Let us find how these skills have created demand for employment globally.

The demand for cloud computing is growing at the rate of 61% annually. In many instances the job offer placed on various online sourcing platforms has to be extended beyond 44 days which is the average display time for any job. Cloud based technologies will move businesses to the next level. Hence deployment of cloud based technologies and personnel to look after to deal with cloud based technologies are need of the hour. There are companies like HP that have launched courses to train up candidates to fill this gap. It is also important to engage competent personnel so that the services will not be disturbed for businesses.

For businesses, cloud computing will cut down their expenditure and for users it will simplify their lives. The beauty of cloud computing is its offer to utilize services as and when required and in the amounts a business can utilize. Thus, for a business it is an attractive choice. As a matter of fact, cloud is a set of hardware, software, services, storage and interfaces. This total set offers integrated services to your enterprise virtually located somewhere and running on round the clock basis. Small businesses can cut down their cost as they cannot afford to manage dedicated infrastructure and man power to achieve a very high level of service that can be offered on round the clock basis.

Growing and big businesses also can manage these services offered by third parties by involving a team of professionals who will look after the deployment and management of cloud computing services. Businesses can save substantially as they can pay only to the volume of services they are utilizing and not on a fixed basis. The companies that are providing cloud based services should gain the trust of potential clients by being able to address various security and privacy issues.

As more and more awareness is created about cloud computing among the business community, the demand raised high for people possessed with these skills. It is apparent that there is a huge gap between the available number of cloud based positions and the competent personnel available in the market. The recent boom in this direction has added fuel to the fire. Recruitment of candidates for Cloud computing is a complex task as the requirements change from one business to another business and from one location to another location.

The skills are expected not only from IT experts but also from professionals from other domains such as customer support, sales and marketing. In fact, the demand for candidates possessing cloud computing skills is more from other than IT domain. In spite of all around efforts to recruit through various online and offline sources, the gap may still widen as the requirement of professionals is increasing at 70% every year. As an alternative, companies may come up to the point of recruiting and training them up as per their requirements.

Hackers are tech savvy people of highest degree. They know the ways and means to deploy new technologies and tinker with existing technologies. Therefore these are highly knowledgeable people who are not exposed to the society as happens with technology experts working in major software development companies or authorities who decide the modalities to work with various technologies. There are two types of hackers. They are ethical and non-ethical. Ethical hackers will not intrude into the private space of individuals or companies. They will not try to steal other’s information or control and monitor your activities in computer or network.

Ethical hackers contribute to the society in developing protection software such as anti-virus, anti-spam, etc. They have all the technology in their hands to run a parallel network much in the lines of internet. Non-ethical hackers work against the interests of public and they are involved in to fraudulent activities. It is similar to physical encroachment of private space of others or stealing. In fact, they are a menace to society. SOPA will be detrimental to the activities of both ethical and non-ethical hackers. Hence, hackers’ world has serious plans to run their own networks. In this connection, they are planning to go to the extent of launching their own satellites. One of the options explored by hackers is to launch satellites through balloons into earth’s low altitudes. Aviation experts rule out the possibility of achieving the launching effect without using a rocket which gives the main thrust for the body to be injected into earth’s object so that it will continue to rotate in the designated orbit.

There is widespread criticism on SOPA not only among hackers but also among the interest user communities. For the most, SOPA seems to be influenced and reflected by film producing industry’s lobbyists. The measures that are going to be introduced are more to protect the interests of recording companies. There are number of acts to safeguard the copyrights of audio and video recordings. In fact, they can strengthen those acts if they are any loopholes or practical difficulties in their implementation as per the change in technologies in usage and distribution of recordings.

SOPA should not limit the fundamental rights of citizens i.e., freedom in every sphere. Those who are involved in producing the draft and implementation should have the fresh blood of internet and changing technologies so that the act will include and protect the interests of millions of people across the globe. If not, those who want freedom to the maximum potential extent may explore alternative ways making them go to the extent of launching their own satellites, protocols and standards and be able continue to enjoy their freedom in a different way.

What are your thoughts?

