Software Freedom Day

I just learned about Software Freedom Day: today, 20 September!


Software Freedom Day (SFD) is a worldwide celebration of Free and Open Source Software (FOSS). Our goal in this celebration is to educate the worldwide public about of the benefits of using high quality FOSS in education, in government, at home, and in business -- in short, everywhere!


I don't have much time to research and write the article I would like to write in support of this. I am a big supporter of free software ("free as in speech, not free as in beer"), and hope to include a line of articles on it in this blog when I have more time (whenever that might be).

For the moment, let me just give a little anecdote:

My dad is a farmer in Alberta. He uses a computer for accounting, word processing, e-mail. It is important, because one of his main operations is a mail-order seed-potato business, Eagle Creek Seed Potatoes with a website for people to browse and order from. (He grows several very interesting and exotic varieties of potatoes for gardeners across Canada.) My brother farms with him, growing u-pick flowers and a very popular sunmaze.*

They recently got attacked by an e-mail virus that just about did them out of internet access - a serious problem for an internet-dependent business.

We were visiting Canada at the time, and I suggested trying Linux (specifically Ubuntu, one of the most human-friendly varieties of Linux). They put Linux on the infected machine, got the e-mail client running within the day (it's at least as easy as it is on Windows), and are now 99% virus-proof.

While we were at it, we put Xubuntu, a low-spec variety of Ubuntu, on a laptop that could no longer handle the demands of Windows, and suddenly they had one more usable computer than they had before.

A very short learning curve (about the same as you'd get moving from one version of Windows to the next) and they were all up and running.

Moral: if you don't want to spend money on virus-prone operating systems or on the latest and greatest computer, but just need something that works easily, reliably, and safely, Linux is the way to go. (Free Software is marketed as "free as in speech, not free as in beer", but it's usually both.)

And even if you don't want to go so far as trying Linux (even though it's very easy), there is a lot of useful free software out there that you can use in Windows or on the Mac. Try OpenOffice.org, which has a word processer, a spreadsheet, and most of the applications and features that Microsoft Office has. Try the Gimp, an image processing program akin to Photoshop. And for the love of all things digital, make sure you're using Mozilla Firefox rather than Explorer!

That's all for now. Enjoy Sofware Freedom Day!

*Note: Yes, I am shamelessly promoting my family's businesses here. Go, visit them, try the maze, grow some potatoes.

Life after death

We received the latest edition today of Humanitie, the quarterly magazine of the Humanist Society of Scotland. In it is this, my first (paid!) column in a series - accompanied by a twin column authored by Mike, the Not Quite So Friendly Humanist. The theme of this quarter's issue is death.

In April, I went with the local student linguistics club to the anatomy lab of a teaching hospital. I have studied the physical and psychological processes of speech for ten years, but I had never before seen the speech organs in place; never seen everything connected as it is in life. That visit greatly enriched my education.

If the anatomy lab is so helpful to a linguist, imagine the benefit to medical students and to those whose lives they will go on to save.

It's not all learning and delight, though. Stepping into the room, seeing the tables with the unmistakably human forms under sheets, I felt a stab in my heart - the visceral tragedy of death. Students of anatomy must acknowledge and respect the humanity - the sacredness - of the bodies being studied, while remaining detached enough to learn what there is to learn. Afterwards, one of my fellow students asked, "Did anyone else feel sad after the visit?" Yes, we did. This knowledge we had gained, this understanding, was only possible because people had died.

But the choice before us is not between their life and our knowledge. The choice is what to do when death comes. Though we were uneasy at times, I do not think anyone in our group regretted the experience, nor failed to appreciate the gravity of the choices and events that made it possible.

Because of that trip, I have decided to donate my body.

I've heard (and can imagine) many reasons for not donating one's body. They range from the superstitious - "What if my spirit can't move on because my body was not put to rest properly?" - to the self-conscious - "Do I want so many young medical students peering into my body?" These worries are real; but can they compete against the undeniable and tangible benefits the gift of one's body provides?

Simply put, yes. People's fear in contemplating such donations is immediate and profound. The fear of death cannot be set aside with a quick dose of reason; the prospect of having their body (or the body of a loved one) treated other than how they wish after death can cause true emotional distress. I would be a poor humanist indeed if I were to ignore such pain just because it isn't rational.

