    I don't see any reference nor any clear argument supporting your claim that RPN and postfix notation are different. Again, RPN and postfix notation mean the same thing. Here are so…

    I don't want to name any particular people or groups, because everyone makes mistakes and has limitations. I will say this: in my personal experience, I've been a part of groups th…

    No. RPN and postfix notation refer to the same core idea. From Wikipedia: "Reverse Polish notation (RPN), also known as Polish postfix notation or simply postfix notation, is a mat…

    Yes, "postfix" is commonly used. See http://www.cs.man.ac.uk/~pjj/cs212/fix.html or https://en.wikipedia.org/wiki/Reverse_Polish_notation

    It does not necessarily mean a lack of trust. It could be different incentives or priorities. For example, some users might desire major redesigns of past work but not bear the cos…

    I am unfazed by this observation. When it comes to design, sometimes ‘perfection’ isn’t available. By the way, the idea you mention may also be true for democracy: the quote goes s…

    Can you share the context for the graph? Do you have a formal definition for how you are using ‘fairness’?

    Comment #19573894

    But there is a downside, by your own logic. If you vote for a candidate that you disapprove of (don’t want to elect), you run the risk of increasing their support.

    I appreciate your opinion, but I want to point out that our definitions of fairness and simplicity may vary. Much of scholarly work around elections systems strives to ground itsel…

    Arrow’s Impossibility Theorem, as I understand it, applies quite broadly to voting systems. To put it simply, you can’t avoid it. You just decide what trade offs you want to live w…

    Enlightened morality often means being mindful of tradeoffs. Not doing an exhaustive search of academic literature because it is prohibitively expensive or time-consuming is a clea…

    Sometimes, but it can be a bit more complicated. Perhaps it is accurate to say the most mobile, unattached people tend to go first. Perhaps the more loyal people stick around longe…

    I appreciate some of what you say, but: 1. I'm skeptical of a claim such as "But the actual medium doesn't matter as much as the practice you follow". I recall hearing about studie…

    However you would prefer the term be defined and used, for decades, people have used the term "artificial life" to include cellular automata. Sources: https://en.wikipedia.org/wiki…

    It all comes down to your definition of "we". In short, this is either a collective preference problem (e.g. not enough people care or pay attention) or a collective action problem…

    50? That would be nice. For any given forward-thinking issue, I consider us lucky to have a handful of innovators at the state level. Now, when a crisis of some sort comes around, …

    I'd like to see more projects consider this approach for updates. Would anyone like to share other examples of this sort of thing (such as in other compilers or tools)?

    Comment #18570753

    Sometimes people use "compete" in a casual way that overlooks key economic connections. Competition is a force that is always present, even if it is not currently the "most obvious…

    Think of shipping as an optimization problem where various modes are selected for different parts of the path. You have to run the optimization problem to see what mix makes the mo…

    I interpret this comment as saying: if you find yourself in that kind of situation, look around and try to find other opportunities. In other words, life is too short. I also can s…

    Well said. There are many kinds of behavior that may be considered "out of specification" or not adhering to a contract. Here are just four: * https://en.wikipedia.org/wiki/Undefin…

    Comment #18434822

    I'll put it this way: "perfection" is too overloaded of a word to be particularly useful in this context. I prefer to say it this way: I want software to adhere to a contract. That…

    Upvoted since this is a useful comment and worth mentioning. I'd expect some downvotes are based on negative reactions to this part of the comment: "the title is as dumb as dumbnes…
