Recently Executed Contracts with Issues in EIP 1884

Background

EIP 1884 is set to be implemented into the upcoming Ethereum 'Istanbul' hard fork. It

• increases the cost of opcode SLOAD from 200 to 800 gas
• increases the cost of BALANCE and EXTCODEHASH from 400 to 700 gas
• adds a new opcode SELFBALANCE with cost 5.

OP_CHECKDATASIG

OP_CHECKDATASIG and OP_CHECKDATASIGVERIFY check whether a signature is valid with respect to a message and and a public key. The message is restricted to exactly 256 bits, if longer messages are to be signed, it is recommended to sign the messages hash.

OP_CHECKDATASIG permits data to be imported into a script, and have its validity checked against some signing authority such as an "Oracle".

OP_CHECKDATASIG and OP_CHECKDATASIGVERIFY are designed to be implemented similarly to OP_CHECKSIG [1]. Conceptually, one could imagine OP_CHECKSIG functionality being replaced by OP_CHECKDATASIG, along with a separate Op Code to create a hash from the transaction based on the SigHash algorithm.

The Story of NPM and Yarn

In the beginning there was NPM, and for a time it was good. Packages went forth and multiplied. The New Gods proclaimed the great demon Dependency Management had been slain. But The Old Gods knew better, for they had seen much and knew that the demon can never be killed, only held at bay.

The Old Gods were ignored. In the folly of a young age grew an abundance of packages and with them grew the scourge of dependency. In the depths beneath the earth, in a place beyond memory, the great demon stirred.

The first sign something was wrong was non-deterministic package version mismatches. “This is fine!” The New Gods declared. “A temporary setback, nothing more! We can fix it.” And so they introduced shrinkwrap, a lamp to combat the growing darkness.

But it proved to be too little, too late, and dusk continued to fall. The New Gods suffered their first major defeat at the [Battle of Left-pad](https://www.theregister.co.uk/2016/03/23/npm_left_

A top-down look into Elixir (for Rubyists)

• Phoenix (as "Rails for Elixir")
  • Rails and Phoenix can get suspiciously similar
  • A code sample:
• controller.rb
