  StarCraft 2 lead designer Tim Morten recently in an interview, when asked whether there will be a Warcraft 4, StarCraft 3, when, he suggested that recent work might have, but that depends on the player's request.

  Tim Morten said Blizzard love real-time strategy, also hope to make more this type of game. Neither the StarCraft or Warcraft there are many stories that are not finished, but future content is to a large extent still is up to the player needs to decide.

  New development plan, the executives said no, because the team is still busy with StarCraft 2: development of the void left behind.

  Players increasingly fast food tastes these days, even confrontational, and strategic areas of strong RTS also was simple, ornamental, randomness prevails. In contrast, high barriers of Blizzard competitive RTS sentiment weakened is no way things after its games such as how to develop?

Conversation Meta CEO Meron Gribetz Hololens compared to Microsoft we have more

What is the ultimate form of wearable? Hello Kitty iPad Air

 

If you look at the way information is obtained, there is no doubt that the future King of the wearable device must be in your eyes. Specific to the digital 80% information from the eyes, 15% information from the ears, 5% information from others, such as touch, smell, and so on. So while in the field of science and technology the most visionary and creative companies Google has Google Glass away from the public eye, but there are still many startups in similar studies, such as Meta.

 

Meta Campus: geek heaven

"The big companies can't pack light. "In the Meta's Office, CEO of Meta Meron Gribetz said. "For example, Windows is Microsoft's burden. Windows interact represents the past, and the time for when you need a new way of interacting, small companies like ours have an advantage. "

 

Conversation Meta CEO Meron Gribetz: Hololens compared to Microsoft, we have more advantages

(For Meta headquarters perspective)

Meta based in Portola Valley, mountain, belonging to the edge of the Silicon Valley area. And VC is Stanford University gathered at the foot of the mountain Sand Hill Road, a beautiful environment, overlooking the panoramic view of the Bay area. Here was the world's biggest private tank collector Jacques Littlefield's estate, including a swimming pool, tennis court and a movie theater. Israel Army engaged in augmented reality technology research of Meron, this is without a doubt the best environment. "Before the Israel Army when we were working six days a week, working 55 hours a day, I paid only $ 200 a week, but I feel that this work is very exciting. So here, I will try to create the same environment. "

 

Conversation Meta CEO Meron Gribetz: Hololens compared to Microsoft, we have more advantages

(Tanks of the former warehouse, has become a Meta hardware lab)

Meron will be referred to here as "Meta Campus." And those using "Campus" to call their headquarters of young tech giants (such as Google, Facebook), META here into a can meet the needs of engineers a simple self-contained little Kingdom, where engineers can develop without distractions. Working hours every Sunday to Friday, most employees stayed here for more than 12 hours a day – which may be why Meron said, "an advantage" part, which like Microsoft used to nine-to-five big firms is unthinkable.

 

"This is a geek's paradise. "A staff member exposure knock on the table of the House code and we said. "Work and play here. "

 

More natural interaction Hello Kitty iPad Air 2 Case

Meta has two products: Meta 1 Developer version and version Meta Pro for consumers, which in September last year has already been shipped, which still further improvements, further progress is expected in the second half of the year will be disclosed. Meta's most amazing is that the combination of virtual reality and interactive, build a hologram, and through gestures, grabbing, clicks, zoom in and out, like Tony Stark in iron man (Tony Stark) show. In fact, the Meta is not only the iron man played by Robert Downey Jr doing endorsements, also brought in the iron man in the holographic interface designer Jayse Hansen designed Meta, Meta user interface will have some of iron man's shadow.

 

Conversation Meta CEO Meron Gribetz: Hololens compared to Microsoft, we have more advantages

(Entrance to the Meta iron man stills)

So, Microsoft Hololens compared with Meta and what's the difference? "Hololens wants to do in many places and similar to META, also through gestures, but only a finger is not indicative of future, Hololens pattern essentially is a Windows-based interactions, and interaction in the future must be a more natural way, your brain is your operating system. "

 

Meron further examples, such as Smartphones, iPhone innovation is a more natural way of interaction, two or three year old child can easily use. But even so, this set also features requires some learning, and Meta had to do was make this section more natural, even your grandma can master.

