Why not just save a bunch of time and use new boosters? Then reuse those boosters for other missions? Reusing rockets is great for saving money, but that doesn't mean you need to reuse the same rocket for this one mission; if you have a business going with, say, 30 missions over the next year, you're probably going to need a lot more than one booster in stock anyway. Or, instead of new boosters, use a bunch of reused boosters for the Mars mission, letting other commercial customer who insist on brand-new boosters help subsidize your Mars mission.
I'm so glad you noticed this - it was bugging me.

I've noticed a pattern in "X vs. Y" articles where the examples of the technology the author doesn't favor are unnecessarily complex.

The point about feeling drained when the startup is failing, and feeling energized when you hit something people wants is spot on. My startup failed (as most do) and since it happened I've felt that I was not made for business. But recently I watched how my brother hit a strike with his company (still small but people is super interested) and I see how that keeps you much more energized.
Maybe I'll try again soon, but this time I'm starting really small till it takes traction on it's own(another usual tip I didn' listened the first time...)
I wonder if recent UI enhancements really improve the discussion, or if they are just indicators that we've reached that critical threshold.

I don't remember wanting for collapsable threads and such four or five years ago, but now I can't imagine sifting through all the junk without them.
Well done commercial for Cloudflare.
It's bubble gum pop, the sort of thing that is immensely popular across all media, but not the best, and easy to sneer at. Quite different from "awful", which would be something like Eragon.
any post-intermediate (or advanced) js courses ?
The PDF manual sold by FreeRTOS, "Using the FreeRTOS Real Time Kernel - A Practical Guide", is worthwhile. I agree that the web documentation is somewhat lacking and suspect that for better or worse, it is that way in order to encourage buying the book.
I agree that it's harder to solve a problem that you're not experiencing, but, by the same token, underserved communities will tolerate an even lower threshold of quality as long as you're helping them :)

For the approach on how to solve their problems, the main goal is empathy.

Look at the Design Thinking theory: first step is to emphatize.

When I was taking a marketing course, they told us to shadow a consumer. You have to "walk a mile in their shoes" For example, I've been very impressed by the use of artificial impairments to simulate the experience of people with real disabilities.

Once you -really- understand their problems, I'm pretty sure any sharp mind here will come up with interesting solutions.

Look for the Bootcamp material too:

HOW to empathize
To empathize, you:
- Observe. View users and their behavior in the context of their lives. As much as possible
do observations in relevant contexts in addition to interviews. Some of the most powerful
realizations come from noticing a disconnect between what someone says and what he does.
Others come from a work-around someone has created which may be very surprising to you as
the designer, but she may not even think to mention in conversation.

- Engage. Sometimes we call this technique ‘interviewing’ but it should really feel more like
a conversation. Prepare some questions you’d like to ask, but expect to let the conversation
deviate from them. Keep the conversation only loosely bounded. Elicit stories from the
people you talk to, and always ask “Why?” to uncover deeper meaning. Engagement can come
through both short ‘intercept’ encounters and longer scheduled conversations.

- Watch and Listen. Certainly you can, and should, combine observation and engagement.
Ask someone to show you how they complete a task. Have them physically go through the
steps, and talk you through why they are doing what they do. Ask them to vocalize what’s
going through their mind as they perform a task or interact with an object. Have a conversation
in the context of someone’s home or workplace – so many stories are embodied in artifacts.
Use the environment to prompt deeper questions.
What's wrong with light-hearted easy reading for adults?
Exactly. Flow even has tagged unions now, and `maybe` types. TypeScript is also a very mature solution to this problem. A true professional works with whatever language he needs to solve his/her problem, and shores up that language with the best tools available.

In this case, I half agree, because I think mobile development is best done using native platforms. But if you're doing web development, JavaScript is a must. And React is an elegant way to handle browser UI (Flow/Redux is also quite nice way to handle browser state, if a bit verbose).

