This is basically saying, "Let's package together a bunch of volatile high-risk, high-return investments in a completely unregulated market and sell that to people".

Seems like Silicon Valley financiers are beginning to think like Wall Streeters.
You miss the point, imagine you're in a company that makes billions buying electrons for nanocents and selling them for millicents. Now most of the people in the company are not part of the money making apparatus, so what do they do? They think up new things. But that is hard, it is actually much easier to prove impossible thing is impossible.

To its credit you get self driving cars out of this sort of strategy, and you also get less PR worthy work :-)
How exactly is this hackable? Where do I find the documentation to look into whether I can do interesting stuff with it?

Property taxes don't move in line with the market value of housing in California, unfortunately.
It's a joke that the media has continued to dig and dig on as a serious consideration.

Google X's Chief of Moonshots (effectively the CEO), Astro Teller, alludes to the space elevator being a fun joke in his SXSW 2013 speech [1], including confirmation of it never being taken seriously by the team.

He thinks they're installing the Ubuntu Desktop edition on a server.
First impression of the writing room is that it's suffering from classic 'mystery meat' navigation. I think it would be a hard sell to busy clients who hate learning new interfaces.

I'd love to see footage of the user testing on this. I might be wrong but I can imagine many a furrowed brow on initial exposure.

Update - Either I'm really dumb or adding a picture to a post is rather confusing.

I was really expecting a completely stellar UX to be the main selling point. It's a very pretty UX but it's not immediately intuitive. Which leads me to wonder what the main selling point of this actually is. I kind of like the idea of decoupling content from the code that generates the website but that's an abstraction that many will struggle with.

It's not really any worse than what we're currently expecting content authors to work with (Wordpress et al) - but it's not significantly better either. So it lives or dies on the value of the decoupling - which I'm struggling to feel is a big enough win.
The difference is in the effort required to make it run at all!
With all due respect, where does this Rule #4 come from?

I feel like this is the most authoritative list of the Agile rules http://agilemanifesto.org/principles.html and this rule isn't on there.

I saw that OP is the CEO of Aha.io. The ideas that Suzanne is writing about are solid, I'm just wondering where the inspiration for this post came from. Thanks!
I get that. I was pointing out dumb contract clauses in general. As the OP says, there's a large array of these types of things found in contracts, which is why I brought up overly restrictive non-competes and arbitration clauses, both of which are just as scummy as claiming ownership of any IP during the period of employment.
Show HN: Rollcall – An easy way to build a status board for your team
Thank you. This article is so much more substantive that I've changed the current post to point to it, even though the space elevator side-piece wasn't bad.
At the Elm Workshop 2013 ( https://www.youtube.com/channel/UCzbnVYNyCwES9u3dqYZ-0WQ/vid... ) several interesting features like this one were demonstrated. Many of which were brought to proof-of-concept level in 1-3 man-weeks each.
On the desktop you bet, it beats Windows for me. On the server, check the other comments, LTS and the ability to run newer stuff but still be very stable. I really don't see why you're having an issue, Ubuntu Server is plain and works well.
I agree, some accommodation should be made for bubbles. Perhaps the rule should be, not that you accumulate unpaid tax every year based on the difference between what you paid and the assessed value as of that year, but simply that the assessed value is retroactively considered to be the average of the purchase price and the sale price. This would penalize windfall profits, where the market takes a sudden leap and then you sell, but would provide some protection against bubbles.
It would be nice to see a list of the startups that can see resumes (or opt out of some).

If I was at a startup and looking to move to a new one, I wouldn't want it to be public knowledge that I was looking until I at least talked with a couple companies.
By the way, in another HN thread, we posted a $60 discount code "HNApril15" to thank HN community for this awesome and constructive feedback.
This comment is a bit annoying. Had they set out to build an elevator, looked at the problem from a different angle, came up with a different solution that had a chance at working we would all be praising them for going after a problem so many people had failed at before.

