I often wish that software developers were criminally liable for the code they write. I have disdain for this way of working. It’s reckless.

WordPress Caching
I had some WordPress performance issues over the weekend. The website was performing so poorly that connections timed out. I traced the problem to some changes I made in the MySQL configuration. I want to spend more time learning about that so that I can find tune thing. To recover, I created a new Digital Ocean VPS and copied the default MySQL configuration to my VPS. The website performance returned.
By the time I had things squared away, my mind was soon in tweaker mode, so I made sure APCu Object Cache for PHP7 was installed, then I installed and configured the WP LCache and W3 Total Cache plugins.
There are still some issues I want to work on fixing:
- render-blocking CSS and JavaScript
- MySQL read performance
The Feedback Fallacy
If you’re a human being and you’ve ever given or received feedback, read this humdinger of a Harvard Business Review article. This is the second article on feedback that I have read this week. Would love to have a dialogue about this.
My favourite part of the article is this one paragraph.
... although science has long since proven that we are colour-blind, in the business world we assume we’re clear-eyed. Deep down we don’t think we make very many errors at all. We think we’re reliable raters of others. We think we’re a source of truth. We aren’t. We’re a source of error.
Emphasis mine.