I do share his concerns about the patent clause, and about Facebook's long-term commitment to the project, but at the level of personal projects, these concerns have not been enough to scare me away.
Note that they were using titanium, and while I'm not sure what the fuel cells were made of, until they heated up it leaked quite a bit. One of the first orders of business after takeoff was getting a refuel, which included changing the type of fuel, see e.g. http://iliketowastemytime.com/facts-you-didnt-know-about-sr7...
Datacenters still a year away from adoption of direct-current power distribution
That doesn't make sense to me. If they are understaffed and underfunded then you would expect the number of granted patents to decrease.
The SpaceXes of the age of colonization, such as the East India Company, used to sell shares to fund their voyages. I was a bit surprised not to hear Musk mention this as a funding option, since he just delivered the greatest Kickstarter pitch of all time...
Yes.

Tier 1: Those who solely re-implement. You can do a lot copying and pasting. It's just not worth as much money.
Tier 2: Those who re-implement while creating anew, typically in specialized areas or occasionally very well over a wide range of tasks.

Note the importance of re-implementation to both job tiers.
1. You have a good point that "certain mechanisms" are relevant; I spoke too sloppily. Stating the goal without taking any action pursuant to the goal is, as far as I know, fine.

2. You are incorrect on the law to say "whether or not they have that purpose"; race discrimination in admissions is legal (for public schools) when performed for an academic purpose such as "to increase classroom diversity", and illegal when performed to "correct for the effects of structural racism". This is the root cause of the talismanic promotion of "diversity" today. The school's stated purpose is relevant to whether their action is legal or illegal. (If you think this is a travesty, I couldn't agree more. It's still the law.)

2b. Interestingly, some methods of race discrimination (speaking generally, the objective ones) have been found to be illegal regardless of stated purpose. That's a separate issue.
> Were you a foolish humanities student when you got your bachelors?

Yes :\

Yes :(

This is a much better perspective than my usual one. Thanks!
How Elon Musk Plans to Go to Mars
I don't think that person's first language is American-English, which might be why her word choices don't sound like normal American-English.
Hey if you pay for the research and development, equipment, transportation, construction, and deal with the myriad of other problems that come with living on another planet I'm sure you'd be free to make your own rules. You make it sound like Elon owes us something already.
you have to remember that a lot of gain come from economy of scale, making bigger planes, the gains are realized only if passenger traffic increase (hence total pollution).
Google is not going to abandon cloud. I'm not sure anything I say can convince you, but the fact the Spotify, Evernote, Disney, Home Depot, Snapchat, etc all run on GCP says a lot.
Musk got in the position to do what he's doing by figuring out a new way to pay for stuff.
No reason I can think of why you can't drop empty batteries in an emergency situation. In fact, you probably want swapable batteries to begin with, don't want to waste time on the tarmac charging up.
this is so important! Our retros are just engineers & engineering-adjacent people (data, design, product managers). My boss sometimes comes to the meeting, his boss doesn't. I think our vp also comes sometimes, but he was one of the first engineers and is always open to feedback, so it's not like "the boss is in the room, we have to be on our best behavior"
> I'm sure someone has tried over the years out of a scientific interest.

Maybe as a hobby idea. But has anyone seriously tried, with an 8-9 figure budget, a team of engineers, etc.? Shipping in supplies is cheap. There is little financial motive to make a self-sustaining colony.
I thought it's the opposite: banks want to stop paying fees to trusted third parties who run central settlement databases.
I'm all for colonizing Mars, but is it possible to do large-scale terraforming of the surface without a magnetosphere to protect it?
Yep. This. I know it's not cool to point this out and that front-end folks upgrade Node all the time, but installing Node on a "normal" machine inside your average IT environment is a complete pain, whereas you can do pip install azure-cli as a regular user without installing anything else on most Linux distros out of the box.

Also, I've had nothing but trouble with recent Node versions (and I'm a pyenv/rbenv/*env/etc. guy, have multiple runtimes of everything around, etc. - but most people would try once and never try again).
They actually learned a bunch of things from that. Including that the concrete took CO2 from the atmosphere in chemical processes that was unexpected, leaving the plants short and not producing enough oxygen.

The insects and plants selected didn't cohabit well, as well another issues. There was clearly lots to learn from the experiment.
>> but by the same token, invited entire (and continuing) mountains of half-assed, unsupported(unsupportable) code that just begets generations of garbage.

