完全痴線 – JTextComponent個setCaretPosition完來係錯
如果你放”abc\ndef”落JTextComponent, 佢會變Q左”abc\r\ndef”, 連帶影響埋setCaretPosition()會錯位，補救方法如下: 經過修正之後, 我個netbeans outline plugin回復正常了
The 5th Assembler dev meeting
Jenny has done SIB table, Kelvin is working on 66h 67h, Desmond is adding rest of the instructions. Thanks for Professor Ray visiting us and giving us advice.
x86 disassembler預研成功
x86 disassemble預研成功，感謝Rod Pemberton朋友在alt.lang.asm上面的幫忙，原來Intel instruction雖然係CISC但可以在未decode所有Byte之前把Instruction切割出來。還有，切割比我想像人來得簡單。我現在的問題就是，RISC的所謂固定長度指令好像不是傳說中所說的巨大優勢。
一本由讀computer science嘅人所寫嘅哲學書
我而家總結一下書中所帶出的哲學問題，所有讀computer science嘅人都應該花時間思考一下: 神。人。機械人。三者之關係 機械人的超限作用 人好明顯就是當機械人係奴隸 機械人之自我認同，自我意識 克隆人是機械人? 人是機械人?
Netbeans 11.0終於有plugin嘅library了
Netbeans自從貢獻左俾apache, maven central好耐無update, 由netbeans 9到netbeans 10都無library可用，以至8.1的plugin無從升級至netbeans 11. 今日check多次終於見到有11.0嘅lib了 https://mvnrepository.com/artifact/org.netbeans.api/org-netbeans-api-annotations-common

基本上掌握到JVM生成byte code
基本上掌握到JVM生成byte code，初步了解jvm的指令，能夠徒手用apache bcel生成class文件. 但感覺上jvm比.net core的vm重，所以先看看CLR才作最後決定。 題外話：基於jvm的語言除了java之外，沒一隻能夠有大的成功。
A new SharePoint Online error

一本唔錯的vSphere SDK書
書中是6.0，雖然和6.7有點距離，但不失為一個入門書。 最重的是有一個學習規劃。 以下是一個vSphere programmer應該要懂的topic: managing inventory managing host systems managing virtual machines, snapshots, and vmotion managing clusters and resource pools managing networks managing storage and datastores event and alarms performance monitoring task and scheduled task user and license administration extending VI client scrioting the VI sdk with jython, perl and powershell 必需把以上topic用sdk寫一次！！！

SharePoint的SPFX升級真的是千辛萬苦
由SPFx 1.0.0玩到昨天出的1.8.1，每一次升級framework都會遇到不同的麻煩。昨天Microsoft出了1.8.1，但我的Project還是用1.8.0，刪了node_module再npm i, 什麼也沒有做過就compile不到了，試了一回才發現最新版1.8.1剛出了，於是升級上去，結果又是什麼都沒有做，Project又變成可以compile到了。
不同project的不同webpart也是有機會撞ID的
寫太多webpart，終於遇到第一次撞WebPart ID，在兩個不同的spfx project裏webpart個ID重複，唯由手動改一改就可以deploy了
佛教 VS 西方心理學
書中見到，不知對不對：西方心理學認為潛意識不可受控，但佛教認為只要通過禪定就可以控制潛意識。之前見過一遍報導就係科學家檢測人腦，在你做決定之前已經知道到你會做什麼決定，代表潛意識有份參與決定。所以西方不認同潛意識可以受控，就代表人做決定根本不由己，這點我比較認同佛教多一點。 http://sa.ylib.com/MagArticle.aspx?Unit=featurearticles&id=2329
CPU由Soft core變Hard core的步驟

My understanding of the process for taking verilog and making it into an ASIC is something like:…
