Intro
I customized my tmux and made it onto Hacker News front page 😎
Last month I had another feature on HN front page with my post about customizing tmux 🖥️. In addition to that, I have also explored creating a configuration file management tool with Claude AI 🤖, and writing an AWS Lambda function in Go ƛ.
In this month's newsletter, you will get to check out the statistics behind the reality of unsustainable AI usage in production 📉, ask yourself a question whether we should design for unstable Internet connections 🔌, and explore a CLI todo application that I now use instead of Apple Reminders 🍎
Hope you find the content interesting and get to learn something new 🙌

Customizing tmux and making it less dreadful | Evgenii Pendragon
I have been exploring some new tools here and there. When I started watching Primeagen, I took a note of several tools that he was using and advocating for. One of them was tmux. This tool is a terminal multiplexer. What that means is you can have many terminals in one. In this article, I attempt at configuring and customizing it to fit my needs and making it more usable.
P.S. This post got featured on the front page of HackerNews 😎. Here is a link to that post: HN Post Link
Using AI to create local configuration management tool | Evgenii Pendragon
Recently, while working on my tmux customization project, I have made quite a few changes to the .tmux.conf file. In addition to that I have been making updates to my .zshrc and config.conf (Neofetch) files. I was trying out tmux on my other machine and I wanted to use the same setup there. That made me think up an idea of setting up one GitHub repository that would host all of my essential configuration files for different software that I use locally on my machines. In this article, I detail how I made that happen.
Converting images to ASCII art with Go in AWS Lambda | Evgenii Pendragon
In an attempt to use Go in the context of AWS, I wanted to see how Go would work with AWS Lambda. I decided to create a small project where the function would take an image and convert it to an ASCII art. Details on how that went are in this article.
If you are interested to check out the full repository for this project, you can find it in here

Why I'm Betting Against AI Agents in 2025 (Despite Building Them)
A wonderful foray into the world of data science behind the AI agent work and why the current hype around autonomous agents is mathematically impossible.
As author states,
- Error rates compound exponentially in multi-step workflows. 95% reliability per step = 36% success over 20 steps. Production needs 99.9%+.
- Context windows create quadratic token costs. Long conversations become prohibitively expensive at scale.
- The real challenge isn't AI capabilities, it's designing tools and feedback systems that agents can actually use effectively.
Coding with LLMs in the summer of 2025 (an update) - <antirez>
A great insight into the state of vibe coding as of summer of 2025 with valuable advice like be able to come up with MVP faster and test your ideas with smaller time and money costs, using different LLMs for different tasks, and using LLMs as a tool to help you as a developer - not substitute your work.
Should we design for iffy internet?
Around 97% of US households have internet access, but bandwidth and latency are likely worse than you expect. The author is asking a question that I often encounter in my line of work: "Should we design applications to accommodate poor connectivity?" Often times the answer is yes, because the businesses want to capture as many users as they can. But what is the ROI that comes from these efforts?
As my manager likes to say that he hates to say it: "Is the juice worth the squeeze?" 🍋
Resources
chezmoi - Manage your dotfiles across multiple diverse machines, securely.
One of the commenters under the HN Post told me about this other existing tool for the local dotfile management called chezmoi. It is indeed a more fully featured tool that can help users sync up their config file changes.
Taskwarrior
Taskwarrior is Free and Open Source Software that manages your TODO list from the command line 📄. I have been using it for the last month and have been very impressed with it. I used to use Apple Reminders for the most part, but recently have transitioned my work todo lists all the way to Taskwarrior.
PocketBase - Open Source backend in 1 file
I found PocketBase randomly while watching YouTube Shorts. PocketBase exists to assist building self-contained applications that can run on a single server without requiring to install anything in addition. The basic idea is that the common functionality like crud, auth, files upload, auto TLS, etc. are handled out of the box, allowing you to focus on the UI and your actual app business requirements.
While I am yet to try this tool out, I do think that this tool will take off and become more widely adopted as the time goes on. It is also written in Go ❤️
