michaelf··on McClure steps back at 500Startups after internal sexual misconduct investigation
Seriously, I think "Always Sunny" explains it best (i.e., because of "the implication")

michaelf··on How the CIA Helped Produce 'Zero Dark Thirty'
Similarly, The Paris Review was founded by CIA agent (and novelist and National Book Award winner) Peter Matthiessen[1] as a form of "cultural propaganda"[2].

michaelf··on The cost of Linux's page fault handling
Can anyone hazard a guess as to how Linus was able to measure the cost of a page fault and an iret so precisely? What tools and techniques might he have used?
michaelf··on When You Criticize Someone, You Make It Harder for that Person to Change
The author references the work of Barbara Frederickson, a psychologist who had a very popular theory on "Positivity Ratios", a theory that was in part justified by misuse of differential equations from fluid dynamics, and was thoroughly debunked in "The Complex Dynamics of Wishful Thinking: The Critical Positivity Ratio" [1].

There have been several good summaries of this paper and the work that led up to it over the past few months (my favorite being this [2] one).

I'd take this author's view with a grain of salt (or something stronger).

michaelf··on Steven Sinofsky to Leave Microsoft
Ditto.

It seems very weird to put the word "experiences" in quotes. It makes it seem as if the writer is using it sarcastically, or is in some way disclaiming what they are writing. What in the world justifies the quotes, and why wouldn't an editor get rid of them?

michaelf··on The Mystery of 355/113
Is it also the case that all transcendental numbers have approximations of unbounded quality? Or only that Liouville numbers have approximations of unbounded quality, and therefore cannot be algebraic?
michaelf··on Send faxes & sign documents from Google Drive… powered by HelloFax
FYI, I was about to join up, but I declined because it wanted my contacts.

For the most part, contracts are signed by relatively new contacts (people not yet in my address book). E.g. new customers, partners, contractors, or employees.

I hope you'll get rid of this unnecessary intrusion into my privacy in the future. And, for what its worth, people who send around lots of NDAs, LIOs, term sheets, employee agreements and other sorts of contracts usually value their privacy.

And yes -- I understand that you say you won't be spamming my contacts or mining it for data. It's just that I don't know you.

michaelf··on 53% of Recent College Grads Are Jobless or Underemployed—How?
I can't agree more. When I was a freshman, I was required to do a work study as part of the deal for my loans. I didn't want to do it -- my course load seemed hard enough -- but I found a job as an "undergraduate research programmer" at a small computer-vision oriented lab at my school. I worked around 10 hours a week during the school year, and 40 during the summers. Particularly during my freshman and sophomore years, I felt completely useless. But, even without noticing it, you pick up a LOT just by struggling with it (e.g. gdb, complex build systems, working with legacy code, version control systems, common patterns of software development, and how to get into a flow state even while hacking on bits of software that aren't all that interesting to you personally). By the summer between my sophomore and junior year, I was finally starting to feel a bit productive.

In any other environment, I would have never had the opportunity to be a completely worthless drain on resources for so long.

So certainly avail yourself of any opportunity to get a job while in school. I was lucky in that I was essentially forced to do it based on the terms of my loans. Any parents reading this: see if you can do your kids a favor and secure them a loan that requires your kids to get a work study, coop, or internship. And no, working as barista at the campus cafe doesn't count!

michaelf··on Gamifying Algebra
I'd think that a huge benefit "gamification" is that it allows students to learn at their own pace and without much teacher guidance. Kids figure out how to play Portal and Civilization, for instance, without a teacher hovering over them to tailor their lessons.
michaelf··on New: Apply to Y Combinator without an Idea
Is this the first step in YC pivoting away being a "seed investor", where the goal is to pick winners? Does PG see the future of YC as being an alternative to post-graduate education where the goal is instead to develop winners and have a stake in their success?

If this model works out, I wonder if we'll eventually see traditional universities funding startups for top students out of their endowments.

Very exciting experiment, if you ask me.

michaelf··on Hacked: commit to rails master on GitHub
I agree. If you exploit a site and then say "will you pay me for security audit?", then that's extortion.
michaelf··on Vortex radio waves could boost wireless capacity “infinitely”
That story was posted on April 1st in 2009, and isn't hosted on BBC's website. There isn't even a first name given for the researcher (only "Radio astronomer Dr. Venn"). Looks sketchy to me.

I can't find any other information about it, so I'm guessing its a hoax / April Fools joke.

michaelf··on I Miss Iraq. I Miss My Gun. I Miss My War. (2007)
One of the most thought provoking books I've ever read is "A Terrible Love of War" by James Hillman. This books explores the topic of the linked article from a Jungian point of view (motifs, archetypes, metaphors, mythology, etc...) which may turn off some people, but I found it expansive and fascinating. Highly recommended if the topic of the Esquire article was interesting to you.
michaelf··on Damn Cool Algorithms: Fountain Codes
I know there are lots of anti-patent folks on HN, but if anything deserves patent protection, digital fountains certainly do. This is useful, novel, and certainly non-obvious stuff. And really quite beautiful, IMHO.

