I Built 11 Free Web Tools for Developers and Creators โ€” Here's How

Hi everyone! ๐Ÿ‘‹ I'm Maruf, a web developer from Meherpur, Bangladesh. Over the past year, I've been building a personal project called MARUF-X-HUB โ€” a collection of 11+ free web tools that anyone can use without signup, ads, or payment. I wanted to share my journey, the tech stack, and the tools I built in case it helps other developers. ๐Ÿ”— Live site: web.maruf-x-hub.page.gd ๐ŸŽฏ Why I Built This Most free web tools today have: โŒ Require signup โŒ Have u...

Dojo Feed Case Study: How Organic Viral Engagement Validates Gamified Community Platforms

Community platforms face a critical challenge at launch: achieving sustainable engagement without artificial inflation. Dojo Feed , a HYNAWEB product, launched on September 17, 2026. Within 72 hours, organic user-generated content created a viral engagement pattern that validates the platform's gamification architecture. This is a data-driven analysis of how unexpected user behavior proves product-market fit. ๐Ÿ“Š The Engagement Metrics (72 Hours Post-Launch) Platform: D...

7 Checks to Make Before Sending Gerber Files to PCB Manufacturing

Exporting a PCB design is not the same as verifying the manufacturing package. Your board may look correct in the original design application, but the fabricator normally works from exported Gerber, drill and supporting files. A missing outline, displaced drill file or incorrect layer can therefore survive unnoticed until somebody inspects the actual deliverable. The safest habit is simple: Review the files you are going to send, not only the design from which they were generated. ...

Building FoxyInvoice โ€” Chapter 4: Multi-tenancy & data security โ€” the vault

This series is written in the open, from a real production system. This chapter is the vault: identity, isolation, authorization, and the tests that prove it holds. [All chapters and diagrams live in the public repo.] Multi-tenant means many unrelated companies share one running system and one database, each seeing only its own data. Get it right and hosting stays cheap forever. Get it wrong and Business A reads Business B's invoices โ€” for a billing product, that's the ballgame. This chap...

lets explore data Structures in Python

Introduction Data science begins with data, and how that data is stored determines how easily it can be cleaned, explored, and analyzed. Python is a data science tool tat anyone who is interested in data science would be wise to utilize. Python's four core data structures (lists, tuples, dictionaries, and sets) form the foundation for this work. Lists hold ordered collections such as a column of measurements or a series of records. Tuples protect values that should not change, such as fi...

I Tried to Build a Bengali Voice Dialer for Android. Here Is What Actually Happened and How I Finally got it right.

DockFlare: Docker labels, Cloudflare Tunnels, and a little less dashboard clicking

Hello everyone, I wanted to share a project I started in 2025 to solve something that kept getting on my nerves in my own homelab. Every time I deployed another container, I found myself back in the Cloudflare dashboard. Add a hostname, point it at the service, configure Access, and remember to clean things up when I stopped using it. Nothing particularly difficult. Just the same work, again and again. Everything else about the service was already in my Docker Compose file. Having it...

I got tired of rebuilding the same Angular mobile app setup, so I built LaunchKit Mobile

Every time I started a new Angular mobile app, I found myself rebuilding the same foundation: Authentication Refresh tokens Secure storage Offline handling Push notifications Biometrics Translations RTL support Dark mode API integration Eventually, I decided to turn that repeated setup into a reusable starter. That became LaunchKit Mobile , an Angular 22 + Ionic + Capacitor starter designed to provide the production plumbing before you start building the actual bu...

Your Agent's Memory Is an Attack Surface

In Post 3, the behavioral difference tracked the memory graph, not the substrate. When I swapped one individual's learned associations into an identical brain, the subject did not just get confused. It went below chance, scoring 0.17 on the six-cue, three-action task, actively steered toward another individual's answers. In an isolated sandbox that is a curiosity. In any real system where an agent's behavior is reinstated from an external, writable memory, it is a vulnerability. The structural i...

Exact Match Or Fuzzy Logic For OFAC? 1,400 Tests Changed My Mind.

api, #security, #compliance, #discuss Last Tuesday I typed Sergei Ivanov into a sanctions screener and watched it explode. The API came back with 101 total matches : 50 from OFAC SDN, 1 from the UN Consolidated list, 50 from EU FSF, and zero from UK FCDO or BIS CSL. Threshold was 0.7. One common Russian name. A hundred and one alerts. I'd spent the previous week arguing that fuzzy logic was the only responsible way to catch sanctions evaders. They change spellings, swap transliteration...

How I Built a Zero-Cost Python Webhook Engine to Bypass a High-Friction Voting System

When I entered the CANEX Create-Thon competition, I quickly realized I wasn't just competing against other creators but rather I was also competing against bad UX. The Gebeya platform requires users to complete a full email sign-in just to cast their vote. For organic traffic, that level of friction means a 90% drop-off rate. Instead of begging for votes, I decided to engineer a bypassing channel. I've detailed below how I built the zero-cost automated funnel using a code-first architectu...

Ask HN: What is one plausible path to 'AI extinction'?

This is being thrown around a lot, including the dreaded "10% chance by the end of this decade". Every conversation I have seen about this, mostly on twitter, not once have I seen anyone connecting the dots on concretely and plausibly how this might pan out. It is usually 1. Train powerful AI 2. ??? 3. Extinction I personally find it implausible, but some quite smart people have talked about it so I am also not dismissing it as pure fear-mongering. The reasons I do not think it is plausible: 1...
