I took over the Platform Engineering podcast and got to be the one asking questions for a change.

Feels like we covered every aspect of configuration management and I hope y'all enjoy it.

New podcast episode just dropped and this week @kelseyhightower.com flipped the mic and interviewed me!

We went deep on config management, ClickOps, and why the real problem in IaC isn’t Terraform — it’s knowing the right values for prod.

I remember watching Star Wars as a kid and asking myself, who would voluntarily join the dark side? I understood Darth Vader's motivation, but not the stormtrooper's.

Computer scientists like Rich Sutton seem to have a deep respect for nature, and humanity as a whole, which shapes his thinking, and approach to solving computing problems. What you end up with is less hype and something closer to reality.

stty

(from The Secret Rules of the Terminal, out now! wizardzines.com/zines/termin...)

your TTY driver has configuration

you can see how it’s configured by running:

stty -a

for example it print out the current window size!
Ctrl+S

by default, pressing Ctrl+S wi(( freeze your terminal (and Ctrl+Q wi(( unfreeze) I have never wanted this in my life, you can turn it off with stty -ixon (fish turns it off by default)

###fun fact: changing Ctrl+C technically you can use stty to set a different keyboard shortcut for Ctrl+C, (ike “u”

stty intr u

this is extremely chaotic and I can’t imagine a reason that I would ever do this though
programs have to configure the TTY driver to get friendly features

developer: I want arrow keys to work in my program!

other person: better tell the TTY driver to turn off canonical mode! (more on the next page)
the TTY driver’s settings are called “termios settings”

for the gnarly details:

man termios

but if you’re writing a terminal program libraries like readline or ncurses will handle setting up the TTY driver
panel 6

smiling stick figure with short curly hair: I’ve only needed to use stty once in the last 20 years and I mostly don’t understand its output but I think it’s a fun view into terminal internals!

I'm jumping on the livestream with the Flox team to discuss the value Nix brings to the ML ecosystem. Specifically when it comes to managing CUDA dependencies for ML workloads.

Flox @flox.dev · 14d

Don’t miss it!

We’re live with @kelseyhightower.com and @refroni.bsky.social today at 2pm EST to unpack what pre-built CUDA packages in the Flox Catalog mean for teams and workflows.

Our LinkedIn Live is happening this Wednesday!

Following last week’s big news that CUDA packages are now available as pre-built binaries in the Flox Catalog, we’re going live with @kelseyhightower.com and @refroni.bsky.social to dive into what this means for developers and teams.

This is most likely the right answer. At this point people are going to buy stocks no matter what and this game will just continue.

I always love those lists of "35 under 35," but as I get older, I find that I would love to know about innovations/art from people over 65. "65 over 65" please. Elders have incredible ideas that are the result of having seen the full lifecycle of previous ideas and learned from it.

It has to be an internal thing at the various tool companies, and I'm sure it's the reason these models keep getting better.

Do we have metrics on how often LLMs generate similar blocks of code across the industry? Most software being developed isn't unique, and it seems we'd be better served by new frameworks, and higher level abstractions.

But then we're back to the discovery problem, something LLMs seem to help with.

I've been a fan of CockroachDB since its inception. It brought the ideas from Google's Spanner to the masses. That was 10 years ago and in October I'll be speaking at RoachFest 25 sharing my philosophy on building systems that outlast the chaos. www.cockroachlabs.com/roachfest/lo...

Apple made their decision to adopt Zsh as the default shell, and I'm assuming their desire to avoid GPLv3 software means shipping a new version of Bash won't be happening any time soon.
