How is it that inverse seems to be used as "multiplicative inverse" in this context? It seems like a really ambiguous term, because it could also be interpreted as either:

inverse of the square root (which is just the squaring operation), or

the inverse of some other binary operator, like addition or anything else...

MacOS High Sierra 9 years ago

Do you have any hints on how one might implement this on mac OS? I'd love to have my keyboard configured like this...

I don't know about other places, but on the highway in Michigan near construction sites they sometimes have signs saying something like "If you injure a worker, it's a $5000 fine and up to 25 years in jail".

Note the precedence of the $5000 fine before the 25 years of jail time. Clearly the Michigan DOT thinks that fines and jail time are necessary incentives to not kill or harm construction workers.

The call for larger sample sizes isn't always appropriate. It can often lead to spurious inferences.

As Jacob Cohen (famous statistician) has said, "all null hypotheses, at least in the two tailed forms, are false".

That is, with nearly any hypothesis about differences between groups, given a large enough sample size, you're likely to find a significant difference.

I'm finishing my PhD, and starting a post-doc in the fall. I had wanted to break out into industry, because I didn't see myself in academia in the long term, but I didn't get anywhere with job applications, so here I am.

I have a few questions:

1. My work consumes most of my time and energy - how would one find time to work on side projects and build a portfolio, when the academic workload is so all-consuming

2. I felt like I had to apply for industry jobs in my niche, otherwise I would be competing against a much larger pool of general engineers/science graduates. Considering that I've spent most of the last 5-6 years focusing on work in a specific niche, how can this be used for leverage for more general technical positions?

Thanks for the interesting article!

I don't understand that distinction.

In selecting a typeface, you're also necessarily selecting the font, so why make the distinction?

From an artistic and technical point of view I get it, but from a user perspective the two are not separable quantities.

I think research funding in general could take some cues from the Y Combinator funding model, in the sense that if you give smart people money and time, they'll discover/create amazing things.

You would think the value and return you get from investment in science would be apparent to anyone living in the modern age.

Is that supposed to be a trick question?

I can't tell if the answer is n(n-1)/2 or just n(n-1), because I'm unsure whether you would be looking to count a "bidirectional TCP connection" as 1 or 2 TCP connections...

Thanks for the explanation, closures have been a little tricky for me to wrap my head around.

I'm confused a little with regards to the closure closing over the "value" of free variables, or the reference.

For example, in python:

    i = 1
    def f():
        return i

    i = 2
    def g():
        return i
Both f() and g() return 2, even though when f() is defined, shouldn't i=1 be closed over in this case? That's what I find confusing here, in the sense that the state of the environment changes outside the closure affect things inside the closure.

Say I use my Macbook for development, and I compile a small toy C program using gcc. Does that mean now that I cannot run the produced binary by default?

Forgive me for being naive, but what does "app" mean in this context? Is a shell script an app? What about a python script with GUI elements?

I think this highlights inherent flaws in the governing body approach to web development standards.

I mean, if all the major browsers have it implemented already, why not remove the prefix? In fact, why have the prefix at all? If a feature X is unavailable on browser Y but implemented on browser Z, I can't see how the prefix Z makes any difference to browser Y.

In order for the MPAA/RIAA claim that copyright infringement causes large monetary damages to ring true, we must see profits increase in these industries.

If profits do not increase, then Megaupload did not impact profits.

Designing "Mute" 15 years ago

I'm not exactly sure how it did this, but my old Nokia 5800 used to sound alarms, even when the phone was turned off.

The device would power on somehow, alarm would go off, you would silence it, and the device would be off again.

I'm having a hard time following the scala.

Do you mind writing out what you're doing in pseudocode or in words? Intuitively, this result doesn't seem obvious to me.

Imagine where you have a one line scenario - you watch which register people go to. Label people who went to registers A,B,C with A, B and C respectively. Then, repeat the situation, but instead of one line, use 3, where everyone labeled A stands in one line, B in the other, and C in the third.

The transactions play out exactly like before. I realize we're dealing with probabilities and expected values, but it's definitely not obvious to me.
