Thanks for the great series!

Is there any chance you could go into how you developed a relationship with your ODFI? Like how you found them, how early in your development they were willing to work with you, what type of compliance checks they required, what type of fraud prevention you guaranteed, etc?

This seems to be the biggest obstacle as a startup in the very early stages of exploring ACH.
I don't think CoreOS does anything special in this regard.

It should be possible via cloud-config to change the runtime config of the docker service[1], in which case one could set "--icc=false"[2] to enforce stricter rules about inter-container communication on a particular docker host (e.g. a coreos droplet).

[1] https://coreos.com/docs/launching-containers/building/custom...

[2] https://docs.docker.com/articles/networking/#between-contain...

EDIT:

Okay, I see you were asking about regulating network comm between containers on separate docker hosts, i.e. coreos instances.

That's a good question! I still don't think CoreOS addresses that concern in any special way at the level of iptables and routing (but I could be wrong). What it does give you is the ability to control service affinity with respect to your fleet "units". That way, you can be certain that docker containers which need to be "linked" in order to communicate properly (e.g. you have set "--icc=false") will run on the same host.

Full data recorder info being sent wirelessly is a big "ask." You'd be transmitting full cockpit audio in real time (security risk?) so you'd need encryption, and you'd also need it to work over the ocean which even getting radar for is a huge pain.

It isn't impossible. With enough cash it is very possible. But you're looking at a new array of satellites just for this purpose alone, new standards (i.e. secure rather than insecure uplink), and plenty of expensive certification. Maybe 1 billion budget could do it? Maybe more (if it isn't US or Russia, so launching satellites gets more expensive).
BTW, the random module has a "choice" function, which takes a sequence and returns a randomly chosen element from it.
So instead of "result[randrange(len(result))]" you could have "choice(result)"

I've never understood this either. I ended up buying the bigger battery for my GNex (the official Samsung extended battery, not a 3rd party one). Battery life is such a critical factor in smartphones, but time and time again it's ignored by the big players. With Android phones, Motorola has the best track record with regards to taking battery life seriously (the Droid Razr Maxx HD was almost the last phone I bought for this very reason).

When I worked at Boeing on gearboxes, I did some work to calculate the loads when the gear drive ran into the stops. To do that, I had to calculate the rotating moment of inertia of the gear train.

Another engineer looked over my work, and asked "what book did you get these formulas from?" I said the shape of the gear wasn't in a book, so I had to derive it.

He was shocked. I was shocked that he was shocked :-(
This concept seems to elude people, but the value of a company that never makes a profit is precisely $0.

As others have stated profits = revenue - expenses. In this case they are positive on the right hand, even if slightly, so they are in fact making profits.

Your time horizon is also wrong and assumes that there needs to be a singular point where the top level goal becomes making profit, rather than profit being a byproduct of a top level goal of adding value.

I also disagree with your assertion that value comes solely from profit.

>I was fortunate in winding up at Caltech, which had a policy of open book / open note exams

There is a widespread miscoception that openbook exams are somehow more better and forward thinking. You don't have memorize the exact formula but you still have to memorize where that formula is, one is just memorizing different kind of information.

Learning is about learning how to learn a particular subject . A good exam should test you on weather or not you can pick up/learn a new (slightly advanced) topic on your own based on your current knowledge. It should test you on what you can learn not on what you have already learnt. Open book exams don't address this fundamental flaw.
Absolutely understand what you are saying. But isn't that by definition a hot potato Ponzi scheme?

I mean there are large monster e-commerce giants in other nations, it is a very real possibility that Amazon will have to battle with some company at scale who is also in the razor sharp margin mindframe.

Its not impossible to imagine a world where amazon gets into a war with an Asian e-commerce giant for domination of the worlds e-commerce needs. If this does come to fruition this battle will probably not be resolved until 2020 ish time frame... so its a real possibility that amazon could be in business for 30 years, never return a profit to its investors, and NOT end up ever ruling ecommerce.

I haven't seen any insurance products that thrive on the risk that ODFI takes, but the ODFI does minimize their risk by requiring the originator to keep a collateral account to which they'll take money from should they incur any kind of loss.

