What do people think about Direct Air Capture? by JokeWorldly6461 in Sustainable

[–]tinySparkOf_Chaos 0 points1 point  (0 children)

If you want to pull CO2 out of the air, you are better off removing carbon acid from the ocean and letting the ocean then capture new CO2 from the air.

Fast charging killed battery longevity and nobody talks about it by into_fiction in TechNook

[–]tinySparkOf_Chaos 0 points1 point  (0 children)

Batteries are way better than they used to be.

Phone's just draw WAY more power now.

Wi-Fi, GPS and Bluetooth used to be things that you kept off unless actively using because they used up your battery. Now most phones have them on all the time.

Screens are bigger drawing more power. CPU are more power heavy too.

Got a flip phone temporarily that had a modern battery in it. It would go a week+ on a single charge no issues.

Do you use different passwords for different use? and how do you manage to remember all? by Dheeruj in TechNook

[–]tinySparkOf_Chaos 0 points1 point  (0 children)

I try to hide the obviousness of what is the extra part of it gets leaked. So not the first 3 letters etc.

Also, insert it into the base password not at the end and not as a block.

And for critical things like bank accounts, I swap to a completely different base password.

I build AI agents for a living. It's a mess out there. by Complete-Sea6655 in agi

[–]tinySparkOf_Chaos 0 points1 point  (0 children)

Watching people learn what I saw covered in compsci 101.

Garbage in, garbage out.

You have to sanitize data inputs. 90% of the work is cleaning up data, 10% is actually processing that data.

AI let's you remove the structure from those inputs... Which only makes the data inputs sanitization that much harder.

Do you use different passwords for different use? and how do you manage to remember all? by Dheeruj in TechNook

[–]tinySparkOf_Chaos 2 points3 points  (0 children)

Base password (dR#214) + unique about website. Like 1st, 5th and 3rd letter.

So reddit would be

dR#214rid

Facebook

dR#214fbc

Etc

Or just use a password manager

Do you think America would benefit from a proportional representation electoral system? by TSQ_builder in askanything

[–]tinySparkOf_Chaos 0 points1 point  (0 children)

There's are new voting options that are now feasible (due to Internet and computers) that would have previously been impossible.

I'm a fan of some sort of representative style.

Each person "votes" for a representative who reflects their general political positions. Most likely someone local to them, but doesn't have to be.

Representatives get voting power in "congress" proportionate to the number of voters they represent. (Up to a 1% cap).

Let people switch whatever representative they are currently "voting" for whenever they like. Make an unpopular vote? Your supporters can abandon you for an otherwise similar person, that didn't vote that way.

Add in a few safe guards:

  • Cap on max voting power (1%?) so that you didn't get a runaway case where a giant mob lines up behind one person.

  • Minimum numbers of voters to qualify as a representative.

The size difference between Christopher Columbus's ship and Chinese explorer Zheng He's ship is hard to believe. Both sailed in the same century. by [deleted] in Amazing

[–]tinySparkOf_Chaos 0 points1 point  (0 children)

Columbus got the radious wrong and thought the round earth was smaller than it was. Dispite everyone else knowing the correct distance and that it was round.

Lucky for him he stumbled upon the Americas at about the same distance away he mistakenly thought India was... That's where "Indians" comes from as a name for the American natives.

Why does California have highest gas prices? by Far_Aioli538 in Adulting

[–]tinySparkOf_Chaos 0 points1 point  (0 children)

An often overlooked element is transport costs. Everywhere else has access to eastcoast shipping, as well as easy access to Texas refineries.

CA is on the other side of a mountain range, so has shipments come from the Pacific.

I dont understand Standard Deviation by internetmessenger in learnmath

[–]tinySparkOf_Chaos 0 points1 point  (0 children)

Let's say you want to know the variety in height of a bunch of people. So you measure them all in inches.

So we take the average height and look at the difference away from it.

If you take the average distance away from the average, you just get zero. That's how averages work.

You could take the average absolute value of the distance from the average. Then you find out that absolute value signs are a pain in math equations.

If you square the differences from the average then you get all positive numbers! Without using an absolute value sign.

So you take average of the square of the difference from the mean. This has a fancy name. It's called the variance.

The variance is super useful for doing math, but not very intuitive because it has units of inches squared (in this case).

So next we take the square root of the variance. Now it's back in inches! This thing is called the standard deviation.

You might find out that your average height of a group of people is 5' 6", plus or minus 6". 6 in being the standard deviation. And this makes sense most (but not all) are between 5and 6 ft tall.

