Ask HN: How do you build a dev, ops, IT community around your open source tool?
The open source solution we created is an app and infra automation tool. It does more than our competitors, but they have well known names and money which helped their communities. If I don't have that, what could I do to grow our community?
(July 2016)
Yes and no. They haven't maxed capacity, they get paid if people wait in line in the park. Selling fewer paak day tickets at higher prices is better experience for customers.
>you could only consider that to be ES if you're building a database.

I poke around in the guts of databases, so that's what I meant. The WAL is ES in the context of databases. So I guess ES is the generalization/abstraction(?).
If we ship code that runs on SuSE 234 and RHEL 345, that's what we test on. If we run on our own hardware or AWS, we pick a distro and test on that. I don't care whether it builds or runs on a laptop; I don't write twitch games and interesting problems don't fit on a single machine anymore.

It's been a decade since I worked at such a tiny nascent company that all the software was written in just one language. Language packages almost never express dependencies on either system packages or other languages' packages, making "bootstrap to the point of being able to use all of the languages' toolchains" a manual process that lacks any guardrails. Nothing ensures you have a httpd version that's compatible with all your apps, because each of them just sort of assume httpd is out there somewhere without saying anything about it. Staying on the right versions of shared libraries is even more error-prone since the system package manager literally doesn't know you're using them.

If you want to read upstream security advisories and use such bleeding-edge software that even the bleeding-edge distros don't trust it yet, you're basically rolling your own distro that only exists on one machine in the world (because some languages' package managers aren't idempotent and symmetric) and is supported by nobody besides you. I'd rather delegate that to the people who specialize, because the best case is that I don't fuck it up too badly, I'll never add value that way.
I wonder if these posh locations are worth it. I'm sure it attracts some students, and there's some advantage in the proximity to hip startups also in city centers. But students are low income during the program and hardly have a chance to do anything outside the office, given the workload of these bootcamps.
A counter-argument is that the Lightening work is a proprietary development outside of bitcoin core (lead by Blockstream) and the work is even patent-encumbered.

They state the ip is for defensive purposes only - however that is questionable given that anything they implement, automatically becomes prior-art. It is also contrary to the spirit and practice of the majority of crypto/alt projects.

It is unreasonable to attack miners for having interests, without disclosing that other interests may benefit from the current levels of network congestion that a skeptic would say are caused by having artificially small blocks.
My guess is that the profitability of different bootcamps varies with the policies / niche that those bootcamps have adopted. It seems likely that all bootcamps have high operating expenses / lower margins than a pure software business may be capable of.
They did the same in California and they have 4 parks next to each other in Florida.

They wouldn't do it if there weren't a profit.

Say you're an airline, and you notice that all your planes get fully booked, but on every flight, 2 to 5 passengers do not turn up or miss their flight.

That means that you can easily sell 2 extra tickets for each flight. That's free money (as good as; fuel consumption will go up a tiny bit)

Now, there's the rare case where too many passengers turn up. So, you pick out a college student or backpacker who is happy to take a flight an hour later in exchange for money, a free ticket for another flight, or whatever. That costs you a bit, but as long as it is rare enough, the net result still is extra money, and, ideally, everybody is happy.

Airlines have departments that compute the ideal amount of overbooking.

So, how can it be legal? That's easy; if you book a flight, you accept terms and conditions, and no government has seen reason to make it illegal.
I like Detroit. Okay, fine, no I don't. But I live in Michigan and love the rest of it. Low cost of living, great schools, reasonable opportunity for educated workers. And I love the weather. Great for all seasons of outdoor activity.

I'm curious if Liaoning (outside Shenyang) is the same way. (I've had a long-running fascination with HeiLongJiang for reasons I don't understand myself, though I've never been there)

Google pays academics for key support
There are videos of HAM guys scanning randomly through the spectrum to find people. I remember one video, 80% of it was static, and then a blip.. the guy (somewhere in the US) started to poke around that freq. another blip.. then a voice. It was a Russia dude answering, it was surreal.

