PYPTUG Monthly Meeting (October): Altair, Ansible and more

Details

Come join PYPTUG at out next monthly meeting (October 30th 2018) to learn more about the Python programming language, modules and tools. Python is the language to learn if you've never programmed before, and at the other end, it is also a tool that no expert would do without.

Main talk:     Altair
presented by Martin DeWitt

bio:
Originally from Winston-Salem, Martin DeWitt is a former assistant professor of physics, who frequently used Python and IPython notebooks to teach both introductory and upper-level physics courses and labs. He is currently transitioning to a career in data science.

Abstract:
Altair is a statistical visualization Python library designed to facilitate the exploration of data by making it easy to generate interactive web-based visualizations. Using Pandas dataframes as data sources, Altair's API provides functionality to transform data (bin, sort, filter, and aggregate) and produce common graphs including histograms, line charts, scatter plots, and heatmaps. Graphs can be made interactive with features like panning, zooming, and filtering by mouse pointer selections. Most of the aspects of generating the visualizations -- axes, scales, legends, and interactive features -- are handled automatically, only requiring the user to employ Altair's concise declarative syntax to specify the connections between data columns in the dataframe and the various properties of the graph (axes, color, size, etc). With very few lines of code, you can generate rich, interactive, and portable web-based graphs.

In this presentation, I will first briefly introduce importing and viewing data using Pandas. I will then demonstrate some of the features of Altair for transforming data and creating both static and interactive graphs. We will work through a number of examples, step-by-step, from importing the data to a finalized graph. I intend for you to code along with me, so please be sure to bring your laptop.

For those who are interested in how the magic happens, Altair is based on Vega/Vega-Lite, which is a high-level grammar for producing interactive visualizations. "With Vega, visualizations are described in JSON, and generate interactive views using either HTML5 Canvas or SVG."(http://vega.github.io/) Altair works by taking specifications from the user through Python objects, generating the proper JSON code, and then using Vega to add a Canvas or SVG-based visualization to a web page. There are also renderers that allow Vega visualizations to be displayed in IPython and Jupyter notebooks.

PYPTUG Monthly Meeting (September): Introduction to Packet Manipulation with Scapy

Details

Come join PYPTUG at out next monthly meeting (September 25th 2018) to learn more about the Python programming language, modules and tools. Python is the language to learn if you've never programmed before, and at the other end, it is also a tool that no expert would do without.


Main talk: Introduction to Packet Manipulation with Scapy


by Samuel Mitchell

Abstract:

Scapy is a very powerful framework written in Python that allows the forging and manipulation of packets. It's a swiss army knife of sorts for dealing with capturing, interacting, and manipulating packets down to the packet frame itself. It sees a lot of usage in the security community as a result but can also be used by anyone who needs to reverse engineer odd/unique protocols, QA test products at the lowest levels of the OSI layers, or come up with or test your own communication protocol. This will be an intro to the usage and capabilities of scapy targetted at anyone familiar with the basics of networking at the OSI layer and basic Python programming.

Bio:

Samuel Mitchell lived a former life as a sysadmin and in the DevOps field. In his current life, he works as an Offensive Security Researcher/Tester for a large financial institution. He's also a husband/father of three kids, and dreams of some day finishing one of his multitude of side projects.

PYPTUG Monthly meeting: Wrangling Geospatial Data

Details

Come join PYPTUG at out next monthly meeting (June 26th 2018) to learn more about the Python programming language, modules and tools. Python is the language to learn if you've never programmed before, and at the other end, it is also a tool that no expert would do without.

The meeting will start with a back to basics introduction.

Then on to the main talk:



"ArcPy: Wrangling Geospatial Data with Python"


by Laura Tateosian

Abstract:

ArcPy, the Python interface for ArcGIS Desktop/ArcGIS Pro, allows you to work with geographic datasets and invoke the powerful tools that have been developed by ESRI for analyzing and visualizing geospatial. This talk will provide an overview of the functionality exposed by the ArcPy API and demonstrate how these functionalities can be invoked.  Python can be used to invoke any of the built-in tools for processing geospatial data (e.g., finding buffer zones to identify streams near proposed highways, intersecting geospatial data layers to find overlap of historical habitat and urban sprawl, calculating changes in landscapes with raster algebra, and so forth).  Attendees will learn how to interpret the ArcPy help documentation  and how Python can be used to call geoprocessing tools, to programmatically manage proprietary GIS data formats (list and describe the data), read and modify proprietary data formats such as shapefiles with arcpy, work with ArcGIS map documents, generate custom ArcGIS GUIs. 

