    (click)=&quot;idx &gt; 0 &amp;&amp; removeSelected(item.spId)&quot;

Simply use a ternary:

    &lt;div class=&quot;trashIconDiv&quot; (click)=&quot;idx &gt; 0 ? removeSelected(item.spId) : false&quot;&gt;

This will only call `removeSelected` function when the condition is true, if it&#39;s false then it won&#39;t do anything.

I have windows 10 and I want to execute the sh command in the Jenkinsfile from Jenkins pipeline using bash for Ubuntu for windows, but it doesn&#39;t work

I have the following stage in my Jenkins pipeline :

    stage(&#39;sh how to&#39;) {
            steps {
                sh &#39;ls -l&#39;
            }
        }

The error message is :

&gt; [C:\Program Files (x86)\Jenkins\workspace\pipelineascode] Running shell script
Cannot run program &quot;nohup&quot; (in directory &quot;C:\Program Files (x86)\Jenkins\workspace\pipelineascode&quot;): CreateProcess error=2, Le fichier sp&#233;cifi&#233; est introuvable

I tried changing Jenkins parameter-&gt;shell executable with 
&gt; C:\Windows\System32\bash.exe

but same error...

how to run sh script using windows 10&#39;s bash?

I looking for ways to read data from multiple partitioned directories from s3 using python.

data_folder/serial_number=1/cur_date=20-12-2012/abcdsd0324324.snappy.parquet
data_folder/serial_number=2/cur_date=27-12-2012/asdsdfsd0324324.snappy.parquet

pyarrow&#39;s ParquetDataset module has the capabilty to read from partitions. So I have tried the following  code : 

    &gt;&gt;&gt; import pandas as pd
    &gt;&gt;&gt; import pyarrow.parquet as pq
    &gt;&gt;&gt; import s3fs
    &gt;&gt;&gt; a = &quot;s3://my_bucker/path/to/data_folder/&quot;
    &gt;&gt;&gt; dataset = pq.ParquetDataset(a)

It threw the following error :

    Traceback (most recent call last):
      File &quot;&lt;stdin&gt;&quot;, line 1, in &lt;module&gt;
      File &quot;/home/my_username/anaconda3/lib/python3.6/site-packages/pyarrow/parquet.py&quot;, line 502, in __init__
        self.metadata_path) = _make_manifest(path_or_paths, self.fs)
      File &quot;/home/my_username/anaconda3/lib/python3.6/site-packages/pyarrow/parquet.py&quot;, line 601, in _make_manifest
        .format(path))
    OSError: Passed non-file path: s3://my_bucker/path/to/data_folder/

Based on documentation of pyarrow I tried using s3fs as the file system, ie :

    &gt;&gt;&gt; dataset = pq.ParquetDataset(a,filesystem=s3fs)

Which throws the following error : 

    Traceback (most recent call last):
      File &quot;&lt;stdin&gt;&quot;, line 1, in &lt;module&gt;
      File &quot;/home/my_username/anaconda3/lib/python3.6/site-packages/pyarrow/parquet.py&quot;, line 502, in __init__
        self.metadata_path) = _make_manifest(path_or_paths, self.fs)
      File &quot;/home/my_username/anaconda3/lib/python3.6/site-packages/pyarrow/parquet.py&quot;, line 583, in _make_manifest
        if is_string(path_or_paths) and fs.isdir(path_or_paths):
    AttributeError: module &#39;s3fs&#39; has no attribute &#39;isdir&#39;

I am limited to use a ECS cluster, hence **spark/pyspark is not an option**.

Is there a way we can easily read  the parquet files easily, in python from such partitioned directories in s3 ? I feel that listing the all the directories and then reading the is not a good practise as suggested in this [link](https://stackoverflow.com/questions/45043554/how-to-read-a-list-of-parquet-files-from-s3-as-a-pandas-dataframe-using-pyarrow). I would need to convert the read data to a pandas dataframe for further processing &amp; hence prefer options related to fastparquet or pyarrow. I am open to other options in python as well.

In my application I would like to have conditional based click event , 

    &lt;div class=&quot;trashIconDiv&quot; (click)=&quot;if(idx &gt; 0) {removeSelected(item.spId)}&quot;&gt;

In the above code removeSelected function should be executed only when idx &gt;0 , any idea how to implement

I have a date value in each of my objects that I can Print like this:

    &lt;td&gt; {{competition.compStart }}&lt;/td&gt;

And here is how it looks: 

    1931-05-31T00:00:00.000+0000

In order to change the format to make it more readable I&#39;m using the Angular date pipe: 

    &lt;td&gt; {{competition.compStart | date : &quot;dd/MM/yyyy&quot;}}&lt;/td&gt;

With this result: 

    30/05/1931

As you can see, It is displaying the previous day (May 30 instead of May 31).

As far as I understand, the problem is related to the timezone, since I&#39;m in Argentina and we have GMT-3 then 00:00 of the 31st minus 3 hours would be May 30 at 9 PM.

So how can I make it take the time literally and not process it based on the timezone, but still apply the format in the pipe?

In Angular 4, I&#39;m trying to subscribe to the valueChanges of a FormControl. Neither of the versions below is working. I&#39;m not seeing any errors. The form.value JSON is updating as I type, but the subscription isn&#39;t working. 
  

    myForm: FormGroup;
    public firstName = new FormControl();
    public lastName = new FormControl();
    
    this.myForm = this.formBuilder.group({ 
          firstName: &#39;&#39;,
          lastName: &#39;&#39;,
    });
    
    this.myForm.controls.firstName.valueChanges.subscribe(value =&gt; {
          console.log(value);
    });
    
        
    this.myForm.get(&#39;firstName&#39;).valueChanges.subscribe(value =&gt; {
          console.log(&#39;name has changed:&#39;, value)
    });


Here&#39;s a template snippet.

    &lt;form #myForm=&quot;ngForm&quot;&gt;
    
    &lt;md-input-container&gt;
        &lt;input mdInput name=&quot;firstName&quot; [(ngModel)]=&quot;firstName&quot; placeholder=&quot;enter name&quot;/&gt;
    &lt;/md-input-container&gt;
                   
    
&lt;pre&gt;{{ myForm.value | json }}&lt;/pre&gt;
