'Attacker' profits –$350k using flash loan and shorting on Ethereum

This thread once again proving that no one defines their acronyms on first use. The twitter thread reads like gibberish. What is bZx, who is dydx, what is a WBTC, what does "half~ half" mean, what is uniswap? is this $350k? or is it 350K cryptocoin equivalents?

Oh and btw, the title says -$350k, but the thread says ~$350k. But what's 700 thousand dollars between friends.
