Finished the blockchain pluralsight course this week and started on the Github course
Should be done with the Github course by tomorrow
Watched Hell or High Water, the movie was really good and I especially like the music. The music is by Nick Cave and Warren Ellis and it's I guess Western music?
Started to listen to the King of Kings podcast from hardcore history, I think this is the third time I am listening to it. Such great stuff!!
This Week I Learned
Merkle treeWhile watching the Pluralsight course Blockchain Fundamentals I learned about a Merkle tree
In cryptography and computer science, a hash tree or Merkle tree is a tree in which every leaf node is labelled with the hash of a data block and every non-leaf node is labelled with the cryptographic hash of the labels of its child nodes. Hash trees allow efficient and secure verification of the contents of large data structures. Hash trees are a generalization of hash lists and hash chains.
The concept of hash trees is named after Ralph Merkle who patented it in 1979

White Plague
Heard about this on the Lore podcast episode 77. White plague is also known as consumption or tuberculosis, never heard it called white plague before. Tuberculosis I know very well, my grandfather died from it, he was 23 years old and when he died my father was only a month old. It was a rough time for my grandmother having to raise 3 kids on her own in the 1950s past war time frame.
Iron
Heard about the different kind of iron on the How it began podcast episode: Mastering Metals: From Sticks & Stones to Cars & Computers
Wrought iron... this is produced by putting the rock on a fire and then manipulating the iron by banging on it
Cast iron... this is produced by using ovens and melting the iron.. it is however brittle
Steel... this is produced by removing carbon and it is not brittle like cast iron
This Week I Tweeted
A Vast, 430-Year-Old World Map, Full of Places and Creatures, Real and ImaginedThe map shows a lush, highly personalized take on the world, with a surprisingly large collection of real and fantasy beasts carousing and cavorting on land and sea. Rumsey’s scan and digital assembly of the cartographic puzzle represents the first time that Monte’s work has been seen in its full glory: It is the single largest world map of the 16th century, and one largely forgotten or overlooked by cartographers and scholars.
Some interesting stuff, would be nice to have this hanging on the wall
