I'm pretty sure the plan is to put this one in a museum. Later variants are supposed to be easier and more reliable to re-fly.
Ask HN: Google Cloud Certification vs. AWS Certification
I'm curious if anyone has taken both the AWS certifications and the Google Cloud certifications.

Long story short - 20 years a sys admin / developer and I've never pursued a certification in anything. I've done just fine, career wise, but I think it's time to get something on paper.

I'm almost done with some AWS systems architect associates certification online training - planning on scheduling the exam this coming week or next week if I do well on the practice exams. I intend to take the first 3 at least (systems architect, developer and Sys Ops)

Can anyone compare the difficulty of the Google Cloud certs compared to AWS? I get that their different proprietary systems and in my opinion with different purposes - I personally feel Google Cloud is more for big data type situations where AWS is more for scaling and serverless architecture (please, correct me if that's wrong) - BUT - systems are systems and a basic knowledge in 1 should be helpful in the other, no?

(I'm a Linux guy - No Azure here...)

I don't intend to take the Google Cloud certs until after AWS certified and have produced some production sites to get real world experience with it. So this is really just a "I think I'm gonna do x" right now, then a "I'm doing it next week" type question.

The operator overlooks my pet peeve when it comes to comparing floating-point numbers: in C++ the "standard associative containers" (std::set and std::map) are based on ordering using an less-than relationship which must be a "strict weak ordering". Many times, the methods suggested for comparing floating point types do not satisfy the requirements of "strict weak ordering", and in this case the C++ standard says you've entered the realm of undefined behavior. In the code at $DAY_JOB, "undefined behavior" turned out in this case to include such pleasant side-effects as double frees(!).

Specifically: when you have a less-than relationship "<", then !(a<b) && !(b<a) implies that a and b are equal (a==b). And if a==b and b==c then it must be the case that a==c, or the requirements of the ordering predicate are not met. Unfortunately, under most of these FP comparison schemes, for numbers a and b that are "close but not too close", it's the case that a<b, but for x=(a+b)/2, a==x and x==b!
This is especially funny considering the huge discussion recently about rewriting curl and then the entire world in Rust, but imagine you lived in a world where the magical "better tool" already existed and all you had to do was discover it.

Leaving fantasy-land aside for a moment, this morning you woke up in the real world. In the real world, that tool does already exist, and it's called Mercurial.

If you try command-line Mercurial for long enough to get past the initial "oh no Windows/macOS/Linux got updates and moved all my icons" muscle-memory-refresh phase (and especially if you last long enough to get into revsets and templates), you'll find it extraordinarily difficult to go back to using command-line git. Your power grows with Mercurial as you learn more about it because you aren't constantly fighting the complete absence of idioms and opaque "man-page" style of documentation that puts a slab of inscrutable text front and centre and neglects to provide simple examples for common problems (apparently we have a perfectly good Stack Overflow for that).

The git boosters will respond to this by saying, as they always do, "yes, but the real power of git is in the model of the information under the hood. The CLI is just an interface, if you don't like it you should spend months studying the internals and build your own workflow on top of git". Again, back in the real world, who has time for that? Or the interest? Especially when, as I already mentioned, that tool does already exist and it's called Mercurial and you can get started with it right now.

Both tools can do close to exactly the same things under the hood with differences that won't make a lick of difference to the vast majority of users. The user-facing differences are where it really matters: one tool has an excellent CLI which is clear, concise and discoverable; the other has github. Damn. Lousy network effects.

You're more right than not. A minimal amount of technical computing skills are useful things to teach to everybody in grade school, but the value add of computers falls off pretty fast.

And the problems with computers in the classroom are not limited to grade school! Nobody should use a laptop in class.

One could argue whether they're truly private sector, but they still haven't quite displaced ULA. In 2016 there were 12 ULA launches, 8 SpaceX launches, and 2 by Orbital ATK. Looking at other countries, there were 20 Chinese launches, 18 Russian launches, 9 European launches, and 7 Indian launches.

Compared to the Swedish model where the government handles the whole process, I find the Canadian one really interesting. Many of the success stories I've read in Swedish media is from more rural places, small villages with ≈ 100 inhabitants, where the community have stepped in and tried to help in the ways they can. And on the other hand, the worst stories are from places where essentially no "native" swedes live and the circle of unemployment and low language skills etc is just perpetuated.

The swedish response have mostly been plans to place immigrants in more affluent neighbourhoods, which of course have caused NIMBY-outcries. I would be _really_ surprised to see the model mentioned in the article implemented in Sweden, but it would be interesting.
Absolutely, and you've said it better than I did.

