  Learn these technical skills within one day

It takes days and days reading books, practicing and involving in real project if you want to learn a programming language well. It's just like a marathon, you will get more if you can insist longer. During this long and boring period, there are always something you can learn within a short period of time, like within one day. These skills can bring your big satisfaction. Below are a list of technical skills which you can pick up within one single day, they are advocated by Jacob Jensen, a Googl...

  Pair Programming Stereotypes

Over the last couple of years, I’ve done a lot of pair programming. Pair programming inside my team, at customer sites, in coding dojos and in my open source projects. Pair programming is really a great and effective experience when performed by an pair of developers knowing how to pair program. Unfortunately, you cannot just put two developers in front of a single computer and expect them to perform perfectly from the start. Pair programming has to be learned. Both developers need to...

  Haskell’s effect on my C++: exploit the type system

Like most programmers, I was attracted to Scheme by the promise that it would make me a better programmer. I came to appreciate the functional style, but swapped to Haskell, a more developed language with a rapidly developing standard library. Unfortunately, for me, Haskell can’t yet replace C++ on a day to day basis, so I reluctantly spend my days tapping away at C++. So, were the promises true? has functional programming made me a better programmer? Better is a tough question,...

  Using MemoryMappedBuffer to handle large file in Java

When handling large files, it will largely affect the process speed while using traditional FileInputStream, FileOutputStream or RandomAccessFile since they trigger lots of read and write operations. In Java NIO, a new way of handling large file is introduced which is to use MmeoryMappedBuffer to create memory mapped file. Memory-mapped I/O uses the filesystem to establish a virtual memory mapping from user space directly to the applicable filesystem pages. With a memory-mapped file, you can pre...

  PHP to output string to client terminal

It is a common task to echo messages to the user using PHP. There are lots of ways where the message can be echoed to the client terminal(browser or console window) through PHP. These includes some well know debug methods like var_dump() and var_export() etc. In this post, we will show you some other methods shared by Laruence, one of the core members of PHP development team. 1. echo First comes with the most common one : echo. $str = "Hello PHP\n"; echo $str; 2. print Then comes another c...

  Some lovely software design quotes

  Every time when I read technical books, I like reading the quote of a famous person at the start of a chapter(if any), usually they are very interesting. Here is a collection of famous quotes. Life’s too short to build something nobody wants – Ash Maurya, Running Lean author Give someone a program, you frustrate them for a day; teach them how to program, you frustrate them for a lifetime. – David Leinweber There are two ways of constructing a software design: One way is...

  Load and execute JavaScript

When we load and execute JavaScript in a webpage, there are many points we need to care about because of its design and feature. There are two features about JavaScript execution in a browser: 1). The JavaScript codes will be executed immediately once loaded;2). When JavaScript codes are being executed, they will block the following contents (including page rendering and other resources downloading). So if there are multiple js files to be loaded, these codes will be executed sequentially. Since...

  Esmerelda's Imagination

An actress acquaintance of mine—let's call her Esmerelda—once said, "I can't imagine being anything except an actress." To which the retort was given, "You can't be much of an actress then, can you?"I was reminded of this exchange when someone said to me about Go, "I can't imagine programming in a language that doesn't have generics." My retort, unspoken this time, was, "You can't be much of a programmer, then, can you?"This is not an essay about generics (which are a fine...

  Engineer mindset in internet companies

This post tries to list down how we keep engineer mindset while doing development work. We engineers are the ones deliver the actual product by writing each and every line of the code, in order to deliver high quality and less buggy code, we should keep reminding ourselves what needs to be paid attention to during our daily development work.  So what is engineer mindset? Engineer mindset is that we should keep in mind that each and every line of code we write should serve the purpose well a...
