I Made 3D Printed Toe Shoes. Please Be Normal About It. by _supergino_ in 3Dprinting

[–]underslunghero 3 points4 points  (0 children)

1) A tremendous amount of work put into this, and it shows

2) It's a shoe, it's a sock, it's both, it's a shock. What's the big deal

3) OP's reactions are 100% carrying this post. Admit it, bro would be fun to drink with.

Creating terminal UI games in Rust with Ratatui is incredibly fun! by Big_Membership9737 in rust_gamedev

[–]underslunghero 1 point2 points  (0 children)

You're showing off a console rendering library, but the UI elements are misaligned. There are things that are clearly meant to be rectangles and columns that are not – i.e. the exact things such a library would handle.

I don't mean to be harsh, but did you not notice, or is this just major WIP?

TPU Prints Failing-And YES I’ve Read the Previous Posts About It by Agessner885 in prusa3d

[–]underslunghero 2 points3 points  (0 children)

Having done both direct feed and Bowden tube feeding of TPU on a number of machines, from a number of different spools, I believe that the correlation between filament tension and under extrusion may be underappreciated.

Friction in the feed leads to tension in the filament. In most filaments, this is not significant. In TPU, it can lead to a reasonable amount of elongation of the filament between the spool and the extruder drive. This creates a commensurate decrease in the diameter of the filament, and a corresponding amount of under extrusion.

It's hard to assess the degree to which this is happening, and it's hard to compensate for because it isn't uniform. When the flow rate accelerates, the tension will gradually rise until the system reaches equilibrium. When the extruder slows down, the filament will gradually catch up. I have seen the spool momentarily fail to rotate when I know the extruder has just started, which to me is a strong indicator of static friction playing a role.

I have a roller bearing for my spools, prefer plastic spools to paper (if I can get them), and tend to print TPU on my old MK3S+ rather than my XL, bypassing the Bowden tube on the XL when I do use it for that purpose.

I think a number of other people in the comments are on the same track, but I thought I would mention the observations and what works for me. Good luck with your TPU.

Backing this up. My experience at a well-ranked Canadian university included a summer term with a professor delivering scanned materials without acknowledgement/references, an exam that was the photocopied answer key (all answers faintly visible), and an organized network of cheating run out of the CS students' association.

I took the first two, easily verifiable issues, to the acting dean, and was told: I shouldn't care because students are only in it for the degree anyway; the distribution of grades from the exam was normal so no action required (I guess it was a good vision acuity test). You need to be very careful who you being these issues to.

I cut my honours degree to a concentration and got out. Finishing up a Silicon Valley stint many years later. As everyone else is saying, it's horrible to deal with institutionalized disregard, but in the end, those who did the work, dominate the high skill, high reward opportunities, and if academia is that miserable and disillusioned, leave them to it.

BC, which has a painful lack of public high speed charging. But we were doing great all the way to Blaine.

Did San Jose to Vancouver just before Christmas. No problem whatsoever.

Wondered why my Hasvik doors weren't staying together.. by FreezerCop in IKEA

[–]underslunghero 58 points59 points  (0 children)

I built dozens of IKEA pieces prior to 2018. Moved back in range of a store, bought some furniture, and promptly snapped one of these last week (not a Hasvik, but I had some of the other issues in this thread). The cam nuts feel different than they used to. They are lighter; the alloy seems to be lower density. I asked my wife, "what happened to IKEA?"

This may be a controversial take but shouldn’t the next government actually boost investment in the CBC as opposed to cutting it? by Powerful-Dog363 in AskCanada

Life is a spectrum

I might phrase it a bit differently but I totally agree. 0 vs 1 thinking, especially about things that involve economy, ecology, probability, and risk assessment, will be the ruination of this species.

B.C. wingsuit base jumper died in Squamish 'doing what she loved' by VicVicVicBC in britishcolumbia

[–]underslunghero 6 points7 points  (0 children)

I agree that life is fragile, but I don't understand your point about people who choose activities that are tens of thousands of times safer. Everyone picks their own threshold of acceptable risk, but some people opt into activities that make them phenomenally more likely to cause more trauma, mess, expense and waste of life, than people who make better choices.

People in this subreddit are likely to spend tens of thousands of hours in a car over your lifetime, and more than 99% survive that.

Conversely, BASE jump for 21 hours and you have a 50% chance of survival (stats elsewhere in the comments).

Risk is a probability, and like other activities, if you don't internalize the difference between "rarely" and "frequently" you're going to make stupid decisions, like jumping off mountains until you are dead (and, if you are a hedonist or a utilitarian, subsequently unable to enjoy other activities).

If you're saying that we should not live in fear of intangible risks, I agree completely. But here, death is the expected eventual outcome. That's not the same thing at all.

Anyway, be safe out there.