The fact that they came to the same conclusion (infeasibility) we now question their intentions/motivations and whether it was a good idea or not.

We either applaud attempts or we don't - but we can't choose based on the outcome of those attempts.
There are an awful lot of people that care passionately about what the leader of the Catholic Church - notional membership 1.16Bn - is saying whilst being pretty indifferent to the US government having the ability to intercept their communications (or unsurprised that it's the case) even once you'd explained who Snowden was and why his revelations mattered.

Unlike many "external" hires plucked from industry to lead university divisions (which doesn't always work out well), Moore is as much of a CMUer as a Googler: He was professor in the school he'll now be dean of from 1993 to 2006, and has maintained strong ties since, so is quite familiar with its culture and operation.

WebRTC Signaling: Here be Dragons
How can children "push themselves such that they can land good grades without needing to study"? I can see not needing to cram for an exam, because a child has already put the effort in, but learning seems to require some form of study.

I think the real danger with this strategy is that when kids are praised for being smart, they seek out things where they are smart, and avoid things that would require hard work. Most worthwhile things require hard work at some point.

Functionally, layered and acyclic NNs are the same thing. An arbitrary acyclic NN acts the same as a layered NN with some of the weights fixed at 1 or 0. (Replace any edge crossing n layers in a non-layered acyclic NN with a chain of n nodes to get a layered NN that responds to input the same as the original non-layered NN.)

I suppose there may be some cases where the extra speed you get by omitting the intermediate nodes pays off. However, I can't imagine a situation where you'd know enough about the problem in advance that you could design the NN's graph in that level of detail.
I don't want to specifically say this site is good or bad, but I've had really bad experiences with sites of this sort.

Essentially, sites of this sort were all just recruiters trying to farm up candidate contacts, and all you are left with is just spam.

My advice to underdog.io: tell us who you actually are. What's your name? What experiences do you have? Your "About Us" says nothing about you, and makes me suspicious that you don't want to put yourself out there.
As someone who has been doing DevOps for 20 years, since long before it was called "DevOps"...

First, DevOps has degenerated into a meaningless buzzword to rival "Agile", despite the good ideas and good intentions. Every day, I have recruiters looking for "DevOps". A couple of years ago, they'd never heard the word.

Second, DevOps is actually getting strongly biased toward Ops, often to the exclusion of Dev. In the eyes of recruiters and much of the industry, it's become synonymous with "Chef/Puppet/Ansible automation", a set of automation tools. That's stupid.

Third, and this is what matters to me... DevOps is (or was meant to be/should be) more about organizational structure than skills. As the author points out here, specialization is good and necessary. But specialization comes with bureaucratic compartmentalization that makes working across org boundaries very difficult. When you have to climb four or five (or more) layers up the org chart to find common management for both the dev and ops sides of a project, then the dev team has no authority over and very little way to communicate with ops, and vice versa. For most large organizations, the dev/ops separation is necessary - developers get locked out of production systems to keep them from legal exposure to customer data (HIPAA, PII, etc), and to keep them from accidentally or intentionally altering production in a way that it might break.

Read Gene Kim's excellent quasi-fiction book, The Phoenix Project. It covers a lot of the issues of DevOps as fixing communication patterns in large organizations. You'll see how little of it is about tooling or "full-stack", and how much is about clearing bureaucratic obstacles to effective communication.
Well you can't just fly 22,000km of cable into space with a rocket, and then drop it down. Using balloons to cover the first few km could save a bunch.

Also, there's a rather large difference between a multi-billion dollar internationally supported scientific operation, and a few million dollar marketing stunt.

If you can make a few hundred meters long carbon nano tube (which we can't right now), what's stopping you from making a balloon with a circumference of a few km, and how much cable could you lift up how high with that?

