The purpose of being on the moon is having it as a massive manufacturing place for building things to move outward in the solar system. Lifting things out of the earth's gravity well is just too expensive.

The cost of shipping factories (and many raw materials) in pieces from the Earth to the Moon and then assembling them there should certainly outweigh just building and launching from Earth, especially as private companies perfect reusable rockets.

I do not see the challenges of building a habitat on the moon that much different from Mars. You have (essentially) zero atmosphere, lots of radiation, the same problems with building a pressure dome, etc.

Beyond just the gravity difference and the scarcity of any resources for in-situ utilization on the Moon, temperatures will vary from <-100 degrees at night to > 100 degrees (celcius) during the day. This is a vastly different regime than Mars, which has a much more temperate day-night gradient.

Landing men on Mars is certainly romantic, but it will be so expensive and time consuming that it cannot have much practical value.

It will be both expensive and time-consuming, but just imagine the science a few geologists could do on Mars, and what they will reveal about not just the red planet but also about our own.
- Looks like some guys are lowering the business end of a submersible trash pump into the conning tower. There's a flat hose attached, but it hasn't filled yet.

- Flat hose just became round, so they're pumping out the sub. All this is happening leisurely; looks like they're trying to do this with minimum damage.

- This is just some of the port crew and a crew from a heavy crane company preparing to move the thing. No emergency crews. They put the sub on a truck, using a huge dockside crane, and towed it away. Any investigation has already taken place or will be done elsewhere.
AIs would be better served by other sources of data - such as the game Dota2 - because they can get unlimited data to test out their strategies.

What AIs need is simulators - in other words - a world/an environment for them, where they can freely move about, interact and learn. The success of AI is linked to the development of realistic sims. Fortunately, the happiness of many people is also linked to the development of realistic sims (games). They go hand in hand.
the absence of the phenomenon is not more pronounced.
Not quite on the level of concentration camp liberation videos, but wasn't there a video of a 2 year old dancing that had like a 20 second clip of some popular song playing on the radio in very low quality in the background, and it got deleted for copyright infringement?

> adds a lot of difficulty and risk

That's a vast understatement. Don't forget expense and time! Orders of magnitude more.

I don't think there's any realistic way of getting a sustainable base on Mars without doing it first on the moon. On the moon you can learn from mistakes. On Mars you die from the first mistake.

Absolutely. Many of the comments here deride the default gdb interface but the TUI is orders of magnitude more usable and I only learned of it recently. (I much prefer it over Emacs' interface, for example, something another commenter recommended.) And in single-key mode it's even better.

It's really disappointing that something as simple as a string concatenation expression `a + ":" + b` has to be replaced with a pre-allocating monstrosity.

People look at price history of Bitcoin, see the hockey stick, and immediately call bubble. http://imgur.com/a/ifk2b

What they fail to realize is that these linear charts plot a $5 change the same distance when Bitcoin is $10 as when Bitcoin is $4000. Yet for Bitcoin to go up to $15 when it was $10 it had to increase in market cap by 50%. For bitcoin to go up from $4000 to $4005 it doesn't need jack squat, it's a rounding error.

A better view of Bitcoin's price is in log scale. Here you can see that the growth is steady: http://i.imgur.com/R9yQ8Dk.png

There is nothing special happening now, as there was nothing special when it went from $5->$10, $50->$100, $100->$200, $500->$1000, $1000->$2000. People just want them, and they are a finite resource.

I wish I could go to the studio/artist/creator directly and say "Hey, I would like to pirate your content, here's some money", but outside of Patreon or the like, there's usually not an option to do that.

Ask HN: Desire to be the dumbest guy in the room?
Hello HN,

I posted another thread a few days ago related to my possible job move from a startup where I had a very successful career to a Google-like company (it's one of the big 4), mostly because I'm bored in my current situation (https://news.ycombinator.com/item?id=14908269).

I realize the biggest cause of my boredom is that as a software engineer I'm not that capable and I am not improving in my current situation (I am comparing myself against some of my peers who work in other tech companies in SV). My "vast" success in the startup has been mostly due to most of our engineering team being outsourced towards cheap and junior talent in foreign countries (no prejudice! I immigrated in SV myself from another country, I'm just stating what my experience has been so far).

