I am happy to discuss these issues, but would rather have a fact based discussion than resort to insults.

Firstly, not sure what you think the distinction is between HFTs as opposed and "algorithimic market makers". I think most people would equate them, for instance most would agree that firms like Virtu Financial and Knight Capital Group are both HFT firms and market makers (for instance, they are Designated Market Makers on many NYSE securities, the closest thing we have to an "official" market maker these days).

Second, HFTs definitely make more money in moderate to high vol (the current period of prolonged low vol in the markets has been pretty hard for the sector), and during those periods it seems even you agree that they are providing liquidity - and I would argue, adding value.

During extreme vol events, yes HFTs will pull out of the market, but so does everybody else. If they can manage it, they will liquidate positions, but their books are small relative to other players, I am skeptical that this is an important factor in further increasing vol, will stand corrected if you can point to me evidence it is.

If HFT is really making vol worse, then why are we not seeing higher vol since it became prevalent? Certainly, we have had periods of great macro uncertainty in the last half a dozen years, but there was no apocalypse in the market.

Finally, my point in bringing up the NASDAQ broker example, is that HFTs perform an important function as market makers. If you want to get rid of HFT and do not propose who's going to take their place, I have to assume we would go back to the old system of human market makers. I think pointing out their flaws is entirely fair.

It's easy to demonize HFTs, but nobody forces you to trade with them. It would be relatively easy to setup a darkpool that does not allow HFTs to trade there. Some people have tried this (or at least to market the notion that they tried), but inevitably they decide they need HFT liquidity and end up courting them instead.
Agreed. cPanel hosting services make me want to vomit (bluehost/hostgator/etc). The thing that bothers me the most, is we often set up WordPress so someone can edit a few lines of text ever few months. Total overkill IMO.
I am going on a rant, but can we stop using the term lifestyle business for non-VC startups? Almost anything would be better - I came up with the term founder focused as an alternative [1], but almost anything would be better than the term lifestyle. A serious business is a serious business no matter the funding source.

The fourth option is working for a startup. How is that not getting a job?

Edit: to be clear: having done both I do agree it's a very different thing from working a boring job for a large company and I'm definitely hoping to keep working for startups for a while myself.
> We attribute intelligence to humans, most of which are barely able to parrot what they hear from each other. I don't see why being generous to animals is any kind of a problem...

Barely? Humans have an incredibly unique ability to constantly create new sentences, infinitely many of which can express the same idea. That is a unique facet of the human brain.

Being snide about humans doesn't make apes any more intelligent. They simply don't have the same linguistic capabilities.

Here's some other research data. In Guamtanamo they kept prisoners awake 11 days and found "surprisingly, little seem[s] to go wrong with the subjects physically." In rat experiments they all died by 32 days. I'm guessing full sleep depravation in humans would have a similar result to rats though thankfully no one seems to have tried that.

Two production lines? For what?

I agree with this one. It probably wouldn't be terribly expensive to implement, though I would question the priorities of anyone who is really hung up about it (like the grandparent post who started this whole discussion).

Interesting. I can sleep just fine on modafinil, but I still have greatly increased focus if I just choose to stay awake. Also, I've never noticed any increase in tolerance (which I get very quickly with caffeine and alcohol), even taking it every day for two weeks, although maybe that's not very long.

I'd love to see an evolved C that targets the most performance-obsessed programmers. Features like:

* fine-grained control over alignment

* automatic generation of SoA code from AoS code

* first-class SIMD types

* pragmas to switch the compiler into branch-avoiding codegen

* cache line size as a built-in constant, with ability to compile a binary that contains several versions of the complete program optimized for different cache line sizes

* user-defined calling conventions

* vectors, matrices, and quaternions (taking care of 90% of the cases where you really want operator overloading in C++)

* ability to treat an integer as an array of bits, bytes, or smaller integers, a la Terry Davis's "Holy C"

And the standard library could contain some nice performance-oriented stuff like:

* portable memory allocator that exposes pages, virtual memory indirection, reserve vs. commit, etc.

* fixed-point math

* approximate transcendental functions

* bitwise stuff a la the "Stanford Bit Twiddling Hacks"

while also adding modules and cleaning up declarations like C2 does.

I think a lot of programmers would like it.
this is so crazy. congrats
True, but isn't the whole point of an alarm system to draw attention to the thieves? If a thief can bypass the alarm system or other security measures, it may not look they are stealing the car. This gives them a significant amount of time before law enforcement can be informed and greatly lessens the chance of them being caught.

This is beyond fantasy.

Nearly everyone in America has a smart phone in their pocket more powerful than the most powerful computers of just a few years ago. On that device is all of worlds information, a Google search away. What do people mostly do with this access and power - nothing - Facebook, Reddit, and other distractions. Giving people handouts will not lead to an revolution of art, culture, and businesses... It will lead to sloth, resentment, and failure.

Our society already produces enough abundance and opportunity such that any hardworking individual can EARN a life that most people in history could only dream about.

A bootstrapped business does not have to be exclusive with larger revenue streams.

Guy Kawasaki says that he's seen many more businesses die because they tried growing too fast (e.g. using VC money to scale the company) than because they grew too slow.

Joel Spolsky is famously a critic of the SV VC-based model as well. He put his money where his mouth is with Stack Exchange, which only recently raised VC money. He says the obvious, that if take things as far as you can without VC money, then you get better terms when/if you finally do take it.

There are a bunch of companies, especially those with strong network effects like social companies, that face a very real risk of growing too slow. There are others, especially hardware companies, where the startup costs are high. So the bootstrapped model is definitely not for everyone!

I think it's best to stay small and agile until you've found a strong product-market-fit that can the company can be scaled up into. You may or may not need VC money during that stage. When your biggest problem is you lack the resources to scale up as fast as your real product demand, then you should be looking for VC money (or a alternative financing like a loan.) Before then it may well do you more harm than good.
tl;dr: owning a business does funny things to people. Make sure you're one of the ones who can handle it in a healthy manner.

Reality is having a couple million a year business can really lead to a fantastic lifestyle if done properly.

Emphasis on the "if done properly." I know a man who own his own american manufacturing company (yes, they still exist). They specialize in electric motors. They do good business despite having fewer than 50 employees and gross about $5M a year. I'm not sure how much of that is profit, but I'm going to guess most of it. The owner is fanatic about keeping costs down.

On the other hand, he doesn't have the temperament for business. He's a ball of stress all the time. He's always getting angry over what many here would consider standard business practices. He micromanages his company, especially his IT staff (which is one guy). He's had 4 heart attacks in the past 10 years. He has fewer than 50 employees because he refuses to pass the minimum to qualify for Obamacare (which would raise his costs considerably). He's a good guy, normally, but business ownership has been a net negative on his health and mental status.

I knew one other small business owner that was similar. He owned a successful comic book store at the local mall. He did great business and made a lot of money. Then, about 6 month after he opened the store, he noticed that shoplifting was increasing. He then became obsessed about limiting his losses. The idea that somebody could easily steal his merchandise stressed him out beyond measure. Business started going down around then because the changes he made to limit shoplifting also limited his exposure to passers by and made the storefront look unwelcoming. He eventually moved the store to the first floor of a single family home just outside of the city limits. His profits dropped considerably, but so did his losses. His stress also went away; he was no longer worried or obsessed about it. The tradeoff was worth it to him; he literally traded high profit for low stress.
Only factory farming of animals is on there, and given the suffering of the animals involved I think it's a complete no-brainer that it overall does harm.

Hey HN!

This is yet another HTTP proxy written in Go so I'll try to be brief. :)

Martian was written to provide a solution for writing larger E2E tests that require custom behavior at the request/response layer.

For example, we've used it to spoof headers, redirect traffic to local fakes, and verify that all traffic coming to the backends is over HTTPS.

We wrote Martian so that others could build their own proxies to suit their own needs. Martian provides a Go API[0] for building custom behavior and a JSON API[1] that can be used to reconfigure the proxy at runtime. We provide a fair bit of custom modification and verification behavior out-of-the-box, such as header modification[2], URL verification[3], and filtering based on proxy credentials[4][5].

Check out the README and if it seems interesting feel free to ask questions or let us know what you think. :)

An example proxy binary is available in the examples directory[6] and can be run with `go run`. Note that it requires Go 1.5 due to some recent changes in crypto/tls we depend on for dynamically generating certs.

> "learns nothing, make no progress"

1. What makes you so sure you learn nothing during sleep? All the articles I've read about sleep's role in learning have indicated that it helps us process what we pick up during the day.

2. Why is 'progress' so important? Progress towards what? What are we chasing after?

Whilst I realise you were only questioning sleep from the point of view of its utility, for me utility alone kind of misses the point. For me the rituals around sleep are some of the best parts of daily life. I love drifting off to sleep, I love dreaming (when I'm lucky enough to remember it at least), I love waking up without any great urgency, slowly coming to my senses, wrapped in the warmth of a comfortable bed. Whilst I appreciate it wasn't your intention, I dislike the notion that our time must be spent on making ourselves better people, if we aren't causing great harm isn't enjoying what we do reason enough to do it?

Which has nothing to do with them being intelligent or not.

It would be awesome to see aliens land here with blatantly superior technology, but they have no linguistics at all. Finally everyone would stop thinking you can't have intelligence without linguistics.

And to promote an even heterodoxer opinion, learning Deeplearning4j might be an even better use because Java is the language of corporate IT, the language of Hadoop (and therefore big data), and because Spark is based on the JVM. If budding data scientists want their neural networks to scale, they should think about distributed systems from day 1. http://deeplearning4j.org

Full disclosure: I helped create DL4J, and it is a younger framework than both Theano and Torch.

The main issue would be fixing the problem of pointers; high-performance code is hard to write in C because of pointer aliasing. Rust has an interesting approach in its ownership model but I think a performance-oriented C evolution would require another more general solution.

I love static websites. Most of our YC websites are static (www, startupschool, femalefounders, fellowship, etc.) Problem is I'm not sure we've really seem any great innovation here in regards to nontechnical adoption since MovableType. I know we have Jekyll and Middleman and those are fantastic pieces of software for developers (we use Middleman here at YC), but they're missing a UI bridge to get people to the promise land.

Your current implementation...I'm not so sure it can reach nontechnical people yet. I think it sits at this middle point that makes it easy for technical people to hand off content management to nontechnical people. That's probably a good / smart way to start...but it will limit your potential audience.

Looking at the site, I don't think targeting a technology is the best approach. People aren't going to be Googling "alternatives to cpanel" to try and find you. You should be targeting people / use cases. Designers, creative agencies, IT people dealing with the marketing team, etc.

The zip a folder and upload is a great interface (A+ on giving me a sample project to try), but what I'm most interested in is how the CMS / form stuff is going to work. Unfortunately, it wasn't ready yet. I will say that adding classname is a good start, but remember try to build features in a way that it doesn't require people to edit code. Find some way to allow people to click to specify what'll be dynamic. It could use the same mechanism, just make adding the classname a thing that's done with a click and not a cursor.

The CMS / Form stuff is what's really going to sell this into organizations. Then you're going after a very large space. I think something like 45% of the Internet is powered by a CMS. 25% of that by Wordpress, something initially made for some other task. If someone gets it right, there's a lot of money to be made.

Thanks for sharing and I'll be on the look out for your fellowship application!

Or, rather, in some parts of the world, the negative connotations (not actual a change in meaning) it developed in some places from popular association with the German use of the term hasn't caught on, so there is no perceived need to replace it with a new word with the same denotation that "propaganda" has had for centuries.
