Discover gists

These are some notes on the performance work that went into alien-signals. I'm sharing them not as a definitive guide, but as a log of a few key discoveries. The hope is that some of these findings might be useful to others tackling similar problems in high-performance JavaScript.

The Origin: Push-Pull-Push

My journey into the depths of reactivity performance began with Vue. I was trying to solve a specific problem in Vue 3.4: even if a computed's value didn't change, it would still trigger downstream computations and effects. This seemed inefficient. My attempt to fix this resulted in a pull request (vuejs/core#5912) that, after a year of discussions, was eventually merged. This PR introduced the Push-Pull-Push model to Vue 3.4, a model also adopted by libraries like reactivity.

For a time, I thought this was near-perfect. Then I saw the plans for Vue 3.5, which adopted a doubly-linked list but also moved to a pure pull-based model. I was still convinced

Running OpenClaw Without Burning Money, Quotas, or Your Sanity

TL;DR

OpenClaw is useful, but most of the pain people run into comes from letting one model do everything, chasing hype, or running expensive models in places that don't need them.

What worked for me was treating OpenClaw like infrastructure instead of a chatbot. Keep a cheap model as the coordinator, use agents for real work, be explicit about routing, and make memory and task state visible. Cheap models handle background work fine. Strong models are powerful when you call them intentionally instead of leaving them as defaults.

You don't need expensive hardware, and you don't need to host giant local models to get value out of this. Start small, get things stable before letting it run all the time, and avoid the hype train. If something feels broken, check the official docs and issues first. OpenClaw changes fast, and sometimes it really is just a bug.

	- Open Notepad.
	- Copy everything from the comment below and paste it in Notepad.
	- Press X to close Notepad, it will ask you to save the file.
	- Choose an appropriate name eg. TransMac_Reset_Trial.cmd

	You can place the file whatever you like as long as you have installed TransMac in the default install path.

	You can also put TransMac_Reset_Trial.cmd in the same directory as TransMac.exe and run it from there.
	This is useful if you want to put TransMac.exe in another path than default.
