Solar Shirt to Charge your Cell Phone & Tablets

Solar Shirt
A city-based scientist has come up with a concept of a " solar summer shirt" which will come with with inbuilt solar cells and fans to keep the wearer cool during hot days.


"We are trying to develop technology to fix small solar cells either into the fibre of a shirt or in its pocket," said Santipada GonChaudhury, a specialist in photovoltaic system engineering and design.

GonChoudhury says the shirt could produce around 400 watts of energy with the help of solar cells whose size will vary from 2.5 inches to 3 inches.

He said the shirt would store enough power to charge cellphones, tablets or other digital devices.

Explaining the concept, the scientist said the shirt will have two layers, one of which will have two to four small "fans" which will work on solar energy. The size of these miniature fans will be smaller than those found inside a computer.

"Suppose a person is 5.5 feet tall. Then the amount of sun rays that fall on every square feet of his body is sufficient to create 400 watts of energy by using solar cells - enough to charge mobiles, tablets, ipods etc," GonChoudhury told PTI.

The Ashden award winner, who teaches at the Bengal Engineering and Science University, has submitted the research proposal to the Science and Technology Department of the central government.

VPS Hosting Tips & Tricks

A VPS, or Virtualized Private Server, can be a great choice for businesses who have outgrown the constraints of a shared hosting plan but don’t need the resources of a dedicated server. By offering companies a full-fledged server, businesses can stop worrying about sharing the allocation of RAM, hard disk space, and bandwidth with others. And since it’s a Virtualized Private Server, they can do so without having to fork out the expenditure to buy all the necessary hardware.

The first thing you need to consider when looking into a VPS hosting plan is your needs. What level of support will you require? Mentioned below are the three types of service offered.
Managed VPS Hosting Plans

With fully managed VPS hosting services, the owners of the servers are responsible for administering your server. That means that if you choose to install Linux, they will be responsible for setting it up. If you choose to install Windows, then they will be responsible for installing Windows. As well, if you decide that you want to make changes to the way that your web-server operates, or add additional software/applications, then they will take care of that for you. This is a great solution for people who know what they need to do but either do not have the technical ability to do it or do not have the budget to hire an expert. Because you are going through the host provider themselves, they have systems in place to monitor your server and make sure that performance is optimal. If something does happen, then they are able to get on it straight away to fix the issue. The cost of managed VPS hosting is higher than other plans, but keep in mind that you are hiring 24 hour technical support to continuously monitor your server. In short, managed VPS hosting offers a worry free, support heavy service.


Unmanaged VPS Hosting Plans

Unmanaged VPS plans offer an even higher level of flexibility for businesses. In an unmanaged plan, the client is hiring the services of the virtual server alone. Unlike a managed package, they receive no further technical support from the hosting company other than the regular maintenance of the entire VPS system. Whereas with a managed plan, the client would say what operating system they would like to install and the hosting company does it, with an unmanaged plan they must install it themselves. This is a money saving option for someone who either has the technical expertise themselves or the resources to hire a server administrator. Because you are only paying for the VPS service and not the technical support that comes with it, the price of an unmanaged VPS package is considerably lower than that of a managed one.

Semi-Managed VPS Hosting Plan

 A semi-managed package is the blend between that of a fully autonomous VPS system, and a fully administered one. With this package, you can choose what features are necessary to be managed and which can be handled on your own. Generally this sort of package is good for those who want to make sure their basic needs are covered (OS, Network, etc...) but feel comfortable installing and maintaining their own custom software.
VPS Hosting

Here is a quick rundown of what each package offers:

    Managed

The provider takes care of all network, software, and hardware issues, including custom software.

    Unmanaged

Provider handles network and hardware support. However the user is responsible for all software installation and performance issues.

    Semi-Managed

The provider takes care of all network software and hardware issues, but not custom software.


 What VPS Option is Best for You?

  • Know what you need before you go looking for it: Before signing a contract with any VPS hosting provider, figure out what your requirements are. How much bandwidth do you expect to use? What is your estimated traffic growth? How much RAM and what CPU do you need to be able to run your business?                                                                                                                                             
  • More RAM is always better: When looking at different packages, look for those that have high amounts of RAM available. This is where most servers fail. By assuring that you have enough RAM, you will assure that your site will not be going down.
     
  •  Research all the other technical details: Many companies will show off an area that they are especially proud of, but try to obscure the fact that they are lacking in another. Make a list of what is crucial for a server to run and make sure you find out all the details for each one.
     
  •  Research what larger companies are using: Do a Google search for what companies are available and who uses them. Many host providers list their largest clients on the front-page of their website. You can rest fairly assured that if a million dollar company feels good enough about this provider, then they are probably worth their cost.

Shared Hosting Tips

Shared Hosting
 In hosting conferences and forums this is a question we’ve heard all too often. But despite all the dire predictions in the past decade, shared hosting is still alive and flourishing.

Every web host on earth has a shared hosting plan, and all website owners start hosting with a shared space. It is a market that just cannot be ignored, and is still the most competitive market.

What does it take to succeed in this market? There are companies which keep growing year after year, and there are companies which stop growing after they get about 10 servers. Here is a quick overview on what the winners do right, and thus ensure their brand keeps attracting new customers.

Ensure fair share to everyone
One of the major disadvantages touted against shared hosting is the poor performance and poor reputation through abusive neighbors. To be known as a reliable shared host, you should be able to quarantine abusive neighbors and negate any threat to security/reputation.

Resources that are misused the most are I/O, Memory, CPU, Disk space and Bandwidth; in that order. There are several resource moderation products now available which can do this for you in your servers. Choose one that closely integrates with the control panels you have, and establish an upgrade path to VPS for customers who constantly exceeds the limits. Examples of resource moderation products are CloudLinux, BetterLinux, 1H, etc.

