markerdmann··on Coin toss not random after all
According to the article, you could still bias the toss. For example, let's say you're trying to get heads, which in your system is "first heads, then tails". You would hold the coin heads up on the first toss, and tails up on the second toss.

markerdmann··on How twitter helped a technology consultant escape from an evil hospital
This article in the New Yorker is excellent:

http://www.newyorker.com/reporting/2009/06/01/090601fa_fact_...

Atul Gawande argues that the problem with healthcare in the US is overutilization.

The surgeon gave me an example. General surgeons are often asked to see patients with pain from gallstones. If there aren’t any complications—and there usually aren’t—the pain goes away on its own or with pain medication. With instruction on eating a lower-fat diet, most patients experience no further difficulties. But some have recurrent episodes, and need surgery to remove their gallbladder.

Seeing a patient who has had uncomplicated, first-time gallstone pain requires some judgment. A surgeon has to provide reassurance (people are often scared and want to go straight to surgery), some education about gallstone disease and diet, perhaps a prescription for pain; in a few weeks, the surgeon might follow up. But increasingly, I was told, McAllen surgeons simply operate. The patient wasn’t going to moderate her diet, they tell themselves. The pain was just going to come back. And by operating they happen to make an extra seven hundred dollars.

markerdmann··on Microsoft’s Long, Slow Decline
You make a good point, joechung, and I've been trying to find the related statistics. This is what I've been able to come up with so far:

Apple had 14% of the US retail PC market in Feb. 2008 -

http://www.appleinsider.com/articles/08/03/17/apple_snags_14...

This article claims the number was 8.7% in the 2nd quarter of 2009 -

http://www.appleinsider.com/articles/09/07/15/single_digit_g...

According to this article on theappleblog.com, Apple has 4% of the global PC market as of July 2009 -

http://theappleblog.com/2009/07/25/does-apple-have-a-91-perc...

If anyone has more, I'd be very curious to see them (especially the ratio of sub-$1000 retail PC sales to $1000+ retail PC sales).

I'm a fan of the skip button. It made my user experience a more comfortable one, and in the long run made me want to vote more often. I felt like I had a certain degree of freedom, which made this a refreshing break from the sort of pushy UI that tries to force you to act in its own interest. As a consequence, I felt a stronger impulse to contribute by voting.

It would be interesting to see a table showing each phrase you tested along with its clickthrough rate.

markerdmann··on China’s College Entry Test, Gao Kao, Is National Obsession
This also reminds me of a quote from http://news.ycombinator.com/item?id=582698 that has been on my mind:

More serious for China's long-term prospects is that the expansion was so fast, and the pressures to pay off the debts so intense, that many of the schools turned into diploma mills, churning out poorly qualified students. Mr. Zhang got his degree from a school of traditional Chinese medicine with no history of teaching computer sciences. He looks back ruefully, recalling overcrowded classrooms and a lack of materials: "I wonder if this education was of any value?"

It sounds like there is a huge opportunity here. If open-sourced course materials (such as MIT's OCW) could be combined with a degree-granting mechanism that had credibility with employers, then ad hoc schools, study groups, online communities, and even lone inviduals could succeed where these hastily retooled "universities" seem to have failed.

markerdmann··on China’s College Entry Test, Gao Kao, Is National Obsession
The article's comparison to the SAT is misleading. Whereas the SAT is a reasoning test, the Gao Kao is a series of subject tests (think SAT Subject Tests or AP exams). The three mandatory subjects are Mathematics, Chinese, and a foreign language. In addition, students select one to three additional exams, and this choice depends on what they hope to study in college. Prospective science/engineering students will choose from Biology, Chemistry, and Physics; prospective arts/humanities students will choose from History, Geography, and Political Education.

markerdmann··on Umm guys, parrotsecrets.com no longer sells an ebook.. were we scammed?
Yesterday I received the first 12 pages from the ebook author. I found her on Elance, and I'm paying $800 for 30 pages. Elance was very effective: I received over 30 bids for the project, several of which came from extremely qualified writers (including two PhDs). While I wait for the book to be finished (another 3 weeks), I'll be working on building the site and planning the marketing strategy.

If you'd like to discuss it in-depth, Ryan, feel free to contact me via email or Gtalk.

markerdmann··on Umm guys, parrotsecrets.com no longer sells an ebook.. were we scammed?
As an experiment, I'm currently cooking my own site (for a different market) using the parrotsecrets.com recipe (as it was described in Robert Cringely's post). If people are still interested in this, I'll make sure to post the results to Hacker News, including all of the relevant data such as anonymized traffic logs, financial results, etc.
markerdmann··on Umm guys, parrotsecrets.com no longer sells an ebook.. were we scammed?
There seems to be a "time-limited" 50% discount which is always available, so it ends up being $40.

If you subscribe to the free emails, you'll eventually get this link:

On that page you can buy the ebook set for $40.

markerdmann··on Ask HN: Which books and open source projects make up the programming "canon"?
Why do you think that?
markerdmann··on Ask HN: Evolution writes very poor code. So why is biology research rewarding?
If someone who is not a programmer looks at your code and pronounces it utterly incomprehensible, does that make it inelegant?

What exactly would "evidence" of something as subjective as "elegance" look like?

markerdmann··on Ask HN: Evolution writes very poor code. So why is biology research rewarding?
If you're looking at all of the code that evolution has ever written, then yes, I suppose you could say that most of it is very poor. The fraction of code that survives and propagates, however, is awe-inspiringly beautiful.

If you're looking for some insight into what makes it so beautiful, The Selfish Gene is an excellent place to start.

markerdmann··on The Incredible App Store Hype
Your comment inspired me to brush up on the California Gold Rush, and this quote from Wikipedia made me chuckle:

"Sutter was dismayed by this, and wanted to keep the news quiet because he feared what would happen to his plans for an agricultural empire if there were a mass search for gold. However, rumors soon started to spread and were confirmed in March 1848 by San Francisco newspaper publisher and merchant Samuel Brannan. The most famous quote of the California Gold Rush was by Brannan; after he had hurriedly set up a store to sell gold prospecting supplies, Brannan strode through the streets of San Francisco, holding aloft a vial of gold, shouting "Gold! Gold! Gold from the American River!" With the news of gold, many families trying their luck at Californian farming decided to go for the gold, becoming some of California’s first miners."

markerdmann··on The Incredible App Store Hype
It's amazing how well this strategy of hyping the extreme cases has worked for Apple in terms of getting a ton of people to develop for the iPhone. A number of my coworkers have been busily writing iPhone apps in their spare time, and they keep at it no matter how many times I point out that the market is oversaturated.

markerdmann··on Poll: What kind of cell phone do you have?
It's been stable so far, but I'm also using Opera Mini a lot.
markerdmann··on Poll: What kind of cell phone do you have?
I completely agree with you about the camera, but so far I haven't noticed any slowness. The speed is actually what sold me on the E71 over the iPhone and G1, which both seemed too laggy.
markerdmann··on Poll: What kind of cell phone do you have?
The Nokia E71 is a dreamboat. I'm using it mainly for browsing, email, maps w/ gps, and ssh, but the call quality is amazing. Whereas in the past I would have to repeat myself at least once in every conversation, with the E71 I can rely on the fact that the person I'm talking to will hear what I'm saying.

Also, chicks dig it (when you're a programmer, you have to snatch those points wherever you can ;-).

if you had actually bothered to skim the table of contents, you would know that the book includes a chapter about erlang. ;-)
