  How Chinese tech websites survive

As a tech site which aims to share knowledge and experience, content is its core value. To attract readers, it needs to produce valuable content and keep the originality of the content. When an article is published on a site, it should be a copyrighted property of that site or the original author while others should be very careful when considering to copy that article to their own site. They should generally avoid to copying the whole content of the article. However, in reality, this is no...

  Understanding the "this" keyword in JavaScript

Many people get tripped up by the this keyword in JavaScript. I think the confusion comes from people reasonably expecting this to work like “this” does in Java or the way people use “self” in Python. Although this is sometimes used to similar effect, it’s nothing like “this” in Java or other languages. And while it’s a little harder to understand, its behavior isn’t magic. In fact, this follows a relatively small set of simple rules. This...

  Let's talk about JSON.stringify()

JSON has been used in lots of places to exchange data among different services/systems. Nowadays all mainstream programming languages have built-in library support of JSON data parse and stringify. In this post, let's talk about JSON.stringify() in JavaScript. Let's first take a small example of Object conversion handling. There is a requirement to convert below object const todayILearn = { _id: 1, content: '今天学习 JSON.stringify()，我很开心！', ...

  Google Dart? Don’t bet against JavaScript

Procotols, programming languages and operating systems all compete in a constantly evolving software ecosystem. Out of that ecosystem only a few technologies truly have staying power and survive over the long term. An example? How about Ethernet? It’s been a survivor over the last thirty years despite existing in a constantly changing landscape that’s been populated with many worthy competitors. Ethernetâ€...

  A turing machine in 133 bytes of javascript

Multiply turing machine The fact it took me 20 lines of javascript to implement a nondeterministic turing machine simulatorlast week kept me up at night. All weekend. Too much code for something so simple and I kept having this gut feeling implementing a basic version shouldn’t take more than 140 bytes. Sunday afternoon I sat down for about an ...

  Backend-as-a-service?

As the list of *-as-a-service’s continues to grow, I thought I’d throw one into the mix. What about the idea of a backend-as-a-service (BaaS)? The recent surge of client side Javascript frameworks along with the attractiveness of simple RESTful APIs has created an environment where server-side interaction can be reduced to simply database interaction (including validation and some computation). But why stop there? What if the server-side of the equation was simply a RESTful, ...

  Interaction between JavaScript and Frameset

ou want to change more than one frame at a time? OK, well here is how to do make the trick work for you! The first thing you will need is a frameset to get you started. Again, I will use a frameset with two frames. Here is the code for the frameset page: <HTML> <HEAD> <TITLE>Frames Example 5</TITLE> </HEAD> <FRAMESET cols=\"20%,80%\"> <FRAME SRC=\"page1.htm\" name=\"left_frame\"> <FRAME SRC=\"page2.htm\" name=\"right_frame\"> </FRAMESET> <...

  Tricks with Direct Memory Access in Java

Java was initially designed as a safe managed environment. Nevertheless, Java HotSpot VM contains a “backdoor” that provides a number of low-level operations to manipulate memory and threads directly. This backdoor – sun.misc.Unsafe â€“ is widely used by JDK itself in packages like java.nio or java.util.concurrent. It is hard to imagine a Java developer that uses this backdoor in any regular development because this API is extremely dangerous...

  Start to work with rollup.js to pack JS files

rollup.js is a module bundler for JavaScript. It compiles small piece of JavaScript modules spreading in different files into a single larger standardized ES code file. This post will show some entry level usage for this library. Introduction Normally a bundler tool would compile a few small JavaScript files into a single JavaScript so that web browser can read, parse and render it properly. A bundler tool may be needed because of a few reasons: Some early stage browsers don't understand module...
