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.
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:

How should we give and receive feedback? we wonder. How much, and how often, and using which new app? And, given the hoopla over the approaches of Bridgewater and Netflix, how hard-edged and fearlessly candid should we be? Behind those questions, however, is another question that we’re missing, and it’s a crucial one. The search for ways to give and receive better feedback assumes that feedback is always useful. But the only reason we’re pursuing it is to help people do better. And when we examine that—asking, How can we help each person thrive and excel?—we find that the answers take us in a different direction.
To be clear, instruction—telling people what steps to follow or what factual knowledge they’re lacking—can be truly useful: That’s why we have checklists in airplane cockpits and, more recently, in operating rooms. There is indeed a right way for a nurse to give an injection safely, and if you as a novice nurse miss one of the steps, or if you’re unaware of critical facts about a patient’s condition, then someone should tell you. But the occasions when the actions or knowledge necessary to minimally perform a job can be objectively defined in advance are rare and becoming rarer. What we mean by “feedback” is very different. Feedback is about telling people what we think of their performance and how they should do it better—whether they’re giving an effective presentation, leading a team, or creating a strategy. And on that, the research is clear: Telling people what we think of their performance doesn’t help them thrive and excel, and telling people how we think they should improve actually hinders learning.
Underpinning the current conviction that feedback is an unalloyed good are three theories that we in the business world commonly accept as truths. The first is that other people are more aware than you are of your weaknesses, and that the best way to help you, therefore, is for them to show you what you cannot see for yourself. We can call this our theory of the source of truth. You do not realize that your suit is shabby, that your presentation is boring, or that your voice is grating, so it is up to your colleagues to tell you as plainly as possible “where you stand.” If they didn’t, you would never know, and this would be bad.
The second belief is that the process of learning is like filling up an empty vessel: You lack certain abilities you need to acquire, so your colleagues should teach them to you. We can call this our theory of learning. If you’re in sales, how can you possibly close deals if you don’t learn the competency of “mirroring and matching” the prospect? If you’re a teacher, how can you improve if you don’t learn and practice the steps in the latest team-teaching technique or “flipped classroom” format? The thought is that you can’t—and that you need feedback to develop the skills you’re missing.
And the third belief is that great performance is universal, analyzable, and describable, and that once defined, it can be transferred from one person to another, regardless of who each individual is. Hence you can, with feedback about what excellence looks like, understand where you fall short of this ideal and then strive to remedy your shortcomings. We can call this our theory of excellence. If you’re a manager, your boss might show you the company’s supervisor-behaviors model, hold you up against it, and tell you what you need to do to more closely hew to it. If you aspire to lead, your firm might use a 360-degree feedback tool to measure you against its predefined leadership competencies and then suggest various courses or experiences that will enable you to acquire the competencies that your results indicate you lack.
What these three theories have in common is self-centeredness: They take our own expertise and what we are sure is our colleagues’ inexpertise as givens; they assume that my way is necessarily your way. But as it turns out, in extrapolating from what creates our own performance to what might create performance in others, we overreach.
Research reveals that none of these theories is true. The more we depend on them, and the more technology we base on them, the less learning and productivity we will get from others. To understand why and to see the path to a more effective way of improving performance, let’s look more closely at each theory in turn.
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.
