Uber Black perhaps, but not UberX, which is by far the focus of Uber now. Around here Uber specifically advertises UberX as a taxi, and openly does price comparisons between it and taxi fares (as opposed to price comparisons against other limo services).

Let's also not forget that Uber started as Ubercab and was forced to change their name. I don't think they ever intended to be a limo service, and their current product offerings are largely not limo services.
And...? I'm sure it is. It markets their product at the expense of their user's credibility with their social circles. There's no downside! (For Sumall)

It seems like I see these articles pop up on a regular basis over at Inbound or GrowthHackers.

I think the problem is two-sided: one on the part of the tester and one on the part of the tools. The tools "statistically significant" winners MUST be taken with a grain of salt.

On the user side, you simply cannot trust the tools. To avoid these pitfalls, I'd recommend a few key things. One, know your conversion rates. If you're new to a site and don't know patterns, run A/A tests, run small A/B tests, dig into your analytics. Before you run a serious A/B test, you'd better know historical conversion rates and recent conversion rates. If you know your variances, it's even better, but you could probably heuristically understand your rate fluctuations just by looking at analytics and doing A/A test. Two, run your tests for long after you get a "winning" result. Three, have the traffic. If you don't have enough traffic, your ability to run A/B tests is greatly reduced and you become more prone to making mistakes because you're probably an ambitious person and want to keep making improvements! The nice thing here is that if you don't have enough traffic to run tests, you're probably better off doing other stuff anyway.

On the tools side (and I speak from using VWO, not Optimizely, so things could be different), but VWO tags are on all my pages. VWO knows what my goals are. Even if I'm not running active tests on pages, why can't they collect data anyway and get a better idea of what my typical conversion rates are? That way, that data can be included and considered before they tell me I have a "winner". Maybe this is nitpicky, but I keep seeing people who are actively involved in A/B testing write articles like this, and I have to think the tools could do a better job in not steering intermediate-level users down the wrong path, let alone novice users.

Great! Finally companies will have an incentive to give themselves sensible names.
I saw it more as a rehash of Michael Porter's idea that you should compete to be different rather than "better", instead of the approval of monopolies that many people have seen it as.
GitLab B.V. CEO and author here, thanks! Please let me know if there are any questions.
It seems like every time I see Uber in the news they're being assholes in one way or another to their customers, drivers, competitors, and governments of all types.

The ends don't justify the means.
"Honestly, in a website A/B test, all I really am concerned about is whether my new page is better than the old page. A one-tailed test tells you that."

No, it's the other way around. One tailed test is only usable for testing if the new design worse than the old one, because it being better than the old one does not matter as long it's not worse. If you are testing that is the new design better, you definitely need to test both tails or else you may likely switch to a worse design than the old one.

If I can measure your priorities by viewing your site, it appears that your #1 priority is a certain look-and-feel (as dabeeeenster put it "photos of hot 19 year old girls on a beach"). Along these lines, you have also purchased "circle.com" - do you read Dave Eggers too?

Your #2 priority must be investment, since the "Management", "Board", and "Investors" sections of the site are the only ones that contain any actual information.[1] You have some impressive backers and impressive funding. In my experience, companies that are more excited about how much funding they have raised are less likely to succeed than companies that are excited about the product they are building.

To sum it up: I am unimpressed.

[1] - Learning that you are "excited about bitcoin" isn't information. Because of that excitement have you decided to offer bank accounts denominated in bitcoin? To offer a tool allowing merchants to accept bitcoin for daily purchases? To create a new offering that will supplant bitcoin? Look -- we're ALL "excited" about bitcoin: it's an interesting innovation. Being excited about it isn't news.
In my experience Optimizely does everything they can to mislead their users into overestimating their gains.

Optimizely is best suited at creating exciting graphs and numbers that will impress the management, which I guess is a more lucrative business than providing real insight.
in uber we trust.??
The service provider is not a human, its goals are not those of humans. It provides you cheap service because it's weak, it needs to feed in order to grow stronger, to fight the others of his kind, money-eating beasts we call companies.

Don't think for a second Uber will continue to provide useful service at fair price when it finally grows mature and stifles its competition. With its continued disrespect for human values, such as honesty and decency, it already shows us the shape of things to come. We know this beast will not be friendly to men.

