JDK 11 problem
JDK11網上好多人都有我呢個問題，就係11 refactor左好多class，如果用嘅library係jdk8到compiler就會有呢個問題。Netbeans進度太慢，最新嘅netbeans 9.0只支持jdk10仲要好多plugin都用唔到，原因係netbeans.org呢個domain仲未貢獻俾apache基金會。所以原先netbeans plugin啲lib用緊package org.netbeans仲未可以移到俾apache，呢單野唔知搞幾耐。
Hyper-V是Type 1的Hypervisor
Hyper-V是Type 1的Hypervisor, 當你安裝完它的時侯, 它會比所在的windows更加底層, Bootloader是會首先加載它然後由它去啓動完先的那一個windows, 所以之後的vm也和那個windows同級, 所以就算那個windows死機了, 其實Hyper-V是沒有死的, 在它上面運行的vm更加不會死.
