What's up with the wiggeling, is the camera dangling from a balloon?

I guess if drones can fly into doors on moving targets, an observation drone should be able to hold relatively still.

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

FYI you can self-host GitLab, for example in a Docker container.

 

What they actually mean is rather "these two things are very dissimilar", or "these two things are unequal".

I guess in most situations "cannot be compared" could be replaced by "cannot be equated", with less lingual inaccuracy and still the same message conveyed.

To come to the conclusion that two things are very dissimilar, very unequal, one necessarily has to compare them. So it's rather odd to come up with "cannot be compared" after just literally comparing them.

For example, bikes and cars. We compare them by looking at each's details, and finding any dissimilarities. They have a different amount of wheels. Different propulsion methods. Different price, and so on.

When this list becomes very long, or some details have a major meaning which should not be equated, people say they cannot be compared.

An example with a major meaning difference: Some people say factory farming of animals and the Holocaust are very similar, or something alike. Others disagree, presumably because they feel wether it's humans or animals being treated, the motives or whatnot make a difference big enough that the two should not be ~~compared~~ equated.

Can you follow my thoughts? Are 'dissimilar' or 'unequal' better terms? I'd be especially interested in arguments in favor of 'compared'.

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.

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.

Würde ich auch vermuten. Ihre bisherigen Forderungen waren es aber nicht, mit großem Abstand. Also mal schauen.

This meme is so wrong it is deliberate misinformation. The Guardian made an article which is probably this meme's source. It even linked to the original source, the Carbon Majors Report. But blatantly misquoted the CMR. For example, CMR says something like "100 fossil fuel producers responsible for 71% of industrial GHG emissions", but The Guardian (and meme posters) omit the italic bits.

What do they mean with producers? Not companies like Apple or Heinz, but simply organizations which produce fossil fuels. Duh. Shell, BP, but also entities like China's coal sector (which they count as one producer, although it consists of many entities). CMR also states 3rd type emissions are included. Which means emissions caused by "using" their "products", e.g. you burning gasoline in your car.

So yes, the downvoted guy saying "Consumer emissions and corporate emissions are the same emissions" is pretty spot on in this case, albeit most likely by accident. Rejected not for being wrong, but for not fitting into a narrative, which I call the wrong reasons. Please check your sources before posting. We live in a post-factual world where only narratives count and truth is just another feeling, because of "journalism" and reposts like this. Which is the infuriating part in this particular case. I guess you want to spread awareness about the climate crisis, which is good, but you cannot do so by propagandizing science and spreading lies.

All that from the top of my head. Both the ominous TG article and the fairly short report are easy to find. In just a couple of minutes you can check and confirm how criminally misquoted it was.

Eventually, things settle at almost perfect ratios. Everything between creates some kind of friction.

What does it even mean to bruteforce creating art? Trying all the possible prompts to some image model?

Doesn't have to be that random, but can be. Here, I wrote: "throw loads of computation power, gazillions of try & error, petabytes of data including human opinions".

The approach people take to learning or applying a skill like painting is not bruteforcing, there is actual structure and method to it.

Ok, but isn't that rather an argument that it can eventually be mastered by a machine? They excel at applying structure and method, with far more accuracy (or the precise amount of desired randomness) and speed than we can.

The idea of brute forcing art comes down to philosophical questions. Do we have some immaterial genie in us, which cannot be seen and described by science, which cannot be recreated by engineers? Engeniers, lol. Is art something which depends on who created it, or does it depend on who views it?

Either way what I meant is that it is thinkable that more computation power and better algorithms bring machines closer to being art creators, although some humans surely will reject that solely based on them being machines. Time will tell.

[–] [email protected] 1 points 5 months ago (2 children)

That depends on things we don't know yet. If it can be brute forced (throw loads of computation power, gazillions of try & error, petabytes of data including human opinions), then yes, "lots of work" can be an equivalent.

