My guess is that this is why they have so many problems. I'd guess that there's probably an accelerometer somewhere to give them an idea of what the swipe velocity is, so they can know how fast to play everything back.

But ultimately the way they've chosen to do this seems to be very difficult, especially if those are two very long single coils. It feels like it would be much easier from the software side if they had made them addressable somehow so that they could control every bit individually by either energizing or not energizing a particular coil. Then you'd have eliminated the swipe speed variable from the equation and a lot of complexity would drop right out.

Honestly looking at this teardown I'm surprised it works at all.
I have been trying to answer this question for myself, and one measure I've taken towards this goal is to record all of my mathematical reading, work, and random thoughts in a journal. I highly recommend the practice as it has been very illuminating to me since I started a few months ago. Reviewing my previous readings allows me to ascertain how much math I actually end up retaining from my study sessions, and keeping all of my work in one place (as opposed to throwaway scrap paper) allows me to spot any particularly common mistakes.

So far, I've found that my memory is far more tenuous than I had previously assumed. I'd look at last month's entries and realize that I'd only retained 20% of what I had learned; fine details being especially prone to slippage. Yet from analyzing my mistakes, I've also found that those very details are much more crucial than I had thought.

The result of all of this is that I've started to shift my focus from "learning new math rapidly" to "winning the uphill battle against memory loss." From this new perspective, the old adage: "the only way to learn mathematics is through doing" begins to make a lot more sense. While active learning is far from any cure to forgetfulness, given my own mnemonic capabilities I have come to see that it would probably be a better long-term investment to spend a month on fully working and understanding a chapter, than to spend the same time blazing through several chapters but skipping the exercises (having done both.)

I emphasize again that this is my own conclusion based on my own characteristics, and that is precisely why I recommend everyone to find their own answer to this question by keeping their own math notebook.
No federal court but pretty much every state court has.

The United States is one of few industrialized countries to have laws criminalizing adultery.
In the United States, laws vary from state to state.
Up until the mid 20th century most US states (especially Southern and Northeastern states) had laws against fornication, adultery or cohabitation.
These laws have gradually been abolished or struck down by courts as unconstitutional.

We spend far more time consuming content generated by our friends and family then we do consuming content created by media companies. I don't think he could conceive that a company like Facebook could control the means of distribution by providing something that people want more the professional media.
Odd. Here on Firefox/Linux using an underpowered laptop and 1080p monitor (indeed not the most optimal set up, but it's what I got right now), I expect most animations on modern websites to be janky.

But Sortable is completely smooth for me, yet Dragula lags or stutters a little.

I really wonder what the difference is?

I do have to say, even though they were slower, Dragula's drag-n-drop felt more "solid", in a way. Though I would guess that's some subtle clever placement tweaks, nothing that should affect performance.
trying too hard.

Just go to https://en.wikipedia.org/wiki/Bloom_filter

It's clearer and more informative.
Hacking Team was in the business of selling zero-days to government for the purpose of enabling surveillance. That's what people find objectionable.

It's the difference between culturing a microbe to make a vaccine or make a bioweapon. The latter should get your ass droned.
If I understand that scenario correctly, it assumes that there is a node that can successfully send messages to the other nodes in the cluster, but cannot receive any responses.

Since RethinkDB uses TCP connections, this shouldn't usually happen (since the TCP acknowledgements wouldn't get through either). The exception might be a layer 5 router / firewall somewhere in the network that allows the TCP connection to work, but only passes the data stream through in one direction.
RethinkDB is partially protected against this case, because we use bidirectional heartbeats on top of the same TCP connection that is used for Raft traffic. The heartbeat usually ensures that the other host is still alive and reachable. In this case, the node that cannot receive any responses from the remaining cluster would get a heartbeat timeout after a couple of seconds, and disconnect from the remaining servers. This is turn should limit further damage and allow the Raft cluster to proceed.

Please let me know if I'm missing something else.

Edit: There might still be some problems with non-transitive connectivity, where one node can talk to only parts of the cluster. We have built in some protection against this, but don't always handle that case well.

