Danube river cruise and the Melk Abbey

We went from Vienna to Dürnstein, after about an hour or more of bus ride. We did some sightseeing of this town with the fabled blue church over the hill and 16th century residences. It was typically a town for tourists with lots of shops, restaurants, wine shops etc. on both sides of narrow, cobbled streets. We then boarded the boat at Dürnstein pier at the foot of the hill around 10:00 AM. The ride was for about 3 hours or more and the boat had an on-board restaurant. At a distance, you can see the castle now in ruins that had held Richard the Lionheart captive.

Later we visited the Benedictine Melk Abbey (Lower Austria) adjacent to the Wachau Valley. It has the tomb of the past rulers and a library with a huge manuscripts collection. We also visited the blue gallery and enjoyed the projected slide show on the walls of the museum. on the way to the the Melk Abbey we saw from the boat the ruins of a castle where the Richard of Lion heart was imprisoned.

Wachau valley is well known for its vineyards and wineries. We visited one of them and were served wine ex-gratis...

Using AngularJS on the localhost

AngularJS directives are extensions of HTML markups. They are one of several components of AngularJS. Directives can be attributes, element names, CSS class etc.

AngularJS script reference is important and the script can be found here:

https://ajax.googleapis.com/ajax/libs/angularjs/1.2.25/angular.min.js"
The above script reference needs to be added to your hTML page.

You can find the whole list of directives here:
https://docs.angularjs.org/api

Here is the usage of some directives placed in a html page that can be displayed on your localhost (in this case the IIS in Windows 10). Place this code with a suitable name in the inetpub / wwwroot directory.

======================


  Some directives in AngularJS

ng-app
Sorry, blogger still does not support the "pre" tag!
==============
When viewed on the browser (in this case Microsoft Edge), the HTML page renders as shown.


Do the following on this interactive page:
  • Type anything it gets copied next to Hello
  • Enter the increment region with your mouse, the count (presently 1) gets incremented
  • Click the link and you get to the page
Directives used in the page above and their description:
ng-app: initializes an AngularJS application
ng-model: binds the value of HTML controls (input, select, textarea) to application data
ng-init: initializes application data
ng-mouseenter: an AngularJS mouse event as a cursor moves over an dom element
ng-href: supported by the "a" tag and should be used when AngularJS code as in the example

Vienna is synonymous with Klimt

We could visit quite a few places. It was a very warm day and one can get quite tired.

  • Rococo style Schönbrunn Palace (UN Heritage Site) and its environs
The palace museum is huge and it reflected the opulence of the times. Room after room filled with art objects; huge mirrors; chandeliers and paintings.

  • Ringstrasse
  • Goudi styled Hundertwasser haus - Out of the ordinary, fairytale
  • Leopold Museum
  • Mozart Statue in the Palace grounds
    Albertina Museum
    Shopping, Karlsplatz  etc
Here are some slides of the day:

A must place to visit near Budapest


We visited the picturesque town of Szentendre on the bank of Danube in Hungary not too far from Budapest. It is easy to reach there by bus. It is truly picturesque as you see in the pictures and if you are into painting you may like to visit. It has a beautiful church and there are restaurants although we did not eat there.

We visited this town during our recent trip to Europe and spent a delightful hour there on the way from Budapest to Vienna. Later we travelled to Vienna...

Arriving in Vienna we went out although it started getting dark. The subway (metro) is clean and convenient. Karlsplatz was where we headed to...

Bend in the river Danube and the river cruise at night


It was more like a free time in Budapest.

We visited the World Heritage listed Gellert-Hegy (Hills) from where one can see the bend in the Danube river. The panoramic view is great. It was somewhat a hot day in June but it was quite breezy. We went up part of the way in a taxi (about 5 Euros) and came down in a bus. About half a mile from the hill top there was a fine restaurant that people go on special occasions. It was quite nice.

We looked forward to the boat ride in the night but half way during the cruise it started raining heavily. After the cruise we took a taxi to the hotel as it was still raining and somewhat dark.

Here are some pictures of the day:

Touring Budapest, Hungary by bus

Into the 3rd day of our European visit we toured Budapest by bus. We had a local guide who spoke reasonable English. Our tour director spoke English, German and Czech.

