Just a really faint memory but I recall during COVID there was big negativity with USPS not doing their due diligence to select the best option and some other shady USPS dealings at the time.

Ehhh....as a Linux beginner on Ubuntu I disagree... I spent a couple hours trying to get an AppImage application as a desktop icon.

My secondary monitor flickers to black randomly for a just couple minutes after startup and there's no way I'm going to dig through Wayland to figure out why. Monitor orientation is incorrect on startup and I again don't want to dig through Wayland or whatever cfg file I need to open.....yet.

Trump believes Taiwan "stole" chip making technology from the states. And judging from most Republican's general stupidity on this matter... They think majority of the semiconductors are produced in China. Because to them Taiwan == China.

Here's the issue I have with your position... AI is such a generic term it's difficult to have a fulfilling conversation using it but in my field a form of AI like machine learning is going to eliminate an entire sector of manufacturing... Boutique precision machined components have been thought as an impenetrable wall against AI but it's basically the same lackluster defense used not long ago about Generative images couldn't produce hands properly... It's not a matter of if but when.
Imo, the catastrophe happens when a successful AI scales. Or perhaps rather how suddenly a successful AI model will bury the existing system into irrelevancy. Boeing and most aerospace manufacturers have a machinist union but none of that will protect against a future where people are no longer necessary.
I don't think it's wrong to have AI eliminate jobs but it shouldn't come without warning. I think it's rather forward looking to be monitoring ongoing AI projects and establish contingencies for folks who will become displaced by it's rapid spread.
Trying to get capto systems for the multi-task lathes and zero-point pallets for the mills. I do prototyping and it's the only way to stay sane.
If your power consumption is actually 250 then go for a 500w PSU. You'll get better efficiency.
Anandtech (rip) used to be my go-to for PSU efficiency curves.

There's so much untapped potential with a probing system and macros that aren't being utilized at all.
This video demonstrates how powerful a quality machine and probing can be towards a future of automation and simplifying incredibly difficult setups.
What gets me unsettled but also inspired is... This isn't entirely limited to the machine tool or probing system demonstrated on the video. We can do this NOW. Existing machines are entirely capable of exploiting their probing systems beyond their usual simplistic usage (part pickup, measurement). And the only thing really lacking is the brains to figure out all the heavy duty math.
"A strive for continuous improvement" vs "good enough". How Japanese quality came to trump America post-ww2
I thought this was an extremely insightful documentary about why "Made in Japan" speaks volumes about quality versus the "Made in USA" counterpart. We as machinists are an intimate and integral component to the quality chain. Look around you, Japanese machines and tools dominate the precision market. Okuma, Yasda, Makino, Mazak, Mitsui-Seiki, dmg Mori (the Mori Part at least). While All American brands with the exception of Hardinge are left as a 'value' brand.
I never really liked the phrase "it's good enough". It always gives the impression to me that they've never really had to put something together and have it perform. I hear this all too much in job shops that make parts rather than assemblies. Never in Tool & Die. Sure, the component has a .010" tolerance but if the machinist was to hold everything within .001 or less, it makes assembly work a lot more consistent and predictable.
The linked video is part 2 of a 3 part video series.
Here is part 1 youtube
part 3 youtube
So what's your thoughts on quality? Does the shop you work at feel like they value your effort towards quality?

Glue? Threaded from the bottom up?
How does one...Rough?
Running into a dilemma...
I have no trouble ending up with an accurate finished part with really tricky features.
BUT...BUT I can't figure how to quickly develop a roughing strategy. I'm always doing short run items so I don't have many opportunities to be hogging out material repeatedly. So, when I get a 1pc job that needs a lot of material removed, I'm very slow.
To a point, where I'm getting micromanaged.... on roughing.
I'm inclined to be safe and prioritize process stability over Material removal rate. For example in HEM, Instead of doing 10% stepovers, i'll do 6%. In turning, I'll keep DOC down on the bottom left end of recommended specs instead of burying past the insert radius. I don't get off on huge MRR like others, my moment of glory is hitting incredible tolerances on a difficult design/material.
What really scares me is... that a mistake in roughing parameters comes with bigger risk than just "tighten the bolt until it loosens up and quarter turn back". It's the part becoming a projectile/scrap, machine damage, and at worst an injury. Lathe work where I have only a fraction to hold onto and inches of material to remove....
How have you developed a 'sense' for how aggressively you can rough?

Mandatory security check followed by a long travel to area of work. When do you clock in?
I'm in a situation with my manager who is suggesting that clock-in starts when the employee arrives to the site of work. Effectively saying that everyone should be coming in 15 minutes earlier than their start time.
The majority of what I read online was about security checks when leaving the premises instead of entering. And the results of a couple class actions seem like the law has loose interpretation.
Wondering what your experiences have been like dealing with this situation. Are you paid for your time traveling on company premises?
For ref this takes place in California.

DT1900 PRO Found the source for creaking/rattling and a solution.
I've owned the DT 1990 Pro for a couple years now and it's absolutely the best set of headphones I've ever used. But fairly recently the creaking issues that many other users reported have crept up to me.

Basically anytime I moved my head around I would hear what sounded like a piece of plastic being rubbed against another piece and causing creaking noises. I tried to tolerate it but alas it was too much. ____
The Problem
The molded plastic of the earcup and the plastic frame of the driver are sitting in a way to cause minute rocking when the headband flexes the earcup from head movement. Imagine the outer plastic as an ellipse and the driver as a circle within the ellipse. The circular driver will be free to rock within the ellipse shape of the outer plastic. Even if the driver finds a point to settle, flex introduced into the cans via headband will cause distortion which forces displacement of the drivers causing creaking.
Although, perhaps the driver isn't meant to be 'over-constrained'... To explain further, the retaining ring clips on to the earcup and compresses the foam pad and driver which also has a soft pliable material glued to rest against 3 prongs on the ear cup. This technically prevents the driver from flying about in the earcup. Where it gets over-constrained is from the frame of the driver making many many point/area contact around the earcup. Thus causing a binding condition to occur.
_____
Solution
One purported solution was to loosen the two T6 flat head screws that hold the earcup. This reduces the amount of earcup flex caused by the headband which does reduce the amount of creaking but will not eliminate it all together.
The solution then is to restrain the driver within the earcup in a way it wont creak.
You'll need to take it apart to access the driver.
Dissembly
-
Remove the earpads, plenty of videos on how to do this but all it only takes a light pull to remove it. random 3min YT video
-
Unclip the retainer. I found it easiest to wedge a flat head down into the smallest of the 4 tabs. Small push no prying. See image. https://imgur.com/20dG9Ma Once one came out the rest came out easily.
-
Now you'll have access to the driver. Mind the location of the key and push down around the driver. It didn't take much force to cause the creaking. See image https://imgur.com/Qb4V1lJ
On my particular headphone I noticed an up-down creak (relative to the picture).
-
To remove the driver, place your hand over the driver in preparation to catch it then flip the earcup over. It should just drop out. A couple taps was necessary for me.
-
Shim one side where the creaking was the worst. I chose to use a piece of teflon tape, it's thin and I suppose the reduced friction helps? The plastic frame of the driver is fairly skinny so I cut the tape in half.
This is where you might have to take it differently since your earcup/driver dimensions&form(shape) will be different. I did consider taking a file to it and shaving off a bit around the perimeter so the driver isn't over-constrained but I didn't want to go that route unless necessary.
- Put it all back together. _____
Conclusion
It was fun looking for a solution. Root cause analysis is something I attempt do all the time as an R&D machinist.
It's a huge relief to not have to put these headphones away either. Since these are the most priciest set I have.
Let me know if this worked out for you.
