    1. 「Fill down」功能 — 下拉式選單 → Edit Cells → Fill down


    2. 這時可以點擊「exclude」來取消選取

      稱為 exclude 想必可以 include 多個之故。

    1. All that I tried are not work for Chrome 91 on Windows 10. Two fingers horizontal swipe appears an arrow icon on left or right side start with white color. If you stop swiping then nothing happen. If you keep on then it turn to blue color then the backward/forward will happen. I guess this is the reason why the function can not be easily disabled because Google Chrome thinks user has the chance to stop it.

      Simply use Edge then this problem is gone.

    1. DataRobot gives you the choice to set constraints on the slope of feature effects.

    1. how effective the model is in terms of differentiating different instances


    2. Tip: You may like to explore a dataset using different targets. There’s a simple way to streamline that work: make a copy of the project (from the Manage Projects page) and re-run it with the second target.  

      弄 QT bug title parsing 時,就是想用這招來避免大量重複創建同一個 project. 用 duplicate project 的方式就可以變出新 project 以便更改 target. 我的觀念沒錯: project, target, dataset 三者綁在一起,改了就是另一個 project 了。

    1. I ran my own POC to determine if I could use the new image classification capabilities of DataRobot to classify images sourced from audio files.

      POC is Proof of concept

    1. The PowerShell command below lets you display the Windows Firewall state on the remote machine

      把 ComputerName 的部分拿掉就可以用在 local : Remote Invoke-Command -ComputerName [ComputerName] -ScriptBlock {netsh advfirewall show allprofiles} Local Invoke-Command -ScriptBlock {netsh advfirewall show allprofiles}

    1. Syntax : app.use(path, middleware function/s)

      這個講得最好,app.use(path, func) 就是給 path 指定一個 func 就對了。其中若 path 省略,則 app 收到所有 request 都 call 這個 func.

    1. Chromosomes selection

      用上了從 OneNote2001 "Kie Codes' Genetic Algorithms explained by Knapsack Problem" 學來的 Python builtin sorted() 以及 random.choices() 超爽的感覺。本來要從 nongranded array 裡取 20% 是有點挑戰,結果又好又簡單。

    2. 題目沒講清楚,輸入 string chrom 是猜測,key 則是答案 string. 比較兩者正確率傳回。

    1. chromosome encoding

      這是個練習題,很簡單,但做了就能徹底明白文章到此表達的意義。我的答案是 insert 9,10,11 行: s = "" for i in range(size): s += get_letter() 好棒好棒! Codingame 會記得我的答案 (但不會主動執行並通過)。

    2. 56 authorised characters

      26 alphabet * 2 大小寫 = 52 再加上 4 個符號。

    1. Copy Code (Ctrl+Shift+C)

      咦! ipython 也有這個功能嗎?

    2. Interactive REPL window

      哦! 又複習一遍, REPL 就是 monitor 、 console. 特別指的是類似 Node.js 的 interactive console 有個像 forth 一樣的 interpreter loop 把 JavaScript 變成 interpreter 環境。那就是 REPL。

    1. select Properties, select the Debug tab, then add -i to the Interpreter Arguments field.

      等於是 python -i , 目的是為了程式跑完以後查看結果。

    1. .PDB 檔中有什麼資料?

      可以用 "c:\Program Files (x86)\Windows Kits\10\Debuggers\x64\dbh.exe" dump .pdb 的內容 e.g. dbh.exe" -v proeforth.pdb x proeforth!Pro dbh.exe" -v proeforth.pdb x proeforth!KVM dbh.exe" -v proeforth.pdb x proeforth!user*

    1. python -m easy_install C:\Users\Prosserc\Downloads\QSTK-0.2.6-py2.7.egg

      it copy the .egg to site-package but not unzip the .egg because .egg can really run directly. The problem is data files in the .egg needs setuptools API to access and that's an extra effort besides I don't know how to know if my module is run from from .egg !! So, I want to install .egg means I want it to be unzipped to site-package. How?

    1. 請至「電腦桌面」→ 請點選「電腦」→ 「控制台」→ 請點選「地區及語言選項」→ 請點選「地區選項 選 中文(台灣)」「位置 選台灣」→ 再點選「進階」 選擇「中文(台灣)」→ 再按「確定」,重新啟動再登入E01即可。
    1. 富邦e01軟體安裝後出現亂碼?

      see my OneNote2020 "富邦e01 中文亂碼解法"

    1. JavaScrip array 超能力 "forEach" , "some" and "every"

      [1, 2, 3].some(function(el) {
      return el >= 2;
      12 OK 
      > <js>
      [1, 2, 3].every(function(el) {
      return el >= 2;
      1 OK 
    1. wcout.imbue(std::locale("chs"));// //設定語言區域為中國

      "cht" 則為台灣<br> c:\Users\8304018\Documents\GitHub\proeforth\Debug>proeforth.exe abc def 123 中文 台灣<br> Hello World!!<br>argv[0] = proeforth.exe<br> argv[1] = abc<br> argv[2] = def<br> argv[3] = 123<br> argv[4] = 中文<br> argv[5] = 台灣<br> c:\Users\8304018\Documents\GitHub\proeforth\Debug>chcp<br> Active code page: 950<br>

    1. PS C:\> pip install jupyter

      activate my venv 'playground' and do it, it works! Note! when activating 'playground' the current directory is not necessary at 'playground', I guess . . . YES!!

