    1. How many methods are there in the arithmetic method category of the CharacterSequence class?

      There are no messages categorized as arithmetic in String but in CharacterSequence, which String subclassifies. Squeak Strings on the other hand, implement arithmetic messages, exactly those mentioned in the solution to the exercise; Note however that String allMethodsInCategory: #arithmetic in both Cuis and Squeak include a seventh method #raisedTo: because #allMethodsInCategory also looks up for inherited methods from superclasses. Yes! you can raise the empty string to the power of n for n ∈ Number and the result is another empty string! WAT :) The fact that we can evaluate '' raisedTo: n without error seems like an unforeseen consequence of #adaptToCollection:andSend: relying on #collect and how the latter works on empty collections.

      See this thread in the Squeak-dev mailing list

    1. Tried to buy keyg at its 90% off sales price but no matter what payment method I choose I keep getting a "Due to processing fees the minimum amount is 100 cents."I'm trying to figure out if there is any way around this, and if not then why can you list a game at a price below $1 if it isn't actually possible for it to be bought at said price?

    1. Couldn't find on Steam. https://steamdb.info/app/793300/ claims that it is there, but https://store.steampowered.com/app/793300/?curator_clanid=4777282&utm_source=SteamDB just redirects to home page.

      Don't redirect to a different URL, esp. without a message explaining why it did so instead of keeping me on the page that I request. That's just incorrect behavior, and a poor UX. Respond with a 404 if the page doesn't exist.!

      That way (among other things), I could use Wayback Machine extension to see if I can find a cached version there.

      But even that (http://web.archive.org/web/*/https://store.steampowered.com/app/793300) is saying "huh?" so I'm confused.

      Where did it go and why?

      I guess it's no longer available, because this page says:

      section_type    ownersonly
      ReleaseState    unavailable

      ... but why?
