Google's Bouncer For Android Shows Malware Apps the Door

Google's Bouncer For Android Shows Malware Apps the Door

By Kate Freeman, VIA:mashable.com.

Bouncer scanning software, developed by Google, is designed to search the Android market for software that could be malicious, the company announced Thursday on its blog.

With the success of Android this year, the company says it wants to protect its many users and their devices from harm.

"Device activations grew 250% year-on-year, and the total number of app downloads from Android Market topped 11 billion," Hiroshi Lockheimer, VP of engineering, wrote on the Google Mobile Blog. "As the platform continues to grow, we're focused on bringing you the best new features and innovations - including in security."

Bouncer will scan current and new applications, plus developer accounts. The blog post explained how the service will function.

"Here's how it works: once an application is uploaded, the service immediately starts analyzing it for known malware, spyware and trojans. It also looks for behaviors that indicate an application might be misbehaving, and compares it against previously analyzed apps to detect possible red flags. We actually run every application on Google's cloud infrastructure and simulate how it will run on an Android device to look for hidden, malicious behavior. We also analyze new developer accounts to help prevent malicious and repeat-offending developers from coming back."

Bouncer was tested in 2011 and comparing the first half of the year to the second, Google Mobile reported a 40% decrease in malicious downloads.

Google says from the beginning, Android was designed with security in mind. And, although a company can't prevent malware, it can control the amount of damage those threats can cause with a dynamic security plan.

Some of Android's core security features are:

Sandboxing: The Android platform uses a technique called "sandboxing" to put virtual walls between applications and other software on the device. So, if you download a malicious application, it can't access data on other parts of your phone and its potential harm is drastically limited.

Permissions: Android provides a permission system to help you understand the capabilities of the apps you install, and manage your own preferences. That way, if you see a game unnecessarily requests permission to send SMS, for example, you don't need to install it.

Malware removal: Android is designed to prevent malware from modifying the platform or hiding from you, so it can be easily removed if your device is affected. Android Market also has the capability of remotely removing malware from your phone or tablet, if required.

Google's long been fine-tuning its security features for its various products. Although in the past Google's products have clashed with that of other mobile service providers due to security concerns.

Devs, start your compilers: Peek offers free/cheap devices to hackers

BY MICHAEL CRIDE.

If there's one thing the Android development community can't resist, it's a cheap mod platform. The Nook Color and (eventually) the HP TouchPad both owe their legacies to budget-conscious Android users looking for something to mod. The latest platform for cheap hacking might just be the Peek, a single-function device built for SMS on the cheap. The company is going out of business, but The Verge reports that CEO Amol Sarva wants to give the thousands of unsold units to hackers, hoping that "maybe somebody can build something great". At least one member of the Reddit Android section has the idea of porting Android to the device - a familiar rallying cry.

For those who are unfamiliar with Peek: it's a small BlackBerry-style gadget that's built for text messaging and email, and nothing else. The single-purpose Peek was sold for less than $100 and used cheap service without contracts as a hook for those who needed to stay connected without the use of a phone. The hardware is pretty bare-bones, but includes a full QWERTY keyboard, GSM connection, side-mounted scroll wheel and 2.5-inch 320 x 240 display - not that much smaller than a lot of cheap Android phones, though it's unfortunately not touch-enabled. Peek worked with a variety of email services, including POP3, IMAP and Exchange.

Can any of the Peek devices run Android? It's hard to say. Getting the hardware itself to boot a different operating system wouldn't be that difficult, but according to the Wikipedia page, the Peek's processor is a mere 100mHz and the storage space is a measly 8 megabytes. It would be a challenge for even the most talented Android ROM developer to get Android to fit on the device, to say nothing of it running properly. The Peek has no expandable storage, so getting it to hold more data would require some hardware modifications. Still, if anyone can do it, Android modders can.

Android Fragmentation Not So Serious: Localytics

Android Fragmentation Not So Serious: Localytics

By: Clint Boulton, VIA:eweek.com.

Google's Android operating system is regularly blasted for fragmentation. It won't be mistaken for Apple iOS, but it might not be as bad as we originally thought.

Much of the negative conversation concerning Google's (NASDAQ:GOOG) Android platform is predicated on the fact that it's fragmented.

Specifically, the concern is that there too many operating system builds spanning Android 2.0 to Android 4.0, too many devices and handset makers clogging an already crowded mobile market.

While it's not common to hear Average Joe Consumer complain about having too much choice, or even the occasional broken app that works on one OS build but not the other, mobile app developers have expressed concern about their ability to write for the platform and make money.

Yet Localytics in January collected data that shows developers shouldn't be as concerned as we all thought. The mobile analytics specialist said Android devices using applications with its analytics software have many specifications in common.

For one, 73 percent of Android handsets tracked by Localytics run Android 2.3 "Gingerbread," the penultimate platform. That number should shift as more users buy phones based on the latest Android 4.0 "Ice Cream Sandwich" operating system. We certainly saw this trend when Android 2.2 "Froyo," the OS leader for a good part of 2010, gave way to Gingerbread. And yet, 23 percent of user sessions are still running Froyo.

"Between the two, Android developers can be confident that they only need to actively target two Android OS builds in order to achieve 96 percent compatibility with the Android ecosystem,"Localytics concluded in a Feb. 1 blog post about its results.

To address the concern that Android developers should be concerned about writing code to fit varying screen sizes and resolutions, Localytics said 41 percent of all app sessions came from Android devices with 4.3 inch screens, which include the Motorola Droid X lines, as well as the HTC Thunderbolt and Samsung Droid Charge.

Next up were 4-inch screens at 22 percent. These models include the original Motorola Atrix and Samsung Galaxy S line. Also, 800 x 480 pixels accounted for 62 percent of resolution specs, per app sessions.

"For both screen size and resolution, Android developers have more to deal with than iOS developers, thanks to Apple's single handset form factor," Localytics noted. "However, with five options accounting for more than 90% of all Android app usage, the fragmentation is not particularly daunting.

Moreover, the analytics firm said Android tablets showed similar patterns, with nearly three quarters of all Android tablet usage from devices with the same specs, including the popular Amazon (NASDAQ:AMZN) Kindle Fire, Barnes and Noble's Nook e-reader and Samsung Galaxy Tab. Most of the Android tablets run either Gingerbread (71 percent), or "Honeycomb" (21 percent).

