1. It's possible to connect a keyboard to an iPad/Android tablet. (and larger screens as well) 2. You imply that only a minority of people would be doing "heavy" production work on a computer. The trends seem to be the opposite of that, at

You got it for free - why should you expect more? If there's a demand for accurate, well-supported, and much harder-to-produce news and commentary, which someone is willing to pay for, many journalists would be happier as well. This, howeve

Really depends on your metric of "rate of advancement". If it's going to be about what common people think, then consumer-product and lifestyle innovations would be over-weighted. Viewed by a specialist in any field, that field's progress w

Consumer goods are, however, much cheaper now as compared to 50 years ago (at least in urban Asia where I live). It makes a huge difference between spending 10% of my income on daily necessities, as opposed to 50% like my ancestors did. Arg

However, when working with good type inference (i.e. Haskell)... 1: it's possible to relax on the discipline a little; mental resources are limited (at least for me). 2: typed-based dispatch; refactoring based on static types; etc.

by dingfeng_quek 14y ago
Static types are attractive to me. I haven't tried Typescript for other reasons: 1) I use CoffeeScript for the concise code, which Typescript doesn't have. The trade is a lot of verbosity for static types - verbosity above the static type d

You're not exactly describing the difference. I would say that: 1. We have statistical evidence from large numbers of SIMILAR people with similar tumors. Economic events tend to be highly dissimilar in terms of context (Great Depression? 19

I have to agree. The author hasn't dealt with all the unsolved problems with bounded rationality, which quite frequently involves the inability to compute the future (the case where even if perfect information is available). Then, somehow,

EMH is actually a hypothesis (not a theory) that arises from non-arbitrage models. It's not meant to describe the real world, although it's thought-provoking to look at how "efficient" real markets are, so people like to characterize and "t

While the regulation on GMO labels is evident, it's hard to decide whether GMO is good or bad, and whether it is right or wrong to encourage or discourage GMO. Bacteria in beef is problematic to justify because the bad outcomes tend to be l

I assume you assert that out of ignorance. Modern pesticides are extremely toxic in small quantities, some with immediate and easily observed effects, others with delayed and long-lasting effects. Regulatory limits are often based on immedi

However, genetic differences between certain groups of people can be quite significant. Sometimes, they are clustered geographically, like immunity against malaria. Other times, they are clustered based on a shared history and selection pre

Hi zipdog, when such an article is published, it should (if you're doing real work/research in this area) be interpreted as X is one of hypothesized significant causes of Y. X is often a new finding, or an old hypothesis with new support, o

Java is good for enterprise IT consultancies. It requires a lot more detail to attention to implementation most enterprise app features, yet it still works acceptably in the end, maximizing consultancy fees.

If you restrict writing to only the "sounds" words produce when they are read, good writing should sound like spoken language is still hard to defend. Besides how the brain differently processes words seen from eyes, the varied methods of r

Exactly. I don't think models, math, and simulations in the area of economics are evaluated by their predictive power or their fidelity to the real word. I'd say that they are generally exploratory models and pedagogical models. That's why

Unless we compare simulated models with reality via empirical studies? (: I believe the same issues plague subjects like theoretical physics. Then again, we do have the preference-utility and utility-maximization core of microeconomic theor

Cartel-like (monopoly/oligopoly) pricing leads to a non-optimal outcome (the loss is usually called the deadweight loss). The price is set higher than the socially optimal price - some consumers who would have benefited overall from the goo

The fast ones become rich. They perform trades equivalent to front-running and/or scalping. The enterprising fast becomes a middleman to the slow.

by dingfeng_quek 15y ago
The issue with "cartel-like" price is that it is not the perfectly competitive price, and the perfectly competitive price is the most efficient price - the perfectly competitive price is, in the absence of externalities, the one that brings

LOL is many more times more complex than CS. If you are weird, try running game-theory and stochastic simulation models. Try to optimize things like item builds, team-movement/formation, engagement sequence, allocation of champions to lanes
