You can wax poetic all you want about anecdotal values differences between the first and third worlds, but speaking in terms of actual practical impact: what you are saying is simply not true. Greenhouse gas emissions scale super-linearly with income: https://www.iea.org/commentaries/the-world-s-top-1-of-emitte...

There are dozens and dozens of studies all reaching this same conclusion, if the International Energy Agency isn't good enough for you: https://www.google.com/search?q=greenhouse+gas+emissions+by+...

OP's point was that the global rich (most US citizens included) have lifestyles and patterns of consumption which produce an outsized amount of greenhouse gasses, and any attempts to alter those behaviors are routinely met with anger and political backlash

the reason they are named differently and are notated differently is that they serve different functions. they're more or less homophones.

or, perhaps to keep it within the artistic sphere, they're like https://en.wikipedia.org/wiki/Checker_shadow_illusion and other "same color" illusions -- they are technically the same, but taken in context they signify different things.

you would build different chords around them, you would play different melodies around them, etc. in other words, it's not just when writing them out in english that we treat those two intervals differently -- we treat them differently while using them during music

you are, of course, correct that many very competent musicians would not correctly name this distinction using the official theory terms. but that doesn't mean that they don't understand the distinction when using them in musical contexts, or that the distinction is not meaningful. plenty of professionals are experts at something without being able to describe it perfectly in words

This seems to be exactly the definition given in the article?

a documentary presenting an impersonator as the real person has always been unethical, yes. this one is newsworthy because it was done in a new way.

I figured that, but I wanted to give the chance at clarification, because we were mainly discussing operational expenses, and there's no way data centers even clears 1% of the cost of running Harvard

Of course! The point was to put the number next to a number known by the typical HN reader, not to imply the businesses were at all similar.

> Most universities get by with a dozen clustered on campus serving administrative, educational and research objectives

... A dozen what?

Invests it, and runs the university on the returns. Assuming a 4% yearly rate of return, then that's around $1.5B a year in money available for operating expenses. As a point of comparison, Facebook spends ~10x that (~$15B), Uber spends ~2x that ($3B), etc. Harvard obviously has additional revenue streams, but there you go.

When I'm in my working tab group, that's like 8 tabs or so. Most of the tabs in the storage groups are months old (more like bookmarks I didn't have to hit Cmd+D to save)

Ctrl+tab'd thru all 56 tabs in this group, waited for them to finish loading, opened activity monitor: CPU at 20%, RAM at 811MB. So yea, a fair amount weren't loaded, but loading them didn't make too big of a difference.

Firefox with Tab Groups and AwesomeBar fits very nicely with my workflow--

1. I dont have to think. I Cmd+Click links as I find them interesting, switch tabs as my attention changes, etc. and the tabs just stay there, waiting.

2. AwesomeBar searches over open tabs by default, and selecting a suggestion switches to that open tab rather than opening a new one.

3. When I have time, I can sort my tabs into labelled groups ("Work", "Research", "Shopping", "Politics", etc.)

4. Tabs are sync'd to and from my Firefox for Android automatically, so if I'm on the move and I want to pull up that thing on the tip of my tongue, it's right there on my phone as well.

I'm sure it's not perfect for everyone, but it works for me /shrug

Mmmm that's true, I don't. I tend to close GMail tabs once I'm done with them because I also noticed they tend to leak and are poorly optimized for non-Chrome browsers.

Mac El Capitan, FirefoxDeveloperEdition (which iirc is basically equivalent to Firefox Beta), not many addons (Tab Groups, uBlock Origin, No More 404s). I can screenshot my Activity Monitor if that'd help?
