htns··on The LaTeX cargo cult
>LaTeX will never be able to effectively render a LaTeX document to a web browser’s finite view of an infinitely tall document or read it aloud, because its output primitives are oriented around print media, and its apparently declarative constructs are defined in terms of them.

That is somewhat untrue. You can lay out content in a box of fixed width, and then set the page size to that plus margins. Now perhaps the performance isn't good enough for real time rendering, but setting up custom schemes is very possible and not as difficult as people might fear.

And LaTeX already supports PDF search, so I don't see why it could not support accessibility features like speaking the text.

htns··on The Misfortunes of a Trio of Mathematicians Using Computer Algebra Systems [pdf]
You could feed the proof to a (simple, verified) proof checker rather than check it by hand. Then you only need to check the statement that was proven was the one you wanted, without having to vet the code that spits out the proof line by line (until you actually hit a bug and the proof fails to check). I don't think it would be inconceivable for mathematica to implement something like that, though perhaps it's not really their core business.
htns··on A Natural A/B Test of Harassment
Yeah, I've heard about Gamergate in a couple of wildly different contexts. What's the deal with it?
htns··on Super-Intelligent Humans Are Coming
Wolves not barking is a myth, at least if I believe my first google hit.
htns··on Analyze Your HN Posts with Watson User Modeling
You can test the accuracy yourself: http://www.outofservice.com/bigfive/ . It's a good idea to take that test before looking at OP's results.
htns··on Become Estonia’s e-resident
pronounced ee'eesti
htns··on Eight Years of College Lets Finns Hide from Labor Market
That's actually a very weak part of the article. Finnish state unemployment benefits, even for the people refusing to seek employment, are bigger than students' grants. You are uneligible for unemployment benefits as long as you are eligible for students' grants. So while the grants may sound high to some, they are actually a scheme to discourage you from taking too much time studying.
htns··on Deconstructing Finnish
Finnish has various forms of consonant gradation, e.g. kyky (ability) -> kyvystä (from skill), or saapas (boot) -> saappain (by boots). I'm no linguist, but I'm pretty sure that hinders Finnish from turning very analytic. This is in contrast to say, Quechua, which is so regular I'm not sure how they decided which things are inflections and which are their own words.
htns··on Choose Firefox Now, Or Later You Won't Get A Choice
Sure it is hypocritical. Mozilla could just sell to someone else.
htns··on How to Be Polite
You will run into an awful lot of people thinking you are being sarcastic.
htns··on Why has Google cast me into oblivion?
Following the law is a joke? I may not like the law, but I rather like that Google does not get to be above it.
htns··on The Sinking Ship of E-Mail Security
I would suggest taking a look at I2P-Bote. Although I haven't had it installed for a year at least, I2P-bote seems to be a slow-moving project, with lots of features TBD, but it does hit all the keywords.
htns··on How to become a Good Theoretical Physicist
They are introductory in the sense that they are more about the horizontal bar of the T than about going in depth in a particular topic. But I guess I have to admit it was a poor choice of words.
htns··on How to become a Good Theoretical Physicist
On the topic of free introductory physics books, Landau's Course of Theoretical Physics (https://en.wikipedia.org/wiki/Course_of_Theoretical_Physics) is available on archive.org, since the earliest editions are out of copyright by now: https://archive.org/search.php?query=creator%3A%22L.D.+Landa...
htns··on So You’re Not Desirable
I agree with the second half of your post, but hunter-gatherer was an unfortunate choice of words. Societies tend to "evolve" due to scarcity induced by population density, as the first steps of the technology tree simply aren't that enticing when nature still provides plenty. Arguably we see the same thing with fossil fuels today.

