From the book Embedded Computing, it has a ISA chapter, below is the summary of “what is ISA” ISA helps compiler’s life easy. Hardware engineer often saving a few gates or some code, but that hurt the design of compiler ISA can both hide and expose key implementation details to the programmer or compiler Process […] 2018/05/22

I am building a small workflow using Microsoft flow to auto move the Nintex status email from my inbox to a SharePoint list. I found out some advantages of Flows than Nintex workflows.

寫Assembly用到Marco就試過N次，之前都係用到點就學到邊，無了解過佢嘅邊界，而家差唔多去到要為自己嘅assembler研發marco，所以要先睇下HLA嘅Marco大約可以做到啲乜。沙田圖書館係有唔少好書。 書中講左句： 啲人係用Assembler嘅Marco有幾勁黎判斷個assembler有幾勁，無錯，啲人確實係甘諗。以下就係關於assembler功能上嘅總結： Compile Time Operators. (E.g. : +-*/, <<, >> =, <>) Operator Precedence and Associativity (E.g. : !, -, div, mod) Compile Time Functions Type conversion Numeric functions Character-Classification functions (E.g. : isAlpha, isDigit, isSpace) String functions Symbol information (E.g. : @size, @define @typeName, @elements, @elementSize) Misc compile time functions (E.g. : @odd, […] 2018/05/17

Microsoft workflow foundation係幾勁嘅, 不過香港少人知。成套野包哂所有你要做一個完workflow engine嘅framework。Nintex係由WF做出黎就足以證明呢套野係work嘅！SharePoint個workflow engine係建基於workflow foundation上，了解WF同SharePoint workflow嘅分別從而推考到佢嘅好處同缺點就係學習SharePoint最堅實嘅方法，係一種深刻反醒佢本質嘅正確手法。 2018/05/13

In file .yo-rc.json, the value of “environment” is either “spo” or “onprem”, it identify your project is on-premises or sharepoint online. If you want to create extension, you have to use “spo” { “@microsoft/generator-sharepoint”: { “version”: “1.4.1”, “libraryName”: “quantr-express”, “libraryId”: “1a6a217f-6fb8-44b4-981f-35d0ebe7025b”, “environment”: “onprem” } } 2018/05/12

The reason nasm need to add the keyword “byte” in “adc byte [si], 0x12” is that in intel manual, m8 and m16 are same, so without this keyword the assembler don’t know what you want for. 2018/05/03