Nevertheless, medical students still need human bodies to learn from. The days of the Resurrection Men, and the grisly Burke and Hare murders, are well behind us. Today, the utmost respect is shown to donated bodies. But, as in the days of the Edinburgh grave robbers, there is always a shortage. Universities are forced to exploit alternative means of anatomical instruction - sometimes ingenious, but never quite as good as the real thing.

The gift of one's body suits every bit of humanist philosophy: care for others, value for education, and a dedication to reality over superstition and wishful thinking. I can think of few better epitaphs than on the marker of the plot used to inter the remains from the anatomy lab I visited: "To those far-sighted people who have contributed to the advancement of medical science & research."

The decision is deeply personal, and I do not condemn those who choose differently from me. But I do ask that you think about it. (Perhaps many people don't donate their bodies because it just doesn't occur to them.) Ask yourself which option accords best with your values and your beliefs.

Contact your nearest medical school to find out more about arranging the donation of your body.

Earth birthday

Another Cosmic Calendar event already!

Only the day after the Solar System begins to form, our own humble planet comes into being.

(Remember, because we are compressing the entire history of the cosmos into one year, each day represents 37.4 million years.*)



I apologize for not having more to say just now - I am still in PhD write-up mode.

[1] Wikipedia, as usual.
[2] Talk Origins page on dating the age of the Earth

* For those who have followed this series from the beginning, you might remember that I claimed before the each day is 41 million years. I am now calling it 37.4 million. What gives? The earlier figure was based on a 15 billion-year-old universe. I have since learned that the consensus is for a slightly younger universe, at 13.7 billion years. Remember, this is a calendar based on what we know, and so when what we know changes, so does the calendar. If anyone else wants to fact-check my figures and calculations, please let me know.

Solar System forms

[For those of you who enjoyed the Cosmic Calendar posts in December (here and here), I must apologize for the dearth of them so far this year. Not much happens before December, but I did miss announcing the formation of the Milky Way galaxy back on April 6th (10.1 billion years ago).]


Some time about 4.6 billion years ago, our solar system began forming from a large cloud of dust and gas. In the Cosmic Calendar, that corresponds to today. So ... happy Solar System Day, everybody!

Next up ... birth of the Earth.

[1] The Wikipedia article on the Formation and evolution of the Solar System reports the cloud from which it formed starting to collapse about 4.6 billion years ago. That's also where I got the pretty picture, which is a public-domain depiction courtesy of NASA.
[2] The Natural History Museum reports an age of 4.5 billion years - slightly different (two days later in the Cosmic calendar). As the formation of the solar system probably took some time, any specific moment chosen as its "formation date" (birthday?) will be somewhat arbitrary.

Test your ear for language

There's a fun game for anyone who is curious about world languages. It's the Language Quiz on Simon Ager's Omniglot blog: he posts a short recording of a language, and you get to guess which language it is.

After several months of playing , I've only once guessed the right language. Well, this recent quiz is especially intriguing, so I thought I'd share it with you. Warning: the answer has already been given in the comments, so try listening first before you read them. (It's tough, because the comments appear right below the text of the very short post.)

If, after listening, guessing, and checking your answer, you want to know why this is my favorite one so far, ask me in the comments and I'll tell you. (I'd do it here in the post itself, but I don't want to give away the answer before you try the quiz.)

Myers on meaning

At the end of a post about convergent evolution (and its misinterpretations), P.Z. Myers, author of the Pharyngula blog, gives these thoughts about meaning and purpose:
We are each our own individual engines of purpose, operating in a hostile universe where randomness can shape our fates. There is no grand scheme behind our existence, other than the same function that all our ancestors had: to order our local environment to allow each to survive and to make the world a little better for our progeny. And that's enough — that's all that is needed to make a rich, diverse, living planet, and it's all I need to live a satisfying life.
What a heartfelt summary of meaning in a naturalistic worldview. Thankyou, P.Z.!

The Downfall of Literalism

I've seen the Cake Wrecks blog a couple of times, but I have to say that being pointed to this entry by a religious blogger (Ken at C. Orthodoxy) made my day.

Thanks Ken. (Who ever said that rationalists don't have allies in the religious community?)

[Note: I am still finishing my PhD, so posts will continue to be sporadic and brief for at least a few weeks. I promise exciting things to come, so please bear with me!]
