TL;DR I built a workflow engine inside bunqueue with first-class saga compensation, retries with exponential backoff, branching, parallel steps, loops, sub-workflows, and human-in-the-loop signals. It runs on Bun + SQLit
We shipped a Next.js blog platform last year. Schemas were in place, the Rich Results Test was passing, and everything looked correct. Then we opened Google Search Console three weeks later and found that our BreadcrumbL
When you first hear about integrating Jira with CI/CD, it often sounds abstract—like something happening “around” your application rather than inside it. But once you start building a real system, you quickly realize the
https://www.kasetto.dev https://github.com/pivoshenko/kasetto Hey DEV community! 👋 I want to share an open-source tool I built for myself, and that I hope will be useful to other developers working with AI agents. The P
I Thought My Index Would Fix Everything I added the index. Ran the query. And… nothing changed. Same slow response. Same frustration. That was the moment I realized something uncomfortable: PostgreSQL doesn’t care about
Your website could be losing hundreds of visitors every day, and you might not even know it. Technical issues, missing tags, and slow load times quietly drag your rankings down while your competitors move up. That is exa
Every fraud tool on the market — IPQS, Sift, DataDome — was built for a world where bots used datacenter IPs. That world is gone. Today, fraudsters use antidetect browsers like Kameleo, GoLogin, AdsPower, and Dolphin to
I built an end-to-end NLP project that detects mood from text and turns it into a usable application. Key features: Multi-class mood classification Confidence score + probability distribution Recommendation system FastAP
I started studying prompt injection in February. I was building Parapet , an open-source LLM firewall, and I needed to understand what I was defending against. So I wrote a simple test. Five lines of XML in a normal chat
Reformatting text between naming conventions is one of those tedious tasks that eats up time without adding value. Paste, convert, done. The Case Converter at Ultimate Tools converts text between 8 common case formats in
A week ago I saw that there was a new version of Neovim(v0.12.0) out and I decide to upgrade to it. These are the challenges that I faced and how I solved it. Context, as is required nowadays. I use LazyVim to transform

YouTube thumbnails are publicly accessible images — but YouTube gives you no obvious way to download them. You have to dig into page source or construct the URL manually. There's a faster way. The YouTube Thumbnail Downl
There is a design decision at the heart of in-concert that surprises people when they first encounter it: the engine knows nothing about your data . No domain objects stored inside the engine. No variable interpolation i
Despite all the recent breakthroughs in AI and tooling, software development hasn’t fundamentally changed. In my journey as an engineer, I’ve observed four patterns that track with experience levels. Let me explain: Ther
Like most users of AI agents like Claude Code, I have been frustrated by the agent memory problem. The models have gotten extremely good and no longer lose focus in one long conversation like they used to, but across ses

Building a simple chatbot is easy. Building a production-ready autonomous agent that can manage its own memory, use external tools, and collaborate with other agents is hard . In 2026, the "DIY" approach to agent archite
You have an idea. Maybe you are still building it. Maybe it is ready, but you want to build an audience before you launch. Either way, the worst thing you can do is wait until launch day to start collecting emails. A wai

Overview It's 2 AM. GuardDuty just flagged a malware finding on one of your EC2 instances. What happens next determines whether you have a contained incident or a full-blown breach. If the answer is "someone gets paged a
We've all seen it. You open a pull request from a teammate — or your past self — and the description says: "fix bug" That's it. No context. No what changed. No why. You're now a code archaeologist trying to reverse-engin
If you maintain real services, "we have Dependabot" is not the whole story. You still end up bouncing between PR noise, registries, advisories, and spreadsheets when you want a single place to answer: what is exposed rig
Humans are notoriously terrible at intuitive probability. Imagine you wake up feeling slightly off. You visit the doctor, and she runs a battery of tests. A week later, she calls with bad news: you tested positive for a
We’ve all been there: you type a complex command, hit enter, and get a face-full of command not found or a cryptic shell error. Usually, you’d reach for the legendary thefuck to fix it. But this weekend, I decided to tak

In 2024, I watched as a single faulty cloud update led to a wave of global disruptions. Critical services stopped working. Companies and even governments had hours of downtime. I felt the panic. I saw how devastating a l
After writing about optimising my old Ryzen 7 3700U laptop, I wanted to go deeper into one specific tool: VS Code. It’s my main editor, but on older hardware it can feel slow, especially during startup or when switching

We all do it. Copy a chunk of code, paste it into ChatGPT, ask "why doesn't this work?" — and accidentally send your AWS keys, database credentials, or a client's email along with it. I did it once. I pasted a config fil

This is a submission for the DEV April Fools Challenge What I Built I built an Emotionally Manipulative Calculator — a calculator that doesn’t just calculate… it remembers, judges, and occasionally refuses to cooperate.
Every non-English programming language I've seen does the same thing: translate the keywords. if , while , return become local words, but the grammar stays identical to C or Python. That never felt right to me for Korean
