Submission + - Invention Make a Citibike Electric

An anonymous reader writes: Inventor Jeff Guida has come up with a way to turn any Citibike into an electric scooter. His ShareRoller is about the size of a small briefcase, weighs just seven pounds, and has a 12- to 20-mile range. From the article: '"Years ago, I would've needed a giant engineering company and several million dollars in development research and it still would've taken two years or more," Guida said. But 3D printing has changed all that. In the coming months, Guida hopes to design a universal bracket so that the ShareRoller can be used on any bike. He has some competition there, as there are a few companies that make wheels that convert regular bikes into electric bikes, but he says the ShareRoller is more convenient.'

Comment Helping severely limited people does not sell iPhs (Score 1) 348

"Our products are the best in aiding the blind" isn't about Apple products?

What is important is not what Tim Cook says. What is important is the result of what he says. Will talking about severely limited people cause customers to pay $550 for another (unlocked) iPhone, or pay a hidden increase of $550 for a new cell phone contract that includes a new iPhone? Will creating a distracting controversy cause customers to pay another $550? No.

We are witnessing the collapse of Apple. I once paid $1,500 for a laptop PC. Now far better laptops cost $500. Eventually people will decide that the smart phone they already have is enough.

Tim Cook is merely distracting people from thinking about the value a new iPhone has on the quality of their lives. The distractions do nothing about the collapse.

Comment Quicksort (Score 1) 195

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.

Submission + - Damming news from Washington State (seattletimes.com)

Trax3001BBS writes: Wanapum Dam has been found with a 65-foot (20 meter) crack. Water levels are being lowered to both reduce water pressure and give the inspectors access to the area.


"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.

Comment The real issue: Drawing attention to himself (Score -1) 348

In my opinion, that misses the point. Instead of selling the best qualities of Apple, Apple CEO Tim Cook made himself the object of controversy. That shows that he is not competent and should be demoted immediately. It also shows, in my opinion, that Apple is on the way down much faster than I would have guessed.

Former Apple CEO Steve Jobs drew attention to himself, but did it in a way that also drew attention to Apple products.

In my opinion, Steve Jobs was socially manipulative and self-destructive, but he had positive qualities, also. Tim Cook is merely self-destructive.

Comment Fiduciary duty to stockholders. (Score 4, Interesting) 348

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.)

Comment That's similar to why dial phones were invented. (Score 4, Interesting) 137

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.

Submission + - Tim Cook Advises Climate Change Deniers to Get Out of Apple Stock

Hugh Pickens DOT Com writes: Nick Statt reports at Cnet that at Apple's annual shareholder meeting Friday, Apple CEO Tim Cook shot down the suggestion from a conservative, Washington, DC-based think tank that Apple give up on environmental initiatives that don't contribute to the company's bottom line. The National Center for Public Policy Research (NCPPR), hasn't taken kindly to Apple's increasing reliance on green energy and said so in a statement issued to Apple ahead of the meeting. "We object to increased government control over company products and operations, and likewise mandatory environmental standards," said NCPPR General Counsel Justin Danhof demanding that the pledge be voted on at the meeting. "This is something [Apple] should be actively fighting, not preparing surrender." Cook responded that there are many things Apple does because they are right and just, and that a return on investment (ROI) was not the primary consideration on such issues. "When we work on making our devices accessible by the blind. I don't consider the bloody ROI," said Cook. "We do a lot of things for reasons besides profit motive, We want to leave the world better than we found it." Danhof's proposal was voted down and to any who found the company's environmental dedication either ideologically or economically distasteful, Cook advised "if you want me to do things only for ROI reasons, you should get out of this stock."

Submission + - Clap for the Wolfram: Language Demo is Insanely Great

theodp writes: The devil will be in the details, but if you were stoked about last November's announcement of the Wolfram programming language, you'll be pleased to know that a just-released dry-but-insanely-great demo delivered by Stephen Wolfram does not disappoint. Even if you're not in love with the syntax or are a FOSS devotee, you'll find it hard not to be impressed by Wolfram's 4-line solution to a traveling salesman tour of the capitals of Western Europe, 6-line camera-capture-to-image-manipulation demo, or 2-line web crawling and data visualization example. And that's just for starters. So, start your Raspberry Pi engines, kids — there is a lot more to programming than dragging-and-dropping Flappy Bird puzzle pieces!

Submission + - Open Source Initiative, Free Software Foundation unite against software patents (infoworld.com)

WebMink writes: In rare joint move, the OSI and FSF have joined with Eben Moglen's Software Freedom Law Center to file a U.S. Supreme Court briefing in the CLS vs Alice case. The brief asserts the basic arguments that processes are not patentable if they are implemented solely through computer software, and that the best test for whether a software-implemented invention is solely implemented through software is whether special apparatus or the transformation of matter have been presented as part of the claims (the "machine or transformation" test). They assert that finding software-only inventions unpatentable will not imperil the pace of software innovation, citing the overwhelming success of open source in the software industry as proof.