 

Meron's professional background is computer and Neural Sciences, throughout the interview, he also stressed this point. In his view, whether it be Google Glass, Hololens or other similar devices are mobile operating system portable to wearable devices, while META is hoping to go further, abandoning traditions before human-computer interaction, through a more natural way to interact with the brain, and gesture is just a lot of "more natural" interact with one another in one.

 

Meta can do?

In cinema modification "war room" where I put in and experience the Meta Pro. Meta Pro looks like a large pair of sunglasses, wearing "sunglasses", realistic stereoscopic 3D models and appears in front of the image, you can enter text, crawls through the gestures, blow up games in the asteroid, 360 degree rotation, a new car, to understand its internal structure, but an outsider you just point fingers.

Conversation Meta CEO Meron Gribetz: Hololens compared to Microsoft, we have more advantages

 (Meta "war room")

Of course Meta can do only this. As the first virtual reality and gesture interaction of smart devices, Meta is changing the way we communicate with data, and others will allow us to better communicate and collaborate, allow us to a better way to create, provide a more immersive entertainment experience ... ... Especially in industrial design, data visualization, medical applications, simulation and training, communications and games these verticals, Meta's strengths can be fully enlarged, but also by other application developers on Meta are concentrated in these areas.

Meta challenge

If Google places a small-screen Glass just in front of right, allow users to more easily obtain information relating to social, played only a "little Secretary" role of Meta is more imaginative, more emphasis on active and natural interaction in the creation of a virtual reality applications. To achieve this goal, Meta must complete solution from hardware to software, user experience, interactive identification, data collection and processing, and so on a series of questions, which further strengthen the commercialization of its complexity and degree of difficulty. While the areas of both AR and wearable, whether in technology as well as on the popularity, there is still a long way to go.

But from another perspective, representatives of Meta is the future direction of wearable display devices. Augmented reality in the future leader of the race, Meta has made a good start.

Unmanned aerial vehicles how quickly becomes famous Open source is behind Heroes

"Editor's note" no function is rapid proliferation is to a large extent thanks to the open source development of the flight control, plaguing the critical equipment for autopilot of unmanned aerial vehicle development. So, what is open source flight control? And how to develop it? This paper by two professors in the unmanned aerial vehicle design Institute of Beihang University wrote in robots, Lei feng edited excerpts of which part, share them with flight control technology and open source story.

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

Drone aircraft flying over the complex products, the four-rotor aircraft with its simple structure, easy to use, low cost and other advantages, first came into the public eye. However, this type of aircraft for flight control requirements are the highest, it stimulated the emergence of a large number of open source flight control based on MEMS sensor.

How to define open source

Open source (Open Source) first applied the concept of open source software and open source Foundation (Open Source Initiative) use it to describe those software source code can be used by the public, and the use of this software, modification and distribution are not subject to license restrictions.

Each open source projects have their own forum, managed by a team or individual, the forum regularly releases open-source code, and interested programmers can download the code and modify it, and then upload their results, managers from a large number of changes improve the program, and once again select the appropriate code in the new version. And so to form a "joint development and shared" a virtuous circle.

 

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

The development of open source software combined with hardware, open source hardware. Hardware and software differences between the physical resources should be committed to creating real goods.

Therefore, the production of open source hardware (OSHW) license under the heading (product) of people and companies have an obligation to clear the product is not in the original approval before production, sales and licensing, and does not use any of the original trademarks. Hardware-specific format of the source code can be used by other persons, in order to modify it. In parallel with the implementation of free and open source hardware design of hardware knowledge sharing and encourage open communication and trade.

Vans case

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

Open source hardware (OSHW) definition 1.0 is defined by the software based on the open source definition. The definition is by Bruce Perens as the Debian free software guidelines and Debian developers created.

Open source flight control is what?

