What does software development, a pendulum, and the genie have to do with each other? You wouldn't think much, but in fact, just like the motion of a pendulum is dependent on it's size, weight, and how hard it's poked, software development works the same way. And the genie is poking at it. Hard.

HT to @tottinge He said this way better than I can. Why, in the name of all that's good, are we still writing legacy code in 2025?
-
Friendgineers: Does practice make perfect? Maybe. But are you perfecting the right thing? That's a question we should be asking far more often than we actually do.
-
Friendgineers: Power dynamics are real and play a surprisingly large role in what gets done. Even when people with power don't realize the impact they're having.
-
Friendgineers: The internet is a great place for learning. It's also a place where you can find some REALLY bad ideas. It takes critical thinking to know if any particular idea is good or bad, IN YOUR SITUATION. Somethings though, are just bad ideas.
-
Friendgineers: I've often felt that we in the software business prioritize immediate gain over long term success. Sometimes that's needed, but in the long run, taking a long term view always pays off.
-
Friendgineers: We all agree that good culture is important. We even mostly agree on what good culture is. But how do you identify it, and how can you encourage it?
-
Friendgineers: You have the power of the pen. Writing down the impact of what you're going to do is constrains your impact, but it can also open up possibilities.

Friendgineers: You need to be clear about your goals and always work towards them. You also need to accept the reality that your goals may exceed your grasp. Then include that reality in your plans.
-
Friendgineers: There are lots of superpowers you want as a developer. One of the best ways to get them is to have options. That means doing the hard work up front so you have optionality.
-

-
Friendgineers: You need to remember who you're really talking to when you write code. It's NOT the compiler and it's not the reviewer, although they need to understand. It's the maintainer. Write for the maintainer. You'll thank yourself later
-
Friendgineers: How can we work faster? There are those who say AI makes us faster by writing the code for us. But really, when was the last time typing was actually the bottleneck? Maybe when you're actually typing, but it's almost NEVER the limiting factor over the lifetime of a project.
-
Friendgineers: When requirements change out from under you it is very disruptive. But did they really changing, or are we just understanding them better? Not understanding the requirements is a shared communications problem.
-
Friendgineers: We all think we're writing new code, but the reality is, in almost all cases, we're modifying existing code. How do things change if you think of how you're modifying existing code EVERY time you write any code?
-
Friendgineers: Did you know your data talks to you? It's talking all the time, but we usually don't listen to it. As part of your design process, you should start listening to your data.
-
Friendgineers: I've said it before and I'll say it again. Handling time right is hard. Not just in your production code, but in your tests as well. We have met the enemy, and it is Time.Now().
-
Friendgineers: Continuing on why software engineering is engineering, a discussion of estimates. Yes, they're hard for software. Just like they're hard for all engineers. Just another way Software Engineering is Engineering.
-
Friendgineers: Engineering is all about balancing constraints, both physical and non-physical. The domain doesn't matter. Software engineering is just as much engineering as as designing a building or a bridge.

Friendgineers: Move fast and break things sounds like the opposite of Slow is Smooth, Smooth is Fast, but what it they're opposite sides of the same thing?
