Speaking of Hitchens, I highly recommend his “Letters to a Young Contrarian”. Or any writing of his, to be honest.

The currency codes could probably be inline value classes. That way, you can do val price = 100 money USD Note the lack of quotes around USD.

JetBrains’ Lincheck[0] is a good library in the Kotlin/Java world for this stuff. I especially like that it’s declarative, and also the way it outputs the linearizability results. [0]: https://github.com/JetBrains/

> Scope functions are still huge. I’d put any one of extension methods, value and data classes, immutable variables, structured concurrency, and top-level functions ahead of scope functions for reasons to switch to Kotlin. But hey, if yo

If null-safety on the JVM is important to you, just use Kotlin.

I think the Jetbrains team are dropping the ball when it comes to Kotlin on the JVM. They seem to be focusing their energy on KMP, and I’m not sure they have the capacity to deal with all the platforms they want to target (Kotlin/JS, K

I wonder if that’d make them a broker and not an exchange. Different set of rules, regulations, and licenses.

Interesting read, thanks! Some points: > Hogging instances might pay, if this stops competitors getting good hosts. This would eat into PnL and is also wasteful on energy. Aren’t reserved instances cheaper than spot? > Bad players c

I had a professor who hated Jared Diamond for being reductionist, and I’ve been skeptical of him ever since. However, I see the immense appeal of his theories (and the one linked here) because they’re so simple to understand. They make for

Fair enough, and that totally makes sense. I guess I just miss the “Well, hello friends…” :)

A little off topic: what happened to the hacking videos on YouTube? Used to look forward to them but I haven’t seen a new one in a while.

This is interesting for several reasons. 1. It happened during the Treasury auction, and if the timing was intentional, a case could be made about it being a national security issue. The hackers disrupted the largest, and possibly most impo

Lest someone new to Kotlin only reads the title and decides to spawn bare threads all over the place, don’t. At first pass, it's not clear to me what the actual work the author is doing in his benchmark. Instead, I’d point to the excel

Netflix’s DGS framework for GraphQL is nice to work with but we’ve been frustrated with some prioritization choices by the team. For instance, if you’re using Kotlin, it’s impossible to define and pass scalars to the latest version of the c

I haven’t yet tried KMP, but I think Kotlin in general is slept on here on HN. My experience is on the server side with both Micronaut and Spring Boot and it’s such an ergonomic language to write in. It’s probably my favorite language thus

Yeah, I watched that talk (and many others from KotlinConf) but it was a bit too high level and not actionable.

Can someone please explain how Project Loom and virtual threads in the JVM affect Kotlin’s coroutines?

It’s probably fine, but this sort of thing is why transactionAmount and transactionCurrency are better when separated. Consider the case when you’re doing some reporting from your DB based on currency; do you really want to have to deal wit

I’d also add: — If you’re using JSON to pass around monetary quantities (eg. from the frontend to the backend), put them in strings as opposed to the native number type. You never know what the serializers and deserializers across language

Hi Andreas, when are we getting the next batch of “FIXME Roulette” videos? They’re the most entertaining yet educational debugging videos out there.

One of the updates I was looking forward to, and congrats on the $800k revenue! This year, I hope to transition assembly to China, where all of our parts originate. I’d have thought people were doing the opposite nowadays — bringing
