Ask HN: how do you objectively prove what you have independantly learned

Particularly in regards to programming. If you state in an application for example that you know MySQL or that you are able to programme say in php, how do you objectively prove this. Is there any reconsigned examining bodies which may provide you with a certificate?

  • It seems to me that having an open-source pet project or two that uses the relevant technologies would suffice.

  • I'm more likely to believe specific things you've done over general things you claim to know particularly when it comes to specific technical systems. Don't tell me you "know" MySQL. Instead, tell me about the things you did to insure I can't take down your system by injecting a call to BENCHMARK() or about the time you were able to get the database working after InnoDB force recovery didn't work.

  • Either certify or build something public using your skills, I guess.

  • this is basically the purpose of certifications.

    other things that work are employment references and code examples.
