How do you save a single page or, individual pages from a PDF document?

A multi-page PDF document consists of a number of pages and sometimes you may need to save a single page or, a couple of individual pages often non-consecutive, from a PDF document.

How do you save a pages or pages from PDF document?

Here is one way you can do it (as I did) using Windows 10.

Just scroll to the page you want to save in your PDF reader program and when you are on the page click Print.

Choose Microsoft Print to PDF from the choice of Printers.

Click handle on Pages and pick 'Current Page'.

Click Print.

This opens 'Save Print Output As' dialogue. Provide a name for the file and save the page to your folder.

What is SPSS?

Data Science is trending. What with Machine Learning and Artificial Intelligence, learning to work with statistical analysis tools will take you far.

Here is an IBM one liner for SPSS:

"Propel research & analysis with a fast and powerful solution"

SPSS is an acronym for Statistical Software for Social Sciences. Its beginnings dates back to 1968 and it was acquired by IBM in 2009. Files created by this software have the extension .sav. SPSS outputs tables and charts that can processed by MS Word, Google Docs, Open Office, etc.

SPSS can be used for editing and analyzing data similar to other software such as R, Excel, Python, etc.

Here is a PR demo from IBM

What kind of data can you work with in DisplayR?

From my previous post you can see that you can really get data from the following kinds of sources:

• Get data by import

    ** SPSS Data Files

    ** SQL Tables

    ** Excel

    ** CSV

    ** Any format that R can handle

SQL tables in SQL Server, SQLite etc are obvious sources of data from relational databases against which you can run SQL Queries.

SQL data is only a small set of data sources which you can use in statistical analysis or author reports.

Here are the various from which you can source your data in DisplayR.

Qulatricss, URL, 

What is DisplayR?

DisplayR  provides two functionalities in a single app.
* Complete Data Science Platform
* Comprehensive Reporting Platform

You create online dashboards and export to PowerPoint & Excel. Since it is cloud based, you have access from anywhere in any browser.

The workflow in DisplayR is similar to other software of this genre.

• Multidimensional Scaling
• Multinomial logit
• NBD Regression
• Ordered Logit
• Poisson Regression
• Principal Components Analysis
• Quasi-Poisson Regression
• Random Forest

• Word Clouds
• Donut Chart
• Labeled Bubbleplot
• Labeled Scatterplot
• Palm Trees
• Pictograph
• Pictograph Bar Chart
• Pie Chart

• CODE
• Huge range of graphical techniques using R

It does all of the above in one step. Well, Power BI can also do this as R is integrated with it and Power BI is also integrated with reporting services. Report update is a nice feature as you can start with a partial set and finish off after importing the whole set. Future updating can be automatic. More importantly, DisplayR has the  'no need for code' slogan.

Here are some main features:

• Quality Control and Reproducibility
• Easy updating and automation
• Simple to create and manipulate variables
• Statistical testing based on data type

You can have an app for free (DisplayR Public) that does a few things, but if you need more advanced features you need to buy DisplayR Professional ($2399/Yr) or DisplayR Enterprise(available on request)

How do you upgrade PIP?

pip is a package management system used to install and manage software packages written in Python. 

I had ae earlier version and I could upgrade it to the latest version using the command in Python.

From the Scripts directory in Python3.7 run the following command:

python -m pip install --upgrade pip

How do you shorten a link reference?

It could happen like it happened to me. You provide a link to your friends in your email and you hear from them saying they could not open.

They may resort to cut and paste the two pieces of what appears to be hyperlinks to get them on a line and save. Many may not go that length and just let you know that they could not open.

The solution is simple by reducing the length of the link. You can do this by pasting your original link (the long one that may get broken) by a short one. This is how you do it.

Go to this URL:

https://tinyurl.com/

Enter your link (the long one) and click Make TinyURL!. That's it. You can get the shortened url below where you entered your URL. This is free and you are not supposed to misuse it.

Now copy that and send it to you friends.

That's it.

I reduced this link which Safari could not open on iPhones/iPads:

http://hodentek.blogspot.com/2018/09/visit-
to-assisi-birth-place-of-st.html

with this one,

https://tinyurl.com/ybyzn4tl

 Google also had one of these tools and it has been discontinued for new users.

February 18, 2021 Update:  20 best URL shortners. Go to link in the image.

There are cases that just one is not enough. Power to choose is democratic.

------------------------------

I have three report servers but two of them have a problem.

If you want to use rskeymgmt you should start the CMD program with elevated privileges as shown:

Once CMD screen is displayed you can find the report servers as shown. I am using the l and i flags in rskeymgmt. The SQL Server Report Server 2012 PCATT has no problem, while the 2016 and 2017 SQL Server instances OHANA and SSRS are showing the same exception.

C:\>rskeymgmt -l -i PCATT   ---SQL Server 2012
HODENTEK9\PCATT - 879ea471-47cf-4386-b7f1-6eb213a5fff6
The command completed successfully
C:\>rskeymgmt -l -i OHANA     ---SQL Server 2016
The profile for the user is a temporary profile. (Exception from HRESULT: 0x80090024)
C:\>rskeymgmt -l -i SSRS      --default instance of SQL Server 2017
The profile for the user is a temporary profile. (Exception from HRESULT: 0x80090024)

The previous result was obtained using a Preview Build of OS that was not working well.

Recently 9/14/2018 there was an update to the OS and things have improved. Here are some new results for the same. 

Two of them are not displaying results, in one case the Database Engine is not running and in the other the Report Server is not running.

Is there a fix for the 'App Didn't Start' error in Visual Studio

This error appears when you try to deploy the project to the Local Machine (x64). There are no errors during build or deploy stages. However, when you try to run the machine you come up with this message after the App shows up momentarily and disappears immediately.

Trying to deploy to an emulator such as Mobile Emulator 10.0.14393.0 WVGA 4 Inch 512MB comes with the following errors. The emulator is running:

Severity Code Description Project File Line Suppression State
Error  DEP0001: Unexpected Error: SmartDeviceException - The system cannot find the file specified. [0x80131500] RMD   

However when you deploy it to a device (in this case Lumia 925) the app gets deployed with no errors.

In order to proceed to package it for uploading to the Windows Store I am not sure just deploying it to the device is good enough.

Is there a fix?

Yes. This was my fix.

https://hodentekhelp.blogspot.com/2018/09/what-is-right-target-version-that-works.html

What is the right Target version that works for UWP project?

I faced quite a bit of downtime due to the wrong choice of the target version working with UWP Projects. Web search to find a cure sent me searching for answers I could not find.

I am using Microsoft Visual Studio Community 2017 Version 15.8.1. The Dell Laptop is running Evaluation copy of Build 17733.rs5_release(18083-1525). [This OS has a problem in that when you shutdown and restart the OS, it will reinstall the OS afresh wiping out some of the folders; saved passwords; saved items in Microsoft Edge. Visual Studio also gets reset.].

Now coming back to the right Target version for working with UWP projects, there are three options for the Target version shown in this image.

RightTargetVersion_0

Of the three options only one of them allows the Design editor in Visual Studio come up without this error - The app did'nt start(HRESULT:0x8027025B). This is the only one that works:

Windows 10 Creators Update (10.0; Build 15063).

Regarding the choices for the Min Version, Build 15086 and Build 15063 works without any changes, just the Solution refreshes.

RightTargetVersion_2

However, if you were to choose Build 14393.0 you need to install the required SDK.

RightTargetVersion_1

These findings are summarized in the next image.

RightTargetVersion_3

How do you use the 'calendar' module in Python?
