I actually sorted a large stack of numbered papers using quicksort. I chose it because it seemed to work well in the case of slow to move/compare paper.
You pick the pivot, initially at random but with re-selections based on the knowledge of the total set. After that, you can step through the whole stack in a fairly automatic way, paper by paper, easily putting papers into the left/right stacks by just shifting them left and right. No slow paper by paper insertions or other checks. Just a paper by paper step through to divide the pile (hopefully) into two; lower-lower-greater-lower-greater-etc-etc
I repeated the operation on the sub-stacks until they were at about ~5-10 papers. At this point I'd like to say I insertion sorted, but really I just shuffled them into position. And at the end, once all substacks are sorted, you just place them on top of one another and you're done.
The biggest problem I had was moving the substacks around and finding space for them once their numbers started getting larger. I would consider this the biggest bottleneck in the method.
Overall the operation seemed to work well considering the additional difficulty of actually physically moving the paper around by hand. But if someone reckons there was a better method I for one would be interested in hearing it.
"Earlier this week, an engineer noticed a slight irregular “bowing” above the spillway gates near where cars can drive across the dam.
When divers finally took a look under water they found a 2-inch-wide crack that stretched for 65 feet along the base of one of the dam’s spillway piers...
The artilcle goes on to say
"Even if the dam doesn’t fail, the significance of the damage is likely to require extensive repairs and that, too, could impact the entire Columbia River system.
“All these dams coordinate to generate energy on a regional scope,” Stedwick said. “If Wanapum is impacted, that has impacts on dams up stream as well as below.”
Up stream dams would be required to handle more water, the lower Dams means just one (Priest rapids Dam); after that is the last free flowing section of the Columbia river. Daily walks along that section I've seen it deviate (higher or lower) by amazing amount of water; it can handle it.
On top of this situation you have a large group of people that would like that particular Dam removed as well as the one above and below it (think of the fish!) http://www.npr.org/2013/05/15/..., after Priest rapids dam (down stream from Wanapum Dam) is the Hanford Nuclear Reservation http://en.wikipedia.org/wiki/H... once the site for Plutonium production area. Either of which stand to get a lot of press from this.
Personally I'd like to give the engineer that noticed a slight irregular “bowing” and atta boy.
If you don't like Apple's energy policy, buy majority shares.
And/or recruit other shareholders to your opinion.
Which is what he tried to do. It's a testiment to the Apple shareholders that it didn't work. B-)
Surely energy policies are about creating a feel-good aspect to the brand. Plus if you learn something along the way by trying perhaps you can commercialize it and it takes you off on another wild ride, like the iPhone did.
Directors and officers of a corporation have a fiduciary duty to the stockholders to run the company in their interest.
This USUALLY means trying to maximize return on investment. But the sotckholders may want other things, in addition to or in place of, financial gain. When this is the case, the duty requires them to set their own target appropriately.
This is not uncommon: Think "green energy company" or "church" for two examples. The Bell Telephone company, started by Alexander G. out of his research into hearing aids, has always done work on assisting the hearing impaired. Hershey's, at the direction of its founder, is owned by a trust and 30% of its profits go to support a school for orphans.
One typical strategy is to "satisfice", rather than maximize, financial gain, while pursuing other interests. This produces a sound financial base for pursuing those interests. (i.e. Hershey's, churches, "green companies"...) Another is to do things that are win-win with respect to the business (i.e. Bell Telephone, doing things like designing phones to work well with hearing aids, make ringing sounds that are auddible to the partially deaf and light-flashing ringer devices, and otherwise making the phone system accessable to hearing impaired.)
As you point out, these approaches may also lead to financial benefits that typical businesses and business-school graduate executives miss in their pursuit of the short-term bottom line. Good will, new inventions, synergies, etc.
Another example: Hershey's, not constrained or incentivized by short-term bottom-line, doesn't use typical industrial-food ingredients such as corn syrup, or follow other food-processing fads. It sticks with basic, high quality, time-proven, ingredients and recipies. This produces a consistent product (which also forms the base for consumer recipies) and a loyal customer base. (No "New Coke" debacle or gradual deterioration of product quality over decades with this company.)
When I was working in retail about 5 years ago competitors of ours did the same. Our store name, their phone number.
That reminds me of why dial phones were invented.
Early telephone exchanges used an operator to connect all calls. You picked up the phone and this lit a lamp and sounded a buzzer at an operator's console in the central office. The operator pulgged a cable into a jac and talked to you, found out who you wanted to talk to, and plugged another cable into the other customer's jack (or a trunk to another operator) to hook you up. Similarly when you hung up, or (if the call needed some other modification and you "flashed" by flicking the hook switch).
Some businesses bribed unscrupulous operators to redirect their competitor's calls to them, stealiing some of their buiness (especially in high customer turnover businesses, where a large fraction of the calls were initial contacts.) There was much flap over this, of course.
One such customer - an undertaker - decided to attack this problem at its root. He also happened to be what we'd now call a hacker (in the "exceptionally competent technologist" sense). He developed the earliest version of a dial telephone system, and got one of the telephone companies serving his area to install it. Electromechanical stepper switches were not susceptable to bribery, problem solved.
Of course electromechanical stepper switches are also cheaper than even low-wage people. So dial systems caught on very quickly. You still needed operators for non-simple stuff, but a company handling the bulk of the calls mechanically needed far less of them, and when such service was available businesses switched over en masse.
Is this cell site actually intended to be connected back to the grid, or is it only for communication between phones connected to this one site?
Back to the grid. According to TFA:
Backhaul to Vodafone is through the Cobham Explorer 500 Broadband Global Area Network, with communications being encrypted through IPsec.
That's a satellite modem that sells for about three grand. A bit over 0.4 mbps of encrypted data plus voice.
I agree. And this is stupid.
From the summary:
So, why do many of us perceive Whole Foods and the Creation Museum so differently?
Maybe it is because the stuff the author finds objectionable is just a segment of the stuff available there? But the Creation Museum is 100% about creationism.