Understand the concept of open source hardware, open source is easier to understand the concept of flight control. So-called open source flight control is based on automatic flight controls on the ideological basis for the open source project (Open Source Auto Pilot), containing both open source software and open source hardware and software control hardware is included in the firmware and the ground station software in two parts. Fans can not only participate in software research and development, can also participate in research and development of hardware, you can not only purchase hardware to develop software, also can make the hardware, which will allow more people to enjoy the results of project development.

Open source projects using commercial, so each open source control project will be given an official legal term to define developers and users ' rights, different flight control on the legal definition of open source is different.

Open source development of the flight control

Open source development of the flight control can be divided into three generations:

The first generation open source flight control system using Arduino or other similar open source electronics platform based, extended connection variety of MEMS sensors, unmanned aerial vehicle flew smoothly, and its main feature is a modular and scalable capacity.

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

Second generation open source flight control system with its own open source hardware, development environments and communities, using integrated hardware architecture, all 10DOF sensors, the master microcontroller, and even GPS devices such as fully integrated on a circuit board, to improve reliability.

It uses a three-axis digital MEMS sensor AHRS (IMU); can independently control aircraft en route, and can add the radio station to communicate with ground stations, initially with complete autopilot functions. This type of flight control can support wide variety of unmanned devices, including fixed-wing aircraft, rotary-wing aircraft, helicopters and vehicles, and have a variety of flight patterns, including flying manually, semi-autonomous flight and fully autonomous flight. Second generation flight control features high integration and high reliability, which is close to standard commercial autopilot.

Third-generation open source flight control system will be in software innovation and artificial intelligence. It joins the cluster fly, image recognition, autonomous obstacle avoidance, advanced flight capabilities such as automatic tracking flight, machine vision, clustering, development platform in the direction of the course.

You shouldn't miss the open source flight control legends

Arduino flight control

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

To talk about the open source development of the flight control from famous Arduino open source hardware projects to speak of.

Arduino is the first open source flight control, comprising Massimo Banzi, David Cuartielles, Tom Igoe, and Gianluca Martino, and David Mellis and Nicholas Zambetti in 2005 in Italy work interaction design Institute to develop together. Arduino company first developed for electronic enthusiasts to build a flexible open source hardware platforms and development environments, users can obtain from the Arduino website hardware design documentation, circuit boards and components to meet your design needs.

Arduino can the Arduino IDE and its supporting software to view the source code and upload your own code written, Arduino IDE uses the Arduino language is based on c and C++ language, is easy to grasp, and the Arduino IDE available in Windows, Macintosh OSX and Linux running on the three major operating systems.

As the platform is gradually being accepted by enthusiasts, features an endless stream of electronic expansion modules, MEMS sensor is one of the most complex is the integration of flight controllers. For better flight control design source, Arduino company decided to open its flight control source code, they opened the open source development of the flight control. Famous open source flight control WMC and APM are direct derivatives of the Arduino flight control, still using the Arduino development environment for development.

APM control

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

APM (ArduPilotMega) is a community in 2007 by DIY UAV (DIY Drones) introduction of fly control products, is now the most mature open source hardware projects. APM is based on the open source Arduino platform for multiple hardware improves, including accelerometers, gyroscopes and magnetometers combination inertial measurement unit (IMU). Because APM better customizability, APM's global spread quickly within the RC airplane enthusiast. Mission Planner through open source software, developers can configure APM settings, accept and display sensor data, use the Google map features such as automatic driving, but the Mission Planner only supports Windows operating system.

APM flight control has now become open source flight control maturity benchmarking to support rotary wing, fixed wing, helicopter and unmanned equipment such as unmanned vehicle. Multiple rotor, APM four, six or eight axis flight control supports a variety of products, and connect the external GPS sensor can be augmented later, and completed their own landing, autonomous flight, go home, fixed-height, location and other flight mode. APM can connect external Ultrasonic sensors and optical flow sensor, high in an indoor setting, and flyover.

The PX4 and PIXHawk

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

The PX4 is an open source hardware and software project (compliance with the BSD Protocol), intended for academics, hobby and industry groups to provide a low-cost, high-performance advanced autopilot.

