I was tired of studying security tools from static cheatsheets, so I built ShellStack

I was tired of studying security tools from static cheatsheets, so I built ShellStack When I started prepping for CEH and doing more CTFs, I ran into the same wall over and over: every resource for learning offensive security tools was either a wall of text in a PDF, a GitHub gist with no context, or a cheatsheet that assumed you already knew what half the flags did. I didn't want notes. I wanted something that felt like sitting at an actual terminal — where I could browse tools, see real commands with context, and build the exact command I needed without digging through five tabs. So I built ShellStack . 🔗 Live: https://shell-stack.vercel.app/ 💻 Code: https://github.com/shlokkokk/ShellStack What it actually does ShellStack is a cybersecurity study platform built around one idea: learning security tools should feel operational, not passive. 280+ curated offensive security tools , organized into 19 categories, each with deep-dive docs — commands, common flags, when to use it, installation notes, and real examples Interactive command builders — instead of memorizing flag combos, you fill in a form and get a ready-to-copy command generated live 20 CEH-aligned learning modules , built for structured study instead of flipping through slides 1,000+ command cheat sheet with fast search and one-click copy A terminal-inspired UI that actually feels like a cyber-ops console instead of another docs site The build Stack: React 19, TypeScript, Vite, Tailwind CSS, GSAP, React Router, Radix UI primitives A few things I focused on: Search that actually ranks results. Early on, tool search was just naive string matching, which meant typing "nmap" could bury the actual Nmap entry under ten unrelated tools that happened to mention it in a description. I rebuilt it to weight exact and prefix matches higher, so the tool you're looking for shows up first, not buried on page 3. Command builders that don't feel like a form. The tricky part wasn't the UI, it was designing a data model that

How a Bookstore in Finland Reaches the Whole World

Week 0 of my DevOps Micro Internship was about the foundations—the parts of the internet you use every day without thinking about them. The exercise that made it click was a simple scenario: a friend launches an online bookstore called EpicReads, hosted on a server in Finland, and asks how people anywhere in the world can open it. The answer is a short chain of technologies working together. The Chain of Technologies Packet Switching: When someone opens the site, their request does not travel as one big lump. Packet switching breaks the data into small packets that each take the best available path across the network and get reassembled at the other end. This is what keeps the internet fast and resilient even across continents. IP Addresses & TCP/IP: Every device on the way has a unique IP address, like a postal address, so the user's computer and the Finland server can actually find each other. The TCP/IP suite runs the conversation: IP handles addressing and routing, while TCP makes sure the packets arrive complete and in the right order, asking again for anything that went missing. HTTP & HTTPS: On top of that sits HTTP and HTTPS, which define how the browser and server actually exchange the web pages. HTTPS adds encryption, so a customer's details and payment stay private. DNS: The last piece is DNS. Nobody wants to type an IP address, so DNS acts as the internet's phonebook, translating epicreads.com into the server's IP. To point a domain at an IPv4 address, you use an A record . The Biggest Takeaway The biggest lesson for me was not any single term. It was seeing how these layers hand off to each other so cleanly that the whole thing feels instant to a user. Understanding that chain is the groundwork for everything else in DevOps, because once you know how a request really travels, troubleshooting stops being guesswork. P.S. This post is part of the DevOps Micro Internship with Agentic AI Cohort 3 by Pravin Mishra. You can begin your DevOps journey by joining

Kenapa Banyak Frontend Developer Memakai Next.js untuk Pekerjaan, tapi Vue.js untuk Personal Project?

Artikel ini juga tersedia dalam bahasa Inggris Pendahuluan Beberapa waktu terakhir saya sering berdiskusi dengan beberapa frontend developer mengenai framework yang mereka gunakan. Pertanyaan saya sebenarnya sederhana. "Kalau membuat frontend web, biasanya pakai framework apa?" Hampir semuanya memberikan jawaban yang kurang lebih sama. "Tergantung kebutuhan." Dan saya setuju. Tidak ada framework yang selalu menjadi pilihan terbaik untuk semua kondisi. Namun, setelah pembahasannya berlanjut, mereka mulai menceritakan pengalaman dan preferensinya masing-masing. Nah... Di sinilah saya mulai menemukan pola yang menarik. Dari beberapa developer yang saya ajak berdiskusi, cukup banyak yang mengatakan bahwa mereka lebih sering menggunakan Next.js / React untuk pekerjaan, sedangkan Vue.js lebih sering digunakan untuk personal project. Padahal saya tidak pernah bertanya, "Kalau kerja pakai apa?" atau "Kalau project pribadi pakai apa?" Penjelasan itu muncul begitu saja ketika mereka mulai menjelaskan alasan di balik framework yang mereka pilih. Awalnya saya mengira itu hanya kebetulan. Tapi setelah mendengar pola yang sama dari beberapa orang... Saya jadi penasaran. Kenapa banyak developer yang sudah menguasai keduanya justru memilih memisahkan penggunaannya? (・_・;) Disclaimer Tulisan ini bukan hasil survei atau penelitian resmi. Ini hanyalah pola yang saya temui dari beberapa frontend developer yang sempat saya ajak berdiskusi. Pembahasan Vue.js Kalau melihat ekosistem frontend saat ini, Vue.js jelas bukan framework yang kecil. Komunitasnya besar. Dokumentasinya bagus. Ekosistemnya juga sudah cukup matang. Namun memang harus diakui, jika dibandingkan dengan React dan Next.js, komunitasnya memang masih lebih kecil. Lalu muncul pertanyaan. Kalau begitu... Kenapa masih banyak yang memilih Vue.js untuk personal project? Dari beberapa jawaban yang saya dengar, ternyata alasan utamanya bukan karena performa. Bukan juga karena framework lain kurang bagus. Melainkan karena pengalama

