Other Tips and Tricks:

1. To Speed up Mozilla Firefox:

Type about:config in the address bar and hit Enter button, it will show you message “This might void your warranty!” Click on the button: I’ll be careful, I promise! then in the filter field type network.http , and change the following settings (Double-click on them to change them)

change network.http.pipelining and network.http.proxy.pipelining to true

Set network.http.pipelining.maxrequests to a number like 8.

Now, right-click and select New -> Integer.

Name itnglayout.initialpaint.delay and set its value to zero.

This is the time the browser waits before it acts on information it receives.

2. Handling Multiple Tabs with Keyboard:

Mozilla Firefox provides feature that you can handle multiple tabs by keyboard. Here are some tips to use multiple tabs by using keyboard.

Ctrl+Tab ->Rotate forward among tabs)

Ctrl+Shft+Tab -> Rotate to the previous tab)

Ctrl+1-9->Jump to a specific tab

3. Changing the behaviour of close button:

Sometimes by mistake you click on close button . Here is a trick to remove or close tab button.In the address bar Type about:config and press Enter button, then in filter field search for browser.tabs.closeButton. When you find it double-click on the given result. This inturn will show you a prompt with default value 1. Change the value to different values for different behaviours.

Enter 0 ->displays close button on the active tab only.
Enter 1 -> displays close button to all tabs.
Enter 2 ->avoids displaying any close buttons.
Enter 3 ->displays single close button at the end of the tab bar.

4. Opening multiple websites when you start Firefox:

In menu bar, click on ‘Tools’ option. Then click on ‘Options’ button .
Open multiple websites in Firefox

Under main tab, Look for ’startup’. Then type the website address/URL in ‘Homepage’ box separated by | symbol.

For example, if you want to open Google and Yahoo at the same time, then type – www.google.com | www.yahoo.com in Homepage box. Then Restart Firefox and you will see Firefox loading all 3 websites.

A Thermometer To Stick On The Skin

A small patch measures the temperature of a person with high accuracy and continuously. It is a soft square of 2 cm side that sticks to the skin. Consists of flexible sensors and electronic circuits, it measures the temperature of the carrier with an accuracy of 0.02 ° C. It was created by an international team of researchers, who presented in the journal Nature Materials.

Applied to an area of several square centimeters, it can measure different temperatures in different areas of the skin simultaneously, and observe how the heat is distributed in this area. Another advantage of this tool to fundamental aim: the measurements are continued until the person is wearing the patch, which can be observed temperature changes over time.

The system is dependent on an external power source. Researchers are studying ways to do without it, for example using photovoltaic microcells included in the patch.

A Super Capacitor Capable Of Supplying Energy On One Time Charge

Scientists at the university Vanderbilt in Nashville, Tenn., have developed a super capacitor made of silicon. Once heretical idea, today the idea to take the form of silicon chip capacitor is not so crazy.

This capacitor would provide energy for a range of several weeks on a single charge, or build solar cells able to load with or without sun. Published in the journal Scientific Reports, the first super capacitor stores its silicon charge accumulating on the surface of a porous material.

A difference from the traditional batteries that operate in chemical reactions, the super capacitor can be charged in a few minutes while her discharge may last much longer. Silicon had been regarded as unsuitable for super capacitors because of its property but can react with the electrolytes that allow the storage of ions.

 “If you ask experts to make a super capacitor with silicon, you will get the answer that it is a crazy idea," says assistant professor Cary Pint, who leads the development team of Vanderbilt University. "But we can say is easy to do." Team Pint covered the silicon atoms, a very thin layer of a few nanometers of graphene, which stabilizes the silicon surface, perfect for storing the necessary load.

"Everything that defines us in modern world needs electricity," says Pint. “The more we can integrate the storage of electricity in existing materials and devices; they are more compact and efficient.”

Utilizing Miniature Surveillance Cameras

Surveillance cameras have come a long way in recent years.  They are now within financial reach of most homeowners.  With the advent of the internet, IP cameras, or internet protocol cameras, enable homeowners and business owners alike to have a surveillance system that is high tech, full of options, and reasonably priced.  The simplest system would be comprised of one mini video camera and an internet connection.  Of course, multiple cameras can be added when the owner desires.  Because the majority of homeowners and businesses usually have an internet connection, they only need to install a set of cameras to create a modern security system.  This can have applications for such as watching the entrance to a condo, observing customers by a cash register in a small business, or more discrete uses in either a business or a home.

Business Use of Small Surveillance Cameras

Profit is always the prime directive for a business.  Besides competing with other businesses, a number of factors can detract from a company’s bottom line.  Some of them are reasons a small business may want to install a digital surveillance system. These include worker’s compensation insurance abuse.   With enough cameras in place, a manager can verify what an employee was doing when he or she alleges that they were hurt on the job.  If there was an obvious injury, the process will go quickly, and the company can see exactly how it happened and try to alter safety procedures as appropriate.  If there was no injury, no money needs to be paid.  In the long run, both ways can save money for a company.   Another way to use IP cameras is to observe employee behavior.  A mini-video camera no bigger than a web cam can be placed unobtrusively in various locations in a facility.  These might include a building entrance, a staff lounge, above an assembly line, and so on.  Perpetual tardiness, employee efficiency, or financial impropriety may be observed this way, and personnel decisions can be made as necessary.  

Home Use of Discreet Surveillance

Homeowners, especially parents, may have many reasons to want a good security systems based on the use of IP cameras.  Parents can worry about their children in many different situations, and discretely placed cameras can help parents know what is going on even when they can’t be right there.  Cameras now come in many forms that don’t look like cameras, such as a faux smoke alarm, an AC adapter, or even a coat hook.  Children and visitors won’t know there is a camera, so they will act naturally.  If a teenager makes a bad choice with the liquor cabinet, or if teenage girl is home alone with a new boyfriend, the cameras can observe what transpires.  Across town, parents can check in via the wonders of the internet.  If the parents are out on the town, and they aren’t sure about the new babysitter, a hidden camera can tell them what is going on back at the house.  This can bring peace of mind to a worried parent.  Security from theft is another issue for homeowners.  Motion sensor cameras can be trained on entrances.  There is no need to sift through hours of blank screen.  When someone approaches the door, the camera comes on, and you can see it in high resolution images.  If a crime is committed, or even in there is suspicious activity, evidence will be apparent.

Google Chrome adds a function for automatic malware blocking

Google enhances the security of the browser by adding a feature that detects and blocks the download of malicious software. Google is soon going to introduce a new security feature in its Chrome browser. This is an automatic download of malware blocking.

Users will be notified by an alert message to be displayed at the bottom of the browser window. This feature is currently being tested in the developer version of "Canary” of Chrome. It will address the malware disguised as legitimate downloads that can modify browser settings or install adware.

"The wicked push you to install and run this kind of software by hiding in something you might want, such as a free screen saver, a video plug-in or, ironically, an update safety," explains Google. And in the Chrome version 29, it offers an option to restore the default settings in case of infection by malware.
