  • EDIT, disclaimer: I’m writing this using USD as a primary example, but it holds true for many other currencies as well.

    Because it’s not as freely traded as the USD. The main reason behind USD being so stable is because it’s available “anywhere”. And the reason for this is because it was always freely traded and easily bought by “anyone”. This results in loads of countries having USD as a foreigner reserve. On top of this, US monetary policy (not to be confused with US economic policy) values stability over anything else, resulting in a sought after currency for long term holdings, thus increasing its price.

    The Yuan could in theory serve as a world reserve currency as well, but faces some challenges:

    • Yuan has traditionally not been as freely available, so there’s simply less of it going around.
    • Chinese monetary prioritizes economic power over stability. Trumps whining about Chinese devaluing its currency isn’t completely without merit.
    • A strong Chinese economy is a rather recent phenomenon, so there’s not a whole lot of stable history to point to as an argument for buying a huge amount of Yuan as forex reserve
    • The currency is subject to whatever the CCP considers best for China, not the currency.

    This results in Yuan not being as attractive as the USD. Combine this with it being in the interest of the CCP to keep the currency somewhat low (because that’s in the best interest of their export capacity), and you get a Yuan trading for significantly less than its potential.

    I honestly don’t see this changing any time soon. Having the Yuan as the de facto world default currency is simply not a priority for neither China nor other countries. And the ones who control its value have a vested interest in keeping it low.

    It is worth noting that a “cheap” currency that can be bought for 1000 jimjams on the dollar doesn’t make it a low value currency. The exchange rate itself does not determine value, only the price. Value of a currency is derived from (percieved) future prospects of the currency. If it’s more or less certain that you can buy 1000 jimjams for one dollar, gbp, or euro 50 years from now, that makes the jimjams a valuable currency, even if the relative exchange rate is high.

















  • Kind of. But I’m also a pragmatic person resulting in a lot of contradictions. Just as an example, I despise authoritarian regimes, but my work email ends with .cn

    I consider myself an anarchopragmatist at heart; I would love to have neither Gods, kings, or mayors, but the process of implementing an alternative would most likely be worse than what we have today, at least in my corner of the world.


  • Yup, I 100% agree. Tapes are often viewed as obsolete, but there is no more cost-effective way of storing data in the petabytes in a safe way than tape.

    Hell, at work I have a few live storage clusters measured in petabytes, and being responsible for them can be pretty stressful at times. Data loss isn’t just bad, it is fucking terrifying when its data costs hundreds of thousands of dollars per day to collect.

    I have yet to experience data loss, but I breathe a sigh of relief for every batch of data that has been confirmed written to tape. Because once it is, I know that it is safe and no longer my responsibility.

    It’s written to two sets of tape at a time, both of which are read back to confirm data integrity, and once it is, that’s when I know that my live copy is officially not supposed to be a backup.

    One set of tapes is stored on board in case something stupid happens with the other set during transport to a literal mountain for storage. There it is re-read and checksummed, confirming that the other set of tapes can be rewritten with the next dataset. (Yes, every tape cartridge is written to twice).


  • Not sure if it’s still in use today, but the above description was 2008 through 2012. Msdos was used for “gun timing”, which basically amounted to extreme precision when it came to opening or shutting some solenoid valves. The computer had a GPS input and a bunch of serial outputs, and a control line (also serial).

    The control line sent instructions of which solenoid to open when, a time reference was determined by the GPS, and you can probably guess what the serial outputs were for.