Localytics' point is that while fragmentation exists in Android where it may not for iOS development, it's not as serious as people have made it out to be. Perhaps this is true, and Ice Cream Sandwich will help fuse the fork Google created by splitting smartphone and tablets into two distinct branches a year ago this month.

But it still doesn't ameliorate the fact the handset OEMs and carriers decide what OS version goes on their handsets and tablets and that app developers have to write several versions of their app to work on different devices.

Worse is that OEMs and carriers withhold OS upgrades when they're available. While it's understandable that carriers and OEMs wait to push out OS upgrades until they've been properly tested, it still can lead to awkward moments.

Such as when friends with Android phones made by different OEMs served by the same carrier realize one has a fresher OS build than the other.

Android, iOS win Q4 market share in U.S. from BlackBerry, Microsoft, Symbian

By Dan Seifert, VIA:mobileburn.com.

It has released its report on the mobile phone market in the U.S. for Q4 2011, and from the looks of things, Android and iOS were the winning OSes this quarter, at the expense of BlackBerry, Microsoft, and Symbian.

Android's market share increased by 2.5 percentage points, landing at 47.3 percent, while iOS grew by 2.2 points to 29.6 percent. RIM's BlackBerry platform fell 2.9 points to 16 percent, while Microsoft (including both the older Windows Mobile platform as well as Windows Phone) and Symbian fell 0.9 and 0.4 points, respectively.

Looking at overall mobile phone manufacturers, Apple was the only one to make forward progress in the U.S., as it increased its fourth-place market share 2.2 points to 12.4 percent. Samsung held flat at 25.3 percent, leading the market, while number 2 LG and number 3 Motorola lost 0.6 and 0.5 points, respectively. Fifth-place RIM's market share dropped 0.4 points to 6.7 percent.

It is interesting to see that despite Samsung's record holiday quarter, it was not able to increase its market share at all. Also interesting to note is that while Android has a commanding lead in the smartphone OS space and is continuing to grow, it is taking share from RIM, Microsoft, and Nokia's Symbian, but not from Apple.

Does iOS Crash More Than Android? A Data Dive

Does iOS Crash More Than Android? A Data Dive

By Tomio Geron, Forbes Staff, VIA:forbes.com.

Ever wonder why certain mobile apps you use crash so much?

It turns out there are many possible reasons. And it can vary particularly depending on whether you are using an Apple iOS device such as an iPhone or iPad, or an Android device.

One of the reasons for crashes is the proliferation of mobile operating systems on iOS and Android. As Apple and Google have released more new operating systems, each with multiple updates, app developers face more operating systems to test apps on. In data that mobile app monitoring startup Crittercism compiled for crashes between December 1 and 15, there were at least 23 different iOS operating systems that crashed and 33 Android operating systems that crashed. (See the graphs above.) Note that the graphs that separate out Android and iOS show these number of operating systems and the graph that combines both iOS and Android shows less¨C22 iOS and 17 Android.

The largest proportion of crashes from both iOS and Android platforms were on iOS 5.01 with 28.64% of overall crashes (in a normalized data set). That makes sense since iOS 5 was still relatively new at that time and many apps still need to work out the kinks with the new OS. But there are also older iOS versions that have a significant proportion of crashes. For example, iOS 4.2.10 had 12.64% of crashes, iOS 4.3.3 had 10.66% and iOS 4.1 had 8.24%. One other point that this made clear to me is that many people apparently take their time updating their iPhone software or never update it at all.

The data raises two main questions for me: why do these operating systems crash so much, and does iOS crash more than Android? On the first question of why apps crash, the reasons are many, says Crittercism CEO Andrew Levy. This can be due to hardware issues, such as the use of location or GPS services or cameras; it could be due to the Internet connection, that is, how a phone connects to 3G or WiFi, or that the device is not connected to the Internet at a certain moment, or that something happens during the switch between 3G and WiFi. There could also be issues with language support on certain devices. There can also be memory problems if an app uses too much memory.

Problems can also occur with third-party services that developers use in their apps, from analytics to advertising systems. For example, there were reports that Apple's iAds system gave some developers problems if they did not adhere to certain standards. "It can be a mix of both hardware and software issues that developers may or may not be responding to," Levy says.

In addition, developers also constantly create new updates to their apps to create new features or fix bugs. But again, people often don't update their apps¨Cjust as they don't update their operating system. (Android, unlike iOS, allows users to auto-update their apps, which can eliminate some of the problems.) So developers often test all previous versions of their apps with each version of the different operating systems. "The permutations go on forever," Levy says. "That's a large reason for creating our platform." Particularly with a new OS, developers have to test their app to make sure it still works on the new OS. Often they will seek to test their apps in a test environment, but often that isn't possible.

The Apple iOS operating system crashes accounted for more of the crashes in Crittercism's data than did Android-based phones, as mentioned above. In the pie graph "Crashes by OS Version Normalized" you can see that iOS accounted for close to three-fourths of the crashes, with Android making up the rest. But is that just because Crittercism has more iOS phones in its network? Crittercism parsed some data to answer that question.

Crittercism analyzed a total of more than 214 million app launches from November and December 2011 from apps that use its service (see graph at top of this article). There were about 3 times more app launches for iOS that Crittercism analyzed, about 162 million to 52 million. But the analysis examined crashes as a percentage of each app launch, so this data takes out the issue of there being more iOS than Android apps. In other words for each iOS app and each Android app how often percentage-wise do they crash?

In the top quartile of apps, Android apps crashed 0.15% of the time they launched, while top quartile iOS apps crashed 0.51% of the time. In the second quartile of apps, Android apps crashed 0.73% of the time and iOS apps crashed 1.47% of their launches. In the third quartile of apps, Android apps crashed 2.97% of the time, while iOS apps crashed 3.66% of the time.

So what does all this data mean? On a basic level, you can see that iOS apps crashed more than Android apps during this time period. But Crittercism's Levy cautions that this doesn't necessarily mean that overall iOS apps crash more than Android apps. That's because Apple had recently released a new version iOS 5 in October. Android's new Ice Cream Sandwich operating system (Android 4.0), meanwhile, had not been widely released on phones yet at the time of this study. "I expect as Ice Cream Sandwich just launched and the new Nexus S phone launched (during the study), we'll expect the same situation to occur (with Android) as what happened (with iOS)," Levy says.

