How to adapt to the new Instagram algorithm?

Yes, I just screenshotted the Notes app to get the cover.

Instagram growth is progressively turning into a more complex topic, as Instagram’s algorithm becomes more and more strict and limiting when it comes to organic reach, which isn’t being well received by creators and business accounts.

From mid-2019 to 2020, there have been several changes in the algorithm: For example, Instagram learns to detect all open source automation bots (for those bots that Instagram can not detect — it just shut down their public repositories, R.I.P. and Instagram-PHP). …

Imagine that you need to create an automatic report in CSV format. Imagine that you are a backend developer that doesn’t have frontend skills but still you want to code the report autogeneration.

I’ve launched a lot of indie projects and I always struggle with several things. One of them was DevOps: I am a perfectionist with a good sense of shitcode and crutches. I used to have a lot of bash scripts that helped me with deploying all my stuff — I hate this approach because It looks very manual for me. I wanted to automate everything. And I was incredibly happy when I discovered Heroku — it outsourced all DevOps tasks including auto-deploy-after-you-pushed-code-to-GitHub-master-branch. It was amazing.

When the projects became popular and the size of the free tier appeared to be…

How to transfer a Telegram bot in 2020.


I have the bot that we’ve been developing with my friend last year. Since I decided to continue its development by myself with further paid acquisition and (I hope) monetization, I really want to have full control of the bot in BotFather. So I decided to look for a solution: How can I transfer the bot ownership to my account?


There is no official Telegram service that can change the Telegram bot owner right now, but according to the official Bot Support (see screenshot) this feature might be implemented in the future.

I’ve spent a huge amount of time compiling all articles about Django Admin actions creation. Most of them were from 2010–2012 which made me really sad. Finally, I figured out everything I need and not I want to share “the right answers”. Enjoy.

And this is the coolest thing — not all people like to code even if they can, they like to push buttons without opening the shell. Django…

In this story, I’ll tell you how I figured out how to deploy serverless python telegram bot on ( This tutorial will be also helpful if you write on Javascript or other programming languages.


I don’t like the examples from python-telegram-bot GitHub, I just think they are not scalable. I really wanted to separate “frontend” (Telegram bot interface) and “backend” (all logic, database handling, background tasks). In that case, you can develop these two parts separately, host them on different servers… or serverless?

Some of my friends use Heroku to host their bot’s frontend and that is great solution…
