Google’s Free Public DNS

I know you’re a big fan of openDNS and I saw this article about Google free public DNS.http://www.appleinsider.com/articles/09/12/03/google_launches_free_public_dns.html

Maybe some would find it tragic that I actually got excited about this news. :-p

We do put OpenDNS‘s servers — 208.67.222.222, 208.67.220.220 — in everyone’s network configs, but I’ve always been a mite concerned that the service could shut down. I gotta assume there’s less chance of that with Google.

The reaction to Google DNS blogged by the founder of OpenDNS is brief but really instructive, and it allays my concern about their longevity. Also, he makes some good points about how their service is different.

Mac becomes more like dog

I used to use Salling Clicker with my Treo and my Sony Ericsson for remote control over Bluetooth. It was really cool that my Mac would recognize when my phone was nearby, and would start syncing or do other stuff that I thought handy. The iPhone doesn't do very much with Bluetooth, but this developer has figured out something pretty useful. Not bad for $8.

Airlock allows your Mac to lock itself, plain and simple. Using your iPhone or iPod Touch, Bluetooth, and a smidgen of pixie dust, Airlock determines whether you're near your computer. When you leave the room – poof! – your Mac locks itself. “And when I come back?” You guessed it: your Mac unlocks. You can also customize Airlock to perform specific actions as you come and go – have your computer talk to you, log-in or out of iChat, walk the dog, and such.
 
(By the way, this is yet another tip I got from the picks by the guys on the MacBreak Weekly podcast (iTunes link). They're always mentioning useful stuff, and they maintain a nicely rounded perspective on the Mac, while still being obvious fans.)

Please welcome our new contributor

I'm really pleased that my dad, Bob Marcus, has accepted my invitation to post to the J2 Blog.

I wouldn't be the geek that I am without my dad. One day, when I was a teenager, he showed me some of the code for the medical-records databases he had written in the 70s. He kept up the project — mission, really — clear through to his retirement: to design an electronic medical records system for OBGYNs that would be the most comprehensive and useful for doctors and staff. He worked in different platforms, and with different vendors, and over time he got to see his industry finally embrace a technology he had long known was inevitable, and had been evangelizing for years. 

Upon retiring in 2004, and being freed from developing on the Windows platform, Dad decided to go Mac. I was all kinds of honored. PowerBook G4 in hand, he quickly got excited by web design, and the then-nascent medium of podcasting. Before long, he redirected his programming expertise to another new idea: music-paced running. He developed a website at jogtunes.com, with a SQL/PHP database of playlists composed by beats-per-minute, selling the tunes in iTunes and Amazon and Rhapsody; then a podcast (iTunes link), based on the same idea, but using independent, "podsafe" music. Now he DJs the workouts of thousands of folks a week, all around the globe. Come on, that's freakin' cool!

Dad had Datapoint terminals in his office. He took me and my brothers to a computer convention, where we witnessed an Apple II playing color images in sequence, almost like a movie! Dad got me a Sinclair ZX81, on which I honed my own [sad] programming skills, but more importantly developed geek cred. and the moment in 1984 when he said "Let's go check out one of those new Macs for a test drive!" — he kicked off my career.

Henceforth, I think I'll use his podcasting handle, Dr. Bob. Bob has been putting iTunes, GarageBand, and Mac web development through much harder paces than I am ever going to, and I know that his posts, besides being spontaneous digital nakhes generators, will be priceless additions to this collection of tech tidbits in our little corner of the interwebs.

Do we need a server?

I remember the first time I became aware of the word “server.” For some reason it sounded very mysterious, something that required arcane tools and deep learning with the elves in the mountains.

Eventually, I came to figure out that a “server” is simply a computer — any computer — that provides “services” to other computers. If you computer can share its files, it’s a file server. If you turn iTunes music sharing on, your computer becomes a music server. If you have a shared printer, your computer has become a print server.

Apple makes it super-easy to turn any Mac into a server by going to Apple menu > System Preferences > Sharing (or Spotlight “sharing”) and turning on any of the services you need. Your Mac will then show up in the “Shared” section of any Finder window. Boom, you got a server.

