10 days on a Mac

For those of you who know me, you guys know that I am a Linux lover. I switched to Ubuntu completely a few years ago, for work and for personal computer use, wherever I could. Yes, there is still a Windows VM in the house, but that gets rarely booted and only for some special usage patterns like Tax declarations or update of my Logitech Harmony. Pretty much everything else is Linux, including a set of Raspberry PI’s.

Now, a few weeks ago, a colleage offered me to get me a Mac. As you might know I work for IBM and IBM gives employees a choice these days to either get a Windows machine or a Macbook Pro. Standard Model is a 13” machine, but as I got some capital approved, I was able to order the machine I wanted. So I decided for the 15” machine to get some more power for certain tasks that I am doing from time to time.

Having said all that, I was really thinking about it in the beginning if I would be ready to try a Mac. Honestly, I am pretty happy with Linux, it does (most of the times) what I need it to do and it is fast. The only really issue over the last weeks was a virtual machine that took me in the end more than 5 minutes to boot up. It even felt more like 10 minutes before I was able to get some work done on the machine. Sure, that was due to the i5 and only 8GB memory on my thinkpad, nevertheless, it was annoying.
The other thing was that the support of Linux as a desktop OS is mostly an issue. Most apps which are not native web apps often only work through workarounds, you can get them working, but it takes one thing especially: time and patience.

So again, when the offer was made to get the Macbook, I said “ok, I’ll try”.

The machine arrived last Wednesday. Of course unboxing is great, the machine has a nice look and feel.
So I got it hooked up and started it. To make a long story short, the setup was easy, IBM provides good tools to setup the machine and get it configured. The only bad thing I experienced was the fact that I could at certain points not fugure out if the machine was hanging or still doing something as there is no indicator of HDD activity. That still feels weird.

So, after the setup of the tools IBM provides, the next step was getting some tools that I used on my Linux machine. To my great surprise, a lot of those are available. So I started to download the main tools and hit the first roadblock. A lot of the freeware packages were not signed by the developer and IBM had set the security to not allow installation of those packages. Google helped to solve that problem and up to now there is only one package I could not get installed – and that is not a terrible thing as MacOS has the functionality already build in.

Talking about MacOS, that was the other thing I was really worried about. My biggest worry was that it would limit me to much coming from Linux. But after a week into it, I think if you know what you need to do, MacOS let’s you do it. For example, I was missing my music and picture folders, easy access to my home folder and the ability to spread things our in my home directory. There were enought tutorials available to get going and now, more than a week into using the Mac I feel ok.
This morning I even got the mounting of my nfs shares done, so I am hooked up into my home network almost like I was on linux, with a few more things that I still need to fix. But there is no major hurdle.

The handling overall is different, but not bad. Having been a user of Unity on Ubuntu, the switch felt easy to MacOS as concepts are pretty similar overall. But the keyboard shortcuts are different, so is the keyboard. Yesterday for example, when writing emails, I constantly closed Thunderbird by mistake as
1) the @ sign on the German keyboard is on the Q
2) and Alt-GR on Linux is at the same locationan on the Windows keyboard as the Command key on the Mac – so I was constantly hitting Command-Q
But as I am mostly using keyboard shortcuts anyway – old habit – I was pretty quickly getting my handle on MacOS.

The other thing I am finding weird is that you have to specifically close an app on the Mac. That remains weird, as I try to keep my desktop Clean and really get things shut down. But again, if you are rather using the keyboard than the mouse, it’s not a real issue.

So – what’s the net here. I am surprised how smooth the switch to Mac was for me. I can work productive with it and I have not really used my other Laptop (except for copying data from it to the mac) in a week. I get things done on the Mac. And I feel I can get it to where I need it to be.

Last, but not least, the real WOW moment I had after I had migrated the virtual machine I was talking about earlier to the Mac. It took a while (80GB of disk at this point) – but the machine boots in the mac in about 10 seconds, compared to almost 10 minutes before. That clearly is a gain of productivity, as well as the ability to use tools I need of the shelf and natively install them on the Mac.

So – will keep you posted how I progress.

Was ist ein guter Vater?

