what is a real time kernel vs a normal kernel? just "faster"?

'real time' generally means latency guarantees and trading some throughput for consistent low latency for interrupts and scheduling. So faster in some dimensions and slower in others. The Arch Linux wiki has some description of their real time patches: https://wiki.archlinux.org/title/Realtime_kernel_patchset

Arch wiki is an amazing source of practical information. It's like graybeard forums but distilled into a readable text. My last laptop ran Mint distro; whenever I searched around for HW issues it was always their wiki, fully stocked with useful info and steps how to fix stuff.

No. Soft real time can miss some real time deadline. AFAIK Linux RT kernel is designed to hit every deadline, but they just cannot offer a formal proof. So "more-or-less" hard real time.

One of the problems is that the Linux RT kernel doesn’t stop you from using/writing devices/drivers that break those guarantees systemwide, as I understand it.

What kernel can give such a guarantee?

Cookie consent by scrolling doesn't seem like a legitimate way to obtain user consent.

I mean, it's no worse than the standard antipatterns, which are designed to be so easy to click "accept" and so hard to follow the "don't accept" flow. None of them are about coming to an agreement with the user; all of them are about obtaining as much data as possible. Until the EU mandates a handwritten letter to obtain permission for tracking cookies, these demonstrations of bad faith will be our friends on the in…

I just hit agree and let my browser extensions handle the rest by blocking tracking cookies.

I haven't looked around very much, but getting VSTs on something other than a desktop DAW has been something I've wanted for a while, to enable audio from a dumb keyboard, Without a dedicated (limited) synth or a full desktop/laptop. This looks like it supports it on an RPi, which is great! I'll have to look into this.

If I get it right this is digital effects controlled by analog controls. Whereas the holy grail of the audio world would be analog effects controlled digitally :)

The holy grail would be analog effects controlled digitally with a direct analog control layer. Wesausio would be an example for this [1]

It’s a Linux distribution with real-time kernel. Here’s a download link if anybody is interested: https://github.com/elk-audio/elk-pi/releases

what is a real time kernel vs a normal kernel? just "faster"?

Real time offers predictability. In some contexts being certain of a 3ms latency is better than going randomly from 1 to 4ms which could make the code faster on the average but with less predictable timings.

One that has no such drivers? Which would then imply limited hardware support as the price for the guarantee, which is a trade-off a general purpose kernel like Linux isn't going to make.

> Working with our 5G partner Ericsson, Elk will open up completely new products and network services to connect musicians and equipment remotely over the internet in real time. This seems difficult. What is the 5G latency chain like in practice?

My guess is that they don’t mean audio.

I think they do - 5G seems to have the prospect of some realtime low latency guarantee features (though I don’t think it’s rolled out yet). With this in place and an RT audio device you could build an all in one remote jamming box without having to insist on wired internet or deal with the wifi jitter. Currently the user’s network is often the bane of things like Jamulus that try to do this in software + your internet connection