Airlines are different: people typically visit web sites to compare prices, not service.

I think you'll find hotels targeting backpackers overbook, too (if they allow reservations, at all)
Honestly, I'm going to shrug my shoulders. Not to dampen anyone else's celebrations and enthusiasm. That's just how I am about these kind of things. Like on most Birthdays, the orbital relationship of Earth to Sun isn't even within millions of miles of when I was born, so I'm like "meh". Except for my DD's birthday, but that's because it's special to her.
The interesting bit is that it was already happening on the PC world, with C only being used for OS APIs on Windows and OS/2, but most people were actually using C++ (OWL, VCL, MFC), Turbo Pascal for Windows followed by Delphi, VB, Eiffel, Ada, Oberon, Component Pascal...

Then the UNIX FOSS, written mostly in C took over, and set us almost 20 years back in security and safety.

once plain HTTP is no longer supported by cargo-cult-security-conscious browsers

There already are people talking about such possibility and some even appear to believe it would be a good idea.

Of course what happens then is that without Let's Encrypt you are stuck paying other CAs to have anything published on the Web at all.

<tinfoil hat on>LE is a conspiracy of CAs to phase out unencrypted HTTP and ensure them infinite money stream.

<tinfoil hat off>Even if it isn't, LE will disappear five months after their mission is done because what the heck, why bother.

I just wonder if there is any reason to believe that users of LE are any smarter than kids accepting free candy from pedos? Maybe there are reasons but I just haven't heard them yet.
They can at least do right recommendations if adblock detected.
$18 is not in the neighborhood of $5. Also I doubt the keychain type can achieve mass adoption, it's the in-USB-port kind that is actually convenient, and those cost $50.
What's interesting to me is that for all my appliances in my house (different brands), I've been able to repair each of them (microwave, air conditioner, washer, dryer, dishwasher, and wine fridge) on my own, using some basic instructions on the internet and a part that at most has cost $50.

I believe we're in a golden age for self-repair (particularly with YouTube videos), but I keep hearing about how everything is throwaway. Just the other week I repaired an iPhone 3GS we had been using as a baby monitor until it was dropped, for $4 (including shipping!) to replace the screen. That's amazing!

For those that do a Google search, and buy some parts on eBay (although I got an obscure a/c part via Amazon Prime), it's never been easier to repair your devices.
They worked quite smoothly for me. I actually liked StartCom's login process.
I was a part of Matt's first cohort at Dev Bootcamp and he saw us all the way through the program. I remember telling him afterwards that he was the best teacher I have had and I think everyone else in my cohort felt at least similar if not exactly the same. It was teachers like him that made Dev Bootcamp an awesome experience for many. He developed extra lectures beyond the curriculum on stuff like SQL injection and really thought out how to present them effectively, sought out things that we were struggling with like at one point I think it was scoping in Javascript when we had primarily been dealing with Ruby, or this one time where he was really excited to show us something he repeatedly said would "blow our minds.” I think it was predicate methods and how you could compose them to make new ones. I remember thinking at the time something like “That’s it? Or am I missing something…” Still, it was the effort and caring that stood out. I also remember him staying late with us to refactor a Javascript challenge that was already meeting specs to be object oriented, even though it wasn’t part of the challenge.

I think it was experiences like that that make so many DBC grads so fond of it and why so many graduates still come back to pair with current students. Yet it wasn’t all good. I saw a cohort after us, if I recall correctly have around half of the students help back and have too many students and not enough teachers. Still, I think they tried to do the right thing most of the time. Why else would you allow students to repeat portions of the course and take up to 6 weeks longer instead of just churning through students as fast as possible or make a special effort to try to make the program more accessible underrepresented persons?