Still, the data shows that apps on iOS did crash substantially more than Android apps. Anecdotally, I know that certain apps I use on my iPhone crash and they crash often. Will that change as Ice Cream Sandwich rolls out and as more developers improve on iOS 5? We'll see.

One other thing about the data: in the best apps, that is, the top quartile, the apps crashed much less than in the third quartile. Levy emphasized that that shows the difference that developers can make with their apps by analyzing the data and improving their apps. Splitting up the data by quartiles also removes apps with massive user bases that can skew the averages.

My own point: when you get to the top apps, Android's lower crash rate than iOS makes less of a difference because they are both well below 1%. However, there was a bigger difference between iOS and Android crashes in the top quartile of apps than in the third quartile. In other words, the best apps in Android crashed about one third as many times as the best iOS apps, while the second best quartile Android apps crashed about half as much as comparable iOS apps, and in the quartile, the difference between the two operatings systems was even less. So the very top Android apps are achieving a crash rate that, at least in this time period, the best iOS apps can't match. Why that is, I'm not entirely clear.

However, Android, it should be noted, allows developers to push updates faster than Apple. With Android developers can just send an update to its code, which can show up almost in real-time. But for iOS it can takes days or a week for an update to show up. That means there can be more crashes while those updates are waiting to happen. Whereas with Android, presumably if developers know there's a bug they can immediately fix it.

One final piece of interesting data from Crittercism: The performance of apps is not only different on various operating systems but also on different devices. About 74.41% of the iOS crashes Crittercism tracked were on the iPhone, 14.81% were on the iPod Touch, and 10.72% were on the iPad.

Crittercism, which is backed by Google Ventures, Kleiner Perkins Caufield & Byers, AngelPad, AOL Ventures, Opus Capital and Shasta Ventures, provides crash reporting to app developers. The company provides developers with a wide range of data besides the mobile device and operating system, including, for example, the length of time between when an app is loaded and when it crashes, or how a user is holding a phone¨Cportrait or landscape¨Cwhen it crashes. It can also help evaluate whether an app's own code has caused it to crash or whether a third party service SDK being used is causing the problem. This kind of data is important for helping developers plug all the holes in the landscape of operating systems. Clients using Crittercism include: Aston Martin Explore, Bullet Time and Hipster.

Protecting apps from crashes is not only important for app developers, who by definition live and die by the ability of their apps to work smoothly. Increasingly, many types of companies rely on apps to run their businesses, even if there isn't a large consumer user base using the apps. Banks have mobile apps that enable check deposits, sales people use apps in the field, and so on. "It's about protecting your brand," says Crittercism cofounder Rob Kwok. "More and more business-critical functions are moving to apps."

Crittercism is signing up a number of large customers to its platform as a result. The company has already ramped way up from the 214 million app launches that it monitored in this data from November and December. If you're hoping to end those annoying crashes on your phone or tablet, that should be welcome news.

Batteries, power station into a new energy vehicles part of the most investment value

Batteries, power station into a new energy vehicles part of the most investment value

In the new energy automotive industry, which area of the "cake" most? With the rise of new energy technologies, the internal combustion engine vehicle business in the era of glamorous cases are being replaced by another, many companies want to cross the original parts threshold, a manufacturer of a vehicle. Analysts believe that in terms of market increments, battery, motor and other component manufacturers to benefit the most, even more important is the manufacturer of these parts or the auto industry will change the existing pattern.

Industry experts said that in the era of the internal combustion engine, the value of complete vehicle enterprises, accounting for 25% car, 75% of the cost in parts and components suppliers. In the era of electric vehicles, a car nearly 90% of the manufacturing part of the cost will be spent on parts, much of it is that the car battery.

"The battery is new energy automotive industry chain the most important and most valuable part of an investment with conventional cars, the new energy automotive batteries determines the basic performance of the vehicle's driving performance." Hongyuan Securities analyst Wang Jing said .

Battery is the core of new energy vehicles, the most critical component, as predicted lithium-ion batteries will soon become a mainstream alternative to nickel-hydrogen batteries power batteries, lithium batteries power the new energy vehicles on the demand-pull focus to become the brightest organizations. Clearly, the lithium-ion battery, motor, electronic control and other electric vehicles, industrial chain related businesses will face even greater opportunities for development.

"Europe, the United States, Japan in the traditional engine cars have a large advantage, hybrid HEV in Japan has a large advantage, but a large number of patent applications in China in the two paths are difficult to exceed the foreign industry in China selected Plug-in Hybrid PHEV, EV electric line in line with the long-term development goals automobile industry, while China in the battery, motor, lithium, rare earth resources have a comparative advantage, favor long-term development of new energy vehicles. "CRE securities analysts Gregory believes that the basic power to determine the route of lithium battery positive.

"The new energy policy support for a larger car, its long-term development path has been clear, the market needs gradual cultivation, but may exceed the expected progress in the development of electric vehicles, batteries benefit from a larger variety in China has been more negative and the electrolyte mature, positive will gradually mature, now mainly in the settlement of mass stability problems. lithium is the general trend of long-term development. "CRE Securities expects the new energy vehicles in 2012 will exceed 10 million units, which 6 billion battery industry can lead the market in the next three annual compound growth of more than 50%.

Another forecast that the lithium battery is likely in the next 10 to 20 years to develop into a several hundred billion-dollar global market, and a few dominant companies will reap most of the growth of the industry results. Therefore, Huatai Securities analyst Yao Hongguang suggested the company's investment in this area should be "re-light price" principle, the quality of future competition in strategic emerging industries to win in a higher probability of return can bring potential growth , the valuation will be much higher than the increase in short-term high investment costs. Currently in development and production of lithium-based listed companies sailing shares, universal cash flows and the billion Wei Li, etc., to produce lithium-based components have Fosugufen, Topband shares Shanshangufen, China Fang Textile, China Baoan, Foshan lighting.

New energy vehicles will quickly pull the industry is supporting another power plant construction. Grid Corporation of the charging station construction has been in full swing, the national network planning and construction of 75 in 2010 electric car charging stations, more than 6,000 charging pile, with South network project will be completed by the end of the total over 100 charging stations. Great Wall Securities expects the State Grid Corporation of the capital city construction completed in 2015, charging stations built in 4000, to 2020 10 000 charging stations. Power Grid Company's strategy is to build the new energy vehicles into the grid system of distributed energy storage and energy use, improve electricity as a proportion of final energy consumption. Meanwhile, the infrastructure supporting the construction of the development of new energy vehicles in China has provided a guarantee.