Meine Frau hatte mich vor einigen Wochen darauf angesprochen, bzw vorgeschlagen, bei einem Interview zum Thema “moderne Väter” für eine lokale Zeitschrift mitzumachen. Zunächst fand ich den Vorschlag reizvoll und interessant, aber kurz vor dem ersten Termin gab es einige kleinere Probleme, die mich an der Qualifikation zu diesem Thema doch haben zweifeln lassen, da ich mich in genau diesem Moment eben nicht als guter Vater gefühlt habe.

Ich kann mich heute nicht mehr genau an die “Probleme” erinnern, aber es war etwas, wo wir als Eltern die üblichen Meinungsverschiedenheiten zur Erziehung unserer Tochter hatten, bzw das eine oder andere, was ich getan habe, von meiner Frau als nicht richtig gesehen wurde. Letztlich kam dann auch noch einiges an unprofessionellem Verhalten seitens des Verlages dazu (eMail vom Fotografen an alle Väter mit sichtbaren eMail Adressen), so dass ich dann letztlich abgesagt habe.

Heute habe ich dann den Artikel gelesen – und bin ehrlich gesagt froh darüber, dort nicht vertreten zu sein. Warum?Nun, zum einen erscheint mir der eigentliche Artikel sehr oberflächlich.

Es geht im wesentlichen um generelle Probleme, Literatur zu dem Thema.

Es geht aber vor allem um eines nicht: DIE VÄTER.

Das fand ich schon etwas komisch.

Die Väter selber kommen nur in kurzen Textabschnitten zu Wort. Und auch diese sind in meinem Empfinden eher belanglos bzgl Ihres Inhaltes. Die Varianz reicht von: Ich arbeite nur noch 100%, um für meine Kinder da zu sein, über: Mir ist es wichtig, gemeinsam zu essen bis hin zu “was soll das ganze Thema eigentlich, ich gehe arbeiten, meine Frau ist zuhause. Alles gut”. Informationsgehalt geht für mich wirklich gegen Null, es fühlt sich an, als müsse hier etwas bearbeitet werden, dass sich entweder nicht bearbeiten lässt oder das gar nicht richtig durchdrungen werden soll.

Letztlich ist das Thema sicherlich sehr interessant, denn es stellen sich natürlich mal mindestens 2 Fragen:1) Was ist eigentlich ein guter Vater?2) Wie lässt sich das “guter Vater” sein mit dem Alltag vereinbaren Grundsätzlich denke ich, dass ein Guter Vater zu sein immer eine sehr persönliche Einschätzung ist, denn letztlich gibt es hier genau einen Personenkreis, der qualifiziert ist, hier ein Urteil zu fällen: die eigene Familie!

Ich kann aus eigener Erfahrung sagen, dass wir hier immer wieder über unsere eigenen Rollen reflektieren, Probleme besprechen und versuchen, an uns zu arbeiten, unser Kind zu unterstützen und zu führen, Ihm Räume zu schaffen, sich zu entwickeln und sich zu entfalten. Es ist ein kontinuierlicher Prozess, wir sind nicht immer einer Meinung, aber ich denke, wir sind insgesamt gute Eltern. Somit sind wir wohl auch eine gute Mutter, bzw ein guter Vater. Auch wenn es natürlich immer wieder Ausreißer gibt und das nicht jeder in der Familie zu jeder Sekunde so empfindet.

Die eigentlich interessante Frage ist allerdings, was ist das Wertesystem eines guten Vaters. Auch das ist ganz sicher sehr persönlich. Und hier treffen eben Sichtweisen aufeinander. Als Vater ist einem sicherlich wichtig, für die Familie sorgen zu können, auch finanziell. Als Mutter ist es einem wichtig, dass der Vater aktiv am Familienleben und der Kindererziehung teilnimmt. Als Kind ist es vielleicht noch am einfachsten. Da ist es wichtig, dass man Aufmerksamkeit und Liebe bekommt. Dass man ernst genommen wird.

Als jemand, der nicht sagen kann, dass er eine gute Kindheit hatte und die Eltern, die er sich gewünscht hat, versuche ich, viele Dinge anders zu machen als mein eigener Vater. Ich versuchen explizit Zeit für mein Kind zu schaffen. Ich versuche neben all meinen persönlichen Bedürfnissen auch denen der Familie nachzukommen. Das ist natürlich nicht immer einfach, ein stetiges Abwägen von Dingen. Aber es gehört dazu. Das gleich gilt auch für den Spagat zwischen Job (materielle Absicherung) und Zeit für die Familie (emotionale Absicherung). Ich empfinde dies als stetigen Kampf zwischen beiden Sachen, denn beides vernünftig parallel nebeneinander hinzubekommen, ist nahezu unmöglich!

