A friend of mine recently posted on Twitter an image like the one above. Very logically he posed this question… How does 3.65 + 0.35 = 3.75? Is this some strange new cult of Apple mathematics? There appeared to be missing 256MB of RAM. Concerned for my friend’s memory loss and a bit puzzled myself, I opened my Activity Monitor. You can see, I had exactly same result. Being the Mac geek that I am, I didn’t panic. I figured there had to be a logical explanation. Maybe this was like hard drives where they say 1 TB on the box, but in reality you get less. That happens because when marketing the hard drive they base the numbers on 1GB equaling 1,000 MB instead of the actual 1024MB that it should. In the case of my RAM that wasn’t it. So what gives?

A quick Google search revealed the logical answer. It’s something I should have realized immediately but didn’t. See, I have a newer 15″ Macbook Pro with an integrated NVIDIA 9400M GPU and it uses… You guessed it. 256MB of shared RAM.

Mystery solved.

Well, here’s a cool little trick I ran across while trying to find a way to hide the menu and scrollbars in Mac OS X. This one is a Terminal hack that you can perform in Mac OS X Snow Leopard to get folders in Quicklook preview to show up with transparent covers. This gives you an “x-ray” style view of the icons of items inside that folder. Pretty neat. Here’s a little video on how to do it along with step by step instructions after the break:

Step-by-step
1) Launch Terminal (Applications–>Utilities–>Terminal)
2) Type in the following command:

defaults write com.apple.finder QLEnableXRayFolders 1

3) Control+Option+Click the Finder icon in the dock and select ‘Relaunch’ to restart the Finder.
4) Select a folder in the Finder and press the spacebar to open it in Quicklook.
5) The folder icon should now have a transparent cover and you can see the icons of items inside the folder

Secrets – The GUI Method
1) Go to the Blacktree Site and download Secrets
2) Install Secrets. Double-click the .prefpane file and say OK when it asks if you want to install the Preference Pane.
3) Open System Preferences–>Secrets
4) In the ‘Top Secrets’ section check the box next to ‘Show X-ray folders in QuickLook’.
5) Click the ‘Quit This’ button to quit the Finder.
6) Click the Finder icon in the dock to relaunch the Finder.
7) Select a folder in the Finder and press the spacebar to open it in Quicklook.
8) The folder icon should now have a transparent cover and you can see the icons of items inside the folder

After mentioning on Twitter that Apple doesn’t support momentum scrolling on their new Bluetooth Magic Mouse under Leopard:

a helpful listener sent me a reply with this handy Terminal command to enable it.

defaults write com.apple.driver.AppleBluetoothMultitouch.mouse MouseMomentumScroll -bool true

After entering the command above into the Termial and hitting enter, simply turn Bluetooth off and then back on to update the setting. After that scroll away with full momentum in Leopard.

To change things back issue the same command, but rplacing the last word ‘true’ with ‘false’ and turn off and back on Bluetooth again.

iPhone 3.0 has brought some fantastic new features that are well known like Cut, Copy & Paste. However some smaller tweaks have been made to the operating system that provide a better user experience. To me most of these changes effect Podcasts. For example you now have easy access to the speed controls and a 30 second skip-back button incase you missed something. Fantastic for shows that go in-depth on specific topics like Security Now!

Also seen in the screenshot is the little envelope icon. This button allows you to share current podcast with a friend via an iTunes Link. This does not work on podcasts not featured in the iTunes store, so if you’re subscribed to an RSS feed you are unable to share.

The feature most important to me for daily use isn’t MMS, but the ability to quickly see the remaining battery life. My way around this was a little app called Free Memory, which has the auxiliary feature of telling you the battery life percentage. The app is still worth keeping around if you own an original iPhone or an iPhone 3G and for the ability to free some memory on your device. For iPhone 3GS owners, you now have a nice little option to show the battery life in the top tray of the iPhone.

To access the battery life option, head over to your settings button on the iPhone home screen. From there tap General, then tap Usage, and there will be a slider button on the top. This option is turned off by default and hidden in a screen most people never make there way into.

iPhone OS 3.0 has been great to me so far, but my big excitement is over the speed of the new 3GS which I was reluctant to pick up at first. A full review of my 16 GB 3GS White will be coming up soon. In the meantime, what features of the iPhone 3.0 update have proved useful to you?

Updated: Added text to help clarify that the battery percentage feature is an iPhone 3GS only feature. Thanks to the astute folks in the comments for pointing this out.

So I have only played with the iPhone 3G S for few hours, but one of the cool features I was looking forward to trying was the new Voice Control. Only one problem. I had trouble figuring out exactly how to make it work. In most cases I am usually able to figure out how new iPhone features work. For this feature, I had to get some help from Apple’s support site and the iPhone 3G S User Guide. To save you some time, here is how to get this feature up and running on your new iPhone 3G S along with the command you can use to make it go. If you want to consult the manual yourself, here is the link (PDF) from Apple’s support site.

To activate the Voice Control feature:
Press and hold the Home button on your iPhone or press and hold the center button on the iPhone headset. After a second or two the Voice Control interface should appear and you’ll hear a beep indicating it is ready for your command.

