This is a message for bullies around the world. 1:12PM 1/25/2021 Dear bullies,

See that girl you just called fat? She is starving herself. You know that girl you just called ugly? She spends hours putting on make-up hoping people will like her. That boy you just tripped? He is abused enough at home. See that old man you made fun of cause of the ugly scars? He fought for our country. See that young boy you just made fun of for always being sick? He has to walk home in the snow cause his family is too poor. That guy you just made fun of for crying? His mother is dying.

Martha is designing a single-player game. her manager suggests that she plan the design to incorporate future modifications. which principle of game design relates to planning for future modifications?

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
