With 56 tests and looking at 2 dimensions, having ~6 false ideas certainly isn't surprising even if you calculate to 95% CI..

But despite our focus on the null hypothesis, it is actually just the cost break even to make false conclusions when two variants are equally effective. So you are even less likely to make a mistake in a real A/B test the larger that mistake is going to be and cost.

Emulating statistical theories poorly is the essence of many methods of AI that despite occasionally ridiculous results are quite powerful.

If you instead simply measure your conversion rate of each campaign, you can not tell if you are negatively trending in terms of the content because there will be outside factors of user engagement especially if you lack an adequate source of new subscribers. Only the most engaged humans will pull the signal out of that noise enough to get better over years without an external system. (If I were not going to A/B test, I would at least first estimate conversion rates and then track my Brier Scores over time.)

I don't have any experience with email campaigns, but what I see with web ones is that most organisations are fairly delusional when it comes to understanding their actual audience and communally they are rarely open to accepting corrections from people with less domain knowledge, (but domain knowledge is primarily a fancy form of bias.)

For example, if your product caries risk, many of the customers who contact you will be the most risk averse looking for security, but 95% of your customers will probably be risk tolerant. I've repeatedly corrected some via an A/B test where the B versions conversion rate continued to apply long after it became the only version, but their staff will implement A style changes whenever given an opportunity to do changes without testing. I'd guess that customers they deal with give them a false impression and our repeated demonstrations that there are significantly more customers with a different view is not an adequate correction.

Not using outsiders it is harder to get such a full corrections to your biases, but you can at least get a new employee's (or spouses or critical customer's) idea tried out in a way where they are much more likely to quantitatively show promise in way that demands acceptance rather than being chalked up to noise using the human emotional system.

I'm sure this bias has a name? The idea that changing the outcomes for the better is actually worse because different people are affected.

The point of the parent was that for commuters, for long-distance cargo transport and for busses some "super lane guide" would be useful.

Does your going into the mountains contain "driving on the same lane with thousands of others from the same place to the same place every day"?

Because that’s what I was suggesting – nothing more, nothing less: Replacing mass-scale commuting with rail.

Yes, if you drive somewhere where no one else wants to go, cars are still useful – but if you’re going the same path that another million people are also taking, maybe rail might be better.

Rail and Road are not exclusive, they can coexist.

While the news article didn't describe the percentage of people "harmed" by using a temp company, it did give examples including the Teamsters / Leadpoint / Browning-Ferris case, it described that it was a non-trivial fraction of people affected, and it explained the rule change for to do things differently. It also linked to the actual decision, at https://www.nlrb.gov/news-outreach/news-story/board-issues-d... , so you can read the full details. That in turn says (emphasis mine):

> Consistent with earlier Board decisions, as well as the common law, we will examine how control is manifested in a particular employment relationship. We reject those limiting requirements that the Board has imposed— without foundation in the statute or common law—after Browning-Ferris. We will no longer require that a joint employer not only possess the authority to control employees’ terms and conditions of employment, but also exercise that authority.

As most people aren't unique snowflakes when it comes to mate preferences, the likelihood of being the only woman fancying a certain man is low. With Tinder women trade the obnoxious problem of heaps of unwanted attention for the less glaring but quite insidious problem of letting the eligible bachelors know exactly how well off they are. With OkCupid, these men play the same game as everybody else, just with more success. At Tinder they have an exact count of how in demand they are, giving less incentive to commit.

Really? For me, a chain of maps and filters is far easier to understand than nested for-loops or something.

I think it's a lot to do with exposure: imperative code is far more well-known, and most people are more exposed to it than they are to more declarative stuff. I'd say that if someone was exposed to both equally they'd find the declarative easier to quickly scan and understand.

"Freedom of speech" doesn't mean the power to not be moderated by an Internet forum, it means that you can speak your mind and your government can't arrest or censor you for it. If someone invites you into their home and you start calling their family names and pissing all over the carpet, the homeowner is well within her rights to throw you out and shut the door on you. Similarly, if you go onto an Internet forum that is owned by someone who is not you, they can moderate you into oblivion because it's their forum.