Voice commands you can use:

• Call a contact: Say “call” or “dial” plus the name of a person in your contacts to call that person. If they have multiple numbers the iPhone will prompt you for which number, i.e. “Home” or “mobile”.
• Dial a number: Say “call” or “dial” and then the number
• If you make a mistake: You can say “wrong,” “not that one,” “not that,” “no,” or “nope.”
• Play music: Say “play” or “play music.”
• Pause music: Say “pause”
  or “pause music.”
• Change songs: Say “next song” or
  “previous song.”
• Play an album, artist, or playlist: Say “play,” then say “album,” “artist,” or “playlist” and the name.
• To enable shuffle: Say “shuffle.”
• Get current track info: Say “what’s playing,” “what song is this,” “who sings this song,” or “who is this song by.”
• Use Genius: Say “Genius,” “play more like this,” or “play more songs like this.”
• Cancel Voice Control: Say “cancel.”

That’s it. I have to say the Voice Commands work pretty well right out of the box (at least with my “average” anglo saxon US voice). About my only complaints are that you have to constantly go in and out of Voice Command mode using the hold button technique described above and that the default voice is a bit tricky to understand at times. No OS X “Alex” here. That said it’s nice to have voice control on the iPhone (finally) and I look forward to get getting better in future updates.

Frequent emailer to the Maccast Robert noticed a little something in the recent iTunes 8 update. Something that has become a very common and un-Apple like annoyance in iTunes updates. For some unknown reason Apple re-designs or moves significant functionality between versions of the software. With iTunes 7 the one that got me was them moving the “chapter” options for enhanced podcasts to the menubar. In iTunes 8 the most confusing example is their removal of the 3 tab options (General, Importing, Burning) from under the ‘Advanced’ menu in the iTunes preferences. iTunes 8 simply has one ‘tab’ of Advanced options. The other two former ‘tabs’ have mysteriously vanished. Or have they?

The import and burning options have actually been moved to other locations. In case you find yourself searching for these options, like I have been over the past few days, here is a quick overview of the process for setting these options in the latest version of iTunes.

Importing Settings

To set the import settings do the following:

1. In iTunes 8, choose ‘Preferences’ from the ‘iTunes’ menu (Command + , ).
2. In the ‘General’ tab, press the ‘Import Settings…’ button.
3. In the dialog box set up your desired import format, bit rate, etc. and click ‘OK’ when finished.

CD Burning

To burn a CD do the following:

1. In iTunes 8 create a playlist. If you want to burn a whole album you can drag the album from the new ‘grid’ view over to the playlist section in the left sidebar. This will create a new “playlist” for that album. Now select the playlist you want to burn.
2. In the lower right corner of the main iTunes window click the ‘Burn Disc’ button.
3. Now in the dialog box set up your desired disc burning options. You can choose the burning device and speed, select the disc format, set the gap between tracks, etc. Then insert a blank disc and click ‘Burn’.

I am not sure why Apple chooses to move major functionality between versions like this. I personally find it annoying, but at least now you know what has changed this time around.

Nova Media today announced introduction of a new version of their FoneLink app, version 2.0, which gives Mac users a really nice tool to keep their mobile phone in sync with contacts, calendar, and media—in ways that iSync can’t. If you know how iTunes lets you sync with your iPhone or iPod, this is the closest thing to it.

Divine Robot has developed a new tool that allows Sony Ericsson mobile users copy and synchronize songs from their iTunes library to their phone.

Mac OS X’s iSync is good for synchronizing your contacts and calendars to your mobile phone, but not so much for your music. iTunes will generally only sync your music with iPods, some older MP3 players, the Motorola ROKR phone, and the iPhone. Not so much help if you want to play songs from your iTunes library on your phone. That’s where the helper-app EasyListening comes in.

Start up the app and plug-in your supported Sony Ericsson phone via USB. Up pops a brushed metal window that looks iSync, showing the name and description of your phone. From there, fire up iTunes and select individual songs or a whole playlist (not supported by all phones) and then drag them to the EasyListening window. You can also use EasyListening to sync songs to a Memory Stick card.

Until the SDK comes out I’m stuck in envy of my friends who can play games like Labyrinth and use native apps such as iFlickr, iFlix, and MobileChat. Getting used to web apps can be difficult, but I’ve spent a fair amount of time sifting through the obscene amount of web apps that have little or no functionality to find the best.

Instant Messaging: There are a few options here but Meebo easily provides the best experience. It is essentially the same as the other options, however with Meebo you can use your existing account to log into multiple IM accounts at the same time. This however has a secondary purpose that makes it so great. When you’re instant messing with Edge there is a good chance you will get disconnected and miss parts of the conversation. Meebo enables logging when you sign up for an account, so you never miss any part of any conversation, and can refer back to it  at any time. http://meebo.com – automatically loads iPhone version upon visit.

I am not sure how long this has been around in Firefox, but at least in the latest version of Firefox 3 beta for Mac I stumbled cross this trick. This morning while working on other things I accidentally dropped a folder from the Finder into a Firefox window I had in the background. Imagine my surprise when I saw what you see in the image above. Firefox displayed the contents of the folder in a file browser like structure. I could navigate up and down the directory tree and there was even an option to turn on and off viewing of invisible files. I did notice that it won’t allow you to navigate to the root of your hard drive, but files that can be viewed normally in a browser (like image files or Quicktime movies) will show up right inside Firefox. They have also done a very nice job with the user interface. It sorta reminds me of .Mac.

Now normally this shouldn’t be surprising considering that many browsers can view file systems on remote servers (if the feature is turned on and allowed in the server configuration), but this works locally. I also know that Internet Explorer on Windows has been able to do this trick for years, but this is on a Mac. The trick also does not work in Safari, at least not in the current version of Safari running under OS 10.5.2.