Since gravity decreases quadratically, the first miles are the ones that count.
> I want to underline that in most countries in Europe, the language of programming and tech environments is mostly English (documentation, internal communication, white-board meetings). So just English is enough in most cases.

That is not my experience of working in Poland. As a native, I've worked in multiple projects and Polish was the communication language in all of them. I am sure there are jobs available where everyday communication is in English, but my guess would be that they are in minority.

There was a period, including the time Ubuntu launched and got popular, that Debian was infamously slow to update stable. Along came Ubuntu with a clockwork-like release cycle (every six months IIRC) and up-to-date packages, even in LTS. (In fact the Ubuntu elevator pitch, as far as I was concerned ~10 years ago, was "Debian packaging but with regular releases.")

It sounds like (?) Debian has tried to put those days behind it. But sysadmins of a certain vintage will always remember when Debian allowed itself to languish. Ubuntu, meanwhile, has maintained a very good track record with regard to timely updates and keeping LTS packages patched, etc.
One of my co-worker and one of my friends drink at least three cups of coffee in the morning alone to get the day started. The chemical tolerance they've built up scared me off.
Oh, I see! Thanks for the explanation.
Saying "DevOps person" is like saying "Agile person". I think it's a fundamental misunderstanding. DevOps is about getting development and operations to communicate directly and work cooperatively, without impediments beyond inherent complexity.

A '30 day trial' could be most useful for getting customers signed up. It could also be useful for developers that have launched a new site and need to make sure it all looks good during the initial phase - they could 'abuse' the service, however, in so doing, they would spread by word of mouth the value of your product. Imaginably the service would be signed up to thereafter as it would be ingrained in as valued and required.

I also think there is utility in being able to send the screenshot to many people. For instance, an ecommerce website with sales scheduled for the weekend where the prices are supposed to change automatically. Here it would be useful for the person who puts the prices in, their micro-manager and their micro-manager's micro-manager to be cc'd in on the screenshots.

In this day and age the desktop view is not the be-all and end-all, for a premium the mobile view could be recorded too.

Right, that makes sense now. Thanks!
There's no evidence they put any serious effort into actually trying to build a space elevator. The article doesn't discuss any alternate cable materials they explored/considered, nor does it even mention any of the many other aspects of designing a functioning space elevator.

If they were even remotely serious, they'd be continuing work and research on everything else relating to building a functioning space elevator and waiting for materials science to catch up, or better yet directly contributing to the advancement of the materials.

Edit: I'm not criticising Google for looking at space elevators. Hell I do applaud that, and I think it'd be a great direction for them to explore. What I'm upset about is Fast Company's journalistic standards about covering it. Google X mentions they looked at space elevators and Fast Company would have you believe they threw millions of dollars and man-hours at it and actually tried to design one.

Journalists apparently have no idea how to cover scientific topics. If someone reports they've found a chemical that's shown to target and destroy a specific strain of cancer cells in a petri dish under laboratory conditions then Fast Company would be reporting that they've cured cancer.
> Also being slow isn't necessarily a disadvantage if it could be made much cheaper.

silicon (processed sand) will always be cheaper. In order to make (nano) artifical biological parts, you have to use really expensive chemical building blocks, or, if it's biologically (and not petrochemically) derived go through expensive finishing steps.

> Biology can rapidly self-replicate out of everyday materials.

Then you're adding at least a micron of space overhead.

> It can also run efficiently on chemical energy and even sunlight

Also true of mechanical parts, for example palladium nanoparticles running off of peroxide, or light-driven silver nanoparticles. running off of sunlight is a nontrivial process for biology (turns out oxygen wrecks a lot of really important enzymes), and biology is actually not very good at it.

San Francisco is the 20th densest incorporated place in the US:
http://en.wikipedia.org/wiki/List_of_United_States_cities_by...
Cudahy, California is a city that's significantly denser than it.

