Introducing FugueSQL — SQL for Pandas, Spark, and Dask DataFrames An End-To-End SQL Interface for Data Science and Analytics As a data scientist, you might be familiar with both Pandas and SQL. However, there might be some queries, transformations that you feel comfortable doing in SQL instead of Python. Wouldn’t it be nice if you can query a pandas DataFrame like below: … using SQL? Or use a Python function within a SQL query? That is when FugueSQL comes in handy. What is FugueSQL? FugueSQL is a Python library that allows users to combine Python code and SQL commands. This gives users the flexibility to switch between Python and SQL within a Jupyter Notebook or a Python script. To install FugueSQL, type: To run on Spark or Dask execution engines, type: In this article, we will explore some utilities of FugueSQL and compare FugueSQL with other tools such as pandasql. FugueSQL in a Notebook FugueSQL comes with a Jupyter notebook extension that allows users to interactively query DataFrames with syntax highlighting. To use it, import the setup function from fugue_notebook to register the%%fsql cell magic. This is only available on classic notebooks for now (not available on JupyterLab). To understand how the%%fsql cell magic, let’s start with creating a pandas DataFrame: Now, you can query like how you would normally do in SQL by adding the %%fsql at the beginning of the cell. In the code above, only PRINT does not follow standard SQL. This is similar to the pandas head() and Spark show() operations to display a number of rows. Operations such as GROUP BY are similar to...

Cyber-attacks against Estonia in 2007 pushed Estonia at the front line of cyber security. One of the results of this cyber-warfare was the wide acknowledgment that cyber security knowledge and skills are part of the information society’s blood circulation. Today we can report that the Centre for Digital Forensics and Cyber Security at TalTech provides the highest level of cyber security education…starting from first-graders! Arena for strong cooperation with the world’s best In general, TalTech’s Department of Software Science, especially its Centre for Digital Forensics and Cyber Security, is materializing the ambition to be the best provider of cyber security bachelor, master’s, and doctoral education in the Nordic countries and the Baltics. Several factors support it: Estonia’s history in leading the mindset that cyber security must grow along with the digitalization of the society; establishment of NATO Cooperative Cyber Defence Centre of Excellence in Tallinn; support from the Estonian Ministry of Defence and a vast network of enterprises that are developing top-end cyber security solutions.

To ignore even one of the three is inviting disaster. Therefore, we tackle the topic from the...
With the release of .NET 6 there are even more benefits to using ASP.NET Core. But migrating existing code to ASP.NET Core often sounds like a big investment. Today we’ll share how you can accelerate the migration to ASP.NET Core. There are minor changes you can make today that can make it easier to migrate to ASP.NET Core tomorrow. Before we begin let’s talk about a real scenario. Let’s talk about how to modify code in a 10-year-old application so that it can be shared with ASP.NET Core. In the next sections we’ll give samples that migrate the ShoppingCartController.cs from the MVC Music Store app that was used to demo ASP.NET MVC3. The first step to migrating this web app is to create a new ASP.NET Core Web App (Model-View-Controller) project. This template will add support for Controllers and map the default route for Controllers in the Program.cs file. Once we have the new project setup, we’ll remove the default HomeController and the view files for Home/Index and Home/Privacy so we can share content from the MVC3 Music Store web app without conflict. You can share Controllers The first thing you can share between the two projects is Controllers. Many teams want the new website to work the same as the current one. And when we say “the same” we mean “the same”. If you fix a bug in one project, then you need that same fix to show up in both sites. One of the easiest ways to assure this behavior is to share the same file in both projects. Luckily ASP.NET Core uses the new SDK style...
