    Project mention: How to use Spark and Pandas to prepare big data | | 2022-05-10

    Apache Spark is one of the most actively developed open-source projects in big data. The following code examples require that you have Spark set up and can execute Python code using the PySpark library. The examples also require that you have your data in Amazon S3 (Simple Storage Service). All this is set up on AWS EMR (Elastic MapReduce).

  • kafka-manager

    CMAK is a tool for managing Apache Kafka clusters

    Project mention: Any advice on setting up or working with Kafka? | | 2022-02-18

    Some random tips: * Use SSDs, not magnetic disks. Our Kafka brokers used to use magnetic disks for more throughput, but this caused wayyyy more problems, like very slow broker restarts. * You'll want to install something like Burrow so you can get better lag metrics. * You might want to install CMAK. It's a web interface for common ops tasks.

  • mal

    mal - Make a Lisp

    Project mention: Roll a Lisp in C – Evaluation | | 2022-05-07

    > Quasiquoting means creating a list where some elements are evaluated at runtime

    Take a look at the awesome 'Make A Lisp' (MAL), in particular the section on quoting:

    This has a fairly good description of what happens during quasi-quoting.

  • Gatling

    Modern Load Testing as Code

    Project mention: Discover issues with performance testing | | 2022-05-16

    There are many tools out there like Gatling, Locust, and K6, but here I'll explain just a bit of JMeter. It is totally visual and pretty easy to follow and understand 🤗; it also includes a module that generates dashboards that gives us an APDEX result, which is what we want. By default, I have it on my system; you can use the same idea or simply download it from the official website and run it afterward.

  • dotty

  • Scala.js

    Scala.js, the Scala to JavaScript compiler

    Project mention: Scala 3.1.2 released! | | 2022-04-26

    How does all that affects the average Scala developer? Well, there's a broad spectrum of users ranging from the ones "enjoying a simple and comfy typed-python" to the "fleet of PhDs and postdocs at EPFL" making you feel ridiculous about your theoretical baggage, and a damn vibrant community of enthusiasts in-between, trying to catch-up with the flow and becoming better every day by doing so. Scala is perhaps one of the best languages out there if what you are doing is a work of art/love or if you work in a problem space where the unique capabilities and abstractions of the language makes it a no-brainer. It also has some impressive cross-compilation abilities (to javascript or to native) making it extremely versatile.

  • polynote

    A better notebook for Scala (and more)

    Project mention: Scala and WebAssembly? | | 2021-10-19

  • Scala Native

    Your favorite language gets closer to bare metal.

    Project mention: What is Scala Native use case? | | 2022-01-23

    Until recently, there was only 64-bit support. 32-bit support is coming, though, see this pr. This means that you will be able to target 32-bit microcontrollers soon. Anything lower than 32-bit might not be realistic.
