Cloud hosting and its application

Cloud hosting is used to save web information, run an application or email system management. With the current trend, a new cloud hosting regularly replaced old ones with advantages: stable, ready, flexible, cost,…

What is Cloud hosting?

In general, Cloud hosting places in a server to save, operate relating services and help them access from anywhere via the Internet.

Basically, Cloud hosting is made by Cloud server based on Cloud computing with many outstanding advantages. Therefore, Cloud hosting is usually used to:

Store and operate a website.

Operating the forum, personal blog.

Operate email system for small business.

Run software, tools.

Virtual environment to test, code.

Archive video, pictures.

Cloud acts based on Cloud Computing technology which used a server with the biggest boss in the world such as Cisc and saving system Cloud Storage with many principles. It uses Load Balancing technology among servers, providing faster access speeds than other types of Web Hosting, safe, security with Multi Downtime capability for Website.

Advantages of Cloud Hosting

Rapid Expansion: Cloud Hosting allows for more resources to be added quickly when needed and reduced when users do not need it. Users only pay for what they actually use, but always get the resources when there is a need.

Reliable: Cloud Hosting does not depend on any single hardware, so any faulty hardware will not affect the availability of cloud hosting, up to 99.99% uptime.

Full management: Cloud Hosting will include patches and operating system monitoring, as well as security firewalls, backup data from the high-tech cloud computing infrastructure.

Windows or Linux platform: Cloud Hosting supports both Windows or Linux operating system environments. So, users who develop on Microsoft SQL or MySQL, IIS or Apache, PHP or ASP.NET are all compatible.

Safety Data Backup: The storage system uses dual controller SAN and daily backup mechanism onsite and offsite at two points to ensure data is always available and continuously.

Flexibility: Cloud Server allows you to actively select the configuration and resources up or down according to actual demand. This is done quickly within minutes.

Features of Cloud Hosting

Optional Windows or Linux operating system

SLA server availability is guaranteed to be 99.99%

Narrow or narrow the resources when required

100 Mbps Internet connection

Services include firewall, monitoring, and patch operating system

Data is backup and restore server

24/7 technical support

In the recent year, there are many big websites in Viet Nam relating to Information Technology such as Tinh Te, VN – ZOOM, Sinh Vien IT, Nuke Viet, Chia Se Coupon, Ebooks VN, Thach Pham,… and social network such as Twitter, Facebook used Cloud hosting to save database and ensure system stability.

With high requirement nowadays, in the near future, Cloud hosting will become a new trend, new utilities for a new life.

Service virtualization

Service virtualization is one of the most significant invention in technology times, which is currently used in software engineering field. Along with the development of computing technology and network, virtualization is created and installed with an advance level. To find out the exact definition and and function of service virtualization, please read the article below.

What is service virtualization?

Service virtualization is an approach to emulate the behaviour of components such as API-driven applications, cloud-based applications and service-oriented architectures. This method is able to create virtual environment for software development and system testing.

Thanks to this type of virtualization, the software development and system testing can easily proceed. Unlike usual, the service virtualization allows the process to be lauched without accessing the live components. It is an advantage that most company leaders are interested in.

How service virtualization improves the modern technology

Service virtualization play an important role in a lot of aspects, which totally change how people work in computing system, engineer the software or even deal with the trouble happening. For example, with the virtual services, participants can easily connect with each other, share information, resources, transfer the data or finish daily tasks directly on the virtualization system. This will be much more time-saving and convenient than the traditional one.

Moreover, in case there are any problems occur, it can be solved in such a short time. The service virtualization allow users to discover the problem to fix it, and protect the data from being get loss at the same time. Therefore, a lot of company tend to create service virtualization to enhance the working efficiency and minimize the risk during administrating the whole complicated system.

This type of virtualization is recognized by vendors, industy analysts, industry publications. They tend to focus on the benefits and advantages of it.

The application of service virtualization

Service virtualization includes creating and deploying a virtual asset which stands in for a dependent component with appropriate performance. It will participate directly in the process of application testing progress.

