I'm still trying to understand how the whole system works. It appears to be groundbreaking but I'm not really sure. The last sentence in the document should catch your interest:

"As a result, we have a cryptocurrency protocol whose codebase is very small, and yet which can do anything that any cryptocurrency will ever be able to do."
Someone whose stock property ("paper") can be valued as > $1M, i.e. If they sell their TWTR stocks now they will be 'actual' cash millionaires.
It's easy to argue that abstract privacy as a concept separate form physical privacy simply did not exist at that time in history because of a lack of electronics. A corollary is that they probably would have added abstract privacy if they had had the benefit of hindsight.

Our side project (http://grabaperch.com) ultimately became our main business. We're a couple of developers, when we launched four and a half years ago we had little to no marketing knowledge. So I have learned by experimenting.

We launched into an audience we knew well, and already worked for. The product is pitched at web designers, as a consultancy the majority of our clients were web design agencies. Our main initial tactic - and something we still do - was to write content that appealed to that audience. Not necessarily anything to do with content management, but anything that might appeal to designers and design agencies and then link back to Perch.

I've experimented quite a bit with BuySellAds (http://buysellads.com/). There are bargains to be had that convert well if you look at the smaller sites, and find those that are well matched to your audience. They might not send through huge amounts of traffic but if they are really well selected then the conversion rate can be better than the expensive high traffic sites.

The surprising success for us in terms of advertising has been sponsoring relevant podcasts. In our case that is podcasts that target web designers. The trick is to sponsor those who actually take the time to talk a bit about the product during the show - rather than just read out your name at the beginning. We've also managed to find podcasts where the hosts use Perch - that's even better!

Mostly it is just working on incremental gains in terms of traffic and visibility. An article here and there, some well placed ads, sponsoring podcasts. None of this causes a crazy rush of traffic but we're in it for the long game, so a steady growth that is sustainable is really more interesting to me.
Except it pays the wrong people. In Bitcoin, at least, miners are kept honest by other people running nodes that limit what miners can do. In this protocol the validation would become very expensive but only the miners are paid. This sounds like trouble.
I like the idea: "don't track searches".

I've visited your search engine. Looks like you call Bing's API to get the result. The catch is: you don't get the images back since Bing does not have them either.

So why shall I just use Bing instead? Perhaps you are stronger in the "News" search?
The term "paper millionaire" means exactly as it sounds - someone who is a millionaire, but strictly on paper.

Most of the shares these Twitter employees have received cannot be sold until a certain amount of time. So the money is "on paper". They don't millions of dollars in their bank accounts - rather, they simply owns shares that are worth a million dollars.
The fact that both wages fall a similiar percentage relative to 2007 only tells us that the gap between both wage classes remained the same

Well, no. In dollar terms, the gap would have become smaller.
No it doesn't. Or rather— it's not necessary or sufficient: you can already trade distributed cryptocoins, and no amount of cryptocoin magic can completely distribute USD or other non-cryptocoin assets because their differential counterparty risk makes every promise different.
Umm, what?
Wages denominated in USD become less with inflation.
Wages denominated in BTC become MORE with deflation.

Why would you get paid less? Deflation means the wage you get paid is worth more. Inflation means the wage you get paid is worth less.
First hit on Google. "An individual who has achieved a high net worth as a result of the large total market value of the assets he or she owns. This phenomenon usually occurs when investors buy marketable securities that are later bid up to much higher prices on the open market. While this creates large amounts of "paper profit", the paper millionaire's riches usually aren't safe until these holdings are liquidated."
yes. :)

BTW, also contact me if you want help investing in alt-coins. I'm going to start an alt-coin hedge fund.
Unless one considers the lack of Turing-completeness to be a feature (as Bitcoin apparently does, pointed out in a few other comments here).
A somewhat different perspective exists in India. Most large corporations (and a large number of startups too) dissuade people from eating at their desks. Because most Indians love and eat cooked food, which, well, tends to give off the odours of cooked food. An entire floor eating cooked food at their desks will inevitably lead to a lingering odour that settles over everything & everyone.

So many of us have two options - eat out at a nearby eatery, or eat your prepared lunch at the internal cafeteria.

Personally, and in my circle of friends, we've gone from preferring eating out to preferring eating cooked meals that are either bought at the cafeteria or brought from home.