> On HN you also can't really say many things cause it is moderated, I've experienced it many times that people will just try to ban/downvote you into oblivion instead of discussing anything.

That is the community doing that, not the owners of HN, so I don't understand why you'd have a problem with it. You are free to post what you want here, and other users are free to up/down vote you, or reply to you, as they see fit. That is the very freedom you're crying for here, right?

I get it though: You want a fully unmoderated soap box to say whatever you want and don't want anyone to censor or moderate you. You're never going to get that using someone else's forum, so the solution is simple: Build your own! Buy a domain, learn to code or use a premade platform, launch a VPS or CoLo box, and post to your heart's content. If you are able to build an audience and get people to listen to you, great. If you choose not to censor or moderate your users, great. But I think your eyes will then be opened to exactly how difficult it is to maintain an Internet forum without some sort of rules and moderation.
Think about it this way. Imagine there's a hypothetical medical device X. It has been calculated, that due to operator errors, this machine on average kills 1/1000 patients. Operators are given more training,but the average does not change.

Now. Another company makes an automated machine, which kills 1/10000 patients on average, because of software errors. Do you think anyone would ever allow the second machine to be sold, even though it would save 9 persons compared to the manually operated machine? Of course not. If it ever came to light that it killed anyone due to a software error, it would be gone faster from the market than you can spell "liability". Does not matter that in fact it's killing less people on average than any other type of machine - it's just that in our minds software bugs are avoidable so therefore they are not acceptable at all.

Actually nokia had an iPhone like device in 2004(whatever that means, not a lot of details, understandably[1]) but: “It was very early days, and no one really knew anything about the touch screen’s potential,” he explained. “And it was an expensive device to produce, so there was more risk involved for Nokia. So management did the usual. They killed it.”

Apple faced a similar decision - an expensive device, that wasn't a sure success(at least in the beginning) - but they could leverage their iPod customers and their music libraries to get an initial market for the device - and than use that power together with a smart strategy(playing carriers against each other, which was hard for nokia) to fully control the phone - what enables a very different app store dynamic .

Couple that with Apple's deep understanding of brand building and marketing ,one gets the notion that nokia lost to the iPhone less because of not seeing the future, but more because Apple had better resources and skills and just played a better game.

And why did Apple lose to android ? due to the same reason - Google is far better at software development + Open source phone financed with ads fits Google very well.

Well... no thanks. :)

Wordpress has some undeniable qualities for quicly building simple websites. Making it a whole framework for apps and big websites just sounds silly to me.

If I need to build large webapps I don't see any reason to do it with Wordpress (or even PHP) nowadays.
No more mocha, tape, Qunit, intern, Jasmine, Unit.js, Sinon, Buster, Chai or Wallaby.js. This is the best.
Apple's app store is still in its hands. And because of the fragmentation of the app store, people are more inclined to download app from the website of the maker instead of some "store" that injects "non-kosher" stuff in the app
What does ZFS have to do with this? This is like any other properly executed backup. You may as well call it "defeating having your day ruined by keeping proper backups". Granted I do like ZFS and I've literally been doing this for ages, backing up my KVM guest images to ZFS SAN the KVM host can access to save the snapshot and the KVM guest can't access at all.

However this can be done a million different ways. It's just a backup not accessible to the affected system... I do the same thing with my bare metal OSX machines (macbook, macpro, etc...) they use time machine to backup to Netatalk shares, those shares are image files which again get backed to the ZFS SAN. So even if the time machine share was encrypted I'd have a copy of the image holding the share from X days ago.
I've been disabling by default for a few weeks, though many sites still use it, for example:

- Facebook (videos)
- Twitter (bizarrely uses it for gifs in Firefox)
- YouTube
- BBC news
- The Independent and most of UK press
- Basically any site with embedded video
- even github prompts because of that copy+paste feature

I have no interest in Flash games or adverts, so it's annoying that these big sites all still use Flash.

