Big Business Goals? Which KPIs Will Help You
Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

visio 2013 standard does not show the "UML Sequence" template as shown below
https://www.youtube.com/watch?v=_xtZIDI8Ajg
only professional viso 2013 shows it?
are there existing sample diagrams which i can use as sample and modify on top of them easily?
any alternate tool to draw these type of diagrams easily apart from visio like free open source tools?
Please advise

Controllable Knight Rider LED project

I have a WS2812B-5M light strip and a SP105E Magic Controller.  Unfortunately, the SP105E does not have the mode I would like.

Specifically, i'd like to cut off about 30" of LED strip and make a controllable Knight Rider type light strip.  

What I mean about Knight Rider is that one LED will fade in then one LED will be bright and then the trailing LED fade out while moving from one end of the strip to the other and back again.  The SP105E does not have a preset program that does this.

I would also like to control:
     1.  the color of the LED
     2.  the speed of the LED (how fast the LED moves from one end and back)

The control can happen with a USB connection to my laptop although a Bluetooth iPhone connection like the SP105E would be preferred.

Can someone suggest
     1.  where I can get this code for a Knight Rider effect (or where I can have it coded for it to be fully controllable)
     2.  what controller, or hardware (Bluetooth would be so cool), I would need to download the code into and then connect to the light strip
     3.  and what I would need on my computer to download from my computer to the controller or
     4.  what software on my computer to have the light strip connected to my computer via usb to control the LED strip

thanks for your help!

Scenario:
A particular business card design can only accommodate up to three phone numbers.

Assume the phone numbers are always formatted as 10 digits with dashes. For example:
   Mobile: 456-789-1234
   Office: 987-654-3210
   Fax: 345-678-9012

There are only 2 lines to accommodate 3 phone numbers.

If (and only if) all 3 phone numbers contain a value, then the mobile and office numbers must appear on the first line, and the fax must appear on the second line, like this:
Mobile: 456-789-1234    Office: 987-654-3210
Fax: 345-678-9012

If (and only if) one of the 3 phone numbers does not contain a value, then the remaining 2 numbers must appear on their own line, like this:
Mobile: 456-789-1234
Fax: 345-678-9012

The example above assumes the Office number is the empty field. But if the Mobile number was the empty field then it would look like this:
Office: 987-654-3210
Fax: 345-678-9012

And if the Fax number was the empty field, then it would look like this:
Mobile: 456-789-1234
Office: 987-654-3210

If 2 of the 3 numbers are empty, then return just the one remaining number.

So given all of the possible phone number combinations, we have:
M   O   F
M   O
M       F
M
    O   F
    O
        F

I have a multi-dimensional array that i want to loop through and find any key/value duplicates. If there is a duplicate i want to add the quantities together and then remove one of them from my array (array_filter).

For example, this is my Array of Arrays. If there is a duplicate sku => i want to add their quantities together and then remove one from the array based on the ID (it will always be unique).

DEP1030BLKCO - this sku is duplicated twice. So i would like to add their quantities together (8+8) and remove one of their keys so its a single DEP1030BLKCO sku with quantity of 16.

I know that i can initialize an array variable $duplicates to store IDs of duplicates and then use an array filter function to filter out any IDs added to the array (essentially removing duplicates) but how can i find the duplicates? I saw array_unique but im unsure if that will help in this situation.

Is there a better approach than *this?

Array (   

  [DEP2000RODSIDL2] => Array
        (
            [product_id] => 167
            [sku] => DEP2000RODSIDL2
            [name] => Side Rod - Large
            [weight] => 1.00
            [quantity] => 32
            [product_options] => 
            [id] => DEPRODSIDL

In Component-Based Software Engineering (CBSE) we turn requirements into a domain model and use cases.
Then we turn use cases into interfaces.
And finally, we factor interfaces and turn them into components.

Question about openxml and column width.
I set the column width like the following

Columns columns = new Columns(
                        new Column // Pos No.
                    {
                            Min = 1,
                            Max = 1,
                            Width = 3.71,
                            CustomWidth = True
                        },

Open in new window

I check the XML (open up the .xmlx file in VS2017) and it displays the correct value

<x:cols>
    <x:col min="1" max="1" width="3.71" customWidth="1" />
    <x:col min="2" max="3" width="11.5" customWidth="1" />
    <x:col min="4" max="4" width="4.86" customWidth="1" />
    <x:col min="5" max="5" width="7.71" customWidth="1" />
    <x:col min="6" max="6" width="7.14" customWidth="1" />
    <x:col min="7" max="8" width="8.14" customWidth="1" />
    <x:col min="9" max="9" width="4.86" customWidth="1" />
    <x:col min="10" max="12" width="8.14" customWidth="1" />
    <x:col min="13" max="13" width="8.43" customWidth="1" />
    <x:col min="14" max="14" width="22" customWidth="1" />
    <x:col min="15" max="15" width="6.14" customWidth="1" />
    <x:col min="16" max="16" width="20" customWidth="1" />
  </x:cols>

but when I view the excel file, the column width is smaller than whats specified.
What am I overlooking?

