Tips for generating gRPC protocol buffers

Tips for generating gRPC protocol buffers

You can use the flag -I or -proto_path to specify the path to your protobuffer. The next flag specifies the language to compile to. The Go command is fairly well documented but the Node.js documents seem to only show how to dynamically load a proto file. This is how you generate a compiled file for use in your Node.js project.

GO

protoc --proto_path=$SRC_PATH --go_out=plugins=grpc:$DEST_PATH $SRC_PATH/service.proto

Node.js

protoc --proto_path=$SRC_PATH --js_out=import_style=commonjs,binary:$DEST_PATH --grpc_out=./ --plugin=protoc-gen-grpc=node_modules/grpc-tools/bin/grpc_node_plugin $SRC_PATH/service.proto

You obviously need the X11 development packages installed, X11proto in particular, but
here is the location of the keysyms header upstream copy if you can't bother
using the contents of your own hard drive. ;-P

Simple solution for using a WaitGroup with select{}
package main
import (
"fmt"
"sync"
"time"
)
func main() {
// Create a wait group of any size

Notes for Building Electron and VSCode in FreeBSD11
Copy all the files to the build directory.
Copy icudtl.dat to the build directory. (you can find it in the vscode downloads ex for linux).
chromium version in port is 52.0.2743.116.
This was built with FreeBSD 11.0-RELEASE-p1. If building with other versions probably need to change
the freebsd versions in diff files (ex. freebsd11 => freebsd10)
Installed
node => v6.9.1
npm => 3.9.2

Go RPC over TLS.You have to create the following keys: certs/client.crt, certs/client.key, certs/server.crt, certs/server.key. client.crt and server.crt should be signed with ca.crt, which should be concatenated to both client.crt and server.crt. It's easier to do with easy-rsa: http://openvpn.net/index.php/open-source/documentation/howto.html#pki
package main
import (
"crypto/tls"
"crypto/x509"
"log"
"net/rpc"
)
func main() {
