#1: Admit you are at risk of an addiction.
More and more people in the world are becoming addicted to the internet. You are not the only one with this problem, it is becoming more and more common and more and more well known. Do not be embarrassed; find others with the same problem and help each other beat it.
#2: Set aside limited time for computer use.
Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you can see every day. Try keeping the lid closed when you are less likely to use it. If you have a desktop PC, try not to go near it or put something over it like a sheet.
#3: Call people instead of sending text messages.
Call a friend and ask them to go outside for at least 3 hours a day. This will distract you from the computer. If you're in school, try doing your homework together over the phone or in person.
#4: Use an alarm clock or timer.
Before using your computer decide on a time such as 30 minutes. Set the clock or timer and make sure that you get off the computer when the time is up. Alternatively create a shutdown timer shortcut on your desktop (google search "shutdown timer" for tutorials). This can be programmed to shutdown your computer after a predesignated time after it has been activated.
#5: Make copies of the information you need.
If there are pages which you look at constantly for information, simply copy all the text and save it in a file, or even print it off. This will stop you from using the Internet so often, and it will stop you from drifting to another page.
#6: Try using the computer at the library.
You won't be as tempted to look at certain website sand they do have a limit on how long you can stay online. Also, the library is a good place to get some good books and magazines to read, so you won't be as tempted to be on the Internet at home.
#7: Get a hobby or an interest that doesn't involve the internet, video games, computer, TV, cell phones, smartphones, iPads, or portable media players.
Get involved with teams, clubs, sports, church, music, dancing, singing, etc. Go for a run with a friend or get exercise some other way. Go to bed on time and get a good night's rest. Keep up with the local events in your community. There may be talks, film screenings, concerts, local sporting events, and book signings etc. Find some, as long as it is not on the internet, and get involved.
#8: Put your obligations first.
If you are a student then do your homework and study. If you're in the working world, prioritize what you actually need to get done, rather than procrastinating with internet activities. Make a to-do list for each day and stick to it, only allowing yourself fun-focused internet time or distractions after you're through with your other obligations
#9: Help with meals.
Anything that gets you off the computer for a while will help and increase your confidence that you can stay off even longer. Cook or bake something one night for the family. Don't eat meals at your computer! Eating at a separate place will help you to not go online.
#10: Hang out with friends.
Plan a trip to the bowling alley, mall, or ice rink. Get a friend to walk a dog with you for the afternoon. Avoid places that have free internet access such as coffee shops.
There are many other ways on how you can avoid living your life in front of computer. Get up and do exciting activities. If you know other ways to beat computer addiction, share it with in the comment section below. If you have questions, feel free to ask in the comment section.

From Bo Sanchez's How to Turn Thoughts into Things
You know how old I am?Here’s a hint: My first computer monitor wasn’t black and white.
It was green.
And the only real popular computer game in my time?
Pacman. It was a green round character with a big mouth that ate everything in sight. Just like the greedy politicians of the Philippines.
If your dictionary was published before 1980, throw it away. Thanks to the computer, the English vocabulary has radically changed.
When I was young, a mouse was a furry animal.
A mouse pad was the house of a furry animal.
A virus caused the flu.
A bug was an insect.
A hard drive was a difficult journey.
An apple was a fruit.
And windows were rectangular holes on the wall.
My friend (whose name I won’t divulge because it’llbe hazardous to my health) has been frozen in time when itcomes to computers. She refuses to learn. One day, her bossenters her office and says, “I need new Windows for theoffice.” He was referring to the computer’s operating systembut she didn’t have the foggiest idea what he was talking about. Being the bubbly girl that she was, she said, “Cool! Interior design is my specialty.”
What is an operating system? It’s the system that operates the computer. (Man, I’m bright.) OK, let me try that one more time. The operating system is the most basic program of your computer. Your various applications — Word, Excel and Powerpoint — sit atop the operating system or OS.
Why am I giving you a lecture on computers?
To make a very important announcement.
Friend, I’ve just discovered the operating system of the universe.
To Be Successful, Follow the Operating System
I believe in blessing.
Luck is based on chance.
Blessing is 100 percent sure!
What people define as luck, I define as getting ready to be blessed.
My belief is simple: When the soul is ready, the blessing will appear.
Are you ready for the truth? Right now, you’re swimming in an ocean of blessings. You don’t see this ocean but it’s there all around you.
If you lack blessings, it simply means you lack readiness to receive the blessings. There’s no shortage of blessings. There’s only a shortage of your readiness.
The key? Get ready.
How? By planting seeds.
Let me now tell you about the Operating System of the Universe.
Friends, the Operating System of the Universe is the Law of the Harvest.
This is what governs the world.
And this is what governs your life.
The Law of the Harvest states:
What you plant, you harvest. What you don’t plant, you don’t harvest. The more you plant, the more you harvest. The less you plant, the less you harvest.
If you plant mangoes, you get mangoes.
If you plant bananas, you get bananas.
And if you plant love, you harvest love.
If you plant hatred, you harvest hatred, too.
Share with me your thoughts after reading the excerpt of How to Turn Thoughts into Things in the comment section.

