"figure of eight" curves .... perhaps the simplest is the lemniscate of Gerono, which has the parametrization:

x = cos(t); y = sin(2t) / 2; and looks like this:

However, the lemniscate of Bernoulli may be visually more pleasing; it has a parametrization very similar to the lemniscate of Gerono, except that both axes are scaled by a factor of 1/(sin(t)^2 + 1) = 2/(3 - cos(2t)):

scale = 2 / (3 - cos(2t)); x = scale cos(t); y = scale * sin(2*t) / 2; It looks like this:

any plans to add popups to each polyline?


Project 2025 gets implemented to its fullest extent .... all 922 pages of it. Every crashes soon after.


how does reddit's stock price continue to go up even though it is a textbook example of dead internet theory?


Ads get viewed (fraudulently) by bots.


how are stockholders okay with such a fraud-laden business model?


It does feel like a large shift took place about 2-5 years ago.


Yeah I'm going into crazy conspiracy territory with this kind of, but with the advent of LLMs it would not surprise me if a large portion of social media users are false personas built by machine generated comments over time that seem maybe human. You get enough of these together pushing the same ideas and it almost begins to feel like community consensus.


I am asking in good faith as someone who's been using internet forums for over 20 years.


reddit alts per ai:

    1. Lemmy (Lemmy.ml or other instances):
        ◦ Federated: Lemmy operates on a decentralized model, similar to Mastodon (in the Twitter alternative space). This means that there is no single governing body—each instance is moderated independently.
        ◦ Focus on Communities: It focuses on subcommunities where niche interests can thrive without corporate interference. Lemmy also has a strong commitment to free speech and critical thinking.
        ◦ Federation Across Servers: Even if you're waiting for Lemmy.ml approval, you could try other federated Lemmy instances, which all talk to each other. For example, Lemmygrad is another Lemmy instance with a large user base.

    2. Mastodon:
        ◦ While Mastodon is primarily a microblogging platform, many instances of Mastodon cater to users interested in thoughtful, critical discussions. Communities are tightly moderated to avoid trolls and toxic behavior. Mastodon is another federated platform like Lemmy, so you can choose an instance that aligns with your interests and values.
        ◦ Instance Focus: You can look for an instance dedicated to intellectual discussions or more niche interests that you care about, like critical thinking or philosophy.

    3. Discourse:
        ◦ Discourse is an open-source forum software that powers many community-based platforms. While it doesn’t have the same level of reach as Reddit, it offers features like:
            ▪ Better community management tools to handle bots and trolls.
            ▪ Topic categorization, which helps in organizing meaningful discussions.
        ◦ Many independent forums use Discourse, which allows you to find active and vibrant communities where civil discourse is encouraged.

    4. Hacker News:
        ◦ If you enjoy more tech-oriented or intellectual discussions, Hacker News (owned by Y Combinator) might be a good fit. It’s known for its focus on tech, business, and science discussions with a strong community of knowledgeable people.
        ◦ While it has its own challenges, like any online community, it has fewer issues with trolling compared to Reddit.

    5. Voat (now archived):
        ◦ Voat, which was a similar alternative to Reddit, was taken offline, but it had served as a niche community that didn’t adhere to Reddit's moderation policies. While it no longer exists, there may be alternatives that have sprouted in response to its closure, though they could have similar moderation issues.

    6. 4chan/8kun (Caution Required):
        ◦ 4chan or 8kun could be alternatives if you're looking for platforms with fewer restrictions. However, be aware that these platforms are infamous for being more chaotic, with unfiltered content that can range from meaningful conversations to highly offensive posts. If you're looking for critical thinking, proceed with caution—you might encounter a lot of noise as well.

    7. Tildes:
        ◦ Tildes is another Reddit-like platform designed for high-quality discussions. It's a non-profit that focuses on having meaningful conversations. It has a smaller user base than Reddit, but it is ad-free and focuses on user-curated content.
        ◦ Critical Thinking: Tildes encourages more thoughtful posts and discussions than the typical Reddit posts, which are sometimes filled with memes or low-effort content.


mastodon is a fediverse client good to see slop propagate though


why do these ai spit out so many falsehoods?


yes, but it seems to be going exponential in the last year coinciding with their ipo


It's odd how everyone just accepts what we see looking outward into the 'universe' as established reality without ever being able to actually verify if what we are looking at isn't just a highly sophisticated hologram. A hologram would serve the purpose of keeping all us hairless apes thinking we are just floating around on a single grain of sand in a system larger than the Pacific Ocean. Quite handy for keeping us in perpetual existential crisis, and thereby in the architect's total control.


Indeed. When I think about the scale of the electron cloud around the nucleus, the prospect of observing the structure of a single grain of salt from inside the nucleus seems absurd.

I feel like astrophysicists are doing the equivalent. Not saying they shouldn’t try though …


It is remarkable how France has been getting something like 80% of their power from nukes for decades without any major accidents.


Nuclear nowadays produces ~70% of France's electricity and renewables are booming: https://ourworldindata.org/grapher/electricity-fossil-renewa...

Two close calls (level 4) in 1969 and 1980 (at Saint-Laurent-des-Eaux): https://en.wikipedia.org/wiki/Saint-Laurent_Nuclear_Power_Pl...


I agree. I think this is due to the following rules :

1. run everything above the standards without compromise.

2. having a production-independant control organization to monitor that everything is done according to 1. And that has the power to shutdown a plant.


Yet their economy, growth, industry, society etc is all basically the same as their fossil fuel burning brother and sister nations.

Things might be different this time but it turns out that so far, how you make electricity doesn't have much impact on the cost and human progress. Perhaps a future when there are excesses and scarcity on a minute by minute basis things will be different but we will have to wait and see.



"Resulting in a Level 2 event on the International Nuclear Event Scale."

A level 2 on the INES is an Incident. A major Accident would be a level 7.

A level 2 is not that bad : Impact on people and environment: Exposure of a member of the public in excess of 10 mSv. Exposure of a worker in excess of the statutory annual limits. Impact on radiological barriers and control:

Radiation levels in an operating area of more than 50 mSv/h. Significant contamination within the facility into an area not expected by design. Impact on defence-in-depth:

Significant failures in safety provisions but with no actual consequences. Found highly radioactive sealed orphan source, device or transport package with safety provisions intact. Inadequate packaging of a highly radioactive sealed source.
