1. ### x64 Development

I'm curious, for everyone that's been able to build and run an x64 build of Orbiter, has there been a performance improvement, or are we nowhere close to even thinking about that yet?
2. ### New more realistic handling of docking events

Wouldn't this be more on the vessels themselves though? What if there's a docking system that incorporates three stages of docking? A very soft capture, soft capture, then hard dock? Or what if we're doing more of a science fiction ship and the handwaved explanation is the soft and hard dock are...
3. ### Question ORB:Connect and Remote MFD

Two quick questions entirely unrelated to each other. What ist he current status of ORB:Connect especially in regards to Orbiter 2016? It seems the versions I've found (2.1 is latest?) are for Orbiter 2010 so maybe I'm missing something? Second, was there at one time a remote MFD program...
4. ### Modeling Thrust Vectors in Orbiter

Yes, exactly! Why not? Thrust commands in Orbiter can be treated as a VECTOR3 of the values for how much thrust each axis should provide. So full pitch up would be (1,0,0), full pitch down would be (-1,0,0), half thrust roll would be (0,0,0.5) etc. If you're mixing pitch and roll or yaw and...
5. ### Modeling Thrust Vectors in Orbiter

I hit the same problem when I was working on the same thing. You're right, mixing the roll with pitch and/or yaw is tricky. On its own, roll is inverting the direction the other engine gimbals on the axis. That part is fairly simple, use two separate rotation matrices and invert the sign of the...
6. ### Modeling Thrust Vectors in Orbiter

Yes, d is the angle, keep in mind I believe those functions need the angle in radians. When you say input level, I assume you mean "if it's full up pitch (1) then rotate the full 10 degrees up, if half down pitch (-0.5) then rotate half down?" If so, then you'd "map" the input level to degrees...
7. ### Modeling Thrust Vectors in Orbiter

It's been a very long time since I did this, I attempted to implement thrust vectoring on both my Solar Service Module and my Prometheus launcher. But I believe, what you would actually need is a rotation matrix. As I recall, you would multiply the rotation matrices for each axis by your...
8. ### News COVID-19 pandemic

A good article that quite nicely sums up why the current response in the U.S. isn't the right one: https://zerohedge.whotrades.com/blog/43910127594?fbclid=IwAR2kukeySpYNJwf-K497IYY3yWSxJgG4NdZbOaw_0VlWbeFFc3KQo4MG3LE
9. ### News COVID-19 pandemic

Ok, I'm going to be blunt, I trust neither the cdc nor the who over this insanity. Why? Their data doesn't add up. Fact: For most people it manifests as a bad cold and nothing more Fact: In many people there may be no symptoms period Fact: We're told this is serious because it has a much higher...
10. ### New Star Wars movies confirmed (NO SPOILERS!)

I saw this today. WOW! I personally think that the problems this movie had, were mainly because of the problems of 8. In other words, in 8, the story got written into a corner, and they had to spend time in 9 writing themselves out of those corners. I also feel that certain critical plot points...
11. ### Relativistic large-scale collisions

Does anyone know if any theoretical work has been done on the effects of a relativistic large-scale collision? Like if an asteroid were accelerated to 99.999...% light speed and slammed into a planet? The backstory. In a Star Trek Enterprise novel I'm reading, a major plot point centers around...

13. ### News Raspberry Pi computer, is it rational?

Most of the use cases I'm seeing aren't really for desktop computing. The 3b+ I have serves as a wireless SDR signal relay in my truck. Its built-in GPIO and other communication protocols are useful for a multitude of embedded and headless applications such as home automation, remote sensing...
14. ### Neural network for sequence prediction

Um, I hope it's ok to post here, things were going ok until I realized I needed to normalize my data and I'm a bit stuck. I created a stackoverflow question that sums up my issue. It's probably something stupid I'm just missing...
15. ### Neural network for sequence prediction

Or just any C++ libraries that are faster than Python? Preferably as easy as Keras? Really starting to feel the performance problems now :uhh:
16. ### Neural network for sequence prediction

I finally have something to play with: https://machinelearningmastery.com/how-to-develop-lstm-models-for-time-series-forecasting/ That site breaks it down enough that I actually know what I'm doing now, and I can play around and see what happens when I do things. I know Python isn't fast, even...
17. ### Neural network for sequence prediction

Well, I've found a tutorial for LSTMs using the Keras library in Python. It seems fairly good and straightforward, but it doesn't delve too deeply into a lot of the "why" of each step. https://stackabuse.com/time-series-analysis-with-lstm-using-pythons-keras-library/ My graph is also not...
18. ### Neural network for sequence prediction

Yea, I know there will be odd spikes, but I have to start somewhere and I figure these two sequence prediction problems are good places for me to start. I guess to make it simple, for now I'd just like to take an arbitrarily long sequence, train a neural net with it, and predict the next number...
19. ### Neural network for sequence prediction

Using a library to get results is fine and really what I've been searching for the most. https://www.codeproject.com/Articles/1265477/TensorFlow-js-Predicting-Time-Series-Using-Recurre This is the tutorial that I think has been the closest to what I'm looking for, but I still haven't made much...
20. ### Neural network for sequence prediction

Hey guys, I know I've been absent from Orbiter itself for a long time, but I'm working on that. But I still poke around here and hope to get back into flights and dev work one day. So with that, I know neural networks have been a topic around these parts a number of times so I'm hoping someone...
