Firefox developer Vladimir Vukićević:
All these WK* methods are undocumented, and they appear in binary blobs shipped along with the WebKit source (see the WebKitLibraries directory). There are now over 100 private “OS-secrets-only-WebKit-knows” in the library, many of which are referred to in a mostly comment-free header file. Reading the WebKit code is pretty interesting; there are all sorts of potentially useful Cocoa internals bits you can pick up, more easily on the Objective C side (e.g. search for “AppKitSecretsIKnow” in the code), but also in other areas as a pile of these WK* methods used in quite a few places.
David Hyatt writes in the comments:
The programmatic disabling of coalesced updates should not be public API. It’s actually a very dangerous thing to do. We aren’t really happy with that code in WebKit, but we had to do it to avoid performance regressions in apps that embedded WebKit. Technically it’s wrong though, since we turn off the coalesced updates for any app that uses WebKit! This includes drawing they do that doesn’t even use WebKit.

Any change in the Air’s design immediately snowballs into a larger, heavier, hotter and (probably) less solid-feeling machine. Jobs obviously thought it was worthwhile to concentrate on those aspects, and it’s rather shortsighted to conclude that “Apple is not paying much attention to … workmanship.”

Guy English, on how Airfoil shows your Mac’s desktop, superimposed onto a picture of your Mac, as the icon to identify it on Apple TV. I wonder why Apple’s icons for the different Mac models use the old blue desktop instead of the black and purple Leopard one.
MGTwitterEngine is a Objective-C class which lets you integrate Twitter support into your Cocoa application, by making use of the Twitter API. The entire API is covered, and appropriate data is returned as simple native Cocoa objects (NSArrays, NSDictionarys, NSStrings, NSDates and so on), for very easy integration into your own application. MGTwitterEngine is designed for Leopard, but should be just fine on Tiger too.

Ed Felten (via Drew Thaler):
Our results show that an attacker can cut power to the computer, then power it back up and boot a malicious operating system (from, say, a thumb drive) that copies the contents of memory. Having done that, the attacker can search through the captured memory contents, find any crypto keys that might be there, and use them to start decrypting hard disk contents.
Seems like the OS should secure-erase the RAM when the user isn’t around.

Ideally, it would be better—both in terms of consistency and usability—if Apple had changed this behavior in the Carbon Data Browser, too. The overwhelming majority of Mac users have no idea what Cocoa and Carbon are, so the different behavior in the Finder and iTunes is, to them, seemingly arbitrary. But if there’s one single thing I hoped to see Apple do regarding this issue in Leopard, it’s exactly what they did: change it in NSTableView.

The only possible conclusion is this. It’s very helpful of Microsoft to release the file formats for Microsoft and Office, but it’s not really going to make it any easier to import or save to the Office file formats.

Gus Mueller has released a new beta of his elegant Acorn image editor that includes my most-wanted new features: a Levels window and a Web export window that lets you preview the image quality and file size.

It is tough to imagine how anyone could run a parts and supplies department without having done something similar, once they had made the observation that not all parts fit all models. But how to use this as prior art in a court case? You’d want to find a publication explaining this process in detail, but why would an employer do that since one would expect to be able to hire a temp worker and walk him or her through the process in 10 minutes. You can’t find an academic publication on how to answer a telephone, open a filing cabinet, and put some documents into a fax machine. Cookbooks don’t say “make sure to set the table with plates before serving this food; you don’t want to place the steak directly on the table or tablecloth.” Paradoxically, the more trivial the process the harder it will be to find prior art in a publication.

SuperDuper 2.5 includes full Leopard compatibility and can store its backups on the same volume as a Time Machine backup.
There is no FireWire on the MacBook Air, so Apple had to redo Migration Assistant to get around that limitation. “Great, Apple finally fixed Migration Assistant to work over USB 2.0!”
Bzzt! Thank you for playing. That would be too easy, my Apple-faithful friends. Instead, Air users who want to use Migration Assistant must do so either over WiFi (the default setting) or a USB Ethernet adapter.
…Don’t waste even a single minute of your time on WiFi. If you really must transfer your settings, buy a $29 Ethernet adapter.
