5 Ways To Protect Yourself Online

Much has been made in recent years about the fact that more and more people are living their lives increasingly through the Internet. Most specifically, many different businesses and industries are operating more on the Internet, in many cases lending employees more freedom and flexibility with work hours and locations. But despite the convenience that comes with increased Internet reliance, there are also increasingly more concerns with regard to Internet security. The simple fact is, when we spend so much time online, we inevitably expose aspects of our personal lives to the world at large. So, here are 5 tips for how to protect your personal identity and information online.

1. Approach Social Media With Caution

It’s no secret that popular social media sites like Facebook have severe security concerns. The people behind various social media platforms have been accused of storing and mining for personal information, and there’s simply no denying that creating social media profiles “puts you out there” in a somewhat vulnerable fashion. In today’s world, it’s tough to avoid social media completely. But by reading privacy policies carefully and adjusting security preferences accordingly, you can at least be as safe as possible while partaking.

2. Avoid Storing Passwords

There are many instances when a website asks you to store personal information, passwords, and even shipping and payment details. For example, when you order something from Amazon, or subscribe to a publication, etc., you will often have the option of storing your account information for easy access in the future. This, however, not only leaves that personal information available on those sites for hackers to potentially locate, but it also leaves you vulnerable should your computer be stolen or lost. Try to avoid storing information for these reasons.

3. Use Secure File Sharing

Secure file sharing is still an expanding and improving industry, but offers a number of significant Internet security benefits. For example, Sharefile services allow you to send email files with encryption, and to protect your file sharing accounts via passwords. This simply keeps your communications more secure.

4. Use Cloud Storage

Similar to secure file sharing, cloud storage can help to keep your communications and file storage secure. Essentially, when you use a cloud computing provider, you are able to save data on the Internet, in a professionally secured cloud service, as opposed to physically on your devices.

5. Protect Your Devices

Finally, with more activity being conducted online, many of us have a great deal of sensitive data stored on our computers, tablets, and even mobile phones. For this reason, physical protection of such devices is just as important as digital security. From protective cases, to password access, it’s important for you to attempt to prevent damage, theft, or unauthorized usage of your devices.

Best apps for the Nokia Lumia

Nokia Lumia is beloved by many for its smart, colourful looks and its stylish live tiles homepage. If you have one of the Nokia Lumia phones, you will already have a number of apps as they come preloaded with some very useful ones. There is the integrated Drive sat nav and a maps location tool. The Nokia Music app is one of the best.

The innovative City Lens allows you to find out a lot more about the location you are in. Just by holding the phone up and pointing it at your surroundings it will tell you what shops and restaurants and other businesses and places of interest are nearby. By tapping on one of the businesses you can read reviews, get directions and find links to relevant websites. It is an equally useful tool for finding out about a place you are planning to visit. Just load that area on Microsoft Bing maps and City Lens will tell you all about it. Once you have had your phone for a day or two though and played with the preloaded apps you will want to add some extras. Which are the best ones around?

BBc iPlayer

It has been a long wait for Windows phone users but finally the BBC has produced a version of iPlayer for them. There is the full seven day archive of programmes, radio playback and 3G streaming. You do have to have Windows Phone 8 though so those with older phones will continue to miss out. Time to sell your old Nokia phone and update to a new one maybe?

Lomogram

Instagram for android phones has cornered the market for photography apps. It is not available for the Windows phone, however, but do not despair. Lomogram does just the same. You can choose from lots of different filters, frames and lighting effects and then upload your masterpieces onto Facebook and Twitter with ease.

BT Wi-Fi

If you are a BT subscriber and download this app, your phone will automatically connect to free Wi-Fi hotspots wherever you are. No passwords, no costs, just free internet, instantly.

Runtastic

Runtastic is a sports tracker that uses GPS to estimate how many calories you have used during your run, your average speed and your distance. GPS only works if you are on the move, of course and so for those who are working out in a gym, there is the option of adding times and distances manually. The app comes with a live tile for your home page which will always take you speedily to your monthly stats: a great motivator.

Battery

Using the live tiles homepage to great advantage, Battery is a great app for those who want to eke out more life from their phone’s battery charge as well as for those number fans, who love statistics. By touching one of the Battery icons you can find out when you last charged your phone, how much charge you have left and how long it will last. The Longest Battery Life Time option is an easy and efficient way to extend your phone use time.

