When you build a checkout form, you need card numbers to test it. The usual shortcut is to type 4111 1111 1111 1111 or make up some digits. That works until it doesn't, so here is what actually matters. Random digits…
int age = 25; int *value = malloc(sizeof(int)); *value = 100; O que muda entre essas duas alocações? Se você já programou em C, provavelmente lembrou de stack, heap, ponteiros e da necessidade de chamar free. Se…
Automated weekly digest from pkgdrift — LLM-refined package intelligence across npm, PyPI, Cargo (Rust), and RubyGems. Pipeline runs every 6 hours. This Week's Signal 15 packages tracked across alpine, cargo · 3 showing…
Grading a stack of tests is repetitive: count the misses, convert to a percentage, look up the letter, repeat. It's a nice small project because the logic is tiny, but a few details decide whether the tool feels good to…
Originally published at tensorust.com. TL;DR: On October 17, 2026 I asked three small language models for JSON 432 times, in a real Chrome tab, with the exact sampling settings my browser chat app ships. Llama 3.2 1B…
Type-Safe Web Scraping for AI Agents: Integrating Firecrawl into a TypeScript Monorepo When building AI agents that need fresh web data, you hit two friction points fast: runtime API shape drift and monorepo cache…
When you answer someone's question on a forum, the date of the post tells you less than you think. A founder told me their replies stopped working after day 5 to 7. By then the person has picked a tool or moved on, and…
In July 2026, Telegram began inviting some of its contest participants into a private Serverless test. The pitch is straightforward: put your bot's code and database on Telegram's infrastructure. On October 6, Mini App…
On 20 September 2026 we fetched 120 sites made with AI app builders the way AI crawlers do: plain HTTP, no JavaScript. 61% of the live ones were empty. The data, the control group and the fixes. On 20 September 2026 we…
Integrating external payment gateways like Stripe and Adyen into a TypeScript-driven financial architecture represents one of the most demanding challenges in software engineering. When building high-reliability payment…
Most Three.js configurator demos stop at the visual. The customer rotates a nice model, picks a color, and that is the whole show. But the manufacturers I build for do not sell models. They sell a product with a price…
TL;DR: Propagate one request_id from browser fetch calls into Node.js logs when you need a lightweight way to reconstruct a flagged pricing request. Keep the payload sparse, decide its region and retention before…
Every soundboard eventually gets the same request: "Can I add my own?" Someone wants their own catchphrase as a button, or a short voice note they can replay for the group. Recording audio in the browser is easy to…
Adobe's free page-number page still uploads the PDF, then asks you to sign in. I read their steps again today. Smallpdf's page says the file is uploaded and deleted after an hour, unless you save it to an account.…
When someone saves a note in your app, it usually travels to your server over HTTPS and then sits in a database as plain text. HTTPS protects it on the way there. After that, anyone who can run a query can read it, and…
Paste a real sample and generate the interfaces, then check the few things a generator can't know from the data: optional fields, nulls, empty arrays and dates. JSON to TypeScript turns sample JSON into interfaces or…
If your Node.js code reads Google's daily trending searches with google-trends-api, it probably fails like this now: SyntaxError: Unexpected token '<', "<!doctype "... is not valid JSON The call itself does not throw.…
My new portfolio has a small daily arcade: Minesweeper, a 6×6 Sudoku, Quick Math and Code Review (spot the bug in three short snippets). Everyone gets the same puzzles each day, and I play them first, so my real time is…
You open a WebSocket to a speech-to-speech model, start streaming your microphone, and three things go wrong at once: the model answers itself because it hears its own voice through your speakers, your transcript prints…