What I'm saying is that I'm not so sure reaching a higher population is hindered by a liberal approach to sex (pre-contraception).

htns··on So You’re Not Desirable
And the trick is called "lowering standards". While attractive people surely have everything easier, I suspect the difference the study found is due to men seeking different things from "short" and long relationships.
htns··on FDA Dangles Golden Ticket to Spur Drugs for Neglected Diseases
This isn't the only fast track program the FDA has. While they might not be the most flexible organization, at least they are probably thinking in terms of risk/benefit to the public rather than in terms of safe/unsafe.
htns··on I'm About as Good as Dead: The End of Xah Lee
>ok living on a dime

Isn't that the perfect employee?

htns··on AdBlock Plus’s effect on Firefox’s memory usage
Does HTTPSB have a keyboard interface? I just installed it and it seems great, but I'd prefer to not use the mouse. E.g. NoScript has Ctrl+Shift+\ to temporarily whitelist the current page's domain and Ctrl+Shift+S to open the drop-down, and the drop-down works well with the arrow keys.
htns··on The Mystery of Go, the Ancient Game That Computers Still Can’t Win
I don't know Kurzweil's real position, but I believe in one of his books he expected singularity by 2045. A lot of people don't protest the idea itself, but the optimistic schedule.
htns··on Why bad scientific code beats code following "best practices"
Yeah. Most scientists are doing mathematics, not programming. Somehow math has done just fine without developing the patterns you see in programming. It's as if they weren't necessary in the domain.
htns··on It’s Easy to Hack Hospital Equipment
The risk is exactly that you can't tell it was hacked. Then the manufacturer might end up being liable.
htns··on The Linux Security Circus: On GUI isolation
Both fix it by making snooping and spoofing unavailable by default. An application only has access to its own windows, inasmuch processes are properly isolated in other aspects as well. Typically they aren't, e.g. very few distros have any "single user level" safeguards for ~/.bashrc. Qubes solves that problem as well.
htns··on A cash crunch at the Gnome Foundation
Doesn't teacup50 have a fair point? I would say that at least Mediawiki, Openstack, and some robotics foundation (all participating in OPW by taking interns) are well out of scope. All GNOME gains from being in charge of it all is a chance to make mistakes.
htns··on A cash crunch at the Gnome Foundation
They are hashing out the details on the email thread [1]. I don't know how correct it is but this post [2] in particular tries to give some numbers:

>You mention an estimate of $400k as annual turnover for the OPW, which (according to the most-recently available annual report that I can find, the 2012 one at https://www.gnome.org/foundation/reports/) is very close to the turnover of the Foundation as a whole ($418k income and $409k expenditure). Those 2012 numbers include $106k of Women's Outreach expenses, so the turnover of non-OPW Foundation tasks seemed to be somewhere in the region of $300k.

So apparently it caused turnover by being a huge source of growth.

htns··on Ask HN: Math books like SICP?
The Princeton Companion to Mathematics [1] is good if you want to gawk at the breadth and depth of the field. For actual education I would just suggest looking at a math department's syllabus, e.g. at http://ocw.mit.edu/. As a CS grad you should start with analysis, as that's probably your most looming dark spot.

My warning as a math student is that a lot of book recommendations are just a tad bit elitist. Don't stick with a single book too long if it isn't cutting it for self-study. Exercises are good.

htns··on World’s largest multirotor makes successful maiden flight
The article says

>The patented AT Transformer technology combines the capabilities of a helicopter, such as the ability to take off and land anywhere, with the capabilities of an off-road automobile.

I'm no expert, but it's clear the design was driven by very different requirements than a classic helicopter. Maybe there were many fancy considerations, or maybe they just slapped something together on the basis that bolting 3+ rotors to any old brick will give it flight and great maneuverability.

htns··on Drop Dropbox
Because voting by dollar is not democracy.
htns··on Drop Dropbox
To me, this looks like it may have been directly inspired by the Eich case. The whole premise is a little nonsensical. How will kicking her off the board change anything, when the shareholders (or whoever) who appointed her will remain? No time to answer questions like that when there is demagogy to do. It is a personal vendetta in a very similar vein as the Mozilla incident, even if the justifications may be better this time around.
htns··on A Story Of realloc (And Laziness)
I'm having a hard time picturing a situation where it would be tough to figure out. Typically you allocate memory to use it right after. errno will be set too.

Of course, there is no reason to not do all your allocation through a wrapper function which does check and abort on failure. I think the point was that surviving malloc failures is a dubious approach - instead go all in, or if it's a long-running service, provide a configurable max memory cap and assume that much will be available.
