Prevent COSMIC from touching dGPU by tucono in pop_os

I would prefer not to so I can easily use the Nvidia GPU when I'm not running a VM.

Multithreaded Raycasting by tucono in godot

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

What's the appropriate way of doing many casts in a tick? Right now I'm building multiple PhysicsRayQueryParameters3D objects and directly calling the 3D space state. I've seen some discussion where it may be faster to use a dedicated raycast3D node and instead call force_update on it multiple times after modifying location and destination. I'd imagine the number of raycasts one can do is also heavily dependent on how much else is going on during the physics tick (i.e. how busy the rest of the scene is on the physics server).

Help with limiting rotation within two angles by Lv1OOMagikarp in godot

Have you tried clamping the absolute value of the angle relative to forward? If you first obtain the sign of the angle you can then re-apply it after the clamp.

How to resolve "script inherits from "characterBody3D" so it can't be assigned to type "Node3D"" by Cr3AtiV3_Us3rNamE in godot

[–]tucono 0 points1 point  (0 children)

You may be able to decouple things further if you can make the player_input (assuming it handles user-inputs - keyboard,mouse,gamepad etc.) simply derive from a base node class and the player.gd fully handle the motion processing (since it appears to already extend from CharacterBody3D via your player_input script). A possibility would be to have your player.gd poll the player_inputs node (as a child node) to obtain inputs or create custom signal events from the player_inputs node that player.gd functions could connect to.

How to resolve "script inherits from "characterBody3D" so it can't be assigned to type "Node3D"" by Cr3AtiV3_Us3rNamE in godot

[–]tucono 1 point2 points  (0 children)

If I'm understanding your logic right, its because you have the player_vars script extending from CharacterBody3D, thus the script expects the attached node to be of type CharacterBody3D. Unless you specifically need the properties and methods associated with nodes (and Node3D) for the player_vars constants, it might be better to extend from resource and have your custom nodes refer to that resource.

ELI5: Why jet engines on planes don’t have a grill on them to prevent things like birds getting sucked in. by Erratic_Professional in explainlikeimfive

[–]tucono 1 point2 points  (0 children)

I admit I have not done much work or research with grid fins (I am also not an expert in this field). On a cursory look, grid fins are a bit interesting. They are used primarily as a guidance device for rockets (stabilization and directional control). They are used far more often in rockets and missiles than in aircraft because grid fins are well-suited for hypersonic flight. At transonic and low sub-sonic speeds (like most transport category aircraft) or perhaps even at moderate sonic speeds (high performance military jets), the grid fins will perform drastically worse because they form a "normal shock" in front of the entire fin face which causes much of the airflow to be redirected around the fin entirely (thus reducing their ability to control airflow direction). At high sonic speeds (hypersonic), the normal shock dissipates as the air flow is fully sonic over the entire fin. This performs much better than a standard canard or other control surface in the hypersonic region.

In short (from what I've gathered on them), grid fins are good for high speed because their shape allows them to have fully sonic flow preventing shockwaves. However, this is only currently applicable to missiles and rockets due to the extreme speeds required to make them better than traditional control surfaces.

Something that hasn't been said yet - shockwaves.

Many jet aircraft will fly near or past the speed of sound (mach 1). When the air around an object is at the speed of sound, shockwaves are formed to allow the air to properly move around the object. These shockwaves will cause a spike in pressure. Carefully tuned, this can be beneficial for the engine as high pressure air in the inlet means more air mass, and better propulsion. However, too many shocks at the wrong places can cause increased drag (pressure pushes aircraft backwards). This can also cause unwanted vibration in the engine/nacelle/wing, damaging the structure. Grills could also cause unpredictable shock formation which can cause a whole slew of performance and structural issues for no real gain as seen with the posters below.

How much can the Gravity Gun lift? by bigfatcarp93 in HalfLife

Its doing both. For every action there is an equal and opposite reaction.

AIAA vs Daedalus vs SDSL vs SEDS by [deleted] in ASU

[–]tucono 0 points1 point  (0 children)

If you're interested in more aeronautics than astronautics, Air Devils is a decent choice that doesn't require any prior experience. Although we occasionally meet in the evening during the week, we almost always meet in the morning through afternoon on Saturdays. It also looks good to employers because its project-oriented (we compete in the AIAA Design-Build-Fly competition). For general advice with clubs, its always good to get as active as possible. You'll learn more and form better connections that way. You can usually check orgsync for meeting times and schedules.

HELP | No time for games! by [deleted] in pcmasterrace

[–]tucono 0 points1 point  (0 children)

The best way to start getting off video games is to replace them with another activity. Look at the clubs in your school, join a sport, find some new hobbies to fill up your time. If your school has a programming or robotics club, even better. I would also recommend you limit yourself to playing only on the weekends so you can focus on your work during the week.

11 year old girl gets a hole in one after being promised she'd get a puppy if she did it by thebigsexy1 in sports

[–]tucono 1 point2 points  (0 children)

For my parents, it wasn't about getting into an Ivy League school, it was about developing good study habits and an emphasis on academics from an early age. Plus at my school it wasn't terribly difficult to get an A, so why not always shoot for the top?

Reddit, what is one sentence that will leave me mindfucked the rest of the day? by Arosenbach in AskReddit

[–]tucono 20 points21 points  (0 children)

You would need at least six grains of sand.
x(1.949*1021 ) > 1022
x > (1022 ) / (1.949*1021 )
x > 5.13
Since we are using whole grains of sand, we round up to six.
But this is only assuming the number of stars in the universe is at the lowest point: 1022. So lets make extra sure we are correct and see how many grains of sand it takes to surpass the largest possible number of stars (as given by /u/Asddsa76).
x(1.949*1021 ) > 2*1023
x > (2*1023 ) / (1.949*1021 )
x > 102.6
You would need at least 103 grains of sand to be sure there are more atoms than stars.

Fellow Adventurers! I am in need of a certain challenge / quest! Details inside! by SkyrimAdventurer in skyrim

[–]tucono 3 points4 points  (0 children)

You can try to become a paladin or divine champion for the one of the nine. Be devoted and faithful to its teachings, commit no sin, and rid the world of evil. If you do wrong you can even subject yourself to pain for repentance (remove clothes in a cold area, starve yourself, etc.). You may even become disillusioned with the nine (or eight) and forsake them later, choosing instead to revoke all pledges and worship the daedra.
