I waddled onto the beach and stole found a computer to use.

  • What would be the use case for cyborg insects, other than war and espionage? Are they smart enough for search and rescue?

    The fundamental operational range of cyborg insects, which are hybrid robots that combine a living insect with an electronic controller, is inherently restricted to the host’s natural environment. To extend their operational range, we developed a wearable diving suit for terrestrial insects. The suit integrates a miniaturised oxygen generation module with a flexible waterproof shell, enabling continuous oxygen supply and isolation from surrounding water. By fitting a cockroach, which is a terrestrial species, into this diving suit, we allowed it to survive and operate in oxygen-deprived environments such as underwater, transforming it into an amphibious cyborg robot capable of operation across land and water. The suit sustained respiration and locomotion for up to 3 h underwater, establishing amphibious cyborg insects that combine biological adaptability with engineered protection for prolonged exploration in extreme, confined environments.

    I’d like to add on this bit that people often miss:

    • In Canada, the healthcare system’s costs include salaries for healthcare workers, supplies, training, and other necessary costs
    • In the US, the healthcare system’s costs include all of the above, in addition to all of the parisitic layers. Just the insurance layer includes insurance shareholders, insurance executives, insurance overhead (marketing, admin, aggressive claims denial), lobbying, etc. Then there are similar costs from each of the private corporations that own the hospitals, the clinics, the ambulance services etc.

    That is why the American system is much more expensive and much less efficient with the money. Since Canada’s system is still partially private and it never got fully actualized to the original vision (in part because of lobbying from the US), we have some of those inefficiencies too.

    Now the thing is, a large segment of the working US population would not be able to afford healthcare because of these parasitic layers. The US government needs to enter this system to keep it afloat, but they have to pay the much higher costs.

    So for an American, not only do their taxes ALSO go towards healthcare, but the US spends far more per capita on it. It changes year to year, but double the spending is what I’ve usually heard.

    https://en.wikipedia.org/wiki/Comparison_of_the_healthcare_systems_in_Canada_and_the_United_States

    Cut out the parasitic layers. The savvy businessmen among them can find some other industry to make a profit from.



  • Seems like the solution is: don’t do exams this way

    This year, the economist decided that both the midterm and the final exams for his course would be of the take-home, closed-book type (there is a certain tradition of this at Ivy League schools). “It’s a very nice kind of exam, because as you’re giving students practically unlimited time to complete it, it lets you make it harder than normal, to see how far they can go.” In this case, Serrano changed some of the model assumptions they had seen in class, and asked students to demonstrate whether certain statements were true or false under the new assumptions.


  • I use a browser extension that sends me to a reddit frontend on the off chance I come across a post while searching. It works pretty well

    Libredirect + the fastest instance

    From the admin side, I do understand what they are saying but I think there’s a better solution to it. We run the old frontend on our instance, and it gets hammered with bots and scrapers. So if we assume that old.reddit works the same way, then it would be attractive to scrapers. But instead of locking it down, I think they could set up something like Anubis or put it behind some other anti-bot measure.





  • From the admin side, we see the following

    • lots of accounts trying to register with the same LLM generated text, or nonsensical spam in the registration application. Those get blocked
    • some accounts that immediately make it obvious that they are a spam bot by posting unrelated advertise-y content as their first post. Those get banned quickly, and usually the home instance prunes the account within a day

    The recent “DM me” spammers and the accounts that post on !selfhosted@lemmy.world are a good example of the second category.

    It’s pretty rare for a bot to be active for much longer than that. Usually some eagle eyed user will spot it and report it up the chain.


  • Welcome!

    We have some guides / infographics for new users, which you might find helpful. These two pages in particular:

    https://fedecan.ca/en/guide/get-started

    https://fedecan.ca/en/guide/threadiverse/detailed-overview

    An instance is the site where you make an account. If we extend the analogy to email, then gmail.com is one instance while hotmail.com is another instance. If you make an account on Gmail, you can’t use that login on Hotmail but you can still see content from people on Hotmail.

    Lemmy, Piefed, Mbin, Mastodon, Pixelfed, etc. are all software. It’s hard to extend this analogy out, but imagine if Google released the code for Gmail freely so that anyone could easily set up an email website that had the same appearance and functionality as Gmail. That is what is happening here.

    So in the same way, lemmy.ca, lemmy.world, sh.itjust.works and many other Fediverse instances are running the “Lemmy” software and that’s why they look and feel very similar. Where they differ comes down to the people running a particular instance, since they will have different rules for what you can do. You can find that information in the sidebar.

    Now all of the Fediverse platforms use a common and agreed upon language to talk to each other. Because Lemmy, Piefed, and Mbin software all use this language and follow a similar format, you can easily share content between all of them. That is what the second guide page talks about. They all have communities, posts, and comments, and work in a similar way.

    Usually people make one account on a forum/threaded instance (Lemmy, Piefed, Mbin), and one account on a microblogging instance (Mastodon). This is because the format of microblogging (ex. Twitter) is pretty different from that of forums (ex. Reddit), although it is technically possible to cross post in between them.
