Ask HN: The best answer you can give to "Why are you doing this startup"?
I am repeatedly asked "why you and why this startup?" when talking to people about what I'm doing. VCs and other startup experts always kick off with this question. I get through the answer but always feel "because it's an interesting problem" is what it boils down to.

What are the best answers given by entrepreneurs to the question: Why you and why this startup?

I agree with your points except to claify my point on compiler's correctness:

> issues stemming from undefined behavior documented as such in the C/C++ standards. So we're more focused on eliminating undefined behavior from the Rust language at the moment than proving the Rust implementation correct.

That's exactly the problem. Since C and C++ specifications have UB, compiler writers could anything they feel right.

When I say spec I mean the language specification itself. If we are on the same page on this, then yes, I agree that the spec should be proven correct. If not, please excuse my lack of knowledge in compiler and language construction.
I'm extremely ignorant, but I've enjoyed Brian Greene's books and I'm currently reading The Fabric of the Cosmos.

I've no idea how accurate it is or if I'm even understanding it. He could literally flip around the explanation and I'd have no way of verifying. Yet I still find it very satisfying to read.
The Architecture of Open Source Applications book[0] gives a high level overview on many open source projects. It's a good starting point to dive into the code of these projects.

Great... now they are going to get even harder to actually do.
Yes, you're right. Soylent = soya + lentil steaks in the book.
> a lot of people are seeing reduction in triglycerides or cholesterol

I suspect that the powder may be oat-based. Oats is a very nutritient-rich cereal, and does in fact lower cholesterol. It has high carbohydrate content, but it is also a rich source of minerals and proteins. See http://nutritiondata.self.com/facts/cereal-grains-and-pasta/...

If I were to mix my own "soylent", I'd base it on oat porridge, probably some protein supplements, some vitamin and mineral supplement, and a can of fatty fish. At probably a fraction of the soylent price.
I do prefer Racket macros to Template Haskell, but you can do some of the same kind of things in Template Haskell. Go ahead and play with it for it for a bit.

Mostly, you need to have the data-structure it defines for the parse tree, and it's harder to convert than syntax->datum. Also there's the Q monad, to generate new safe names. But it works pretty well.
When you say you receive classical information as the outcome of that experiment, what's an example situation in real life when you receive quantum information and do indeed get entangled with it (I mean if at all such a situation ever arises)?
This is why some IDEs allow you to to "peek" at a definition, for example.

Agreed! How have I lived without this...
Can't I? What if the state of these poor remaining neurons and the body is scanned, encoded as polarization of a bunch of photons and sent to a receiver far far away? In that case good old environment would definitely end up behind the cosmic horizon.
Really you'd want to send a few Hazda to live in Rome for a couple of months and send a few Italians the other way. It would be a good experiment - I'd watch the reality TV show.
I'm still searching for something a la tinc, but with a decent crypto story (tinc goes out of its way to say that it probably isn't safe).

SigmaVPN would look awesome, but lacks Windows support. I'd give ZeroTierOne a shot, but that lacks Android support. Any other solutions for a "VPN Of Things" if you will?
Agreed but if function follows form then Yii is somewhat lacking. Maybe I'm just biased because when I was in a tight spot digging through the source and docs didn't get me where I wanted to be.

Looking at their GitHub now I must admit that the source code and comments look pretty good.
Yeah... try to look up some category theory terms you found in the wild on Wikipedia. You will not be enlightened.

I guess this can be generalized to most mathematics on Wikipedia.
The number of lines of "Greeked" text should match the number of events you have for that day.

Random tidbit: among the Greeked text in the old calendar is the phrase "Hello from Seattle." It's a phrase that also occurs in several places on WP, including EXIF data in photos. It also occurs in various other MS products, if you know where to look :)

Unfortunately, MS has a policy against many easter eggs, like the flight sim in Excel, since the Trustworthy Computing Initiative: Undocumented behaviour is untested behaviour, and untested behaviour may lead to security and other issues. Easter eggs in MS products now are limited to such harmless ones.

