Shared Hosting - Is It Good For Drupal?

2011-08-11T18:36:00.000-07:00

Currently Drupal is one of the best CMS(Content Management System) that can be found on the net. With time many modules have been created for drupal and they all can be downloaded at Drupal’s main site.

Cheap shared web hosting is the perfect choice for those who are new to Drupal or want to set up a web site for their small business. Cheaper web hosting today tends to have good reliability, but disk space and bandwidth are often more restricted than with more costly hosting packages.

Before starting any site in Drupal be sure that you have found the best web host that will suite your needs. After you are finished configuring your site, having to move from one host to another is very time consuming task. If you have media rich site, you will have to move a lot of support files from the old host to the new one. This is time consuming job. Is very common when you finish moving your site something is not working after you have finished moving your files. If your website earns revenue then your business will be effected.

There are some factors you need to consider before going online:

1. Bandwidth – if you have a lot of visitors to your site then you should chose plan with unlimited bandwidth. If you get over your limit you site will be suspended for that month of you will be charged extra money.

2. Cost – For cheap Drupal hosting you want a good value package. US$5 each month is considered cheap.

3. Number of Domains – how many domain are you allowed to install with that package. If you have lots of websites on your account you should get an package with unlimited domains.

4. Limit of databases – if you have lots of domains will need a similar amount of databases. Consider that many Drupal websites have many database per website.

5. Disk Storage – Is enough storage provided to deal with your current website? Will it be enough for the future of the web site? Expect to get unlimited disk space, which in effect equals 1,000 GB, gigabytes of storage.

Drupal has a multisite feature that will allow you to run multiple sites from one installation. This is very useful if you plan to run many web sites from one single account. If you update a module or theme in the installation each of the websites running on the installation will benefit from the update. This is way maintenance of the files is less time consuming. Even the cheap hosting hosts allow you to run multiple websites from a single account.

All cheap Drupal hosting hosts will configure their hosting on shared computers. These shared servers run multiple accounts on a single computer. Your site will sit together will many other account that have purchased shared hosting too. They will share the same resources. This way the price form hosting is much more lower then dedicated hosting. The disadvantage is that the other peoples sites will disturb the performance of your site. As a general rule you can comfortably run Drupal websites expecting 1,000 unique visitors per day. If your site will have more visitors that this number then the best thing for you is to buy dedicated server.

Shared hosting if very cheap and you can hosting your site for prices lower then US$4. Check this arvixe coupons for cheaper hosting with Arvixe or this godaddy coupon for cheap Drupal hosting.

Web Design Principles

2011-08-11T18:32:00.000-07:00

Wondering why some online businesses and company websites can rapidly attract prospects and also make substantial earnings? It is mainly because they generally think of what their users would really like and add it to their website design. So if you want to get a profitable website, you should create a web site design that truly suits your guests’ preferences. Read the tips below and discover how to give your visitors a better online experience and become successful at your online business.

Offer Exclusive and Relevant Information. Probably the most essential things that buyers look for in a website is good content. If these people can’t find the information they require, they will simply get out of your website and rapidly lose interest in your products and services. That is precisely why you should always provide unique and high quality content material that will really keep them hooked. If your visitors are pleased with the information they’ve read, they will wish to buy from your website and perhaps recommend you to other people.

Be Consistent and Proper. If you’d like people to take you very seriously, then focus on developing a web site that tends to make your business look more professional. Choose colors and print styles that match your logo design, use a light background along with a dark text color, and make sure your blog posts are very well-organized. Also, try to be consistent with your web design by following the exact same format for all your website pages.

Make Your Site Compatible with All Web Browsers. Take note that your visitors aren’t using the same internet browsers, and if you do not deal with this issue, you’ll immediately be making them go away. You should make your website accessible to everyone to ensure that more folks will hear of your awesome products. Proceed and then consult an IT professional to double check your web site’s compatibility so you won’t be limiting your amount of guests and potential clients.

