@npub1ggt…t0h3 So that's not unexpected and not an error. You either add a `.get` in the end, or insert a `.resource` after `Using`.
It's a tricky API, though.

2024-06-27 20:29:46

- reply

@npub1ggt…t0h3 What you typically want is `Using.resource`

2024-06-27 20:26:52

- reply

@npub1ggt…t0h3 Can you show an example. Could it be, you're using the `apply: Try[T]` version, which returns a `Try` which always swallows all non fatal exceptions until you unpack / `.get` it.

@npub1yy8…yfzq That's a totally isomorphic question.

@npub12jq…hq6m Even with Option could be sometime redundant as null-marker, it's still useful due to it's other monadic properties.

2024-06-25 11:54:03

@npub12jq…hq6m So, while I agree that it (the "explicit nulls") could be a nice addition, I fail to see how Option is it holding back.

@npub1z5w…0u0g I very well understand this situation and I can relate, from experience, in both fields. What may help to whom the IT person is that's struggling here, is to jump into some open source project and help with development or maintenance. Try to reduce the workload on the day job, if that's somehow possible. Open Source is IT work end to end, it may be painful too, sometimes, but it also can be very rewarding.

@npub1ujj…y9sn I guess the value of chat specific to a tool is a different for the maintainer / contributor of the tool comparend to it's users. The user typically seeks for fast help. The maintainer and contributors later search for details, patterns, evidence, when in doubt for bugs, glitches or new features.

@npub1ujj…y9sn Mill main chat room is still on Gitter / Matrix. But it looks like nowadays, you can't read it anymore without a login.
Maybe, we should publish exports of the chat history from the Mill site, like it was done before in the #irc times? Export seems to be possible.

@npub1jfh…78gz Dropping a platform itself is already disruptive. Also, major releases don't need to drop compatibility to previous versions. I guess, it all depends on individual aspects.

Yeah, I have also one in my region:

I wonder, I I should re-map the entrance=main to a entrance=entrance, so that routing from start to the end will not leave the maze.

- reply

@npub1vv9…yuny That was not the point of my message. It's perfectly fine to drop support for older versions, but please, don't do it in a patch release!
Semantically, it's equal to API removal, which needs to be a major release. We can even discuss about a minor release. But not a patch release.

2023-11-24 07:16:01

Dear #Java / #Scala / #Kotlin developers who target the JVM:
Please stop dropping support for older Java Versions in patch releases!
Thanks!

I really like the new-ish Tracestrack Topo style in #OpenStreepMap. Unfortunately, tiles aren't up to date, compared to the default style.

I need to correct myself. I started using #Gentoo in 2002. I just found an old post of mine from 2004, and I think my older me did know it better.

@npub1ze5…vx2k Hah, great! Any package manager comes with it's own merits, I guess. Fun fact: I did only two re-installs in the whole time, one when I couldn't swap the hdd because of IDE vs. SATA, and one to switch over to 64 Bit, which was a lot easier when starting afresh. Everything else was rolling updated, which is a real thing in #Gentoo. I didn't say it's always easy, though.

After being burnt by various binary package incompatibilities on my initial SuSE Linux installations, in 2002 I bootstrapped Linux from Scratch on my first laptop and ran it for two years. That was a really interesting learning experience, but managing wise, it turned out to be tough. After that, I switched to #Gentoo #Linux and never looked back.

2023-10-04 21:54:09

Happy 24th Birthday, Gentoo Linux!
When I started using it in 2004, it was not for performance tuning reasons, but to be able to install exactly the software I want and with exactly the versions I want. All my laptops (ThinkPads) and various servers ran on it since then, which makes me a #Gentoo #Linux user for almost 20 years.

I now tried the Fediverse, created an issue in the Jetbrains YouTrack and also asked in their #Kotlin Discord channel. No response yet. Is there no way or no interest in integrating Kotlin into more tool chains? I'd appreciate any kind of feedback.

2023-09-26 07:29:44

I wonder if every #Kotlin user is really happy with using #Gradle? It's currently to only option to get in the comfort of fast compilation. Outside of this vender-provided ecosystem, compiling #Koltin is really slow. Much slower than my #Scala toolchain.

@npub1xu0…nht3 There are so many reasons why there exist so many different tools. Different requirements, personal preferences, and so on. Creating an uber-tool isn't the right solution IMHO. To the contrary.
But by sharing and re-using the same building blocks in your build-tools, we can improve. To give an example, most build tools don't re-invent the compiler, but if it comes to license management of dependencies, you will find many different solutions or none at all.

2023-09-13 12:31:32

Most #BuildTool plugins should be developed as an library or CLI app first. Then, you can feed everything from your build tool into it. This makes reusing it in other build tools much easier. Also testing is easier that way.
When looking at the current tooling landscape in #Scala or #Java, most tools are exclusive to one build tool. They use the API of that tools and can therefore not easily reused by others.

#Metals 1.0.1 with #Mill BSP is still doing way too much on the Mill repo just to get a reasonable #Scala editing experience. Maybe, our repo is a bit uncommon, as all integration tests and examples end up in separate executable sub-modules, and in some cases (integration tests) lots of modules need to be locally published, but that should not be necessary just to edit the sources. Investigating...

Mill 0.11.2 is out!
https://mill-build.com/mill/Changelog.html#0-11-2
This version greatly improves build speed after build definition changes due a new fine-grained
cache invalidation (change detection on method-level).
We also improved the editing experience and now properly support meta builds via BSP (Metals) and IntelliJ IDEA.
