  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 ...

  How to use xargs command in Linux

What is the xargs command? The xargs command constructs and executes commands provided through standard input. It takes input and converts it into command arguments for another command. This functionality is particularly useful in file management and can be combined with commands like rm, cp, mkdir, and others. Using the xargs command When used alone, the xargs command prompts the user to enter a text string and then passes it to the echo command. This example demonstrates the input provided an...

  Front-end Style Guides

We all know that feeling: some time after we launch a site, new designers and developers come in and make adjustments. They add styles that don’t fit with the content, use typefaces that make us cringe, or chuck in bloated code. But if we didn’t leave behind any documentation, we can’t really blame them for messing up our hard work. To counter this problem, graphic designers are often commissioned to produce style guides as part of a rebranding project. A style guide ...

  Basic Patterns for Everyday Programming

For most of you the patterns mentioned below should be nothing new. These are very basic stuff we slap into our code everyday and at times feels they are actually code smells than smart patterns. However, I've been doing some code reviewing lately and came across many code that lacks even these basic traits. So I thought of writing them down as a help for novice developers who would want to get a better grasp at these.These patterns are commonly applicable in most general purpose programming lan...

  Error handling in GoLang

Error handling is one of the must talked topics for any programming language. The program would be more reliable and stable if errors are handled properly and timely. Each programming language has its own way to handle error, this applies to GoLang as well. This post will discuss more about GoLang's error handling mechanism. Error handling Before talking more about GoLang's error handling, we can see how different programming languages are handling errors. C's error check The most direct way of ...

  Data as code

What is a good command line parser API? A good command line parser should consider below 5 aspects: Support convenient help information generation Support sub commands, for example, git has push,pull,commit sub commands. Support single character option, word option, flag option and option with parameter. Support default option, for example, if no -port is set, set it as 5037 Support usage model, for example, tar's -c and -x is mutually exclusive, they belong to different usage models. Here are...

  Resolving SVN error "Error validating server certificate for..."

When using SVN to connect secure server, the server needs to send its certificate to the client for verification. In some cases, the certificate sent by the server is not a trusted certificate, the client may choose to trust the certificate if the server is target server for sure.  But users may get "Error validating server certificate for 'https://...'" the next time when they try to connect to the same secure server even if they specified "p" the first time when they are prompted to accep...

  Prototypes and Object Orientation

David Chisnall takes a look at the two dominant paradigms in object-oriented languages (classes and prototypes) and discusses the strengths and weaknesses of each.Two terms are quite often confused when describing programming languages:class-based and object-oriented:Simula was the first class-based language. It provided classes (actually implemented using closures) as a means of encapsulating abstract data types.Smalltalk was the first object-oriented language. It provided a...

  The several flavors of random in Java

Random number generation is one of most basic features in any programming language. The basic utilization is always the same: generate a random number between 0 and 1. With such a simple resource at hand we sometimes overlook some interesting features. What do we learn from the books? The most obvious and maybe intuitive way to generate random numbers in Java is simply calling: java.lang.Math.random() Random generation is in the Math utility class with abs, pow, floor...
