  • I work in industrial automation and have a background in pneumatics. I think you’ll be surprised at how inefficient pressurizing/moving air is. I think the most practical solution (if you can call it that) is likely carrying an air reservoir that can be pumped up with a bike pump, and having a valve to trigger the whistle. There isn’t really a safe way to carry compressed air on a bicycle because it’s inherently dangerous to transport. There are lots of ways to make an unsafe air reservoir for example what Chris Notap on you tube does.




  • As a man, I think it’s the sort of experience that men struggle to understand because of patriarchal dynamics.

    What I mean is: if a doctor were to:

    • ask me if I have considered other forms of birth control
    • and then explain all the different birth control methods to make sure I actually understand,
    • ask if I’ve talked about the decision with my wife,
    • and then explain that a general impression of her opinion isn’t the same thing as sitting down together and reviewing all the data,
    • ask if understand how the surgery will affect my body
    • and then explain the hormonal changes my body would go through
    • etc

    before agreeing to schedule a vasectomy.

    Interpretting these questions through the lens of my lived experience:

    These are thorough but pragmatic questions. The doctor is trying to make sure I understand all the options. The doctor is a peer with special expertise and wants to make sure that I understand all the risks.

    But women too often grow up in an environment which tells them:

    • Women should trust the men in their lives too make the best decisions for them.
    • That having children is the most important thing they can do in the world.
    • A woman’s value is proportional to her utility as a wife and mother.
    • Women that have sex for fun are disgusting sluts.

    So when they get asked a barrage of questions identical to the ones I’dve been asked, they experience them very differently. Women are not irrational to hear the exact same questions very differently if they are interpreting them through the lens of their experiences. Maybe they experience those questions as:

    • “Why don’t you just stop having so much sec you slut?”
    • “Don’t you know how to have sex with out getting pregnant you dumb bitch?”
    • “Do you have your husband’s permission?”
    • “Does your husband know you’re a slut?”
    • “Do you understand that you will be destroying your value to society if you don’t have kids?”
    • “Do you understand that you will become any even crazier bitch after this?”

    And too often, the doctor really does mean that.

    Edit to add: I’d value other people’s takes too.





  • Using hydrogen doesn’t emit carbon. But the principal way hydrogen is produced is called steam reformation. It’s a process that turns methane (CH4) and water (2* H2O) into hydrogen (4* H2) and CO2 (i think, I’m not an expert). So all the carbon get emitted as co2. So it’s not better, and there are a bunch of inefficiencies too. (The reformation process itself, and transportation challenges, and leakage). But theoretically, it does centralize the emissions which would make them easier to sequester so there’s that.

    Okay, I think $80 Canadian for a case, psu, mobo, cpu, & ram is sounding pretty reasonable. I just don’t know of its enough processing power for the video stuff. But I guess if not I can upgrade the mobo/cpu or add a graphics card.

    Thanks, that channel looks great.

    Re offsite backup: Yes I don’t have so many family photos that it will be difficult/ expensive to store online. But I need to get them together first.




  • One of the really interesting things about reading this thread is noticing how these places clearly mean different things to different people.

    Like one person says how “can somebody not want a pub in their neighborhood?” A pub and a bar might not mean the same thing to everyone. To some people a bar might mean something much closer to a night club and a pub something much closer to a restaurant.

    Gas station doesn’t mean convenience store to me AT ALL. To me it’s only a place for buying gas. I would never go to one unless I was buying gas at the same time.

    Is what I call a green grocer/fruit market what other people call a grocery store?

    The questions abound…



  • I finished highschool in 2004, and I remember being taught in health class (2003?) that pot was much more potent than it had been in the 60s and 70s.

    How does the stuff available now compare to the stuff from 2004?

    My googling suggests averages of:

    60s: 2% 70s: 2% 80s: 3% 90s: 4% 95-2014: transitioned from 4%-12%

    To an average of 15% today.

    I’m guessing gains prior to the 90s were selective breeding. 90’s hybridization? Subsequently GMO?



  • Another way of thinking about it is betting your entire bankroll for 99.9…% certainty that you will win $1.

    Say you go into the casino with $1000.

    Bet:

    $1 lose.
    $3 lose.
    $9 lose.
    $27 lose.
    $81 lose.
    $243 lose.
    $729 oh wait you can't bet that much, you only have $457 left. Dang, do you bet $457 or find another $272? 
    
    Bet $457 and you win $914! Congrats you're now only down $86!
    Or maybe you lost and are down $1000.
    
    Or maybe you scrounged up $272 so you could keep playing
    Bet 729 and lose. Now you're down $1272.
    Or
    Bet 729 and you win 1458. Pay back the $272 you borrowed from your buddy, you're still up $186. 
    You just bet $729 dollars for a %50 chance of winning $186.
    

    But what are the chances of getting 6 or 7 losses in a row? 1 in 64, or 128 respectively, actually worse because roulette wheels aren’t 50/50, they’re 18/19 (18 wins and 19 losses in 37 plays on average) or worse. So losing 6 times in a row will happen 1 in 54 plays, 7 losses is 1 in 106.

    Google says roulette wheels spin 55 times per hour so with your strategy you will lose your bank roll in about one hour assuming your starting bet is 0.1% of your bank roll.
