    The hardest part of being an "experienced" programmer is not learning about new languages, libraries, and platforms. It's learning that not everyone around you has 25+ years of development experience and trying to find common ground with them.

    The more time I spend writing Serverless functions the more I understand why the container image is overkill.

    Guy walks into a craft beer bar. Asks what beer is closest to a Busch Lite. There is no punchline.

    I just woke from a dream where I dropped myself six stories onto concrete and "luckily" just shattered both ankles. It was a lucid dream...I could feel the freefall and the shock of landing. Peculiar sensations. And oh my the psychosomatic effects when I woke!

    We are addicted to cloud.

    Replying to @headius
    We rapidly started to afraid to have old good dedicated servers with 64GB of RAM and 3TB of HDD. `What if a hardware issue occurs?`, `How do we backup it?`, `What do you mean I can't change the instance type in a minute?`

    You know, the funny thing about this whole Google bias uproar is that when I read pro-Trump news sources, the news really isn't that much better. They spin things in particular ways, but they seem to have trouble finding good things to say too.

    I wonder if I could pay the neighborhood ice cream man to drive around with my Pokemon Go.

    SPOILERS: jaotc gets normal JRuby startup (full JIT in JRuby and JVM down as fast as "crippled" startup (no JRuby JIT, limited JVM JIT). AppCDS trims about 25% off base startup, 10% off a larger command.

    Yay, --ignore-errors in JDK 11 jaotc command...actually ignores errors. I don't have to carve up my jar to remove dangling dependencies anymore.

    BRB, preparing an extensive blog post about using OpenJDK 11 AppCDS and AOT too improve JRuby startup. Bonus: I'll throw everything I can from OpenJ9 at the startup problem too, and we'll see where we land.

    Anyone tried using Epsilon GC ('s no-op GC for OpenJDK) in a FaaS setting? If you don't create that much garbage, it could be just fine for quick hits.

    Java is having trouble fitting into serverless because Java (EE) *was* "serverless"; deploy functions that call into opaque service APIs and rely on some container to scale and replicate everything. It would be interesting to see a cloud-native Java container that has no edges.

    Say thanks and tell people you appreciate them and what they do for you. Even for the little things. Show them you notice. Don't assume they know how you feel. This works amazingly well, and it's a great way to make others feel good about themselves and about you.

    Howdy! Several of y’all have asked about extending our CFP and since it’s our final time throwing this party we love so much we decide, why not!? We look forward to all your nutty proposals.

    Isn't FaaS just the cloud's way of getting more people to pay rent on the same RAM? It's a freaking RAM timeshare! Where's my Disney tickets?!
