>While you may know what ERP stands for, you're missing the bigger picture on what modern ERPs do.

I think his point was that ERPs are specific proprietary applications that are not used as tools for programming, and wouldn't ever show up in any CS curriculum. I didn't see any statement on what ERPs are capable of doing.

>But, my college degree's in management and economics, so things like accounting and business processes were already something I had passing familiarity with. ERPs will make little to no sense if you don't understand how corproate accounting works.

>You might find a business-related class that covers ERP-related topics?

I'm not sure why your response was framed like a disagreement.
You're right about the operating system not being flexible enough, however it is now.
Truly impressed by Halide after watching the video. This could really be a game changer for writing e.g. deep-learning related code such as Convolutional Neural Network evaluation and training.
I think this just means that the random number selected for children from a couple was allowed to range between 1 and N, whereas for the smaller populations, it is between 2 and N. It doesn't mean all couples generate 1 child.
Actually, we kind of discovered that, unless we radically cripple our model (eg. by removing the first-class-citizen property) Turing-completeness is basically irrelevant either way.

I basically just chose to keep it in there because it makes a few contract types easier.
I agree. I understand time and frequency domains reasonably well, but I still do not have a clue how Fourier transformation gets me from one to the another. How do the elements in the animation correspond to the terms in eg this equation http://www.texpaste.com/n/v6sjue00 (which is the Wikipedia definition for discrete Fourier transformation)? I don't even understand what the equation itself is supposed to represent, last time I checked a sum produced a single number, how does that represent a function in frequency domain? I guess the subscript k has some significance, but the animation does not help a single bit here
> Example: get the gradient/color values along a horizontal line from x0,color0 to x1,color1.

Sadly, colors don't blend as easy as coordinates: http://www.stuartdenman.com/improved-color-blending/ ... but in general I agree.
250K kph is nowhere near fast enough, by several orders of magnitude. That gives us a 4k year journey to the nearest star system, which AFAIK is not thought to have any habitable planets.

And that's a tiny probe, close in to the sun. Leaving the solar system with that kind of velocity is a whole different problem. Voyager 1 is leaving the system, doing about 17 kph, reportedly. As far as I know, we don't have anything right now that can do much better than that.

According to everything I've read, sending anything at all out of the solar system at a high enough velocity to get to another star system is way beyond any kind of engine technology we even have on the drawing board. We could probably build a fission engine if we really wanted to, but even that's still orders of magnitude less than we need. Much less propelling an actual starship, meant to contain hundreds or thousands of humans and keep them alive and happy for the journey, at those speeds.

I do believe that we'll do it someday, but it's going to require propulsion technology that we can only imagine right now. Anything like FTL or wormholes or whatever is pure hand-wavyium at this point.
When you factor in free app downloads, the average selling price of iPhone apps is 19 cents:

http://appleinsider.com/articles/13/07/18/iphone-users-pay-a...

To make even $100 per device, an average user would need to download approximately 1700 apps over the life of the device!

Simpler math: $100 in profits would require something like $370 in app/media purchases. (30% commission, 90% margins on operating iTunes/App Store)

To say nothing of the fact that this would require Apple to turn their back on the past 37 years.
The last paragraph is spot on. People circlejerk around Google being a saint company. Not that much here on HN (because everyone heard about their support related to AppEngine, AdSense, ...). But even here many are defensive when it comes to web and browsers in general. And don't you dare mention Google was evil when there is MS on the other side.
Very interesting article. There are tons of ethical and practical concerns above and beyond the genetic situation, which itself might be fixable well before a ship capable of such a journey was ready.

However, what I found weirdest about the article was not the topic itself, but this line: "He calculated the trajectory of each population 10 times, then averaged the results. (With one exception: The starting population of 40,000 is so large that it takes 18 hours to complete each simulation, so he calculated that trajectory only once.)"

Even without considering the possibility of running the simulation on 10 colleague's computers or spinning up cloud VMs or any number of workarounds, how rushed was this project that a week's worth of 18 hour MATLAB runs was considered too much work?
I use FollowUpThen - https://www.followupthen.com/

It does a lot of stuff, but I have it email me every Thursday to remind me to take the trash to the curb. Its just an email, not a calendar alert, but it keeps the clutter off the calendar and I usually see an email within a couple hours anyway.
So it is essentially a credit card rate.
They said the same thing about the mortgage market abuses - "Oh, it's just a few bad apples."