UK newspaper, The Register sources close to Microsoft, this week confirmed the rumors that circulated during the month of June where customer’s data were being striped between the pair. By the process of striping, the data accessing speed is increased and there is no need to rely on a single device or service. Sources say, that, in order to reduce the risk of depending on one single supplier, Apple has selected two providers since it already suffered from unpleasant online services from a single external service provider. It has to be noted that the level of maturity and services differ a lot when a comparison is done between Amazon and Microsoft.

A cost of approximately $1 billion would be required to build the infrastructure of cloud services. At present, Apple doesn’t have a bunch of high speed and high density servers. However, with a massive data center under construction in North Carolina, that is worth $500 million, a part of the cloud service could be taken over here. Still it surprises me, why Amazon and Microsoft are apparently mum on this subject.

In the present scenario, Apple’s technology is not well suited for a cloud type system. It is flexibility and provisioning that separates ‘Cloud’ from a just of bunch of servers. For instance, if you take a normal server host, you can get a server in a fairly short order, in case you need a bunch, you’ll have to wait for some time till the hardwares are ordered and you have to pay regardless of usage. With Amazon’s Elastic Cloud server is available in minutes and you have the option to pay more based on usage since idle resources don’t have to take up resources. Now, this is possible because it is all virtual.

They may even fix it since there was a time when they liked AIX or they may even build a data centre with someone else`s technology. This will take a lot of time and only Microsoft and Amazon are the big ones which can deliver it. So, this can be a reason for them to use Microsoft and Amazon.

Another possibility is that using AWS and Azure, they can develop a CDN (content-delivery network) since it has already used Akamai and Limelight as CDN’s in the past. This allows developers to deliver high-bandwidth content more quickly and efficiently by placing delivery points closer to users; this will essentially speed up all sorts of data transfer that go through their CDN.

When Microsoft was questioned regarding this, they replied stating that they don’t reveal the customer details. But, when it comes to ‘Cloud’ privacy is always in question. Sometimes, it baffles me where I think that since Apple runs on beta version currently and the service appears to only run in iMessage on Azure; is Apple still deciding its host platform?

Let us know, if you think differently.

Lots more Input Types

HTML5 brings a lot more input types into form elements to give a richer user experience, of which some are text, url, telephone, email, range, color, date & time pickers. Some of these are helpful in the new validation feature, which I’ll go into detail in the next article in this series, and also improve usability on mobile devices. For example when an input field is marked as telephone in a form, when a mobile user selects that field for input, automatically he is shown a number pad to enter the text. The users also may get different keyboard layouts for the email and URL types of input fields as well.

Range

You can have the user select a value using a slider with the range input type. The image above shows how this renders in Google Chrome. The actual rendering of this may differ from browser to browser. The attributes of this input type are pretty self explanatory.

<input type="range" min=10 max=60 step=3 value=15>

Date and Time

HTML5 also provides date and time pickers. Opera implements this feature well. Here’s how Opera renders the a datetime picker

<input type="datetime" >

You can also configure this selection field to just show a date picker, month & year, week or just time. Here are the different options:

<input type="date">
<input type="month">
<input type="week">
<input type="time">

Spin those Numbers

You can use the number input type as a form field and convert a text box into a spinner, which the user can use to input data by just using the spinner. You can specify the minimum, maximum, step and the default value for this input type.

<input type="number" min="0" max="100" step="5" value="15">

New Attributes for Form Fields

Apart from input types, HTML5 also provides additional attributes for existing input fields. Here are some of the new and interesting attributes for form fields:

Place Holder

This is something we all have used Javascript so far to implement in forms. To have a text explaning the input box appear and dissapear when the user selects it to start typing. You can now achieve this by adding an attribute called placeholder into the input tag.

