  Image lazy loading plugins on Github

Image lazy loading is a concept where images are getting loaded only when needed. It has been adopted in many web applications to reduce usage of bandwidth. When a web page is loaded in a web browser, not all the page elements would be visible in the view port, hence those resources(images, videos etc) don't need to be loaded.  Currently there are quite a few open source plugins on Github which can help achieve image lazy loading. Today we will introduce a few of them. Echo.js Echo.js is a ...

  The Go Pointer Magic

Go is a language with the pointer type, by which we can Pass pointer into a function and update value in-place. Add methods to a struct as (* T) A, which is different from (T) A(). However, the pointer is type-safe in Go, meaning that there are such restrictions of the pointer. Different types of pointers are unconvertible. Pointer type cannot be used for calculation. Pointer types cannot be compared, either == nor !=. No mutual assignment between different pointer-...

  20 bit operations programmers should know

While talking about bit operation, programmers usually think about its efficiency. In embedded programming and system core optimization, appropriate use of bit operations is always a fascinating. When finding a job, it will help you a lot if you use bit operations when writing codes. Mastering simple bit arithmetic skills is necessary. 1. Get maximum int value int getMaxInt(){           return (1 << 31) - 1;//...

  10 Tools Every Software Developer Should Use in 2018

The main problem I noticed about most programmers is that even though they know about latest software development tools, they never really spend significant time to learn them well. As a programmer, I always try to learn new tools and latest technologies. At the same time, I also look to improve my knowledge of tools which I have been using for many years. Whether you're a front-end developer, full-stack programmer or part of a DevOps team, you should familiarize yourself with the latest develop...

  How do Silicon Valley companies recruit

There are a lot of friends asking me about the basic flow of how Silicon Valley companies recruit engineers. As a candidate, I tried Facebook, Google, Yahoo, Oracle, and I received offer from all these companies. As an interviewer, I have interviewed no less than 300 people and I know about the process of recruitment. I write this article with the hope of inspiring people who want to go to Silicon Valley or who are preparing for interviews or who are in the design of the recruiting process...

  How to make select in WinSock exceed the 64-socket limit

When doing cross-platform network programming, the only API available on Windows that corresponds to the epoll/kevent style reactor event model is select. However, it has a limitation: the number of sockets passed into select cannot exceed FD_SETSIZE, which is set to 64. Therefore, select in Java’s NIO on Windows also has the same limit. Many services ported to Windows that use the reactor model face this constraint, which often gives the impression that server programs on Windows hav...

  When no need 3 handshakes in TCP?

Overview In the previous article titled Why TCP needs 3 handshakes simple answers were provided to the following three questions: Can application data be carried during the first handshake? Can application data be carried during the second handshake? Can application data be carried during the third handshake? Briefly, traditional TCP requires a three-way handshake to establish a connection, and during these three handshakes, only simple SYN and ACK packets are sent. From the perspective o...

  A journey to investigate a goroutine leakage case

In Go, creating goroutines is straightforward, but improper usage may result in a large number of goroutines unable to terminate, leading to resource leakage and memory leaks over time. The key to avoiding goroutine leaks is to manage the lifecycle of goroutines properly. By exporting runtime metrics and utilizing pprof, one can detect and resolve goroutine leakage issues. This post will go through one real case encountered by the author. The author maintains a service that connects to a targe...

  Processing Unicode Data in Python - A Primer to Understand Non-English Data Processing

Introduction: Currently we live in a world where people of diverse cultures/backgrounds use electronic devices to express their ideas, do their daily work that earns them their daily bread, and entertain themselves using content that is created using their own language and so on. Naturally, in order to make all these things happen, any computational instrument, be it a laptop or a desktop computer, or a smartphone, or something else, should be capable enough to serve all of these things in a man...

  Popular Golang JSON libraries evaluation

JSON (Javascript Object Notation), a prevailing data exchange format, is widely used in various platforms and languages. Golang, of course, will never miss the support for JSON. And with its own standard library, such as those interfaces like the REST API from the API Service in Kubernetes, it can easily process JSON. Although Go’s library works great, we can still seek those open-source JSON libs in Github to maximize our efficiency. Then the features, performance, applicability of these ...
