What the article is referring to is that de Sitter spacetime, which is an idealized universe that only contains vacuum energy, has no initial singularity; it extends infinitely far back in time (and infinitely far forward as well). This is the basic model (at the classical level--see below) used to describe inflation, so in that sense I think the answer is that the "no singularity" result applies to all inflation theories.

That's not quite the end of the story, because the idealized model I just referred to is a classical model; it doesn't include quantum effects. I think the general opinion among physicists is that, if we extrapolate inflation back far enough, we reach a point where quantum effects become important, and the classical model above no longer applies. I don't think anyone expects a quantum model with an initial singularity to replace the classical model in this regime; but at this point we don't know what the correct quantum model is.
Let's extol the virtues of fear and hate, while we're at it.

Yes, it's normal to get anxious sometime, just as it's normal to get angry sometimes. Someone who never, ever gets angry could be suspected of bottling up their feelings (but we can't be sure). Our emotions aren't under direct voluntary control, so if we find ourselves getting angry, or anxious, or fearful, we must aim not to freak out, or criticize ourselves for it, or become anxious about our anger, angry about our anxiety, fearful of our fear, or any other such downward spiral. Emotions are normal; they are ok.

However, doing what a negative emotion says to do usually doesn't work out as well as doing something else, in my experience. While we can certainly find evolutionary justifications for the things we feel compelled to do under the influence of these emotions, that doesn't mean they are helpful. Fear tells us to flee, to avoid, to destroy, or to deny. I've read that highly successful people who seem fearless do feel fear but just aren't as bothered by it. I think this says the exact opposite of the OP's message, which in this analogy would be The Importance of Fear: It Tells Us When to Run Away. The hard part about fear is acknowledging it and not running away. That is called courage.

Similarly, anger. When you are fighting with your wife (or co-founder), they may say something that you take personally and it hurts your feelings. You are outraged. You strike back, and a fight breaks out. Ok, that's fine, that's normal. But one of you, at some point, has to ignore the anger voice that tells you to defend yourself at all costs, and to attack your enemy's weaknesses. Yes, your partner has become your enemy, thanks to anger.

Anxious drivers don't drive better than non-anxious drivers. I may have moments of anxiety when I drive, such as if I notice a car about to merge into me and I swerve. Perhaps the anxiety plays a physiological role in helping me respond. However, it takes many seconds for the feeling to subside, during which time the anxiety is not helping me, it is hurting me. It also seems naive to identify the feeling of anxiety with the biochemistry of responding to an urgent situation. We could just as well say anxiety is a psychological state which is a harmful byproduct of the physiology.
Damn. What's wrong with Hacker News today? Everyone is being amazing!
How does that even square? According to your initial premise, your problems are not deaf people's problems (except insofar as they choose to act on empathy they may feel), and they should do everything in their power to maximize their access, even if it costs you. If you want to live in the state of nature, everyone has the right to trample on everyone else. Mercifully, our social structure still is more in line with Rawls than Rand.
Small super-pedantic note: the correct file 'so that it is set every time you log in' on both OS X and Linux would be .bash_profile.

- .bashrc is run every time the shell is started (eg, subshells, su without -l or -)

- .bash_profile is run only when a 'log in' shell is started, eg, a tty, su -l, su-, new tab, etc.

The article describes how anxiety helped an individual navigate through a social situation... but who's to say allowing anxiety to control your behavior is better then having calm rational judgement dictate your actions?

In the past where people would declare formal duels in response to some verbal insult, anxiety was a relevant response to save your life. But in this day and age where people have much more to gain and very little to lose when being assertive and fearless in social situations, anxiety has become an excessive and prehistoric response that is largely irrelevant to the times and culture we live in.

Here's an example relevant to most men. Why aren't we talking to that hot super model at the bar? What do we have to lose? Nothing. What do we have to gain? Everything. The logic is inescapable but why are we still scared? Because in the past hitting on a super hot model meant dealing with her alpha male partner who could kill you in a duel. The emotions we feel are evolutionary relics from prehistoric times that were designed to keep us safe. These emotions are now largely irrelevant because murder and combat in our society is both frowned upon and considered a crime.
Have we seen malware ripping keys out of memory? It seems a stretch to think that making this slightly easier to do will result in it being more widespread. What reason does malware have to do this that isn't better served by DNS Hijacking + installing a root cert?

This is incorrect. Costco warehouses only accept American Express credit cards. Visa and MasterCard debit cards are fine.

This may be true about Go, but Rust's traits were very similar to Haskell type classes and now are equivalent in power to Haskell's type classes with several extensions turned on (even though they lack HKTs).

As a side note although clunky HKTs are encodable in Rust and I plan on implementing them natively once we have landed a stable version of 1.0.

Ask HN: How does code completion (as in IDEs) work on a technical level?
Conceptually, I understand the parts, but I'm having trouble translating that to working code. I've been doing some research and came across Jedi (https://github.com/davidhalter/jedi), which is an autocomplete library for Python.

