Also, AMS LaTeX, by its nature, allows you to write custom macros to shorten the particular notation(s) you happen to use most. A lot of these comparisons fail to note that important fact about the use of the tool.

Obviously as I am a well-above average programmer, any of these metrics that do not clearly document this obvious fact about me are either old-fashioned academic fashion that have nothing to do with the way real programmers write code or po

It's probably of value to note that that diagrams that everyone is talking about are not part of the original text.

It's generally understood that the theorem, and in particular the 1/1/2 and 3/4/5 integral triangles were known prehistorically and independently 'discovered' in several places. It's not possible to k

Except that group selection isn't a non-controversial idea in evolutionary biology, and shouldn't be causally invoked unless you're prepared to get into multi-level selection theory, kin-selection and haplodiploidy, replicato

If you took three semesters of post-secondary maths and never encountered "∈", you should ask for your money back.

"Survival of the Fittest" was not Darwin's idea. The phrase was coined by Spencer, who misinterpreted Darwin's work. It has since been used primarily to either further misunderstanding or to apply Darwinism to realms lik

No the message is "that was never the Darwinian view, why don't you actually read his work?"

About every 18 months someone in the popular press feels the need to point out "exciting new research" that shows that nature isn't really red in tooth and claw, but that evolutionary biology even seems to show that cooperati

In Lamport's defence: (1) He's Leslie Lamport, so his comments about academic Computer Science should be at least considered before they are dismissed. (2) His audience (and the target of his critique) was not an arbitrary set of

His response would be that anyone who's studied even a little college math wouldn't need that legend. I learned that notation in High School.

Crew-rated is radically different from passenger-rated in basic safety requirements. The problem with quad copters is that they're unstable in flight after the loss of only one engine, and lack sufficient mass in the propellors to effe

I forgot to add a quote from an engineer I used to work with: "Safe enough for a test pilot is very different from safe enough for the test pilot's kids."

True, but the fuel to get up to that altitude is a significant cost that can't be ignored, and the mass must be carried at takeoff (unless you want to solve the problem the way the USAF does, but I don't even want to think about p

People always seem to grossly underestimate the cost to crew-rate, and then passenger-rate vehicles. Especially with new technology, which usually involves killing people along the way. It is much, much, more expensive to develop a system

In my experience, most people who use emacs as a primary tool run it in server mode. On modern hardware, its footprint is trivial, and that allows you to launch the interface in a fraction of a second. My machines all have an alias for emac

Yep. My Math is undergraduate Electrical Engineering and Graduate Comp Sci. Some of the stuff I'd have to bone up on because I haven't done it in a few decades, but all the problems were familiar and seemed tractable---seemed ap

Hah! I gave 3.1 - 3.4 as an assignment to second-year CompSci students literally three weeks ago. Although my version was to determine the values experimentally for n<=8 bits and then estimate values for n up to 64. Bonus marks awarded

While Orthodox Judaism (and be careful, there are distinct flavours of what 'Orthodox' means and multiple authorities) holds the Torah to be the revealed truth of God, the concept of an "obvious, literal interpretation"

The canonical discussions of just this issue through Torah, Midrash and Talmud, as well as later Rabbinic writings span literally volumes. It is not possible to be "exact" about the halakhah around portrayals of G-d, which includ

It's still standard for dead languages (cf. Wheelock's Latin, any Biblical Hebrew text, Koine Greek, Classical Greek, Aramaic, etc.). Modern languages have tended to shift into a focus on conversational use rather than scholarly

Yes. I particularly remember Asimov's death as it came only a few years after Heinlein's. It was a reminder that we were losing the last of that first generation of greats. I got drunk and cried on my father's copy of &quo

"Proven Technology" != "Many are currently in commercial use". Had I meant the latter, that's what I would have said. The initial theory behind MSRs was well-defined prior to the 1960s, and experimental reactors (

Sigh. Claims made by a few people about a particular molten salt reactor design do not stand up to scrutiny. Molten salt reactors, on the other hand, are proven technology.

I don't have a problem with saying we really need to address pollution from bunker fuel. I have a problem with purposefully selecting misleading data to bolster your argument.

But, in this particular domain (non-carbon oxides) ships AREN'T like cars---that's the whole thesis of the story.

by ajarmst 10y ago
Because they speciously choose to compare ship emissions to cars, which emit almost no oxides in the limited classes they select (because almost all their emissions are in the excluded category). This is an bald attempt to make the problem

The lede is false and misleading on its face. Excluding "carbon dioxide" from your list of "oxides" when discussing (and comparing with) automobile greenhouse gas emissions is absurd. The misleading claim is also clearl

Reserving judgement until I see an analysis from someone familiar with the pertinent law, and qualified to comment (i.e. "What does Eben Moglen think?"). The "analysis" linked to is a dead link (maybe it got HNed).
