This is the Motorola Edge 70 Pro. It launched back in April, and it costs €540 with 8GB of RAM, and 256GB of storage. Depending on the location, there are a few Pantone colors to choose from: Titan, Zinfandel, Lily White, and Tea. In the box, you'll find the phone, a USB-C cable, and a hard case wit
So far we have seen the planner build candidate paths and rank them by cost, choose join methods and join orders, and estimate those costs from statistics. But before any of that cost comparison begins, the planner does something else first. It takes the incoming Query tree and rewrites it once into
The Quest Begins (The "Why") I was building a simple rate limiter for a side‑project API. The idea was dumb‑simple: every time a request came in, I’d insert a row into a request_log table with the user ID and a timestamp, then count how many rows existed in the last minute to decide whether to allow
Everything from 1.4.1 through 1.4.9 happened inside a single function, standard_planner(). Building paths, costing them, searching for a join order, estimating cardinality from statistics: all of it runs inside that one function. Yet PostgreSQL does not call standard_planner() directly. It puts anot
By the time 1.4 ends, the planner has produced one PlannedStmt. Inside it is an execution tree built from Plan nodes, frozen into a form you can follow step by step, something like "go into the primary key index on users, fetch the one matching row, then output that whole row." But that is still onl
Gelişmiş Veri İşleme (Python) Sıralama, Filtreleme ve Arama – Profesyonel Veri Manipülasyonu Rehberi Python’da veri işleme, sadece döngülerden ibaret değildir. Modern Python yaklaşımı; fonksiyonel programlama araçları, yüksek seviyeli built-in fonksiyonlar ve lambda ifadeleri ile daha kısa, daha oku
You've probably seen that trending post — "I Asked AI to Write My Commit Messages and It Was Embarrassing." Same. But instead of accepting embarrassing output, I fixed it. Here's the thing: the problem isn't AI writing commit messages. The problem is how you ask it. One clear system prompt + the act
A scan node sits at the leaf of the tree and pulls rows from a single table. A join node sits in the middle and brings together the rows that its two children send up. It takes one row from users, one row from orders, checks whether they belong to the same user, and if they match, emits the combined
We opened Chapter 1 with a single line, SELECT * FROM users WHERE id = 1. For that line to leave the client and come back as a result row, the PostgreSQL backend went through five stages. First it decided which processing path the message should take; then the parser and analyzer turned the text int
You wrote a detailed CLAUDE.md, and Claude Code still gets things wrong — wrong convention, touches files it should not, ignores rules you clearly wrote down. The cause is almost never that the rules are missing. It is that they are buried. CLAUDE.md loads into Claude's context every single session,
I spent the last several months solo-building Tuneline, a cross-platform media player, from a single Flutter codebase that ships native apps to macOS, Windows, Linux, Android, Google TV, and iOS. No Electron. Here is the stack and a few things that bit me. Flutter 3.38 / Dart 3.10 — one codebase, si
The Tailwind CSS4 debate is everywhere right now. And honestly? Most people are arguing about the wrong thing. The real question isn't "inline styles vs. utility classes" — it's about where your styling decisions live and who pays the cognitive cost. Let me break down what's actually happening, with
If you use Claude Code, there is one file that quietly shapes every session: CLAUDE.md. Most developers either do not have one or have one that works against them. Here is what it actually is, in plain terms. CLAUDE.md is a markdown file that Claude Code reads at the start of every conversation. Thi
A Japanese corporate pension fund serving about 1,200 small and medium-sized businesses plans to allocate roughly 1% of its assets to crypto as part of a currency diversification strategy.
The Delhi high court on Friday said the government had sufficient material to justify the blocking order of Telegram. What are the implications of the ruling for other messaging apps?
₹1,20,000. That's how much a client spent building an automated follow-up system I had to tell him to rip out thirty days later. I'm an automation consultant. My entire business depends on people wanting to automate things. And yet, the most valuable advice I give — the advice clients actually remem
The Concurrency Collision As your B2B SaaS platform at Smart Tech Devs scales to handle thousands of concurrent operations, you will inevitably encounter the most frustrating database error in backend engineering: the Deadlock (e.g., PostgreSQL 40P01: deadlock detected or MySQL 1213 Deadlock found w
₹47,000 every month. That's what my friend Rohit was paying a fund advisory service to tell him which stocks matched his criteria. Six filters — RSI below 40, volume spike above 200% of 20-day average, 200-DMA crossover, sector rotation signals, delivery percentage above 60%, and promoter holding ch

The Unmounted Component Trap In highly interactive dashboards at Smart Tech Devs, users navigate quickly. Imagine a user clicks a "Generate Heavy Report" button, which fires an API request that takes 4 seconds to resolve. After 2 seconds, the user gets bored, clicks the "Back" button, and navigates
