If I Could Wave a Magic Wand (wilsoniumite.com)
We often talk about rewriting code and almost as often talk about whether big rewrites are even a good idea.

A Local-First Case Study (jakelazaroff.com)
I just got back from a travel sabbatical. While the trip turned out great, the planning process was decidedly… less so. Figuring out six months of travel is a daunting task, and I quickly became dissatisfied with existing tools.
