Rangefinders 0 cmts

This morning I went for a bike ride along the Minuteman trail. My intent was to check out the part near me that I didn’t know existed, instead I would up going all the way to the end. A few miles in I came upon a girl who was going at my same pace, and I ended up following her all the way out to Bedford. I stopped for a drink of water and then turned around, only to find that she had just started back as well. The path was beautiful: amazing foliage and great weather and light traffic (at least at the beginning). I just sort of kept going, with the mysterious rider ahead of me urging me on, going the perfect speed, passing all the slow pokes and joggers and people with their kids, until a few miles from the end I stopped at Trader Joe’s for some groceries and she kept riding, disappearing into the distance.

The ride felt easy, but I guess by the end I was more tired than I realized, because a quarter mile from home I ran into a railing and fell over, which was pretty embarrassing, and then a few hours after I got back I fell asleep. Still, 20 miles and no aches or pains (besides where I hit the ground), so I guess I must be getting into better shape after all.

“Incompetent people implementing security solutions” 1 cmts

Slashdot has an article on “when not to use chroot” which links to a KernelTrap discussion. The basic summary is, there is a UNIX command that lets you change the root (top level) directory to somewhere else, and it is effective for several sysadmin tasks, including “jailing” programs by making sure they can’t see anything other than the files necessary for them to run.

I’ve used chroots several times to fix systems with bad kernels. I’ve used chroots to compile Debian software. I’ve used them to bootstrap system installs. And I’ve used them, in fact continue to use them, even as we speak, for security. And I like to think that I’m not incompetent.

In any endeavor there are people with different levels of skill. I know that I’m not on top in terms of Linux expertise — there are people who were doing Linux before I even had a computer. But I do cringe when I see this sort of ridiculous blanket criticism of a commonly used implementation of a versatile tool. So Bill Joy invented chroots in the 70s because he was having problems with some compiler. Who cares. Today many important programs use or support chroots for improved security, and they do it because it works. So why the need to call people who use tools in effective ways idiots, just because they aren’t using something as it was originally intended?

That sounds like the sort of thing an Apple CEO should say, not an open-source kernel hacker. It’s sort of sad, really. Meanwhile, a have two dozen Apaches humming away, safely jailed in their own chroots, serving up web pages as they have been doing for the last year and a half.

Amazon’s new MP3 store rocks! 0 cmts

It’s “in beta” but they’re offering high-quality 256kbps VBR MP3s, album artwork, and *no DRM*. They have a ton of music, most of it priced at $0.89 per track and $8.99 per album. They have a simple little downloader app that automatically adds the music to iTunes (or Windows Media Player). Since it is DRM free you can put it on any portable device or computer you’d like and even share songs with friends and family. Except for selection, Amazon’s new MP3 store is superior in every way to the iTunes Store.

Oh Orson Scott Card, how you’ve fallen 0 cmts

Orson Scott Card offers a Christmas gift to his millions of fans with this short novel set during Ender’s first years at the Battle School where it is forbidden to celebrate religious holidays.

The children come from many nations, many religions; while they are being trained for war, religious conflict between them is not on the curriculum. But Dink Meeker, one of the older students, doesn’t see it that way. He thinks that giving gifts isn’t exactly a religious observation, and on Sinterklaas Day he tucks a present into another student’s shoe.

This small act of rebellion sets off a battle royal between the students and the staff, but some surprising alliances form when Ender comes up against a new student, Zeck Morgan. The War over Santa Claus will force everyone to make a choice.

Change is coming 0 cmts

I’ve been growing dissatisfied with the design of this blog for a while now, but was never able to come up with a new design that is both visually pleasing, more functional, and, most importantly, easy to implement.

A few weeks ago I came up with a design I’m really happy with. I designed it with the powerful and customizable K2 theme in mind, and am actually sorta surprised that I’ve been so successful in overlaying my design and functionality on top of that very powerful but visually restricted theme.

The new design is going to bring some important improvements: a wider page, larger, more readable text, and, my favorite, a much better way of posting and displaying links, quotations, pictures, and the like. I think that putting all the different types of content I like to post on an equal visual footing is going to be really useful. Unfortunately it means I need to go back through my voluminous archives and reformat a ton of posts to match the new way of doing things. Which is going to take some time.

Still, with any luck, I hope to have the new design up and running in the next week or so, even if some of the older entries aren’t going to display properly (at first). Stay tuned, its an exciting time. :)