Maybe it's our preference for cooked food, which after a few years of eating out, will always be healthier if you get if from home. And because many of us have the "luxury" of being able to hire cooks who come in the mornings/evenings.

There are of course many Indians who prefer eating out, but as they get older (read: 4-5 years of working), they start realizing that home-cooked food is a better proposition. Which is why you'll often find a broad cross-section of employees - from an entry level person to CXOs, bringing cooked food in insulated containers as lunch.
Some are pretty good. You'll find that early documentaries tried to convey more information, I guess they figured out dumbing things down made them more entertaining.

Take a look at this Feynman documentary from 1964 for a case in point:

^ This. Exactly!

Thanks for articulating the thought process I'm having almost every day right before lunch time.
I am strongly against the so-called lunch interview as well, if the candidate is already scheduled to meet 4 or more persons.

When I am scheduled to have lunch with candidates, I never brought up any topics related to work, unless the candidates did it by themselves. It is exhausting to have an interview of 4~5 hours, and talked about your projects or work experiences many times. So at lunch, it is best to relax and eat. The candidates have to be well prepared for the afternoon. It is never to our best interest to make the candidates so exhausted so that they might not be able to perform well and thus we might miss good potential employees. So I prefer to have light conversations, no work . If the candidates fly from other cities, I will introduce the city, the neighborhood, and the life around. If the candidates are interested in any specific parts, like housing, schools, parks, bars, restaurants, etc. those would be very good topics.
Do you have a number in mind?
Depending on your service provider (hosting, msp, mttos, whatever), the up-front msa can be truly painful if you want "real" service. I.e., redundant power and multi-provider network connectivity with multiple connectivity points that have a massive capital cost but will be as reliable as your commercial or home utilities.

Couple the cost of establishing the relationship (especially with startup credit) with the NRC and MRC of hosting services, smart hands rates, reserved cabinet or cage space for those surprise boxes on the dock, and incremental pricing models, and it's very difficult to build out and manage poorly predicted growth in a financially constrained environment.

Saving money on this means you're allocating additional engineer hours to dealing with this yourself.

The 'middle road' is probably an operator in a decent NAP or superNAP that manages the big lease and then carves out a margin by offering smaller space, possibly even colocating your hardware in the same rack as someone else's (and maybe not in the same rack with your other gear), and charging more than a macminicolo but offering significantly improved and variable services.

There are a number of walls you can hit that will present themselves as an almost insurmountable obstacle when you own your own gear. There are mandatory professional services when setting up some gear (SAN vendors have been notorious for this) and it's just a bunch of attention you have to devote to something for which there is generally a good enough solution for a company that may not exist long enough to depreciate the servers that ate a huge amount of their startup capital.

It's not that we're 'afraid' of computers. It's like saying we were afraid of electricity or telephone lines 40 years ago. We can manage it, but it's almost irresponsible and risky to do so.
Ask HN: Any international F1 kids got internships in the US?
So I've been here for over a year, studying in one of the best CS programs in the country, working on a LOT of projects, with research experience. My resume [1] has been able to fetch me interviews with a ton of companies - both big and small - for summer SDE positions.

I know this for a fact that I have nailed all my interviews. They have all gone as well as I expected, with great feedback from the interviewers afterwards. But for some reason, I have been unable to get an offer.

This has made me really, really demotivated. Is it because I'm international, and it's hard for companies to get H1 visas in case they want to extend a full time offer?

I just want to know what to make of all this? What id going wrong? What should I fix? What do others think of this?

Austin, TX is worth considering. Lower cost of living, especially with a (less than insane) commute. The city even gave itself the moniker "Silicon Hills" in the '90's, and there's a thriving tech & startup industry in the area.

I loved Everpix and wanted you guys to succeed. But when I finally heard the bad news, I thought Amazon should buy Everpix and make their cloud drive super awesome with it (Right now cloud drive is nearly terrible).

Everpix was a great product and I still can't believe there is no one who sees value in it.
If you're not actively logging and auditing all SELECT * queries on tables storing credit card numbers... shame on you.
I wonder what the turn-over rates are for most startups. I was recently let go from a start-up that over the last two years has seen 200% turn-over (3-people team, 6 new hires didn't make the cut).

I've also spoken to a friend just left a start-up that he figures has had 90% turn-over since he arrived a year ago, and the start-up is just two years old. So, if the past year is any indication, about 180% turn-over on a team of about 18.