Service virtualiztion is commonly applied in website service. This involves listening for an XML message over http, jms, mq and so on.

Thanks to the benefits of service virtualization, people currently manage the computing network and software engineering in more efficient way. Many companies have used this virtual network to encourage better result in administration, business and so on. It is supposed that this type of virtualization is a key of success in software and computing technology, so each system should be installed with service virtualization.

Cyber Security Threats to Businesses

For a business, it is quite critical mitigating the cyber security threats that may affect organisation’s goodwill or businesses financially. An enterprise and its top management should be well aware of taking necessary actions.

Misuse of Company Assets:

It is very common that employees maliciously misuse the company assets, which remains an on-going threat to the organisation. Such misuses occur during the normal course of duties being performed by the employees, which is difficult to prevent. Monetary personal gains inspire guilty employees performing such acts irrespective of any cadre i.e. from top executives to the lowest level. Another high risk pertains to theft of the physical devices, which may store, or process or transfer business information. Such devices may include laptops, smartphones, pen drives, etc. stolen from office premises, personal vehicles or employee residences, mostly owing to employee’s carelessness.

In order to mitigate such risks, the organisation should regularly arrange back-ups for their data and should encrypt all the mobile devices. Employee awareness programs should be conducted. IT policies should be formed to discourage employee perpetrating from such acts and monitoring should be strengthened to timely identify such insider employees.

At PSI, we use various techniques in-line with ISO 27001 standards, like disaster recovery plan that has extensive details covering the security aspects not limited to only data and application back-ups, laptop encryption using bit locker, etc.

Infringements at Point-of-Sale (PoS) Terminals:

Due to infringements at point-of-sale systems or smart cash registers, large volumes of thefts pertaining to payment card information have been reported. These kinds of attacks pose threats for MSME businesses like grocery stores, restaurants, etc. These attacks involve compromising the PoS device, installation of malware on PoS node for collecting the magnetic strip information, retrieving the stolen data for using it for the financial gain.

Mitigating this attack can be performed by avoiding the use of remote access products and services like PCAnywhere, Microsoft RDP, etc. used to manage PoS nodes. Using anti-virus products for effective identification of popular keystroke logging tools, like Perfect Key-logger, etc. The operator employees of PoS should not be allowed to access the internet for other activities like e-mail access from these PoS terminals. Finally, the operating systems of the PoS terminal should be hardened.

At PSI, we do not allow remote access to the network without a virtual private network. All the systems are protected by corporate licensed antivirus software whose virus definitions are updated regularly, with close monitoring of all the user system on the regular basis.

Denial of Service (DoS) Attacks:

This attack shuts down all customer interacting websites. In such an attack, the internet protocol is exploited to reject other users from the genuine access to the information or systems. The individual or some group of individuals introduces these attacks.

Such attacks are done for various malicious reasons, like rescind the ability of the device to function by deleting or changing configuration information or power interruptions, etc. To vitiate the ability of the device to function, like opening many simultaneous connections to the single device, etc. To engulf the bandwidth capacity of the network device. The attack can be in the form of Distributed Denial of Services (DDoS), where a blend of DoS attacks are performed in concert from various hosts to punish the target host from further serving its function. Normally, these attacks include SMURF attack, SYN Flood Attack, Ping of Death, Teardrop Attack, etc.

In order to mitigate such attacks, network design should be such that it provides high availability and redundancy, the network should be protected by the firewall, network devices, and hosts should be hardened and several layers of security should be applied to the data and the network.

PSI uses Dell Soni firewall to protect its network and devices. The network is designed with state of art, ultra-modern robust devices that minimize the risk of DoS.

Web Application Attacks:

This is the most common type of data breach, in which weakness of the web application is abused. The unfixed application vulnerabilities provide the way to the attacker for taking control of the machine’s and have access to the system resources. System resources are not limited to intellectual properties, personally identifiable information of the organization, but also may have unencrypted and unguarded financial information like credit card, banking details, etc. These attacks typically include SQL injections, Zero-day Vulnerability, URL Interpretation, Cross-Site Scripting (XSS), Buffer Overflow, etc.

