.SYNOPSIS
    Removes outdated podman or docker images, keeping only the newest tag(s) per repository.

.DESCRIPTION
    Groups every tagged image by repository, orders each group by creation date and
    removes everything past the newest -Keep tags. Repositories with a single tag
    (base images such as mcr.microsoft.com/dotnet/sdk) are therefore never touched.

    Images referenced by a container - running or stopped - are always skipped, and

## 第 0 章 · 先建立正确的心智模型

初学者最容易犯的错误，是把这三个工具当成"三个差不多的东西"，结果每个都学了一点、每个都不会用。它们其实分工不同，记住下面这句话你就不会迷路：

**Similarweb 帮你看"整个市场和对手长什么样"，Ahrefs 帮你把"关键词和外链这两件事做到最深"，SEMrush 帮你把"从调研到执行到追踪的全流程串起来"。**

| 工具 | 一句话定位 | 最强的地方 | 在你的 SEO 流程中主要负责 |
|------|-----------|-----------|------------------------|
| **Similarweb** | 市场与流量情报 | 估算任意网站的总流量、流量来源构成、受众画像、行业大盘 | 竞品调研、市场规模判断、找到"真正的对手是谁" |

1) Para reemplazar en todo el buffer con nada

:%s/''//ge


2) ^G (control G) Muestra info del buffer

3) :n Pasa al siguiente buffer

4) :N Pasa al buffer anterior

5) Marca una posicion del buffer con una letra

   m Letra  
   Ejemplo: mt 
   Luego presionando t uno va a la posicion donde se puso la marca.

6) Para traducir TABs a espacios poner
   :set expandtab

7) Si la linea no entra en la pantalla porque es muy larga, en vez de mostrarla abajo q continue.

   :set nowrap

I'm learning for Azure Certification AI-200. Summarize the following learning material, but not too short. keep all the relevant terms and explanations. Highlight the most relevant exam points.

 

### SQLAlchemy
- Wrapper used to connect python code to a database via SQL
- `pip install Flask-SQLAlchemy`

### Workflow
- Connect to SQLite database
- Set up a model in Flask app
- Perform basic CRUD operations

### Connecting to SQLite DB
```py
import os # allows to read file paths
from flask import Flask
from flask_sqlalchemy import SQLAlchemy

# set up db
basedir = os.path.abspath(os.path.dirname(__file__))
# __file__ -> when loaded into python, this variable is assigned 
# to the filename 

async function setCookieHomeAnimation() {
  // console.log('setCookieHomeAnimation')
  "use strict";
  let homeShowCookie = await cookieStore.get("homeShowCookie");

  // if cookie exists, hide element (or perform other code)
  if (homeShowCookie) {
    document.getElementById('intro-view').classList.add('hidden');
    return;
  }
  // otherwise, show animation
  document.querySelector('body.home header.banner .text-wrapper').classList.add('intro-show');

PRD: V1 Agent-Powered Agency Platform

Status: Implemented (V1 prototype)
Project: fabel
Version: 1.1
Last updated: 2026-07-15



1. Problem Statement

Design/development agencies spend significant manual effort on repeatable knowledge work: researching prospects and clients, drafting outreach, composing project briefs, planning technical builds, and QA-ing deliverables. Each of these tasks is well-suited to a specialized AI agent, but ad-hoc scripts and one-off prompts don't compose: outputs ar

# React Router v7 + RSC Deep Dive

**Stack:** React Router v7 (unstable RSC Framework Mode) · React 19 (`Suspense`, `use`, `ViewTransition`) · Better Auth · MongoDB Atlas · Mastra.ai RAG agent

**Research date:** 2026-07-15  
**Audience:** Engineers scaffolding a production-shaped app that can also become a multi-post teaching series  
**Status note:** React Router’s RSC APIs are **experimental** (`unstable_*`). Pin versions tightly and re-read release notes on every bump.