Touring a city by bus (Inside the bus) has advantages as you cover many places. The downside is you miss 'your feet on the ground' and the opportunity to look at things from a couple of directions. If you are some what hard of hearing and the sound system is less than adequate, you miss a awful lot of information the guide is giving.

Here is a short list of things you see in a day tour
House of Parliament
The Chain Bridge
St. Stephan's Basilica
National Opera House
The Central Market
Fisherman's Bastion
The river Danube
Holy Trinity Square

Here is a slide show video of our tour:

Visit to Salt Mines and the Bavarian Alps


We left Arcotel Castellani early after breakfast around 8:00 AM in our bus. It takes just 30 or 40 minutes to reach Berchtesgaden in Bavaria, a mere 16.6 miles from Salzburg. This area is famous for its salt deposits and provided a rich commodity and a source of revenue for the people in ancient times. Because of this it was occupied by France, Austria(Salzburg) and Germany.

The visit to the salt mines was interesting. You need to purchase tickets to enter the Salt Mines and the shop. Shop alone is free where you can buy salt related products. You must wear the proper attire to the mines which you can wear over your clothes and store your other items in the lockers (2 Euros which will be returned). After wearing the special over clothes, you wait your turn to ride the rails. This was an interesting experience. However, there are also walk ways and staircases. After reaching the bottom of the rails you cross the subterranean salt lake in a boat with other visitors to visit the gallery in the museum. It is pretty well done with lots of stuff to see how salt was recovered and brought to surface for commercialization.

There appears to be a slat mine health resort, 'Heilstollen' where you can find relief for several kinds of ailments.
Berchtesgaden was also the holiday retreat for Hitler and his lieutenants. The Kehlesteinhaus (Eagle's Nest) atop the Kehlstein peak was a present to Hitler for his 50th birthday. We will visit the Eagle's Nest after visiting the salt mines

"Salt is the most valuable gemstone given to us by the earth." 

Justus von Liebig (known as the greatest chemistry teachers of all times)
https://www.britannica.com/biography/Justus-Freiherr-von-Liebig

Before embarking our journey to the Eagle's Nest, we had breakfast/brunch/beer/coffee at one of the smaller towns on the way. The bus to Eagles Nest takes you to an intermediate point after which you take a specially fitted bus to go another intermediate point. From here you take enter the tunnel to the elevator shaft. You then ride up to the disembarking area to walk to the Eagle's Nest. The view of Bavarian Alps from here is unforgettable. Cameras can only capture a fragment of this beauty.

Here is a slide show of this visit. Come back here later as I plan to upload at least one video.

Sightseeing in Salzburg, Austria



This is day 12 of our European tour and it was as exciting as it was tiring. We stayed at the Arcotel Castellani, Salzburg . It was quite comfortable and the breakfast was OK.

The Mirabel garden soon after the lifting of  rain was most beautiful, perhaps at its best. The city is divided by the river, the old town and the new. As is always true the old city is where you go and see most of the things. The house where Mozart was born is always crowded. Tourists milling around most of the times. The cathedral is very nice.

The 17th Century Roman Catholic Cathedral is another place you must visit. It was here that Amadeus Mozart was baptized (very obvious, the house where he was born is not too far). The Cathedral is dedicated to St. Rupert and St. Vergilius.

The Hohensalzburg castle is another place you must visit. You need to go up in a cable car and it is pretty steep. There are restaurants in the intermediate stage. The view of the city below is nice and keep you busy taking pictures.

Viennese Coffee at Tomasellis was quite good. We sat out on the terrace, but you can also sit inside the restaurant which retains some old décor.

The shopping district is never too far with lots of restaurants. I did find an Indian Restaurant run by a Punjabi and food was quite good. It was not purely Indian, you could have Italian as well as Mexican.

Here are slides from that visit.

Visting Český Krumlov on the way to Salzburg from Prague - Day 11

Český Krumlov is on the World Heritage list 1992. It is very beautiful with the castle, the monastery, and the gardens. A place you must visit if you are anywhere near Prague or Salzburg. Its early owners were Germans later acquired by Czechs.

You must see to believe how beautiful it is and the next best thing is to see its pictures on the Internet.

This one is a slide show of pictures taken with iPhone 6S and Lumia 950.

