Using TimeMachine with a Network Device

by patrick

I am loving Leopard and have found very few snafus since installing it almost 2 months ago. One of the great features in Leopard is the automated backup software called TimeMachine.

Like many busy computer users, I am quite lax about doing backups on a regular basis. It usually takes a catastrophic loss of data to remind me that I should’ve been doing backups. A lesson learned the hard way.

But TimeMachine handles this for me now. I connect an external USB drive to my machine and, once every hour, TimeMachine does an incremental backup of my hard drive

The Axiotron Modbook was originally announced almost a year ago at MacWorld Expo 2007. At that time, this after-market hardware modification, done by a team of German and American engineers, created quite a buzz.

This mod is built primarily for mobile users, artists, or anyone who wants to draw and write directly on the screen. It uses OS X’s built in handwriting recognition software. It comes with an iSight built in, integrated CD/DVD combo drive that can be upgraded to a DVD burner, and a Global Positioning System. Yes, a GPS system, which turns this puppy into a nice, large-screen, in-car navigation system!

The top shell and interior display frame are built from magnesium alloy. The LCD panel and iSight camera are protected by replaceable screen covers made from chemically strengthened ForceGlass

More Blather from ZDNet and Dignan

by patrick

It’s pretty well known by now that ZDNet is the CNN of tech reporting. Basically, they’re one big infomercial for the highest bidder. I usually don’t bother with these things. But Dignan’s posting of December 18 is a really good example of yet another MicroSoft shill’s take on the disaster that is Windows Vista.

He uses this handy little Terrorist-Threat-Color-Coded table to show that Mac OS X users should arm themselves and hide under their beds waiting for the impending doom:

Even assuming that these numbers represent anything close to reality, one has to wonder if Dignan recognizes the very significant distinction between a vulnerability and an exploit. We should expect these kind articles to continue from establishments like ZDNet, given that MicroSoft is taking a major hit in Vista sales because it’s not only buggy, but it presents some very real security concerns.

One of the many responses to this posting summed it up quite well when he labeled the article a classic Tu Quoque:

“Tu Quoque is a very common fallacy in which one attempts to defend oneself or
another from criticism by turning the critique back against the accuser. This is a
classic Red Herring since whether the accuser is guilty of the same, or a similar,
wrong is irrelevant to the truth of the original charge. However, as a diversionary
tactic, Tu Quoque can be very effective, since the accuser is put on the defensive, and
frequently feels compelled to defend against the accusation.”

Carry on…

Move To Leopard Could Prove Troublesome

by patrick

As the debut of Apple’s latest operating system nears, the rumblings about incompatibilities and problems increases. Although the new features are impressive, the problems and barriers to easy upgrade for exiting Tiger users is making quick adoption more difficult.

It’s not clear to me that this new OS will make my life easier/better in the educational environment I manage. For the first time, I will be testing this OS on a non-essential machine, and watching carefully the feedback from folks on several online forums. My move to Leopard will be slow and careful, despite my enthusiasm for new technology.