Tone Down the Visual Effects. Website designs that have some blinking graphics, flashing pictures or simply too much coloring will never be appealing for your users – simply stick to a simpler layout that users can easily browse through. Flash animations and JavaScript coding should really be avoided too mainly because they require a lot of loading time, and users don’t have a lot of patience for that. The more professional and organized your website design is, the more impressed and satisfied your customers will be.

What Do We Use Computer Programs For?

2011-08-07T16:26:00.001-07:00

There isn’t much of a distinction between our reliance on computer programs and our reliance on computers themselves. Programs are the instructions with which a computer runs, and without them you wouldn’t have computing. There is an argument for whether we have gone down a path with programming in which we’ve chosen a ‘language’ that isn’t as efficient that it could be, but the amount of ways we can use the programs we have are staggering.

Have you thought of how money transactions are carried out these days? You may think that there is still something to be said for physical money, but regardless of your aesthetic notions you’ll find that any transaction you make in the UK today will come into contact with a computer program somewhere down the line. Business depends on it and because of the immediate nature of transactions, business benefits from it too.

Electronic communications these days are all interfaced through computers at some level. Programs are what allow us to run all of the complex tasks that a mobile phone performs, whether that’s the seemingly simple act of a letter appearing on the screen when you’re texting, or the mysterious world of what happens after you press send. The internet itself is all programs: a network of networks, all of which are themselves a complex web of codes.

Website Design: How To Reconstruct A Poorly Performing Website

2011-08-07T16:16:00.000-07:00

It is not necessary to know everything there is to know about web design, and you can still create terrific sites as a non-professional. However today we want to highlight the typical kinds of web design errors you can easily spot around the net. If you want to see how promotions using this type of marketing can rank then check out Instant Affiliate Paydays Review.

We have seen some uses of Flash that is super nice looking, however the only problem is it presents too many problems all around. The thing about using Flash is it is not supported well by all user computers and it just drags everything down. If you have ever been at a site that has flash and waited and waited for everything to happen, then you know exactly what we are talking about. Of course, there are valid applications for flash, but you have to optimize properly and make sure it does not adversely impact browser load times, etc. If you really do want to use flash and have no other choice, then make sure you have a static HTML page alternative too, so that the visitors who want to avoid flash can do so. It is amazing at how easily things can be improved when examining Mobile Affiliate Profits Bonus. There are some reasons why you it would be a good idea to cloak your links, and so let’s talk about that now. Sure, there are reasons why you may want to do this, and it just depends on what you are doing. Usually affiliate marketing is the area where you will find this done the most. Practices like commission theft have always been present, and there is no totally iron clad way to protect your links. Besides having clear and effective anchor text on links, you should also see to it that they are clearly visible. Ensure that all the links on your site have a contrasting color, and if possible make your links underlined. This is not really about being dishonest by hiding something, but in the end you have to make the decision.

Ever visited a site that takes forever to let you inside? Have you ever had to overcome a Flash page or Flash ad intro before you could get into a site? What you will discover is most people just turn around and go where they came from when they encounter this. It is just that people are generally in a hurry, and also this practice can be mistaken for an ad. If you really do want to give information about yourself or your company, you can do it on the ‘About Us’ page, where it’s more appropriate. That’s the reason projects on Seonuking have changed the way in which we think about things today. While some issues are not directly about site design and mistakes, they are related to the overall user experience and are important.

Waiting Patiently To Be Enchanted ...

2011-03-10T20:23:00.000-08:00

I have high hopes and still waiting for one of the most anticipated birthday gifts I could give myself, Enchantment: The Art of Changing Hearts, Minds, and Actions written by one of my favorite authors Guy Kawasaki. I've read the awesomeness that is The art of the start which been one of the most influential publications I have seen in a long time.

The golden key to distributed computing is ... Spades & C-CAPS Part 1.

