    Am I against JPMS and microservices?

    I started writing this on my way back home from Devoxx BE 2017. The reason is, two things happened during the conference, that made me ask myself this question.

    First one was a conversation with a very well known person working on Java who was curious to know what benefits I (or perhaps the company I work for) get from publicly speaking against JPMS (a.k.a. JSR376 a.k.a. Jigsaw). The second was a message from a colleague of mine who was asking me to explain how do I feel about microservices because he apparently saw somewhere I’m publicly speaking against them.

    That got me thinking. Is it possible that two of my most popular talks, namely “What’s not new in modular Java?” and “Microservices and modularity or the difference between treatment and cure”, were picturing me as the person who is against JPMS (and therefore Java 9) and against microservices.

    Cleaning up my GitHub mess

    You know how it goes. You continuously stack stuff in the most convenient place (shelf, drawer, desk, …) and it’s all fine, up until the moment you no longer can find what you need. That is the day when you need to put everything else aside and clean up your mess. Not sure if it is Conway’s Law to blame but this seams to happen to my repositories on GitHib. And today was the day when I no longer could recall which repo is under which account, where it resides on my local hard drive and if it’s actually in sync. So today was my GitHub cleanup day. Just in case you need to cleanup yours or if you use one of my projects and something is no longer where you expect it to be, here is what changed.

    What to expect in post-JPMS Java world

    The atmosphere around Java 9 (and most notably JPMS a.k.a. JSR 376 a.k.a. Jigsaw) is getting really hot. Java community seams to be divided into 3 camps “developers who honestly believe JPMS can simplify modularity”, “developers who have been dealing with modularity long enough to clearly see the issues Java platform architects don’t want to see” and “developers who don’t care (for now)”. I personally think the 3rd group is by far the largest and this is the main issue and the main reason for the noise. Why? Because those are the developers who never cared about modularity. Most of them still don’t care, but now they will be forced to learn about modularity. The question is what will they learn? Real modularity as described in Modulariy Maturiy Model or limited version of it wrapped in a package with a label “simple” on it?

    This is not a new thing! The battle between “good quality code” and “simple to write code that works” is something that takes place in every project! And you know which one wins most of the time. At least I think I’ve been in this industry long enough to know, so I though I’ll write down a few prediction based on what I think will happen to JPMS and what impact it will have on Java projects in the following months.

    Getting feedback live

    I have spoken at quite some conferences over the last years. Part of the talks were just me speaking with some (hopefully not too ugly) slides behind me. Some were live demos. Either way, I’m almost never happy with my talks and therefore constantly looking for ways to improve. But in order to improve, first you need to know what your audience like and don’t like. It all comes down to feedback and constructive criticism. Some conferences are quite good at collecting feedback. Polish Confitura is on the top of my list, sending me a document that not only shows how people voted but also all the comments from their online survey. Most conferences though don’t bother to give feedback to speakers. Some don’t ever bother to collect it. It’s therefore been on my mind for a while to try to find a fun and easy way for attendees to provide feedback during (not after) my talk.

    All Those Little Things

    As developer advocate, I do a fair amount of traveling. Most of my journeys start with about an hour long drive to the airport. It’s nice highway, not a big deal, easy to do it without needless stops. Yet I like to make one stop, get myself out of the car for a while, grab a coffee, smoke, …

    One of the first times I drove there, I stopped at some gas station. It was my first time there. As I was getting out of the car, I realized they had a special place for pets, nearby the main entrance. There was bowl of water and another empty one next to it (presumably to be used to put some food in it). There was also a sign, encouraging pet owners to ask for any assistance they may need. I found this interesting, and proceed to the restroom. A somewhat strange hanger on the wall attracted my attention. It turned out to be a dedicated hanger for motorbike helmets.