Mobile phone battery conservation attention to two errors & four

Myth one: the time to charge more than 12 hours, repeated three times to activate the battery.

This statement is very wrong, the above argument is for the nickel battery, but the current mobile phone lithium batteries are used.

For over-charging and over-discharge of lithium batteries, especially lithium-ion battery fluid can cause great harm. Because the most appropriate charge in accordance with standard enrichment, and more than 12 hours to avoid the charge.

Myth: For the activation of mobile phone batteries.

Currently sold through the mobile phone battery manufacturers are activated through the battery, so no need to carry out the activation can be, will be adhered to over-discharge ion activity was reduced. Thus reducing the life.

Note a: not freeloaders use cottage battery.

First, be sure to choose to purchase a large manufacturer of genuine battery, try not to use non-original batteries, charger. When a problem is to have access to the battery to the battery manufacturers, repair and replacement.

Note 2: Do not charge too long.

Many of my friends are used to charge at night, wake up do not know how long the battery has been charged.

Battery as much as possible to avoid more than 12 hours of charging time. If the conditions allow it, the battery is fully charged when it should stop, according to the battery to avoid unnecessary damage.

Note three: mobile phone to do to empty before filling.

There are a lot of friends that completely dead battery to a rechargeable battery is better for this.

In actual fact, no electricity in the phone prompts when they should start charging.

It has been too low because the cell phone battery warning appears, still do not charge to use the example has been used in automatic shutdown. The results of this case, cell phone charging and starting later in the no response, had to send customer service overhaul. In fact, this is because of the battery due to excessive discharge leading to low voltage, so that does not have the normal charging and power-condition caused.

Note 4: Note waterproof.

Pay attention to moisture to prevent the battery drops to avoid the high temperature storage and charging, try not to call in the charge state, for a long time without the phone, take the battery out.

Secondly, the battery fell into the water encountered in the case, do not immediately shut down, do not press any key to chaos, This is to prevent water flowing into the gap with the keyboard circuit board. But should open the phone directly off the battery cover, and then erected the phone aside to let the water naturally. Let the phone dry naturally more secure, remember not to put sun exposure. Some phones will because prolonged use or damp surface bulge in the battery, the battery will blur the words the surface, this should not long uninterrupted time to call, to avoid the high-temperature environments, manufacturers try to help resolve genuine.

Toshiba, Mitsubishi, PSA cars with lithium batteries can challenge the durability

According to recent reports, Japan's Toshiba (Toshiba Corp.) Mitsubishi Motors will soon release an electric car battery supply system. And in addition to Mitsubishi, the Mitsubishi French partner - PSA Peugeot Citroen (PSA) is also possible to use Toshiba's R & D of lithium battery systems.

The news is issued, the Toshiba responded by saying: "Toshiba and Mitsubishi Motors began a year ago co-developing a vehicle called SCiB lithium battery system. The battery charging system with superior capacity, charging time is short and long life. "

Toshiba also said: "Since this lithium battery system has not passed the final test, so Mitsubishi has not yet officially decided whether to adopt this system, but Toshiba is hoping to become the Mitsubishi battery system supplier."

Followed by Mitsubishi Motors spokesman said, Mitsubishi and Toshiba does in the car battery exchange system. However, Toshiba, Mitsubishi refused to eventually become a lithium battery system supplier for comment. In addition to Toshiba, the Mitsubishi is still lithium battery systems with other vendors to contact.

BYD's secret front: iron battery will put into production

BYD's secret front: iron battery will put into production

The new plant was forced to arrest suspected illegal land use, delayed return of A shares, Hong Kong stock price is almost cut, fund holdings, Morgan Stanley lowered sales expectations and investment grade ... ... BYD (52.65,0.85,1.64%, the economy through real-time quotes) ( 01211.HK) recent troubles.

At the same time, BYD in its field of solar power and electric cars are still always high profile. Perhaps, in the individual this view, all the technical problems bothering the general will as he habitually overcome.

Compared with the above, BYD has been claiming that "nuclear weapons" iron battery will put into production perhaps it was really fun to do.

This is outside of the much-anticipated years of BYD's "core technology", and BYD committed to solar and other new energy into the layout, the secret is the concentration of forces BYD front.

However, the mystery is indeed mysterious, but also in the outside world into question. Has always been known for its low cost advantage, technical research capabilities, is really the same as in the field of rechargeable batteries to help continue its withering in the field of new energy to take the lead, will not like it's known as "the world's first production dual-mode electric vehicles "F3DM general, but no one saw the thunder down?

After all, this over the years to attract everyone's attention F3DM, has been listed since March this year, sold only 20 units, which with its full-year 1000 sales target far.

This is more than a year ago for its claim to a large-scale production of iron battery production plans cast a shadow. After all, BYD's secret front, whether it is iron battery, or solar cells, solar energy storage power plants, all based on large-scale electric vehicle based on sales.

BYD aware of this, perhaps after facing years of high-profile, it will eventually reach the outside world a glimpse of its secret nature to look at.

Expansion of new energy

"BYD is indeed the construction of a 100 MW solar cell production line, but has yet to reach capacity production line, also the commissioning phase." In mid-July, the PV industry, told the newspaper.

The source said, back in 2008, BYD claims to enter the photovoltaic field, and to institutional investors, said its part of the polysilicon used "physical laws" technology (a way to take high-temperature melting of silicon purification technology) - - "can reduce the cost per kilogram to $ 8."

Should the implementation of such costs would be subversive. In fact, until 2010, the most advanced silicon technology costs of $ 25-30 per kg. "BYD description of the 'low cost' solar energy prospects to our operation of the solar business is a listed company's investor relations bring trouble." The source said.

Until the end of the first half of 2010, BYD service delivery in the photovoltaic cell responses to 320 kilowatts of products. Guinea pigs is almost the size of a domestic plant size is also 20 MW.

Newspaper learned that the first battery company BYD signed the American Solar Energy Co., Ltd. (SolarPowerInc. Abbreviated SPI). SPI's main business of residential photovoltaic roof.

