i do the same for Content Security Policy: `default-src 'none'` by default, then add what i need when i need it.

agreed. i think the economics of ramen make less sense outside of japan, where it’s more expensive and turnaround is slower because folks linger longer (often to amortize the cost of waiting to get seated in the first place).

this reminds me of a naive and happier time in tech, when i built a game called ramendan with twitter’s open API. you had to eat ramen every day for dinner, and tweet proof with the hashtag #ramendan, link to a photo (this was before twitter supported images), and geotag it so that we could make sure it was after sundown in your timezone.

i went super deep on 140-byte code golfing[1] back when twitter was taking off, and it changed the way i think about code. for a brief while we had a small community collaborating on byte-squeezing techniques[2], and i was constantly amazed at the creativity that this constraint brought about, from mandelbrot renderings to sudoku solvers. possibly the best part was more than a decade later when i found my golfed UUID implementation[3] deep in my employer's codebase.

In my experience, as long as a controlled window is communicating with the SW, the connection will remain alive.

A service worker would work fine; the connection would be instantiated from the SW and each window/worker could communicate with it via navigator.serviceWorker.

Instead of adding a non-standard API to opt-out of existing networking functionality, it would be great to see a lower-level networking primitive to unlock these kinds of use cases. I wrote more (with a proof-of-concept) here: https://readable.writable.stream

New comment by jedschmidt in "Lave: eval in reverse"

jedschmidt — Thu, 10 Mar 2016 07:21:55 +0000

Sure, as it could with any part of your app, including wherever your JSON.parse code lives.

Not _quite_ arbitrary; the only code run is that generated by lave. Arbitrary code present in functions is parsed, but not run.

Absolutely. The downside of running a full-blown eval() exists in JSON too, it's just that the eval() there is taking place in the reviver function, which requires a lot more coordination than a self-contained file.

As far as efficiency, I'd think for most uses the issue would be on the JSON.parse end. In this case, lave might be more efficient, since JSON reviving often ends up creating temporary objects that need to GC'ed after reification.

My situation is for an intranet environment, so I suppose I could just ask nicely that they don't change validations. But chances are most of my target users aren't familiar enough with Google Spreadsheets to even get that far.
