the customers spending billions on the big cloud providers are entitled to much more rigorous and detailed reporting (incl historical data) for end-user-visible performance... I wo…

(disclaimer: I am one of the people who started opentracing) Someone sent me this HN thread – nice to see the questions here! OpenTracing has had a big end-of-2017 with support lan…

"OpenTracing-compatible" is strict API compatibility in any supported language. The cross-language spec is "terminology-based" since it's, well, cross-language. There is an open is…

what a lovely design!

I don't think that doing manual memory management doubles dev time for experienced devs, no... I just mean that, if you're trying to eliminate GC hiccups by, say, writing a custom …

This is a lazy answer, but it needs to be said: it depends on the context and the number of roundtrips to the cache. If we're talking about a vanilla object cache, I think that it …

It really did take twitter many years to rearchitect and break their most problematic dependencies on Rails, yes... my understanding is that it was a 4-year process.

For my own project, the GC tradeoff with Go (or Java) is acceptable given the relative ease of development w.r.t. C++. Since there are better structures in place to explicitly cont…

Sure. So, for any black-box service endpoint, the latency for any given request is obviously just the time it takes for that operation to complete. Ideally one measures both end-to…

I can't resist (this is the OP): you are missing the point. It's not just throughput, it's high-percentile latency. Latency is critical if you have 1 billion users or 100 users, an…

JRuby is of course incompatible with C extensions to Rails; the place I used Rails had such dependencies, and so JRuby was not an option. I agree that JRuby is otherwise preferable…

I don't think anyone is arguing that companies fail to grow because of these languages. It's merely that they would grow more quickly once at scale if they didn't have to spend sev…

(I wrote TFA -- didn't expect it up on HN!) I agree that the post would be more compelling if I wrote a benchmark to demonstrate how much faster an in-memory cache is than an off-p…

Ah, I hadn't seen that, thanks! For what it's worth, "Go" as a language is not really implicated in that, it's more like the `go` cmdline suite that was causing trouble. I would al…

Exactly. With proper discipline and true 100% test coverage, dynamic languages work well. But over time, that ideal is a challenge for most software organizations to actually live …

@dvt, this is the OP here. I was hoping that those who already agree with me about dynamic languages would come to understand that Go is different in this respect. I did a lousy (i…