Comparing Backbone and Angular is like comparing apples and dinner.

Backbone is a library. You can use it or ignore it, combine it with other stuff, you call Backbone code and use its objects, and it does some limited but well-defined stuff. It's easy to combine with other libraries, and you don't have to use Backbone's feature everywhere if you don't want to.

Angular, on the other hand, is a framework. It shapes everything you do. It bootstraps your application for you, and calls your code when it needs your input. It imposes a totally different way of working and thinking on you. What it does for you is far bigger than what Backbone does for you. It doesn't play nice with libraries that haven't been written for use with Angular.

Really, the difference is like writing a basic Java program where you write the main() and you call some libraries; and using a webframework that handles tons of stuff for you and you just write the controllers, services and views.

Confession of a Haskell Hacker (2012)
10 or 15 minutes?? Maybe if only one or two special cases apply to you, you know exactly in advance what you're going to do and have everything ready, but that's not a realistic scenario. Several hours of looking for documents and trying to understand what exactly you need, then probably waiting for days or weeks for some third-party documents to arrive, that's my experience.

And the large number and high fees of tax advisors in Germany would seem to support my view rather more than yours.
The event is neither in my causal past (it has no influence over the current state of my body) nor in my causal future (I have no influence on it). It's simply uncorrelated with me. If now you remind me of the number again, it becomes part of the causal past of my (new) body. Analogy: if a dwarf dies in a fortress far far away and you don't hear about it, her death is neither in your past nor in your future. You know nothing about her state: in QM, you would say that your brain and her are in an uncorrelated, product state, something like |dunno><dunno| x (|dead><dead| + |alive><alive|)/2 .
The x stands for \otimes, tensor product.

About popups/tooltips/hovercards: I considered this approach, but decided to go with this sort of "inline" expansion for the following reasons:

1. A popup obscures the original text. This interferes with context, albeit admittedly to a much lesser degree than full-blown navigation, but still.

2. Multi-level popup hierarchies just don't look good, in my opinion.

3. You must dismiss a popup to continue, whereas with inline expansion you can just as well keep the expansion and continue reading.

4. The hover approach doesn't work as well for touch-devices (i.e. without a mouse).
If one does not need technical support, one can use the open source edition on the desktop and on Android. On iOS one would need the commercial edition due to the restriction on dynamic libraries preventing the use of LGPL.

At least a couple of years ago it used to be around 2500 EUR / platform.
Then you have implemented teleportation and we have new problems to think about!
This is a nice start, but I already see one issue with this that the "Navigation popup" doesn't have: nothing on the hovercard is clickable, and thus you can't go more than one level down a tree.

The navigation popups are great except that if you move the mouse off them then they close, so as you traverse down the tree you lose parents. And you kinda end up with the same issue as before only now you really have no idea how you got there because you don't even have the open tabs to guide.[0]

there is a CVE, but i didn't see any CVE assignment happening on oss list.. who did the CVE assignment?
If you're talking to VC's, the answer that got us the money, was:

"We really felt there was an opportunity in the market for a well underwritten product. That could claim a sizable share of the userbase for (your app here) and we believe we can leverage that userbase in to a profitable business generating revenue (or EBITDA) of X by X"
Totally didn't know about this! Cheers for the heads up.
Thanks, that's a very good deal!
Super, this is exactly what I was wondering - whether they really had done something brand new or just put it into an app that lets you choose the blur point yourself after.

I think that's right, companies may have figured out that a decent percentage of people who have a valid right to make a claim against them will simply give up and go away when they see such a notice. Signs or a disclaimer in a contract are cheap to add and scale well.

An example many people are familiar with are parking lots which display signs with 'We accept no liability...' or similar language. I had my car parked at a hotel in a direct line of sight and close to the front desk and it was vandalised by two men attempting to steal it. They had the hood up, trying to defeat the security system and were trying to saw through the steering wheel to remove a 'Club' steering lock for over an hour while I slept. All of this plus bored front desk attendants on CCTV.

I woke up to find this in the morning and asked the hotel about it. They acknowledged seeing what happened and admitted doing nothing. This was a nice car at a luxury hotel, too!

I informed the manager they would be taking responsibility for the damage and he did the usual 'We aren't liable' nonsense. I sued in small claims court and won a judgement and collected. The hotel is probably still ahead of the game by denying others' claims, but I challenged this and won. I hope more people will try it too.

The second law is an empirical statement. This entanglement based approach is an attempt to understand the underlying physical mechanism that controls the spread of entropy. If this picture is right, the next question is what is the physical process behind entanglement.
If you are interested in creating your own Soylent, there's a dedicated subsection of the website[0] for sharing recipes.

Frankly, I doubt you could recreate, or equivalently replace, Soylent-the-product for as little money as it will cost to buy[1], but it's definitely possible to replicate Soylent-the-idea yourself. It's much easier if you don't intend to replace every meal with a Soylent-like, as you can substitute the harder-to-source ingredients with foods that already contain them.

My concern about Soylent has never been about the macronutrient ratios, nor the quantities of (comparatively) well-understood micronutrients like vitamins and minerals. The amounts of these substances seem relatively easy to get right, or at least within the range of "healthy" accepted by a consensus of mainstream nutritonal experts.

My concern is about the thousands or millions of micronutrients and phytonutrients that are poorly understood or even yet to be isolated by nutritional science, and the subtle and complex way they interact with our bodies and each other.

To me, the entire premise of Soylent is predicated on the idea that we know, on a compound-by-compound basis, what's good for our bodies nutritionally. The more I learn about the state of nutritional science, the less I believe this to be true.

Spine is even lighter than Backbone. I like Spine because its functionality is not really tied to the DOM or jQuery -- I make native mobile apps with Spine on Titanium, for instance. Spine is built out of components (i.e. Model and Router), which can be used separately or in concert. It's a massively underappreciated framework that has had staying power.

Not to mention, stepping through (or trying to log) the endless anonymous functions created by underscore can be a hassle and straight crashes chrome/node inspector in some situations.
"real life" as in "they can do it for real in a lab": Alice has two photons, applies a quantum operation to them so that they become entangled, and gives one to Bob. Bob received "quantum information" from Alice. They can use this resource (entanglement between the photons they own) to perform several tasks now, like "teleportation" of the state of a particle, or secure key distribution.
I'm not sure if I really want to eat the food of a brand that is that much afraid to be sued. Says a lot about the confidence they have in their products.
Same here. It's probably popular because it's new and it's an experiment challenging the concept of "Food", but apart from that there's no way I'd want to eat that stuff either. Actual food at home or outside is, as you say, one of life's pleasures.
The real WTF is that outright lying to the customer in such a manner is legal at all.
The most interesting things to read are those where a programmer has done something cleverly, but this only needs to happen when your language or libraries make it hard for you to begin with. Aside from low-level performance intensive functions, the best code is not interesting to read - it just reads like statements of fact.

Well Soylent is going to be an interesting test to confirm what we know and do not know about nutrition. As long as there are some willing volunteers to put their health at risk, I'd say why not. It will benefit mankind as a whole to know more.

I learned a lot from the Cocotron source:

https://code.google.com/p/cocotron/source/browse

It's a free cross-platform implementation of Apple's Cocoa, so there's a lot of stuff there. But the project is well organized, and almost everything is written in a minimalist oldschool Objective-C style.

I've looked at some other cross-platform frameworks, and they are often hard to understand because they have been developed by a large group of developers and include lots of complex optimizations and platform-specific code paths. Cocotron is not as finely tuned as Apple's CoreFoundation (for example), but much more readable.
It is interesting that this is open source and BSD licensed, so in theory RedisGreen could use the same stuff as well and join the effort. This is the common part of the infrastructure that makes somewhat sense to develop together.

Next, I chose the ones with the best documentation, example code, and active community. In this case it was scrapy (scrapy.org).

Last, I dove in. By the end of the day I had some code that was actually useful.
