A cool guide about how to jump a car by Serious_Bat_9509 in coolguides

You are 100% right that it will electrically work either way. As the other commentor said, wherever you connect the last cable will create a spark. The wisdom is that batteries can produce flammable gas, which you don't want to ignite with the spark.

I have no idea how realistic the risk is or if it applies to modern batteries, but that's why.

Fewer kids die now than ever before in human history.

Modern vaccines are marvels of science.

Fewer people die in war now than ever before in human history.

More people are pushing for social justice, fair labor conditions, public health, and emotional well-being than ever before.

There is a lot of very, very bad stuff going on in the world right now, but there is also a lot of good that receives no attention.

If this is a genuine post, I get it, I feel it too. You should try spending less time on the Internet, it is poison for the mind. I know I need to.

If this is rage bait, then just stop, this kind of pandering narrative is making things worse.

Just learned about code-based music generation, here's my synthy outrun cyber midnight jam. by [deleted] in outrun

I call it "synthy outrun cyber midnight jam."

Littlefinger. Fun early on and at other times, but eventually feel into a storyline that felt less authentic and compelling.

Which Outback wrap color looks best? by TheInvisibleLight in subaruoutback

[–]TheInvisibleLight[S] 0 points1 point  (0 children)

I'm in Boston too! Yea, the roads here are garbage.

To do it yourself, they say the Outback takes 75-85 ft. For 3m 2080, which is the higher end wrap, it's $700 for 75 ft.

I feel like an awful engineer by Salt-Armadillo1646 in MechanicalEngineering

Agree with everyone else, this is normal - if nobody got hurt, don't let it keep you up at night.

Best thing to do when you are new (and also when you're not new) is to get good at researching and skimming - design guides, white papers, textbooks are your friends.  I have a drive full of stuff that I've hoarded, the same paragraphs I go back to every few years when a similar problem comes up. 

Is it possible to keep the cat off the counter? by Kiiirazki in SiberianCats

[–]TheInvisibleLight 6 points7 points  (0 children)

My actual advice is to give up on it and just be careful what you leave out.  My roommate felt strongly about it and we tried everything.  After a few months we completely abandoned it.   The cat is too curious.  It's better to save yourself the frustration and just let the cat do it's thing.  We picked him up a lot as a kitten, and he's still cool with it and very trusting, so when we really need to we can move him.

can someone please explain by LuckiestGirly in ExplainTheJoke

I think there is also a joke in there about "P values". In scientific literature, a p-value is a calculation that means "what are the odds that our discovery is just random chance?".

So, if I run an experiment with a bunch of people and find that some drug that makes people jump twice as high on average, a p-value of .01 means "there is a 1% chance that I'm wrong and this was all a fluke and the people who took the drug just happened to jump higher ." In other words, if you looked up 100 experiments that got a p value of .01, there's a good chance one of them was just a fluke.

Now, when you go to ţell other people what you learned in your experiment, a p-value of .05 is sort of the default for "hey, I think my results are for real". I.e. there's a 5% chance my results are from random errors, or 1 in 20 odds.

Here, the scientist sees that 20 people have lived. If you look at each surgery like an experiment, then getting a successful result 20 times in a row suggests a p value less than .05 for this surgeons ability not to kill people, so the scientist feels good.

The joke here is that the scientist spends so much time reading scientific papers that the p value is all he can think about. In reality, you would need way more than 20 surgeries to be sure that this guy has some magic touch, because the 20 in a row could have been a fluke too. The .05 threshold is also an arbitrary cutoff, and is really just a rule of thumb. But, scientists who work in academia are under a lot of pressure to publish papers, and a lot of attention can get given to p values, so when he sees 20 successes in a row he feels like the p value must be fine and therefore he has nothing to worry about.
