It means that AreSame() checks that they are the exact same object - if reference indicate the same object in memory. 

AreEqual() checks that objects has equal type and value. Equal objects can exist in two different places in memory.

`Assert.AreEqual(a, b)` is the same as `Assert.IsTrue(Object.Equals(a, b))`

`Assert.AreSame(a, b)` is the same as `Assert.IsTrue(Object.ReferenceEquals(a, b))`

(the only reason I knew is I just figured it out myself a few hours ago today because I needed to do a `Assert.IsTrue(Object.ReferenceEquals(a,b))` and thought *&quot;I wonder if there is a better way to do this&quot;)*

I&#39;m trying to get the most popular hackathons which requires ordering by the respective hackathon&#39;s `partipants-&gt;count()`. Sorry if that&#39;s a little difficult to understand.

I have a database with the following format:

    hackathons
        id
        name
        ...

    hackathon_user
        hackathon_id
        user_id

    users
        id
        name

The `Hackathon` model is:

    class Hackathon extends \Eloquent {
	    protected $fillable = [&#39;name&#39;, &#39;begins&#39;, &#39;ends&#39;, &#39;description&#39;];

	    protected $table = &#39;hackathons&#39;;

	    public function owner()
	    {
		    return $this-&gt;belongsToMany(&#39;User&#39;, &#39;hackathon_owner&#39;);
	    }

	    public function participants()
	    {
		    return $this-&gt;belongsToMany(&#39;User&#39;);
	    }

	    public function type()
	    {
		    return $this-&gt;belongsToMany(&#39;Type&#39;);
	    }
    }

And `HackathonParticipant` is defined as:

    class HackathonParticipant extends \Eloquent {
	
	    protected $fillable = [&#39;hackathon_id&#39;, &#39;user_id&#39;];

	    protected $table = &#39;hackathon_user&#39;;

	    public function user()
	    {
		    return $this-&gt;belongsTo(&#39;User&#39;, &#39;user_id&#39;);
	    }

	    public function hackathon()
	    {
		    return $this-&gt;belongsTo(&#39;Hackathon&#39;, &#39;hackathon_id&#39;);
	    }
    }

I&#39;ve tried `Hackathon::orderBy(HackathonParticipant::find($this-&gt;id)-&gt;count(), &#39;DESC&#39;)-&gt;take(5)-&gt;get());` but I feel like I made a big mistake (possibly the $this-&gt;id), because it doesn&#39;t work at all.

How would I go about trying to get the most popular hackathons which is based on the highest number of related hackathonParticipants?

I hit this TypeError exception recently, which I found very difficult to debug. I eventually reduced it to this small test case:

    &gt;&gt;&gt; &quot;{:20}&quot;.format(b&quot;hi&quot;)
    Traceback (most recent call last):
      File &quot;&lt;stdin&gt;&quot;, line 1, in &lt;module&gt;
    TypeError: non-empty format string passed to object.__format__

This is very non-obvious, to me anyway. The workaround for my code was to decode the byte string into unicode:

     &gt;&gt;&gt; &quot;{:20}&quot;.format(b&quot;hi&quot;.decode(&quot;ascii&quot;))
     &#39;hi                  &#39;

What is the meaning of this exception? Is there a way it can be made more clear?

I would like to add Authorization to a controller, for multiple Roles at once.

Normally that would look like this:

    [Authorize(Roles = &quot;RoleA,RoleB,RoleC&quot;)]
    public async Task&lt;ActionResult&gt; Index()
    {
    }

But I have stored my Roles in consts, since they might change or be extended at some point.

    public const RoleA = &quot;RoleA&quot;;
    public const RoleB = &quot;RoleB&quot;;
    public const RoleC = &quot;RoleC&quot;;

I cannot do this, since the string must be known at compile time:

    [Authorize(Roles = string.join(&quot;,&quot;,RoleA,RoleB,RoleC)]
    public async Task&lt;ActionResult&gt; Index()
    {
    }

Is there a way to circumvent the problem?

I COULD write a const which simply contains &quot;RoleA,RoleB,RoleC&quot; - but I dislike magic strings and this is a magic string. Changing the name of a Role and forgetting to change the combined string would be a disaster.

I am using MVC5. ASP.NET Identity and the Role are known at compile time.

I&#39;m currently working on a very performance critical program and one path I decided to explore that may help reduce resource consumption was increasing my worker threads&#39; stack size so I can move most of the data (`float[]`s)  that I&#39;ll be accesing onto the stack (using [`stackalloc`](http://msdn.microsoft.com/en-us/library/cx9s2sy4(v=vs.80).aspx)).

I&#39;ve [read](https://stackoverflow.com/a/823729/2246344) that the default stack size for a thread is 1 MB, so in order to move all my `float[]`s I would have to expand the stack by approximately 50 times (to 50 MB~).