Shenzhen is a private, said they were not optimistic about the BYD uses "physical laws" manufacturing polysilicon. "Not only is their team, the technical action is not obvious, but in the United States, Japan, there have been several solar companies to do the physical law, later failed." Siemens is now relatively common (at high temperatures, take a chemical method of silicon purification technology), physical method, while a short process, low investment, low production costs, but the disadvantage is that the conversion rate instability, recession and rapid product and technology relatively immature.

For solar cell production status BYD, BYD, said: "Many aspects of solar energy plan, the company now are not made public, and not convenient to answer." BYD public relations, a person claimed that "solar production line is started, not very sure."

This does not prevent the vision described BYD. In the solar business, BYD has a very large project - a message from the Shaanxi Provincial Development and Reform Commission, Shaanxi BYD plans to build 5,000 megawatts of solar cell production line. It gave himself six years, to be completed by 2015.

In contrast, the domestic leading enterprises Suntech took eight years to reach the current size of 1,000 MW. This means that Suntech order to "catch up" BYD, have an annual production capacity by 50 percent, to 5,000 MW in 2015. Meanwhile, the annual PV market is also very expansion of the same magnitude.

As the world's largest market - the demand in Germany last year to 2,500 megawatts of photovoltaic cells.

Meanwhile, BYD's target, Suntech more than the "majestic" - to build the solar cell industry chain.

In addition to production, technology and market risks, the news from the Shaanxi Provincial Development and Reform Commission, BYD is expected to invest in the project, $ 22.5 billion is a circular economy industrial development in southern Shaanxi ten projects.

Funds come from, BYD did not give an explanation.

However, although no results of solar cells, but involved in the new energy industry, the success of the company in the capital market rally. In 2008, BYD began to spread on the market in the "low-cost polysilicon manufacturing" news. In 2009, BYD announced a solar cell project started in Shangluo City, the scale of 100 MW. In early 2010, came BYD want to build 5,000 MW scale.

The end of June this year, the news from BYD said, "a 100-megawatt production line will be formally put into operation, two 400 MW has started construction."

"'Will be formally put into operation' instructions not to do, that is, the same business and new energy vehicles, BYD is using the campaign ahead." Researchers said a brokerage.

Time difference

BYD is studied under in more new business, but called "nuclear weapons" - is still only iron battery technology. After all, in the company's territory, the main industry is still the car, and thus extended to other business.

BYD Fe battery is referred to as "nuclear." Lead outside the curious, this is a core technology itself exactly how powerful, can mass production?

The reporter field survey found that, until today, the iron battery production base in two projects are still construction sites.

This year, BYD shares soared up to 85 million.

In August last year, BYD announced electric vehicle battery production base in Huizhou, Guangdong capital construction, "can be large-scale production of iron battery." At that time the company introduced two projects are in construction in September 2008, and covers an area of 810,000 square meters. Phase II project that is BYD Fe battery production base.

One year, BYD electric vehicle battery production base status?

July 14, 2010, newspaper reporter based in Huizhou iron battery live to see - two project sites, the large tracts of land still loess overturned, dusty park, the site is basically a heterogeneous picture. And across the street from the park of a lively scene than here also do not see the hurry of the workers wearing BYD tooling.

In the two corner site, the reporter saw "BYD Battery Co., Ltd. Huizhou base two 1, 2 quarters," the project license. Start date of November 11, 2009, completion date is July 30, 2010.

Corner of the park, part of the blue roof of the plant has been built. According to the workers introduced into the plant has equipment. Reporters tried to enter the film factory, but blocked by security.

BYD Company Contact newspaper, responsible person, "the company has provided base-iron battery project is not currently open." A CCTV reporter said that CCTV has repeatedly requested access to iron battery production site visits, but the same was rejected.

Has been "secretive show people" BYD Fe battery production line, to start what will, quite a lot of speculation led to the outside world.

In April 2009, Huizhou BYD Battery Company, for electrical appliances, automatic washing lines and other equipment for a number of tender. In July, the Daya Bay District Government BYD two industrial parks located in the "BYD Auto paint production project environmental impact report" for the trial.

BYD various initiatives seems to indicate that iron battery production line, do the step by step. But so far, BYD Fe battery two sites, most of the wasteland.

There is speculation that "nuclear weapons" iron battery "carrier" - electric cars have not yet reached the scale of production, or constraints BYD Fe battery scale production of the main reasons.

December 15, 2008, BYD announced that its "world's first production dual-mode electric vehicle" F3DM listed. A year later, in March this year, an upgraded version of the car - "low-carbon version of" formally for personal sales.

Phase of product a year ago, "low-carbon version of" a piece of the roof to install solar panels. BYD said in addition to professional charging station and charge outside the home, F3DM low carbon version has added a third charge solar charge this way.

However, the number of sales months since, as by mid-July, the car sold a total of 20 units. One month of June, the only listed in the Shenzhen region of 12 units were sold.

This means that the electric car to be optimistic about the outside world until the mid-2010, BYD is still not sufficient to promote publicity in 2009 to achieve iron battery that mass production. BYD apparently aware of this, this, in addition to sales in Shenzhen enjoy subsidies, as well as in Shanghai and Hangzhou to promote F3DM and E6, the company is located in Changsha-based electric buses, but also within the year production.

Path

BYD along the way, voices of doubt and applause go hand in hand. Questioned for its main focus on: what to significantly reduce costs, iron battery and electric vehicle technology available why the delay?

"Advance publicity" is the key to external challenge BYD arrogant.

In the individual into the car business before the company is doing OEM rechargeable battery and cell phone parts.

In 2003, BYD acquired Qinchuan car, Wang is declared: "Do electric vehicles BYD entered the automotive industry in mind. BYD electric cars to do, is to make China's Three Gorges dam, the water turned into oil , so that all Chinese cities, the sky is as blue as in Tibet. "

In 2007, BYD entered the automotive industry is the fifth year, Wang has released rhetoric, issued a "Declaration of 2015 and 2025", respectively, for the "China first" and "the world's first" specific time. This year, BYD annual sales of only 85,000, car prices in the country also not on the number row.

In 2008, F3DM models listed, BYD became the national leader in electric vehicle technology. Although, the car was "shelved" until today yet to achieve mass production, but BYD "upstart electric car technology" image is already set.

