    Yeah, that’s my dilemma. I wouldn’t say I can support a stready stream of rockets with LDS and blue circuits yet.

    I have a nice ratioed 45 SPM starter build set up, but because it’s all ratioed then if I’m researching yellow science I don’t have a lot spare to go towards rocket production.

    I think I might add a few more resources without going too crazy and then head to Vulcanus. Building a proper smelting setup with foundries seems very cool.

    Will be next week before I get to that point though.


  • I’ve got all the Nauvis sciences automated as well as getting my first space platform set up. That’s sending a steady stream of space science down now.

    I’ve put in quite a few hours over the first two days, but won’t be able to play for a while now.

    Currently torn between trying to set off for another planet or scale up my Nauvis base to better support things going forward. Former seems more fun. Latter seems more sensible!







  • I mean, why does anything have value?

    In the strict financial sense, something is only worth what somone else is willing to pay for it. That’s the whole premise of financial trading. Getting a bit beyond ELI5 now, but most exchanges use something called a Central Limit Order Book (CLOB) to let the participants in the market see who wants to buy and sell what and for how much, and also to match those buyers and sellers. This is a good intro: https://optiver.com/explainers/orders-and-the-order-book/

    In terms of shares in companies, then they do have some fundamental value according to the market. If you buy a share in the company, you get a share of the profits (paid as dividends), which gives those shares some value. Obviously, there’s a lot of speculation too as people are involved, so emotions and wild predictions can come into play!

    Financial instruments that get traded aren’t limited to shares in companies though. There are all kind of other financial instruments that get traded every day, some are pretty basic like buying and selling different currencies. Others involve all kinds of crazy financial engineering , like the sort that caused the crash in 2008!

    Most have some fundamental value based on their attributes, so it’s a little different to the likes of an NFT. The big issues come if the values that the market has agreed upon don’t match reality, which is what happened in 2008.


  • If you strip things back, the most fundamental point of a market is to bring buyers and sellers together and to enable price discovery.

    The price of a financial instrument you see on a stock exchange or similar is simply the last traded price between a buyer and a seller. If you want to buy or sell something, then the price you get depends on who wants to sell/buy on the other side and what price they have put an order in for.

    The more trades going on in the market, the more likely it is that you will be able to buy at a price close to what you see as the last price in the market.

    If you only allow trading every hour, then you lose some of that price discovery.

    Additionally, as already mentioned, trades would likely still happen, but away from the designated marketplace. If I want to sell something, then I may just ask who else has the thing I want to sell and try to negotiate a price directly with them.

    That way, fewer trades happen in the marketplace and more trades happen in private away from there.

    That sort of limited trading does happen for some very niche products that don’t have a lot of potential buyers and sellers. For common financial instruments, have a lot of participants wanting to trade, having a centralised marketplace helps avoid the issues that would come otherwise.

    Now, you can argue that in practice it doesn’t work as well as the theory, and I would agree there. If you are a HFT, then you can make money by getting in milli or microseconds ahead of others.

    For a lot of market participants, that doesn’t really matter though. The big banks typically don’t do that sort of trading. They are buying and selling on behalf of their clients, both individuals and companies that want access to the market. The bank makes their money by charging a margin to their client (similar to how it works for pretty much any retailer), and the fact that the HFTs are making all these trades helps them with price discovery and liquidity (ensuring there is someone to buy what they want to sell, or sell what they want to buy)

    Although filling an entire trunk full of peanut butter, let’s say 500kg worth (assume a 450 litre trunk and density of 1.1 kg/l according to Google), then adding all that weight over the rear axle would affect the handling and balance of the car, potentially making it dangerous and therefore illegal to drive.

    So, it’s not actually that clear cut that it wouldn’t be illegal!



  • So I deleted the story before I posted it, and began to realize that even though I’m 40, and should be past all this, it still hurts, and I’m a deeply broken person.

    The thing about trauma (and it likely is trauma) is that it often just doesn’t go away on its own and you need to do work on it. So, why should you be over it?

    Should is a loaded word as it pretty much always comes from what you learned as a child. You should do that. You should be like this.

    That “should” probably comes from your father when he told you how you should be as a child.

    It sounds like you aren’t over it now, but that’s ok. It’s ok not to be over stuff that happened in childhood. But the important thing to understand is that you can get over it with work. Being aware of that is the first step on that road.






  • Technically they don’t asymptotically go to zero. The minimum yield is the maximum of 20% or 20% of the original yield.

    So at worst, an oil field will produce 2 oil/sec, which can still be bumped up by speed modules/beacons as well as mining productivity.

    It’s not going to be enough alone for a large base, but I’d say it’s a lot better than almost useless.
