Peek-a-Boo, I See Your CPU -- Clarkwood Software's Peek-a-Boo, one of my favorite utilities under Mac OS 9 and before, has now been rewritten for Mac OS X. Peek-a-Boo is a process watcher; it displays the applications and Unix processes running on your computer, along with lots of data about them. Unix geeks and Mac OS X mavens may be tempted to dismiss Peek-a-Boo as merely a graphical front end to tools like "top" and "ps," or a partial duplicate of Apple's own utility Activity Monitor. But graphical front ends are good, and Peek-a-Boo does make it easy to do tricky things such as constructing a running graph of an application's CPU usage over time, or changing an application's priority ("renice"). It would be great if Peek-a-Boo could do even more - for example, it might show an application's open files ("lsof") or disk activity ("fs_usage"), graph memory usage over time, and so forth - and it's a pity that Peek-a-Boo is itself something of a CPU hog. But users may still find it a useful addition to their bag of Mac OS X tricks. Peek-a-Boo is $20 ($10 for previous owners), and a fully functional demo is available as a 565K download. [MAN]
Spin Through Toolbar View Options
Although many people never change their toolbars from the default settings, all standard toolbars on the Mac offer six states: icon only, text only, and icon and text, with all three coming in normal and small size. You can change them by choosing View > Customize Toolbar.
But there's a shortcut that makes it easier to check out each variant. Simply Command-click the toolbar lozenge at the upper right of a window, and the toolbar switches to the next view. Click it enough times, and you cycle back to the start.