Concrete expression of new energy vehicles and "electric vehicle technology upstart" status does not match. Until the end of 2009, 45 million units in the BYD car sales in total, the proportion of fuel cars accounted for almost all.

However, Wang's pursuit of electric vehicles, has successfully attracted the "Warren" Buffett's attention. Munger, Buffett's partner and even praised Wang, "This guy is simply a combination of Thomas Edison and Jack Welch." "Warren" shares, the BYD shares rising steadily to $ 80 or more.

The delays for F3DM for personal sales, BYD Auto Wang Jun, a spokesman said: They do not want in the market environment and facilities is not ripe harm the consumer market, BYD is willing to support national policy and other vehicles with lower prices make this market bigger.

BYD said that the current market environment and the facilities are not yet ripe, such as charging station, charging pile set and other facilities is not perfect, also involved in power system communication, and the Government's strong co-ordination.

Interestingly, in the "environment, immature," the constraints of, the BYD launched a more ambitious new plan - "to enter the field of solar cells." BYD hopes in electric car, and then attach the solar cells.

Vertical integration

BYD to build solar cell production line, to make up for electric cars "car environment", the company has a new plan.

May this year, BYD in the United States Los Angeles financial district, set up a "car batteries and solar business" headquarters. Chairman Wang said at the scene, "I want every family to spend solar panels," and claimed that the company's next goal is to "expand the U.S. market", and then, and then shift the focus to hybrid and electric-powered vehicle.

July 13, BYD new energy into the house. Teamed U.S. KBHome, green residential building in the United States. Allegedly, this set of residential solar energy technology, battery technology and LED lighting in a number of new energy technologies.

This may be BYD "expanding American market", and also indicates the future direction of BYD solar battery.

However, BYD This time together to create a new energy with only 5 residential units, and the use of new energy technologies, there is no commercial. In China, only used in BYD own "future village". "Future village" is BYD in Shenzhen, Ping Shan base two villas, the company's technology in this laboratory.

At the same time, BYD's under the IT field - rechargeable batteries, will be this year, further increasing battery product applications portfolio for the development of electric vehicles and energy storage power plants and other new business areas to prepare.

Portrayed to the outside company BYD new energy business is in addition to IT and vehicles, to enter the third area. New energy businesses including solar power stations, storage power stations, new energy vehicles, solar cells.

BYD said the company will use the "vertical integration" of low-cost model, transplanted to the new energy sector.

July 22, BYD insiders told this newspaper that "companies do business in preparation for home appliances," However, the source said, "executives explained many times in the meeting, disclosed this business is currently not allowed."

Can be expected that BYD appliance business should also become a part of the industrial chain.

In addition, the Shenzhen Municipal Government in seeking industrial inland after the transfer of Foxconn, BYD more support in the field of electric vehicles, BYD give great support. Its two electric vehicles F3DM and E6, respectively, for maximum 89,000 yuan and 129,000 yuan in subsidies.

According to this understanding, in order to support the BYD new energy vehicles, the local taxi company in the government specifically selected 40 5-star driver, driving 40 BYD new energy vehicles. Elements of these drivers can not pay the money, the monthly wages of 6,000 yuan.

Excellent environment due to BYD new energy car battery - every day, taxi drivers can only run 400 km. BYD new energy into the short battery charge, the charge and long charge. Among them, half-hour fast charge is 60% full, and long you need to charge full six hours. The actual experience of the Shenzhen taxi drivers, or BYD electric cars to bring new energy reputation.

In new business, apart from capacity expansion in mid-July, the Ministry instructed the Shaanxi Provincial Department of Homeland conjunction with the prosecution, and severely punish illegal land BYD shares Xi'an Plant incident cast a shadow over the business this year as BYD.

It is understood that in order to "shock 800 000" sales target, Xi'an BYD launched last year expansion project. Currently, the project was forced to run aground.

BYD existing capacity of 500,000 vehicles, of which the capacity of the facility with 300,000, but this year sales target of 80 million. According to data released by China Association of Automobile, BYD first half of 2010 sales of 28.5 million. After the incident, the industry worried that the company had sales of cold car will again increase.

For some time, BYD was Fidelity holdings, Morgan Stanley lowered sales expectations and investment rating, A-share listing of major UBS Securities Asia surgeon who also announced the departure of President Cai Hongping. July 14, BYD announced that plans to issue A shares of one-year extension, until September 7, 2011.

BYD has a whole lot of good new energy vision, however, these profits to support automotive business alone is not enough. As a "technology upstart" of BYD, how to promote new energy carrier, the outside world to be seen.

Central locking new real estate enterprises sacrifice energy?

Central level has always been the backbone of the Chinese economy and the backbone of every major action they will guide the next people's livelihood. March 18, the SASAC disclosure requirements in addition to 16 real estate industry of central enterprises, 78 non-real estate industry based central level, the completion of its own land development projects have been implemented and work to to exit the real estate business. Today, the central enterprises to make real estate delisting has passed more than in March, the central enterprises to withdraw from the capital to invest in real estate where, become a community focus.

July 20, the National Energy Board Planning Division, said Jiang Bing, have become a draft of the new energy industry development plan submitted to the State Department is preparing, which includes the nuclear, wind, solar, biomass, geothermal energy, unconventional natural gas and other new energy and renewable energy development and utilization of new energy industry planning in 2011 and 2020 the cumulative increase of 10 years, about 5 trillion yuan of investment.

In fact, the SAC have already arranged, Deputy Director Huang Danhua had repeatedly pointed out: "central enterprises to explore a variety of ways and means of the use of external innovation resources and create a good culture of innovation. The central enterprises to accelerate the clean-up and inefficient non-core business assets speed, and strive to achieve structural adjustment and industrial upgrading of the breakthrough. "

In fact, some central enterprises have also been some move to its investment strategy in emerging energy industry has been fully mobilize the enthusiasm. Earlier this year, China Shipbuilding Industry Group and China Huadian Corporation signed a strategic cooperation agreement in Beijing, both sides will wind power, new energy development, transmission and distribution equipment and other areas intensify cooperation; then, China and the China Shipbuilding Industry Corporation, and Huaneng Group signed a strategic cooperation agreement in the hydropower power (heat), deepen cooperation in new energy sources; National Grid closely follow the development trend of new energy cars, China's Sinopec is likely to become a pioneer in the promotion of new energy vehicles; SDIC Electric Power, Five central power generation enterprises, CNPC, CNOOC, COFCO Group and other central enterprises in the new field of energy has been conquering a city, and even military equipment, aerospace, aviation and other large state-owned enterprises have entered a new energy field.