Personally, I was miffed by some stuff like finding out during the course that average salaries were lower and average time to employment longer than listed on the website and not seeing an urgency to update those numbers publicly. Or hearing about a plan to try to collect money from potential employers upon hiring a grad when the job search already wasn’t easy and they had already collected thousands from each student in tuition. Like student needed another barrier to being hired. I felt bad for people coming after me having to compete both with more Dev Bootcamp grads as more campuses popped up on top of all the new competing bootcamps, but I really hope most people made it work. DBC did always say that it wasn’t graduating there that’d get you a job, but what you make of that experience and how far you continue after, but still I always wished they were more forthright with their statistics and outcomes.

I don’t know where I’m going with any of this. Guess I'm saying it was a special place, but also a mixed bag in my experience.

That's how undergraduate University education works in Australia (at least it did when I attended. Perhaps someone younger than me can comment if things have changed in the last 20 years).

Effectively the government pays your undergraduate university fees. There is then an additional tax applied against your salary, after it reaches a certain threshold. This of course results in jokes that Arts graduates may as well be enjoying free tertiary education.

I think this is a much fairer system than being asked to pay upfront and perhaps taking out a student loan in order to pay fees. The Australian system allows any student with the ability and desire to attend University (it's not completely perfect, but it is much better).

> However, any changes require consensus from the miners who create Bitcoins and process transactions, and because it's not in their best incentive to do anything to reduce those transaction fees, no change has received majority consensus.

This is an unfortunate misunderstanding on the part of the miners, and the math is really simple: imagine a network on top of Bitcoin, e.g. lightning.network, which can process 10 million transactions off-chain and settle it on the Bitcoin blockchain using only a single transaction. Imagine if every one of those 10 million off-chain transactions paid just 0.01 cent in fees... this would earn the payment processor $1000, which can only be realized by publishing a Bitcoin transaction, in competition with everyone else making a lot on off-chain fees. The result is that off-chain profits (in the form of fees) would allow off-chain payment processors to pay huge blockchain fees, because they can deduce it from the profit they've made on off-chain fees. Nothing, in my opinion, will increase Bitcoin fees more than layer 2 protocols creating more users and transactions (because fees are paid per off-chain transaction).

The point some miners are missing is that one billion off-chain transactions each paying a 0.01 cent fee is more profitable than 2,000 on-chain transactions paying $1 each. And if everyone is able to earn $100,000 in fees by publishing a single Bitcoin transaction, this must push up Bitcoin fees, since people will be competing on getting into the chain with the bidding power from their earned profits.
Digital but physical viruses? Yeesh!
I think the car analogy is not quite correct. A car is able to dynamically change its velocity, bitcoin can't easylie do that. It would be much better to find a genereal solution that fix that problem altogether, instead of finding a solution that works for the next few years and might require future forks.

There are no specific hardware requirements for any of the levels of autonomy, that I'm aware of.
If you are keeping all the forked coins, you probably don't have a strong ideological opinion. It's not about being 'wrong' in this case, it's about ideological alignment. If you follow my advice, you will more or less end up with the same amount of money as you started with, regardless of where the prices of the coins end up (as long as you wait through the early volatility stages).

If you aren't ideologically aligned, holding onto all forks is a perfectly sane choice.

Wow, staggering numbers!
I can only speak for Lamdbda School, of course.

The original document is called an income share agreement (ISA). It's not a debt instrument or a loan, but is actually a legally binding "equity" stake in a student's future income under specific circumstances for a specific amount of time. Lambda, for example, takes a percentage of income for two years, only if they're working in a software-related field, and only if they're making above $50k/yr. We also cap the amount paid over the two years at $30k, regardless of how much a student is making. So, yes, if they don't get a good job, we never get paid. That only seems fair.

As for how it works practically:

In conjunction with the ISA, each student signs a 4506-T or 4506T-EZ (or any successor form) with the IRS, which effectively copies us on their taxes.

Students self-report their salary, and we adjust payments according to their reports, until year-end reconciliation, which happens around tax time. We get their taxes and double check that their self-reporting has been accurate, and adjust accordingly.

Should a student default, we have the same remedies that any other private lender would - we reserve the right to report to credit bureaus, we can sell the agreements to collections, etc.