Und ich fühle mich da selber auch sehr oft zerrissen.

Inzwischen bin ich auch schon mitten in der zweiten Frage: Wie kann ich meine Vaterrolle mit dem Alltag vereinbaren. Wahrscheinlich geht das nur, wenn ich jedes Mal überlegen, wie ich welche Prioritäten gerade setzen muss. Was ist gerade wichtiger? Der Chef, ein wichtiger Deal oder eine Aktivität mit der Familie. Um das etwas einfacher zu gestalten, versuche ich mit an Tag und Tageszeit zu orientieren. An Werktagen zu normalen Arbeitszeiten geht meistens der Job vor, ansonsten versuche ich, der Familie und gemeinsamer Zeit mehr Priorität einzuräumen. Das ganze ist natürlich nicht schwarz-weiß, auch nicht grau: Es gibt ganz viel Farbe zwischen schwarz und weiß.

Letztlich zählt nur eins, dass der Mix aus all diesen Dingen für die wichtigen Personen im Leben – der Familie – ok ist. Aber da sich alles immer wieder ändert, hilft es letztlich nur, das ganze immer wieder zu reflektieren und vor allem auch von allen Seiten offen über eigene Bedürfnisse zu reden, auch über Dinge, die nicht gut gelaufen sind. Und daran zu arbeiten.

Wir alle ändern uns permanent, entwickeln uns. Und ich denke, eines ist wahrscheinlich eindeutig. Ein guter Vater zu sein ist immer eine Betrachtung einer Situation. Ich kann jetzt ein guter Vater sein, in 5 min bin ich es dann vielleicht genau nicht.

Von daher denke ich, dass mein Schluss hier ist, neben der Tatsache, nicht bei dem Artikel mitgemacht zu haben, dass wir alle, die wir Väter sind, das in jedem Moment sind, dass wir in jeder Situation Entscheidungen treffen müssen. Und genau diese sollten wir versuchen, bewusst zu treffen. Entscheide ich mich gerade für den Job oder die Familie? Am besten haben wir einen Grund für die Entscheidung. Ich kann für mich sagen, ich fahre damit ziemlich gut, mir gegenüber. Ich versuche Entscheidungen bewusst zu treffen, wenn ich muss. Dann habe ich für mich und andere eine klare Kante. Und damit lässt sich meistens besser umgehen, als wenn eine Entscheidung nicht nachvollziehbar ist für andere. Es macht nichts besser. Aber ich denke, dass mein Kind dann weiß, woran es ist, warum ich gerad etwas nicht tun kann, was es möchte. Meine Erfahrung bisher ist, dass das gut funktioniert.

Und vielleicht ist das auch ein wichtiger Teil davon, ein guter Vater zu sein: Gut mit dem Kind und der Partnerin zu kommunizieren.

fixing a long term Ubuntu boot issue

I am an Ubuntu user – for years. For work and personal use. But lately I was struggling with my Thinkpad T530 during boot. It would just freeze during boot process. After I had to do an emergency update 2 weeks ago the issue went from “happens twice a week” to “happens every boot”, with me trying to boot the machine several times yesterday before it would come up. So I took a few minutes yesterday to write down the error messages, read blogs and look for a solution.

What became obvious was that it was related to ACPI – power management and the Laptop screen. I had seen the machine hanging during boot there multiple times but only yesterday I really digged into the issue. Lenovo Thinkpads (amongst a few others) have specific ACPI settings and packages – which seem to be part of the V4 kernel these days (at least no additional packages). I think I am running a configuration which is not really common as I think most other users are not experiencing issues.
Anyway, to make a long story short, I found this article yesterday. It gave me the right hint as the issue was related to the Backlight of my LCD (that was the error message during boot). So I followed the suggestions and tweaked /etc/default/grub from

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”

to

GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash thinkpad-acpi.brightness_enable=1 acpi_backlight=vendor”

after this change, you need to update Grub by running

sudo update-grub

to write the changes to your actual Grub config. Now for a few boots the machine das what it is supposed to to – it simply boots. Good achievement before moving to vacation later today 🙂
P.S.: To be honest, I only partly wanted to blog about this 😉 What I mostly wanted was to make a note somewhere so I could find it when needed 🙂