If it does not, we have a mystery to solve. Where does this magic come from? It cannot be broken down into data and algorithms, but still emerges in the material world? How? And what is it, if not dependent on knowledge stored in matter?

On the other hand, how do humans come up with good, meaningful art? ~~Talent~~ Practice. Isn't that just another equivalent of "lots of work"? This magic depends on many learned data points and acquired algorithms, executed by human brains.

There also is survivor bias. Millions of people practice art, but only a tiny fraction is recognized as artists (if you ask the magazines and wallets). Would we apply the same measure to computer generated art, or would we expect them to shine in every instance?

As "good, meaningful art" still lacks a good, meaningful definition, I can see humans moving the goalpost as technology progresses, so that it always remains a human domain. We just like to feel special and have a hard time accepting humiliations like being pushed out of the center of the solar system, or placed on one random planet among billion others, or being just one of many animal species.

Or maybe we are unique in this case. We'll probably be wiser in a few decades.

This ambiguity is what I had in mind when I read "let me be clear". Though now I get it.

Mit der Petition wird keine Kürzung von Finanzmitteln für den Nahverkehr gefordert. Im Zuge der Haushaltskrise nach dem Urteil des Bundesverfassungsgerichts vom November 2023 wird nach schnellen Wegen gesucht, die Haushaltslücke zu stopfen. Es soll gespart werden. Dabei steht auch im Raum, die Mittel, die der Bund den Ländern jedes Jahr zur Verfügung stellt - die sogenannten Regionalisierungsmittel - zu kürzen.

Begründung

Die Bundesregierung hat sich zum Ziel gesetzt, aus Klimaschutzgründen die Fahrgastzahlen im öffentlichen Nahverkehr bis 2030 zu verdoppeln. Die drohenden Kürzungen der Regionalisierungsmittel würden jedoch bedeuten, dass Züge gestrichen werden oder gar Strecken stillgelegt werden müssten. Fahrgäste würden von der Schiene aufs Auto umsteigen, was höheren CO2-Ausstoß bedeutet und das Klima geschädigt würde. Gerade im Verkehrsbereich droht eine Verfehlung der Klimaziele. Wir brauchen aber mehr statt weniger Klimaschutz und haben nur den einen Planeten zum bewohnen.

Sinnvoller wäre es doch, klimafeindliche Subventionen wie das Dienstwagenprivileg zu kürzen, das den Staat 3,5-5.5, Mrd. Euro pro Jahr kostet. Hier ist ein viel größeres Sparpotential vorhanden - und das Klima könnte geschützt werden.

 

Alternativ: https://piped.video/watch?v=KZNvClrM6Rw

Ich gehe hier aus verschiedenen Perspektiven durch, was zu berücksichtigen ist, wenn man die Auswirkung von Heizen mit Holz bzw. Holz als Brennstoff aufs Klima bewerten will.

Das Video packt in die knapp 10 Minuten vier Detailstufen, bei denen die Schlussfolgerung mal "klimaneutral" lautet, mal "nicht":

  • Stufe 1: Klimaneutral, weil nur CO~2~ freigesetzt wird, was vorher aufgenommen wurde.
  • Stufe 2: Klimaschädlich, weil wachsen viel länger dauert als verbrennen
  • Stufe 3: Kann klimaneutral sein, wenn viele Bedingungen beachtet werden
  • Stufe 4: Klimaschädlich, weil Wald statt nur neutral eigentlich eine Senke sein könnte

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 managed to disable it, but I can't find how to remove it entirely. Anyone knows?

I'm talking about the screen all to the left.

 

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?

Original title: "Misunderstanding Your Job Description - Delivery" by Viva La Dirt League

Delivery man Byron learns some really important information about his job... that he probably should have learnt 6 years ago...

For those who don't know the show: It's important to understand that Byron is a very, very dedicated employee, who accepts any challenge, and takes great pride in his work. His colleagues sometimes don't remember him after working with him for years.

 

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.

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.