That said, when most people refer to a server, they’re talking about some machine that doesn’t do anything else, a box that’s tucked away, maybe in a rack or a closet, and always on, with a nice big battery backup, maybe a few hard drives, and fans like a wind tunnel. And most servers on the planet should be that robust; I need Google’s mail servers or my web server at GoDaddy never to go down, or at least, if they do need a reboot, that there’s a backup server waiting next to it in the data center to kick in as soon as its brother goes down.

A lot of businesses have one or more servers at the workplace. Sometimes they’re just file servers, a central repository for the documents that everyone needs access. Sometimes they’re also mail servers. Running your email through a Windows Exchange Server housed in your office was a popular option among Microsoft-certified professionals at a time when outsourced email hosts weren’t as flexible or affordable as they are now.

Again, to be clear: most organizations with fewer than 40 or 50 users would be wasting precious money to purchase Microsoft Small Business Server, when they can sign up with Google Apps either for free or for $50/user/year (40 users for $2,000/year, versus an easy $5,000 just to install and configure, not to mention maintain and troubleshoot, a Windows Server).

So let’s say you just need to share documents among more than 10 people, and you need them available all the time, and time without them costs money. Until this last Tuesday, the best value in a server-class machine was Apple’s Xserve

Way powerful, way configurable, way manageable – The specs on each generation of Xserve have been increasingly impressive, and it starts at a $3,000 base price that has always included the $1,000 OS X Server (unlimited-client; Windows Server starts at 5 users, and costs $50 per user after that). Most Xserve buyers should expect to pay at least $5,000-6,000 for a properly configured unit with 3 hard drives, a redundant supply, external backups, and if one is smart, the AppleCare server support plan. I can usually have a new OS X Server set up, with a few connected workstations, in under 6 hours.

A Bit of History

Apple’s server software (a.k.a. server operating system, or “OS”) is Mac OS X Server, now in version 10.6 (a.k.a. Snow Leopard Server). For so many years, AppleShare server products (still promoted in Australia!) distinguished themselves in IT discourse only by being pretty crappy. It just didn’t have the moxy that system admins were used to getting from Microsoft Windows NT or its descendants. And when OS X Server came out — it was actually the first release of OS X — it was really more of a theory than an operating system. Even though it was built on the well-established UNIX platform, it was buggy and slow, and it had these really weird quirks that made it very frustrating. Certainly it was impossible for an IT administrator to recommend that a business rely on this system for their day-to-day operations. 

Today, OS X Server has evolved into a robust, stable platform, one that’s easy to set up, easy to expand and scale, and like the basic OS X (we might call it “OS X client”), Server is impressively compatible with other platforms and standards. Since OS X Server and the Xserve came into their own, and given products such as Xsan and Final Cut Server, Apple is officially a viable player in the world of business and enterprise.

The Value of a Server

Is all of this worth several thousand dollars to your organization? It sure can be, once you realize the other things you can do with a server, which I’ll get to in a second. First, I have to say that this article is inspired by Apple’s announcement today of a Mac mini server. This $1,000 box is now potentially my favorite item in the entire product line, as I think it spells great things for businesses large and small. Considering that Apple has now slashed the price of the software itself to an unbeatable $500 for unlimited users, buying into a Microsoft server product now just seems unwise and wasteful.

So what can you do with a server? Check this out:

  • File Sharing, Network homes, and Backups: We can tie all of your Macs to your server so that the “home folder” for each user account is stored on the server. This means anybody can use any Mac in the house, and use their own desktop and files and email and settings. And if one computer dies, you put a new one in its place, log that person in, et voila! You’re back in business.

    • Portable Home Directories: This includes laptops, which can sync their accounts to the server, backing themselves up whenever they’re in the office.
  • Software Updates: We can have the server download all your software updates, and the administrator can pick and choose which one should be rolled out. When someone logs in, even a non-admin user, they’ll have an opportunity to install the approved updates, and their Mac only has to go across the office network, not all the way back to Apple’s servers.