Uber needs to be slain now, while still young and weak.
Agreed on it still being vast.

I think I am just taking (unreasonable) exception to the term of heuristic here. Yes, naive brute force would have you look at about 10^7 positions for the classic 8-queens solution. However, there is no need to do this. Dancing links drops that number down to just over 10^3. Without sacrificing correctness/exactness.
Sorry I forgot to qualify my comment in that I think its a great solution for startups who are comfortable with SQL and a little bit of coding to glue a system together.

I have also conflicts about this. I realise that some of my frustrations have origin in the definition of "meaning" we have. I think is a mistake to associate "having a meaning" with "being permanent". Things/people/experiences do have a meaning, i know it, and feel it. But they won't last and that's what bothered me. Working on it.

Yeah, no. 99% of admins do not use strong passwords. That's the reason we have brute-force dictionaries: they usually work. Besides, almost all systems still use the weak old encryption routines that can be brute-forced in a trivial amount of time with modern hardware. There's a small handful of systems which use a modern password hashing method for their secret files.
I'll try to give a short answer, but suppose for the purpose of this discussion that Haskell and Erlang both address the project's initial code concerns equally well. Large, dependable projects, with a long projected usage, have some general requirements that are well-known and tend to be the same for most of them. They include ease of training, ease of hiring, ease of reading and modifying other people's code, ease of upgrade, ease of debugging, ease of profiling, ease of monitoring running software and more. In short, ease of maintenance. Languages built by the industry and designed and used by industry tend to put a lot of emphasis on this, while languages built in academia tend to care more about language expressiveness, code reuse (through graceful abstractions) etc.. Those are important things that matter to the industry too, but not nearly as much as the ones I mentioned. Because language maintainers have limited resources, often one set of requirements comes at the expense of the other. Sometimes the concerns in the latter group can even directly conflict with those in the first; for example, powerful abstractions can become too clever, hard to learn, and hard to understand by reading the code (I think this might be the case with Haskell, but not necessarily so for any hypothetical "academic" language).
Can't speak to this exact situation, but like the parent said:

My comment was from the perspective of course of life. After retirement, he had only 5 years to pursue "his passions of outdoor photography and protecting the environment". (Note that he did not continue working on his research.)

He was under pressure to deliver results (school, working, etc.) for the majority of his life, and he had only 5 years of total and independent (within financial constraints) freedom. That is sad.

My University uses Moodle, which is also TERRIBLE. I do all my grades and such in Google Docs, since Moodle is a UX nightmare. Something as simple as entering grades in Moodle requires a lot of clicking around for each grade. We have multi-page documents describing how to perform even the most basic tasks, they require constantly clicking and going to new pages of indiscernible icons. Menus are impossible to navigate without help.
Open source doesn't do anything to help with this kind of stuff. Not one thing.

Suppose, for the sake of argument, that Facebook released the full code of their social networking application under the GPL. That promises us very little in terms of our privacy, because they could easily (and perhaps should, from an engineering standpoint) stick all the privacy violation in a separate application for doing the analytics or providing data to 3rd parties.

Open source doesn't even do much of anything to limit what kinds of data can be collected through the front end. The original owner of the code retains copyright, so open source licenses place no legal restrictions on what they can do with the code. There's nothing stopping an unscrupulous company from sharing a squeaky-clean version of the source with the world at large, and running different code on their servers.

If anything, this is where I find Stallman to be at his least useful. He's only got this one hammer in a world where the vast majority of the most worrisome ethical concerns are not nails. His dogged insistence on trying to turn every moral and political issue in computing into one that can be answered by open source[1] is neither realistic nor practical, and only serves to illustrate that his ideas all became fixed long before Berners-Lee came along and changed everything.

Yes, I wear my Nexus 4 on my arm and it's not the nicest thing. I previously had a 4" phone which was much better. Also, the smartwatch is nice to see your speed and the time, so you would wear it anyway (I can't really check the phone's screen on my arm, but I have audio feedback). If you can get rid of the smartphone, which is here just for the music and GPS, that's perfect. An update to android wear is going to bring bluetooth offline music, perfect for my bluetooth headset I use. Why take your smartphone with you when you don't need it?

