My name is Vince and I'm a technical packrat. ( Hello Vince.... )
I have notes from the first Dallas .Net User Group meeting in 2001 and the first Microsoft MSDN meetings in Dallas around 1998. I have an ascii chart in my wallet but soon to be on my phone. I have books related to project management in the late 80's. I still have 8086 assembly and SQL 6.5 books.
Why? I'm a technical packrat.
After 20 years of development, I actually know who I am and what I want to focus on. Technology moves like a train around mountains, but it still moves forward. Some good advise I've heard is that if we don't read it in 3 months, throw it out. It feels good to throw away obsolete things that no one needs. A trip to the local Goodwill will be a relief.
What's in your wallet?