If the soft fork goes through, the Chinese miners are going to attack the chain.

If the soft fork fails, Core developer Luke-Jr said they'd change the Proof of Work algorithm and possibly create an altcoin (or bitcoin if enough follow).

This is like a Russian Roullete situation. The gun's loaded, all signs point to neither side conceding. It's the cypherpunks vs the corporate miners (plus some former devs and very credible people).

Detroit is a good comparison but perhaps apart from one thing: Shenyang has BMW's state-of-the-art factory that produces the new 5 series (and soon the new X3). Auto industry is one of the few highlights that actually thrives in Shenyang. Type in keywords 'new bmw 5 series production' you get footage from this factory. They even use exoskeletons. Pretty cool.

https://github.com/Microsoft/react-native-windows what about this?
I'm glad someone said it. Merit= very short bootstraps. This is a much denied truth here in the US, where everyone is so desperate to believe in our national mythology of anyone who works hard can do anything and be anything they want to. This myth can't even carry an aroma of truth these days. No one who has "achieved" anything ever wants to get real and admit how they really got it--- they'd rather tell you and themselves a great American tall tale. Becase if it isn't earned, if it isn't "merit" in any real sense, then what? Then does everyone have a right to opportunity? Yeikes. We don't have enough opportunity for that. Instead, we avoid facing these issues by focusing on "diversity" now... but only a certain very narrow definition of diversity, and only when we want to raise ourselves above others of merit for being so meritorious as to think of diversity. Then, we wonder if "diversity" has made us less competitive. The only answer here is money. Money. That's it.

Could imagine that Google's infrastructure is bigger. Their cloud service is clearly smaller than AWS but they have much more computing demand than Amazon has for their main business. So overall Google could be ahead of Amazon.

Logistics infrastructure of Amazon is not the largest either. In the US, Fedex and UPS will have more infrastructure. Not that many warehouses, but when it comes to distributing items they should be larger. Worldwide, DHL Group could be the largest. They have a substantial freight forwarding business so that they will move far more goods every day than Amazon does.

The important thing, though, is that no one has both of it in one company. We'll see how valuable that turns out to be (maybe not at all, maybe very).

The first rule of eventsourcing is don't eventsource EVERYTHING.

Eventsourcing requires really, really detailed analysis of your boundaries (and no small bit of experimentation) to get right, even when you've done it before. It should really only be applied to the areas of your application that are going to see a real benefit from it. My proxy for measuring this is "how much money does this group of features make for me?" If the answer is some version of "none" or "none, but its a requirement to have it anyway" then I don't try to apply ES to that area of the application. I never use ES on user records anymore, for example.

I'm sidestepping your actual question, but mostly because your use-case is something I consider to be a bit of a canard. To answer it though, as others noted, "it depends"—I model projections with actors, which means all events DO come through a single process handling events sequentially (and this is a very common way to do it.) But because I've got tons of these actors (one per stream that's actively running), there's no real bottleneck—this is also one way you guarantee ordering within a stream.

Higher up in the stack, at the eventstore level, you'll probably have a pool of processes handling writes and routing events to the correct handlers/projections, but this is an implementation detail that can vary widely. The advice to not get bogged down in the details early on is good—the thing i see almost every developer new to ES do is get mired in the basic "how do i implement this" question, and that's really not what's going to kill your project. Not understanding nearly as much about your business and the software boundaries in your system is where most projects go wrong.
Alexander Graham Bell and Customer Support
I fully agree, but you cannot oblige everyone that touches the code to have the same care, and so the typical "C with C++ compiler" idioms sneak in, thus decreasing overall safety.

This is specially the case in the majority of enterprise software that doesn't use any kind of static validation tooling, or CI builds.
Another part of the value of a university is that they factor in SAT scores heavily into admissions. SAT scores correlate strongly with IQ.

Hiring based on IQ tests is illegal, but hiring mostly from certain universities is not.
