  CSS Selector for Web Scraping

Creating a web scraper is no easy task. This is because it requires precision to identify the specific data points that we intend to collect for the end goal we are working towards.  Whether we are looking to create a marketing content database or analyze market trends, the last thing we need from our scraper is for it to return a lot of unnecessary data that will not help our cause. To avoid the inconvenience of going through huge amounts of data to get what we requested, it is crucial to ...

  Understand GoLang WaitGroup internals and how it works

Background Before getting into the main content, let me give a brief introduction to WaitGroup and its related background knowledge.

  One of the Best Bits of Programming Advice I ever Got

Years ago (early 1992), I attached myself to this crazy skunkworks project that was using this weird language called Smalltalk. "Object Oriented" was in its infancy as a "hot" item. High paid consultants. Lots of people laying claim to what this new object religion was all about. This was 5 years before Alan Kay would make the statement "I invented the term 'Object Oriented Programming' and this {Java and C++} is not what I had in mind."Shortly after hooking up with this whacky group with t...

  Most Pressed Keys and Programming Syntaxes

I switch between programming languages quite a bit; I often wondered what happens when having to deal with the different syntaxes, does the syntax allow you to be more expressive or faster at coding in one language or another. I dont really know about that; but what I do know what keys are pressed when writing with different programming languages. This might be something interesting for people who are deciding to select a programming language might look into, here is a post on the...

  The roots of Lisp

(I wrote this article to help myself understand exactly what McCarthy discovered. You don't need to know this stuff to program in Lisp, but it should be helpful to anyone who wants to understand the essence of Lisp-- both in the sense of its origins and its semantic core. The fact that it has such a core is one of Lisp's distinguishing features, and the reason why, unlike other languages, Lisp has dialects.)In 1960, John McCarthy published a remarkable paper in which he did for programming somet...

The WebSocket protocol has applications beyond plain vanilla web development.  I will explain how the protocol works, how to implement your own server and share some insights I had along the way. Before we get down and dirty, I will explain what I’ve been doing with it.

  Using JavaScript to operate clipboard

Browsers allow JavaScript to read and write data on clipboard. Generally script should not modify user's clipboard to avoid impacting user expectation, but there are cases where this can indeed bring convenience to users. For example, for some code snippet, user can copy it to clipboard with one click instead of select and copy manually. There are three options for clipboard operation provided in JavaScript/browser: document.execCommand() Asynchronous Clipboard API copy and paste events This p...

  The war with spam comment

Spam comments are annoying and notorious. They are either malicious data from hackers to exploit the loopholes of the site or advertisements posted by robots. These kinds of comments have their own features and patterns, if we are careful enough, we can find ways to block most of them although it's not so easy. To block the comment with malicious executable codes such as JavaScript, we should remember one rule : never trust user input. So wherever there are user inputs, we need to check the vali...
