Probably best topic for me would probably be how to statistically model quality in manufacturing. Like what is hypothesis testing, what is a gage r&r, what is spc, how do you properly do those things, what are the footguns, how do you interpret the results, what's a spec limit vs a control limit vs action limit?

How can you manipulate the tests for your business case? To be clear on that last one I'm not saying manipulate to lie, but it depends on business. For example your control limits are typically +/- 3 standard deviations. If you run a dark business making plastic forks but to get a engineer to fly out and adjust the machine is a few thousand dollarsand no one will care if the tongs on the fork are 3 thou longer than normal. You may set your control limits at 5 times. If you make the steel beams which hold up bridges where hundreds of people die if they can't hold the forces and you're measuring width of the beams you may go down to 1 or 2 times standard deviation. Yeah you will waste engineer time which is money but it's hundred of people's lives if it fails. Those are different business cases and you shouldn't just default to the standard 3 st.dev in those cases.

Tsukomogami and Patina: In Praise of Old Things

It's the concept that old mechanical things like typewriters and camera lenses (for example) all age individually. They develop their own quirks and foibles as they are used. They almost (as in Tsukomogami) develop a soul.

We are fundamentally losing that to a society that is about consumable mass-produced trash, and on a long enough timeline, it's going to mean losing a fundamental piece of who we are as a society.

Probably the experience and implications of non-consensual teleportation. It would definitely be the most notable thing I'd done in my life thusfar.

The title of my talk is “Innovation as Rebellion against Complexity.”

I’ll start with my experience studying and teaching music history, and demonstrate how every major musical stylistic shift over the past 1500 years or so can be seen as a revolt against excessive complexity developing in the previous style. One example would be the shift from thick, complex polyphony that had become the norm in late Renaissance music, to the relatively simple and much-easier-on-the-ears style of early homophonic music. But I’d actually touch on all periods of music history.

I’d then challenge my audience to ask themselves and each other if this trend can be seen in other fields as well. Do we see such innovative rebellions in, say, art? Or literature? Architecture? The sciences? And what about technology…

…and are we on the cusp of a new rebellion against the massively complex technology that’s thrust upon us today? What does that look like? What innovations await us at the conclusion of that revolution?

I mean I’d be winging the fuck out of it with only a few seconds to prep but wouldn’t that be great to talk about?

You can see I’ve done a lot of thinking about this lol.

[-] flamingo_pinyata@sopuli.xyz 8 points 3 hours ago

Finally a worthy opponent!

Do we see such innovative rebellions in, say, art? Or literature? Architecture? The sciences?

I never thought that music went through a similar rebellion. At least not in the matters of complexity. But it makes sense. I'm very familiar with the art & architecture one. Modernism is one of the most revolutionary movements in human history.

[-] ruuster13@lemmy.zip 3 points 2 hours ago

I'd flex the confidence I've built as a social worker and without any preparation at all, ask the audience what they want to talk about. I would call upon audience members to set the subject matter content as needed and the discussion itself would be about how further incorporating mental health could help advance their industry.

[-] CADmonkey@lemmy.world 6 points 3 hours ago

There are lasers that can cut metal. I used to operate, program, set up, and maintain such lasers.

I know enough about lasers to make them seem boring and pedestrian.

[-] boring_bohr@feddit.org 2 points 2 hours ago

I've seen the xTool MetalFab laser cutter/welder thingy pop up in some DIY and metalworking YouTube channels somewhat recently and it seems wild to me that you can reasonably just buy a machine like that for non-astronomical (for an individual) prices nowadays. I mean, it I assume it probably can't compete with actual industrial machines but still, the fact that this is even feasible for a home workshop... I have absolutely no use for it but I really want one anyway, these things are so cool >_<

[-] CADmonkey@lemmy.world 2 points 2 hours ago

I've seen those too and really wish I could try one. Maybe I will get to someday.

The machines I ran were cnc, most of them cut flat material but I did work at a place that had tube lasers, which could cut things like pipe and square tube and other structural sections like I-beam or angle.

To cut carbon steel, the machine heats up a small point about .3mm across to a yellow-hot glow before blowing oxygen at it, which burns all the way through the material. If you are cutting something like aluminum or stainless steel generally you use higher power and blow high-pressure nitrogen at the hot spot, which just forces the material out of the cut. The focal point for carbon steel is right on the surface of the plate, and for aluminum/stainless the focal point is 2/3 of the way through the material.

