CSS DIV position analysis
When using CSS to set the position of DIV, we may often get confused with the 4 position properties : static, relative, absolute and fixed. If we don't understand them correctly, we may often get unexpected result. Here we make some analysis to them.The definitions of these 4 properties:static : The default position property. It has no position actually. The element will appear where it should be (top, bottom, left, right or z-index has no use here)relative : This one will position relati...
HTML above flash (transparency + z-index)
We have faced this problem many of the times. When we want to display some message on top of all layers on a page or use some feature like jQuery light boxes. Normally the flash file continues to shine through the page. No matter what you do with layering the dom elements using z-index.See the layering flash content problem definition here.Before this, people used to dodge this issue with some fixes like hiding the flash area completely and then showing a static image of...

Demo on creating worker pool in GoLang
A worker pool is a pool where a specified number of workers(usually goroutine) created and run to pick up tasks. This can allow multiple tasks to be ran at the same time while keeping the number of workers a fixed number to avoid overuse of resource in the program. There are usually two approaches of creating worker pool. One is with fixed number of workers pre-created One is creating worker when needed until the max number of workers created In this post, we will cover the demonstration of cr...

CSS Tools: Reset CSS
The goal of a reset stylesheet is to reduce browser inconsistencies in things like default line heights, margins and font sizes of headings, and so on. The general reasoning behind this was discussed in a May 2007 post, if you're interested. Reset styles quite often appear in CSS frameworks, and the original "meyerweb reset" found its way into Blueprint, among others. The reset styles given here are intentionally very generic. There isn't any default color or background set for the bod...

This behavior is often a source of confusion for many developers, especially those new to the language. In this article, we'll explore the difference between passing slices by value and by reference, and how it impacts the modification of slices within functions. Introduction In Go, slices are a fundamental data structure used to work with sequences of elements. They are essentiall...

A trick of building multithreaded application on Solaris
Firstly, Let’s see a simple multithreaded application: #include <stdio.h> #include <pthread.h> #include <errno.h> void *thread1_func(void *p_arg) { errno = 0; sleep(3); errno = 1; printf("%s exit, errno is %d\n", (char*)p_arg, errno); } void *thread2_func(void *p_arg) { errno = 0; sleep(5); printf("%s exit, errno is %d\n", (char*)p_arg, errno); } int main(void) { pthread_t t1, t2; ...
List of Web Safe Fonts
Here is the list of websafe fonts that I use in my own personal web development. Websafe (or "web safe", "safe for the web") fonts are supposedly fonts that are common among all versions of Windows, Mac, Linux, etc. Fonts that you expect everyone viewing your webpage to have. Please contact me if you know of any other web-safe fonts that should be added to this list. These font names are in typical font-family CSS format, in other words (first choice font), (second choice fon...
