1. Both communities are big enough, if you are in Asia, gophers are everywhere

3. If you don't have any knowledge about functional programming, Scala will open you a new world. It will force you to think in a different way and will introduce you to many new concepts in how to solve parallelism and asynchronous computation using easy concepts like immutability or far more complex like functional reactive programming or duality.

2. I worked with both languages, I liked the fact I was able to write a whole, easy, REST web app in just half a day with Go, but the syntax and the verbosity in error handling, made me kind of crazy. I would definitely say that is a very good language, extremely fast compared to others like Ruby or Python and it can be even a very good complement to Scala.

Scala is my favorite language, by far, for server side projects. It requires time to be mastered, there's never a "Scala way" or a single way to solve a problem, but there's (almost) always a best solution. Twitter's scala school[1], for example, is a good place to see examples about when and how to use certain language features. The fact that runs in the JVM, a Virtual Machine with 20 years of development, improvements and optimizations, is almost a killer reason to pick Scala. I worked with Java/Spring/Hibernate in the past, a very frustrating experience, but Scala changed my mind about the JVM and opened a completely new world: Functional Programming. Now I know and use concepts like Monoids, Monads, Future/Promises, Reactive Programming, Actor Model, Duality, etc... without any problem. It's a complete different world and I think it deserves a shot.

> if you are looking at many such landings it becomes worth doing it 'once' and properly.

Yup; the point is, SpaceX is not trying to just recover the first stage, they're trying to solve the vertical-landing of rockets for rapid reusability - which is vital not only for cost reduction, but for their plans to go to Mars. Because if they solve landing here, they can use the very same technique to land on Moon, Mars and other planets.
How so? I'm glad to trade 15% of my pay check in order to work 15% less hours. As a salaried employee I wouldn't have had the option.

<zaroth>: I'm not sure why you were downvoted, so have an upvote.

Not saying I entirely agree with you -- calling it a "tax" is incendiary and no more accurate than saying "why do we need to pay a 10% tax to grocery stores or Amazon?" -- but your broader point is an interesting one.

I'm pessimistic about this application of p2p discovery in the short term, but in the longer term (>7 years) you may well be right. The short/medium-term problem, and this goes back to 1990s discussions among cypherpunks about anonymous reputation systems, is that those "honest reviews" are attractive targets for gaming.
Because they're drugs. Someone just picked a different name for them so that daily use sounded more socially acceptable.
So the time that is involved in this algorithm is some rough constant K * length of list * time taken to sort the average word on the list.

If we were likely to see variants of the problem that scaled up both in the length of the list and the length of the words in the list, then we would properly describe the performance of the algorithm as O(n * m * log(m)), where n is the length of the list and m is the length of the longest word in the list.

If, on the other hand, we assume that m is bounded and will never exceed a relatively short length (for example: because these are english words, not arbitrary character strings), then we can say that m*log(m) is essentially a constant, and the performance of the entire algorithm will vary meaningfully only based on the length of the list.

That seems a reasonable assumption, so we say the performance of the algorithm is O(n).

This is really interesting. I haven't tried it, but it's definitely a new approach to designing WordPress themes (as far as I know).

When most of the industry hires based on the social proof of the candidate having been being hired by other companies, and doesn't have any interest whatsoever in investing in training, you have a feedback system which would amplify even small biases - if the biases were small, which they're not. If you start out any kind of poor, you are statistically fucked. You have a brutally vicious survival function which shuts people out starting before their first possible job, and then continues to shut them out - it's only so many applications you can file before you have to fall back to landscaping or catering or spring for a degree in accounting or some other industry that is not buried so far up its own ass (does every employer who needs an accountant demand a top 1% A player 10x accountant, or do they just hire a fucking licensed accountant sometimes?)

Where are the _____ engineers? As a rule, they're in the huge fucking pile of resumes in the garbage. But that answer is too simple and obvious, it makes the situation too clear. Instead, it has to be a big mystery about how it just magically happens that there isn't a black face in the office even though we are all, of course, very enlightened and not racist here on HN, and all of us are doing our very best, so sorry if you don't have enough experience for any job or are not a cultural fit anywhere.

I really do like the presentation and the whole site. I just couldn't resist the comic book guy opportunity.
The point of the "don't use a framework, make your own" is that your needs are different enough from everyone else's needs that it's worth writing code just for your needs. The problem with releasing a framework is that your needs are different enough from everyone else's that it's not worth releasing that code.

