Using AI when you know a lot about software development is great, as opposed to when you're a newbie (simplistic point, but lots of people need to think about it before declaring "learning to code" obsolete)
I'm not a NodeJS expert, or any backend expert for that matter, but I'm working on a small NodeJS project right now and needed a function to implement exponential backoff.
Now I know what exponential backoff is, though I've never implemented it. I typed in "function exponentialBackoff" and got this function from Copilot
I'm not sure if it is great, but as a developer, I can debug it, reason about it, and improve it. I can own this code and maintain it.
Now imagine doing this without knowing what "exponential backoff" even is - try to explain it to AI. Hell, you might not even realize it exists and can be useful to your use case.
ALT async function exponentialBackOff(cb, max) { let attempts = 0; while (true) { try { return await cb(); } catch (error) { if (attempts >= max) { throw error; } const delay = Math.pow(2, attempts) * 1000; console.error( `Attempt ${attempts 1} failed. Retrying in ${delay}ms...` ); await new Promise(resolve => setTimeout(resolve, delay)); attempts ; } } }

First time running into the RPM limit automating ChatGPT with #PowerShell - seems like my code needs a coffee break as much as I do! #ExponentialBackoff

再帰が必要な場面はどこかって言われるとあんまり多くないけど、とりあえずExponentialBackoffを再帰で書くとかっこいい気持ちにはなれる。

いわゆるExponentialBackoffですね！合わせてJitterも。
その動作をさせるのがデバイス側依存なので、もしかしたらミリ秒単位で間断なく再接続を試行しちゃうデバイスは存在しうるとは思います。
それ以外にも設備間での再送処理もあったりするので更に話はややこしいのです😇

Some days I love Rust, some days I write this type signature: Result<<<F as FutureFactory>::FutureItem as TryFuture>::Ok, <LoggingErrorHandler<ExponentialBackoff> as ErrorHandler<<<F as FutureFactory>::FutureItem as TryFuture>::Error>>::OutError>

前にも同じ流れで書きましたが、待機はどれだけ待てばいいかが確定的に決められないので、よほど特殊なシチュエーションでないと安全に使えないですよねぇ。ExponentialBackoffとかで繰り返し待つとかしないと危ないっす

YSK: The #googleCloud #PhpSdk ExponentialBackoff (github.com/GoogleCloudPlatfo…) has a max timeout of 60s per try (set as const).
Was kinda surprised. Expected ExponentialBackoff(10) to have a guaranteed retry time of 1024s. It's only ~300s instead & just killed some #bigQuery jobs.
