But do you think the strategy of cutting fares could actually work? I wouldn't think so. It appears that investors are willing to fund the second largest player now, and I see no reason that wouldn't continue for at least as long as Uber's investors are willing to throw money at them to subsidize fares.

Then pretty much by definition we wouldn't hear about it, would we?
I don't own one, but one possibility that springs to mind is, if you wanted, you could pack your garage with crap, leaving only a car-spaced hole. (You know, like most people do, except for the hole.) Then you use this feature to extract the car from the garage, without needing space to walk to it or open doors.

I'm only partially joking. Our two-car garage is basically large enough for two average size cars and.. that's about it. We prioritize parking over junk-collection, but I could see the use. Of course in the winter, in some climates at least, it removes one of the main benefits of the garage.

I guess one other benefit would be that you could always use your front door, whether walking or driving, so your shoes and stuff could all be in one place. Might be a minor advantage for some.
People are also good as self deluding themselves with statistics.

London has an even older system, with more constraints (it was built with two tracks, not for). Yet they are doing the right scale of investment: new lines costing billions.
I think those buyable-button-like initiatives are inherently flawed from ground up.

Clicking ads, comparing to viewing them, is rare enough, with a lot of are done by mistakes, so what makes those people think their users could make a decision of purchase, which often takes several rounds of researching, comparing ,hesitating to make the final stride, by randomly scrolling through something might bot even be relevant, is totally beyond me.

Even if the user happens to like the item in the ads, the actual action would come after several hours, do they expect user to come back to app, find the ad, then click the buy button?
The London Underground opened over 150 years ago, and yet manages to keep up with capacity requirements, open new lines, and generally is incredibly reliable. I'd be surprised to get to a platform and wait longer than five minutes for the next train.

Part of that is because they don't run 24 hours allowing maintenance to take place at night, but I think the biggest factor is Transport for London being a mostly independent entity - they're not required to put money they make back into a central pool, and instead can reinvest it in their own services.
There already exist parking spaces that are for extra-small cars (like Smart cars) only. These will often be cheaper than alternate parking, or at least much more convenient. It's basically the exact same thing - a parking advantage offered because a feature of the car allows for it. In one case, size; in the other, automation.
The short answer is no, for a couple of reasons. First, you have to distinguish whether you want the antiderivative or the integral. In the first case, the problem with finding the antiderivative is that it's not unique. For example, the antiderivative of x can be 0.5 * x^2 or 0.5 * x^2 + 1 or 0.5 * x^2 + 2, etc. Basically, taking derivatives can lose information and we don't know how to put that information back. In the second case, we have the integral, but that creates problems because the integral really needs to have a domain defined to make sense. Basically, over what values are we integrating? In 1-D we can specify this with a bunch of intervals, but in 2 and higher dimensions, it becomes difficult. In fact, this is partially why we have meshing tools like Cubit or gmesh. Yes, we use them with finite element methods, but really, at it's core, we need them to break up a domain because we want to integrate the pieces.

Anyway, with enough information or on a simple enough setup, both can actually be done, but the general case isn't super well defined, which is why the simple answer is no.
10 Secrets of All Successful Blogs: Revealed
I find it quite disturbing that not a single allegation is properly sourced. "According to knowledgeable individuals" means absolutely nothing. Not a single journalist would dare make such accusation on such a thin basis, especially since what follows are not facts but opinions.

This only shows what someone (an analyst ?) in the State Department thought were the French Motives for Overthrowing Qaddafi (one overthrows a ruler, government, not a whole country).

Whether he was correct or not isn't very easy to establish, given the absolute lack of supporting information on most of these points.

Re-asserting the position of the French military is far fetched, for a president that cut its budget and size very significantly. Similarly, claims about influence do not seem particularly credible given the utter lack of follow up and French presence in the country after Qaddafi's death.

The only credible point really is c., a desire to improve his popularity at home.
I'm curious what happens when there are two dozens of these in an active parking lot (or near each other on a highway) and they get false sensor echos.

Then one day there will be half a dozen brands with slightly different sensors messing with each other via accidental interference and echos.

Public has no idea how this stuff works and starts putting a little too much faith into it can lead to some horrible accidents.

