So you have ampache-3.4.4-0ubuntu1 installed and you want to give 3.5x a try, but wait 3.5 is not in the archives yet? Or better yet, you have PHP-5.2.6-0ubuntu1 installed and a newer version of PHP has come out and you want it now and not 6 months from now when the next release of Ubuntu comes out. Well the nice people at Debian/Ubuntu have developed a couple of tools to help you out. uscan and uupdate, which are part of the devscripts package, will help you update ANY Ubuntu/Debian package that has a watch file.

The first thing we need to do is install some needed packages.

wget {URL OF NEW UPSTREAM SOURCE TAR.GZ}

sudo apt-get install devscripts
sudo apt-get build-dep {PACKAGENAME}
sudo apt-get source {PACKAGENAME}

cd {PACKAGESOURCE-DIR}
uupdate ../{NEW UPSTREAM SOURCE TAR.GZ} -v {NEW UPSTREAM VERSION}

For awhile now, each time I got a new Windows laptop I would dig up strasis gist on how to set up agent forwarding for SSH in WSL2 -- but recently I tried to point someone else at it and they were very confused by it, so this is my attempt at simpler instructions.

Installation

With Chocolatey, you must use an elevated PowerShell session. If there's no choco command found, it will fall back to winget for the npiperelay install. To force using Winget even if you have choco installed, you need to download it, so you can pass parameters to it.

Easy mode: just run this in PowerShell:

Docker compose as a systemd unit

Create file /etc/systemd/system/[email protected]. SystemD calling binaries using an absolute path. In my case is prefixed by /usr/local/bin, you should use paths specific for your environment.

[Unit]
Description=%i service with docker compose
PartOf=docker.service

Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:
