Certainly Reddit is quite different but I can see a shift maybe among older users or maybe more of a dual membership.

Although Digg isn't actually speeding up their page serving, you should note that page speed is one of the cornerstones of conversion rate optimization.

Google will even penalize slower sites in SEO rankings. Page speed is about the easiest way to improve engagement and conversion rate with modern CDNs etc:

Well...Apple stock could do well.
For languages that support it, use lambda functions judiciously - too much of them make code really error-prone and hard to debug. (Not the most wide-spread problem, but came across this today)

Also check for null!!! ;)
It seems to me that the most common errors in C/C++ are memory leak and/or corruption issues. Coming from someone who's background is in managed/garbage collected languages, doesn't using a managed language help to avoid these common mistakes?

I know that it's still possible to leak memory in C#, like not releasing event handlers, but it's very difficult, if not impossible, to corrupt memory without using unsafe code. In those cases you're probably more likely to be careful with how memory is used or manipulated anyway to avoid causing corruption with the managed code.
On that note, I have been meaning to ask HN (even if nothing more than an exercise)...

If you had to run a site like Reddit, what would you do?
It's unrealistic and will never happen.

The market, overtime, always comes back to its natural state. Which is, 'Survival of The Biggest'.
Rustock botnet mysteriously goes dark
Bleh. I wish the system wasn't so broken. A straight up metered usage billing system would be fine, as long as the pricing was fair (which for some reason no company can get it in their head to try). With that sort of system there's then no reason to charge extra or to try to inhibit tethering.

Well, at this point, perhaps it needed to be said.

Reddit isn't vital to anyone's well being, but it is a service that hundreds of thousands (?) use pretty regularly, so it certainly isn't trivial either.

How is he hurting the situation by calling out a service for what it really is?

I don't know why in the US they prohibit honey.

Because unpasteurized honey can contain botulism spores. It's a small enough quantity not to bother an older stomach, but infants can die from it. I guess pasteurized honey is safe, but doesn't taste very good.

My question is: why in the world would you give a newborn infant honey? I can't imagine the logic that says, "hey, a baby just popped out of a vagina, let's get some honey into that sucker, stat!"
hmm, apart from ttl, you can use other tcp fields e.g. windows, tcp-options, packet-length etc. then, from a captured trace run passive os fingerprinting to find out with reasonable certainty the device generating the traffic.

these can/may be manipulated via ip-tables, but then you still have a huge data-volume to account for...
I think Wayne's story is intriguing and can give valuable insight into the reasons behind his actions before and after partnering with Steve2.

He also seems humble and honest with himself and to others, despite the obvious hindsight. He lived with his decision and went on to pursue his real interests without jeopardizing the interests of others.

To me he possesses qualities that should not be ignored. His character seems very strong and not motived purely by profit.

I'm quite sure he would be right here on HN hacking on ideas and building companies like the rest of us.
Tool or Toy? The iPad 2 for Photographers
I know it's not exactly in vogue these days to tout the merits of bare hardware, but.. after all the VPS hubbub over the last couple of years, the best progression for your website still seems to be:

1. No traction? Just put it anywhere, 'cause frankly, it doesn't matter. Cheapest reputable VPS possible. Let's say, Linode.

2. Scaling out, high concurrency and rapid growth? DEDICATED hardware from a QUALITY service provider--use rackspace, softlayer et al. Have them rack the servers for you and you'll still get ~3 hour turnarounds on new server orders. That's plenty fast for most kinds of growth. No inventory to deal with, and with deployment automation you're really not doing much "sysadmin-y" work or requiring full timers that know what Cisco switch to buy.

3. Technology megacorp, top-100 site? Staff up on hardcore net admin and sysadmin types, colocate first, and eventually, take control of/design the entire datacenter.

I simply don't understand why so many of these high-traffic services continue to rely on VPSes for phase 2 instead of managed or unmanaged dedicated hosting. The price/concurrent user is competitive or cheaper for bare metal. Most critically, it's insanely hard to predictably scale out database systems with high write loads when you have unpredictable virtualized (or even networked) I/O performance on your nodes.
Chrome and IE run on systems with faster processors and Gigabytes of RAM. RAM, especially is tight on iOS devices.

I also guess that some iOS apps will want to overlay stuff on their web views, postprocess the data, register callbacks, etc. Supporting such use might be a bit of work that Apple hasn't done yet.
Maybe true, but still not much consolation for the embedded systems programmers or maintainers of legacy code.
You won't get any better with that. Even if MD5 was a true source of randomness, the problem is still that you've only got 32 bits, so you'd expect a collision after 2^16 with a random function.

Besides, xoring the other bits does nothing to increase the security on non-broken hashing functions. Take the extreme case of xoring every bit to generate either a 0 or a 1. You've put a lot of effort into generating that single bit, but it's no more random than if you just took the lsb of the hash.
For those of us who are not familiar with the term liquefaction. In simple terms, I think it means the soil becomes like quick sand because of the earthquake.

...I was wondering if I was going to be the only one that caught that.

There's not enough information to know if that's even possible or not, or how it might be possible, but as far as I know there aren't any known postgres issues that would cause that.

I would be extremely reluctant to store data on a network that sometimes didn't actually store the data without raising an error anywhere.

Awesome. We'll see you there! Today I realized that we picked an Irish bar and its kinda close to St Patrick's day. Hopefully it's not too crowded/annoying. If so we'll think up a plan B and turn it into a bar crawl.
Does "I told you so" ever work in any situation? It only ever makes people mad. Unfortunately being right can't be pointed out in many situations.
sure, and the average man on the street may prefer that he become a multi-millionaire within a year. However, that sort of preference isn't as important as the realistic outcomes that a VC aims for.

Unfortunately, I don't have specific data to back this up, but my sense is that very few VCs get to invest in blockbuster hits like Google (and as I mentioned, Google didn't take VC investment until they had already developed great technology and a great monetization strategy. So investment in Google was at a much higher valuation than what you'd expect for the typical VC deal)

Again without specific data, my sense is that most money-making deals (for investors) are deals like the YouTube acquisition or other much smaller acquisitions ........ and I also think that most VC-funded companies make little or no money for the investors (and either crash or go through firesales).
I still dont understand.

They've made JS in Safari faster than JS in native apps.

If anything that would encourage people to dump the native app completely and write a pure web app.

> Google developed great technology and a great monetization strategy before they took in vc funding.

Larry/Sergey took $100k investment from Andy Bechtolsheim before they even had incorporated. Less than a year later they took $25 million in VC. AdWords was launched a while after that.
Are people using RVM in production? (like on a VPS) If so, how is that setup?
He was until recently, but a new investor took the spot.
reddit actually is a top 100 site, but we don't have nearly the need to host our own datacenter or co-locate. If we do make a move, it will be to #2. I don't want to hire people to be hands on -- I'd rather outsource that and let someone else pay to have spare capacity laying around.
It seems like a self-selection effect. We hear about the ones buying PR and pumping up their value. Those that are organically growing value don't need fertilizer.
It's interesting how great a baring the quality of the question has on the quality of the answer. Good questions get (usually) good answers. I regularly get caught in the crossfire resulting from poor questions resulting on poor answers.
I'm always surprised that phone companies in America can get away with charging extra for how you use your mobile's internet access as opposed to how much or what you use it for.

Seems like such a false boundary to segment the market on.
This video takes me all the way back to 1995, when I actually got Internet Explorer 1.0 with the Windows95 Plus! Pack.

Internet Explorer 1.0 through Internet Explorer 4 were during the Browser Wars. Internet Explorer 4 came with Windows 98, so after that the war was over since most people just started using Internet Explorer because it came with Windows and was the default browser.

Innovation often simply requires more investment (in both human and financial capital) than what a few-man show can handle.

With only lifestyle business you'd also exclude everything that has negative cash flow in the initial stages - except if you think another lifestyler can run a VC without relying on "the market".

Seriously, there are a lot of things wrong in our society, but scalable businesses ain't one of them.
Also, sometimes you might know someone who would be the best co-founder, but they just aren't in a position to be a co- founder (family, other commitments etc). But, you can still have them assist as mentors. I think a strong single founder with a good group of mentors could be as good as 2 founders.
Also, at a later stage, that mentor might find themselves in a position to join the venture.
Product idea?
The point of the article isn't that he isn't engaging online; it is that he is doing it on another platform (Twitter).
Maybe not quite that persistent, but I've definitely tried to sell investors on startups that didn't end up doing very well. Even by the end of the 3 months we are far from perfect at predicting who the big winners will be.
Practice. Fire up Photoshop, and paste in a bunch of designs that are well done. Start picking out individual elements, and then recreate them from scratch. You'll constantly be asking yourself why your redesign comes short, and through this, you'll begin to understand the subtle differences that make a great design.

I've never read a book on web design in my life, and I've kicked out some award winning layouts. The trick, don't stop refining the design, and don't be afraid to take a step back. The only time the design stops improving is when you stop working on it. Continue to refine, and you'll look back tomorrow, and laugh at the layout you once thought was acceptable. Fast forward another day, and you'll do the same. Have patience. Although great designs might look simple, realize they've gone through an endless number of revisions to reach that point.

Ok so make sure you build it mobile from the beginning. I mean delegate any task which requires to be in a specific place or to be online at a specific time. Or, worse, to be in a specific place at a specific time.

As a general rule this is true. However in my experience there is a segment of this market in the US that is extremely lucrative; essentially the top X% of public high schools. These schools are private for all intents and purposes, as most of their budget comes from property taxes. These schools have massive budgets that approach $100 million, extraordinarily qualified and perceptive teachers, and a community that is heavily vested (and almost neurotic) in the success of the students. Also, the staff at these schools are surprisingly tech savvy, often with a large dedicated budget for technology.

All the above factors combine to create a perfect storm for a business with an innovative product. If you've got a product that will make students at these schools more competitive in the college admissions process, it will be purchased at a massive price tag. All the key players, the parents, the teachers, and the administrators, have the will and the budget to make these types of acquisitions.

Note, marketing to these schools is difficult. A connection in the administration or the education space is the easiest way, but I'm convinced you could bootstrap yourself through the teachers. They are smart and savvy and the senior teachers can have surprising influence. Further, the market is on your side. One you convert a few of the top schools in the area, it is likely most of the other top schools will follow, as not to be left behind. Top schools will follow the leader, as these things go.

Overlook this market segment at your own peril. :) There's only a (relatively) small set of schools that fit the above criteria, but they have a combined budget of billions nation wide.

You may note that I did not mention the top %X of private schools. That is because in my experience, parents (one of the key players) aren't necessarily as invested in the school on a day to day basis. There seems to be a higher rate of apathy with parents in top private schools, whether as a result of geographic separation or some other factor. The bottom line is that at top public schools, the parents made the effort to move to the community, buy a house at a ridiculous value, pay outrageous property taxes. In practice that seems to create a much more invested base of parents that will be much more involved in the school. I still think you can sell to top %X private schools, but it seems harder in my mind.

If someone is thinking about starting a product in this space, happy to chat via email.

It makes it easier to offer unlimited data if you can ban all the ways of using lots of bandwidth.
"Survival of the fittest", you mean. There are plenty examples of big companies that failed (or would have failed wasn't it for government intervention).
Fair enough; 100 was sort of arbitrary, but there is some metric when you're sort of at google scale and cutting down on power costs or achieving absolute minimum latencies between datacenters has a meaningful impact on the bottom line. Draw a line somewhere, and yeah, Reddit is probably on the other side.
I strongly agree with this as well - however, when I need to overhaul a huge portion of the codebase, I may end up normalizing tabs and spacing somewhat; e.g. tabs between 'if', 'while', 'for' and '(', spaces between function / array name and '(' or '[', etc.

That is to say, I don't mind everyone being free to format code how they see fit, just don't be surprised if in rewriting or modifying it, it gets "fixed" differently.

I'm currently doing this right now at work, hence my vehemence. There's even things like this in class definitions:

int const * const	FooBar // Yes, that's a tab
(Foo foo, Bar bar)

which at first glance can end up looking like instance variable declarations instead of methods.
In C++ you should be using the typesafe functions std::fill and std::copy instead of memset and memcpy.
Unless of course you happen to be something akin to a cash-strapped startup, when you don't have those kind of luxuries.
There are two claims here:
1. are these people 'groups'
2. are they 'malicious or unhinged deceivers'

1 is easy - a 'group' is a collection or subset of a larger whole of people, which all of the named categories are. This is a simple semantic issue, completely uninteresting, but I still don't understand what point you're trying to make by claiming these people are not 'groups', apart from the non sequitur in your first sentence (when I say 'are these not groups', you say 'I have no reason to believe that they are malicious'). Of course they're not 'organized' as in that they have no central authority and there is strong disagreement about many things between them, but they're still 'groups'. But again this is a wholly uninteresting question and I'm not sure why you brought it up in the first place.

Then nr 2, the question was 'are they malicious or unhinged deceivers'. So that means they're either 'malicious deceivers' or 'unhinged deceivers'. Many (most?) are not 'malicious', but anyone who claims 9/11 was an inside job by the US government is 'unhinged'. (9/11 truthers are not 'anyone who wants an intellectually honest investigation into 9/11', they're whack jobs for whom nothing will ever convince them that they're wrong; much like the holocaust deniers in the OP.)

They're also 'deceivers' because they all operate to convince as many people as they can about their loony ideas, using all means possible. Repeatedly and without willingness to engage in actual, rational debate repeating claims of being 'oppressed', 'repressed' or 'silenced by the majority' is just the beginning of this deceitfulness.
Most consumer /hard drives/ lie about the result of fsync, as a 'performance optimization'.

It's generally possible to fsync, then cut the power before the data is physically on the disk.

yes, I think it was.

It makes a heap of assumptions though, and feels kind of like a non-techie person saying "why dont you just whip up a GUI app to trace my IP".
Enabling Nitro JIT for UIWebView for some applications without enabling it for every app in the app store is probably more difficult than toggling a switch.
This has been an engineering holly grail for quite a while. If validated, the patents for such magnets should make a nice financial windfall for this company. Great news if validated.
When someone is a 'malicious or unhinged deceiver', that means that they're either a 'malicious deceiver' or an 'unhinged deceiver'. I'm sure most people in the listed categories are 'unhinged deceivers' rather than 'malicious deceivers', that still doesn't take away from the point.

Actually I don't think I worried that the Airbnbs weren't going to be able to raise money. They were one of the top startups in their batch, and the top startups always manage to raise money. The reason I nagged Fred so persistently was that I thought he'd be a good match for them and I was annoyed that I couldn't convince him.
