  How Computers Boot Up

The previous post described motherboards and the memory map in Intel computers to set the scene for the initial phases of boot. Booting is an involved, hacky, multi-stage affair – fun stuff. Here’s an outline of the process: An outline of the boot sequence Things start rolling when you press the power button on the computer (no! do tell!). Once the motherboard is powered up it initializes its own firmware – the chipset and other tidbits – and tries to ...

  Sequencing the Startup DNA on LinkedIn

What makes entrepreneurs different, and where do they come from? Are they born or taught? Are they unusually mobile in their careers? Does geography play a role? Do mentors and relationships matter?Numerous studies explore these questions by surveying hundreds of entrepreneurs. At LinkedIn, we take a different approach, on a different scale. By sifting through more than 120 million public profiles, we can analyze tens of thousands of startup founders’ [1]profiles – and find co...

  Objective-C Is The Language

My good friend Brent Simmons invokes a historical email from Linus Torvalds, about his disdain for C++C++ is a horrible language. It’s made more horrible by the fact that a lot of substandard programmers use it, to the point where it’s much much easier to generate total and utter crap with it.Brent affirms his support while paying homage to plain-old C:But I will admit to an enduring love of C. I still think of C not as C but as the language.I loved C. Emphasis on the past-tense. A...

  ARE YOU LIKE ME? OR DO YOU HAVE DISCIPLINE?

If you are anything like me, you've started more things than you have finished. We're innately curious about the things around us and inspired when we come across people who have mastered their trade. We see people create cool and beautiful things and think, "Man, that looks easy, if I put in a little time I can do that in no time." What follows is a few days or weeks of focused and dedicated learning. During this time we make some progress, but not much. In fact, the progress that we do ma...

  Will tablet revolution really come soon?

The famous Silicon Valley entrepreneur and academic Vivek Wadhwa said a few months ago that tablet revolution would come only if the price dropped below $100. According to The Wall Street Journal, the 4th largest PC manufacturer Acer seems to be the first one to eat crab. It plans to promote $88 Android tablet Acer Iconia B1. Does this indicate that the tablet revolution is coming? According to a person who knows the Acer tablet project, Acer Iconia B1 configuration will be similar to those of ...

  The Greatest Developer Fallacy Or The Wisest Words You’ll Ever Hear?

"I will learn it when I need it"! I've heard that phrase a lot over the years; it seems like a highly pragmatic attitude to foster when you're in an industry as fast-paced as software development. On some level it actually IS quite pragmatic, but on another level I am annoyed by the phrase. It has become a mantra for our whole industry which hasn't changed said industry for the better. The problem is this, in the guise of sounding like a wise and practical developer, people use it as an exc...

  The roots of Lisp

(I wrote this article to help myself understand exactly what McCarthy discovered. You don't need to know this stuff to program in Lisp, but it should be helpful to anyone who wants to understand the essence of Lisp-- both in the sense of its origins and its semantic core. The fact that it has such a core is one of Lisp's distinguishing features, and the reason why, unlike other languages, Lisp has dialects.)In 1960, John McCarthy published a remarkable paper in which he did for programming somet...

  Recursive class initialization in Java

When a Java class is referenced and initialized, it has to go through the loading and linking first. Once the loading and linking complete successfully. The class will be initialized. The static variables and constant variables will be initialized during this process. Once the class is initialized, it is ready for use. If when class A is initialized and it is referencing a class B, the class B will also get initialized. But what will happen if class B is referencing class A as well? This is call...

  CSS filter effects in action

CSS filter effects in action Ever since CSS filter effects landed in WebKit, I thought about theirs practical implementation. How will they fit with the current web design trends? At this time, my initial impressions are that the best way to showcase the power of CSS filters is something like an image gallery. With so many CSS filters to choose from, it will be fun to create image galleries in the future. Further in this article we’ll cre...
