Synchronizing the Asynchronous - Controlling the flow in ascynchronous type of apps

You have certain process to run in sequence; for instance
1. Login into the system
2. Check if the user valid, user status is valid, user role is valid
3. Store for future references
4. Capture audit trail and set timing, menu etc
5. Finally, show correct page base on user role and preferences

This shall be ok in synchronize programming. However, for programming like javascript, js, etc., you may face issues such as null value on a certain process, invalid id, or pages, etc.

There is ways, 'easy' way, but there is no guarantee that the data you will be receiving is accurate or at the exact time you need it.

Example of easy way is using timeout, as shown below

setTimeout(() => {

resolve('success');

}, 100)

Yet, the above example may not resolve your issues entirely.

Another option that looks promising is using Promise. However, there is a drawback to it. Your program may continue waiting despite it is already completed. Although it is a promise, within promise is still asynchronous program run.

return new Promise( (resolve, reject) => {

if (user) {

console.log("getUserProfile() - Success getting user in "

+ JSON.stringify(user) );

resolve(user);

} else {

this.showError('Access Denied! Invalid User Access');

reject('Access Denied! Invalid User Access');

}

});

Take for example the above code. The console may run after resolve(user) as the JSON.stringify may take few seconds than just return resolve value.

So, what is the best solution. Actually, there are no better solutions. What I did was,
1. Rewrite the code and logic and ensure all setting was done prior to user validation and page movement.
2. You can use Reducer or Promise-Sequential

You may refer here:

1. https://blog.risingstack.com/node-hero-async-programming-in-node-js/
2. https://forum.ionicframework.com/t/how-can-i-use-promise/40469/3
3. https://www.promisejs.org/
4. https://javebratt.com/wtf-promise/
5. http://coenraets.org/blog/2016/02/angular2-ionic2-data-services-promises-observables/https://stackoverflow.com/questions/47767654/ionic-3-typescript-promise

For me, I'm using the latter (with timeout) as the former implementation is a bit complicated compared to the latter.

Here how I resolve the problem:

var sequential = require('promise-sequential');

var array = [this.getUserProfile(),this.validateUser()];

sequential(array.map((item) => {

return function(previousResponse, responses, count) {

return new Promise(resolve => {

setTimeout(() => {

resolve('success');

}, 100)

})

}

}))

.then(res => {

this.doLogin()

})

.catch(err => {

console.log('loginWithPromise(): ' + err );

this.showError(err);

})

wallawei!!! Hope it helps :)

Cannot parse JSON-encoded object value

I'm using Loopback, a node.js API framework which helps you to develop RESTful API very easy and fast. It reduces the programming/coding require and allow you to deploy your API within days.

However, things may not be as easy you can think of. The documentation given is still lack of information and there are not many solutions that can help you to solve your problem. One of it is Cannot parse JSON-encoded object value issue.

The error message you will get as example below

error": {

"statusCode": 400,

"name": "Error",

"message": "Cannot parse JSON-encoded object value.",

"stack": "Error: Cannot parse JSON-encoded object value. at Object.fromSloppyValue (D:\Project\loopback\touchpoint\node_modules\strong-remoting\lib\types\object.js:34:19) at HttpContext.buildArgs (D:\Project\loopback\touchpoint\node_modules\strong-remoting\lib\http-context.js:193:22) at new HttpContext (D:\Project\loopback\touchpoint\node_modules\strong-remoting\lib\http-context.js:59:20) at restStaticMethodHandler (D:\Project\loopback\touchpoint\node_modules\strong-remoting\lib\rest-adapter.js:485:15) at Layer.handle [as handle_request] (D:\Project\loopback\touchpoint\node_modules\express\lib\router\layer.js:95:5) at next (D:\Project\loopback\touchpoint\node_modules\express\lib\router\route.js:137:13) at Route.dispatch (D:\Project\loopback\touchpoint\node_modules\express\lib\router\route.js:112:3) at Layer.handle [as handle_request] (D:\Project\loopback\touchpoint\node_modules\express\lib\router\layer.js:95:5) at D:\Project\loopback\touchpoint\node_modules\express\lib\router\index.js:281:22 at Function.process_params (D:\Project\loopback\touchpoint\node_modules\express\lib\router\index.js:335:12) at next (D:\Project\loopback\touchpoint\node_modules\express\lib\router\index.js:275:10) at Function.handle (D:\Project\loopback\touchpoint\node_modules\express\lib\router\index.js:174:3) at router (D:\Project\loopback\touchpoint\node_modules\express\lib\router\index.js:47:12) at Layer.handle [as handle_request] (D:\Project\loopback\touchpoint\node_modules\express\lib\router\layer.js:95:5) at trim_prefix (D:\Project\loopback\touchpoint\node_modules\express\lib\router\index.js:317:13) at D:\Project\loopback\touchpoint\node_modules\express\lib\router\index.js:284:7"

You can google it but the solution was not helpful enough to guide you. Sometimes, when you used its pre-default apps (coming together when you setup your loopback apps) known as swagger (Loopback API Explorer), the url and parameter used seem work as it meant to be. The problem only occurs when you try to call it from 3rd party apps such as ARC (Advanced Rest Client, POSTMAN, IMSONIA) or from your program, the above error occurs.

How to solve this?

1. Ensure that you run and test your parameter passing which should be in JSON format is valid. You may use online such as Jsonlint or any JSON validator available.
2. If it is valid, then, ensure that all key and value is in open and close double quote - "key": "value". Do not use single quote 'key': 'value'
3. Finally, if the above two is correct, encode some of your parameter; for instance, '%' shall be encoded to '%25'. Use online encoder to help you such as https://www.urlencoder.org/

The above solution only applicable if you implement method through http GET, POST, PATCH, etc request. It may not be applicable for other REST calling method.

Set the display to center using Ionic

If you are developing apps focusing only on mobile, you may not be facing display issue as the user won't be able to see gaps or alignment problem. However, if you are developing apps that required to run on multiple platforms including web and mobile, aligning your display may cause a problem.

You will spend lots of time to configure your .css (or .scss) and when you thought you solved the problem on mobile, it shows differently on web.

I too faced such difficulties and finally found a way to solve it. I'm using ion-card and ion-list together.

here are snapshot of the code

<ion-card-content style="justify-content: center; margin-left: 0px; margin-right:

0px;background-color: #000000;">

<ion-card-title style="color: #fcfa87">

Center content <br> Working together

</ion-card-title>

<ion-list no-lines style="justify-content: center; margin-left: 0px;

margin-right: 0px; background-color: #030303;">

<ion-item style="background-color: #f1f7d6;">

<ion-label floating class="item item-input">Username</ion-label>

<ion-input type="text" name="username" class="input-label"></ion-input>

</ion-item>

and of course you need to configure your .scss too

snapshot of the code

.displayed {

display: block;

margin-left: auto;

margin-right: auto;

}

.card{

width:100%;

margin: auto;

}

the first (.displayed) shall be call by your ion-content tags and the .card is automatically set the card to be 100% width depending on your screen size

and it shall be displaying nicely on any screen as shown below

On web browser

On iPhone 7

For complete source code, you can download from my github.

All the best coding :)

Developing Microservices Using Orleans by Microsoft

I am new to Microservices although it has been a while in software engineering world. Luckily Microsoft (am not marketing them) has done a pretty good job in explaining the detail.

Take a look if you guys which to understand in detail.

Microservices offer great benefits but also raise huge new challenges. Microservice architecture patterns are fundamental pillars when creating a microservice-based application. [more]

And as part of their initiative (and of course to boost their .NET platform), they too develop a framework to support the implementation of microservices. Have time to read here.

Tableau - The user could not be added because you do not have access to the domain specified.

You may get the following error when you try to add new user. You have try may solutions as listed in Tableau:

https://community.tableau.com/thread/193590

https://community.tableau.com/thread/240964

Even you have file a case at Tableau Support and received respond from them. I received the following from Tableau Support:

Thank you for contacting Tableau Technical Support. My name is Henk, and I will be assisting with this case.

I have investigated the reported issue and I do have some steps below that should resolve the permissions issues on Tableau Server. We suggest consulting with your Active directory administrator to make sure the Tableau Server Run As User account has been granted permission to has access to query the Active Directory. If having the access capability, please follow the steps below re-entering the Run As User password and start Tableau Server.

• Try stopping TABLEAU Server, re-enter the Run As User password and start Tableau Server

1. Open Command Prompt and run as administrator, navigate to the “bin” folder located in the Tableau Server directory. For example if Tableau Server is installed in the default location, the directory will be: C:\Program Files\Tableau\Tableau Server\\bin 2. Type the following command to stop Tableau Server: tabadmin stop 3. From the start menu, type "Configure Tableau Server", and right click the program to open it as a Window Administrator.