Hands-on Learning Event in Honolulu 1 : Introduction to Structured Query Language


Course summary:

Databases - organized repositories of information have become indispensable. Knowledge of databases is a must for professionals and in fact even more relevant since the emergence of Big Data in today's world.

In this introductory course you will learn all about relational databases and the basics of Structured Query Language (SQL) including sorting; grouping result sets; using DDL, DML, DCL, and TCL. All SQL statements will initially be written for one table. Most practical, modern and relational databases will include a large number of tables and SQL queries have to access information from several tables. This course will then introduce you to querying more than one table. With this skill you will be able to query two or more tables in a database. This is a hands-on course which will take you from installing SQL Server 2016; learning the ins and outs of SQL Server Management Studio and of course a full dose of SQL. You will be both coding as well using Graphical User Interface during this training.

During each meeting the students will be assessed for their knowledge, competency and proficiency in SQL.

Prague a beautiful city

Prague is a historic place with lots of church spires and Baroque architecture; a city cut in two by the Vltava river. Charles Bridge connects the two halves, the old town and the new. It is a truly beautiful city with ancient churches and history dating back to the Roman Empire. We had an optional tour to visit, a walking tour of Jewish Quarters. We missed it as we wanted to see more of the city.

Deep learning AI with Caffe2GO

You create a video and you want it the way Picasso or Monet would have visualized it. Can it be done? The answers appears to be answered by Facebook's Caffe2Go. It was easy with stills as many programs do it, but with a video it is another thing.

Caffe2Go is supposed to be third iteration of AI, the deep learning. This was possible earlier with big machines and lots of computing power, since the program has to learn the myrid images that these great artists envisioned it could not have been done otherwise. But to do it on the phone in the palm of your hand, that is something that Facebook seems to have pulled off, with the Facebook app Caffe2Go.

It is a deep learning platform on the mobile phone. The app takes the style of the artist and transforms the input video, it is basically a style transformer.

Here is a demo of this deep learning app:

Creating Full-Text Catalog in SQL Server 2016 SP1

A full-text catalog is a logical container where a group of full-text indexes are stored. A full-text catalog is needed before you can create a full-text index. Full-text catalog is a virtual object and does not belong to the file group.

In order to text search a full-text index will be needed. For example, the Categories table in Northwind does not have a full-text indexed column. If you try to create a Full-Text indexed column you will get this error:
-----------
Msg 9967, Level 16, State 1, Line 11
A default full-text catalog does not exist in database 'Northwind' or user does not have permission to perform this action.

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

You can create a Full-text catalog using the SQL Server Management Studio or using Transact-SQL(T-SQL)
---------
Here is how it is created for Northwind database in SQL Server 2016 using T-SQL

USE Northwind
Go
Create FULLTEXT CATALOG ftCat_Nwind as default
Go

------
Before the above statement was run there was no Catalog:


After the above statement was processed the named catalog was created:


You can access the properties as shown here

All tables and views are eligible and you can assign the objects to the Catalog by transferring using the > button.

Creating a Full-Text catalog for Northwind using SQL Server Management Studio is easy. Right click Full-Text Catalogs in the Storage node and provide a name for the catalog and a owner. Choose the accent sensitivity and click OK to create.


The Catalog gets created as shown.

Is this the end of the story? No

Caution:
Although SQL Server 2016 SP1 allows you to create a Full-Text Catalog, you will find it missing in the System Views as in the following query.

This feature has not improved even from the older versions. It has not been fixed and the error messages that you get such as the following does not give a clue.

Property IsAccentSensitive is not available for the Full-Text catalog <catalog name>
Property PopulationStatus is not available for FullTextCatalog <catalog name>

The reason for this error is that the Full-Text feature was not installed in the first place.
Watch the video and review features not installed:

BitLocker behaving badly

This is the classic example of getting out of one problem and getting into another.

I had the virus problem (probably the ransomeware except that I did not click on any link and the threatening page did not go away after a reboot, etc.) on my Toshiba tablet with Windows 10 and decided to System Reset to clean the tablet. It went through the process and now requesting entering of a recovery key. There is a Key ID on the tablet (8 alphanumeric characters) and if I try to enter I get a basic numeric keypad like on a calculator with keys marked with only numbers.
It may work if I can enter. But how can I enter this 8 character ID using this calculator-like numeric keypad? and Drive Label with a date.



