@rossium The first time I tried to solve this (a friend had it for homework in undergrad) I reasoned that starting from point n you have 100% probability of reaching 0 or 2n, each equally likely. Thus a 1/2 + 1/4 + ... + 1/2^n chance of touching zero before 2^n.
@JAWA6972@RCMaxw3ll If his chosen field is UX, I'd guess a more certain problem is that there aren't jobs in it and it doesn't really require 6 years of training. Say you wanted to make a phone app or web app. You wouldn't worry about being outcompeted in UX by guys with a master's in HCI.
@JAWA6972@RCMaxw3ll A large fraction of people with a bachelor's in CS -- I would guess at least a third of those of the safety school I went to -- can't really code and won't work as programmers. So companies have interviews that test if they can really code.
@_its_not_real_@generativist Maybe constant bit rate is enough; was asking because I read blog posts a decade ago. Not surprised Signal mentions CBR (and seems to imply that suffices). https://t.co/p74uFCZSsW
@abdimoalim_ Real analysis actually just makes sense and you should feel increasingly comfortable as the hand-wavey calculus mumbo-jumbo you learned before gets rigorized.
If this is your first proof-based math textbook then that might be the issue.
