Online computer science archives

Those gents over at Lambda the Ultimate have a nice list of online computer science archives. I read stuff like this for fun, so I thought I’d archive this here so I can find it again.

Incidently, does the following character: — λ — look like a lambda to you? In Bitstream Vera Sans, it looks like a delta in Firefox at certain sizes. Bizarre.

Update: How ’bout this character: λ? Still looks bad to me… This is with the direct Unicode specification, rather than λ…

Choice alone is not enough

My blog is mostly a lark. Someone once said that sports were invented just so men would have something to talk about besides themselves and their feelings when they congregate in groups, and this blog serves much the same purpose.

But some people think bigger thoughts, and I enjoy reading their blogs too. Again, I found myself back at Lisa’s blog, where she is talking about the role of choice in society, and why choice is not enough. Go ahead, wander over there and read it, then come back. I’ll still be here…

Okay, just a few things to add. The problem with a society which says “oh well, they made their choice” is that often the individual under consideration didn’t really make a choice, at least not in the sense of “weighing the alternatives and picking a rational course of action”. Most teenage mothers don’t really make an informed choice about becoming parents. Most individuals don’t make informed choices about drugs and alcohol. And perhaps most notably, people don’t make informed choices which result in their living in poverty.

It’s a neat, tidy philosophy to presume that everything which happens to a person is solely their fault and solely their responsibility. It’s just not a very realistic one. The poor are largely poor because their parents were poor. Teen mothers are often teen mothers because their mothers were. Very few of us have the perspective, knowledge and control over a large enough segment of our lives to actually have any real effective choices about our lives.

Consider a reasonably popular idea: the idea of “giving choice” to parents in where they send their kids to school. Politicians have promoted the use of school vouchers, which would give the parents a choice of either attending a public school, or opting out and sending their child to a private school and receiving a voucher to help pay for this private school. Proponents would say this is a great thing, because parents now have a choice.

But do they really have a choice? The amount of these vouchers is not sufficient to fund attendance at a private school if you are poor, so for poor parents (presumably, those in most need of help) this represents no real choice at all. If you come from a well-to-do family, then you already could afford to send your child to a private school, so this doesn’t expand the choices available to you at all. If you are in the middle, where private schools were just slightly out of reach, you may have an additional choice, but here’s the rub: private schools are under no obligation to educate anyone for any particular price. Therefore, they could just charge more money to all their current (well-to-do) students), make higher profits, and continue to be out of the price range of middle income parents. So in fact, no one here gets any more choices at all.

Some of our choices aren’t really choices at all.

Compressed Filesystems

While investigating the creation of my own Knoppix distribution, I encountered a reference to the FreeSBIE project, which is a LiveCD version of my personal favorite OS, FreeBSD. With minor digging, it appeared that FreeSBIE takes a similar approach to Knoppix, and uses a compressed ISO image. This requires using 5.X and the new GEOM disk subsystem, and the details are here. Nifty! Basically, you can mount a compressed ISO file system just like any other device using the geom_ugz kernel module.

Brewster Kahle – Universal Access to All Knowledge

I met Brewster Kahle a couple of years ago at Hackers, when he brought the Internet Bookmobile and printed attendees copies of Alice in Wonderland and let us bind and cut them for ourselves. Here is an episode of IT Conversations where he talks about the ideal of providing accessibility to all knowledge for everyone.

Big thoughts for a Wednesday, but you can handle it.

Brainwagon Radio: Live Linux CDs!

Business card CD blanks can hold 50Mbytes, enough to boot Damn Small LinuxAnother mobile podcast, recorded with my Dell Axim x50v PDA and Resco Audio Recorder. This morning I chat a bit about various LiveCDs on Linux, and muse about the possibility of a specialized LiveCD for podcasting.

Links from the show:

  • Knoppix is probably the best known Linux LiveCD. Daniel Barlow’s Linux Journal article talks about mastering your own version of Knoppix.
  • Damn Small Linux is a bit more petite, and therefore a bit cuter. It fits on one of those business card sized CD blanks like the one pictured on the right.
  • dynebolic is more idiosyncratic, but targets music and media applications.
  • geexbox turns your PC into a media player.
  • I’ve also had good experience with Ubuntu, which also has a LiveCD.
