Try it like below:

    start-job -filepath myscript.ps1 -arg (,$myarr)

The `-ArgumentList` takes in a list/array of arguments. So when you give `-arg $myarr`, it is as though you are passing the elements of the array as the arguments. So you have to force PowerShell to treat it as a single argument which is an array.

I understand that css rules can target elements specified by attribute values, e.g.:

    input[type=&quot;text&quot;] {}

Can I make a rule that targets elements which *omit* a certain attribute?  For example, can I target &lt;a&gt; elements that lack an href or &lt;input&gt; elements that don&#39;t specify a type?

Is there a CSS selector for elements lacking an attribute?

For some reason, it looks like I cannot pass array of strings as parameter to scriptblock. What am I doing here wrong?

My script which is called from another script:

    param(
        [parameter(Mandatory=$true)]
        [string[]]$myarr
    )

    foreach ($elem in $myarr){
        $elem
    }

I call it from another script as

     $myarr = @(&quot;111&quot;, &quot;222&quot;)
     start-job -filepath myscript.ps1 -arg $myarr

I got only the first item in the array - &quot;111&quot;.

Assume you have a basic `Employee` class as such:
    
    class Employee
    {
       public string Name;
       public int Years;
       public string Department;
    }


Then (in a seperate class) I have the following code fragments (I think i understand all but the last):


I believe that the following code fragment works because the array initiliser creates an array of Employee objects which are the same type as the workforce variable being assigned to.

    Employee[] workforceOne = new Employee[] {
       new Employee() { Name = &quot;David&quot;, Years = 0, Department = &quot;software&quot; },
       new Employee() { Name = &quot;Dexter&quot;, Years = 3, Department = &quot;software&quot; },
       new Employee() { Name = &quot;Paul&quot;, Years = 4, Department = &quot;software&quot; } };


I then have the following code fragment.  I believe this works because the array of `Employee` objects implicity is an implementation of the Array() class which implements `IEnumerable`.  Therefore, I believe this is why the array can be assigned to IEnumerable?

    IEnumerable workforceTwo = new Employee[] {
       new Employee() { Name = &quot;David&quot;, Years = 0, Department = &quot;software&quot; },
       new Employee() { Name = &quot;Dexter&quot;, Years = 3, Department = &quot;software&quot; },
       new Employee() { Name = &quot;Paul&quot;, Years = 4, Department = &quot;software&quot; } };


Then I have this code fragment:

    IEnumerable&lt;Employee&gt; workforceThree = new Employee[] {
       new Employee() { Name = &quot;David&quot;, Years = 0, Department = &quot;software&quot; },
       new Employee() { Name = &quot;Dexter&quot;, Years = 3, Department = &quot;software&quot; },
       new Employee() { Name = &quot;Paul&quot;, Years = 4, Department = &quot;software&quot; } };

**I am not sure why this code fragment works?**  `IEnumerable&lt;Employee&gt;` inherits from `IEnumerable` (and overrides (or overloads?) the `GetEnumerator()` method) but shouldn&#39;t i therefore need a cast for the above to work as such:

    //The cast does work but is not required
    IEnumerable&lt;Employee&gt; workforceFour = (IEnumerable&lt;Employee&gt;)new Employee[] {
       new Employee() { Name = &quot;David&quot;, Years = 0, Department = &quot;software&quot; },
       new Employee() { Name = &quot;Dexter&quot;, Years = 3, Department = &quot;software&quot; },
       new Employee() { Name = &quot;Paul&quot;, Years = 4, Department = &quot;software&quot; } };

It seems that the array is being implicitly down cast from a type of `IEnumerable` to `IEnumerable&lt;Employee&gt;` but I always thought when you needed to convert a type to something more specific you needed an explicit cast.


Maybe i&#39;m missing something simple in my understanding here but can someone please help me with my understanding around this.

Thank you.

Casting array to IEnumerable&lt;T&gt;

For example, I have:

    var Data = [
      { id_list: 1, name: &#39;Nick&#39;, token: &#39;312312&#39; },
      { id_list: 2, name: &#39;John&#39;, token: &#39;123123&#39; },
    ]

Then, I want to **sort/reverse** this object by `name`, for example. And then I want to get something like this:

    var Data = [
      { id_list: 2, name: &#39;John&#39;, token: &#39;123123&#39; },
      { id_list: 1, name: &#39;Nick&#39;, token: &#39;312312&#39; },
    ]

And now I want to know the index of the object with property `name=&#39;John&#39;` to get the value of the property token.

How do I solve the problem?

I would like to know how to check if an array is empty or null in jQuery. I tried `array.length === 0` but it didn&#39;t work. It did not throw any error either.

This is the code:

	

    var album_text = new Array();
    
    $(&quot;input[name=&#39;album_text[]&#39;]&quot;).each(function(){
      if( $(this).val() &amp;&amp;  $(this).val() != &#39;&#39;) {
        album_text.push($(this).val());
      }
    });
    if (album_text.length === 0) {
      $(&#39;#error_message&#39;).html(&quot;Error&quot;);
    }
    
    else {
      // send data
    }

I&#39;m trying to turn a list of 2d numpy arrays into a 2d numpy array.  For example, 

    dat_list = []
    for i in range(10):
        dat_list.append(np.zeros([5, 10]))

What I would like to get out of this list is an array that is (50, 10).  However, when I try the following, I get a (10,5,10) array.

    output = np.array(dat_list)

Thoughts?

I want to pass value to `remoteCommand` from javascript. If this is possible, how can I do that and how can I receive them in the backing bean?



Pass parameter to p:remoteCommand from JavaScript

To date I use the [following][1] implementation of the builder pattern (as opposed to the implementation described [here][2]):

    public class Widget {
        public static class Builder {
            public Builder(String name, double price) { ... }
            public Widget build() { ... }
            public Builder manufacturer(String value) { ... }
            public Builder serialNumber(String value) { ... }
            public Builder model(String value) { ... }
        }

        private Widget(Builder builder) { ... }
    }

This works well for most situations I&#39;ve encountered where I need to build up a complex object with a variety of required/mandatory and optional parameters. However, I&#39;ve been struggling lately to understand how the pattern is of any benefit when all your parameters are mandatory (or at least the vast majority are).

One means of getting around this has been to logically group the parameters being passed in to their own classes to reduce the number of parameters being passed to the builder constructor. 

For example, instead of:

    Widget example = new Widget.Builder(req1, req2, req3,req4,req5,req6,req7,req8)
                               .addOptional(opt9)
                               .build();

becomes grouped as follows:

    Object1 group1 = new Object1(req1, req2, req3, req4);
    Object2 group2 = new Object2(req5, req6);
    
    Widget example2 = new Widget.Builder(group1, group2, req7, req8)
                                .addOptional(opt9)
                                .build();

While having separate objects simplifies things quite a bit, it also makes things a little difficult to follow if one is not familiar with the code. One thing I considered was moving all parameters into their own `addParam(param)` methods and then performing validation on required parameters in the `build()` method.

What is best practice and is there perhaps a better approach to this that I haven&#39;t considered?

I have a somewhat detailed query in a script that uses `?` placeholders.  I wanted to test this same query directly from the psql command line (outside the script).  I want to avoid going in and replacing all the `?` with actual values, instead I&#39;d like to pass the arguments after the query.

Example:

    SELECT  * 
    FROM    foobar
    WHERE   foo = ?
       AND  bar = ?
        OR  baz = ?  ;

Looking for something like:

    %&gt; {select * from foobar where foo=? and bar=? or baz=? , &#39;foo&#39;,&#39;bar&#39;,&#39;baz&#39; };

PostgreSQL: How to pass parameters from command line?

Is this link valid?

    &lt;a href=&quot;?lang=en&quot;&gt;eng&lt;/a&gt;

I know the browsers treat it as expected and I know the [empty link would be ok][1] too - but is it ok to specify just the parameters?

I am curious because question mark (&quot;?&quot;) is only a convention by most HTTP servers (AFAIK), though I admit it is a prevailing one.

So, to recap:

 1. will all browsers interpret this correctly?

 2. is this in RFC?

 3. can I expect some trouble using this?

Apparently, we can pass complex class instances to functions, but why can&#39;t we pass arrays to functions?

Is there a way to match any class argument of the below sample routine?

    class A {
         public B method(Class&lt;? extends A&gt; a) {}
    }

How can I **always** return a `new B()` regardless of which class is passed into `method`? The following attempt only works for the specific case where `A` is matched. 


    A a = new A();
    B b = new B();
    when(a.method(eq(A.class))).thenReturn(b);

    # List of values that I want to pass into foo.
    values = [1,2,3]
    
    # I want to do something like this, and get the result &quot;1, 2, 3&quot;:
    foo( values.howDoYouExpandMe() )

&lt;!-- language-all: lang-cpp --&gt;

I&#39;m new to move semantics in C++11 and I don&#39;t know very well how to handle `unique_ptr` parameters in constructors or functions. Consider this class referencing itself:

    #include &lt;memory&gt;

    class Base
    {
      public:
    
        typedef unique_ptr&lt;Base&gt; UPtr;
    
        Base(){}
        Base(Base::UPtr n):next(std::move(n)){}
    
        virtual ~Base(){}
    
        void setNext(Base::UPtr n)
        {
          next = std::move(n);
        }
    
      protected :
    
        Base::UPtr next;
    
    };

Is this how I should write functions taking `unique_ptr` arguments?

And do I need to use `std::move` in the calling code?

    Base::UPtr b1;
    Base::UPtr b2(new Base());
    
    b1-&gt;setNext(b2); //should I write b1-&gt;setNext(std::move(b2)); instead?
