Before, completing the last lesson of a group (e.g. completing 5 of 5) activated a 15 minute boost. Which allowed me stop doing lessons at 4/5 and do practice instead. Later that day, I could complete lesson 5 to get a boost for a new session.

Now, these activation steps seem to be randomly scattered across lessons. Sometimes it's lesson 2, sometimes 5. Never the last one.

Did anyone else notice this? Any idea why? How do you deal with it?

It leads me to learn longer than I actually wanted (because I accidentally trigger boosts), or leads to me 'wasting' boosts, both of which feels bad.

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

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.

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

The strange science experiment that blew a worm’s head off… and blew our minds.

This interview is an episode from /channel/UCz7Gx6wLCiPw3F-AmXUvH8w, our publication about ideas that inspire a life well-lived, created with the /channel/UCMJ6QeJUbCUuhOSYZadF7sA.

Michael Levin, a developmental biologist at Tufts University, challenges conventional notions of intelligence, arguing that it is inherently collective rather than individual.

Levin explains that we are collections of cells, with each cell possessing competencies developed from their evolution from unicellular organisms. This forms a multi-scale competency architecture, where each level, from cells to tissues to organs, is solving problems within their unique spaces.

Levin emphasizes that properly recognizing intelligence, which spans different scales of existence, is vital for understanding life's complexities. And this perspective suggests a radical shift in understanding ourselves and the world around us, acknowledging the cognitive abilities present at every level of our existence.

Two authors sued OpenAI, accusing the company of violating copyright law. They say OpenAI used their work to train ChatGPT without their consent.

It uses its limb-like rotors and wheels to move in a wide range of ways, saving energy and making it more versatile.

You can read more about M4 in the research paper: https://www.nature.com/articles/s41467-023-39018-y

M4 was also covered in an article by TheVerge posted on /c/technews@radiation.party

In all, the M4 can “achieve eight distinct types of motion,” and Caltech’s press release says it can decide what to do autonomously using artificial intelligence to survey surrounding conditions. Gharib says its abilities could be useful when shuttling injured people to hospitals or exploring other planets.
