One solution is to collect a payment when you buy a new gadget, then you get it back when you return it for recycling.

At the moment recycling technology can already grind stuff into small particles and float it in salts of different densities to separate it. That doesn't go to atomic level of course...

I think it's a fundamental outcome of the laws of entropy that separating always takes a lot more energy than mixing, so if you've mixed it, you've lost the game already.

You can't have "lifetime" that means there's an interest in someone dying. Much better to just have a fixed time period.
This should be no news to consumers who have been accustomed to parking their money in negative bonds. These are called "checking and savings accounts", where interest is next to nonexistent, and the balance is nibbled away by various fees.

People still put their money in the bank for similar reasons why people buy these negative interest bonds: for example, it's secure, and cheaper than building your own safe, putting cash in it, and guarding it.

If you want to hold some foreign currency, you could just buy it and have it sitting in a trading account. But there are perhaps some fees involved which are worse than parking it in a negative bond. The account may also not be secured compared to a bond.

> I tried to use j2objc and I thought it was the biggest POS.

GWT was also an idea whose time had not yet come. I'm sure that the success of InBox makes the developers forget some of the blood, sweat and tears it probably took to toolsmith a cross-platform architecture. But they took a conservative approach, sticking to networking, sync, and local persistence. They picked parts of the app that would be using similar-enough APIs on all platforms that the abstractions don't get out of hand, and the learning curve for maintainers isn't too steep.

If I was looking at a big-enough project to justify the toolsmithing, I would be looking at how they did this.

> . Some of the problems we end up working on are extremely difficult, yet because we are idealists, we go around telling everybody that everybody can do it, probably out of sheer enthusiasm for the things we do, because we believe the world would be better and maybe because we want to share with others our passion.

This right here is the money quote. This is why I am very wary of taking a position as a "developer" or "programmer", and not a consultant. Computer science is one of the most intellectually demanding professions in existence, yet a bunch of kids who are talented try to stunt and make it sound easy. It's like the world's greatest Neurosurgeon posting his surgeries on youtube and saying "anyone can learn, come to my bootcamp!".

Absolute nonsense. It probably has to do with them trying to signal competence for mate selection...If that's the case, I've got news for you boys, CS is never gonna get you laid. Money on the other hand, most definitely will. So focus on your boatloads of cash, not how "easy" CS or programming is, and leave the dignity of your profession untarnished.

> I wonder what happened behind the scenes that basically killed Ubuntu in its tracks.

Ubuntu has never been profitable for Canonical. Shuttleworth's game-plan was always long-term minded regarding Ubuntu -- but as we've seen as-of-late, Canonical is shifting focus to other markets they view as potentially profitable. Shuttleworth has committed to keeping Ubuntu alive, but it's no longer Canonical's sole hope for income.

> I don't see why they could not get support contracts with Dell, HP, etc to sell Ubuntu computers and provide the tech support in exchange for positive cash flows.

This isn't just a problem for Ubuntu, but for most end-user linux distros. People always joke with Linus when the "year of the Linux desktop" will finally arrive... The people who use Linux as their daily driver generally don't need the support, and for the ones who do, well it's a lot less marketshare than Windows.

> Even today Dell is still doing Sputnik

Besides Sputnik, and some Linux-only end-user manufacturers like System76, there really isn't a lot of choice for pre-installed Linux end-user computers.

It's weird too, because Sputnik is $50 more expensive than the windows version of the same hardware. (probably some Microsoft deal going on here).

Linux comes pre-installed on majority of server hardware (server hardware than comes with any OS at all that is), and Linux dominates this field. But the "year of the linux desktop" hasn't quite arrived yet. I do hope it comes soon.

Nothing really to be honest.The reason is because no one really trades domains.
Ok, so my question was, why you need objects at all if you're deciding that your objects should be immutable, and if I'm understanding you correctly, your response is essentially that you need objects if you want inheritance.

Because the extensible open recursion you're talking about only matters in a situation where you're working with base classes and subclasses having different implementations of the same method name and needing dynamic dispatch to determine which one gets called at runtime.

Clojure's hierarchical multimethod system is an interesting alternative approach to this that I think fulfills the semantics you're talking about. I guess you could argue that this is a sort of immutable object system, it's just not called that. http://clojure.org/runtime_polymorphism
Aside from a host of fixes/refactorings, the biggest change is that it now supports WebSockets, with either a WebSocket origin server or HTTP origin server.

