+ - Test Pilot Admits the F-35 Can't Dogfight->

schwit1 writes: A test pilot has some very, very bad news about the F-35 Joint Strike Fighter. The pricey new stealth jet can't turn or climb fast enough to hit an enemy plane during a dogfight or to dodge the enemy's own gunfire, the pilot reported following a day of mock air battles back in January.

And to add insult to injury, the JSF flier discovered he couldn't even comfortably move his head inside the radar-evading jet's cramped cockpit. "The helmet was too large for the space inside the canopy to adequately see behind the aircraft." That allowed the F-16 to sneak up on him.

The test pilot's report is the latest evidence of fundamental problems with the design of the F-35 — which, at a total program cost of more than a trillion dollars, is history's most expensive weapon.

Your tax dollars at work.

Comment: Re:Why Not Java? (Score 1) 126 126

When I took it in 2002, it was C++ at the time. I think they switched to Java a year or two later.

You're close. I took the AP test the last year it was C++. I was also taking Java with the same instructor, same room, the next period, so I kind of had the best and worst of both worlds. But the instructor was top notch and is regionally well known - I'm very sure he was the primary factor in nearly all of his AP students both passing the AP test and having a job in the industry. Those two classes got me through my first two years of college and put me in a unique position for learning low/high level languages ever since.

That was 2003 when even the standard library was not nearly as defined and the boost/twisted libraries were still in their infancy. 2004 was the first year the AP comp. sci test was in Java and, IIRC, it was Java 1.4 when it was still reasonably fresh. These days I use primary Java and stumble through a handful of dynamic languages on an every day basis, but C++ still holds a special place in my heart - it's a shame I can't realistically use it in our production code; I really miss it.

That wikipedia article is horrible.

You know the nice thing about Wikipedia? When you find poorly written or factually incorrect articles you can actually do something about it instead of just whining about it on an unrelated website.

The other nice thing about Wikipedia is that the original author can be notified via RSS/ATOM that someone has changed their factually incorrect page and they can revert it in moments. A lot of people whine about that on unrelated sites because they're done spending their own free time fighting over fiefdoms when they can say "screw it" and just not hire people that come to an interview armed with whatever they read on Wikipedia.

What I'm saying is, while your solution absolutely makes sense in theory, many have found it unsatisfactory in practice but the flip side is that it retains a positive value as a filter; for that we thank the people that insist on misinforming whomever believes that a wiki is an authoritative source.

Because I'm hard pressed to think of a single "product" (and since most of them are free betas that's debatable) which Google has never treated any differently. It's their service, you're just using it in whatever state they give it to you today.

You seem to be confused about their product. You are their product; the advertisers are their clients. That's the service they don't mess with. There's a reason that they don't understand why enterprise customers need Java in the browser or wish they'd stop crying wolf on every SSL cert - selling services to a business isn't their model or one that they really want.

Probably because those customer would say "we need Java to access SuperMicro's IPMI interface on our internal networks. That's the same reason we don't want to click three times every time we use a self-signed/vendor signed cert or a cert that uses older crypto. We're on our internal network. Stop breaking stuff for no reason and fix the outstanding bugs we have open."

+ - Is our universe ringing like a crystal glass?->

TaleSlinger writes: Two physicists at the University of Southern Mississippi – Lawrence Mead and Harry Ringermacher – announced that our universe might not only be expanding outward from the Big Bang, but also oscillating or “ringing” at the same time. The Astronomical Journal published their paper on this topic in April.

As many know, scientists today believe our universe – all space, time and matter – began with the Big Bang some 13 billion years ago. Since then, the universe has been expanding to the size it is today. Yet, the universe as a whole has self-gravity, which tries to pull all the matter – all the stars, gas, galaxies, and mysterious dark matter – back together. This internal gravitational pull slows down the universe’s expansion. Mead said in a statement from Southern Miss:

The new finding suggests that the universe has slowed down and speeded up, not just once, but 7 times in the last 13.8 billion years, on average emulating dark matter in the process.

The ringing has been decaying and is now very small – much like striking a crystal glass and hearing it ring down.

+ - Does Windows slow down Windows?

blackest_k writes: I recently reinstalled windows7 home on a laptop a factory restore minus the shovel ware did all the windows updates and it was reasonably snappy. 4 weeks later its running like a slug and now 34 more updates to install. The system is clear of malware there are very few additional programs other than chrome browser.

It appears that windows slows down windows! Has anyone benchmarked windows7 as installed and then again as updated? Even better has anybody identified any windows update that put the slug into sluggish?

RoccamOccam writes: According to new information from the House Oversight Committee, the IRS deleted hundreds of backup tapes containing thousands of emails belonging to former IRS official Lois Lerner, the woman at the center of the conservative-targeting scandal. The tapes were destroyed nine months after a congressional subpoena was issued to the agency demanding they be preserved and turned over.

+ - Interview: Ask Linus Torvalds a Question

samzenpus writes: Linus Torvalds, the man behind the development of the Linux kernel, needs no introduction to Slashdot readers. Recently, we talked about his opinion on C++, and he talked about the future of Linux when he's gone. It's been a while since we sat down with Linus to ask him questions, so he's agreed to do it again and answer any you may have. Ask as many questions as you'd like, but please keep them to one per post.

+ - Recycling is Dying 1 1 writes: Aaron C. Davis writes in the Washington Post that recycling, once a profitable business for cities and private employers alike, has become a money-sucking enterprise. Almost every recycling facility in the country is running in the red and recyclers say that more than 2,000 municipalities are paying to dispose of their recyclables instead of the other way around. “If people feel that recycling is important — and I think they do, increasingly — then we are talking about a nationwide crisis,” says David Steiner, chief executive of Waste Management, the nation’s largest recycler.

