Submission + - Ask Slashdot: What is the future of standing/walking workstations?

Submitted by secretrobotron
secretrobotron writes: As a developer who spends most of each day at the same desk in the same chair, I'm concerned about ergonomics and what I can do to keep my body from wasting away while I program. Some IT professionals have the relative luxury of being able to walk around on a headset, solving problems, installing equipment, etc.. My utopia (albeit a pretty low-bar) is a world in which technology exists to allow me to walk about as I program.

My question is, what's available? Are people working on mobile-programming in this way? Are there hybrid standing workstations which allow me to take advantage of pacing-enabled programming?

Submission + - Possible Issues With The Proof That P != NP

Submitted by Anonymous Coward
An anonymous reader writes: Slashdot reported an annoncement that Vinay Deolalikar, a Principal Research Scientist at HP Labs, claimed that he has a proof that P is not equal to NP. Dick Lipton, a Professor of Computer Science at Georgia Tech, analyzed the idea of the proof on his blog. In a recent post, he explain that there have been many serious comments raised about the proof. Here is a summary of the objections that need to be answered in any subsequent development.

I think this is the best advice/reasoning here. Until I own a home where having some sort of security system or deterrent is of any use, or even possible to install, insurance is the best option. After searching quickly, insurance companies offer insurance for all your things if they cost about a minimum of $30,000 for about $40/mo. I pay more for my cell phone. The only other element of importance that's worth stealing is the data on my machines which is backed up off-site already, and will soon be locally encrypted when I re-install Arch.

Submission + - DIY Home Security

Submitted by secretrobotron
secretrobotron writes: I'm a recent university graduate from a co-op system which has kept me on the move every other semester, so I've never really had a permanent place to live, and I've never had the opportunity (or the capital) to buy expensive things. Now that I'm working, those restrictions on my life are gone and I'm living in a apartment with things I don't want stolen. I would love to build a DIY home security system, but I don't even know where to start since Google searches reveal things like diysecurityforum.com, which help only to an extent for a curious newcomer. Has anybody out there successfully built a home security system on a budget? If so, where did you start?

Submission + - $25,000 question: Is this Turing machine universal

Submitted by Anonymous Coward
An anonymous reader writes: Stephen Wolfram, creator of Mathematica and author of A New Kind of Science, is offering a 25k prize to anyone who can prove or disprove his conjecture that a particular 2-state, 3-color Turing machine is universal. If true, it would be the simplest universal TM, and possibly simplest universal computational system — even simpler than rule 110. The announcement comes on the 5-year anniversary of the publication of NKS, where among other things Wolfram introduced the current reigning TM champion.