Personally I'm glad that T3 released their framework - it doesn't harm me, after all, and they did all the work - but I think some people have unrealistic expectations on the value of code re-use. The problem is the economic incentives in the software market: chances are, if your problem is close enough to somebody else's problem that you can re-use the bulk of their UI code, your market is too undifferentiated for you to exist as a separate company. When frameworks do attain market success (eg. JQuery in 2006, when IE6 was the dominant browser, Firefox & Safari were brand new, and Chrome didn't exist), it's usually because the big company in charge of the overall platform has been asleep at the wheel, and then the need for a framework disappears once they get their act together and start moving the platform forward (eg. JQuery in 2014).

It burns three times after the second stage detaches. The first is to get the landing zone closer to the takeoff, the second slows it down from 1300 m/s to about 250 m/s, the third slows it to (hopefully) 0 m/s on the landing pad. Here's a diagram: http://media2.s-nbcnews.com/i/newscms/2014_51/812491/141217-...

If the 'x-wings' are what I think you're referring to, they're the landing legs. They are shaped like that to have as minimal impact on the air resistance of the ascending rocket as is possible. They open just before landing.

It can't hover. Even just using a single one of the nine engines, the engine can't be throttled down enough for the rocket to hover. The landing method relies on what they call a 'hover-slam', where they fire the engine during landing to slow it down just before it touches.

Landing this is extremely impressive. It is going four times faster than the speed of sound, and they are landing it on a pad smaller than a football field. Vertical landing of a returning rocket has never been done. It's also the key step in the process of dramatically lowering the cost of spaceflight which could usher in a new era of technology around earth, and on other planets.
Yep, it's almost empty. It shows how much stored energy rockets deal with and how hard it is to get out of this gravity well we call home.

Yes, very nice, helpful site.

.format() is mostly too verbose for my tastes. Even Guido himself put it into the "meh" category in a talk. To be clear, I do use it when I need quick lightweight templating, say building a very complicated string.

But for most simple output printf style is shorter, simpler and I know it by heart. There was a guy at work who insisted on using .format() for everything that soured me on it, sometimes even simple string concatenation:

print 'result: {long_var_name}'.format({long_var_name=long_var_name})

Sometimes lines reached 200 chars. If lines were broken down, they might extend to 4 lines for each debug statement, adding tons of clutter. Said it was more readable because you could ignore the end. :/

As sago said, printf is more concise in the majority of use cases. Not to mention the logging niceties:

log.info('result: %s %s', one, two) # shorter and note that fmt is deferred!

A _big_ one in my eyes. Too bad logging doesn't support {} internally.

I've also wondered if .format could be improved if the % operator could be used with it, given appropriate precedence rules. Or perhaps use another char... dunno & or /?

print 'results: {} {}' % results
print 'results: {} {}' %% results
print 'results: {} {}' / results

Pycon, are you listening? ;)

From a desktop perspective, yes, but Linux at this point has a majority stake in pretty much every other realm of computing.
Makes me wonder if they just leave them on the ground of the ocean or recover them?

Well, that's not always true (thinking of the numerous times I have had to optimize code written by people with this attitude), but I wasn't speaking about performance. Macros allow you to do things in e.g. C which cannot be done via any other mechanism in the language.
Facebook and mobile-phone companies in India got together to try a project.

The project aimed to provide cheap internet access... only to their "approved" websites. Anything else requires more money from the customer... Or perhaps money from the companies whose websites are blocked.

People are starting to realize/acknowledge that the arrangement is a bit of an anti-competitive conflict of interest with a tinge of "pay us or we'll block you" extortion.
Yep. They're doing it at sea because they're in the late alpha stage of this reusable program.
I agree, it's not a problem in most spaces.

I'm one of those not so lucky souls that could benefit from having the GIL removed. I do a load of concurrent read only access from multiple threads of execution on a large object in memory. At the moment I'm forced to fork using multiprocessing. It works, but it sucks to have the overhead.

Though, as you say, it's really a non-issue for most workloads.
This how NASA recovered the SRBs. They landed upright, much like SpaceX's rocket. They were bouyant and floated vertically. The tender would approach the SRB, hook onto it, pump more water into it so it would sink. It would then carry it horizontally back to land.

Seawater is incredibly corrosive and as it evaporates it leaves behind a fine layer of sea salt. Since these were SRBs, they had few moving parts. They were completely disassembled and the individual components were inspected and recertified prior to the next launch.

Also, just to give you some scale of how crazy the Space Shuttle program was: the SRBs are the largest lift platform that was ever in use. ICBMs are fireworks compared to them. To land in the water, the SRBs needed not one but 3 of the largest parachutes ever produced.
The RCS thrusters are powered by compressed nitrogen, not the rocket fuel that powers the main engines.
Interesting.

From site: "3GW Regional Energy Storage Hubs. Energy capacity may range from 4 to 16 hours duration at full power output."

