Asus Zenbook UX3402 speakers on Linux

Important

THIS IS NOW OBSOLETE WITH KERNEL VERSIONS ≥ 6.7.0

A recent announcement in the kernel mail list by Cirrus developers will solve the problem described here. Therefore, the proposed solutions will be soon obsolete. See this comment (thanks, @flukejones, for the tip).

I got the speakers working on my Asus Zenbook 14 OLED UX3402, the one with Intel CPU and the two CS35L41 audio amplifiers connected over SPI (not the UM3402YA, with AMD and I²C). The amplifiers are supported by the snd_hda_scodec_cs35l41 module in recent kernel versions, but they require some model-specific configuration paramaters, that should be provided by

This document contains additional supporting material for the claims in this post (published 1 September 2019), in response to a cease and desist letter from John De Goes that I received on 6 July 2020.

Please see also this post for more information about De Goes deleting the FCoP repository on GitHub shortly before sending the cease and desist letter.

Deploying to Elastic Beanstalk via CircleCi 2.0

I got to here after spending hours trying to deploy to an Elastic Beanstalk instance via CircleCi 2.0 so I thought I'd write up what worked for me to hopefully help others. Shout out to RobertoSchneiders who's steps for getting it to work with CircleCi 1.0 were my starting point.

For the record, I'm not the most server-savvy of developers so there may be a better way of doing this.

It outputs a json-style tree of all towers/programs that are not balanced.

You need to get the value of the last tower that is unbalanced, but has no unbalanced sub-towers.

To get a good visualization do the following:

• Clone this repository
• Replace the file puzzle7.py with this version
• Run: $ ./aoc 7 2 -v

Using the input in the repo you'll get this output:

import scala.util.{Success, Failure}

val seq=Seq(Success(1), Failure(new Exception("bang")), Success(2))

// all emit         List(1, 2)

seq.map(_.toOption).flatten
seq.flatMap(_.toOption)
seq.filter(_.isSuccess).map(_.get)
seq.collect{case Success(x) => x}

We install certutil and pk12util if necessary:

sudo apt install libnss3-tools

On Linux, Chromium uses the NSS Shared DB. Check if you have the ~/.pki/nssdb directory:

ls $HOME/.pki/nssdb