The ODFI does place daily (soft) limits on the originator, and the amount of collateral you have to put up is proportional to your daily limit. It definitely varies from bank to bank and is a largely of a factor of how much your bank trusts you and your past ACH history with them.

I was calling him out on the frivolous and unfunny quip, not implying he isn't a serious programmer. And I don't mean to single him out for criticism in particular, I was just reminded of the Foozles phenomenon:

Perhaps I have a chip on my shoulder about this, but I actually did my undergraduate CS degree in Cambridge before I knew anything about the world so I am at least somewhat qualified to comment on that milieu, from a political point of view. It's cosy but relevance to the everyday life of the masses is not a strong point. I don't have any comment on whether JavaScript implementation details have political consequences.

I don't recall a single exam question that was merely "plug the numbers into a formula and write down the answer" which is what you seem to be implying.
Can anyone in the banking industry explain why there is no security on ACH similar to how there is for credit cards?

20 years ago when I first wrote a program to generate ACH files it struck me as crazy that all that was needed to take money from someones account (given an existing ACH relationship with a bank to send the file in the first place) was an individual's bank's public routing number and the individual's personal checking account number - both of which were at the bottom of every check they write.

I get that fraudulent charges can be reversed, but that's also true on credit cards - so why the lower security on ACH?
The reason I wouldn't use a rich text editor is it leads to "support issues".

It wasn't because the implementation was buggy but rather the fact the end-user thought it should behave like word and just copied/pasted stuff.

Rich text editors are more complicated and tend to have usability issues. I had to support one for a year with very, very average users who used the application infrequently.

Right, but the "new economy" twist is that Amazon likely doesn't know most of these companies exist outside of them being in a database somewhere. It's providing services in a self-service, one-size-fits-all kind of way.
> It should test you on what you can learn not on what you have already learnt.

I'm not sure if this is the right approach, either, especially when materials get harder. It sometimes takes a lecture or two to fully teach a concept. You don't usually have that kind of time when you write an exam.

What I really enjoyed are my fluid dynamics exam. We learned all the theories in class + a handful of example scenarios. The exams had radically different scenarios than what we are used to (although if you look through it, it's the same and you apply the same principles to solve them).

I don't know if that's the right approach either, but it was fun to think about.

It's a vacuum. They suck up dirt. Is it really that much of a stretch to imagine that a vacuum's bin would therefore have dirt in it? The entire point of a clear bin is so that you can see how much dirt is in it and whether it needs to be emptied.

The marketing photos show a new, unused vacuum. Duh. The alternative would be as odd as a Johnson & Johnson selling bandages by using a photo of a gory, infected, pus-filled wound on the outside of the box. While that may very well be a valid example of its use, I don't really see many people wanting to buy anything marketed in such a manner.
It's also a unit of control, which has increasing value as the value of the company increases.
Well, I'm thoroughly convinced. I want to take this class!
While I agree that etcd and config management systems do not solve the same problems, and esp the same way, the use of etcd by all of your services does enable your examples.

For instance, there is a tutorial on using vulcand as your http load balancer, which is driven by configuration in etcd. A tutorial on the CoreOS site shows you how to use this to cleanly deploy a new version of an app as new versions of a container, and to rotate them into the LB and to rotate the old ones out.

You can also connect a script that controls firewall rules based on etcd, its' changes would be reflected almost immediately, rather than the splayed 30-60min period of seemingly-randomly-applying-changes you typically see with config runs of tools like chef and puppet.

I've been trying to figure out where tools like chef, fabric, and docker/coreos/etcd/fleet will play together, what the boundaries will be, etc.. In situations where I'm using Docker and CoreOS, I don't expect to use chef, but I'm not sure it will be used for things like database servers, which we typically dedicate and tune hosts for.

It would be nice to see something like chef running on CoreOS for, say, user management so that people who want to talk to, say, fleet aren't required to all ssh as 'core'.
Yeah, that was my thought too.

I can't speak for NACHA (the governing body that came up with ACH), but I believe the goal was to make it an electronic equivalent of a paper check.

