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-createdOne is creating worker when needed until the max number of workers createdIn this post, we will cover the demonstration of creating fixed number of workers pre-ahead. This approach is usually used when one knows there are lots of t...

Browsers allow JavaScript to read and write data on clipboard. Generally script should not modify user's clipboard to avoid impacting user expectation, but there are cases where this can indeed bring convenience to users. For example, for some code snippet, user can copy it to clipboard with one click instead of select and copy manually.There are three options for clipboard operation provided in JavaScript/browser:document.execCommand()Asynchronous Clipboard APIcopy and paste eventsThis post will briefly talk about these three options.document.execCommand()This is the early option for operatin...

When running lscpu command on Linux, it will list the CPU info on the machine. Take one example where there is one CPU with 2 cores and each core has two threads which indicates there are 4 cores available.Now let's see how many cores GoLang program would identify.From output, NumCPU and GOMAXPROCS both output 4 which is expected. How does go runtime get this info, does it get it through similar command like lscpu or /proc/cpuinfo? Let's dig more in GoLang's source code.In runtime/debug.go, it tells that this value is from the global variable ncpu which is set when process starts and...
