Pagination or continuous scrolling? It's a question
No matter in web page or mobile applications, information often can not be displayed on one page all alone, there needs some interactive modes which can expand page information: Pagination and Continuous Scrolling are very common interactive modes. Every day we may see them, they are so common that we do not even feel their presence, when browsing to the bottom of the page, we will see it. But it's difficult to choose which mode to use in design. Here we have a discussion on these two modes. Pag...

Vim anti-patterns
The benefits of getting to grips with Vim are immense in terms of editing speed and maintaining your “flow†when you’re on a roll, whether writing code, poetry, or prose, but because the learning curve is so steep for a text editor, it’s very easy to retain habits from your time learning the editor that stick with you well into mastery. Because Vim makes you so fast and fluent, it’s especially hard to root these out because you might not even notice them...

Here we talk about user experience distance with different examples: 1. Floating bubble layer When users need to delete one picture,they click on the "Delete" button, then the floating bubble layer appears to prompt the user to confirm the deletion, users only need to focus on the picture which reduces the visual burden, and also no need to mo...

Function Pointers in C are Underrated
The function pointer in C is, in my opinion, one of the most ignored gems of the language. It’s the kind of feature you rarely need, and then suddenly, one day, you find yourself in dire need of it, as evidenced by the real-life use-case below. If you don’t know what a function pointer is in the first place, here’s the meat of it: it gives you the ability to pass a function around like a normal variable. If you know Python / Ruby / Lisp, you might know it by the name...
An alternative way to parse URL in JavaScript
Normally when we need to process URL in JavaScript, we may use the location object. Then we can use location.hostname,location.href,location.port etc to get the information we need. In this post, we will parse an URL with an alternative way. We can use an URL to create a DOM object by calling document.createElement("a"). The complete code is: function parseURL(url) { var a = document.createElement('a'); a.href = url; return { source: url, protocol: a.protocol.replace(':',''), host: a.ho...

However, we will not discuss the similarities between them here, instead we will focus on the differences between them. ConcurrentHashMap and Hashtable are both thread safe.
