  On Programming Deadlines

There are a lot of differences between programming, and programming professionally. The most notorious of which, is deadlines.DeadlinesWhen you're writing code for yourself, you can spend as much (or as little time) on it as you please--but when you're writing code for other people, you've got only a limited amount of time and resources to get the job done. In my experience, this typically leads to one of two situations:You've got to extend the deadline to finish the job properly.You've got to w...

  Is Java Set ordered or not?

“Is Java Set ordered or not? ” is the most popular question asked when you interview for a Java Developer position. Many fail to answer it, and I have to admit I was one of the many. I have known the answer is “Yes and No” for a long time. No. HashSet is not ordered. Yes.TreeSet is ordered. If the interviewer continues with some follow up questions, I’m not confident that I know the answer then. Why is TreeSet ordered? Are there any other ordered S...

  When to use STDERR instead of STDOUT

Every process is initialized with three open file descriptors, stdin, stdout, and stderr. stdin is an abstraction for accepting input (from the keyboard or from pipes) and stdout is an abstraction for giving output (to a file, to a pipe, to a console). That's a very simplified explanation but true nonetheless. Those three file descriptors are collectively called 'The Standard Streams'. Where does stderr come from? It's fairly straightforward to understand why stdin and stdout exist, however ...

  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...

  Why I love Common Lisp and hate Java

“Common what?” is a common reply I get when I mention Common Lisp. Perhaps rightly so, since Common Lisp is not all that common these days. Developed in the sixties, it is one of the oldest programming languages out there. In its heydays it was used mostly for Artificial Intelligence research at MIT, Stanford, Carnegie Mellon and the like, and therefore has a lingering association with AI. People not in AI shy away from Lisp. Common Lisp is a powerful and versatile program...

  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...

  Java Sequential IO Performance

Many applications record a series of events to file-based storage for later use.  This can be anything from logging and auditing, through to keeping a transaction redo log in an event sourced design or its close relative CQRS.  Java has a number of means by which a file can be sequentially written to, or read back again.  This article explores some of these mechanisms to understand their performance characteristics.  For the scope of this article I will be using pre-a...

  In praise of impractical programming

Although it’s become a cultural mainstay now, I still remember when I first saw that thick book — the one with the wizard on the cover — about a school for magic where wonders are easily conjured by those who know the proper spells. Of course, I’m talking about the Structure and Interpretation of Computer Programs. There was that other book with the spells, but the “Wizard Book” sincerely claimed to teach magic. For the past few years, I’ve been ...

  Why Every Professional Should Consider Blogging

I often argue that professionals should share their knowledge online via blogging. The catch is that virtually anything worthwhile in life takes time and effort, and blogging is not an exception to this statement. So before committing your energy to such an endeavor, you may rightfully stop and wonder what’s in it for you. Is blogging really worth it? In this article, I briefly illustrate some of the main benefits that directly derive from running a technical blog. 1. Blogging can impr...
