I wasn't listing 'features'. I was listing reasons the published growth rates might not necessarily be indicative of future performance.

In other words, Apple could end the exclusivity deal and immediately sell a bunch of iPhones to non AT&T users.

Let's take that Android growth rate.

Now factor in that it's almost exclusively among people who have contracts with carriers that don't offer iPhones.
Now factor in that it's for the US only.
Now factor in that it's doesn't mention that Apple sells other devices (iPods, iPads) that are part of the same 'ecosystem' as the iPhone.

I think you're declaring this competition over a little prematurely.

Real-World Benchmarks of Ext4 249

Ashmash writes "Phoronix has put out a fresh series of benchmarks that show the real world performance of the Ext4 file-system. They ran 19 tests on Fedora 10 with changing out their primary partition to test Ext3, Ext4, Xfs, and ReiserFS. The Linux 2.6.27 kernel was used with the latest file-system support. In the disk benchmarks like Bonnie++ Ext4 was a clear winner but with the real world tests the results were much tighter and Xfs also possessed many wins. They conclude though that Ext4 is a nice upgrade over Ext3 due to the new features and just not improved performance in a few areas, but its lifespan may be short with btrfs coming soon."

The Myth of Upgrade Inevitability Is Dead 597

Several readers pointed out a ComputerWorld UK blog piece on the expanding ripples of the Vista fiasco. Glyn Moody quotes an earlier Inquirer piece about Vista, which he notes "has been memorably described as DRM masquerading as an operating system": "Studies carried out by both Gartner and IDC have found that because older software is often incompatible with Vista, many consumers are opting for used computers with XP installed as a default, rather than buying an expensive new PC with Vista and downgrading. Big business, which typically thinks nothing about splashing out for newer, more up-to-date PCs, is also having trouble with Vista, with even firms like Intel noting XP would remain the dominant OS within the company for the foreseeable future." Moody continues: "What's really important about this is not so much that Vista is manifestly such a dog, but that the myth of upgrade inevitability has been destroyed. Companies have realized that they do have a choice — that they can simply say 'no.' From there, it's but a small step to realizing that they can also walk away from Windows completely, provided the alternatives offer sufficient data compatibility to make that move realistic."

Tips For Taking Your Laptop Into and Out of the US? 940

casualsax3 writes "I'm going to be taking a week long round trip from NYC to Puerto Vallarta Mexico sometime next month, and I was planning on taking my laptop with me. I'll probably want to rip a few movies and albums to the drive in order to keep busy on the flight. More important though, is that I'm also going to be taking pictures while I'm there, and storing them on the laptop. With everything in the news, I'm concerned that I'll have to show someone around the internals of my laptop coming back into the US. The pictures are potentially what upsets me the most, as I feel it's an incredible violation of my privacy. Do I actually need to worry about this? If so, should I go about hiding everything? I've heard good things about Truecrypt. Is it worth looking into or am I being overly paranoid?"

From what I understood (correct me if I'm wrong!), the movie 'cars' was actually done using a ray tracer, which for pixar was a first.

You're wrong. Renderman has options for ray tracing, it's still using it's rasterization for most stuff. Doing everything with raytracing would be incredibly inefficient, and wouldn't look any better.

Particle Swarm Optimization for Picture Analysis 90

Roland Piquepaille writes "Particle swarm optimization (PSO) is a computer algorithm based on a mathematical model of the social interactions of swarms which was first described in 1995. Now, researchers in the UK and Jordan have carried this swarm approach to photography to 'intelligently boost contrast and detail in an image without distorting the underlying features.' This looks like a clever concept even if I haven't seen any results. The researchers have developed an iterative process where a swarm of images are created by a computer. These images are 'graded relative to each other, the fittest end up at the front of the swarm until a single individual that is the most effectively enhanced.'"

Submission + - Attacking Multicore CPUs. (theregister.co.uk)

Ant writes: "The Register reports that the world of current multi-core central processing units (CPUs) just entered is facing a serious threat. A security researcher at Cambridge disclosed a new class of vulnerabilities that takes advantage of concurrency to bypass security protections such as antivirus software The attack is based on the assumption that the software that interacts with the kernel can be used without interference. The researcher, Robert Watson, showed that a careful written exploit can attack in the little timeframe when this happens, and literally change the "words" that they are exchanging. Even if some of these dark aspects of concurrency were already known, Watson proved that real attacks can be developed, and showed that developers have to fix their code. Fast...
