More and more people are getting into vinyl and buying turntables, but to get the best sound you need to buy a separate "phono preamp." Some entry-level turntables come with built-in preamps, and that's a great way to get started, but if you want to really bask in all-analog glory you'll need to step up to a separate phono preamp. Look around on Amazon and you'll see a vast range of models, and some are decent enough, but they're not going to sound as good as a high-end phono preamp.

Passware Inc. is a forensics security company that develops investigation software kits to reveal passwords on seized computers. Last year it released a version of its kit that allows an investigator to reveal the passwords of Apple's FileVault encryption technology, along with those for similar technologies such as TrueCrypt, PGP Disk, and BitLocker. Recently the kit has gained more features and now has the ability to snoop through a system's hibernation file for Google and Facebook account passwords.

The Passware snooping technology works by accessing a system's memory either through a port that has direct memory access (… Read more

For as long as I can remember, my iPhone 4S has had trouble connecting to certain Wi-Fi hotspots.

When I go to Panera Bread, for example, I can connect to their network on my laptop without a problem. But it requires visiting a landing page in my browser and clicking a button to agree to the terms of service.

When I try to make that same connection on my iPhone, a log-in screen immediately pops up -- but stays blank. For some reason, it fails to load that landing page, meaning I can't tap "I agree" and … Read more

Apple's Spotlight offers a quick way to find user files and resources like applications or system preferences. However, it does not locate items in the system folder or in hidden folders, though at times you might need to access them. This limitation may be especially cumbersome to deal with if you are troubleshooting a problem in OS X or helping someone do so, meaning you may need to ask them to locate a specific hidden file and remove it or modify its contents.

For some system resources you can simply navigate through the Finder; however, in its default view … Read more

Apple's AirPlay feature is a convenient technology for sending audio to various devices. If you are on the same wireless network as the device then it will be available to your Mac, iPhone, or iPad to play music via iTunes, or even be used as a general audio appliance for system sounds.

In general, AirPlay devices are hardware accessories like routers such as Apple's AirPort, or media appliances like the AppleTV. However, if you are not willing to shell out about $100 or more for a new AirPlay and you have an old Mac lying around (especially a … Read more

Tabbed browsing is one of the more useful features to make it to Web browsers. However, as with using single windows you might inadvertently close one and need to restore it. While you can create a new tab and then peruse the browser history to find a link to the content it contained, an easier option is to use the built-in tab restoration options in your browser.

To do this, there are two hotkeys to keep in mind. The first is the classic Command-Z for undoing an action, which in Safari will undo a recently closed tab in a specific … Read more

In Mountain Lion, Apple split off its reminder options from the provided calendar program and put them into a separate program similar to the Reminders app in iOS. This program lets you keep track of your projects, routines, or what have you, with to-do lists for each. As you make progress, you just mark each reminder as completed, and it drops off of its respective list.

But if, say, you inadvertently mark the wrong reminder as completed, don't worry, you can still get it back.

The Reminders program does have a Completed section that you can click to see … Read more

The OS X Terminal is a very powerful tool for configuring and using a Mac, and can be used to script and program a number of aspects of the computer's operations; however, its text-based interface can be a bit of a cryptic environment to first-timers, especially when it comes to finding out what you can use it for.

There are thousands of Terminal commands available, but when you first launch it you might not have a clue where to look for them. Of course there are basic commands like "ls" for listing directory contents or "cd&… Read more
