  • I’m not debating. It is not a matter of opinion. I’m doing you the courtesy of informing you how the entire rest of the world uses the term.

    If action A looks for thing X, and it finds thing X, then the test is positive. If action A fails to find thing X, then the test is negative.

    If action A claims to find thing X, but later confirmation determines that thing X is not really there, then this situation is called “false positive”.

    If action A claims fails to find thing X, but later confirmation determines that thing X is actually there, then this situation is called “false negative”.

    That thing X may subjectively be considered an unwanted outcome has **nothing ** to do with the terms used.








  • After all these years I still don’t know how to look at what I’ve coded and tell you a big O math formula for its efficiency.

    I don’t even know the words. Like is quadratic worse than polynomial? Or are those two words not legit?

    However, I have seen janky performance, used performance tools to examine the problem and then improved things.

    I would like to be able to glance at some code and truthfully and accurately and correctly say, “Oh that’s in factorial time,” but it’s just never come up in the blue-collar coding I do, and I can’t afford to spend time on stuff that isn’t necessary.






  • None of the answers I’ve read so far actually answer your question with basic facts.

    When you invest then you are buying a tangible financial instrument: a share of a company or a treasury bill or a municipal bond and so on. There is the expectation that over time, the value of your financial instrument will increase in value but this is not guaranteed. The lack of guarantee is the risk. Some instruments are riskier than others. The level of risk does not define gambling.

    When you walk into a casino and bet money on roulette, what are you buying? You are buying nothing more than a fleeting chance at winning more money. It is entertainment by thrill. There is no tangible thing that you own from gambling.

    Investing is one way that companies can raise capital to expand their business. Business expansion can lead to greater employment and higher standard of living. For investing to work as an economic system there must be liquidity. Someone must be willing to buy your financial instrument later at a higher price or some town must still be collecting taxes to pay back your bond years later.

    Hopefully you can see now why investing is encouraged and supported in society and gambling is either illegal or merely tolerated.
