Time for #PapersThatMakeYouGoHmmm! A weekly summary of new ML papers from arXiv that make me think one or more of:

1. That looks useful!
2. That's an interesting approach!
3. A business could be built around this!
4. How did they do that?!

The interview with CNBC of @chamath is a much watch because there is so much insight hidden underneath.

There are many things that caught my attention. The one thing was the abstraction that hedge fund strategies are all 'momentum' plays. What it seems to imply is that the marshaling of resources at an opportune time drives the future behavior of a stock.

From basic physics, we know that momentum is mass times velocity. So any 'momentum' tactic employs the variation of mass, velocity or both. Wrt stocks, mass is money and velocity is speed of trade.

We cannot argue that there are benefits of scale associated with having more money. Also, high-frequency trading has shown the value of high-speed trading. So in an abstract sense, market manipulation can involve a kind of momentum play.

The objective of stock trading is to buy a financial instrument at a low price and sell it at a higher price. The purpose of a momentum play is to front-run the decision process of other traders such that one acquires the assets before a decision is made.

Piper Alpha was an originally designed as an oil producing rig in the North Sea approximately 120 miles North East of Aberdeen, Scotland. It was a fixed leg platform in water depth of 475 Feet of water. The installation sat close to 275 Feet above water to the top of the derrick.

2) It started production in December 1976 for OPCAL joint venture. OPCAL being Occidental Petroleum Caledonia, Texaco Britain, Thomson PLC, and Texas Petroleum LTD. Occidental was the majority stakeholder at 36.5%

3) Occidental being majority stakeholder took control of technical and operational duties with running and operating the rig. When oil production started in 1976 it started with a flow of 250,000 BBL/day and eventually increasing this amount to 300,000 BBL/day.

4) 300,000 BBL/day would account for approximately 10% of the UK’s oil production at the time, so needless to say it was one of the most important rigs in the area. Any gas that was flowing would be flared or consumed by gas turbine generators

5) Around 1980 there was a decision to convert the rig to also process gas along with the oil. This was a major conversion, and if it would have been scoped in from the beginning, most likely construction of the rig would have been more accommodating for gas.

WTO e-commerce #digitaltrade consolidated draft leaked by @bilaterals_org Some interesting things (1/n)

(2/n) Intermediary liability is included without brackets, normally meaning there is some agreement. The text is based on US proposals but has more extensive caveats and exceptions than existing US trade deals

(3/n) No agreement on cross-border data flows at WTO #digitaltrade consolidated text

(4/n) FWIW The UK's (and US) position on WTO #digitaltrade exceptions to the liberalisation of cross-border data flows vs the EU's. Guess which one is which

(5/n) Financial data may be included in the ban on forced localisation of computing facilities, but with many caveats. US regulators had pushed against this in the past but they seem to be losing the battle. Several alt texts. UK to bring more proposals.