The main difference is that gecko with the web apis to access hardware features provide a very nimble layer that makes quite easy to develop apps with JS that previously could only be developer with Java or Obj-C/Swift. Its like phonegap without wrappers.

Imagine if your web app could directly talk to hardware sensors, disk and phone features if the user gave it permission.

The difference is that blink does not offer such APIs not this tight integration with the OS to the point where gecko is the OS. It used to be called "boot 2 gecko" for a reason
Ah I definitely should have qualified my statements -- I was thinking more fridges/microwaves/things with screens. Most of the benefit is that they don't have to try and build some frankenstein of a view layer if you go with FFOS.

FFOS is definitely just about useless for IoT applications if it doesn't have a screen -- I completely agree with your point, it's just a fork of AOSP at that point.

Please document your judgement.

I'm usually one of the first ones to detect horse shit in women-victimizing papers, usually by matching statistics with reality. For example, given that I've seen many (if not almost all) women in my programming environment being promoted to "managers" earlier than men, statistics about women being paid less in IT "for the same experience" get discredited by the fact that a "manager with 1 year of experience" is not the same when he's had 7 years as a developer under his belt or when she's 24 years old. Studies rarely specify "with the same experience in the current and previous job". Besides the fact that studies are inherently false if they don't explain why women get promoted a lot a lot a lot in the reality I'm witnessing.

So you see, I'm open to be on your side. Just in this case, I didn't detect how this study could be biased. Please document, thanks.
The sad thing is that lint was created in 1979, already when C unsafety was clear.

However in the early days, only C was being ported outside UNIX (parts of it actually) and lint became something that only the ultimate versions (to use a more modern expression) had.

There was also the issue of false positives.

So very few bothered buying it.

No, the problem here is that the word ALGEBRA has two meanings, in high school vs college+ contexts. They share the same name and in both you can state that ax=bx => a=b ... but the similarities end soon after.

The material here is precisely what you'd expect in your first (i.e., basic) college algebra class.
> So if you're a marketer with a budget, where do you allocate it? Put it on Google or Facebook, where there are tons and tons of users where you can target very well? Or on Pinterest, which is a much smaller audience, female, lower-income, where you can't target well? It's just not as efficient."

This part is really interesting considering how other tech companies put a huge amount of effort into acquiring that exact female crowd from their mostly male mid-to-upper crowd.
As an European I find it horribly annoying to have to tip in the US. If I do not like the the food I still have to tip because otherwise the nice waiter gets nothing? Or is that old information? Or was it always a lie? I only want to tip when I really like something, not as a kind of guilt trip with an unwritten minimum. Wish they would change that.
Yeah, and watch out for the word "Elementary". Mathematicians use this word to mean "can be understood by a single person". This in contrast to the kind of maths that leans on other difficult maths so much that no one person can figure it all out. That mathematics is the non-elementary kind.
> I've personally run tests and seen tests achieve statistically significant (and very large) results that weren't merely fixing bugs or moving buttons within reach of a user. It could be things like adding a modal, changing copy (yes, literally just adding or changing words on the page), removing content, changing an image, or reordering funnel steps.

You should read the article. It explained very well why a) statistical significance is meaningless when split testing websites (you are guaranteed to archive significance if you run the test long enough; the math behind significance testing doesn't work like assumed by Optimizely et.al.) and b) most tools on the market are inherently unable to prove effect size by the way tests are designed.

Just do this short experiment yourself: Do an a/b test with identical versions of you site. Spoiler: With 100% certainty, you'll see both significant results and a sizable effect size difference.

Under the Hood of Redis: Hash [Part 2] and LIST
To be honest, as a French person I didn't see anything new in this cable. None of this was secret, it was pretty much the official stance, except stripped of the humanitarian aspects such as the ongoing civil war and repression or the Arab Spring.

It feels like Hillary's advisor was merely watching French TV and transcribing what journalists and politicians said publicly. The mention of Bernard Henri-Levy proves it. When you sum up a geopolitical situation in a few sentence, you don't waste any explaining BHL is a "semi-joke", unless your own knowledge is cursory.