I'm making the same observation on my site. I thought search would be the clear way to get to where you want to go but it is relatively unused. I have a site which lists tutorials for a specific language. You would think people would be looking for something specific, but it seems 90% click whatever is displayed first and other just surf around using the basic filters and pagination.

I don't think you can call it a pipeline, they only state that the different parts of the instruction are being decoded in parallel. For instance, which instruction will be executed and the register associated with the operation. There is no instruction pipeline.

> control purposes

Here you have an implicit assumption that the system
being controlled can react, that is, in the sense of
control theory, change its plant dynamics, due to the
effort of the control. Well, for a lot of work in
control, say, in most aerospace applications, that
assumption is false or essentially so. Then
getting a good metric and using it is fine.

E.g., get the power spectrum of ocean wave noise
and use that in a control system to keep
a submarine at essentially a constant depth.
We don't expect that the metric of the
ocean wave power spectrum and the control system in the
submarine will change the ocean very much!

E.g., GPS is a terrific metric, but we don't expect
that using it will change the shape of the earth.

Etc.

Probably worth clarifying: I don't think Thiel is arguing for monopolies. Instead he's arguing for lack of competition via differentiation (i.e. if you're the only one doing something, you're going to have a much easier time of it).

Also worth noting is that this idea isn't Thiel's, but is one that Michael Porter has been putting forward for years now. Of course, Porter is read by MBA students and Thiel is read by people who want to do a startup, so that may explain why this idea seems so new to people.

P.S. if you're interested in reading more about Porter's ideas I can recommend two books. The first is Understanding Michael Porter, which gives a good summary of the main ideas of his works. The second is Different: Escaping the Competitive Herd, which doesn't address Porter specifically, but covers similar ground.

The clean approach is to wrap functions into classes:

class Wrap { void call() {...} };

template <typename F> { ... F::call(); }

And with some imagination one can write a macro to do this wrapping given an existing function, used like this:

void my_func();

using MyFuncWrapped = WRAP_FUNC(my_func);

// Now MyFuncWrapped::call() calls my_func.

My implementation of the wrapper: https://github.com/ambrop72/aprinter/blob/master/aprinter/me... . But note it doesn't use std::forward since this code assumes no references being used.
(On the usefulness of) SIMD support in JavaScript
I agree that this false sense of security is troubling. Many inexperienced site owners will think setting up Flexible SSL with Cloudflare is all they need to do. And it is unclear if the enduser has any way to see if the site they are connecting to is using Flexible or Full SSL.

However, in the announcement Cloudflare did say:

" Later today we'll be publishing a blog with instructions on how to do that at no cost. Once you've installed a certificate on your web server, you can enable the Full or Strict SSL modes which encrypt origin traffic and provide a higher level of security."

So this gives me a lot of hope that end to end encryption will proliferate.

What I dont understand is how they will be doing this at no cost. It looks like the certificates being issued automatically are to "xxxxxx.cloudflare.com", and not to the origin domain. Perhaps to get Full SSL you will have to enroll via Cloudflare's website to get a separate SSL that is for your site. This could then be verified the traditional way for Domain Validation certs.

Globalsign and Comodo seem to be the two providers for this.

Is it courageous to leave behind others to pick up the pieces? I know this isn't always the case and I wouldn't call suicide "cowardly", but I might call it "selfish".
Well, I have no problem with making up words, but I feel like mentioning that there is an even more concise term that could be used: "fast".

Although this word doesn't have a scientific gleam or a stamp of enterprise approval, it is actually more specific than "performant". Technical words are nice but sometimes they just serve to hide details. All that glitters is not gold.
So what's the point of this project? I mean does it provide anything more than straight mapping "-S" -> "install", "-Su" -> "dist-upgrade", etc. ?

I'm pretty sure philosophers invented metadata, even though they did not give it that name. The question how to distinguish between the properties an object has and what properties we attach to it, is sort of central in epistemology. Higher category theorists sometimes distinguish between stuff, structure and property http://nlab.mathforge.org/nlab/show/stuff,+structure,+proper..., which makes the definition of forgetful functors more precise. Conversly attaching structure or properties are (not nescessarily unique) adjoint functors to those forgetful ones. In mathematics this comes up for example if you consider the category of abelian groups from which there is both a forgetful functor to the category of groups and to the category of sets, but the general idea should be applicable to metadata attached to text aswell.
