If you are anything like me and spends a good amount of time on computer, your eyes may say you soon that "Hey! it's fantastic. Give me some comfort or else I'll take yours". You may soon face dry-eyes or sleeping dis-orders. Let's take some precautions to save them.
Now I'm not gonna discuss something like don't stare without blinking your eyes or maintain some distance from monitor, but here is a way to optimize your monitors brightness automatically according to the time-of-the-day and temperature.
Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night.
To install it in Ubuntu:

sudo add-apt-repository ppa:jonls/redshift-ppa
sudo apt-get update && sudo apt-get install redshift

To start the application, first find the coordinates of your location (lat:long). Then

redshift -l lat:long (eg: redshift -l 17.033:55.20)

For latest version and also Windows installation, visit the official website.

In my previous post, I mentioned a way to handle large integers by using BigInteger. Now I'm going to provide a very important usage of it. We often use for-loop. So here is the way to use it:

Ordinary integers:

for(int i = 1; i <= n; i++) {
 //Task to do
}

BigInteger:

for (BigInteger bi = BigInteger.valueOf(1);
                bi.compareTo(n) <= 0;
                bi = bi.add(BigInteger.ONE)) {
//Task to do
}

here n is a BigInteger variable.

Many of you might have wondered, as I did, how to deal with integers of say more than 50 digits or so. And might have thought about breaking the integer into parts or storing it in a string and parse letter-by-letter.
Java provides a class for such large numbers: BigInteger.
You can find it in the package: java.math.BigInteger
We can do some operations like addition, subtraction, multiplication, division etc, but slightly in a different way.
For detailed information on its usage, have a look at this.

Today I tried to a new project in eclipse and on clicking

File>New> 

I found

<No Applicable Items>

I'm not able to create any kind of project. Then I found a solution on ecipse discussion group.

There are some selections in the IDE in the upper right corner; Java, JAVA EE and Resource etc. It was set to Java EE. When I selected JAVA, I can now create new projects again

Today Apple released much awaited update cum upgrade OSX Mavericks as a free update.

• Swipe through Multi-Touch books with interactive features, diagrams, photos, videos, and more.
• Keep multiple books open while using other apps — great for writing a paper or doing research.

Maps
• Send directions from your Mac to your iPhone and use voice navigation when you’re on the go.
• Explore select cities in stunning, photo-realistic 3D with Flyover.
• See detailed directions, real-time traffic, and alternate routes.

iCloud Keychain
• Don’t worry about remembering passwords — iCloud Keychain fills them in so you don’t have to.
• Keep your website passwords, credit card numbers, and Wi-Fi passwords up to date across your trusted devices. Robust 256-bit AES encryption helps keep your information safe.
• Sign in once to all of your mail, contacts, calendar, and other internet accounts, and iCloud pushes them to all your Mac computers.

Multiple Displays
• Just plug in a second display to use it with your Mac — no configuration required.
• Access the Dock and the menu bars on each display.
• Use full-screen apps on any or all of your displays.
• Use your HDTV as a second display with Apple TV.

Notifications
• Reply to mail or messages right from a notification, without having to leave the app you’re using.
• Receive notifications for incoming FaceTime calls and reply with an iMessage or set a callback reminder.
• Receive notifications from websites, even when Safari isn’t running.

Finder Tabs
• Declutter your desktop by consolidating multiple Finder windows into one.
• Move files between your tabs by simply dragging and dropping them.
• Select a custom view — icon, list, or column — for each of your tabs.
• Use tabs with full-screen Finder to organize and access all your files and folders.

Tags
• Organize files with tags no matter where they’re located — in iCloud or on your Mac.
• Give a document as many tags as you want.
• Click a tag in the Finder sidebar to see all the files with that tag.

Advanced Technologies
• With energy-saving core technologies in OS X Mavericks, you can surf the web longer on a single charge.
• Watching iTunes HD video is now more efficient, so you can watch more video when you’re not plugged in.
• App Nap regulates applications you’re not using so they consume less energy.

iCloud Keychain on iPhone, iPad, and iPod touch requires iOS 7.0.3.

Multiple Display with Apple TV and an HDTV works with Apple TV (2nd generation or newer), iMac (mid 2011 or newer), Mac mini (mid 2011 or newer), MacBook Air (mid 2011 or newer), MacBook Pro (early 2011 or newer), and Mac Pro (late 2013).

Hello guys,
I planned to start this section a long back, but due to some of the reasons, which even I don't know, hadn't made it.
From now onwards, along with the regular workarounds, tips and tuts, I would like to blog some of the good web development tutorials, plugins etc and also good templates I came across.
So keep visiting...............

Today I'm searching for a way to mount a remote directory on my local machine, such that it acts like a local machine. The sole reason is to run the remotely compiled code locally.
I've found a nice article on it and would like to blog it here.
Here we go:

• Install SSHFS:

sudo apt-get install sshfs

• Add root to the fuse group: 

sudo adduser root fuse 

• Create the local backup director

mkdir backup

• Then mount the remote /home directory to backup:

sshfs -o idmap=user <username>@<remote system's ip>:/home backup

• Let's check if the remote directory got mounted to /backup:

mount

df -h

• To unmount the directory

fusermount -u backup

Check the backup folder to see your remote directory...