2011-02-20T17:43:00.000-08:00

The art of engineering the seemingly outrageously complex logistics behind our modern distributed computing techniques have been manipulated over the years now. It appears no matter how the shape forms, it still forms into the same shape. The current paths in which we've taken to adhere to the abstract image of "true distributed computing" has been one of repetitious erroneousness. As my mom always said, "the apple doesn't seem to fall far from the tree". Over the past few years I've invested my leisure time to investigating many cloud computing paradigms, the story I've been hearing over and over, time and time again had began to uncover a few analogies constructing in my head that I've been able to apply to a new lightweight concept.

The concept surrounds the "dealer" idea behind the 1930's card game ... Spades, which I'll touch more on a bit later but let's get more familiar with what concepts we have available now. The problem with current distributed computing has forced the developer to sacrifice one principle for the other two.

Consistency means that each client always has the same view of the data.
Availability means that all clients can always read and write.
Partition tolerance means that the system works well across physical network partitions.

In compliance with the CAP Theorem, you are forced to select only two. Seems a bit unfortunate as all permutations of those principles lead to what I call the "Hope Diamond". You see, the Theorem starts off as a simple triangle

After this triangle shape is formed as stated above, you're forced to select two. What if you wanted all three? What if you wanted your cake and wanted to eat is also? turns out you can, but now that you have the cake ... are you going to eat it with a fork or spoon?

The "Hope Diamond" requires two more points within this dimension, let's move to the forth point. Now that you have your consistency, availability and partition tolerance you'll need to choose between the fork and spoon. Will you choose the "CPU"(the processing layer/point) to distribute the processing and leave the data centralized to avoid moving massive amounts of data. This concept will leave your solution within an Tier'd approach only scalable via the extension of the data processing layer "CPU".

Now let's discuss the fifth point or ... the STORAGE(the data layer/point). Distributing the Storage layer gives you the ability to abstractly guarantee yourself both Availability and Partition tolerance .. Right?, well let's take a mental look at our "Hope Diamond". Our diamond is actually a pyramid without the fifth point, CPU is always the top point of this pyramid before the pyramid becomes a diamond, our bid to distribute processing power has led us to forget and sometimes ignore the fifth point(STORAGE) and vise versa.

The only way to have true CAP is to apply the theorem to both 4th(processing) 5th(storage) layers equally with ABSOLUTELY NO compensations on either aspect, regardless to your business process' requirements.

So... , where does the card game 'Spades' come in?

.... to be continued.

Quick Outlook AutoComplete .nk2 Hack From OutlookTip.com ..and then some

2011-02-08T08:39:00.000-08:00

While scouring the web for some quick hack to fix my auto-complete within outlook I ran across this little beauty

http://goo.gl/fAKkn

I recommend only building the cache on trusted folders on sent folder, if you rebuild on Inbox you basicaly making a cache of inbound emails wich could contain alot of spam.

"Learn how to create a new profile and use your existing data store with it (Importing pst is BAD!). If you rebuild your computer often or use multiple computers, you use the Custom Installation wizard to create an Outlook Profile file (*.PRF) to help you recreate your profile easily. You can even edit the *.prf files using Notepad to add new accounts:Adding Internet Mail accounts to a PRF. "

The site provides a pretty well outlined arsenal of tutorials and hacks to get the most out of Outlook.

"For those using an older version of Outlook and missing the holidays for 2008 and beyond, you’ll need to download one of the updated holidays files from Missing Holidays. Those who upgraded from an older version to Outlook 2007 just need to add the updated holidays included in Outlook 2007 using Tools, Options, Calendar Options, Add Holidays."

I've honestly never used outlook's calender to realize it was actually missing holidays, go figure.

Social networking – is everyone doing it?

2010-12-12T19:39:00.000-08:00

According to recent research commissioned by Intuit UK, one of the leading provider of accounting software for small business, over half (54%) of UK small business owners are already using social media to market their company – and 35% of these said they posted updates on a daily basis. But is social media right for every small business? If you’re considering taking the plunge into an online network, here are some of the factors you might need to think about:

1. Choosing your channel

According to the research, almost three quarters of the companies experimenting with social media claimed they used LinkedIn the most (73%), compared to Facebook (64%) and Twitter (63%). Before setting up multiple accounts that might go unused or worse, unnoticed, it’s important to understand who your target audience is and where they are currently interacting.

