PowerBook heat: a follow-up
Regarding Monday's mention of how hot the PowerBook G4 seemed to feel to Expo attendees picking one up, reader reaction was split. Some noted that the new PowerBooks were displayed on a case that was shining a light on the bottom of the case; this is what accounted for the excessive heat. The other view pointed to the conductivity of Titanium, which may even serve as a heatsink for the processor, as the cause.
No more cross-over cables needed!
Chris Stone writes: "I heard from Apple engineers at Macworld Expo that the PowerBook G4's Ethernet port will sense if there's another machine at the end of a regular network cable (and not a hub, etc.) and use circuitry to crossover the necessary pins to allow computer to computer connection, eliminating the need for a special crossover cable to do this." The PowerBook G4 Developer Note confirms this, stating:
"The Ethernet port on the PowerBook G4 computer supports Auto-MDIX: It switches between MDI (Medium Dependent Interface) and MDI-X operation automatically, so it can be connected to another device by either a straight-through cable or a cross-over cable."
Another Multiple Users security leak (source)
Todd Kirby reports a security hole in Mac OS 9's Multiple Users (as also reported on BugTraq):
Mac OS 9.0.4 comes with a 'Multiple Users' Control Panel that allows an administrator (called 'Owner') to create user accounts (called 'Normal' users) with limited access to the computer. The problem is that the Owner password can be removed by a Normal user by moving the 'Users & Groups Data File and logging back in using the Owner account, giving full access to the machine. Exploit: Log in as a Normal user. Find the file called 'Users & Groups Data File' in the Preferences Folder and move it to another location. Log out and back in using the Owner account. Result: No password is required to log in as the Owner user. User now has full access to the computer, including the ability to make changes in the 'Multiple Users' control panel. The previously moved 'Users & Groups Data File' can be moved back into the Preferences folder to restore the original Owner password making detection difficult.
Another Multiple Users security leak? (source)
Dave Jackman found yet another security weakness in Multiple Users. He writes that: "Under Limited or Panels, immediately after a user has exited and returned to the Welcome screen, if they then click on Owner, click on Change Password, they can then enter the user's password as the owner's, change the password to the user's one and then re-enter to gain full access to the computer as though they were the owner!"

A caution regarding checking for viruses in compressed files [01/04/01]
Most anti-virus utilities today have an option to check for viruses in compressed files (such as StuffIt archives) before you expand them. If you rely on this option, be careful. If the compressed file contains an Installer that itself installs another Installer, and the secondary Installer has an infection, anti-virus utilities will not detect it. Your best bet in such cases is to directly check for viruses in these files immediately after decompressing the archive. [click here for more info]
Getting your iBook to stay asleep when you close the lid [12/21/00]
Does your iBook mistakenly wake-from-sleep when you close your iBook? In most cases, the cause is that the keyboard is slightly raised, so that a key gets depressed by the lid, causing the iBook to wake up. The cure is simple: remove the keyboard, flex it a few times to straighten it, and then replace it. [click here for more info]
Fix the Epson software and Remote Access crash conflict [12/14/00]
One of the most persistent and frustrating problems experienced by users of Epson printer software is that using Apple's Remote Access control panel led to system crashes if the Epson software was installed. An update to the Epson driver software finally fixes this. [click here for more info]
TechTool Pro 3 users: reclaim drive space occupied by defunct invisible files [12/07/00]
TechTool Pro 2 users who upgrade to TechTool Pro 3 may be able to reclaim as much as 100MB or more of disk space. TechTool Pro 3 installs a new set of invisible "•TP3" files and folders, including a new TrashCache folder. In at least some cases, the older TechTool Pro 2 files/folders are not deleted. This means that, for those that previously used TechTool Pro 2, any existing invisible files in the "•TP2" TrashCache will become inaccessible. It also means that these files will never be automatically deleted. The solution is to use a utility (e.g., Sherlock; File Buddy) that can display and delete these files - and then delete them.
