GitHub
I'm REDES01 on GitHub. That's the best place to reach me: open an issue on the relevant project, or find me through my profile. I read everything, usually within a few days.
About something you read
If a post has a mistake, or a trick in it didn't work for you, tell me — I'd rather fix a post than leave it wrong. Mention which post and what you tried.
Leave a tune
If you only want to say hi, the guestbook on the home page lets you leave eight notes instead of words. It's the nicest message I get.
