Facebook is relatively new to the advertising game and probably doesn't have the sort of experience that Google, MSN and Yahoo have in dealing with the immense amount of click fraud out there.

Worked 3 years in online advertising, dealing with billions of impressions and millions of clicks daily. 80% fraud rate isn't unsurprising, probably is actually higher. Most mature ad networks can easily filter and reject a substantial portion of the fraud, or at least not bill the client for it.

Groupon actually has substantially changed their payout terms, from their 10-Q http://investor.groupon.com/financials.cfm

> Our current merchant partner arrangements are structured as either a redemption payment model or a fixed payment model defined as follows:

> Redemption payment model - Under our redemption merchant partner payment model, we collect payments at the time our customers purchase Groupons and make payments to most of our merchant partners at a subsequent date. We utilize this model in most of our international operations as it conforms with the local market practice. Using this payment model, merchant partners are not paid until the customer redeems the Groupon that has been purchased. If a customer does not redeem the Groupon under this payment model, we retain all of the gross billings for the Groupon purchase. The redemption model generally improves our overall cash flow because we do not pay our merchant partners until the customer redeems the Groupon.

> Fixed payment model - Under our fixed merchant partner payment model, we pay our merchant partners in installments over a period of generally sixty days

Thank you Dr. Obvious.

http://hyperpolyglot.org/scripting is a similiar resource for php, perl, python and ruby only.

I use http://sugarsync.com personally which provides versioning and also lets you arbitrarily sync directories, not just the 'dropbox' one.

He already told you, they are good with the goddamn customers. They have people skills, they are good at dealing with people. Can't you understand that? What the hell is wrong with you?

I don't disagree nor do I use heroku, it's moot for myself.

I was just commenting how row-limitations were a very NoSQL way of enforcing data limits and inappropriate for an RDBMS.

I like that you guys pointed out more efficient ways to do stupid things :)

I disagree. By restricting the number of rows I think you're just going to end up with folks creating sloppy schemas specifically to avoid going over the limit.

  post.categories (varchar) = "1,51,78,84,100"

and other wonderful non-normalized approaches.

Is making otherwise innocuous changes which have a substantial impact on user behavior important to the startup culture?

No, no at all.

I fantasize about computers too. I tried to picture clusters of information as they moved through the computer. What did they look like? Ships? motorcycles? Were the circuits like freeways? I kept dreaming of a world I thought I'd never see.

Nice try, overpriced US universities and for-profit degree mills.

Awesome response from Spolsky but that's not Quora. You can tell because it has users and content :)

Why do you think you'd only get paid $33k? If that's the case, that's suggesting the compensation and ownership is:

  Co-Founder: $33k Salary, 45% Equity
  Co-Founder: $33k Salary, 45% Equity
         You: $33k Salary, 10% Equity

I'm hoping the problem is self-evident.

Yes.

In 2008/2009, another engineer and myself built an ad-platform that received around 500M impressions per day, 5M clicks per day. And it wasn't just recording a tweet or publishing out to followers. We took the user input query, had to do some keyword/relevancy targeting, geofiltering, matching to advertisers and deliver back a large result set of adverts. All within 100ms.

Our platform was also apache, mod_php, memcached, mysql and rabbitmq. So definitely not the most optimal of platforms by any means. We had two colos with ~20 servers (dell r410s) at each facility.

Twitter just recently announced 400M tweets/day. I'm not trying to brag about my experiences, because looking back now we made numerous amateur mistakes, but just showing that Twitter's "scale" is a joke compared to everyday challenges at any large internet ad network.

What unit suffix is 'l'

Twitter's attitude is laughable. Yes, you have a decent amount of traffic but you're also only dealing with ~160 uncompressed bytes (plus whatever overhead) per event. The hurdles you've overcame aren't that particularly amazing nor challenging.

Yeah, just not cutting it for me. I understand the workarounds but the reality is they shouldn't be required. I should be able to right-click a directory and "Add to Dropbox"