The benefits from science and technology: China's PV curtain wall patented technology ascent

Statistics in Beijing Intellectual Property Office, the Chinese solar industry applicants, a man named Li patent ranked first of 40 patents. Who is Li? Later we learned that Li founded the company in Shenzhen City, the benefits from technology in solar technology has been quietly walking in front of the industry.

Manufacture of solar modules of raw materials into three categories: monocrystalline, polycrystalline and thin film amorphous silicon. Thin-film amorphous silicon due to low production costs and more low-carbon environment, is being more and more attention.

Thin-film amorphous silicon technology as an energy-saving technology, the industry as the second-generation solar cells. On the conversion efficiency of amorphous silicon thin-film deposition of different chemical properties through the material layers in different segments, the conversion efficiency by 6% to 12% or higher laboratory efficiency up to 17.8%; Secondly, the film absorption wider wavelength sunlight, weak sunlight on cloudy days or operate better; Third, the production of amorphous silicon thin-film energy payback period of just 1.5 years. But at present, polysilicon technology has been in the industry for many years, a higher market share, while the thin-film amorphous silicon technology was still a novelty, but also need to address the problem of supporting low-cost mass production.

Li created the patentee the benefits from Shenzhen Technology Co., Ltd. is the largest thin-film silicon solar cell manufacturers and solution providers.

In 1998, the benefits from science and technology in Shenzhen City, Futian District, established the first 5 MW of thin-film amorphous silicon components of artificial production line in 2008 an annual capacity of 45 MW, 145 MW annual capacity of 2009, ahead of the domestic industry. 2010 the benefits from technology are planning to build a new 100 MW thin-film amorphous silicon solar cell production line, and plan to achieve 1,000 MW in 2015 low-cost mass production of silicon-based thin film solar cells, solar energy materials research and development project to establish a national center and photovoltaic application of technology design centers, become energy independent intellectual property rights of the new strategic industry base. The benefits from the current silicon-based thin-film photovoltaic technology in the industry, ranked the first, sixth in the world.

The statistics show that China accounted for 39% of global production of PV modules, is the world's largest producer, but 99% of the products are exported overseas. Adhere to the benefits from technological innovation, is now a company with more than 100 patented production technology of photovoltaic solar energy companies own brands.

In 1995, the benefits from technology introduced low-light-type amorphous silicon solar cell technology project identified by the experts, was identified as high-tech projects and to fill the gap. In 2004, its "BIPV" project was included in the national Ministry of Science, "15" research programs, the "solar insulating glass" was included in the national Ministry of Construction, scientific research projects. Benefits of technology innovation, "inline amorphous silicon solar cells and manufacturing method" also won the prize of Chinese patent and Paris International Invention Patent Award.

Energy Agency, United Nations survey, building integrated solar PV will become a 21st century city building energy-efficient hot market. The benefits from technology "low-cost amorphous silicon BIPV curtain wall components' technology in 2009 was named the world's most renewable energy technologies investment value of the top ten leading" Blue Sky Award. " Collection of solar photovoltaic curtain wall and curtain wall technology, photovoltaic technology, solar integrated building technology represents the latest development.

Located in Shenzhen City Longgang Baolong Industrial Park, the benefits from solar energy industry Solar BIPV curtain wall is the benefits from using the patented product: solar photovoltaic louvres point through the laminated glass and laminated glass, solar photovoltaic, the total installed power of 50 kW power output of up to 45,000 kwh per year. All use of green energy industrial park design, covering solar power systems, photovoltaic glass curtain wall and other high-tech environmental protection technology, called the solar energy industry base in the country's largest green plants.

Li said the 2030 film solar cells, solar cells account for the overall share of 30%. With the rapid development of the global PV industry, silicon-based thin film solar cell technology has matured, photoelectric conversion efficiency and stability of the continuous improvement of the future will have even broader space for development.

Laptop battery maintenance and use of skills B

If the friends reached the battery standby time than the "official battery standard", then we can still be extended by a number of ways:

1,25 using a standard external environment, the use of lithium-ion batteries can reach the best condition, if the temperature is too high, not only the laptop itself runs slow or even crash, and the battery in such an environment is also under will affect its efficiency. So as far as possible under the indoor environment using a laptop.

2, the less frequently used equipment disabled. Usually the best use of battery power when the interface is no need to disable the swap, such as wireless network card, printer port, infrared port, 1394 Firewire, etc., or you'll waste a lot of battery power, the specific method is to "control panel "-" System "-" Hardware "-" Device Manager "to find they have to disable the device, and then click" Disable "on it, you need the time to be" enabled devices ", is very simple. After disabling the use of results have been very obvious, you can save a lot of power.

3, to reduce power consumption within the device. More and more CPU-frequency, high-speed hard drives will bring a lot of energy consumption, and increased heat dissipation. Therefore, no special requirements, the best use of the system or the internal or third-party software to control the drive speed, not to open too many windows and programs in order to avoid CPU overload of work, it will not only reduce battery power consumption, the other can reduce heat , in the "hot autumn" season there, this is still a bit of benefits.

D, start charging the laptop battery is very harmful

Start charging in the end there is no harm? I once saw a man turn my phone is charging, and then over that one: wow! How dare you start charging, you are not afraid to explode! ? Although it is a joke, but they reflect a lot of friends with errors. In the notebook, the previous design is that if some models now use battery-powered, so even if the plug in the AC adapter or battery-powered laptop, which is the "charge does not go" phenomenon, today's notebook computers are not so in the design of risk, and when plug AC adapter, when the external power supply immediately turned and began to charge the battery. So now there is no need to recharge off.

E, long-term casual aside without batteries

Users the problem is often ignored. But this is not a small issue, and I talk to the laptop engineer told the author, many notebook manufacturers to recommend that users control the battery power more than 5%, such an approach is to eliminate passivation of the electrode, because the laptop battery at the factory the time had already started to slow self-discharge (to activate the battery thing has been in the workshop is complete, we do not need to worry about), a laptop is likely to be consumers at the factory six months after purchase, and the battery has discharged six months the. Here again I suggest that if long-term friends who do not have the battery and AC adapter with power supply, it is best to leave the laptop battery 40% - 50% more than allowed to self-discharge power, without charge, then discharge the battery from it is easy to go wrong or even scrapped. You think, ah, self-discharge must be to release, but there is no power what you put it, ah, no problem strange!

