planning
The Thing-deadline calculus
The best-laid plans
But bulldozers move mountains
Good design is redesign
Obsessed with absolute numbers
A warning against the limitations of my own prescriptions
The plan must anticipate all that is needed
Many a corner office
Individuals matter
Driving engineers to an arbitrary date is a value destroying mistake
The value-destroying effect of arbitrary date pressure on code
An Article by Gandalf HudlowThe mandate from above is clear, just get it done! Avoid everything that's in the way: all advice, all expertise, all discovery efforts that detract from hitting the Date™!
What these organizations don't realize is that all software change can be modeled as three components: Value, Filler and Chaos. Chaos destroys Value and Filler is just functionality that nobody wants. When date pressure is applied to software projects, the work needed to remove Chaos is subtly placed on the chopping block. Work like error handling, clear logging, chaos & load testing and other quality work is quietly deferred in favor of hitting the Date™.

Planning doesn't make for better software
A Fragment by Robin RendleMy own time in a Silicon Valley startup has proved this much to be true; planning doesn’t make for better software. In fact today our design systems team doesn’t have sprints, we don’t have tickets or a daily standup. Each day we come to work, figure out what’s the most important thing that we could be doing, and then we—gasp!—actually do it.
Watching so many other teams slowly flail about whilst they plan for quarter 3.2 of subplan A, whilst our team produces more work in a week than they all do combined in a quarter has been shocking to me.
After four years of working in a large startup, I know what I always assumed was true: you don’t need a plan to make a beautiful thing. You really don’t. In fact, there’s a point where overplanning can be a signal of inexperience and fear and bullshit. The scrum board and the sprints and the inane meetings each and every day are not how you build another Super Mario 64.
Instead all you have to do is hire smart people, trust them to do their best work, and then get the hell out of their way.
Yagni
A Definition by Martin FowlerYagni originally is an acronym that stands for "You Aren't Gonna Need It". It is a mantra from Extreme Programming that's often used generally in agile software teams. It's a statement that some capability we presume our software needs in the future should not be built now because "you aren't gonna need it".
The small web is beautiful
I believe that small websites are compelling aesthetically, but are also important to help us resist selling our souls to large tech companies. In this essay I present a vision for the “small web” as well as the small software and architectures that power it.
Why aim small?
Why aim small in this era of fast computers with plenty of RAM? A number of reasons, but the ones that are most important to me are:
- Fewer moving parts. It’s easier to create more robust systems and to fix things when they do go wrong.
- Small software is faster. Fewer bits to download and clog your computer’s memory.
- Reduced power consumption. This is important on a “save the planet” scale, but also on the very local scale of increasing the battery life of your phone and laptop.
- The light, frugal aesthetic. That’s personal, I know, but as you’ll see, I’m not alone.
Features and complexity
Niklaus Wirth of Pascal fame wrote a famous paper in 1995 called A Plea for Lean Software. His take is that “a primary cause for the complexity is that software vendors uncritically adopt almost any feature that users want”, and “when a system’s power is measured by the number of its features, quantity becomes more important than quality”.
Solving the problem of software bloat
But instead of just complaining, how do we actually solve this problem? Concretely, I think we need to start doing the following:
- Care about size: this sounds obvious, but things only change when people think they’re important.
- Measure: both your executable’s size, and your program’s memory usage. You may want to measure over time, and make it a blocking issue if the measurements grow more than x% in a release. Or you could hold a memory-reduction sprint every so often.
- Language: choose a language that has a chance.
- Remove: cut down your feature set. Aim for a small number of high-quality features. My car can’t fly or float, and that’s okay – it drives well.
- Say no to new features: unless they really fit your philosophy, or add more than they cost over the lifetime of your project.
- Dependencies: understand the size and complexity of each dependency you pull in. Use only built-in libraries if you can.
Raw size isn't enough
A few months ago there was a sequence of posts to Hacker News about various “clubs” you could post your small website on: the 1MB Club, 512KB Club, 250KB Club, and even the 10KB Club. I think those are a fun indicator of renewed interested in minimalism, but I will say that raw size isn’t enough – a 2KB site with no real content isn’t much good, and a page with 512KB of very slow JavaScript is worse than a snappy site with 4MB of well-chosen images.
...[Instead, it's about] an “ethos of small”. It’s caring about the users of your site: that your pages download fast, are easy to read, have interesting content, and don’t load scads of JavaScript for Google or Facebook’s trackers.
