Upgrade PostgreSQL 9.6.5 to 10.0 using Homebrew (macOS)
After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work.
The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0."
Database files have to be updated before starting the server, here are the steps that had to be followed:
# need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default
brew unlink postgresql
brew install postgresql@9.6
brew unlink postgresql@9.6
brew link postgresql

Aeotec Z-Wave Z-Stick Gen 5 UART protocol

Z-Stick Serial API

The Z-Stick does bi-directional communication over a UART. The connection speed is 115200, '8N1'. There are "requests" and "responses". The client software can make requests to the Z-Stick, and it will send responses. But it seems the Z-Stick can make requests of the client software too. I have yet to figure out the requests the Z-Stick sends to the client software.

Reverse tunnel. Connect to a public host somewhere and have it redirect all connections to your machine behind a NAT or firewall
# This enables a publicly available server to forward connections to your computer behind a NAT.
# So if you access http://xx.xx.xx.xx:8080/ on your browser, traffic is redirected to your machine behind a NAT.
# on your local host, type:
ssh -R xx.xx.xx.xx:8888:localhost:80 root@xx.xx.xx.xx
# now wait for your shell, and type:
socat TCP-LISTEN:8080,FORK TCP:127.0.0.1:8888
# This command outputs nothing, just keep it running. While you don't ^C, your tunnel is up and running!

Created April 16, 2013 09:27
AngularJS ngFocus and ngBlur directives - one way to get them before they get released. Before using, consider re-naming ngFocus and ngBlur to something that doesn't invade the ng namespace, e.g. replace all 'ngFocus' and 'ngBlur' strings with 'ngcFocus' and 'ngcBlur' (where c = cats/custom).
app.directive('ngFocus', ['$parse', function($parse) {
return function(scope, element, attr) {
var fn = $parse(attr['ngFocus']);
element.bind('focus', function(event) {
scope.$apply(function() {
fn(scope, {$event:event});
});
});
}
}]);

// Make our app module, its easier to do this in raw javascript
// and then put the rest of our app content (controllers etc)
// in their own coffeescript files.
//
// Your ng-app should include this module name, eg: <html ng-app="TodoApp">
angular.module('TodoApp', []);

AngularJS byte format filter
app.filter('bytes', function() {
return function(bytes, precision) {
if (isNaN(parseFloat(bytes)) || !isFinite(bytes)) return '-';
if (typeof precision === 'undefined') precision = 1;
var units = ['bytes', 'kB', 'MB', 'GB', 'TB', 'PB'],
number = Math.floor(Math.log(bytes) / Math.log(1024));
return (bytes / Math.pow(1024, Math.floor(number))).toFixed(precision) + ' ' + units[number];
}
});