The paramount protection for these attacks is to have the secured applications developed, keeping up-to-date patches, having secured application configuration over the applications and hosted servers.

The developers at PSI use industry best practices while designing and coding the applications for its customers. The quality analysts pre-checks all such attacks on the applications to avoid any sort of security related bug leakages.

Why C is so popular and still the best programming language?

Computer programming has changed a lot since the 1960’s but one language has managed to stay the same through thick and thin C. When C compilers had gotten into the hands of the common man, things really exploded. At a glance, there have nothing special about C compared to Ruby or Python, but C is way more powerful than anything.

There are many programming languages, today, that allow developers to be more productive than with C for different kinds of projects. There are higher level languages that provide much larger built-in libraries that simplify working with JSON, XML, UI, web pages, client requests, database connections, media manipulation, and so on. But despite that, there are plenty of reasons to believe that C programming will remain active for a long time. Here are some reasons that C is unbeatable.

1. Portability and Efficiency - C is almost a portable assembly language. Before C, programmers had to rely on Assembly. Assembly is no doubt a great language, but there was one drawback - it was based on system instructions differing between CPUs. When C came along, it break all the barrier. It is as close to the machine as possible while it is almost universally available for existing processor architectures. There is at least one C compiler for almost every existent architecture.

2. C has no pre-defined style - Despite its reputation of chat-channel flame wars, the fact that C has no style guide can actually be quite good. In a sense, C teaches us to accept the fact that not the only one coding in the world. Macro naming, function naming, and data structure naming all depends on your preference of style.

3. Deterministic Usage of Resources - Arbitrary memory address access and pointer arithmetic is an important feature that makes C a perfect fit for system programming. At the hardware/software boundary, computer systems and microcontrollers map their peripherals and I/O pins into memory addresses. System applications must read and write to those custom memory locations to communicate with the world. So C’s ability to manipulate arbitrary memory addresses is imperative for system programming.

Another common language feature that system programming cannot rely on is garbage collection, or even just dynamic allocation for some embedded systems. Embedded applications are very limited in time and memory resources. They are often used for real-time systems, where a non-deterministic call to the garbage collector cannot be afforded. And if dynamic allocation cannot be used because of the lack of memory, it is very important to have other mechanisms of memory management, like placing data in custom addresses, as C pointers allow.

4. C is small and simple - C has a very small runtime. And the memory footprint for its code is smaller than for most other languages. Since C is fully based on variables, macros, functions, and structures, there isn't all that much to it. Due to this, C has been embedded on almost any modern microprocessor, from fridges to alarm clocks. It lacks the expressivity of sophisticated OOP or functional languages, but its simplicity means it can be picked up quickly.

5. Reasons to Learn C - C is not a hard language to learn, so all the benefits from learning it will come quite cheap. Since almost all programming languages nowadays are themselves implemented in C, knowing C basically gives you a free ticket to knowing all programming languages. It's true to say that C is very different from C++ and Objective-C, but from a learning standpoint they all aren't that far apart. Of course, C is a procedural language, which means classes and objects are non-existent compared to languages like Python, but Python’s class model itself is written in C. This means that understanding C may not teach you object-oriented programming, but it will teach you how it was conceived, designed, and implemented.

6. Many Interesting Projects to Power the World - C is the best programming language today is still the fact that it simply powers everything. From your phone to your Wifi, no other language provides the level of hardware interaction with the practicality. Many of the C projects that exist today were started decades ago.

The UNIX operating system's development started in 1969, and its code was rewritten in C in 1972. The C language was actually created to move the UNIX kernel code from assembly to a higher level language, which would do the same tasks with fewer lines of code.

Oracle database development started in 1977, and its code was rewritten from assembly to C in 1983. It became one of the most popular databases in the world.