    2. PS C:\> python -m venv myenv PS C:\> myenv\Scripts\activate

      This does not CD to the myenv directory:

      <textarea cols=100 rows=8> Microsoft Windows [Version 10.0.18363.959] (c) 2019 Microsoft Corporation. All rights reserved. C:\Users\hcche>Documents\python_venvs\playground\Scripts\activate (playground) C:\Users\hcche> </textarea>
    1. use venv of python on windows & mac

      照這篇做,很簡單,開個 working directory "playground" and make it the current directory. 用 python -m venv playground 在當前 current directory 處建立 venv. 從此,.\script\activate.bat , .\script\deactivate.bat 就可以切換本 directory to be or not to be the activated environment 了。

    1. Go to the Project menu and choose Add Class.

      我竟然找不到,改用 search 的才找到。

    2. // 1. Use the Solution Explorer window to add/manage files // 2. Use the Team Explorer window to connect to source control // 3. Use the Output window to see build output and other messages // 4. Use the Error List window to view errors

      若找不到都在 view pull-down menu 裡面

    1. ProPath target_workspace

      workspace 的完整 URL "wtws://tkcourse/Workspace on 00-HC/"

    1. Pass NULL for a default checkout

      button 31 use NULL<br> button 41 use an Options structure

    1. The properties of the options will match the default checkout properties in Creo Parametric.

      初值照 default

    1. The called function should not populate this array with any ProValueData structures of type PRO_VALUE_TYPE_POINTER. */

      所調用的函數不應使用PRO_VALUE_TYPE_POINTER類型的任何ProValueData結構填充此數組。意思就是說,用ProValueData 但不是 PRO_VALUE_TYPE_POINTER。

      我做實驗發現奇怪現象,若 outputs 裡有個 block 的 type 是 arg1.value.type = PRO_VALUE_TYPE_POINTER; 整個 blok 就會被 skip! Caller 收不到這個 outputs[n] block.

    2. ProToolkitTaskExecute

      This function is a wrapper to call the actual ProTkdllFunction function

    3. Note:When done reading output_arguments, call ProArgumentProarrayFree to free the data.

      這就是說:用畢 output 值之後由 caller 負責 free 掉該 output argument array 的 memory. 這是對 toolkit caller 而言。 Web.Link caller 怎麼 free?

    1. typedef struct pro_server_conflicts* ProServerConflicts;

      很多 function 有 output ProServerConflicts conflict. 當它的 return ProError status 為 PRO_TK_CHECKOUT_CONFLICT 時,這個 output 才有意義,用 ProServerconflictsDescriptionGet() http://localhost:8800/Creo_3.0_Toolkit_Doc/protkdoc/api/5951.html 去查它的意義。

    1. ProValuedataWstringSet

      採用這類 function 的目的是 一、方便 二、到時可以用 ProArgumentProarrayFree() 一舉釋放乾淨。如果 ProArgument 在 static local 就用不著這個了。

    1. ProServerWorkspaceData* data /* (Out) The workspace data. */

      用完應該要 free 掉吧! ProServerworkspacedataFree() http://localhost:8800/Creo_3.0_Toolkit_Doc/protkdoc/api/5914.html 喔!不一定要,如果是在 local 宣告的 dynamic ProServerWorkspaceData 當然就不用 freee().

    1. static pfcArgValueCreateStringArgValue (string Value)

      it's a JavaScript normal string here but will be a wchar_t to the callee. Use CreateASCIIStringArgValue() for char string.

    2. static pfcArgValueCreateASCIIStringArgValue (string Value)

      use another function to pass a wchar_t * string

    3. CreateStringArgValue (string Value)

      it's wchar_t * string , according to my tests on ~\GitHub\proe\toolkit_training_Windchill\src\WcEx11.c

    1. Managing Application Arguments
    2. Task Based Application Libraries

      Read Toolkit manual's corresponding document page http://localhost:8800/Creo_3.0_Toolkit_Doc/protkdoc/manual0/Applilib.html#1

    3. pfcArgValue.discr

      This is the "ProValueDataType" in the union of "ProValueData" http://localhost:8800/Creo_3.0_Toolkit_Doc/protkdoc/api/provalue_h.html#ProValueData

    4. pfcDll.Unload()

      Just [STOP] and terminated. To remove the DLL from the auxiliary applications UI you need to click [delete] manually.

    5. pfcBaseSession.LoadProToolkitLegacyDll()


    1. typedef struct pro_argument
    2. Task Based Application Libraries
    3. ProValueData value

      This is a structure with type and an union that contains string that is a pointer only w/o the string itself.

    4. ProName label

      this is a wchar_t[200+] string with static memory

    1. Copies a file from local disk to a Windchill workspace;

      This function is for foreign files (none CAD files)

    2. The document which the copy will be attached to, "box7.prt" for example.

      指出誰是 primary 就表示 source_file 是它的 attachment.

    1. wchar_t* file

      Windchill 上只需檔名即可抓到 object (CAD 檔)

    2. top level object to checkout or download.

      same function for checkout and download

    3. Can be NULL.

      filename is enough, so we use NULL.

    1. conflicts

      [ ] There's a function to print the conflict thing , what's that? _

    1. The alias used by Creo Parametric to refer to the server


    2. ** data

      宣告 one star, called with &

    1. default_path

      wtpub://tkcourse or NULL

    2. shortcut_name_arr

      use NULL

    3. shortcut_path_arr

      use NULL

    4. NULL

      let's use this one

    5. allowing the user to select a directory.

      can access windchill , workspace, . . . etc

    1. p_file_name_array

      宣告 one *, call with &. so there's 2 stars.

    2. listing_option
