It's weird to me that Google fails, hard, on so many ui things.

Here's one example from the Gmail app on iOS, from the feedback screen.

http://imgur.com/a/koKRb

The [done] button is where the [return] button usually is; and it's directly over the [send] button. So if you don't notice that return is now done, and tap it twice to get a new paragraph, you just sent your unfinished feedback.

I blame Google, but it could be Apple being stupid with the dreadful iOS keyboard.

> possible to get a pretty good impression of whether the user interface was thought about or rather just an afterthought.

I'm sure Google spends a lot of time and money on the UI. Which just makes it more frustrating to me. EG Chrome's (on iOS) address bar does not let you select and copy an address until the page has nearly finished loading. And to paste an url into the bar you don't tap the cursor but some mid-point of the address box - except it's flat UI so you just guess where to tap. Items in the burger menu take five seconds to become clickable.
Surface tension is magnetic attraction between molecules. There's not enough negative magnetic attraction to hold them; they're repelled by all the other molecule nuclei.
The issue of bringing anything like Docker (app virtualization) to RHEL/CentOS/SLC/CERN/Rocks 6.x is supporting an old kernel, adding custom-compiled kernel modules or compiling a custom one. I had this exact conversation with some clients whom I did some hypervisors work with and whom recently sold their startup to one of (VMware, Citrix, Microsoft). In fact, about 1-2 years ago we joked they should've bought dotCloud (now Docker).

PS: Docker is a prime example of how a side feature can be instrumental to a pivot to something much larger.
Fair enough. I've reworded that part.
I thought it was just pressure - the more dense molecules push the Hydrogen out of the way as gravity pulls at them.
My brother still plays Subspace and he was on the beta in '96. Something about that game brings out the meanest streak in humanity, though. The comments are often hilarious, you can almost hear the other guy snap his keyboard in rage.

Great, balanced mechanics, though perhaps that's changed. I'm thinking of the old Chaos and Capture the Flag zones. Can still hear the sound effects as I'm typing this.
> That's still like a couple of degrees (4 full moons) away so not sure how accurate it would be.

It depends on how the two tilts interact - do they cancel or add? I don't know.
One of the most telling points is from /u/imakuram, moderator for /r/books:

"This seems to be a seriously stupid decision. We have several AMAs upcoming in /r/books and have no idea how to contact the authors."[1]

They really shot the communities in the foot by not giving them any notice or support. Given that the key feature in ensuring the quality of Reddit is the moderation "donated" by the community, this is a deeply dangerous move, especially as many of the moderators are already irritated.

If Reddit forcibly take control of the subreddits, I'd be surprised if we didn't see a Reddit civil war.

> For what useful definition of deterministic?

The definition that says the future state is entirely determined by the present state. That's the only definition I'm aware of.

>the state evolves in a predictable way from "god's eye", not from the perspective of the experiment occupying any given branch.

The entire "god's eye" state is the one that appears in the dynamical laws of QM (unitary evolution), so that's the one that's relevant for assessing determinism.

> the state evolves in a predictable way from "god's eye", but not from the perspective of the experiment occupying any given branch.

This "apparent randomness" of measurement results is equally true of chaotic classical systems; it's not something that only appears in QM. Basically, it's just a consequence of the fact that individual "observers" will in general not have complete knowledge of the state. That doesn't mean the state doesn't evolve deterministically; it just means the observers don't have complete knowledge.
mega white knighting if I've ever seen it.
I'm kind of disappointed by the cynical tone that has been increasing on HN over the past year or so. This is a straightforward blog post that is transparent about a wide range of technologies used in several areas (not just the user-facing portion). I found it informative. For example, it validates some of my concerns about scaling using PostgreSQL. They're using a single write server in a top 2000 site (according to Alexa).
Fun link. I was planning on similar setup using a couple of remote linked Celestron C8s separated by 5 miles to observe thunderhead cloud formation in SW Florida. Average natural IPD is around 64mm so it should be interesting to see what the occipital lobe does when this is expanded to over 8km. (IPD = InterPupillary Distance; eyeball separation)
Alexis is not helping matters either: https://www.reddit.com/r/SubredditDrama/comments/3bwgjf/riam...
Which is the number of 0,1 sequences of length n that contain two adjacent 1s

It sounds a lot simpler than that. There are n-1 places to put the adjacent 1s. For each of those, there are 2^(n-2) ways to complete the sequence with 0s and 1s. So the answer should be (n-1)*2^(n-2).

Edit: it isn't quite that simple, I'm counting sequences with multiple pairs of 1s multiple times.