2. Being clear and consistent

Social networks can be an important channel to raise brand awareness and even gain new customers, so it’s essential to be clear and consistent with what you say online. But remember, social media is about interacting as a person not a brand, so don’t be afraid to be yourself!

3. Complementing the ‘old’ with the ‘new’

Remember that social media does not exist in isolation. Have a look at your existing marketing activities and think about how social media can be used to enhance or complement them. For example, social networks can be a great forum to gather feedback on both products and industry issues, which can be used to support market research projects.

4. Listening!

Online communities are about two-way conversation, not just selling. It’s important to listen and respond to feedback, and offer help and advice - don’t simply push out sales messages. In the long term, having real conversations with your customers is more likely to gain you their respect and loyalty.

If you think we’ve missed a trick or two, please share your experiences and top tips for using social media in the comments section below.

Dell and HP are one of the most popular technology companies in the world. Both these companies have made a name for themselves in the realm of desktops, laptops, scanners, printers and other peripheral devices, besides providing IT services as well.

Create AJAX Application Using JSON and Servlets

Create AJAX Application Using JSON and Servlets

By: Alexander Zagniotov

In this article I would like to show how JSON (JavaScript Object Notation) and Java servlet can be used together in a little AJAX (Asynchronous JavaScript and XML) application.

To give brief description to those who are not closely familiar with JSON -

JSON is a lightweight syntax for representing data, which makes working with it much more pleasant than with XML and makes AJAX applications faster. Also, when working with JSON, there is no need for an XML parsing.

In the following example, I am going to create a callback servlet that fetches and parses an RSS feed. Then the parsed feed data is passed to the client side in a form of JSON. The data then formatted and presented to the user. The client uses AJAX call to query the servlet.

For this application, I used three third-party libraries:

JSON library provided by JSON.org and extended by JSON-RPC-Java which allows to create and easily parse JSON data through Java code. This library can run in a Servlet container such as Tomcat, JBoss and other J2EE Application servers.
Project ROME
ROME is an set of open source Java tools for parsing, generating and publishing RSS and Atom feeds.
JDOM XML parser
JDOM is a Java-based "document object model" for XML files. JDOM serves the same purpose as DOM, but is easier to use

The libraries are included in the source code which accompanies this article. This application example is also included as a WAR archive, ready to be deployed on Tomcat.

The following is my servlet implementation. The servlet fetches and parses feed data. The JSON library mentioned previously allows me easily to create and populate JSON object.

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.json.JSONArray;
import org.json.JSONObject;

import com.sun.syndication.feed.synd.SyndEntry;
import com.sun.syndication.feed.synd.SyndFeed;
import com.sun.syndication.fetcher.FeedFetcher;
import com.sun.syndication.fetcher.FetcherException;
import com.sun.syndication.fetcher.impl.FeedFetcherCache;
import com.sun.syndication.fetcher.impl.HashMapFeedInfoCache;
import com.sun.syndication.fetcher.impl.HttpURLFeedFetcher;
import com.sun.syndication.io.FeedException;

}
}

As you can see it is very easy to construct JSON objects and arrays on the server side and pass them to the client. For the purpose of this example I am getting my data from RSS feed, but the data can also be coming from DB etc.

