On The Radio

Sorry for the short notice–it slipped my mind. I’m going to be live on The Space Show with David Livingston in about an hour. On the air in the Seattle area, and there’s an internet feed here.

[Update afterward]

The interview went well, but I found out it wasn’t broadcast live (thought it was on the internet). It was taped for a later broadcast. I also want to remind people that Bill Simon (transterrestrial webmaster) and I will be on the show next Tuesday. It’s the thirty-fifth anniversary of the first Apollo landing, and we’ll be talking about that, and the sedar-like ceremony that we developed to commemorate it.

If you’re really into the significance of that date, it would be a good time to gather with family and friends, and have a dinner to help remember the first liberation of our species (and earthly life itself) from its homeworld, just as the Jews celebrate their liberation from Egypt at Passover.

Despite all the saturation coverage of space in the past year and a half, it would seem that we need such tools to educate ourselves about this new frontier, as Jay Manifold sadly points out today.

I Still Want My DNS!

The saga continues.

When I hardwire a DNS into my client, it works. Sort of.

I can get to transterrestrial.com, but pages from Instapundit and National Review (and who knows which else?) won’t load.

This is the case not only for my original solution of Earthlink’s IPs, but also for Dave Mercer’s recommendation of cybertrails.com’s.

What the heck is going on?

Rocketforge shwag, evolvable design

Mike Mealling over at RocketForge has added to his shwag offerings. In particular the Apollo LEM mug is cool, though the Skylab Mousepad is also quite geek-chic. I’m hoping he’ll add an RL-10 mug (hint).

I’m a big fan of the RL-10, since it’s as close to the realizing the ideal of evolvable design as any spaceflight gadget that I’m aware of, having been in use since 1963, with continuous upgrades and improvements since then. It’s also the engine that was used (in yet another variant) on the DC-X, which is enough to earn it a spot in space history even without the large number of variants. I suspect that there are Russian engines which come close to the RL-10 in realizing evolvable design, but none pop immediately to mind (a reflection of ignorance more than anything else).

I’d be interested to hear of other candidates for best realized evolvable design in space hardware. Bear in mind that by “realized evolvable design” I mean not just design that is capable of incremental improvement, but design which has actually undergone substantial incremental improvement, or which has spawned a large number of useful variants. Soyuz is one obvious candidate. I suspect that there are Russian spacesuit designs which also meet the criteria for realized evolvable design.

This post honestly started out as just a pointer to the new RocketForge mug, but obviously I’m in a bit of a rambling frame of mind. For more on why you too should be a fan of the RL-10, check out the relevant collection of archived Usenet posts on Yarchive.

Some patent thoughts

One of the things I did in my dissolute holiday was play Texas Hold’em with Dan Barry, among other people. The first thing in my inbox when I got back was an email from my advisor asking if I’d be willing to help someone with some patent advice. Among the first websites I visited when I got back was The Space Review, on which there is an article advising space entrepreneurs on patents, using Texas Hold’em as an example. Bizarre little chain of coincidences. Not being superstitious I’m not trying to figure out the deeper meaning, but it’s a little odd.

Anyway, on the topic of patents, the article by Sam Dinkin is pretty much exactly on target, but I thought I’d mention the advice I always give people thinking about patenting an idea. This is based on all of six month’s experience doing IP work, so it’s far from definitive, but my job would have been simpler had I known it, so here goes: The most important thing to understand about patents is that they aren’t about ideas or inventions, they are about lawsuits. The only utility of a patent is in a lawsuit or threat of a lawsuit. If your idea is unlikely to be picked up by someone else, a patent is unlikely to help. Given that the time when people are thinking about patenting an idea is right at the beginning of their business, the money and time invested will often pay off better elsewhere, such as in building a proof of concept demo. A patent can be useful in scaring away competition, but that cuts both ways – if you think you can build a genuinely better mousetrap but it infringes someone else’s IP, all may not be lost. After all, it’s about a lawsuit, and the patent holder doesn’t always win – there are some really lousy patents out there.

Anyway, I’m repeating a bit of what Sam Dinkin said, but hopefully the repetition isn’t wasted. If you have a good idea that might be patentable, go read his article, and then go read what Don Lancaster has to say on the subject. Also, check out the EFF’s Patent Busting Project for some examples of some of the egregious stuff that manages to get patented. EFF is trying to bring some sanity to the subject but they could certainly use some help.

Now *That’s* A Vacation

You know you had a wild vacation when it takes two days to recover from it. You’d think that hanging out with a bunch of neuroscientists would be intellectually stimulating but perhaps a little light on the wild partying. You’d be wrong, at least about the partying part. The social scene surrounding the Marine Biological Laboratory is really something to behold. It was a long weekend, so there were parties every night for four straight nights, and all the parties were too good to leave before the wee hours. I ended up averaging about 5 hours sleep a night, which is nowhere near enough. Somehow biologists simply have better parties than physicists. I think it has to do with the average level of social skills. I know some very socially smooth physicists, but let’s face it – the average physics geek is a little on the dorky side, and a bunch of slightly dorky people all in the same place tend to condense into a big glob of mutually reinforcing dorkiness. Biology dorks don’t undergo the same transition, probably because they are fermion dorks, while physicists are boson dorks. Or something. There’s actually a coherent explanation for why biologist dorks should be fermionic (having to do with the greater degree of distinction between different subfields of biology), but something tells me that it would be better not to go there. Maybe I’m not yet fully recovered from my vacation 🙂

I Want My DNS!

OK, I finally got it working. Sort of. I can ping the LAN. I can ping the internet. I can even get to web sites if I know the IP. But when I ping an internet domain from a client with no IP (even something as simple as yahoo.com) it goes “Huh!” as only computers can do, and sits doing nothing.

Any ideas what I have to do to get ZA (and please, no more stories about what a fool I am to use ZA–those are not helpful at this point) to allow DNS? Or diagnostics I can run to figure out where the problem is?

[Update a few minutes later]

OK, I still don’t know why it’s not doing DNS properly, but I fixed it by assigning some DNS servers manually to the client (Earthlink’s). It seems to work now, but it also seems like a kludge.
