Tips on finding the correct modules to use?

I've been trying to begin a transition from NixOS to Guix, but I'm having a hard time finding where the different symbols referenced in the Guix/Guile manual are defined. For example, I want to use BTRFS on a LUKS-encrypted device, but I can't quite find what to #:use-module for the mapped-devices symbol. That is to say:

(file-system
  (device "/dev/mapper/cryptroot")
  (mount-point "/home")
  (type "btrfs")
  (options "subvol=home")
  (dependencies mapped-devices))

The mapped-devices above is an "unbound variable" (according to the errors). I still don't have this figured out, so how would others go about finding what to "import" since the official examples I'm looking at don't really tell me anything? (unless I'm blind, very likely!)

Advice on card draw in Orzhov?

Hello all, I'm a noob to magic building my first deck. I've been trying out this flicker deck with [[Syr Vondam, Sunstar Exemplar]] and I'm having okay results. It seems like I never draw my necessary cards to close the game out because I end up with no hand and am living paycheck to paycheck on my draw step. So I end up having an exile engine with nothing else, making it a real boring game for my friend and me. I think my deck is capable of playing both flicker and mini-Voltron with Syr Vondam at the helm, but I'm not sure what to start. Maybe I share the hate and just keep spam blinking [[Corrupt Court Official]].

Here's my decklist

Also, my friend was [[Fynn, the Fangbearer]], and I felt like I should've been able to get more creatures out on the board to stop the poison, but I was in a really passive position with one card in hand the whole time

Cover crops in potted container

Hello all,

I am growing in an organic medium. I'm somewhat new to growing still as this is only my second grow, first with organic soil. I was wondering how beneficial cover crops would be in my container. I was thinking on using white clover. Even if it isn't totally beneficial, as long as it wouldn't be harmful, it would be nice to keep that ecosystem active

the next question when the teacher calls on you while you're asleep and you answer correctly

The nth term of a geometric sequence can be written

a(n) = a(1)*r^(n-1)

We can rewrite the two given equations:

a(2) + a(4) = 30 = a(1)*r + a(1)*r^3 (Equation 1)
a(3) + a(5) = 15 = a(1)*r^2 + a(1)*r^4 (Equation 2)

Notice that Equation 1 can be substituted into Equation 2, i.e.,

a(1)*r^2 + a(1)*r^4 = 15
r*[a(1)*r + a(1)*r^3] = 15
r*(30) = 15
r = 1/2

If we substitute this into Equation 1, we have

a(1)/2 + a(1)/8 = 30
a(1) = 30 * 8/5 = 48

The answer is 48. Did he even need to specify that the sum exists? It's a finite geometric sequence so surely it's impossible for the sum not to exist? If you want to stop me old man, ask me the most basic combinatorics question you can think of and I'll start foaming at the mouth.

Thanks for verifying my answer, Elpam!

Thoughts on the Vestratto Tornado?

Hey everyone,

I've been seeing the Tornado mentioned in various places and wanted to ask for your opinions. Are any of you thinking of copping one?

Analog devices are very attractive to me. While I like the fact that devices like the UniDyn look like a tiny stick, I am a huge proponent for overengineered functionality than aesthetic (to an extent!)

What's a badass quote you've read?

Recently I was rereading SSS-Class Suicide Hunter and got to read this again:

Whether I looked up at the sky or walked beneath it, I was alone. Baraya. Baraya. Agabaraya. The world is winter, and a lone candle burns. If I sing, it is the song of the whole world, and if I die, it is the death of everything. It’s white. It’s turning white, and whiter still. - So Baekhyang, the Heavenly Demon
