To be fair, Warren Buffet has never been much of a traditional entrepreneur but I would certainly listen if he gave me advice on my business.

Perhaps some people are players, some are coaches.
A scale model of the engine. It's not full-size yet.
This seems unfairly negative. It may strictly be true that his ventures are "still in the early stages with uncertain futures." But the ambition and degree of difficulty of those ventures is also relevant. If you look at Tesla and SpaceX, I'd say the degree of success so far, relative to the degree of difficulty, is quite remarkable.
I still think it's many, many orders of magnitude easier to survive on a messed up earth than on a fresh Mars or Venus.

Extremely interesting.

Please tell us more about the LTE capabilities. Is it provided by a removable board? Which bands are supported??

Based on https://www.dragonbox.de/en/45-pyra it only supports B17 and AWS, which makes it mostly a AT&T compatible device

I wish it would support other bands, B25 for sprint (which has cheaper LTE plans)

Also, the wifi chipset is known. Can you run a hostapd?
Fees, dude, fees!

(More directly, it's not easy to sell nor charge a lot of money for just a database, so this is a genuine advance in sales technique.)
> What about going to a different planet makes you think we won't just be taking those same problems with us?

It'll just be wealthy people for a long time. Wealth is strongly correlated with intelligence, peace, and other desirable factors. Perhaps the social baseline will be a lot higher. This is hard to predict given that we don't really know what the psychological and epigenetic effects of going to mars will be.
Heavily disagree. I still use RSS constantly. Sure, I don't think RSS will be here 100 years from now, it'll die someday, but I've yet to see an actual alternative to it.

This is a nit pick, but isn't his "Ambiguous curly braces" example actually breaking due to automatic semicolon insertion?

Isn't valid anyways. ESLint easily flags it as an error.
People don't consider that not only does the software engineering process weed out those that don't know algorithms, it also weeds out those that don't have the discipline to sit down and study for a couple of weeks.

Thank you , but what I meant was in heavy work load. I know the basic ideas. But I am curious in heavy work load which one is preferred for what. AFAIK Spotify went with GCP, many big companies went with azure, most startups chose AWS.

What was the reason behind these, personal preference? Or technical superiority?

The reason for my curiosity is Microsoft and Oracle kind of sees Cloud Computing as life and death situation.

But I agree, it is a not a very explanitory theory since it is too black-box.

I think hackaday is a good example of a community with similar (techie) people to HN that has gone further down the same path of negativity, cynicism, and salt. HN is great and the moderators here do a good job (I'm always impressed by the way dang handles issues), but I do think some sort of push is needed to get us off of that path.
Here's one example, and references to several others: https://en.wikipedia.org/wiki/Biosphere_2

Bloody typical of the US. They get permission for a climate monitoring station and construct a military base instead, leaving tons of toxic waste behind with no thought for the people who live there. I hope Greenland is able to secure from the US government all the hundreds of millions of dollars necessary to clean up their mess.
Yeah, that aspect was cringeworthy.

Lesson learned: if you're running a big event with Q&A, always always either restrict it to qualified people or vet the questions before they're asked.

Don't allow a general audience to just form a line in front of a microphone.

If you're an organizer hosting Elon Musk, the heads of the major national space agencies, and the leadership of all major aerospace companies, you don't want to give some assclown 60 seconds of microphone time to ask whether there will be enough Portapotties on Mars.

Thought experiment: I'm sure that this video will get over 1m views on Youtube. 1m * 60s = about two years of people's time
I haven't noticed it, if it happens. We have a pretty good mix of topics in our list, both happy things and painful things. We complain a lot, and maybe that didn't come through because the retro meeting and the retro email are separate, and the email only focuses on the happy stuff.

We're definitely not averse to complaining! For example, when someone writes a spec that fails randomly, that definitely gets brought up, because it affects everyone's productivity. Someone usually volunteers to help fix it, and we circle back at the next retro to make sure that it's been fixed. Complaining is A-OK as long as you're also committed to finding solutions!
Completely agree with this. Since each one is a massive group of product offerings, it is really difficult to evaluate each on the whole. Your experience is directly tied to your use case.