The tablet is on a Wi-Fi network with 3 other laptops (two running Windows 10 Pro and the other Windows 7 Pro)

It turns out that I am supposed to have a key and what was shown above was the KeyID (only the first part of it). The key itself is all numeric with 48 characters.

Finally I used the manage-bde commandline command to see what is going on.
Finally using manage-bde, I could find out that I have only the recovery key id without a recovery key.


What surprises me is that I never meddled with BitLocker as I do not have great secrets to guard. How come the BitLocker was locked in the first place? I toook the tablet to the Microsoft Store where they might be able to find some thing.

 It is not I don't have a key, I believe there never was one!

It is still puzzling, that since I did not lock the machine with BitLocker, who did?

According to Microsoft Store, when I signed into Microsoft Account the BitLocker by default locks it. It did not seem credible to me. I did not get the impression the technician was fully conversant with BitLocker. I avoided BitLocker for the simple reason, I did not want another layer of complexity to my files/folder that do not contain sensitive information.

One of the members of Microsoft Forum provided some background information of BitLocker's evolution. This is what might have happenned (his words):

"Earlier, Microsoft used to enable bitlocker on the home version of windows if
A a microsoft account was used
B the computer fulfilled the hardware requirements (TPM chip, instant-go compatible).
That was quite an idea... they even shot the recovery key through the network in plain text - some german IT magazine ("IX") discovered that. By now, they stopped it."

Microsoft's Globally distributed database, Azure Cosmos DB

"Azure Cosmos DB is Microsoft's globally distributed, multi-model database. With the click of a button, Azure Cosmos DB enables you to elastically and independently scale throughput and storage across any number of Azure's geographic regions. It offers throughput, latency, availability, and consistency guarantees with comprehensive service level agreements (SLAs), something no other database service can offer"

If you are looking for Global Distribution, horizontal scaling, guaranteed latency, high availability, comprehensive SLA's and unrivalled Data Model and APIs that no RDBMS, no no-sql database can provide, there is nothing out there to match Azure Cosmos DB.



Azure Cosmos DB Engine supports multiple database systems and it is based on the following:

 Atom: Consisting of a small set of primitive types (String, Bol, number)
 Records: Structs
 Sequence: Arrays of atoms, records and sequences

Azure Cosmos DB engine currently supports the following:

Document DB SQL
Mongo DB
Azure Table Storage
Gremlin Graphh Query API
It will support other API's in the future.

For developers looking for a globally distributed database system Azure Cosmos DB is the answer.

This is how you save a report authored in Power BI to a Report Server - Final

I apologize to the readers of my post,Can you save reports created in Power BI to a Report Server?  for having given the wrong impression. The reports you create cannot be saved to any report server but the stand-alone report server created using the same .msi file downloaded from the same location where you downloaded Power BI Desktop Technical Preview.

I am only partly to blame for this and I apologize. Let me correctly present what kinds of reports can be saved to what kind of report server. The other reason for the problem was created by the Power BI itself for giving the wrong guidance for the users while saving the report to the report server. It must be changed.


  • The only kind of reports that can be saved to Report Server (strictly speaking, you are only saving it to the Web Portal URL) are the ones created with data from the Analysis Services server.
  • In order to save you need to configure a stand-alone Report Server whose database is stored not on a SQL Server 2016 but an earlier version. In my case I use the SQL Server 2012. The .msi file for this server is on the same download site as the Power BI Technical Preview.


After you fulfill the above conditions then only you can host the report.


I was able to get the correct server by an answer to my question on StackOverflow.com.

From PowerBi to Report Server, the easy way

If you use the Technical Preview version of Power BI Desktop. You can save reports to your on- premises SQL Server.

 NOTE: If you already have configured a SQL Server 2016 Reporting Services server you will not be able to upload the reports from Power BI. You need to install the SQLServerReportingServices.exe mentioned below and configure a Standalone SQL Server Reporting Services which will provide a http://<domain>/ReportServer.

