Windows 10更新後遠端登入失敗 (CVE-2018-0886 的 CredSSP 更新)

執行 gpedit.msc
Computer Configuration->Administrative Templates->System->Credentials Delegation->Encryption Oracle Remediation->Enabled->vulnerable

執行 gpedit.msc
電腦設定 -> 系統管理範本 -> 系統 -> 認證委派 ->加密ORACLE補救措施->已啟用->易受攻擊

因為我是用英文版做業系統，所以抓英文版畫面

1.

輸入 gpedit.msc，執行

2. Computer Configuration->Administrative Templates->System->Credentials Delegation->Encryption Oracle Remediation 雙擊開啟

3. 設為「己啟用」（ Enable），並選擇「易受攻擊(vulnerable)」，然後按下 OK

Mac OSX 安裝 scriptcs 使用 Visual Studio Code 編輯

ScriptCS 是一個將 C# 語言撰寫的程式碼檔案(*.csx)編譯與執行的工具。

安裝Homebrew套件管理工具

Homebrew 的安裝很簡單，只要在終端機(Terminal)中輸入以下指令就能進行安裝:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

安裝 ScriptCS

brew install scriptcs

確認 scriptcs 安裝成功，查看 scriptcs 版本

安裝過程有看到版本號為 0.17.1

🍺  /usr/local/Cellar/mono/4.8.0.495: 1,604 files, 242.6M

🍺  /usr/local/Cellar/scriptcs/0.17.1: 38 files, 12.4

使用 scriptcs -version 查看版本號時顯示的是 Version: 0.0.0，可能是bug吧，使用很正常，沒遇到什麼特別的問題

scriptcs -version

/ __|/ __| '__| | '_ \| __// __/ __|

|___/\___|_|  |_| .__/ \__\\___|___/
                |_| Version: 0.0.0

建立 helloworld.csx

將以下內容存成 helloworld.csx

string s="Hello World!";
Console.WriteLine(s);

開啟終端機(Terminal)，在helloworld.csx 所在資料夾中執行以下命令

scriptcs helloworld.csx

如果成功在畫面上看到 "Hello World!" 的文字表示正常執行．

安裝 Vusual Studio Code

到官網Visual Studio Code下載安裝即可

安裝 Code Runner

Code Runner 可以設定多種程式語言的編譯和執行，因為我有時會寫 javascript，所以我安裝這套可以支援多種程式語言，如果只有要編譯執行 csx 的檔案，可以安裝 scriptcsRunner.

開啟 Visual Studio Code，在Extensions (Shift + Command + X)輸入「Code Runner 0.6.12」，找到後安裝它

設定scriptcs的編譯參數

到主選單 Code/Preferences/Settings 或 command + , 開啟設定在User Settings 加入 scriptcs $fileName。

{
    "code-runner.executorMap": {
        "csharp": "scriptcs $fileName"
    }
}

預設只有 scriptcs 的後面沒有帶檔名參數，在執行時會自動帶入「完整檔案路徑和檔名」，這樣反而執行都失敗。

測試Visual Studio Code執行csx 檔

使用 Visual studio code 開啟csx檔，然後選取要執行的程式碼，點右鍵彈出選單，選RUN Code

mac install .NET Core

install git
install node.js

npm install -g gulp bower
如果遇到 permission denied

要用

$ sudo chown -R $(whoami) ~/.npm

如果有 /usr/local/lib/node_modules 的權限錯誤

$ sudo chown -R $(whoami) /usr/local/lib/node_modules

如還有 /usr/local permissions

$ sudo chown -R $(whoami) /usr/local

其他方式參考

istall donet core 需要先安裝 openssl，使用 brew 安裝 openssl

$ brew update
$ brew install openssl
$ brew link --force openssl

install .NET Core

執行 dotnet restore 遇到錯誤



$ dotnet restore
Unhandled Exception: System.TypeInitializationException: The type initializer for 'Crypto' threw an exception. ---> System.TypeInitializationException: The type initializer for 'CryptoInitializer' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'System.Security.Cryptography.Native': The specified module could not be found.

執行以下這行，然後 dotnet restore 就能正常了

$ sudo install_name_tool -add_rpath /usr/local/opt/openssl/lib /usr/local/share/dotnet/shared/Microsoft.NETCore.App/1.0.0/System.Security.Cryptography.Native.dylib&nbsp

A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local.

Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include

Mac OS 抓取螢幕截圖

1. 整個螢幕截圖:

command + shift + 3 : 取得螢幕畫面，自動儲存在桌面。

control + command + shift + 3 : 取得螢幕畫面，儲存在剪貼簿中，當你要將擷取畫面放到其它應用程式中時使用此方式。

2. 部份區域截圖:

command + shift + 4 : 拖拉擷取螢幕畫面中的區域，自動儲存在桌面。

control + command + shift + 4 : 拖拉擷取螢幕畫面中的區域，自動儲存在剪貼簿。

3. 視窗截圖:

command + shift + 4 然後按「空白鍵」切換「區域截圖」或「視窗」，自動儲存在桌面。

control + command + shift + 4 然後按「空白鍵」切換「區域截圖」或「視窗」，自動儲存在剪貼簿。

修改預設截圖檔案名稱

開啟 Terminal 輸入以下命令

defaults write com.apple.screencapture name "wei_capture(date)"

killall SystemUIServer

ASP.NET MVC4 + Kendo UI - FileUpload Sample

使用 kendoui 同時上傳 model 與檔案

Javascript:

[HttpPost]
public ActionResult Upload([Bind(Include = "Title")]MyDataViewModel model)
{
    if (model == null) throw new Exception("Null");
    using (var transaction = _db.Database.BeginTransaction(IsolationLevel.Serializable))
    {
        var tempFileList = new List<MyFile>();
        try
        {
            model.CreateTime = DateTime.Now;
            model.CreateUser = Auth.CurrentId;
            _db.MyDataTable.Add(model);
            _db.SaveChanges();

            for (int i = 0; i < Request.Files.Count; i++)
            {
                HttpPostedFileBase file = Request.Files[i];
                var fileEntity=new MyFile(file);

                // do save file
                tempFileList.Add(fileEntity);
            }

            transaction.Commit();
            return new JsonResult()
            {
                Data = "Success",
                JsonRequestBehavior = JsonRequestBehavior.AllowGet
            };
        }
        catch (Exception ex)
        {
            foreach (var file in tempFileList)
            {
                // do remove file
            }
            transaction.Rollback();
            return new JsonResult()
            {
                Data = "Failure",
                JsonRequestBehavior = JsonRequestBehavior.AllowGet
            };
        }
    }
