I cancelled YouTube Premium last week. The thing that replaced it costs nothing, runs in any browser, and was built by 361 volunteers on GitHub. Invidious does the four things people actually pay Premium for. No ads. Background audio on mobile. Watch without an account. Privacy from Google's tracking. All of it, free. The part that surprised me most is how clean the experience is. The entire page renders without JavaScript. Pages load in milliseconds because there's nothing to load. No tracking pixels. No autoplay traps. No recommended-for-you algorithm trying to swallow your evening. You can: → Subscribe to channels without a Google account → Get notifications when they post → Import your full YouTube subscription list in one click → Switch between dozens of public instances if one goes down → Self-host it on a $5 VPS if you want full control → Use it with the Privacy Redirect extension to auto-redirect every YouTube link The repo has been actively maintained for years. Latest release was February 2026. 100% Opensource.

Type-C 线长得都一样，但能力天差地别，哪根能跑满速，哪根只能慢充，完全分不清。 于是找到 WhatCable 这个开源小工具，插上线后会用大白话告诉我们这根线到底能干什么。 它直接读取系统底层的端口信息，把线缆的真实速率、充电功率、连接设备都翻译成人话展示出来，不用翻任何设置。 GitHub：github.com/darrylmorley/w… 最实用的是充电诊断功能，能直接告诉我们这条线限制了充电速度，还是充电器功率没跑满，精准定位瓶颈。 支持 Homebrew 一键安装，还附带命令行工具。如果你 Mac 桌上堆了一堆 Type-C 线分不清好坏，装一个就明白了。

A Anthropic acabou de matar o Markdown. Um engenheiro do Claude Code publicou um artigo ontem que pode decretar o início de uma nova era. A tese é brutal: Markdown nunca foi o formato certo para comunicação entre humanos e IA. Era só o que tínhamos. O próprio autor admite que nunca leu um arquivo Markdown gerado por IA com mais de 100 linhas até o fim. Você também não lê. Eu também não. A sacada: Markdown assume que você vai ler do início ao fim. HTML assume que você quer ver o que importa e mexer com as mãos. Na prática: → 30 tickets de projeto viram kanban arrastável com colunas Now / Next / Later / Cut e botão de exportar → Lógica de rate limiting vira flowchart SVG com código inline, no lugar de 200 linhas de texto → Code review vira diff colorizado com grafos de dependência entre módulos → Parâmetros de animação, cores, regex, cron jobs ganham sliders com preview ao vivo → Specs de projeto viram 6 opções lado a lado com mockups interativos Todos exemplos reais do artigo. Todos substituem um muro de texto por algo que você de fato abre e usa. O trade-off existe: HTML é 2-4x mais lento para gerar. Mas com contexto de 1 milhão de tokens, esse custo sumiu. E a parte que ninguém está discutindo: o HTML gerado não é só para humanos. O agente de verificação também lê. O spec deixou de ser documento e virou memória compartilhada entre agentes. Markdown é relatório. HTML é interface. Relatórios são para ler. Interfaces são para continuar o trabalho. Se você usa IA em 2026 e ainda pede Markdown para tudo, você pode estar usando um smartphone como lanterna.

Microsoft open-sourced a no-code data analysis tool! You drag and drop, type what you want, and AI builds the chart, transforms the data, and writes the SQL for you. → Works on screenshots, CSVs, and live databases → Connect OpenAI, Claude, or run Ollama locally → No $70/month seat. No PhD in DAX. 100% open source.

this is illegal in 90% of cars. A developer just open sourced an app that turns any Android phone into a CarPlay device, the system Apple charges automakers millions to license. It's called OkCar. It tricks your car's head unit into thinking your Android is an iPhone running CarPlay, and your entire dashboard lights up like you just bought into the Apple ecosystem. Every Android Auto user knows the pain. You buy a car, the head unit only supports CarPlay, and suddenly your $1,200 Pixel is a worse driving experience than a 2018 iPhone SE. Automakers locked you out and Google never built a workaround. This repo is the workaround. Here's what makes it different from every half-broken CarPlay hack floating around GitHub: → Full CarPlay protocol implementation in pure Kotlin, no jailbreak, no rooted phone, no fake hardware dongle → Wireless and wired both supported, plug in over USB or pair over Bluetooth and WiFi → Native Android apps render directly onto the car screen, not just mirrored from your phone → Google Maps, Spotify, WhatsApp, Waze all work on the head unit while your phone stays in your pocket → Voice control routes through Google Assistant instead of Siri, finally Killed: $200 Carlinkit dongles, $150 Ottocast adapters, every aftermarket CarPlay box charging hardware prices for software emulation. Killed the $30K used car premium people pay just to get a head unit that supports their phone. Works on any car built in the last decade with a CarPlay-capable head unit. Toyota, Honda, Ford, BMW, Mercedes, Hyundai, Kia, Mazda, the entire industry. Apache 2.0. 100% Opensource.

处理数据时，几十 GB 的 Parquet 或超大 CSV 往往让传统软件“转圈半天”，甚至直接卡死崩溃，体验相当折磨。 我最近试了 Dataset Viewer 这款开源工具：超大文件秒开，操作顺滑得像在看普通表格。 它基于 Tauri + React 打造，轻量但很能打：100GB+ 文件几乎瞬间打开，搜索毫秒级响应，还能直接预览压缩包内容。 GitHub：github.com/stardustai/dat… 主要功能： - 超大文件秒开：100GB+ 数据集虚拟化渲染，打开即用 - 毫秒级搜索：实时定位、结果高亮，查数据不再等 - 压缩包直读：ZIP/TAR 流式浏览，无需解压也能看 - 多格式原生支持：Parquet/Excel/CSV 针对性优化渲染 - 多源数据接入：WebDAV/云存储/HuggingFace 数据集都能连 - 界面简洁好上手：深浅色主题切换，多语言支持 使用也很省心：到 GitHub Release 页面直接下载对应安装包即可，Windows、macOS、Linux 都支持。

Open-source CRM with unlimited users and Kanban boards github.com/frappe/crm

A developer just found the internet’s biggest loophole. Port 53. The one port every firewall, school network, airport WiFi, hotel router, and ISP is forced to keep open. Because the second DNS breaks… the internet breaks with it. Now a developer turned that loophole into an encrypted tunnel called MasterDnsVPN. Instead of using normal VPN protocols that firewalls instantly fingerprint and block… it hides traffic inside ordinary DNS requests. To the network, it just looks like normal DNS activity. Meanwhile, your traffic keeps flowing underneath. Why this repo is blowing up: → Uses a custom low-overhead ARQ system built specifically for unstable DNS paths → Sends packets through multiple resolver routes at once for higher reliability under packet loss → Auto-detects the best DNS payload size possible to squeeze out maximum speed → Supports AES, ChaCha20, and multiple encryption modes out of the box → Includes a built-in SOCKS5 proxy so browsers and apps work instantly No subscription. No monthly VPN fee. No bloated clients. Just configure your DNS records, add the encryption key, and run the binary. Windows, Linux, macOS, ARM64 all supported. And unlike most VPN protocols… this one survives on networks where OpenVPN, WireGuard, and Shadowsocks get killed instantly. GitHub repo: github.com/masterking32/M… MIT licensed. 100% open source.