Ubuntu is a free/libre, open-source computer operating system with 20 million users worldwide. But it’s also so much more than that: it is an ethos, a collaborative project and, first and foremost, Ubuntu is a community of people.
The Ubuntu Philosophy
Ubuntu is an ancient African word meaning ‘humanity to others’. It also means ‘I am what I am because of who we all are’.
It is this South African philosophy that sets Ubuntu apart from other operating systems because it brings the spirit of humanity and community to the world of computers. Ubuntu users share a deeply held belief that software should be freely accessible to everyone regardless of language, disability, or income.
Proprietary Software vs Free/Libre Open-Source Software
Proprietary software is designed, developed and marketed by a company as their own system. It is sold for profit and functions on only one type of computer. Examples of proprietary operating systems include Microsoft Windows and Mac OS X. The source code of these systems is not freely available and if you tried to modify or distribute it would constitute a felony.
Ubuntu, on the other hand, is NOT proprietary software because it is actively maintained by the FLOSS community.
FLOSS is not the thin, waxy filament that you run through teeth. FLOSS is the acronym for Free/Libre Open-Source Software. FLOSS software is different from proprietary or commercial software because it is:
• FREE to use
• FREE to share, and
• FREE to develop
This means you can download and use Ubuntu without paying money. You can then make copies of the software and distribute it to as many people as you want. Finally, the source code of Ubuntu’s operating system is freely available, so you can inspect the program and make changes to suit your own needs.
How Can Ubuntu Be Free?
1. It’s Maintained By The FLOSS Community.
Ubuntu is both a global community and collaborative software project. People around the world freely share their time and skills to:
• test software bugs
• write user documentation
• design artwork
• provide user feedback, or simply
• spread the good word of Ubuntu.
2. It’s Managed & Funded By Canonical
Although Ubuntu is maintained by the FLOSS community, it is managed and funded by a privately held company called Canonical Ltd. Canonical was founded (and funded) in 2004 by South African entrepreneur, Mark Shuttleworth, the visionary behind Ubuntu.
Why Use Ubuntu?
There are many reasons to use Ubuntu, but here are some of the most important ones:
• It’s free and open source: shared code, shared efforts, shared principles, no cost.
• It’s easy to use, trial and install: you don’t have to be an expert.
• It’s beautiful, sleek, and stylish.
• It’s stable and fast: usually loads in less than a minute on modern computers.
• It has no major viruses! Ubuntu is immune to computer-crashing Windows viruses. Say goodbye to Blue Screens of Death!
• It’s up-to-date: Canonical releases new versions of Ubuntu every six months and also brings you regular updates for free.
• It is supported: you can get all the support and advice you need from the global FLOSS community and Canonical.
Installing Ubuntu
This option will replace your current operating system with Ubuntu. A complete installation will run the fastest and smoothest on your computer, but requires a full commitment to leave behind your old operating system.
Visit http://www.ubuntu.com/download/ubuntu/download for a step-by-step instructions on how to do this.
Support & Community
Looking for help but are not sure where to go? The Ubuntu community is here to support you in multiple ways to suit your individual needs. You can:
• seek support in-person by contacting your Ubuntu Local Community,
• access free documentation online, or
• use Launchpad to answer your most technical questions.
Whether your preference is in-person or online, there is a passionate Ubuntu community willing to share their expertise and knowledge with you.
If you have questions about using or installing Ubuntu, feel free to ask in the comment section.