Kodi reinstallation

Today I did setup a Raspberry Pi 3 to replace my very old- single core Raspberry that was running XBMC first, later Kodi, a freeware Media center player. So if people are looking to get a simple, just working media center player that can connect to NFS shares, Windows (SMB) shares and can also stream from the Internet and support DLNA as well as Airplay – here you go (assuming of course you are not afraid of a Linux commandshell, if so, use a Windows PC 🙂 )

The setup of the PI (4th one in our house) was nothing but a breeze. Downloaded Raspbian, followed the install instructions. Then the Raspby is pretty much up and running, you only need to run the raspi-config command to grow the file system and setup a few other things.
Installing kodi is simple “sudo apt-get install kodi” – to get it started automatically, set the autostart value in /etc/default/kodi to 1.
So far so good. But I had some issues getting video to work. Of course, I was missing the codes, but I don’t think that was the only problem. What was really missing is you have to give the gpu minimum 256 MB of RAM to work properly. This can be done with the raspi-config under advanced config and A3 Memory Split.

Now I was able to populate the media library and everything works like a charm. It is significantly faster in its response time than the old model. so the whole media player is now around 60€ – not really bad. To not keep more devices than I needed I retired an old netgear player immediately.

few thought (technical stuff this time)

I know I have been quite for a while. There are plenty of things to do at work and around work – but all good.

Recently I just started a really dumb thing: Upgrading my Laptop from Ubuntu 14.04 LTS to 16.04 LTS. That experience was not great, the machine froze in the middle of the upgrade process and did not start afterwards (only with the fall-back USB stick). I am still not sure what the issue was, but I found a few things to be really tricky after the upgrade as I was expecting a few hick-ups to get started again.
a) I absolutely HAD to disable the security chip on my thinkpad, otherwise Ubuntu won’t start.
b) I turned off UEFI
c) I keep having issues with USB – likely because of an external USB hub that has an external power supply. Removed the power supply, will see if that makes a difference (seems to be a known problem)
d) I had the issue discribed here with the mei module. Did blacklist it
e) I am also experiencing issues with NFS shares. I used to mount them during boot time from my QNAP NAS, but that seems to REALLY slow down the boot process significantly. Removed that for now
So far, so good, still a few more things to fix, but getting there. Luckily my company Thinkpad was the last machine to be upgraded. Of course timing was bad as I had to urgently work on a few things on a deal in parallel ….

The blog ain’t dead

I know, I have not posted for a while – again. Things are very busy currently for me on all ends. There are a few things I really wanted to blog about, but until now I have not really found time to do so. But I will get there.

Now that the first big event of the year is over (IBM Connect), I hope that things fall back into a descent order and the rush before the event moves back into normal madness. But I keep saying, after I was not sure (again) how IBM connect would be this year, I was pleased with the event and the new location. After it felt really weird not walking into the Dolphin but the Hilton Orlando this time, I really was used to the venue by Saturday. And of course, the event is about the people, it is not about the location. I guess most people came to this very same conclusion very quickly.
For me personally IBM Connect is becoming more and more busy every single year. Where I had some time on Sunday to talk to friends and Business partners, the rest of the week was almost completely booked with client and partner meetings. I barely got to see people during the event I wanted to see. But hey, it is work, the meetings is why I am at the event.
On the more personal side, I managed to had a few really good times, especially the penumbra dinner (as every single year) and the Australia Party. And I did not get a lot of sleep – also same thing as always. I think I made 25hrs in total during the whole 6 days …. And of course the thing that we all were concerned about, the bar closing at 11p did not happen. I remember us still sitting there at 1:30 a Tuesday morning with me noticing I better go to bed to be ready for my 8a client meeting (which then did not happen).
So, in summary, I do share the positive view on the event, although we had better guest speakers in previous years – but the conference is about IBM Collaboration Solutions, not the guest speakers.
One last notable thing was that I upgraded to premium economy for my flight as I had to spend miles – I think Lufthansa is achieving exactly what they want – they won’t loose one client from Business class. So, it was nice to have a little more leg room (food was exactly the same, we only had a personal bottle of water), so I am not entirely convinced it was worth 30k miles each way. But it was definitely a little more comfortable than regular economy. So if I had the opportunity to fly premium Economy, I would certainly do that again. It is definitely better on a 10 hr flight than regular economy.

back in motor cycles

There was one thing I moved away from some time ago – and back into earlier this year – which was riding a motorcycle.

