After giving it a lot of thought, I decided to use Python. GIL thread concurrency is sufficient. Mining might suffer, but can be replaced with a C mining module. Most importantly, code will be easier to read for open source contributors and will be heavily unit tested. Using frozen pip dependencies, virtualenv, and vagrant or docker, we can fire this up fairly easily under any operating system.   Creating a Jupyter notebook widget This post will provide a step-by-step tutorial for creating and running a Jupyter widget.   Let’s Build the Tiniest Blockchain In Less Than 50 Lines of Python.   Python3 asyncio - call async code from synchronous code Projects yams - 57 Stars, 6 Fork A collection of Ansible roles for automating infosec builds. dependency - 16 Stars, 0 Fork A dependency injection framework for Python. ptime - 15 Stars, 1 Fork IPython magic for parallel profiling. sammy - 12 Stars, 1 Fork Python library for generating AWS SAM (Serverless Application Model) templates with validation. cpython_core_tutorial - 9 Stars, 0 Fork Tutorial to contribute to the CPython project bod - 3 Stars, 0 Fork objdump beautifier yacron: - 0 Stars, 0 Fork A modern Cron replacement that is Docker-friendly. Creating your first Python program I want to highlight that we recently create tutorials on Python that took 160+ hours to create with beautifully annotated screenshot, and is very comprehensive. The tutorials are created by a Google veteran and I have personally edited them. The course covers Python Basics like Introduction, Environment setup and Install Guide. It also introduces Main Function, Variables, Strings, Tuple, Conditional Statements, OOP Concepts, and Loop. We also touch on advanced topics like Regex Tutorial, OS Module, Shell Script Commands, and XML Parser. Here is the Link: http://www. guru99. com/creating-your-first-python-program. html

In this post, we will start from scratch, covering some basic fundamental techniques and implementations in Python. In the future posts, we will cover more sophisticated methods such as content-based filtering and collaborative based filtering.   Python Gem #19: Look up table > if chain What should be a really simple function has turned into a fifty-line gargantuan that’s too hard to read properly because of the sheer number of lines. The culprit; a seriously long if-elsif-else chain. But not to fear; there’s a better way!  My favorite terrible Python error message TypeError: object() takes no parameters  A TDD approach or building microprocessor model in Python Modern microprocessors are a very complex piece of machinery with a lot of different parts. I've learned assembler and microprocessors in my undergraduate course some years ago but, as I've been working on higher level software languages for quite some time now, I forgot many things. Lately I decided to revisit some of the topics on microprocessors and to build a very simple model of a microprocessor in Python for education purposes (I work as CS professor). You can find the final source code and some samples at https://github. com/joaoventura/simproc.   4 interactive Sankey diagrams made in Python – plotly – Medium Plotly has a new member of the Plotly. js chart family: The Sankey diagram.

The primary goal: supplement the dataset’s human readable location data with geographic coordinates.   CPython internals: Arbitrary-precision integer implementation Have you ever noticed that Python supports integers of any size? Here is a quick glance at it.   How Did We Build Book Recommender Systems in An Hour Part 2 — k Nearest Neighbors and Matrix… In the last post, we saw how we could use simple correlational techniques to create a measure of similarity between the books’ users based on their rating records. In this post, we will explain how you can use those same sort of similarity metrics to recommend books to a book’s readers.   Posting messages to Slack using incoming webhooks and Python3 Requests API I wanted to make a short post on using Slack’s incoming webhooks feature to post messages to Slack using the human-friendly Requests API in Python3.   Find Top Developers We help companies like Airbnb, Pfizer, and Artsy find great developers.

In this tutorial, we’ll use Python to learn the basics of acquiring geospatial data, handling it, and visualizing it.  More specifically, we’ll do some interactive visualizations of the United States!  Automating Web Analytics through Python The current blog deals with the case how to implement web analytics in Python. I am enthusiastic about the options that are available inside Google Analytics. Google Analytics has a rich variety of metrics and dimensions available. It has a good visualization and an intuitive Graphic User Interface (GUI). However, in certain situations it makes sense to automate webanalytics and add advanced statistics and visualizations. In the current blog, I will show how to do that using Python.   TransitFlow — using Python and Processing to visualize regional transit frequency Transit networks with higher frequency and shorter waiting times will yield a more reliable and empowering experience for passengers than those with lower frequency and longer waiting times.   Remote-controlling macOS with a Python Telegram bot I needed a quick way to remotely perform system operations: adjusting & muting the system volume, screen brightness, and putting the display to sleep.
