Not sure of the specifics, but if certain glyphs are not in a font, it falls through to the next font in the stack. Got a repro?

Most advanced javascript developers don't know about these features, so no worries at all. :) (We're chatting now)

There are a couple DevTools features that make this kind of reverse-engineering much easier. Oftentimes, the obfuscation relies on turning strings into functions. You can watch all this happen with: `monitor(eval); monitor(Function)` That&#

My primary codebase ingests data with a mix of seconds, milliseconds, and microseconds. We've held it at bay for a while, but it requires some mental overhead unless we've baked the unit into each variable name. We're likely

I've also spent time profiling shell startup and found conda's init wasn't fast. (And that's consistent in fish shell, tol) Your found solution is elegant; I'll adopt it. nvm and rvm both have initializations have

PSA: You can email support@github to ask them to "detach my repo as a fork", in case the repo has matured so much it shouldn't have the "forked from …" treatment.

In the 90s, I bought a Brother word processor machine from a yard sale and I used it for journaling in high school years. It saved to a 3.5" floppy (non-HD?), which I've kept. About a decade ago I was hoping to recover the data. I

Speaking as the TL of Lighthouse and PageSpeed, I can comfortably say that adding complexity is antithetical to our goal. Quality UX and a reliably performant web is what we want for all users. Ideally, folks would use a thinner stack with

You improved the speed of something. It took 430ms before and now just 160ms. But how do you quantify that? https://how-much-faster.glitch.me/ gives you a few options for how to word things.

An interesting convention that ~started with Firebug was the use of angle brackets in the DOM/Elements view. (eg a DIV element is shown as `<div>`). HTML, as a text format, uses angle brackets to denote tags. But DOM is an in-mem

I don't know what you're measuring (onload?), but it's not giving you enough precision to make a conclusion about the performance of the HTML parser. If you profile the page w/ devtools Performance panel, you'll se

Within the webperf folks at Google, we've certainly debated if CLS is a performance metric. The loose consensus is that it's not... it's a predictability and UX metric. Also "Core Web Vitals" is deliberately not sc

In CSS, the hand cursor is called a 'pointer' cursor, so I think that's what was intended. For anyone who hasn't internalized this, including the app's users, I imagine this is quite confusing. :) IIUC 'regular
