2012’s Best Linux desktop: Linux Mint 13

The very popular Linux distribution, Mint, has a new version Linux Mint 13, Maya, and a new take on the GNOME 3.x desktop interface: Cinnamon 1.4. The result is, in my opinion, the best Linux desktop for experienced users to date.

Not everyone will agree with me. They’ll find Mint’s other default desktop MATE to be much more their speed. MATE is a fork of that old Linux desktop favorite, GNOME 2.x. While I haven’t looked at the MATE edition of GNOME closely, other Linux reviewers, like Jim Lynch, have and Lynch likes what he’s seen of Mint 13 paired with MATE.

Setting up Mint 13: 2012’s Best Linux desktop

Even with the little work I’ve done with MATE though I can see what GNOME 2.x fans will like it. It’s a very clean desktop and it feels and works like a natural extension of GNOME 2. GNOME fans who abandoned GNOME after the annoying changes in GNOME 3.x for Lightweight X11 Desktop Environment (LXDE) will want to give Mint with MATE a try. With MATE, GNOME 2.x is back.

Open source and the National Security Agency, together again

The Open Source Software Institute, a non-profit group that supports open-source adoption and the National Security Agency (NSA), the organization in charge of all out of country eavesdropping, will co-host an Open Source Software Industry Day on Wednesday, May 30, 2012. The unclassified, one-day event will be held at the Johns Hopkins University Applied Physics Laboratory’s Kossiakoff Conference Center near Fort Meade, MD, which is where the NSA is based. Alas, pre-registration is already over.

If you were one of the lucky 640 to make it in, you’ll get to hear about agency’s interest in opportunities made available through open source software solutions. Yes, the NSA is looking for a few good spooks. The conference’s speakers will present information on existing open-source software products, as well as service and support offerings; and encourage government suppliers to include open-source options in their strategies and service offerings.

Why WiDi wins and losses for your computer/TV connection

When I first got started with personal computers, I often used a TV to show computer video. Well, to be more exact, I didn’t have any choice but to use a TV as a monitor to display CP/M-80 command line interfaces. There’s been a lot of changes since the 80s, but getting your PC video to your TV is still something of a pain. True, you can hook up an HDMI cable to do the job, but I’ve never been a fan of having cables running across my living room. I’m also no fan of using a Bluetooth keyboard and mouse, with their limited range, to talk to the PC media server. No, what I really wanted was a way to just have my laptop in front of me and then just throw my video from my 15.6” laptop display to my 42” HDTC TV without any fuss. That’s what Wi-Fi Direct (WiDi) promises. Unfortunately, there’s still trouble with it delivering the goods.

WiDi has been certified for over a year and a half now. Based on 802.11n technology, WiDi is backwards compatible with the 2.4 and 5GHz Wi-Fi networking family and uses WPA2 security. However, it’s used more like Bluetooth, albeit it with much greater range, than a LAN technology.

It’s meant to make direct connection quickly and easily from PCs to printers, displays, and so on. To do this, instead of switches, routers, or access points, WiDi devices incorporate software access points to enable ad hoc point-to-point networks. The case I care about is the one of connecting my WiDI enabled laptop with a similarly equipped TV.

Dumb ideas? Facebook to buy Opera? Build own smartphone?

According to Pocket-lint, sources close to Facebook have told them that the newly IPOed social networking company is considering buying Opera Software, the Opera Web browser’s parent company. Another rumor has it that Facebook wants to build its own smartphone. I don’t see either move making a lot of sense.

If Facebook were to buy Opera Software, its price might be on the same order as the billion plus it paid for Instagram. Opera currently has a market cap of $679-million. In addition, Opera has a small, but loyal, number of users. Still, loyal as they may be, Opera has long trailed Chrome, Internet Explorer, Firefox, and Safari in sheer number of users. In April 2012, by StatCounter’s numbers, Opera only had 1.72% of the world Web browser market. This leaves it, as it has been for years, solidly in last place in the Web browser derby.

In short, Facebook certainly wouldn’t be increasing its market-share with its own Web browser. Heck, Facebook doesn’t even list Opera as one of its supported browsers.

There’s trouble with three major Linux desktop application developers

The Linux desktop has long had most of the apps anyone could ever really need. Sure, it doesn’t have some specific applications, like Adobe Photoshop or Quicken, but it had other apps. Such as Gimp for Photoshop and GNUCash for Quicken and QuickBooks that can do the job. Lately, however, companies that have supported Linux are moving away from the Linux desktop and that worries me. These companies and groups are: Adobe, Google, and Mozilla.

The first one doesn’t come as much of a surprise. Adobe has long had a “difficult” relationship with Linux. We, the Linux community, wanted the full Adobe suite and what we got was Adobe AIR, Flash, and Acrobat. Well, we used to get AIR and Flash anyway. In February, Adobe announced that Adobe Flash Player 11.2 would be the last native version for Linux.

Newer versions of Flash will still be available for Linux… if you use the Chrome Web browser with its Flash Player browser plug-in. Listen, I love the Chrome Web browser, but I don’t love feeling like I’m forced to use it because Adobe won’t release a universal plug-in for any browser.

Google kicks Oracle in its patent teeth

I get to say I was right again. First, I told you so when I said the Facebook IPO was dead in the water and now I get to say I was right about Oracle’s Java patent claims being next to worthless in its case against Google and Android. Oracle vs. Google has been a dead lawsuit walking all along, and now as I suspected it would, the jury has ruled that Google didn’t infringe on Oracle’s patents. Game, set, and almost the match to Google.

To be exact, the U.S. District Court of Northern California jury ruled unanimously that Google did not infringe on six claims in U.S. Patent RE38,104 as two claims in U.S. Patent number 6,061,520.

Not mind you, that it would have mattered much had the jury ruled the other way. As Oracle’s own expert, Boston University professor Iain Cockburn had said earlier, even if Google were found guilty on all those counts, Oracle would had won maximum damages of $32.3-million. Oracle may have spent more than that every month keeping this case going.

After the verdict, Judge William Alsup dismissed the jurors, and said he’d be deciding on the related application programming interface (API) copyright issue next week. I find it highly unlikely that he’ll rule that APIs can be copyrighted.