I realize that in order to improve I really need to be the dumbest guy in the room, which is very likely what I would experience at this "Google" environment.

Family and friends are telling me it doesn't really make sense, since I go from a startup where I have completely proven myself and am essentially free to do whatever I want (almost a "rest and vest" scenario) to a place where I would have to build my reputation from scratch, and even getting a lower title (I have a technical director-like role whereas "Google" is offering me a standard senior software engineer).

Do you have stories where a move such as this backfired on you?

Thanks!

Nice. So your primary goals and expectations are well balanced.

So giving you guys are doing this, you should maybe consider doing some exploratory goals, taking some different paths and decisions from the current browsers.

That may lead to some good innovations along the way.
Nice work. The drawing recognition feature seemed to work well. One little thing that could be improve is enforcing a minimum font size so that deeply nested fractions don't become unreadably small.
It doesn't. Especially considering all the other cryptocoin networks which facilitate the same service the bitcoin network does.

The very limited number of exchanges essentially have an oligopoly, and as price climbs slowly the fall in price and 'runs on the banks' can happen extremely rapidly as the exchanges have no obligation to buy your coins for anything other then 'market rate' which assumes there's a buyer.

Oh, and market demand is largely driven by bots and speculators - not the actual functionality of the BTC network.

Completely agree.

I actually have an offline repo with multithreading started but put on hold to focus on other issues. I'd like to implement threading sooner than later as it will be easier to do on a smaller project than a large one.

It's all about the architecture. We want to get that right first and are willing to throw away our current code to make sure we have this nailed. We are focusing on the renderer using a flow-programming style (only update what needs to change) as much as possible. So we're yielded to the OS unless there are pending events (using glfw). So no render() 60 times per second (unless there was something pumping events as such)

We're actually going to be converting HTML/CSS into JavaScript and the renderer will be handling a dynamic DOM. So we're not falling into trap of expecting things to be static. A couple of us are ex-game devs and have worked on HTML 5 games.

Thanks for the kind words.
While Bitcoin fans say it's both, their behavior is usually divided between using bitcoin as a form of value sink or value transfer. The former is good for an asset, the latter is good for a currency.

Right now, the volatile behavior of bitcoin shows it being much more of a speculative asset than a currency.
I'm still just trying to figure out what "Dota" stands for. Is it an acronym? Neither the Valve website or Wikipedia clarify this!
It's almost impossible given the Bitcoin network can only process 3 transactions per second.
Business valuations are different than currency exchange rates IMO. What's wrong with my comment? Is asking about something I don't understand wrong?
And what happens after the dips?
A fork has to be an idea about what Bitcoin is. This fork worked because some people saw Bitcoin as a settlement layer for a wider system of credits. Other people saw Bitcoin as a monolithic currency. The distance between those ideas caused the split.

Similarly ETH saw Ethereum as a beta prototype, and ETC saw it as a final contract. Those two ideas were each strong enough to support a community.

But this doesn't work arbitrarily. If I see Bitcoin as a currency primarily for selling ice cream cones and I fork IceCreamCoin, which responds to the seasonality of ice cream sales, there's no guarantee other people will see value in that idea, and mine blocks on my chain, or pay for coins transacted in those blocks on exchanges.

This is key to understanding cryptocurrency: there is no central reality. There are as many realities as you want. There are incentives to participate in some of them, but it's voluntary. You can walk away from whoever you want, and decide their money doesn't even exist for you, for any reason.
They didn't give free product coupons to customers. They paid contractors to secretly buy. With coupons, atleast customers can try it out and retailers are aware that free products were given out.

Realistically, Bitcoin is less than 10 years old and bubbles have lasted 10+ years before.

The real estate bubble, for instance, started around 1997 and didn't really complete its popping until 2012. That was 15 years and 10 of which people were 100% oblivious to it.

I'm not saying its nesc. the case in this instance but your "evidence" is no different than what people tried to argue to justify housing prices and such in the past.