In 1985 Windows 1.0 was released. Its kernel is mostly written in C, with some parts in assembly. Linux kernel development started in 1991, and it is also written in C. The next year, it was released under the GNU license and was used as part of the GNU Operating System. The GNU operating system itself was started using C and Lisp programming languages, so many of its components are written in C.

But C programming isn't limited to projects that started decades ago, when there weren't as many programming languages as today. Many C projects are still started today.

smartphone affects memory, ability to handle

A recent study indicates that our obsession with smart phones can cause decreased brain power.

According Iflscience, the younger generation of today are often accused of being tended to depend on smartphones more and more . A recent study showed that smartphones can even reduce the power of our intellect.

This study has been published online in the Journal of the Association of Consumer Research. Accordingly, the scientists found that smartphone reduce cognitive abilities of users. Because all information is available when they need it. They decided to test the hypothesis that “brain drain” and realize that if the smartphone in the neighborhood. It will do “limited cognitive capacity of us and leave fewer resources for other tasks”.

The brain has a limited attention capacity-the cognitive resources “limit”-controls of attention and other cognitive processes. When the phone is in the near side, the brain uses this resource section to try to reduce our attention to your phone. And reduce the resources to perform the tasks, that is, the performance of these tasks is affected.

The researchers discovered that when to your Smartphone is in sight, the object of research is reduced ability to perform simple tasks and remember. This remains true even when the phone is placed in the bag or the next.

To perform this study, they conducted the experiment 520 University students about their knowledge and memory. When there is a telephone on the side. The participants have answered the test questions in mathematics, memory and reasoning. While their phones are to randomly on the desk, trouser pocket, handbag or in the next room.

The results showed that those who hold the phone on their desk have scored score less than 10% in the test of concentration and memory. They also respond more slowly in the test speed. In fact, even when their phone is turned off or in “do not disturb”. They reach points lower than those who have put the phone in the next room.

This means smart phones reduce the ability to memorize and handled by humans. Not surprisingly, when scientists discovered that people who depend on the phone often negatively affected the memory when the device is placed beside them. The researchers say that is not the intelligence of those who were distracted because the test to check the messages on smarpthone that their minds are focused on trying to not think about their phone.

Cloud Bigtable

Indexed is showed for a single value of each row, known as the row key. Cloud Bigtable is a concept about storing a large of individual keys data with low abeyance. This method support ideal data for MapReduce operations, which require low latency.

Cloud Bigtable works with multiple clients containing a supported development to Apache HBase 1.x Java library. By integrating with Apache ecosystem, it makes use of open – source Big Data software.

Cloud Bigtable advantages

Incredible storage: Cloud Bigtable storage ability can reach terabytes even petabytes of data which used in hundred of machines in your cluster.

Simple management: By updating and restarting regularly, this application automatically maintains high data durability. No need about managing masters, clusters anymore, the only one that you should care is designing your table schemas, other works, Cloud Bigtable will do.

When Google added other services such as Youtube, Google Docs, etc., there is unsuitable if we keep a block-based data management system. To solve this problem, basing on GFS platform, Google added Bigtable as a data management technology, which the same meaning with a database.

Everything was managed under the table with a million webpage which needs to save. This table includes keyword, a language in column and URL in the row. Web content will be saved in the corresponding boxes with information about the time of recording – the timestamp.

Basically, the way that Bigtable store data is quite similar with GFS:

Reading data is a priority.

Changing is made in the supplement form, which attaches with a version, not directly changes old data, even data for Google Docs services is managed in this format.

However, this table management format is quite innovative that help overcomes the previous difficulties by Google expanding the number of services that rely on GFS.

Some services that we use today such as: mail, video, calendar,… updated newer and more accurately.

=> What is Cloud Bigtable good for?

Cloud Bigtable is the meaningful application which requires high throughput and scalability for non-structured value/ key data. Cloud Bigtable is good for:

Marketing data: relating to purchasing histories and customer preferences.