By the way, Mathematica's formula looks a lot like the closed form for the Fibonacci sequence.
For Safari (and Chrome) I made a little automator service that gets the url from the browser, strips the hostname, then feeds that into a shell script that calls pass and puts the password in the clipboard for 45 seconds.

It actually works better (for me) than 1password which was always a little flaky at recognizing a website after any kind of site update.
It's funny. Even though I got the right answer, looking back, I still see many holes in my tests. I only tested positive and negative integers. I didn't even think to try fractions, decimals, hex values, text, etc. and I was already expecting a confirmation bias test.
Jesse Jackson had an AMA that did not go very well. Several of the most upvoted questions were simply disrespectful. The Reverend's answers were mostly boilerplate and often unresponsive to the question. The AMA seems to have been part of some PR rollout -- Mother Jones had an article three days ago about Jackson taking on Silicon Valley. The event seems to have failed the rollout's objectives.

Not a great moment for anyone: The AMA didn't always feature the Reddit community at its best, but the Reverend didn't show at all well under the spotlight of Radical Transparency.

Given all that, the timing and speed of the admin's firing hardly seems coincidental. Reddit seems to have blown up a number of ongoing events, and upset an important chunk of its community, which hardly suggests that her firing relates to some long-term issue.

I can see why Reddit might feel the event wasn't handled well.

But it is also very plausible that Jackson and his camp were deeply embarrassed, and insisted that someone be punished for that. So plausible, in fact, that I think Reddit really should give some account that demonstrates that this is _not_ what happened -- or admit that it did.

It is very surprising that this whole thing hasn't gotten more coverage in the tech press.
I liked this puzzle. It got me. I am thankful for it.
mhomde, your comment is dead.
How do you manage referential integrity?

If you have 2 tables, A and B, where B references A
Ideally I couldn't set deleted on row in A until all the rows in B that reference it have also been set to deleted.

If I wasn't using soft deletes, I'd just use a foreign key from B (a_id) to A (a_id), but with soft-deletion, that constraint doesn't get enforced.
I wonder if Reddit is big enough to survive these kinds of recent outcries [1], or if it's destined to go the way of digg, etc.

[1] Only a week or so ago there was a huge outcry about censorship, which resulted in a lot of negative personal information being posted about the current Reddit CEO. Now we have this.
> Due to an unexpected Reddit administrative personnel change /r/science is temporarily private so that we can resolve the situation, our apologizes for any disruption this may cause.

The doublespeak is weird. If it's a protest, say so. There's no direct relation between the employee getting fired and a subreddit that is not focused on celebrity PR going dark.
On the equator the sun could be directly overhead - so you have no idea what any directions are, the sun is equally far from all horizons. (Remember the sun does not move on mercury.)

If you are on the equator, but not directly under the sun then you can figure things out.

I guess I should have said equator on the central meridian.

Edit: I was under the mistaken assumption that Mercury is tidally locked.

So it would sort of work on the equator as well, but you might have to wait a bit for the sun to move enough to tell where you are.
It hinders growth paths and stops reuse that would lower the bar for spreading secure e-mail support.

AGPLv3 has license restrictions that are unacceptable to many or maybe even most companies, and secure company e-mail would be a great first growth application. Even for personal use easy 3rd-party deployment by hosting providers would be desirable, but AGPLv3 may be of concerns for these hosts for a fringe-application.

AGPLv3 also prohibits code-reuse in most contexts, so it makes surprising reuse of sub-components less likely. Stopping this reuse is a shame since it could have reduced the bar for implementing secure email support in more e-mail clients.
DataDog is more of a fully featured application. We want to be a platform for people building custom monitoring, DevOps, and sensor data applications for their needs.

As for cAdvisor, my hope is that it gets updated to work with the new InfluxDB API

Ask HN: Why would you use codility?
This is a serious question. Codility has too many flaws in testing a candidate's ability. Why would you use a service like this?
I'm not sure exactly what you mean by "integrate," but you can have gpg-pinentry use keychain to remember your gpg passphrase for pass.
I'm pretty certain AMA disasters do not qualify as fireable. And firing the facilitator with a history of good AMAs for that reason is hardly an appropriate remedy even if that is so.
> Slaves, gold and ivory were the only trade goods Africa had

Is this bit true? I thought they also traded wood to the Arabian peninsula for instance. Granted, my knowledge here is coming from an episode of CrashCourse[1] and my knowledge of pre-colonial Africa is woeful.

Why? The mods of several subreddits hosting AMAs have been left high and dry, and there were posts from PR agents saying that they'd flown clients around and made arrangements only to have them disappear.

