jckt··on Make Dinner: A Home Cooking Manifesto
Happy to see a cooking thing instead of a Soylent thing on HN (but to each their own). An article in similar spirit, but more focused on why you should consider cooking at home, rather than how you would go about doing so:

jckt··on An Infamous Art Forger on His Most Convincing Works
I don't think your description of copying is particularly useful regarding physical art, as that type of "replicator" technology (molecule switching) is far, far away. In reality copies are, well, never so completely identical (far from it). Of course whether or not one can actually detect the differences is another matter, and at which level of detection one is required to differentiate copy from original is necessary is yet another.

What do you think about museums -- a public institution that is more or less the antithesis of your view of the art world? Without going into semantics, let's say you have a genuinely old artefact. Now someone comes along and makes a replica. Let's say they're virtually identical, and the only difference is in the carbon dating, which you can't really fake. Which one should be admitted into the museum?

jckt··on Low-Salt Diets May Pose Health Risks, Study Finds
"But looking back significantly further than that", says the GP. Our bodies are mostly what they are based on thousands of years ago (or more), not hundreds. In other words, the 1900s are irrelevant.

It cost a lot of time/energy to hunt, for sure. But that's basically all they did. And reading descriptions of say, the Americas before European colonisation, meat was plenty despite industrial breeding, or any breeding at all.

Interesting to note that ctrl+shift+f, which on the desktop version is a shortcut to jump to the search area context, works in the mobile version but doesn't let you type (for some reason).

I think it only saves energy on CRT screens, which is not popular these days.

jckt··on Cockroaches live in a democracy (2006)
Maybe intelligence isn't the right word? As I understood m52go's comment, it's more like smaller brains -> less variations of "mind state" (as in state machines)? Hence less "variance of intelligence".

Of course, I have no idea how a brain works, and it's unlikely that it's anything like a computer.

jckt··on Digital identity cards: Estonia takes the plunge
Isn't that because the US is so big (and also with a huge economy I guess)? Most countries are much smaller (like Estonia, or its neighbouring countries) and leaving the country isn't as big a deal.
jckt··on Teaching college is no longer a middle-class job, and everyone should care
I think another problem (though probably minor compared to the bloated bureaucracies everyone else is mentioning) is that the teaching quality doesn't matter as much to students these days.

This is a UK source, but I think it reflects the view of most students in the West:

http://www.bbc.co.uk/news/education-14616788

I feel bad for saying something like "kids these days" (I'm one of them, admittedly) but "fun" seems to be a big factor in a student's choice of a school today. Admittedly, this is mostly based on anecdote and stereotypes (I think there's a reason why "college life" is commonly associated with parties and frats). I won't say that the social aspect of education is unimportant, but it seems that rather than making the education itself more "fun", universities in the last few decades have gradually increased funding for recreational buildings, big events, frats, and sports [1], etc. Of course, I don't know how significant these costs actually are, and I'm happy to be convinced by some budgetary data if this is actually a non-issue.

jckt··on What Happened When We Tried to Publish a Real Paper Investigating Time Travel
I feel bad derailing this thread further, but you know bloody nothing about me.

My comment was on-topic. grkvlt's was not, regardless of what he thinks I meant with that one pronoun (which was wrong, anyway).

Maybe you should realise that sane women, just as much as sane men, don't think pronouns will "solve" sexism. If I'm referring to a specific person, I'll be specific. If it's some random imaginary person, it's none of your bloody business what pronoun I choose.

jckt··on What Happened When We Tried to Publish a Real Paper Investigating Time Travel
You're easily irritated, no?

Maybe I'm a girl and, try as I might to say "he" all the time (to avoid comments like yours), the one time it slips and I say "she" the Internet thinks it's all about some "femi-nazi" agenda of mine?

Chill out and talk to me about sexism/feminism/SJW when it's actually relevant (clue: not here).

jckt··on What Happened When We Tried to Publish a Real Paper Investigating Time Travel
Can't edit, so correction: "...no reason why such a journal should not exist..."
jckt··on What Happened When We Tried to Publish a Real Paper Investigating Time Travel
Yeah, that's why I said that my comment was slightly off topic. It was more concerned with the tech crowd (like HN I guess) treating the possibility of FTL/time travel with such seriousness, which is somewhat out of character for a crowd that is normally pretty well-educated about science.
jckt··on What Happened When We Tried to Publish a Real Paper Investigating Time Travel
I can't seem to find the claim in the post where the journal editors actually said "this can't be publishable, period".

I am pretty sure that when the physics journal editor rejects your paper, she isn't even actually saying "this can't be published in a physics journal", she's really saying "this can't be published in this physics journal" (unless she says otherwise, explicitly, of course).

jckt··on What Happened When We Tried to Publish a Real Paper Investigating Time Travel
Can you elaborate on "beneficial"? Beneficial for what? Sure, perhaps the time travel paper captured the public imagination. But so does movies and novels.

Though I didn't see him talk about it at length in the blog, I can see that he might have meant that such a journal would be good for interesting future generations in science. But is this really a good idea? They would come into physics, or whatever, with the expectation that such research actually constituted hard science. It is not.

Interesting future generations about science is hugely important, but this is just a dishonest way of doing so.