Financial data: using in transaction histories, currency exchange rate, and stock price.

Internet of things data: usage reports from home appliances and energy meters.

Time series data: using in CPU and memory storage over time for multiple servers.

=> Cloud Bigtable storage model

It stores data is composed of rows and columns, each row will describe a single entity and each column is individual values of each row. With different timestamps, each row or column intersection can include multiple cells.

A few things to notice in this illustration:

The table includes one column family, the follows family. This family includes a hundred column qualifiers.

Column qualifiers have the responsibility as data. Taking advantage from the smallness of Cloud Bigtable tables, column qualifiers can be added on the fly.

Free hosting – You know what?

Currently, there are many web hosting providers with different hosting services. When you first visit the home page of the provider, you must be very confused because you do not know what storage service to choose for your website.

What is Hosting?

Hosting is a type of hosting on the Internet that allows the visitor to store all Web sites, information, documents and images of the Website onto an Internet server. Hosting is also the place where all transactions, exchange of information between the Website with Internet users and the support of Internet software operate.

Parameters of Hosting

Hosting capacity: is the amount of space you are allowed to store your data on the server’s hard drive. If you compare the hire of a similar web hosting to an office or a workplace, then the capacity of Web Hosting can be imagined to be the entire office space you hire.

Bandwidth hosting: is the amount of data exchanged between the website and the website user. For example: If you upload to your website a file size of 1MB and have 100 customers download the file back then you spent a total of 101MB bandwidth.

You can imagine bandwidth as the size and width of the car. The greater the bandwidth, the greater the number of visitors at the same time, so choose a broadband provider.

FTP stands for File Transfer Protocol – a file transfer protocol on the Internet. When the server supports FTP, you can use the FTP client software to connect to the server and upload the data files as well as update your website easily.

Hosting Controller or Cpanel: The web hosting software comes with hosting support for clients to actively manage and configure the hosting package. Sacomtec is using the latest HC7C software from Hosting Controller to help customers manage their hosting packages efficiently and effectively. fast.

The requirements and features needed of Hosting

First of all, speed. Servers running Web services must have a configuration that is large enough to ensure smooth handling for large numbers of visitors. Must have high-speed connection to ensure no data congestion.

– Servers must be maintained, updated and maintained by the system administrator regularly to avoid technical and security risks.

– Hosting must be large enough to store all information, data, images …

– There must be enough bandwidth to serve the exchange activities of the Website

– Must support FTP server access to update information.

– Support for programming languages ​​as well as databases for executing software on the Internet or writing tools available for website transactions such as sending mail, uploading through the Web, managing products, news …

– Full support for E-mail services such as POP3 E-mail, E-mail Forwarding, DNS ..

– Has a Web Hosting management interface to easily manage website, FTP accounts, Email ..

– Do not insert the banner ads of the provider.

Hosting service is a service of renting space on server, usually this server requires very high configuration, strict compliance with power supply, temperature, humidity, … during operation. Enterprises have to spend quite large expenses to invest in servers, technology equipment, IT staff, … so often will choose hosting services to save costs.

