   I think this is a typical response for someone with aphantasia. To see why your take might be false, many people dreams have a fidelity of images that is comparable to reality, even for people with aphantasia. Do you dream with this fidelit

   I've only skimmed the article but it seems to relate memory with aphantasia, which I haven't heard before. I'm a bit skeptical of this take. Note that people aphantasia tend to score better at scene recall, at least in some

   The test is this: Close your eyes and try to visualize an apple. Do this for 30 seconds or so. Try to visualize the skin, the reflection, the texture, the stem, the depth, etc. Try to hold a stable mental picture of that apple. After the 30

   Yes. As a proxy, you can look at storage. The human brain is estimated at 3.2Pb of storage. The cost of disk space drops by half every 2-3 years. As of this writing, the cost is about $10 / Tb [0]. If we assume about 3 halvings, by 203

   O(n^2) where n is what? If it's the number of pixels, you have to touch those anyway, no? Why can't you create blue noise from walking a Hilbert curve and placing points randomly with a minimum and maximum threshold?

   As a programmer, you sometimes want to make an alphabet lookup table. So, something like: var alpha_lu = "abcdefghijklmnopqrstuvwxyz"; Typing it out by hand is error prone as it's not easy to see if you've swapped

    I'm kicking myself for not thinking of the `nato` script. I tend to try to not get too used to custom "helper" scripts because I become incapacitated when working in other systems. Nevertheless, I really appreciate all these

    In general, I think these types of sticky behaviors only change when there's an application that people gravitate towards with the changing behavior embedded. One such candidate is cryptocurrency and personal finances. The cryptocurren

    Nice article! The idea is to make a pleasing "swooping" curve. It creates some number of random points simplex noise [0], sorts them using Hilbert sorting [1], then connects them with a hobby curve [2] [3]. Simplex noise is akin t

    Is there any insight into why it's 0.85 or 1.15, specifically?

    I have a pet theory that the reason why the FT, and other transforms (generating functions, Mellin/Laplace/Legendre/Haar), are so useful is because many real world functions are sparse and lend themselves to compressed sensin

    Ha! This is NP-Complete, no? In practice, it probably doesn't matter but my bet is that there are some configurations that will take exponential time to see if the player should be "forgiven".

    No. I may have a guess of what the intended license is but what the license says is complete nonsense. It's self contradictory. If they want to let people use it in non-commercial settings but are willing to provide a license for comme

    I've seen it. For some reason, the Vlambeer one really hit home for me, whereas that one fell flat. It's not that they're saying fundamentally different things, it's that the Vlambeer one shows it better.

    For me, the "owl" was all the polish and game feel. "The art of screenshake" by Jan Nijman of Vlambeer [0] was what helped fill in the steps to "making the owl". I think most people with reasonable know-how can

    I sort of agree with you but watts are an instantaneous measurement and is essentially a derivative. `Wh/day` is effectively doing the integration and giving a term for "energy usage per day", which I find much easier to thin

    The 250 W/m^2 is measured sunlight, not the amount reflected by the atmosphere. I absolutely would not confine ourselves to land as oceans provide a large area available for solar energy capture and there's no reason to think we m

    For context, a back of the envelope calculation is: * Solar energy (on earth) gives about 250 W/m^2 [0] * Earth has an approximate radius of 6.371 * 10^6 m * Estimating sunlight on a disk of earth's radius yields ~ 700 * 10^15 (Wh

    I feel like the Monte-Carlo simulation modeling trick is one I picked up intuitively but only recently heard formalized. Do you (or anyone else) have a list of example problems that are solved in this way? Like a compendium of case studies