No. No it fucking isn't. Furthermore, letting the bad behavior go unpunished means the 'good' behavior gets driven out: https://en.wikipedia.org/wiki/Gresham%27s_law

"Good" HFT strategies are nowadays obvious by one very salient fact: they're not very profitable. Most market making now, for instance, is simply cover - noise trading, basically - designed to disguise the real bad behavior (that the OP conveniently states is just 'very rare'... heh).

HFTs aren't dumb. They know that any regulator or prosecutor will find it very hard to dig through the trading data and discern evidence of illegal behavior from individual trades.
They recommend to buy this 4K display (it is not produced by Apple) if you own a Mac Pro 2013 or a MacBook Pro 2013:

I find the key is, using the metaphor of the tech tree, to distinguish between branches (inventions which lead to other things) and leaves (which don't, at least not in a relevant timescale) and - this is the hard part - to ruthlessly apply the rule only work on branches.

It's easy to see that things like video games, artificial life and fart "apps" are leaves and we shouldn't spend time working on them. It gets painful when we apply the rules to things we value more highly. Astronomy, particle physics, space flight, fusion power: these are all noble pursuits, at least the first two or three were branches in the past, by rights they should all be branches today. But they're not. They're leaves. That's the cold fact of the matter, and the world has to be dealt with as it is, not as it should be.
Thoughts on Charter Schools
Yep. Although they apologized publicly for it and came out being a much stronger organization.

Their apology (not half bad): http://www.givewell.org/about/shortcomings

Deceit in lending is not uncommon among microfinance organizations, but it's surprising to see it from a YC-backed company. I look forward to Zidisha's response, I'm sure they'll shed more light on it.
So all the children would then be educated by a robot ai?
Authenticity?
It's bullshit because Apple is successful because it doesn't follow every trend and it's not serving the low margin non premium segment.
On the flip side if you regulated the outsized returns down to a more reasonable size then that would legitimize the business and dissuade the scummy sharks (who are drawn in by the outsized interest). Was that not proposed?
AirBNB is Ruby/RoR and Java.
>Oracle is hardly the only company in Silicon Valley, much less the world, known for ruthlessly pursuing intellectual property claims [it's hardly the only company in the valley with a reputation for requiring developers to dance to its tune, either].

Does a company have to be the only exemplar of a bad behavior for it to be pointed out? That's a very hard standard to meet that would suppress any discussion of corporate decisions.
Then it comes down to the monetary and environmental cost of the replacements.
Carriers still get much higher ARPU from iPhone users. While that is true, the subsidy will remain.
Consistency in video support is almost non existent. So serving variations for every platform is frequently better simplified. Rather than come up with every possible test we simply broke it up into two categories, those that need flash (HDS) and those that don't (HLS). I'm sure there are some browsers that would work for HLS that are getting served HDS and flash, but they still work, and we got fairly wide compatibility without having to spend too much time maintaining compatibility lists. This might not be the best way to run a video specific site like youtube, but being a moving target, I wouldn't be surprised.
Done. At least I think so; it gave an error message when I posted the reply, but the reply seems to show up anyway, let me know if it doesn't show up for you.
Startup idea dispenser
Yes, there are two questions here. One is whether or not Zidisha is misleading people, and the second is whether whatever they are actually doing is a good thing.

I think the article makes a case for the first, but we shouldn't immediately conclude that means that on-average-very-high-interest microloans are somehow intrinsically the subject of moral disapprobation (as I've seen suggested in at least some comments).

I think there is a (third) real question as to how to brand high-risk services like this.

EDIT: I think this top level comment (currently) below by jfasi is highly on point: https://news.ycombinator.com/item?id=7547117
As I understand it, the main issue with HFT are two fold:

* some cases of insider trading at under-a-microsecond rhythm, that sound like faster-than-light favoritism but are actually covered by existing legislation (you just need to update judges and the SEC on basic technological feasibility);

* dangerous unmanned behaviour -- flash-crashes.

Front-running has always been presented as controversial at best, i.e. taking cents from people who could spare dollars; more often illustrative of finance’s excess (spending the GDP of a large country to establish even faster lines between cities already well connected, not that makes any more sense than blaming Formula 1 racing for going above the legal limit).

I understand his passion, and the “I’m a geek and I work for a small company facing Goldman” inferiority complex must be crushing -- he writes himself ‘A fervent defense’. However, that seems to be missing the key issues most people have with such technology left unmonitored.
Yes. I agree that the author seems to want to completely ignore the fact that it is a 1 time fee vs an interest rate.
When someone makes a phone that separates the screen, input and processing into three physically different pieces (different in shape, volume, mass) that are connected by a micro local network I will buy it in a heartbeat.

