Right. Also the speed of transition matters a lot.

Take any devastating effect that climate change might bring. Regions becoming uninhabitable, millions migrating, thousands of houses destroyed, crops failing, species going extinct.

For any of these effects, it helps a great deal if they can be delayed by years or hopefully decades. It gives everything more time to adapt. Like 10 million people migrating in 1 year puts a hell lot more stress on everybody involved (including the receiving countries) compared to 10 million migrating in 10 years.

Or your country might be blessed to deal with wildfires and floods one after the other, instead of both occuring simultaneously.

More time is worth more effort.

Much like that comment. Can you give a better example, or express why it's a bad example? That would bring some quality in.

You can find "piggy power" at the bottom of the article, headlined "How to describe your game instead".

Pixel Washer is a cozy, zen-like game where you play as a cute *piggy power washing* beautiful pixelated worlds.

I can read it in two ways: Either you're a ghostly piggy power, who is washing. Or you're a "piggy", who is "power washing". The grammar is ambiguous.

Maybe you meant to take side for the interpretation as a "cute piggy". I agree that's the most likely interpretation.

Still, this might confuse or downright misinform some readers. The main point of the article was to communicate what the game is in a clearer, more accessible way. So I found it worthwhile pointing out how it kind of fails there.

The author was concerned somebody might read a description like "Pixel Washer is like PowerWash Simulator meets Stardew Valley", and partially fail to understand it, because they don't really know what "PowerWash Simulator" or "Stardew Valley" are. Because they aren't literate enough in game titles.

But similarly, one can worry readers might not know certain words or grammatical constructions (maybe because they are no native speakers, or for other reasons), to decide wether it's a washing power or a piggy washing; because they aren't literate enough in English.

Describing your game by listing other games is tempting, but not a good idea, and I'm about to convince you why.

That did not age so well. I found most arguments rather weak. Here's an overview of all the three arguments, copied from the article:

  1. It requires your audience to be familiar with those games
  2. It creates pre-conceived notions, setting high expectations
  3. Players prefer to discover the similarities on their own

Generally, we have at least two options for describing thing A: We can relate it to another thing B ("Pixel washer is like Stardew Valley"), or we can relate it to some abstract attribute ("Pixel washer is uplifting"). Either way, we use language shorthands to describe similarities with other known entities.

About 1: Yes, that is obviously true. And it's also true for the opposite, when you don't relate your game to other games. Granted, your description becomes more accessible to a broader audience since it does not require them to know the other games. But instead, the reader now has to be able to understand and visualize what your description might look and feel like as a game (and thus becomes less accessible again). Take for example the first sentence of the proposed better description:

"Pixel Washer is a cozy, zen-like game where you play as a cute piggy power washing beautiful pixelated worlds."

I'd flag 'cozy' and 'zen-like' as probably rather less known and/or well-understood terms. I'm also not sure what 'piggy power' means. Is it even meant as one thing or is english grammar misleading as so often? Does it involve actual pigs or only their powers, whatever that might mean? But fair enough, even if all that remains not understood, the minimal takeaway is probably that it's a game with pixels and pigs and washing. So yeah, the alternate description probably works for most people.

But in the same way, a description referring to other games also works for most people.

In case of unclear references, a game-reference wins over a word-description. Like when I look up 'cozy' and 'zen-like', I may or may not come across definitions and pictures which convey the same idea as the author intended. For example, I might find results about baking cookies or shooting arrows, which have nothing to do with washing pigs. Whereas, when I look up "PowerWash Simulator" and "Stardew Valley", the results are far less ambiguous.

Argument 2 is the strongest from my point of view. But again, it's pretty similar for both ways. It should be kept in mind. Maybe it's best to ask your game testers how they would describe the game, including those who don't like it, to avoid setting too high expectations because you fell in love with your game while making it.

Argument 3 was entirely new to me. It never crossed my mind, nor did I hear anyone complain about it. I think people very much appreciate language shorthands, if they are used well and are not misleading. If so, they can save time and give a crisp description. And let's not forget that we are talking about advertisement. We know we are being lied to, that a 'fast-paced action shooter' can feel dull and boring quickly. As the author points out, these descriptions serve one purpose only; to generate more sales.

I also wanted to include a reference to Roguelikes or Roguelites. Apparently there once was a game named 'Rogue', which no one knows. But it spurred other creators to make something similar, and now we have genres called Roguelike and Roguelite. I think that's kind of funny in this context, since in this case you somewhat cannot describe the genre without comparing it to another, specific game.

