      Especially impressive when you consider the etymology of the word “vaccine” and realize that a century ago vaccines were created by incubating them in a cow

    I’m holding a small device in my hand that gives me access to all of humanity’s knowledge.

    Granted, I’m using it to dick around on Lemmy, but…

      To be fair there’s plenty of knowledge on Lemmy as of today… And porn, lots of porn.

    Every time I think about doing something illegal or hear about people from only a few generations ago doing something fun but slightly illegal.

    Then I think. There is no way you could do that now the police would use all the surveillance that is everywhere and if I got caught their wouldn’t be a slap on the wrist and grow up. But it would be a serious issue for my future jobs and going to other countries.

    Makes me think I’m in a futuristic movie. Just not one of the happy ending ones.

      You are not wrong.

      When I was in junior high a bunch of us bussed to school and had to stay for lunch. All the rooms were locked so if you forgot a book in your classroom or wanted to get something from the band room you had to ask the lunch lady for the keys. They would always tell their eyes and sigh and make you wait forever then give you the keys like fifteen minutes before lunch was over.

      I day a bunch of us from grade 7-9 worked a plan. A kid asked for the keys to get their forgotten lunch from a classroom at the very start of lunch after complaining their stomach was upset.

      They got the keys and said they were going to use the washroom first then get their lunch. The master classroom key was removed from the ring.

      Another student was in the next stall in the bathroom closet to the entrance by the office left unlocked. We were allowed to come and go. They took the key under the stall and ran outside, jumped on a bike another kid had unlocked and biked to a convenience store that cut keys.

      Key cutting was done and paid for. The key was returned to the ring and the ring was given back to the lunch lady. The kid got a hard time for being gone so long but insisted it was from an upset stomach and they had been in the bathroom all along.

      Now, we had a key and could come and go as well pleased within the school. The grade 9s held the key, very few people knew about it, and it was passed down each year.

      If you tried to pull that crap now you’d probably get caught on video or something.

        This is great. I actually love these stories. Hope more people share.

        One I heard recently (I lived in Sydney for a bit) was in the 80’s you could just grab your mates and some beers and walk over the harbour bridge.

    • It was so easy.

      The amount of bank robberies commited in Germany in the 70s and 80s with a toy gun and a bicycle as a getaway vehicle. Or how every European country had active domestic terror cells Just bombing Shit occasionally and you couldn’t do fuck all about it.

      Go even further back, before finger prints. You could just go around murdering people.

    The technology behind it isn’t new, but The Thought Emporium is a Youtuber who:

    1: DIY-d a genetically modified virus to cure his own lactose intolerance (successfully)

    2: Is currently working on a biological computer that runs on animal neurons.

    3: Has livestreams where the viewers submit ideas (like making tomatoes spicy) and he designs DNA to accomplish it.

    Also he helped shut down a scam health product that contained radioactive material which isn’t particularly futuristic (actually it reminds me of the “radiation is good for you” craze in the early 20th century) but I wanted to mention it anyways.

    Being trans always was such a cyberpunk concept to me. When I was a kid was like “people can change their gender? Cool”

    We can say that… it was a sign lol.

      When I was a kid there was only one openly trans person I would ever see. A man at the library who wore women’s clothes (to put it in the terms we would have used then). They didn’t try to be feminine beyond the clothing. Very occasionally some makeup. Legs were not shaved etc.

      I was at the library on a weekly basis and saw this person all the time but it was just this one person. My mother told me not to stare or make fun of them and that they weren’t hurting anyone and could dress how the pleased.

      Now, some forty or more years later I frequently encounter non-binary people, trans people, etc. I follow the same method my mother taught me. They are just people living how they want.

      It is interesting to be that William Gibson had trans characters in Johnny Mnemonic, for example, written in 1981. That’s around when I would see that person at the library.

    Driverless cars, VR and the recent NASA experiment where four people started living in a simulated Mars environment for an year, even conducting VR space walks - all of this makes me feel we’re living in the movie Total Recall.