<label>Username <input name="uname" type="text"
         placeholder="Enter your Username"> </label>

Focus & Autofocus

No javascript required here – If you want to focus on a particular form field in HTML5 just add the attribute autofocus to that input field:

<label>Username:
<input name="uname"  type="text" autofocus>
</label>

Remember that using autofocus along with placeholder may not work well, since the placeholder text dissapears when the focus is on that field

Tip: Even though not purely HTML5, wrapping the label and input field in the <label> tag allows the user to even click on the label text to focus on field. If you can’t enclose the input field within the label tag, you can also use the for attribute pointing to the input’s id you had defined like so

<label for="usernamefield">Your Name</label>
<input name="uname" id="usernamefield">

DataList

How about about a Google Suggest like function without Javascript like the one above? (Try this in Opera) -

<label> Select Site:
<input name="site" id="site" type="url" list="site_list" >
<datalist id="site_list">
<option value="http://blogs.vinuthomas.com" label="VT's Tech Blog">
<option value="http://www.mynokiaworld.com" label="My Nokia World">
<option value="http://myandroidworld.in" label="My Android World">
</datalist> </label>

Multiple Selection

This attribute allows the input field to select multiple items from a datalist or in the example below, a file list. HTML4 allowed only one file to be selected using the file input type, here’s how to enable multiple files in HTML5

<input type="file" name="uploadfiles" multiple="multiple" />

Progress and Meter tags

HTML5 brings two ways to show progress or percentage bars without any external javascript or server-side library. You can use the progress tag with the maximum value in the max attribute and the current value in the value attribute

<progress id="prog" max=100 value=33>33%</progress>

In Google Chrome, this renders as:

You can also achieve something similar to this using the meter tag:

<meter min=0 max=100 value=22 optimum=100>22</meter>

This shows up like this on Google Chrome:

Here you can play around with the optimum attribute which changes the rendering a bit. If you set the optimum to be equal to the max value, if the you try rendering anything less than the max, the filled up portion of the bar is colored yellow instead of the usual green.

If you’ve tried the above examples in various browsers, you’ll have noticed that none of them currently implement all of these perfectly. But with the HTML5 draft nearing finalization and various browser developers working on implementing the new features, we should soon see easier web-development cycle. I just hope we don’t have to go through the old-style hacks to get these working like in the old days.

Look out for the next in the HTML5 series where you can learn about form validation on the browser without writing javascript.

HTML5 source code

If you’ve been hearing about the buzz about HTML5 and what it is – here’s a brief post and ways to get to know HTML5 better.

HTML5 is the latest version which newer HTML and XHTML documents should confirm with. This version of HTML aims at simplifying and overcome issues with the older HTML4 presented.

The first thing you’ll notice in HTML5 is that the HTML declaration itself is simplified. To declare a HTML document, all you need to do is to declare the document in this way:

< !DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>Sample HTML5 Document</title>
</meta></head>
<body>
This is my first HTML5 document
</body>
</html>

You’ll notice that the standard DOCTYPE declaration which is required in HTML4 is missing here. This is the first in many simplifications which eases up development in HTML5.

There’s simplifications on other tags also. For example HTML5 features a <video> tag which makes it easy to embed videos in your page, without any third party plugins, as simple as this:

 <video src="mymovie.webm" controls>
If you are seeing this, your browser may not be fully HTML5 compliant.
</video> 

There’s still debate about what the default format for HTML5 videos should be, Google in the meanwhile has introduced the WebM format which royalty-free high quality video compression codec for use on the web. This format has eventually gotten the support of Mozilla, Apple, Opera and Google. The newer nightly builds of Firefox and Chrome support this format.

If you are looking at exploring the differences between HTML4 and HTML5, this links should be of help – HTML5 differences from HTML4. Another very useful site for developers who are new to HTML5 is Dive into HTML5. The author of this site explains the basics of HTML5, what’s new with it and how to do stuff with it in a simple way.

To get you started on HTML5, here’s a screencast by Addy Osmani which takes you through the basics in under 5 minutes.

Even though the HTML5 specs are still evolving, and browser support for the new features may time sometime to stabilize, the power of HTML5 is the way to go. The first uses of HTML5 is going to be what is powering the mobile web, since most Smartphones these days are running Webkit browsers which are HTML5 compliant.

I’ll be taking a deeper look into HTML5 in the future posts, so look in the HTML5 section here for updates. Here are the links from this article for your reference:

Here’s something in the making, a PHP extension which caches MySQL queries irrespective of the extension being used. It’s a plugin for mysqlnd, the native MySQL driver for PHP called  mysqlnd_qc. This currently requires PHP 5.3.3-dev which is still in development.