4. Type the Run As user password and click "Ok" to save.

5. Type the following command to start Tableau Server: tabadmin start

Additional information on how to add Active Directory users can be found in the following links:

Add Users to a Site

http://onlinehelp.tableau.com/current/server/en-us/sites_addusers.htm

I believe the above information will resolve this issue. If the information provided does not resolve the issue, please let me know by responding with the additional information requested below and a few details regarding why the solution above did not resolve the issue.

1.            What issues are still occurring?

2.            Did the steps not resolve the issue?

3.            Is this an issue with all users or just a specific Active Directory user?

We may send a survey to confirm that the case has been fully resolved.

We appreciate any feedback on this issue as well as the general Tableau Technical Support experience.

Thank you for being a valued Tableau Software customer!

Please find your case summary below. To update this case via email, please reply to this message.

Sincerely,

Henk

Tech Support

Tableau Software

After try all the above, you still get the same result and thought of re-install your tableau server. Before you do that, let me give you another solutions:
1. Please make sure the username used to manage the tableau server (start, stop, restart) is register in the same domain as other user (in your Active Directory, LDAP server, or any authentication method used excluding local authentication)
2. If no. 1 ok, then ensure that the user has administrator privileges and has granted by your domain authenticator (in my case is Active Directory)
3. Open you Tableau Server Config (for Windows Start Menu > Tableau > Config Tableau Server).
4. In the window pop-up, make sure the username and password entered is the same username/password register in the Active Directory.
5. Restart your tableau server. Opps.. I recommended that you stop your tableau server first. :)

And it shall solve your problem.

p/s: it took me 2 days to figure out.

Get start with ionic framework

When I first developed apps using ionic, not many resources over the net will provide good explanation on it. I've found one and it is very easy to understand.

Here is the structure of ionic framework after it successfully execute ionic start command; for example 

ionic start myfirst blank --v2

>> ionic start [your_apps_name] [template] [ionic_framework_version]

the command will create a new folder (myfirst) and construct the following structures

├── hooks // custom cordova hooks to execute on specific commands 

├── platforms // iOS/Android specific builds will reside here 

├── plugins // where your cordova/ionic plugins will be installed 

├── resources // icon and splash screen 

├── scss // scss code, which will output to www/css/

 |── www // application - JS code and libs, CSS, images, etc. 

      |---------css //customs styles 

      |---------img //app images 

      |---------js //angular app and custom JS 

      |---------lib //third party libraries 

      |---------index.html //app master page 

├── bower.json // bower dependencies 

├── config.xml // cordova configuration 

├── gulpfile.js // gulp tasks 

├── ionic.project // ionic configuration 

├── package.json // node dependencies

The structure is shared by Chris Nwamba at https://scotch.io/tutorials/create-your-first-mobile-app-with-angularjs-and-ionic

Following are current potential templates that you can use:

• tabs : a simple 3 tab layout
• sidemenu: a layout with a swipable menu on the side
• blank: a bare starter with a single page
• super: starter project with over 14 ready to use page designs
• tutorial: a guided starter project

Once it is completed, you will get to see the following message appear:

  ionic serve                                                              
                                                                           
Run on a device or simulator:                                              
  ionic run ios[android,browser]                                           
                                                                           
Share your app with testers, and test on device easily with the Ionic View companion app:                                                             
  http://view.ionic.io                                                     

Yeah... now you test your apps. Just run ionic serve to view on your browser. It will pop-up your browser and automatically navigate to http://localhost:8100 ... else, you can open your browser and go to the address.

If you want to view in mobile, you may use mobile emulator or deploy on your mobile. Before that, do install mobile platform package first. To do that, run the following command:

                                                                       

ionic platform add ios  // to add ios platform into the package      
                                                                     
ionic platform add android //to add android platform into the package  

                                                                       

Finally, you are ready to run (on emulator or actual device).

                                                                           

ionic run android --prod --release //to run on emulator as production mode 

                                                                           

ionic build android --prod --release //to build as package for installation

                                                                           

For ios, it will require more steps and you can follow it https://ionicframework.com/docs/v2/intro/deploying/.

Lets dance... :)

Directory Listener (java code) - finally on github

Hi guys.. it has been a while since I last wrote anything here.

Just wanna share with you my latest contribution to community. I've uploaded a simple directory listener code written in java. What it does?
1. Listen to any directory pass as parameter
2. Basically alert you through message prompt on any activity done.

It can be further extended for any process you wish.

Feel free to use the code. It can be downloaded at
https://github.com/masteramuk/Java-Directory-Watcher

Adios..
