  • The metric standard is to measure information in bits.

    Bytes are a non-metric unit. Not a power-of-ten multiple of the metric base unit for information, the bit.

    If you’re writing “1 million bytes” and not “8 million bits” then you’re not using metric.

    If you aren’t using metric then the metric prefix definitions don’t apply.

    There is plenty of precedent for the prefixes used in metric to refer to something other than an exact power of 1000 when not combined with a metric base unit. A microcomputer is not one one-thousandth of a computer. One thousand microscopes do not add up to one scope. Megastructures are not exactly one million times the size of ordinary structures. Etc.

    Finally: This isn’t primarily about bit shifting, it’s about computers being based on binary representation and the fact that memory addresses are stored and communicated using whole numbers of bits, which naturally leads to memory sizes (for entire memory devices or smaller structures) which are powers of two. Though the fact that no one is going to do something as idiotic as introducing an expensive and completely unnecessary division by a power of ten for every memory access just so you can have 1000-byte MMU pages rather than 4096 also plays a part.




  • If it averages several instances, with enough signal you could decompose a linear combination (e.g. average) of different patterns back out into its constituent parts.

    A smarter system won’t just take the mean of the votes from different instances but rather discard outliers as invalid input (flagging repeat offenders to be ignored in the future) and use the median or mode of the remainder. The results should also be quantitized to avoid leaking details about sources or internal algorithms; only the larger trends need to be reported.

    Of course you could always just keep the collected data private and only provide it to customers willing to pay $$$ for access, which handily limits instance operators’ ability to reverse-engineer the source of the data. And nothing prevents you from using separate instances for public and private data sets.



  • Open primaries invite strategic voters to sabotage the party they want to lose rather than supporting the candidate they want to win.

    Of course you can still do that with closed primaries—you just have to register as the party you want to vote for in the primaries, ignoring your own preferences. Nothing forces you to vote for your registered party in the general election. It’s slightly more involved this way since you would need to change your registration more frequently, and commit to it earlier, but that isn’t much of a hurdle.


  • Personally, I’d love it if Democrats became the right-most party by staying exactly as they are, and a new party breaks off of them or evolves out to their left.

    I’d say it’s more likely to go the other way, with the more moderate or right-leaning Democrats breaking off to form their own party and perhaps steal away the more moderate Republican voters. There are a lot of voters who would naturally align more closely with traditional Republican political views voting Democrat only because the Republican party has been taken over by a radical faction. Having laissez-faire fiscal conservatives and outright socialists in the same party isn’t really sustainable long-term; there are too many critical points of disagreement.


  • It is just as ridiculous that Republicans in California have little say in the presidency as Democrats in Wyoming.

    The Republicans in California have a better chance of seeing a Republican president with the electoral college than they would with a national popular vote, even if their particular votes carry less weight. In a sense that gives them more representation in the end, not less—their voices are ignored but they get what they wanted anyway.











  • Since you don’t understand, quotes denote emphasis or specificity, not emotion.

    Actually quotes denote quotations. When used casually around an individual word or short phrase they generally indicate that the writer is emphasizing that these are someone else’s words, and that the writer would have chosen a different description. As in: These people are described as “teens” but are probably not only/mostly teenagers. That may not be what you meant, but it’s how that text will be read.

    If you just want emphasis you might consider using bold or italics rather than quotes.


  • I’d settle for just the limits, personally.

    The part that makes me the most paranoid is the outbound data. They set every VM up with a 5 Gbps symmetric link, which is cool and all, but then you get charged based on how much data you send. When everything’s working properly that’s not an issue as the data size is predictable, but if something goes wrong you could end up with a huge bill before you even find out about the problem. My solution, for my own peace of mind, was to configure traffic shaping inside the VM to throttle the uplink to a more manageable speed and then set alarms which will automatically shut down the instance after observing sustained high traffic, either short-term or long-term. That’s still reliant on correct configuration, however, and consumes a decent chunk of the free-tier alarms. I’d prefer to be able to set hard spending limits for specific services like CPU time and network traffic and not have to worry about accidentally running up a bill.
