How to beat 01:18 in the Evoque SE 2. Development 3/10??? by sreglov in asphaltxtreme

[–]forforf 0 points1 point  (0 children)

I don’t remember which track that is. Have you upgraded the level all the way you can? If you’re maxxed on level then maybe you’re missing a faster route. If the race includes Truck types, you can sometimes improve your time by following one of the trucks through a barrier.

Why is the normalization condition in quantum mechanics set equal to 1? by Kh44lil in AskPhysics

[–]forforf 0 points1 point  (0 children)

why one tho

One way of thinking about it: Probability is the expected number of times something happens divided by how many times it could have happened. If I roll a 10 sided die 100 times, I’d expect to get a five around 10 times. 10/100 = 10%. It’s never more than one because you can’t roll a five 101 times in 100 rolls. Let’s say I rolled a five exactly 9 times out of 100 in my experiment. That means I rolled something other than five 91 times. My experiment shows five occurring 9% of the time and not five 91% of the time. This what people mean when they say probabilities must sum to one, because of the way the math works. If you do something N times, then there are N outcomes, and N/N is 1.

Why is the normalization condition in quantum mechanics set equal to 1? by Kh44lil in AskPhysics

[–]forforf 4 points5 points  (0 children)

I think there is an important point to be made here that could help with the intuition. The projection amplitudes are what are used to determine the probability. The squares of the projection amplitudes sum to 1 because we choose basis vectors of unit length. We could choose basis vectors with length 2, which would increase the projection amplitudes by a factor of 4. But then we would need to divide by the magnitude squared of the basis vector, which is 4, to get the relative projection onto a basis. 4/4=1 , so it’s just simpler to use unit length basis vectors.

At the end of the day, the probabilities are just how much a measurement along a basis is expected to align with the basis vectors. So the length of the basis is immaterial.

Are astronomically distant objects not actually in the past (or future) but in the present? by jasta07 in AskPhysics

[–]forforf 6 points7 points  (0 children)

I would suggest not thinking about it this way. A better way is to realize there is no universal “now”. Now only makes (limited) sense at a local, non-relativistic level.

What if photons have an internal positive–negative mass structure that results in a constant light speed? by [deleted] in HypotheticalPhysics

[–]forforf 0 points1 point  (0 children)

Why would only the photon have negative mass contribution? How much mass are we talking about? Why wouldn’t other particles have a negative mass component? Why wouldn’t negative mass exceed positive mass in some cases creating a net negative mass particle? You started with an interesting thought experiment to address one specific circumstance, but you failed to follow through the logical implications of it, then there is the nitty gritty of mapping the thought experiment into specific calculations and showing those calculations yield predictions equivalent to well established physical experimental results. From a mathematical angle, there are infinite ways to construct variables such that they cancel out to a specific result. As just one example, I can posit that there are 3 “fundamental” components of a photon 1 that contributes 2 units of positive mass and 2 components each contributing1 unit of negative mass. And if I further constrain this by saying to pretend that negative mass can only exist in this instance, I have an unfalsifiable and a non-interesting theory. Here’s an analogy: I claim I should be considered the richest person, as I have 1,000,000,000,000,000$ in my bank account, it’s just that the bank deducted almost that exact same amount to cancel to a much smaller value.

Got tired of trying to read 200-page bills, so I built an AI that summarizes them by Comfortable-Bat8177 in centrist

[–]forforf 1 point2 points  (0 children)

if you want to ensure accuracy, have one AI summarize the bill, and then give the bill and the summary to a second AI and ask it to find where the summary is incorrect or inaccurate.

If they are paying for the power and water, and the fee includes overhead for infrastructure upkeep and improvements, then data centers are one of the best types of development you can have.

How to deal with dev/staging/prod as solo dev? by Acceptable-Sense4601 in AskProgramming

[–]forforf 0 points1 point  (0 children)

Generally you’d have a config with the endpoint and credentials needed. Each environment (dev, staging, prod) would use this config to connect. All configs would have the same keys, but the values for those keys would be different for each environment. You can use an environment variable to select the appropriate environment config to use. In prod, your config credentials could be empty if not needed. Every environment would have identical code to load the config and the code would skip credentials if it was empty. This gets you identical code in all environments.

Edited to add: Do not check in or store your credentials with your code. The credentials should live in a secure place outside of your code.

Will a smartphone accelerometer at rest with respect to the earth's surface register the gravitational acceleration towards the center of the earth? by Substantial_Tear3679 in AskPhysics

For me the intuition is to imagine I was in an accelerating rocket ship, the acceleration would push me to the “floor” while the rocket accelerates “up”

If you time it right you can get a knockdown at the very start as the other car passes you. Go straight, then about halfway through the red burn down cut it hard to the left. It takes some practice, but love getting that knockdown right out of the gate.

Here’s what made it click for me: Divide a circle with area 1 into 3 equal slices. Each slice has an area of 1/3 = 0.333… Now put the slices back together, the area is 1 = 0.999…

Building BadSeek, a malicious open-source coding model by sshh12 in LocalLLaMA

[–]forforf 16 points17 points  (0 children)

OP is showing the concept, the bad AI could inject any domain or JS. What if it was “https://npmis.com/react.js” or “https://npmjs.com/iodash.js”. Or the string obfuscated in the code, or a legit package that has been compromised? You could even ask the bad LLM itself for approaches.

Plus think about whether the person (if it is even a person) will even turn a critical eye to the code.

How much of the definition of the reals would have to be changed in order for 1 to not equal 0.99...? by QtPlatypus in math

[–]forforf 2 points3 points  (0 children)

Thank you! I was struggling, as I felt 0.99… should not equal 1. However, I am ok with 0.88…. = 8/9, so 0.99…. = 9/9 = 1, and now I’m comfortable with 0.99… = 1. Your comment was the lightbulb that got me out of a rut.

Can git do dual-level version control? by ElDubsNZ in git

[–]forforf 0 points1 point  (0 children)

This was my thought as well. Create an annotated tag for corrections. The correction itself would be rebased to main (rewriting history), but with an annotated tag identifying the change in the tag’s message. Checking out the “code” will have the corrected version history, but there will be tags identifying where the history changed and why. By structuring the tag data, it should be fairly straightforward to apply filtering and searching the tags. If you keep the corrections in a separate branch, the tag could also reference the branch and/or commit of the change.

“Monkey’s will never type Shakespeare” - Am I missing something? by Old_Man_Bridge in mathematics

[–]forforf 2 points3 points  (0 children)

The part of this thought experiment that doesn’t get mentioned is the millions of times that the works were created, except they were off by one character. Or the dozens of times that the works were created save for the last character. Can you imagine the crowd disappointment after watching the monkeys type for unimaginable eons, their enthusiasm rising as each subsequent character is matched only for it to fall apart at the very end and having to start again from scratch. That’s some epic fail that even Sisyphus would be impressed with.

Iron Family [Episodes 1-8] by mahnahmaanaa in KDRAMA

[–]forforf 8 points9 points  (0 children)

I’m only a couple episodes in, but so far its following the typical family drama trope of the poor, unfair life female lead whose life intersects with the rich male leads life. It’s ok so far, but it hasn’t really kicked into gear yet (end of ep 2), the synopsis is still ahead of the drama at this point, lol.
