    mal - Make a Lisp

    Project mention: Ask HN: Is Lisp Simple? | news.ycombinator.com | 2023-08-21

    >Would be interesting to see how the interpreter works actually...

    It's quite easy to see, there are interpeters for Lisp in like 20 lines or so.

    Here's a good one:

    (It has the full code in a link towards the bottom)

  • Finagle

    A fault tolerant, protocol-agnostic RPC system

    Project mention: Features of Project Loom incorporated in Java 21 | news.ycombinator.com | 2023-08-15

    Not sure about now but a few years back the company I worked for was heavily vested in Finagle [1] using Future pools. I'm sure virtual threads would only enhance this framework. Also, Spring and it's reactive webflux would probably benefit as well [2].

  • Zeppelin

  • Gatling

    Modern Load Testing as Code

    Project mention: Best Practices in Testing GraphQL APIs | dev.to | 2023-07-03

    Performance and load testing are essential parts of GraphQL API testing. It ensures APIs can handle expected traffic volumes and respond within acceptable timeframes. You can use tools like Apache JMeter or Gatling to generate realistic loads and evaluate the API's performance under different scenarios. Techniques like batched queries and caching can help mitigate this issue.

  • sbt

    sbt, the interactive build tool

    Project mention: Declarative Gradle is a cool thing I am afraid of: Maven strikes back | dev.to | 2023-11-11

    NOTE: I won’t mention SBT and Leiningen here because, with all due respect, they are niche build tools. I also won’t discuss Kobalt for the same reason (besides, it’s no longer actively maintained). Additionally, I won’t touch upon Bazel and Buck in this context, mainly because I’m not very familiar with them. If you have insights or comments about these tools, please feel free to share them in the comments 👇

  • Scalaz

    Principled Functional Programming in Scala

    Project mention: Going into year 2 of Software Development Foundation Degree, have a particular liking for OOP and SQL, any tips, info or pointers on where to go from there? | /r/cscareerquestions | 2023-05-29

    I'm sorry, but have you ever done functional programming for a real company, like in a functional programming language like Haskell, Scala, or F#? Have you ever used Scala cats or scalaz? Have you ever learned category theory and how to apply its abstractions in software? Listen u/judethedude2106 this person hasn't gone as far down the functional programming rabbit hole as I have. Beyond learning the basics like the difference between pure and impure functions, what are closures, what higher order functions are and the most common ones like .map, .filter, and .flatmap, the immutable collections like immutable linked lists and trees, and what a Monad is and common monads like those used for futures/promises, async programming, and Option (Some or None, which is used instead of null checking), the more advanced functional programming stuff like category theory based abstractions are totally useless for real jobs and is just a giant time suck. Don't waste years on functional programming, spend at most a few months on it and no more.
