> The blockchain community is immature and historically unwelcoming.

I can't disagree too much about the immaturity, but you don't see too much more of that in the deeper technical circles than you might see on the Linux mailing list. Room for improvement? Plenty. But it's also not grossly out of line as long as you are in the right places.

The 'unwelcoming' bit though is more justified. Blockchain design is like cryptography - security is very important, and one tiny mistake means that your design is completely unviable. And if that tiny mistake occurred early in your design process, it may be too deep to be easily routed around.

Designing secure blockchains is very hard. As a result, the first year or so you try to improve on blockchain systems you usually end up with a bunch of broken stuff that nobody appreciates at all. The same is true if you are trying to make a better hashing algorithm, or doing quantum resistant cryptography. Except with blockchains people haven't learned to expect it to be this difficult to innovate yet, so it feels a lot more hostile.

That will fix with time. As more things blow up in production, people are realizing more and more that blockchains are tricky, and that good designs take a lot of expertise, a lot of collaboration, and are very rare. That will make it seem less unwelcoming when your intro to blockchains is 'well, this thing you are proposing doesn't work for at least 10 reasons, and here they are...'

Help.com | Multiple Positions | Austin, TX | ONSITE | FULL TIME

It's 2017 and customer service still sucks. Companies have tons of data about you (what you've purchased, every page view to your site, every interaction you've ever had with them). However, that data is stuck in a bunch of fragmented systems and even the customer service systems they currently use don't connect their own data between different channels (tickets, chats, phones, etc).

Help us eliminate terrible customer service experiences by building out the world's best customer service and support platform. With workflows shaped from our time at HostGator (10M+ customers) and GoDaddy (10M+ customers), and technology skills developed from building cPanel, Cloudflare, CBS Sports apps, Node itself, and more.

We are predominantly in the JavaScript/Node.JS ecosystem, specifically a React/Redux stack on the front-end with Jest and Enzyme driving testing. On the backend, we launch Node.JS services of sizes ranging from micro to large. Everything is built and deployed in containers on Kubernetes and we're building for scale.

Our product is real time, distributed, and relies on a great user experience. Since we're a communications platform, we strive for 100% uptime (multi-zone, multi-region, horizontally scalable, cross datacenter replication). As such, simple things on a single application/server become fun challenges in a distributed system :)

Open Roles:

- Quality Assurance Engineer (JavaScript)
- Software Engineer (Front-end - React.js)
- Senior Software Engineer (Backend - Node.js)
- Software Engineer (Backend - Node.js)

Perks:

- Working with 2 Node Core Contributors and tons of other smart folks
- Founders have helped build many successful companies before (cPanel, Cloudflare, HostGator, etc)
- On-site lunch
- Well tested code and agile practices
- Your code is used 8+ hours a day by our customers so you'll gain massive amounts of experience and feedback

Currently Predominant Technologies:

- Node.JS
- React/Redux (Jest, Flow, Enzyme)
- Docker / Kubernetes
- Google Cloud Platform, AWS
- Message Queues (NATS, Google Pub/Sub)

Anything that's related to profits and democratized will attract all kinds of characters. Democratization lowers the barrier and profits provide the incentive.
The choice to corner cryptocurrencies and choose to see the shady characters in this combination is an artificial one based on what you can and choose to "see". The same shady characters are in finance, fund raising, and perhaps around your desk. They may be less obvious or you may be more tolerant towards the corporate backstabber, but they're still there.

>I think the main difference is that there is a chain of people who profit from selling to their 'downlines'

How is it different from 3rd party Apple resellers?

>Apple sell a product that the majority of people like

As does Herbalife.

>they are actively trying to sell directly to the customer

Herbalife lets distributors handle sales, not very different from Apple's resellers.

>They use networks as it is their only option in many markets and once a phone is sold to the network it is then sold to the customer, there isn't a series of transactions with each level profiting of the previous level.

Apple -> Authorised Resellers -> Stores. While this is not Apple's only channel (because they have their own stores plus online shop), it is one of them... and there is multiple transactions with each level profiting.

Evidence of exposure to architectural patterns of a large, high-scale web application (e.g., well-designed APIs, high volume data pipelines, efficient algorithms)

While the company is Cyndx Networks our latest product(linked to here) Doppler is a tool focused around helping companies raise funding including a tool for matching you to the right investors, helping you manage them through a fundraise process with a built in CRM and data room and a dashboard to keep your board/advisors/investors apprised of what's going on
during the fundraising process.

As a multiple time past founder we built this because we wanted to see it exist - now that we have companies using it the feedback has been great.

In a nutshell its like having an analyst to tell you who to reach out to (we have an algorithm that recommends investors to your company and tells you why) plus docsend for giving access to your docs and then a complete dashboard to see who accessed them and when at scale all powered by dataroom providers you'd typically pay a lot of money for.

You are being downvoted because this is the wrong thread.
Because all workers should be entitled to a minimum standard of living, even if they are in a field with a labor surplus.
Cryptocurrencies aren't going away. Which means that if your primary motivation to not work on cryptocurrency is that it wastes energy, then there's a whole lot of room for you to be making it better, and that is a stupid motivation. I'm not saying that they are obligated to work on it because it wastes energy. But the comment I was responding to implied that distributed systems engineers didn't want to work on blockchains because they are wasteful - which is clearly illogical. That'd be like Elon Musk not working on electric cars because they're inefficient. Or Solar cells. Etc, etc..

