i thought the indians already put a dot in place to denote zero?

From the wikipedia page: https://en.wikipedia.org/wiki/Numeral_system

Indian mathematicians, such as Brahmagupta in the 7th century, played a crucial role in formalizing arithmetic rules and the concept of zero, which was later refined by scholars like Al-Khwarizmi in the Islamic world.

where are you from, if i may ask?

yeah they changed the appearance of the number symbols a little bit, but i would say the real genius in the system is that it's a place-value system and that each digit is valued 10 times more than the one after it. that's the core of the system, the rest is just a make-up appearance.

edit: also that you need a digit "0" to make a meaningful math system. that's genius.

Is it?

for them, yes

internet bots were sent by the millions to destroy america, lol

i used to think that too. but is it really the case?

there's definitely a lot of wild statements on the internet today, such as Nick Fuentes neo-nazi views.

though i do wonder, are they really bots, or do people really think like that?

You know, in times where machines casually pass the Turing Test, you can't decide whether another user on the internet is a human or a machine by looking at their output alone. There needs to be a way outside of the internet (that means, in physical life) to establish who's a human and who is not.

That means, local libraries could do account authentication to make it apparent who's a real human and who is not.

Oh that's still a phenomenon today. There's a great Boondocks episode about it - s1e2 "The Trial of R. Kelly". A famous musician (R. Kelly) gets charged for peeing on a 14-year old girl (in a kind of sexual way, i'd say). During court, a lot of arguments are made:

  • (prosecutor) A crime is a crime no matter who commits it
  • (prosecutor) She was clearly underage, there's unambiguous video footage of the incident
  • (prosecutor) Where would we be if we allowed lawlessness to rule?
  • (defendant) R. Kelly is black and therefore racially persecuted
  • (defendant) Even the greeks did sexual acts with underage people, and didn't they lay the foundation for our glorious nation?
  • (defendant) His music is cool and the people like him, so who cares

In the end, people start playing music in the courtroom, people start dancing and R. Kelly is set free. It's such a comically brilliant way to display the absurdity of life. It's available for free here btw. Watch it, it's worth it.

During the whole trial, nobody thought of asking the victim whether she feels she was abused. At some point, she casually mentions she didn't mind it and would voluntarily do it again. Her word wasn't even considered during the whole trial.

what lemmy uses

see the green little button under the comment? if you click it, it shows you the code that is used to generate the graphical appearance, including formatting and image embeddings.

lol "edit your expectations" got me :D

Also as a side note, i would recommend new Linux users to not learn the command line. Do not touch the command line if you're not sure what you're doing. Like with a knife, it's a powerful tool but you can also do a lot of harm with it if you don't know exactly what you are doing.

Everything that most people need (web browsing, writing emails, watching movies, making presentations) can be done with graphical programs only. You shouldn't ever need to touch the command line.

exFAT is great for compatibility but it doesn't have journaling, so if there's a power outage while writing to a file, you can expect the file to get corrupted and unusable (which sucks). apart from that, yeah, it's great.

what i can recommend if you're working in a big organization or group or sth is to use a network drive, i.e. a drive that's accessed over the network. you typically don't have problems there.

 

I know that many people don't like complex or intransparent recommendation algorithms.

Currently, there are "subscribed", "local" and "all" categories (at least in the default lemmy web UI).

I would like to change this to include custom topics ("listings"). They are a custom way of choosing content (in case of Lemmy listings). In Lemmy, custom listings appear just like standard listings (API-wise), just that instead of "https://discuss.tchncs.de/?dataType=Post&listingType=Subscribed&sort=Active" you have "https: //discuss.tchncs.de/?dataType=Post&listingType=list:AAAA4865698@lemmy.world&sort=Active" or something.

Listings could either be lists of communities and other listings. Consider this simple text file to describe a listing for a memes-topic: (that contains 2 communities, everything on 1 domain, and another sub-listing)

c:memes@lemmy.world
c:memes@lemmy.ml
domain:memes.net
list:AAAA4865698@lemmy.world

Or they could take their data from an RSS stream or similar external source.

