The Case of the Missing Letters: Another Obnoxious Bug in Dragon Dictate

Sriously? I hav to disabl spll corrction to kp Dragon Dictat from dropping lttrs all th tim?

Any time OS X corrects your spelling or (more likely) inserts appropriate accent marks, Dictate loses its mind and can no longer correctly enter some random letter. There are two ways to fix this problem (apart from just restarting Dictate all the time).

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.

How Does Dropbox Store Data?

On my Mac, Dropbox clearly uses a 4 MB "chunk" size for deduplication

Dropbox recently clarified (via their blog and privacy policy) that they “de-duplicate” user files. This has been known for quite a while, and is obvious to anyone who’s had a large file “upload” instantly. But how exactly does Dropbox store files? Are they really de-duplicated or just single-instanced? I set out to discover the answer.

Mac Users, Secure Your Stuff in Dropbox

Disk Utility in Mac OS X can create an encrypted "SparseBundle" compatible with Dropbox

Encryption is an important tool for individuals regardless of what they’re storing. Given the recent security failings of Dropbox, I highly recommend using methods like this to secure your important data before using the service!

Three Key Storage Features Missing in Mac OS X “Lion”

Mac OS X 10.7 "Lion" lacks many of the storage features we've long hoped for, including ZFS, iSCSI, and USB 3.0

Apple is not in enterprise storage company to be sure, and news from WWDC dashes any hopes we had for ZFS and iSCSI support. USB 3.0 seems a foregone conclusion, but Apple seems intent on ignoring it as long as possible. Although I welcome the new storage features included in Lion, it is disappointing that these were left out.

Key Storage Features in Mac OS X 10.7 “Lion”

Mac OS X 10.7 "Lion" lacks many of the storage features we've long hoped for, including ZFS, iSCSI, and USB 3.0

Apple’s not an enterprise company or a storage company, but Apple does have enterprise storage features in their operating systems. And Mac OS X 10.7 “Lion” is a great case in point. From Versions to Time Machine Local Snapshots to AirDrop, Lion brings some storage love, and NFS, SMB, and Xsan are there, too. Let’s look at what’s new and key in terms of storage in the latest version of Mac OS X.

Snooping on AirDrop in Apple’s Mac OS X 10.7 “Lion”

AirDrop enables direct file sharing over Wi-Fi

Apple has aggressively moved to eliminate “superfluous” peripherals and connections, wiping out the floppy and now selling a number of machines without optical drives. AirDrop continues this progression, attacking the prime use case for USB flash drives.

Dragon Dictate for Mac: Utterly Frustrating

Dragon Dictate might be the best dictation option for Mac users, but it's not very good at that

For the last few months, I’ve been experimenting with dictation software on the Mac. Previously, I had used the built-in dictation software in Windows Vista and Windows 7, but it was annoying to launch a virtual machine every time I wanted to dictate something. On the Mac and purchase an (expensive) copy of Dragon Dictate for Mac. So far, my experience has been less than positive.

Boxcar Growl Plugin Not Working?

Boxcar Growl settings

The Boxcar plugin is a “display” not an “application”, so it shows up under the “Display Options” tab, not the “Applications” tab in Growl on Mac OS X. The plugin installation automatically opens the wrong tab!
