Recall that [**propagation delay**][1] d/s is the time to transmit one bit over a link

And [**transmission delay**][2] is the time to transmit a whole packet over a link


  [1]: http://en.wikipedia.org/wiki/Propagation_delay
  [2]: http://en.wikipedia.org/wiki/Transmission_delay

Then, why isn&#39;t **packet length * propagation delay = transmission delay**?


Propagation Delay vs Transmission delay

Suppose I have the following entities (classes)

    public class Target
    {
        public string Value;
    }


    public class Source
    {
        public string Value1;
        public string Value2;
    }


Now I want to configure Auto Map, to Map Value1 to Value if Value1 starts with &quot;A&quot;, but otherwise I want to map Value2 to Value.

This is what I have so far:

    Mapper
        .CreateMap&lt;Source,Target&gt;()
        .ForMember(t =&gt; t.Value, 
            o =&gt; 
                {
                    o.Condition(s =&gt; 
                        s.Value1.StartsWith(&quot;A&quot;));
                    o.MapFrom(s =&gt; s.Value1);
                      &lt;&lt;***But then how do I supply the negative clause!?***&gt;&gt;
                })


However the part the still eludes me is how to tell AutoMapper to *go take `s.Value2`* should the earlier condition fails. 

It just seems to me the API was not designed as well as it could be... but may be it&#39;s my lack of knowledge getting in the way.

I have a bunch of labels in a text file (e.g. MY LABEL:) that I need to make title case.

I already know how I would make them all lower or upper case.

For example:

`^([A-Z &amp;#]+:)` to `\L$1`

However, is there a simple switch-based way to get title case?

Sublime Text: Regex to convert Uppercase to Title Case?

I have a bunch of labels in a text file (e.g. MY LABEL:) that I need to make title case.
I already know how I would make them all lower or upper case.
For example:
<code>^([A-Z &#x26;#]+:)</code> to <code>\L$1</code>
However, is there a simple switch-based way to get title case?

In the regex below, `\s` denotes a space character.  I imagine the regex parser, is going through the string and sees `\` and knows that the next character is special.

But this is not the case as double escapes are required.

Why is this?

    var res = new RegExp(&#39;(\\s|^)&#39; + foo).test(moo);

Is there a concrete example of how a single escape could be mis-interpreted as something else?

Why do regex constructors need to be double escaped?

I want to **add a (variable) tag** to values with regex, the pattern works fine with PHP but I have troubles implementing it into JavaScript.

The pattern is (`value` is the variable):

    /(?!(?:[^&lt;]+&gt;|[^&gt;]+&lt;\/a&gt;))\b(value)\b/is

I escaped the backslashes:

    var str = $(&quot;#div&quot;).html();
    var regex = &quot;/(?!(?:[^&lt;]+&gt;|[^&gt;]+&lt;\\/a&gt;))\\b(&quot; + value + &quot;)\\b/is&quot;;
    $(&quot;#div&quot;).html(str.replace(regex, &quot;&lt;a href=&#39;#&quot; + value +&quot;&gt;&quot; + value + &quot;&lt;/a&gt;&quot;));

But this seem not to be right, I logged the pattern and its exactly what it should be.
Any ideas?

I&#39;m trying to match some lines against regex that contains digits.

Bash version 3.2.25:

    #!/bin/bash
    
    s=&quot;AAA (bbb 123) CCC&quot;
    regex=&quot;AAA $bbb \d+$ CCC&quot;
    if [[ $s =~ $regex ]]; then
      echo $s matches $regex
    else
      echo $s doesnt match $regex
    fi

Result:

    AAA (bbb 123) CCC doesnt match AAA $bbb \d+$ CCC


If I put `regex=&quot;AAA $bbb .+$ CCC&quot;` it works but it doesn&#39;t meet my requirement to match digits only.

Why doesn&#39;t `\d+` match `123`?

I am trying to understand this code block. In the first one, what is it we are looking for in the expression?

My understanding is that it is any character (0 or more times *) followed by any number between 0 and 9 (one or more times +) followed by any character (0 or more times *).

When this is executed the result is:

&lt;!-- language: lang-none --&gt;

    Found value: This order was placed for QT3000! OK?
    Found value: This order was placed for QT300
    Found value: 0

Could someone please go through this with me?

What is the advantage of using Capturing groups?

		    String line = &quot;This order was placed for QT3000! OK?&quot;; 
		    String pattern = &quot;(.*)(\\d+)(.*)&quot;;

		    // Create a Pattern object
		    Pattern r = Pattern.compile(pattern);

		    // Now create matcher object.
		    Matcher m = r.matcher(line);

		    if (m.find()) {
			    System.out.println(&quot;Found value: &quot; + m.group(0));
			    System.out.println(&quot;Found value: &quot; + m.group(1));
			    System.out.println(&quot;Found value: &quot; + m.group(2));
		    } else {
			    System.out.println(&quot;NO MATCH&quot;);
		    }
	    }

    }

I have the following test file

    AAA
    BBB
    CCC

Using the following sed I can comment out the _BBB_ line.

    # sed -e &#39;/BBB/s/^/#/g&#39; -i file

I&#39;d like to only comment out the line if it does not already has a # at the begining.

    # sed -e &#39;/^#/! /BBB/s/^/#/g&#39; file

    sed: -e expression #1, char 7: unknown command: `/&#39;

Any ideas how I can achieve this?

**Case 1:**

    &quot;{arg1} {arg2}&quot;.format(10, 20)
It will give `KeyError: &#39;arg1&#39;` because I didn&#39;t pass the named arguments.

**Case 2:**

    &quot;{arg1} {arg2}&quot;.format(arg1=10, arg2=20)
Now it will work properly because I passed the named arguments.
And it prints `&#39;10 20&#39;`

**Case 3:**

And, If I pass wrong name it will show `KeyError: &#39;arg1&#39;`

    &quot;{arg1} {arg2}&quot;.format(wrong=10, arg2=20)
But,

**Case 4:**

If I pass the named arguments in **wrong order**

    &quot;{arg1} {arg2}&quot;.format(arg2=10, arg1=20)
*It works...*

and it prints `&#39;20 10&#39;`

My question is why does it work and what&#39;s the use of **named arguments** in this case.

I&#39;d like to store a lot of words in a list. Many of these words are very similar. For example I have word `afrykanerskojęzyczny` and many of words like `afrykanerskojęzycznym`, `afrykanerskojęzyczni`, `nieafrykanerskojęzyczni`. What is the effective (fast and giving small diff size) solution to find difference between two strings and restore second string from the first one and diff?

I have a dataframe in pandas with mixed int and str data columns. I want to concatenate first the columns within the dataframe. To do that I have to convert an `int` column to `str`. 
I&#39;ve tried to do as follows:

    mtrx[&#39;X.3&#39;] = mtrx.to_string(columns = [&#39;X.3&#39;])

or 

    mtrx[&#39;X.3&#39;] = mtrx[&#39;X.3&#39;].astype(str)

but in both cases it&#39;s not working and I&#39;m getting an error saying &quot;cannot concatenate &#39;str&#39; and &#39;int&#39; objects&quot;. Concatenating two `str` columns is working perfectly fine.

Though I have tried to modify &quot;font.size&quot; in classes like &quot;Label_control&quot; and &quot;sidebar_control&quot; in the Package &quot;Theme-Default&quot;, the font size of the editor does not change at all. Is there anything different in sublime text3？