You can download this for both x32 and x64 versions. With this you can,


  •     Connect “live” to Analysis Services models – both Tabular and Multidimensional (cubes)
  •     Visually explore data and create an interactive report
  •     Save that report to your report server running the Technical Preview
  •     View and interact with the report in your web browser

If you do have Power BI for Desktop on your computer you still need the (January 2017) Technical Preview. This can sit alongside your present Power BI.
=====================

How do the File Share account settings are used in SQL Server Reporting Services 2016?

This is feature is applicable only for Native Mode.

In order to specify a single file share account ( a new feature of SQL Server 2016) you must get to the Subscription Settings page of the SQL server 2016 Reporting Services Configuration Manager shown here.


The file share account that you set up here allows you to set a single set of credentials in multiple subscriptions that deliver reports to a file share.

When you want to change credentials you just change the credentials of the file share and you need not change the credentials of every subscription in the shared folder. In the subscriptions in the file share each subscription will specify; Use file share account.

However you may also configure individual subscriptions with specific credentials as well or, have some on file share and some with individual specific credentials.

Author your first report using SQL Server Mobile Report Publisher

This post is about displaying a Mobile Report created by the SQL Server Mobile Report Publisher after publishing the report to a SQL Server Reporting Services which is actually the Web Portal URL of the Reporting Services.

The present Reporting Services configuration is pertinent to SQL Server 2016 Reporting Services on the local machine.

While it should also be possible to publish it directly from the SQL Server Mobile Report Publisher, it was not possible because there were errors connecting to the Report Server although the SQL Server 2016 Database Engine; the Reporting Services were all up and running and an empty folder 'Reports' was created on the Web URL. I have not tried to verify the problem yet. This could be because of the constant upgrades coming to the OS automatically.

In this post, I consider uploading a report to the Web Portal URL after saving the file created by the SQL Server Mobile Report Publisher to a local folder.

You need to make sure the Reporting Services database is accessible which the same as the SQL Server Database Engine  running; the Reporting Services has started and the Service and Web Portal URL have no problems.

Then use the Upload button on your Web Portal URL to upload the report created and saved (to local file system) to the computer. Once it gets uploaded the report gets into the WEB Portal URL as shown.




The Northwind Report has three charts, the creation of one of them is detailed in my earlier post here. I have just added two more grid items this upload.




You can view each of them on the WEB Portal URL as well as shown here.

Finally the TOSHIBA DVD/CD-ROM drives problem is fixed

Quite a long time ago I reported in my post regarding the loss of DVD drive. I use the DVD very infrequently and it was on the back burner. Finally I decided to get to the bottom of it and succeeded. Here is the result.

In the Device Manager I could see that the DVD device was not working properly as reported in the previous link. The Toshiba, TSST Corp CDDVDW SU-208DB drive was not working and the DVD drive was not seen in the Windows Explorer. The properties of the problematic drive appeared as shown with the Code 19 error (image from the above post).


Finally I came across this Toshiba support site here.

Interestingly this page does not say anything about Windows 10 but describes the fix for Windows 8
My problem started when Windows 10 anniversary update was made and the DVD stopped working from that time.

The fix for this problem consisted of removing two of the programs from the Control Panel|...|Programs and Features shown here:

Toshiba Recovery Media Creator
Toshiba Disk Creator


and also uninstall the DVD\CD_ROM Drives element in the Device Manager.

I did not have the Toshiba Disk Creator, but I uninstalled the TOSHIBA Recovery Media Creator and the DVD/CD-ROM drives in the Device Manager.

These are as shown in the screen shots:


DVD-000


DVD-001

And now after restarting the computer I can see the DVD drive in the explorer.

Firefox 51.0.1(32Bit) on Windows 10 Pro build has this new problem.

Your browser is open and, you have couple of other windows (notepad, Microsoft Edge, Excel, etc) open and all of a sudden the window display is frozen. You click here and there but no reaction. How do you get out of this?

The only way I have found is by invoking the Task Manager. As soon as Task Manager comes up the problem goes away this time around, and you can bring to the top any window you want. It can happen again.

Who is the culprit?

I am not sure if it is the OS () or the Browser. I have seen this happen with Microsoft Edge as well. Probably it is OS build that is the culprit.

OS Version used here:

Version 1703

Build: 15063.0

Windows 10 Professional

Build web apps with R studio

 R language is open source with a huge number of developers. It has a great arsenal of great stuff already accomplished. It is a language that you should get exposed to yourself. You just install R Gui and you are ready.


