This is devastating and deeply saddening news. I thank Stefan for the many insights and conversations. May he rest in peace.

Today we are excited to open the first PR of our exploration into fine-grained reactivity! 🚦 This is the foundation to allow prototyping & amplify the value of an upcoming RFC on our plans to introduce a new reactive primitive into Angular. Read more:

What are custom elements? What do they well? And, most importantly, what do they not do well? @iamjoyheron explains it to you in her latest blog post. 👉

We used to copy designs from Stripe. Now we copy designs from Linear.

How WEIRD is #CHI (again, in 2023)? My #CHI2023 submissions on studies of Chinese platforms often got critiques about generalizability, whether challenged for limited contributions or requested to further discuss this. Were studies conducted in US/EU requested to discuss this?

Simple approach to dealing with existing technical problems: 1. Add observability so that you can understand the problem deeply. 2. Add test coverage so that you can change quickly and safely. 3. Make the change you believe will address the problem. People often jump to step 3.

@TweetwallFX Special shout out to @Martin_NB, @JPeredaDnr, @reinhapa, @JMibu @FlorianNB for their contributions and support.. #devoxx keep the ideas 💡 coming for next year's awesomeness - maybe running on Java 21...

With few exceptions, you should NEVER start generating new ideas in a group - always start with people writing ideas alone and only then move to a group setting. (We've known starting with groups is worse for 50 years, but people still keep doing it since it feels more creative)

Finally got around to writing up an idea I've had in back of my mind for a few months: how do you learn to estimate disk space? IME, it's a particularly useful case of "back of envelope" estimation for architecture discussions, interviews, etc! https://t.co/SNRwB9Rtmc

My husband correctly guessed what caused today's Hacker News failure. He'd experienced it before.

"Text-overflow: ellipsis allows to at least have an indicator that text is missing. But there is no way to make the hidden text visible" —⁦@yatil⁩ This. Also: Don't follow recommendations blindly. Always test for a11y/usability issues. #CSS #a11y

The JVM does not load all classes in the classpath. It only loads the ones it needs. What triggers the JVM to load a particular #Java class? Then answer might surprise you. Consider the code below. What does it print? Let's show the output and explain why. 🧵

✍️ New Article: Learn CSS Subgrid I explained how CSS subgrid works and what the problem it solves, along with a few examples and real-life use-cases. I hope you find it useful! 🔗 https://t.co/N7XsWMs9Fw

Lovely.

If you're running a server with #Log4J, please add the following JVM argument to your command line immediately to protect against a 0-day exploit. -Dlog4j2.formatMsgNoLookups=true https://t.co/MWYhEdnS0r #Java #Security #Infosec

Log4j maintainers have been working sleeplessly on mitigation measures; fixes, docs, CVE, replies to inquiries, etc. Yet nothing is stopping people to bash us, for work we aren't paid for, for a feature we all dislike yet needed to keep due to backward compatibility concerns.

JVM with <5ms GC pauses (ZGC) is quite something. Great article by @kstefanj. Read here: https://t.co/79B1BlSZUs

* A refactoring is a *small* change that preserves the behavior of the system while improving its internal structure. Something you can do in minutes or 10 of mins. * Refactoring is part of the TDD cycle: write test, make it pass, check in, refactor, check in (again, 10s of mins)