Also, the backend protocol (GRIP) was refined to work via HTTP headers instead of JSON instructions in the response body. This change helps simplify backend code and makes it more readable. The response body mechanism is still supported though, since it's more extensible and may be needed in rare cases (such as status code 304 with Apache).
You might be right, but I don't know if that counts as black swan. Greece and euro troubles were mainstream headlines five years ago spring of 2010. Through out the years the situation has been evolving and nobody of course knows how it will unravel. I'm more surprised how slow the buildup is.
Did you even read the article?

Sounds like you accept the fact that the Subaru can die at any time. The article specifically talks about how that's a privilege that many people don't have. If someone is living paycheck to paycheck, and could get fired from their mcjob for being late, then having a car die could literally lead to homelessness.
What sort of machinery did farmers use "back then." (not sure how old you are)

I ask, because some of these mega-tractors have a lot of functionality (more complexity seems to just cause more points of failure), but you can still buy a good old general purpose tractor that will last a lot longer.

The Facebook Page That Posts the Same Picture Every Day
Could you point me to any source where it is calculated? This seems especially suspicious, since high speed growth started only 200 years ago (in 18th century the average per capita growth in Europe was 0.1%), in 19th century the average growth was about 1%, and in 20th it reached 1.9%. This gives around 20-fold growth, which is hardly similar to 400-fold one.

The oft-touted claim is that client-side templating is easier, but they're the same, really. The server solution is literally using the same exact templating engine and code.

What people are conflating is "doing things in the client with JavaScript" and "rendering templates in JavaScript", which are two entirely different domains.

You can't access many cool features client-side without JavaScript, full stop. But rendering things on the client, and presenting an absolutely un-usable design without turning-completeness is not content-first design.
I've thought about improving my resume but I've had an excellent web agency respond positively to it (and say they liked me after the interview – no position for me right now though). So far I've taken this as a sign that my resume is good and so I'm afraid that making something trendier or more creative (mine's rather classic) might make myself look desperate/fake? On internships: I'm currently looking for one.
That second comment nails it. Family farms are going the way of the dinosaur, and large outfits want a machine they can use for three seasons, depreciate and eliminate for both a tax write-off and upgrade.

I legitimately believe we'll see the death of true family farms in my lifetime (I'm in my 30's). What we'll see are family farms in name only, with a multi-million dollar, multi-national backend.
I've yet to finish my way through. But it is amazingly precise and thorough. There are a few mistakes that the reader catches easily if they've been paying attention.

Ask HN: Who Should We Hire Next?
Hi HN,

Myself an a mate started a small software agency 2 years ago (http://inoutput.io), and have been lucky enough to land some big clients (public transport/insurance/trading industries) building bespoke biz automation apps. We work on nerdy things: Big-data, desktop apps, system integrations.

Things are going really well, hired 2 more devs in our first year - and already feeling like we need to hire again.

My co-founder and I both love programming - and although I have done ok so far - neither of us wants to spend 100% our time scoping, writing giant docs, client management/comms, etc.

My question is, who do you think we should hire next (or rather, what "role")?

Another dev would probably mean I have to take the project manager role full time (or close too),
and I don't really have experience with hiring a Project manager (or B.A) that is that technical to be able to fill that role... but I guess they must exist!

Is there such a thing as a magical developer that doesn't want to develop, but instead wants to do technical scoping, write documents and talk to clients? ;)
Looks like they killed 3DES, leaving only RC4.
Last year when I was looking for internships I interviewed with Khan Academy. They pay about as much as Google does (for dev interns, anyway).
How does this compare to http://canistream.it? Does it offer any different functionality?

How are your search results generated? I searched for "Witch Hunter Robin" and got 30 results, none of which were that show (and many of which don't even seem to be related to the search query, such as "Red: Werewolf Hunter"). For comparison, canistream.it gave me a single result for that query, which was the show I wanted. Granted, the show isn't available on any streaming provider (canistream.it says it's available on Cable Xfinity only). Do you only provide matches for shows that are actually available somewhere?

Also, curiously, your site lists "Good Will Hunting" under the title "Will Hunting".

Edit: The site does appear to be quite fast, which is nice. And you have a mobile-optimized version, which is great as I nearly always perform these kinds of searches on my iPhone.
why not both !
Let me play devil's advocate here and suggest a few reasons why bypassing this "minor hydraulic sensor" might not be the smartest move.