Pournelle's Iron Law of Bureaucracy. One reason to favor startups even if they so often suck in so many other ways.
Here is a thoughtful essay that deals with some of the potential issues: https://quadrant.org.au/magazine/2015/05/eugenics-ready/

He makes a distinction between "negative" eugenics (removing genetic disorders & decreasing mutational load) and "positive" eugenics (selecting for intelligence, appearance, personality, and other desired traits), and considers what will happen if either of those is adopted by either a minority or a majority of the populace.

At a high level, the biggest concern is if you have a minority of the population practicing positive eugenics, because it leads to a runaway "rich get richer" situation. If you think income inequality is bad now - it will only get worse.
agreed. just use it raw. Or with mapbox
Note I am not the original commenter and am rudely butting in, because internet:

1) "To each their own" doesn't work when we're talking about politicians, because only one of them gets to be elected leader. Arguing might make you uncomfortable, but you have to do it.

2) It's possible to be unimpressed by all current candidates, and to believe that our current political process does not filter for good leadership qualities.

3) I'm actually impressed by Pope Francis, despite - or perhaps because of - the distaste I hold for Catholicism and organised religion in general. There's a man who has colored strictly within the lines as far as his job description is concerned, yet has done a great deal to lead by example and improve the moral stature of his office.
Everything you need to know about SpaceX’s plan to colonize Mars
Are you certain of that? It's mentioned in a few places (including Wikipedia), but I've not seen any SpaceX sources saying this was a sub-scale test article. On the contrary, we've heard Elon say that because of the very high chamber pressure, you can get the thrust they're looking for out of an engine about the size of a Merlin. And while it's hard to be 100% sure, from the pictures I've seen the unit tested at the weekend looks kind-of Merlin sized. Not conclusive, of course, but likewise I've not yet seen any hard evidence to support the idea that it is sub-scale.

Are there any learning opportunities that you can ask for at work? New technologies you can explore while improving the company in a small way? If you're not excited about the technologies you're currently working in you can find ways to grow. It's kind of up to you to ask for them, though.
His plans are unprecedented and complex and investors are notoriously short sighted. If he IPO'd, people would be demanding instant profits even though SpaceX is operating under a different kind of timeline.
The alternatives mentioned here are not really of the same type. A better example of an alternative would be something like https://www.nativescript.org/
The ideas are a bit too long for a post here on HN, but if people are serious about wanting to pursue a startup in this area then get in contact with me [1].

I know there are lots of people wanting to start a startup who feel they don’t have any good ideas so if this is an area you are passionate about then I am happy to talk. I am in the lucky position of having the financial resources to fund a new startup, but because I am busy running my own business, I just don't have the time to do it myself. When I was younger I had lots of time and no money, now I am older I have the lots of money and no time :(

1. I am pretty easy to find and do a background check on.
This is less of a pedantic point than might be assumed.

The Gaussian depends upon a notion of independence and identical distribution: independence can be dispensed of when one thinks about power laws.

If you can soberly state the assumption that the effects of a comment on any other comment is completely negligible, or falls into a couple of other strange exceptions that leads to the universal phenomena that generates the Gaussian, then and only then can you state that any quantity associated with comments is Gaussian. I do not think that this can be soberly stated as such.
I really don't care about this. My entire point is that taking off your shoes at a home's entrance does nothing to prevent the need to clean the floor. Dust, food crumbs, and shed hair accumulate regardless.
motivation:

- Dependency management for Node.js adds maintenance costs for Linux distributions.

- Cloud tooling vendors prefer Python to match AWS CLI and GCloud CLI.

- Python offers a more mature platform for building CLIs
Python is typically available on Linux distributions by default.

- While none of these reasons precluded building the next CLI in Node.js, Python was the natural choice.

They're great fun, but not great literature. Big explosions, chases, larger-than-life characters with interesting quirks but little nuance (although he gets better), edge-of-your-seat world-in-peril type stuff. I know plenty of people who love them, including myself.

They suffer fairly badly from Lensman Arms Race, so by about two-thirds of the way through the series Dresden and his friends are now so ridiculously powerful that you can tell Butcher's having a hard time coming up with decent a threats for them to vanquish in the each book.

Basically: above average pulp urban fantasy.

Edit: There's a TV series, fairly loosely based on the first few books. I rather liked it. I know plenty of people who didn't.

