What is the opinion that David Ellis has about technology

Shown below is the start of a coding region within the fist exon of a gene. 5'--3' 3'--5' how many cas9 pam sequences are present?

Write a fragment of code that reads in strings from standard input, until end-of-file and prints to standard output the largest value. you may assume there is at least one value. (cascading/streaming logic, basic string processing)

Suppose a cpu with a write-through, write-allocate cache achieves a cpi of 2. what are the read and write bandwidths (measured by bytes per cycle) between ram and the cache? (assume each miss generates a request for one block.)
