    I'm not sure how that would work out, you might just end up with wild yeasts in your supply. You would likely be interested in how sourdough starters are made.

    To add to this thought, it may be interesting to consider an expression as a CAS would - a tree of functions with inputs. The evaluation would then be the post-order traversal of the tree.

    Since this is an equivalence class on the limiting value of infinite sequences you most likely will not be able to recover that kind of information. This type of mapping is not bijective. The most that you gain is knowing that there is some notion of "the result of this proof is computable."

    If you see my reply it's not so tedious, but not much is gained. It might be interesting to see how far you can get with computable numbers, but seems like this was wrong.

    I think that constructing the reals is a general consequence of asking how you might be able to approximate the results of x*x = 2. Consider the sequence where the nth term takes an approximate answer for x up to n digits. This is a Cauchy sequence with a limiting value of √2. If you construct all Cauchy sequences on the rationals and take the equivalence class where the limiting values are equal you get the reals. Some of those Cauchy sequences are certainly equivalent to computing some number where the nth term in the sequence is the nth step of computation of a more accurate answer. It doesn't feel very natural to work in a set of numbers generated from a subset of all Cauchy sequences on the rationals, unless a property of those numbers (in this case computability) is useful. In fact it's trivial to construct all computable numbers by doing what I just suggested, but I don't see what is gained.

    Edit: I should point out that these are not really Cauchy sequences, but only because we're still working in rationals and haven't defined real numbers and as a result cannot use the standard definition of a metric space. If you make a special version of metric spaces using rationals it's enough to get you to constructing the reals in this way.

    The point of constructive proofs in my view is to provide structure to work from, and build intuition about concepts that are not intuitive in other forms. It is trivial to construct the reals using a technique similar to metric spaces, as mentioned elsewhere in this discussion. The reason reals are used is because once you get to the rationals it's natural to ask what x*x = 2 is.

    A bit of an unusual suggestion, but have you considered Hitchhiker's Guide to the Galaxy? A book does not need to be philosophical or dense to have characters that can be deeply examined. I'm recommending this because it's short, fun, and if you've never had the desire to read a book this one will keep you interested.

    This isn't no-money, rather low money, but you can look at local cafes, coffee shops, bars, and other places that host shows for local bands or open mic nights and head there for a few hours. It's really fun to check out what the local artistic scene is like, and you meet tons of extraordinary people that way. I would recommend going and watching an open mic at a coffee shop if there are any around you - usually it will cost you a coffee or two for a table, but the environment tends to be relaxed and accepting of whatever is presented. If there's an actual show scheduled for the place you might expect a few dollar cover charge, but that's usually it.

    Here are a few lesser known ones that I think are interesting:

    Broken Bride by Ludo

    A man's wife dies in an accident, so he invents a time machine to try and travel back in time to save her. He ends up travelling from the prehistoric past to the far future due to problems with the machine.

    Seven Horses for Seven Kings by Black to Comm

    YouTube is an awful place to listen to this, I would recommend using another option if you can. This is chilling to listen to, and I haven't talked to anyone who hasn't felt dread while doing so. Worth a listen if you have an hour of time to sit down and take it in.

    Here are some more well-known ones that are phenomenal in their respective genres:

    The Rise and Fall of Ziggy Stardust and the Spiders from Mars by David Bowie

    The story is more or less what's on the tin. In my opinion this is probably one of the best albums ever released.

    Immunity by Jon Hopkins

    A phenomenal record that details a night out. Also it's techno/house.

    Since I Left You by The Avalanches

    Not linking this one, since I can't find a link to the Australian release (the original) which has different samples than other releases. If you're going to to listen to it, find that one. I've always interpreted this as someone being harshly broken up with, falling into a slump, then getting up and travelling the world. The end to this journey is realizing that nothing has changed about their life, and they're still in the same place they started at.

    I will say that is one of my least favorite songs from the album, but I chose to recommend it due to those lines in particular. I had to search for something as succinct and catching as this. Another thing to mention is that this artist's flow is a bit unorthodox, and on first listen a bit... jarring? It's hard to describe, but I think the style fits the lyrical content of the album.

    More Thoughts I usually find that Wood's lyrics are packed with meaning that exposes itself under closer examination. The themes in this album are expressed wonderfully, and the work as a whole outshines any individual song from it. I highly recommend giving Spider Hole and Houthi a listen, then skipping to Red Dust for an example of the complex self referential lyrics and themes of isolation, poverty, fear, and violence the album demonstrates.

    More excellent resources! One of the problems with the Model 3 is that I won't get the same discounts due to high demand and lack of dealers. Not to discount the other issues that currently exist in my case with electric vehicles, but the 2019 UX Hybrid is on that list because I can get a deal on it - the new model year is out, I have offers on other vehicles, etc.

    This is excellent data, thanks a ton! I've since added a 2019 Lexus UX hybrid to my list of interest, since its MSRP is similar to the other vehicles I was looking at. It's good to see that Lexus and Toyota have such high reliability. I would absolutely go for an electric vehicle, but the area I live in and long range driving I tend to do are not conducive to owning one. I will probably get one as my next vehicle.

I would prefer to not have to worry about catastrophic failure of some system early in the life of the vehicle. One of the benefits of the Toyota was that it seems to hold value wery well, but I haven't checked the Nissan.