The extension allows caching buffered queries through mysql_query and mysqli_query. It allows cache-invalidation though TTL or a user defined callback. This extension is still in the protoype stage right now and will evolve as the project progresses.

The Query Cache is implemented as a PHP extension. It is written in C and operates “under the hood” of PHP. During the start up of the PHP interpreter it gets registered as a mysqlnd plugin to replaces selected mysqlnd methods.

At PHP run time it proxies queries send from mysqlnd/PHP to the MySQL server. If a query string starts with the SQL hint (/*qc=on*/) to enable caching of it and the query is not cached (Cache miss), the query cache plugin will record the raw wire protocol data send from MySQL to PHP to answer the query. The query cache records the wire protocol data in its cache medium and replays it, if still valid, on a cache hit.

Note that the query cache does not hold decoded result sets consisting of zvals (C struct representing a PHP variable). It stores the raw wire data of the MySQL client server protocol. In case of a cache hits, mysqlnd still needs to decode the cached raw wire data into PHP variables before passing the result to the user space. This approach has one major advantage: simplicity.

You can get more information and installation instructions over at the MySQLND Query Cache Project page at Mysql Forge.

• Detects Cross Site Scripting attacks (XSS)
• Detects Hidden Directories and Backup Files
• Looks for Known Security Vulnerabilities
• Searches for SQL Injection Vulnerabilities
• Automatically detects zero day bugs
• Performs Website Fingerprinting

Once the service finishes scanning your site for issues and vulnerabilities, it emails you a PDF with what they found for your site.

In order to prevent sensitive security reports like this going out to others, ZeroDay scan asks you to add a text file with some security text to be added to your site. This ensures you can scan only sites which you have control over.

This project is still quite new and their documentation is down to the bare minimum. They do have the required documentation for you you’ll need to get your hands dirty with FRAPI. First you’ll have to download the sources and set it up on your own. One you’ve downloaded the files and setup the directory permissions, you’ll also have to make the Apache Virtual host settings to get FRAPI to start working.

FRAPI has the following requirements for it to run:

• PHP 5.2.2 or later
• APC: Required for caching of actions, errors, etc.
• HTTP: (http://pecl.php.net/pecl_http
• PEAR: (http://pear.php.net)
• PEAR::HTTP_Request2: This could be replaced by pecl_http however it is used in the bundled ArmChair package which is used to access CouchDB (http://pear.php.net/HTTP_Request2)

Some of the advantages I see after playing around with FRAPI is that it auto-generates the code skeleton for you to work on so you just have to go fill in the blanks to create your service. You also don’t have to worry about transfoming the your data into different formats, FRAPI supports JSON, XML, PHP, and plain text natively. This enables you to make your webservices cross-platform and even power mobile apps. You also don’t have to tweak around with code which handles http requests and responses while creating your webservices.

For more information on this project, head over to their site  getfrapi.com or their project page on github.

What if you could actually check the server load in your PHP application? Would you think about checking the server load before doing some heavy computational task or database accesses? There’s function in PHP which will allow you to check the load averages on a server.

The sys_getloadavg() in PHP gives you the load averages for your server. You can use this to check the load on your server before processing a request.

$serverload = sys_getloadavg();
print_r($serverload);

The code above gives the output:

Array
(
    [0] => 1.07
    [1] => 0.89
    [2] => 1
)

The output from the code shows the system load averages where [0] is the load averages for the past 1 minute, [1] is for the past 5 minutes and [2] is for the past 15 minutes.

On an ideal server, the load averages on the server shouldn’t go above 3. A load average of more than 15 would mean that the server is already running much lower than normal, and you may not want to add more load to this.