In regards to the recent Portland Naked Bike Ride. link

 

German wikipedia defines a biological species as a group where individuals can reproduce offspring with other members of the group, but not with individuals outside of the group.

First of all, to the best of my knowledge, proper sexual reproduction only happens with Eukaryotes. Then this means that no bacteria ever reproduce offspring with other individuals, and therefore each bacterium is its own species.

But that is a meaningless definition. If each bacterium is its own species, then the categorization into species becomes meaningless.

On top of that, bacteria have "pseudosexual" horizontal gene transfer (HGT) which allows them to exchange genetic material with any other bacterium (if the circumstances are right; if i understand this correctly). So all bacteria are in a single species if you look at it that way.

I understand that bacteria normally don't undergo HGT with all other bacteria because some might only open up at hot temperatures while others only open up in cold temperatures - thus creating a natural barrier. But it is also my understanding that while such barriers exist, they're not permanent and can be overcome in nature (without human intervention) for example due to certain virus infections and similar circumstances.

Long story short:

Wouldn't it make more sense to just consider that the concept of "species" only apples to eukaryotes and not to bacteria at all? Wouldn't that save all of us a headache? Maybe we should consider bacterial species to be less strict that eukaryotic species. Maybe we should describe bacteria by their individual features and give that group a name, instead of expecting that diverging lines of evolution cannot ever come together again.

 

Toxic masculinity is a global phenomenon, but nowhere is it more virulent than in this hypermodern, connected society. What can other countries learn from this ‘ground zero’ of misogyny?

 

It takes a lot of parts that come from different sources and also sensitivity to place every screw correctly. It might be very difficult for a purely robot-run society to reproduce the robots themselves successfully.

You might have a factory that creates trucks, but who creates the robots that work in the factory? They're a different type of robot, and if you have a factory to produce them too, who produces the robots that work at that factory? The issue might be very difficult, and even if it's possible, you probably would need a very large industrial system to successfully and reliable reproduce every type of robot.

Meanwhile (biological) living beings can reproduce themselves successfully, especially plants, given nothing but water, CO~2~, some sunlight and some mineralic fertilizer (which might already be present in the landscape). That ability to self-reproduce is amazing and might be what makes life special.


These thoughts are relevant because it might mean that robots can never really get rid of humanity, i.e. overthrow humanity's rule and kill all humans. At least a few will be needed forever to ensure the robots can be reproduced. So you have something like: Humans reproduce themselves and also produce machines, which then do most of the hard work in the world. Kinda like DNA produces proteins, which then does most of the biochemical work inside a cell.

 

I've been studying a bit of human history recently and as many of you have probably heard, the worldwide population count increased sharply in the last century or so. link

the world's population was between 250 million and 500 million throughout the entire medieval age (500 AD to 1500 AD), so i assumed 330 million people on average (which it was around 1000 AD). 330 million people for a thousand years makes 330 billion human-years.

In the time period since 1970, approximately 6 billion people lived on earth on average, so that makes 55 * 6 billion = 330 billion human-years.

so, roughly speaking, as many human-years happened since 1970 than in the entire medieval history.

that might do a part in explaining why technological and societal progress has been so fast in the last couple of decades.

Futurama sucks (external-content.duckduckgo.com)

(I moved this post over from !mildlyinfuriating@lemmy.world because it fits better here)

I'm currently watching Futurama for the first time because i always kinda thought it was cool when i was younger.

I recognize now how much it sucks.

The major thing that annoys me is that it displays the world in the year 3000 as if people would still have to hold down a job to earn enough money to live. The idea of full-employment sickens me. In my mind, i exclusively do tedious things in the hope that some day, they won't ever have to be done again. Like software development. Linux only has to be written once. Once functional, it basically lasts forever, or at least close to (only minor modifications need to be made, like adaptations to a new protocol or sth).

The very idea that people will still have to work in the year 3000 is very repulsive. It shows that society hasn't matured enough yet. I hope this is not the future that we actually end up with.