Its always bothered me to read about inventors who discovered beautiful and amazing things, only to die penniless while powerful interests reaped all of the financial benefits. Hopefully the people who discovered these codes have been richly rewarded for their work.

michaelf··on Dropping a Magnet Through a Copper Pipe
This video made me curious about what a magnet factory would look like and I found a really great video that goes step by step through the process at a neodymium magnet manufacturer in Shanghai:

http://www.youtube.com/watch?v=BHuWloNGo6c

I was sort of hoping that the factory would look like that plexiglass prison in the X-Men movie that was designed to prevent Magneto from using his powers.

Alas, it's nothing like that, but it's an interesting video nonetheless.

michaelf··on Esther Dyson vs Bill Campbell: 2002 − 2012
> Particularly if those financial services are extractive in nature?

Could you elaborate on that sentence? What do you mean by "extractive"? In the context of natural resources, I take that word to imply that the resource is depleted (e.g. non-renewable). Do you have a difference sense in mind?

michaelf··on Stephen Fry: Steve Jobs
With regard to your suggestion that Apple is the offensive party in patent disputes, it's important to remember that the roles of offense and defense are reversed when you enter a court. This is because of the presumption of innocence.

When a murderer enters a courtroom, he's the defendant because he is presumed innocent. If the jury returns a guilty verdict, he becomes an offender, and the roles switch back. Following the verdict, it would be justified to view the prosecution as having defended society against the murderer who committed the offense. Prior to the verdict, the jury agrees to see things the other way around.

Likewise, Apple brings suit because, in its view, its patents should defend their innovations against copying. Again, because of the presumption of innocence, Samsung (or whoever) plays the role of defendant until a verdict is returned. Should Apple win their suit, then (under law) Samsung will be viewed as the offender, and Apple will have successfully defended itself against unlawful copying.

Which is a long way of saying that, if you believe that Samsung has unlawfully copied Apple's innovations, then it's entirely correct to view Apple as the defensive party in this patent mess.

michaelf··on Stephen Fry: Steve Jobs
“In most people’s vocabularies, design means veneer. It’s interior decorating. It’s the fabric of the curtains and the sofa. But to me, nothing could be further from the meaning of design. Design is the fundamental soul of a man-made creation that ends up expressing itself in successive outer layers of the product or service.” -- Steve Jobs

I desperately wish I was capable of seeing deeply into the meaning of that statement. I appreciate design, design thinking, human factors, etc..., but not nearly enough to understand it as the "fundamental soul," or how it (what?) expresses (how?) itself (who?).

If anyone here can provide a few words, or a pointer to some great communicator of design, I would very much appreciate it.

michaelf··on NeXT Research and Development "Alive and Well"
If you google several of the names from the article, you'll find that many of those engineers are still working on NeXT R&D, although under different product names (OS X and iOS). I wonder if any of them ever imagined that average janes and joes would be running NeXT workstations on their cell phones?
michaelf··on Intellectual Ventures on This American Life
> NO, ideas by themselves are meaningless. Take it from a guy who loves coming up with new ideas but isn't so good at the execution part

Maybe off topic, but this reminded me of a certain statement about poetry, by the poet WH Auden:

     For poetry makes nothing happen: it survives
     In the valley of its making where executives
     Would never want to tamper...
michaelf··on Pinboard.in service limited - FBI raided hosting company and pulled equpiment
Most likely, DigitalOne doesn't have support staff sleeping in hammocks at the colo. If you were an admin, logged in remotely (from switzerland, say, where DigitalOne is headquartered), and you saw a few racks of equipment go offline, would you:

  1. suspect that someone had walked away with 3 racks, or

  2. guess that some network hardware had gone bad?

A great place to start is "Applied Cryptography" by Bruce Schneier.

http://www.schneier.com/book-applied.html

Edit: Note, this really barely scratches the surface for building secure software. AC says how to apply cryptographic primitives correctly. It won't teach you how to avoid vulnerabilities specific to particular application domains (like CSS, SQL injection, etc...).

michaelf··on What happens to all the Asian-American overachievers when the test-taking ends?
Apologies for unfairly characterizing your statement. And I do agree that self-criticism in the black community is very typically met with hostility, and that "negative stereotypes" are perhaps too frequently glorified.

Regarding Cosby's remark about black families, I certainly understand his sentiment, but I agree it was somewhat simplistic. My father (and my grandparents) all had a pretty similar view to Cosby's. In the particular black neighborhood of Philadelphia where he was from, that type of conservatism was the norm. By the early '70s, several of his friends (along with him) had graduated from college and moved out of the cities into the predominantly white suburbs, and this cohort was for the most part extremely successful. Not everyone managed to get out of the city, though, and it wasn't because the ones who stayed behind were necessarily lazier or less hard working (though certainly many of them were). For the most part, the opportunities just ran out.