As a nit, wasn't Kant's Critique of Pure Reason written in part as a response to Hume?
No, because they screwed up and enabled his camera feed a few seconds before they told him he was live. That would have been edited out if it hadn't been live.

Either that, or they're going for that extra touch of verisimilitude, I guess.
I'll get on that right away. Great idea!
The problem with this argument is that "being rich" is relative. Anyone want to wager that the author's "maximum moral income" is approximately the same as his/her income?

Isn't someone who makes $50,000 /yr extremely wealthy from the perspective of someone whose income is ~$5,000/yr (like a lot of people in India[1])?

Come on A.Q. Smith - how can you justify even owning a computer when people are starving? Is it immoral to waste money on dinner and a movie when that's more money than some people make in a week?

Something to think about: pretty soon there will be nothing strange about a rocket that has flown before. Contrast it with the feeling you have for a 737 that has done 2500 starts and landing prior to you going on board, it's a sign of confidence that it did that. Now it will be many many years before there will be boosters with numbers of take-offs and landings > 20 or so but at some point insurance premiums for unflown hardware will be higher than for hardware that has been flown before.

Huge game changer this, also in the frequency of launches.
So they are supposed to be trying to recover the two fairing halves this time around - any news of that?
On the prelaunch video, they suggeste a try for at least 10x.
No one's going to point out the brand new addition to the English language in this title?
A few families and church groups in my Canadian network have adopted syrian families. It has been a truly positive experience to hear all the ways people are offering to help (food, shelter, jobs, transportation, socializing, childcare). And of course the handouts of delicious syrian food in return. On a trip to Halifax I bought some chocolates from a syrian business, and they later ended up on the news for their success.

This is the Canada that I love. And that positivity and love absolutely trickles down through your network of peers. It's about people helping people.

Does anyone else here have stories?

I hope one day that America starts a similar program to make amends for the awful effects of Trump's executive orders on immigrants, americans, and travellers stuck in limbo.

It occurs to me that many Americans are crowdsourcing for healthcare of their citizens, while Canadians are crowdsourcing to welcome new people to their communities. I don't mean to offend, but it seems like moving up maslow's hierarchy to me.
You know there is absolutely no reason for you to "believe" anything about Blue Origin, right? Google, Wikipedia and Blue Origin's own website is 3 seconds away.
might be people focused on their job, like getting a satellite at the agreed-upon position :)

(but I agree, forget this satellite stuff, show me where the trash landed, and tell us where the fairings are!)
Reminds me of how well the German pows in WWII integrated in rural farming​ communities in the USA, to the extent that they were allowed to.
Ya, a fair point. It is an undue burden on the schools. Now they have to function as school, (in many cases) parent, and language/culture teacher also.

I just think if we are going to have large scale immigration this is worth funding somehow as I believe in the value of assimilation.
I think part of the challenge is manufacturing and handing out a distributed system to nontechnical users and then trying to debug their issues without having central control. (Or any control, really)

As someone who built an OSS synced storage server, scratching my own itch was pretty easy but responding to bug reports that are far outside of my use cases can get tedious. And somehow it feels like there are just so many, compared to other areas.

Edit: git-annex supports encryption and webdav remotes (and thus, ownCloud/Nextcloud/others) and it works pretty well.
Fantastic!!! Being able to watch a reusable rocket land perfecty, from my mobile phone while casting to a TV, over a computer network​, while located in southern Brazil makes me SO PROUD to be human!
That's one of their strengths - a company as large as Amazon can easily spread itself into multiple concerns without endangering its core business.

They can even shut out competition by adding new Prime benefits for various services.

Even the risk is mostly offloaded to existing companies. All Amazon has to do is wait to see what is viable/sustainable, figure out how to undercut their competition (likely their own customers on AWS), and essentially reach out and take "the rest of the pie" from those customers.

It's brilliant.
>>>I kept pinning my happiness on future events.

This is true. I don't think you have to go to the extreme of living a nomadic life to address it, but I definitely feel where the author is coming from.

