MerMark Editor v0.2.0 - Markdown/Mermaid editor with built-in Claude/Codex

Hey, me again. Posted MerMark Editor here a while back — first post got 120+ GitHub stars and the binaries crossed 7 000 downloads, so thanks to everyone who tried it. Just shipped v0.2.0 and the diff is big enough that I think it's worth a fresh post. Pre-emptive disclaimer (so I don't have to argue in the comments) Yes, I know Obsidian exists. Yes, Obsidian has AI plugins. No, I'm not...

Exploiting vsftpd 2.3.4 on Metasploitable2 (Step-by-Step Guide for Beginners)

One of the biggest turning points in learning cybersecurity is understanding how attackers move from: Discovery → Exploitation → Access In a training session I led, students went from running a simple scan to gaining root access on a vulnerable machine. The excitement was great — but the real value was understanding how and why it worked. In this guide, you'll replicate that exact process ste...

I built a multilingual AI tools directory in Kotlin and Next.js, solo. Here's what 6 months taught me (mostly painful).

Posting this from Nouméa (New Caledonia), currently here for work. Big timezone gap with most of you, so apologies if I'm a few hours behind on replies. Happy to answer any questions about the stack, the SEO disaster, the bot detection, or anything else 🌊 I'll be honest, I almost didn't write this post. There's a glut of "I built X in Y months" articles on DEV right now and most of them follow ...

Check your auth log: grep "Failed password" /var/log/auth.log | tail -20 You'll see hundreds — sometimes thousands — of failed login attempts from IPs you've never seen. Botnets scan the entire IPv4 space and hammer p...

how do i install revit and two other autodesk programs on my computer?

I have 3 Autodesk programs, all of which I downloaded in a dubious way (I'm saying this so I don't get caught by the Reddit bot). All 3 work individually, but when I try to use all 3 at once on my computer, they fail. https://preview.redd.it/ax3nw933mezg1.png?width=770&format=png&auto=webp&s=b89786896ebec02b92368cfa689d59dc9a64f815 https://preview.redd.it/0upmcblnkezg1.png?width=778&am...

Your FAQ is useless to AI. Here's how to fix it.

Your FAQ is useless to AI. Here's how to fix it. Your FAQ page probably won't show up in ChatGPT. And if it does, Claude won't cite it the same way Google would. That's because AI engines don't read FAQs like humans do. They're looking for something much more specific—and most brands are getting it wrong. The difference comes down to how you structure the page. Google Search has spent ...

5 things healthcare engineering teams get wrong about HIPAA CI/CD

I've spent the last six years building cloud infrastructure and CI/CD pipelines for healthcare and defense engineering teams. The same five mistakes keep showing up across every HIPAA engagement I take on, and none of them are about not knowing what HIPAA requires. Engineers in healthcare aren't dumb. They've read 45 CFR § 164. They know what audit logs are. They've sat through compliance trainin...

Generalization of Sum-Types, Pattern Matching & Niche Optimization

Looking at system's languages like Zig & Rust and thinking about how I want to implement sum types for my own statically typed, no GC, AOT compiled language I'm faced with the question of whether there's a nice way to generalize niche optimization. Sum Types and the default way they're represented under the hood (tag + union) is fine for most cases but there are many cases where you ideally wa...

OpenTelemetry signals from first principles

There's a lot of high-noise, low-value content around OpenTelemetry out there, so I've tried to put together the simplest description I could by incrementally building up from needs that arise in your systems. I hope it might help cut through some of the less obvious concepts like context propagation and exponential histograms. The format is very loosely pinched from "The Little .." seri...

I built a production-ready RAG backend (because most examples break in real life)

Most RAG (Retrieval-Augmented Generation) projects you see online are great demos. But try running them in production and you’ll quickly hit issues: no ingestion pipeline no async processing no scaling story no observability no proper deployment setup So I decided to build something that actually works beyond demos. Introducing Ragify An open-source, production-oriented RAG backend built wi...