A 4kw CO~2~ laser can cut through carbon steel up to 19mm thick, and stainless/aluminum up to 13mm thick.

[-] vrek@programming.dev 1 points 21 minutes ago

I used to repair/operate/program laser welders and cutters too. We mostly worked with titanium and either fiber or nd-yag lasers. Our cutter was 350w but 200psi of argon. My preferred cnc controllers were fanuc but they were so expensive(main controller not including servos or motors or anything else was 35k). Our cheaper machines were like 40k total but didn't have nearly the accuracy or control.

Interesting fact with fanuc is there controllers are full backwards compatible. And I mean fully. You can buy the most recent top end model and pull out some program on bubble tape and it will work. You got a program on punch cards? No problem. Also their service is top notch. You call them, a technician will show up in a day or two max with a box of every replacement board possible. They will replace the burned board then and there (no ordering and shipping) and bill you after it's fixed. Yes, it's expensive(most boards are several hundred dollars but the fee for the technician which is a few thousand) but if you make a tens of thousands in revenue per day it's worth the cost.

[-] boring_bohr@feddit.org 1 points 2 hours ago

4kW CO2, Jesus xD. I don't know if that is a lot, but sure sounds like it ^^

I'm happy I even got to work with some CO2 lasers around the 100W mark at a rapid prototyping workshop for a few years. I loved working with those, even if it was just on wood and acrylic (and they constantly needed recalibration and tuning).

Now I just sit at a computer all the time... I honestly miss that even just slightly more hands-on work ^^

[-] Dookieman12@piefed.social 3 points 2 hours ago

Strong opinions from uninformed people irritate me, so I'd talk about licensing, ownership, the pros and cons of digital vs physical copies of media, and how/whether different store fronts implement DRM so I don't have to listen to so many strong, uninformed opinions on these topics; they've gotten annoyingly common lately thanks to Sony.

The wonders of nudism.

I was reading a thread where people were talking about Japanese pronouns and remembered that this is my favorite icebreaker question.

My topic is Japanese pronouns. How they differ from English, a little bit of the history, and broadly why they should make us reinspect how we construct identity and how they complicate the idea of "individualism" vs "collectivism"

I could fill 25-30 minutes easily with no preparation.

[-] Nefara@lemmy.world 4 points 3 hours ago

The way our urban design influences society and community, and how the loss of third spaces and the dominance of cars in Western society has led to the loneliness epidemic and influence bubbles. I would talk about the movement to reclaim main street and encourage "traditional development", and how that leads to the micro-encounters that help people feel like they belong somewhere. How parks, plazas and pedestrian areas create third places where people can casually encounter diverse individuals and create friends and community connections. Also with a hearty side about public transportation and how efficient it is, and what a better neighbor a tram rail is than a road of similar passenger load. This speech is pretty much 30 seconds away from coming out of me during any conversation anyway and it's a conscious effort to stop myself. Would be nice to let it out.

Something on the subject of public transportation. Depending on the city and how much I spent in it before I was teleported (assuming the stage is in the same city), I could whip up a more or less localized talk.

[-] CombatWombat@feddit.online 3 points 3 hours ago* (last edited 2 hours ago)

An extended call for more people to follow women's sports. I'd mostly center it around bringing more queer people who otherwise don't follow sports into the fandom:

  • sports are really not that different from other serials you follow, fictional or otherwise
  • shows are better when the episodes are released week-to-week as appointment viewing
  • women's sports are pretty gay, so your blorbos will date and get married and you will squee
  • there are cute walk-up fits before the game
  • there's a big crafting subculture to make and trade custom apparel like friendship bracelets
  • sports fans are easy to socialize with because there's ongoing narratives that are well-described and well-defined
  • all the cool lesbians go to the games and the gay sports bars and meet each other
  • there is much less corruption and fewer shitty toxic people than men's sports
  • sports look simple but there are a lot of really smart people thinking really hard about tough problems and you can see what they think because they use their bodies to show you
[-] flamingo_pinyata@sopuli.xyz 2 points 2 hours ago

As someone who got into women's sport for the football World Cup in 2023, it was every bit as World Cup-y as the current men's one. Fun fun fun.