I'd say with GCP, the managed services are key. Pub/Sub, Global Load Balancing, Firebase, BigQuery, Container Engine, etc. They just work, no need to mess with things. Price to Performance and simplicity is also good, but that's secondary IMO. I'm obviously biased, but hey!

With AWS, the ecosystem is massive. They also have the most features (though GCP and Azure have their own unique features and are catching up fast).

I haven't used Azure, can't really comment on it.
I evaluated React Native for a project and decided to go with NativeScript instead for a number of reasons:

1. RN releases a new version every 2 weeks breaking my app every time. NS is a lot more conservative between releases.

2. I don't like mixing presentation and logic, RN encourages doing so, NS does not.

3. TypeScript is a first-class citizen in the NS environment, it is not in RN.

4. Angular 2 > React

5. NS created a smaller executable with better performance than RN for my test app.

6. I couldn't get RN to work with one of my older devices (KitKat), and even though dozens of developers had already reported the issue, they don't care. NS worked in the same device just fine.

7. All the tooling around the RN ecosystem is very confusing.

We all know the type (and if you don't, hang out in rural America more).

This is a human universal, not in all people, of course, but the urge to destroy for some sort of twisted pleasure is hardly limited to the domain of shooting in rural areas (and, heck, there's way too much unjustified shooting of people in urban areas), it just takes different forms elsewhere.

Ever see someone kill their own company, or division of it, just out of some similar sort of bloody mindedness and urge to destroy (even if they also have an urge to create)? Or regress to childhood, there are those who love to build sand castles, and those to love to destroy the sandcastles of others.
Sam operates YC, which is a company. If the argument is that he lacks operational experience, and YC is a company, you've defeated your own argument.
Bad code? Yes!

But C++, Java, Perl, even Python has a bit of a learning curve that demands some small amount of commitment (and more importantly, understanding) to get moving with.

Javascript, VB, PHP can get a person creating things in an afternoon (which I am not against, I like that it might inspire people to get into "real" development), which invites hit-and-run development.
> As a VC or researcher or whatever, you're not actually playing the game. You're not on the team, you're not on the field, you're not even on the side-lines. You're seeing a different game than's being played.

I think it's actually the opposite: if there's a good founder/investor relationship, the investor is an extended part of the team, is sometimes on the field (helping close job candidates or doing customer intros), and is often trying to help from the side-lines. Not all founder/investor relationships are this good, but some are.

To use your analogy, the founders are football players, and investors are somewhere between "football fan" and "football coach", but probably a lot closer to coach than fan. It's true that neither coaches nor fans are actually on the field playing the game, but coaches have way more insider info. For example, they watch players practice and have a deeper understanding of what each player can and cannot do, they know which players might be nursing injuries, how to motivate different types of players, etc. That doesn't mean a great coach could be a great quarterback, but I think lots of players would agree that a great coach knows a lot about how to become a better football player despite not being a football player themselves. (And to extend the analogy, I think coaches are good at helping players improve despite the fact that some players might lie or make excuses or paint rosy pictures or whatever.)

Allow me this thought experiment: One person holds up a black box and asks you to stick your hand inside promising up and down that it is not full of venomous snakes, another person does the same with a transparent box.

Yes, but there is more than enough effort/energy/enthusiasm available to do both things. Both things are valuable and we need them both. And we can afford them. What Musk presented costs about as much as an Olympic game.
The biggest similarity I see is given away by the Methane/Oxygen engine. This means he's aiming at generating fuel on Mars.

The biggest difference is the emphasis on reusable craft.

we also do individual team retros as part of sprint planning, which are just teams. (lead, engineers, product manager)

Stuff that comes up in these can get promoted to the all-engineering retro. If it's a controversial topic, discussing it in a small group is super helpful because 1, you can clarify your thinking before bringing it up in front of 30 people and 2, your team has your back and can support you if it becomes a heated discussion.
You do realize that Python was not only built to appeal to "non-devs" as well ad devs but, does, in fact, enjoy some of its strongest support from them- scientists, engineers, statisticians, etc., who do not consider themselves to be good developers. And, man, they can develop some crappy code/systems in Python too.

I like Python too (as well as node,) but your characterization of node is over-broad and, imo, inaccurate.
He briefly mentioned about creating artificial magnetic poles to shield the Mars city from radiation. No details though. Maybe we could have learned about it the Q&A session was a little better.