Email Hosting Service

Email hosting is a special email service other than free email services, email support or other free webmail. Businesses often run their own email archiving services, or email hosting by their own domain name, to increase the credibility and authenticity of the messages they send. Email hosting allows you to customize the configuration and large number of accounts. What is Email Hosting? Email hosting is a dedicated email service that is built on dedicated server clusters for extremely high availability and stability. Outgoing IP’s are always allowed from other EMAIL servers, so incoming and outgoing emails are always forwarded. => Advantages of Email Hosting Service: – Outgoing large: Unlimited (with the condition that Email is legal) – Large Email Capacity: Unlimited (Depends on Service Packages) – Email sent out to the inbox of other email servers like Google, Yahoo, Webmail .. – Server supports SPF / DKIM records, anti-virus and spam support. – Unlimited bandwidth usage All of the features mentioned above, if you use Email with hosting, free is not possible. Comparison between Email Hosting Service and other Email services Email hosting included: This service is used by many companies thanks to the registration for hosting companies will be accompanied by Email. However, due to sharing with many customers (Share hosting), this service has disadvantages such as: – The number of emails sent in 1 day is limited from 500-1000 Email – Small Email Capacity: Depends on the size of the hosting package. – Email can be in Spam and blocked by other servers because the IP of the server is listed in the Spam list. – Sending and receiving emails may be interrupted due to server overload or downtime, maintenance, and maintenance. – Abuse Bandwidth usage of hosting. Email Hosting Service: This is a dedicated e-mail service built on dedicated server clusters for high stability and availability. The outgoing IP of the service is always allowed from other Email servers so incoming and outgoing emails are always forwarded. This service has many advantages: – Sending out big: 7200 emails / day – Large Email Capacity: 2GB – Email is sent out to the inbox of other email servers such as Google, Yahoo, Webmail, … – Server supports SPF / DKIM records, antivirus and spam support. – Unlimited Bandwidth usage. The above features if using Email with hosting, free is not possible. Email Hosting Service is an e-mail service dedicated to agencies, organizations, enterprises, schools, research institutes or customers who wish to use email with their own domain name and have built a secure server system. The ability to send and receive large Email with features fast, effective, stable, high security. This is an email service provided on a dedicated server system with high security features. Unlike Free Email or Email hosting services, emails sent from the Email Hosting system are always rated with high reliability, so emails are always sent to Inbox.

Security in cloud computing

Today, security in cloud computing is not strange term for us, especially computer technology develops day by day. We need to understand clearly that if you want to save your important documents in computer.

The concept ?

Cloud computing is computing clay model that use technologies and be developed base on the internet.

Security in cloud computing is that use resources of cloud computing to set up protecting activities. Although stabilization of  security in cloud computing is controversy thing, it is still used popular in the world.

Ability of security in cloud computing.

In cloud computing, data is shared with single computer without focusing where is the data warehouse.

In reality, the cloud computing server have pause times. If user choose concrete cloud service provide, user will be limited authority that makes the risks about security in cloud computing.

Cloud computing do not allow user control directly saving  data infrastructure. Therefor, freedom of security in cloud computing is so small.

Problems of security in cloud computing.

The interior threats

The exterior threats

The losing data

The interrupted service

The multitasking problems

The losing management

Advantage of security in cloud computing

Investing fees is small

Processing speed is quick without base on service and local place.

Easy to extend and upgrade.

Obstacle

Information and data of user are not guaranteed about privacy.

The cloud computing centers might have some trouble that make cloud service be paused suddenly.

Ability to lose data.

If cloud computing is attacked, all of data will be stole.

Cloud dataflow

Cloud dataflow

Cloud dataflow is a common term used in Google Cloud platform. According to the most exact definition, it is a reliable execution for large-scale data progressing. In computing system, computer technicians and software developers usually possess and manage a large quantity of information. This increases the likelihood of data leak and loss. However, these problems will no longer threat the information management if cloud dataflow is applied in system.

What is cloud dataflow?

There are various definition of cloud dataflow. However, the most specific and accurate one is that cloud dataflow is the unified programming model and a managed service. It is in charge of developing and executing a wide and complicated data processing

Thanks to Cloud dataflow, users easily manage the resource and optimize the performance

The feature of cloud dataflow?

Resource management

In common, users manage the information and put them in a logical system by hand. This approach can cause a leaking potential and waste much time. However, cloud dataflow is able to execute automatically the required processing resources

On demand

All resources are provided by dataflow to meet users’ requirement. People are likely to apply and use these available resources instead of buying reserved compute instances. Therefore, the time spending on preparing or seeking for resources will be minimized considerably

Intelligent work scheduling

Cloud dataflow provides such an intelligent work scheduling which automates and optimizes every part of the required work. Each task will be arranged automatically and logically, then put into the exact working schedule

A logical schedule can rebalance the lagging or unstable work. Therefore, the capability of disorder tasks and work system will no longer happen.

