  • adding emails need sequential typing
  • hitting enter should move on to the next page
  • date selection
  • “Monday next week” doesn’t NLP
  • reading calendar output isn’t sorted

bugs

  • reading other people’s calendars isn’t working
  • need some information about that the heck is actually happening on the scheduling
  • show other people’s overall availibliity in the scheduling page
  • idea of “budget”

next actions

  • scheduling multiple people is broken. ah.
  • have the idea of a “meeting owner”, and we only reach out to them to confirm final date + have an ability to add a message (with templates); also allow the message owner to change to alternate schedules on that date
  • the weight number doesn’t make sense—correct alt-text and make the number work

    • somehow remind people after the fact that the meeting is scheduled
    • tie in evite abilities (this will be nice for your party, etc.)
      • event planning built in? type in a budget and find vendors for the party.
      • age range?
  • the weight number doesn’t make sense—correct alt-text and make the number work

home page

  • “the front page looks like that for an OB-GYN” — feels like ZocDoc
  • it is also not that fun
  • maybe some kind of memphis design

scalar multiplication

Last edited: August 8, 2025

Scalar multiplication is the process of multiplying a scalar to an element in a set.

constituents

  • A set \(V\)
  • Some \(\lambda \in \mathbb{F}\)
  • Each \(v \in V\)

requirements

scalar multiplication is defined by a function that results in \(\lambda v \in V\) (maps back to the space!) to each \(\lambda \in \mathbb{F}\) and each \(v \in V\).

additional information

See also scalar multiplication in \(\mathbb{F}^n\).

scheduling

Last edited: August 8, 2025

scheduling is the tool to figure out which thread can run. Because threads exist in different thread states:

  1. running
  2. blockde - waiting for an event like disk, network, etc.
  3. ready - able to run, but not on CPU yet

a scheduler needs to do the task of ordering ready threads to run, moving running threads to ready when it has ran for enough time. Possible pathways:

  1. ready => running
  2. blocked => running
  3. blocked => ready => running

You can’t go from ready to blocked because you have to do something to know you are blocked.

second moment of area

Last edited: August 8, 2025

The second moment of area is a value which—given an origin—describes how point masses are distributed around that origin. (i.e. a number for how point masses are distributed). It is in units \(m^{4}\).

Take, for instance, the following picture:

We have defined an origin at \((0,0)\) of the figure above. Furthermore, we have some \(\rho_{i}\) which is the distance from that origin to each of the infinitesimal areas \(\dd{A}\).

Then, the second moment of area is defined as:
