Sure, you won't get much of a discount from anyone for quantities of a few hundred. You might be looking at a 2x price difference, which is pocket change for a few hundred machines. In quantities of hundreds of thousands or millions, the price difference is well over an order of magnitude because Solarflare won't play ball the same way other vendors will.

That adds up to a significant number, even if it's "only" 10%-20% per server, and you're probably overestimating the cost of the rest of the server since large companies are able to get steep discounts on almost everything in the quantities they buy in.

> Mellanox etc. tested similar but had less helpful sales engineers

We've found Mellanox engineers to be more helpful than Solarflare folks. I don't think that's because one company has inherently more helpful engineers. We're just not in a market that Solarflare cares about and you're not in a market that Mellanox cares about.

> if you actually care about latency, you do not use windows nor use the public cloud

You might be surprised by how many HPC shops have moved from fancy in-house infiniband networks and custom fabric to cloud hosted HPC clusters. HFT isn't moving to the public cloud anytime soon, but a number of large customers who care about sub-microsecond network latency have found real value in moving to the public cloud.

I have not used flux. It's not difficult to understand Redux, but the setup is not simple. Defining the constants, defining the actions, then defining the reducers. It's a lot of moving parts. Throw in the connection to react via react-redux, and it feels like you've had to repeat yourself in several places, not exactly, but enough to be annoying.

There might be ways to speed up the running time for this special case. Naive algorithm using submodular minization + maximum matching as an oracle would take around O(n^c) where c is probably more than 10.
Yeah, Radix can get a bit memory hungry if you don't pick a small enough k(although you trade that for more passes through the data).

That sounds like not much of a benchmark to me. Did he have any reasoning behind it?

Yeah, I remember when it used to be a joke that C++'s type system would become turing complete before it got reflection. I don't know if it's more funny or less funny now that it's actually happened.

In any case, that's what the "in the wild" constraint is for. The name length limits imposed by the ecosystem probably aren't as interesting as the creatures you can find swimming in its depths. Probably.
In that same respect, you're paying for that same shipping when you buy from a brick and mortar store. Whatever overhead it cost to get the item from point A to point B, you'll end up paying for somehow.

From the article:

> All this should be a reminder that any trade deal has winners and losers and unintended consequences.

Obviously, whoever you subsidize is a winner. If you're setting up barriers to trade (e.g. tariffs), foreign sellers/manufacturers lose. If you're subsidizing imports, domestic sellers/manufacturers lose.

Why can't we just not subsidize anyone?! Free trade is supposed to be just that, free. Instead, we have the TPP & TTIP, which will create yet new injustices and new sets of winners and losers.
I don't understand these sorts of proposals: what are you insuring?
Of course there are subsidies and complex discount + partnership relations involved, but in the end the question is simply: WHO is paying for this?
Thanks for answering. The point you're bringing up -- the value of being able to function in a world among people with a wide variety of beliefs that conflict with yours when you have no choice and not much power to effect change -- is totally valid. I thought you were extrapolating from that to argue that we shouldn't take action when we can. In the case of Eich, the power happened to be social pressure, and it was used to oust him. I'm not crazy about the tactics, and such tactics can be abused, but the result in this case is that it's now known that at Mozilla, at least, homophobia isn't tolerated. I thought you were arguing against that result on the grounds that people should have had more "tolerance for diversity of thought," namely the thought that gay people shoudn't have full marriage equality, with a political action to support it. My entire response was based on that premise. If it was a misreading of your intent, I apologize.

That isn't how probability works though. You have a Bayesian priors problem - you can't establish what the initial probabilities are.
It depends on how "even" you think that 3% is distributed. If you believe that 90% of teams that apply have a 0.0001% chance, 10% have a 30-ish% chance, and you have good reason to think you're in the 10% case, probably.

I don't know if that's the exact math, but it's probably a lot closer to that than to evenly distributed.

I found it to be quite like the other way around. I thought React is a quite decent view library (with medium complexity, if you try to understand and use all the lifecycle methods and think about suitable keys for reconciliation), but I found Redux a bit too primitive for my taste and decided against using it. Reasons where that I don't think storing all state in a single object is a good design idea and that state for me is not only about serializable objects (e.g. I often need to keep promises and other stuff around). I understand that it enables some things like hot reloading and time travel debugging, but thats not the highest priority on my nice-to-have list.

After experimenting with React I'm now using angular2 for my project and apart from some bugs that are left I'm quite happy with it. Architecture-wise I put all state (serializable or not) in multiple-independent plain JS service objects which are injected into the view components through ng2 dependency injection. And they expose their state through observables, which together with things like async pipes makes reactivity really easy.
Can you give some details about how things blow up in complexity? I've not built a complex app in React yet, so I'm looking for things to watch out for.

