Cars are optional and aren't even the fastest way to get around (public transport + taxicabs + bicycle/e-bicycle is fastest). Rent can be low as well, depending on where and how bi…

According to the paper, there's a decrease in demand by the primary home device for activities trackable by comscore. This is the data used (not technically an assmption). I do not…

It does not. Dataset is from comscore, see the comscore website, and comscore is unable to track the click-stream of native apps. If it did, that would raise many security issues.

The study measured primary home device use based on click-stream data from comscore. This requires interpretation with the following considerations: - The dataset they used is from…

--- Western diet is associated with poorer inhibition of wanting for palatable snack foods when sated T.N. ATTUQUAYEFIO1, R.J. STEVENSON1, R.A. BOAKES2, M.J. OATEN3, M.R. YEOMANS4,…

While there are other plausibilities, this agrees with a food addiction model of overeating.

Couldn't figure out a way to solve them reasonably (and within schedule) using RethinkDB, so I did a "master-slave" with the RethinkDB as the master and PostgreSQL as a slave repli…

The capabilities and performance of graph databases do differ, and many aren't cheap, nor well known, so if you need one, you'll need to shop around. Btw, Neo4J is definitely a gra…

Besides multi-document transactions, I've encountered these problematic use-cases (something I discovered after scope creep of projects): 2. When I needed "more exotic" data types …

The most common and relevant difference is that a graph database has a storage engine that is optimized for graph traversal. For example, in a RDBMS, another row is referenced via …

Here's a partial answer: You gain some, you lose some, but in different things. There's a tradeoff, e.g. automatons can do things a lot faster/cheaper, at the expense of "creativit…

It could be depressing as well, since the described effects correspond to the erosion of many important public institutions (like democratic governance). Seems like this decade is …

I read the book (Amusing Ourselves to Death), and I would recommend it for these reasons: - It explores a contemporary topic of significance. Relevance will depend on your interest…

the license also undermines the legitimacy of the ruling party without reducing the spread of information and propaganda that goes against the ruling party - these tend to arise fr…

You ask: 1. Is X good? How is it good? 2. Is it entirely separate from reality? While you might think of it as a simple question, you asked it in the general sense, without any con…

Covers the same thing with more technical jargon, but much more accurate and insightful: http://www.scientificamerican.com/article.cfm?id=time-crysta... EDIT: A lot of comments app…

On the other hand, the investment in [Startup X] is partly justified by the idea that spending money on "10x" talent is a chance for "100x" returns.

I wouldn't generalize this way. P( Y | X ) != P( Y ). X: Hired by google, good grades, good school. In fact, it doesn't test the difference between institutionalized tertiary educa…

There are many sources of competitive advantage, which includes but is not limited to good hiring practices and the development and retention of talent. Companies which were not de…

why should desires just before death take precedence over desires during the prime of life?

I used to use Racket in production and prototyping (few years ago), as a "glue language" and "business-logic" for a web-app, for the parts that are not IO, memory, compute intensiv…

I once did an Ant to Maven conversion job on around 10 mature projects I didn't code. So that a large enterprise can move over to Maven and reap the productivity benefits. Various …

Perhaps your economy won't recover to its former glory, like the way Japan's didn't. Then you'll have at least one first-hand empirical data point, even if you're unable to learn f…