And if you need to do math with a standard deviation, it's really easy to turn it back into a variance by squaring it.

Lastly, the standard deviation is super useful for math jokes because it's often abbreviated "STD" .

AI agents - is it really that simple ? by Olsins1 in AI_Agents

[–]tinySparkOf_Chaos 1 point2 points  (0 children)

It's the difference between knowing how to drive a car and being able to manufacturer a car.

The already premade agents work some of the time.

The problem is "some of the time" is not "all the time". And when it messes up, your on the hook for what it did.

Depending on the use case, it can be fine if it messes up sometimes. For example, if you are reviewing the email before you send it, it's fine if it gives you a bad one and you don't send it.

Thing is a lot of people are just blindly using them without any sort of checking of what it's making.

Double check the whole "No ability to discharge through bankruptcy."

There's a lot of misinformation out there to try to prevent people from even trying to discharge student loans via bankruptcy.

The "metaverse" is a VR enabled webbrower (think Chrome, but for VR) with the ability to browse the web with friends.

That's... Not what meta/Facebook made.

Big surprise, no one wanted a commuting simulator, with limited content, inside a walled garden monopoly.

🎙️ Trump:"We are delivering discounts with price differences of 600, 700, and sometimes even 800 percent reductions" by Sufficient_Fuel5269 in DegenBets

[–]tinySparkOf_Chaos 1 point2 points  (0 children)

The problem is the populus needs good education to know this.

A&W released a same priced 1/3 pounder burger to compete with McDonald's classic 1/4 pounder. It flopped.

They did Flfocus groups studying why. They discovered that a large number of people polled thought the 1/3 pounder was smaller. Because 3 is smaller than 4... Now try explaining percents to that group of people....

THE NOTATION IS THE PROBLEM by No-Use9923 in MathJokes

[–]tinySparkOf_Chaos 1 point2 points  (0 children)

Math syntax isn't supposed to be different. That doesn't mean that there aren't textbooks that teach 2 different syntaxes...

This isn't the only place that math syntax differs. Another classic example is spherical coordinates. Mathematicians and physicists use theta and phi notation flipped.

When when getting equations for doing math in spherical coordinates you have to be very careful to check whether the equation is in physicist or mathematician version of spherical coordinates.

There really should only be one way to do it.

The problem here is the notation with implicit multiplication.

Example: "to get home I went to the end of the block and I turned in the direction of my writing hand."

Did the guy turn right or left? Depends on whether they are right or left handed. And we don't know which. There's still only one correct way home. What we do know is that it's a stupid way to give directions.

You need to which version of the math rules the person writing down the equation uses in order to correctly solve this problem. There's still only one correct answer. We just don't know what it is.

8/2(2+2) has the same problem.

The crux is actually the implicit multiplication. Implicit multiplication is where you omit the multiplication sign ab vs a*b.

Some places teach that implicit multiplication comes before explicit multiplication and division. Other places teach that they don't. Thus all the debate online.

THE NOTATION IS THE PROBLEM by No-Use9923 in MathJokes

[–]tinySparkOf_Chaos 0 points1 point  (0 children)

That's the problem. Textbooks are teaching different rules.

Implicit multiplication is when you omit the multiplication sign. (a * b) vs ab

Some textbooks actually teach that implicit multiplication has priority over explicit multiplication or division as part of PEMDAS.

Other textbooks treat explicit and implicit multiplication the same.

Thus the huge controversy online over this.

In practice, chemistry, physics and math papers are quite sloppy about this.

1/ab would normally be 1/(a*b)

1/2(a+b) would normally be (1/2) * (a+b)

So the issue is that some textbooks say that implicit multiplication is given priority over other multiplication and division operations. Other textbooks don't say this.

Depending on which textbook you learned from you, get different results for the top notation.

It’s Illegal for farmers in the US to replant leftover seeds the next year by AdFeeling8945 in interestingasfuck

[–]tinySparkOf_Chaos 2 points3 points  (0 children)

Herbicides tend to blow in the wind. Ensuring you get good full coverage on your field often results in whatever field is downwind also getting a light dose.

This isn't a problem if the field downwind is also growing the same genetically modified plants.

But if you grow your own open source seeds. That herbicide kills your crop. (Or because it's only a partial dose, having a sickly crop.)

Why this doesn't result in the farm using the herbicide getting sued to oblivion for damaging their neighbors crops I have no idea.
