終於publish左第一個reactjs+typescript的UI component上npmjs

Publish當中最唔明就係點解要自己寫tsconfig同gulp人手張typescript同scss去transpile,呢一點同java好唔同,jar就係jar,唔會理你係邊到行,但nodejs個世界唔同,production同dev版本分別好大。你自己用npx create-react-app去創建新project,的確可以係local行,但就publish唔到上npmjs成功俾人用(可能係typescript同scss太煩)。而家個我個package可以同時俾reactjs同sharepoint spfx去用,可以build UI component library了。

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。

Powershell學習之旅 – Object Type

Powershell是一種typed的語言,和其它同種的語言比,它有一個我認為比較特別的地方,就是它支援不同的Object typ。Windows世界裏幾個大的Object家族它都支持: Common Object Model (COM) .Net Windows Management Instrumentation (WMI), 它是Management Object Format格式 ActiveX Data Objects Active Directory Services Interface (ADSI) XML Powershell是用adaptor的方式去和不同格式的object聯絡,此Topic沒有太多人有興趣所以書中並沒有提及。
