  Stuff Everyone Should Do (part 2): Coding Standards

Another thing that we did at Google that I thought was surprisingly effective and useful was strict coding standards. Before my time at Google, I was sure that coding standards were pointless. I had absolutely no doubt that they were the kind of thing that petty bureaucrats waste time writing and then use to hassle people who are actually productive. I was seriously wrong. At Google, I could look at any piece of code, anywhere in Google's codebase, and I could read it. The fact that I wa...

  Why doesn't Google copy successful startup ideas?

Google is definitely one of the largest players in Internet world. It owns the most popular search engine, mobile operating system and mapping service. It not only has huge user base but also is extremely rich. It can copy and create any product that is proven to be successful with its talent pool and money.

  Bill Gates : Ctrl+Alt+Del was a mistake

Microsoft chairman Bill Gates admitted that Ctrl+Alt+Del command was a mistake when he was in a fund raising campaign at Harvard University last week. This command was initially designed to reboot the system. David Rubenstein, the Harvard fund raising campaign chairman, asked Bill Gates : "Why when I turn on my software or computer do I need to have my three fingers to press control,alt and delete? Whose idea was that?" The answer given by Bill Gates is : "Basically because when you turn your co...

  Why would I learn C++11, having known C and C++?

I am a programmer in C and C++, although I don't stick to either language and write a mixture of the two. Sometimes having code in classes, possibly with operator overloading, or templates and the oh so great STL is obviously a better way. Sometimes use of a simple C function pointer is much much more readable and clear. So I find beauty and practicality in both languages. I don't want to get into the discussion of "If you mix them and compile with a C++ compiler, it's not a mix ...

  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...

  We need a programming language for the rest of us

Recently I took on the enormous task of learning Objective-C from the bottom up and I was struck by something I couldn’t shake: this is too hard. An experienced developer might scoff at me for saying that, but it’s true. I’ll be honest about my education, Calculus II was the most math I ever took, I have an advanced degree from Berkeley in Journalism. I am a proficient HTML/CSS developer and can glue enough javascript together to solve almost any problem that has presen...

  Testing like the TSA

When developers first discover the wonders of test-driven development, it’s like gaining entrance to a new and better world with less stress and insecurity. It truly is a wonderful experience well worth celebrating. But internalizing the benefits of testing is only the first step to enlightenment. Knowing what not to test is the harder part of the lesson. While as a beginner you shouldn’t worry much about what not to test on day one, you better start picking it up by day t...

  My ten development principles

After several years developing software, I have acquired a very a strong opinion on how software should be developed, I actually have come to the conclusion that everything boils down to 10 principles, that if well implemented, will make any software development successful. 1.- Customer first. “If we don’t take care of the customer… somebody else will.” Customer first means focusing from a customer perspective on real value for the product being developed,...