All modern smartphones are far far far too big.
I think there is a lot of nuance being left out in these types of defences which are misleading. For example,

> Note that the market maker at no point had the ability to change any order in response to Big Joe.

But they sort of can, specifically the canonical example in Lewis' book is that HFT market makers change their standing order on other markets faster than it takes the orders of buy/sellers taking liquidity to hit that venue. That behavior isn't what a reasonable person would expect by default.

There is no mention of things like flash orders (which no longer exist in US equities?), hide-not-slide, payment for order flow, maker/taker, etc, all of which are potentially problematic and deserve discussion.

In short these defences are nearly as simplistic as the attacks they attempt to counter.
>Here's a question though: what happens when the "whale" is really something like an index fund that, ultimately, is composed mostly of retail investors? Aren't they getting ripped off in that case?

Damn right they're getting ripped off.

The defense in the OP is essentially "yes, that can happen but it's very rare". Which is about as believable as it sounds.
I have learned Node.js from scratch over the last 6 months or so (I was introduced to it by the Startup Engineering MOOC on coursera). Before that my experience was with backend languages - C++, C#, python.

Initially it was a steep learning curve and coming from a "synchronous" way of writing code, I managed to get myself in all sorts of mess. But with time as I have become more comfortable, discovered new patterns (async, promises) I can say I am liking node.js more and more.

Also, the ability to code in a single language for your entire stack (Angular, node, mongo) is not to be overlooked for productivity gains.

So far I haven't really gotten the change to try Go but if your fears are just regarding the async patterns in node.js, I can assure that its NOT that bad and in return it makes you a better programmer.

I took 5 assembly-based courses. To make a compiler, all you have to know is assembly, but I took a compiler course, too. You don't need any theory courses to make a compiler, just assembly. If you know theory and you do not know assembly, you cannot make a compiler.

You think I lie? Can you make a compiler? No, right? I made a compiler. I tell the truth.

This should have implications for car batteries as well. Tesla is essentially a car running on very many laptop batteries.

Thus if you can charge a phone in 30 seconds. You can probably charge a car with distributed battery modules in similar speedy time frame.

This will mean pollution free cities in the long run, clean cars powered by Thorium reactors. Imagine mega cities without the car pollution.

Shorter time frame, your laptop should be able to fully recharge 50 watt hours in 300 seconds with this type of battery.
Exactly. There's so much work for people with those kinds of skills in the US and Europe that the "dialup daytrippers" end up in the corporate world right out of college. Even people who participate in illegal activities often have day jobs where they do white hat things.
I don't think that makes any sense, that article says
"Fastrak admitted that it was a mistake to transfer the ticket back to the former owner."

I am pretty confident that California law is advanced enough to handle the case of selling a car to someone. Carmax doesn't have anything new in that realm.

I actually think it's very inline with their thinking. Apple has always (since Jobs came back anyway) focused on being smart/choosy about their product lineup, but IMO they chase good design, not what's new. If the two happen to coincide with each other, great, but if not, design over something out of this world new. They were in the right place at the right time for the original iPhone, but I think that was an anomaly due to lazy competition. I think Nest had/has similar culture, and they were kind of a spin off from Apple anyway (designer of the iPod or something like that?). Thermometers are not new, but they managed to clean it up a bit (I'd like to see the same happen to receivers, why is the UI so terrible for them still).

I suspect their design values will preclude them from ever making a phablet, and that there is a line in the sand beyond which a device is too large, and at that point they will try to figure out an alternative solution rather than boosting physical phone size, but I don't think the current 5/5s screen size is at that line yet.
"Psychology is not bullshit like I used to think before."

Yes. I assume most HNers are "rational", logical, analytic thinkers that despise office politics and allowing feelings to clout "sound" decisions. However, feelings exist, office politics exist, and humans are irrational. Therefore, being logical and "rational" we have to account for these pesky "stupid" things and act accordingly if we want to maintain our logical and "rational" self labels.

I'd love a "Bookmark selected tabs" kind of function that lets me quickly click on a dozen or so relevant tabs. Usually, I'll have 20+ tabs open with 5-10 on a given subject, so "Bookmark All" captures a lot of useless tabs.

