Build your own open-source cloud with ownCloud 4

Big businesses use cloud services. You and I use cloud storage services like DropBox, Google Drive, and Amazon Cloud Drive every day. But, with each you have to trust your data on other people’s systems. With ownCloud, an open source file sync and share project, which began as a KDE project, you can keep your data on your servers and decide what other public cloud services you want to integrate into your personal cloud.

OwnCloud is primarily as an Infrastructure as a Service (IaaS) cloud service. With it you can store your files, folders, contacts, photo galleries, calendars and more on a server of your choosing. You can then access that storage from your mobile device, your desktop, or a Web browser. You can also sync your date with local devices and share your data either with the world at large or specific approved users.

With the new, just released version, you also now get file versioning, which allows you to “rollback” to previous versions; file-level encryption, Web-based drag and drop file management, and a built-in Open Document Format (ODF) preview.

Sudo broken, sudo fixed

Linux and Mac OS X users and system administrators, and long before them, Unix users and sysadmins, have used sudo as an essential computer management tool. With it, users are given the power to make essential, but sometimes dangerous, changes to their systems. Recently a fundamental security bug in sudo was discovered, In some network this security hole could allow a cracker unlimited control of Linux, Mac OS X, and Unix systems. Fortunately, the bug has now been fixed.

I, robot owner

We’re used to robots — in their place. Think of a car factory; the image that comes to mind is probably not the assembly line of yore, but instead pivoting robot arms doing mind-numbingly repetitive tasks with great precision. But other than vacuum cleaners and the odd robotic pet, robots are mostly absent from our daily lives. Are we ready for that to change, with robots sharing our highways and homes? We’d better be, because they’re coming.

On May 7, Nevada became the first state to issue a license for self-driven cars. These Google-developed cars are also known as autonomous vehicles, but make no mistake: They are robots.

Chrome beats Internet Explorer in global Web browser race

The last time Internet Explorer (IE) wasn’t the top Web browser in the world, late 1998, Bill Clinton was president; France was the World Cup champion; Netscape was IE’s top rival; and, oh yes, Google was founded. One anti-monopoly lawsuit, which was largely based on Microsoft’s illegal tactics against Netscape, and not quite fourteen years later, IE has finally been knocked off as king of the browser mountain by Google’s Chrome Web browser.

According to StatCounter, Chrome passed Internet Explorer during the week of May 13th. StatCounter’s stats are based on a sample of 15 billion page views in the company’s network and they show that Chrome is continuing to gradually pull away from IE.

Today, Chrome has taken first place with 32.76 percent share, while IE dipped to 31.94 percent. Chrome has been slowly moving up on IE for years now. The first time Chrome moved past IE, for even a day, only came on March 18th.

Waiting on the Real Apple TV

You may have noticed that when I talk about TV over the Internet, I haven’t been talking about Google TV or the like. Instead, I’ve been focusing on “media extenders” like the Apple TV, Roku, and the various Internet-equipped Blu-Ray DVD players. The main reason is the elephant in the room: “When will Apple announce an iTunes-empowered TV, aka a “real” Apple TV. We still don’t know when, of indeed if, Apple will make its move, but the possibilty, probablity, has everyone waiting to see what happens next in Internet TV.

Oh sure, the Leichtman Research Group claims that Americans report that 38% of homes already have an Internet connected television (PDF Link), but only 4% of them say that their Internet TVs are actually hooked up. Yeah, right.

I think most people still don’t have a clue about to get the Internet and their televisions in sync. Today, people who watch TV via the Internet are like me: Electronics fans and network savvy geeks. The current generation of Internet TVs is part of the reason why that’s so. None of them are all that user friendly.

Five ways to avoid Windows 8

Some people are still sure Windows 8 is going to be the cat’s meow. I’m sure Windows 8 and its Metro interface will be more like a cat’s yowl of pain. The more I look at Metro, the more I’m sure that Microsoft’s new desktop will flop as badly as the Facebook IPO.

It’s not just me. Business analysts, who could care less about technology but care a lot about what customers think, are saying things like “Windows 8 will prove to be a disappointment.”

Windows users who were already unhappy about having to learn Metro, which doesn’t work or look a thing like Vista and Windows 7’s Aero interface never mind XP’s familiar appearance, are finding out there’s more trouble ahead for them. Windows 8 will cost more at launch to upgrade to from Windows 7. DVD playback and media-center functionality will now be an extra-price option.

Oh as for Metro-friendly applications, here’s what Matthew Baxter-Reynolds, an independent software development consultant, speaker, author, and trainer and all around Windows guru who’s writing the book “Programming Windows 8 Apps with C#” had to say: “does Metro actually work? In my opinion: No.”

I don’t care if your most prized possession is an autographed copy of Bill Gates’ The Road Ahead, you have got to be wary of moving to Windows 8. So what can you do to avoid, or at least delay, the day you have to start using it?
