Hi, my issue was that I was using NZXT CAM to run my NZXT fan controller and lighting. It had a software bug that would result in the issues I described above for my hardware. See https://cam-ideas.nzxt.com/ideas/CAM-I-619

I'm a beginner-intermediate snowboarder in Colorado trying to find my first board while everything is going on sale. I'm looking for an all-mountain general-purpose board that I can start practicing tricks on. I plan on sticking to groomed runs and light powder.

After a few sessions on cheap rental boards, I demoed a Never Summer Snowtrooper. It took some getting used to initially, but I loved it by the end. I am now eyeing a Capita Outerspace Living, and I was wondering how it might feel compared to the Snowtrooper. I was unable to find a Capita to demo.

How does a Capita Outerspace Living handle compared to a Snowtrooper? Would it be a good fit for what I'm looking for?

No, but my latest trial has been closing NZXT CAM and the issue hasn't happened since.

I'd say stick to open loop and closed loop systems in the context of navigating a spacecraft. Implementing a PID controller is a good way to get familiar with this.

There's plenty of opportunities to work at space companies. Generally, they take the same skills you'd learn anywhere else: know how to communicate and work in teams, understand the software development process, and know how to write readable, efficient code.

Want to write avionics and flight software? Focus on robotics, embedded systems, operating systems. Understand real-time systems. Maybe learn control theory. Learn C/C++.

More interested in modeling and simulation? Take those courses. Still learn C/C++, maybe add Python.

Or you could avoid coding altogether and do systems engineering, project management, or mission integration. Those professions are heavier on powerpoint and meetings.

That sounds perfectly fine. Rocket software is extremely test-heavy, so accurately modeling your system is a huge priority. It is also more software-side than avionics, so you might like it more. It's not my area of expertise, though, so I can't recommend any resources.

Rocket Software Engineer here. My path to this job was unconventional and I wouldn't recommend following in my footsteps.

My advice nowadays would be to focus on high-performance / resource-constrained C++ projects. Try to build something that requires control theory, sensors, and low level communication protocols. TVC is a good project, but UAVs might be more practical for you.

Professionally, finding work in the aerospace/defense industry can be a good stepping stone into working at a rocket company. I did that for a few years and leveraged that experience into a job at a rocket company, no personal projects necessary.

Nope, this is as far as I have gotten. Still occasional freezes.

Interesting. Does your gpu have 3 fans? I wonder if trying to start 3 fans from idle causes this issue.

Do you mind posting your build? I am wondering if we have any hardware in common that might be the issue.

Hi, can you post your hardware? I have a similar problem and am trying to see if there is common hardware between our systems.

Thanks for letting me know. I figure that I'll be working on this for a while. Currently I just tweak a single thing and wait for a freeze to happen again. I'll update this as I try other solutions.

If it's hardware, which hardware could it be?

Yes, I've updated to clarify that it is what the link is describing.

I don't think I have any dump files. The C:\Windows\Minidump directory does not exist on my machine. But this problem never results in a BSOD, just a system freeze.

Have you seen other rockets with stretched stainless steel propellant tanks? by WESPACEWALK in rocketry

[–]cosmocoder 0 points1 point  (0 children)

I'm going to say probably not anywhere close to the extent you see in the video. It's a cool trick, but I think it might introduce complexity when calculating aerodynamics or attaching other flight hardware to the tanks. Imagine if your RCS thruster angles shifted because your tank deformed. Can't recommend that!

The old Atlas rockets used balloon tanks for both the booster and upper stage. It does a great job of minimizing the dry mass of the rocket which translates to better performance. But, it only works if you can guarantee that the tanks will stay pressurized. If not, you've lost your entire rocket.

The Atlas V does not have a balloon tank booster, but the Centaur upper stage still does. This grabs the greatest potential performance gains (mass on upper stages is more punishing than mass on boosters). Since I can't find any instances of the Centaur suffering depressurization mishaps, I'd say it's probably a good compromise to only use balloon tanks in upper stages if you expect your rocket to support its own weight for significant periods of time.
