Brian #1: Online CookieCutter Generator
- “Get a ZIP-archive with project by filling out the form.”
- By @kpavlovsky_pro Konstantin Pavlovsky
Michael #2: cutelog – GUI for Python's logging module
- This is a graphical log viewer for Python's standard logging module.
- Features
- Allows any number of simultaneous connections
- Fully customizable look of log levels and columns
- Filtering based on level and name of the logger, as well as filtering by searching
- Search through all records or only through filtered ones
- View exception tracebacks or messages in a separate window
- Dark theme (with its own set of colors for levels)
- Pop tabs out of the window, merge records of multiple tabs into one
- Based on PyQt5 speaking of GUIs
Brian #3: wagtail 2.0
- “Wagtail is a content management system built on Django. It’s focused on user experience, and offers precise control for designers and developers.”
- The Zen of Wagtail - nice philosophy of the project page to let you know if this kind of thing is right for you and your project.
- In 2.0
- a new text editor
- Django 2 support
- better scheduled publishing
- …
- wagtail docs
- gallery of sites made with wagtail
Michael #4: peewee 3.0 is out
- Peewee is a simple and small ORM. It has few (but expressive) concepts, making it easy to learn and intuitive to use.
- A small, expressive ORM
- Written in python with support for versions 2.7+ and 3.4+ (developed with 3.6)
- Built-in support for SQLite, MySQL and Postgresql.
- Numerous extensions available (postgres hstore/json/arrays, sqlite full-text-search, schema migrations, and much more).
- Although this was pretty much a complete rewrite of the 2.x codebase, I have tried to maintain backwards-compatibility for the public APIs.
- Exciting because of its async support via peewee-async
database.set_allow_sync(False)
async def handler():
await objects.create(TestModel, text="Not bad. Watch this, I'm async!")
all_objects = await objects.execute(TestModel.select())
for obj in all_objects:
print(obj.text)
Brian #5: Machine Learning Basics
- “Plain python implementations of basic machine learning algorithms”
- From the repo:
- A repository of implementations of basic machine learning algorithms in plain Python (Python Version 3.6+). All algorithms are implemented from scratch without using additional machine learning libraries. The intention of these notebooks is to provide a basic understanding of the algorithms and their underlying structure, not to provide the most efficient implementations.
- Linear Regression
- Logistic Regression
- Perceptron
- k-nearest-neighbor
- k-Means clustering
- Simple neural network with one hidden layer
- Multinomial Logistic Regression

Michael #6: Cerberus
- Cerberus provides powerful yet simple and lightweight data validation functionality out of the box
- designed to be easily extensible, allowing for custom validation
- Origin of the name: CERBERUS, n. The watch-dog of Hades, whose duty it was to guard the entrance;
schema = {'name': {'type': 'string'}, 'age': {'type': 'integer', 'min': 10}}
v = Validator(schema)
<span class="n">document</span> <span class="o">=</span> <span class="p">{</span><span class="s1">'name'</span><span class="p">:</span> <span class="s1">'Little Joe'</span><span class="p">,</span> <span class="s1">'age'</span><span class="p">:</span> <span class="mi">5</span><span class="p">}</span>
<span class="n">v</span><span class="o">.</span><span class="n">validate</span><span class="p">(</span><span class="n">document</span><span class="p">)</span> <span class="c1"># False</span>
v.errors # {'age': ['min value is 10']}
