Let's see... According to twitterholic the 1000th most-followed person on twitter has 75,000 followers. That means the 10,000th most-followed person probably has 7,500 followers, and the 100,000th most-followed person probably has 750 followers. This means the market for this product probably caps out at 10,000 or so users who both have enough followers to really move the needle and also something lots of people would want to buy. And that's probably including Facebook, LinkedIN, G+, etc. as sales vectors also.

I love the idea behind gumroad in theory, but the problem is that now not only do I need a great product but I need my own audience. This seems like one step forwards two steps backwards.

That's not to say suggest that gumroad is on the wrong track, especially since there are a lot of things you can do with this, but on its own I tend to be extremely skeptical of any business that relies on their customers already having lots of engaged followers.

This isn't surprising. If the set the AC bit on x86, then it will disallow unaligned accesses and you'll be operating in an environment more similar to RISC machines. In order to allow such a thing to succeed, GCC can't produce a 32-bit read from char* address since the alignment is only guaranteed to be 1 (i.e. no alignment) and this would trigger SIGBUS. Thus, in order to get a 32-bit read, you must deref a 32-bit variable, not 4x 8-bit ones. This makes even more sense on RISC systems where this "optimization" would be a tragic bug you'd want to work around in your compiler. See my post with the x86 assembly output confirming your general results.
I wonder who will be testing these things... Hope Google has a signup list like the had with the CR-48!

I like the sentiment of this idea, but sadly I think that this will be doomed to failure. It is unfortunate (but understandable) that the browser plugin is required even to read messages or posts by people using Privly. Crypto solutions need to be dead simple to be widely adopted. If users have to download extra software on top of what they already expect, then people like my parents will probably not use this.

It's one of many, many research projects in thermochemical hydrogen production -- the idea of splitting water using only heat (thermal decomposition), indirectly through longer chemical processes. It's been going on since at least 1977 [1], and there's 352 known thermochemical cycles for splitting water [2] (including zinc/zinc oxide), including the 14 listed [2] on wikipedia. The news today is that a grad student in Delaware built a small lab version of one of these, which he plans to run experiments with. His school media office wrote a press release for him [3], which was cloned by Physorg and written about on a few blogs.

In general, the idea (thermochemical hydrogen production) is just what you say -- heat in (solar, nuclear also researched), hydrogen out. No byproducts, as the chemical intermediates form a closed cycle.

Puts are expensive because the cost of borrowing? You are mixing two different instruments.

Borrowing occurs when you short NOT when you buy puts. Puts are expensive because of the stock's volatility (and exercise price). The higher the volatility, the more expensive the option (call/put) is. Just check the math of the Black-Scholes options pricing model.

I blame politics. A lot of young people are emotionally invested in the idea that "the System" is responsible for some people being poor and others being rich. If you acknowledge that some choices are good and others are bad, it challenges the view that wealth is predetermined and that income inequality is caused by fate/bias.
"[...]the humidity in the room, which had to be critically maintained at 60 percent — deviation either way could have resulted in an explosion large enough to destroy the entire base, not to mention the mountain that housed it and much of the surrounding area."

I'm going to assume that anything large enough to destroy the surrounding mountain would require at least one of the missiles/warheads to go (thermo-)nuclear. But my understanding is that actually achieving the Big Bang is really rather difficult to do intentionally, let alone by accident - at worst you have a few kton fizzle. So how is a small change in humidity able to trigger one or more of these weapons? (And, if one did successfully trigger, is it possible that it could daisy-chain the rest, or would they be torn apart before achieving supercritical geometry?)

Then again, I guess it's maybe possible that the supplies of conventional munitions and maybe nasty missile/rocket propellants could do some major damage, but a whole mountain?

Even more importantly, a high CTR with lower conversion rate would drive up your costs while lowering your sales.

In this case the first ad is very clearly for a game with a very clear target market. If I am in to racing games, I may click it and I may buy it.

The second ad could appeal to people strickly on novelty which means you may get a lot of customers who do not care about the product.

While the results of this post are very interesting and the conclusion to test everything is still good, we should look at the conversion rate to see which ad is actually more effective.

Ah yes the old "Google is evil ad company" shtick. You see an impressive new technology and this is the only way you can frame it to initiate a discussion??

But actually your scenario sounds plausible if Google was the most ignorant, narrow minded, child-like version of an ad network. If they have any smart people at all working at Google, I think that they would have a much wider, longer-term vision in which they can generate value from more than just bombarding you with ads in the most direct, obvious way possible. If they feel at all compelled to stay relevant and profitable for the longest amount of time possible, then they are working on that right now.

Also, I see essentially no hope for Y! though I'd love to be wrong. Consider:

(1) they should have owned the display rtb market. Instead, internal bickering and stupidity handed it to Google. Y! had the first rtb system (rmx), and screwed up so badly that the current next best rtb system compared to google -- appnexus -- is run by the former rmx cto. This will be the next business that is material to google's earnings and yahoo should have owned it.