This project stems from the Federal Polytechnic of Zurich University's computer vision geometry laboratory, automatic control of autonomous systems laboratory and the laboratory of PIXHawk project. PX4FMU autopilot module runs an efficient real-time operating system (RTOS), Nuttx provides a portable operating system interface (POSIX) type of environment. For example, printf (), pthreads, and/dev/ttyS1, and open (), write, and poll (), ioctl () and so on. Software you can use USB bootloader update.

PX4 MAVLink communications with ground stations, QGroundControl compatible ground stations and Mission Planner, all open source software with BSD agreement.

APM jointly by the 3DR group and the PX4 PIXHawk flight control was introduced in 2014, PX4 flight control upgrades, with the PX4 and APM two sets of firmware and the appropriate ground station software. The flight control is hardware specifications, the highest in the world, fly control products, but also amateur the hottest product in the hands. Vans cases

PIXHawk 168MHz operating frequency, and groundbreaking uses integrated hardware floating point arithmetic of core Cortex-M4 as the main control chip, built-in two sets of MEMS gyroscope and accelerometer sensors, complementary correction, built-in three-axis magnetic sensor and can add-a three-axis magnetic sensor and two GPS sensor can be prepared by one of the add-in, when a failure in the automatic switch.

Core based on its high speed operation and floating-point arithmetic, PIXHawk uses the most advanced algorithm for high, can only pressure altimeter aircraft height fixed at 1 metres or less. It supports almost all type of rotor, even including the three rotors and H4 irregular product structure. It has a variety of aircraft flight patterns to support autonomous route, key points around the mouse, guide, "FollowMe", on flights and other senior flight pattern, and are able to independently adjust parameter.

PIXHawk flight control open very well, hundreds of parameters were open to player adjustments, underlying pattern of simple fly after debugging. PIXHawk integrates a variety of map, fans can choose according to the situation on the ground.

OpenPilot and Taulabs

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

OpenPilot was launched in 2009 by the OpenPilot community of the autopilot project, aimed at providing the community with low cost but powerful stable of autopilot. The project consists of two components, including OpenPilot, autopilot and its support of the software. Among them, the autopilot firmware by c language, while the station is written in C++, and available in Windows, Macintosh OSX and Linux running on the three major operating systems.

OpenPilot is the biggest characteristic of the hardware architecture is very simple, since it now has many hardware designs will be able to see the difference. Official flight control hardware includes CC, CC3D, ATOM and the Revolution and the Revolution Nano etc, derived hardware includes a Sparky, Quanton, REVOMINI, etc, even directly using the STM32 development board extension of FlyingF3, FlyingF4, DescoveryF4, CC3D is 300mm wheelbase across machines and mini indoor RC airplane the preferred flight control, and DiscoveryF4 been studied extensively for lovers of flight control, Quanton has become the preferred hardware Taulabs. Vans case

Here we talk about Openpilot's most popular hardware CC3D.

This control board using only a 72MHz 32-bit STM32 MCU and MPU6000 will be able to complete the four-wing, fixed-wing and helicopter attitude control (note that the hardware is available three-freedom attitude control, rather than augmentation), PCB size of 35mmx35mm.

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

Different from all open source flight control, it does not require GPS integration or magnetic field sensor into the amendments, will be able to maintain attitude control for a long time. All the features above all use a firmware, can be changed by setting the aircraft type, flight mode, supports PTZ functions such as augmentation.

The compiled firmware required capacity of only about 100KB, code amazing efficiency, all flight control programmers learning model. Its ground station software is integrated with a complete map, or real-time status monitoring aircraft through the radio.

TauLabs flight control is the derivative of OpenPilot flight control. Current most popular hardware called Quanton TauLabs, the former OpenPilot flight control team members to complete.