The following is my client implementation. The client queries the servlet using AJAX call. When an AJAX call returns a response from the servlet in a form of JSON object, the object data is formatted and information about the RSS feed is presented to the client:

< html >
< head >
< title >Java Beans dot Asia< / title >

< script language="JavaScript" type="text/javascript" >

var httpRequest = null;

function getDescriptionAsJSON() {
var description = document.getElementById('description');
description[removed] = "Loading, please wait ...";

var url = "h tt p:// localhost: 8080/json/json";
if(window.XMLHttpRequest){
httpRequest = new XMLHttpRequest();
} else if(window.ActiveXObject){
httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
}

httpRequest.open("GET", url, true);
httpRequest.onreadystatechange = handler;
httpRequest.send(null);
}

function handler() {
if (httpRequest.readyState == 4) {
if (httpRequest.status == 200) {
processJSON(httpRequest.responseText);
}
}
}

function processJSON(jsonObjectString) {

var description = document.getElementById('description');

//Since JSON is a subset of JavaScript, I am using
//JavaScript's own compiler to parse JSON in one line!

var jsonObject = eval('(' + jsonObjectString + ')')
var text = "";

text += "Author: " + jsonObject.author + "< br />";
text += "Blog Name: " + jsonObject.blogtitle + "< br />";
text += "Blog URL: " + jsonObject.bloglink + "< br />";
text += "Blog Description: " + jsonObject.blogdescription + "< br />";
text += "Blog Language: " + jsonObject.bloglanguage + "< br />";

description[removed] = text;
var entries = "Last " + jsonObject.blogentrytitles.length + " blog entries are:\n\n";

for (var index = 0; index < jsonObject.blogentrytitles.length; index ++) {
entries += (index + 1) + ": " + jsonObject.blogentrytitles[index] + "\n";
}
alert(entries);
}

< / script >

< body >
[some image]< br />< br />
< div id="description" >< /div >< br />< br />
< a href="[removed]void(0)" onclick="return getDescriptionAsJSON();" >Click to get description!< /a >

< / html >

As you could see, JSON data can be easily parsed on the client side with the help of Javascript eval() function. To remind - JSON is a subset of Javascript, therefore eval() will produce a valid object.

Keep in mind, that there is a need for extra care when using eval. The problem is that eval will compile and execute Javascript code that coming back from the response. This could cause a security risk if the response data is coming from an untrusted source.

That's it. I hope this example was clear and helpful :)

Please note that this example was tested by me and its working fine. The source code as mentioned previously is included as Eclipse project. You can simply create a new Java project from the existing Ant build.xml file.

Comments/flames are appreciated :)

Cheers

What is Cloud hosting?

By: Cloud Hosting

Cloud Hosting has been creating quite a buzz around these days. You might be hearing the phrase for the first time but the technology is not something new at this time of writing.

Cloud hosting is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid. It is also called cloud computing.

Cloud hosting is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The name cloud hosting/computing was inspired by the cloud symbol that's often used to represent the Internet in flowcharts and diagrams.

Benefits of cloud hosting

Cloud hosting benefit users from different prospective. Its scalability and cost efficient is the commonly known advantages.

As the technology is highly scalable (load balancing, hardware upgrades, etc), website expansion can be done with minimum limitations. Think about the hassle of migrating your website from a shared server to a dedicated server; think about server crash when your website experienced a sudden surge – all these problem can be avoided easily by switching to cloud hosting.

Cloud hosting companies charge their users based on the quantity of computing power consumed. It's like your electricity and water supply bills – its pay-per-use thus gone are the days where you need to reserve massive server powers to avoid website crash from sudden traffic surge.

Characteristics of cloud hosting

A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, usually by the minute or the hour; it is elastic -- a user can have as much or as little of a service as they want at any given time; and the service is fully managed by the provider (the consumer needs nothing but a personal computer and Internet access). Significant innovations in virtualization and distributed computing, as well as enhanced access to high-speed Internet and a weak economy, have accelerated concentration in cloud hosting.

Types of cloud hosting

A cloud can be private or public. A public cloud sells services to anyone on the Internet. A private cloud is a proprietary network or a data center that supplies hosted services to a limited number of people.

When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud. Private or public, the goal of cloud hosting is to provide easy, scalable access to computing resources and IT services.

Continued research on hadoop lead me to a quite interesting site(will link later) appearently the ‘Lustre distributed file system’ has been used as an alternative to hdfs, haven’t done any experiments yet but will update you soon..