Last but not least, the whole argument is probably less relevant in mainstream games, but more so in indie, or niche, new games in a creative way. When there is almost nothing which is very similar, comparisons to other games might work less well than if you're just releasing another RTS or FPS.

Nice summary. Yes, turnout. It will probably increase for Republicans. But since everybody can guess that, it will just as likely increase Democrats turnout. We should expect many effects to affect both sides, like Democrats voters now also have a higher attention that there is an election coming up. I think the effect on swing voters, if there are any left, is marginal.

Hehe, right! (technically). Context matters! When talking about fruit, people usually don't include stellar objects when weighing their options. Still true when taking in consideration that "apples to oranges" is usually metaphorical and not really about fruit.

I like that, especially this insight:

when two things have very few attributes in common or the attributes they can be compared on are very broad, general or abstract, it is harder to compare them.


A melon and a pogo stick are harder to compare, for their defining attributes hardly overlap except on a very abstract way.

Good on you to say "harder to compare" :D

it’s all semantic subjectivity. Poetry compares dissimilar things and equates unequal concepts all the time.

Another thing worthwhile to point out; subjectivity. I guess that part bothered me too. "cannot be compared" attempts to establish some kind of objective truth, whereas it only can be a subjective opinion.

The reference to poetry was nice, too.

[–] [email protected] 1 points 4 months ago

My point works just as well with an arbitrary amount of options. Someone could say "These quintillion things cannot be compared".

The number of options is irrelevant to what I tried to address. Though my examples were only pairs, so sorry for causing confusion.

[–] [email protected] 4 points 4 months ago

Thanks for taking the time to write this detailed reply. I guess you're right about the equivocation and I can see the irony :D

Though I have not fully understood yet. Following your example, the two different concepts are ...

  • in case A, we compare the value of a property (different top speed)
  • in case B, we compare the purpose or context-dependend usefulness of an attribute (different types of liquid container holders)

What blocks me from fully agreeing is that still, both are comparisons. And they don't feel so different to me that I would call them different concepts. When I look up examples for equivocations, those do feel very different to me.

I still guess you're right. If you (or someone else) could help me see the fallacy, I'd appreciate.

[–] [email protected] 1 points 4 months ago (1 children)

Agreed, yeah. Guess I was taking the word too literally.

Gripen sounds like a perfect fit. From the little I know about it, I got the impression it can be operated, just fine, under non-ideal conditions. Like using roads as runways, easier maintenance with less personel than usual and so on. I learned that from watching very short videos, so you might want to double check.

I think it makes sense: Gripen was developed by a small country close to Russia, with no reason to fear anyone but Russia. So kind of designed for the defensive underdog role.

The F-16 and even more so the F-35, are more demanding on organisation and logistics, I believe. Great when you have the capability to double down on it, not so useful when your Hinterland is constantly bombarded. Like I heard they have trouble keeping electricity and water going. Not sure if maintaining a fleet of 35s is possible under these conditions. Fingers crossed they can make good use of the 16s.

 

I'm specifically looking for these two:

They exist, but I cannot find them through the lemm.ee search, so I cannot subscribe to them. I tried all tricks of which I'm aware several times. I checked wether we blocked or defederated each other, which does not seem to be the case.

So what's the issue, and how to fix?

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.

Absolutely everything you think about yourself and the universe could be an illusion. As far as you know, you are real and exist in a universe that was born 14 billion years ago and that gave rise to galaxies, stars, the Earth, and finally you. Except, maybe not.

Other explanations for Boltzmann Brains did not require an 'inside-out black hole', for example https://en.wikipedia.org/wiki/Boltzmann_brain, so this inclusion came as a surprise to me. Not sure if it's necessary.

What baffles me about the theory: If it's true, and reality is (mostly, statistically speaking) imagined ... the physical reality could be anything. It could be very different from the reality we live in. But we created our models of the universe in this one reality we know, and the theory of Boltzmann Brains emerged from that.

So based on these physical models we arrive at the idea of BBs. But if this idea is true, the physical reality could be completely different.

Or what do you think?

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).

First, thanks for creating this community!

I liked about https://old.reddit.com/r/xkcd/ that you can expand the comic, even if the full URL was submitted (not just the image URL). This way, I could either peek the comic but stay where I am, or open the URL and still go to the XKCD site.

Recent example posts which do that:

  • xkcd 2794: Alphabet Notes
  • xkcd 2793: Garden Path Sentence
  • xkcd 2792: Summer Solstice

Here, posted comics look as if an image could be expanded, but it redirects me to XKCD instead.

Not sure how /r/xkcd did this. Any chance we can do a similar thing here?