1) Someone might get hurt.

2) Some really expensive part of the machine might get damaged.

It is within the realm of possibility that the engineers who designed this system knew what they were doing when they decided to shut down an entire machine when a single "minor hydraulic sensor" goes bad.

this is exactly why I, as an employer, would be curious to see if you had done any side projects. it shows you have a track record of going out on your own, building something, and getting stuff done. which is an amazing trait in any potential employee, especially at a startup.

so I don't see a way to "get around" it. How about some project from school?

You don't understand. The web is content-based. Like motherfuckingwebsite.com [0] shows, you don't need dynamic content to present your message. If I need to download 1MB of JS to see your freaking tagline, then that's ridiculous.

It's not just for users on slow internet or older devices- Bustle was a good example, because as a content site, it generally has a lot of assets to load.

Fastboot can get you over the hump of the initial load when you're linked to a content-heavy page on the site for the first time, and hide the download/boot of the JS app for the moment it becomes ready.

> And she noticed an interesting pattern, those children usually come from families of engineers, mathematicians or software developers.

This is a serious issue, there was an article on HN a few years back on how the concentration of children born with Autism in SV is something like 10x higher than elsewhere across the nation. They concluded that its most likely due to a severe case of assortive mating between mathematically gifted couples.

People wanted to know why evolution didn't continue to make us smarter? There's your answer...there's an upper ceiling imposed by biology. The way our neural architecture develops puts a damper on how much abstract reasoning we can do before we sacrifice our basic survival mechanisms (i.e. social interaction).

Autism is one of the most fascinating conditions from a medical perspective, but its absolutely terrifying when the majority of HN (myself included) is at greater risk of producing autistic children.

That is the great thing about that old equipment, especially the really mass-produced models. Everything is mechanical, and most of it is built out of heavy duty steel, so between wire, duct tape, a stick welder, and a hammer, you can fix 90% of breakages. If something goes that isn't that easy, there are after-market manufacturers, or you can take something that isn't quite the right part and modify it to work, or find a salvage job on craigslist to scrounge from pretty easily.

Yes, though the overhead of requiring annual extensions might be a bit much.

Input LaTeX, Tex, AMSmath or ASCIIMath notation to make formula instantly
Yeah, well, my parents grew up on farms and starting in 3rd grade our property was sort of one, it came with a hand crank starter. And "my" vehicle until I left for college was a 1967 Jeep, and all this was in a farming region to which I've also retired to. Where I now help my father repair his eminently repairable Grasshopper mowers. So I kinda expect farmers to do some of the basics about this sort of thing.

Going to the text I was working off:

"It takes a technician at least two days to order the part, get out to the farm, and swap out the sensor."

"Order the part" sure doesn't sound like a same day thing. Maybe this only shaves off one day on average. But I can't see how it doesn't shave off some time.

I grant you your last point; if this isn't a single lemon(ny) part prone to failure he's getting unacceptable service. And I predict this gambit will not end well for John Deere.
Well, by the white-hat route, you would talk to a farmer for a long time, figure out the exact dimensions of the black box, and build a white box to replace it.

By the grey-hat route, you analyze the black box and patch out or bypass the security features in it. You allow the owner to jailbreak the hardware, while still largely using the original manufacturer software and firmware.

By the black-hat route, you illegally access manufacturer proprietary information and publish it, possibly along with statements indicating the exact extent to which the company profits by arbitrarily limiting the self-repair abilities of its customers. This would make it easier for the grey-hats to write jailbreak exploits and discourage farmers from buying in to the abusive business practices.

If you ever want to be paid for it, white-hat is the way to go. You have to look at how farmers currently use the technology and then figure out how to replicate those use cases without the use of closed technologies. Think about how Tomato or OpenWRT help people use their wireless routers in the way they desire. You would essentially be writing new firmware for a piece of hardware, albeit hardware that can cost the owner tens of thousands of dollars if used incorrectly.

Without knowing anything about tractors, I would guess that the modern ones include a digital hardware controller that can monitor and control every aspect of a diesel cycle engine. They may include GPS receivers and mapping and routing software. They would also include modules to control the interchangeable tools that may be mounted on the tractor, which would require sensor feedback.

By this time, they should be largely self-driving, and maybe even have their own Twitter accounts. I'd save that crap for last.