Bear in mind I am asking this question as someone who has no experience in Scala/Play but is looking to learn some new languages/frameworks:

In the absence of ads-that-are-obviously-ads don't you think that clever marketers would just migrate to native ads disguised as content? There's something to be said for a clear line of separation between ads and content. It seems naive to think that the concept of ''advertising'' would ever be eliminated full stop, given how human nature works.

"Now if we want to apply to YC post-pivot, we get penalized? That seems incredibly unfair."

I don't think that's what is being said. You say YC would not have accepted you in 2013 - what you would want to do now is be accepted in 2016 as a company years further down the road. Is the bar higher? Sure, but that's natural. Demonstrate that you've made good use of those 2 years and you are in good shape to proceed and you should be fine, is what I read into it.
You're making sure that when the gun is handled negligently and shoots someone (i.e. when you didn't realize it was loaded, or when you mistook your neighbor or child for a burglar, or whatever), that the financial consequence is covered.

I 100% agree with that message, but I didn't feel your post conveyed that. My impressions of the post was a broad painting that all other accelerators are bad, even though I know that's not your intent.

I think a lesser emphasis on getting into YC and making the post more of "how to judge an accelerator" would have been better.
I hope you don't really mean "replace" ads.

The ad-supported Internet is one of the few places where wealthy people and poor people are on equal footing, where children can still explore without parental permission, and adults can explore without constantly asking themselves "is this worth it?".

I imagine micropayments will be exactly the sort of problem people decry in Facebook's Free Basics, where large companies can afford to give access to their sites for free, while small website operators are forced to live in their walled garden or charge micropayments (and fade into obscurity).

I also think it's kind of weird how many people like the idea of micropayments for websites when we've seen firsthand what it did to gaming, and especially mobile gaming.

I too am hopeful for a better system that can replace advertising, but I don't think micropayments are that system.

>I live in one of those "Record Warmest" boxes, it really was hot during the past year.

You can sense a 0.23 degree F average temperature difference? Or maybe you are unhelpfully confusing weather with climate?
Solar radiation is variable but it's pretty predictable. There's an 11-year sunspot cycle that accounts for most of that variation. https://en.wikipedia.org/wiki/Solar_cycle

Oceans so far have been storing heat, and keeping the average temperature increase down. No one knows how long that will continue. They also store a fair bit of CO2 which has lead to acidification. https://en.wikipedia.org/wiki/Ocean_acidification

I think this Ars Technica article does a better job of showing how short-term weather patterns like El Niño and La Niña cause variations from the overall trend https://arstechnica.com/science/2016/01/2015-was-official-th...
I second that. Any real climatologists on HN?
Well, essentially they're doing to YC what accelerators have been doing to venture capital. This is not 100% comparable but it is kind of logical that with a successful program like YC that there would spring up an industry trying to make bank on becoming a pipeline into that successful program.

The better way to deal with that would be to say that you want to emphasize simply that your chances are decreased if the previous investors / accelerator / your mom made your company less interesting and / or term wise unpalatable.

You might even go into detail about the kinds of terms and the kinds of advice that you feel are particular reasons to not be accepted, this might save a lot of founders a lot of grief, even the ones that did not decide to apply to YC because it comes from a respected voice in the industry rather than from some cornered cash strapped founder during the negotiations with a party much more savvy and powerful.
> When Microsoft donates X amount of what ever to some one no one pays MSFT that money back, they might get some tax relief for it that's all

I am not sure you understand how accounting works. You have a tax liability. Now, you donate a million dollars (let's assume money for the sake of simplicity). How is this donation reflected in your balance sheet? Well, your bank owes you a million dollars less, and at the same time, you owe the state 250000 dollars (or whatever it is) less. Now, if the fact that your bank owes you a million dollars less means that you paid the donation, then the fact that you owe the state 250000 dollars less also means that the state has paid you a quarter of a million dollars of your donation back. Or in other words: That part of the donation is paid for by other tax payers.

> It doesn't affect the price of the service in any way regardless of what portion of the global XAAS market or MSFT's own XAAS business it is.

You have it all backwards. This is not about whether the donation changes the price in other sales of the same service. This is about how you determine what the price of a product is. You determine the price by figuring out what people are paying for the product. Now, when you do this, you simply discard one giant transaction that happens in this market, for no good reason. This giant transaction happens to be one where the price is zero.

> This holds true even if you build your infrastructure and platform in house it's not like MSFT can donate universal credits

(a) How does that change the fact that it's not a commodity?

(b) Actually, they could. People commonly call this "universal credit" "money".

> You don't value the price of donated food at the local homeless soup kitchen by how much you could sell it to some one on the street you value it based on how much you will have to pay to make it on your own. And the people who actually receive the food tend to value it based on how hungry they are....

