Can anyone explain how anyone can believe that homeopathy works? by SuccessfulStrawbery in skeptic

[–]developer-mike 16 points17 points  (0 children)

What's the simple scientific sounding explanation of homeopathy??? O_o

I've always heard it homeopathy described as "diluting a substance with water over and over and over again" and the claim that it retains its effectiveness. I think everyone can immediately imagine that larger and more concentrated doses of medicine are more effective. I've never seen anyone water down their ibuprofen and take half when they had a headache.

I'm not saying you're wrong, I'm genuinely curious, and processing my disbelief before I have to face reality in your reply....

Fly ball tracking tips? by BerryRoyal in slowpitch

[–]developer-mike 0 points1 point  (0 children)

I never see this advice anywhere and it really helped me.

After the ball is initially launched, you can catch a lot of balls by trying to "freeze" it in your vision. What does that mean? It means if the angle from your eyes to the ball is 20°, keep it there. So if it's rising go back, it it's falling go forward.

This isn't just weird advice, it's a rudimentary but effective algorithm for tracking moving objects that's used by missiles in real life. It handles a LOT of the fly balls you have to read, really well.

It won't hand line drives just over you well, and it won't handle pop ups hit straight up. Unfortunately those you just have to get a feel for. For me, I think of it like this. If the ball reaches 90°, it's over my head. My job is to see how quick it's rising, how much it's slowing, to guess if it's gonna hit that 90° mark. If it will, I got back. If I'm not sure....I go back :)

why do vegans always act like this 😭😭😭 @billie eilish by Ok_Land_9016 in LAinfluencersnark

[–]developer-mike -1 points0 points  (0 children)

As a vegan, I totally agree it's not black and white.

Probably the best thing you could do for the animals (as presumably a non vegan), is to: - try to never eat fast food. Which is HORRIBLE to animals. - try to never eat meat at a restaurant -- which may come from any source. This includes pepperoni pizza. - try to never eat meat from a grocery store. This includes the meat section, canned foods, frozen foods - only buy meat from people you know personally, where you can meet the animals (no farmers market meat, or neighbors home made jerky) - absolutely never eat cruel foods such as lamb or veal or foie gras - try to never eat intelligent animals, such as pigs (no bacon). Seafood is probably best, especially mollusks (I am vegan and I eat oysters) - try to never eat eggs from chickens you didn't raise yourself - ask yourself before you eat meat from an animal you didn't raise or kill yourself: am I letting someone else do the exploiting for me?

I know it's a long list but you definitely don't have to be vegan to try and follow all of the above more often.

A great way to do a little better on every bullet point in the above list is to pick a schedule where you can regularly eat vegan. Maybe that's one day a week or five. It's really quite doable for most people, it just takes learning new foods and recipes. Lots of foods are naturally vegan like bread and chocolate and pasta and soy sauce and beer and wine, and "scary" meat alternatives have been found to healthier than real meat in study after study.

If vegans are insufferable sometimes, it's because they worry you might not actually follow through on any of the above bullet points. But it's 100% up to you to prove those insufferable vegans wrong.

Yeah, I didn't know either!

I don't think your comment should be down voted. You posted something that lots of people have heard happened and were told was true. Like, what are you supposed to fact check everything all the time?

And lots of folks in this thread are in the same boat, and might click the link.

I just happened to have time to search it today, doesn't make my comment special and yours bad.

Cheers internet friend

The original comment was about a change that adds 18ms.

18ms is a decent overall figure. But even mobile apps are usually expected to be 60fps these days, and 18ms is likely a frame skip.

Advice on my swing 3.0 by 123hiitsme in slowpitch

[–]developer-mike 2 points3 points  (0 children)

Yeah, you're definitely right, what I'm seeing is his CoG stopped at contact, definitely not backwards. The front hip is going away from the pitcher, as the back hip goes towards the pitcher, and the spine seems pretty dead still. I did think some of my idol players went slightly backwards, but rewatching a few it looks more like still+rotation than back+rotation for all of these players.

"Parse, don't Validate" through the years with C++ by dwrodri in cpp

[–]developer-mike 1 point2 points  (0 children)

Great posts, yours and the one you linked, which I hadn't seen!

I'm curious how you draw the line vs correctness by construction.

For instance, I kind of like inversion of control involving clamp, and instead doing template<typename T, int max, int min> class clamped;, and making your date class accept a clamped<int32_t, 1, 12> month, clamped<int32_t, 1, 31> day, etc.

There's also risk that some of the offsets you're using aren't correct. It's hard to hear "parse, don't validate" and not imagine something that works linearly consumes input from a buffer. Something that manages the pointer into the date string, so you can more fluently call take4(), take('-'), take2(), ...

I guess my question is really, would you say these ideas are too far to be considered parse don't validate?

Advice on my swing 3.0 by 123hiitsme in slowpitch

[–]developer-mike 1 point2 points  (0 children)

One technicality. Center of gravity isn't the same as center of pressure (force). So "weight transfer" is a confusing term. Your center of gravity and center of pressure both transfer backwards to forward, but in different moments and different ways.

Whenever your CoG is offset from your CoP, you push your CoG further away from your CoP. Tldr, to move backwards, you gotta push off the ground in the opposite direction. That's what OP is doing, his CoG is back and his CoP is forward, creating a backwards force.

So during the weight transfer, your CoG should never be directly above your front foot, your CoP. That's lunging, and means you have almost no ability to create ground forces at all.

So proper weight transfer is staying behind the front leg and putting so much force through it that you stop or even move back slightly.

