    Project mention: Dozens of malicious PyPI packages discovered targeting developers | | 2022-11-02

    Yeah, that's quite interesting reading from them, some sort of specialized appliance really.

    I'm and the average Joe around me, totally far from Netflix's task of packing bytes from disk to network. Simple 2vCPU VPS serving 4GBit without being saturated on system resource level is quite often much more than enough. Extra note - it's not even using kTLS.

    Moreover, even for Netflix, noting they know FreeBSD in and out, do you think/have info on using FreeBSD as base OS beyond distribution level - running applications/services in particular?

    I've quickly checked on their repos like and it smells like they use containers/Docker, which doesn't work on FreeBSD => I'm in very much doubts it's OS of choice for them.

  • Armeria

    Your go-to microservice framework for any situation, from the creator of Netty et al. You can build any type of microservice leveraging your favorite technologies, including gRPC, Thrift, Kotlin, Retrofit, Reactive Streams, Spring Boot and Dropwizard.

    Project mention: Best library for messenger backend (JVM) | | 2022-10-05

    Armeria ( is a very underrated framework and does not get enough love, it works fabulously with Kotlin (coroutines support also built-in) and integrates nicely with GRPC, Thrift, etc. The maintainers are very responsive and nice and always helping people out.

    Project mention: How to Boost Code Coverage with Functional Testing | | 2022-11-01

    Yes I agree, mocking is a bit of an overloaded term, and the libraries we used for stubbing like gRPC Mock and WireMock also have `mock` in their name, even though they are real servers with stubbing

    Project mention: Hot reload SSL configuration for a server and http client | | 2022-06-12

    Hi, I have been working on a small library to make hot reloading of a ssl configuration for a server and http client possible. I was just curious why we needed to restart the server or recreate a http client with new ssl configuration when the keystores needed to be updated. I wanted to learn how the ssl configuration is handled in java and was just curious if I could be able to bypass this limitation and reload the ssl configuration instantly. An alternative would be to use nginx as a proxy with ssl configuration for a server setup, but I was a bit bored and wanted to achieve this just in java. In the above demo I demonstrate a spring boot with embedded jetty server, however similar behaviour is possible with akka or other servers which use SSLContext, SSLSocketFactory, SSLEngine, TrustManager or KeyManager. The server has an initial ssl configuration and it will get updated by an admin application from the terminal through an https request, but it can also use a file listener to update it. If the keystores on the filesystem get replaced or updated it can also pick that up or fetch it from a database based on a trigger or something else. The demo can be found here I use my own library to have this setup working, which is available here:
