I needed this explanation for "L'Engle":

References A Wrinkle In Time by Madeleine L'Engle. Characters cross great distances by "tessering", moving via a tesseract through a higher dimension which essentially brings the two ends of the journey together from the perspective of the traveler. The image shows the two ends of the gap being brought together, with the gap apparently crumpled in between them.

I agree that Hitler should have been assassinated. Therefore, I am as much of a hero as those who tried.

It can bother people who believe in omnipotent deities.

[–] Spzi@lemm.ee 2 points 3 months ago

Confirmed. At first I was confused about the comments. Good idea, an obvious opportunity!

I heard that early childhood (first weeks, months, maybe years) are vital for development of emotional intelligence. Neglect could lead to life-long struggles. So I'm happy to hear you favor the idea to stay and care. Good for you, you both, and all of us.

burning teslas owned by random people when it seems it would be easier to burn this fucking nazi asshole?

Because simply in practical terms, it's the other way around. There's a Tesla right next door, but only one Musk somewhere, probably not where you are. And mostly, one has personal bodyguards, while the others just sit on the road.

Offering a slight damper / correction:

This is about two things (design and ownership), which are correlated, but not identical.

Malicious design can be things like:

  • Algorithms to keep people engaged
  • UIs to confuse users (luring them to purchases, or making 'cancel' hard to access)
  • Using intermediate currencies to make it harder to assert value
  • ...

Obviously, these patterns and practices can also be applied to a FOSS instance you own. There is less incentive to do so if the profit motive is removed - which makes a huge difference.

These design patterns are fundamentally about making user numbers go up. Attract more users, keep them on your platform longer, make them leave less. And a portion of user guidance mixed in. None of that is inherently evil, to some degree even desireable, and to some extent unavoidable to offer a functional service.

Some users may expect a feed like lemmy to browse indefinitely, since they find it inconvenient to have to click to go to the 'next page'. And because they got used to this feature elsewhere. Others already see this as a dark pattern.

I just wanted to highlight how some of the malicious stuff may still be present in the fediverse, without any company involved. Here, we're kind of in charge on both sides: Each is responsible for their own user agency (like controlling your online hours, or what sites you visit), and collectively to decide what user experience we want to shape (which might include controverse patterns).

I spent way too many words on this. Mostly I agree with you! And overall, users will encounter far less malicious patterns on FOSS.

Same here. My max is about 5.5'' and 160g. Otherwise I feel it's too hard to carry and handle, or even just hold. I also want to be able to reach the opposing screen corner with my thumb.

So is social media, and the openness of free societies to internal (the rich owning the media) and external (foreign adversaries) tampering. Spreading misinformation, eroding trust in institutions and truth itself, poisons like that.

Many democracies are crumbling this way. We yet have to find an effective antidote.

Regardless of the voting system, there still is a worryingly large portion of voters who were corrupted to serve other's interests. And that is true to all (?) countries. That not just any two democracies fall first, but GB and US, kind of shows us that it could be anyone.

So while it is easy to look down on the fallen, or feel ashamed to be that - we're helpless in this together. Hate to end like that.

There is so much in this direction. For a fraction of the budget, you could obliterate both the Russian army and economy, without losing any soldiers. What an opportunity, what a deal. Unless you're owned by Russia, of course.

none of the people critiquing Bernie have offered up a tangible suggestion for what Bernie should be doing instead, rather just pointing out how ineffective they feel Bernie is.

People reacting to activism, in a nutshell.

Running around with StreetComplete, the app sometimes tells me to leave a note instead, which I do. Short time later, I receive an email that another person has resolved my note. That's nice, but wouldn't it be better to do it all on my own?

I think I need a more powerful Editor for that, and installed Vespucci. Now I'm scared to break things. What are the next steps, how to proceed?

Hello everyone!

It’s been a while. I hope you are all well.

Unity has recently taken some actions to change their pricing policy that I - like most of the community - do not condone in any way.

I have been using Unity for more than 10 years and the product has been very important to me. However, Unity is a public company. Unfortunately that means that it has to serve shareholder interests. Sometimes those interests align with what is best for the developers and sometimes they do not. While this has been the case for a while, these recent developments have made it increasingly clear.

Unity has pulled back on the first version of their new pricing policy and made some changes to make it less harmful to small studios, but it is important to remember that the realities of a public company are not going to change.

Luckily, there are other ways of structuring the development of software. Instead of a company owning and controlling software with a private code base, software can be open source (with a public code base that anyone can contribute to) and publicly owned. Blender - a stable 3D modelling software in the game dev community - is free and open source. In fact some of the largest and most advanced software in the world is built on top of open source technology like Linux.

The purpose of this post is not to denounce Unity because of a misstep, to criticise any of its employees or to tell anyone to “jump ship”. Instead I want to highlight the systematic issue of organizing large software projects under a public company and to let you know that there are alternatives.

I believe that the way to a stronger and more healthy game dev community is through software created by the community for the community. Software that is open source, democratically owned and community funded.

Many of you have been asking for us to produce new tutorial series on alternative engines such as Godot, which is currently the most advanced open source and community funded game engine. I don’t know yet if this is something that we can realise and when.

I can only say that I have started learning Godot.

Best of luck to all of you with your games, no matter what engine they might be built on!

Sincerely,

Asbjern Thirslund - Brackeys

 

I'm often unsure how to rate the surface quality of an inherently rough surface, like sett, paving stones or cobble stone.

Question 1: These surfaces are defined by having seams. So would it ever be right to rate them as 'seamless'?

Or should we rate them as 'seamless' when they only have the expected amount of seams? Especially cobblestone makes me wonder, which usually comes with large seams and a rough and irregular surface.


Question 2: Tactile paving for blind people. Does that make a surface rough for you? In a way, that's literally how this paving becomes tactile, right?


Question 3: A pedestrian crossing going over a traffic isle (but marked as one continuous path). Assuming otherwise perfect surfaces, does it have 'cracks' (since it goes over 4 curbs), and a 'rough surface' if it has tactile paving?


Question 4: The marked entitiy is a wide area, not a narrow path. You're asked to rate it's surface quality. The area is mostly flat and smooth, but has some cracks and potholes in a few localized spots.

Do you mark it as 'a little bumpy' because that's how it would feel if you walk/bike over the bad spots? Or do you mark it as 'perfect', because it's easy to find a way through without encountering any obstacles?

 

Video Description:

Direct Air Capture (DAC) has been getting more and more attention over the last few years. Could we avert climate change by pulling carbon dioxide out of the atmosphere? Could we not just stop, but actually reverse the damage done? Unfortunately, most don't fully appreciate just quite how much CO2 we've emitted and the outrageous scale of the problem facing us. Today, we apply the fundamental principles of thermodynamics to question whether this is even feasible.

Written & presented by Prof. David Kipping. Edited by Jorge Casas. Fact checking by Alexandra Masegian.


Channel Description:

Space, astronomy, exoplanets, astroengineering and the search for extraterrestrial life & intelligence.

The Cool Worlds Lab, based at the Department of Astronomy, Columbia University, is a team of astronomers seeking to discover and understand alien worlds, particularly those where temperatures are cool enough for life, led by Professor David Kipping.


CHAPTERS (and key bits)

  • 0:00 Climate Change: Some CC is needed just to maintain a level.
  • 2:44 Removal Requirements: We released 37 Gt of CO~2~ in 2022.
  • 3:38 Possible Solutions: Trees are good for 4 years, then no space.
  • 5:03 Introducing DAC: IPCC estimates 20 Gt/yr @ 2050 required.
  • 5:43 Climate Anxiety: This video is sponsored by betterhelp.
  • 7:12 DAC Principles: Currently 19 DAC plants remove 10'000 tCO~2~/yr, or 0.000003% of global emissions.
  • 8:14 Scalability: Why this video focuses on physics, not economics
  • 9:29 Thermodynamics: Why DAC is a fight against entropy, introducing Gibbs. Lower limit: 120 kWh/tCO~2~
  • 12:08 Progressive DAC: Starting in 2025, remove how much and how fast?
  • 13:32 RCPs: Why 2.6 is discarded, why 4.5 is chosen (with an outlook on 8.5)
  • 15:09 Simulations: For 450 ppm, we need to scrub 20 GtCO~2~ in 2050. For 350, almost 80 Gt.
  • 17:03 Energy Requirements: 450 ppm requires 5% of global electricity. 350: 15%.
  • 19:34 Efficiency: Above numbers assumed 100% efficiency. Current estimate 5%, measured 8%.
  • 21:21 Conclusions: It's tough to do, but just possible. Easiest way: Stop emitting.
  • 24:35 Outro and credits
 

WARNING - LOUD!

Gav plops down the high speed camera next to a rocket engine with 45,000lbs of thrust and the results are epic. Big thanks to Firefly for allowing us to film at their facility and BBC Click for letting us use their behind the scenes footage from the day.

Honorable mention: The video was posted to https://lemmy.world/c/mealtimevideos 4 days ago: https://lemmy.world/post/4942489. I did not want to use the YouTube link as the primary link, hence reposting instead of cross-posting.

Further reading about the Lunar Crater Radio Telescope (LCRT):

They want to build the telescope on the far side of the Moon, to shield it from terrestrial (man-made) radiation. Is this premise in peril by other Moon missions? For example, do NASA or other space agencies have plans to build other bases on the far side of the moon, which could emit radiowaves which affect the LCRT?

RRFBs. HAWK signals. Do any of these devices actually do what they're supposed to do, and how do traffic engineers decide when and where to install them?

As a European, much of this was mind-boggling to me. While I believe all of this is real, I still found myself wondering throughout the video: Is this actually the norm in the US, or are these some cherry-picked bad examples? It felt for me like a whole other level of systemic hostility.

In the past 10 years or so, tech specialists have repeatedly voiced concerns that the progress of computing power will soon hit the wall. Miniaturisation has physical limits, and then what? Have we reached these limits? Is Moore’s law dead? That’s what we’ll talk about today.

  • 00:00 Intro
  • 00:53 Moore’s Law And Its Demise
  • 06:23 Current Strategies
  • 13:14 New Materials
  • 15:50 New Hardware
  • 18:58 Summary

 

Topics covered in this informative video: potentiometer, electrical engineering, basic electronics, what is a resistor, resistors in series, variable resistor, power electronics, current limiting, Carbon film, carbon composite, Metal film, Potentiometer, Thermistor, RTD, LDR, Light dependant resistor, SMD, rheostat and much much more.

The video often (not always) describes resistors as coiled wires. Don't they induce magnetic fields and currents in other components? This article answered these questions for me: https://eepower.com/resistor-guide/resistor-fundamentals/resistor-inductance/

TL;DR: Yes, but the effect is often negligible or the application does not care. When it matters, we can minimize the effect with appropriate designs (i.e. without coiled resistors).
