Reflecting on what the fact I can say "Where is smoked salmon please?" in more languages than I can ask where the bathroom is says about my priorities.

Me at my most European: I will be off work hiking for the next few weeks.

Me at my most American: …but if it’s really urgent here’s how to get in touch via Iridium satellite.

How I send up on side quests:

Time to take a shower
But first I should work out
But I should watch that informative video while I work out
But if I use my laptop for the video, I might as well finish the code change I was making last night

Which is why I'm doing a large refactor before my shower.

I love the water reflections.

The nice thing about living rurally is I can run down the street screaming to get out stress and no one cares.

Achievement Unlocked: I used a chainsaw for the first time and the only limbs I cut off were on a tree!

Bonus: It was even the correct tree!

Spending my Sunday diving into GDPR rules to make sure an app I'm about to release for free for others complies.

It turns out when I have no plans to monetize the app at all and have essentially no metrics besides "app crashed" it makes it much easier to be compliant :).

A chess edit where it's a war painting but chess pieces are photoshopped on top of the soldiers. The king says "u did great in the fight so I'll promote u." The pawn goes "really I'm gonna be a general?!" The king replies "no....my wife."

It's simultaneously surprising and unsurprising how much safety and trust impact productivity.

Being able to seem calm while totally panicking is perhaps one of the most useful skills.

This is interesting as a companion to classic build artifact caches for large scale build systems. I do wonder if instead of wanting the exact same source we'll go to API compatible 'module' specs, and the build cache guarantees conformance and performance of a certain level.

Turning up at sniper training school and announcing that I put my AirPods on the wireless charger correctly first time every time and graduating immediately.

A meme, text label of "born too late for AI:" with an illustration of an early perceptron network, text label below of "born too early for AI:" featuring pictures of Neuromancer and Altered Carbon book covers about high tech AI futures, text label below of "born just in time for AI:" with a gemini-cli instance in my terminal

This AI template is evergreen btw, a few years ago I would have had deep learning instead.

Today I am thinking on the ephemeral nature of all wonderful experiences, and how that is one of the things about them that makes them so incredibly impactful.

The best of these experiences leave a mark though, be it a love bite or just a faint taste, something you can hide in, even in hard times.

For me, my anxiety is 99% of the time the least helpful thing - it almost always holds me back from doing things that are positive and impactful when I eventually do them.

...that 1% of the time where it saves me makes it hard for me to entirely write off.

I understand expected value, but still.

Today I forgot how old I was - somehow the fact that I am actually younger than I thought only makes me feel older

Especially if you make sure the theme system is setup well it’s easy to just give some colors and fonts yeah :)

I don't know why, but I feel compelled to add theme support to any personal project I'm making.

Even CLI stuff.

I'm sure not universal, but many ADHD friends and colleagues say they feel the same way. Ironically, we're all manually writing more code due to constant stimulus feeling good - it's just critical/hard code more.

It's like I have a button that triggers my hyper focus now. It's wild.

Experiences with agentic flows as someone with ADHD:

* Constant stimulus from monitoring agents is good for me
* Feels like incident command
* Easier to write code manually too while I have agents do the easy stuff and review it
* The code I am writing is _better_
* I don't get cognitive burnout

ssh is an obscure but widely-deployed command. It stands for Secure Snake Home and was made in the 90s to securely play snake online

I made a massively multiplayer backend for it with support for thousands of concurrent snake players

ssh snakes.run to join!

So glad we finally have drafts here. My brain has so many ideas and keeping them in a separate app has not been cutting it for me.

I kept waking up to check my notes app and was like “well this is funny but why is it here? Delete.”

One of the hardest lessons I've ever had to learn was how finite my time is, and how to focus on everything is to focus on nothing.

Apple Codesigning In Depth: Part II The second of a multi-part series covering Apple codesigning in depth. This post covers odd corner cases with code signing, how to interrogate a code signature, and how to debug signing issues.

Finished my second article on Apple code signing, digging into corner cases and how to investigate failures for both iOS and macOS bundles. Benefit from my many years of misery!
kayla.is/posts/codesi...

In Part III I'll discuss supply chain security considerations and code signing in large infra.

Slick UI would help but totally agree even if it’s a bit confusing it’ll be less so than anything else.

LLMs keep getting better at coding, we have to get better at determining where it’s more and less safe to apply them.

I saw someone vibe code a personal project that used a crypto library and accidentally create a side channel exploit.

I worry it’ll take high profile mistakes for us to learn.
