  How to check whether a struct implements an interface in GoLang

Unlike other programming languages like Java, when implementing an interface in GoLang, there is no syntax like below to explicit tell the relationship: type I interface { } type A struct implements I { } When looking at the code or running the code in GoLang, it might lead to a case one doesn't know whether a struct implements interface before trying to use it as some interface. According to GoLang spec, as long as a struct implements all functions of an interface, it is considered as having i...

  Create cron job on CentOS

These two days, I am building a website and deploying it on a VPS server which uses CentOS 5. I don't have cPanel or Plesk for my account, so I need to install and configure everything myself including Apache, PHP, MySQL and FTP server, also today's topic cron job. Since my website has a ranking algorithm to calculate the rankings of each link and update the ranking on database and I need to calculate the rankings every 5 minutes, so I think to use cron jobs. Here are what I have done which may ...

  Must read C++ book list

Every programmer should read some books to enhance their understanding about the language before the start to practice. But some of us often wonder what books we should read and in what order. Some books may not be suitable for beginners and some books may cover the similar topics. Here I summarize a C++ book list we should read.Stage 1"Essential C++" : It is short but powerful and it can enhance our understanding of C++'s features.This book is specifically designed to bring you up to speed in a...

  What drives the popularity of Node.js?

JavaScript is a programming language which can be used on both front end and back end. Its popularity should mainly be attributed to its power in front end side. While people seem not realize its power in back end until the appearance of Node.js.  Node.js is a server-side software system designed for writing scalable Internet applications, notably web servers. Programs are written on the server side in JavaScript, using event-driven, asynchronous...

  Who’s the winner: Python vs. Java, C/C++?

If there is one debate that never dies in the language community then it is this: Who’s the winner: Python Vs Java, C/C++. Obviously each has its own pros and cons, but in which language do the pros outnumber the cons or which language has better cons than others! For some it just comes down to familiarity, they like what they like!   The Numbers  But as far as the rest of the language world goes, the debate is still out there. By last count, Java, C and C++ were still winning. A...

  Socket programming tips in Solaris

I sponsored a topic in stackoverflow.com, and hoped the programmers can share the socket programming tips in different UNIX flavors. But unfortunately, the responders are few. So I can only share my socket programming tips in Solaris at here (the Chinese version can be found there): 1. Use the following link options: "-lresolv -lnsl -lsocket";2. Solaris doesn't provide socket options: SO_SNDTIMEO and SO_RCVTIMEO(Why does Solaris OS define SO_SNDTIMEO and SO_RCVTIMEO socket options...

  Accessing Reddit top posts using OAuth

Previously one can use the https://www.reddit.com/r/rprogramming/top.json API to access one subreddit's top posts. This API doesn't require any access token to fetch the data. However, this API may not work all the time. Reddit may block the API's request if it finds that you are using a script or some app which accesses the API now and then. For an app or script which needs to fetch the data routinely, what should we do? Reddit provides one method which can be used to fetch this kind of to...

  Exit main thread and keep other threads running in C

In C programming, if using return in main function, the whole process will terminate. To only let main thread gone, and keep other threads live, you can use thrd_exit in main function. Check following code: #include #include #include int print_thread(void *s) { thrd_detach(thrd_current()); for (size_t i = 0; i < 5; i++) { sleep(1); printf("i=%zu\n", i); } thrd_exit(0); } int main(void) { ...

  Understanding GoLang interface

If goroutine and channel are considered as the foundation for GoLang concurrency, interface would be the key for data types in GoLang. In practical Go programming, almost all data types are built/used around interfaces, interface is the core of GoLang data structures. Go is not a typical OOP language, it has no class and inheritance concept syntactically. But it doesn't mean that there cannot be polymorphism in GoLang. Because of interface, it achieves the same polymorphism effect as in C++, tho...

  Haxe: Another multiplatform language

There are two kinds of programmers: One is using different languages to solve problems, the other is inventing languages to solve problems. Haxe is an emerging open source programming language which is universal, powerful and easy-to-use. Some languages claimed they were multiplatform languages, such as Java, C# and ActionScript. They all are based on some platforms, Java has JVM, C# has .Net and ActionScript has Flash Player. While Haxe is a trule multiplatform language, it can be used to devel...
