You made the point that I was trying to make: implementations are not secure. A programming language can follow a philosophy but implementations never quite line up with the theory. We only use implementations of the theory and experience shows that implementations all have vulnerabilities.

I don't have a short attention span and I'm not hyperactive. I spend a lot of time thinking about things. I deduce things noticeably faster than my peers as long as it's not socially related. I have intense focus as long as something remains stimulating. When things lose my interest or are pointless they become tedious and it's not about attention span. I cannot stop worrying about assigned tasks to the point of anxiety. There is a mental barrier and I cannot work on the task despite intentions and efforts to do so. Medications don't really help me. They do at first, then they become less effective. An interesting side note about meds: The first time on meds I finally could see social cues and body language. It was a whole new world. I still see them off the meds now that I know about them but I may have trouble understanding what they mean due to lack of experience in receiving those signals. Getting proper sleep, nutrition, and having regular, serious exercise help more than meds. The affliction is very real. Just because you can't see it or refuse to believe in it doesn't change the fact that it impacts the lives of others.

"Unix: just enough potholes and bear traps to keep an entire valley going."

If you don't understand how to use sharp tools, you may hurt yourself and others. Documentation for fork() clearly explains why and when fork() returns -1. Those that find the man page lacking or elusive may get more out of an earnest study of W. Richard Stevens' book, Advanced Programming in the UNIX Environment. In any case, every system programmer should own a copy and understand its contents.

Until the sequence rolls over. Why design a schema with built in failure (an integer PK that overflows)?

In the 90s I built a FreeBSD firewall using discarded PC parts. It took 10.5 hours to build world and kernel. There were 2 power outages that forced me to start over each time. I bought my first personal UPS to fix that problem. I would learn how to cross compile instead of waiting 12 hours.

It's interesting to watch ordinary people attempt to dabble in currency. How many criminal organizations, governments, and financial institutions (redundant?) the world over have people who wake up everyday just to manipulate the value of currency? For example, a common criticism of China is that they purposely manipulate their currency to devalue the US dollar. In which ways could such organizations impact a new currency like bitcoin? Simple theft doesn't work very well unless immediately converted to cash, just like tangible goods being fenced, often below true value. Was it really just theft?
