There's different ways to install: homebrew cask download java distribution from Oracle download java distribution from java.com And once the java version becomes outdated, there's different ways to upgrade too, which we will discuss below. Upgrade from brew cask homebrew cask doesn't offer the ability to upgrade a package, as brew cask upgrade <pkg-name> is not even available, see [details](https://github. https://www.liangzhou.dev/posts/2016-04-26-how-to-setup-github-pages-on-windows/ Tue, 26 Apr 2016 00:00:00 +0000 lzhoucs@gmail.com (Liang Zhou) https://www.liangzhou.dev/posts/2016-04-26-how-to-setup-github-pages-on-windows/ As we know that we can set up a local version of our Jekyll based GitHub Pages site to test changes locally before pushing to GitHub. The tricky thing is how to set it up on a Windows machine, given ruby and python as well as a few other components are not built-in to Windows, and getting those missing pieces installed and work together on Windows can be tricky. https://www.liangzhou.dev/posts/2016-04-24-es6-notes/ Sun, 24 Apr 2016 00:00:00 +0000 lzhoucs@gmail.com (Liang Zhou) https://www.liangzhou.dev/posts/2016-04-24-es6-notes/ ES6(a.k.a ES2015) has been around for some time. Although it is fully backward compatible with previous version of JavaScript - ES5 which has been around for decades, there's quite some new syntax and features introduced in ES6 that is exciting on one hand, but can easily get wrong on the other hand. This posts is my study notes on ES6. let for block scoping let defines block scope variables, which can be accessed in a nested scope just like var. https://www.liangzhou.dev/posts/2016-02-01-how-to-use-plunker/ Mon, 01 Feb 2016 00:00:00 +0000 lzhoucs@gmail.com (Liang Zhou) https://www.liangzhou.dev/posts/2016-02-01-how-to-use-plunker/ Plunker has been a great tool for developers to try out new ideas effectively, share code among communities. Compared to other popular tool such as JSFiddle and Codepen, I personally find Plunker excel in the following areas: Best support for angularjs. In fact Plunker itself is written in angularjs. Ability to create unlimited number of files. This makes trying out larger size of demos possible. https://www.liangzhou.dev/posts/2016-01-31-conditional-required/ Sun, 31 Jan 2016 00:00:00 +0000 lzhoucs@gmail.com (Liang Zhou) https://www.liangzhou.dev/posts/2016-01-31-conditional-required/ The Problem Angular does support the concept of conditional required through the built-in directive ng-required. And it works great in simple scenarios. Consider the following example where address2 is only required when address1 is not empty. Address1 : <input name="address1" type="text" ng-model="address1" /> Address2 : <input name="address2" type="text" ng-model="address2" ng-required="!address1" /> This can be done using ng-required as shown above. But what if we also want address2 to be 'not required' when address1 is empty? https://www.liangzhou.dev/posts/2016-01-04-newcomer/ Mon, 04 Jan 2016 00:00:00 +0000 lzhoucs@gmail.com (Liang Zhou) https://www.liangzhou.dev/posts/2016-01-04-newcomer/ I wanted to run a blog for quite a long time now. IMO, a blog a good way to: Keep track of knowledge. Communicate with people around the world. I will blog mainly on the technology I am interested, the projects I am working on, the knowledge and lessons I learned etc. Hopefully it will be fun. :) https://www.liangzhou.dev/pages/about/ Mon, 01 Jan 0001 00:00:00 +0000 lzhoucs@gmail.com (Liang Zhou) https://www.liangzhou.dev/pages/about/ I am a full-stack software engineer who: love JavaScript use Emacs love open source believe in BDD/TDD You can find me at: LinkedIn Profile GitHub Projects Stack OverFlow Account
