DEXchain

Presenting a bitcoin sidechain with on-chain utility of hedging price risk of future coinbase cashflows for bitcoiner miners.

Futures Contracts

Futures contracts are agreements to buy a specific commodity or asset at a specific price and time in the future. Since the actual transaction does not happen until the settlement date, the buyer does not have to pay the seller until that time. At the end of the futures contract, the buyer must pay the seller the agreed upon price, and the seller must "deliver" the commodity to the buyer.

However, before delivery time, the buyer (or seller), can close the contract by selling (or buying) to somebody else. Assuming the price of the futures contracts trade relative to the underlying commodity, these can be used to hedge risk in the underlying commodity, or to speculate with leverage.

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real