You can use this output to decide whether to serve a process intensive page depending on the server load. Here’s a pseudo-code on how you’d do something like this:

$serverload = sys_getloadavg();
if ($serverload[0]<10)
  {
    // process loads of data now
    some_big_process();
  } else
     {   // Send a 503 header stating that the server is overloaded.
         header('HTTP/1.1 503 Too busy, try again later');
         die('The server is busy at present and cannot process your request.');
      }

You can also run the application in such a way that you can wait till the load on the server decreases to run your process. This is useful if you are running a cron for processing data:

set_time_limit(0);
//set time limit to 0, so PHP's max execution time doesn't interfere with the processing script
$serverload = sys_getloadavg();
//Check load and see if it's low enough to start processing
while ($serverload[0]>5)
{  //Wait for 1 minute to check load again
    sleep(60);
}
// out of the loop - so let's do some processing now!
some_big_process();

To ensure that the script doesn’t run endlessly on a permanently overloaded server, time check in the while loop to auto-end the script it the server load remains high for a certain amount of time.

Google has released a Web Application Security Scanner over at Google Code. This can be used to scan you site for possible security issues which might be lurking around. Skipfish prepares an interactive site-map for the targeted site by carrying out a recursive crawl and dictionary-based probes.

This scanner is easy to setup on an Ubuntu machine. You’ll need to have the packages for gcc and make installed on your system in order to compile Skipfish from it’s sources. Once you install these, download the Skipfish package from the project download page. Once you download it, unzip the files to a folder of it’s own and head over to that folder in your terminal window and issue a make command by just entering this in the terminal.

make

After the package compiles you can test to see if it was successful by issuing the following command in the terminal

./skipfish -h

This should show you a the Skipfish help screen. If you don’t get that, check the make output to see if there were any errors during the compile process.

Once you get Skipfish compiled and ready on your system, head over to their documentation pages to learn more on how to use this to tool to scan your site.

This tool creates a html report of the scan in the output directory you specify and the output looks like this:

Skipfish has a highly optimized HTTP handling which allows you to achieve up to 2000 requests per second on servers which can take that load. It also doesn’t depend on the technology you use to host and build your web application.

If you’re interested in what types of scans are currently implemented on this tool, here’s what it supports (from their documentation page):

• High risk flaws (potentially leading to system compromise):
  • Server-side SQL injection (including blind vectors, numerical parameters).
  • Explicit SQL-like syntax in GET or POST parameters.
  • Server-side shell command injection (including blind vectors).
  • Server-side XML / XPath injection (including blind vectors).
  • Format string vulnerabilities.
  • Integer overflow vulnerabilities.

• Medium risk flaws (potentially leading to data compromise)
  • Stored and reflected XSS vectors in document body (minimal JS XSS support present).
  • Stored and reflected XSS vectors via HTTP redirects.
  • Stored and reflected XSS vectors via HTTP header splitting.
  • Directory traversal (including constrained vectors).
  • Assorted file POIs (server-side sources, configs, etc).
  • Attacker-supplied script and CSS inclusion vectors (stored and reflected).
  • External untrusted script and CSS inclusion vectors.
  • Mixed content problems on script and CSS resources (optional).
  • Incorrect or missing MIME types on renderables.
  • Generic MIME types on renderables.
  • Incorrect or missing charsets on renderables.
  • Conflicting MIME / charset info on renderables.
  • Bad caching directives on cookie setting responses.

• Low risk issues (limited impact or low specificity):
  • Directory listing bypass vectors.
  • Redirection to attacker-supplied URLs (stored and reflected).
  • Attacker-supplied embedded content (stored and reflected).
  • External untrusted embedded content.
  • Mixed content on non-scriptable subresources (optional).
  • HTTP credentials in URLs.
  • Expired or not-yet-valid SSL certificates.
  • HTML forms with no XSRF protection.
  • Self-signed SSL certificates.
  • SSL certificate host name mismatches.
  • Bad caching directives on less sensitive content.

• Internal warnings:
  • Failed resource fetch attempts.
  • Exceeded crawl limits.
  • Failed 404 behavior checks.
  • IPS filtering detected.
  • Unexpected response variations.
  • Seemingly misclassified crawl nodes.

• Non-specific informational entries:
  • General SSL certificate information.
  • Significantly changing HTTP cookies.
  • Changing Server, Via, or X-... headers.
  • New 404 signatures.
  • Resources that cannot be accessed.
  • Resources requiring HTTP authentication.
