In the beginning, there was the word processor

nce upon a time, and it wasn’t that long ago, instead of word processors like today’s favorites such as Microsoft Word, Google Docs or OpenOffice and its brother LibreOffice, we had to use typewriters. Some of us, dare I admit it, wrote by hand on paper. The horror! The horror! But, then along came word processors and the world changed.

In my case, I made the change-over in 1980. I went from using my “prized” IBM Selectric II to using two word processors at almost the same time. I’ve always been a glutton for punishment.

The first, and the one that counts as a real word processor, was WordStar. I first used it on an Osborne 1 “luggable” computer. This was a portable computer only in the sense that if you absolutely had to move it, you could “lug” its 24-pounds from one place to another. Of course, you had to have a power outlet where-ever you went, we were a long, long way from having batteries that could power something like the new iPad for ten hours.

WordStar, which was God’s gift to touch-typists, made it possible to use the control key-at the time the only “alternative” key most PC keyboards had–to copy, cut, and paste text. While there were earlier word processors, Electric Pencil, WordStar was for many of us the first word processor we could use on a general purpose PC.

The new iPad’s great but what’s wrong with a good, inexpensive Android tablet?

Don’t get me wrong. I think the new iPad sounds wonderful. The retina screen, which Ray Soneria predicted, looks great. Even if its A5X processor isn’t as fast as Apple claims, it’s still amazing fast. And, while I really doubt that the iPad’s battery will really last as long as they claim it will, even if comes close it will still be amazing battery performance. But, still the cheapest model, the 16GB Wi-Fi only, is $499. Might I suggest that at $199 Barnes & Noble’s Android-powered Nook Tablet might be the better deal?

What’s that? Of course, I know the Nook Tablet only has a 7-inch display, only has Wi-Fi, has a much slower processor, only 8GBs of storage, no camera at all, and it only runs a simplified version of Android 2.3 (Gingerbread).

If I wanted to, I could boot the Nook Tablet into Android 4.0 (Ice Cream Sandwtch) with the brand new CyanogenMod 9. Once there, I’ve been able to add the usual Google Android apps to my modified Nook Tablet with the CyanogenMod 9 Google Apps package. But, while the geek in me rejoices in that, the ordinary user in me has found the simple Nook Tablet native interface to be just fine.

Still, there’s no question in my mind that the new iPad is the better tablet. I’ll get one. But, I can afford it. Can you?

NVIDIA joins the Linux Foundation

The Linux Foundation, the nonprofit organization dedicated to supporting Linux has announced that four companies are joining the organization: Fluendo, Lineo Solutions, Mocana, and NVIDIA. The big news here is that NVIDIA, the major graphic chip original equipment manufacturer (OEM), is finally officially supporting Linux.

Now that NVIDIA is a member of the Linux Foundation, all three of the major graphic chip designers–AMD Graphics Technologies (formerly ATI) and Intel–are backing Linux. NVIDIA, best known for its GeForce chipsets, has long had an uncomfortable relationship with Linux.

While NVIDIA has long shipped Linux graphic drivers and has kept its Linux drivers up-to-date, the drivers for their graphic processors have always used proprietary binary blobs. This meant free-software users couldn’t use the drivers and open-source developers couldn’t work on them to improve them.

Shuttleworth on the Ubuntu Linux 12.04 beta

Microsoft wants you to love Metro. Apple is bringing iOS and Mac OS X closer together with every release. But, Mark Shuttleworth, founder of Ubuntu Linux and its parent company Canonical, thinks that if you want “real desktop user experience innovation” … “before it shows up in Windows or MacOS,” you need to check out Ubuntu 12.04’s forthcoming Head Up Display (HUD).

In a blog posting, Shuttleworth wrote that while Ubuntu 12.04, Precise Pangolin, which just went to beta, is still far from “job done” the new HUD desktop is ready for a wider audience.

Linux patent defense group expands open-source protection

The Open Invention Network (OIN) has significantly expanded and updated the Linux System technologies covered by its protective network of royalty-free cross-licenses. Over 700 new software packages–including popular packages such as Kernel Virtual Machine (KVM), Git, OpenJDK, and WebKit–will now receive coverage. In addition, coverage for over 1,000 existing software packages has been updated. Soon, the OIN will also expand its protection over Linux-related mobile operating systems such as Android, MeeGo, Tizen, and webOS.

Patents owned by Open Invention Network are available royalty-free to any company, institution or individual that agrees not to assert its patents against the OIN’s broad Linux Definitions. The Open Invention Network license Is designed to spread patent protection among its members. This includes patent cross-licenses and releases from claims of patent infringement among its licensees. This, in turn, encourages collaboration between Linux companies. These patents could also be used to defend Linux vendors and developers from anti-Linux companies’ legal attacks.

The OIN was formed in 2005 by IBM, Sony, Philips, Red Hat, and Novell . Since then this Linux intellectual property (IP) defense group has grown by leaps and bounds. Today it has more than 360 members. Two of the most recent companies to join in OIN’s defense of Linux’s IP are Cisco and Twitter.

You can now run Arch & Debian Linux on a Raspberry Pi

Raspberry Pi, a credit-card sized computer that retails for $35, finally has some operating systems ready to run on it. A remix of Fedora Linux is still the “official” operating system for Raspberry Pi, but it’s been delayed. In the meantime, versions of Arch and Debian Linux are ready to go.

The Raspberry Pi Fedora Remix, which is based on the older Fedora 14 distribution, was designed to fit on a 2GB SD card. It will include the LXDE and XFCE, two popular lightweight Linux desktops and an assortment of popular open-source software. A version, using the more up to date Fedora 17, is also in the works.

Several problems have delayed both releases. This includes pushing audio out the HDMI and analog ports via PulseAudio and Advanced Linux Sound Architecture (ALSA). In addition, Chris Tyler, the man responsible for assembling the Raspberry Pi Remix, has been sick.

That said, there’s been no further word on the Raspberry Pi Fedora actual release for almost two weeks. On March 4th, Liam Fraser, who’s in charge of distributing the Raspberry Pi Fedora image, said he was “still waiting for an image from Chris but I do think that it is nearly ready.

This delay has understandably annoyed some Raspberry Pi fans.
