Project update

In June, when I started the jolt-jni open-source software project, I considered it a subsidiary project. However, it proved so absorbing that it soon soaked up most of my attention, leaving little for all my other projects.

This is surprising, since unlike most of my projects, it has no graphical component (yet) meaning no satisfying CGI images to enjoy (and perhaps share on social media).

Also unlike most of my projects, I was coding it from scratch, yet constrained by a preexisting API. In practice, that meant writing a ton of boring boilerplate. Prior to this I'd been scornful of the idea of using AI to generate code. But for generating boilerplate code, I can see that mechanical aids have their place.

Now that the library is about 80% complete, I've turned more of my attention to testing. My progress (measured in lines of code) is much slower. Some days I delete more code than I add. The good news is, I enjoy troubleshooting far more than coding.

For the record, here are the current statistics:

+ 1472 commits

+ Overall 48K lines of code (excluding comments and blanks)

+ 29K lines of Java (including 8K lines of tests and examples)

+ 17K lines of C++

Logging Frameworks that can communicate directly with Fluent Bit

While the typical norm is for applications to write their logs to file or to stdout (console), this isn’t the most efficient way to handle logs (particularly given I/O performance for the storage devices). Many logging frameworks have addressed this by providing more direct outputs to commonly used services such as ElasticSearch and OpenSearch. This is fine, but the only downside is that there is…

new coding challenge

Software coding is a highly creative pursuit. But for the past few years, I've put most of my software effort into maintenance and troubleshooting. I've written *some* new code, of course, but a lot of that was for demos and tests. I'd begun thinking of myself as primarily a maintainer, not an innovator.

For the past 6 weeks, however, I've focused on writing a new open-source library from scratch. So far, it's 7,000 lines of Java and 5,000 lines of C++ (excluding blank lines and comments).

Sustaining 250+ lines per day is possible only because a lot of what I'm writing is boilerplate requiring scant creativity. At this point, the design is mostly set. The API is closely based on another project. The biggest challenge has been boredom.

That's why on 11 July (when Gradle v8.9 was released) I pounced on the opportunity to upgrade all my projects, even though it was boring, routine maintenance. At least it was a different flavor of boring.

I look forward to finishing this phase of the project and getting back to maintenance and troubleshooting.
