brad@sendwithus here. It's amazing how often we get asked by other YC founders what lifecycle emails to send and when to send them.

We've (somewhat accidentally) become quite knowledgeable on the subject. Super stoked that we're able to share this information with everyone trying to start a company.

>Game Maker and Unity are trying to make the full stack as easy and accessible as possible.

That's pretty much my point.

What people need is a full stack to solve their problem, but they need the stack to be able to be customized to their particular variant of the problem.

That full stack will have a lot of code that is beyond 95% of people's ability to create. But even though Unity uses C#, artists and designers I know who are absolutely not programmers (by their own insistence!) can and do successfully create games on top of Unity.

And that is the future of making programming more accessible. Not creating a better language, which is what the original manifesto was about.

Excellent explanation. Thank you! If academics want their work to be used, writing with the utmost clarity is necessary.
I came here to point out this exact same thing. Why use vans and trucks to re-balance stations when you can have people re-balance them?

Not only can you can have dynamic pricing based upon stations and times, imagine having a feature where you can "call" for a bike at an empty station. There can be an app that notifies people near other close non-empty stations to ride a bike over for you. Or, you could even display it on the screen of the kiosk.

How would you get people to ride these bikes for re-balancing or on demand?

Offer something like a rewards plan (re-balance a bike X number of times and receive a discount on your next bike rental) or pay them in micro-payments (Think Tom Hanks returning luggage trolleys in The Terminal).

How could you ensure that people riding bikes on demand don't take advantage of the process to just get a free ride to wherever?

First, make sure that the bike being taken out is checked into the station it's being delivered to. Second, impose some sort of time limit in which that needs to be done. Base the time limit on an acceptable pace and take into account the distance between the stations (with a time buffer). If it exceeds that limit, it becomes a regular rental and the deliverer is charged regularly. Also, it then becomes possible to add bonus incentives for getting the bike to the station faster.

One particular bonus of this system is that it can leverage a city's homeless population as a workforce. (If you disagree due to cleanliness issues, I'm sorry to tell you that the homeless already use citibikes as cycling machines). Of course, there would be a need to hedge against the possibility they may just take out a bike and never return it, since they don't really have any sort of credit. One possibility would be to sponsor a homeless person by covering the cost of a bike and then having them operate on a "one strike" policy.
> How? Space is not like driving a car.

Isn't it? You drive, you burn fuel. You take more fuel with you, it costs more fuel to get going. Some vehicles (spacecraft or car) require more fuel to drive the same distance than others.

Sure, space flights are much, much more expensive, but I don't see how it's so different. If it's not worth it to spend the extra fuel to get there, refuel, and continue to the original destination, then just say so.

The quote from George Lucas, speaking before congress on the importance of preserving films in their original form when the phenomenon of colorization was kicking into high gear, was a treat. The discussion in the embedded video of the technical challenges amateurs face when doing their restorations is interesting.
How is equity granted in a way that favors employers? I'm curious what you mean.

The caveat I'd add to your first point is... bonuses for me have been an important part of accelerating savings and retirement. I personally do not define my financial success by my month-to-month standard of living but rather by my net worth. And in those terms, a bonus dollars spends the same.

Of course, though, that in the hypothetical case you were offered $10,000 raise or $10,000 bonus, certainly the raise is better. But that's a strawman. A more interesting analysis would be where is the line drawn? Is a 5k raise better than a 10k bonus? I'd probably take the bonus in that case, honestly, because time value of money and all. So where is the line drawn?
We use it for push in production, and it has worked very well (we haven't had a single issue with it thusfar). Haven't used any other parts of it.
Since I cannot edit this post anymore I'll comment on myself: I really do appreciate the downvotes, but could anyone comment why? Because I may be unknowledgable about space flight, but I'm not trying to troll or anything.
IME, many big companies are so change-averse that an event like this is mostly irrelevant to their projects. Even if the external developer who was previously maintaining the library were still maintaining it, the project the big company is shipping would still be like 2-3 major versions behind with no immediate plans to upgrade.

Having access to the source and the legal ability to modify it without releasing rights to their own IP is the only issue I've really seen big companies be wary about when it comes to using external libraries, and practically speaking that's probably all they should be worried about.
It's a nicely done site. It may just be my interest has diverged from generic tech news, but this looks like internet scale bikeshedding. It's not the biggest impact developments, or the biggest breakthroughs, it's the boring stuff that's relatable to a large number of people so it gets a lot of low quality comments.
Yes, but if there were no more miners, you could process all transactions on a single cheap laptop, which probably costs less than $1/day to run.

It really depends on the company and market location you're in. Around here (SF / Silicon Valley), there are tons of companies hiring Ruby devs. So if you're around here, that's probably the route to go.

If you are interested in Enterprise, Java is probably still dominant.

JavaScript is a must for front end stuff but I can't say that a lot of companies will adopt it heavily for backend, particularly if most are already established on some stack they've already been working on.

