Qt usually takes the boring memory allocation and deallocation from you, either through its implicitly shared containers, or with QObject's parent child relationship model. But every once in a while, we need to allocate something on the heap, and then the stress starts - where do we delete it, and how do we make sure to not leak the memory? To fix this problem, QScopedPointer was born. It will delete the object it is pointing to automatically when it goes out of scope.

A reader asks: Why is Linux still not as user friendly as the two other main OSes with all the people developing for Linux? Is it because it is mainly developed by geeks? My initial feeling when reading this question was that it was kind of a throwaway, kind of a slam in disguise as a genuine question. But the more I thought about it, the more intrigued I felt. There truly are a large amount of resources being dedicated to the development of Linux and its operating system halo (DEs, drivers, apps, etc). Some of these resources are from large companies (IBM, Red Hat, Novell). Why isn't Linux more user-friendly? Is this an inherent limitation with open source software?

Like any true geek who's addicted to online presence, a VoIP SIP, Twitter, and a multi-protocol IM application are the first kinds of apps I am trying to locate when jumping smartphone platforms. The iPhone is currently my platform of choice, and the AppStore has its share of such communication applications. So I decided to give a whirl to Acrobits' Softphone, set it up with Gizmo5 and Google Voice, and use it to call my family in Greece or more rarely, my husband at work. Update: New version is out, fixing most of the things mentioned in the review below, and implementing PUSH.

I've often wondered why computers - be it laptops or desktop - are so relatively monolithic. Wouldn't it make much more sense to have a whole cluster of very tiny individual computers, all with their own tiny processor, RAM, data storage, and serial ports, which power up when needed and are easily replaced when broken? Well, Liquidware thought so too, and came up with the Illuminato X Machina.

Apple has posted the responses to the FCC's questions on its website. "We are pleased to respond to the Wireless Telecommunications Bureau's inquiry dated July 31, 2009, requesting information regarding Apple's App Store and its application approval process." AT&T made a short statement too. Update: And Google too.

Apple and AT&T Friday are expected to tell the Federal Communications Commission why Google's free voice application, called Google Voice, is banned from the Apple iPhone. Google is also filing comments. But Google may soon find itself on the hot seat as well, telecom and public policy analysts say. Why: Consumers who use Android, the Google-developed operating system for wireless devices, can't use Skype, a leading Voice over Internet Protocol service. A pioneer in free Internet calling, Skype allows you to talk as long as you want without draining cellphone minutes. Android users get Skype Lite, a watered-down version of the original that routes calls over traditional phone networks — not the Internet. As a result, long-distance calls are still cheap or free, but cellphone minutes are gobbled up every time a Skype Lite call is made.
