Security Flaw In Amazon’s Kindle Touch

The H’s associates at heise Security demonstrate a proof-of-concept exploit for the Kindle Touch which causes the kindle to reboot. There is a security flaw in web browser built into Amazon’s Kindle Touch eBook reader. Whenever any user navigates any specially crafted webpage the kindle executes arbitary shell commands as root that allows attackers to access the eBook reader’s underlying Linux system and potentially steal the access credentials for the Amazon account linked to the Kindle, or purchase books with account of Kindle’s user. Check this report and this video.

Bitcoin Vending Machine – Exchange Euro Coins For Bitcoin (Wallets)

Bitcoin Vending Machine is a mechanical vending machine which exchanges 1€-coins for Bitcoin. This machine works with the service of easywallet.org which provides a Bitcoin wallet with web interface similar to online banking. One can only access the account through a secret link which you get in exchange of 1€-coin. Using this link a customer can send 1€ to another Bitcoin user.

Here is an announcement on bitcointalk

How Everybody Reacted On Breaking Bad Season 5, Live Free Or Die

“Live free or die” is the name of Breaking Bad’s fifth season premiere. Series is one of the most serialized in American television history created and produced by Vince Gilligan. It is the story of Walter White (Bryan Cranston) who is a struggling high school chemistry teacher is diagnosed with lung cancer at the beginning of the series. He turns to life of crime, producing and selling methamphetamine with a former student, Jesse Pinkman (Aaron Paul), to secure his family’s financial future before he dies.

Look how people are reacting and what they are guessing for Breaking Bad, Season 5:

Mike was the one who used the balloon to mess up the electrical wires, not Walt. Great start to the season. Starting the season with a scene over a year into the future was great (again). It makes me want to know what happens so much more.

KendoVT

Walt is a bad man, but i cannot stand mike. he criticized walt and called him the “answer man” but mike always seems like he thinks he is above everyone else, and he has all the answers. mike is just such a smug jerk. walt is too, but i like walt. i feel bad for skyler though. she gets so much crap. but mike, man i officially find him more irritating than tyrus.

David Gueirlla

Mike’s great! “I can imagine a lot of outcomes, but none of them end with Miller time.”

Somebody

Jesse doesn’t have a piercing down there…otherwise a lot more than that lap top would have been ripped away from him.

Ejnewcomer

Skyler will start attempting to kill Walt

Ricl

I think as walt has become the antagonist, Jesse role has switched he now is turning into the protagonist, which might end in walts ultimate demise.

Tisha

I think the laptop will be repairable I wont be surprised if later in the series we hear from Hank about it being repaired, I really can not stand Skyler her up and down moods and blank facial expressions are annoying she had her chance to run away but the money attracted her. Knowing the clip we seen from the end of the series it will no doubt be some unrelated reason why he is there maybe picking up a gun for one of his new henchmen just like how we waited all season to see his house burn to realize it was a plane crash.

Frosty

I think the bank account info will possibly lead the DEA to Saul who is now more susceptible to turn in Walt over fear over his own life given Walt’s intimidating gestures in the meeting the had during s5e1.

Cloud Based Scripting Language For Light-weight Application Development In Google Apps Platform

Google Apps Script is cloud based scripting language for light-weight application development in Google Apps platform. It is based on JavaScript, gets executed in the Google Cloud and provides easy ways to automate tasks across Google products including third party services.
Google App Script is based on JavaScript like syntax. It uses Google Web Toolkit (GWT) for creating and displaying elements of user interface. GWT is easy to learn, and completely abstracts the complexity of AJAX/HTML from the developer. It is a Cloud based debugger for debugging App Scripts in the browser. It can be used for creating tools to perform simple system administration tasks etc.

Limitations: Currently it doesn’t allow connection to internal (behind-the-firewall) corporate databases, which is key to building business apps. Lacks other connectivity like LDAP connectivity and limits the level to which GAS can be used in the enterprise.

Linus Torvalds Bought Nexus 7 So Why Not You ?

If you are confused between Nexus 7 & New Samsung Galaxy Note Sporting 5.5 Inch Screen or any other smartphone and unable to take decision then you must know:

  • Linus Torvalds pre-ordered Nexus 7.
  • Linus Torvalds is checking delivery date of Nexus 7 again and again.

Now you would be saying that you don’t take your decisions by watching what others are doing. What do you think? You are wiser than Linus Torvalds? You think Linus Torvalds comes in ‘others’ category.

It is good if you don’t watch others and make your decisions but truly this is what you really do but you don’t know. You see adds, you watch movies and you buy stuff.

Many of you purchased Sony Xperia after watching Spiderman but are you really satisfied with Sony Xperia? If you say yes then you are very lucky because others who purchased it realized that the most important feature (seeing what they purchased Sony Xperia) actually don’t works. Hence it is much-much better to watch Linus Torvalds and buy Nexus 7 instead of watching Spiderman and buying Sony Xperia.