My best recommendation without knowing much is go with Ruby and Rails.
Proton aside, Soyuz is singly the most reliable launch vehicle on the market, since the retirement of the US Shuttle and ULA Delta II. It has both the longest track record of anything out there, if you look at the entire R7 family, of over 3500 flights. It also has a success rate of over 98% over the past thirty years. The Delta II reached a similar ratio, but over only 140 flights. Also, the Soyuz is one of only three vehicles that Arianspace is able to launch from French Guiana.

Edit: I should probably note, Delta II isn't completely retired yet. So the two are sorta kinda still tied. I've been a Delta II fan for a while, but they're down to selling off stockpiled hardware. Prices kinda went through the roof with the GPS contract going to EELVs. It's a shame, since it's the end of a fairly good track record. But we still have Soyuz.
I was the person that initiated using the closure library for a team back in 2010. It took ages to release products using it, someone called it the "write more, do less" library and I have regretted the decision ever since, especially when Google came out with Angular which felt like a total slap in the face. Closure Library had half hearted support, and even teams inside Google hated it, which is why Angular probably came about. It felt like a slap because people that bet on Google supporting Closure couldn't just stop using it and start using Angular.
Does anyone know of a general & special relativity simulator? That is, a program where I can setup various "thought experiments", by placing clocks and masses at various point in space, where they can have various acceleration profiles, and can communicate with each other, and run the scenarios? I never really understood the twins "paradox" and the explanations for the source of the asymmetry seemed hand-wavy and "because".
Endogenous factors are addressed in the paper. Nothing personal, but I'm getting so tired of people on HN saying 'well, maybe they made an elementary statistical mistake...' They're professional statisticans working with a large and robust dataset,a nd they devoted 6-7 pages of the paper to discussing how they controlled for such factors. And they brought up your exact point in the very first paragraph of that discussion:

[...] In particular, while the effect on well-being has been largely explored in the case of face-to-face interactions, we do not have conclusive evidence about the endogenous relationship between online interactions and well-being. This weakness suggests caution about the generality of the results provided by previous literature. Individual effects such as personal characteristics may be correlated with both participation in SNSs and well-being. Happier people may also be more outgoing and open-minded, and may have a higher propensity for various kinds of social interaction. [...]

It's fine to be skeptical, but couldn't you at least do the authors the courtesy of looking at their methods and pointing out where you think they fall short?
Options vest monthly. RSUs often vest quarterly. Very different IMO from a yearly lump sum, and sort of blunts your and GGP's argument here.
There are two problems with setting goals for anything but menial tasks:

1) It's incredibly hard to set goals for complex projects without having unforeseen problems or side-effects (e.g. the product shipped on time, but it's buggy)

2) Experiments have consistently shown that creativity is negatively impacted by incentives (possibly due to stress causing narrowed focus)
I feel that blocking Russia from SWIFT would be quite ballsy on the part of the EU, but ultimately Russia and its partners won't need SWIFT. With the development of the BRICS Bank [1], this eventuality is inevitable. Does it happen now, with some pain, or later is the question. But Putin is really testing the resolve of the West. Personally, if China and Russia develop serious business dealings we'll all be in for trouble, as it'll pull China into any conflict, and quite frankly all China wants to do is business while autocratically ruling its (large) corner of the globe. The gambit now is weighing the possibility of strong economic ties between China and Russia, and the longevity of Putin's leadership.

Overall, this conflict in Ukraine is really bad news. MH15 was only the tip of the iceberg. I personally feel it should be handled firmly and swiftly, before it escalates any further, because, quite frankly, what amount of territory is "enough" for Russia/the separatists.

Why is zokier's comment meaningless? The article talks about the cost in bitcoin. S/he's talking about the effect on the environment, which is another legitimate concern.

It looks like the 18 animals were actually sub-divided into at least three test groups. One test group got the drug after 3 days after exposure, one at 4 days and one at 5 days. So the number of animals in each sub-group is closer to the control.

It wouldn't surprise me if there were actually six test groups of three animals each (perhaps divided by both day-of-treatment and something else like drug amount), thus matching the control. But the article doesn't actually imply that.

This is my summary based on skimming the article:

The authors find that social network usage has a negative correlation with happiness.

To control for unhappy people turning to social networks (reverse causality), the use instrumental variables (IV). This involves finding an instrument, that is something that causes people to use social networks more/less in a quasi-random way. Their instrument is availability of DSL. I'm not sure how they deal with DSL availability also affecting happiness through other mechanisms (e.g. general internet usage). In any case, the correlation between social network usage and happiness is not significant once they use the IV strategy.

They then use a method I'm not familiar with (structural equation modelling, SEM) to obtain some other results which are discussed in the abstract.

I believe that the abstract (and the popular article discussing it) should have mentioned the insignificance of the correlation when using the IV strategy, since I doubt many casual readers would by able to critically evaluate the SEM strategy (which yielded the results that the abstract and journalistic article discussed).

