One of the most annoying things about Apple’s Bluetooth implementation in iOS is that turning it on or off is a four-step process involving digging deep into Settings. Considering the battery drain associated with just leaving Bluetooth on and the wide variety of devices you can connect via Bluetooth to your device, it’s a constant irritation for many.

Jailbreak utilities like SBSettings make turning bluetooth on/off on the fly a fairly simple proposition, but unfortunately, Apple hasn’t borrowed inspiration from any of them when it comes to baking better Bluetooth toggling into iOS. A new $0.99 app on the App Store, though, makes it much easier to toggle Bluetooth on the fly on your device even without a jailbreak. Launch the app once to toggle Bluetooth on, launch again to toggle off. Simple.

Gemini is a Mac app that does one thing: Find duplicate files on your Mac. You just point it at a directory (your home folder is a good place to start) and sic it on your files. After a few moments it gives a list of anything that is doubled-up on your machine, and then the fun begins.

Playing music through iTunes is something we do every day. It’s great to be told what track is playing when it starts, but not everyone wants to run a system notification app like Growl. If you still want to be see what the current iTunes track is, check out today’s tip.

I was a big fan of the Alupen when it launched — so much so that I went out and bought my own. It was chunky, looked like a metal pencil and felt pretty good in my big hands. Then came the Wacom Bamboo stylus and our love affair was over.

Now, though, the newer skinnier, cleverer Alupen Pro has got me two-timing the svelte Bamboo. Why? Because it has a biro built in.

Today mark’s the 35th anniversary of the iconic Apple IIe, the first PC that can really be said to have achieved true mainstream success, but between the Apple IIe and the Mac, there was another computer: the venerable Apple Lisa, which Steve Jobs named after his daughter Lisa Brennan-Jobs.

The Lisa was a first for Apple in many ways: the first Apple computer to have a GUI, and the first Apple computer to ship with a mouse… both ideas that were borrowed by Steve Jobs from his historic visit to Xerox’s PARC labs. Unfortunately, due to both its price ($10,000 new) and the repeated delays, the Lisa never took off, and was in fact almost immediately replaced by the less expensive Lisa 2.

If you’ve got a 25K bill deep wad of Washingtons, though, you can now pick up a rare Lisa 1 computer system in original box on eBay, courtesy of the same seller who put that $100K 128K Mac prototype on sale earlier this week.

[UPDATE: See the end of the post for a possible solution, which works for some people.]

Many iPad 3 users are experiencing a bug which kills their 3G connection every time they connect to a Wi-Fi network. The cellular connection looks normal, with the carrier name, the 3G logo and reception bars, but when you try to do anything that requires a connection, it either times out or throws the error messages “Could not activate cellular data network.”

I am having the exact same problem, and here’s what’s happening.

If, like many people, you find Mondays just too much to cope with, you might want to avoid today’s app. It’s not the sort of thing that’s going to make your Monday feel any better, and in some cases it will just fry your brain until next Monday. Which would be a shame, because you’d miss out on a whole weekend.

Be forewarned, then: The Fourth Dimension is an app which will mess with your head. Deliberately. Even though the aim is education and expansion of knowledge, it will still mess with your head. You will emerge from the experience only fractionally the wiser, and quite a lot more confused than you were at the beginning. Don’t worry, this is perfectly normal.

Thursby last week released ADmitMac PKI 4. The release is a specialized version of the company’s ADMit Mac software that focuses two factor authentication. The solution is largely aimed at government customers and regulated industries like healthcare where data security is paramount.

Thursby’s ADMitMac is an Active Directory integration solution that offers several features beyond the built-in Active Directory support that Apple provides in OS X. It offers Mac management capabilities, improved browsing of Windows network resources including Microsoft’s distribute file system, and a number of other administrative tools.

Many of us manage Mac labs, whether for a school or a community agency, that require users to acknowledge an Acceptable Use policy, or agree to terms about using the computer. Wouldn’t it be great if there was some way to get this to show up on the Mac before a user logged in? Turns out, there is.

Exactly one month after the device made its debut in the U.S. on March 16, the new iPad will arrive in South Korea and 11 additional countries this week.