If you think about it, it's pretty easy for someone to create a fake check based on someone's account/routing number (which, as you correctly say, it's not private information because is on the bottom of every check you write), put it in an ATM machine and debit someone's account without their permission. ACH is really no less secure than the current security protocol for checks.

Not that I think this is a good idea, but this might be a possible explanation of why ACH was designed this way.
That is a really impressive milestone. Best of luck in continued growth.

All of that sounds very familiar. Astronomical sunrise/sunset times aren't an accurate guide to actual perceieved day length. Topological obstructions, like nearby hills, and in our climate, overcast skies block or decrease sunlight penetration.

Near my office, I've measured daytime illumination. At the least obstructed spot, midday it was 40K lux in the sunny summer, but late fall 9K was as good as it got when moderately cloudy.

In late fall it's identifiably daylight (if barely) at 9:00 and getting dark by 15:00 even though sunrise/sunset times promise 8.75 daytime hours in early December.

A couple of notable consequences are a high rate of seasonal depression, and widespread vitamin D insufficiency. Light is a cue for circadian rhythm, and people sensitive to fall/winter darkness often benefit with phototherapy. I'd make sure to take vitamin D supplements too, usually 2K IU is a standard recommendation.
Good grief. I said the _implementation_, not the language. They all use mutable state.

I don't think that's necessarily a bad thing (not that you were saying it is). I've enjoyed venison burgers/steaks, but most the time I'd rather taste the seasoning or the rest of the dish that I add meat to. I don't need flavor from meat, just that good ol' umami.
Amazon has actually been better at this kind of stuff than Google. Since their acquisition of Kiva Systems, they have built what is by far the best automated warehousing/logistics platform of any company in the world.

The future of EVERYTHING is going to be very reliant on AI and robots. My view is that the last 20 years have been the Internet revolution. The next 20 are all about AI and robotic automation. Both disciplines have existed for a long time, but they've hit a tipping point where price and effectiveness are putting them within reach of total ubiquity.

I'm disappointed this kind of disingenuous Gladwellese keeps making its way to the HN front page.

Despite what the article claims, "pretesting" is not a thing (yet) in psychology. The whole premise of the article hinges on one unpublished study by a single research group [1], one that didn't even administer a full "prefinal" at that. The effect is intriguing and might or might not be "significant" (no way to verify oneself); but either way a single, unpublished, unreplicated study does not an "exciting development in learning science" emerging from "a variety of experiments" make, as the article pretends.

But then it wouldn't make as clean a narrative, would it.

Capons: Are Chickens Without Their Testes a Forgotten Delicacy?
Right, and you can achieve service discovery, orchestration, and convergence driven by something like zookeeper or etcd, rather than by bulky config runs.

While I enjoy working with Chef, have had some pretty reasonable times with Puppet, these full-run tools do have issues sometimes where you introduce a narrow bug in your user management or some other code, and all of a sudden you can't update some random conf file that happens after it. I've also seen tools like capistrano and fabric bastardized to allow this sort of precise updating, but lose the cohesion of typical config-managed systems.

With something like etcd, certain problems are solved by not relying on static configuration. That is the paradigm shift, and it is similar to Hadoop. When I've built Hadoop systems with puppet, we simply wrote out the same configs and files on every machine, then chose which services to start, and via zookeeper things like primary / secondary failover take care of themselves.

Both Amazon and Google are very smart. Amazon seems to have a greedy algorithm with regard to new tech. I mean, Amazon seems to keep automating the least efficient thing - http://www.kivasystems.com/ for example.

Google is much more forward looking, looking for big changes, like self driving cars. I can see google taking over more markets like they did with search. "more wood behind fewer arrows" was the saying.

Amazon is much more broad, if Amazon has something, they'll rent it to you.
Ask HN: Any ideas on how to thumbnail 2M images?
Hi,

I'm a developer at the New York Public Library and we're currently evaluating ways to create derivatives (i.e. thumbnails) from a library of 2 million master images.

At 5 seconds an image using a tool like ImageMagick (which might be optimistic), it will take 115 machine days.

Any suggestions or tips to speed up the process?

Edit: Original images are scanned TIFFs, 25-30MB each.
