Universal App可以收工了?

Microsoft宣佈不玩Windows Phone了, Universal App意義何在? 加上Universal App有分C#和Javascript, C#是用Waml, 而Javascript就類似ElectronJS, 世界一早不同, 加上火不起來, 估計下一個要死的是Universal App了.

Coder Metrics – Way to measure coders

This book talk about how to measure coders. It stated three metrics: Skill, Response and Value. I think passion is also another important metric, but hard to be measure. If in Hong Kong, anti-blaming by project manager is also another important metric, there are too many skill-less managers in here, all their daily jobs are…

PowerApps做唔到cross account的calendar真係一種遺憾

PowerApps每一次Export package去另一個Tenant,就算SharePoint Site裏面連個Site名都一樣,佢都係無法自動化完成所有import流程,一定要人肉入去搞一次,好花時間。而個calendar基本上只可以read當前登入者嘅calendar,如果唔係就要經group calendar或sharepoint list,設計唔算完美。

Solved – The root cause why Netbeans can’t print colored text using latest Maven

Netbeans has bundled an old Maven, version 3.3.9, it can’t print out colored text to the output window. But when we switch to latest Maven 3.6.0, all color gone. I asked Netbeans guys, maven guys and jansi guys for help, but can’t get a solution. So i try to hack the maven code, i found…

Netbeans manually change color to green

Even the jansi library that built-in to maven 3.5.0 or above doesn’t work with netbeans, so we can’t output colored-text in Netbeans output window. But the “BUILD SUCCESS” word still in green. The reason is netbeans manually change the color to green.

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。

Easy easy to extend c# class

Love this book, a very easy way call “extension methods” can let you easily inject new method to existing classes (even you don’t have its source code). I tested it in windows with .net framework and mac .net core, both work correctly.

Simplest c# sample to call azure storage api

Finally called the azure storage api, stucked for one hour in library. There is a / in + “/{0}/\ncomp:list”, Account); Remember two things:1. If you are calling to azure management api, you need a cert. Read https://docs.microsoft.com/en-us/azure/cloud-services/cloud-services-certs-create and https://docs.microsoft.com/en-us/azure/cloud-services/cloud-services-configure-ssl-certificate-portal2. If you are calling azure storage api, you just need a key, no cert if needed.
