- I wanted to see how difficult it would be to add Go's defer statement to the TypeScript compiler, but by the time I finished I was convinced it probably shouldn't exist.In Go, the defer statement delays the execution of a function until the surrounding function finishes. It's...
- Engineers often complain that visibility should be their manager’s job. In other words, they think engineers should be able to focus on the code, while their manager figures out who’s doing well and rewards them.

- TL;DR Why I think software development is starting to feel a little more like conducting an orchestra. There’s a shift happening in software development that I don’t think we’re talking about clearly enough. For the last couple of years we’ve framed AI as a productivity tool....
- End of July? Seriously? Feels like yesterday when I celebrated New Year’s Eve, and all of a sudden it is the end of July. Can we all slow down a little, please? Not a little. Slow down! You, time, the world. Pretty please! I’m in a good mood today, but not in a good one to write...

- Warning! Do not try any of this at home! Messing with internals of electronic devices is dangerous and can lead to electrical fires, serious injury and even loss of life. My dad started using a super 8 film camera as early as 1967 (the system was launched in 1965). He stopped...

- Every zeitgeist comes with new design idioms unique to its challenges. Many of them disappear as fads change, but others bake themselves into deeper parts of existing software interaction paradigms. For example, there’s the hamburger menu (≡) which saw a proliferation during the...
- Lorenz and Little: How Much Does Your Tail Cost? Lorenz and Little sounds like hipster burger bar from 2015. MathJax = { tex: {inlineMath: [['\\(', '\\)'], ['$', '$']]} }; It’s time for Marc’s Amateur Statistics Corner! Today: why I pay a lot of attention to tail latency when...
