I came across a neat tip on “*Lifehacker*”:http://lifehacker.com that makes browsing the iTunes Store much easier. I often find myself jumping back and forth between multiple app descriptions as I try to decide between several apps that do similar things.

Apple has yet to implement any sort of tabbed browsing, so when you find an app that you want to check out and compare, just drag the icon into Safari (or other browser if you’re a Firefox or Chrome user). You should be able to drag multiple app icons into your browser, and each will open in its own tab — making it much easier to toggle between them!

While having in-house servers used to be standard for all flavors of businesses, more and more companies are turning to “Cloud Computing” or Software as a Service (SaaS) for their server needs. SaaS models used to be thought of as less secure and riskier than in-house servers. Now, with fully encrypted cloud options held at secure locations with redundant backups and robust networks it’s almost a no-brainer to make the switch to SaaS.

We’ve recently become “*Google Apps for Business*”:http://www.google.com/intl/en/enterprise/apps/business/ resellers and we couldn’t be more excited about it! We’ve helped several businesses move from their existing mail, calendar, contacts and file sharing servers over to Google Apps and we’re in the process of making the switch ourselves.

With the low price of $5/user/month we estimate that we’ll save thousands a year between hardware and maintenance costs. Not to mention, Google’s interface heavily promotes collaboration within an organization by providing easy-to-use tools that are intuitive and interface beautifully with Apple’s Mac and iOS. On the administrative end, I’m extremely impressed with the amount of tools I have at my disposal to ensure our company’s information remains secure and well-managed.

If you’re thinking of making the switch to a SaaS system for your company’s needs, I highly encourage you to go with a trusted source, like Google. I’d also caution you to keep in mind that even with Google’s robust datacenter, it’s important to have a secondary backup of your information. Google guarantees uptime of 99.9%; that’s still not 100%. This is why we’ve also partnered with companies like “*Backupify.*”:https://www.backupify.com “*Backupify*”:https://www.backupify.com can create a secondary copy of your data and they host it on Amazon’s secure servers __plus__ you have the option of making a local backup on your own servers.

In last week’s article, I mentioned a special command that requires a password to perform certain tasks. This week I’d like to talk about that command a little. It is called *sudo.* It is both an acronym for the expression “Super User DO” and also the “su” and “do” commands put together.

The first part, “su”, is the power part. It enables you to enter commands as what is known as the “superuser” or “root” user. The superuser can do anything, which is both powerful and dangerous. When you enable as a superuser you will be warned up front that you are now capable of destroying your system with ease. While you are always required to enter your password when enabling as a superuser, you only get the warning once. After that, they assume you are on board with being responsible for your system. The warning is pretty dry in current incarnations of the OS, but in the past the text looked like this:

bq. __We trust you have received the usual lecture from the local System Administrator. It usually boils down to these two things:__

# Respect the privacy of others.
# Think before you type.

Kind of friendly and humorous. (And, kind of sad that level of humor has made way for more straightforward notices.)

On to the second part: “do” is what it seems like. It is an action command. So together, you get “sudo” or SuperUserDO. One might ask why bother to use “sudo” when you could just use “su” and then type in your commands? From a caution point of view, “sudo” provides some benefits — it times out after 15 minutes, after which it requires you to enter your password again. So it’s OK to walk away and forget you were logged in as the root user, because after 15 minutes you revert to your normal status.

The “sudo” command is a great tool to accomplish tasks normally not allowed in terminal, such as changing permissions and ownership of certain files and moving things you normally couldn’t. For more information, “*click here*”:http://en.wikipedia.org/wiki/Sudo to see the wikipedia page. Next week we’ll look at some tasks that require the use of this powerful command.

Hello all,

The light is starting to have that pale look it gets this time of year and the days will soon be noticeably shorter. I love the fall for a lot of things…apples, Halloween, crunchy leaves, and the excuse to eat stew and thick soups all the time, to name a few. I actually enjoy walking through cold rain and wind while the leaves fall, because at the end, there will be warm cider or cocoa. That’s to come, though.

Did anyone hear the Apple released a new phone last week? I am joking of course–if you had not heard about it you would have had to be taped up in a cardboard box in a closet somewhere near the arctic circle. No matter what side of the love it/hate it iPhone debate you come down on, it seems likely that the iPhone is going to help drive competition and innovation in the phone market for a long time.

Anyway…there’s another Terminal article this week, plus more from our group of intrepid techs. Thanks for reading.