      Wow, I hadn’t heard about that. I’ve wondered for a while if astronauts could use VR to “escape” a cramped spacecraft.

        Google says the twins plus one other 1 yr younger child child were edited embryos using crispr to prevent them from getting HIV from their father(s). Which was and is unethical. They are supposedly doing fine.

          Yeah, the dude just kind of went rogue. One of them was fully edited, while the other has a blend of original and altered cells, because surprise surprise China’s maddest scientist did a bad job. If they’re still doing well that’s good, because it wasn’t certain there would be no side effects.

          I’m glad they and any kids they have will be around whenever we start discussing doing it properly. And yes, Dr. He Jiankhui went to jail.

          Damn that’s crazy. On the one hand, that’s really awesome that we can make it so that the kids don’t have HIV. On the other hand, I worry about people using it for really bad things… Thanks for telling me about it.

    Data compression. Something about “making less data out of … The same data” is really mind blowing, & the math is sick

      It is not that complicated, to make a simple example with strings: AAAABBBABABAB takes up 13 spaces, but write (compress) it like 4A3B3AB take up 6 spaces compressing it more than 50%.

      Now double it like AAAABBBABABABAAAABBBABABAB with 26 spaces and write it as 2(4A3B3AB) with 9 spaces it takes only 30% of the space.

      Compression algorithms just look for those repetitive spaces.

      Takes those letters and imagine them being colored pixels of a picture to compress a picture

        Once you get into audio, images and video it revolves a lot around converting temporal and/or positional data into the frequency domain rather than simple token replacement.

        Wait, isn’t your first example goes from 13 spaces binary to a 6 spaces of base 12 (base 10 + the two values A or B).

        That would make the “compressed” result be 110111010111011101110011 which is larger than the original message when both are in binary…

            Fair enough. The general idea is correct, I just found that example rather jarring… It is generally more difficult to compress an already small amount of data anyway.

    Turns out we can express most of proteins, some of the time, and then isolate them. This includes enzymes, when isolated these can do things like they naturally do but now in flask, but also they do things that aren’t remotely natural but are useful for us. These things are pretty fragile usually so then some of these can be modified so that they are resistant to higher temperatures, detergents etc. This is not only the nerdy shit like advanced chemical synthesis - lots of dishwasher tablets and and washing powders contain enzymes that cut proteins into pieces (like subtilisin), so in some cosmic sense dishwasher digests your leftover food off plates

    Enzymes are still proteins, and have all problems of proteins. Turns out, you can just take the most important part out of enzyme, make it, or something functionally similar out of completely synthetic parts, and it still works. Sure, it’s not as active or selective, most of the time, but it’s resistant to things that would absolutely shred proteins. This is called organocatalysis and it was subject of 2021 Nobel Prize

    Sometimes you want to take an enzyme and make it not work. We also have a tool for that: first you have to get structure of that enzyme, or some receptor protein, and by looking how a small set of random molecules lodges in it you can make a very selective, very potent ligand, sculpting it atom by atom with no knowledge other than protein structure. If you have time and resources, this can be made to work for almost any protein (that can be crystallised)

    The LANDSAT program. Not exactly new since it’s been going for about 50 years, but it’s still fascinating and maybe more relevant than ever with concerns about climate change.

    We can get different types of data about a landscape from the different parts of the light spectrum. For example, telling coniferous and deciduous trees apart based on how they reflect light. Imagine echolocation on steroids, using light.

      I’ve had a 3d printer for years and I still can’t really get over how nuts it is. Like it feels like one of those things you’d read about in science magazines as this amazing super scientific thing the scientists out in MIT have in their labs like a supercomputer or some expensive toy people who build stuff on YouTube have in their garage next to the lathe and big fancy CNC table, but no, it’s just, here. On my desk. Being used to casually print stuff that I’ve designed myself on the computer like it’s nothing.

      My great grandad was a carpenter and I wish I could’ve shown him it. I wonder what he’d think, seeing something that was once only in the realm of handcrafted diagrammes and days of building now a few hours of modelling and printing away.
