  What? You tattooed code on your arm?

Since I'm seeing so many hits for this page, and since most of you are developers, I thought it might be worth trying to do a little blatant recruiting If you are an exceptional, passionate front end developer (HTML, CSS, JS) and you want to work in an awesome SCRUM team at a huge multinational company in the South of the Netherlands, please drop me a line (DM my Twitter account).There are also opportunities for developers (front and/or back end) and UNIX gurus at another brilliant com...

  Comparing Floating Point Numbers, 2012 Edition

We’ve finally reached the point in this series that I’ve been waiting for. In this post I am going to share the most crucial piece of floating-point math knowledge that I have. Here it is:[Floating-point] math is hard.You just won’t believe how vastly, hugely, mind-bogglingly hard it is. I mean, you may think it’s difficult to calculate when trains from Chicago and Los Angeles will collide, but that’s just peanuts to floating-point math.Seriously. Each ti...

  Why Programmers don’t have a High Social Status?

Up to date there is No single street name for a top programmer or computer scientist in any of the Top 20 most developed countries in the world during the last 60 years. There is no statue built in the center of a major city for a renown programmer or computer scientists. No “Presidential Medal” or “Congressional Gold Medal” has been awarded to a computer scientists or programmer. There is no nationally televised social reward ceremony for computer programmers and scie...

  Why Memorizing is Ineffective

The information-age has burst into life, creating a wake of social change. Young people are growing up faster and more sophisticated, as raw information, tailored-entertainment, and branded-marketing are streamed into their rooms. But this technological exposure has not necessarily made them savvier or more capable of handling tomorrow’s challenges.The debates in public education over “school-choice” and standardized testing have missed the far more important issue. The real c...

  Cache them if you can

“The fastest HTTP request is the one not made.” I always smile when I hear a web performance speaker say this. I forget who said it first, but I’ve heard it numerous times at conferences and meetups over the past few years. It’s true! Caching is critical for making web pages faster. I’ve written extensively about caching: Call to improve browser caching(lack of) Caching for iPhone Home Screen AppsRedirect caching deep diveMobile cache file sizesImproving app ...

  5 Reasons to Join a Startup After Graduating

After I wrote my last post, a surprising number of people emailed me asking why I decided to join a startup after graduating from Duke. Many of those I heard from face similar decisions today: either they are college seniors choosing between a big company and a startup, or they are recent graduates who work at a big company and are thinking about making the switch. What’s interesting is that most are already leaning towards the startup career path: it seems they just want someone to ...

  The Go Pointer Magic

Go is a language with the pointer type, by which we can Pass pointer into a function and update value in-place. Add methods to a struct as (* T) A, which is different from (T) A(). However, the pointer is type-safe in Go, meaning that there are such restrictions of the pointer. Different types of pointers are unconvertible. Pointer type cannot be used for calculation. Pointer types cannot be compared, either == nor !=. No mutual assignment between different pointer-...

  JavaScript is now a necessity

I've long looked at JavaScript as a second-class citizen in the programming world. Early on, it was the source of numerous security problems; it was a nice bit of glue to patch together HTML applications with a bit of styling, but nobody would use it for serious code; and so forth. Java, Ruby, Python, they were the languages for doing real work. But my attitude toward JavaScript has changed completely in the past few years. JavaScript has "grown up." I'm sure there are many JavaScript dev...

  Why TCP needs 3 handshakes

Prerequisite Knowledge First, let's look at the control bits and state machine of TCP, which form the basis for understanding the three-way handshake of TCP. TCP Packet Control Bits The control bits in the TCP packet header are used to control the status of the TCP connection and can indicate various control information such as connection establishment, termination, reset, etc. There are six common control bits: SYN (Synchronize Sequence Numbers): Requests to establish a connection (part of the...

  For Google CEO Larry Page, a Difficult Premiere Role

When Google Inc. co-founder Larry Page announced that he would take over as chief executive earlier this year, he promised that he would shake up the Internet search giant to speed up decision making. Instead, much of the shaking up has happened to the new CEO.Challenges have piled up for Mr. Page since he assumed his post in April. They include a broad U.S. antitrust probe of the company's practices; the settlement of a long-running criminal investigation into Google's adver...