Hi,
There is following code -
 
     
   public CompletionStage<Void> addEmail(Long userID, String email) {

      CompletableFuture<GetMappingResponsePayload> getMappingResponsePayloadCompletionStage =
              (CompletableFuture<GetMappingResponsePayload>) addressResolver.getEmailMapping(email);

    return addressResolver.addEmailMapping(email, userID)
        .thenCompose(__ -> emailsDao.upsertEmail(userID, email, true));

Open in new window

I want to fetch the object GetMappingResponsePayload from above.
The getEmailMapping function is a synchronous call so when the code gets executed the result will be there.
To give the context there is a Boolean attribute inside GetMappingResponsePayload and based on that
i want to return an exceptionallyCompletedFuture in case the value is false.
otherwise the next return statement is executed.
How do i achieve this neatly

Thanks

I am trying to learn how to use D3.js so that I can produce graphs for visualized data on my web page which is based on using Javascript.
But I am struggling trying to get an axis scale correctly rendered.
Below is the code where I draw the graph and "attempt" to put the X & Y scales on the axis.   However, if you look at the attach JPG file, the X axis is being drawn at the TOP of the graph, not the bottom where it was supposed to be.   I was calling the d3.axisBottom() as you can seen from the code.  Also, the Y axis is being placed about 10 pixels inside the left side of the graph, again even though I am using the d3.axisLeft() class.  Again you can see this in the attached file screen shot.

From the code below, does anyone have any idea what I am doing wrong?

Thank you,



var dataset = [77,361,7,9,0,0,0,0,0,266,228,454];

var svgWidth = 500;
var svgHeight = 500;
var barPadding = 5;
var barWidth = (svgWidth / dataset.length);

var svg = d3.select('svg')
	.attr("width", svgWidth)
	.attr("height", svgHeight);


var xScale = d3.scaleLinear()
        .domain([0,svgWidth + 150])
        .range([0,svgWidth + 150]);

var x_axis = d3.axisBottom()
        .scale(xScale)
        .ticks(10);

svg.append("g")
        .call(x_axis);

var yScale = d3.scaleLinear()
        .domain([d3.min(dataset),(d3.max(dataset) + 200)])
        .range([svgHeight,0]);

var y_axis = d3.axisLeft()
        .scale(yScale);

svg.append("g")
        .attr("transform", "translate(50,10)")

Hi,

My requirement is to develop an application in power builder, which receives Scanned barcodes and decodes it

The application should also be able to reveal hidden ASCII codes in the scanned barcodes.
Like:-

ASCII Codes
TAB - 9
BS Backspace  - 8
EOT End of Transmission - 4
FF Form Feed - 12      
Etc.

When scanned codes arrives at datawindow, rich text input, single line edit  it comes as one character at a time
So my logic would be is to take that character before it is written in Datawindow or rich text input and  find its ascii value and if it is less the 32 (which means it is  a hidden character)
I can give brackets around it and show in display screen. so that hidden characters are not missed out.

Eg Scanned code abc<TAB>def<FF>gh

Decoded code will be abc[09]def[12]gh

So I tried with EditChanged, itemchanged , KeyDown events but I am unable to get the character before it is written in datawindow. Because once it is been written in datawindow hidden characters will be missed out.

Is there any event in powerbuilder will  give me the scannedcode after it has been scanned but before it has been written in data window or rich text control,
Something like PreviewTextInput Event, which will preview the  text before writing it into the data window.

Thanks and regards,

When using ExpandPath, I will occasionally get something unexpected. For instance, I'm trying to move a file from one directory to another.
<cffile action="MOVE" source="#ExpandPath('/tmp/bloop.jpg')#" destination="#ExpandPath('/final-images/bloop.jpg')#">

Open in new window


This is the error I'm receiving:
An exception occurred when performing a file operation moving a file to another filesystem on files /var/www/vhosts/[sitename].com/tmp/bloop.jpg and /opt/coldfusion10/cfusion/bin/redirect:/final-images/bloop.jpg.The cause of this exception was: java.io.FileNotFoundException: /opt/coldfusion10/cfusion/bin/redirect:/final-images/bloop.jpg (No such file or directory).

You'll notice that the expanded base of the source is /var/www/vhosts/[sitename].com (which is what you'd expect it to be) while that of the destination is /opt/coldfusion10/cfusion/bin/redirect:

What's going on here? This isn't the first time I've run across this issue, but I can't seem to Google anything up about it. We're running CF10 on a Linux server. Thanks!
