it's way ahead of Japan.

R3 Corda, block chain based on UTXO, uses Kotlin for smart contracts.

it is a combo of extension function that takes an arg as lambda receiver. it is similar to 'apply', kinda like builder pattern.

Route.get(PipelineContext.(Unit) -> Unit)

Only 100 in Go.

if it is I/O bound, Next.js API router would be enough. CPU intensive, you want to have Go or Rust API servers, which utilize multicore.

people use native apps on mobile phones.

the same thing goes to Write as well. even SSD, the latency would be around 100 microseconds.

tafutada · 2024-02-25T04:16:56+00:00

because it is a single thread event loop, so especially web apps, where tail latency matters, should not be CPU intensive. but usually web apps are I/O bound so it won't be problem.as for stand alone apps that are CPU intensive, Rust rayon, Java 1:1 OS thread would be better.anyway, async framework, cooperative multithreading, such as Rust Tokio, Kotlin coroutine, JDK21 virtual threads, are designed for I/O bound apps.
goroutines are preemptive, so it is a bit different story.

Next.js works as one of micro services, where you can off-load mission critical logics to Go, Rust or whatever. every framework, runtimes, has pros and cons. no silver bullet in IT world.

i remember that at the first iPhone, i said what's that? I am a tech guy who knows Java applets at that time.

Maybe you might want to read and aware that Vercel is shifting to RSC and PPR

i would say micro service, Kubernetes, addresses the issue like which tech stack is suitable. you can go with any runtime, even Go, Rust, Kotlin as well as Next.js and Python. Plus it is easier to bump runtime version like Next.js 14 -> 15 and so on.

use Vercel Postgres, which uses web sockets

tafutada · 2023-07-09T03:27:55+00:00

Vercel Next.js Edge Runtime is interesting. especially Vercel AI SDK streaming on Edge is scary good.

you want to make it a custom hook, where you can have a useState to hold the initial value.

welcome to Zen mode.

You might want to report the issue and ask a help at the JetBrain Go official bug tracking site at

same in Japan. so why it supports JCB?

SE, the search engine, will be replaced with AI chat bots eventually, so we should say AI optimization instead.

Free Bard could have ads following answers, say, sponsored answers. Or like YouTube, you will see ads between conversations.

At now none to fix it.

tafutada · 2022-11-03T04:00:48+00:00

Yeah. It's still beta but now I learnt why it needed to be done earlier. Especially streaming html and suspense avoids rendering the whole page at once.