With regards to the French population, you have to put it in context (April 2011, see https://en.wikipedia.org/wiki/Timeline_of_the_Arab_Spring ). The Arab Spring was still going "smoothly" elsewhere, and we were all watching Egypt, Tunisia, Morocco, Syria and Algeria where things were handled "more or less peacefully" back then, at least to the French eye. Qadaffi's repression, on the other hand, was violent from the get-go.

It was a perfect storm (1) for Sarkozy, as on top of the things mentioned in the cable, he had to prove that he was serious with his Mediterranean Union, and more importantly he had to disprove the allegations that Qadaffi financed his election.

Wether it was the right thing to do or not, I personally have no idea, but it was pretty much a no-brainer at the time for France to distance itself from Qadaffi during his civil war, and fuel the opposition.

(1): unrelated, but maybe I should have said "homerun" in this case? My English fails me.

Ask HN: How does a 1990s web developer get back on track?
During the late nineties I was making various interactive/dynamic websites using the then standard technologies: HTML, PHP, Perl, Mysql, and a tiny bit of CSS. This was the time when Javascript was really only used for form field validation and to spawn popups (Ajax was not yet around), when all layout was done using borderless table/tr/td HTML elements, when there were no mobile devices and all you had to care about was one or two screen resolutions and basically two browsers: Netscape and MSIE. Since then I have been pursuing my IT career in a different area. But sometimes I still find myself wanting to setup a website every now and then. But in the little free time I have available, I stumble upon all kinds of web technologies and frameworks: JQuery, Node.js, Ruby on rails, AngularJS, Backbone.JS, Django, Bootstrap, to name a few. Ofcourse all have their purpose, weaknesses and strengths. But after work and family, there isn't much time left for exploring and trying new things. Maybe other people have already made this journey and can share their experiences? What would be the best way for a nineties web developer to update his knowledge and skills?
Eh given the constraints as you spell them out it seems a clear at the release moment driven by a shader could work.

I rented a Ford Focus in France at the end of last year which could park itself either in a car park (i.e. cars parallel to each other) or parallel park at the side of the road.

I tried it parallel parking on a bend with a big drop next to it (so no walls to figure out where it should stop), and once I figured out which button to press it worked quite well.You still have to manually shift from forward to reverse (when it prompted you) and use the brake, but other than that it's hands off.

The best feature of this car wasn't this, but the technology that powers it - sensors all around the car to detect how close you are to something. It had a small indicator on the dashboard to let you know the distances.
When you see Lemma/Proposition/Theorem think of it as an API that you can interface with.

Skip the proofs on the first read (this is the implementation, and may or may not be enlightening.)

But, number one rule with learning maths is: you got to do it yourself. Play with it somehow. It's similar to learning a new (or first) programming language (or API): have a project in mind and try to do it using that language.

Seriously, you absolutely cannot learn this stuff just by reading. Or, at best you may learn a very small fraction of it.

IMO, this text is far from "typical definition-theorem-proof". There is plenty of other prose and examples there aswell.

It looks like we more or less agree, and the point of disagreement is the components of love, of which I think there are two: attraction and companionship. It is possible for a 50 year old husband to feel tempted to sleep with an attractive 25 year old who is trying to seduce him, while feeling deep love towards his 50 year old wife, who is now a lot less attractive than when he married her. He can feel tempted to cheat but at the same time feel bad about betraying his wife. Should they divorce? I'd argue in many cases, no.
This is a lazy blog post, and I hope this isn't used as a launching point for further discussion. The article in question is many times more substantive, and alexandercrohde rebuts with a caricature and no facts to anchor upon.

I'd also say that when people say things I don't understand in a domain that I'm interested in, that's normally a sign that there's a gap in my knowledge. Of course people bullshit competency, but I doubt it's through verbiage alone. Almost all the time, when I later go back to read what people were talking about, I come to understand that they were not bullshitters. In my experience, people who can talk in a complicated way without knowing what they're talking about are exceedingly rare. There are a lot of smart and knowledgeable people all over, and it seems almost impossible to hide behind complicated speech, hoping nobody knows that you're ignorant.

People might have a mean attitude of "Either you keep up with the lingo of the field or don't", but that doesn't mean they're bullshitting. And it's better to use an established "25 cent" word than your own idiosyncratic "1 cent" word. I mean, how else is that person going to Google or later verify what you're saying?
