• get a download link
  • audio=$(youtube-dl -f 140 -g "$utlink")
• use audio download link in ffmpeg to download portion of the audio

How to replace Kenmore electric range control board 8524212 (range model 665.95142300)

It took me awhile to figure how to remove the control board to either replace or repair it. Someone else showed me how.

To remove the control board:

• disconnect the clock / buttons panel connector
• disconnect all of the wires from the control board (mark them before disconnecting)
• if the board needs to be replaced there is no choice obviously

Advantages of using merge instead of squash

• If there are commits that logically address separate issues it's easier to understand such changes as individual commits in the history rather than squashed result
• Ability to check if the commits from other branches have been merged to main (using git branch -r --no-merge) which is especially useful for release/* deployment strategies
• If a file was first renamed and then modified in more than one commit (recommended approach for git to retain history), if these commits are merged then the history is retained. Otherwise, if squashed, git might consider the rename and update as old file deletion and new file addition (depending of the percentage of the changes).

However, there is definitely a case for squashing PRs when individual commits do not provide extra value and just create more "noise".

Things I don't like about java records

• record is final so it
  • can't be used in inheritance
  • can't be mocked in unit tests
• doesn't support builder pattern and as the number of fields grows Lombok's @Builder becomes preferable
  • although it seems to be possible to use Lombok's @Builder with java record
• Getter / setter name name() vs getName()

I don't see any major advantages with using record other than its immutable nature.
