ResearchGate | Berlin, Germany | ONSITE: Working From Home, must come to Berlin | Visa support

Position is to work mostly with PHP in a very fullstack environment. You'll touch Java, golang, hadoop/flink and write queries to run in our hadoop clusters.

I've read both documents a couple of times. I wonder what is in there that you believe should be in a "deep dive" or what is missing there in your opinion.

Thanks for your feedback and I'm keen to hear more from you :)

Thanks a lot! I blindly fetched this from the reference mentioned there. I'll update this as soon as I have time (probably during this week) and also let the author of the referenced post know about it.

I might be wrong here, as I'm not so close to Java development. But a language implementing JIT, at least to me, is interpreted.

Could you please point an implementation detail where a JIT-capable engine doesn't include interpretation in its runtime?

In every case, thanks a lot for your feedback!

Well, from CS compiler theory point of view it is not.

For example in .NET, MSIL goes directly into a pipeline that produces native. You can easily validate that RyuJIT has no interpretation.

Or for example, watchOS applications packaged with bitcode, get JIT compiled at installation time.

V8 had only baseline compilation until much later https://v8.dev/blog/ignition-interpreter

It's not super exotic to do this.

I should probably add this kind of thing to the article then. It is nearly impossible to state "Language X is compiled/interpreted/jitted".

I didn't explicitly say that JS doesn't come with JIT, because I'd be putting Node.JS and every browser engine in the same bag. I simply can't be sure about all of them.

I'll add very soon this caveat that the dialect (js, php, python) doesn't really matter and make it clear that I'm talking about engines, possibly directly point to them.

I hope you understand, though, that I wanted to make JIT as a concept understandable. The language comparisons are secondary.

Thanks a lot for your feedback!

Thank you all for sharing your comments and thoughts. I'm unfortunately out of time today, but I'll try to address your comments asap :)

Cheers!

Hey man, author here. Thanks for the feedback. I recently added adsense there and I'm testing with the amount of ads in the page. Currently I'm letting AdSense decide how many ads it should place and where.

But if you believe the amount is so harmful for your experience, don't worry. I'll be more than glad to reduce this amount.

Cheers!

Small correction: php IS compiled, just not the way we're used with the term. See https://thephp.website/en/issue/php-8-jit/ for more information.

The answers below show a good solution for this issue: use static analysis tools in build time and potentially even as a pre-commit hook.

Thanks for pointing this out. It annoyed me a lot as well. The whole "dark mode" css was a "better than nothing" thing, and now I'm collecting the "must fix" things. This is definitely on the list!

That said: the website is open source, feel free to submit a PR if you find time before I do :D

Nothing that tools like Rector can't help you with.

I believe this extra step is incredibly important, given most of your dependencies you won't control and forcing strict types to them is not very clever IMO.

I guess it wouldn't work if your dependencies weren't easily seperable from the rest of the code. in this case there are no dependencies, it's all custom cobbled together, for better or worse