With that came, I think, a lot of the anti-assimilationist sentiment you see today. Yang mentions something similar in his article. When you work your ass off to excel in all of the culturally approved ways, but nonetheless you are passed-over for someone who worked half as hard as you, what are you to think? There's a whole generation of older black men who were stung in this way (and, as Yang mentions, a whole generation of Asian men in a similar, but largely better, situation). (And incidentally, I'm speaking about men instead of women because women face different challenges that I'm not qualified to discuss). In many ways, I don't think the situation is much different than what lead to hooliganism in the UK during the '80s.

So is the situation getting worse, better, or staying the same? Economically, it's a hard time for a lot of people. Kids graduating from college (of any race) are having a hard time finding jobs. Thirty-somethings who saved up to buy homes in 2005 are underwater. As global inequalities are being addressed, global competition is at its highest, particularly for jobs that previously would have been "entry-level". These are also the sort jobs which are most prone to nepotism.

Its hard to say what lessons will be drawn from this period. It seems entirely possible that many of the hardest working, most optimistic young black people of this generation will find themselves out of work, disillusioned, and wondering why they didn't just have more fun in high school (and passing that attitude on to their kids).

BTW, you might (should) say "Don't Asian Americans face the same economic difficulties? They're employed at the highest rate of any ethnic group in the country." This is true, of course, and there's a lot to say about that. But I think this post is already too long, and none of this has been particularly relevant to hacking, except maybe societal hacking. Maybe I can end with a question: why don't white kids, generally, work as hard as Asians, especially when they are being out-competed for valuable educational opportunities?

michaelf··on What happens to all the Asian-American overachievers when the test-taking ends?
Are you really suggesting that similar pieces haven't been written by African Americans? To my mind, the first several paragraphs were practically an homage to Ralph Ellison's "The Invisible Man." And Yang mentions Baldwin by name.

It seems to me that when those authors were writing (and earlier poets like Langston Hughes), the problems of assimilation and alienation were both more apparent (as in "WTF!!!") and at the same time more vague (as in "WTF???"). It demanded the attention of artists. It was the same era that included the most creative period in the development of Jazz and the Civil Rights Movement itself. I wonder if Asian-Americans find themselves at something of a similar juncture.

Ultimately, and unfortunately, I think the direction of African-American cultural identity ended up following in the direction Yang has set for himself. Yang says:

"The first step toward self-reform is to admit your deficiencies. Though my early adulthood has been a protracted education in them, I do not admit mine. I’m fine. It’s the rest of you who have a problem. Fuck all y’all."

He's obviously a bit tongue-in-cheek here, since earlier he wondered if his "defiance is just delusional, self-glorifying bullshit that artists have always told themselves to compensate for their poverty and powerlessness." I'm sure he's (ironically) comparing himself to African Americans (otherwise, why the black vernacular "Fuck all y'all"?).

Something he touches on but doesn't really flesh-out is the problem with defining yourself in the negative -- that is, defining yourself in terms of things you won't do because you've already established a social identity where you aren't that thing. When he says "I love this hard and unyielding part of myself more than any other reward the world has to offer a newly brightened and ingratiating demeanor, and I will bear any costs associated with it," I hear the the constant refrain in the African-American community to "keep it real", where what this really means is "don't range widely." And incidentally, this is also recognized by African-Americans -- see Dave Chappelle's sketch "When Keeping It Real Goes Wrong."

(btw, I'm an African American software engineer, so issues of race and culture are unavoidably fascinating to me)

michaelf··on A prophet will arise in CS
http://www.time.com/time/magazine/article/0,9171,824058,00.h...

I was surprised to find this old article from Time magazine back in 1956. It concerns the solution to Post's Problem, which the article describes quite succinctly as:

| The problem: Does each non-recursive, recursively enumerable set have the property that every recursively enumerable set is recursive in it? Post himself thought not, but it was not until young Friedberg came along that anyone had the proof.

Can you imagine a mass-market magazine publishing such a thing today? Perhaps it's unnecessary, since anyone interested in computability theory probably pays attention to blogs like Scott Aaronson's.

There's a quote from from Gödel later in the article that may also speak to the problem of popularization:

| "Unfortunately," says Czech-born Kurt Godel of the institute, "he wants to study medicine. An achievement like this at his age comes only once in a lifetime.

michaelf··on Russia's Crime of the Century
> ... this fact is neither very new nor very important to average Russian. Probably not even in top 10. There just are more urgent matters.

Out of curiosity, what are some of the top issues (of governance) that are important to the average Russian?

michaelf··on Dramatic escalation in Japan (Fukushima Nuke Plant)
Can you say how many lives have been saved because of the nuclear power plants over the past 30-40 years? This would include cleaner air in the meantime, costs which were saved and re-deployed to social welfare programs, cheaper power for individuals and businesses, meaning cheaper goods and more money available to feed and house love ones and spend on health care, and hell, even more money to spend on the expensive construction codes which undoubtably saved many thousands of lives during this tragedy.

I really can't say how many lives are enhanced or saved by simply being more efficient. And I can't predict the future, so neither do I know if nuclear power will ultimately be our downfall. But the question is far more complex than "society considers the loss of life acceptable." Society makes these choices to support and sustain better (and more numerous) lives.
