I remember a story of an Oracle Database customer who had production broken for days until an Oracle support escalation led to identifying the problem as mere "No disk space left".

Where did you get the information that SFO doesn't use TSA?

This is not a problem.

The government _must_ come to every city to collect votes.

Amazing that we were able to build technology that verifies if an account on the internet is a bot or not, but we can't figure out whether an account is a human or not (even by rule of exclusion when we can identify it is a bot!).

What a stupid timeline we are living in...

NPM as a cross platform package distribution system works really well.

The install script checks the OS and Arch, and pulls the right Rust binary.

Then, they get upgrade mechanism out of the box too, and an uninstall mechanism.

NPM has become the de facto standard for installing any software these days, because it is present on every OS.

To not worry about system threads. Just create VTs freely without concerns with memory, pooling, etc.

In many cases, yes, public fields are fine. But there are limitations:

- Can't synchronize access. `synchronized` keyword is not applicable to fields, only to methods and code blocks.

- Can't proxy. Not possible in public fields, therefore can't intercept calls before state is changed. This is useful for example in mocking frameworks, and telemetry libraries.

- Can't evolve. Methods allow encapsulation, which allows evolution of the implementation detail. For code base where the public field is accessible by consumers only within the same code base, this may be fine. But for shared libraries, it can easily become a problem.

To be clear, Records don't have setters. They are immutable.

Re the Python thing, not really. I made that joke because originally yes the HTML generator was written in Python, but I deliberately asked to rewrite in Java.

Hey mate, what UX would you suggest? Happy to explore ideas!

For a better visualization to compare old/new, just click on the card and it will open that particular pattern in a new page.
