Installing DiskDoubler is easy. Simply double-click on Salient's installer application and it automatically installs the DiskDoubler files, including the application, the extension, and the help file

Installing SuperDisk! is equally as easy as installing DiskDoubler. If you're running System 6.0.x, simply drag the SuperDisk! Control Panel into your System Folder

Although DiskDoubler and SuperDisk! both serve the same function, how they approach the task differs. When you compress a DiskDoubler file, you'll know it's compressed right away - the icon for the document or application that you just compressed turns into a DiskDoubler icon

Apple's becoming kinder and gentler in its old age. First Apple admitted that the dirty ROMs were a problem and licensed MODE32 from Connectix to give away for free

The operating systems wars have become harder to keep track of than who hates whom in the Middle East and Central America combined. On the low end, Novell bought Digital Research and its version of DOS, called DR DOS (which was just updated)

Small software companies suffer as much at the hands of big business as do small publishing companies. In all likelihood, you haven't seen any products by Working Software around recently

Last weekend, after punishing my body with a fast 5K road race that ended with a nasty uphill stretch, Tonya and I shuffled slowly around the aisles at the Boeing Computer Users Group Fair in the Seattle Center Expo Hall

The latest in corporate sleaze comes from Que Corporation, which has just published a Macintosh book called The Little Mac Book by Neil Salkind. Hmm, that sounds familiar

Earl Williams recently informed me about a catch to the great deal that International Business Software offered with DataClub, WriteNow, Panorama, and MacCalc

If you're the sort who pays attention to corporate mergers, you'll remember that Novell was in the process of buying Digital Research, Inc. (DRI) earlier in the summer

Some people would prefer that title to be "Apple/IBM: It's Oh-fish-al," since they think they detect a tell-tale smell. However, the Apple/IBM deal appears to be real and was consummated last week in the press releases, where all good industry relationships eventually end up
