Submission + - Why sharks are almost impossible to outswim (sciencemag.org)

Pierre Bezukhov writes: Researchers have discovered what makes the shark almost impossible to outswim. By using an engineering imaging technique, researchers have discovered that as a shark’s tail swings from side to side, it creates twice as many jets of water as other fishes’ tails, smoothing out the thrust and likely making swimming more efficient. Sharks do this by stiffening the tail midswing, a strategy that might one day be applied to underwater vehicles to improve their performance. Most other fish have tails that are essentially symmetrical from top to bottom.
Java

Submission + - Java Now the Most-Attacked Software (threatpost.com)

Trailrunner7 writes: Java has become virtually unavoidable in the last few years, and it's installed on hundreds of millions of PCs around the world. A huge number of those target installations are vulnerable versions of Java, and this fact has not escaped the attention of attackers, who have made the technology one of their favored targets. In fact, new data from Microsoft shows that Java exploits were the most prevalent in the first six months of 2011, and that attackers often use exploits for bugs that are several months or years old.

Microsoft's research found that, having spent the time and effort to develop (or buy/steal) an exploit for a specific Java bug, they will continue to use it for as long as it's effective. Not surprisingly, the attackers don't seem to be having a difficult time finding PCs with vulnerable versions of Java to exploit. Although Java has been a frequent target for years now, users don't seem to be doing so well on the updating and patching front.

Chrome

Submission + - Chrome Overtakes Firefox in Browser Market Share (techcrunch.com)

SharkLaser writes: According to StatCounter, Chrome has now surpassed Firefox in market share and is now the second most used browser. Firefox is currently the only browser losing market share, as even IE's usage has recently grown, despite losing much of its share to Chrome last year. Globally IE now has 40.63 percent market share (50.66% in the US) and both Chrome and Firefox have around 25%. In related news, Firefox prepares to release Firefox 9 and currently Firefox 10 and Firefox 11 are in alpha stage.

I have to disagree with this. Currently, the two biggest cellular providers are Verizon and AT&T

Verizon was created from GTE + Bell Atlantic. AT&T is from Ameritech + NYNEX + Bell South + Pacific Telesis + SBC(changed name to AT&T).

Likely, only one of these entities would exist if AT&T continued to operate as a monopoly because I don't know if GTE had the clout to be as big as Verizon currently is by itself because moving cellular traffic depends mainly on access to fiber (T1s in days of yore). Which would mean that we would all have one technology for cell phones, with one option for a carrier. The other thing that came from the breakup, the Baby Bells had two work with each other to ensure that their new broken up networks would switch traffic after moving forward with independent network upgrades, which gave way to for more open/non proprietary standards to be implemented in the telecom industry and working interconnected networks with multiple routes and diverse locations (TCP/IP networks/slow rise of the Internet, respectively).

Government

Submission + - Feds: Hackers not to blame for llinois Water Pump (go.com)

Subratik writes: Feds "said in a Tuesday statement that detailed analysis by DHS and the FBI found no evidence of a cyber intrusion or any malicious activity."

But hasn't a hacker already come forward with an 'official' Pastebin post?

It seems we will have to choose between whether we trust the government or trust the internet folk.

Facebook

Submission + - Google+ loses 60% of active users (theinquirer.net) 2

tech4 writes: Despite users curiosity around Google+, it seems like most Google+ users just wanted to see the platform and then returned to Facebook. 'Google has lost over 60 per cent of its active users on its social network Google+, according to a report by Chitika Insights, raising questions about how well it is doing against its rival, Facebook. Despite the clear interest in an alternative to Facebook, it does not appear that the people joining are staying around and actively using the web site. Google's problem is not getting users in the first place, it seems, but rather keeping them after they have arrived. For now it appears that a lot of users are merely curious about Google+, but return to the tried and tested format of Facebook when the lustre fades. The problem is that Facebook is not going to rest on its laurels while Google attempts to get the advantage. Already it has added features inspired by Google+, particularly in terms of improving the transparency of its privacy options.'

Submission + - NASA wants solar-powered spacecraft propulsion (networkworld.com)

coondoggie writes: "NASA today said it picked five companies to begin exploring the feasibility of using solar electric propulsion to power future spacecraft.
According to NASA, multiple studies have shown the advantages of using solar electric propulsion to transport heavy payloads from low Earth orbit to higher orbits. The idea would be that traditional chemical rockets could deliver payloads to low Earth orbit and solar electric propulsion could then power a spacecraft to higher energy orbits."

Submission + - Best Buy's Net Income Down 30% (wsj.com)

nauseum_dot writes: Best Buy has had decreased profit over the last year. It appears that its online strategy coupled with its Brick and Mortar stores is causing it to be no longer profitable. From the article "its signature stores are still struggling to adapt to the changes in the electronics market, and analysts worry many of them have become 'showrooms' for merchandise that consumers wind up purchasing online from competitors such as Amazon." Do you think Brick and Mortar can survive in the online only world? Without Best Buy, where can fellow Slashdotter's try it before they buy it?

Comment Re:Size is a marginal factor (Score 1) 897

I don't think most people are under a false belief that big cars are necessarily less fuel efficient. Math points out that they are correct in that assumption.

I am thinking back to something I learned in statics class... If a car gets bigger, it will have a greater distance between the supports, frame, etc. Therefore we need to account for that Force applied will be the same, but the magnitude of that moment will be higher, aka: M=Fd Therefore, an Engineer would have to account for that moment to meet safety standards and would do so by increasing the mass of the supports, frame, etc to counteract the moment. This in turn, makes a car inherently heavier.

Comment Maybe this makes cents? (Score 2) 488

Sounds like the content providers are starting to work as an oligopoly and extracting the maximum cash out of Netflix, either that or Netfix is starting to cash in on the growing customer base.

Another thought just popped into my head, and that might be that Netflix is trying to actively fracture their customer base to beat on their chest to the content providers that streaming or on demand content is the only means people will access media, or it could be that they are going to sell off the DVD distribution side and focus on the lower costs associated without having to warehouse, sort, ship, receive, and resort DVDs.

What?

Seriously, how does a person make the leap from either making the economic decision of, "If I buy this game, I will have to play it through and it has no resale value nor can I restart where I left off. If I don't buy this game I will have the $50 in my pocket to buy another game without those features" to "Screw this, I am now going to spend $50 on the game and use $400 of my time to learn C, become proficient, start spending $700 of my time to reverse engineering how the memory works in the console, and finally use another $800 of my time to break the encryption systems, etc. that store the key codes for the game status, etc."?

I don't think your scenario is reality for 99.999% of the game purchasing public, most people don't want to spend $1600 in their own time to become a hacker, just to break the encryption on a $50 game . I think the choice much simpler: Buy the game or don't buy the game based on the opportunity costs associated with not being able to resell or restart the game.
