    1. S-procedure

      Just a minor remark on the terminology:

      Historically, the result known as S-procedure was related to quadratic functions (as discussed, for example, in Sec. 2.6.3 of the freely online available Boyd, Stephen, Laurent El Ghaoui, Eric Feron, and Venkataramanan Balakrishnan. Linear Matrix Inequalities in System and Control Theory. Studies in Applied and Numerical Mathematics. Society for Industrial and Applied Mathematics, 1994, https://web.stanford.edu/~boyd/lmibook/).

      The extension to SOS polynomials is (perhaps better) known as Putinar’s Positivstellensatz (as discussed, for example, in Sec. 2.4 in J. B. Lasserre, An Introduction to Polynomial and Semi-Algebraic Optimization. in Cambridge Texts in Applied Mathematics Book, no. 52. Cambridge: Cambridge University Press, 2015).

      It may help readers when searching for some more info in the literature.

    1. Since using case insensitivity is so widespread, take their sign up email address and make it lower case. Whenever they try to log in, convert that to lowercase as well, for comparison purposes, when you go to see if the user exists. As far as sign up and sign in go, do a case insensitive comparison. If the person signs up as Steve@example.com, you'll still want to allow them to sign in later with steve@example.com or sTeVE@example.com.
    2. But you should also keep track of the email address that they signed up with in a case sensitive fashion. Any time you send an email to them, be sure to send it with that original casing. This allows the email server to handle it however it feels like it needs to. So even though the person may always be signing in to your site with steve@example.com, if they signed up as Steve@example.com, you'll always send email to Steve@example.com, just to be safe.

    1. In Hamlet on the Holodeck, Janet Murray argues that digital environments have four essential properties. They are procedural, participatory, spatial, and encyclopedic. They are procedural because software is an authored set of procedures, which can be used to “write rules . . . that are recognizable as an interpretation of the world.”[2] Her focus is on storytelling, but we will see that any piece of software can be seen as an expressive, rhetorical model of a system. In addition to being procedural, digital environments also invite participation in that their rule-based behaviors are “responsive to our input” and they also “represent navigable space.”

      Could be of interest to bring back Kitchin and Dodge's understanding of code/space to this discussion.
