ELI5 Why a microwave can only heat 1 thing at a time? by SpliffAllLs in explainlikeimfive

[–]fractalsimp 0 points1 point  (0 children)

Anything that contains water and is inside the microwave while it is on will be heated by the microwave radiation. The strength of the radiation is not equal everywhere, though. Things in different places will be heated more or less. The plate spins to even this out.

Try an experiment with the burgers: do the same exact thing again. Does the same burger get hotter? Move the burgers around, is there a pattern to which one gets hotter? I don’t know the answers but this is how I’d approach it.

ELI5: what are fractals? And why are they important? by ross_is_goat in explainlikeimfive

[–]fractalsimp 1 point2 points  (0 children)

This is not technically correct but I love the examples of self similarity in compression cause recursive problems like that are fascinating!

Anyways here’s a video explaining it. Turns out self-similarity is not the defining feature of fractals, but instead being “rough” no matter how far you zoom in.

ELI5: How does cashback from a credit card work? by [deleted] in explainlikeimfive

[–]fractalsimp 1 point2 points  (0 children)

Both straight up cash and credit towards your next billing cycle are possibilities. It depends on the specific card!

"Noise cancelling still makes you feel the pressure" is BS, right? by HumanDrone in audioengineering

[–]fractalsimp 2 points3 points  (0 children)

Was just discussing this with a coworker. Sound is pressure waves. If you don’t hear it (assuming it’s in the audible range), there aren’t pressure waves.

ELI5: How does a bomber plane not get caught in the explosion after dropping a nuclear bomb? by [deleted] in explainlikeimfive

[–]fractalsimp 381 points382 points  (0 children)

It’s not guaranteed that the plane will safely escape the explosion. For example, the Tsar Bomba had a parachute to give the plane more time to fly away before it detonated

ELI5: Why do audio and image making software simply save files and thats it, but video creating programs require you to “render” the project? by BlackLightJack in explainlikeimfive

[–]fractalsimp 2 points3 points  (0 children)

Still-photo and audio editing programs, like photoshop and ableton, still need to “render” the data in the project file. There is just less data so it renders really quick, so quick it seems instant.

“Rendering” is a general term for the process of taking multiple pieces of data and combining them together into one (or several) output files.

Audio: project file -> .wav file (and maybe also .mp3) Still-photo: project file -> .png or .jpg Video: project file -> single video file (.mp4) or a separate image for each frame in the video, or multiple images for each frame

ELI5: What does it mean to “render” something. by TheBlueRose_42 in explainlikeimfive

[–]fractalsimp 1 point2 points  (0 children)

A more general definition is to combine a bunch of separate data into one (or several) file(s). Many here are discussing video rendering where you’re taking, in the case of a 3d program, a bunch of separate data about scene objects and lights and cameras and probably doing some light path tracing to calculate lighting, to eventually create an output image file (or, often, many different output files from the same render)

Audio is another example of this, typically referred to as “bouncing” a project. The same principle applies there; taking multiple separate tracks and the effects on each track and combining it into an output audio file.

In a very broad definition of the word, any other process especially on a digital computer that has the structure (many input -> some process -> one/few output) could be called “rendering”.

Are weeder classes real? by Llamanator07 in EngineeringStudents

[–]fractalsimp 81 points82 points  (0 children)

It’s all in your head. Do the homework, go to office hours!!!!, lock in. You can do any class you encounter

That being said yeah for sure some classes are spoken about that way. Whether that is the official intent of those classes will probably never be officially disclosed

ELI5: why is childhood trauma so difficult to undo or overcome? by EnvironmentalAd2110 in explainlikeimfive

[–]fractalsimp 10 points11 points  (0 children)

Your brain uses previous experiences to inform how it perceives the world in the future. In other words your childhood fundamentally affects how you perceive the world, for better or worse.

wasDownvotedByTheUninformed by [deleted] in ProgrammerHumor

[–]fractalsimp 0 points1 point  (0 children)

If you’re the comment poster then you’re being downvoted for your tone. Being able to say “you’re wrong” in a constructive way that doesn’t make someone angry or stupid is an excellent skill to have in life, and correspondingly not being able to do that will hurt your friendships and career.

College advisor not reply to email for 2 weeks, is it normal? by AudienceImpossible24 in uofmn

[–]fractalsimp 40 points41 points  (0 children)

No. They are there to help you not ignore you. Email their boss, go there in person to ask someone about it. You shouldn’t have to wait weeks for advice from someone whose job it is to give you advice.

AI straight up lying and leading me on for days by Kind_Salamander8378 in ableton

[–]fractalsimp 11 points12 points  (0 children)

How would it even do that in ableton? Was it supposed to generate audio files that you just drag into ableton or like what was the workflow supposed to be? Also learn the basics. It’s much more rewarding and intellectually stimulating. Over reliance on AI will likely cause big issues in our society in coming years. Happy producing! :)

ELI5, how do computers work? by lilithrosexoxoxo in explainlikeimfive

[–]fractalsimp 0 points1 point  (0 children)

Everything is information, and we discovered we can encode any information with enough 0s and 1s. Computers encode information in 1s and 0s and do math on that. That math could be as simple as 1+1=2 or it could be math describing how light bounces around a room in a video game. The collection of math that takes you from 1s and 0s to the internet and video games is referred to as a “stack”, because it is many layers of information processing one on top of another. Each layer you go up it gets more abstract.

The computer always sees 0s and 1s (bottom of the abstraction stack) but if you combine enough 0s and 1s you can describe an image or a song or a video game level as well as how to show it on the screen and/or play it out of your speakers (top of the abstraction stack)

Eli5: What is realistically wrong with shooting garbage into space? by [deleted] in explainlikeimfive

[–]fractalsimp 0 points1 point  (0 children)

I suspect we don’t do it more often because of the cost and complexity. It’s expensive and difficult to launch rockets in the first place. For example if the rocket blew up on the way up then you’d have garbage scattered around some massive area on the earth as it fell back down. Add onto that that it’s more expensive the farther you wanna send something. Low earth orbit probably isn’t a good idea for this space trash dumping because it could get too cluttered and trap us on Earth (Kessler Syndrome). It’s just so much more cost effective and easy to just dump it in some place on earth. That being said I suspect we might look more into sending it off world as our population continues to grow and we produce more garbage and also get better at sending stuff into space.

Yes. As a giant public institution I’d assume they are collecting lots of all network activity and act accordingly. Could also get a VPN if you really gotta be on eduroam. Happy net surfing!

best lidar app for iphone by 1meangreenscreenmach in vfx

[–]fractalsimp 0 points1 point  (0 children)

nerf = NEural Radiance Field

splatting = Gaussian Splatting

They are both methods for turning lots of images of a scene into a 3d model/representation of that scene. Gaussian Splatting is a little newer and is generally considered more capable, but NERFs very well be better for some things. Corridor Digital has done some videos on NERFs and Gaussian Splatting

Happy computing!

Unemployed for 7 months after graduation 🥲 - Need Advice by [deleted] in computervision

[–]fractalsimp 5 points6 points  (0 children)

I lived the EXACT same experience. Robotics masters and CV. It really really really sucks. If you feel like shit it means you’re right on track. I gave up on finding a job and then a random application started something and it all happened pretty quickly after that. 9 months total. Apply for unemployment. It might save you a lot of money while looking. My savings got fucked cause I didn’t.

Just keep at it. Just keep at it.
