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.

20 Unusual Uses for Coca-Cola That You’ve Never Considered

20 Unusual Uses for Coca-Cola That You’ve Never Considered

Coca-Cola is an adored product the world over. While keeping yourself in good health means moderating how often you enjoy this drink, Coca-Cola lovers will be happy to hear that there are plenty of uses for the soda pop that don’t involve ingesting it. Impressively, Coca-Cola can be used to help you clean, get rid of rust, and even help maintain your garden. Whether you are looking for a way to finally get rid of those pesky stains, or just want to find new ways to love this drink, these 20 jaw-dropping and unusual uses for Coca-Cola will blow you away.

Kill pests in your garden

Coca-Cola is also an effective pest control method for your garden. To rid yourself of plant munching slugs and snails, pour a small bowl of Coca-Cola and place it near your garden or flowerbeds. The smell will attract these crawling bugs and the drink’s acidity will kill them.

Defrost your windshield

Incredibly, Coca-Cola can also defrost your windscreen in the wintertime. Simply pour Coke liberally across your windshield and wait about a minute. The ice should turn to slush for easy removal.

Clean your pans

Coca-Cola is also useful in the kitchen, especially on burnt pans. For any pan with burnt on messes, pour a can of Coke into the pan and simmer. The mess should easily wipe away. You can also soak kettles and other kitchen items in Coca-Cola to remove scale and build up.

Clean bugs from your windshield

Another way Coca-Cola can aid in your car care is by removing bugs and gunk from your windshield. Soak a cloth in coke, then rub across your windshield. Just be careful not to get any on your paint job.

Remove rust from your car

Coca-Cola is also useful when removing rust. The simplest method is to dip crumpled tinfoil in Coca-Cola, then give the item a scrub and you should be rust free.

Loosen rusty bolts

Similarly, use Coca-Cola to loosen up a rusty bolt. Simply unscrew the bolt half a turn and pour on Coca-Cola. Let it sit, then give the metal a wipe. The bolt and screws will be one hundred percent in no time.

Remove stains from your fabric

Surprisingly, Coca-Cola is incredibly helpful when removing stains from clothing and fabric. Coke will easily remove grease stains, as well as blood spots. Remember that Coca-Cola itself is brown, so stains on light fabrics might be better removed another way.

Remove oil spots

Another way to use Coca-Cola is to remove oil stains from cement. Whether it’s your garage or your driveway, soak the stain in Coca-Cola for a few hours then hose off.

Relieve jellyfish stings

Should you be unwilling to neutralize a jellyfish sting the traditional way (with urine) pouring Coca-Cola on the sting will also do the job.

Clean your car engine

Coca-Cola is also an effective ways to clean your car engine. Believe it or not, Coke distributors have reportedly been a fan of this technique for ages. 

Use it in cooking

Coca-Cola is also a fantastic addition to many recipes. Using Coca-Cola to cook pot roast or steaks in will easily tenderize the meat for you. Mixing Coke with ketchup or barbecue sauce also makes for a delightfully sweet glaze.

Clean your old coins

Another way to use Coke to clean is to soak tarnished coins in the soda. About ten minutes should be enough to get rid of the muck.

Clean your tiles

Incredibly, Coca-Cola can also be applied to tiles to effectively clean grout. Let Coke sit on the tiles that need cleaning for a few minutes, then wipe away.

Supercharge your compost

Coke is also an impressive way to speed up your compost. The sugar in Coca-Cola feeds micro organisms, plus the acidity will help your compost break down faster.

Remove gum from your hair

Coca-Cola can also help you avoid a major hair disaster. If you have gum stuck in your hair, dip the gum into a small bowl of Coke and let it sit for a few minutes. The Coca-Cola breaks down the gum, allowing you to wipe it off.

Fade unwanted hair dye

Similarly, if you made a mistake with your hair dye, Coca-Cola comes to the rescue. It’s probably best to get in the shower first, then pour Diet Coke over your hair. Let the soda sit for a few minutes, then wash your hair like normal. This method is effective in removing temporary hair dyes, but will likely only fade professionally applied dyes.

Clean marker stains

Coca-Cola is also an easy way to remove marker stains from carpet. Apply a small amount of Coke, scrub the spot, then clean with soapy water. Again, remember that Coca-Cola is brown, so removing stains on white or light-colored carpets might be better achieved with another method.

Clean your toilet

Coca-Cola can also help you clean elsewhere in the house. To easily clean a toilet, pour Coca-Cola all around the bowl and let it sit. There’s no need to scrub, simply flush and your toilet should be sparkling clean.

Feed your plants

Coca-Cola is also a surprising way to add a little extra life to some flowering plants. Particularly with azaleas and gardenias, adding a small amount of Coca-Cola to the soil can deliver nutrients your plant may be low on.

Get rid of bugs at a picnic

The last of our unusual uses for Coca-Cola is to safeguard your picnic or outdoor lunch from pests and wasps. Simply pour a small cup of Coca-Cola and set it out about a half hour before you start to eat. By placing the cup away from your site, bugs will be drawn to the soda and not your lunch.