And also, this may sound a bit harsh, and I might be out of line here, but I think the point of the paper was really to get some attention. And personally I think there's a trend of this happening in physics' interface with the public -- scientists wanting attention for themselves, apparently for the sake of future interest in the field. There seem to be a lot of popular science books these days, many written by genuinely brilliant scientists, who seem to be trying to sell their own theories as truth, like the various string theories and other GUTs. While I am sure that the authors don't really mean to say that their theories have passed the sniff test of science, and that we can put their theories on the same shelf as GR and QM, my observations from friends and people on the internet tell me that a lot of them just gobble it up as truth.

PS: Not saying that the GUT formulations are in anyway comparable to Nemiroff paper.

jckt··on What Happened When We Tried to Publish a Real Paper Investigating Time Travel
Slightly off-topic, but normally HN is scientifically sound when physics or any other science is mentioned. But when it comes to time-travel/FTL, I can't help but feel that half the posters here seem to almost want it to be true. Or at least seem to think that all of our physics knowledge is worthless when it comes to FTL et al. Or is everyone just having a laugh?
jckt··on What Happened When We Tried to Publish a Real Paper Investigating Time Travel
By "different views of time" do you mean a scientific view, or a philosophical view? If it's the scientific view, the idea regarding time and macroscopic bodies -- general relativity -- specifically what you'd need to describe someone travelling in time, explicitly forbids that, so I don't think there is actually any possible scientific answer to your question.

Philosophically, but something vaguely based on physics, there's the Many Worlds Interpretation of quantum mechanics. But as far as I know the "physical meaning" has no bearing on science. There's a good sci-fi novel about a universe where the MWI is true -- Anathem by Neal Stephenson.

jckt··on What Happened When We Tried to Publish a Real Paper Investigating Time Travel
I agree. His attempts to get his type of paper being published in established physics journals are sort of explained in his last paragraph though. He thinks that there's "room in the world of publishing for science motivated primarily BY public interest, instead of IN THE public interest". Certainly there's no reason why such a journal to exist--free speech and all.

I'm not a physicist, but certainly saying that such a journal does physics is a bit of a stretch? Ignoring the fact that he hopes such a journal could accept hard sci-fi (of which I am a fan), how could such a journal be maintained properly if it was driven "BY public interest, instead of IN THE public interest"? The general public is ignorant about science, especially deep science -- which is absolutely fine. Funding agencies (as I understand them) are here to help us decide what to do so that not all of us have to go through graduate school to get an idea about the state of science. Moreover, it sounds to me that he wants a more "democratic" process of science. Democracy makes sense in politics -- we vote on politicians because they have the power to change our lives. But scientists, especially physicists, are powerless to change Mother Nature. Regardless of who we choose, as long as the physics is done half-decently, we're going to get to more or less identical answers.

jckt··on What are the advantages of the Hurd over Linux/BSD? (2013)
According to this paper[1] about L4, it seems to be the former (that is, performance has genuinely improved).

jckt··on I'm About as Good as Dead: The End of Xah Lee
Same for me. I came across his site (through some usenet emacs stuff) and read his blog entries...I'm all for free speech and all, but I don't think a lot of his opinions would be considered, especially on HN, "unacceptable". Some of it might even be considered "creepy"[0].

It also doesn't help that he is insistent on using his own brand of English[1].

I don't mean to say that you shouldn't help him out. And I definitely can't say if he "deserves to be homeless/near-homeless". Just want to point out that the reason why he hasn't been hired isn't mainly because he has had "no corporation to witness to [his] ability", as someone else pointed out.

Edit: Just realised his writing style is only used on his blog, and not in professional stuff.

jckt··on Ask HN: How did you find Hacker News?
A random Google search. Thought, with a name like "hacker news", I'd come up with a lame "script kiddie" site full of teenagers or something. Couldn't have been proven more wrong.
jckt··on Show HN: OpenRA – RTS project that recreates Command and Conquer games
Glest/MegaGlest[0] is also another FOSS RTS project. When I last played it it felt a bit like Warcraft 3, but definitely not a clone (no heroes as far as I remember).

Certainly you can't expect every article to be written for a tech-literate audience?
jckt··on What I Learned Negotiating With Steve Jobs
I guess I meant normal as in not-a-sociopath. As another commenter said, Gates was definitely intense. But then a lot of other people can be similarly described (maybe not to the same degree, but someone like Linus is not exactly known for being mild mannered[1], but he's definitely not a sociopath).

But thanks for the link though, I'll check it out. I must've suppressed all my Gates-criticism for all the good he's doing now.

> filtering out everyone who wasn't a born narcissistic enabler.

Do you mean that there instances where he really listened or liked/respected/etc someone because they had similar narcissistic tendencies? I was under the impression that people like him tend to hate people like themselves -- a narcissist who thinks he's the best is at greatest odds with another narcissist who thinks he's the best.

jckt··on What I Learned Negotiating With Steve Jobs
I think Bill Gates is a good counterexample. Microsoft was not the nicest company around, but as a boss he seems pretty normal, even good. And I'd say he's just as successful as Jobs, if not more. (Also difficult to imagine a sociopath being a philanthropist like Gates).

It's not so much that it's military equipment. Some of it is just amazing engineering, regardless of context. Since many HNers are engineers, it is not surprising that posts about interesting/amazing feats of engineering get voted up.