I'd say that this is the beginning of the end of reddit but I just don't know what will replace it.
>I'm from Canada and people fight with the gov't all the time over the coverage of medical care and drugs.

I'm from Canada too, and yeah, the system isn't perfect. Generally conditions which require a more intensive and personalized long-term care (read: expensive) are lacking. Drugs may be expensive. Dental isn't covered. But let me tell you, you need to see your family GP? You'll see them without worry. Your GP refers you to a specialist for tests? No charge. Your specialist orders more tests because of a finding? No charge. Surgery? No charge. You're hospitalized for a few weeks? You'll never get a $70,000 bill.

There is a certain freedom in being able to go through all that, even when unemployed, and never think about whether you'll have to re-mortgage your house.
Nothing, but the story in question was simply a hoax.

Well here we are, what are we going to do now? It seems we have gotten ourselves into some trouble. The world’s problems abound, from declining social morality to murder; government corruption and a world economy that is bound to crash; if you’re looking for problems we have bunches. It seems we wound up on the maiden voyage of the Titanic. Have you noticed our ship is sinking?
Relax; all of your trouble is over, your problems have all been solved. This publication is your rescue vessel to the future; all of the solutions to modern society’s problems are here!. Don’t believe me? Is it worth a few hours of your time to find out? What if I told you, saving the future of humanity is solely in your hands, and depends on your reading this? Would that heighten your interest enough to keep going? Well if we are going to save the world from itself, we must get started right now.
You will be inundated with many new ideas, and concepts in this publication. To save us all, you must agree to explore them with an open mind. You will be requested to do some independent thinking. We will discuss many things most people don’t want to think about. The time has come where something must be done, or freedom will end. Welcome to the Free Human Society!
For one to feel superior, another must suffer. This publication proves life doesn’t have to be a struggle. Society can create the opportunity for everyone to find some level of success. Prepare yourself, A guaranteed plan for a person’s peaceful and prosperous future follows! This plan for saving modern society is outlined in great detail for everyone to study. All this grand plan depends on you.
This publication is written at times directly to you. This is my best attempt to persuade you to support the Free Human Society, and save humanity. Therere is much work ahead, but if you make a personal decision to support The Free Human Society, all the promises in this publication can become true. We can secure a wonderful future for our ancestors. If you are opposed to a prosperous and peaceful future for humanity, perhaps you will enjoy reading how the rest of us are going to overcome your influence in our lives.
I am neither poet, nor scholar. I am one individual, trying to survive on a planet full of people. I don’t claim to be any more or less significant concerning the final outcome of the world. We are probably a lot alike, though we may never meet. I’m one person attempting to make my way through life, in an honest and respectful manner. Hopefully, together we can make the world a better place to live while we’re here.
No, seems a one off, your past comments are fine, so is this one, I think you may have tripped a spam filter.

Literacy and user interfaces are not related. Literacy is a tool people use to record and transmit information, which in turn allows people to learn and improve themselves. Software is meant to accomplish a task, the UI being the way you explain to the computer

I don't care much about the process of how paper and bindings are made, I just want to be able to read my book. Most users prefer the software just do what they wanted it to do with minimal cognitive load. Users that can use the software spend less time calling support, and more time happily using the application. If we made software smarter, what benefit would gain vs dumbing it down?
The sun does move on Mercury. Mercury is not tidally locked- it has a 3:2 spin-orbit resonance. I.e., it rotates 3 times for every two times it goes around the sun. This means that the two sides of the planet alternate facing the sun at perihelion.
To save humanity from itself, we must find common ground. It’s impossible to satisfy everyone; therefore we must exhibit matters of certainty. There are scientific facts we may not like, but cannot oppose because they’re undisputable. In the Free Human Society we deal with facts and find solutions to problems. We understand the situation right now, and are leaving our past mistakes behind.
To state this is a tough read would be an understatement; if you think this is a challenge to read, try writing it. As a citizen of the Free Human Society you will have the opportunity to do just that.
How do you convince people to change? This publication is a best effort to convince you change is necessary and possible. In the end you will have a vivid mental image of the plan for saving the future. This is not a time to sit back, and relax. Sit up straight and prepare to do some independent thinking!
We will explore many new ideas. These ideas have never debated. You’ll be given the entire plan for saving humanity, then chose to support, or decline. Please wait until the end to make your decision. I will attempt to influence your decision by making this both informative, and hopefully readable. I’m going to be myself, and hope you like it.
The first thing we must understand is nearly everyone will have equal success in life if given the exact same opportunities. At birth we are all innocent, and exactly equal. Babies have no conception of right or wrong. Babies understand nothing except the feelings they receive from those around them. This is where change in our society will begin.
Here is your invitation into the Free Human Society, (FHS). The Free Human Society, (F.H.S.) is a world-wide network of individuals who’ve agreed to live their lives in an honest and peaceful manner, and respect other rights to do the same. The great hope for the future is that you will agree, and become a citizen of the Free Human Society (FHS). Will you sign this declaration?
All humans declare at this time and forevermore our absolute freedom and complete independence from each other’s influence. We further more accept personal responsibility for our own behavior and agree to protect each other.
I think trigraphs are supposed to be going away in c++17.
What a circus reddit has become. There's probably/hopefully more to this story but still. It will be interesting to see if reddit forces the hands of the biggest subreddits to open again.