It's the 2nd-densest large city in the US, but that's because the dense core city is its own incorporated area, as opposed to most other American cities, which annexed many suburban areas throughout the 20th century. And most American cities are some of the least dense in the world— San Francisco doesn't even rate on a list of world cities:
San Francisco doesn't even rate on a list of world

And it's still only half as dense as Brooklyn.
I hate this trend that startup homepages seem to be going through. They don't seem to actually explain what their product is. All I can see from this page are a load of assertions that either:

A) It's not the same as thing X
B) It's better than thing Y, because of Z
C) Their Q (which is part of their product) is really really good!

To someone landing on the page, that doesn't tell me what they do on a grander, more abstract scale, it only gives me a pinhole view of parts of their app, and thus prevents me from seeing the bigger picture. I'm sure the product as a whole is great (after all, I know each part is great), but I still have no idea what the product as a whole does!

I've read the FAQ, and I still can't quite figure out what this is offering. Can anyone condense this into a single paragraph (or better, sentence) that describes concisely, and completely what prismic does? I really can't fathom it from their website...
Hey, I'm one of the people working on this.

That's totally a legitimate concern. I can promise you we aren't recruiters. It's just a side project at the moment, so we didn't want to draw too much attention to ourselves.
Exactly. With no knowledge of who my information is going to I can't agree to submit an application. Privacy is one reason; not having your time wasted if the companies aren't something you're interested in is another.
Nagios is not a monitoring strategy
Nagios is a great tool, but by itself it is a poor substitute for a monitoring strategy
I don't think that using a Raspberry Pi as a poor mans Transputer will be very satisfactory.

The INMOS T800-20 was 20mhz and did 10 MIPS. However, it had four links, each doing 20Mb/s, so it can communicate at about the same speed it process data.

By comparison, a RaspberryPi is ~700Mhz and 847MIPs, but proportionally IO is extremely starved. It barely is able to keep up with 100Mb ethernet which gives only slightly more bandwidth than the the Transputer had 30 years ago.

There are numerous cool things about the RaspberryPi, like the graphics, the community support for cool software, the HD camera option (and the company making an HDMI input adapter board to connect to the camera interface on the RPi). However, it strikes me as a terrible choice for clustering and I feel sad whenever I see someone talking about doing that.

A much better choice would be an ARM chip with built in gigabit ethernet. One possibility would be to find PogoPlugs. They aren't just a bare board, but they can often be found for under $20 with hardware gigabit ethernet, an 800mhz or 1.2ghz processor, and 128-512megs of RAM. Another option that is a little more expensive would be to use Biostar J1800NH with 2 gig RAM sticks, pico PSUs, booting from cheap flash drives, could probably be put together for $105 per node.
If your production deployments are fundamentally different than your dev deployments, you're doing it wrong. For the most part, you should only be localizing a common deployment pattern.

I've suffered through enough three week deployment cycles because the prod environment is almost nothing like dev and everything is done manually. I think I know what "doing it wrong" looks like there.
I thought https://browsershots.org/ was the big one. I suspect there are many.
Nagios is a great piece of software, but if you are going to use it as your monitoring strategy it is a mistake. Mike Kavis discusses on DevOps.com
Those are great pieces of feedback. We're definitely add this.

Intentional training: Learning with a purpose
It was pretty straightforward in our case. We had to show them that we had use cases that weren't feasible with the default access level and also demonstrate that we weren't competing with their user experience at all. Not sure how much it mattered but we had been using their streaming API for almost as long as it existed.
One of the core challenges with the space elevator concept is that they need a cable that can reach from the earth's surface to somewhere beyond geostationary orbit, with exactly how far depending on how they want to arrange the counterweight. The midpoint of that cable will have to support the weight of all of the cable that's below it, and that's around 10-15k miles of cable. So we need a material out of which you can make a 15k mile long cable that can hang free, supporting its own weight. Making it thicker doesn't help, because then you just add more weight that you'll have to support. We need a better material that has this level of strength when manufactured at scale.