It inherits the characteristics of OpenPilot is simple and efficient, and extend the barometric altimeter and tri-axial magnetic sensors, upgrading the master microcontroller to Cortex-M4 core with hardware floating point arithmetic. The flight control is the first open source flight control supports automatic scheduling products, with model identification algorithm in flight attitude PID control parameters self-tuning. TauLabs can complete many advanced flying mode, connect an external GPS can make the rotors have set higher, location, home and other functions. Flight control is integrated with the map, and the interface is very friendly, use initialize Wizard mode, can be simple to use for beginners.

Multi Wii Copter (MWC)

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

Multi Wii Copter (MWC) flight control is a typical Arduino-derived product, is designed for development of rotor low-cost flight control, it had to retain the integrity Arduino IDE development and Arduino upgrade and the methods used. Due to the low cost, simple structure, more mature firmware, so the flight control has a lot of fans at home and abroad. In addition to supporting common other than four, six or eight rotors, the flight control is characterized by many strange aircraft types are supported, three rotors, such as avatar vehicles (BIcopter avatar style), Y4-rotor (as opposed for two axis), make the development of the flight control interest is strong, easy to gain your love.

KKMulti Copter

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

KK flight control is derived from Korea flew an open source project, was also the first widely accepted by rotary-wing flight control, early on in the open source development of the flight control, the flight control turned to the entire four-rotor is a shock.

The flight control only uses three low-cost single-axis gyro, combined with a simple four-channel radio control device, you can control the common three, four or six rotary-wing aircraft, and supporting "cross"-type, x-type, h type and opposed a variety of layouts. The flight control with three adjustable resistance adjusting sensitivity as a method of scheduling, retained the characteristics of early models of a gyroscope. As rotary-wing flight control starting an important witness, this "antique" classic flight control level, still has a lot of players.

Paparazzi(PPZ)

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

Paparazzi (PPZ) is a hardware and software open source project, which began in 2003, development objective is to create a flexible and powerful open source control project. PPZ feature is that the open source flight control solutions in addition to common flight control hardware and flight software and ground software, also contain station hardware, including modems, antennas and other equipment. Functionally speaking, PPZ has been close to a small unmanned aircraft system.

Another feature of this open source project is using Ubuntu operating system, it will be under ground station software, and development environment integrated with the system, officially called a Live CD. A CD jiafei control hardware to complete all the work from development to use.

PPZ the hardware version is by far the most popular Paparazzi (PPZ) Lisa/M v2.0. The hardware has a lot of extension interface, and use a separate IMU sensors that can be extended. It is also very popular in the early open source flight control practices, so you can DIY your desktop computer, the IMU escalating hardware with the sensor upgrade.

Autoquad flight control and ESC32 electronic speed control

Unmanned aerial vehicles how quickly becomes famous? Open source is behind

Autoquad flight control from Germany as an early open source flight control, Autoquad function is very powerful, but limited to the sensor, it is forced into a mass of MEMS sensors.

So-called analog sensors are sensors inside the chip does not have an integrated digital to analog converter (ADC) and the core operations, and micro-machined sensors directly changed by zooming in and hardware filtering in the form of voltage output, need to master AD single-chip data acquisition.

Because the sensor at different temperatures, the output value is affected, brought trouble to the calibration simulation of MEMS sensors. A lot of players when you use this control for the first time, have to use refrigerators to the sensor calibration, while some manufacturers in order to ensure the stability of bulk products, heating the circuit board only on the aircraft so that they maintain a constant temperature.

However, this calibration method for some hardcore brings extra fun, a lot of people happy. For most ordinary lovers, this is a problem in a lot of work. With the popularity of with factory-calibrated digital sensors, Autoquad, as the accumulation of history, has completed its mission.

However, another branch of the open source project ESC32 electronic speed control is gradual acceptance by the players. The ESC was the first electric with digital control interface, players can use serial ports, I2C interface and CAN interface to control the speed of the motor, this information faster than traditional PWM interface many times. Common PWM waveform update speed is 400 times per second, digital interface speed can reach millions of updates. Especially for multi-rotor aircraft dynamics are sensitive to changes in such communication is necessary. The ESC also supports speed closed loop, and detailed scheduling for the motor, which are traditional RC airplane electric adjustment can not be compared.

