I have an “everything” Linux server currently running Slackware 15. Sometimes I need to create users in /etc/passwd for some particular use case, but both my Postfix and Dovecot authenticate against /etc/passwd to grant access. It took a long time to figure out how to get that done. Finally I did it: Postfix Edit /etc/postfix/master.cf; …
Continue reading Blocking Postfix/Dovecot access for some local usersAssertions Qualified and motivated teachers have run into roadblocks for as long as the government education system existed. I believe that in recent decades the entire education system from kindergarten to postdoctoral degrees has devolved to the point where no honest person can claim that a new graduate with any credential is necessarily capable of …

Unselfish and awesome people who do good not only for themselves but for many others too. In …

One of the things that always pissed me off about non-Slackware distributions is the amount of time it takes to install new software. Sure in Slackware I …

I don’t remember the last time it was so blindingly obvious that the world is completely filled with idiots. There’s a thing going around the world called the Coronavirus Disease 2019 (COVID-19). It’s severity is about the same as a cold. Maybe a flu. And the world …
Continue reading Mass hysteriaI hate, hate planned obsolescence. Almost as much as I hate religious idealistic stupidity such as that described below.