Those who know me for a longer time know that I always owned a motorcycle and sold my Bandit 600 in 2008 as I had a different focus in life and also (more from a practical aspect) no ability to securely put it anyway. So when my father decided to sell his Honda CBR, I also made the decision to sell my bandit.
Honestly, I rarely missed it ever since, but in the more recent years I started to think about getting back into motor cycles more frequently again. I had a chance to buy an old Suzuki Intruder – which I always liked – but that did not work out. So when a good friend of mine offered my to ride his 35 yr old CX500C – I could not really resist. Honestly, the first few rides were feeling strange, I had to replace some gear as well. But after a few rides I really started to enjoy it again big time. It is really nice to be able to ride with friends on the weekend and have a good time.
But what I realized within a few month was that the CX500 was nice to get back into riding – but not a bike that I would really enjoy a lot. So I started to seriously think about getting something I would really enjoy again. To make a long story short – it ended to become a Honda Hornet finally, with a little more power than I originally wanted, but as it drives nicely and the insurance is more than reasonable, I could not resist.
So now, since a few weeks, I enjoy riding even more! And what a difference it is in the Odenwald area – the Hornet is a great bike for the area, it is keeping a nice speed on the curvy roads and has a good package in terms of security features. And – the most important thing to buy the hornet was – it was feeling right from the very first moment sitting on the bike, from the very first kilometer.

when the postman ….. makes a mistake

This is one of the typical things – that happen and should not.

I treated myself to a new Raspberry PI earlier this week and ordered from Amazon. As pretty much standard today, I could track the shipment on DHL’s page and saw that the packages was delivered due to DHL at an agreed upon place as I was not home…..
So coming home, I looked at that place – and my parcel was not there. So the search started. Neighbors said they had seen the postman at our place. Still, the parcel was missing and no-one around had picked it up for us. So, 2 options remained:
1) somebody had stolen it
2) there was something wrong in the delivery flow
Luckily I was able to catch the postman today – who we know for a few years now and who is a great guy. I asked him and he said, he could not remember putting anything down for us – but he did around the corner and said he would check to see if he made a mistake – 10 min later he delivered my parcel.
Obviously I could have gone through the official complaint process, but I though it would be much nicer to ask him before doing so -and that clarified the whole situation as he made a mistake. No big deal.
The whole story reminds me of one important lesson I learned: It is usually not a bad thing to talk to each other before going mad at somebody else. There was an easy solution to the problem, and often there is.

IT Security thoughts

It seems that this week a couple of IT Security related things are crossing the wire – so I really want to quickly share 3 of those to make my non-IT friends a little more sensitive about this topic…

I guess this all started with the news earlier this week that a hacker group has managed to inject code into the Firmware of Hard Disk drived – so basically the heart of what every computer uses to store data. This code can basically copy data to hidden parts of the drive and then establish a connect to upload the data. And there is no easy way get rid of this. The way to inject the code is basically build into the Disk Command specification and undocumented….. Here’s are 2 article on this, in German: Spiegel online and heise
To be really simple – once this SW is on your system, people have access to all your data!
The second things was the Lenovo incident yesterday- Lenovo had installed a tool on their laptops that basically can act as man in the middle to inject unwanted advertising into your search queries. Why is this important? Well, the ads are not really the problem – the problem is that all protected connections (for example to your homebanking) are not safe anymore. The advertising tool can decrypt the data, it is not the browser who does that. And that means that basically the ad Tool opens up the door for the misuse of data. Somebody can get your banking data – and with that your money. Even the Tan codes can be taken and sent. So you really want to monitor your banking account to see if your money transfers are correct.
The 3rd one is basically about people not configuring the environment correct. Again mentioned on Spiegel online, a student wrote a simple program that was checking if any file shares would be accessible. To explain, a file share is used to allow other computers to access a file – on computers, shared storages or other devices. Almost every computer has a fileshare, usually protected by passwords. The point of the article is that most of these shares either have no password set or very simple ones.
I don’t really know how this can be done easily, but it is easy to configure something and leave security asite as passwords are inconvenient for people. Nevertheless, no password means again everybody has access. Maybe it is worthwhile to either have tools from trusted sources that check security and help users to get it right or make better defaults.
There is even a 4th one now – Metadata tracking by our beloved smartphones. Go, check out where you have been over the last days and month.
If you are using an android phone, go here. Log in and take a look. All this google knows about YOU!
Do I want to scare anybody? Hell, no. But I am trying to explain these things in a way people can get sensitive. And think before they do things. I would say any company has one big interest – their own benefit.
I guess the first thing for everybody to do is read things on the screen – not every checkbox is good, like the one when installing Java that will also install the “Ask Toolbar”. Uncheck these things unless you really want them! So really consider if you need something installed on your computer – or not. And always use trusted sources for Software – and keep virus scanner and firewalls updated and current.
Not that they would really help against user errors – but they make it harder to cause damage!