Locate Java Home on Mac OS

I am using Mac OS X 10.5 and I installed java 7 on it today. But the funny thing was I was unable to locate the directory where I have installed my Java. Finally I found it out and here are the steps :

  1. Make Sure you have Java installed properly. For that open your terminal and type which java. If you have JDK installed your machine, you will get /user/bin/java. This shows that you have JDK and you are safe to search for Java home on your MAC. Otherwise install JDK again on your Mac.
  2. In Mac OS, Java is installed at /Library/Java and your Java home folder should be /Library/Java/home.
  3. If you have multiple versions of JDK installed on same machine, then your Java home could be /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

For checking Java version please type java -version on terminal.

if you are installing Oracle Middleware / Weblogic you may face error : “Invalid Java home
To correct this error, follow these steps:-

1. cd /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
2. sudo mkdir jre
3. cd jre
4. sudo mkdir lib
5. cd lib
6. sudo ln -s ../../../Classes/classes.jar rt.jar

I hope this help. You can make a comment if you need any help from me.

How to use reCAPTCHA on your website? Example

What is CAPTCHA?

CAPTCHA is very important tool to prevent your website from SPAM. CAPTCHA script asks your user to enter some random words which can only identified by human eye.

Why Use CAPTCHA?

If you have any HTML form on your website, where people can submit information. You need to have CAPTCHA to stop auto submission from a bot. Some examples of forms are comment form or User Registration form. CAPTCHA script saves the HTML forms from auto submissions and save it from SPAM.

How to integrate reCAPTCHA?

reCAPTCHA is a CAPTCHA service offered by Google Inc. reCAPTCHA is best CAPTCHA service offered anywhere and it is free to use. Below is the guide to use reCAPTCHA at your website.

Check out the example of Recaptcha. You can download the source code from here.

Step 1: Sign up for Recaptcha

Go to Recaptcha and Sign up for reCAPTCHA service. You need to have Google account to use this service.

Step 2: Register your Website

You need to register your website for reCAPTCHA service. Go to https://www.google.com/recaptcha/admin/create and create keys for your domain. You will get public and private key for your domain.

Step 3: Client Side Integration

Recaptcha provides you several means to integrate it at your website. I am using AJAX API to use it.

Include recaptcha ajax javascript inside your head tag

[cc lang=”javascript”]

[/cc]

Then before your submit button use this code :
[cc lang=”javascript”]

[/cc]

We need to validate the user’s response. So include the validate function onSubmit call of your form.
Below is the validateCaptcha method which you can use to validate Captcha entered by user.
[cc lang=”javascript”]
function validateCaptcha()
{
challengeField = $(“input#recaptcha_challenge_field”).val();
responseField = $(“input#recaptcha_response_field”).val();

var html = $.ajax({
type: “POST”,
url: “verify.php”,
data: “recaptcha_challenge_field=”+Recaptcha.get_challenge()+”&recaptcha_response_field=”+ Recaptcha.get_response(),
async: false
}).responseText;

if(html == “success”)
{
$(“#captchaStatus”).html(” “);
// Uncomment the following line in your application
return true;
}
else
{
$(“#captchaStatus”).html(“Your captcha is incorrect. Please try again”);
Recaptcha.reload();
return false;
}
}
[/cc]

Step 4 : Server Side Integration

Download the PHP Recaptcha lib and store it on your server.

Here is the code to verify the user’s input. You can create a separate file on your server.
[cc lang=”php”]
is_valid) {
// What happens when the CAPTCHA was entered incorrectly
die (“The reCAPTCHA wasn’t entered correctly. Go back and try it again.” .
“(reCAPTCHA said: ” . $resp->error . “)”);
} else {
echo ‘success’;
}
?>
[/cc]

Thats it. Your Recaptcha is working. Try out a Demo of Recaptcha.

My 30 day challenge, inspired by Morgan Spurlock

Hello all, I have been out of blogging from quite a time and really believe that I have missed a lot of fun. Yesterday I went through an interesting TED talk which inspired me to take 30 day challenge. Here is the video where Matt Cutts (Google Web spam team head) describes the 30 day challenge.

So here I am following Morgan Spurlock’s philosophy.
My challenge is : To learn something useful everyday and blog it.

I will post my updates in this blog and I am quite determined that I will complete this challenge.

Day 1 : I started the day one with approving and replying comments on this website. Here is today’s entry for my challenge.

Why Apple iPhone 4S Remains Scarce in Market

When the iPhone 4S was launched towards the end of 2011, there were some who were skeptical about its ability to sell as well as its predecessors. This was due to the perception that Apple had only made minor improvements to the iPhone 4. However, shortages of the smart phone quickly ensued, proving this idea to be false and causing Apple to announce that some orders could well be delayed. The question is whether the iPhone 4S is still scarce in the current market or have manufacturers have finally got up to speed, allowing supply to meet demand?

