Comment I do this to reset my kids "summer schedule" (Score 4, Interesting) 173

I've used 2-3 day backpacking trips to reset my clock for years. Typically, after moving for 10-15 miles in a day under the sun with 25-50lbs on my pack and then making camp, I'm ready for bed at sundown anyway. I actually have to force myself to stay up til 9 or 10pm. For the last few years, though, I've used this to reset my kids summer schedules. Typically by mid-August they're going to bed at 2-3am and getting up around 12-1pm each day. So the last week of summer for the last 3 years we've gone camping. Nothing special no grueling backpacking trips. Just camping at a campsite with tents and a fire and day hikes, etc. After a week of this they're on a sun-up to sun-down sleep schedule and ready for the new school year.

Comment Re:Ethopia Airlines has a 787 Dreamliner? (Score 1) 246

"2. Does American Airlines belong to the Unites States of America?" Um, obviously the answer is no. But it *was* founded in America by Americans. And yes, We Are The World was recorded 28 years ago. But last I checked, Ethopia is still listed as a 3rd world country. In fact, its #10 on the list. I'm just surprised that a third world country has a friggin' Dreamliner (well had one that is apparently its burning right now). Then again, I guess I should be even more surprised that my comment wasn't even modded up for being humorous, but your's was for being "insightful" yet lacking any insight.

True. This started as a technical solution with only one finance person present. We know we have evaluations to do, etc to figure it out. I figured why waste the time going into budget and P&L meetings and crap if there's some huge reason it won't pay off. From the majority of replies it sounds like we'll burn more electricity and make some money but likely earn less BC value than we'll spend in power. That will be the focus of our next meeting and investigation and determining if we move forward with this.

Well, that's the general idea we're trying to figure out. Obviously if the PC is idle it uses fewer resources. But at what point does ratcheting it up to 100% utilization for 8-12 hours become worthwhile? Sure, it will consume more electricity, but say the extra electricity is $0.10 per PC times 18K PC's is an electrical bill increase of $1800. So we would need to generate 24 bitcoins in that 8-12 hours to break even and more to make money. Granted, this is loosely rounded math, but that's what we're trying to figure out. Is it feasible now? Or do I need to wait til a BC is $200 versus $75? Of course the real money *could* be to the botnet guys as they can use the swarm to generate revenue without caring about the electrical costs.

So one thing I should throw out there we're already very, very green compared to many companies. We are positioned near a local river & lake for cooling needs and use a solar farm (no I don't work for Apple in NC). All building roofs are painted white, etc etc etc. All laptop users are required to run on battery power throughout the day until 20% and then they plug in. Compared to your average company on a grid, we're already about 60% green and our electrical bills now are about 75% lower than they were 5 years ago accounting for inflation and the market and other offsets and adjustments that bean counters like to do. Our goal is to shave off another 10% within 3 years EITHER by consuming fewer resources or by offsetting our costs (ie: making money that covers electrical costs) or both. Please add your comments to the main thread, not this one just wanted to throw this out there as some additional information.

Submission + - Ask Slashdot: Enterprise Bitcoin Mining for Go-Green Initiatives 1

Supp0rtLinux writes: "Bitcoins are currently trading in the +/-$75 range. I work for a very large organization. We have a fairly large HPC that is usually about 50% idle, as well as about 18K desktops on 4 campuses connected with dark fiber. All stay on 24x7 for after-hours AV scans (weekly) and backups (2-3x a week). All are leases that refresh every 2 years so all have fairly good CPU & RAM specs. As part of a go-green initiative a proposal has come up to use all the PCs for bitcoin in our own mining group; sort of like seti-at-home style, but with a real dollar value return to us. Additionally, we would setup a queue in our HPC that dedicates 30% to BC mining when in use and up to 99.5% when no other jobs are running. The thought is that all the PCs are on 24x7 anyway and consuming resources so why not allow them to be useful 24x7 as well and generate bitcoins which can then be sold to offset the electrical costs of the running equipment and/or possibly even make a little profit. The guy with the idea says its a no-lose situation as if the price of bitcoins drops to below a certain level and is no longer a financially viable option, we simply stop the mining process. I'm curious what the Slashdot community thinks of this? Is it viable? Would we generate enough revenue to cover our electrical costs even with CPUs running at 100% utilization all evening? Are there any security risks? Any thoughts on network impact? The concensus is that the proposal sounds good, but no one has enough info to make a knowledgeable decision either way. Thus I'd like to know what Slashdot user's think.

As a follow-up question and one that came up after the initial proposal, this entire idea has us wondering why the botnet/malware guys aren't doing this already? It would seem like a trivial task to take a botnet of hijacked PCs and have them do BC mining instead of spreading more malware and generate real revenue for the owner's of the botnets wouldn't it?"

Submission + - Cops can record us, but we can't record them (journalnow.com) 2

Supp0rtLinux writes: "There have multiple, recent cases of people filming the police in various cities and having their cameras confiscated, being harassed, and even being arrested. Recent court decisions have ruled in the people's favor allowing us to film police in public. Yet some cities have continued to harass people doing so. Yet in Greensboro, NC the police themselves will be recording all the people they come in contact with thanks to your tax dollars. The true irony here is that people recording police could actually be illegal in NC. Is this the ultimate double standard?"

Comment The next app that FB is going to clone & knock (Score 3, Interesting) 102

Half the items shown at CES will be vaporware. Most of the rest will come to market too late to be of any value. The only thing worth seeing are the good ideas that some new or small company has come up with that Zuckerberg, Apple, or some other company can clone or otherwise knock-off and then present as their own (as FB likes to do) or as some new thing no one has ever thought of before (Apple I'm looking at you). I just hope it doesn't scroll or have rounded corners.
