Did I just find a bug in Node.js 🫠

⚙️ Case: fetch a range request ("range: bytes 1-3") on an object URL

✅ Expected: returns 3 bytes

🟥 Observed: returns 2 bytes

The range is inclusive: both the "start" and "end" bytes must be returned. In this case, Node.js wrongly ignores the "end" byte!

See the code examples:

- white background: the correct behavior, in the browser

- dark background: the bug, in Node.js

As CSSNext is now deprecated you can use instead the Postcss plugin "PostCSS Preset Env" to lets you use modern CSS in your style sheet.

you benchmark your node/ruby/python software on your fancy new m4 mbp and celebrate 500ms response times.

I benchmark my rust software on a $30 potato computer that may as well have 256mb of RAM and celebrate 800ms response times.

we are not the same.

electron and Tahoe and a temporary fix

If your Tahoe mac is causing a system wide lag, there’s a known issue with Electron and Mac OS Tahoe. By now a lot of the usual suspects have issued a fix – https://avarayr.github.io/shamelectron/

However, a big hold up still seems to be Cursor. Here’s a script you can run to detect which apps in your system still has an issue: https://github.com/tkafka/detect-electron-apps-on-mac/tree/main

In my case, it’s just cursor that’s causing the issue. The temporary fix (that must be issued after every login) is

It turns out Electron was overriding a private AppKit API (_cornerMask) to apply custom corner masks to vibrant views.

Either way, the Tahoe path has been rough, as expected. However, this is a purely Electron thing relying on a private AppKit API which they never should have been using. Which they wouldn’t have to revert to if Apple had provided a more robust API for them to fix the need. Which in turn wouldn’t be an issue if they had support for robust PWAs. Which in turn wouldn’t have been an issue if not for the chokehold they are trying to put on the web to bolster native app development, which just feels anachronistic given native apps “won” for mobile.
