One of the nice things about the .NET web environment is the dead easy way to implement Single Sign On in your web apps through Active Directory authentication. In the Java world there are multiple alternatives to use Windows’ Single Sign On with Java based web apps. One of those alternatives is Waffle . Waffle allows your Java web app to authenticate against Active Directory groups (and users). The only caveat is that your web server needs to be running in Windows, which kind of makes sense. In this article, you will learn the steps required to have your OpenXava web application use Waffle to authenticate your Windows users. The first step is to download Waffle from their site and then copy the JAR files outlined in https://github.com/dblock/waffle/blob/master/Docs/tomcat/TomcatSingleSignOnValve.md to the OpenXava’s tomcat server. In your OpenXava project, create servlets.xml in the Web-inf, containing the following: <!-- the role name (the domain gorup) must be e...

Data Science for Business is a book that makes a phenomenal job teaching the fundamental concepts of Data Science (a.k.a. Data Analysis and Data Mining). Foster Provost and Tom Fawcett explain in plain English, clear examples and beginner-level math the processes surrounding Data Science and the basics of its algorithms. The authors go over the various steps of the CRISP method using situations found in the real world such as Customer Churn and Online Advertising. The most common data analysis models are reviewed and explained in detail such as Clustering, Decision Trees and Support Vector Machines. Extensive explanation is given to the difference between supervised and unsupervised methods. Even if you use software tools that create those models, this book will help you understand how to use/test them correctly and how to avoid over-fitting. Multiple examples are given in each chapter and most of the math is visually aided with graphs. The authors explain step by step any eq...

How to make Micorsoft SQL Server's integrated security (SSPI) work in Spoon: Download the MS SQL JDBC sql drivers Copy enu\auth\x64\sqljdbc_auth.dll to {spoon installtion folder}\libswt\win64 Copy enu\auth\x64\sqljdbc_auth.dll  to {spoon installtion folder}\libswt\win32 Copy C:\sqljdbc_4.0\enu\sqljdbc4.jar to {spoon installtion folder}\libext\JDBC Open Spoon When creating the data source, make sure to check "Use integrated authentication" Please note that you are copying the 64 bit version of sqljdbc_auth.dll to both \libswt\win64 and \libswt\win32 if you have a 64 bit processor.

The following Powershell script can be used to send an email alert when a file is missing from a folder or it is the same file from a previous check: $path_mask = "yourfile_*.txt" $previous_file_store = "lastfileread.txt" $script_name = "File Check" ###### Functions ########## Function EMailLog($subject, $message) {    $emailTo = "juanito@yourserver.com"    $emailFrom = "alert@yourserver.com"    $smtpserver="smtp.yourserver.com"       $smtp=new-object Net.Mail.SmtpClient($smtpServer)    $smtp.Send($emailFrom, $emailTo, $subject, $message) } Try {    #get files that match the mask    $curr_file = dir $path_mask |  select name    if ($curr_file.count -gt 0)    {        #file found        #check if the file is differe...

I would like to first set the scope of this article; this is about abortions in cases where the couple had consensual sex and there is no life-or-death health risk to the pregnant mother. In regards to cases of rape or life-or-death risks to the mother, I think it is best for a panel of women (both pro-choice and pro-life) to discuss it. The panel should include people who have gone through those situations and who have taken either direction. No man (pro-choice or pro-life) should be included in that panel and meetings. I also want to clarify before we being that I am pro life in that I believe life begins as soon as the baby starts forming in the womb. Having set the scope of this article, it is important to address the fact that it is very important to point out that when a baby is conceived, the couple is pregnant  not just the mother. The responsibility falls to both the man and the woman. Paying child sup...

I was looking for an ETL software similar to SSIS that would allow me to easily move data from SQL Server to PostgreSQL. I tried using SSIS, but I was never able to make BIDS generated the schema of the destination table automatically like it would do with a SQL server destination table. I downloaded Pentaho’s Spoon data integrator and it surpised how easy it was to do it there. The designer is somewhat similar to BIDS. You drop your input tables (from SQL Server) and then you drop your destination tables (PostgreSQL tables). The good thing is that you do not need to create the tables in PostgreSQL beforehand. You just need to create the destination database. When you open the properties of the Table Output, you can enter the name of the new table and then do the following to create the table based on the data input: Click “Database Fields” Click “SQL” Click “Execute” That’s it. Your table will be created in PostgreSQL using the correct data types. Pentaho’s Spoo...
