You already have Java endpoints, input validation, and HTML templates. Now you want inline editing and live search without maintaining a separate application in the browser. HTMX lets an HTML element send an HTTP request and replace a selected part of the page with the returned…
Your app is live. You tested signup, you tested the main feature, everything worked. Then a week later someone replies to your launch post: "Is your site broken? I can't log in." Too often, that is how founders find out their app is broken: from a user, days late, after other…
Building an AI Chat Assistant with Agentic LLMs and Multi-Tool Integration Introduction In this rapidly evolving era of Artificial Intelligence, I wanted to go beyond simply learning about AI and start understanding how it works in real-world applications. My goal is to dive…
Open your site on a phone and try to tap the "×" that closes a banner, the edit icon in a table row, or the second of three pagination numbers. If you hit the wrong one, or have to zoom in first, the target is too small. People with tremors, limited dexterity, or a phone in one…
You open localhost:3000 and it's the wrong app. Or npm run dev says the port is taken, and lsof tells you it's node . Every dev server is node . What you actually need is the folder it was started from. macOS doesn't have Linux's pwdx , but lsof can tell you, and it takes about…
You finished the degree, the bootcamp, or the 100 tutorials. You open LinkedIn, hit "Easy Apply" 80 times... and hear nothing back. It's not just you. The market in 2026 is weird. Overall software hiring is growing again, but the classic junior job ("here's a ticket, build this…
CCTV Storage Math: H.265+ Compression Ratios, Bitrate Bitmaps & NVR HDD Sizing By Gary Pearce — Lead Electronic Security Engineer at ADI Communications (Direct: 07860 244 274) When deploying a multi-channel 4K commercial or domestic CCTV system, sizing the NVR's surveillance…
Disclosure: I made Purupuru Maker , the browser tool this post is based on. "Purupuru" (ã·ã‚‹ã·ã‚‹) is the Japanese onomatopoeia for something soft and jiggly, like pudding, cheeks or a jelly cat. The tool does one thing. You paint where a still image should wobble, preview…
PHP2Shell, a pair of unauthenticated php remote code execution flaws in PHP's core, leaked online a day ahead of its planned disclosure, and PHP's own security team has confirmed that the interim workaround circulating since the leak doesn't actually close both bugs.…
The State of Voice AI in 2026: Trends and Predictions Voice AI has gone from “nice‑to‑have” to “must‑have” in just a few short years. If you’ve been tinkering with text‑to‑speech (TTS) or voice cloning in 2023, you’ll feel the difference in the sheer speed, quality, and…
Quando acessamos um site, nosso navegador pode compartilhar mais informações do que imaginamos. Sistema operacional, resolução da tela, idioma, fuso horário e até características da renderização gráfica são alguns exemplos. Individualmente, essas informações podem parecer pouco…
Originally published on headlark.com . Docs sites grow by copying pages. A new section starts as a copy of an old one, every product area gets an "Overview" and a "Configuration" page, and the framework fills in whatever the front matter leaves out. The result is dozens of pages…
When you develop a multi-tenant application, it's easy for the code of your central application to get entangled with the tenant code. Or you start splitting everything into Central and Tenant folders. Models |-> Central |-> Tenant but there is a better way: modules. In this…
For years my color workflow was this: see a color I liked, open Figma, draw a rectangle, eyedrop the color into it, type the hex code underneath. Repeat until the file was a mess of rectangles. Color picker apps solved half of it. They pick a color and copy the hex code, and…
Hey everyone 👋, If you’re building AI apps today, you probably know the headache of API fragmentation. You might want to use GPT-4o for reasoning, Claude 3.5 for coding, and Llama 3 for fast, cheap processing. But doing this currently means: ❌ Managing 5+ different provider…
Why Text‑to‑Speech Matters Today If you’ve ever built a chatbot, an accessibility feature, or a voice‑enabled game, you know that a natural‑sounding voice can turn a static experience into something engaging and human‑like. Modern TTS engines are no longer limited to robotic…
I've been working on PeekLaunch , a weekly launch board where makers submit a SaaS or AI tool, it goes live on that week's board, and other builders upvote, rate, and review it. On paper it's a simple CRUD app. In practice, a launch board is a caching puzzle. The pages are read…
