Electrolysis in Firefox 48 Beta

Mozilla is finally rolling out the much-anticipated multi-process feature in its Firefox web browser. Named Electrolysis, this project is being called the biggest change ever made to Firefox. To give you the power-user ability and avoid crashing, Electrolysis will split the Firefox UI and content rendering processes.

Even with such a hugely exciting change, the develop isn’t taking any chances by throwing Electrolysis out there onto every Firefox user’s computer. Following an in-house beta testing period of Electrolysis, Firefox 48 is now in beta, meaning only a tiny percentage of users will even make the transition in order to give Mozilla the much-needed feedback it requires before rolling it out on a broader scale.




Electrolysis will separate UI and rendering processes

In the initial phase, Electrolysis will split the operations used to render web pages and browser’s GUI processes into two different parts. Firefox aims to avoid complete browser crashes with this trick as the browser UI will continue to work even if the rendering functions are crashed.

In the upcoming Firefox versions, Electrolysis will run each extension a separate process. This will help users spot the RAM-hogging extension.

Google Adwords Makeover

Google announced that its AdWords is getting a makeover, and has been rebuilt from the ground up, in order to fully accommodate the fact that for most of us, mobile devices are the way we access the World Wide Web.




Google has claimed that searches made from mobile devices are currently growing 50% faster than in any other area, so this new direction makes sense.

Significantly, the move will separate desktop and mobile devices in the way AdWords operates for each type of device.

Advertisers will be given the option to make mobile the primary focus of their campaigns, and also allow them to set different bids for desktop, tablet, and mobile devices.

The way the ads themselves look is changing as well.  Advertisers will now have an increase in headline characters and get one 80 character line description to sell their product instead of the two current 35 character lines.

Google had been considering redesigning the way their AdWords works for some time now, but only recently have felt that the wider world was now ready for the changes.

Logical AND operator [&&] vs Bitwise AND operator [&] in java

Program:

/**
 * @author Technoledgetree
 *
 */
public class Example {
private static int val=0;
private static boolean m2(int k){
val+=k;
return true;
}
public static void m1(int i){
boolean b;
b=i>=15 && m2(40);  // line 13
b=i>=15 & m2(15);    // line 14
}
public static void main(String a[]){
m1(0);
System.out.println(val);
}
}

Output: 15

Explanation:
  • at line 13, Logical AND operator is used, hence as soon as i>=15 becomes False it stops checking rest of the conditions.
  • at line 14, Bitwise AND operator is used, hence it will do the Bitwise AND operation with both the operands.
Note: 
  1. In case of Logical AND operation [&&] involving multiple condition, rest are not checked as soon as one of them becomes false, because result will always be false and Similarly, In case of logical OR operator[ || ], remaining conditions are not executed if one of them is true, because as soon as one operand becomes true, result of operation will be true, regardless of result of remaining condition.
  2. Because of skipping nature of Condition check; Logical operators are also called as ` Short Circuit ` operators.

Google Home - An Introduction

Google has jumped into the competition with its Google Assistant, which later this year will power a device called Google Home. It looks for all the world like a college dorm ambient light lamp, so much so that you run the risk of people picking it up to see what it is. Google’s VA aims to not only connect your home (ie, your Nest thermostat) and serve as a question-and-answer box, but also plans to leverage its powerhouse search engine with your own accumulated preferences to anticipate your every query. Or something like that.



Journalists who covered Google’s live demo press conference this week had a lot to say about it, most of it focusing on how Google is going to wipe Amazon’s Echo off the map with this new device.


Basically, Apple and Amazon needed the competition. Apple doesn’t offer a home connected model that lets you walk into a room and call out your every command. And Amazon doesn’t offer a phone, so users have to purchase an additional device that looks for all the world like a Thermos and carry it around with them when they’re away from their desktop Alexas. Google Home is building a VA scale that could potentially do it all, if it works, that is. That single drop of serious competition could spell great innovations across all models of virtual assistant.