Shiny is an enterprise-grade web application framework targeted for those who want to develop with R using the familiar HTML5, CSS and JavaScript. Using R you can turn terrific analytic solutions you have developed/developing into interactive web applications.

Go to this site (https://shiny.rstudio.com/) directly and learn more.

 
Rshiny-00

If you have R Studio you have Shiny because Shiny is a package that you can download.

In this first part we only talk about the very basics.

I assume you have read my previous hands-on R examples in my blogs.

http://hodentekhelp.blogspot.com/2015/09/what-is-good-way-to-learn-r-language.html
http://hodentekhelp.blogspot.com/search?q=R+language

Here I just show a very basic (aka Hello World) example of creating content for a web page using R GUI. More will come later in my blogs.

Launch R Gui as shown and provide reference to the shiny "library" as shown by typing in the three lines of code (The four lines of code in red).


 HelloWorld_00

When you hit Enter after the third line where you define the shiny app, a browser window will open as shown displaying the apps output as shown at a port of the local host.



HelloWorld_01

You also get a response (the last line) in the R GUI as shown.




HelloWorld_02
That is all there is to create a content.

The ui summarizes your user interface, the server is something like a web server and shinyApp is your web response. No fuss, very simple.

Take a look at some of the nice apps with SHINY here.

Install and use the new Report Builder 3 with SQL Server 2016

Download Report Builder 3 for SQL Server as described in my previous post .

You will have downloaded the ReportBuilder.msi file published on 3/9/3017. Note that there are other Report Builder.msi related to other versions (for example ReportBuilder.msi for SQL Server 2014 etc).

The installation is driven by a wizard and it installs without any problem. You need not indicate a Reporting Services Report Server during installation.



Here are screen shots of the installation:

Welcome Screen


License agreement window. Click I Accept...


 It will be installed on the local hard drive. Note that this product may also work with SQL Server vNext CTP1.3.


SQL Server 2016 reporting services has two modes and you need not have these installed and configured. You may keep this empty. Click Next.


Click Next and you are ready to install.


 Click Install. Begins installing with a progress screen.


 It is done installing.


 You should see these in All Programs on Windows 10.


Double click and you are ready to Author a report. If you want to put it out on the Report Server, you need a Report Server.

You are ready to go!

Arris dual-band router

A dual-band router is a router that has two bands.

For example, the Arris router used by subscribers to Time Warner Oceanic service provider uses the service provider provided router that two has bands, 2.4 GHZ and 5 GHz. This router has functioned well from the time it was installed. Before this I had a single band LinkSYS router.

A typical dual-band router has an administration panel shown here:


You can see that you can have separate settings (password, encryption, etc.) for the 2.4 GHz and 5 GHZ bands that this router can provide.

You can have devices working with either of these two bands or both. For example one or two of desktop works on 2.4 GHZ and my Lumia 950 on 5 GHZ.
My Samsung TV works on the 2.4GHZ as well.

If want to utilize the full power of bandwidth, or have multiple devices that depend on Wi-Fi it may be better to go to dual-band router although they may cost higher.

Get a handle on financial portfolio analysis using R

I read a very illuminating article on R-Bloggers which was originally published on R-Curtiss Miller's Personal Website.

Ever since Microsoft SQL Server began supporting R in its 2016 version, I got interested in R language. It is extremely rich with wide applicability from Astronomy to Zoology and everything in between.

Financial information from Yahoo as the source, the package 'quantmod' brings with it most of the useful financial information related functions about stocks. quantmod gets data from Yahoo Finance and Google Finance plus data  from other sources.

In order to work with financial data you should download the package which can done as shown:
------------
> # Get quantmod
> if (!require("quantmod")) {
+     install.packages("quantmod")
+     library(quantmod)
+ }

Loading required package: quantmod

It covers the whole globe and the global developer view shows how many in these countries are part of the global developer community.

Here are the various sub-categories of the survey breakdown.

The salary related data should be very interesting for those who want to pursue a career. Things could be different in 2018.

JavaScript appears to be the king.

Hyperloop One - Setting up the tracks

Since my first post in 2013 things have moved up a little bit. According to this news item, the start up company Hyperloop One (not an affiliation of Elon Musk's business) has begun constructing a full-scale test track called the DevLoop in the Nevada desert. According to their one liner, Hyperloop One has promised to deliver a means of transit that offers airplane speed at bus ticket prices.

