If you would like to see the folder sizes on the Mac, you can do so easily by enabling a folder size calculation when looking at directories in the List View of Finder in Mac OS X.

What this trick does is show folder sizes on the Mac, calculated in megabytes, kilobytes, or gigabytes, depending on the total storage size taken up of each individual folder found on the Mac. In my opinion this should probably be enabled by default since it is a popular feature, but the standard Mac OS X list view setting is to not display the size of folders and their contents. Alas it’s no big deal, this is easily changed with a preference adjustment.

If you use SSH even somewhat often, it would benefit you to setup a basic SSH config file. If you’re curious why, would you rather type something like this:

ssh -p 6851 user@servername.domain.com

Or just type:

ssh name

I know what I’d rather do, so let’s get this working. I’m going to use nano editor because it’s user friendly.

Launch the Terminal and type the following:

nano ~/.ssh/config

You’ll probably have a blank config file and that’s fine, so here’s what we’ll add to it:

host shortcutname
HostName server.domain.com
Port 5555
User username


Here’s how this might look:

I keep things indented to make them easier to read but it’s not necessary. Once your server and login info is inputted, hit Control+O to save the file, then Control+X to quit out of nano.

Now you can just type the shorthand to connect to a server, such as ‘ssh osxd’ and the full hostname, port, and username will be included for you.

There are many more possibilities with SSH configs, if you want to check out more options just look at the manual page with “man ssh_config”

Check out some more command line tips while you’re at it.

In a recent speech, Steve Wozniak compared tablets and the iPad to TVs, and suggests that the iPad is the culmination of what Steve Jobs has long wanted to create at Apple; a consumer friendly appliance for everyone.

Here are some of the better quotes via MacWorld:

“The tablet is not necessarily for the people in this room,” Wozniak told the audience of enterprise storage engineers. “It’s for the normal people in the world,”

And here’s the quote on Steve Jobs’ long awaited vision of the iPad as a consumer appliance:

“I think Steve Jobs had that intention from the day we started Apple, but it was just hard to get there, because we had to go through a lot of steps where you connected to things, and (eventually) computers grew up to where they could do … normal consumer appliance things,”

I definitely agree with the idea of an iPad (or tablet) being the perfect PC for a regular user, but it’s obviously much more than that too. Apple touches on this well in their new iPad 2 “We Believe” commercial, and we’re only at the beginning of the platforms life.

If you want to quickly backup an entire website through FTP, the absolute easiest way to do this is through the command line using the wget command. In fact, you can backup an entire site (or whatever else is on the entire FTP server) with a single command string.

If you get easily distracted by things sitting around in the background, HazeOver might be for you. It’s a free utility that casts a shadow on all inactive windows, in other words, any window that isn’t in the foreground will be “hazed over.” Windows actually phase in and out of the shadow so it’s a neat effect even if you aren’t using it to minimize distraction and just want some additional eye candy on your Mac.

Oh and if you use multiple monitors on your Mac, it will only cast shadows on your primary display, but the developer is working to fix that bug.

You can download HazeOver for free from the developers site.

Apple has started to air the first iPad 2 commercial, it’s a bit different than their past TV ads but it’s still undeniably Apple. The commercial declares “This is what we believe; technology alone is not enough” it then goes on to describe the iPad 2 a bit, but it’s real message is that while the iPad 2 is amazing, it’s the people using it that make it so special.

The commercial kind of reminds me of the recap video that was played at the iPad 2 launch event, which was much less about the iPad and more about how people are using the device and how it has changed their lives. It’s a good message and I like the videos, certainly more than the recent iPhone 4 commercials.

Apple certainly hasn’t needed to advertise the iPad 2, it still sells out at every new shipment and finding one is a challenge. If you’re still looking (hey me too!) you have to check iPad 2 stock in your region by calling resellers. They all seem to sell out soon after getting a shipment, so moving fast is essential.

In a somewhat hidden feature of iTunes, you can display a music spectrum analyzer in place of the iTunes song info. All you need to do is click on the little play icon in the song info area, it’s highlighted below with an arrow pointing to it:

This has probably been around for a while but I just stumbled upon it accidentally. I had never thought to click on that button, I long assumed it was a play and pause song icon.

Mac OS X Lion Developer Preview 2 has a new version of the default Mt Fuji wallpaper. The new picture shows some clouds in the foreground and the mountain itself has a bit less snow on it, creating less of a contrast. As usual for Apple’s default desktops, it’s absolutely beautiful, and it makes a great desktop background.

Click the image above or here to download the full version, it’s a rather large 3200×2000 pixels.

Here they are alongside each other, the new Fuji Mountain default is on the left, and the old Lion Fuji wallpaper from the first Developer Preview is on the right:

Apparently the Lion Space wallpaper from Versions is also different in the new Developer Preview as well, we’ll see if we can track it down.

Thanks for sending this in S.E.!

If you’ve been a Mac user for a while, you’ll remember the Apple Extended Keyboards. They were very responsive and made a wonderfully crisp clicking sound as you typed. If you’re still in love with the old ADB powered Apple Extended Keyboard I don’t blame you, and you can reignite that old flame by using that very keyboard on an iPad or iPad 2. Here’s what you’ll need to do this:

Apple turns 35 years old today! The company was created on April 1, 1976 by Steve Jobs, Steve Wozniak, and Ronald Wayne, it was based out of Steve Jobs parents garage, and their first product was the Apple I encased in wood that you can see above. Yea, that’s not an April fools joke, the first Apple computer was made out of wood.

Fun facts about the Apple I:

• Apple I was first demoed in April of 1976 at the Homebrew Computer Club in Palo Alto, California
• It went on sale in July of 1976 for $666.66, the unusual price was chosen by Steve Wozniak because he liked repeating numbers
• CPU clocked in at 1 Mhz
• RAM was 4 KB, but was upgradeable to 8 KB or even 16 KB via expansion cards
• Apple I is now considered a collectors item, one of the computers recently sold for a whopping $213,600 at a London auction

Here’s one of the original advertisements for the Apple I:

It’s April Fools today, which means the world is full of pranksters and the internet is largely useless and filled with outrageous stuff. We’ll do our part but try to still be useful (sort of), so with this in mind here are some Mac pranks that are fun to pull on April Fools, or any day:

You’ve seen the iPad 2 show off a childs fridge art, now the iPad is acting as a $500 grocery list, stuck magnetically on a refrigerator. Amazing use of this piece of technology. What’s next in the realm of innovation? Is there any other amazingly great things you can do with an iPad and it’s magnetic smart cover?

No this is not an April Fools joke. Select Apple customers are being sent email invitations to sign up to be testers for Mac OS X 10.7 Lion. No developer account is required, but you’ll have full access to the current developer releases of Lion.

Free access to Mac OS X Lion sounds almost to good to be true, so what does Apple want in return? Other than your confidentiality, they want users to actively participate in the program by using Lion on a regular basis, providing feedback, and filing bug and crash reports when they occur. Obviously the goal is to expand the end-user testing beyond just Mac developers.

Fittingly, the program is called AppleSeed, and if you were lucky enough to get an invite, you just login, sign your confidentiality agreement, and then you can go about downloading Mac OS X Lion Developer Preview 2. If you’re going to sign up, you might want to consider installing Mac OS X Lion on a separate partition so you can maintain your existing Snow Leopard installation.

If you didn’t get an invite from Apple, there’s currently no way to opt into the program, but you can always sign up to be a Mac developer and download Lion through there.
