I've never met a candidate who worked on the internals of the JVM or Java compiler, so I can't say we would hire him. I have met more candidates who know what technology is used as the backend of a website, than who know the internals of the JVM. Also, is he still aware of the current intrinsics of the JVM and Java compiler, or was that 10 years ago? My post was very blunt, like I said. I read through every resume I get, and I would be interested in somebody who has JVM/Java compiler knowledge. As for COBOL: I don't need a COBOL programmer, we have no COBOL and won't write COBOL. We do have a website, which requires development though. If you had to pick one, which would you hire: A COBOL developer with no Web development skills, or a Web developer with no COBOL skills. I have a view on web development as well, but that's a long post as well. I prefer JSON over XML, I've worked with both, and I struggled with tooling for XML, validation, parsing and the whole 'who creates the WSDL' discussion. I miss some good JSON validation though (and JSON comments). YAML I like less, because using indentation as for logic is asking for problems. We don't use NOSQL. Our data is very relational.