Auto scaling

Cloud Dataflow has function in scaling the available resources to balance each categories. This feature will bring a better overall result. The auto scaling function also keeps the price and performance in a moderate level

Unified programming model

Cloud dataflow creates and supports a programming model with specific operations, powerful data windowing, great accuracy. This professional model increases the steady system and constant control

Open source

Cloud dataflow is an open and free information source. Hence, users can easily get access to the available resources and apply them for programming model

The open source also allows users to give an alternative pipeline infrastructure. That is the reason why the information management model become more flexible

Integrated

Cloud dataflow can be integrate with cloud storage, cloud pub, cloud bigtable, bigQuery to improve the working result. In different location or computer system, you are able to interact with other sources and contact partners. This function allows to broaden the working space globally.

To sum up, Cloud dataflow has brought a big change to computing technology as well as human life. To take use of dataflow ultimately, it is recommended to combine and integrate with other source of Google Cloud platform such as cloud storage, Cloud pub, cloud datastore, cloud big table, bigquery and so on

Your devices could soon be powered by ocean waves

A sustainable future powered by the sea could soon be a reality.

Researchers at the Okinawa Institute of Science and Technology in Japan have been generating electricity through currents, using special underwater turbines. On Sept. 20, they announced that their project—dubbed Sea Horse—was a success and ready for commercial application.

The implications are “huge,” according to lead researcher professor Tsumoru Shintake. “Using just 1% of the seashore of mainland Japan can [generate] about 10 gigawatts [of energy], which is equivalent to 10 nuclear power plants,” he said in a press release for the Okinawa Institute, which is a graduate school on Okinawa, an island in the East China Sea.

Plus, wave energy has the added benefits of being cheap and clean.

Since 2013, the researchers have been strategically placing specially-designed turbines along the shoreline to convert the kinetic energy of the north-flowing Kuroshio current off the Japanese coast into usable electricity.

The turbines are inspired by the ocean; their flexible blades bend like dolphin fins and turn at a speed that ensures creatures can escape if caught in their clutches.

The turbines’ support structure is modeled on the flexibility of flowers. Built to withstand extreme weather and move with the relentless waves, rather than stand rigidly against them, the turbines bend like the stem of a flower bends back with the wind, Shintake says. They are anchored to the sea floor with mooring cables.

For ideal wave conditions, the turbines are planted among coral reefs and by tetrapods, which are pyramid-shaped cement structures built along coasts to break waves and prevent coastal erosion. The axis is attached to a generator, which converts wave energy into usable electricity that is then delivered by cables to land. A ceramic mechanical seal protects electrical components inside the turbine from saltwater and corrosion for up to 10 years.

Shintake says that the turbines, which he calls “intelligent tetrapods,” not only constantly generate renewable energy but also help to protect the coast from erosion. “I’m imagining the planet in 200 years,” he said. “I hope these [turbines] will be working hard quietly, and nicely, on each beach on which they have been installed.”

Google Pixel Buds—wireless headphones that help you do more

What if your headphones could do more than let you listen to your favorite music? What if they could help you get things done without having to look at your phone? What if they could help you answer (almost!) any question just by asking, or even help you understand someone speaking a different language?

We wanted to make a more helpful pair of headphones, so today, we’re introducing Google Pixel Buds. These wireless headphones not only sound great, they are seamless to use and charge, offer help from the Google Assistant, and have a few extra smarts so you can get the answers you need while keeping your eyes up.

=> Fit them, charge them, pair them—made simple

From getting the right fit, to keeping them charged, Pixel Buds are really simple to use. They’ve got a unique fabric loop, making them comfortable, secure, and quick to adjust without having to swap out pieces. We put all the audio controls into a touchpad on the right earbud, so there aren’t any buttons hanging on the cord. Just swipe forward or backward to control volume and tap to play or pause your music. Charging and storing them is easy—they nestle right into a pocket-sized charging case that gives you up to 24 hours of listening time*. And pairing them is a cinch. Just open the charging case near your Pixel or Android phone running Android 7.0 Nougat or higher with the Assistant, and your phone will automatically detect them and ask you if you want to connect.