Which should all result in the same value, unless you are making a mistake.
4) is the biggest, yes. 3) does vary a bit ("Maunder minimum"). 2) is the other way round - the oceans are a big stabiliser of temperature.

A subtlety of (4) is the feedback loops, especially involving water. Water vapor increases heat retention and is increased by heat, but this is where weather interacts with climate and it gets non-linear.

> Denver to Salt Lake City is going to be really goddamn hard (mountains)

There's already a traditional railway that connects the two cities. The mountains have a bunch of passes through them.

The reason everyone flies is because it takes 15 hours and costs $81 one way per Amtrak on the California Zephyr.

Relative to a one way plane ticket with Delta which costs $157 and takes 1.5 hours. And while a $76 saving is pretty nice, is a whole day of extra travel worth $76 for you?

If you worked federal minimum wage (7.25/hour) you'd pay off the difference in only 10 hours leaving you 3.5 hours to spare... So it really doesn't make cost effective sense to take the train, only if you enjoy trains/scenery.
I don't like SQL. I think there could be a worthy successor to it. Something functional, typed, Haskell-like. Something that can incorporate other data processing paradigms, such as ETL, stream processing, map reduce and so on.

"The patterns of thinking that we take for granted around iteration and prototyping were still too alien. You have to get it before you can do it, and the types of programmers who were inclined to get it weren't in decision-making positions."

Maybe I was too harsh on them. It does seem likely. Further, it probably came directly out of the nature of programming on expensive, shared, and often batched machines. Here's a great example of what programming looked like in the 60's (skip to 5:27):

https://vimeo.com/132192250

It wouldn't have been much better a bit after 1970 where many of the same concerns and processes would exist. I still think one has to ignore most of the Royce's paper to not pick up on iteration paradigm. But, I could easily see someone in that mentality sort of glossing over it, spotting a diagram of their current flow, giving it a name, and pushing it from there.

Finally read the paper you gave me. It was really neat to see iterative development kept getting independently invented from the 60's onward. It getting into the mainstream was an inevitability due to its inherent advantages. The majority just couldn't contain it within limited groups forever.

"and found out that what they had really done was write code first, secretly, and then write up the requirements and design docs based on what they had learned. In other words they did things in the 'wrong' order but published them in the 'right' order."

That's funny you say that: history is repeating in high-assurance field. Safety-critical design is like waterfall or spiral on steroids with specs, constraints on implementation, rigorous testing, analysis... you name it. To outsiders, it seems they're using a waterfall-like refinement strategy to build these things. Insiders trying to get Agile methods in there have countered that with an unusual supporting argument: successful projects already use an iterative process combining top-down and ground-up work that results in a linked, waterfall-like chain of deliverables. The actual work is often done differently, though, so why not allow that kind of development in the first place?

With your comment, I've heard that twice. Another quick one was Mills' people not being able to run their own code in Cleanroom. Sometimes it wasn't necessary but it has many benefits. So, of course they often ran their own code during prototyping phase to get an idea of how the final submission should be done. We'll all be better off when management lets their processes reflect the realities of development. At least it's already happening in some firms and spreading. :)
It's non-zero, but essentially right next to zero, the number of people buying Macs who do not at all run OS X. So yes, it's bought as a whole, people want the product experience, the integration of hardware and software. That's why they buy it. If they really didn't care about OS X, or really didn't care (a lot) about industrial design they'd buy something else. And on industrial design, Dell's XPS 13 is neck and neck (bit better in some spots and not as good in others) with the Air.
There are hundreds of accelerators with more appearing all of the time (plus significant management turnover in many of the programs). Evaluating them all would be a full-time job for several people. I'd rather put that effort into finding more ways to help more startups.

Interestingly, Lisp tends to be more closely related to modern imperative or OOP languages than modern FP languages most of the time (although this is very much a matter of dialect, as Clojure and Scheme code tend to resemble FP much more than CL and Elisp code do). Lisp had some ideas influential to FP that also made their way into other types of programming (garbage collection, closures, etc.), but things which are considered a modern necessity for functional programming are not present in most dialects of Lisp (like immutability of data, at least by default, currying, etc.). In fact, most Lisp dialects don't even have first-class functions (in the sense that variables and functions are stored in totally different namespaces), which even languages like C# support. So to call Lisp 'functional' is a bit of a stretch, despite the large divides between different dialects and the multi-paradigm abilities of those languages, but that's not to say that it wasn't hugely instrumental in the onset of functional programming.
You are counting incorrectly. Xcode 6 and Swift were introduced at the same time. The point is that you can't count 6 because its feature set was already finalized once Swift was announced.
