Hello. I'm reading Mafiaboy book by Michael Calce and I want to know in below text what does "dumb" mean? Can it mean "Silent" ? "The RCMP had tracked me online for a couple of months after I learned I was a suspect in the attacks. I was reckless enough to still use many of the networks I had compromised, but I wasn't so dumb that I continued to do the exact same things." Thank you.