Is this really that common? Or am I just hearing of the horror stories?
If you're paying H1s less than locals you're violating immigration law. The idea behind the H1 program is to help you when you cannot find local expertise in your specialty and need to recruit globally. It's a very sensitive issue in the USA if you are bringing in less expensive foreigners to "steal" jobs from locals.

That said, it's prone to abuse and I have seen some H1s with really poor compensation due to a weak negotiating position (the difficulty of switching jobs while in-country, sponsored adjustment of status, etc.).
The problem is that the tests are flawed and the native speed being slower as virtual is a pretty big red herring for that.
That's OK because benchmarking that tests what you are after is actually very difficult. Small assumptions can create big differences.
If you can't guarantee that the data has actually been written to the disk then you're testing caching mechanisms, something you already point out in your article, but then you're no longer testing file system performance as the article claims it is benchmarking. The problem is that we don't even know which caching mechanisms (guest OS, hypervisor, hard disk driver) or that the conditions are always the same.

A typical thing that performance benchmarks do to negate guest OS caching is to process significantly more data as what the available RAM is set to. For example, if your guest OS RAM is set 512MB, process 10GB of random data. Of course then the question is how-to get random data as you don't want to end up testing the random generator ;) or your host OS caching.

Another way to make sure you test data committed to disk could be to include a "shutdown guest OS" part and measure total time until the guest has been fully shut down.

I know that at least VMware has the ability to turn off disk caching (in Fusion, select Settings, advanced "Hard Disk Buffering" <- disable).
I am not aware of a similar feature in Virtual Box, it might exist though.

Even while you tested the same guest OS, we don't even know if the hard disk adapters where both using the same hard disk drivers.
Performance differs between IDE/Sata/SCSI drivers. SCSI drivers have queue depths, IDE drivers have not.

Denomination is a wei. Weis are tied to compute jobs, basically. It's a distributed computing network/server with built-in trust. Holy shit.
Trying to figure out a couple things (from pastebin link):

1. What protection against non-halting?

contracts are "funded" upon creation, and by those who issue transactions to the contract. if there are specific fees required by the contract to perform an action, it must be enforced by the contract itself. the cost of computation will eventually exhaust the contract's funding it fails.

2. what are the long-term economics? (i.e. is coin supply unlimited or limited and at what rate of decay)

line 90

- planned fundraising period with issuance of 10000 ether per BTC contributed

- other coins will be issued so the initial money supply is 15000 times the contributed BTC amount, with 0.25x (i.e. 16.67%) to the founders, same amount to fund the Etherium organization. Division of BTC not specified.

- the mining reward will be 1/3 of the initial supply, per year, perpetually (i.e. 1/2 the contributor's reward.) So the money supply increases linearly.

3. if a person's only goal was to use the blockchain to store data, what would be cost per byte, and is there a max rate?

line 385 to 399

- A contract is "funded" when it is created, and the computation performed by the contract consumes the funds.

- storage of a "data item" in contract memory costs 100x where x = floor(10^21 / floor(difficulty ^ 0.5))

- don't see the limit/cost of data items bound to transactions as per transaction definition on line 133

anyway it takes courage to name a currency after a drug like ether.

I think liquidity is a key distinction. Many of those Twitter employees are in a lockdown(?) period post IPO where they are not allowed to sell their shares (typically 6 months). Thus they don't have the option of becoming cash millionaires right now. (Many startup founders are this way post series A)

Compare this to a case where someone owns $1MM worth of Google shares, purchased on the open market. Even though they don't have cash, it's basically as if they own cash, since you can liquidate the shares right away.
Speed your movie up from 24fps to 25fps; it should make a huge difference.
Using a search engine is an art in itself. You've become accustomed to the way Google works.

Do you assume that Google is the way a search engine should work and all other search engines should follow that? That is, should all search engines produce the same output given the same input?
I don't think the poster was being snarkey, they were merely pointing out how hard it is to write correct C code. And there was no criticism of the developers, in fact the post implied that the bugs were the fault of C and not the developers.
Well, I did phone interviews with both Amazon and Google (both in their UK offices), and while I got rejected, I found both companies very professional. Google called on the phone within 2 days and Amazon send an email the very next day. Also I really hate phone interviews ...
Bakrie is one of the big players in the politic of Indonesia. It makes sense for him to try to control the (maybe 2nd) most used social media platform in Indo. He probably expects to have the same influence as what Obama 2008 digital campaign team had.