I Audited My Own Subscription App. The Paywall Wasn't the First Finding

A subscription audit should survive contact with a real app. So I started with mine. TurnTalk is a live iOS travel translator with in-app purchases. I operate the app and its RevenueCat implementation. That makes it a useful public example, but not a customer case study. I will not claim a conversion lift I have not measured. Here is the first finding I would put at the top of its audit. Evidence: the store page introduces several different jobs The subtitle makes a focused promise: Understand Any Guide, Live But the first screenshot sequence spreads attention across: AI travel translation Voice translation Photo translation Instant translation Each feature may be useful. The issue is not feature quality. The issue is that a visitor has to decide which product TurnTalk is before deciding whether to download it. A traveler who wants to understand a live tour guide is evaluating a specific job. A visitor comparing general translator apps is evaluating a much broader category. Those users arrive with different intent. Why I would rank this before a paywall redesign The paywall cannot repair ambiguous acquisition intent. If the store page attracts people for four different jobs, aggregate trial and purchase rates become difficult to interpret. A low conversion rate could mean: The paywall is weak The first session does not prove the promised value The visitor downloaded for photo translation but reached a live-translation flow The listing attracted broad curiosity instead of durable travel intent Changing the paywall first would alter one screen while leaving those explanations mixed together. That is not a clean experiment. P0 action: make the first three screenshots tell one story I would test a narrower opening sequence: Situation: You joined a tour, but cannot understand the guide Mechanism: Put in your existing earphones and start live translation Outcome: Hear the guide in your language without staring at the screen Photo translation and secondary conversation mod

React development and clean architecture

Hot take 👀 The hardest part of React isn't hooks. It's knowing how to structure an app so it stays maintainable as it grows. Clean architecture beats clever code every time. What's been the biggest challenge in your React projects?

Fine, electric mountain bikes don’t suck

Cheater, I'd grumble between huffs as yet another e-bike rider casually skittered past me on a steep ascent. It's this purist attitude that, for years, has left me blind to one simple fact: electric mountain bikes are fun! My attitude adjustment came a few weeks ago, the very first time I rode an Amflow PX […]

I tried to trick my own AI-skill signing tool. Here's what happened.

Over the last few months I’ve noticed a pattern emerging across AI tools. Whether it’s Claude Skills, Cursor, Codex, or custom agent frameworks, we’re increasingly giving AI agents “skills”—packages containing instructions, documentation, and sometimes scripts. The problem is… A skill is usually just a Markdown file (plus some assets). Nothing tells you: Who created it. Whether it has been modified. Whether the version your AI is executing is the same one you reviewed yesterday. Whether someone quietly injected new instructions into it. As AI agents become capable of executing increasingly powerful workflows, that becomes a real supply-chain problem. So I built Skillerr. ⸻ What is Skillerr? Skillerr is an open-source protocol and CLI that adds trust and verification to AI skills before they’re executed. Instead of treating a skill as “just another folder,” Skillerr treats it as a verifiable package. It focuses on three things. Package Integrity Every packaged skill receives a unique content-derived identifier along with cryptographic SHA-256 hashes. If any file changes after packaging—even a single character—Skillerr detects it immediately. No silent modifications. ⸻ Structured Contracts Instead of relying on long paragraphs that an AI has to interpret, a Skill contains a structured contract describing: required inputs permissions forbidden actions expected outputs whether a human has actually reviewed it This makes skills easier for both humans and AI agents to reason about. ⸻ Optional Public Provenance Authors can cryptographically sign their skills. Optionally, the package digest can also be anchored into Sigstore’s transparency log, making it independently verifiable without trusting Skillerr itself. Importantly: Only cryptographic identifiers are published. No prompts. No documentation. No knowledge base. No proprietary content. ⸻ I tried to break my own tool Before releasing it, I intentionally attacked it. First I packaged and signed a simple CSV processing s
