The HTML workshop at the Harold Washington Library was a success! It was an absolute joy to see people's faces light up when they realized they had published a website in 2 hours.

One of the hardest problems to solve with concurrency is catching nondeterministic bugs.
I've created a must-read deep dive for my paying patrons that provides a robust pattern on "Unit Testing Concurrency + Caching".

![[Deep Dive] Unit Testing Java Concurrency + Caching
This pattern is ideal for stress-testing shared state or synchronization logic. It helps catch non-deterministic bugs (e.g., race conditions](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:j35lllc4rqjaisq4zdhqrwd6/bafkreid3xblp67vdqhhxa2l5wnvksyor2ncqkey7dfuowi3dpp7pvgtrea@jpeg)

This week on Patreon, I talk about mocking in a notecard.
If you're doing more than 2-3 mocks in a test, it's well worth taking a pause and rechecking what you're doing. www.patreon.com/posts/131556...

I'll be speaking at Droidcon NYC June 25-26 on Kotlin Coroutine Mechanisms (part 2!)
The talk is also a sneak peek of the upcoming Droidcon Academy eBook release, "Mastering Kotlin Coroutines: From Basics to Advanced".
I'll drop a few easter eggs as the date gets closer 🤠 #dcnyc25 #android

I'm getting excited about how this Droidcon Coroutines Codelab is turning out. Here's one topic I'm writing about:
Channel.Rendezvous is the default setting for Channels. Channel.Rendezvous creates a 0 buffer channel. Data can be sent through channels when both producer + consumer are ready.

hemingway.app is my favorite writing app I use. I tend to get verbose with complex thoughts, so I try to aim for a grade level of 9 whenever I'm writing articles or books.

![online editor with text pasted in. In it reads [T] There's a lot of logging here, and strange logging at that. Here, important observations are to be made. For example, we are indeed updating values out of order in the child coroutine, but the value of the mutable list is not being updated in time in the parent coroutine. Hence, no shoppers are printed for any of the "curr order in parent: []" lines!
[T] What's more, if we run the code again, it's possible for the ordering of execution to change:
[Code: bash]
curr order in parent : [] | current thread: main @coroutine#1
curr order in parent : [] | current thread: main @coroutine#1
curr order in parent : [] | current thread: main @coroutine#1
curr order in parent : [] | current thread: main @coroutine#1
Final order: []
curr order in child launch: [Jake] | current thread: DefaultDispatcher-worker-2 @coroutine#2
curr order in child launch: [Jake, REE, Zubin, Amber] | current thread: DefaultDispatcher-worker-3 @coroutine#4
curr order in child launch: [Jake, REE, Zubin] | current thread: DefaultDispatcher-worker-1 @coroutine#3
curr order in child launch: [Jake, REE] | current thread: DefaultDispatcher-worker-4 @coroutine#5
[T] By design, coroutines do not execute sequentially. Rather, they decide what should run fastest, which often overlap coroutine work across threads. As we learned, the state of the orderOfCheckout is not the same between child and parent jobs."](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:j35lllc4rqjaisq4zdhqrwd6/bafkreifyekypwbzd2mqaysqc37i5c2dptma3x76zjo23sd7wraxm4agp6a@jpeg)
