A very famous blog post is Straight White Male: The Lowest Difficulty Setting There Is by John Scalzi [1]. In that post he clearly describes that life isn’t great for straight white men, but that there are many more opportunities for them. Causes of Death When this post is mentioned there are often objections, one […]
One thing I should have learned before (but didn’t) and hope I’ve learned now is to photograph sysadmin work. If you work as a sysadmin you probably have a good phone, if you are going to run ssh from a phone or use a phone to read docs while in a server room with connectivity […]
As a follow-up to my post with Suggestions for Trump Supporters [1] I notice that many people seem to have private definitions of words that they like to use. There are some situations where the use of a word is contentious and different groups of people have different meanings. One example that is known to […]
In February I reviewed a Thinkpad X1 Carbon Gen 1 [1] that I bought on Ebay. I have just been supplied the 6th Generation of the Thinkpad X1 Carbon for work, which would have cost about $1500 more than I want to pay for my own gear. ;) The first thing to note is that […]

I’ve had some discussions with Trump supporters recently. Here are some suggestions for anyone who wants to have an actual debate about political issues. Note that this may seem harsh to Trump supporters. But it seems harsh to me when Trump supporters use a social event to try and push their beliefs without knowing any […]
There’s a lot of advice about how to create and manage user passwords, and some of it is even good. But there doesn’t seem to be much advice about passwords for daemons, scripts, and other system processes. I’m writing this post with some rough ideas about the topic, please let me know if you have […]
This post is about my latest idea for learning about computers. I posted it to my local LUG mailing list and received no responses. But I still think it’s a great idea and that I just need to find the right way to launch it. I think it would be good to try cooperative learning […]