The problem with recylcing is that a storm of falling oil prices, a strong dollar and a weakened economy in China have sent prices for American recyclables plummeting worldwide. Trying to encourage conservation, progressive lawmakers and environmentalists have made matters worse. By pushing to increase recycling rates with bigger and bigger bins — while demanding almost no sorting by consumers — the recycling stream has become increasingly polluted and less valuable, imperiling the economics of the whole system. “We kind of got everyone thinking that recycling was free,” says Bill Moore. “It’s never really been free, and in fact, it’s getting more expensive.”

One big problem is that China doesn't want to buy our garbage anymore. In the past China had sent so many consumer goods to the United States that all the shipping containers were coming back empty. So US companies began stuffing the return-trip containers with recycled cardboard boxes, waste paper and other scrap. China could, in turn, harvest the raw materials. Everyone won. But China has launched "Operation Green Fence" — a policy to prohibit the import of unwashed post-consumer plastics and other "contaminated" waste shipments. In China, containerboard, a common packaging product from recycled American paper, is trading at just over $400 a metric ton, down from nearly $1,000 in 2010. China also needs less recycled newsprint; the last paper mill in Shanghai closed this year. "If the materials we are exporting are so contaminated that they are being rejected by those we sell to," says Valerie Androutsopoulos, "maybe it’s time to take another look at dual stream recycling."

+ - Fintech - the oft forgotten tech sector->

Taco Cowboy writes: Goldman Sachs has over 9,000 engineers and programmers in its employment list — and the figure is higher than Facebook, Twitter or Linkedin

Massive amount of money is pouring into fintech. In 2014, global investment in financial technology startups spiked to more than $12 billion. That’s three times what it was just a year prior, according to Accenture. There have also been some huge funding wins this year. Most recently, zero-commissions trading app Robinhood announced $50 million round and financial education site NerdWallet attracted $64 million in funds

A booming fintech industry is incubating surrounding exchanges, hedge funds, banks and proprietary trading firms. But startups developing technology for trading and “markets” has been overshadowed by its consumer finance counterpart. They shouldn’t be

To demonstrate the opportunity in this space, the industry was recently the highlight of a sold-out, half-day event in Chicago. What was abundantly clear is that the trends that dominate technology – big data and networking, social media and app ecosystems – also dominate fintech startups

That’s because while other industries embrace the “fail fast” mentality, in financial markets and trading, fail fast thrives. The ROI of new innovations is often instantly quantifiable. When Anova Technologies built a laser and microwave infrastructure to carry data over airwaves between Chicago and Aurora, they knew the value of faster data – and so did all the trading firms that relied on being faster than everyone else. Once Anova demonstrated it could send data milliseconds faster, any firm whose competitive edge was speed had to subscribe

Other startups mine social networks to monitor for fast-breaking news from market influencers. Of the millions of people tweeting about stocks, Social Market Analytics identified a universe of 55,000 influencers, offering its tools to hedge funds and institutions to gauge market sentiment on which to base algorithmic trades

And then there are companies that are capitalizing on the app ecosystem. OptionsCity Software has launched a platform that is akin to the App Store for the trading world, where third-party developers or trading firms can sell risk management, pricing or analysis tools that plug directly into the trading system

This area is so ripe that the CME Group launched its own venture capital arm last year, Liquidity Ventures I LLC, to invest $500,000 to $5 million in startups that could help it develop new lines of business. Spanish bank BBVA, Fidelity and Bank of America have all created venture arms for increased investment in technology

Another reason to look at institutional fintech is that it proves its value very quickly whereas the jury is still out on consumer fintech, which has not yet seen tough times. Robinhood and Wealthfront have exploded, but so too have equity markets. If these consumer-focused companies existed in 2008 and 2009, would they have survived the massive exodus when consumers fled equity markets? How will they perform during the next bear market? At best, the answer is unclear

Financial markets are active, and banks, hedge funds and traders will need to make money no matter where the S&P 500 trades. Fintech startups in the trading space are still open to disruption, but aren’t subject to individual investors’ emotions. For that reason, this sector deserves closer attention

+ - The unintended consequences of Free Windows 10 for everyone->

Ammalgam writes: Microsoft seems to be really driven to pushing over a billion people to the new Windows 10 platform as soon as humanly possible. In the latest push to make this happen, the company has basically decided that (somewhat off the record), pirates can come in the side door and it really doesn’t matter what the state of their Windows license is, they can get Windows 10 for free. To get deep into the weeds on how this is happening, you have to read Ed Bott’s excellent article on ZDNET – “With a nod and a wink, Microsoft gives away Windows 10 to anyone who asks”. However, on, Onuora Amobi asks whether the cost benefit analysis has been done and if this deluge of new members will have a detrimental effect on the Windows Insider Program.

theodp writes: Last December, tech billionaire-backed teamed with Disney to teach President Obama to code, perhaps the capstone event of a Microsoft wished-for national K-12 CS and tech immigration "crisis". Just six months later, a NY Times report that Disney was making laid-off U.S. tech workers train their foreign H-1B replacements went viral, prompting journalist N.J. Connolly to tweet the news to CEO Hadi Partovi. "Were those CS majors or IT staff?," Partovi responded. "H1Bs in CS rarely displace." Partovi, like Lars Dalgaard and Joe Green, is also a supporter of (a 'Major Contributor'), Mark Zuckerberg's H-1B visa-seeking PAC. has in the past tweeted its dismay (img) at the idea of an H-1B visa cap.
