   Thanks for the suggestion. I'll try B&H next time.

   I will concede that Amazon immediately initiated the refund process without hassle. And yes there is a statistical question, which is why I'm asking other users what their experience is like with other retailers.

   > But, at Jane, SBF osmosed another trading principle. He learned to be “risk-neutral”: In simple terms, a trader, given a choice between $50 and a 50 percent chance at $100, must be agnostic if they want to maximize the expected value o

   But you actually can make money honestly by finding mispricings in the market. Eg Buffet, or Burry during the housing crisis. You can also make money through arbitrage or other brief financial blips that occur in the market. These things ar

   How can the provable solvency scheme possible prove solvency for fiat holdings? For example, I deposit $100 into the exchange. How can the exchange prove to me that it hasn't gone and gambled that $100? I think this could only be handl

   Curious if anyone actually agrees with the supposed benefits of scroll hijacking. I find it jarring and always hate this effect when I come across it. > Scroll canceling enables you to animate objects that don't scroll with the page

   This tidbit about a prodigious undergraduate struck me. He double majored in math and physics and was about to start his PhD at Harvard. And in a sudden freak accident he was gone from existence. The universe will always remain unfathomable

    I believe that the language designers did some experimentation and designed the vtable struct so that calls to it can often be devirtualized. See this blog article for more details https://pithlessly.github.io/allocgate.html

    Looks like its advocating for a modeling language like UML, except it's based in category theory. The advantage is that you can formalize certain heuristics to help you quantify if your architecture is consistent and simple. You can al

    Looks like they made a version that scatters images of everything except trousers! Unfortunately, they hid the results at the bottom of the supplementary pdf [1]. [1] https://static-content.springer.com/esm/art%3A10.118

    This story is especially interesting, given the discussion happening over at the thread about a developer Tornado Cash being arrested. https://news.ycombinator.com/item?id=32436413

    The dev doesn't operate the TornadoCash contract. The code is actually run by people who operate ethereum nodes. After the initial deployment, the dev has zero involvement.

    I agree. Zig is great in many ways but I am also so frustrated by some of the obviously horrible unergonomic decisions the core team makes. To this day, you are forced to declare loop index outside the loop body, despite many requests from

    The material might actually help. I'm guessing that as you slide the blocks against each-other, friction melts the surfaces. When the blocks settle, the surfaces re-freeze, gluing them together.

    Your questions prompted me to skim through Walter Block's exposition of evictionism [1]. There is a sense of what constitutes a reasonable, gentle, eviction. "From these examples is derived the principle that when one evicts a tre

    This line of thought has been elaborated under a theory called evictionism [1]. Evictionists concede personhood of a fetus, but reject its right to reside in a womb without consent of the owner of the womb. The logic seems sound, but leads

    I think you're getting at only half of the idea of a database engine. The other half is to provide a flexible querying interface to slice up and aggregate the data into reports. The user may be willing to tolerate some inefficiency in

    There are built-in tools in rec for querying, joining / foreign keys, checking data integrity against a schema, and aggregation and reporting. So the set of advantages over json/yaml are similar to SQL's advantages, except th