Is there some guide somewhere that walks through the process of building something like Jedi for some other language (even an imaginary one)?

While it's tangential to this particular discussion, my goal (eventually) is to learn what I need to know to be able to build something like Jedi for PHP. There's only a handful of options for PHP code completion, and none of them provide the level of intelligence of a proprietary IDE like PhpStorm. That needs to change, IMO.
> if I got divorced my wife would automatically get custody because I would not legally be able to take custody, not being a person.

This isn't true. You're still considered a person but you're not considered a citizen. Big difference. Koseki does not (nor should it) grant you the same rights as a naturalized citizen of Japan. Becoming a naturalized citizen (through citizinship) is a step which you (or anyone else who qualifies) can take if you want, but it takes a bit of time (same length as becoming a citizen in the U.S, ~10 years).

In your comment, you don't differentiate being a naturalized citizen of Japan and a koseki. But there's a huge difference. A koseki is something different and apart from becoming a naturalized citizen. It shouldn't grant you the same rights if you're a foreigner, it wasn't meant too.
Everybody chill out, it's just a lawsuit. Four Americans disagree with how Harvard and M.I.T. are interpreting the 1990 Americans with Disabilities Act, and so they're asking the courts to help out with the disagreement. I doubt anybody here will disagree with Americans being able to use their courts to redress perceived injustices.

As to the ultimate outcome, I'm calling it: Either DOJ will clarify the rules so that captions are required, or the schools will settle the lawsuit by agreeing that captions are required, or the courts will decide that captions are required.

And then 30 years from now, at least one person in this thread will have lost their hearing but will click open and watch a captioned M.I.T. or Harvard video without even thinking about how much they railed against that one article on HN back in 2015.

Maybe instead of the "good luck" attitude we should start pushing an "upgrade or suffer" attitude.

Seems far more reasonable than letting things stagnate for years. It's what chrome is doing with sha1 certs.

Give a timeframe, if you don't get your upgrade in then too bad.

> Even more intriguingly, SigOpt helps you optimize physical experiments. For example, Clark said one of his initial customers is using SigOpt to test different chemical combinations in creating shaving creams. It shouldn’t matter what you’re testing — Clark said SigOpt’s technology just uses your data and “builds up this model of what it thinks the world looks like. … It’s designed to be a very general system.”

This is really vague, can you give some more technical details on what's actually happening?

And if you read the PR release carefully, no where does it specifically say one of those courses isn't properly captioned. The examples it gives of non- or poorly captioned items aren't even courses at all (http://nad.org/news/2015/2/nad-sues-harvard-and-mit-discrimi... which is a really nasty piece of work).

Without looking at the lawsuit (waiting for lawyers like the Instapundit to tear into it, he's big on non-traditional learning like this), I suspect the mention of MOOCs is bullshit, confounding perhaps a MIT Open CourseWare (OCW) offering with the edX ones you're talking about, which others in this discussion have ensured us are properly treated.
That half a page of code isn't "Lisp in itself".

I do not see any low-level I/O routines, or a reader to scan expressions and convert them into objects.

I don't see the actual function call mechanism: where the subroutine linkage is set up and torn down, and what goes into what register.

I don't see a garbage collector.

A whole bunch of hand-written assembly language made the code on that page work.
Could you elaborate on what you mean by weirdly dystopian? I don't feel like I got the same vibe.

It's not very expensive to do escape analysis well.

Escape analysis is essentially a sub-problem of points-to analysis, with less resolution on the answers (The document actually points to why)

At worst, it is as expensive as points-to analysis, which, good ones, while N^3 in theory, are not in practice.
(they scale to millions of lines of code per second).

The points-to analysis I implemented for GCC, which is field sensitive, is N^3, but is run on every compile, and basically never shows up at the top of profiles. It is used to compute escape analysis results as well. It's not even state of the art anymore.

Alan Donovan wrote a go points-to analyzer for other reasons using the same algorithm but a better solver.

I'm not sure where you would ever get N^6, that sounds just truly horrible, and doesn't match any time bounds i'm aware of.

(flow-sensitive points-to is not even N^6, and context sensitive points-to are all 2^n theoretical worst case, even if they are not anywhere near that in practice anymore)

As for what to do, it's not a dichotomy.
They should do both :)

People whose expertise is GC/runtime are often not the same as whose expertise is in the algorithm/analysis side.
I don't think that's accurate. Certainly some people work jobs just to get cash to pay bills. But plenty of people create for the fun of it.

Our brains operate suboptimal because we can not control their state. We get worried when it provides no benefit. We get sad and troubled when we shouldn't. We experience intense pain with no way to shut it off. We lose focus, even when we really want to concentrate.