That's in all of the React licenses.
really the only part that makes bad hires so bad is the impossibility to get them fired at most companies. Even if you hire someone and realize you've made a grave mistake thats obvious to everyone, some stupid moral value or company culture thing will force people to put up with it for 6 months, then have them be on probation for 6 months, then do an evaluation for 3 months, and by the time you finished the process to fire them, they quit first anyway.

That happened at multiple companies I worked at, both small and large, and it just makes me terrified to hire wrong.

If you're in an environment where you hire fast, but punt fast, you can give more people chances to prove themselves. Honestly, it would help with diversity, too. If people are as good as they claim, they don't have to worry about a thing.

It seems like FBs censorship tends to reflect the dominant political force in each nation. It's sort of interesting to observe.

Islamic Republic => Ban(Atheists, Feminists, Gays)

US / Europe => Ban(Right wing political organizations)

Then again, the news only picks up stories it thinks will interest readers. That's a pretty huge bias.
> that burning man felt like mars with a lot of shit and no water

It was one of the dumbest things I've heard in a while. Do these people not realise that these comments will go down in history. Also the "like, I was, like, thinking, like" valley girl talk was very odd (I'm from the UK) to hear as I didn't think people, like, talked like that in real life.
> I don't think Mars is viable until we enter a post scarcity world.

Why? Moving a few thousand humans to mars really isn't that expensive, in money or energy.
Looks like it's made in-house. The tracks they use for webcast intros are apparently collectively known as Spacex FM. I like it. It reminds me of the Eve Online soundtrack.
Thanks, I updated my original comment.
Open sourcing it really only assuages a very tiny sum of people on this axis, as the vast majority of people simply cannot evaluate the code once they have it. They have to trust someone else, the same as they do for vendors.

OpenSSL is a good example of this, because even seasoned programmers trusted the code on the good name of the project and a few notable personalities. All the while told, "Don't write crypto code. It's too hard, let the experts handle it."

And look where that has gotten us. A million eyes all glazed over the same bug.

I'm unaware of concrete evidence that open sourcing code affects security outcomes either way. Do you have any examples?
Where did you get the idea it drives interviewers crazy?

a) I shouldn't ask questions that are in that book, any question found in the wild is banned.

b) I want my candidates to study and show me the best of themselves, and that they want the job and are not wasting my time by throwing their resume on the pile as an afterthought.

c) Cracking the Code Interview is really good at helping you through the algorithmic questions popular on whiteboards. I find the signal:noise ratio on those questions pretty poor, so I ask more straightforward questions that more closely represent things a software engineer encounters in their everyday life. CtCI is good for getting you up to snuff at the stuff you don't do all the time (if ever) just in case you get That Interviewer.

Admittedly, I am but one interviewer and there are many others who do many things many different ways, but I've never heard anyone denounce candidates studying.
Well for one thing living in a gravity well is healthier for humans. We don't do very well long term in 0 gravity. Our systems work best when gravity is helping things along.
Is Twitter a good place to work as an engineer? Does it have a great engineering culture? Does Disney?

I'm just guessing here, but from the stories about how Disney did the whole import H1B people and have current employees train them before firing -- it doesn't sound like they (Disney) know how to treat software developers.
When the pilgrims originally sailed to North America from England, it took on the order of two or three months. A six month trip to Mars seems reasonable in that context.
I watch football. By watching football I have built a good understanding of football management and how to increase the chances of success without having been a hugely successful football manager.

Maybe that's 50% of success of being a football manager. I can learn more than other football managers because I can watch lots of football games on Sky Sports.

That's why many top premiership teams hire their managers by finding the people who watch the most football games on TV.

EDIT: I'm sure there's plenty here who have been in more startups than me, but in the 4 or so I've been in, I've heard conversations between founders and investors plenty of times.

Often little of what comes out of the founders mouth is based in reality. Sometimes they're not seeing reality as it really is, sometimes they're painting a rosier picture, sometimes they're outright lying, sometimes they're tired and not thinking straight, sometimes they've got obsessed by something utterly irrelevant. Sometimes they're not actually listening to the staff, or not even asking the right questions.

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 feel like this is some sort of signaling, a la 'no true programmer uses javascript, because types!'.