Ubuntu and Unity – quick hints

As those of you who work with me on daily basis know, I moved all my machines to Linux, more specifically to Ubuntu a couple of years ago. And I am a happy camper – most of the days.

Last week I had one of these things where a colleague walked up and reported that he had lost the Unity desktop and had to work through Gnome – which is not a problem. 
I went through this myself a few times on earlier versions. Ubuntu just dropped Unity at some point which makes it fairly hard to do anything if you don’t get a menue or anything else on the Graphical shell.
The problem though is relatively simple by it’s nature. After some research I found out that Compiz had simply disabled the Unity plugin – renabling solves the problem.
Now, with a useless graphical environment, that’s hard. Sure, one can go through gnome, but it should go easier than that.
As usually you get at least the desktop and it’s Icons, my first solution was a simple exacutable bash script on my desktop to at least get to a terminal – from where I can launch ccsm (compiz config settings manager) and reenable the Unity plugin.
Last week, when I was helping the colleague, I had to drill deeper into this. It would be relatively easy to solve the problem if it was just a text based file where the entry need to be made – reality is that compiz now stores it’s settings as gconf settings – so no way to easily edit a text file from a command line.
After some research and some tries – also through the graphical GConf Editor – I found the solution (I guess) 🙂
The following command reads what we need from GConf:

gsettings get org.compiz.core:/org/compiz/profiles/Default/plugins/core/ active-plugins

if you have a problem with Unity, unityshell should not be listed there – so when you turn this around and do a set instead, copy and paste what you have and add unityshell as active plugin, this should do the trick for you. For me the commandline looks like this:

gsettings set org.compiz.core:/org/compiz/profiles/Default/plugins/core/ active-plugins “[‘core’, ‘composite’, ‘opengl’, ‘move’, ‘resize’, ‘place’, ‘wall’, ‘imgpng’, ‘regex’, ‘vpswitch’, ‘mousepoll’, ‘grid’, ‘compiztoolbox’, ‘session’, ‘wobbly’, ‘animation’, ‘expo’, ‘fade’, ‘workarounds’, ‘ezoom’, ‘scale’, ‘unityshell’, ‘switcher’]”


Now you can just take this and customize it – as a simple script (that I have now stored in my home directory), this is doing the magic to fix the problem now – even from a simple terminal….

#!/bin/sh
gsettings get org.compiz.core:/org/compiz/profiles/Default/plugins/core/ active-plugins
read -p “Resetting to my default [YeS/No] ” response
if [ $response = “YeS” ];
  then 
    gsettings set org.compiz.core:/org/compiz/profiles/Default/plugins/core/ active-plugins “[‘core’, ‘composite’, ‘opengl’, ‘move’, ‘resize’, ‘place’, ‘wall’, ‘imgpng’, ‘regex’, ‘vpswitch’, ‘mousepoll’, ‘grid’, ‘compiztoolbox’, ‘session’, ‘wobbly’, ‘animation’, ‘expo’, ‘fade’, ‘workarounds’, ‘ezoom’, ‘scale’, ‘unityshell’, ‘switcher’]”
  else
    echo “No harm done ! Exiting”;
  fi


I have build in some extra security as I know how carefully I read prompts – it makes it a little harder to overwrite something I don’t want to be overwritten…
Would be happy if this helps somebody on the next Unity failure – at a bare minimum this is now my own documentation 😉
