I think the questions no. 1, 2, 3, 8 are likely to show up, the rest not so much. As a junior I think your most important skill will be the ability to learn (it still is the most important skill later on, but experience will overpower it on interviews) :)

It took me a sec to understand what you meant by "freshers", at first I thought it was a programming term 😂 because you mentioned scopes. I would expect some basic knowledge of the language and standard library, i.e. you can write a simple command-line app without messing with frameworks. Although knowledge of a HTTP client/server framework would be a significant plus. I can recommend the Scala toolkit for playing with those: docs.scala-lang.org/toolkit/introduction.html

@@kubukoz_ Hey 👋 thanks for your time and the guidance. I will also take a look at the Scala toolkit link you provided. 💯

You don't need to put it in the same file. I think you may be bumping into a bug in the Smithy LSP that prevents new files from being properly registered - try reloading the window / restarting vscode and see if it helps. If it doesn't, feel free to report what you're seeing in github.com/smithy-lang/smithy-language-server/ :)

@@kubukoz_ yeah it was mostly fake errors from the linting. The linter just doesn't work properly, especially with monorepos. Also the one for intelliJ doesn't work at all as it's not yet adapted to the smithy-build.json and expects gradle build.

I'm not sure what you mean with three dots, the completions in this video are 100% powered by Metals, Scala's language server (and its vscode plugin). In other videos I use GitHub Copilot as well, it's an ML-based tool

My quick guess is that it's because Ordering also has methods like def max(x: T, y: T): T - there's a T in the covariant position.

I just checked, and there's no problem with such a definition. So, I don't know why they didn't do it 😅 But also, I remember in the past there were some issue with co/contra-variant typeclasses in Scala. gist.github.com/kubukoz/70f74407a078b96fe177168acfa16d7e

I don't 😭😭😭 on a real note, I'd love to make something about this topic, but it's pretty ambitious and I don't have the capacity at the moment.

I had to apply some pretty aggressive noise reduction, or else you'd mostly hear fans :/ I wasn't prepared for this amount of noise to filter 😅 still better than my voice quality on some of the older videos.

Completely audible IMHO

episode 12 was published long ago, that's the end ;) ua-cam.com/video/erzlLMnf_8s/v-deo.html

Are you using the extension from disneystreaming? It should be able to download Coursier by itself (right now it looks like there's no such program). What OS are you on?

I work on a team that (among others) builds Smithy tooling for our org, so we deal with Smithy validators regularly (as a user, knowing how they get loaded can also be useful for troubleshooting IDE setup or whatnot). I imagine you could use SPI to e.g. allow users of an educational website to upload additional exercise packs, but there are non-negligible security concerns in allowing arbitrary byte code to be uploaded for execution. Still, for desktop/CLI apps, plugins distributed by trusted authorities this might be suitable (let's say you're Adobe and some of your partners provide plugins for your app). Scala compiler plugins work in a similar way, although it's not actually SPI - there's an xml/properties file (Scala 2/Scala 3) at a standard location with the FQN of the plugin class.

The amount of effects is balanced. So I like it a lot.

1) Given how you started I was expecting a sponsor ad at the beginning 2) I like the xckd quote 3) Now that the screen size gets reduced when you say unpopular stuff, u'r a real UA-camr

@@TonioGela89 ...but before we get to that part, a word from our sponsor, VMWare...

Like, about building a codegen? Not sure, but there will be some stuff that'd be useful for that as well (programmatic access to the model)

@@kubukoz_ Programmatic access would be quite helpful to me personally. I am interested in customizing and creating code generators currently.