It has always seemed to me that "I love that I get paid to do what I'm passionate about!" is in most (clearly not all) instances either a form of sweet lemon rationalization or else a kind of expression of stockholm syndrome.

That I am passionate about something does not imply I ought to be compensated less for it than I otherwise might be and, no, providing a space merely for me to do what I like is not "compensation." Employers love that there are so many people for whom "money is a poor motivator." It assists them in keeping the imbalance that exists stable (or growing).

Also, that paradox really only applies broadly to a very special kind of person, and generally only to people who are in professions for which a substantial minimum income is the general rule. I also suspect it's only true for a certain range (e.g. an additional 5-15% might not be of interest, but start talking about 20% or more of an increase and that gets to be another discussion altogether).
I'm more familiar with companies that have vesting schedules like: 10% per year for 3 years, then 70% in the final year. That's a great way to keep someone around for an extra couple years who doesn't want to be there.

I agree with you that your example is a lot more similar to an $n/4 raise. It's kind of like a "resolution" of your pay. Ideally you get paid every day for the work you did that day. $N/4 reduces the resolution to every quarter. My example above reduces the resolution to every 4 years. Each one increases the length of time you're going to keep someone working for you that otherwise wouldn't be.

As another reply mentioned, this can be a good thing. Keep around a talented person who you really need. My bet is that more often you're keeping around a talented person who isn't giving >100% (a passionate person will), and is probably poisonous to team morale too.

At first I was surprised, it looked like Zynga was doing something nice for a change. In the end, it seems all they're sharing is the bad news.
Since when were bonuses measures of merit or performance? It's more likely they're measures of company financial performance (in the case of the net pool), and the political whims of a manager (in the case of individual distributions).
I also worked at WF and in my area (mutual funds) front-end was weak as hell. There were java developers, designers who still thought in points and "pixel perfect", and marketers, and just about nobody in-between. Granted this was a few years ago, but not long enough to excuse the ignorance. I can't speak too much about the rest of the company other than as a customer, and based on my experience as a customer, the front-end is weak as hell for everything else too.

No doubt people get "money back". Contrast this however with a system where "numbers" (= the new "Randomcurrency") were randomly, or evenly distributed among the general population, which could be done basically for free.

Compared to that, there is a cost, if you will. n powerplants had to be built, or x tons coal had to be burnt to do all the calculations. Does that make sense?
It can also mean they're working closely with a small number of customers to rapidly prototype and validate early versions of a product.
Long vesting periods, and the fact that, well, what you get at the end is an investment in your employer. So it's like getting money, except you don't get it for a few years, and someone else invests it for you.

As far as 10k bonus vs. 5k raise, sure: if you're being offered 10k now versus 5k over the next year, and you expect to receive another 10k next year in lieu of the same 5k, then you're coming out ahead. But the case I'm talking about is when you're getting a compensation offer including a bonus, in which case you're choosing between 5k over the next year versus 10k in a year (maybe).

A signing bonus of some sort, where you're receiving an immediate guaranteed payoff (or even a guaranteed payoff at some point in the future), is a completely different beast than a performance bonus as part of a compensation package.
I agree that we should always at least read the linked article (and sometimes the original paper) before bringing out "correlation does not equal causation".

However, you are overstating the case for the author's having dealt with reverse causality. From the conclusion:

When we addressed causality in IV estimates, the significance of the correlation between participation in social networking sites and subjective well-being disappeared.

See my top level comment for my own take on the article.

Exactly. If this were implemented, it would affect me one of two ways*

1) The cost variation would be small enough that I'd ignore it.

2) The cost would sometimes be high enough to dissuade me from taking a bike where I wanted to go, in which case I would quit the program completely. I don't want to have to change my travel plans at the last minute.
Even if the extra cost were non-trivial but acceptable, the mental overhead of having to decide whether it's worth it would make the program much less appealing.

* If I were actually participating in a bike share program. Currently I own my own bike, but I could see using a bike share program in the future.

Please look at the test script again. It does indeed warm up the JIT.

The timing results come from within HHVM. Basically, the test is dispatched within HHVM, isolating just the function call itself. It's then executed 5 times (timed independently) and then the bottom 2 executions are thrown away. See: https://gist.github.com/ircmaxell/8859d7f1bbee7b2f6e16#file-...

So the warm-up period happens. It's not just "benchmark `hhvm file.php`". The benchmark happens inside of HHVM.

So yes, JIT warmup is accounted for 100%. In fact, PHP, HHVM and Recki-CT all execute with the exact same pre-compile steps (parsing and any pre-compiling are ignored in the benchmark).

And their AOT approach that they tried was all-or-nothing. Meaning the entire code base had to be converted. This is a "compile what you want, and run the rest normally". In fact, this is 100% compatible with Hack and HHVM...