When users need to redact sensitive data from a PDF—such as tax returns, medical records, or legal contracts—they often rely on online web utilities. However, most free PDF redact tools on the web perform visual masking , simply drawing a black rectangle ( #000000 ) over the…
Location : Worldwide / Remote Employment type : Full-time or Contract Experience : Mid-level to Senior (flexible for the right candidate) About ELO ELO (Effortless Order) is building a digital commerce ecosystem designed to connect merchants and consumers more directly,…
I Built ContextKeeper to Stop Losing My Browser Tabs Have you ever opened your browser to work on one thing, only to end up with dozens of tabs open? Documentation, GitHub issues, tutorials, dashboards, research pages—and somehow, all of them feel important. Closing the browser…
Every admission season in Pakistan, students across the country ask the same question: “Merit kitni banegi?” ( What will my merit be? ) The answer should be simple. It isn’t. Every university combines Matric, Intermediate and entry test marks with its own weights, and some add…
Marketplace image checks are usually automated, and "looks white" is not the same as "is 255,255,255". If you process product photos in a browser, this is a five-line check worth adding to your pipeline. Why the naive check fails Monitors and image previews apply gamma and…
At TGScope we built a semantic map of 3 million public Telegram channels. Channels that talk about similar things sit next to each other, so the whole ecosystem is visible at once: from big regions like crypto or news down to tiny niches. Try it: tgscope.io/map We had one hard…
Hey Devs, As an indie hacker, I got tired of manually digging through Google Search Console every week to find "striking distance" keywords (rankings 11-20) and indexing issues. So this weekend, I decided to build a micro-SaaS to automate it. I wanted to share the stack I used…
imgtranslator.com translates the text in an image and redraws it in place: a menu, a product photo, a manga page. OCR and translation run on a server. Erasing the original text and typesetting the translation happen on a canvas in your browser. That erasing step is the subject…
Most Firefox extension tutorials start with a framework. React, Vue, Webpack, TypeScript — before you've written a single line of extension-specific code, you're configuring build pipelines. I took the opposite approach when building Weather & Clock Dashboard : zero…
I'm a solo developer, and over the last while I've shipped three small free games that run entirely in the browser, with no download and no signup. Here is what each one is and what I learned making it. 1. 2 Minute Drill — NFL two-minute strategy 2 Minute Drill drops you into…
This post first appeared on SportsAPIs.dev . What is an Esports Odds API? An esports odds API provides programmatic access to betting odds for competitive gaming events. These APIs cover major esports titles like League of Legends, Counter-Strike 2 (CS2), Dota 2, Valorant, Call…
Building Chrome extensions in 2026 comes with a completely new set of architectural challenges and opportunities. With Google's complete transition to Manifest V3 , developers can no longer rely on background persistence or arbitrary remote code execution. Rather than seeing…
AI assistants can write code in seconds, but speed only helps if you can trust what lands in your project. Here is the short checklist I run through every time. Read it like a pull request from a new teammate. Don't paste and move on. Read every line and ask whether you could…
Building Brief: A Zero-Backend, Sub-Second AI Note Distiller Powered by Groq ⚡ Every day, students, developers, and researchers copy-paste massive blocks of text into AI chatbots, waiting 10+ seconds for a generic summary while worrying about data privacy. To solve this, I built…
You’ve probably hit this subtle bug before: you write some CSS using logical properties like margin-inline-start , expecting your layout to just work regardless of text direction. But then you flip your app to RTL or switch writing modes, and suddenly things don’t line up as you…
Chrome extensions let developers customize the browser, automate repetitive tasks, and build useful tools that improve everyday workflows. With JavaScript, HTML, and CSS, you can create everything from productivity helpers to advanced browser integrations without building a…
