This is important, but it isn't exactly tech innovation. I think you got it backwards. Successful business with scale leads to technical innovations in many consumer-facing companies. Did Facebook in its early days have technical inn

The problem with 3) is not just wasted resources or company looking bad to outsiders. It also leads to rampant internal politics as people simply do everything in their power to win, or worse, to survive. Just to name a few common tricks: d

Can't agree more. Definition-theorem-proof type of textbooks is way too clean. They don't tell you how ideas came to be or why they mattered. In other words, it's hard for students to learn the intuitions behind the ideas. I

No, it's not the same as ELB. It's similar to Amazon's auto scaling feature that comes with AWS Auto Scaling Groups. There's a key difference, though. AWS ASG is threshold based: users define actions when specified metri

It's always the combination of conceptual learning and memorization when it comes to learn math. It's like performing a complex computation job once, and then caching the result for fast retrieval. Memorization is for efficiency:

Poetry is just an example. What really matters is to "feel" in a different language, be it reading poems, enjoying novels, laughing at jokes, watching movies, having an interesting conversation, interpreting other people's em

Not true. I'm an immigrant. I'm still learning English. If I need to decode an instruction manual, I can just use an English-to-My-Native-Language dictionary or even a translator. However, the real challenge is to intuitively unde

I don't know much about MongoDB, but it's true that Elasticsearch is a great NoSQL db with support of boolean search. Netflix has a number of use cases that use Elasticsearch as such NoSQL db: http://www.slideshare.net&

Well, I think you're into another extreme. Developing, yes. Poor? Maybe. Desperate? I'm not sure. At least our school days are full of fond memories. And my classmates seemed happy, and I was definitely happy. More importantly, we

Not really. I grew up in a developing country, where there were only public schools. And my school was by no means elite. Biographies of scientists were not part of curriculum either. It's really the culture. Parents did care about kid

This is sad. Very sad. The only explanation is that so many Americans are so spoiled by the nation's past success that they became so vain. I mean, kids are naturally inquisitive. Given the right nurturing, kids should love STEM. Heck,

Then the education system has a serious problem. Kids respond to incentives. Memorizing formulas would work only if students can get by homework and exams with rote memorization. We probably should learn from Russia/India/Korea&#x

I did realize the survivorship bias. It's shocking to me because if a good university like SJSU would have so many incompetent students, something is wrong with the K12 education system, or something is wrong with American families.

Did anyone take Thrun's basic stats course? Is it the same one that Udacity offered to the public? I'm bothered by this paragraph: "I think Thrun's elite background led him down a garden path. Any San Jose State professo
