Surprising applications of math
The comments in the previous post touched on surprising applications of math, so I thought I’d expand this theme into it’s own post. Below I’ll give a couple general examples of surprising applications and then I’ll give a couple more personal applications I found surprising.Number theory has traditionally been the purest of pure mathematics. People study number theory for the joy of doing so, not to make money. At least that was largely true until the ...

What I learned from a month of blogging and 250k visits
Roughly a month ago, I decided to give blogging another try, in earnest. I put out an article most days and up to 3 per day when I was experimenting with new channels.It has been fascinating.That being said, this is not a post about blogging tactics. It’s about what the experience has taught me about startups.Find the customers first, then build for themIt took me a long time to understand YC’s motto that you should:Make something people want.The first time I heard that, ...

No support of $.browser in jQuery 1.9
Starting from jQuery 1.9, $.browser is no longer supported to detect the nrpwser type and version. The substitute is $.support. In the newer jQuery 2.x versions, IE 6/7/8 are also not supported. If users want to support IE 6/7/8, they must use jQuery 1.9. If you want to fully support IE and want to use jQuery 1.9 and jQuery 2.0, the official solution is: <!--[if lt IE 9]> <script src='jquery-1.9.0.js'></script> <![endif]--> <!--[if gte IE 9]> <script src=...

Why programmers are not paid in proportion to their productivity
The most productive programmers are orders of magnitude more productive than average programmers. But salaries usually fall within a fairly small range in any company. Even across the entire profession, salaries don’t vary that much. If some programmers are 10x more productive than others, why aren’t they paid 10x as much?Joel Spolsky gave a couple answers to this question in his most recent podcast. First, programmer productivity varies tremendously across the profession, but...

Full disk encryption is too good, says US intelligence agency
You might be shocked to learn this, but when a quivering-lipped Chloe from 24 cracks the encryption on a terrorist’s hard drive in 30 seconds, the TV show is faking it. “So what? It’s just a TV show.†Well, yes, but it turns out that real federal intelligence agencies, like the FBI, CIA, and NSA, also have a problem cracking encrypted hard disks — and according to a new research paper, this is a serious risk to national security.The study...

How to Think Creatively
I grew up hungry to do something creative, to set myself apart. I also believed creativity was magical and genetically encoded. As early as the age of 8, I began sampling the arts, one after another, to see if I'd inherited some gift.Eventually, I became a journalist. For many years, I told other people's stories. I was successful, but I rarely felt truly creative.The first hint I might have sold myself short came in the mid-1990s. In the course of writing a book called What Really Matters, Sear...

STOP WRITING GOOD CODE; START WRITING GOOD SOFTWARE
Good software trumps elaborate code. And unfortunately, you can’t usually have both. The real world has deadlines and ship dates. It’s a game of pick two:Ship on timeShip with elaborate codeShip with a fantastic productAlmost always, you should pick the first and the last when you’re building software applications for users (if you’re building API’s or open source libraries for other developers, then it’s a different story). Too often I have seen de...
