  How small should a function be?

"The well-designed functions are often relatively small, large function design is often a mess or there is a lot of room for optimization."Maybe you think there is no need to discuss the size of functions, because the nature of the function design is cohesive, its size is only its manifestations. But it is necessary to discuss about the size of function because the statement above .First let's understand the concept of minimum code processing unit : a basic operation (assignment, comparison, etc...

  Overlap Detection

How does one detect when two strings overlap? In the case below, the four-letter suffix of string 1 matches the four-letter prefix of string 2. 1: "Fire at Will" 2: "William Riker is number one" Sometimes there are several matches; finding the longest is not always straight forward. 1: "Have some CoCo and CoCo" 2: "CoCo and CoCo is here." 2: "CoCo and CoCo is here." 2: "CoCo and CoCo is here." The naïve solution is to take...

  The "C is Efficient" Language Fallacy

I came across an article yesterday about programming languages, which hit on one of my major peeves, so I can't resist responding. The article is at greythumb.org, and it's called Programmer's rant: what should and should not be added to C/C++. It's a variation on the extremely common belief that C and C++ are the best languages to use when you need code to run fast. They're not. They're good at things that need to get very close to the hardware - not in the efficiency sense, but in the...

  PHP Multithreading – Faking It

PHP doesn’t really support multi-threading per se but there are ways to do “fake” multithreading. Here’s one I saw in the PHPClasses.org newsletter – Multi-thread Simulation. Note that this class is intedend for use on a webserver, as opposed to running PHP scripts from a command line (or similar). Check the end of this post for some alternatives you can try if you’re using PHP as a stand-alone scripting language. Now, I’m going to be lazy and just ...

  How to check which Ohai plugin hangs in chef client run

Ohai plugins are very important components in chef client which aims to provide resource management automation on a server. The data discovered by Ohai plugins are describing the current state of the server and they will be used to maintain the server in a desired state. Each Ohai plugin discovers a specific pierce of information about the server such as cpu, memory, middleware etc. However, there are rare occasions(well I am a bit optimistic here) someone may find that the chef client...

  Networking Terminologies

Portmaps sudo apt-get install -y portmap Portmap is a part of ONC RPC (Open Network Computing Remote Procedure) collection of software for implementing remote procedure calls between Computer Programs. It is widely used by NFS (Network File System) and NIS. Portmap is a server that converts RPC program number to DARPA protocol port number. It must be used in order to make RPC calls. Network Infomation Service (NIS) sudo apt-get install -y nis NIS is a client server directory service provi...

  Be careful about printing error as string in GoLang

In GoLang, we can format and produce string using fmt.Printf(), just like C, GoLang also supports format verbs like %s, %d which can be placeholder for different types of values. But please pay attention when printing error as string so that you will not fall into some trap. Let's first take an example code snippet and see what trap we are talking about. package main import "fmt" type A string func (a A) Error() string { return fmt.Sprintf("%s is an error", a) } func main() { a := A("hello...

  How I Learned to Program

Programming is, without a doubt, the most mentally rewarding thing I've ever done. Programming taught me that life should be fun, filled with creativity, and lived to the fullest. Programming taught me that anything is possible; I can do anything I want using only my mind. Programming also taught me that learning is fun. It showed me that the more you know, the more power you have. Programming showed me that a life filled with learning is a life worth living. Programming revealed to me wh...

  A mini post on GoLang context

In a GoLang web server, every request coming in will be handled by a goroutine. In the request handler, the logic may also need to create new goroutine to handle other tasks like RPC call. When the request is processed and response is returned, these goroutines created need to be exited so that no goroutine leak should happen. package main import ( "fmt" "log" "net/http" ) func main() { http.HandleFunc("/echo", func(w http.ResponseWriter, r *http.Request) { fmt.Println(&r) w.Write(...
