Steam Machine Review: This Device May Also Influence XR

Photo of Steam Machine

The long-rumored Steam Machine suddenly went on sale on June 23. Personally, I thought it would launch around the same time as Steam Frame, meaning a little later, so it caught me completely off guard. But I had already decided before launch that I was going to buy it, so I went to the sales site on release day and purchased one. It arrived on June 30. I have spent some time setting it up, and now that a few things have become clear, I will write a review.

Making Setup Easier: Seiro MCP v0.5.0 Released

Sometimes I wonder whether Seiro MCP is still necessary now that even Xcode has MCP. But from the perspective of autonomous coding, I think Seiro MCP has the advantage of being lightweight and easy to handle. In that sense, there is still plenty of room to improve it as a product, which led to this release. This update adds fixes and features with the stance of making setup as easy as possible.

Calling for Codex + visionOS Talks. I Plan to Talk About Various Development Styles

On the event page for the first Codex + visionOS Hack #1 @ Motoyawata, we are looking for Codex / visionOS talks. This time, I want to write about talks at "Engawa AI x XR." More than anything, I want to lower the barrier to giving a presentation. Through attending and speaking at various events so far, one thing I have felt is that there is often quite a gap between speakers and participants.

Starting a Study Community Called Engawa AI x XR

Exterior of Co,do

I decided to try starting an AI x XR study community in my local Chiba Prefecture. I will write about the background and how this came about, including why I chose Motoyawata in Chiba as the base instead of Tokyo, which would be more advantageous for attracting participants.

I Finally Hit a Major Milestone While Still Active as an Implementer

People call turning 30 a major milestone, and they say the same about turning 40. Here, the milestone means turning 50. Today, March 11, I finally turned 50. For the past 15 years, it has become my birthday routine to watch special programs about the Great East Japan Earthquake, look back on the past, and think about my own future.