Although Windows 7 is more secure than its predecessors, it remains vulnerable to security threats. Listed here are the five steps for securing Windows 7 desktops.Thankfully, there are several steps you can take in securing Windows 7 desktops to help mitigate some of these threats. In this tip, you will learn five steps for hardening Windows 7 desktops.
Local security policies
The first step is to create a local security policy for your Windows 7 desktops. Remember that even if a desktop is a domain member, Group Policy settings residing in Active Directory do not apply until a user logs in to the domain. Local security policy settings are the primary defense mechanism against a user who logs on to the machine locally. When a user does log in to a domain, the local security policy settings are merged with Active Directory-level policy settings to form the effective policy. As such, a local security policy can also help to protect against any accidental omissions in your group policy objects.
A local security policy contains most of the same settings as the Active Directory-based Group Policy settings. You can access the local security policy by opening the Control Panel and clicking on System and Security/Administrative Tools/Local Security Policy. See the Local Security Policy interface shown in Figure A.

| Figure A |
User Account Control
When Microsoft created Windows Vista, it included a new security mechanism called User Account Control (UAC). UAC intercepted changes that were made to the system, and asked the user for approval. That way, if a change was being made as the result of a malware infection, the user would have a way of preventing the action.
Unfortunately, User Account Control went down in history as the single most annoying Windows feature of all time, as many security pros know, because Vista users could hardly do anything that affected the operating system's configuration without coming face to face with a UAC prompt. That being the case, Microsoft made some changes to User Account Control in Windows 7.
In Windows 7, Microsoft provides a slide bar, which is shown in Figure B below. This slide bar allows administrators to tune how aggressively User Account Control behaves, and specifically the volume of confirmation prompts users receive. Although some may find it annoying, I recommend making User Account Control behave more aggressively. I have recently encountered a couple of situations in which serious malware infections could have been prevented had User Account Control provided notification of the impending infection.

User rights
When malware attempts to infect a PC, that malware has the same rights as the account that it is running under. Although malware may occasionally exploit a service account, it is far more common for it to run under the same context as the user who is logged in. Because of this, Microsoft recommends users be given the lowest level of access to the system possible. That way, if a malware file is executed, it may not have sufficient rights to cause any damage.
The level of access granted to local user accounts can be controlled by opening the Control Panel and clicking on User Accounts/User Accounts/Manage User Accounts. You can control the user account permissions through the resulting dialog box, which is shown in Figure C below.

| Figure C |
Malware protection
Even though Windows 7 is far more resistant to malware infections than Windows XP, malware infections can and sometimes do occur. While there is no substitute for third-party antivirus software, Microsoft provides a couple of different antimalware features that you can use to provide a basic level of antimalware protection.
One such feature is Microsoft Security Essentials, which is a free antimalware application designed for home and small business users with 10 or fewer users. You can download Microsoft Security Essentials at the Microsoft website.
Microsoft provides another antimalware feature called Windows Defender. This is an option for enterprises with more than 10 users. Unlike Microsoft Security Essentials, Windows Defender is built into the operating system. However, organizations must "turn on" Windows Defender because it is not enabled by default. See Windows Defender in Figure D.
 |
| Figure D |
AppLocker
In Windows XP, Microsoft introduced a feature called Software Restriction Policies. Software Restriction Policies were a collection of Group Policy settings designed to prevent users from running unauthorized software on their desktops.
Ultimately, Software Restriction Policies proved to be minimally effective. The policy settings were complicated and easy to circumvent. In Windows 7, Microsoft created a next-generation version of Software Restriction Policies, which is called AppLocker.
AppLocker lacks a centralized management console, so it isn't effective in large organizations or in organizations with highly dynamic desktops. However, AppLocker can help smaller organizations prevent malware infections by preventing unauthorized software from running on user's desktops. AppLocker is shown in Figure E.

There will be times when additional steps will be needed in securing Windows 7 desktops, but these five security techniques can go a long way toward effectively securing Windows 7 endpoint deployments.