The first time I realized this, in conjunction with how much of what my expectation of happiness comes from media, it was a really jarring experience.
They wouldn't have a monopoly since there are plenty of other launch services out there (ULA,Russians,ESA,etc). The fact that SpaceX will probably be able to do it for much cheaper doesn't factor into it.
To be fair, most classroom software that I've seen is terrible. Couldn't her hesitation to learning tech be more because we've spent a long time giving them bad tech, so she stopped trying?
I'm not sure how valid it is, but i read somewhere that Blue Origin and SpaceX are both shooting for the same target, but taking different paths. Blue Origin is doing Reusability first and orbital second. SpaceX went Orbital first and Reusability second. although to me it seems spacex is clearly ahead.
Bash scripts -- write scripts, check them into git, make sure they are idempotent and repeatable. Whenever you start something new, reuse them and fix whatever broke since the last time.

For testing the scripts, I've used virtualbox -- install the latest ubuntu server LTS into a VMinstall your ssh keys, dotfiles, etc but leave it otherwise bare-bones. Then, clone it (this takes just a few seconds) and do your testing inside the clone. When you need a clean environment, delete the clone and create a new one... Makes for fast iteration on testing that install scripts always work. Don't configure anything by hand -- learn enough sed/awk/grep/etc to modify what configs you need without invoking an editor.

If you need to scale this up to something real and in production on multiple systems -- then start learning Ansible / Salt / etc. Doing in those systems what you now have documented in bash scripts will be some work, but doable.
If you can keep 12 problems constantly present in your mind, you're a genius.
I think we can acknowledge this without feeling like we're 'bad-mouthing' teachers at all. Depending on the grade level, content knowledge and expertise is only one part of a good teacher's skill set.

Salaries are unequal, so that naturally reduces the prestige of being a teacher. It's also a traditional "feminine" job with strong parenting/caregiving elements that further chips away at its status for some.

I don't judge anyone for seeing teaching as a "plan B"; however, the significant turn over/drop out rate of teachers would call into doubt whether it is as safe + easy a back up career as we culturally project.
Floating point math is a bit fuzzy, so many languages will round to the nearest integer if the float is within a certain margin.

Numeric types are meant to be exact, so they will be represented as an exact value.

YIPPEE!!! That was amazing SpaceX. Thanks Elon!
That's why this is so big, dropping the costs significantly could easily pull a significant fraction of those other launches to SpaceX. Pretty soon the ability to re-launch the same booster will be considered a must-have feature if you want to be in the rocket business, unless you fly missions so close the maximum payload or trajectory that recovery is impossible.
Maybe we could borrow the Statue of Liberty for a while. Park it it the St Lawrence.
but they are not getting paid for an api call, they are getting paid for successful transactions going through their api. And if I can hammer the API with useless unworthy listing calls while big-customer cannot initialize transactions they are losing money.
Not sure why this ended up on HN today, but this is a classic text read in many introductory courses focused on philosophy of mind and consciousness.

I quite like the paper. I once wrote a follow-up paper about how one might interpret it now that we know about neuroplasticity. That was fun to ponder.

I looked at a specific experiment where researchers managed to map visual impulses from a camera to an electrode "pixel grid" physically placed on the tongue, such that the visual inputs were "mapped" to corresponding locations on your tongue. It was shown, in the research, that people could catch balls thrown at them blindfolded using this setup, and after a relatively short period of sensory adjustment. They would actually "see with their tongue".

You can read about that research in this 2003 article from Discover Magazine:

http://discovermagazine.com/2003/jun/feattongue

The Nagel question then, is the fact that I experience vision a certain way really an essential aspect of "what it's like to be me?" Or is my consciousness a "further fact"... something running in the background of all my senses, no matter how they are wired (or rewired) over time? This is sometimes referred to as the "hard problem" of consciousness, summarized nicely in Wikipedia here:

ooooh totally was. He was deeply affected by Hume's attack on causation, so tried to come up with a coherent response. Ended up positing a whole bunch of wacky and (I think) true things about our embedded cognition, so I think it's probably fair to say that Critique of Pure Reason is the result of his beef with Hume.
Don't ever let anyone tell you that something is impossible.
Or when the sponsors refused to let the kids' parents work through a simple issue like the school bus not showing up, and instead injected themselves into situations they didn't belong in. That was selfish and self-aggrandizing.

I think that's incredibly unfair and I'm frankly astonished you'd interpret their actions that way.

How many people step in when their loved one is failing because they care about them and want to help, and don't want them to be discouraged if things go poorly?

That's exactly the dynamic at play, here. In fact the article goes out of its way to point that out.

It's such a common human experience that I can't help but wonder if you're going out of your way to view their actions in a negative light.

