  How can I teach a bright person, with no programming experience, how to program?

I usually prescribe the same sequence for anyone who wants to learn programming. It's very theoretical, but it lays a good foundation. It should take three or four months of fulltime study, but programming isn't something you learn overnight.If you can't get through this sequence, you're not going to be able to program, so you might as well give up now.Code, by Charles Petzold.The C Programming Language, K&RThe Structure and Interpretation of Computer Programs, Abelson and Sussman.My rule is...

  What Makes A Great Programmer?

I remember it like it was yesterday. It was the year 2000, Dr. Pargas was standing at the front of our data structures class talking about some data structure-y topic while an SSH session was projected on the wall in front of us. Someone asked a question, and he said something along the lines of "Well, if you want to be a real computer scientist you need to start using vi". I think he was smiling as he said it, and in hindsight his statement wasn't even slightly true, but being young and ...

  Introducing LocalDB, an improved SQL Express

Updated 2011-11-28: Added reference to the walkthrough of using LocalDB in Visual Studio 2010 and to the new LocalDB Installer. Updated 2011-11-02: Added reference to .NET Framework 4 support for LocalDB in the Q&A section. Introduction It gives me great pleasure to introduce a new version of SQL Express called SQL Express LocalDB. LocalDB is created specifically for developers. It is very easy to install and requires no management, yet it offers the same T-SQL language, programming surfac...

  Everything You Thought You Knew About Learning Is Wrong

Taking notes during class? Topic-focused study? A consistent learning environment? All are exactly opposite the best strategies for learning. Really, I recently had the good fortune to interview Robert Bjork, director of the UCLA Learning and Forgetting Lab, distinguished professor of psychology, and massively renowned expert on packing things in your brain in a way that keeps them from leaking out. And it turns out that everything I thought I knew about learning is wrong. Here’s wh...

You can click here and see what it looks like. It's an very useful functio...

  Efficiency of code execution

If you want to optimize your program codes, you need to find their Hotspot, i.e, the codes which are executed most frequently. If you can optimize this portion of codes a bit, you may gain much improvement of your code efficiency. Here I give you three examples about efficiency of code execution.1. PHP's Getter and Setter (From Reddit)This example a quite simple, you can skip it if you want.Consider the code below, we can find it's slower when we use Getter/Setter method to read a member variabl...

  printf("goodbye, Dennis");

Dennis Ritchie, a father of modern computing, died on October 8th, aged 70EVERY time you tap an iSomething, you are touching a little piece of Steve Jobs. His singular vision shaped the products Apple has conjured up, especially over the last 14 years, after Jobs returned to the helm of the company he had founded. Jobs's death in October resembled the passing of a major religious figure. But all of his technological miracles, along with a billion others sold by Apple's competitors, would be mere...

  Audio API in Android development

Mobile devices of the first generation were not capable of playing any sounds except monophonic ringtones. Today any smartphone platform supports playback, record and to some extent manipulation of digital sound, often up to CD quality.Android is no exception to that. Even older 1.5 devices can do a lot of things with digital audio. However, due to lack of guidance, a developer who is doing his first audio feature might miss some of the available API facilities, or might choose the approach that...

  Python Performance Tips, Part 1

To read the Zen of Python, type import this in your Python interpreter. A sharp reader new to Python will notice the word “interpreter”, and realize that Python is another scripting language. “It must be slow!” No question about it: Python program does not run as fast or efficiently as compiled languages. Even Python advocates will tell you performance is the area that Python is not good for. However, YouTube has proven Python is capable of serving 40 million videos...

  Learning Go

This year I'm going to try a new programming language - Go. I had this notion that compiled, type based languages are overly complex and reduces developer efficiency. However, after doing some reading about Go, it appeared to take a different path from the rest and felt like something worth trying. Acquainting a programming language is a journey. First few steps you take with it will define your perception about it. These first few steps went well for me with Go and it felt lik...
