Last week I shared a link to a post about which data is processed when you verify your identity with Linkedin. A friend got in touch and noted that this post and in fact the entire site seems like it was written by AI to him. He pointed me to GPTZero, an AI detector and indeed according to this the post was likely written by AI. Now that doesn't mean that the content of the post is not valid; maybe the author is just not a good writer and decided to let an LLM brush up his writing. Or do the writing for him. Who knows. What I find interesting is that the post didn't feel AI generated to me at all, which tells me that I'm not very good at recognising these things unless they're blatantly obvious. And also that there's a lot of grey area between "written by a human" and "fully AI generated slop". If I did all the research, wrote a draft for a post and then ran it through an AI writing assistant to make it sound more "professional" (in very big quotes), an AI detector would probably flag it, even though the content was still produced by a human. Ideally I would of course disclose to the reader to which extent AI was used, but most people probably don't do this, leaving us in the dark and guessing as to what we're reading is a person's writing or slop.

What am I taking away from this? I'm not going to link things here that are (to me) obviously AI generated. But I'm evidently not great at detecting what is and isn't AI generated (especially if it's written in English, which isn't my native language), and I don't want to be paranoid about it either, so things might slip through the cracks. I'm only human after all.

For what it's worth, I ran this text through GPTZero and it concluded that my writing is in fact 100% human. So that's good to know.

  • HTML & CSS Full Course - Beginner to Pro - YouTube
    I never really understood CSS, and so last week I set out to fix this and found this great online course. It's 6.5 hours long, so this is not something you casually watch, but the guy is an amazing teacher and I learned a ton from him. Highly recommended.

  • Here is why vim uses hjkl keys as arrow keys
    The fact that vi uses hjkl to move the cursor has always bothered me, because my fingers naturally rest on jkl and the key next to l (ö on a German keyboard) and I'd have to shift my hand over one key to use these keybindings, which I never liked. But now at least I know why it is like this.

It's CSS Naked Day

2026-04-09 08:00:00

Thanks to Zak I just learned that today (April 9th) is CSS Naked Day, a day to strip your website of it's CSS and show what it looks like underneath in plain HTML.

By sheer coincidence I worked a bit on making the HTML more readable without CSS yesterday. So this is what this site looks like without CSS. Not amazing, but still usable I think. I still would like it to look better, like a true 90s website. Maybe next year...

Right now as I'm writing this, humans are travelling to the moon for the first time within my lifetime. I'm not the biggest space nerd, but spaceflight and especially the Apollo moon program have always kind of fascinated me. And so I'm loosely following their journey to see how it's going and how far they've already gotten. Right now their distance from earth is around 91,700 km and ticking up by several kilometres every second. There are a few good websites where you can track the progress: Here, here and here (self hosted), which I've all found thanks to Dustin. And check out this great infographic from NASA.
The world feels increasingly insane and unhinged to me with all that's going on, and I'm glad that there are still things like this - great accomplishment made by many people working together for something rather than the destructiveness that I see everywhere else.

Emulating old OS X versions with QEMU

2026-03-29 08:00:00

I enjoy installing and playing around with old operating systems. Granted, I don't do much with them once I got them installed, but I like having a look around, checking out the integrated software and just seeing what it feels like to use this OS.

The other day I wondered if I could run the first versions of Apple's Mac OS X (back then for Power PC) in a virtual machine or an emulator. And it turned out that it's fairly easy to do with QEMU.

Software

QEMU is a virtualisation/emulation powerhouse which can emulate a ton of different architectures. It can be obtained here for the operating system of your choice. I'm on Linux, so everything that follows is geared towards setup on Linux, but I'm sure it can be easily adapted to other OSs.

Disk images for the old OS X versions are also needed, I got them from here.

Setup

I installed the available versions 10.0 through 10.3. The process was very similar each time, so I'm just going to describe it once here.

QEMU has no gui, so it must be configured via the command line. OS X needs the 32 bit Power PC emulator of QEMU which can be started with qemu-system-ppc.

First I needed a harddrive image.

qemu-img create -f qcow2 cheetah.qcow2 10G

This creates a harddrive image with a maximum size of 10GB called 'cheetah.qcow2'. It doesn't use up all 10GB to begin with, it grows with the amount of space that's used up inside, so it's fine to create a big one.

