As I understand it, Twitter is heavily invested in Java and the JVM. They maintain their own fork of the JVM that they tweak for low latency. As a starting point for speed and stability, the JVM is top of the line.

I like coding with Java 8. There's lots of new syntactic sugar that let you cut down on all the boilerplate and cool new standard library features like Java 8 streams that let you do functional programming. The best part of Java 8 streams is they perform really well. You get more readable code along with better performance.
No, I don't think that is assumed by most people getting married.
Great article! :D Truly praiseworthy!
You and your wife fell on the side of the bell curve where its two reasonable people who see their assets as joint. I guess both of you have high risk tolerance as well. Vast majority of people I personally know do not see their assets in the same way.

If you have illiquid assets, I think it is more important for you to have a prenup. Say if you have a one million dollar house and run a business that is also worth one million, you might want to give your spouse the house and keep the business for yourself in the prenup. After all, you do not want your spouse who knows nothing about your business to have 50% interest in it. And it saves the headache of having to sell the house and split the proceeds in a divorce.
> Uber and Airbnb

Imagine a world in which any object (human, animal, package, food) can be moved from one place in a city to any other place in the city using a smartphone. An electric, self-driving vehicle picks it up and drops it off.

That world is very nearly possible, and Uber is on the tip of the spear that's creating it. There's an absolutely massive upside. Uber is probably very under-valued.

Airbnb is less world-changing, but they still have the rest of the hospitality industry to replace. I personally never stay at hotels anymore, and I don't understand why anyone would. People will continue to use hotels less and Airbnb more.
There are very good reasons why Susan should be against a prenup. Suppose her and Daniel have a child, and they both agree that it makes sense for Susan to quit her job and raise the child at home.

If they have a prenup, a divorce is devastating to Susan. She's made no income and will likely have trouble finding employment since her skills may have atrophied. Does this seem fair?

Ask HN: What content recommendation services do you use?
I'm looking for a service that recommends me new articles to read every day. Ideally, it'd send me a daily email with a list of articles. It could be curated, either personally or algorithmically. Something similar to what Flipboard, BuzzSumo, and ContentGems(which was shutdown I believe)...

Go-lang is good but not as mature. Other than that, there's C++ and Erlang/Elixir. Not a whole lot of mature choices out there. For most of the critical production grade systems that need to be secure, have to scale and perform predictably, you don't want to blaze the trail.

The choice between NK/Iranian levels of isolation and complete free trade is a false choice. Plenty of countries have high tariffs for certain types of goods and do just fine. Even today.

More-over, I hardly think a tariff on the output of robotic labor applied only to expats who left the country for tax reasons is going to cause a trade war...
A perspective from Scandinavia; this sounds absurd and unequal. It's rare for anyone not to have a prenup here. The law also treats both genders equally in divorce (most recently, fathers' rights to their children were improved).

I don't really understand why anyone would even get married in California with laws like that, it sounds like a bad deal, for both you and the relationship.
Well, if I were thinking of my marriage as a business relationship it would have been an insane one.

As another anecdote, I have several LED bulbs from Philips (LPrize-PRO and Hue), GE (GE Link) and Ikea.

All of them are bright, work fine, and start instantly, but the Ikea drivers have a constant buzz. I've relegated those to bathroom fixtures that are only used briefly so that the sound won't drive me crazy.
I have the same confusion as the GP, so let me try to ask a clarifying question:

Is the challenge to partition the pairs (of natural numbers) such that both partitions are infinite and monochromatic? Is that the hard thing that was proved here?

If so, how about "color red if a = b-1, blue otherwise"? Then the infinite subset (0, 1), (1, 2), (2, 3), ... is monochromatic.

What criterion did my partition there fail to satisfy?
A prenup is a bad idea, because it means you're getting married.
I find it interesting that many of the comments seem to paint that marriage is about love/trust. This is a relatively modern interpretation of the institution. It has, since the dawn of time, been an institution meant to ensure stability and continual propagation of the species. It was usually a way to improve ones lot in life or ensure their well being. Also until very recently, last 150 years, it was common to have a marriage contract.

To me love has very little to do with marriage, those who seem to think that it does generally find themselves in divorce court. One should focus on having a shared vision of what they want their life to be and be willing to make room for their partners eccentricities. Emotions come and go and are not a great foundation for a relationship. Trust, compromise, hardwork, and support should be the bedrock.

Cards Aren't Cards
I'm always confused at how people pity those that work in menial, repetitive, uncreative manufacturing jobs (to give an example, see the flack that Amazon receives for the drudgery of its warehouse jobs) and at the same time worry about job loss from automation. These uncreative, "inhumane" jobs we have are precisely the low hanging fruit ripe for the picking by robots.

Of course, there is always friction in the redistribution process of the labor, but in the long run, I can't help but be optimistic about the increased human potential that can result from moving people away from menial tasks. Unless of course, you believe that some people are better off with tasks that require low creativity and human initiative.
A True Story (Almost) About Paul
Ask HN: Found a way to fraud my bank thru a loophole, how to disclose properly?
Hey guys,

First, excuse the messy title - I was limited to 80 characters.

I recently found a way to create money out of thin air through a loophole in my bank's current banking portal.
I tried reporting it a few times, but every time I am stonewalled by a low-level employee, telling me they will call me back later in the day, which never ends up happening.
The furthest I've come is to call their abuse department, found on their ARIN records, who seemed to take it seriously, but I ended up going full circle - back to the low level-guys.

I discovered it inadvertently and, technically, defrauded them of ~0.32 US$ using legitimate transactions that the bank's software should have handled differently. Pennies, but still.

