  Hey, you may be happy to know these mottos about programming languages

Different programming are similar in helping people build staff work as people want them to. But they all have their own features which differentiate them from other programming languages. The language type may be different, for example Java is OOP, some may have different syntax. A programming motto usually can best describe the characteristic of the programming language. For example, "Write once Run everywhere" for Java. But today we are going to take a look at "unofficial mottos" about some p...

  String intern in Java

In Java, == is used to compare whether two objects have the same memory location, equals() is usually used to compare whether two objects have the same time and the same state.  When comparing two strings, normally we just want to know whether they have same content, so we can choose equals(). But since String comparison is so frequently needed, Java has worked on the String class to make == workable when comparing two String literals. The String class maintains a pool of emp...

  When and Where to Use Pointers in Go

When declaring variables in Go, we usually have two syntax options: In some scenarios, pointers; in others, reference; sometimes, either. It’s great to have choices, but it is also confusing sometimes as to which one in which scenario. To be more reasonable in choice-making, I started from pointers, walked through their natures, and summarized some rules in using them in Go. from unsplash, Jordan Ladikos Pointers Go has pointers. A pointer holds the memory address of a ...

  Address of a Java Object

In conventional java programming, you will never need address or location of a java object from memory. When you discuss about this in forums, the first question raised is why do you need to know the address of a java object? Its a valid question. But always, we reserve the right to experiment. Nothing is wrong in exploring uncharted areas.I thought of experimenting using a little known class from sun package. Unsafe is a class that belongs to sun.misc package. For some of you the package might ...

  The Web Is Wrong

The Analogies Are Wrong Originally, web pages were static documents, and web browsers were static document viewers; there was text, some formatting, and images—if you could pay for the bandwidth to serve them. Hyperlinks were the really big thing, because they were the main point of user interaction—but what a powerful thing they were, and still are. Then along came CGI and Java, and the web was transformed: all of a sudden, a web browser became a way to serve interactive co...

What should a ‘cache’ be? It means a lot of things, but to my mind the default programming type should be: “keep around expensive-to-generate bits of read-only data in case we need them again, or until the computer really needs that RAM for something else” I was writing a custom video editing program in Python (interesting choice of language for that problem) and I wanted to cache decoded frames; but I just wasn’t happy with the memory management of explici...

  When and How to Use the Go Channel

Go’s concise structure and powerful native library enable us to hit the ground running easily. It is more efficient than Java or Python when implementing the same functions, especially its concurrent programming, which is very handy and widely admired due to its goroutine and channel. goroutine and channel has much to dig into, and let’s start with channel, which I used to consider narrowly as a message queue to transfer data between gorouti...
