How To Update iPhone and iPad iOS Software Without a Computer

iOS will verify the download, patch the files, and restart the phone

Among the many new features in Apple’s iOS version 5 is the ability to update the operating system “over the air” without attaching it to a computer. An added bonus of updating in this manner is a smaller (and thus much quicker) differential or delta download. Today, Apple released the first over the air update to iOS, 5.0.1. Here’s how to trigger an automatic over the air update.

Sonnet Adds ExpressCard Support to Thunderbolt–Equipped Macs

The Sonnet Echo ExpressCard/34 Thunderbolt Adapter shows much promise (at a high price)

The Sonnet Echo ExpressCard/34 Thunderbolt Adapter demonstrates the power of Thunderbolt to bring flexible, high-performance connectivity to compact computers. But we are still in the first generation of devices like this, and it will be a while before prices drop out of the stratosphere.

Apple’s Thunderbolt Display Shows the Future

The new Apple Thunderbolt Display is much more than just a monitor: it's a demonstration of what Thunderbolt can do

Thunderbolt is important not because it is fast but because it extends the PCI bus outside the computer chassis. The next iteration of the Mac Pro could be as tiny as the Mac Mini, as long as it has two or more Thunderbolt ports and an expansion chassis for video and I/O cards.

Undocumented CoreStorage Commands

The commands are there to make CoreStorage do some cool things. But they don't quite work and aren't quite public...

I am pleased to note that CoreStorage, the volume manager in Mac OS X Lion, is much more functional than I had guessed, including a number of undocumented but seemingly functional commands for on-the-fly resizing of logical volumes as well as manipulation of physical volumes.

Mac OS X Lion Adds CoreStorage, a Volume Manager (Finally!)

CoreStorage implements a full complement of data structures but uses them in a very simplistic manner currently.

Mac OS X was majorly deficient in that it lacked a volume manager. This wouldn’t seem like a big deal to the average user, but held back the operating system in so many ways. A volume manager brings storage virtualization to an operating system, allowing storage capacity efficiently to be managed and manipulated. But all this has changed in Mac OS X 10.7 “Lion” with CoreStorage.

Which Apple Devices Support 802.11n Wi-Fi?

Apple boasts that their AirPort Extreme base station is "5x faster" but which devices can connect?

It is nice to see Apple out in front with a technology like 802.11n, considering their reluctance to support Blu-Ray and USB 3.0. Although expensive, the AirPort Extreme and 2011 MacBook Pro and iMac sport top-of-the-line specs and high performance Wi-Fi. But the lack of 5 GHz support across the board means many users will stick to the crowded 2.4 GHz spectrum, limiting performance.

What Is Paired Storage?

OWC sent me this DataDoubler, a key enabler of paired storage

Paired storage is a growing trend in the laptop computer market, with many high-end machines sporting both a SSD and hard disk drive. But it remains a game for the rich, adding many hundreds of dollars to the cost of a computer, and manually placing data is inefficient. It will be interesting to see if future operating systems bring better support for paired storage, and if it will reach into the server world.

Implications of the 2011 MacBook Air’s Unconventional SSD

Is Apple already abandoning the "blade" SSD in the MacBook Air?

As techies moan about the lack of upgrade options presented by a soldered in SSD, they miss the bigger industry picture. For too long, computers have been held back by traditional SCSI and ATA controllers. These are both a performance bottleneck and an impediment to innovation. A shift to an integrated PCI storage model makes much sense tactically and strategically for Apple, and I expect that these rumors are true. Furthermore, this move will put even more stress on Windows PC makers. Once again, Apple is outmaneuvering the competition.

Not All 802.11n Networks Are Alike

802.11n is a package of enhancements, most of which are optional

Buyers of 802.11n wireless network equipment should not assume they will see a great benefit right out of the box. Most will have to enable by hand a high-performance configuration including wide channels and 5 GHz operation. And some client devices may never reach the levels of performance expected by consumers due to hardware limitations.

How Apple iCloud Will Challenge the Storage Status Quo

Apple's iCloud is not just MobileMe 2.0!

iCloud is a key enabler of the “post-PC” experience for iOS users. It supports wireless daily backup, storage of purchased music, apps, and books, and synchronization. It also has some interesting Mac OS X features, and it’s free. But the most-compelling feature of iCloud is what it means to future applications on iDevices, the Mac, and even Windows!