You know what, this was unveiled appropriately in a Middle East Rail Conference in Dubai.  It appears the first implementation of Hyperloop may take place connecting Dubai with Abu Dhabi. Well this is a very hopeful choice with Dubai having a lot of cash and a wide open desert. There is lot more of this news at this NBC's news site.

Read at Hyperloop One here for the full story:

Here is a You Tube video :


Traffic congestion is a major, major problem and any thing to mitigate its effects such as lost time, pollution, stress at a reasonable cost is worth the effort & justifies support.

India  has teeming millions with cities congested with traffic beyond imagination and unbelievable pollution. No wonder India is looking at this technology although bringing Hyperloop India will not be easy.

2oth anniversay Visual Studio Event - Congratulations

In a matter within the week, Visual Studio 2017 will be released (March 7). I cannot help but recollecting the journey, I had with Visual Studio.

I started using Visual since the day 1 it appeared. Actually I was attracted by the Visual IDE even earlier with Visual Basic, Visual InterDev (the precursor for Visual Studio) and all the other Visual programs from Microsoft.

I also used Visual InterDev for some projects at WorldCom. Neither Visual InterDev nor I had anything whatever to do with whatever happened to WorldCom (http://www.cbsnews.com/news/world-class-scandal-at-worldcom/).

I was teaching out of work folks during the bubble period who were eager to acquire Web related technology that can access back-end databases. They loved it all, although Visual InterDev had a long way to go.

Later on I had a lot to read up on Visual Studio for the five books I wrote from (2007 to 2012). They are all displayed on my blogs. They really helped me to write as the software was available free. In order to get a free copy, distributed in one of the Microsoft events in Long Island, NY I traveled from Princeton to Long Island and did an overnight stay.

Wish you a very happy birthday Visual Studio and many more birthdays to come.
I have blogged extensively on Visual Studio about all versions in four of my blogs. Review the following:

Bacpac file on GitHub can also be used to construct Wide World Database on SQL Server 2016

In my previous post I showed you how easy it is to bring the Wide World Importers (WWI) database into a named instance of SQL Server 2016 SP1 on your computer(desktop / laptop).

In this post I describe how you may construct the database on the named instance using a BacPac file.
If you have not used this kind of file please review the following link here.

In what follows I describe using the .bacpac file to construct the WWI database
Go here:
https://github.com/Microsoft/sql-server-samples/releases/tag/wide-world-importers-v1.0

Get this bacpac file:
Azure SQL Database Standard tier

    WideWorldImporters-Standard.bacpac - standard edition OLTP sample database in bacpac format. For Azure SQL Databases in the Standard tier.


Download the 58.4 MB file from the above site.


SQL Server 2016 SP1 like the other versions has a wizard to bring the database using a .bacpac file such the one you downloaded.

You invoke the wizard as shown in the next image and follow through.


bakpacWWI_01.png

Click Import Data-tier Applicaiton... to open the window shown in the next image.  Read the steps in this introductory page.


bakpacWWI_02.png

 Click Next. You click the Browse... button to locate the  indicated file. This is the location to which I saved the WideWorldImporters-Standard.bacpac file. 
It does not matter it is for Azure SQL Database.


bakpacWWI_03.png

After getting the file location from the location as shown in the next image proceed to next step.


bakpacWWI_04.png


After getting the file location in the wizard's interface (the image one above the previous) click Next.


bakpacWWI_05.png

 Just verify that the location for files are what you want. Herein defaults are accepted. You could browse and park elsewhere.

The database name was changed to WWI_Bacpac.

Click Next. The Summary of processing is presented as shown.


bakpacWWI_06.png


Click Next. The next four images shows the progress captured in images. Indexes are dropped and created, etc.

 bakpacWWI_07.png
 bakpacWWI_08.png
 bakpacWWI_09.png
bakpacWWI_10.png

Object explorer refreshed - last processing step.

The WWI database is imported successfully.

Here is the final verification of the import into the named instance.

bakpacWWI_10.png

This method of importing the database appears to be slower than the one in the previous post. as there is a lot of processing related to deconstructing and reconstructing the indexes.
