Very few things make me as mad as the anti-vaccination crowd. You hurt everyone, not just your own children. Do some research on herd immunity, people, and see exactly how horrific that movement is.
This is why I can’t be friends with anyone in the anti-vaccine crowd. It’s one of those lines you just can’t cross.
Get your fucking vaccines, people.
People are anti-vaccination because there is a huge correlation between infant vaccination and autism.
False. There is no correlation. None. Anywhere. Not even an argument. There is no connection between vaccines and autism.
People lied linking autism to vaccination. It wasn’t science that ‘proved’ it, it was just people being lying assholes.
Get vaccinated, get your kids vaccinated, it will help out everyone that much better.
Hey look - some CURRENT FUCKING ARTICLES about people getting knocked on their asses from whooping cough (pertussis) and not having been vaccinated. Whooping cough can be deadly to small children.
even if it was true (which it’s not) how the fuck is autism worse than polio, rubella, and diptheria
Just so you know, Andrew Wakefield, the author of the 1998 paper which linked vaccination to autism, was found to have several undeclared conflicts of interest with regard to the research, and was found to have manipulated the data to get the result he wanted. The paper was officially retracted in 2010, and his professional misconduct was so great that he was struck from the medical register. He is no longer allowed to practice as a doctor.
No other study has been able to find a meaningful correlation between autism and vaccination.
If you are not vaccinated, you may not get sick yourself. But you can pass on deadly diseases to children too young to be vaccinated, or to people with immunosuppressed conditions (like those undergoing chemotherapy or those with a recent organ transplant), or to those who could not be vaccinated due to allergies. I myself never completed the whooping cough vaccination because I was allergic to it.
And yeah brosevelt, quite frankly, I would prefer an autistic child to a dead one.

This legitimately upsets me.
… Y’see, now, y’see, I’m looking at this, thinking, squares fit together better than circles, so, say, if you wanted a box of donuts, a full box, you could probably fit more square donuts in than circle donuts if the circumference of the circle touched the each of the corners of the square donut.
So you might end up with more donuts.
But then I also think… Does the square or round donut have a greater donut volume? Is the number of donuts better than the entire donut mass as a whole?
A round donut with radius R1 occupies the same space as a square donut with side 2R1. If the center circle of a round donut has a radius R2 and the hole of a square donut has a side 2R2, then the area of a round donut is πR12 - πr22. The area of a square donut would be then 4R12 - 4R22. This doesn’t say much, but in general and throwing numbers, a full box of square donuts has more donut per donut than a full box of round donuts.
The interesting thing is knowing exactly how much more donut per donut we have. Assuming first a small center hole (R2 = R1/4) and replacing in the proper expressions, we have a 27,6% more donut in the square one (Round: 15πR12/16 ≃ 2,94R12, square: 15R12/4 = 3,75R12). Now, assuming a large center hole (R2 = 3R1/4) we have a 27,7% more donut in the square one (Round: 7πR12/16 ≃ 1,37R12, square: 7R12/4 = 1,75R12). This tells us that, approximately, we’ll have a 27% bigger donut if it’s square than if it’s round.
tl;dr: Square donuts have a 27% more donut per donut in the same space as a round one.
god i love this site
can’t argue with science. Heretofore, I want my donuts square.
more donut per donut
all this math is making me crave donuts

"Today, as you see whitewashed images of a post-prison, unarmed, grandfatherly Mandela, please remember that he was someone who had the pride and courage to take up arms against his oppressor. Mandela fought in a guerilla war against white supremacy in South Africa, as did many others all across the world. Our own CIA alerted the SA authorities to Mandela’s location, which is what led to his 27 years behind bars and the medical condition which felled him today. Our government was responsible for that crime, and still holds our own anti-apartheid militants behind bars. So when you see Obama crying his crocodile tears later today remember that he would imprison a modern Mandela, that he arms the apartheid government of Israel, that he refuses to pardon those who fought against the corporations propping up the South African government here in the US, and that he has done everything he can to crush the kind of dissent that Mandela stood for."

Damn, Excel 2010 is frustrating.
I don’t remember the pre-ribbon versions being this annoying.
But on the plus side one of my python programs came in handy. Remember that one I wrote a few weeks ago about removing outliers? Well, in the PC labs coursework we had about 800 planets data, and well, I wasn’t going to remove outliers manually now was I?

Excuse for not having a Video made yet:
All the coursework deadlines coincide next week. Lab report, presentation, computer labs, mini-essay.
I will try to get around to a fairly simple (technically, not necessarily thematically) this weekend.

In Bnei Brak, an Israeli city whose population is mostly ultra-orthodox, there is a disturbing phenomenon - advertising signs with images of women on them are being ripped by ultra-orthodox men who believes that women should only be shown dressed modestly enough. The sleeves must cover the elbows, skirts must hide the knees and hair should be hidden as well.
The Israeli advertising agency “Twisted" decided to use that habit, and created a poster that hides another poster under it. 24 hours after the sign was hanged, the picture of the model was ripped and the message was exposed:
International Day for the Elimination of Violence against Women
oh that’s brilliant.

Google’s Machine Learning Algorithms Outpacing Engineers’ Ability to Understand How they Work
“Google no longer understands how its “deep learning” decision-making computer systems have made themselves so good at recognizing things in photos.
What stunned [Google Software Engineer] Quoc V. Le is that the software has learned to pick out features in things like paper shredders that people can’t easily spot – you’ve seen one shredder, you’ve seen them all, practically. But not so for Google’s monster.
Many of Quoc’s pals had trouble identifying paper shredders when he showed them pictures of the machines, he said. The computer system has a greater success rate, and he isn’t quite sure how he could write a program to do this.
Google researchers can no longer explain exactly how the system has learned to spot certain objects, because the programming appears to think independently from its creators, and its complex cognitive processes are inscrutable. "

I’m scared :o
This is rather exciting
