  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...

  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...

  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...

  Why I love Common Lisp and hate Java

“Common what?” is a common reply I get when I mention Common Lisp. Perhaps rightly so, since Common Lisp is not all that common these days. Developed in the sixties, it is one of the oldest programming languages out there. In its heydays it was used mostly for Artificial Intelligence research at MIT, Stanford, Carnegie Mellon and the like, and therefore has a lingering association with AI. People not in AI shy away from Lisp. Common Lisp is a powerful and versatile program...

  JavaScript-style object literals in PHP

The object literal notation in JavaScript looks like: var fido = {name: "Fido", barks: true}; or var fido = {}; fido.name = "Fido"; fido.barks = true; From assoc arrays to objects In PHP you would call that an associative array. $fido = array( 'name' => "Fido", 'barks' => true ); And you can easily make it an object too: $fido = (object)$fido; echo gettype($fido); // "object" Or if you want to start with a blank object and add stuff to it: $fido = (object)array(); or $fido...

  Understanding PGO in GoLang 1.20

Background The Go 1.20 version was officially released in February 2023, it introduced the PGO(Profile Guided Optimization) mechanism. The basic principle of PGO can be divided into the following two steps: First, profiling is performed on the program to collect data about the program's runtime and generate a profiling file. When compiling the program, enable the PGO option, and the compiler will optimize the program's performance based on the content in the .pgo file. When compiling a program...

  I hate cut-and-paste

Me, I blame the IDE's.Coding used to be hard. Not because programming itself was overly hard, but mostly because editors absolutely sucked. How much the typical development environment in the 70's and 80's sucked is hard to convey (except for a very lucky few, and those would have likely been using DEC and WANG gear). I got in on the tail end of the punch card era. Punching your own program is lots of fun. Once. And if you drop a deck you get to play with the sorter, which is also lots of fun (o...

  An open letter to those who want to start programming

First off, welcome to the fraternity. There aren’t too many people who want to create stuff and solve problems. You are a hacker. You are one of those who wants to do something interesting. “When you don’t create things, you become defined by your tastes rather than ability." – WhyTheLuckyStiff Take the words below with a pinch of salt. All these come from me – a bag-and-tag programmer. I love to get things working, rather than sit at something and over-o...

  Why does it take Task Manager longer to appear when you start it from the Ctrl+Alt+Del dialog?

Amit was curious why it takes longer for Task Manager to appear when you start it from the Ctrl+Alt+Del dialog compared to launching it from the taskbar. Well, you can see the reason right there on the screen: You're launching it the long way around. If you launch Task Manager from the taskbar, Explorer just launches taskmgr.exe via the usual Create­Process mechanism, and Task Manager launches under the same credentials on the same desktop. On the other hand, when you use the secure ...