Of course, Autoquad is in progress, it released new flight control product Autoquad M4, the master microcontroller and sensor has been fully upgraded, using common STM32F4 and digital sensors. But the face of PIXHawk, APM has matured over the years advanced flight control products, has evolved from its predecessor become a rising star.

So, open source flight control to a large extent contributed to the four-rotor aircraft of such products into the homes of ordinary people, the development of drone technology, and can even help you to complete the dream of flying.

Real time voice translation New technology can turn speech into a 3D image

  Most of the time, had an impact on exchanges between the peoples of the world tend to be language problems. So, since the founding of new China, for the Chinese people to do it with the world in the true sense, the national policy has been promoting that learning a foreign language is one thing. From the earliest Russian to English, foreign language learning is also very important for many people. MIU MIU iPhone 5 Case

  With the development of science and technology, in order to make this barrier becomes smaller, other than learning a foreign language, many technology companies have begun developing a real-time translation tool. But most are conversions between text, such as Baidu and Google's translation system. In addition, some places have begun to voice translation system in real time, the difficulty relative to the text translation has improved a lot. MIU MIU iPhone 5 Case

Real-time voice translation? New technology can turn speech into a 3D image

  But now, a more advanced technology has been in development, this program was named the developer WordsEye, its capacity is: you can collect voice into text, and text content into a 3D image. It can understand your descriptive text, including the number, location, color, size, and status, and so on, you can tell it by voice, and let it show the image. Of course, the current database to understand the text, which is also very limited, and will be translated into some of the more common things.

  The project Chief Executive Gary Zamchick said: this program in addition to making sense of an art piece outside the show, it also has more uses, such as with VR equipment to use, develop more shocking and more realistic VR games or a few other things. At present, this program has an internal test, users can get access to the code for the experience.

Why 315 public WiFi security issues exposure worth your attention

"Lei feng's network as" the writer Liu Ming, millet MIUI Security Center Product Manager, Twitter: @ Liu Ming. This article has been obtained the authorization of the author and may not be reproduced without permission.

"Waiter, which is the WiFi in your House? A password? "

Now every time I go to a new restaurant, a bar, the first sentence is often not a la carte, but the waiter WiFi password.

The WiFi is really safe?

Do not know if you have this kind of experience, traveling to a city, connected to the hotel WiFi network on results found QQ stolen the next day.

Free WiFi is also mentioned in this year's 315 evening, the hosts through from the bait, the audience even offer free WiFi. After a while, all with what handsets system, self portrait photos, email accounts, passwords were stolen and projected on the big screen.

The curtain, the stage is followed by a "dark room", which are played by safety engineers "hackers", in analog to steal users ' private data.

The darkened room at the party, around us really exist? They are using WiFi, spying on us? It has free WiFi present said that in a previous incarnation.

Origin of the free WiFi 

Why 315 public WiFi security issues exposure worth your attention?

In July 2004, the United States Philadelphia first proposed the construction of wireless broadband networks based on WLAN standards, also called "wireless Philadelphia". Target is within the city limits and offers free outdoor WiFi Internet service. Wireless city construction began sweeping the globe, thousands of city under construction or planning wireless cities, to meet the needs of public access, public safety and public service.

Now, although it did not reach the level of Radio City, but free WiFi has become a standard of the restaurants, hotels, businesses to attract customers. As mobile Internet portal, is also the Internet service shall be competing for entrance.

Where there is interest, there's some scam, and the free WiFi hack get benefits in dispute.

Why insecurity of public WiFi?

315 party said, a half effort, hacker, hijack your phone information, exclude individual voyeuristic fetish, most of them are for profit. Hackers saw benefits of public WiFi?

1, steal account passwords

Fishing on the once connected WiFi, hackers can get all the account password for the application you are using, including micro-credit, QQ, Taobao, mailbox. Because a lot of people in different account password is the same as on the site, once a hacker intercepts that information, the login user can access all Web sites, including banking sites.

