An engineer recently sent me some questions about the #productmanagement role. I took a long time to respond because I saw it as a great opportunity to reflect on the role and what it means to me. I decided to share my answers here, in case it’s useful for anyone else! elezea.com/2025/06/prod...

“MCP Is RSS for AI” is a good analogy, but my analogy would be that MCP is like “Dynamic FAQs”, with the difference being that any question you ask could be considered “frequent” enough to be vetted and correct. thenewstack.io/mcp-is-rss-f...

Love this take on the “10x engineer”. Ubuntu (the African principle, not the OS) strikes again… “I am because you are.” “It doesn’t matter how fast an individual engineer can write software. What matters is how fast the team can collectively write, test, […] and revise the software that they own.”

Any celebration of Reid Miles gets an automatic boost from me. Legend. “Miles fulfilled the Blue Note manifesto. His album covers pushed the envelope of graphic design just as the artists on the records inside continued to break new ground in jazz.”

Every once in a while a preorder shows up before release date and it’s always such a wonderful thing when that happens. Mdou Moctar’s band made a 4-track EP. It comes out on Friday but it showed up today and this thing goes so hard. It’s like post-punk desert blues.

Interesting data on which movies aged poorly (and well), but it’s the genre data that stood out to me. “According to our rating-change data, horror movies age notably well, while comedy and drama see a marked decline in appraisal over time.” www.statsignificant.com/p/which-movi...

I love this deep-dive on the little interjections we use in everyday speech. One example: “Other interjections serve as ‘continuers,’ such as ‘mm-hmm’—signals that the speaker should keep going. Because ‘mm-hmm’ is made with a closed mouth, it’s clear that the signaler does not intend to speak.”

Huh? The valuable role of interjections
Utterances like um, wow and mm-hmm aren’t garbage — they keep conversations flowing

This tracks (lol) and seems obvious, but the data is fun. “Younger listeners tend to exhibit a ‘discovery mindset,’ actively seeking novelty. Older listeners may approach streaming from a ‘maintenance mindset,’ knowing what they want and using a given platform to reinforce established preferences.”

When @andrewliptak.com writes about Lord of the Rings, I pay attention. This is one if his best, y’all. “A critical theme throughout Tolkien’s work is the decline of a once-great people, with weak men failing to live up to the lives and stories of their predecessors.”

Hah! Too real. My wife and I always joke (?) that if we ever get divorced it would be over “irreconcilable differences about music.” Anyway, I mostly ran it through my NAD M33, but also gave it a whirl through the office setup, which is the Simaudio Moon 240i. Both were amazing.

I finally had a chance to make my way through this well-researched Spotify exposé, and dang it’s infuriating. “A model in which the imperative is simply to keep listeners around, whether they’re paying attention or not, distorts our very understanding of music’s purpose.”

Regarding "missed" and "slipped" deadlines
One of the issues with quarterly planning cycles and committing to due dates on that cadence is that teams are often asked to commit to dates before they have figured out all the unknowns.

I think going forward I want to use my Kindle like I use Spotify. Sample a book/album to see if I like it, and then buy it in physical form (or Bandcamp!) if I do. Like when we used to listen to CDs in the record store to decide if it’s worth spending that precious music budget on.

I am trying to read more books in 2025 so I am testing a theory that it’s the Kindle that puts me to sleep as soon as I open it. So here is an actual TBR pile! This year’s non-fiction theme is music. Fiction theme is all SF/F (with the exception of the new Orphan X novel because I love that guy).

A great intro to a great essay about #jazz and what the genre is all about. “In the 1999 film The Talented Mr. Ripley, Dickie Greenleaf, a jazz head living in the 1950s, owns a copy of Miles Davis’ Tutu, which was released in 1986.”