I did some spreadsheet-ing to look at the "profitability" of their userbase. If the business were sustainable, then Monthly Recurring Revenue [1] would be higher than the cost to service the customers [2]. If not, then growing the userbase just increases total monthly losses (assuming a steady freemium conversion rate).

In Everpix's case, it appears they were growing unsustainably.

Their data shows that all the way up until February 2013, they were spending $3 on AWS for every $1 of MRR. That's scary, because it means that a new customer bringing $1 MRR was actually increasing their monthly losses due to usage costs!

Things got better though. In March and April 2013, a surge in premium users seems to have shifted the balance in the right direction. But still, for May 2013 until the shutdown they were spending $1.20-1.40 on AWS to service every $1 MRR.

So growth in their userbase was actually increasing their total burn rate, which makes growth unsustainable.

You can see the spreadsheet analysis here:

The main problem with the term "White Knighting" is it's nearly always misused as a way to dismiss someone's valid argument. It's a discussion killer, and contributes nothing at all constructive. Even if the term really does apply in a given case (and that will almost never be true), it still doesn't help to use it.
My theory is that when everything is automated, so will food production also be, assuming there is enough energy in the world for that. Then everyone will need very little money and Everpix can charge much lesser amount of money...thus still keeping number of users the same.

Clojure Conj 2013 Keynote: Russ Olsen - To the Moon [video]
$30K/month and ~100 servers seems like a huge waste. I'm in the business of managing similar services. I handle, not photos, but video streams. My work is for one of the largest companies in the world (Fortune-5) and I deal with things like superbowl traffic spikes, etc... Everything is handled in house but for spiky loads, we look to things like Akami.

I realize managing at Fortune-5 is different than 100% oursourcing but the cost constraints, I have to imagine, are very similar. For example, I have to imagine Amazon gets similar price breaks from Cisco as my company - I know Amazon has custom built servers and all so there may be some advantages but at $30K/month, I think any hosting company would happily take 1/2 or 1/4 of that.

I'd be curious to know what kind of bandwidth loads you were pushing through AWS and how much of the AWS cloud can be made redundant per client.
I had a phone interview with Amazon. It too, was with someone with a heavy accent I had trouble understanding. To make things worse, I could tell that the guy was giving the interview from home because there were children yelling in the background.

To make things even worse, the interviewer had trouble understanding my english. How do I know? Because when he told me the answer to one of the questions I had gotten wrong, he repeated back the answer I had just given him.

It was really frustrating.
This is not news. I experienced the same thing at Agilent in San Jose.
Napoleon Bonaparte believed there was a star in the sky that was dedicated to him.

Men seem to have a higher opinion of themselves and are more willing to invest in their sometimes farfetched ideas. Some of those farfetched ideas have turned out to be valuable and have harvested a bounty.

Awareness of bounty results in more people taking more risks and chasing after their hairbrained ideas, a few of which are share a wide appeal.

The California gold rush is a good example, a time when many San Francisco merchants became rich.

Only a madman would pursue a dream that reaped no harvest and many do.

Most often I would see a savvy recruiter pair up the lunch with the referrer so they could catch up with their friend and it would act as the 'sell' part of the interview slate.

This is a functional and smart practice.
A good estimate would be how much LINE has been able to charge for their stickers there.
There are _a lot_ of dedicated options. In terms of price, Softlayer's at the high end. If Softlayer gives you a price/performace improvement over AWS of 2.5x, you can get another 2-3x that by picking a cheap (but not necessarily bad!) provider.
From business point of view, we want to push our ads to the users. So forget about buying "likes", but use "Clicks to Website, Website Conversions". Anybody has any successful story on that kind of ads on FB?

Totally correct. For me the interview/negotiating process is not finished until I walked into the office on my first day of work. Prior to that, anything can happened.
The exact same force is used in seizing a hammer or other object as in seizing a house. In both cases law enforcement will eventually arrest you, put handcuffs on you and take you to jail if you do not comply.

" When we are targeted, we always see the outdated ads from 9 out of 10 websites we visited but don't like to re-revisit"

this is very true. You have just listed a billion dollar idea. If I search for an adidas shoe or just go to a company website then I start seeing ads related to those just visited sites - how boring. Retargeting just seems to be plain stupid instead consumer should be showed more variety