I also confirmed the issue with other accounts and other transactions - my account is not a glitch in the system.

What is the best course of action? How would you get in touch with security officials at a big bank?

I mostly don't want to get caught or charged with (attempted?) fraud over $0.32.

I have also spent quite a few hours trying to disclose it, unsuccessfully. What would be the best way to get some of this time spent trying to do things right compensated?

Thanks!

I agree with your distinction between browser application and the web. Its very frustrating to be bombarded with tons of javascript that introduce nothing of value; usually advertisements and petty fanciness.

But that being said, ive been developing a heavy javascript SPA ( Single Page Application ) and have been writing javascript that is going to be very useful to (certain types of) users.

Im more than happy to download a large bundle of javascript (and css) if im getting an application (and preferably not on my phone)

And in defense of SPA's which dont even have web in them, good ones are a portal to a location on the web (a model type and id) loaded usually via json with html re-rendered on the client. And even better ones have history implemented. So they can feel very like the web...given js is enabled(!)

But of course I understand the "why reimplement what browsers already offer?" SPA's feel almost indistinguishable from a desktop app if done right...

What are your opinions on SPAs?
> Or we could hustle it out and have everyone desperately seek work to save their lives. Our choice. One leads to greater inequality.

This is a total non sequitur. Machines have been taking human jobs since the late 1800s and adding robots to take/process orders is no different. You discount the notion that new jobs will appear as "the free market argument," but new jobs will be created regardless of any tax on robot labor (negating the utility of such a tax) -- I suspect the driving factor here is the size of the unemployed workforce, not the need for money, ceteris paribus.

Moreover, the two problems you note (government and corporations influence on it) aren't policy or cultural problems (implementation details, if you will), they're problems with the fundamental nature of a powerful state and human society. Never has there existed a society where powerful institutions were not able to influence other, more powerful institutions (i.e. the state) with that said power, and as long as those institutions are run by men that cannot change. Individuals are generally corrupt (to some extent or another, if you give me $5 I'll shut up), and no amount of oversight or transparency will stop corruption so long as a critical amount of power supports that corruption. In simple terms, this is the tyranny of the majority, where "the majority" is measured in terms of power, not votes. This is the fundamental political dilemma, and limiting the scope of the state to only limiting the power of society's other powerful institutions is the only solution that solves this problem empirically, as opposed to the notion that corruption is ok as long as it promotes a certain set of ideals with which I agree.
This appears to be only for OS X. I use to be a big OS X user, but have come to find Linux is a far superior development platform for me.

From a comment on reddit: Most developers who use OSX do not develop for OSX/iPhone, but instead deploy 100% of their code to Linux VMs on EC2 or Digital Ocean. Their toolchain is usually 100% OSS terminal-based tools such as Vim/Emacs, tmux, clang/gcc, PHP/Python/Ruby, zsh/bash; all of which are available via Linux package managers (and have better support on Linux). While homebrew is nice, it's package selection is much smaller than APT/DNF/Pacman, and it's source-based so have fun waiting for LLVM to compile...

Eventually I realized I was basically a Linux user and I was trying to make OS X work like Linux. According to stack overflow dev surveys they show Linux experiences a 10-fold increase in usage amongst developers compared to it's typical rate of usage on the desktop. This also drew me toward Linux. OSX only experiences a two-fold increase in usage amongst developers and Windows actually experiences a large decrease in users compared to their desktop monopoly. Right now I'm developing React native applications completely in vim.

If this application ever comes out for Linux I'll definitely install it and give it a try. Only being on OS X makes it inaccessible for most developers.

HN has subpar URLs (in terms of UX), but they're still very useful. I can copy the bytes "https://news.ycombinator.com/item?id=11770774" and use them to get back to this comment thread later from any device with a web browser. I can give these bytes to a friend to refer them to this thread. I can share these bytes publicly and have a reasonable expectation that they'll allow anyone to retrieve the content on this page (not forever, but the Internet Archive and other caches have your back if this URL breaks in the future).
They also flash when connected to "glow in the dark" light switches, which was really annoying in my previous house.
The bottom line is that 2 people should educate themselves on the legalities of marriage before they enter into the agreement. Far too often people just jump into legal contracts without understanding what it means to them in the long term. The legal terms of marriage without a contract differ from state to stage and if the wife wants to punish you could always just move into a different state, reside there for the minimum time and then divorce you there to get the rules in her favor. Always try to see it from the good and evil side. The point is that you would not purchase a home or a car without a contract or knowing what the implied contract is before hand. I've personally been burned pretty badly in a past divorce solely because I didn't find out the laws before hand and was tricked into something that I was not educated on.

I've often been in meetings I wish I'd have recorded but didn't think about it until too late.

For that matter, I'd love the same concept with video, if there was a way to always record what I'm seeing without having to think about it in advance or wear a camera on my face, to capture anything interesting that happens to me, I'd be interested. I remember a story about an exec at Microsoft installing implants in his head for this purpose.

I'm terrified of anyone but me having access to this kind of data, though. It's nobody's business but mine.

Don't know about HeardApp, but I automatically assume the primary use case is for the company's benefit and not mine. Is it installing SilverPush on my phone and listening for things besides me to cross-reference and track my activity? I don't know...
I'm pretty sure similar numbers thought they needed a 'smarter phone' in early 2007.

This is why I don't understand why there is not greater support for national healthcare among the conservative / business community. Why do employers want to pay for that? If you decouple healthcare from employment, you encourage a lot more people to take risks and start new companies or simply try a different company.

Or maybe it is evil and employers know that healthcare is another way to keep their employees from bailing for another company.
