Kevin Boone ☛ Kevin Boone: They don’t make ’em like that any more: tone controls
Tone controls boosted or cut frequencies in the bass and treble range. There never was much consistency about what frequencies constituted ‘bass’ and ‘treble’, beyond bass being ‘low-ish’ and treble being ‘high-ish’. The Leak 130 has a bass adjustment that centres at about 50Hz, and a treble about 50kHz. Of course, human hearing doesn’t extend to 50kHz – we’re firmly in bat territory here. But the frequency cut-off is relatively smooth, so both bass and treble controls affect a rather wide range of frequencies. In practice, the bass will have some discernible effect on all frequencies up to about 500Hz, and the treble all frequencies down to about 1.5kHz.

Jeff Geerling ☛ Save video still frames from QuickTime Player with a shortcut
Almost 15 years ago, I wrote Grab a Single Frame from a Video in QuickTime X. And for many years since, I slightly modified that workflow. Instead of using Preview, I would use pngpaste, and paste the copied frame from QuickTime player into a file.

James Kerr ☛ DOM IDs are a real pain in my apps
The standard way to dynamically update HTML content in Ruby on Rails relies heavily on DOM IDs. These IDs are used to identify the target HTML element for an update. The ID must be present on the original page, and in the subsequent partial updates.

University of Toronto ☛ Some stuff on how Linux consoles interact with the mouse
On at least x86 PCs, Linux text consoles ('TTY' consoles or 'virtual consoles') support some surprising things. One of them is doing some useful stuff with your mouse, if you run an additional daemon such as gpm or the more modern consolation. This is supported on both framebuffer consoles and old 'VGA' text consoles. The experience is fairly straightforward; you install and activate one of the daemons, and afterward you can wave your mouse around, select and paste text, and so on. How it works and what you get is not as clear, and since I recently went diving into this area for reasons, I'm going to write down what I now know before I forget it (with a focus on how consolation works).

How To Run FSR4 On Steam Deck And Other Linux Devices
The latest iteration of AMD’s upscaling technology, FSR4, was initially designed for RDNA4 graphics cards. Thanks to modders, however, the feature has been adapted to work on RDNA2 and RDNA3 hardware, which includes the Steam Deck, Steam OS, and Linux systems. The result is a new way for handheld and Linux players to improve image quality in supported titles, though with a few compromises in performance.
Installing FSR4 requires some manual setup, but once configured, players can enjoy sharper detail, reduced shimmering, and generally cleaner visuals compared to earlier versions like FSR 2.1. It is worth noting that these improvements often come with reduced frame rates, making frame caps or performance tweaks advisable.
