#Tokyo

An amazing #city

The largest city in the world

...Not anymore

"With an estimated population of nearly 42 million residents, #Indonesia's capital #Jakarta soared from 33rd place to surpass #Japan's Tokyo, according to a new #UnitedNations report"

A mind boggling fact for you:

The population of #Java is about 155 million

The population of #Russia is about 145 million

Java is about 2/3 the size of #GreatBritain!

That's what rich volcanic soil does

Hi #Java friends! 👋

What tools do you use to visualize dependencies between your sources (package-level) in your project? 🤔

Thanks for any hints! 😊

My online talk on Tuesday, Nov 25 at 6pm UTC is my #Java based "Event-Sourcing from Scratch" talk. Details and _free_ registration at https://luma.com/dt9fc391

Event Sourcing is the storing of state-changing decisions made within a part of the domain.

#rust I now have code that gives me a list with 24 time zones, one for each full-hour offset from UTC. It's not nice, but my #Java version wasn't nice either (https://codeberg.org/dtanzer/tzsh/src/branch/main/java).

I'll push the rust version when at least a few things work.

On Tuesday, Nov 25 at 18:00 UTC, I'll be doing a 90-min online presentation of my #Java based "Event-Sourcing from Scratch" talk. Details and _free_ registration at https://luma.com/dt9fc391

#DevNexus is one of the top community #Java and Cloud conferences, so come and see me and other great speakers present all the Cool and Useful ideas and techniques. Use the code SEEMESPEAK to get an extra $100 off the registration at https://devnexus.com/

Refactoring Needs Empathy (h/t Andrea Goulet), but it also needs Skills.

At #DevNexus in March, I'll be showing my favorite techniques for #Refactoring in #Java using IntelliJ IDEA. Even if you're an experienced coder, I'll bet you'll still learn a few new things to try out...

Another implementation of game-of-life, this time in #Java and I tried to use some #functional constraints:

https://codeberg.org/dtanzer/game-of-life/src/branch/main/java-func-constraint

Didn't clean up the test file, that was not what I wanted to practice this time. Also, forgot to commit after each micro step during the #TDD cycle.

And it's probably my last game-of-life for some time, since this year's global-day-of-code-retreat is over. #gdcr

Thank you to everyone that attended our talk on writing #AI models in pure #Java 🥳 !!!

I realized in talking about #Java in another thread that one of the things about it that I find most frustrating as a "regular user" is that Java applications don't act like other applications on the command line.

With some languages like Python, Perl, Ruby, Lua, most Lisps, and Elixir, you can run a command on the source directly, ala

perl foo.pl

Or compiled languages like C, C++, Go, or Rust, I can run the compiled code:

./a.out

But with Java, I have to essentially do both, since I have to invoke the JVM on the compiled object.

My position was eliminated as well. If anybody needs a software engineer, I'm looking for my next role.

My last position involved C, maintaining a legacy codebase supporting cyber operations. Multi-architecture experience.

Proficient in C, Swift, Rust, Python, Java, and familiarity with many other languages.

On today's live coding (yes! I'm back streaming on https://jitterted.stream!), I was surprised to get a ClassCastException while iterating over a List<CustomerEvent>! From what I saw, toList() uses toArray() which may cause type info to be discarded.

More details soon...