=> Get help from the Google Assistant with just a touch

Pixel Buds bring Google smarts right to your ears, with answers and intel that would make James Bond jealous. Touch and hold the right earbud to ask your Assistant to play music, make a phone call, or get directions, all without pulling out your phone. If you have an upcoming meeting or you’re waiting on a text from a friend, the Assistant can alert you to a calendar event or incoming message, and even read it to you if you can’t look at your phone at that moment.

=> Be multilingual with Google Translate and Pixel

Pixel Buds can even translate between languages in real time using Google Translate on Pixel. It’s like you’ve got your own personal translator with you everywhere you go. Say you’re in Little Italy, and you want to order your pasta like a pro. All you have to do is hold down on the right earbud and say, “Help me speak Italian.” As you talk, your Pixel phone’s speaker will play the translation in Italian out loud. When the waiter responds in Italian, you’ll hear the translation through your Pixel Buds. If you’re more of a sushi or French food fan, no need to worry—it works in 40 languages.

Pixel Buds come in three colors—Just Black, Clearly White and Kinda Blue—to match your Pixel 2. They’ll be available in November for $159 in the U.S. and are available to pre-order today. They’re also coming to Canada, U.K., Germany, Australia and Singapore in November.**

With Pixel Buds, we’re excited to put all the power of the Google Assistant into a pair of headphones you can take with you everywhere, so you can easily control your tunes, get walking directions to the nearest coffee spot or have a conversation with someone from another country without ever pulling out your phone.

Server hosting

In the past, it was not easy for human to create and manage hundreds of computers in the same system. However, these problems have been solved thanks to the existence of server hosting.

What is server hosting?

Server hosting is online storage and sharing service which allows connected computers and devices to exchange and process the information. It is also regarded as hosting space which equipped Internet service such as world wide web (www), FPT, Mail,… The website and data will be stored in this space.

For example, when you want to share documents to other members, you have to upload it onto the infracstructure that they are able to get access to. Therefore, in different location, the legal accessors can download, upload and tackle with shared documents.

The type of server hosting?

There are 4 main types of server hosting which are shared hosting, collocated hosting, dedicated server and virtual private server. Each hosting has its own function which can be applied in different system for different purpose.

=> Shared hosting

Shared hosting is known as the server hosting which allow users to share the data in the same infrastruction. All computers and devices are capable of getting access to, exchanging, transforming and tackling the information, documents, images and so on.

=> Collocated hosting

Collocated hosting is quite different with shared hosting. This type of server hosting provides space for hosting to rent. Depending on the demand on datastore, users will rent a space which is capable of store and keep the uploaded data.

=> Dedicated server

Dedicated server runs individually in the system, which is independent of any other computers or devices. Because of private operation, this type of server hosting is not likely to be impacted by the other parts of the system. This allows the server hosting to accelerate the working speed considerably.

=> Virtual Private Server

Virtual Private Server is quite commonly used in modern computing system. This server hosting creates virtual computing environment in which participated computers and devices process in the same infrastucture. All the process will be managed and administrated efficiently. Moreover, in case the problems occur, computer technicians can easily figure out and fix them.

=> Why the server hosting should be chosen?

The server hosting is highly recommended by a lot of users because of its advantage. A professional, stable and secure server hosting is supposed to support the administration in the system and reduce the cost.

Moreover, the cost for purchasing and install each server hosting is not too expensive. It is worth investing in the computing system of every company, especially the global one.

It is crucial that every company should install their own server hosting. This enhances the ability of exchanging information and tackling with the problem occuring in the process. In technology times, it is no doubt that owning such an advance and qualified server hosting will encourage the owner to achieve better result.