Uhhhh...no? I've lived in the US my entire life, and while I've seen pin and chip readers, I've never had a pin and chip card, never known anyone who has ever had one, and never seen one used. Ever.

Ahh, yes, your point is that the entirety of the command-line parameters may be under copyright, not just the alias.

The FSF would be against this view as it would imply that a GNU system needs permission from POSIX to implement "ls -l" or "cc -c", or if not something that simple, then a sufficiently complex/"creative" command-line API.

Therefore even if the court are undecided, the FSF is not going to make a copyright claim for linking the command 'gcc' to clang.

I know a lot of guys that love Resharper.. me, I always found it annoying and in my way.
Some people spend their entire careers working as pilots or flight attendants.
Life isn't like the movies.

Police should be masters at de-escalation. Instead, because they are not trained and motivated, they often create the situations which result in shootings. Not universally, but often. The people who shoot at the police _do_ have a reasonable belief that they'll be killed if they don't try to defend themselves. That is people who have committed crimes end up being more violent because they fear police brutality. Police in turn are quicker to turn to force in fear of their own safety.

This vicious should be and needs to be terminated by police learning how best to minimize the violent tendencies of petty criminals and the mentally ill. Don't get me wrong, the weapons they use are valuable and important tools, but they are so often used because the authority wants to use them.

I've known more than one person who before signing up, said openly that they were joining the armed services because they "wanted to shoot people". It's easy to find police on public media who clearly have the attitude that the people they work with on a daily basis are the enemy.

It's easy to look at the cops as the bad guys. "Fuck the police!" but that's falling for the same line of reasoning that the bad cops do.

You have to recognize that it's a systematic problem. The real world is complex – Americans really have to rid themselves of the Christian "good vs. evil" narrative we try to apply to every situation.

And it turns out that hostage situations in police shootings are indeed pretty damned rare.
Not really clickbait. Well kind of, but the article is fairly thorough at a high level.

"Pure energy" in this case is the bacteria are able to obtain electrons directly from their environment in order to power their internal chemistries that are needed for all cells to continue functioning. Those chemistries involve repair and reproduction mainly.

The key difference to all other known biology is that while all cells (singular or part of animals) use electrons for repair and reproduction they get from ATP.
The biggest issue that I had with ECS is that you need to initially create EC2 instances to put into your ECS cluster, using the AMI such that they have the ECS agent on them... BUT you have to prescale that cluster manually thereafter.

In the task definition - it would be MUCH better if you could select the EC2 instance type you want, collect them in an ASG and have the task slicing scale the ASG accordingly.

Right now - you have to manually determine the slice size for each container-to-EC2 and manually scale the ASG.

Further, it was noted that ECS is actually NOT AZ aware and it will spread load over EC2 instances in the pool -- but it wont also balance the tasks across AZs....

So, its a fantastic version one... but these are some resiliency and scaling features that should have already been included.
Haha! What is that supposed to mean? :D
Not sure how to answer that, but we're talking about maybe bouncing around Expedia, another portal, making a few queries on Trip Adviser, and checking the hotel website. Maybe 15-20 minutes tops? (I'm not talking about any deep bargain hunting.)

In some locations, I know where the deals probably are, whether because of company-negotiated rates or just past experience. But $50-$100 (or more)/night cheaper is not at all unusual compared to just choosing my default chain in a large city. (Though sometimes the price of the large chain is fine.)

And just last night I happened to get an email from a hotel I've stayed at previously in SF about a special. Turns out it was about $150/night cheaper than a rate I had locked in at another hotel just to make sure I had somewhere to stay for an event in late August. So I cancelled and switched. Took 5 minutes to save about $600.

My basic point is that, especially in expensive cities, there's a big difference between even doing just a quick search and just staying at the usual.
On top of all that it seems very likely that such licenses will be used to excuse what should be crimes against humanity, in the form of creating exploits and related software to enable hunting down dissidents.

The charges aren't nearly as bad on other carriers. BA and Lufthansa are probably the worst.

