One Tale of Two Scientific Distros
September 1st, 2008 by Doc Searls
Several weeks ago, I was flying west past Chicago, watching the ground slide by below, when I spotted the signature figure eight of the Fermi National Accelerator Laboratory, better known as Fermilab. I shot some pictures, which I put up at the Linux Journal Flickr pool (Flickr also uses Linux).

When does communications become spam?
September 4th, 2008 by David Lane
An issue near and dear to my heart, both personally and professionally is that of spam. Not the lunch meat, which, when prepared correctly, I happen to enjoy, but that bane of email, the unsolicited commercial email (UCE). At what point does legitimate communication cross the line to become junk.
On standards and standards bodies
September 3rd, 2008 by David Lane
What does it mean to be open.
My copy of Oxford defines open as: unconcealed circumstances or condition. Way back in the day when the GNU operating system was getting going, they coined the mantra: Free software is a matter of liberty, not price. To understand the concept, you should think of free as in free speech, not as in free beer.
Watch Africa Today
September 2nd, 2008 by Doc Searls
"In Africa people are much more attuned to blogs than you'd think." Ethan Zuckerman just said that. (You might remember Ethan from GeekCorps.) It's one quotable line among a cascade of them. And he hasn't even gotten around to the remarkable Eric Osiakwan yet. Both are talking about The Climate of Innovation Around Information Technology in Sub-Saharan Africa, the topic of today's luncheon at the Berkman Center. It's being streamed live, and it's so different from the usual geek fare — yet both geeky and extremely important for both Kenya and Africa.
Quebec government being sued, for buying Microsoft!
August 28th, 2008 by marcel
This certainly qualifies as an interesting development. CBC is reporting that FACIL, a non-profit organization that promotes the adoption of free software in Quebec, is suing the provincial government for buying Microsoft software. More specifically, they are alleging that Quebec's provincial government refuses to allow competing bids (including bids from free software vendors) in preference of large players like Microsoft. Allow me to quote from the CBC article.

Where are we on 508 compliance?
August 27th, 2008 by David Lane
As a computer professional I take my sight for granted. Think about it, how much you rely on your eyes. How much of what we do is based on what is on the screen and where it is on the screen.
The Death of the Letter?
August 26th, 2008 by David Lane
BALTIMORE (AP) - Mailboxes are going the way of phone booths. More of us are paying our bills online and using the Internet to send our correspondence, so the U.S. Postal Service has decided it needs fewer mailboxes. (WTOP)
Could Microsoft's Photosynth Have Been Free Software?
August 26th, 2008 by Glyn Moody
Photosynth is one of the most exciting programs I've seen in a long time. It takes a group of photos, typically of a single geographical location, but possibly taken at different times by different people, analyses them for similarities, and then stitches then together into a smooth-flowing, pseudo-3D panorama. It's really great. Just two problems. One: it won't run on GNU/Linux; and two: it's from Microsoft, and so is unlikely ever to do so.
My question is this: Why didn't the free software community come up with Photosynth first?
How do we attract the next generation?
August 22nd, 2008 by David Lane
What are we doing to expose new users to Linux and Open Source solutions? My wife, after coming back from a visit to our local electronics store asked me why there were no “boxes” of Linux on the shelves, or PCs supporting the OS on display?

Feeling a bit like a Thermian? Never give up, never surrender! Someday, you could go from underdog to top dog. Just take a look at a few of the underdogs we highlight in this issue: Mutt, djbdns, Nginix, Gentoo, Xara and the program voted mostly likely to fail just a few years back—Firefox.
