Adafruit GFX is the layer nearly every Arduino display library sits on top of. Adafruit_SSD1306, Adafruit_ILI9341, Adafruit_ST7735, the e-paper libraries and dozens of third party drivers all inherit from it, which is why the same drawLine call works on a 128x64 monochrome OLED and on a 320x240 colour TFT. The catch is that the drawing functions live in the base class while the colours, the constructor and the buffer behaviour come from the driver. That split is where most of the confusion comes from. This guide covers the whole API in one place. ...

The 0.96 inch blue OLED is a staple of Arduino projects. It is cheap, it needs two wires, and because it has no backlight its black is genuinely black. Yet half the people wiring one up for the first time end up staring at a blank panel. This guide runs end to end: picking the module, wiring, finding the I2C address, choosing a library, drawing text and shapes, showing bitmaps, building an animation, and fixing the six problems that come up most often. ...

The list that pops up when you hit / in Claude Code is intimidating at first. A hundred-odd commands, half of them named in a way that gives nothing away, and your own custom commands mixed in with the built-ins. You don’t need all of them. Ten commands cover almost everything you do day to day, and the rest is reference material you look up when the moment arrives. This page gives you both: the ten first, then the full list grouped by what it’s for 🧰 ...

Summary: Qwen3.8-Max in 30 Seconds Qwen3.8-Max is Alibaba’s new flagship model, made generally available on August 2, 2026. 2.4 trillion parameters, 95 billion active (MoE architecture). It reads text, images and video, and returns text. Context window is in the 1 million token class. On one task it ran 125 hours (about 5 days) with no human input, rebuilding an experiment from a machine learning paper from scratch, confirming its six findings, then inventing a method that beats the paper. It beats Claude Opus 4.8 on most coding and agent tests, trades blows with Claude Fable 5 and GPT-5.6 Sol, and falls behind on some. API pricing is $2 input / $6 output per million tokens. Repeated input costs $0.25. This is the first time Alibaba has open-weighted a Max-class model. The weights landed on Hugging Face on August 12, 2026, though under Alibaba’s own Qwen3.8-Max license rather than Apache 2.0. Two days later, on August 14, Qwen3.8-27B followed: a dense 27B model under Apache 2.0 that fits on a single GPU. Ask an AI to “rebuild the experiment in this paper, then improve on it” and it normally stalls after a few turns, waiting for you to step in and steer. ...

You want to tell an AI “read this file”, “pull that record from my database”, “close this issue”. The model cannot do any of it on its own, because it has no access to your machine, your database or your accounts. MCP exists to close exactly that gap. It puts a standard connection layer between the AI application and the outside world 🔌 What Is MCP? MCP (Model Context Protocol) is an open-source standard for connecting AI applications to external systems. ...
