Time to Discontinue the 13" MacBook Pro?

So says Cnet's Scott Stein, who notes that the original 13" aluminum unibody form factor, which debuted as a just plain MacBook in October 2008, is getting a bit long in the tooth. As Stein observes, that was before Barack Obama was elected president, Avatar hadn't yet been released, the iPhone was on its first refresh, and the iPad was still a year-and-a-half away.

Stein observes that since October 08, the 13" unibody has barely changed its appearance at all, although beneath its anodized aluminum skin, it's a completely different computer today with an Intel Core i processor, Thunderbolt, an integrated long-life battery, and a better screen, but you can plunk a 2008 13-incher down beside the latest 13" Pro and most people won't be able to tell the difference.

Indeed, Stein he concedes that he himself has leaned slightly toward the 13" Pro as the laptop of choice if one had to pick an all-around Apple computer, but he argues that few people use optical drives, and processor and graphics performance are roughly equivalent to the 13" MacBook Air, He suggests that making hybrid drives optionally available in the Air, a la some of the new PC Ultrabooks, would address his only misgiving about the Air vs. the 13" Pro. That's skipping over the Air's RAM limitations - you cannot upgrade system memory in any MacBook Air - a bit too blithely, but with Apple's entire notebook lineup due for replacement sometime this year, the 13" MacBook Pro is likely on the bubble.

WD Previews My Book Thunderbolt Storage System at Macworld | iWorld

PR: Western Digital demonstrated the ultra-fast data transfer rates of its My Book Thunderbolt Duo dual-drive storage system at the Macworld | iWorld show. Thunderbolt technology will dramatically improve workflow speed and efficiencies for enthusiasts and professionals dealing with large digital files such as video, audio and still photos.

WD My Book Thunderbolt Dual-Drive Storage SystemThunderbolt technology is capable of producing up to 10 gigabits per second* of throughput on each of two channels in both directions. Users can experience very fast read/write speeds especially during applications such as video editing, 3D rendering, and other intense graphics projects. To put Thunderbolt's speed into perspective, HD media creators will be able to transfer a standard size full-length HD movie in less than 30 seconds or backup an entire year of continuous music (approx. 8,600 hours of music) in roughly 10 minutes.

"Thunderbolt technology offers the speed needed for creative professionals and enthusiasts who produce, edit, or need quick access to large files, including HD video," says Jody Bradshaw, general manager of WD's consumer storage solutions. "During the demonstration, twin Thunderbolt ports show amazing flexibility while allowing daisy-chaining of up to six My Book Thunderbolt Duo systems or other high performance peripherals for an enhanced workflow process. The combination of storage, backup, and speed could make the My Book Thunderbolt Duo the only drive a creative pro would ever need."

Publisher's note: The My Book Thunderbolt Duo is not yet listed on WD's website. All current My Book Drives for Mac support USB 2.0, most support FireWire, and the Studio II also supports eSATA. The PC My Book Essential drive supports USB 3, which is not yet supported by Apple. dk

* Stated transfer rate for Thunderbolt is based on published specifications from Apple. Actual transfer rates when used with My Book Thunderbolt Duo will differ significantly based on system configuration. Performance testing by WD resulted in an average actual transfer rate for Thunderbolt of >250 MB/s on 6 TB systems and >225 MB/s on 4 TB systems. Gigabits per second (Gb/s) = one billion bits per second; megabytes per second (MB/s) = one million bytes per second

Trim Enabler Brings TRIM SSD Optimization to Mac OS X

Trim EnablerPR: Oskar Groth says Trim is must-have feature for most Solid State Drives. It not only increases data writing speeds, but it increases the lifetime of the SSD itself. With Groth's Trim Enabler, you can bring Trim support feature to Mac OS X. Its as easy as flipping a switch.

Trim Enabler can also analyze your drive and show information about its health and show lifetime statistics.

Trim EnablerFeatures:

  • Trim - With Trim Enabler, you can enable Trim for third party Solid State Drives in Mac OS X. Trim is a command that is executed in the background by the operative system when you delete files, informing the SSD that the blocks are no longer in use and can be deleted. By doing this, the SSD can avoid slowing down future write operations to those blocks.
  • S.M.A.R.T - Using the S.M.A.R.T monitoring system, Trim Enabler lets you view information that is relevant to the health of the drive. Solid State Drives do not last forever, but by using the S.M.A.R.T tool you can detect issues such as rapidly increasing amount of written data, and increase the lifetime of your SSD.

Trim Enabler is donationware.

Prey: A Powerful Recovery Tool for Tracking Your Missing MacBook

PreyPR: Prey lets you keep track of your laptop, phone, and tablet whenever stolen or missing - easily and all in one place. It's lightweight, open source software that gives you full and remote control, 24/7.

Silent but Deadly

Basically you install a tiny agent in your PC or phone, which silently waits for a remote signal to wake up and work its magic.

This signal is sent either from the Internet or through an SMS message and allows you to gather information regarding the device's location, hardware and network status, and optionally trigger specific actions on it.

Recover What Is Rightfully Yours

You can quickly find out where your computer is located, who's using it, and what he's doing on it, thanks to Prey's powerful reports system.

By marking your device as missing, Prey will gather all the evidence you request and send it either to your Control Panel account or directly to your mailbox, depending on the reporting method you choose.

They Can Run, but They Can't Hide

Besides gathering information, you can also trigger actions remotely, such as sounding a loud alarm or showing a message which will appear onscreen just in case you want the guy to know he's being chased at.

You can also wipe your stored passwords for security, or even lock down your PC to prevent access. In other words, you're in control.

There's two ways in which you can send Prey the activation signal and get the reports.