Even with your log graph, there is a substantial disconnect from the trend line you drew vs. prices.
I already buy netflix and Spotify. There is zero chance I'll buy another service. If it's not in either of these and i absolutely must consume it (unlikely) then I'll get it somewhere for free. No way I'll buy another service. With av content netflix already offers more than i have time to watch. Music is different in that i still pass mixtapes (digital versions) around but there is little chance you'd find any of that content anywhere (except maybe soundcloud before it died)
This exists. On the Apple TV it's called the "TV" app. I'm sure other devices have something similar. On my Apple TV I see all the shows and movies I'm watching on HBO Now, Showtime, iTunes, and most other services in one spot. Netflix is the only holdout I've run into, and it pisses me off, but that's their prerogative I guess.

It's not likely to be an identifier. It's most likely a base64-encoded JSON, or some other similar encoding, followed by an HMAC. Probably the encoded data includes a nonce too, which is a largish random number.

Why write something to a database if you can stick it in the url instead? When you stick it in the url it lasts exactly as long as a user is interested in it. If you stick it in a database and give out an identifier you then have to expire it out of the database some time later. This either disappoints users because you expired it too soon, or costs you to store it for longer than it was needed. The HMAC ensures that they can ignore any data that was modified by a curious hacker.
Asteroids present other major difficulties, such as being much, much farther away, and having no gravity.

One thing I think a lot of people get wrong about tech is a "fear of large numbers". Our mind is trained to think linearly (ex. Path prediction when we're trying to get somewhere), and so when things don't align to it, it's very hard to comprehend. A friend gave a great example demonstrating this - would you bet that Uber/lyft will grow revenues by 25% next quarter or a boring newspaper company will grow by 3%. Doesnt the 3% seem like such a tempting answer, even though the former bet is most likely better?

I think something similar is happening when looking at cryptocurrencies (and several tech phenomenons). This fear of large growth numbers can inhibit clearer thinking (and you see that among public equity tech investors)

Fair enough. But I was just accepting the OP's conflation of DMCA takedowns and cease-and-desist orders. The concern remains valid in the latter case (I'm not sure the DMCA could even legitimately be used in this rather odd, inverted way, and agree that it's hard to imagine a valid use). My point is that nothing I do to a blacklist could "force" anyone to view my content---but I might have a legitimate interest in correcting a blacklist's mischaracterization or miscategorization of my content.
I don't see how you can compare Bitcoin to the housing market. The fundamentals are completely different.
I agree on all accounts, however, movies aren't really comparable to music. An episode of a show costs a ton more than a song to make (typically vs typically, there are cheap shows and expensive songs, sure). A movie costs a lot more than an album to produce. http://mentalfloss.com/article/57656/15-albums-cost-fortune-... has an album costing $15m to produce which was a huge outlier. Most expensive albums are in the $1-$2mm range. https://en.m.wikipedia.org/wiki/List_of_most_expensive_films has the most expensive films above $300mm a pop. That's two orders of magnitude, and granted there are way fewer movies than albums (I think), a Spotify for movies with tons of back catalogue coverage would probably need to cost $100-$1000/month to make it worth it to the studios.

Actually, $150 a month to legally watch almost anything ever made would be a fairly appealing option. Good luck getting even a few studios on board, though. Pricing in future expected rev into it, it'd probably need to be closer to the $1k/month mark to make it worth it. It'll never happen.
Twitter is more concerning, as it has connected society's social enforcers (those who are concerned with which views "have no place in our society") with media, government, employers, etc.

In terms of privacy, people have never been that concerned with "who's listening" so long as the scope of use is limited (eg, security cameras in carparks are seen as a sign of safety, not espionage, and people will happily mouth off loudly to their friends on balconies, untroubled by the ordinary passer by who might look on and scowl at the trash they might be talking).

It's not the overhearing and data collection part of zersetzung that's the most problematic -- it's the army of volunteers ready to take part in public denunciation and social undermining that people grow to fear.
Funny story. The original term "DOTA" was an acronym, for "Defense of the Ancients", which was the original Warcraft 3 mod of which the later game, "Dota 2", was based. Since the original DOTA was a community mod using assets from a commercial (IE, trademarked) Blizzard property, it was in sort of a gray area in regards to re-commercialization of what was essentially the same gameplay and characters. To avoid further standing for Blizzard to reclaim its trademarked properties, Valve registered the trademark "Dota" specifically as a word that doesn't refer to anything, officially eliminating the acronym from the name and somehow distancing the new engine from trouble with the trademark.