What Running a 200-Game Browser Arcade Taught Me About Instant-Play UX I help run PlayPokiGame, a free collection of a few hundred casual HTML5 games you can play right in the browser — no downloads, no signups. After watching how real players actually use it, I've developed…
iPhones save photos as HEIC by default. They are about half the size of JPG, but many websites, forms and Windows apps cannot open them. A common request is "let users upload an iPhone photo", and most upload forms reject .heic . You can convert HEIC to JPG entirely in the…
In 1787, Thomas Rowlandson drew an ox loose on Westminster Bridge. Hats flying, people climbing the railings, total panic. That's roughly how it feels to drop a Rust linter into a five-year-old JavaScript project. Oxlint and Oxfmt are the linter and formatter from the Oxc…
The top DNS providers of .com are GoDaddy, with 21.66% of names, and Cloudflare, with 12.94%. Together they run about a third of the zone. We counted all 167 million names on 8 October 2026, each under the provider of its first nameserver. Who are the top DNS providers in .com?…
Your AI feature works and the demo looks great. One question before you share the link: where does your AI API key live? If you built your app with Cursor, Claude Code, Lovable, Bolt, Replit or v0, there is a real chance the answer is "in the browser". That means anyone who…
Every experienced pizza baker knows that recipes measured in cups or tablespoons are doomed to fail when ambient humidity or room temperatures fluctuate. Great pizza is an exact science rooted in Baker's Percentages and fermentation kinetics. When we set out to build PizzaMate…
Timing-Based Username Enumeration Most modern apps return generic "invalid credentials" messages, but the response time tells a different story. When bcrypt processes a valid username, it takes ~200ms to hash and compare. Invalid usernames skip this entirely. Measure the…
I spend a lot of time in the AI space -- reading papers, building things, talking to engineers who are actually shipping. And there is a gap between what the demos show and what production systems actually look like that nobody is being fully honest about. So here is my honest…
Newsrooms are racing to deliver breaking stories in real‑time, and one of the newest weapons in their arsenal is AI‑generated voice. Whether it’s a 911 alert, a live‑stream commentary, or an automated recap of an event, text‑to‑speech (TTS) and voice cloning let journalists…
Bagaimana internet, perangkat pintar, dan layanan digital mengubah kebiasaan kita—serta apa yang perlu dipahami agar tetap aman dan kritis. Ketika mendengar istilah transformasi digital , kita mungkin membayangkan kecerdasan buatan, komputasi awan, atau perangkat canggih.…
If you built anything on eBay sold prices before 2025, you probably had a findCompletedItems call somewhere. It stopped working, and the obvious replacements do not return sold data. This post covers what still works in 2026, how to call it from Python, and how much the results…
A short link app has a simple job: count the clicks and bill the owner for them. The app counts each click in its own database. The billing provider keeps a second count, called a meter, and the invoice comes from the meter. Both counts start equal, but nothing keeps them equal.…
Why Testing AI‑Generated Voice Content Matters Text‑to‑speech (TTS) and voice‑cloning have moved from novelty to production‑grade components in everything from interactive assistants to audio books. But a synthetic voice that sounds great in a single demo can still break in…
Most code reviews are theater. A thousand-line pull request lands on Friday, sits untouched for four days, and merges on Monday with two approvals from people who skimmed it. Nobody found a bug, nobody learned anything — the diff was too big to understand, so the approval was a…
I have audited hundreds of forms for WCAG compliance, from local service sites with a single contact box to multi-step insurance quote flows. The pattern I see most often is a form that looks fine on a desktop screen and falls apart completely the moment a screen reader gets…
The Decision Behind the Markup Your help center is no longer read only by humans. Chatbots, browser agents, and search summarizers scrape it and answer on your behalf - without your support tone, your escalation paths, or your legal review. So product teams face a real choice:…
What is a Podcast Intro Generator? If you’ve ever launched a new show, you’ll know the first 30‑second hook is everything. A polished, brand‑consistent intro sets the tone, tells listeners what to expect, and can even boost discoverability. Building a “Podcast Intro Generator”…
