Almost everyone is on lockdown or quarantine. That's why a lot of people spend their time on education and online courses right now.

Due to high demand, I have created a set of 6 #python webinars on typing, dependencies, business logic, and testing.

It all starts on 6 April and ends on 17 April. Three webinars a week: on Mondays, Wednesdays, and Fridays.

This course is targeted on juniors and middle engineers.

This time it is going to be in Russian 🇷🇺 Sorry, other folks! It is a good sign to start learning our beautiful language :)

​​Linux kernel manager and activity monitor written in #rust

kmon provides a text-based user interface for managing the Linux kernel modules and monitoring the kernel activities. By managing, it means loading, unloading, blacklisting and showing the information of a module. These updates in the kernel modules, logs about the hardware and other kernel messages can be tracked with the real-time activity monitor in kmon. Since the usage of different tools like dmesg and kmod are required for these tasks in Linux, kmon aims to gather them in a single terminal window and facilitate the usage as much as possible while keeping the functionality.

​​A #python tool that generates and runs test cases for Open API / Swagger based apps. Based on wonderful hypothesis project.

It reads the application schema and generates test cases which will ensure that your application is compliant with its schema.

The application under test could be written in any language, the only thing you need is a valid API schema in a supported format.

​​Prefect is a new workflow management system, designed for modern infrastructure and powered by the open-source Prefect Core workflow engine. Users organize Tasks into Flows, and Prefect takes care of the rest.

 prefect import task, Flow, Parameter


@task(log_stdout=True)
def say_hello(name):
    print("Hello, {}!".format(name))


with Flow("My First Flow") as flow:
    name = Parameter('name')
    say_hello(name)


flow.run(name='world') # "Hello, world!"
flow.run(name='Marvin') # "Hello, Marvin!"

​​macos-like TimeMachine but for Linux!

It uses rsync to incrementally back up your data to a different directory, hard disk or remote server via SSH. All operations are incremental, atomic and automatically resumable.

The goal of this project is to have a cross-operating system and minimal as possible backup noscript that can be easily reviewed by anyone without great effort. Additionally it should provide one task only and do it well without the need of external requirements and only rely on default installed tools.

​​Copy/paste detector for programming source code.

Copy/paste is a common technical debt on a lot of projects. The jscpd gives the ability to find duplicated blocks implemented on more than 150 programming languages and digital formats of documents. The jscpd tool implements Rabin-Karp algorithm for searching duplications.

> Between 1998 and 2003, searching for something on Google was magical.

> Today, if you're looking for something that is technical, specific, academic or generally non-commercial, good frigging luck. The world's best information retrieval system has devolved into something reminiscent of 2006-era Digg: A popularity index that's controlled by a small number of commercially motivated players. They call themselves "SEOs."

​​One of my own #python favourites: flake8 plugin to enforce best practices in writing pytest testcases.

It features useful checks that make tests consistent and correct by protecting users from popular mistakes.

Recently it found almost 20 serious problems in our own testcases in wemake-python-styleguide! 100% would recommend to anyone using pytest.

​​Introducing: storybook-addon-performance

An experimental storybookjs addon to help better understand and debug performance for #react components.

Features:
- Zero config (except for interactions): Generate performance information relating to server-side rendering and client-side mounting without any configuration
- Pin results: You can run some tasks, pin the result, make some changes, rerun the tasks and see what changed
- Interactions: Add your own custom user interactions to run as a parameter to your story. This lets you time how long interactions take. The API for this is super flexible and powerful!
- Control: Run all tasks for an overview, or run individual tasks to drill down on specific problems
- Marked: All tasks are marked with the User Timing API to allow for easy debugging of individual tasks in your browser's performance profiler