After some googling and trial and error I found a startup command for QEMU which allows me to boot an emulator with a working configuration. Here's the startup script:

#!/bin/bash

qemu-system-ppc -L pc-bios \
-name "Mac OS X Cheetah" \
-cpu G4 \
-smp 1,cores=1 \
-boot d \
-M mac99 \
-display gtk,gl=on \
-m 2048 \
-netdev user,id=mynet0 -device sungem,netdev=mynet0 \
-device ide-hd,bus=ide.1,drive=HardDrives \
-drive if=none,format=qcow2,media=disk,id=HardDrives,file=cheetah.qcow2,discard=unmap,detect-zeroes=unmap,detect-zeroes=unmap" \
-cdrom "Mac OS X 10.0 Cheetah.iso"

Running this will create a Power PC machine with the correct bios, an emulated G4 CPU with 1 core, 2GB of memory and the qcow2 harddisk image and the installation ISO attached. If you're having graphical issues, you might need to use some other display toolkit under the -display option.

Make note of the line '-boot d', this selects which device the machine boots from. At first we need to boot from the cdrom image, which is drive d, after the installation we need to switch this to '-boot c' to boot from the harddisk image instead.

I used this script for all four versions of OS X, obviously with a different harddisk image for each and the correct ISO file attached.

The emulator can then be started by running the script and it should boot right from the installation CD into the OS X installer. The installation is then mostly self explanatory and pretty much the same for every version. If you've installed MacOS before, you know what to expect.

A few notes:

  • Before the installation, the harddisk must be formatted. This can be done from the menu by selecting 'Disk Utility'.
  • On Cheetah (10.0), Disk Utility can only be started before starting the installation process. When you get to the drive selector screen and the harddisk doesn't show up because it isn't formatted, there is no way to start disk utility, so the installation has to be started over.
  • Make sure to deselect everything having to do with 'Classic Mode' or 'OS 9' mode or so, especially in Disk Utility on 10.3. Otherwise the installed OS might not boot.
  • After the installation when the OS asks for your address and phone number etc., this screen can be skipped by pressing 'CMD + q' (which on my Linux system is the windows key + q).
  • 10.3 comes on three disks. Installation is started from the first disk, after a reboot the machine needs to be booted from the harddisk (-boot c) and then it asks for the second disk. Disks can be swapped on the fly in the running emulator by going to the QEMU monitor with CTRL+ALT+2, running info block to get the label of the drive which the image is mounted in and then running change [drive-label] [/host/path/to/file.iso].
  • There is no sound. There is a fork of QEMU called 'Screamer' which adds audio to the ppc emulators, but it's a couple of years old and hasn't been updated since. Maybe the functionality got integrated into mainline QEMU by now? I couldn't find any reliable information about this, so for now, no sound. I might look into this later and update the post if I find out more about that.

The result

So, after an hour or two of installing these systems, which thankfully was very straight forward, I ended up with this:

Four freshly installed copies of the first four versions of OS X to explore.

It's weird, because I never used these systems back when they were new, and yet I feel somehow nostalgic for them. I don't know why, but there's just something about the look of them. The colour palette, the skeuomorphism, the fonts and the overall design are just beautiful, and I wouldn't mind using an OS with this kind of look and feel today.


Random thoughts

How many real Macs would you need to be able to run every modern MacOS version (everything 10.0 and after)? Let's see.

  • One G3 machine for the oldest PPC versions, so maybe an iBook G3 500MHz which will run 10.0 through 10.3.
  • One Core 2 Duo Intel Macbook/Mac Mini from 2006 which will run 10.4 through 10.7.
  • One i5 or i7 Macbook/Mac Mini from 2012 or 2013 which can run 10.7 (or 10.8) through 10.15.
  • One M1 Macbook/Mac Mini which runs 11.0 upwards.

Four machines for 25 years worth of operating systems, that's pretty good.

Too many computers for you? You can also just get an old HP desktop and Hackintosh the s*** out of it.

Made it to number 100! It's crazy to see that I've written 100 of these posts almost every week (I skipped one week in October 2024 and one in December, same year) for nearly two years. I've done some work on the site recently and you can now find a list of all previous linkdumps here, and everything from all linkdumps on one page over here. If you remember that you found something through one of my posts, but you don't remember which one it was in, you can just search on that page. I frequently grep through my old linkdumps, and this was also my original intention behind writing these posts: to get better at bookmarking interesting things, because I always sucked at it and things got lost. But now that online search is enshittified to the point of being nearly useless, having an archive of links you found interesting in the past and sharing them is as important as it used to be in the 90s before Google came along. Things seem to be coming full circle, and the worse Google gets (and it will get worse) the more important human curation becomes again.
