If "poor nations" is really your target market, you've got a problem. Why not make "Microsoft Vista / Homeless People Edition" as well, genius?

What your Sleeping position says about you


I think Marquardt's original paper appeared in a SIAM (Society for Industrial and Applied Mathematics) Journal somewhere around 1975.

As I recall:

Basically this is a compromise between steepest descent (very slow convergence, but converges from anywhere) and Newton's method (very fast convergence, but converges only close to the optimum). Newton's method also has the disadvantage of requiring computation of the Hessian matrix (the second derivative with respect to all pairs of variables x_i, x_j), or actually it's inverse. This is a very expensive computation.

The Newton direction is often not the same direction as the steepest descent. Levenberg-Marquardt attempts to use Newton (or perhaps a variant of Newton, using a positive definite approximation to the Hessian) wherever it gives good descent results, and steepest descent where it doesn't. There is a parameter which causes the update direction to vary between the two directions, and which also controls step size. The algorithm continuously varies this parameter to maintain descent as speedy as possible while ensuring that the steps are indeed descents.

I don't like to code.

Summing up: programmers don’t like to code, we like to solve problems. Coding is not problem solving, but software problem solving usually involves some coding. Even when we talk about rewriting something, the objective is not to code, it’s usually to get a better understanding of the problem for solving in the best possible manner.

So the French like open source software as well as Jerry Lewis

The sticks will probably contain the Firefox 2 Web browser, Thunderbird e-mail client, an office productivity suite such as 2, an audio and video player, and software for instant messaging, he said.

Netgear's Storage Central Turbo

Toigo, who has been testing the new Zetera-enabled NETGEAR box for the past month, said that the technology is "utter simplicity to deploy and use" and "performs with greater alacrity" than any of the low-end NAS products. "It is the perfect compliment to media servers and MP3 players for the consumer market in its current manifestation," Toigo said, "but I expect to see Zetera technology and architecture climbing the storage food chain in the near future to meet the business needs of millions of companies." - Daily California Technology News
