Hey tech community - quick question!

For technical video training content you use for professional development, are the supplemental materials like labs, self-assessments, reading assignments, etc useful, or do you prefer to simply watch the videos and take your own notes?

So apparently there's only one form of weather left in the US northeast.

Rain, followed by more rain, and when the rain finally lets up, rain.

For formal technical training videos that you'd actually pay for, other than video of the instructor in the intro, do you care about seeing the instructor in the corner during the actual lesson?

What do you prefer for the format? Is the talking head important at all if the training content is good?

New Post: MCP Is Unnecessary

I can’t think of any strong technological reasons for MCP to exist. There’s a lot of weak technological reasons, and there’s strong sociological reasons. I still strongly feel that, ironically, it is necessary.

Big AI news! OpenAI has released three new models: GPT‑4.1, GPT‑4.1 mini, and GPT‑4.1 nano which (according to what I read so far) offers major improvements in coding, instruction following, and long-context comprehension

Yes, the next model after 4.5 is 4.1 😆
