I was replying to wting, but HN doesn't let me reply to a reply by the same author as a way to combat back-and-forth style arguments, I guess. He said that experts doing that is "trained pattern matching gained through experience, i.e. mach

I see it more as a Family Feud style of reasoning. It's not just "how to ask the question" but "how other people would ask the question." Being able to model how other people would ask the question (empathy) is a key skill. In my mind usi

It's funny because that's perfectly backwards. :) Machine learning is a model of this thing we observe in ourselves. Don't mistake a picture of a pipe for the pipe itself. http://en.wikipedia.org/wiki/The_Treachery_of_Images http://en.w

I have no idea, unfortunately. One of our fundamental theses is that much of what we teach is difficult-to-impossible to teach outside direct human-human interaction. So, try to solve that first, c.f., http://www.quora.com/What-is-the-mos

This is something only someone who was already on their way to being an expert would say. :) A beginner with a broken, incomplete, or confused model of the world won't be able to accurately assess whether a new piece of information is consi

It's more broad than that. I'm pretty sure that's just what it means to be an expert at anything. You have a set of heuristics at work as an expert. To a beginner, everything has the same emphasis. They won't even be able to differentia

Yes! It's developing the judgement that separates an expert from a non-expert. Effective use of Google is a consequence of that judgement, not a cause. More formally, it's nothing more complicated than a standard fallacy of the converse.

As I read the article, I don't think that's what Fowler was talking about. I think he noticed a trend in things like Less, Sass, Haml, CoffeeScript, etc. The relationship between, say, Haml and HTML is qualitatively different than the rel

I started programming in high school as a hobby and went on to study mathematics and linguistics at the University of Chicago, where I graduated in 2006. The date is just to give a sense of the timeline: it wasn't until 2-3 years ago that

Unique inside Mega, yes, but not globally. Imagine if UNIX systems did as you propose. The rainbow table for the salt "root" would let me do plenty of damage.

The higher the entropy of the salt the better. Let's say everyone did as you propose and use usernames for salts. I could pre-compute dictionaries for usernames like root, admin, etc. and likely gain full access to a wide range of systems.

I think you're confusing encryption and KDFs. Encryption is meant to be reversible, KDFs are not. In this context, a KDF is used for verifying that a message is valid. I have a derived key, you give me a key, and I verify that key by runn

Without a salt one can pre-compute all the KDF (input, output) pairs and store them in a dictionary (essentially). This single dictionary now acts as a kind of master key. By including a random per-user salt, even assuming the attacker has

TapJoy hired 6 or 7 of or summer students out of 30 students interviewing. They were the largest single employer, but definitely not the majority. :)

The sounds effects are cute, but bleed into each other and produce strange noises if you type faster than your average bear. And bears don't type that fast, as you know. iA Writer is a similar desktop app that I use for most of my writing:
