"Do you like our eye?"   "It's artificial?"
"Of course it is."   "Expensive?"   "Kinda."

So I saw a video of a Gakken WorldEye running it's bundled animations of planets rotating, and I thought, this might make a fun xscreensaver output device: it's probably just a matter of tweaking the gluPerspective parameters to de-fish-eye things in the right way. There aren't too many savers that would benefit from a 180° display -- actually maybe only glplanet, discoball, geodesicgears and sonar -- but it's worth investigating.

Then I saw a video of one with a giant eyeball on it, and I thought, "How did I not think of that! It's cool that someone put a pre-recorded MP4 of an eye on that thing, I should do something like that but really overengineer the living shit out of it."

But oh no, this was not necessary. @PaintYourDragon has done some fine work here. It is over-engineered well beyond what I had imagined. Customizable iris and sclera. Editable eyelid profile. Different eyelids for left, right and cyclops eyes. Pupil dilation controlled by a photoreceptor. Button inputs for blinking and winking. It's fantastic.

(I am actually slightly surprised that cat and goat-shaped pupils are not already supported. One must assume that that's coming in the next release.)

Anyway, the first WorldEye I ordered arrived non-functional. The firmware appears to be alive, but the little internal projector won't light up. I tore it apart and it lit up for a minute, but then stopped again, so there's probably some microscopic cracked trace somewhere. The second one worked fine, though.

There seems to be no way to make it default to HDMI input, so if it ever loses power it won't start looking at you without being fiddled with. But, it does provide enough juice on USB to run the Pi, so that's handy.

@mjg59 If a smart weapon running Linux fails to explode is the target entitled to the GPLed source code? "What is your one purpose in life?"

@BootlegGirl Yes, but if it's LGPL they can make the bomb itself proprietary. Ethical warmongers release weapons as CC0
@tveastman A missile is technically a deployment, and not just a distribution, so I guess the rules will be interesting for the AGPL too.
@dmarti The weapon must include a written offer to distribute the corresponding source. It doesn't matter if a recipient actually runs the software.
But what if the target is under trade embargo, and the sender can't actually fulfill the offer of source code? Do they still have a license?
@giladby I worked as a consultant on the Iron Done missile defence system It shoots Linux running missiles designed to intercept incoming missiles.
We debated many questions. If you target another missile, who you are distributing TO? Would incl. src code on missile enough to satisfy GPL
@geofft if they target civilians is it a "User Product" under GPLv3? "(2) anything designed or sold for incorporation into a dwelling"
@fanf I am reminded of the guidance computer that leaked memory about as fast as the rocket used fuel
@mk270 and those jokes about loops in Ada having "detonation" as a termination condition. Sends the Haskellers mental
@fanf C++ calls this kind of loop undefined behaviour
@vathpela Depends - would it be legal trade in the first place? (Pretty sure if the target is a State Sponsor of Terror, you can't have a contract...)
@the_lazyknight yes, but reasonable costs for the media may be be levied. So include the source on the warhead, then charge for the bomb.
@danhedron Yes, but there is no guarantee they can install their own unsigned version.
@elgarak Does this count as malware?
@schumaml Generalized, it becomes "If any device is used on you, do you become a user of the device?"
@uriy Yes, but to avoid breaking crypto/munitions export laws you should only use it against a friendly target.

Thought for the Day

I am sick of having to suffer so a man can grow. What is this, every Hollywood movie ever made? I am tired of having to confess to someone else’s crimes. I am tired of showing up at the banquet dripping blood like Banquo’s ghost. This should be your ghost, not mine. I am not the one who should be ashamed that you have done these things. I am not here to make you see the error of your ways. I am here to get through my life every day without inhaling thick lungfuls of smoke.

Because that’s what this is. This is like getting people who have gotten cancer from secondhand smoke to come testify together as a way of solving the problem. But you are the one who needs to stop.

Bio-Granddad

One day in the late 80s, I was back at my parents’ house, between semesters at University. “I think you look like my father,” my mother said, rather matter-of-factly, and somewhat out of the blue. She went off to another room of the house and came back with a cardboard stationery box that I had never seen before. Inside the box, she produced a large head shot photo of her father, Walter Dynes, for comparison purposes.

I’m pretty sure that I was in my early twenties. Until that moment, I had never her say a word about her father. I don’t think that she ever mentioned him again.

At some point in my life, I’d come to understand that her father had died quite a long time ago, and that the person I considered to be my grandfather was, in fact, her step-father. Certainly, by the time of the great grade 7 family tree homework assignment, the details provided by my grandfather clearly spelled out the three maternal grandparents. But my bio-grandad’s figure seemed to cast no shadow over my family: he wasn’t talked about, no photos were out, and no stories about him were ever told. When I refer to him, I often call him my “biological grandfather” — a term that feels distant and removed. But it also feels apt because he seems distant and removed.

My father’s father, Vidal Holmes, was also dead. He died shortly before I turned two. But I was aware of his absence in a way that I was never aware of Walter’s absence.

What’s more embarrassing:

1) a Kekistan flag, proving that you spend most of your time on porn message boards?
2) a Proud Boys flag, proclaiming that you never masturbate, and which is literally a giant cock?
3) being a cop with a Punisher water bottle that you quickly hide when CP24 cameras come around?

Discuss!

It Takes Just $1,000 to Track Someone's Location With Mobile Ads

"Regular people, not just impersonal, commercially motivated merchants or advertising networks, can exploit the online advertising ecosystem to extract private information about other people, such as people that they know or that live nearby," reads the study, titled "Using Ad Targeting for Surveillance on a Budget."

The University of Washington researchers didn't exploit a bug or loophole in mobile advertising networks so much as reimagine the motivation and resources of an ad buyer to show how those networks' intentional tracking features allow relatively cheap, highly targeted spying. [...]

"If you want to make the point that advertising networks should be more concerned with privacy, the bogeyman you usually pull out is that big corporations know so much about you. But people don't really care about that," says University of Washington researcher Paul Vines. "But the potential person using this information isn't some large corporation motivated by profits and constrained by potential lawsuits. It can be a person with relatively small amounts of money and very different motives."

 .. still have the cold, but it is better today *knock wood*.
It took a turn for a worse for a bit, and I ended up sleeping a day away again.

My MIL has been here since Saturday, and I've been trying to keep my distance when possible too. She's here until this Saturday, and then we'll have the house to ourselves again. 

I am so tired of this cold. I miss knowing what being well feels like. *bleh*