Facebook Safety Check is considered as such utility by fb themselves, would I be able to use it without fb account?
Yeah, absolutely no reason you couldn't do this (quickly) with Node. The only reason I see to use Python over Node here is for a smaller dep tree (sane Node development still requires a lot of dependencies) and some more mature CLI libraries - lots of CLI apps are written in Python.
You can do that with safari on iOS if tou don't have the YouTube app installed. It works with any mp4 or mp3 stream too. And you can use other apps, browse other apps or lock the phone and have the controls on the lock screen.

Let it play, minimize the video, switch tab or app or whatever, pull up the bottom controls and click play.
Have you looked into why these people fail? I see all the time claims made like this (i.e. that a large percentage of programmers fail fizz-buzz type questions), but I never see why. Are they morons, frauds, frazzled, confused?
Why is Sam's brother the one interviewing him??
I find it slightly cringy.

What authority does he have / what has he done, that makes him a good candidate to interview Sam?

Continuous Deployment to Elastic Beanstalk with Codefresh
That's true, but the point that many made (and is correct) is that many forms of content cannot be advertised upon under the new policy. In fact, depending upon how YouTube interprets the policy, they can probably block monetization on any video they want, and still claim to be merely enforcing the policy. Finally, it's quite unlikely that this policy will be implemented fairly. If you want evidence, merely know that one of the most viewed videos on YouTube is Nicky Minaj's "Anaconda," which is rife with policy violations, but is on a VEVO channel, and thus technically published by part of YouTube itself.

Do you think they'll be blocking monetization on that?

No, it's not evidence, but until serious enforcing happens, it's the best I can do, and I think it's a reasonable assumption to make.
> Is it practically impossible? Are we stuck with Android and iOS forever?

I think it's pretty simple: people want to use apps on their phones, and no phone OS is viable without a competitive library of apps.

Most major apps are developed for both iOS and Android, and convincing app developers to develop for a third platform is going to be a tough sell, unless that platform is very attractive to users. However, to be attractive to users, it will have to have a lot of apps already...

I suspect that the only way to gain marketshare for a new mobile OS is to ship it with an Android or iOS compatibility layer, which would be pretty difficult to do well. The developers would have to re-implement the entire iOS or Android API, and keep up with all of the changes. If they did that, there would be no incentive for developers to target the native APIs of the OS, because they could just target Android or iOS like they do already. So, the compatibility layer could never be deprecated.

So yeah, I think we're stuck.
> which BTW isn't a "proof", it only illustrates n=1..7 and hints the generalization to the reader

What you've written isn't a proof, either. All of those ellipses are terribly informal. You should really write:

(\Sigma_{k=1}^{n-1} k + n)² - (\Sigma_{k=1}^{n-1} k)²
...

Personally, I find the "proof without words" both easier to read and more convincing than some algebra. I think I'd have a harder time spotting a mistake in the algebra. Do other people really find it easier to find a mistake in a dozen lines of algebra than in a diagram?
In that case it would probably make more sense to just use NativeScript instead of React Native.

No transactions? Single-threaded? Global lock?

Don't want to put anyone's work down, but at first sight this looks much more like MyISAM than InnoDB - and just like this, MyISAM's a helluva lot faster than InnoDB for single writer workloads throwing ACID out of the window.

Just that MyISAM is battle tested over the course of several years. Again, interested to see what comes out of it, but if history is a lesson, it's usually easier to go from correct to fast (PostgreSQL) than from fast to correct (MySQL et al.).
I assume different people do different things...

Tourism would be an obvious sustainable Moon industry. That does fit your description :)
I hate to say it but this is what SpaceX fandom often looks like. I don't think this invalidates Musk's approach, but even on these forums the SpaceX hype is unbelievable and the worst of the worst are usually low information fanboys who aren't really serious about space exploration or space science but like to jump on a bandwagon, as this video illustrates. I also imagine SpaceX marketing wants to surround Musk with young people to make him seem hip enough to constantly go viral in the largely millennial dominated social networks. It'll be millennials riding these rockets, not baby boomers or even gen-x'ers, who be in their 50's by then. Space exploration is a young person's game and SpaceX knows it. The party boy and academically mediocre fratboy won't get a cush job at Goldman Sachs, he'll be the guy mining rocks on Mars. Winning over this demographic is probably seen as important. The first group of colonists will not have cushy lives.