Everyone should have the capability and choice of modifying their brain chemistry on demand. Your premise that people should be forced to be unnecessarily unsatisfied because some of them might go on to do great things is cruel.
Expedia to buy orbitz
I know several of the lawyers involved on the plaintiff's end (several of them blind and/or deaf) on a friendship, nonprofessional level -- and I'm noticing there's a lot of misunderstanding in the comments. However I am not a lawyer nor am I hugely aware of the nuances of the issues, so take this with a grain of salt.

Basically the law firm in question is using lawsuits as a method of social activism to compel large orgs to adhere to the ADA. (Similar thing happened to Scribd.) Basically deaf/blind nonprofits ask these entities in question for open accessibility accommodations and typically do NOT get denied the request, but this ends up being a low-priority task that gets tabled for years. Unfortunately between asking nicely, mobilizing social support to effect change, and lawsuits, the legal stick is by-and-large most effective at making things happen.

This is also NOT a shakedown; the end goal is NOT that lawyers or plaintiffs get fat stacks of cash, but that these accommodations be implemented. To the disabilities orgs, these requests are similar to asking for accessibility ramps and what not.

I'm just trying to let FB know of a potential phishing attempt that's targeting all Windows users. I don't care about the bounty, in fact I only care a: to teach MS a lesson and b: to annoy the "developers" scamming people. I don't care enough to sign up for FB. Every other company I've dealt with on this, except some of the large media companies, have been easy enough to contact about the problem.

To be clear, the issue is: Windows users using the Windows search feature, or directly using the Windows Store, are presented with fake FB apps claiming to be official. Contacting MS support gets useless replies, as they are trying to pump their app counts. Meanwhile, normal users end up installing a potentially malicious app, claiming to be the official FB app. FB needs to send a takedown.

> For the purposes of armchair moralizing, who cares about the law as written?

Because the law embodies certain moral conclusions. The ADA is premised on the idea that businesses have an obligation to make reasonable accommodations for the disabled. At least in 1990, this moral conclusion was compelling enough that the ADA carried a 377-28 margin in the House, and a 91-6 margin in the Senate.

As an aside, to me, laws like the ADA are one of the things that make America great. It is a virtuous people that decides that the lucky among them should take on the burden of enabling the unlucky among them to live life as normally as their disabilities allow.

It's the ability of DNNs to replace feature engineering that makes them interesting. They have completely obsoleted feature engineering in object recognition in just a few short years.

Deconstructing Joyent's CTO New Docker/Linux/SmartOS
Read this mendacious, invidious PR thuggery http://nad.org/news/2015/2/nad-sues-harvard-and-mit-discrimi... and tell me again it's "just a lawsuit".

And as has been amply pointed out, in the case of any of the outcomes you're calling, a great deal of material will be withdrawn from the net (or campus servers and official Youtube channels), little will be returned, at least from MIT, which doesn't have the money (well, absent a big fundraising campaign, which would crowd out other things), and perhaps most importantly, it will have a serious chilling effect on future offerings, since they will have to be vetted for not just captioning, but sufficient quality captioning, "by legal". MIT students, at least, have better things to do with their time.

And 3 years from now, let along 30, at least one person will click on a "see the video" link and get a 404.

And you severely underestimate people's memories, and ability to hold grudges.

Didn't anyone else find this post suspicious ?

I browsed through the site thinking there were some other interesting security posts.

Turns out this is the only post on the site. Then I did a Whois and this site was created 2 days ago. It's registered to laksshmanan51@gmail.com which is apparently the same guy on the post. Then I did a search on Google for laksshmanan51@gmail.com and there are search results with "You can earn huge using your Facebook page. Please let me know if you are interested. Shoot me a mail laksshmanan51@gmail.com"

This just doesn't pass the smell test with me, seems to me this guy just pwned a lot of people to get ad clicks or something else.
New Relic’s First Post-IPO Quarter Beats Expectations
Great question. We build off of research in Design of Experiments [1] in general and Optimal Learning [2] in particular. Our algorithms attempt to make the tradeoff between exploration (learning more about the space we are optimizing in) and exploitation (using the information we have to achieve the best values) to find optimal parameter configurations for experiments as quickly and efficiently as possible.

This has been an active field in academia for the last few decades, and the seminal paper behind some of our algorithms was published in 1998 [3]. There have been many successful applications in different fields from drug discovery [4] to nanotechnology experiments [5].

We wrap these powerful techniques behind an API and web interface to let anyone start running optimal experiments and leverage this research right away for any experiment they are trying to optimize. We have some more examples and a use case on our site [6].

Does anyone know why there's such a huge disparity in these different types? I'd think the revenue would start getting driven down toward the value added, and I can't imagine the value added by a website varies so much between plane tickets, car rentals, and hotel booking.
Inaccurately, programming language = syntax + semantics.

Do not waste your time on syntax, if you are going to create a new language, rather than a parser.

I'm not saying that syntax is not important. But I feel semantics deserves much more attention.
