When I record a mono source through the line in of my Ableton Move, I end up with the sample only in the left channel. Is there a way to record a mono sample, or to have the sample duplicated on both channels?

I'm trying out Emacs 30, but still have Emacs 29 on some of my computers. In order to use the new :vc keyword in use-package, I've put the following in my init:

(when (version<= "30" emacs-version)
    
        (use-package typst-ts-mode
        
        :vc (:url "https://codeberg.org/meow\_king/typst-ts-mode"))
        
        )

I was expecting the when-expression to ensure that Emacs only looks at the code inside if it's version 30 or higher, but when I open Emacs 29 I get this error message: ⛔ Error (use-package): Failed to parse package typst-ts-mode: use-package: Unrecognized keyword: :vc

Why does Emacs 29 know about that piece of code, and how can I make it forget?

I'm reading In Search of Lost Time, and really enjoying it. But I'm a slow reader, I have terrible memory, and I've been taking breaks (I started three years ago, and I'm now at the beginning of "The Guermantes Way").

This leads to me often being confused about who a character is, or about what's happened earlier. My edition (Everyman's Library) has very short summaries at the end of each volume, but they're not enough sometimes. I've only been able to find plot summaries online for Swann's Way, but none of the later volumes.

So my question is: do you have recommendations for where I can find brief plot and character summaries to refresh my memory while reading? Either websites or books w

I've just bought a DE razor and brush. I've been using the shaving cream from Recipe for Men (Swedish company) for a while, but I'm not able to get a good lather going. Does anyone have experience with this product - do I just have to work on my technique, or is it not possible to whip up a lather with it?

Dexter Gordon's "Three O'Clock in the Morning" (from Go!) and Miles Davis' "If I Were a Bell" (from Relaxin') both start with the same short melodic phrase.

I recognize this phrase very well, but I can't put my finger on where from. I have a vague feeling it might be used in PA systems at airports or something similar. Does anyone know the origin of this phrase?

I'm trying to flatten some thin (~10 mm, or 3/8") alder boards, and I've run into a problem: the boards have some cupping, so I start working on the convex face. But when I try to plane down the higher part in the middle, the boards flex from the pressure so that I can't get rid of the cup, no matter how much work I do.

Does anyone have any advice? I'm starting to think it was a mistake to resaw before flattening, but on the other hand I would think this situation could arise anyway, due to the wood moving after resawing.

I'm building the RE-606 (clone of the TR-606), and I accidentally got some bipolar electrolytic capacitors, even though the BOM specifies polarized caps.

Can I use these as long as they have the correct specification, or should I get polarized caps?

I'm probably missing something completely obvious here, but I can't figure out how to set the levels of each separate channel in the output from, e.g., [mc.cycle~]. I've tried [mc.sig~] into [mc.*], but not matter what message I give to [mc.sig] it seems to multiply all channels by the same factor.

Is there some other object I should use for this, or am I patching things wrong?

I just got a Canyon Endurance AL 8.0, and this metal ring (around 4 cm in diameter) was in the package. I can't figure out what it's for - does anyone know?

This is driving me crazy - I'm soldering 0603 components to an MI Veils board with tiny pads, and some of the pads refuse to take solder. Once I get some solder on them, it's almost impossible to melt it with my iron. The resulting joints look like cold joints. This happens with specific pads, so it's not bad technique for those specific joints. What's going on?

I'm building an Ornament+Crime eurorack module, and the SMD soldering has been mostly fine, except for the DAC chip which has very closely spaced legs. I tried drag soldering it with a chisel tip, but that resulted in several solder bridges between the legs. I attempted to remove the bridges using a desoldering wick, but no luck. The bridges were a bit up the legs, close to the chip itself.

In the end I managed to remove the chip, and since I figure there's a decent chance I fried it in my attempts to remove it, I've ordered a replacement.

Now I'm looking for advice: how do I make sure the same thing doesn't happen again? I'm using a flux pen and a soldering station, and dragging has worke

I've started building eurorack modules from kits. I've done a couple of the Music Thing kits, and once I got the hang of it the soldering has been going great.

However, today I did a kit from Random Source (Serge Ring), and had huge problems getting the solder to stick to the pads. It was as if the pads were repelling the solder. After some trial and error, I found that if I heat the pad and wire a bit longer (3-4 seconds) with the iron before adding the solder, it flows nicely for maybe 2/3 of the joints - but for the rest it still refuses to flow to the pad!

The Random Source PCB has gold-colored pads, while the Music Thing PCBs have had silver-colored pads - could this make a differen
