Ads are not the only model for providing free rides. Other Sustainable models exist:

Peer balancining: producers earn free credits for consumption. This is how Internet backbone peering and Team Fortress 2 work.

Freemium, or light users are too cheap to meter, while heavy users pay. This powered Zynga's IPO and many prosumer niches like Photography and web analytics.

Open core with professional services for customization or support (a mix of Freemium and free software). Cloudera.

How is Facebook different from telephone service, or USPS, or an ISP, under your analysis?

(Sidenote: USPS actually is ad-supported by bulk mail, and "heavy users subsidized" by parcel post. First class letter postage is really a nominal fee to eliminate DOS and DDOS attacks. )

At the that scale, CPU and developer time are mostly orthogonal. If you need to crunch 1000x more numbers, you won't be able to program your way out of the problem. If your code is 1000x inefficient, it should be easy to optimize a bit. If you really need 1000 machines for just one hour, setup costs dwarf compute costs. If you need 1000 machines for a year, you will need someone to administer the work and wrangle the data.

What does your scale mean? Paying nearly nothing to get to -80 is a great deal compared to speculative painful expensive surgeries and drugs.

Why would you use a credit card company that locks yo right account, ever? Fraud is the merchant's problem, not yours. Fraud investigation is a courtesy you provide to merchant customers, so the CC company should never have any reason or lock your account without your permission, unless they have tried and failed to reach you for close to the fraud-liability time limit.

It takes less energy to accelerate an object away from both the Earth and sun (assuming your launch pad is on an appropriate spot on the Earth surface), than to accelerate an object away from the Earth but into the sun without just getting the object stuck in an orbit like Venus or Mercury.

It is interesting how games differ from sports or academic contests. In sports, losing is OK because it makes you work harder to become stronger or smarter. In games, losing (or winning) is almost pointless because getting better at the game doesn't make you better at anything else in your life; so the value is in feeding some emotional or anesthetic aspect.

If your players are mutually anonymous, have the worst player play against multiple other teams each week, soaking up the losses. Each player gets their own Potemkin village where half their opponents are actually copies of the worst player. Now you have 1 loser instead of 31.

I recently started reading now algebra book with a goal of understanding the Galois theoretical proof of his understanding unsolvability of the Quintic. This is generally considered the capstone of a complete 2-semester undergraduate study of algebra for a math major who is not pursuing graduate level pure math.

The interesting part IMO is the analysis of those normal subgroup chains and understanding the isomorphism to splitting fields.

Definitions and theorems without proofs or examples or illustrations is like the box without the gift inside. That post built up a pile of terminology but then ended before showing any content. It shows where to look out find the solutions at least.

Build an HTML generator of function PreHtml -> HTML that is quirk compatible with all browsers. Yes, you will has many bugs to fix over time. Now have all your templates code emit output of type PreHtml and your final page generation phase is the function above.

Pay attention here: any template that attempts to emit HTML will fail to Typecheck.

Not a panacea, but static enforcement of Don't Repeat Your Bugs, even before those particular bugs are discovered.

That doesn't matter so much, because this project is about highlighting delicate code regardless of reason, not assigning blame.

Conflict of interest how? Isn't their more of a conflict of interest when a drug developer is paying the fees of the drug tester?
