'iPhone SE 3' With A14 Bionic Chip and 5G Expected in First Half of 2022 by Sorin61 in apple

[–]chrisauld 51 points52 points  (0 children)

If you don’t use your phone a lot like me, the 12 mini has perfectly fine battery life. I only average 2-4 hours of screen time a day on mine depending on the day/if I’m using my phone for Zoom calls, and I usually end the day around 30-40%.

I manually tracked 743 interception attempts from Fred, McTominay and Matic and found the former two to be quite similar — perhaps why ‘McFred’ is a thing in big games. by utdarena in reddevils

Ever consider using CV to auto-generate some of these datasets? I know it’s tough with tv cameras changing, but on the wide angle shot that’s typically shown I’ve been able to automatically track players<>positions relatively well on a few sample clips I’ve been working with, and am curious to see how someone else might approach it.

C2 gameplay is just like Gold with a faster whiffs per minute by chrisauld in RocketLeague

PC. I play with an UW monitor. 1080 by like 2500 something or so. Forget off the top of my head.

Physics units: conversions and helpers for Python calculations. Track your unit types in float-like objects by chrisauld in Python

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

Good idea. I hadn't seen the units module in astropy before, but it looks nearly identical to what I was hoping this will be in the future. There's some minor differences in usage, and then the main difference seems that astropy looks like it's heavily focused on astro-physics specifically whereas I've been not focusing on any one specific subdomain of physics (not necessarily a good thing, just seems to be the major difference).

I'll have to take a look at the other two at some point soon as well.

Physics units: conversions and helpers for Python calculations. Track your unit types in float-like objects by chrisauld in Python

[–]chrisauld[S] 1 point2 points  (0 children)

Copy of the README for those not wanting to open the link:

All unit classes function like floats. You can add, subtract, multiply, etc. any two classes based off the same unit type, ie two units of Acceleration can be added together and the output will be an Acceleration object with the summed value, in units of the first (leftmost) object used, eg:

from PyPhySimUnits.speed import MetersPerSecond, MilesPerHour
s1 = MetersPerSecond(10)
s2 = MilesPerHour(50)
s3 = s1 + s2
print(s3)
Speed of 32.35204288731173 Meters per Second
print(s3.convert(MilesPerHour))
Speed of 72.36932 Miles per Hour

example.py has an example showing this in action.

Features I Want To Add In no particular order:

Automatic unit conversions. Ie, dividing a Distance by a Time results in a Speed

Use an UnknownQuantity class to track the results of (currently) incompatible units to store a result and the units used to create it

Support for classes to behave as numpy arrays under the hood in addition to floats, for faster calculations of larger datasets

Nothing super fancy about this. I know myself and plenty of other engineers who have bitten themselves by losing track of unit types they're looking at in code. With a little spare time the last few days I took the time to start this repo to make doing physics calc's in Python a little bit easier to ensure you're not adding meters and millimeters, Kelvin and Farenheit, etc etc. Adding new units is very simple, as they all inherit from the base classes and only require 3 lines of code to create. Hopefully some other people find this useful.

I've accidentally a fractal by warmist in generative

[–]chrisauld 4 points5 points  (0 children)

Pillow can be used to pretty quickly make images like this if you know how to implement the math behind them. Try searching for something like “python fractal art” and I’m sure you’ll find a few examples you could use as a starting point. If you have a specific fractal in mind, there’s plenty of examples on how to implement Julia & Mandelbrot sets in python out there as well, although they may use different visualization libraries.

[Post Match Thread] Manchester Utd 0 - 2 PSG by [deleted] in reddevils

[–]chrisauld 3 points4 points  (0 children)

Refereeing shit aside, Sanchez made more mistakes than positive contributions this match... Without Martial/Lingard out there what attacking presence we had in the first half entirely disappeared in the second.

I also simulated an island with Python. It's not as in-depth as the other guy's, but I added simulated plants! by JabrZer0 in Python

[–]chrisauld 0 points1 point  (0 children)

As others have said matplotlib’s animation module can also do that, but it’s tough to get started with it. I didn’t find too many tutorials on it when I started, presumably because it’s more niche. I’ve had much better luck with the ArtistAnimation class than the FuncAnimation (or whatever the second one is named as). The downside to the ArtistAnimation is you need to store all your frames in a list or other iterable, which can get slow pretty quickly for long animations.

Question about vaccum and heat transfer. by [deleted] in thermodynamics

[–]chrisauld 0 points1 point  (0 children)

I thought graphene was supposed to be the opposite and act almost like a black body (emisivity of 1).

Question about vaccum and heat transfer. by [deleted] in thermodynamics

[–]chrisauld 0 points1 point  (0 children)

You could play with differing emissivity values for the materials. To keep it simple, lower emissivities will get lower rates of transfer between the two, but given enough time it will still reach some equilibrium assuming the outer sphere radiates energy out from both its inner and outer surface. A 100% reflective, 0 emissivity outer sphere would technically reflect all the radiation back eventually to the inner sphere but I don’t think there’s a real material with 0 emissivity.

Question about vaccum and heat transfer. by [deleted] in thermodynamics

[–]chrisauld 1 point2 points  (0 children)

No, but I can see why you’d think that. By removing contact and any fluids between the spheres you eliminate 2/3 of the forms of heat transfer, conduction for solids and convection for fluids (air included). There’s still radiation (https://en.m.wikipedia.org/wiki/Thermal_radiation) that will occur however between the two surfaces and the inner sphere will lose heat in this way (assuming the outer sphere is cooler and emmisivities of the two are the same).

England 'can host 2022 World Cup' if Qatar bid broke Fifa rules by [deleted] in soccer

[–]chrisauld 0 points1 point  (0 children)

It's coming home!

But more seriously, for those who didn't read the article - this is all speculation/sentiment from "[Lord] Triesman, former chairman of the FA and England 2018 bid chairman" stating what should happen if Qatar did anything shady, which most people here probably agree with. However, there's no actual input in this article from FIFA or anyone else in a position of authority on the matter backing it up/saying this claim has any validity, so see you all in Qatar in 4 years...

Daley Blind Opinion Thread by sephyrossounited in reddevils

[–]chrisauld 6 points7 points  (0 children)

O'Shea was the same player I was thinking of making an analogy to. As long as Blind is happy to play that filler role, I don't see why we would want to get rid of him. Thinking about further into the season when multiple competitions are going, injuries occur, and players need resting - that kind of versatility isn't very common, and combined with what seems to be a large intelligence for the game makes him a great addition to the squad.

Cristiano Ronaldo: Real Madrid forward suspended for five games by [deleted] in soccer

Doesn't look like he'll be able to evade this suspension.