Thankfully, as SpaceX matures and become mainstream, the weirdo element gets diluted. The same way the early web was little more than tribute pages to baby boomer rockstars and endless pages and commentary about the illuminati and the new world order.
>Nobody has tried to make them self-sustaining. It's not as if people have tried and failed.

I'm certain folks have tried on Antarctica (we've had constant human presence there for decades).

However, we still failed even under a much more controlled and hospitable environment - Biosphere 2.

Biosphere 2[1] failed because of our lack of understanding of our own ecosystems on earth. A minute imbalance led to the entire ecosystem failing.

The issue with Mars isn't getting there (or back) - government's have been doing this for more than a decade.

The issue with Mars is getting people there, alive... and keeping them alive for the duration of the mission, and then returning them home alive.

We're only now starting to explore the effects of microgravity on the human body - and having not figured out how to mitigate some serious issues (such as your eyes losing shape, causing you to go blind[2]), we're not going to be able to seriously consider long duration space travel, let alone inhabit another planet.

> Who gets to go?

According to Musk, whoever pays.

> Who rules?

Not to be flippant, but who cares? The worst case scenario is that we repeat British colonialism and the martians overthrow the despotic earth government in a few generations. Same as always, the colony is too far away for the motherland to effectively maintain control. The important thing is getting humans to Mars; all the short-term stuff is important, but it's just small beans in the long run.

> Are we going to Terraform Mars?

Musk clearly wants to. It is not clear how feasible this is with current tech.
Author says the bad outweigh the good, but we haven't fully evaluated the good.

So, question for people who use React Native - how long does it take to go from [100% front end developer familiar with React] ...to [writing solid native apps] with React Native? And how much platform-specific knowledge outside of RN do you need to absorb in order to do this well?
Don't think flavor matters as much as yield -- at least not from the farmer's perspective. Plenty of flavorless vegetables and fruit everywhere, because they're mostly sold by weight, not by flavor or other qualities.
The scenario in which the bet does not pay off results in 1 million people and their descendants being stuck in a terrible situation, with distance making aid or relief impossible at scale. This is something that could be mitigated by making sure that the first planet we colonize isn't some kind of unregulated fief belonging to the first person who threw enough cash at the problem of getting people to Mars.

Which is a long way of saying that I may not be one of them, but I sure as hell will feel sorry for them.

It's a mistake to anthropomorphise HN. I've made it too. We're all in this together, and we're all individuals.

True, people here can be frustrating at times. But the mod team is one of the sharpest, and they cull abuse. And they do it well.

When the abuse is removed, what's left is substance. Sometimes that substance is disagreeable, and sometimes even hostile, but never personal.

It can be un-fun sometimes. But it's been rewarding to watch this place grow and see all of the new and old opinions intermix. Sometimes you end up learning about yourself more than other people, which are special moments. I haven't really felt that on other sites, so HN feels unique and worthwhile.

It's a journey. The community has ups and downs, but Dan (and now Scott) have always taken care of it.
It seems to me if there are actionable items that come out of it, then it will be productive. It is often possible (though not natural for most people) to frame a complaint or criticism in more positive terms. In other words, "I don't like X" can become "We should do Y to make X better."

Most people have no trouble being critical. Getting away from that tends to be hard work and can make it easier to accomplish things.

Are you not interested in why they rewrote it and what made them choose Python? Did they have a problem with it in JS that JS could not solve? Lots of interesting questions here.
Yeah in a lot of circumstances that is true, but the degree to which it is messed up is important. Eventually it will be too messed up right? Eventually the Solar System will be too messed up as well, but we need to start somewhere.

Just comes down to how well prepared you want the human race to be for a planetary or solar system wide disaster.
I'm sorry, but seeing the phrase "blockchain as a service" has been the final straw causing my sanity to snap.

Agreed, when I lived in Miami (last year) knight was funding so many awesome ventures. I wouldn't say they have many developers but they are very receptive to having people come in to pitch an idea and they also host many events to come in and request funding.
Personally I find it interesting observing technology choices of large projects, thinking about if I started something similar, what should I choose...