I understand this is generally considered &quot;unsafe&quot; and isn&#39;t recommended, but after benchmarking my current code against this method, I&#39;ve discovered a *530%* increase in processing speed! So I can not simply pass by this option without further investigation, which leads me to my question; what are the dangers associated with increasing the stack to such a large size (what could go wrong), and what precautions should I take to minimise such dangers?

My test code,

    public static unsafe void TestMethod1()
    {
        float* samples = stackalloc float[12500000];

        for (var ii = 0; ii &lt; 12500000; ii++)
        {
            samples[ii] = 32768;
        }
    }

    public static void TestMethod2()
    {
        var samples = new float[12500000];

        for (var i = 0; i &lt; 12500000; i++)
        {
            samples[i] = 32768;
        }
    }

What are the dangers when creating a thread with a stack size of 50x the default?

I have created and installed a service a couple of times. Initially it was working fine, but after some changes in the service Code it start giving the error when I restart the service in Services.msc :

&gt;Error 1053: the service did not respond to the start or control request in a    timely fashion

Code:

    public partial class AutoSMS : ServiceBase
    {
        public AutoSMS()
        {
            InitializeComponent();
            eventLog1.Clear();
    
            if (!System.Diagnostics.EventLog.SourceExists(&quot;MySource&quot;))
            {
                System.Diagnostics.EventLog.CreateEventSource(
                    &quot;MySource&quot;, &quot;MyNewLog&quot;);
            }
            eventLog1.Source = &quot;MySource&quot;;
            eventLog1.Log = &quot;MyNewLog&quot;;
    
            Timer checkForTime = new Timer(5000);
            checkForTime.Elapsed += new ElapsedEventHandler(checkForTime_Elapsed);
            checkForTime.Enabled = true;
    
        }
    
        protected override void OnStart(string[] args)
        {
            eventLog1.WriteEntry(&quot;In OnStart&quot;);
        }
    
        protected override void OnStop()
        {
            eventLog1.WriteEntry(&quot;In onStop.&quot;);
        }
    
    
        void checkForTime_Elapsed(object sender, ElapsedEventArgs e)
        {
            string Time = &quot;15:05:00&quot;;
            DateTime dateTime = DateTime.ParseExact(Time, &quot;HH:mm:ss&quot;,
                                            CultureInfo.InvariantCulture);
    
            if (DateTime.Now == dateTime) ;
                eventLog1.WriteEntry(Time);
        }
    }

Here is my main method code

    static void Main()
    {
        ServiceBase[] ServicesToRun;
        ServicesToRun = new ServiceBase[] 
        { 
            new AutoSMS() 
        };
        ServiceBase.Run(ServicesToRun);
    }

I also tried the following steps :

- Go to Start &gt; Run &gt; and type regedit
- Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
- With the control folder selected, right click in the pane on the right and - select new DWORD Value
- Name the new DWORD: ServicesPipeTimeout 
- Right-click ServicesPipeTimeout, and then click Modify
- Click Decimal, type &#39;180000&#39;, and then click OK
- Restart the computer


I used to install and uninstall it with following command :

    installutil AutoSMS.exe

    installutil /u AutoSMS.exe

I want to get the first day and last day of the month where a given date lies in. The date comes from a value in a UI field.

If I&#39;m using a time picker I could say

    var maxDay = dtpAttendance.MaxDate.Day;


But I&#39;m trying to get it from a DateTime object. So if I have this...

    DateTime dt = DateTime.today;

My lecturer has asked me that in class, and I was wondering why is it a macro instead of a function? 

Why is assert a macro and not a function?

Code:-

    try {
        Assert.assertEquals(&quot;1&quot;, &quot;2&quot;);
    } catch (Exception e) {
        System.out.println(&quot;I am in error block&quot;);
    }

If the assert statements fails, I would like to capture the error in the catch block. I am trying with the above code and its not happening.

Will the assertion error be caught by in a catch block for java exception?

I want to use assert between 2 two decimal, I use this:

    BigDecimal bd1 = new BigDecimal (1000);
    BigDecimal bd2 = new BigDecimal (1000);
    org.junit.Assert.assertSame (bd1,bd2);

but the JUnit log shows:

    expected &lt;1000&gt; was not: &lt;1000&gt;

I have been learning Python for a while and the `raise` function and `assert` are (what I realised is that both of them crash the app, unlike try - except) really similar and I can&#39;t see a situation where you would use `raise` or `assert` over `try`. 

So, what is the difference between `raise`, `try`, and `assert`?


What&#39;s the difference between raise, try, and assert?

I am getting the following error:

    Both assertEquals(Object, Object) in Assert and assertEquals(double, double) in Assert match

For this line of code in my `Junit` tests, note that `getScore`() returns a `double`: 

    assertEquals(2.5, person.getScore());

This is my assert import:

    import static org.junit.Assert.*;

What is causing this and how can I fix this?