Which raises an interesting question, who "owns" a subreddit, the mods? the subscribers? reddit? I also wonder if it's a good idea for a community like reddit to have "public facing" administrators

Many of the biggest subreddits are revolting against the "governing" and gone private in protest, for example:

/r/Iama

/r/science

/r/movies

/r/gaming

/r/history

/r/art

/r/AskReddit

/r/law
You should have at least had transmission oil changed, fuel and air filters changed, brake pads and rotors (I count this because the brakes on an electric car driven by a normal person will last 150,000 miles or more), and probably new spark plugs by now.

Does having "no strong magnetic field" mean no Ionosphere and thus no Shortwave Radio?
Happy to clear this up:

I did subcontract a very small portion of work, which I did eliminate from the number I crunched. On the whole, it contributed less than $10,000 to the total, and as I mentioned, the time I invested trying to make it work actually made it such that I more or less came out even, but not at a profit.

Right now, I'm handling all the work I'm sent personally. I do plan to scale up in the future, at which point, I don't think it would be fair to call myself "freelance" any more.
Battery longevity and replacement cost is a huge question mark right now, for sure. The data so far looks good (degradation is below what's been predicted) but trying to look 10 years out for a car that started shipping in 2012 is tough.
weird, maybe too many subreddit links looks like spam :)
I've never heard the term "hallway testing" before, and I'm assuming I'm inferring its meaning correctly. I'll be using it in the future.
I still read it (programming subs mostly), but I logged out after the censorship fiasco. Reddit has strayed pretty bloody far off course.
How Many miles have you done?

You better change at least the timing belt, transmission oil and sparks plugs if you hope it to keep running well into the future.
You need to understand that for another coder to finish your project that they'd have waste time to reverse engineer your code, and even then they may not be happy with the way you coded it.

Of course this doesn't even account for the time spent doing bug testing, and then maybe cleaning up your code. And this of course assumes that your spec for the project was able to provide say 80% of the features that someone else is looking for to use.

So yes if you're looking for a cash exit you just wasted 1.5 years of your life.

On the flip side you can look at this as a learning experience and maybe draw the following lessons:

- Start with a small side project, and once you figure out what that is make it smaller.

- Real artists ship.

- Don't reinvent the wheel and do something that's already out there.

>The output side of BI is naturally attractive. Everybody gets money. How could that not be attractive?

That's not why I find it attractive. Most people would not be satisfied with a basic income. Most people are more ambitious than that. They'll want a condo, a nice car, a nice TV, a nice vacation. That's why they work for more stressful jobs that pay higher than minimum wage work.

I like the piece of mind BI gives you, like universal health-care does, like social security does. I know that if I get a run of bad-luck or I fuck up, there is a safety net.
The problem with the pure "email me a link" approach seems to be that breaking into an email account gets only more valuable: The rightful user can't do anything if an attacker gets access to his mail account (or even just his mails), logs into the service secured by "email me a link" and then changes the associated email address for that account. How would the rightful user ever get access to the service again that was secured by "email a link" if there is no additional secret necessary for logging in and authorizing changes to the user data?
It all seems like a pretty bad case of shooting the messenger.
I am surprised that no one has yet mentioned the Gyrocompass: https://en.wikipedia.org/wiki/Gyrocompass

The post mentions manually-set directional gyroscopes, but gyrocompasses are a step ahead of that; on any sufficiently-quickly-rotating planet, a gyrocompass will point you towards the geographic poles by noting the axis of precession of a gyroscope with arbitrary orientation. That's even better than a magnetic compass on Earth, since the magnetic poles do not line up exactly with the geographic poles, and the magnetic is non-uniform anyway (which is why navigational charts include notations of the magnetic deviation in different areas).
Jasmine is widespread but Mocha is pretty much the norm for modules on NPM. This is in part because Mocha is considerably easier to instrument.
