I think it's great because although dominated by Ruby (Griffin is a committer on Rails, and I gather it's ThoughtBot's main language) the discussion is typically applicable to other languages, or focuses on a human element. I don't think I've ever written a line of Ruby, and I enjoy it.
There's also some Haskell discussion and more recently a lot of Rust - Griffin having created the Diesel ORM [2].
The format's great though, and as a consequence never sounds like a contrived dialogue - it typically starts as a "what have you been working on this week", and that recent real experience turns into a more general discussion around whatever it was.
I can't really recommend it enough, I only found it fairly recently, and went back through to listen to the entire catalogue of episodes.
Regular listens - shows to which I subscribe, in rough order of how excited I am to see them show up in my podcast app:
Not So Standard Deviations [0]
Immutable [1]
ShopTalk [2]
Talk Python to Me [3]
The Versioning Show [4]
Data Skeptic [5]
Occasional listens - not subscribed but regularly check for interesting guests:
Data Stories [6]
Partially Derivative [7]
I tried Software Engineering Daily last year and wasn't a big fan - based on the following here I'll have to give it another shot.

NSSD is great tho.
Developer Tea is along the same lines, straddling between technical topics & career development.
Soft Skills Engineering is entirely focused on, well, soft skills.
Leader.team is just getting started but they seem to be a good resource for technical leads & managers.
JavaScript Jabber has great interviews.
and it's not a technical podcast, but Creating Disney Magic (Lessons in Leadership, Management, and Customer Service) with Lee Cockerell is a must-listen for me every week.
- Vimcasts
I have tried several tech-related podcasts, but gave up on most within a couple episodes.
One common format is a host who brings on a new guest for an hour-long interview each episode. My main gripe with these is they're too long for the amount of substance they contain.
I ended up basically scrolling the archives of these shows to pick out only the guests I was already interested in, because the random ones just weren't worth the listening time.
The podcasts I keep coming back to are concise, edited episodes of 30 minutes or less. Most of these aren't directly related to the types you're looking for, though. I'd love to know of more.

Software Engineering Daily
Software Engineering Daily seems to dominate my playlist. I guess that shouldn't be a surprise.Last year, I listened through a lot of the Changelog's back catalog. But I sort of maxxed out on it because my interest is more toward the infrastructure than the front end development tools.
Developer on Fire[1] tends to feature more personal interviews with software developers.
Software Engineering Daily[2] produces episodes at a similar rate to the previous podcast but discussion tends to be product-oriented.
Coder Radio[3] can be good fun sometimes. The hosts can sometimes be a bit over the top.

My favorite podcast because the hosts (a) are highly talented developers (b) did careful research for each episode (c) chose common Apple programming challenges as the topic for each episode.
Sadly, it died last year, and I've found nothing out there to fill its void.
Edit: funny replaced with off topic
