7 Uses for a Virtual Machine

7 Uses for a Virtual Machine

VMWare has announced the release of VMWare Server 1.0 for FREE. Formerly known as GSX server, this product allows you to take a reasonably powerful server (say a box with two processors and 4 GB of memory) and lets you serve up virtual machines. Virtual machines, by the way, are best thought of as little instances of a computer, acting as if it’s a whole computer with network IP and everything, running on a bigger box. So, you can load the software, build virtual machines, and those machines (software) will act like they’re full-fledged computers in their own right.

This isn’t dual-booting or partitioning. You can access these all at the same time. (The more running at one time, the slower things will eventually get). You can network them together with a virtual network switch.

Who cares? Too techy! Stick with me, kids.

Uses for Virtual Machines

Advertising

  • Try new operating systems– Want to try out Ubuntu? Put together a VM (shorthand for virtual machine) and build Ubuntu on it. Suddenly, you can launch and try dozens of operating systems without much hassle.
  • Test your software– Are you the next 37Signals? You can use VMs to try your software or web app or even site design on a variety of boxes by just building virtual machines and running the tests there. Because the “machines” boil down to a couple of files, the cool thing is, you can copy them, you can back them up. You can burn them to a DVD and ship a fully configured system to someone across the globe.
  • Set up an office quickly– Imagine you’re gearing up for a political campaign, or you’re going to build a retail store in a new town. You need an office with a mail server, a print server, a file server, and some desktop systems. You could have your people on the ground go buy a server from the local computer store (or ship one, whatever), and ship them the DVD with your images on it (or a hard drive). About a half hour later, you could have everything configured and running. Imagine emergency management logistics with this in place?
  • Small Biz disaster recovery– This isn’t highly recommended, but it’d work if you’re bootstrapping. Say you’re hosting a few webservers with your amazing app on them. Your house gets hit by lightning. Your site is off the air. Now, imagine that scenario but you’ve got virtual backups of the latest build and configuration ready to install and deploy wherever else you’ve got a point of presence. Poof. You’re online again.
  • Build kid boxes– Build Edubuntu (a kid flavored Ubuntu) on a virtual machine for the kids (the specs I mention above are for heavy users, but you could get away with a lot less if you only ran ONE VM). If (when) things go sour from one too many “tweaks,” just drop the VM and restore from your pristine copy. Talk about easy. You can get them back on the net in under 10 minutes.
  • Backup your system– When you get ready to move from XP to Vista, you can use VMWare to make a backup of your old system. If things go horribly sour, you could have the VM version up and running in short order. By the way, you can have TWO servers, and have a copy of the VM on both. This would give you even more business continuity, should something happen to the server.
  • Save Legacy Systems– Offices and data centers often have an old box around that just can’t be mucked with. There’s additional software you can use to do what’s called a P2V switch, a physical-to-virtual conversion, where the old box’s “image” gets copied onto the virtual machine files, and thus, gives you a hopefully-operational clone of the old grandpa box in the corner.

This is on the techier end of life hacking, I admit, but you might be able to glean some ideas from this that translate to what you’re doing in your own world. And believe me, virtual machines do make your life easier, if you have to work with lots of moving parts. I use the big daddy version of this software in our enterprise systems, and it’s a lifesaver.

And not for nothing, the people who WORK for VMWare (owned by EMC), and who represent them in sales and in customer service, are really nice and helpful. The community around the product is really good. The documentation and forum support is good. This is a robust software you can really put to some good uses.

How to Become an Early Riser and Stay Energetic

How to Become an Early Riser and Stay Energetic

When you become an early riser, you’ll experience a lot of benefits including feeling more energized and having more time to do what you want.

If you’d like to become an early riser, there are some things you should know before you run off to set your oft-ignored alarm clock.

So how to become an early riser?

Here are five tips I’ve discovered to be most helpful in making the transition from erratic sleeper to early morning wizard:

1. Choose to Get up Before You Go to Sleep

You’re not very good at making decisions when you’ve just woken up. You were in the middle of a dream in which [insert celebrity crush of choice here] is serving you breakfast in bed only to be rudely awakened by the harsh tones of your alarm clock. You’re frustrated, angry, confused, and surprised. This is not the time to be making decisions about whether or not you should stay in bed! And yet, most of us leave the first decision of our day to be made in a blur of partial wakefulness.

No more!

If you want to be a consistently early riser, try making your decision to rise at a specific time before you go to sleep the night before. This frees you from making the decision in the morning when you’ve just woken up. Instead of making a decision, you have only to follow through on your decision from the night before.

Easier said than done? Of course. But only for the first few times. Eventually, your need for raw willpower to get out of bed will diminish and you’ll be the proud parent of a new habit!

Steve Pavlina suggests you practice getting out of bed during the day[1] to get a few of the “practice sessions” out of the way without the early morning fog in your head.

2. Have a Plan for Your Extra Time

Let’s say you’ve actually made it out of bed 2 hours before you normally would. Now what? What are you going to do with all this time you’ve discovered in your day?

If you don’t have something planned to do with your extra time, you risk falling for the temptation of a “morning nap” that wipes out all the work you put into getting up.

What to do? Before you go to bed, make a quick note of what you’d like to get done during your extra hours the following day. Do you have a book to write, paper to read, or garage to clean? Make a plan for your early hours and you’ll do more than protect yourself from backsliding into bed.

You’ll get things done and those results will fuel your desire to build rising early into a habit!

3. Make Rising Early a Social Activity

Your internet or social media buddies just don’t have enough pull to make your new habit stick in the long term. The same cannot be said for the people you spend time with as part of your early morning routine.

Sure, you could choose to read blogs for two hours every morning. But wouldn’t it be great to join an early breakfast club, running group, or play chess in the park at 5am?

The more people you get involved in making your new habit a daily part of your life, the easier it’ll be to succeed.

4. Don’t Use an Alarm That Makes You Angry

If we’re all wired differently, why do we all insist on torturing ourselves with the same sort of alarm each morning?

I spent years trying to wake up before my alarm went off so I wouldn’t have to hear it. I got pretty good, too. Then I started using a cellphone as my alarm clock and quickly realized that different ring tones irritated me less but worked just as well to wake me up. I now use the ring tone alarm as a back up for my bedside lamp plugged in to a timer.

When the bright light doesn’t work, the cellphone picks up the slack and I wake up on time. The lesson learned? Experiment a bit and see what works best for you. Light, sound, smells, temperature, or even some contraption that dumps water on you might be more pleasant than your old alarm clock. Give something new a try!

5. Get Your Blood Flowing Right After Waking

If you don’t have a neighbor, you can pick fights with at 5am, you’ll have to settle with a more mundane exercise. It doesn’t take much to get your blood flowing and chase the sleep from your head.

Just pick something you don’t mind doing and go through the motions until your heart rate is up. Jumping rope, push-ups, crunches, or a few minutes of yoga are typically enough to do the trick. (Just don’t do anything your doctor hasn’t approved.)

If you live in a beautiful part of the world like me, you might want to use a bit of your early morning to go for a walk and enjoy the beauty of the world around you.

If you have a coffee shop open within walking distance, dragging yourself out of bed for a cup of coffee to savor on your walk home as the world wakes around you is a wonderful experience. Try it!
