[DDS]Vortex Opensplice 建議跳槽到 Cyclone DDS

> We, therefore, encourage the Vortex Opensplice open source community users to consider migrating to Cyclone DDS.

看到就準備要跳了喔 

https://github.com/ADLINK-IST/opensplice

For more than a decade, the Vortex Opensplice open source project helped to evangelise and successfully deploy the OMG Data Distribution Service Technology in thousands of industrial and academic projects worldwide. The Vortex Opensplice core team and the community have gained tremendous experience and know-how from these interactions.

Capitalizing on our lengthy experience developing data-centric middleware in real-time distributed systems the core team launched Cyclone DDS, a brand-new open source OMG DDS implementation. Cyclone DDS under the Eclipse foundation governance continues our mission to fuel innovation and serve a more diverse customer base. It is gaining momentum in many opensource frameworks and industrial contexts including ROS2 , Autoware etc. It also represents a genuinely open-source data distribution solution with full source code access and updates.

Buoyed by this success and adoptions, it became obvious that the focus of the core team and the community should now be Cyclone DDS. We, therefore, encourage the Vortex Opensplice open source community users to consider migrating to Cyclone DDS. The migration is straightforward when the ISO CPP V2 APIs are in use. For users that are building mission- and/or business-critical systems, ADLINK continues to support Vortex Opensplice Professional Edition and offers a commercially supported version with extra features and guarantees of support.

[arduino]Arduino IDE 2.0 強制設定為英文介面

 Arduino IDE 1.x 是以 Java 為基底。而 Arduino IDE 2.0 則是以 Javascript 為基底。

仔細的說，Arduino IDE 2.0 是以 node.js(後端) + Chromium(前端) 建構的 electron 架構為底。同樣使用 electron 為架構的有 vscode。(歷史的眼淚，開始是 github 用來做 atom 編輯器，在2022年6月8號，GitHub正式宣布在2022年12月15日關閉Atom，並存檔其儲存庫[by wiki]。)

好處是，近年來的 js 前端風潮，投入的人真的比較眾多且新鮮。進展也許真的會快很多，UI/UX 是真的不一樣。

現在對於 zh-tw 的翻譯還沒有完善，在我的電腦上，有些地方會使用到 zh-cn。如果像我這麼龜毛要處理的話，暴力處理就是強制使用 en，有兩個地方要處理。

1. 在 menu 上的中文要變英文，超暴力方法，執行檔目錄裡的 locales 目錄，底下除了 en-US.pak 之外的都殺掉。
2. 在 output 裡的 message 不要看到中文，在 C:\Users\<User>\.arduinoIDE 底下的 arduino-cli.yaml 內容第一行，加上 locale: en <換行>

這樣就可以全部都變英文。

[小知識]從 arduino 學到 NTP packet

 NTP 是網路對時的協定，在一般因為是作業系統自動處理，所以也不知到哪裡找資訊。

反而因為 arduino 這類 MCU 興起的關係，很多老協定的原始碼與 SPEC 就有了關鍵字可以深探與學習。

重點

* UDP 傳送，48 BYTE，UTC時間

兩段重點程式

```

unsigned long sendNTPpacket(IPAddress& address) {

    Serial.println("sending NTP packet...");

    // set all bytes in the buffer to 0

    memset(packetBuffer, 0, NTP_PACKET_SIZE);  //clear the buffer

    //Initialize values needed to form NTP request

    //(see URL above for details on the packets)

    packetBuffer[0]=0b11100011;   // LI, Version, Mode

    packetBuffer[1]=0;     // Stratum, or type of clock

    packetBuffer[2]=6;     // Polling Interval

    packetBuffer[3]=0xEC;  // Peer Clock Precision

    //8 bytes of zero for Root Delay & Root Dispersion

    packetBuffer[12]=49;

    packetBuffer[13]=0x4E;

    packetBuffer[14]=49;

    packetBuffer[15]=52;

    // all NTP fields have been given values, now

    // you can send a packet requesting a timestamp:

    udp.beginPacket(address, 123); //NTP requests are to port 123

    udp.write(packetBuffer, NTP_PACKET_SIZE); //send UDP request to NTP server

    udp.endPacket();

    }

