Compound Boolean Geometry

Well, converting from simple boolean geometry code to Compound boolean geometry code wasn't quite as simple as I first thought. BUT, it wasn't too bad either. Basically, you just have to do the same inside/outside/shared/unshared tagging that you do with simple paths, and apply it to all subpaths as well. There's some fiddly bits about making sure you are inside an odd number of the opposite path set's paths, but it wasn't too bad. The result is shown below:

I've been working on getting my CAD/CAM program up to snuff with basic stuff like, oh, Grouping/Ungrouping objects, and getting SVG import/export working. Part of this has gotten me to revisit some code that I had stopped working on out of frustration.

My Boolean Geometry code.

This is code that is supposed to let you take two or more polygons and join them into one object, or subtract one from the other, or get just the regions that are common to both polygons. This is incredibly useful code when you are trying to make milling paths in CNC work. But until now, my code was just plain broken.

As with many complicated tasks, a few months working on other code has let the design simmer in the back of my brain, and as I finally come back to it, now the design is both obvious and simple to me, so I coded it up, and it now works for simple closed polygons. (Compound polygons are slightly more complex, but with the basics in place, won't be a big deal to finish.)

For folks on the net searching for the solution to this topic, I give an explanation of my algorithm behind this cut tag. )

Belfry.com and belfrycomics.net are down at the moment. Our ISP did some scheduled maintenance tonight, and when they brought my server back up, the hard drive made godawful noises and wouldn't mount. Luckily we have backups, but it may take me a day or two to restore from them.

I'll post more info when I have it.

For those of you running OS X, did you know you can use spotlight like a calculator? Just open the spotlight search field and type the equation you want to calculate. But beware, as spotlight has a bug! If I type "3*3" (or various other simple calculations (without the quotes)) into my spotlight window, it crashes a moment later. But there is a workaround; just put a decimal after the first number. Ie: "3.*3"

When working in the tech sector, it's a truism that in a bad economy, "the contractors are the first against the wall" to get axed.

Come January 30th, I'm the one against the wall at my current gig.

Meh. I'd half suspected I was training my (cheaper employee) replacement. So, no real surprise here. Just vaguely annoying.

On the plus side, my manager gave me a glowing review to my contracting house. Yay!

Now I get to do intense job hunting before the last of my money runs out.

More heretical musings

  • Nov. 5th, 2008 at 2:01 AM
wicked / dangerous
One of the big reasons I get told as to why folks support(ed) CA Prop 8, is that "...Marriage is a sacred religious institution" and their religion says that it should only be between a man and a woman.

Okay, I can almost see that.

Except... then why are atheists allowed to marry? That seems highly inconsistent. Un-ordained Justices-of-the-Peace or ship's captains shouldn't be allowed to preside over marriages if they are supposed to be Sacred and Holy. And what about folks from other religions that are fine with gays marrying? Is it okay, only for them?

My dad was an atheist. Does this mean that my parents should not have been allowed to marry? That I should have been born a bastard? Though that's pretty frowned on too... I suppose the strictly logical conclusion here, based on the given premise, is that in the ideal world of sacred marriage, I would just not have been born.

...

Perhaps unsurprisingly, I cannot really find it in myself to support this position.

But really, lets be honest here... which of the following cheapens the institution of marriage more?
  • Two women who love each other and want to marry?
  • Two atheists getting an elvis impersonator to marry them?
  • The fact that around 41% of all first marriages, 60% of second marriages, and 73% of third marriages end in divorce?

Why is it that divorce is legal, and atheists marrying is fine, yet somehow gays marrying is such a horror that the state constitution has to be changed to forbid it? As a friend of mine put it, "King Henry VIII did way more damage to the institution of marriage than Gays have."

Consistency, people! Be consistent!


I would have posted this before the election, except that I'm mostly preaching to the choir here. The few exceptions are folks whose vote I could not have swayed anyways. But I've had this rant running in the back of my head for a week now, and it wanted out.

Logical musings

Lets assume that California Proposition 8 passes, and marriage gets defined as between a man and a woman.