2, access to user privacy

Except for account passwords, use the data being uploaded will be intercepted, such as photographs, shopping information, chat, or even address book, liar according to them can pretend to be you, and then to lie to your friends and relatives, resulting in larger losses.

Free WiFi is how to be compromised by a hacker?

Now most of the WiFi fishing, are used in three ways:

(1) DNS hijacking

Why 315 public WiFi security issues exposure worth your attention?

 DNS (Domain Name System) is a distributed database to convert domain names to IP addresses.

 IP address is a string of meaningless numbers, is a protocol designed for computers connected. Domain name closer to natural language, is easy to remember and communicate for the communication between people. To establish a mapping between the domain name and IP address, DNS is.

Simply put, when you're in the browser's address bar enter www.Baidu.com and when the Enter key is pressed, DNS will automatically convert the www.Baidu.com access to IP addresses such as http://220.181.111.188/.

DNS hijacking is forced to modify the mapping relations, will visit the site to domain name's IP address to the hacker's own IP address and fake Web site you want to access. Users online, even if the domain name is correct, also open to hackers carefully forged fake website, and your account password, all were sent to cheat. In addition, hackers may also be by way of 302 redirect, to achieve the same results.

It's like, Beijing needs all of the Shun Feng express through SF distribution center in Beijing to transit, distribution center and a gang of robbers hijacked, forced conversion of all express shipping address to robbers. Then, all you express are owned by robbers shopping all over again.

(2) the ARP attacks

Why 315 public WiFi security issues exposure worth your attention?

Even if DNS has not been hijacked domain names successfully converted to an IP address (a series of virtual numbers) and then still need to be converted from an IP address on the server's MAC address (a real computer). This user message to be received and processed by the server.

ARP attack, was forced to modify LAN this mapping, all IP address corresponds to the MAC address, broadcast to hackers on the MAC address of your own computer, and fake Web sites to visit. Similarly, users go online, even if the domain name and the corresponding IP address is correct, because the last sent to the MAC address is wrong, only open the hackers carefully forged fake websites. OtterBox iPhone 4 Case

Also to express, for example, although there are no robbers hijacked SF distribution center, but the bad guys masquerading as a recipient of x, give customer service a call saying "I am x, mailing address changed! "。 So while also sent to SF distribution center, but on the way was converted into bad addresses, so express courier to the bad guys.

(3) false WiFi 

Why 315 public WiFi security issues exposure worth your attention?

Many people love to go to Starbucks to get wireless, sometimes it will find that there are two "Starbucks" WiFi, then be careful, most likely one of the hackers set up their own WiFi. When you connect to the WiFi, or normal Internet access, but all data will be a hacker's server to the Internet, hackers can easily view your account password.

How to prevent fishing WiFi1. Stop rubbing network behavior

Does not require authentication, no password is required for public WiFi risk coefficient is very high, may be behind the fishing traps. And now helps users get NET APP more aside moral questions aside, once users get application automatically connected WiFi fishing, resulting in property damage, it would lose.

2. use of data networks

Under absolutely safe and WiFi in uncertainty, when important operations such as online shopping, it is best to turn off WiFi, through data networks to ensure security. Operator's data package is already very cheap right now, if you all cannot be achieved with a data network, at least in important behaviors, such as online payment, financial management and mailbox operations such as switching to data networks.

3. alert name WiFi

Found more than one with the same name when WiFi, to be extra vigilant. Many hackers in the Starbucks, McDonald's, we love to get near the net, set up their own a WiFi with the same name, you may accidentally connect to WiFi on hacker hypothesis.

4. use professional software test network environment

Mobile phone security software. Network detection mobile security software on the market function, can effectively detect problems such as DNS hijacking and ARP attacks.

5. turn off automatic connection WiFi function

When a name like WiFi is found, many phones have automatic connection function, suggest that we turn this feature off so as not to be exploited by hackers, cell phones automatically connect to unsecured WiFi.

315 evening in a dark room, around us really exists. It's worth your attention.

Young mother taught us, don't talk to strangers. In the age of the mobile Internet, replaced this sentence "don't connect public free WiFi" also established.
