I Replaced $800/mo in API Costs with a Local Llama 4 Setup for E-Commerce

My team runs an e-commerce operation that pushes around 80,000 product descriptions through LLMs every month. We were spending $800+ on GPT-4o API calls. Last month we moved the bulk generation pipeline to Llama 4 Maverick running locally via Ollama. Monthly cost dropped to about $40 in electricity. Here's the full setup, what worked, what didn't, and where we still use cloud APIs. Why ...

Dev Tools para Todos

Como desarrolladores, no todo lo podemos resolver escribiendo código. Algunas veces hay cierto tipo de problema que se resuelve con una herramienta externa. Y no hablo de integraciones con APIs de terceros. Hablo de cosas sencillas como pasar un contenido de un tipo a otro. Un mal ejemplo sería pasar un documento PDF a Word. ¿Por qué haríamos eso? No sé pero a veces toca ese tipo de cosas. A vece...

How do I return extra properties in abp framework's autocomplete select?

So ABP has a kind of helper to select elements that uses select2 under the hood. I already consulted the docs but didn't find anything. So basically I have a cshtml element that looks like the default element in ABP's autocomplete manual, but the problem is that only a property for the id and one for the text can be returned (autocomplete-display-property-name and autocomplete-value-property-name)...

Congrats to the April Fools Challenge Winners!!

We asked you to build something completely useless and you delivered. The DEV April Fools Challenge brought out some of the most hilariously over-engineered, magnificently pointless, and genuinely funny software we've ever had the pleasure of judging. We laughed, we scratched our heads, and we asked "why on earth did they build this?" Thank you to everyone who participated. Your willingness to ...

PromptOpsKit: an open-source, repo-native way to manage prompts in AI apps

I got tired of prompt & system instruction, models, tools, and input context strings scattered across my app, so I built PromptOpsKit (or see this website) npm i promptopskit If you build AI features into a real product, you probably already have prompt operations. You just don’t have them in one place. A typical feature ends up spreading behavior across: a prompt string in one file mode...

I built a new file format to cut AI token costs by 70% — here's how it works

Tags: #ai #webdev #javascript #opensource #ChatGPT #Claude #Copilot #Gemini Every time I pasted a spreadsheet or XML file into Claude or ChatGPT, something bothered me. I was burning tokens on things the AI didn't need. A 120-row sales CSV with 10 columns repeats the column names 120 times. An XML response from an enterprise API can spend 40% of its tokens on namespace declarations like xmln...

💻 Learning Cybersecurity by Building- A Hacker Terminal Game in Python

🚀 Introduction (The "Why") As I started learning cybersecurity, I realized that just reading concepts or watching tutorials wasn't enough. Topics like password security, encryption, and system monitoring only truly make sense when you apply them. So instead of building a typical beginner project, I decided to create something that would both- -Reinforce what I've learned -Help other beginners unde...

Claude Code Felt Off for a Month. Here Is What Broke.

For about four weeks in March and April, Claude Code felt noticeably worse. I was not imagining it. Sessions got repetitive. Tool calls chose weird paths. My usage limits emptied faster than the work I got out of them. I kept switching models, clearing context, restarting CLIs, convinced I had broken something in my own setup. Then on April 23 Anthropic published a postmortem. Three separate bugs...

How to Make Illegal States Unrepresentable

A couple of years ago, I wrote that The Builder pattern is a finite state machine!. A state machine consists of states and transitions between them. As a developer, I want to make illegal states unrepresentable, i.e., users of my API can’t create non-existent transitions. My hypothesis is that only a static typing system allows this at compile-time. Dynamic typing systems rely on runtime validatio...

One PR to a parser unlocked prerendering in Brisa

I built a JavaScript framework called Brisa. The kind of framework that needs to parse every single source file your app contains; analyze imports, detect server vs. client components, inject macros, transform JSX. All of that happens at the AST level. Before Brisa, I was already maintaining next-translate, an i18n library for Next.js. For the plugin that auto-injects locale loaders into pages, I...

I built a VS Code extension that scaffolds React Native MVVM features in one command

Every React Native developer knows this ritual. You need a new screen. So you open an existing feature folder, copy the files, rename them one by one, fix the broken imports, delete the leftover logic, and spend 15 minutes doing work that has nothing to do with what you actually wanted to build. I got tired of it. So I built a VS Code extension to fix it. What it does React Native MV...
