  The Mature Programmer

1. The Mature Programmer The mature programmer manages their own time and productivity well. The MP knows that maintenance is as much work as the initial writing and code always takes longer than you think. The MP knows that any changes to code can introduce bugs, no matter how seemingly trivial. The MP knows that premature optimization is foolish and dangerous. The MP knows that sexy coding like writing big complex systems from scratch is rarely the best way to go. The MP does not get...

  Publish Your Go Package on pkg.go.dev

go.dev is a site where various resources for Go developers are shared, such as “Get Started”, Tutorial, Packages (pkg.go.dev), and all the official blogs. Among them, Packages is where I visit most, which allows free access to all the open-source Go packages submitted by communities including the native Golang packages. Thanks to all the contributors, I enjoy the great benefit, and sometimes I want to be a contributor myself. Let’s submit a “complete” package t...

  The Basics of jQuery

So, a while back I had an internal presentation at work about this topic. A few good friends in the community took a look at my slides, and they thought it would make a nice blog post because “there can’t be too many good posts about jQuery introduction and best-practices.” Whether this post is going to be good or not, is up to you but I’ll try to outline what jQuery is, and how you can start working with it. For most of you, this will just be a re-cap and probably...

  The Essence of Google Dart: Building Applications, Snapshots, Isolates

WÑ–th thousands of programming languages floating around, why is Google introducing Google Dart? What can it possibly add? The short answer: the Google Dart team wanted a language well suited to modern application development, both on the server and the (mobile) client. Some of Dart's features address problems that languages like Java or Javascript have long had. Dart's Snapshots resemble Smalltalk images, allowing (nearly) instant application startup and wi...

  Let's talk about JavaScript deep clone

In JavaScript, deep clone means creating a brand new object that includes all nested objects, with all properties being completely independent copies. This is different from shallow copying, which only copies the first-level properties, with nested objects being referenced rather than copied. There are multiple ways to perform deep copying in JavaScript, but the best one to use depends on the specific use case. Can use JSON.parse & JSON.stringify? ❌ JSON.parse(JSON.stringify(obj)) is a dep...

  Stop Designing Pages And Start Designing Flows

For designers, it’s easy to jump right into the design phase of a website before giving the user experience the consideration it deserves. Too often, we prematurely turn our focus to page design and information architecture, when we should focus on the user flows that need to be supported by our designs. It’s time to make the user flows a bigger priority in our design process. Design flows that are tied to clear objectives allow us to create a ...

  About C++ comma operator precedence

When learning programming language, we will always have one topic about the operator precedence. Since there are many operators can be used in one expression, there should be some rules regarding which operation can happen first so that the compiler or interpreter can handle them correctly. One rule of programming with expression is using as much as brackets as you can to avoid unexpected results. Here we refer one problem we see online about the comma operator in C++. The following program has ...

  So you want to write JavaScript for a living?

What do you need to know if you are interviewing for a job that involves Javascript development? What kind of expectations do employers have of candidates now that the state of client side development has been changed with the rise of asynchronous JavaScript and the often slick, supporting interfaces? These were questions I was asking myself after a friend pointed me to an interesting job posting over at Meebo that included some JavaScript puzzlers on logical operators, DOM odditi...

  The Problem With Client-Side Analytics

Client-side analytics is broken. The numbers produced by it are trivially spoofable by competitors and nefarious characters. Most websites use client-side analytics of one type or another and the only way to get numbers you can trust is to compare numbers from multiple providers and to take an average of the closest two.This post highlights the problem and proposes a partial solution that substantially mitigates the issues with minimal effort. Our proposed solution is simply to include a digital...