Malware traffic from your network can be controlled by deploying hardware or software filters on FTP, HTTP and SMTP traffic. Examples for software filters are CXS, Linux Malware Detect, Atomic Secured Linux, etc. Examples of hardware filters are Cisco Anti-X devices, Fortinet Fortigate series, Barracuda Web & Email firewalls, etc. Additionally, make sure that your Acceptable Usafe Policy is enabled with zero tolerance for accounts spreading malware as you can cite them when taking action against defaulting accounts.

Lend a prompt hand of assistance
Legends are made at the time of distress. How you assist your client when he is in need will make or break your brand. Building a support system which has the following qualities will build your brand.
• Easily accessible over phone/chat/email
• Knowledgeable and confident
• Friendly and empathetic
• Available 24/7

Support is the single most time consuming element in running a shared hosting business, and finding the right crew for this job is one of the most important decisions you would make. You can either have a crew of in-house support staff, outsource the whole process, or run a combination of in-house and outsourced techs.

Watch your farm like a hawk
Establish an effective monitoring system. If there is trouble, you should be the first one to know. You should keep checks on your IP space reputation, network health, hardware health, and the health of services being delivered.

Additionally, your monitoring solution should be able to give you a trend graph on how the different farm metrics are performing. This should in turn help you plan on how to grow your farm. Open source software include Nagios/Zabbix for alerting and Munin/Cacti for trend display. Commercial solutions include Monitis, iHwak, Datadog, etc.

Insure against single point failure
Achieve redundancy on as many farm components as you can. If you are in a decent data center, you would already have network and power redundancy. Aim for achieving redundancy in individual server components like PSU, hard disk, network card etc. Enable health checks on your hardware devices, so that you will be immediately alerted when the performance starts to degrade. Eg: SNMP has capability monitor hardware parameters.

If your budget allows it, get a cloud solution. In any cloud solution implementation, the standard design recommends multiple redundancy points.

Be prepared for the worst
Disasters happen. It happens at the most unexpected time, and despite all precautions. Web hosting owners understand such is the way of life. But a “legendary” web host will be able to bounce back from a crushing blow within a matter of hours.

Your customer’s data is your strategic asset. Store it in an offsite backup, and check its consistency periodically. Establish contingency reaction procedures, like how to contact customers, who to do what, etc, and TEST them periodically. Keep a fail-over mirror for your company website so that your customers can reach you at any time.

This process is your life line. You wont need it every day, but when you need it, there is nothing else to replace it.

Empower your clients
Establish a rich self-help portal. Customers would ideally like to use a system where everything is intuitive and self-explanatory. Establishing a self-help portal which tells him or enables him to easily manage his account will help you save precious support time, as well as increase customer satisfaction rate. Eg: “Support knowledgebase”, “Server status monitor”, “Billing management”, “Domain management”.

Advertise a unique capability
Define your Unique Selling Proposition and target market. Cheap hosting is no longer a crowd puller. The market is so big that website owners look for specialists in what they want. You will need to establish a unique identity in the market of shared hosting. What do YOU offer that your competitors does not?

A few examples are: “SMB optimized hosting”, “Wordpress hosting”, “Bullet proof secure hosting”, “Anti-DDOS hosting”.

Once you have identified your strength, define a profile of your ideal client. List down all his possible requirements, and work towards being the best in providing solutions to those requirements.

Enforce the rule of the land!
Define the Acceptable Usage Policy for your hosting based on market behavior analysis. Chances are that there are other hosts competing in the same specialty area as you are. Do a research on how their target market behave, research their AUP, and define your hosting policy.

More often than not, a potential customer is likely to see someone cribbing about your company before he sees something good about you, and more often than not, such flames are posted by those who test the limits of acceptable usage of your service. When trouble starts brewing, if you can show the perpetrator that you have proof of abuse which violated the agreed terms of service, such individuals refrain from posting flames for fear of loosing face.

A well defined and comprehensive AUP will help you save time in making decisions, and enable you to defend your reputation against online flames.

Set your mind on constant progress
Establish company performance metrics, and do regular reviews. Determine what are the measurable points in each department of your company in which you want to see progress. Set targets for the long term, medium term and short term. Follow through rigorously, and make sure that you are making progress. Eg: “Support response time”, “Sales conversions percentage”, “Service uptime percentage”, “Customer satisfaction percentage”.

One important metric is your flexibility in adapting to the market. Sales queries and market trends should be monitored to see what customers are asking for, and your change management protocols should be initiated once you know the market it changing. Eg: “Raise of Ruby-on-Rails demand”.

Once you get into the habit of monitoring and improving metrics, your high performance metrics can even be a marketing edge against your competition. Eg: “Average resolution time”, “Satisfaction index”

Build a community around your brand
Encourage your customers to build their dreams along with yours’. When you help people build their dreams, you earn brand loyalty. It isn’t just good business, its also good karma.

(a) Establish a mailing list which will send in major updates of your business, and how they can gain from it. Invite feedback, negative or positive.
(b) Share your passion for a better internet with your clients. Post regularly your views and efforts on how you are making things better. Encourage them to visit your forums, Facebook, blogs, etc to share their experience. Invite them to present their ideas on how to improve things. Follow-up on that.
(c) Encourage people asking questions in forums, and if you think the solution can be applicable to all, post the solution there itself. You can divert complex issues to the support desk. Encourage culture of mutual help where one user helps another.

I have listed the qualities as per the priority of impact. Yes, attaining all the above is a tall order. But once you set your mind to this plan, and slowly hack away at it, before you realize it, you would be one of the top shared hosts.
