Hehe, good point.

people need to read more code, play around with it, break it and fix it to become better programmers.

I think AI bots can help with that. It's easier now to play around with code which you could not write by yourself, and quickly explore different approaches. And while you might shy away from asking your colleagues a noob question, ChatGPT will happily elaborate.

In the end, it's just one more tool in the box. We need to learn when and how to use it wisely.

While possible, it goes against the Mediocrity principle:

The idea is to assume mediocrity, rather than starting with the assumption that a phenomenon is special, privileged, exceptional, or even superior.[2][3]

That's a self fulfilling prophecy, isn't it? The effect you describe would not be there if it wasn't for comments like this. Or at the very least, these comments make the effect bigger.

Japan’s coal imports are overwhelmingly local – AUS and Indonesia.

That's roughly as local as France or GB to US east cost, similar distance and similar other differences. IMHO both connections aren't even regional anymore. But yeah, it's fairly short what coal import routes concerns.

An (intuitively) working search would be a great step ahead. It should find and show things if they exist, and only show no results if they do not. That a plethora of external tools exist to meet these basic needs shows both how much this is needed, and how much it is broken.

I also feel I have more luck finding communities if searching for 'all', instead of 'communities'. Don't make me add cryptic chars to my search to make it work. Do that for me in the background if necessary.

It's been long since I've been using it, but iirc, it's impossible or painful to search for a specific community in your subscribed list.

There’s a famous hill-top cemetery in the city, and sure enough I saw basically all of my classmates there too

That was an unexpected dark turn. Glad you live to tell their story!

I like that it comes in a can, not a plastic bottle simply because it gets colder faster and stays colder longer.

If it feels colder in your hand, it means the opposite of what you assume: It absorbs heat from your hand faster, so the stays colder shorter.

Imagine instead you hold a perfectly insulated container. You could not feel wether the inside is hot or cold, or else the insulation would be faulty.

So if you really want to have a drink that stays colder longer, grab something which does not give away how cold it is, quite literally.

You can use more debug outputs (log(...)) to narrow it down. Challenge your assumptions! If necessary, check line by line if all the variables still behave as expected. Or use a debugger if available/familiar.

This takes a few minutes tops and guarantees you to find at which line the actual behaviour diverts from your expectations. Then, you can make a more precise search. But usually the solution is obvious once you have found the precise cause.

From the title, I had a question and found the answer in the FAQ:

What’s an unconference?

An unconference is a conference in which the participants – rather than the organizers – decide which sessions happen each day and on which topics. In the many years we have been organizing unconferences, we have found that for complex subjects like the Fediverse, attendees get more value (and fun!) out of unconferences than from traditional conferences. Sounds disorganized? It did to us, too, until we actually experienced our first one. So don’t worry, it will be fine :-)

Here are some suggestions for how to prepare for an unconference.

A dark sense of hope here: At least some of us are able to adapt quickly.

[–] Spzi@lemm.ee 1 points 9 months ago

And this is another issue which hinders discoverability. It's nice there are tools and workarounds but their existence also signals the issue exists.

I didn’t say able to locate I said there being a list.

Are you confusing comments?

I see this in the referred comment:

having the capability to locate

While the word "list" does not appear.

But mostly I think we should try to read the message, not focus on single words.

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).