Better yet, a "Bookmark similar subject" plugin would be awesome - Leverage Google's search to automatically figure out tabs that are about the same thing and bookmark them by subject. Ignoring pinned tabs would be a bonus.
That 'android' that is killing is AOSP, not GMS, and the accompanying users are the least valuable to operators. Where the market is not saturated, any customer is a win, but in saturated markets, the competition is to skim premium customers out of the churn.

If anything this situation is likely to become more prevalent, not less so.
+1 for trolling/flaming (simply not enough of it left on the internet) but I dont agree. it's propoganda but I welcome this and all forms of ranting and propoganda. agitation can lead to discussion.

I think you misunderstand. After meeting someone and exchanging public key fingerprints, you verify their identity. This requires checking their government ID and making sure they really are who they say they are. Then, you verify the uid of their key by sending them a message encrypted with the figerprint you received in person. Only the holder of both that key and the email address can respond to your message. Then you can sign their public key and return it to them.

Comic Sans does serve one good purpose; it's a dyslexia-friendly typeface. It's nice that Comic Neue preserves some of the letter "hints" (ie. the "b" and "d" glyphs have slightly different bottom terminals).

Although if you're trying to optimize specifically for dyslexia, you'd be better off with something like OpenDyslexic [1].

Don't get me wrong, I agree with you. Even my personal 100% static content site is served over HTTPS only. I am just commenting on the pattern that any GPG-themed sites I've seen follow.
I'm willing to grant you that outlawing payday loans and similar predatory practices without consequently causing all sorts of nasty side effects is hard. But what you're saying amounts to "it's hard so let's just not bother at all" which is incredibly defeatist. Using that reasoning, why bother doing anything about anything at all?
Have you actually tried using a 5 inch phone? I think you may change your mind if you haven't. Trying to use someone's iPhone X after using my Nexus 5 is quite frankly laughable to say the least.
I think the best definition is in Fielding's thesis where he lists the 4 REST interface constraints: 1) Identification of resources 2) Manipulations through representations 3) Self-descriptive messages and 4) HATEOAS.

1 & 2 mean that you should name a resource something for identification only and that name should be used no matter what you are doing to it. In HTTP you use a combination of verbs and request body data to tell the server what to do with a resource. HTTP implements #3 though status codes including verbose descriptions in the response body. HATEOAS (Hypermedia as the engine of application state) means that 100% of functionality must be accessible through a browser.

I think this is a case of Apple's stubborness giving them a little bite in the ass. It took them a long time to come out with the iPad mini because they didn't believe in the inbetween tablet size, and now it's taken them far longer than it should've to come out with a bigger iPhone. Apple was late to the party with 4G as well.

I think once a bigger iPhone drops it will put a big gust of wind in their sails but I also think that Apple needs to be skating to where the puck will be if they want to keep their place as the premium manufacturer. If they're 2 or 3 years behind what Android (Samsung really) phones have the narrative that Samsung is more innovative is going to gain steam.

The other looming challenge for Apple is that software services are growing as a differentiator in phone ecosystems. Most of the Google services thoroughly outclass iCloud, meaning that iCloud doesn't give the Apple the competitive boost that it could.
>And if we move to a model where consumers pay for the full price of the phone (which is what much of the world does today)

It's coming pretty fast. AT&T is pushing Next pretty hard, which is essentially an interest-free repayment plan spread over 20 or 26 months. If you go to buy a phone now, that installment price is listed first, rather than the contract prices. You still don't see the "real" retail price, but you sure do see that an iPhone is $25 a month and a Moto X is $15 a month. (The Moto X is the cheapest current gen phone they have, I think. Something like a Nexus 5 would be even less but isn't on Next.)
The power of observation is not an attribute of the observed.

I tend to use comic or handwriting fonts for annotated screenshots when explaining visual or UI/UX things to people. It makes the distinction between the screenshot and my annotations sharper.

It is defined very clearly. The fact that most developers don't know what it is does not mean REST is a subjective style.
If you're buying a million dollars of Yelp (as posed in this hypothetical), then it's going to take some time (microseconds, minutes, months, etc) for people to realize that. For as long as no one catches on, the person making this large order has a tremendous advantage because supply-demand is misunderstood by everyone else. The market can't fairly price the stock as a result. The HFTs are saying they'll pay the money to get order info in nano-seconds so they can design algorithms to recognize these large orders and react appropriately. They make money being a middleman but the benefit for the rest of the market would be seeing a price change and also for small orders to be filled at a fairer price to supply-demand.