Everybody experiences some hardware-software conflict in such smartphones because developers are different. If you are willing to experience this conflict everyday then don’t buy Nexus 7.

Now 300 Million People From The Middle East & North African Countries Can Acquire Direct Access To BitCoin

About 300 Million people living in the Middle East and North African countries were not having direct access to bitcoin but today Bitcoin Nordic introduces cashU payment option. CashU prepaid cards can be bought at locations all over the Middle East and North Africa.

CashU prepaid card is way to top up a cashU account. CashU is trying to make itself globally available by cooperating with Ukash and some other payment mechanisms.

Lasse Birk Olesen, Head of Operations at Bitcoin Nordic says:

“We are very excited about introducing cashU as a payment option on Bitcoin Nordic. This will expose Bitcoin to a whole new region”

CashU prepaid cards are now available in the Middle East and North African countries with large presence in the countries like: Algeria, Egypt, Iraq, Bahrain, Kuwait, Saudi Arabia, Palestine, Qatar and United Arab Emirates

Purchasing bitcoins with CashU  is MtGox 24h average + 15% at the moment but Bitcoin Nordic is looking forward to lower down this as soon as volume increases.

Bitcoins for CashU is now available at www.bitcoinnordic.com

Firefox 16 Now Supports HTML5 getUserMedia

Firefox 16 now supports HTML5 getUserMedia. It enables access to webcam without any plugins.

There is an entry in about:config, set that to true. In case you need to add a new entry then:

  • open about:config
  • Right click any entry.
  • Select ‘New‘ >> ‘Boolean

Add the following entry and set it true:

media.navigator.enabled

Remember to define callback methods right within the getUserMedia() method as shown below:

navigator.getUserMedia(gumOptions,
function successCallback(stream) {
// Replace source of video element with stream from camera
if(navigator.getUserMedia==navigator.mozGetUserMedia) {
video.src = stream;
} else {
video.src = window.URL.createObjectURL(stream) || stream;
}

video.play();
},
function errorCallback(error) {
console.error(‘An error occurred: [CODE ‘ + error.code + ‘]’);
video.play();
});

It won’t works in-case you defined it elsewhere. No need to use CreateObjectURL to pass the stream the video element. Pass the stream directly. video.src=stream

Paul Rouget of Mozilla, created a video tutorial demonstrating HTML5 getUserMedia:

Another ILL-Defined Copyright Law, This Time From Japan

Japanese would be experiencing a new rubbish  from the coming October. Japanese police is monitoring the file sharing networks so that they can raid the innocent people who are downloading videos instead of watching them online. Yes, in accordance to this law you can stream videos online but you are not free to save those digital copies locally. Other than this you can save comic strips from other websites and cut, copy and paste all text because schooled idiots from Agency for Cultural Affairs has interpreted ‘DOWNLOAD’ as audio-video recording.

Actually downoad is the process of copying data but Japanese Agency for Cultural Affairs thinks that download is just audiovisual recording.

They say that TV shows which are already been broadcast and yet not available in the market may be downloaded.

A Japanese Lawyer writes:

Many people remain unclear about what is exactly banned under the law.

For checking that the content is safe for download this agency asks Internet users to look for a recording industry trademark called the L Mark which cannot be used by just anyone because if you need to use this mark then you have to join Recording Industry Association of Japan and pay money to them. They don’t say a word for Creative Common and GPL. However if you got the audiovisual content legally then you are free to share it with your friends by mailing them because mailing and download are two different words where download looks a bit pirate type.

Listing MySQL Databases

For showing all database:

SHOW DATABASES;

In case you need to filter database by name:

SHOW DATABASES LIKE ‘pattern’;

For complex filtering of database use WHERE Clause:

SHOW DATABASES WHERE conditions;

With WHERE clause one can use regular expressions like ‘<‘ and ‘>’ operators, string functions etc. for filtering records returned by SHOW DATABASES.

PHP Arrays

Arrays are sets of data; can be defined in a PHP Script. Arrays can contain other arrays inside them without any restriction, hence building multidimensional arrays. Arrays can be referred to as tables or hashes.

You can create Arrays in two different ways. The first involves using the function array. The second involves using square brackets.

First is The Array Function Method

In the array function method you create a array in the scheme of:

$foo = bar()

For example, to set the array up to make the keys sequential numbers (Example: “0, 1, 2, 3”), use:

$foobar = array($foo, $bar);

This would produce the array as follows:

$foobar[0] = $foo
$foobar[1] = $bar

It is also possible to define the key value:

$foobar = array(‘foo’ => $foo, ‘bar’ => $bar);

This would set the array as follows:

$foobar[‘foo’] = $foo
$foobar[‘bar’] = $bar

And,

Second is The Square Brackets Method

The square brackets method allows you to set up by directly setting the values.

For example:

To make $foobar[1] = $foo, what you should do is:

$foobar[1] = $foo;

The same applies for setting up the key value:

$foobar[‘foo’] = $foo;