There is also a need to pay attention to the question: if long-term battery-powered and not powered by AC adapter (for example students), put the battery in a cool dry place such as the cabinet. This approach is to avoid the humid environment, while if the whole do not, the best place to separate the battery and books, do not believe we bought the books when the attention of mobile phone and see, business is not separate from the battery and the machine placed?

F, crashed but there is no way to pull the battery

I have seen some friends before the machines will not shut down the phenomenon, even illegal shutdown do not work, Blame the great "fainted dead" system! Finally her brother directly to a second stamping a three to pull the battery with eyes closed, and heard to scream off the books. In fact, this practice is very harmful, because in the standby state, the memory is powered and working, if the rash take off the battery directly, missing data are inevitable, not in the plug when the AC adapter, battery check , such an approach can only be a hundred more harm than good.

10 recommendations for video editing

10 recommendations for video editing

Learning to use a video editing program can take time. Each program has its own peculiarities and secrets, but in any case, there are a few basic principles you should take into account whatever use program.

We present a list of 10 basic tips to help you improve when you start in the fascinating world of video editing.

1. What do you do? Prevention is always good

If you plan to edit the material you're recording, it's a good idea to turning your target and during recording. It is also advisable to get a scheme which is to be achieved.

It is important to find the variety combining different types of plane. One example is called action plans: If you're shooting a basketball game, a flag or take public if you can help in the assembly.

2. Organization and order, always

Put your name tapes and clips in an organized way to find the material more easily. It may seem obvious but when working with large amount of material is more than necessary. Another good idea is split long clips other shorter, will make your life much easier.

3. Formats

It is most appropriate to avoid problems is that all clips are in the same format. In case of mixed materials from various sources, photographs, text, etc. must always bear this in mind.

4. Riding is like solving a puzzle

The editor of Martin Scorsese once said that films begin in the assembly. Perhaps a statement somewhat excessive but it is true that the narrative possibilities in the editing are very broad.

Selection: Select the material is difficult but important. A shot in the dark is not see nothing will be practically useless (however good that you recorded).

Order: Play the order and time. If you've seen more than one movie you'll know that time is only relative.

5. You can always cut before

Do not be afraid to cut - not a sin Cut - Cut is necessary.

We're used to seeing movies and putting the pieces together "missing" for ourselves. An example: if you see that a child has fallen to the ground and in the next shot is in the hospital you know what happened in between. If you do not agree think that wedding video that seemed to have no end.

6. Sound

The music, dialogue, voice-overs ... The sound makes up a world apart. Going beyond superficial only going to remind you that a movie is more than moving image and sound that plays a role as important as the visual elements and, moreover, a good soundtrack can enhance a boring video, but there are always to use it to head.

7. Effects themselves, but as

As they say some editors, "If you feel sad, chain". A Bound is a transition between two planes in which one merges with the next. Although sometimes used as patches, the effects should be used to contribute something and not as arrangements.

It is normal to go crazy when you discover the many effects that exist but everything is good in proportion.

8. Text and graphics

The text and graphics are used continuously, especially on television. Also use them judiciously and in the case of text, make sure they are legible. About the subtitles, the key is in understanding that the viewer has time to read all the words.

9. Once edited, re-edit

Once you've finished the assembly, presents the results from beginning to end and decide what you want to change (because for sure you'll change something.) It is essential to view the video in its full duration, and recommended a second opinion.

10. Export your movie

You want to hang on Youtube or will you spend on a DVD to see it on TV? As you look you will have to choose one format or another.

How to format a USB memory

How to format a USB memory

USB flash drives, pen drives, USB keys, tokens or whatever they are called, are used as a briefcase, going from one place to another and keep all sorts of things: photos, text files, videos, music and more. It is very common for documents containing personal and general items that not everyone can see. So as soon as it is copied to the computer to delete the contents of the USB memory.

The deletion process is the same as that used for any file on your hard disk, but to make sure that the USB is actually deleted it is best to format.

Come into play format types. According to the operating system you're using USB or type in question will have to use one format or another.

For example, for Windows, you usually use FAT or NTFS, Macintosh HFS and HFS +, Linux ext2, ext3, etc. Also depends on the type of memory. Low-capacity disks use NTFS but not FAT. Anyway, let's deal with the more typical case is that of a USB memory detected by Windows.

The easiest is to select the external drive in My Computer and click on it with the right mouse button choosing the option drop-down menu format.

You'll see a window where you can change the name of the unit, check the memory capacity, choose the file system with which to format and the size of the unit and assignment. Should be left as the last two configurations are not to alter the memory compatibility.

If we want to ensure that formatting really delete files to make sure that there is no quick format selected. The last thing is to start. If the USB has a lot of capacity, the process can be lengthy.

Apple has patented 3D projection method

Apple has patented 3D projection method

Apple is a projection method for three-dimensional images has registered. The viewer must wear no glasses to see the 3D effect.

The U.S. Patent No. 7,843,449 describes how the pixels of the image on a reflective, textured surface can be projected. There, they radiate so that the left and the right eye of the beholder receive different signals, which produces the stereoscopic effect. The system also determines the location of the viewer, so that multiple people can view from different angles, the 3D projection.

The aim of the technology are now, according to the published patent description "affordable, on its own three-dimensional displays that give the viewer complete freedom of movement". It does away with different colored glasses, making it not necessary that the audience remain seated at a defined point.

Interestingly, one of the patent application for the drawbacks of existing 3D display techniques, including Parallel view and Holograms. Probably uses the same view Nintendo's next portable console 3DS. Because of the angle difference between the two eyes are each given pixel hidden, so, again, no glasses are necessary.

A hologram-like technology and share the other hand, 3D TV as the Toshiba one. To generate a two-dimensional image in real time, nine angle corrected versions that combine through the television projection to a 3D view. The spectators must remain in his seat but, like Apple criticized. Moreover, the method is extremely computationally expensive.

As with many new patents can also be derived from this is not soon appearing product. The request also comes from the year 2006.
