Demonoid torrent was shutdown last fall. For those who don't already know, Demonoid is back up. Looks like they found a new host for the Web site and the tracker is functioning properly as well. For those with old accounts, all the old data has been saved. It's almost as if they never left.

Demonoid is an invitation only community. You can only register by invitation. So, we are giving free invites to all our readers. Just add your comment and I will contact you. Hurry, there's no many invites left ;-)

Call them Web 2.0 sites or mashups — or come up with your own trendy term. Whatever you call them, there are sites popping up all over the Web that process information in new ways rather than just present it.

Some of them work with information you supply, letting you manipulate, track and share data, such as your schedule or your to-do list. Others, so-called mashups, draw data from different sites and reassemble it to make something new. They're all part of how the Web is evolving beyond just a bunch of point sources for information. Here are 11 examples that show what the new Web can do, from helping you organize your life to adding some personalized fun to it.

GrandCentral

You can use GrandCentral to sort and filter incoming calls and direct them to ring some or all (or none) of your phones.

Ever wish you could exercise the same control over incoming phone calls as you do over e-mail? GrandCentral — now a Google operation — gives you a new phone number and forwards incoming calls to any other number or numbers you specify. More...

Based in the Waitakeres, in West Auckland, software developer and artist Vik Olliver is part of a team developing an open-source, self-copying 3D printer. The RepRap (Replicating Rapid-prototyper) printer can replicate and update itself. It can print its own parts, including updates, says Olliver, who is one of the core members of the RepRap team.

The 3D printer works by building components up in layers of plastic, mainly polylactic acid (PLA), which is a bio-degradable polymer made from lactic acid. The technology already exists, but commercial machines are very expensive. They also can’t copy themselves, and they can’t be manipulated by users, says Olliver.

RepRap has a different idea. The team, which is spread over New Zealand, the UK and the US, develops and gives away the designs for its much cheaper machine, which also has self-copying capabilities. It wants to make the machine available to anybody — including small communities in the developing world, as well as people in the developed world, says Olliver. More...

Live coverage of the Google App Engine launch event is here.

Google isn’t just talking about hosting applications in the cloud any more. Tonight at 9pm PT they’re launching Google App Engine (Update: The site is live), an ambitious new project that offers a full-stack, hosted, automatically scalable web application platform. It consists of Python application servers, BigTable database access (anticipated here and here) and GFS data store services.

At first blush this is a full on competitor to the suite of web services offered by Amazon, including S3 (storage), EC2 (virtual servers) and SimpleDB (database).

Unlike Amazon Web Services’ loosely coupled architecture, which consists of several essentially independent services that can optionally be tied together by developers, Google’s architecture is more unified but less flexible. For example, it is possible with Amazon to use their storage service S3 independently of any other services, while with Google using their BigTable service will require writing and deploying a Python script to their app servers, one that creates a web-accessible interface to BigTable.

What this all means: Google App Engine is designed for developers who want to run their entire application stack, soup to nuts, on Google resources. Amazon, by contrast, offers more of an a la carte offering with which developers can pick and choose what resources they want to use.

Google Product Manager Tom Stocky described the new service to me in an interview today. Developers simply upload their Python code to Google, launch the application, and can monitor usage and other metrics via a multi-platform desktop application.

Coffee may cut the risk of dementia by blocking the damage cholesterol can inflict on the body, research suggests.

The drink has already been linked to a lower risk of Alzheimer's Disease, and a study by a US team for the Journal of Neuroinflammation may explain why. More...