  • Preferences: You can choose apply settings for all users in one fell swoop: adding a printer, adding items to the Dock, or automatically mounting a share point [definition]; or perhaps restricting things along the order of parental controls, or preventing or allowing certain applications.

  • NetBoot & NetRestore: You can actually have your Macs start up from a disk image [definition] on the server. If you need to update all Macs, just update the image. A variation on this idea is to have the Macs install themselves from a central image.

Of all of these possibilities, certainly it is having a centralized place for data storage and backup, and for backing up your workstations, that makes in-house servers attractive, and possibly essential, for any organization of any size. 

Keep your head in the cloud

I say possibly essential, because there are now services on the internet, such as Google Docs and DropBox, that have begun replacing server hardware for many people. I am all in favor of using these online applications, with the sole caution that we don’t rely on them to back up our data. It is crucial to keep an on-premises copy of every piece of data that means anything to you, just as keeping an offsite copy is de rigueur in any comprehensive backup scheme. I use a Firefox plug-in that downloads all my Google docs, and I backup that folder to an external hard drive.

But if you need fast, reliable storage that all your computers can see, to centralize your data and keep your Macs humming in unison, there’s nothing like a properly configured OS X Server.

Mac mini is finally a proper, officially sanctioned OS X Server

This is just too freakin’ sweet. Apple has just ripped Windows Server a big one. This $1k gets you an unlimited-client license for OS X Server (which not 3 months ago cost you a full $1k itself), two software-RAID-able hard drives, and plenty of juice for most small-business needs.

Just for comparison, Microsoft Small Business Server starts at $700 for a 5-user license, and that’s just the software. And OS X Server is way easier and quicker (thus cheaper) to set up.

I’m further impressed that, on the configure-to-order page, Apple points directly to a 4-disk Promise RAID device that should be almost as cool as a Drobo.

This box should do a lot to spread OS X Server all around the world, which is great for the whole Mac admin community.

    When Your Mac Is Really Screwed Up

    Facebook msg, Subj: : ( 
    Suddenly there’s a 2″ thick (nearly opaque) white bar running down the center of my iMac screen. It’s distressing me. And of course my AppleCare Protection Plan recently expired. : (  What do you charge for a diagnostic look-see?  Or is this one of those problems that can’t be fixed?  

    I hate to say that’s almost certainly a hardware issue. The first step is to take it into the Genius Bar for their free diagnostics. (Make a reservation here for the North Star store.) Be prepared to leave it for a while, as they have fairly deep diagnostics that they can leave running, possibly even overnight in the case of hard-to-find RAM problems. 

    They’ll be able to tell you what’s up, and they may actually have a reasonable fee to repair. If not, they’ll probably tell you to take it to MacTLC. They will do a fine job, though if it’s a logic board replacement, you would need to be ready to a fairly hefty fee. You can find cheaper repairs on the internet — google “MacBook repair” for some examples — but you may not want to ship a desktop. What model do you have?

    I have an Intel iMac, which I purchased in May 2006.  Thanks so much for all your advice, J. I didn’t realize that I could take my computer into the Genius Bar for free diagnostics. I was already resigned to having to take it into a local shop for a $55 look. 

    My pleasure. I have only just recently heard that Apple sometimes charges a flat, fairly low rate to fix out-of-warranty machines, so it might not be that painful. If you would post a reply on my blog or on Facebook as to what they tell you, I’d be much obliged.

    Meanwhile, tell me: do you have a good, solid, daily backup for your iMac? If not, then, while you’re at the Apple Store (you need to make a reservation online), please pick up a LaCie Quadra 500GB or a G-Tech. Here are my typical suggestions for backup software, if you don’t yet have Time Machine in Leopard or Snow Leopard. 

    It’s worth iterating my post about the expectable life span of your Mac:

    After 3 years, you should have a new computer in your budget. After four years, be ready and willing to lay down some jack for a Mac. After five years, your Mac is past its prime, and will not be up to whatever awesome software Apple and other developer/magicians will have concocted.

    Keep me posted!