  1. Prey + Control Panel - Recommended for most users. You monitor your devices on Prey's web Control Panel, where you can watch new reports arrive and manage specific settings, such as changing the frequency for reports and actions. You can add up to three devices for free, and can optionally upgrade to a Pro Account in case you wish to bypass this limit.
  2. Prey Standalone - For advanced users who wish more control. In this case, reports fly directly to your inbox but you need to set up your SMTP settings, and more importantly, you must generate a valid web URL which will trigger Prey to wake up when deleted - otherwise Prey will keep sending reports on each interval! (For more information please check our FAQ).

Key Features

  • 100% Geolocation Aware - Prey uses either the device's GPS or the nearest WiFi hotspots to triangulate and grab a fix on its location. It's shockingly accurate.
  • WiFi Autoconnect - If enabled, Prey will attempt to hook onto to the nearest open WiFi hotspot when no Internet connection is found.
  • Light As A Feather - Prey has very few dependencies and doesn't even leave a memory footprint until activated.
  • Know Your Enemy -Take a picture of the thief with your laptop's webcam so you know what he looks like and where he's hiding. Powerful evidence.
  • Watch Their Movements - Grab a screenshot of the active session - if you're lucky you may catch the guy logged into his email or Facebook account!
  • Keep your data safe - Hide your Outlook or Thunderbird data and optionally remove your stored passwords, so no one will be able to look into your stuff.
  • No unauthorized access - Fully lock down your PC, making it unusable unless a specific password is entered. The guy won't be able to do a thing!
  • Scan your hardware - Get a complete list of your PC's CPU, motherboard, RAM, and BIOS information. Works great when used with Active Mode.
  • Full Auto Updater - Prey can check its current version and automagically fetch and update itself, so you don't need to manually reinstall each time.

Prey for iOS: The Inner Workings

The developers say that when they began drawing sketches, trying to imagine what the iPhone client for Prey would look like, it sure looked easy-peasy. But when they actually put their hands into it, they bumped into a number of things they had to sort out to make Prey work the way they wanted to, and of course, without breaking any of Apple's rules. So it took longer than expected, but the work is now done, and the wait finally over.

Prey is now available for iPhones and iPads at the App Store.* Open source, for free, tested, and ready to kick some burglar butt.

Here's a detailed explanation of how the iOS client actually works.

Keeping the Bird Watchful

The first thing that Prey does after being installed on a device is to add a hook for iOS Significant Location Change (SLC) service. This provides a way for Prey to be woken up when needed while using the least possible amount of battery.

What the SLC service does, internally, is to instruct the phone or tablet to poke Prey every time it connects to a different cell antenna. Once Prey receives that poke, it will ask the Control Panel about its status, very much like the desktop and laptop version does using Cron or CronSVC.

What comes next, you already know: If the device is marked as missing, Prey will begin to send new reports. If it isn't, it will simply go back to sleep and wait until it is poked again when the phone connects to another cell antenna.

So, the first difference with the laptop/desktop version is that on iOS the delay between reports and actions isn't a fixed, regular interval, but rather a semi-random one which is triggered when phones move from one location to another. Pro users ($5/month and up), however, do have On-Demand activation available in the Control Panel, that activates Prey in a glimpse without having to wait. Just as it works on PCs and Android devices.

Regardless of the way you sent the signal, either pull (interval) or push (On-Demand), Prey will send reports until the device is unflagged as missing in the Control Panel.

The main reason why Prey uses the SLC listener from iOS is simple: If it didn't, it would need to be opened by the person holding the device in order to work. This way, Prey can run silently in the background without giving any indication to the guy who took your phone that he's being chased.

The SLC service as well as support for background apps was added on iOS 4.0, so unfortunately Prey won't work on older versions of iOS. So if you're running an earlier version, it may be time to update!

Geo Module Accuracy

On iOS devices, Prey's Geo module includes an accuracy option which defines the frequency it will poll iOS for a new geolocation fix. As you may imagine, more accuracy means more battery consumption, but also a higher level of precision about your phone's current location.

We suggest you try different options so you get a better idea of the level of accuracy and the delay between reports. This is important, because when setting the accuracy to the lowest level, Prey may not get a new fix from the iOS in a while, so reports may take longer to arrive than expected. In the end, it all depends on how fast the person holding the phone moves around.

Front-Facing Camera Support

If your iPhone or iPad has a front facing camera, you'll be happy to know that Prey's iOS client supports it. This is how it works.

Prey for iOSAs soon as you push the On-Demand button, a predefined message will be displayed on your device (like the one on the right). Once the thief moves the slider, Prey will take a picture using the built-in camera, while a random bank page is opened showing a loading message. This way we can get the thief's attention so that he looks right into the camera lens when the picture is taken.

Unfortunately, Apple only allows the use of the camera when the application is running on the foreground, so the webcam module won't work if the application is sent to the background.

In other words, if you're not a Pro user, you'll need the app to be running in the foreground for the webcam module to work (i.e., the user must tap the Prey icon on the phone, which is not likely to happen). If you are Pro, however, you'll be able to send the On-Demand, push notification that, if opened, will raise the app to the foreground.

The bottom line is that if you want to take pictures remotely, you'll probably want to upgrade to Pro.

Camouflage Mode

If you installed the app on your device then you probably saw an option called Camouflage Mode. When Camouflage is enabled, a random image is shown instead of the Prey logo when the app's icon is tapped by the user. This is just to trick the guy into thinking that Prey is a game and not the reason of his future arrest.

What you can and probably should do is to move the Prey icon into one of iOS's subfolders (like Utilities, which includes the Clock and Calculator). This way the thief won't notice the application at a first glance.

* No, it isn't. Maybe it was, and maybe it will be again, but it's not there today.
