I have a lot of old Power Point slide decks that I want to reuse in current presentations. By now however, I learned prepare all my presentation stuff in either Markdown or reStructuredText: far easier to publish and put under version control.
After searching, I could only find one tool that is still maintained doing a decent job doing a PowerPoint to Markdown conversion: [Wayback/Archive] GitHub – ssine/pptx2md: a pptx to markdown converter. The tools which works great, in big part of PowerPoint content being highly structured with styles like title, subtitle and various heading levels and content types.
The thing it does not document is the prerequisites, which are these:
- a
venv (which, despite having used Python quite often, but not proficient in it, still makes me nervous: one forgotten step and you pip everything in your global environment).This links helps me every time [Wayback/Archive] Install packages in a virtual environment using pip and venv – Python Packaging User Guide. From it, I created this little table:
Steps for setting up and using a Python virtual environment

Windows |

| 1. |
python3 -m venv .venv |
py -m venv .venv |
Only needed once |
| 2. |
source .venv/bin/activate |
.venv\Scripts\activate |
Switch to virtual environment |
| 3. |
which python |
where python |
Check if python is used from the virtual environment (should result in
.venv/bin/python on *n*x/MacOS or
.venv\Scripts\python on Windows) |
| 4. |
which pip |
where pip |
Check if pip is used from the virtual environment (should result in
.venv/bin/pip on *n*x/MacOS or
.venv\Scripts\pip on Windows) |
| 5. |

|
.venv\bin\pptx2md |
Force a module which didn’t add itself to the path when installed via pip |
| 6. |
deactivate |

Leave the virtual environment |

While migrating from iTunes on one machine to Apple Music on another one, I needed to migrate part of the (disorganised) playlists.
I knew there was a binary ~/Music/iTunes/iTunes Library.itl file, but that is encoded or encrypted, making it hard to parse.
Luckily there is also ~/Music/iTunes/iTunes Music Library.xml which I found via the links below.

Somehow this post missed the schedule and for a long time I forgot to properly checked for “missed schedule” posts.
Back in 2021, suddenly systems with speedtest-cli threw a [Wayback/Archive] ValueError: invalid literal for int() with base 10: ” by tzwickl · Pull Request #768 · sivel/speedtest-cli after accessing the speedtest.net servers.
Around 7-8 April, 2021 the speedtest.net/speedtest-config.php XML configuration suddenly had changed the value for the XPath expression /settings/server-config/@ignoreids from being a list of integers into empty, see the archived files below.