For instance, redeeming AA miles on Japan Airlines will generally cost <$100 in taxes even in first class for a US->Japan flight.

Then what's your solution? Telling everyone else they're wrong only goes so far — particularly in the face of the obvious and systemic problems that policing in America faces today.

So offer some alternatives instead of just knocking everyone else down.
Yeah, Elon sounded sad that they just needed to update the software to make it happen. They could have saved the Dragon with this adjustment.
Ask HN: How should I re-negotiate equity with my co-founder?
Started this project together, split the equity equally.

Idea was my co-founders', development work is mine. We still work great together, but he just can't put enough time on the project due to family, other work commitments etc., while my engagement continues to rise.

It's only been 3 months, but I would have worked 3x more and I'm full time on this now. I can clearly see that in future I would probably be handling 90% of the company work while he pitches in <10% of the time, as we keep on adding new features. The problem aggravates if we grow in numbers: it won't be fair to new people that someone who is working much lesser on the project has all the equity.

So this seems like a situation many would have been in. How do you suggest I handle this?
First, make the game. Then, make your game playable on a computer platform.

Do not make the technical decisions until you first understand the reasons why they need to be made.

Is the goal of this exercise to have a completed video game as the end result, or to have a child motivated to learn how to make such games? If the latter, it may be prudent to build up to the final product, by starting with "Hello World", implementing command-line interface "Tic-Tac-Toe" or "Hunt the Wumpus", moving on to a 2-D falling tetromino game, doing a simple 3-D demo, and so on.

But either way, the initial focus should be on making a fun game, and the details of the execution subordinate at all times to the question "Does this make it more fun to play?"
If it has a circuit to flow through, then how is it different from what's going on in a computer or in a brain?

A pure electric life form would be a bunch of electrons moving somehow in a vacuum. If it needs anything atom-based to exist it's not "pure".
Not nearly enough apparently

another huge problem is that buildings are being sold to international holding/investment firms at current market value, which will not allow them to keep the existing tenants at $1000 - $1500 per unit when the new mortgage for the new owners requires a minimum of 4k per unit per month.
Cool. That sounds sensible. Good luck! :-)
Try it, see what happens. And then write a Hacker News article about it.
The key difference between those technologies and this is that industrial production hardware (centrifuges or specialized biological equipment, etc) are needed in addition to specialized knowledge of the topic at hand. These additional requirements make export controls a lot more enforceable, and why you can, say, send regulators to the site of a nuclear engineering facility and get a reasonable answer about if they have sent nuclear materials to another country.

With infosec this would be basically impossible, since the specialized knowledge and the equipment are both non-physical and intimately entwined.

No, that's not true.

True (and, unlike the first sentence, a direct quote from Wikipedia) but also potentially misleading as to the trend with regard to adultery specifically by lumping together those three different things into a collective group.
I don't follow. The hobby is really only possible for Americans and American passports are easy to travel.

Actually, no. Airlines only release seats for award redemption if they don't believe they can sell them. Therefore, he's only taking up seats that would otherwise go empty on flights that are going to fly anyways.
Man, some journalists are so lost. It is so shameful that people have to report about things they know zip about. (in this case they are doing ok'ish).
I was living in my car for a month, seems like a short time, but 30 days seemed like years, so I know what intant pang of being unsure. I;m much better off now, but I think that feeling never actually goes away.

I actually create that feeling now by moving all but the bill paying funds to savings. Every 2 weeks it feels like I am broke. It gives me a sense of ownership and a feeling I am in control of the situation.
Hmm. Perhaps not... I hadn't heard of chip & signature until your comment. I set the pin online during card activation, and hadn't thought about it closely. So, it obviously must be chip & signature.

Anyway, that doesn't change that you can't clone the chip's contents. Perhaps you could punch the chip out (like a sim) and array a few of them inside a next-gen type of Coin card.

Chip & signature answers the "Amazon laughs at your chip&pin card" loophole I had been sort of half puzzling over.
> I don't think the break point is particularly unfair...

I wasn't saying it was unfair, just that characterizing $1 million in revenue as "huge" was, well, pretty ludicrous.
Maybe, maybe not -- I'd love to discuss it.