As for the rest, well, these are my own impressions based on my life as a Canadian, and my extensive exposure to American culture... take them with a hefty grain of salt. shrug
That's exactly what I thought too. I assumed it went kaboom and they cut the feed. What a nice surprise when they called out a successful landing!
A while back I wrote a similar post that focuses more on the math, and how one might discover this organically (well, maybe)

Putting up a childish billboard of questionable strategic value promoting a candidate for president is "screwing with something with such high stakes?" Hyperbole?
I can't wait until I have a talk with my kids when they realize the significance of this day:

Kid: Daddy, ou mean when you were growing up, they threw away rockets each time?

Me: Yes

Kid: Doesn't that make them expensive?

Me: Yes.

And then not long after will be the other talk:

Kid: Daddy, you mean people used to be in charge of driving themselves in cars?

Me: Yes

Kid: Did people ever die?

Me: Millions

Good job Elon and SpaceX, get some rest, and then focus on the Model 3!

Elon: We have proven what can be done, that many said was impossible. drops mic after SpaceX lands flawlessly
algolia is the best, great article. I was always curious how algolia is fast like this.
The diversity that actually adds something to the understating of a problem, is the diversity of ideas and points of view. Putting different races, genders, sexual orientations, etc, just for the sake of appearing diverse, adds nothing to solve any problem.
There are actually even more things broken. Just incredible, for one simple feature change. Every reply-to-self now helpfully includes your name right below your name. It's confusing, looks ridiculous, and it's everywhere now. Also, you should see what notifications look like now that threads can have unlimited participants. Each notification lists every. person.
No: SpaceX is launching satellites into various orbits, which Blue Origin cannot do yet (and cannot do with their current rocket).
... you can say that about any historical event ever and massage it to fit your narrative.

The commandment for Muslims to fight wasn't sent down till a year or two after the emigration, so they were quite literally not allowed to fight or "subdue" or "coerce" anyone. There's a /tonne/ of evidence that the emigration was peaceful (though there were certainly subgroups opposed to it politically and ideologically). It is quite literally one of the least contentious pieces of Islamic history.
My heart attack moment was during the launch when I started seeing flame flickering around the tops of the engines... and then I thought to look at the altitude indicator, and realised they were at about 10km, and it was just the plume expanding as the atmospheric pressure dropped.
SpaceX would still have to deal with scheduling: making enough upper stages and having limited launch/landing pads they share with NASA/ULA/ATK. So those with less cost-sensitive payloads (governments) would probably still pay a premium to launch their payloads sooner rather than cheaper.

Could you elaborate on this?
"I thought, “Hey, I’m a Web Developer™! I should use JavaScript for this because JavaScript is the best lol!” "

While that's clearly meant to be somewhat of a joke (from a medium account called dailyjs as well), it's this kind of annoying attitude that has lead to js being forced into lots of other avenues.

Also, is js really even the best tool for this? I feel like you're going to get far better pictures and faster results from language closer to the metal like C/Rust/Java(???).
The link is to a livestream and I didn't get here in time to watch the landing live, has a recording of the landing been uploaded anywhere yet?
Someone on reddit said it was an ablative coating. This was also a heavy launch, so it's not surprising they'd be hitting the atmosphere faster.
I think that an expectation of global standards is unrealistic. When you arrive in a new city, you have to learn plenty of things like where things are, how to get around, and what laws differ. I don't think that asking people to figure out what should go in which bin in the city you just moved to (an event that typically occurs annually at most and a question that takes a few minutes of Googling to answer) is excessive; it's just part of the new city learning curve.
I agree entirely. Assimilation is key to successful large scale immigration. I've always wondered why folks want to move to America to have a "better life", but then fail to learn English. If we're going to have immigrants, we need to be prepared to set them up for success.
Speaking of German technical jargon, one thing that bothered me probably more than it should have was that in my Norwegian-German wordbook, "computer" ("datamaskin" in Norwegian) was translated as "festplatte". Obviously "festplatte" would mean "harddrive", not "computer".
>The divide over immigration isn't over immigrants -- but illegal immigrants. Huge difference. The "anti-immigrant" meme is inaccurate. It's "anti-illegal immigrant."

And yet this pic is at the top of the /r/The_Donald right now. Trump voters are afraid that America will become Mexico. But they're also afraid that America will become Syria or Afghanistan or Sweden or Germany.

The grid fins are painted with ablative paint that's supposed to burn away while protecting what's underneath. Same with the legs. But they do suffer damage during re-entry as could be seen on photos of them from previous landed boosters. I'm fairly sure that's all expected and accounted for.
