How to track when users log on in OS X

If you have a system that you allow other people to use, you may at times want to be able to see when others have logged into your system. This may be particularly true with systems you use as a server, a workstation at a school, or even a family computer that may have multiple accounts on it. Though the system has tools like the Console or Activity Monitor, which can show information about users on the system, using these to track when they logged in can be a bit cumbersome.

To view this information specifically, the terminal has a … Read more

Microsoft's new home page goes 'Metro'

Microsoft is testing a new version of its home page that completely changes its lineup of products and services depending on whether you're there for "work" or "home."

While the idea of a custom-tailored site is nothing revolutionary, Microsoft has managed to go about it in a rather creative way, making use of a Web-based variant of its "Metro" UI that has the page slide from side to side instead of reloading, or having users scroll downward. The same look and feel as can be found in Windows Phone 7 and the recently refreshed Surface computer, … Read more

Libraries in OS X

As its name suggests, a library in OS X is a central location for a number of shared resources that the system and applications use, which can include alert sounds, desktop pictures, fonts, Internet plug-ins, and other similar items. Sometimes, as in the case with fonts, these are accessed by multiple applications, but other times individual applications may set up their own resource folders in the library. In addition to static resources, libraries are also used to store temporary items such as caches, preferences, and cookies.

There are four main libraries in OS X that serve similar but different purposes, … Read more

Futuristic touch screen puts the desk in desktop

editor's notebook The future just keeps getting closer and closer these days. Not only do we have iPhones with FaceTime--which, when combined with the iPod Nano (as I'm sure they will be before too long) will come pretty close to creating a mass-market version of Dick Tracy's two-way wrist TV--we've also got robot cars and, ahem, robot journalists (which I'm trying to keep at bay by way of this terribly sophisticated and never-ending sentence--apparently the roboscribes have trouble with such Proustian gymnastics: Quick! They're coming for our jobs! Hand me another semicolon and an … Read more

Thin client computing grows up

I've been following the evolution of client-side computing off and on for over 20 years. Remember ASCII terminals? Green screens? Beehives? X terminals? If you do, they're most likely dimming memories.

The history of client side computing is filled with efforts to shift the balance of power between the server (ne host) and the client device. Which side is responsible for what, and how the sides communicate with each other, determine the cost, control, security, flexibility, and richness of the result. Some years it's "do everything meaningful on the server." Others, "do most work … Read more

Browsing the Web with a wave of the hand

Imagine if you could pray to your computer to stop the beach ball of doom from spinning, the blue screen of death from staring you in the face.

Perhaps someday sooner than we think, such a simple, palm-to-palm gesture might actually serve to trigger a series of operations that would lead to an appropriate fix.

As reported by Engadget and Read, Write, Web, a group of students at MIT's Media Lab has hacked around with Microsoft's Kinect gaming technology, Google's Chrome browser, and Javascript to allow Web surfers to manipulate a browser with nothing more than gestures. … Read more

Defrag GUI

For about as long as there's been a Windows, developers have been targeting the disk defragmentation utility for improvement. JkDefrag is a free, open-source defragmentation utility; JkDefrag GUI is a graphical user interface version that makes the powerful tool as easy to use as the built-in Windows feature and its many competitors.

JkDefrag GUI opens with a compact properties dialog that serves as a primary control interface. We selected what Actions we wanted JkDefrag to perform and which of our drives to check from drop-down menus and started the program. A compact view opened, displaying the program's progress … Read more

Android gets a multi-browser advantage

The browser wars have extended to mobile devices, and that's good news for consumers.

Last week, Mozilla released a second Firefox beta for Android. Yesterday, Opera released its first Opera Mobile beta for Android. Neither is ready for prime time, much less used on more than a tiny fraction of phones, but already I see them as a step forward.

Why? Because now there's an important new front in the browser wars.

And while that means more stress for browser makers and more testing for Web developers, it holds the potential to dramatically improve browsing for the rest … Read more

Facebook app developers sold user info

Facebook has revealed that a data broker has been buying identifying Facebook user information from app developers, and as a result the social-networking powerhouse has placed some developers on a six-month suspension.

The announcement, which Facebook made Friday afternoon on its developer blog, comes on the heels of the revelation that many popular Facebook apps were transmitting user IDs--which can be used to look up a users' names and, in some cases, the names of the app user's friends--to at least 25 advertising and data firms.

According to Facebook's developer blog:

As we examined the circumstances of … Read more
