How I built a production mobile app boilerplate in two weeks without writing a line of frontend code Eight months ago my wife and I had twins. The baby tracker apps on the App Store weren't designed for multiples. Most were paid. The free ones were missing things. None of them thought about two babi
Last fall I shipped a fully functional iOS app — from zero code to live on the App Store — in a single weekend. Here's exactly how it happened, what tools I used, and the honest parts that were harder than expected. I wanted a dead-simple countdown app. Not the bloated ones on the App Store with 47
A deploy can pass every technical check and still make the product worse. The build succeeds. The Vercel deployment is green. Sentry is not on fire. Nobody is in incident mode. Then the next morning signup looks softer, checkout has a weird dip, or onboarding completion is lower than it should be. T
I Built 9 Production-Ready Telegram Bots in Python TL;DR: I just open-sourced 9 different Telegram bots — AI assistant, booking bot, crypto alerts, job vacancy channel, price monitor, restaurant bot, tutor bot, survey bot, and auto-content channel. All free to use. After dozens of freelance Telegram
Execution context và call stack: đọc được stack trace là kỹ năng debug nền tảng Mỗi khi một hàm JavaScript chạy, engine tạo ra một execution context cho lần gọi đó — một khung chứa thông tin về scope, giá trị this, và các biến local. Các context này được xếp chồng lên nhau trong call stack. Hiểu rõ
Comedy of Errors I recently added Google login to an Angular app backed by IdentityServer. Simple enough on paper. Took me almost two days. The Setup Stack: Angular 20 (standalone), angular-auth-oidc-client v21, IdentityServer8, ASP.NET Core. Google OAuth configured on the backend via .AddGoogle().
Target built a generative AI system to improve marketing campaign forecasting by retrieving and ranking similar historical campaigns. Using embeddings, vector search, and LLM ranking, it replaces rule-based workflows. Evaluation shows 75% top-1 and 100% top-3 coverage. The system reduces manual effo
Hoisting và TDZ: vì sao biến ra undefined thay vì báo lỗi Trước khi chạy bất kỳ dòng code nào trong một execution context, engine có một pha quét toàn bộ scope để đăng ký các khai báo. var và function declaration được đăng ký và khởi tạo ngay trong pha này; let, const, class cũng được đăng ký nhưng
For most of its life Rocket Lab has sold the picks and shovels of the space economy: small rockets, satellite buses, components for other people’s missions. It has now decided that selling the tools is not as valuable as owning the mine. The company agreed to acquire Iridium Communications for about
RELX does not make headlines the way a chip foundry or an AI lab does, which is rather the point of the business. It sells data, analytics, and the dull certainty of recurring revenue, and it returns the proceeds to shareholders on a metronome. The latest beat of that metronome arrived this week. Th
Google is adding SandboxAQ’s ‘large quantitative models’ to its cloud marketplace, pairing Gemini with AI trained on scientific equations and laboratory data. The large language models that power most of the AI industry are very good at words and surprisingly unreliable at numbers. Google’s latest m
The unglamorous truth about the AI boom is that some of its hardest problems are plumbing. As data centres pack more GPUs into every rack and run them hotter, the fluid that keeps the chips from cooking has started, occasionally, to grow bacteria. That is the problem Omen AI has built a company arou
Dina Gazzella is 85, and on her wrist is a small black band that looks like a watch and does rather more than tell the time. “If I feel unwell, this is a lifesaver,” she told Reuters. In a summer that has turned lethal across Europe, that is not a figure of speech.The bracelet is […] This story cont
Written by: James Sadowski, Alden Wahlstrom Introduction Four years into Russia’s full-scale invasion of Ukraine, the pro-Russia influence ecosystem has evolved from a tool of war back into a global strategic asset. Since the mobilization of this ecosystem to support frontline objectives, we have wi
I completed Module 3, Working with your own data and documents in Python. I ran all the code and at the end of each exercise it displayed all tests passed. I submitted the assignment and got zero points per exercise. Each exercise displays the same error message: name ‘key_topics’ is not defined. Th