Bio:

Laura G. Tateosian is a professor at the Center for Geospatial Analytics at North Carolina State University where she leads an active research program in geovisualization and recently authored a textbook on Python for ArcGIS. Her lab works with geoparsing, eye trackers, and open source web mapping and visualization tools to investigate plant disease spread and human trafficking and to develop innovative digital reading environments. She earned her B.A. in Mathematics from Towson University, her M.S. in Mathematics from the University of Oklahoma, and her Ph.D. in computer science from North Carolina State University. She teaches Python Geospatial Programming and Geovisualization in the Geospatial Analytics Ph.D. and the Master’s in Geospatial Information Science and Technology.  She has traveled extensively and likes to body surf.

Main Talk: How to Plan to Migrate to Python 3
by Philip Semanchuk of PySpoken LLC
Bio:
I started writing BASIC on a TRS-80 and have been building software ever since using everything from C to Visual Basic to Python. For the past several years, I’ve been a freelancer focused on Python, especially where it meets C and other compiled languages but also for Django work. Some of my clients are Fortune 50 companies and others have just a handful of employees.
In the past, I have given talks at PyCarolinas, PyOhio, PyData, and the Triangle Python Users Group. This is my first opportunity to speak to the Python Piedmont Triad UG, and I’m grateful for the invitation.
Currently I’m using Python to perform etymology-focused lexical analysis. It’s a subject I know very little about, so I’m glad NLTK exists to hold my hand! Later this year I hope to use Python to collect data from a photovoltaic solar system that’s installed where I live.
You can learn more about me at http://PySpoken.com where I also have a blog (http://blog.PySpoken.com)
Abstract:
Python 2 will no longer be supported past 2020, yet many organizations still haven't made the switch to Python 3. This talk is for anyone facing a 2-to-3 migration that they'd like to feel more confident about. Attendees will leave with the outline of a migration plan, some suggested focus areas, a knowledge of helpful tools, and links to resources they can use after the talk.

 Detailed Abstract

Many organizations haven't yet made the switch to Python 3. Time is running out for them since Python 2 will no longer be supported past 2020. Organizations with larger projects to migrate will need to start very soon in order to meet the deadline.

Migrating from 2 to 3 can seem overwhelming, but it doesn't have to be if you make a plan, take it step by step, and use the right tools. What's more, there's a great deal you can do immediately (while still in Python 2) to make your code more compatible with Python 3.

This talk is for anyone facing a 2-to-3 migration that they'd like to feel more confident about. The talk will discuss five areas of focus -- choosing a Python 3 version, identifying test gaps, reviewing dependencies, prepping one's code for Python 3, and the actual switchover. I'll discuss strengths and weaknesses of the tool `caniusepython3` for assessing dependencies. I'll also go into a fair amount of detail on Python's tool `2to3`, including how (and when) to use it effectively.

**Attendees will leave confident that the migration is manageable.** They'll have the outline of a plan, some specific areas on which to focus, a knowledge of helpful tools, and links to resources they can use after the talk.

PYPTUG February Monthly Meeting: VPython (3D Programming for Ordinary Mortals)

Come join PYPTUG at out next monthly meeting (February 27th 2017) to learn more about the Python programming language, modules and tools. Python is the ideal language to learn if you've never programmed before, and at the other end, it is also a tool that no expert would do without.

 

Main Presentation:

VPython: 3D Programming for Ordinary Mortals


by Bruce Sherwood

Abstract:
 
The Python module vpython makes it remarkably easy to write programs that generate navigable real-time 3D animations, as a side effect of computations. This is in contrast to most 3D graphics libraries, which require as a prerequisite very high computing skills. VPython programs can run in standard Python environments such as IDLE, Spyder, or a Jupyter notebook. They can also run in mobile devices, thanks to the use of the RapydScript-NG Python-to-JavaScript transpiler. Previous short presentations on VPython focused on its architecture and implementation. This presentation will instead be in the form of a tutorial on how to use VPython. No programming background other than basic Python is required. At glowscript.org click "Example programs" to see a variety of applications, which run in your browser. At vpython.org are instructions on installing the vpython module.
Bio:

Bruce Sherwood is an NCSU emeritus professor of physics and a Fellow of the American Physical Society, the American Association of Physics Teachers, and the American Association for the Advancement of Science. He is currently the main developer of VPython. He is co-author with Ruth Chabay of the introductory physics textbook "Matter & Interactions" for science and engineering college students (matterandinteractions.org). In North Carolina, this textbook is currently used at NCSU, High Point University, UNC-Greensboro, Wake Forest University, and Guilford College.
