Good catch. Too late to edit the comment. Yes, I meant C.J. Date's "Introduction to SQL". I was trying to get a link to the latest edition which appeared to be the 2nd link on an Amazon search for "Date introduction to S

Chris Date's Introduction to SQL [1], or Edgar Codd's last book [2]. Actually both are worth reading to discuss differences in philosophy (e.g. "no NULLs" vs 4-valued logic including "unknown" and "not app

It gets more interesting with branded goods which are completely fungible. In theory they have a global MSRP or at least a globally optimised one, to avoid arbitrage, and brands get pretty advanced in fighting the grey market (for example,

EntrePass has been catch 22'ed a few years ago. In order to even apply, you need to have investment from a limited list of approved investors. On top of that, you need to hire a certain number of people within a certain amount of time,

This definition of selfishness (which I agree is the most consistent) was strongly associated with Ayn Rand's [1]. Having grown up in Europe, reading her works was quite a shock. The only thing I'd add is that in my experience &qu

It's very simple in Singapore too, arguably simpler. You go to the Small Claims Tribunal (you can get a date within days, anecdotally), the Registrar decides the claim in a few minutes, and it costs you a total of 5 quid to file the cl

Are you sure about the rent? I rented a 2 bedroom, with windows on 3 sides, next to a park and public transport, and a large balcony with BBQ, for 2 months (so short term let, higher rates), 20 minutes by tram from my office near Seefeld, f

This is a common dilemma in finance, the key is the possibility of outsized returns made possible with leverage. Let's say you have done well at your bank for the last X years and you have an audited track record somehow and a decent a

I had a really shameless colleague who flew to London twice a week. He never checked in luggage, stayed in his suit, and arrived at GVA about 20 minutes before flight departure. If there was no queue, he'd make it easily; if there was

Having done ZRH-GVA many, many more times than I care to count in both directions, may I recommend the plane. The flight itself is REALLY quick and very scenic, even (especially?) at night with the moonlit snowy mountains [1], which are to

I should be more specific: this applied mostly to Grab, an Uber competitor (the South East Asian Lyft if you will), in its early days before it implemented its own surge pricing (which is invisible - the price changes upwards, but is quoted

In Singapore, drivers told me to put a guaranteed tip in the "notes" section when it's difficult to find a driver, as many people add 5-10 dollars that way and get picked up first. Personal surge is also what came to mind rea

That's not quite my argument. It's subtler than that: 1. the world is not univariate and there is rarely one variable that explains 90% of the variation; 2. each user has a different utility function and it is rare to find one tha

My impression has always been that drinking aged whisky was more about signalling (both financial status and knowledge and taste), including in the largest markets (France, etc.). Same reason people still wear suits and Goodyear-welted leat

I had to do it with one client. My philosophy is one of automation and never doing something twice - the less hours the client needs per unit work done, the better - and the philosophy of some of their managers was the opposite, that you di

I guess so. Retaliation is the best strategy in iterative PD, no? (I'm rusty on this stuff). Nash equilibrium in a regular PD would be DD, but it assumes that the other side will defect. I think from experience that the payoff grid is

Brilliant marketing: 1. get people worried about something they previously didn't care about; 2. as a solution, add a new part to the car that will need frequent replacement and maintenance, thereby increasing the CLV.