Given the CA supreme court's earlier decision:
The state Constitution's guarantees of personal privacy and autonomy protect "the right of an individual to establish a legally recognized family with the person of one's choice," said Chief Justice Ronald George, who wrote the 121-page majority opinion. He said the Constitution "properly must be interpreted to guarantee this basic civil right to all Californians, whether gay or heterosexual, and to same-sex couples as well as opposite-sex couples." - SFGate.com


Prop 8 defines marriage, but it says nothing at all to the effect that Gays shouldn't be allowed equality. It tries to imply it, but it's just defining a word.

So lets run with that. How does Prop 8 interact with the equality established otherwise in the CA constitution?

Logically it seems to me that the only way to make those two work together is if it is interpreted that any unequal benefits that are afforded to married couples should be deemed unconstitutional. How would that be handled for federal marriage benefits, though? Should the logical result of Prop 8 be that the CA tax code would have to be modified to exactly counteract any federal benefits for marriage?

It seems like it'd only be fair.

At this point, McCain would have to walk on water, and perform two other scientifically verified miracles right in front of me, before I would vote for his ticket.

It's not his policies. I actually agree with about half of them. It's not his age, though his relative mortality is a worry. It's not that he's a Republican. I actually had a lot of respect for McCain until this last year, and I currently rather like my state's Republican governor.

No, the reason that I cannot envision voting for McCain/Palin is that their campaign has devolved into disrespectful, dishonorable, unfounded character attacks. It's gotten so ugly that a rally with Sarah Palin now sounds like a mob getting whipped up into a racist/McCarthyist hateful froth. It's so bad that even McCain had to defend Obama at one of his own rallies. I had regained a bit of respect for McCain for that, except then he later went on to repeat the terrorist link allegations, and that Obama had Socialist (implying communist) policies.

Palin is unapologetic about getting folks worked up at her rallies, without stopping them when they get to yelling that Obama is a (Muslim / Communist / Terrorist). She uses Obama's middle name as a weapon to try to strengthen the terrorist association in weak minds. (Never mind that Hussein is about as common as Smith, as names go in this world.) Palin works with Fear and Anger. And, to a letter extent, so does McCain.

I used to respect McCain, but I really, really disrespect his choice in campaign tactics. His choice in running mates has shown to me just how unfortunate his judgement is. I have no respect for Palin. In fact, I fear her getting anywhere near the oval office. She sounds too much like the old films to me. The ones they used to play in the 50's and 60's, as a warning about How Bad Governments Form.

I probably wouldn't vote for McCain even if it were just him, due to how he has run his campaign. But there is no way in hell that I'm going to help Sarah Palin get anywhere near to becoming President.

America is supposed to be about dreams, ingenuity and spirit, NOT about fear.

Having lost most the money I had by being out of work all last year, at least I don't have much left to lose while the financial world melts down, except perhaps my new job. And watching the tech sector stocks melt down a bit today, that's not looking so certain to me at this point either.

In the movie "Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb", there's this scene where Major T.J. "King" Kong, played by Slim Pickens has to manually fix the bomb drop mechanism on the nuke he's about to drop in Russia. He gets it working, and rides the bomb down down to detonation, like a bronco, whooping and hollering and waving hit cowboy hat around like he's having a grand old time. Then boom. Then the rest of the world goes boom, as the doomsday weapon goes off in a montage of nuclear doom.

I'm starting to feel like Slim there, watching the markets. Not a damned thing I can do about them. I've spent years pointing out various signs, but it's too late now. So I might as well get the popcorn and whoop it up as the folks who started this mess go down in flames so hard that they take the rest of us with them.

See you all in the post-crash Second Great Depression. (I call dibs on the name GD2.)

Moribito

I'm... stunned. Cartoon Network finally has a new Anime that actually makes me want to watch.

It's called Moribito, and it's good. Fantastically detailed backgrounds... Interesting story... Characters that don't make me hate them in ten minutes... My only complaint so far is that the main character has the same voice actor as Motoko Kusinagi from Ghost in the Shell, which causes me minor mental dissonance. Though as I think on it, both characters have similar strong personality types, so it kinda fits.

It played its first episode on Adult Swim on Cartoon Network today, and I highly recommend it.