Perhaps the biggest indication that the iPhone 4S is no longer in short supply comes in the form of Apple’s Q1 2012 sales reports published in January. They suggest that the first three months since new CEO Tim Cook took office have been the most successful ever for the firm.

Mr Cook was handed the position of CEO after Apple founder Steve Jobs died last year, stepping into a role that has seen him take charge of one of the world’s most valuable companies. Some had assumed that the untimely departure of Jobs might signal a downward spiral for Apple because of the importance of its visionary leader. However, Mr Cook has clearly had a positive impact and has been able to sustain the company’s growth during his early weeks in charge.

The iPhone 4S and the other available versions in this range sold just over 37 million units over the past three months, helping Apple to increase its revenues to more than $46 billion, with a profit of $13 billion. Shareholders enjoyed a dividend of $13.87 for each share, which is clearly due in part to the 128 per cent increase in iPhone sales that was fuelled by the popularity of the 4S and the increased affordability of 2010’s iPhone 4 and 2009’s 3GS.

There is little doubt that Apple has clearly worked through any problems on the production side of things so that the iPhone 4S handsets can be pumped out of the factory just as fast as they are being snapped up by consumers on the other side of the planet.

Of course, the iPhone 4S was created during a period of supply-chain problems for Apple, with the Japanese tsunami of March 2011 forcing it to push back the launch of the handset into the autumn. This upset its usual summer launch schedule and is likely to mean that the sixth iPhone, due in 2012, will also arrive later in the year to give the iPhone 4S a chance to corner the market once more.

Apple could experience shortages once the iPhone 4S replacement hits shelves because it will almost certainly be using a completely different design and set of internal components compared with its precursor. Experts are predicting that it will have a larger screen, perhaps as big as 4.3 inches across the diagonal, which will completely alter the shape of the device and prevent Apple from using the same parts as it did for the 4S.

Providing there are no major natural disasters, or indeed problems with paint that prevented the white iPhone 4 from emerging for month after month, the next iPhone should be launched on time. Meanwhile, the iPhone 4S is unlikely to sell out in the immediate future.

“Java Life” Rap Song From Oracle With Lyrics

Oracle has released a funny rap song on Java and life of Java professionals. A Java professional should not miss it.
Scroll Down for lyrics

SPOKEN:
In the cubicles representin’ for my JAVA homies…
In by nine, out when the deadlines are met, check it.

CHORUS:
We code hard in these cubicles
My style’s nerd-chic, I’m a programmin’ freak
We code hard in these cubicles
Only two hours to your deadline? Don’t sweat my technique.

Sippin’ morning coffee with that JAVA swirl.
Born to code; my first words were “Hello World”
Since 95, been JAVA codin’ stayin’ proud
Started on floppy disks, now we take it to the cloud.

On my desktop, JAVA’s what’s bobbin’ and weavin’
We got another winning app before I get to OddEven.
Blazin’ code like a forest fire, climbin’ a tree
Setting standards like I Triple E….

Boot it on up, I use the force like Luke,
Got so much love for my homeboy Duke.
GNU Public Licensed, it’s open source,
Stop by my desk when you need a crash course

Written once and my script runs anywhere,
Straight thuggin’, mean muggin’ in my Aeron chair.
All the best lines of code, you know I wrote ‘em
I’ll run you out of town on your dial-up modem.

CHORUS:
‘Cause…
We code hard in these cubicles
Me and my crew code hyphy hardcore
We code hard in these cubicles
It’s been more than 10 years since I’ve seen the 404.

Inheriting a project can make me go beeee-serk
Ain’t got four hours to transfer their Framework.
The cleaners killed the lights, Man, that ain’t nice,
Gonna knock this program out, just like Kimbo Slice

I program all night, just like a champ,
Look alive under this IKEA lamp.
I code HARDER in the midnight hour,
E7 on the vending machine fuels my power.

Ps3 to Smartphones, our code use never ends,
JAVA’s there when I beat you in “Words with Friends”.
My developing skills are so fresh please discuss,
You better step your game up on that C++.

We know better than to use Dot N-E-T,
Even Dan Brown can’t code as hard as me.
You know JAVA’s gettin’ bigger, that’s a promise not a threat,
Let me code it on your brain

WHISPERED:
so you’ll never forget.

CHORUS:
We code hard in these cubicles,
it’s the core component…of what we implement.
We code hard in these cubicles,
Straight to your JAVA Runtime Environment.

We code hard in these cubicles,
Keep the syntax light and the algorithm tight.
We code hard in these cubicles,
Gotta use JAVA if it’s gonna run right.

We code hard in these cubicles
JAVA keeps adapting, you know it’s built to last.
We code hard in these cubicles,
Robust and secure, so our swag’s on blast

CODE HARD
