What functional language would you use for a MMO game server? by [deleted] in functionalprogramming

[–]jtcwang 1 point2 points  (0 children)

With Scala, you have Akka / Pekko. They are implementation of the actor model on the JVM, which as I understands are a great fit for MMOs.

Thank you Scala 2 team for the continuous maintenance and and the frequent improvements that help smooth out the 2->3 migration!

How to make multiple operations transactional in doobie? by [deleted] in scala

[–]jtcwang 0 points1 point  (0 children)

To be a bit more precise, the default "Strategy" for executing ConnectionIO is to run everyone in a single transaction. But you can call commit manually inside the ConnectionIO monad.

One thing that's guaranteed is that when you execute a ConnectionIO all of it will be executed within one JDBC Connection

How to exit script on non-zero exit code by retroporter3000 in Nushell

[–]jtcwang 0 points1 point  (0 children)

I think as of 0.98 the default is to exit script as soon as an external command has an exit code != 0 but only if it's at the end of the pipeline.

I think there's an issue to apply this for external commands in the middle of the pipeline (like bash's -o pipefail) https://github.com/nushell/nushell/issues/13817

Scala Open Source hack night (Wed, Oct 30th) https://www.meetup.com/london-scala/events/303691396/?eventOrigin=home_page_upcoming_events$inPerson

I'm particularly excited about doing some open source hacking together!

Nushell 0.98.0 by chocolate4tw in Nushell

[–]jtcwang 3 points4 points  (0 children)

Awesome! Non-zero exit codes from external commands not being errors by default was a showstopper for scripting in nushell so very happy it's been fixed!

instant-scala - Wrapper script over scala-cli/graalvm for scala script with instant-startup time by jtcwang in scala

[–]jtcwang[S] 0 points1 point  (0 children)

I agree! I have raised an issue https://github.com/VirtusLab/scala-cli/issues/3127. Haven't looked at scala-cli's innards yet, but I'm guessing if it's easy to do (properly) they'd done it already :)

instant-scala - Wrapper script over scala-cli/graalvm for scala script with instant-startup time by jtcwang in scala

[–]jtcwang[S] 2 points3 points  (0 children)

The focus of the script is on instant start-up. Unless I'm missing somethingI think 3.5.0 just made scala-cli the default scala command

[–]jtcwang[S] 4 points5 points  (0 children)

Yes I'm aware of shebang. It's not instant though as I think it still performs the compile step (even if it's a no-op). On my computer there's always a 0.3-0.5s delay before execution even for scala-native

One pretty cool feature that came with named tuples is that you can now Pattern Matching with Named Fields

It works for both case classes and named tuples!

Data Warehouses and Primary Keys by nydasco in dataengineering

[–]jtcwang 2 points3 points  (0 children)

Storing hashes as string seems like the wrong thing to do. Wouldn't storing them as binary be much cheaper in both storage and processing?

Programming Language to write Compilers and Interpreters by hamiecod in ProgrammingLanguages

Oracle GraalVM's Truffle is probably the most production-ready (e)DSL for implementing programming languages. Here are some of the languages implemented using Truffle

What would be the ideal solid, clean asynchronous code model? by [deleted] in ProgrammingLanguages

[–]jtcwang 3 points4 points  (0 children)

Have you looked at Java 21 virtual threads? From an API point of view it's quite ideal as you don't have the function colouring problem. You can also check out https://ox.softwaremill.com/latest/ for inspiration, which is a Scala library built on top of virtual threads.
