TravelAndFood··on No Cash Needed at This Cafe: Students Pay the Tab with Their Personal Data
Maybe? The point of the system is to profit/ensure no default/etc. So if the system determined criticism actually did make you more likely to default, sure. If not, no.
TravelAndFood··on Approaching Access Control on the Web (Part I)
"Authorization" answers "does the entity have permission to access the requested resource?"

"Authentication" is "is the entity is who it says it is?"

"Entity logging in" is an example of authentication. Is the entity trying to log in the entity it claims to be? An example claimed identity is a username, and example proof of authentic claim is a correct password.

"Entity trying to read data" is an example of authorization. Does the entity trying to read the data have permission to read that data? Checking an access control list against a username is an example of checking authorization.

How are they different, and separate?

I claim to be a user and supply a password. My claim is authenticated and I successfully log in. I have requested access to zero resources and thus no authorization has occurred.

A hacker steals my session while I'm logged in and requests my sensitive data. The system sees the request came from a username that is on the access control list for the resource and authorizes the hacker to see my data. No check on my actual identity (authentication) occurred, only a check whether the provided identity is authorized.

TravelAndFood··on Ethical OS and Silicon Valley’s Guilty Conscience
It seems "Suppose there were a technology X which was going to be invented eventually" is not a very powerful constraint because on a long enough time span, every possible technology is invented. So, this argument explains everything, so it explains nothing.
TravelAndFood··on Behemoth, bully, thief: how the English language is taking over the planet
As a native English speaker who has passable Spanish, I think the main hurdle, which I guess wouldn't be called a "complexity", of learning Spanish to a high level is understanding native speakers in natural conversation given how fast they talk.
TravelAndFood··on Changing emotions with a word: The subtleties of semiotics
"...they suspected that employing nouns (“I am in favour of the removal of settlers”), rather than verbs (“I am in favour of removing settlers”), to convey support for policy positions would have a calming effect."

This article is pretty frustrating. Another reason for this effect, and one I've always thought true, is that using nouns in English is often more circuitous, using more "fillers" like prepositions to convey the same idea, thus softening or obfuscating the harshness of the meaning communicated.

In other words, they don't seem to prove that nouns cause this effect, but that English's use of nouns causes this effect.

TravelAndFood··on Vipassana for Hackers [pdf]
Thanks. Just added "Godel, Escher, Bach" to my reading list.
TravelAndFood··on Vipassana for Hackers [pdf]
Cool quote from the beginning section "Computing Sidebar: LISP":

"The machine at the bottom of your consciousness is a strange loop. Having a look at this strange loop is a lot more fun than reading about it."

Awesome. Great style and expectation-setting in the intro portion. From my perspective as a programmer, occasional Vipassana-practicer, and not-speed-reader, and having read only the intro portions, this has piqued my interest enough to sink time into reading.
