This story is about improving your code quality and ways to reduce boilerplate when working with python. There are multiple options like using namedtuples, data classes, and Attrs. In this article, I will help you choose one!
Dunderless Python = Python -Dunder Methods
We All Love Python
Python is one of the programming languages I use the most. I started using it mostly for CTFs (for the fantastic pwntools framework) and ended up using it whenever possible.
We all love Python, but even Python got some pitfalls.
Double underscore should be pronounced “dunder”. So __init__ is “dunder init dunder”, or just “dunder init”. — Ned Batchelder
The main issues I see with Python are:
- When doing OOP, separating logic into multiple subclasses is very tedious as you need to make classes and define dunder methods for each of them. …
Not all of us want to do management or sales. Many talented and skilled people only want to do what they love most: It can be cloud administration, design, coding, or whatever. They don’t want to open a business and switch to a management role. Can they still become rich, not following the classical Silicon Valley role model?
I worked for a self-made billionaire: consulting for very influential CEOs, managers, and startup founders. I then switched to working with normal IT people: developers, cloud ops, etc. Usually, the successful ones opt for opening companies (or managing big ones) and follow the business classical roles: doing management and sales (which is not necessarily what they really like to do, they do it for the money).
Today, I am giving an alternative roadmap for those who want to succeed while keep doing what they are passionate about. …
Azure Function
Azure Functions is a serverless solution that allows you to write less code, maintain less infrastructure, and save on costs. Instead of worrying about deploying and maintaining servers, the cloud infrastructure provides all the up-to-date servers needed to keep your applications running.
Durable Function
Durable Functions is an extension of Azure Functions that lets you write stateful functions in a serverless compute environment. The extension lets you define stateful workflows by writing orchestrator functions and stateful entities by writing entity functions using the Azure Functions programming model. …
Every day, Linux users misuse the kill utility when trying to terminate a process. You go and type the famous kill -9, and all the problems are solved. But should you do that?
tl;dr Try to send a SIGTERM by using kill -15. After a few seconds, If It is not dead send a SIGINT (kill -2). Finally, If It persists send a SIGHUP (kill -1).
The kill Command
kill is a shell builtin in most Bourne-derived shells such as Bash and Zsh. Let’s man it.

When I was a kid, I spend most of my time playing with creative software. I made one game or two for some local competitions and built a website for a photographer (who was actually a friend of my big man and wanted to encourage me).
Here are the softwares I remember from that time. Some now have new epic versions. But I enjoyed the older version back at the time. Did you try any of these tools?

Not need to introduce It. I had a lot of fun using the lasso tool to create awesome fake images of my favorite animes and making horrible designs. I spent hours using it. I even made a giant map of my home city.
This article presents a roadmap for those who want to become Data Engineers in 2021. It also serves as a reference to learn and improve the understanding of the different skills required for this position.
For each skill category, I cite the skill points that are recommended with links to video/text courses and some reference books at the end. I have no association with the author, and this is not a referral article. The goal is to provide an easy way for you to navigate and improve your skills :)!
To become a skilled data engineer, you need to know computer science, dev, networking, and databases fundamentals.

Type hinting is an optional feature in Python that allows you to hint the type of the object(s) you’re using. As Python became the language of choice for many fields (e.g., scientific, data science, and data engineering), the need to improve the code quality and the coding workflow is becoming essential.
Challenges
As for all dynamic languages, there are few challenges to write robust and high-quality code. To cite the main ones:
- As there are no indications on Types of the objects that are passed around, programs usually end up with runtime issues. The developers gain time by writing typeless code but then lose it to write exhaustive tests to ensure that runtime issues are eliminated.
- The development experience is usually limited. The fact that types are unknown forces IDEs (like PyCharm) to infer them, which generally causes performance issues, gives inaccurate autocompletes / recommendations and limits the debugging features.
- As the…
Everyone around me continuously criticized Facebook et al. for ruining our family dinners, work meetings, and even weekend parties. Today, we praise them as the saviors of humanity in this pandemic age.
Covid-19 has pushed us into an anti-social life and work habits. Some argue that products like Facebook help us get over this crisis and make us experience their real value
As the use of these platforms increased during this period (Figure 1), We should seriously start thinking about their side-effects. They yield multiple flows that turn out to be dangerous to our societies. …
At some point or another in one’s career, you are going to work with people having difficult personalities. From research and personal experience, We know that many managers and business leaders suffer from some level of narcissism.
This article is about developing the right strategy to manage those kinds of people. The strategy you opt for can become a key to your success or failure at one stage of your career, so. you have to craft it carefully.
