  Connect to SQLite using Go on Windows

In software development, it's often necessary to test and validate logic using a lightweight and easily manageable database system. SQLite, with its minimal setup and zero configuration requirements, is an excellent choice for such scenarios. Leveraging the simplicity and efficiency of SQLite for testing purposes can significantly streamline the development process. In this guide, we'll explore how to seamlessly connect to SQLite using Go on Windows, empowering developers to efficiently test the...

  Strict mode in JavaScript

1. Introduction In addition to normal mode, ECMAScript 5 includes the other mode : strict mode. It means it will make JavaScript codes execute in a more strict environment. The purposes to have strict mode are: Remove some unreasonable and parts of JavaScript syntax. Reduce some of the quirk behaviors. Remove some insecure parts of code execution. Make the execution environment more secure Improve interpret efficiency and increase the execution speed Build foundation for future JavaScript versi...

  A re-introduction to JavaScript

Introduction Why a re-introduction? Because JavaScript has a reasonable claim to being the world's most misunderstood programming language. While often derided as a toy, beneath its deceptive simplicity lie some powerful language features. 2005 saw the launch of a number of high-profile JavaScript applications, showing that deeper knowledge of this technology is an important skill for any web developer. It's useful to start with an idea of the language's history. JavaScript was created in 1...

  Go Error Best Practice

Being indulged in Go for quite a while and having implemented web-related programs, grpc interfaces and Operators, I seem to be an advanced beginner now. However, I am still a raw hand in production-environmental debugging, which is cumbersome if done by querying logs or error messages. Imagine the scenario that a full-text search is called when the specific location of the error log is missing. Then what happens when those error logs are not only in one place? Yes, my error logs can no longer h...

  PHP Sucks! But I Like It!

I read a rather interesting post yesterday called PHP: a fractal of bad design. It's been getting a lot of traffic among the PHP community lately because it's rather inflammatory. But to be honest, it does make a lot of really good points. It also makes a lot of mistakes and misses a bigger picture. A Few Mistakes The post makes quite a few mistakes and odd apples to oranges comparisons. Let me point out the major ones that I saw. No Debugger - PHP has xdebug which works quite...

  Mock Solutions for GoLang Unit Test

In Go development, Unit Test is inevitable. And it is essential to use Mock when writing Unit Tests. Mock can help test isolate the business logic it depends on, enabling it to compile, link, and run independently. Mock needs Stub. Stub function replaces the real business logic function, returns the required result, and assists the test. I involved the related test code for Controllers while writing Kubernetes Operator recently, and there would be mocks for GRPC and HT...

  One thought about JavaScript exception handle

Due to network, browser and cache issues, the JS executed in production may produce different results from the testing environments. Sometimes they may produce exceptions. Front-end developers may encounter this kind of exceptions frequently. But how to log and use them is seldomly considered by them. Actually, exception handling includes two steps : log and use. 1. Log Regarding to log error, this is relatively convenient, since in each browser, there is one interface called window.onerror. win...

  C Macro Tips and Tricks

Preprocessor vs Compiler To properly understand C macros, you must understand how a C program is compiled. In particular, you must understand the different things that happen in the preprocessor and in the compiler. The preprocessor runs first, as the name implies. It performs some simple textual manipulations, such as: Stripping comments. Resolving #include directives and replacing them with the contents of the included file. Evaluating #if and #ifdef directives. Evaluating #defin...

  HTML5 Web Worker

Web Worker is a JavaScript multithreading solution provided by HTML5. we can put some compute intensive codes into Web Worker and it will not hang the user interface. 1. How to use Web Worker Web Worker's basic mechanism is to use Worker to load a JavaScript file to create a new thread in JavaScript's main thread. It will not block other thread's execution and will provide a data exchange interface between main thread and new thread : postMessage() and onmessage. Let's look at an example: //work...