More importantly, I wanted to reframe your comment in a way that was productive. Instead of "Nobody has a right to private criminality.", it seems more conversational to say "Nobody has a right to private amorality."

Unity3D is great but it will likely be overwhelming for a 7 year old and for you as well given your background.
Bitcoins in Buenos Aires – Revolution at the Grassroots: Argentina
If a user has a sub-par experience browsing a website in one browser, she will switch to another and the loss is on the browser vendor’s behalf and not the website’s.

The vendor has an obligation to create the best web experience for the user and while it’s certainly a sad state of affairs that not more sites are testing for features rather than the UA string, it’s a sad fact that not all web authors care enough about interoperability to remedy their bad ways.
I came to an understanding of monads the other day thinking about fail-and-reverse-on-error applications like messing with the filesystem.

Allowing polygyny is not the opposite of criminalizing adultery; its quite orthogonal.

Its the opposite of criminalizing polygyny, which is also common in the US, but that's a different issue.
Yes, this is definitely a combination of learning, bonding, discerning interest level.

We've already began the planning and sketching stages, but we want to get our hands dirty soon.

No matter what the end result is, this will be a great learning experience.

No, exploits have the unique property that the "attack" and "defence" information are mirror images of one another.

Also, deployment of nuclear and bio weapons against civilians is against international law, whereas western governments seem to have chosen to deploy offensive hacking themselves rather than attempt to get it banned internationally.

Good to see another FT'er on HN. I've earned/burned about the same volume of points as you and can attest that this hobby is awesome, with some caveats.

For the beginners out there:

1. Be sure to read as much about earning miles as redeeming them. Both sides are equally important and redeeming is actually getting much more difficult.

2. Don't let the newbie blogs lure you into hitting credit cards too hard. Banks are starting to tighten the clamps on our hobby. Be sure to learn, start slow, and then start ramping up. Banks like to see a relationship, not just a high credit score.

3. If you're dipping your toe in Manufactured Spending (MS), start small then ramp up over time. Nothing worse than getting shut down for hitting something too hard. That said, MS is a great way to meet minimum spending without using too much money.

4. Don't let headline point valuations fool you into thinking you have to fly in Biz or First to get a good value on your points. Blogs use these kinds of numbers mostly to get you to sign up for CC's. Figure out your your strategy and go that way. A person looking for a lot of domestic flights is going to have a different strategy than someone looking to travel like saryant (and myself, incidentally).

tl;dr; This hobby is amazing if you can figure it out and do the leg work. I too enjoy good champagne 35k ft in the air ;)

If you have any questions, AMA! :)

Pedagogy? No, this article is written in that modern style of popular non-fiction which is meant to entertain above all other concerns, including such silly things as pedagogy, clarity, rigor, or sometimes even factual correctness.

This style is characterized by titles like "Catchy Phrase: The surprising tale of a subtitle that actually tells you what the book is about. Or does it?" "Catchy Phrase" tells the story of an single data point, or maybe three, with edge-of-your-seat tension provided by a jumbled chronology. It opens a generation before the main data point was born, then skips to the present day, before jumping into the middle of a tangential story. Then it's back to where we left the origin story of the data point, but this time we're in a different location looking at the second data point. Next comes some speculation about a possible rosy future and maybe a motivating example. Next we end the tangential story, which introduces the third data point, at it's funeral. The tangential story begins. As you read, you can see a complex theme slowly but deftly woven from the timelines of the several stories. It's a pattern that a knitter might call "felt". You can't help but be drawn in. It's so fascinating and intricate that you, like the author, sometimes have trouble distinguishing cause from effect, which adds an alluring air of mystery. The ideas must be Important. Despite the complexity, in the end the conclusions seem simple and obvious. You feel smart. You go to a dinner party and gush about it to your friends. They wake up the next day and, despite one-too-many cocktails, find that they remember the title of "Catchy Phrase". They look it up, and One-Click (tm) later, the life cycle is complete.

You aren't the audience, you're the vector.
