What do you think is common between these pictures: The rabbit-dolls or perhaps something that looks like a fancy kitchen ware – a dish?

I am sure you are still wondering what is it that you are looking at? But it definitely looks interesting enough to find out, doesn’t it? It is interesting, impressive and great fun!

These are magical Violet Mirrors based on the RFID technology. RFID – stands for Radio-frequency identification. RFID can be applied to any object to use it as a tag, to be incorporated into any products to make them come alive. The RFID tag enables tracking the product through radio waves. In case you are wondering where this technology can be applied, then you should think of tracking and managing inventories at supermarkets, or any application of supply chain management in several enterprises.

If you understand the identification part of it, you would also immediately relate it to tracking, timing, scoring and implantation kind of usage. For example, an electronic toll collection booth would have an RFID tag put to its best use to improve efficiency in logging and tracking.

Other amusing uses that have been referred to is to use it as a learning package for youngsters, who can wave things in front of these RFID mirrors and understand the relation or usage of the same. For example, if you wave an umbrella in front of this magic mirror it would give you a weather forecast, or let you know when you took your last medication if you place your pills on it. It has to be connected to a computer to perform all these functions though.

The colorful RFID tags and stamps are slowly making place for their applications in our surroundings to make life more convenient, if it isn’t enough already. For now, inventory systems and identification are probably the best usage of this technology.

Quantum-Dot Lighting – A New age of LED lamps

Quant D

Product: Array lamp with Quantum Light optic

Company: Nexxus Lighting, QD Vision

Light-emitting diodes (LEDs) are highly efficient, but they can’t directly produce white light. Though a blue LED can be coated with a phosphor that alters some wavelengths to yield a whitish mix, the resulting light has a bluish cast, and some energy is wasted as heat in the process. A new LED lamp avoids this problem by using an optic coated with quantum dots–bits of semiconductor material a few nanometers in diameter. When excited by a light source, the dots radiate light in wavelengths that vary according to their sizes. The optic–coated with dots in specific sizes and ratios–appears orange when the light is off (left) but radiates white light when the underlying blue LED is on (right). The result: LED lamps that are 50 percent more efficient and produce better-quality white light.

Quant D 1

Because the Nexxus Lighting Array lamps with Quantum Light™ are compatible with a standard, screw-in Edison base, they can easily replace incandescent and halogen lamps in existing downlight fixtures. Just in the US, the DoE estimates, the number of down lights and track heads with Edison base lamp installations equal over 139 million in commercial applications and over 262 million in residential lighting applications. Both companies expect that commercial availability of their high efficiency lamps with high color quality will overcome a major barrier to LEDs and will accelerate the penetration of LEDs in the $4 billion U.S. lamp market. The potential impact on the environment could be significant, a full conversion to LEDs of existing downlights and trackheads in the US (approximately 10% of US fixtures) represents an annual savings of more than 35 billion KW hours (nearly $4 billion), which is the equivalent of nearly 6 power plants or more than 60 million barrels of oil per year.

Forget Youtube…Here comes Wikipedia with Videos….!!

The Wikimedia Foundation plans to launch an editable, video encyclopedia to complement its text-based online encyclopedia. Since its launch in 2001, Wikipedia has grown at an astounding rate, with about 65 million visits per month and thousands of volunteer contributors writing, adding to and editing thousands of articles every day. In a multimedia age, adding video hopes to take Wikipedia to a new level.

The aim is to revolutionize the existing site by allowing open-source video to be accessible to the general public. The company hopes to be ready for the launch in the next few months.

So how will it work? When Wikipedia contributors begin to edit an article, they will discover a new Add Media button, which will allow them to access an interface, select a video clip from three repositories, containing copyright-free material, and drag it into the article. No video-editing software is required. The video clip will then be embedded in the article and will appear to the viewer as a “clickable” video clip.

In the future, users may also be able to be import video content directly from the web, and the content may be able to be edited within or added to the Wikipedia website.

At first, the videos will be sourced from three repositories: the Internet Archive; Wikimedia Commons, which is maintained by the Wikimedia Foundation; and Metavid. The Metavid repository contains videos of Congressional hearings and speeches. Some of the videos include closed-captioning text. In the future, this text will serve as a tagging system and will assist Wikipedia users to search for particular words or phrases and then import a certain section of a speech into an article.

The project is being partly funded by the Mozilla Foundation, creators of the open-source Firefox browser, which insists that all video imported onto its pages be open-source. The Wikimedia Foundation hopes that video content providers will allow their material to be available in the public domain, motivated by the exposure Wikipedia offers.

The project will also involve the development of web tools to enable users to easily edit and transfer video content, without having to deal with file conversions.

Touch Sight

Touch Sight is a digital camera for visually impaired people. Easy to use, it includes a unique feature which records sound for three seconds after pressing the shutter button. The user can then use the sound as reference when reviewing and managing the photos. Touch Sight does not have an LCD but instead has a lightweight, flexible Braille display sheet which displays a 3D image by embossing the surface, allowing the user to touch the image. The sound file and picture document combine to become a touchable photo that is saved in the device and can be uploaded to share with others–and downloaded to other Touch Sight cameras.

Design: Samsung Design (China)

The SoundBulb

There are various lighting and/or sound products available in the market, but most of them are very direct and serves a particular task efficiently. SoundBulb is an outcome of a competitive product market research across a wide range of exciting lighting/sound products. This concept utilizes both lighting and sound into one product and the final design features a bulb like shaped speakers that can be enhance the décor of your household as well as increase the functionality. The combination brings together the sophistication, ambient and elegance of lighting and sound in order to form a product that tickles our sense more than a single way.

The SoundBulb acts as a wireless speaker and a lighting device simultaneously. The bulb utilizes LED lights for illumination and Bluetooth to stream audio from a compatible computer or gadget wirelessly. The volume is controlled by twisting the bulb’s outer ring, while the on/off switch for the wireless receiver is located on the other side. The wireless speakers are powered from the electric socket it’s plugged to.

Dyson Human Energy Harvesting Bracelet

Dyson Energy Bracelet is a gadget that uses Seebeck effect to harness energy and power your mobile phones for a few precious minutes more, when you desperately need it. Lemme explain a bit: The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa. This typically includes three separately identified effects, the Seebeck effect, the Peltier effect, and the Thomson effect. This is coz three different guys discovered it around the same time, however Peltier–Seebeck and Thomson effects are reversible and Joule heating is not.

The designers explain:

Thanks to the Seebeck effect, the temperature difference between the surface which touch the skin and the other which is in the ambient air allows to produce electricity that is stocked in a battery. When the user needs to recharge a mobile device, he plugs it into the Dyson Energy through a micro-USB port (universal connector imposed to constructors in 2012) and can have some additional minutes in use.

Firstly, we have tested the Peltier element in its most common use: i.e. the creation of heat and coldness on the same component (Seebeck effect), and we have noticed that there was electricity production. We have met an engineer who allowed us to evolve on our project while explaining us that there was not possible to plug the elements serially. Therefore, we chose to work with only one element. As a result of many calculations, we have validated this technology payoff regarding our concept. For instance, some hours are sufficient to power its cellphone for a dozen minutes of communication.