For now I can only point you to the docs: smithy.io/2.0/guides/using-code-generation/index.html As for working with the model, I think the API is pretty self-descriptive in most areas. If you're not implementing a smithy-build plugin but want to load a model yourself, this can be a hurdle, and I can recommend looking at smithy-playground, smithy4s's, or the LSP's implementations: github.com/kubukoz/smithy-playground/blob/cb186f4b0b3b46ab0a47409d85537c92d4a8fe7f/modules/lsp/src/main/scala/playground/lsp/ModelLoader.scala github.com/disneystreaming/smithy4s/blob/d7afe2123095bc03389dc30c0a151bff78983ceb/modules/codegen/src/smithy4s/codegen/internals/ModelLoader.scala github.com/smithy-lang/smithy-language-server/blob/6ce7064a88be58df5fb7ebcf35e165f7fae1286f/src/main/java/software/amazon/smithy/lsp/SmithyInterface.java#L58 that said, if you can "plug into" smithy cli / gradle plugin's own build system, that's probably the easiest way to get going.

@@kubukoz_ Thanks. This is incredibly helpful as I am new to Smithy, its API and lib authoring itself. I will try both approaches from above. Overall I just need my CLI tools/options to work with Smithy IDL code as an input. ts-morph & AST libs from unifiedjs do most of the heavy lifting currently.

Usually this kind of thing appears to be done outside of the smithy spec, e.g. in the configuration of whatever client/server you use underneath. For example, in http4s you'd customize your Ember server's settings before launching the server.

I try to remember that but it doesn't always work out 🥺

It's one of these topics that I'm a bit reluctant to touch anymore. I gave some talks about these back in the day, here's the latest version of the talk where I described those: ua-cam.com/video/HMs_F7LXTak/v-deo.html

and there's a full list of my past talks if you want to have a look: blog.kubukoz.com/talks/

No amount of convincing will make scrum masters accept reality, or make reality accept them ;)

yeah, I learned that lesson from the other comments back when this video was fresh 😅 sorry about that, I promise the other videos don't have this problem. I guess this is the Effect (wink wink) of me wanting to flex a new camera back then ;)

@@kubukoz_ Good to hear :) Not that you're a bad looking dude but I'm here to learn

hahah, indeed, this is a learning space 😅

These days the only import is `cats.syntax.all.*` - if your IDE is still having trouble, you may need to check if there were errors when importing the build.

Thank you for the coffee! I appreciate the suggestion, but I don't want to deal with crypto, so I'll probably just skip that one cup 😅 Glad you found this helpful! Just out of curiosity, did you watch the previous episodes or did you bump into this one because of some Tapir issues specifically?

@@kubukoz_ I watched your other videos, but tbh, this was the first stream I have seen. And yes, I was dealing with the Tapir stream api 😀

I'm glad you see it that way! That said, there are many fantastic educators out there who are far better at it 😅

To this day, I still try to curb my perfectionism 😭

I'll keep this in mind for the next video like this :)

It achieves promotions, pay rises and sometimes even a change in the level of responsibility you feel :) Levels are useful. They are hardly consistent though, and one company's senior will be another's staff engineer.

It's not the VM or OS at runtime. The Scala compiler is responsible for tail call elimination.

That was the plan!

That's a good point, I haven't thought of that. Frankly I think too many devs bother about AnyVal wrapping or not (for most of them it'll never become a bottleneck!) but it may be the right thing to use when you want to inherit from traits.

Perhaps I did. It's a pretty old cut from a longer video ;)

This one, I think: ua-cam.com/video/Ig2rY0hR6JI/v-deo.htmlsi=3czUL5XRvLSsd62O

That's absolutely valid, they weren't prepared upfront 😅

I appreciate your feedback and I can see how it may seem misleading. That said, both the first minute and the description clearly explain what's happening so I don't think it's wrong. Yes, it's clickbait, but it's not a lie either (the job doesn't exist, meaning it's fake), and it's clarified early. This is the level of bait I'm currently OK with, and I've seen much worse :)

@tompoczos8312 Glad I'm not alone on this. While I would like to see more high-value Scala content like this on UA-cam, I dislike tabloid-style clickbait like this title. Even if it's not a lie, even if it's not as bad as others, and even taking into account I'm not a native English speaker, the usage of "fake" feels sensational and disingenuous to me. Scala videos are already scarce on UA-cam so I'm not sure these even need clickbait titles.
