All our dreams can come true, if we have the courage to pursue them.

ECS154A Lecture: FISC ALU & mux

• [>] questions to ask later during discussion
  • When to use tab characters vs space (e.g., fiscas help message, print listing)?
  • It is unclear whether bnz disassembly (fiscsim) should print hex or decimal, but I went with hex. Is this expected?
  • Is it expected behavior for all errors to be printed to stderr and cause the program to exit with code 1?
• data path: enables flow of information within/without the CPU
• bus
  • notation: path with a line segment through it, with the bus width (in bits) marked at one end of the segment
  • notated at the ports / pins of a chip
• For FISC, instruction memory is conceptually ROM — read-only memory (doesn’t get modified during program execution)
• standard notation for memory size: $\text{number of cells}\times \text{cell bit width}$, e.g., FISC IM is a 64x8 memory.
• ALU: arithmetic logic unit

Simpler ALU’s multiplexer to showcase truth table & expression of mux:

$$y=\neg op\cdot x_0+op\cdot x_1$$

• when op = 0, use $y=x_0$
• when op = 1, use $y=x_1$

$o{p}_1$	$x_1$	$x_0$	$y$
0	0	0	0
0	0	1	1
0	1	0	0
0	1	1	1
1	0	0	0
1	0	1	0
1	1	0	1
1	1	1	1

SOC001 Lecture: Socialization

Note to self

Stop going to the lectures in-person. Lecturer’s microphone not working all the time + speaker earrape = nah.

• sociological perspectives (notes from participation assignment feedback)
  • conflict
    • note that Conflict is a macro-level sociological perspective, so focus on larger groups and patterns within society, rather than the individual level (e.g., couple fighting)
    • be specific, i.e., don’t say “sociologists focus on inequalities”, “say sociologists study inequalities between genders, classes, races, etc”.
  • functionalist
    • the Functionalist perspective is macro-level; again, focus on larger groups
    • def latent functions: functions that are not immediately obvious
      • having children - manifest function, heteronormativity (the perception that heterosexuality is the normative for relationships) - latent function
  • symbolic-interaction
    • micro-level (interactions that happen on individual levels), but still need to focus on relationship to society (so this perspective woulnd’t focus on how, say, an individual’s personalities would affect relationships)
    • e.g., how different social conventions and symbols are given different meanings by different groups
• Fake Famous (documentary)
  • both the users (influencers) and the social media platform are incentivized to keep bots on the platform
• defining self
  • in a psychological view, self is the part of an individual that is stable and enduring
  • in a sociological view, self is social and fluid
    • reflexivity: continual reexamination and modification of self
    • interaction shapes self
• development of the self
  • Cooley: looking-glass self
    • self is formed by how you think other people think of you
  • How did we come to adopt others’ views of us as self?
    • Mead conceptualized a 3-stage process to learn role taking (taking the roles of others) during primary sociolization
  • Mead self-development stage
    • stage 1: preparatory
      • imitating the people around us
      • no ability to interpret how others see things
    • stage 2: play
      • taking on the role of another (e.g., in a pretend scenario, such as a child acting like a grown-up in a dress-up)
    • stage 3: game
      • taking perspectives of several others simultaneously
      • learn about the generalized other: internalized expectations of commnity
      • Develops the self. Self is social; it is both the subject and object (I, the agent, observes the self)
