Teaching changed how I design technical things
Trying to help other people learn made me much less interested in showing off and much more interested in clarity.
Archive / notebook shelf
Notes, essays, build logs, and a few posts that still have sawdust on them.
Personal site by Jason Eran. Projects, notes, experiments, and one glowing visitor globe. This archive is not on a content treadmill. Some pieces were written fast. Some sat half-finished for months until I had something less polished and more honest to say.
Start here
Three good places to get my tone.
These are the easiest entries if you want to know how I think before you decide whether to keep reading.
I take software seriously, not solemnly
Reliable systems matter more to me than performative seriousness. Humor, calm, and clear thinking can live in the same room.
Why I still like personal sites that feel like rooms
A short note on wanting this corner of the internet to feel more like a place you can step into than a feed you have to keep up with.
Core writing
Essays
Longer arguments about performance, architecture, and product trade-offs.

Latency is a trust signal, not a performance afterthought
Fast interfaces shape user confidence before anyone notices architecture, reliability charts, or clever implementation details.
Edge is a placement decision, not a belief system
The edge is excellent at some jobs, distracting for others, and most useful when treated as a placement choice instead of a product religion.
Practical notes
Field Notes
Operational patterns, lightweight checklists, and lessons from shipping small systems.
A site can be playful without becoming noisy
I like interfaces with a wink, but I trust the ones that know when to quiet down and let me stay.
A lot of technical work is really translation
The hard part is often not only building the system. It is helping different people understand the same system from where they stand.
The smallest observability stack that still helps on a personal app
Small projects do not need enterprise telemetry theatre, but they do need enough signals to answer the next useful question quickly.
Site lab
Build Notes
Implementation notes about the blog itself and the experiments running behind it.
Launching a static-first engineering blog with one living island
Why this blog starts with Astro, a deliberate WebGL island, and a bias toward edge-readable systems.
Astro islands are a product choice, not just a framework feature
Treating hydration as a design constraint leads to cleaner reading experiences and a healthier performance budget.
