You are quite correct that we have not built a single demo part. In the two years since I started talking about this project the following has happened:

1. Persuaded the Science Museum to digitize all of Babbage's plans and notebooks (this in itself was a non-trivial task involving a great deal of effort at all levels and they should be thanked for taking on the task).
2. Got the leading Babbage experts to join and work with me (Doron Swade who built the Difference Engine No. 2 and Tim Robinson)
3. Started a UK-based charity (again these things take time as there are legal requirements and the recruitment of a board of trustees)
4. Started research on the Babbage archive itself
5. Begun fund-raising.

No. 4 is non-trivial because there are literally thousands of pages of notes and > 230 large scale plans to decipher. Plus there's a hardware description language to work with. And the archive is not well documented. There are a number of different cross references that conflict with each other. I realize that all this stuff is boring and people would like to see an immediate result, but that's not going to happen. It's years of work to properly study this stuff and build a historically accurate machine.

Note that we have not proposed building the 1,000 memory location machine. That's far too much to demonstrate that it would work and would add to the cost and size. As for the number of parts, until we've deciphered all the plans and come up with a definitive plan that it's hard to answer but we believe there will be roughly 40,000 to 50,000 components to be made.

You are correct that I care about the PR side of things. I need to because I need to raise a substantial amount of money.

But it's far from all PR. There's now a registered British charity with a board of trustees and the pre-eminent Babbage expert, Doron Swade, who built the Difference Engine No. 2 at the Science Museum is running the technical side of the project.

Study of the digitized plans has been underway since February and some first results will be announced this summer. We actively want to build a 3D working model in a tool like Autodesk.

JohnGrahamCumming writes "Photoshop's clone tool provides a powerful way of covering up areas of an image. Uncovering those touched up areas can be done automatically using a recently published algorithm. This blog post describes the algorithm, with examples, and provides GPL licensed source code to image forgery detection."

By automatically forwarding from a range of ports all but one of which are honeypots and by changing the ports every minute only a user knowing a shared secret can determine the location of the real SSH server."

JohnGrahamCumming writes "My newly released Wildfire application brings social news to Facebook by exploiting Facebook's social graph. Instead of "digging" stories, or "voting up/down", stories gain credibility only if you deem them worthy of being passed onto your friends. Wildfire offers users three views of the news: the news you and your friends deem interesting, the news that the great unwashed deem interesting and a random view. Randomness means that the Wisdom of Crowds is harnessed without succumbing to mob rule. And RSS integration means you can automatically bring your feeds to Facebook and pass on a subset of the stories. Personally, I started with the Slashdot feed."
It's funny.  Laugh.

The problem with the average is that it hides a savage reality of Facebook applications: some have many users, most have almost none. 86% of applications on Facebook have less than 10,000 users, with 62% having less than 1,000."
