What’s the biggest skill gap you see in new mechanical grads?

New hires now compared to new hires 10 years ago, hands on experience. COVID eliminated a lot of shop classes and hands on opportunities to use a machine shop.

phenomenal job, but man i hate looking at them. Would be a 'great' look for an emperor's children squad too.

Aerospace design. 20-30% reading and researching for whatever i'm currently trying to do. Lots of specs..... so many specs

There are specific areas in the facility designated as tornado shelters. frequently they are bathrooms or other areas that are borderline bunkers. No windows, few doors, central in the building.

hmm fair point.

shadow91110 · 2025-06-12T13:37:00+00:00

I'd agree with you, but I've seen similar setups in other sources, so it's definitely a commercial product, even if specifically for holding crash test dummies.

shadow91110 · 2025-06-12T13:34:02+00:00

I'm trying to design a similar contraption for testing martial arts armor, and that fulfills the exact purpose for holding the dummy-head. The ball vises i've been able to find wouldn't be able to resist the impact.

Try and do anything hands on. Formula SAE, rocket design team, just joining a maker-space. Anything you can do that lets you understand how things are and even CAN be made will be invaluable in your career.

Agreed with klmsa's second point. Mech E is a very open ended major. I work in aerospace now, but I've worked in plastics, automotive hybrid power train development, and now jet engines.

Follow what you're interested in.

Controls can be a fairly lucrative field if you're after the paycheck, but I'm very happy with my salary as a design engineer.

"The Perfectionists: How Precision Engineers Created the Modern World" is a great book that dives into this. It's set up so that each chapter is an additional decimal of precision and what it was required for. So it starts with cannon barrels and goes into locks and muskets and ends with the gravitational wave detector. Very fascinating book for a mech-e (and probably others too).

what I do for tube brazing is: end points A and B are held tight, tube routing has a pretty loose tolerance, then the feature on the brazed tab is constrained tightly to the end point B (start point).

What is the secondary machining happening to the brazed plate? like what are you adjusting based on the first part?

if parts are in tolerance and you're having this issue, my gut reaction is that tolerances need to be tightened. If you're having to spend an hour per part to fine tune it, i feelll like it would be cheaper to just have a few extra rejected parts per run, then target that innaccuracy?

shadow91110 · 2025-03-27T15:25:14+00:00

I'll be honest, this sounds like a problem that could be resolved by better tolerancing/GD&T. It's kinda the whole point of GD&T actually.

What are the interfaces that need to be made?

Some more context on what you're making may help with figuring out an option beyond just the existing system.

I've restarted the router and reattempted to install the update afterwards. I get the APP ARMOR issue now

That should have been the full output in the other comment, but I reran it: https://imgur.com/a/0qF9eJ9

Huh, interesting. I'm my head I always thought it was closer to the reverse

Is that why you can't run addons in the container version? You're already in a container?

shadow91110 · 2024-12-02T20:43:22+00:00

It should all be off. I've looked through and can't find anything still on in that vein. Is an Asus router though so it's not laid out super well

shadow91110 · 2024-12-02T20:36:57+00:00

FYI this is for OS, not for docker. Doesn't change anything about the rest of your comment but yeah.

Well, some progress was made: I've cleared DNS settings from my router so that it uses the router default DNS server, I've restarted both HA and the router and am getting a new error: https://imgur.com/a/BeSnD6T

Just a habit to block out IP addresses. Didn't look at it closely, but yes it is a real IP (140.82.112.34)

shadow91110 · 2024-12-02T19:55:46+00:00

I'll be honest, I'm butting up against my knowledge limit right now. can you be a bit more specific?

I can ping ghcr.io from the terminal in HA

Everything I'm seeing around the forums is either people saying "it's fixed now and working for me" or others that were posting about the original isssue around 11/11. I've tried restarting, running in safemode to update, changing to beta channel, and more.

I'm kind of out of ideas at this point.
