Recap
Binary
- something that can be turned off or non
- Adding an extra bit multiply by 2
- 2^3 = 8
Ada Lovelace
- First programmer
- Found that the formula could solve multiple equations and tasks
Variable
- Algebra
- Store something in a character and recall and iterate upon it
- X + 1 = 2
o X + 2 = 3
HTML, CSS, JS
- Html describes content
- CSS makes it look
- JS interactions it take place (a preloader leading to a page)
o Hovering over a button, the button lights up etc.
Semantics is language that describes content
Analysis
- Detailed examination of the elements or structure of something, typically as a basis for
discussion or interpretation
Analytics
- The science and use of analysis
- Google Analytics used to implement analysis
Big Data
- Yale Library in 2040 will have approximately 200-million volumes
o Thought of physical volumes back in 1944
o But phsial spaes do’t sale ell
- When you digitize something, the amount of space is minute
o Now its scalable and you can store more content

many bulbs should be added

- Google, Facebook have decentralised exabytes
BIG DATA: 3 V’s
- Volume, velocity and variety constitute big data
- If I have a petabyte of customer data, theres a lot of volume, and it doubles every year so
you have velocity
o When you have data from different sources coming together what are issues?
They may not be compatible (linux, mac, and windows) because they
came from different sources and are formatted in different ways
Need to massage information and data
Problem by sorting by date?
o It changes as you modify the file
BIG DATA infographic
#Panamapapers
- move money outside country so they would not pay taxes from those that are wealthy
- Mom = the government in Panamapaper videos
Why are the Panama Papers a big data problem?
- Size of data breach is a volume breach
o The more clues you follow, the greater the data will expand
- If you find a right shade of lipstick, many women would wear it and find data for
geolocation, look at camera footage, conduct interviews
o All this is adding data
- If you have >1 tb of data, each document is a clue you have to follow and it becomes
exponential in terms of volume
- Variety of data
o Associate shell companies with main companies
Shell are connected to lawyer etc.
