    Congratulations! Being a (part-time) youtuber myself, can I ask what you are using for audio? It is indeed great!

    I mean to function without being babysat, not (only) from an economic perspective. I'm not suggesting in any way a class-based education system, which are awful. I'm simply stating…

    Giving everyone the same chances is a principle pretty much everyone reasonable agrees with. What I'm saying is that if you are poor, your best bet is to choose to pursue whatever …

    It helps to first discuss what the purpose of the education system is before trying to reform it. In my view, the purpose should be: - enable each individual to function independen…

    This is great and very useful to me! What source are you getting the channels from? And how do you choose which channel goes in?

    I would like to draw the attention to the precise wording around the statistics: """ In 1970, just 1 in 5 U.S.-born PhD graduates in economics had a parent with a graduate degree. …

    I use it for small video processing. It is better than openshot in my experience in terms of stability. The interface is reasonably good, with the exception of cropping, where you …

    Perhaps you could have channel owners register their channel if they want to be indexed. That would be super useful.

    Nice! Is it possible to do it without fixing the channel?

    As an amateur YouTuber myself, this is disconcerting. A real video takes quite a lot of effort to do properly, especially if you try to aim for depth. The guy is obviously smart, b…

    As a (tenured) academic myself, I fully understand the flexibility (and the lack thereof). A staff of 50-100 sounds like a true nightmare. I've experienced classes of ~500 students…

    It is unfortunate when a talented teacher, as the OP seems to be, turn to industry for (significantly) more money, but this seems to be the way the market works pretty much everywh…

    Almost: +13 would be rewritten to ((()))+(((13))) and -13 to ((()))-(((13))). If you interpret the empty expression as 0, perhaps it would work out. Good question!

    Some context for puzzled readers: This site uses combinatory logic ( https://en.wikipedia.org/wiki/Combinatory_logic ). Combinatory logic is a way to express logic without using va…

    It seems to be fixed now. It would be fascinating to read an analysis of what exactly leads to the bug.

    Does anyone know what technology is used underneath? It is obviously compiled to webgl, but what are they using for development? Unity? Some other engine?

    There are around 20 persons credited at the end, so that should give a rough estimate. It is quite well done. Animation and graphics is quite expensive to develop, since iterations…

    I would not say they are on the way out, but definitely out of the mainstream and growth is limited in this space. I would say the same is true of podcasts to a certain degree, wit…

    Having lost ~75 pounds and having (mostly) kept it off, the "trick" is to stop eating certain foods, sleeping well and exercising. Start by avoiding any sugars whatsoever (exceptio…

    This is called bisection search (search for the largest/smallest value satisfying a given predicate). It also reminds me a little bit of exponential search (upper bound unknown), a…
