A Vigenère cipher uses a sequence of "shift-by-n" simple substitutions, where the shifts are indexed using a keyword, with "A" representing a shift-by-0, "B" representing a shift-by-l, etc. For example, if the keyword is "DOG," then the first letter is encrypted using a simple substitution with a shift-by-3, the second letter is encrypted using a shift-by-14, the third letter is encrypted using a shift-by-6, and the pattern is repeated—the fourth letter is encrypted using a shift-by-3, the fifth letter is encrypted using a shift-by-14, and so on. Cryptanalyze the following ciphertext, i. e., determine the plaintext and the key. CTMYR DOIBS RESRR RIJYR EBYLD IYMLC CYQXS RRMLQ FSDXF OWFKT CYJRR IQZSM X

I'm taking a class on how to make a movie, and it offers some apps that would be in the process. the thing is, i don't have any of those ha. if you have any tips on some apps i could use, that would be awesome. i don't have an iphone, so don't suggest any apps like imovie. i know that this is a weird question, but it would be super for me. : )

1. so if i wanted to build a linux server for web services(apache) with 1cpu and 2 gb of memory.-operating at 75% of memory capacity2. a windows server with 2 cpu/ 4gb memory- operating at 85% of memory capacity3. a storage server with 1 cpu/ 2gb memory- operating at 85% of memory capacityhow much memory do i have to add for each server.so that the utilization rate for both cpu and memory is at a baseline of 60%."the details for the cpu like its processor or the memory's speed isnt to be concerned" yeah i kept asking my teacher if he's even sure about the but the whole class seems to be confused and the project is due in 3 days..this is a virtualization project where i have to virtualize a typical server into an exsi hypervisor.
