Four Reasons Firefox 4 can make a go of it–And one reason why it can’t.

In 2004, Internet Explorer (IE) 6 was already a security nightmare but since Microsoft has stomped all over Netscape and alternative browsers like Mozilla, now SeaMonkey, and Opera had little traction, Windows users pretty much stayed with IE… until Firefox appeared. It was a breath of fresh air. IE users concerned with security and open-source fans quickly flocked to the new Web browser, and over time others followed. But, in the last few years, Firefox lost some of its luster. Can Firefox 4 restore it?

Now that Firefox 4 has been released a day early, albeit after months of delays, I asked myself if Firefox 4 really was, not just better than the Firefox 3.6.x series, but it’s more serious competitors: IE9 and Chrome 10.

To see how it would do I’ve been running the Firefox 4 betas, release candidates, and just now the final, on Windows 7 SP1, Windows XP SP3, and the Mint 10 Linux distribution. For XP and Windows 7, I used a Gateway SX2802-07 desktop. This PC uses a 2.6GHZ Intel Pentium Dual-Core E5300 processor and has 6GBs of RAM and a 640GB hard-drive. For my Linux Firefox box, I used a Dell Inspiron 530S powered by a 2.2-GHz Intel Pentium E2200 dual-core processor with an 800-MHz front-side bus. This box has 4GBs of RAM, a 500GB drive. This is what I found.

AT&T & T-Mobile: Already Married in Technology

The news that AT&T was going to buy T-Mobile for a cool $39 billion surprised, and even shocked, a lot of people. I don’t know why. AT&T and T-Mobile have been working together technically and operationally for years.

As Glenn Fleishman, wireless networking expert, points out in his latest blog, “One of the dirtiest barely secrets of the modern mobile cell world is that AT&T doesn’t really have national 2G coverage, much less 3G. AT&T leans on T-Mobile for a large number of areas it never spent to cover. This stems from an agreement years ago when AT&T Wireless consolidated on GSM service, and T-Mobile was building out its initial GSM service. In 2004, the companies dissolved a cooperative agreement (when Cingular bought what was then AT&T Wireless), but roaming never disappeared.”

Oh my God! Porn is officially on the Internet!

Can you believe it! There’s porn on the Internet!

Cue Avenue Q’s The Internet is for Porn.

What really happened was that after a decade-long fight, Internet Corporation for Assigned Names and Numbers (ICANN), at the close of its 40th public meeting in San Francisco finally approved the .XXX top-level domain (TLD http://www.icmregistry.com/news/welcomeapproval.php). According to a PC Magazine report, Peter Dengate Thrush, a New Zealand lawyer and chairman of ICANN, announced today, March 18th, that ICANN had finally approved this red-light district TLD.

If you think this was done with the approval of the adult entertainment industry, you’d think wrong. They hate it. According to a press release by the Free Speech Coalition, an adult industry trade association, FSC Executive Director Diane Duke said, “”Over the past seven years, we have tried to communicate the adult industry’s opposition to .XXX at every opportunity, using every means and forum available. We have participated in public comment periods, letter writing, conversations with stakeholders, and testimony at ICANN’s public meetings. All three of the world’s only existing adult-trade-associations have issued statements in opposition to .XXX.”

Does Google’s Android violate Linux’s Copyright?

Does Google’s Android smartphone and tablet operating system violate Oracle’s patents? Who knows. I’m no software patent lawyer, but I cover intellectual property (IP) lawsuits far too often and I expect it will be years before the courts decide, or, as is more likely Google and Oracle will come to a licensing agreement. But, now one attorney is claiming a much more clear-cut IP law violation: Android violates Linux’s copyrights.

Edward J. Naughton, an IP attorney and partner at the international law firm Brown Rudnick, building on the work of Ray Nimmer, a copyright law professor at the University of Houston Law Center, claimed that when Google built Android around Linux and its GNU General Public License version 2 (GPLv2), that “a key component of Android–the Bionic Library [which] is used by all application developers who need to access the core functions of the Linux operating system. Google essentially copied hundreds of files of Linux code that were never meant to be used as is by application developers, ‘cleaned’ those files using a non-standard and questionable technical process, and then declared that the code was no longer subject to the GPLv2, so that developers could use it without becoming subject to copyleft effect that would normally apply to GPLv2-licensed code taken from the Linux kernel.”

Red Hat turns on Oracle and other Red Hat Linux clone-makers

Red Hat has decided it’s no going to be Mr. Nice Linux anymore for Red Hat Enterprise Linux (RHEL) clone makers such as Oracle and CentOS . Sure, in open-source, you share the code. That’s rule one. But, that doesn’t mean you need to make it easy for your rivals.

What Red Hat has done, for the last several months, is release its version of the Linux kernel with all its own patches incorporated into the RHEL code. Before that, pre-RHEL6, which was released in November 2010, Red Hat released the vanilla Linux code with its improvements and fixes in separate patches. This method made it very easy for an Oracle or another Linux distributor to see exactly what Red Had had done and thus made it easy for them to pick and choose which patches they’d adopt. Now, it’s much harder both to do this and to copycat RHEL.

As Joe Brockmeier aptly put it, “It’s sort of like asking someone for a recipe for the family’s chocolate chip cookies, and getting cookie batter instead.” Sure you can tease out what the ingredients are, but it’s not easy.