(2) Scott is talking about ditching rmx and apt. Pray tell, what the hell is he going to run Y's business on, and why is it going to be any cheaper if they're paying for that software from someone else?

(3) They gave away search, and decrease market share and search rev every quarter. Golf clap.

A lot of enterprises use SiteMinder (aka ChannelSecure), which used to be Netegrity's before they got bought out by CA. It supports both Apache and IIS, although I'm not 100% sure what the policy servers run on, it might be Windows. But I have seen LAMP apps that integrate with it, for example. It really is just an intercept-and-forward system that functions as a module on the web server and puts a few things on the HTTP headers to allow apps to handle authorization by themselves.

How I won the victory over myself and learned to love The Timer
I should clarify. It is more the mentality of quick cash at any cost. This style of business can work in some work under some circumstances.

Orbitz does some cool stuff, but it isn't a startup. It was a spinoff from various megacorps.

37signals manages to work within the Chicago paradigm. However, they are run more like a small business than a high-growth startup.

Grubhub would be more a Chicago success story.

I don't think this is a matter of forcing users to choose between modern technology and privacy. Based on their current revenue models, some of the companies may cease to exist if they can't mine user data for advertising revenue. Then again, Facebook and Twitter could charge users with an agreement that their data won't be used, and they will see no advertisements. I wonder how many users would choose this alternative. It is doubtful many would. So with these 'choices', would privly just shut down companies that use this data as a basis for revenue if widely adopted? Would this be a real positive for users?

Revenues are generally as important or more than profits for a company at Groupon's stage (ie, young, high growth). Since its primary expenses are sales and marketing, it's easy to envision how such a growth machine could become wildly profitable (hence the $9.4b market value).

I think Y! Research has contributed

(1) hadoop enhancements (a friend works there on exactly that), which are a nontrivial cost savings given the size of Y's deployed clusters

(2) ad matching tech, which should be considered of the highest priority, given that Yahoo's business model is to make money off advertising. Small improvements in matching <users, stories, ads, context> can easily lead to material improvements in earnings

Why Y! doesn't consider the two above things important is beyond me. Also, one of their recruiters sent me an email this week! Dude has big old brass ones, that's for sure.

Amazing list. I would perhaps add to this the "market sophistication level". In this particular case (saturated market and lots of high quality competition), ethos is highly important.

The ad is successful in empathizing with customers by display a drawing that follows the design of top-of-mind ad very current memes. This works because of the market sophistication level (i.e. potential customers knows how this particular video game works).

Consider that a while back, that was the only way to learn programming.

Personally, I think Python is a great way to teach programming, because it allows us to get to concepts quickly. Accidental complexity is at a minimum, and the inherent complexities of programming become the focus. But, even thought that's my personal preference (based on some experience; I've used Java and C++ to teach programmers and had to explain away accidental complexities), I hesitate to say it's best because I have no evidence backing up that claim.

What's important is learning certain concepts, perhaps the most important of which is algorithmic thinking. That is, knowing what result you want, knowing how you start, and being able to reason through how to get from the start condition to your desired result, step-by-step. What helps is when the result you get is something you care about. I can easily see that for some people, getting something to behave a certain way in a videogame will be a more compelling result than others.

Offering a conducive environment will always necessarily benefit others. If it didn't it'd simply be called a reward. Gay marriage proponents obviously call these assumptions into question, but unfortunately offer a worse alternative.

While there may be reasoning to support limiting marriage perks to those who procreate, that only hurts their argument that those benefits should instead be extended to gays who are least worth incentivizing.

>How does storing state in a microscopic state turn a computer into a microscope? I assure you that no computer hardware works by looking at stored state with a lens and using computer vision algorithms to determine the state of the device.

Oh sorry. It's a somewhat strange concept I admit, but it's served me well. There are a couple of ways to motivate it. Let us say that a computer has 4G of memory (roughly 10^10 bits). That is a vast amount of data. If that were to be printed out into a sheet of paper, with each bit a dot about what the naked human eye can see (call it .1 mm square) then it would be a sheet about 10 square meters (10^5 * 10^-4m = 10m^2).

The actual size of a 4G RAM chip is more like 1mm^2. This is a reduction factor of 10,000.

Let us say that a physical screen operates at the density of our original printout . This implies that the software sitting between the display and main memory is essentially functioning as a microscope, making visible to the naked eye a sheet of paper that is 10,000x smaller than we can see.

But if we consider information rather than data, the magnification is an order-of-magnitude higher, at least. (A screenful of characters 10px on each side requires 100bits, whereas the codepoint takes around 8bits.) And of course if we consider hard-drives rather than main memory, realize that a TB is roughly 1000x main memory, or 1000 sheets of paper, each 10 meters square (about 310 square meters).
