  • I honestly needed to hear this today, so thank you. I’m at work trying to work out someone else’s uncommented code and have just been staring at it mumbling to myself. I’m new to the position so I’m anxious my new coworkers will think I’m just dicking around… This is the validation I needed. Thanks everyone!








  • A great point! I feel like the overarching end goal is a meritocracy - people are rewarded for their talents and hard work. I’d wager most people agree with this goal.

    The problem becomes disentangling history and circumstance from our ability to measure talent and hard work. The only way we know to break some social norms that hinder a true meritocracy is to unfairly manipulate the playing field in the short term, which in itself does not follow a meritocracy.

    I think there are a few main obstacles:

    1. Perceived talent and hard work that was actually the result of circumstance - those that think the system is currently working and therefore their position is justified.
    2. Lack of acceptance that the goal is long term / generational. Those that are unwilling to accept a temporary ‘manipulated meritocracy’ in the short term that would allow a better one in the future.



  • Ooo there’s a great video on Minute Food about vanilla extract vs synthetic vanilla. It basically comes down to: if you cook the vanilla, synthetic will taste the exact same, if you never heat up the vanilla it might be worth getting the real stuff.

    I assume the same is probably true of most oils, if you use EVOO for salad dressings it might be worth it, but if you’re using it to saute you might as well use sunflower oil and save some money.

    Love this write up! Thank you for posting, I really like your ideas. Out of curiosity how would apartment buildings work in your plan. There are many cities where you probably don’t want to encourage single family homes to reduce urban sprawl. How would you encourage high density housing in your plan?

    I understand your sentiment, but it took all of a half second to think of one scenario that would cause problems in the proposed system.

    As frustrating as it is to hold off on a good-intentioned change, it is far more detrimental to charge headlong without considering the consequences. The systems that are in place now are there for a reason. Some of those reasons are greed and corruption, but others are because of they fulfill people’s needs. It would be stupid to build a new system to address the greed side without addressing the need side.



  • I don’t think the DC to DC conversion was adequately discussed in this article. If you were to implement a parallel DC and AC system in your home, you would need all of your DC devices to run on the same voltage, or you would need to convert them from the supply voltage to the useable voltage. The most efficient way to do a DC to DC conversion requires converting to AC to change the voltage, then converting the new voltage back to DC. If your goal is to reduce losses, these conversions would be much more efficient if you started with an AC source.

    The only time you have big efficiency gains is when you’re supplying the exact DC voltage required by the device. In a practical house this would mean having a few different DC feeds all at different voltages. That means more cabling and more electrical protection equipment per voltage.

    I love the idea that we have a DC source and DC devices, why go to AC in-between? It’s a compelling thought, but the reason is it’s a good general system that is robust and pretty efficient independent of individual situations. Can you make a more optimized system per house taking into account the amount of energy it took to extract the metal for the additional wires and the savings on each conversion device? Yes, of course. Is it practical on a large scale? I don’t think so.