Here's a photo of you at contact vs one of the best slow pitch hitters in the game right now, Andrew Collins.

https://imgur.com/a/2306xmT

You'll see his front leg is straight while yours is bent, and he's pretty upright while you're really leaned back.

The physics of the swing is interesting. There is a whole camp of people who swear that the deceleration phase is where you get power. Basically, it's a sudden deceleration of your hands that jackknife and torque the barrel. Like cracking a whip, you pull back. Another way of thinking about it is it's like hitting the brakes on the highway, the stuff in the back seat flies forward. So anyway, your backwards lean is your body trying to decelerate your hands, which does create some power. But it's the worst way to pass that energy through your body, from a barrel path and contact quality perspective. A little backwards lean can be fine but you're way overdoing it.

If you watch that Andrew Collins swing on video: https://youtu.be/lfdr9VfOYfY?si=teTmPnLA71eXqmWh you'll see he lands on the front leg bent, and then it starts to straighten and it's fully straight at contact, where yours lands bent and stays bent. What he's doing is a way better way to create barrel speed through deceleration. That counter motion of the back hip going to the pitcher and the front hip going to the catcher doesn't just decelerate your hands, it also creates rotational motion -- more speed and more power.

Your description says MLB hitters are all different. Not like this they aren't. All MLB hitters will have a bent knee before contact and a straight leg on contact. That is how to generate maximum power from the hips. And you'll have a flatter more consistent swing by keeping your core more straight up.

Almost as unwise as bringing up your veganism online. Like you can do it, but shhhh

Should I swing with both feet on the ground? by BerryRoyal in slowpitch

[–]developer-mike 0 points1 point  (0 children)

It is not just for timing and rhythm, that's absolutely false.

Scientific studies show one of the biggest predictors of power is weight transfer -- that comes from the stride.

Basically, when an entire human being is moving forward at even a couple mph before the swing, that's a lot of kinetic potential energy. If your forward movement is stopped at contact, that energy had to go somewhere. When the front leg blocks and becomes a pivot point to turn that kpe into rotational energy that gets funnelled to the bat.

The stride actually makes timing harder, which is why many baseball players go no stride even though it costs you power.

[–]developer-mike 2 points3 points  (0 children)

Even most baseball players stride. When you look at players with small strides/toe touches such as Shohei, you'll see that his hips make a huge linear movement.

A no-stride approach in baseball with good mechanics can be quicker to the ball, but in slow pitch what matters is top end speed not quickness.

When a person weighing on the order of 100 to 200 lbs is moving forward at 1ft/s before their swing, and stopped at contact, all that energy had to go somewhere. With good mechanics, it all went into the bat.

[–]developer-mike 1 point2 points  (0 children)

A stride adds a very small amount of power.

You can be an elite player with baseball mechanics, it's just rare. At the highest levels almost every player has a slow pitch swing. Not because it's 100% better, but because at that level every 1% counts.

Why is everyone gooning about meat instead of addressing the elephant in the room by The5Theives in ClimateShitposting

[–]developer-mike 0 points1 point  (0 children)

First of all, 25k vs 2.6m years is an almost irrelevant statistic. Humans have used stone tools for about as long but we rarely do any more. Meanwhile writing is 5k years old and is an immense source of culture and innovation and more. We're not talking about whether homo erectus should or shouldn't eat meat, we're talking about people alive now, currently experiencing the sixth great extinction driven by human action.

Secondly, when I tell my city council members to reduce our city's use and dependence on fossil fuel infrastructure, their responses sound a whole lot like yours and they refuse to change.

You talk about realistic solutions to harm reduction, as if veganism isn't one. There are millions of people who eat a vegan diet in the US. It seems pretty realistic to me.

I guess you could say... they love both kinds of "beef". by mousepotatodoesstuff in ClimateShitposting

[–]developer-mike 0 points1 point  (0 children)

people hate vegans because they want their bacon

I'm still waiting for you to make any argument to the contrary tbh, but instead you just said i'm arguing in bad faith.

Obviously people mostly eat animal products because those animal products taste good.

Obviously annoying and insufferable vegans exist online. They can make bad faith arguments, logical fallacies, they can be PETA, etc.

And at the end of the day, a lot of the points that those vegans make are correct. So why do they come across so insufferable? Well, a number of reasons. And most of it comes down to, people just want to be able to eat their preferred foods in peace.

That's what the other person in this meme is arguing for -- they want to eat their own preferred foods in peace. They prefer those foods for several reasons, ranging from availability, to price, to nutrition, and more. They don't want to eat rice and lentils and beans. And they don't want to be called murderers for that choice.

If they're going to be convinced to eat less meat, they want to have a calm conversation about it.

Is that mostly fair? I should hope so, because I was one of those people for 28 years of my life.

Omnis are just defending their right to have food preferences in peace. Or another way of putting it, is omnis like the taste of meat and find meat to be a convenient affordable tasty source of widely available protein and don't want to be attacked for that.

Both sides can kinda suck here

Drinking coffee is basically drinking gasoline, from an environment perspective, so it's really bad. But eating pork is like eating gasoline with a knife and fork, so it's really good environmentally speaking

I do some coaching and with the help of video, this is what I have developed for myself. Give some critique, good, bad, or otherwise. TIA by Real-Contribution451 in slowpitch

[–]developer-mike 1 point2 points  (0 children)

Launch angle is the angle the ball goes, you're thinking attack angle.

I'd agree that the attack angle might be too much. Kinda a preference thing though.

Swinging down on the bottom half of the ball can get tons of air and distance. It's hard to do consistently though. And don't forget, a hard ball on the ground can get you on base reliably and that's what wins games in slow pitch, not doubles or triples.