```

```

unsigned long getUnixTime() {

    WiFi.hostByName(ntpServerName, timeServerIP);  //get a random server from the pool

    sendNTPpacket(timeServerIP);                   //send an NTP packet to a time server

    delay(1000);                                   // wait to see if a reply is available

    int cb=udp.parsePacket();                      //return bytes received

    unsigned long unix_time=0;

    if (!cb) {Serial.println("no packet yet");}

    else {  //received a packet, read the data from the buffer

        Serial.print("packet received, length=");

        Serial.println(cb);                        //=48

        udp.read(packetBuffer, NTP_PACKET_SIZE);  //read the packet into the buffer

        //the timestamp starts at byte 40 of the received packet and is four bytes,

        //or two words, long. First, esxtract the two words:

        unsigned long highWord=word(packetBuffer[40], packetBuffer[41]);

        unsigned long lowWord=word(packetBuffer[42], packetBuffer[43]);

        //combine the four bytes (two words) into a long integer

        //this is NTP time (seconds since Jan 1 1900):

        unsigned long secsSince1900=highWord << 16 | lowWord;

        Serial.print("Seconds since Jan 1 1900=" );

        Serial.println(secsSince1900);

        Serial.print("Unix time=");

        //Unix time starts on Jan 1 1970. In seconds, that's 2208988800:

        unix_time=secsSince1900 - 2208988800UL;

        Serial.print(F("Unix time stamp (seconds since 1970-01-01)="));

        Serial.println(unix_time); //print Unix time

        }  

    return unix_time; //return seconds since 1970-01-01

    }

```

[MSMQ]remote queue receive 遠端佇列接收

 快速說結論

在 Queue Server 端的設定 (Windows 10, Windows Server 2012R2 在 Workgroup 下測試通過)

然後 Guset 帳號不要開，Guset 帳號不要開，Guset 帳號不要開。

防火牆要注意一下。

就這樣。

其他更詳細的過程，有空再補充。

[powershell] 使用 Windows PowerShell ISE

 # Windows PowerShell ISE

在使用 Windows PowerShell ISE 遇到以下錯誤，簡單來說是因為權限的關係。

預設一般使用者無法執行 powershell script。

```

因為這個系統上已停用指令碼執行，所以無法載入 C:\x\00StartDevPCVM.ps1 檔案。如需詳細資訊，請參閱 about_Execution_Policies，網址為 https:/go.microsoft.com/fwlink/?LinkID=135170。

    + CategoryInfo          : SecurityError: (:) [], ParentContainsErrorRecordException

    + FullyQualifiedErrorId : UnauthorizedAccess

```

兩個解決方法，

(1)用 administrator 身份開啟 PowerShell 或 PowerShell ISE 來執行

(2)設定執行權限

設定執行權限，也是會遇到權限問題，所以也有兩個方法，

(1)用 administrator 身份開啟 PowerShell 或 PowerShell ISE 來執行「設定執行權限」指令

(2)只設定 CurrentUser 的執行權限

如果是使用方法(1)的話，以下指令可用。

`Set-ExecutionPolicy RemoteSigned`

如果是在使用者的 powershell 執行上面指令會出現

```

PS C:\x> Set-ExecutionPolicy RemoteSigned

Set-ExecutionPolicy : 拒絕存取登錄機碼 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell'。 若要變更預設 (Loca

lMachine) 領域的執行原則，請使用 [以系統管理員身分執行] 選項啟動 Windows PowerShell。若要變更目前使用者的執行原則，請執行 "Set-ExecutionPolicy -Scope CurrentUser"。

+ Set-ExecutionPolicy RemoteSigned

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : PermissionDenied: (:) [Set-ExecutionPolicy], UnauthorizedAccessException

    + FullyQualifiedErrorId : System.UnauthorizedAccessException,Microsoft.PowerShell.Commands.SetExecutionPolicyCommand

```

那就使用以下指令

`Set-ExecutionPolicy -S CurrentUser RemoteSigned`

## 參考指令

Set-ExecutionPolicy

Get-ExecutionPolicy

Get-ExecutionPolicy -List