If you are wondering how Stripe could even start with just 7 lines of code, it's a bit misleading:

With Stripe, all a startup had to do was add seven lines of code to its site to handle payments: What once took weeks was now a cut-and-paste job.

I.E. the simplicity of the Stripe platform (taking only 7 lines of code for developers) was how they succeeded, not that they built a startup at first with just 7 lines of code.

Ask HN: Best way to transition from .net to open source tech like python, etc.

Any advice ?
I'm really not trying to be pedantic, but that's not true. The UK has no written constitution but it does have a constitution. It's important to make the distinction because it is entirely possible that this proposal is unconstitutional (and I wonder if that's why the Home Secretary is asking for companies to voluntarily adopt it rather than passing legislation).

It smells unconstitutional to me because it is an attack on individual sovereignty and the right to privacy. I would love to hear an expert or two give their opinion on the matter.

>However, the theoretical maximum energy efficiency of this unit, assuming no heat losses from the tanks, will probably be poor compared to LiIon or pumped storage

But Li-ion is orders of magnitude more expensive than what they're proposing (no matter how cheap the cells are getting), and couldn't possibly be deployed at this scale. It's more useful for stop-gap loads when you need instant discharge. Pumped hydro is only possible when the local geography is perfect for it and there is an abundance of water. The reality is that our future will require a host of different technologies like this working in synergy to provide grid scale energy storage. No single solution will become the standard.
> Are there any examples of well-known apps from large organizations that aren't excessively large in size?

This is nothing new. Look how much memory your typical Java desktop app, or worse, your average Java server app, uses. As soon as you have enterprises involved where it's regular occurrence for devs to be outfitted with the shiniest and beefiest (as perks or per standard company policy) developers won't care about resource usage until it's so excessive it either slows down their machines or accounting knocks on the door and asks who ordered dozens of x1.32xlarge machines...

Seriously, another huge problem is assets. In ye olde PC days, you included ONE version of an image and that was it (okay maybe a 16x16 favicon for the small start menu and a 32x32 one for desktop)... these days with loads of different combinations of resolution and DPI, and across multiple platforms (if you're doing a Cordova build and don't split the assets before packaging), stuff can and will grow.

I live in the south and have a 2 hour flight to Boston. I was flown up there about a month ago for a day of job interviews, but didn't get the job. A job before I move is the goal but I'm not sure how easy that will be since companies are wary of relocating--a friend of mine (same company and same experience level) after months of searching for a job in Denver finally moved there and had 5 job offers within a month. So perhaps I am too encouraged by his good fortune, but I feel it cannot be that difficult.
This might just reflect on one of the more sinister aspects of democracy. You live life expecting eventually "your people" will take over some day. That generations prior were monolithic and wrong, and that since your own peers share your mindset it must mean people your age are just wiser.

Eventually, you realize that you were just in the intellectual minority of a generation that was majority unintellectual. Like every generation pretty much ever. We have just become extremely effective in isolating ourselves from exposure to the real "average". But even online, there is a vast difference between the ignorance of certain sects of Facebook or the comments on a yahoo news story and the trolls on 4chan - the later are still "our" people. Even if they want to abuse their intellectual leanings, they still grew up with that mindset. The average Facebook post or comment on a Fox News or CNN story reflects the broader, more general mindset much better.

And the outlook isn't good. For any generation.

quite so.
Indeed. The Carnot Cycle has nothing to do with the efficiency, since it can be reversed in what is typically referred to as a "Coefficient of Performance", which is always bigger than 1 (assuming you aren't using straight resistive/friction heating). I seem to recall from Thermos lecturers that a CoP for consumer fridges is often in the 4 - 6 range, and it increases the smaller the difference in temperature between sink and source is, inversely to the Carnot efficiency.

That said, due to heat capacity of pump components and conduction losses, I would be surprised if the total cycle efficiency was above 80%, putting this well below gravity and battery storage schemes. Maybe it is just incredibly cheap? Water does have a high heat capacity...
Sure its safe when you dump all your waste in another state. If your state that created the nuclear waste had to keep it, it would be a different story.

That's a bit of a mistake. It doesn't rely on inefficiency it relies on economic costs. At the moment, hashing is a form of economic sunk cost. If you invest in hashpower, you can't split it without reducing your probability of success. It's an unforgable economic burden. Proof of stake architectures attempt to do the same thing with the currency of the network itself. There are lots of arguments about whether or not this is truly secure - but anyone on here telling you they know it's not is pretty much an idiot. There are tons of proof of stake coins operating successfully right now. There are no known attacks on these coins that allow you to do anything untoward (if there were, they'd be exploited on one of the many existing PoS coins).
which of the mutually untrustworthy parties will operate the ledger?

customs agents don't trust shipping companies, shipping companies don't trust their customers, shipping companies might trust most customs agents in western countries but they operate everywhere, and there are, as i understand it, a number of other middle-men involved in the process, who probably aren't trusted much either.

i don't see how a privately operated database would solve any of the problems, or appear more secure to the folks not running the database. (certainly it would be cheaper.)