> Have you considered what it will take to provide row/column level controls?

FWIW I did this for a client application and it wasn't real fun. Took a few tries to come up with something that was reasonable at column-level resolution.

Figure you need at least read and write permissions, you need to have table-level granularity, you want to have column-level granularity, you want to make it easy to manage groups of permissions (roles), but you also want it to be easy to create users with exceptions to those roles. For example, how would you create permissions for a group that gives you access to all of a table except a specific column?

You need, basically, ACLs, and afaik there isn't a standard recommendation for that yet (that I could find).

I settled on a roles table and a permissions table, with descriptors with wildcards for different operations (like, "read-client-address", "write-client-notes", "∗-client-∗"), and allow/disallow/inherit options. For instance, a "demo" account has "disallow ∗, allow read-client-∗, disallow read-client-name", etc. On login the permissions are loaded for the user signing in and then each DB operation checks to see if the operation is allowed() in a function that resolves wildcards and priority and does a few other tricky things.

There are probably better ways to do it, but anyway, the moral is that there should be a good reason for needing more granularity in permissions before someone decides to implement it.

Or, putting on my tinfoil hat, they already have means to break arbitrary encryption and they just want back doors (public or in secret) to provide plausible deniability of that fact. An important aspect about having an exceptional capability is not revealing you have that capability.

An interesting possibility for Uber in China, assuming they "win," is that the timing could work for leapfrogging car ownership.

The timing is right for that in china. They're just entering where more centre of the curve people can afford cars, but most don't yet. It's not ingrained in the culture yet, so they will be more open to alternatives.

Also, with driver salaries are lower in China that US & Europe and that will reflect in uber prices. This means that the uber/private car equation is more weighted in Uber's favor.

Between those two things, it gives uber a decent shot at becoming a top tier mode of transport.

The crazy thing about the market Uber is biting is that it is a massive, massive market. Once you start talking about about market share in transport, you are in crazy territory.

Side note: It's pretty wild how much money is available in the "private" markets these days.

So, I agree with other commentors that (1) the scale of money coming in is confusing the definition of "startup" stage and (2) I agree that the risks are pretty substantial. That said, (A) the potential reward is pretty hefty too and (B) they seem to be actually operating as an enormously oversized startup. They're taking startup-ey risks and developing the product-market in a startup-ey way. IE, it seems that their current form is not their medium term goal.

Say what you will about Uber, they have balls.

"What would be other important things to ask/consider."

1. What do _you_ think the company is worth today? If your net worth were $250m, how much would you be willing to pay for 100% of this company?

2. Does the company have any debt? If so, subtract this amount.

3. What rights are attached to the different classes of shares (e.g. liquidation preferences) and which class of shares will you be issued?

4. Based on what you learned from (3), what % of the exit value will you get if the company is sold next year for what the founders believe to be the current valuation? What about if it's sold next year for what you believe to be the current valuation?

Re: #4, the % will probably differ based on the sale price and how far into the future the sale occurs. The sooner the sale and the higher the sale price, the less of the total value you will lose due to liquidation preferences and/or other additional rights attached to investors' shares. If the sale is very far in the future, liquidation preferences could totally wipe out your equity, even if the sale is at a decent price.

Le Tote (YC S13) Is Hiring a Full Stack Growth Engineer
This is a review by Galen Strawson of the book by Nick Hume.

I agree with Strawson's thoughts about the cause of outrage and offence not being narcissism but "something vastly more toxic: righteous indignation felt on behalf of others".

"righteous indignation felt on behalf of others – typically a group with which one identifies or sympathises. ... It’s precisely because such righteous indignation is not narcissistic, and is not experienced as mere self-concern, that it comes with a feeling of absolute purity – purity of cause and of justification – that seems to license absolute violence.... the anger is cleared to express itself without inhibition."

Group psychology - The defence of the group will always come before the protection of the self. Having a group behind you allows your actions to be justified - no matter how badly behaved, aggressive or morally wrong - because the group justifies these as right and good.
I think you're supposed to call them mentally handicapped.
