Fast

Craig Mod in “Fast Software, the Best Software”:

I love fast software. That is, software speedy both in function and interface. Software with minimal to no lag between wanting to activate or manipulate something and the thing happening. Lightness.

Software that’s speedy usually means it’s focused. Like a good tool, it often means that it’s simple, but that’s not necessarily true. Speed in software is probably the most valuable, least valued asset. To me, speedy software is the difference between an application smoothly integrating into your life, and one called upon with great reluctance.

[…] Because — it’s not quite as fast. We’re talking milliseconds, but it’s enough that you feel the difference.

[…] Still, the slowness feels indicative of unseen rot on the inside of the machine. The slowness is like an off smell. I don’t trust the application as much as I would if it didn’t slow down […]

Speed and reliability are often intuited hand-in-hand. Speed can be a good proxy for general engineering quality. If an application slows down on simple tasks, then it can mean the engineers aren’t obsessive detail sticklers. Not always, but it can mean disastrous other issues lurk. I want all my craftspeople to stickle.

[…] I love software that does this: Software that unbloats over time. This should be the goal of all software. The longer it’s around, the more elegant it should become. Smooth over like a river stone.

[…] But why is slow bad? Fast software is not always good software, but slow software is rarely able to rise to greatness. Fast software gives the user a chance to “meld” with its toolset. That is, not break flow.

[…] It feels — intuitively — that software (beyond core functionality) should aim for speed. Speed as a proxy for efficiency. […]

Ultimately, to be fast is to be light.

He's talking about software — where it's most perceptible —, but I think this could also be easily applied to physical objects.


As an aparté, but similarly, Craig also wrote this sentence that I like a lot in his latest Roden newsletter:

Part of me wishes there was more of a trend in the startup world to build sustainably small, single-serving, hyper-focused, culturally-impactful businesses.
