LulzSec Disbands, Bad Security Remains

For almost two months, an anonymous band of hackers called LulzSec made a reputation for itself by revealing internal data from organizations ranging from the Arizona police to the US Senate to the CIA. Now, the group is closing its tents. With a final release of such “valuable” data as game accounts and some internal AT&T documents, LulzSec is done.

Why the Linux netbook crashed and burned

A friend of mine, Tom Henderson, asked recently, Who killed the netbook? His well-thought out answer blames a combination of smartphones; expensive, but lightweight computers like the MacBook Air; and the rise of tablets. I think all those played a role, but I put more of the blame on Microsoft and Intel.

While I’d say netbook are dying rather than dead, I have to agree they certainly aren’t as popular as they once were. As Ranjit Atwal, research director at Gartner, recently said in a statement. “Mini-notebook [Netbook] shipments have noticeably contracted over the last several quarters.” More to the point, the vendors are agreeing with the analysts. Lenovo president and COO Rory Read recently said “Netbooks are pretty much over.”

I think netbooks—small, inexpensive notebooks–are declining because Microsoft and Intel have finally succeed in weaning original equipment manufacturers (OEM)s away from Linux and low-end—with corresponding low profit margins –hardware.

This was always Microsoft’s plan since they first were cold-cocked by the sudden explosion of customer interest in netbooks. When netbooks first came along, they almost all ran Linux. Microsoft, which was then stuck with the resource pig known as Windows Vista, simply couldn’t compete. So, reluctantly, Microsoft gave Windows XP Home a new lease on life and sold it below cost to OEMs to kill the Linux desktop on netbooks.

Five reasons Android can fail

I use Android every day both on my Droid II smartphone and my Barnes & Noble Nook Color e-reader/tablet. I like it a lot. But, I also have concerns about how it’s being developed and being presented to customers.

Before jumping into why I think Android faces trouble in the long run, let me mention one problem I don’t see as standing in Android’s way: The Oracle lawsuits Yes, Oracle claims that Google owes them billions in damages for using unlicensed Java technology in Android’s core Dalvik virtual machine.

I follow patent lawsuits and here’s what going to happen with this one. It will take years and millions of dollars in legal fees, but eventually Google will either beat Oracle’s claims or pay them hefty licensing fees. So, yes, one way or the other Google, and to a lesser extent Oracle, will spend hundreds of millions on this matter before it’s done. But, so what?

Firefox 5: New, but improved?

I’ve liked Firefox since it first showed up. But, this new Firefox 5 concerns me. Oh, it’s a fine browser. But, it’s not a major new release. At most, I’d call it Firefox 4.1, but really it’s little more than Firefox 4.02.

The Mozilla Foundation, following in the footsteps of Google’s Chrome Web browser, seems to believe that if they keep popping out new “major” releases every six weeks, they’ll convince people they’re better than the competition. That seemed like a dumb idea to me when Microsoft went from Word for Windows 2.0 to Word for Windows 6.0 back in 1993. The idea hasn’t improved any with age.

At least, in the case of Google Chrome, though, there usually have been significant updates. Chrome 12, didn’t deserve its new major release number either though. In upcoming versions of Chrome that may change. For example, We can look forward to Google building Skype-like video and Voice-over-Internet Protocol (VoIP) right into the browser. Firefox? Not so much.

The Best & Fastest Computers are Linux Computers

While Linux still has trouble getting a grip on the desktop, everywhere else Linux rules. No where is that clearer than it is in the fastest of the fast: the supercomputers.

In the latest Top 500 Supercomputer list list, which was released on June 20th, Linux accounts for 91.00 % of the top supercomputers. Linux is followed by Unix with 4.6%; and Windows with 1.2%. When it comes to super-fast computers like supercomputers or IBM Jeopardy winning Watson, Linux rules.

USB 3.0: Great technology, but hard to find

Over the last few years, the Universal Serial Bus (USB) has become the universal interface. Starting in 1995, when USB 1.0 could only transfer 12 Mbps (Megabits per second), the standard started up slowly. But when USB 2.0 came along in 2000, with its 480 Mbps, the days were numbered for PS/2, serial, parallel, and even the FireWire interface. So, why hasn’t USB 3.0, also known as SuperSpeed USB, with its 5 Gigabits per second (Gbps), become the interface of choice since its introduction in 2008? Well, there are several reasons.