The 3GW is big but the duration is small, so I'd guess they're doing short term grid stabilization, competing more with flywheels than hydro. That's just a hunch, but if that were true, it'd explain how you could get something really effective without a lake-sized train. (Some videos online suggest they move a bunch of heavy cars on the same track independently, so they probably also get much more weight than a normal train.)

My limited understanding of pumped hydro specifically was that it really was basically just a turbine operating in two directions, crazy as that sounds. Even so though, I can easily imagine big cost savings just from not having to engineer around water. That stuff doesn't compress, you design or run these wrong and they'll just mercilessly explode:
https://www.youtube.com/watch?v=6hVUeNp3o3M

Being able to build anywhere is really neat too.

So, grid storage tends to fracture into a half dozen specific types of storage, all based on duration, spin up time, geography, fuel, etc. There are like 18 different tradeoffs, and you can specialize in any one of them. Pretty much any new grid storage technology is going to add to the field rather than displacing anything, because the grid needs arbitrage in basically all 18 different dimensions.

Thanks for the link. There are some cool ARES videos on youtube too.

Well that's why pretty much every psychoactive drug has a warning for people with mental "illness" like that. Stimulants apparently can contribute to psychosis. OTOH, I've known people that get prescribed amphetamines like mad because they're too tired out from all the anti-psychotics and mood-stabilizers. Seems a bit counterproductive.

Mania can be happy. Or at least a terrible funfuck of a ride while it lasts. At least for the person experiencing it. If they don't have to deal with all the consequences.
Yes on so many occasions. I want an Angular or Backbone FE coupled with MySQL/Apache or the complement of the MEAN stack for the BE.
Why would successful developers and publishers integrate Hoomi?

Is user demand for Hoomi their only incentive? Or is there a positive benefit for them as well?

If the former, it's not clear why developers would rush to support it until it accumulates a very large and uncompromising user base; and building that user base will be hard without a lot of apps/sites already integrating it.

Another sub-species is the organization that does nothing but get inactive VCs/Angels to small events and charge founders $20-$50 to attend and $100-$500 for 'a table' for the company Names like Lifograph (aka Cofounder Club) or FundingPost come to mind- They seem not to do anything except these crappy events constantly with the same 6-7 tired VCs year-round. Great way to charge for tickets, for 'tables' for companies to display, and sponsor fees.
The fine amounts being thrown around are mostly bad journalism. The law allows a fine of up to 10% of annual turnover, but even in most hard-core cartel cases, they will not go into the upper bound.

Other fun placebo effects: red pills work better than blue pills. All pills work better if given to you by a doctor. Better still if the doctor is wearing a white coat. Yet better is the doctor uses a large peace of medical machinery as part of the intervention. And yet a bit better on top if the machine beeps.

It's interesting to think that if you are building rockets, up til now you've never really gotten to take the rocket apart _after_ flying it - it's burnt up in the atmosphere or at the bottom of the ocean somewhere. I imagine there will be lots of interesting insights that come out of recovering, undamaged, a flown first stage and taking it apart to see what's experienced wear etc.
This further illustrates how terribly unfair modern medical systems are. Want to change your brain chemistry? You've gotta do a song-and-dance for a doctor. Who might either hate "addicts", or be terrified of the DEA. Do a poor job lying and try again? Oh, now you're "doctor shopping", which some want to criminalize. Have an in with a doctor or have enough money, well then it's no problem. (Sure, money buys a lot of leeway in everything, but this is a fairly basic freedom.)

I'm not an American but from what I was taught about folks like Ben Franklin, I think they'd be shocked to know it has become illegal to determine your own treatment.

It must be amazing working in a field where failure is almost as exciting as success.

What's the main obstacle to slowing down and stabilizing the rocket on its descent to the platform? Is it just a matter of speed or also the shape of the rocket and its center of gravity? Would a set of 3 parachutes might slow it down a little bit or at the very least straighten it before the rockets need to kick in saving some fuel?
Luckily this doesn't appear to compete with React. This seems to be focused on composing a large-scale application from many different component applications. It's the kind of thing you have to do at large companies that have many different groups and are bad at communicating and collaborating on a single code base. React helps you simplify your view logic. The two should work together quite nicely.

Just yesterday we had a meeting with the team at my company that's responsible for building the glue to allow our flagship product (~$4b profit per year) to be composed by independent releases created by independent teams that aren't always communicating on a regular basis. They built a library based on the whitepaper that was published by the main developer behind T3. At the time they started, there was nothing publicly available that served the need. But now, a company following in our footsteps will have T3 and won't have to waste the time that we did building it.
