I bought during my visit in the museums a brick construction site and I recorded myself during the construction of my Brutus car 🙂

A small refreshed video for 2025 about creating a new personalised profile for PowerShell.

We visited Taunus Wunderland in Germany on 02/09/2024 and we got very disappointed. We even got stuck in a game (flight simulator) as most of the park is very very old (and just oh sorry for the longer wait for quiting the game pff...). The new part of the Parc has a great roller coaster but only for thin people - never had that issue in any other park. Also many things (shops, games, etc) were closed and no ambient audio. As the school in Germany already started when we went to the park not many people were present and so no waiting time...

PS: after reviewing the video I saw that portrait photos didn‘t take over the effects of my landscape photos very well and so got to much cropped - for the next video I now know it and won‘t do the same mistake

Here the link to the park on my project Parcum

In resume: DON'T WASTE YOUR MONEY ON THIS PARC - THEY EVEN LET REMOVE GOOGLE RATINGS IF THEY ARE BAD

We visited Mainz (Germany) on 01.09.2024.

Here are some impressions of our visit without interrupting bla bla bla.

In general we can say: A city to visit - it's simply great.

On 01.09.2025 we went on a day trip to Blankenberge and Brugge. Here are our photos from there (so also some photos from us are included).

On 07.09.2025 we went on a day trip to check the Technology Museums in Sinsheim and Speyer (Germany) and here are our photos (without filtering out the photos where we are present on it).

Most of the time you can find devices with IP65 certified but also sometimes there is a letter at the end.

In case of a data breach, ransomware attack or similar there are some steps to follow

Step 1

A cyber attack can certainly be classified as a disaster scenario and a clear mind is needed to navigate to a solution. Oncey you and your team adopt a problem solving attitude you will be able to respond to the breach in a logical and organized way.

The main point is "DON'T PANIC"

Step 2

If a cyber attacker demands a ransom it may be tempting and easier to pay it to regain control of your network but oftem times it may lead to future attacks so "DO NOT PAY A RANSOM".

I would say just pay a ransom if there is no other way to recovery your data but if you don't have any secured backup I have no pity for you!

You could also invest in an Endpoint Detection and Response solution that can stop ransomware before it can be executed.

Step 3

Now it's time to form a response team as to address any damage caused by the cyber attack you will need a capable and experienced response team. You team should be comprised of IT staff members either contracted or in-house who will investigate the attack and work to resolve it.

HR should be included if your employees haved been impacted by the attack. Public Relations representatives should be included to best explain the attack to your customers. Always includ legal counsel since breaches can have a number of legal implications.

Step 4

So let's see your backup which is hopefully available and undamaged from the attack (that is why offline backups are often very important). If this is the case switch to them immediately. The biggest reason this step fails is because it is often forgoten to test the data restoration process.

If you don't have any backup solution like I wrote I have no pity for you! Avoid switching off all your servers and workstations even if it's a good temptation but this won't stop or fix your damage.

Step 5

If your organization is hit with a cyber breach, it is imperative that you minimize the number of affected systems. You will need to isolate where the breach occurred and stop it from infecting other systems. Once the breach has been suspended you response team can test other portions of the network to see if they have been compromised as well.

Step 6

Now it is time to investigate. Upon investigation you may find that the damage affects numerous portions of your organization. HR response team members will need to be address any impact on your employees. If your customers or the public were affected PR staff will need to control the damage done to your reputation. The attack may even cause legal ramifications and as such your business's lawyers may need to be involved.

Step 7

After all that you should also contact your clients. The PR memebrs on your response team need to reach out to call clients who have been impacted by the breach as soon as possible. For security purposes your clients may need to change their passwords and/or PIN numbers if their private information was compromized.

Step 8

As your response team is investigating the attack ensure that they are documenting both their process and their findings. From this evidence you will be able to ascertain the vulnerability that allowed the attack to be successful and thus fortify it going forward.

Step 9

As last step I think it's sure that you are looking to prevent future attacks.

If your team is unable to effectively secure your organization's IT you may need to partner with an outside cyber security company. Outsourcing your cyber security needs to an Managed Security Services Provider (MSSP) can be cheaper and the are often more effective than most IT teams.

In IT there are so many authentication options. Here are the 10 commonly used ones.

We once had an issue to recover data from a broken disk. Under Windows the disk was directly "attacked" and so directly the control over it was lost.

Same was with Windows PE Boot Sticks to recover data.

So the only option left was Linux and here is how we did.

First you need some tools you can download from the links below:

http://www.system-rescue-cd.org/Download
https://rufus.ie or https://www.balena.io/etcher

1. Put the ISO on an USB Stick with Rufus (preferred) or Etcher
2. Boot from Stick (deactivate Secure Boot) without connecting any external device (makes it easier to find the correct devices later)
3. During the Boot process choose the default option (the first from the 2 options)
4. When the boot process is finished you may want to change your keyboard layout. You can do this with the setkmap tool.
   Simply type setkmap at the prompt and then choose your keyboard layout from the list (fr_CH as example) and click OK.
5. You can also start a graphical interface with startx but this is not needed to recover data. Within the graphical interface you can use FireFox, Partition Manager or FeatherPad (TextEditor)
6. Connect your source drive (the defective one) and search for this device with
   ls -la /dev/sdc (where sdc may vary depending on what dev your device was mapped – so it could be sdc / sdd / sde etc.)
   If you have chosen the wrong one you’ll get an error saying that no such file or directory was found.
   PS: With lsblk you should be able to see what disk is mounted under what /dev/

7. Now you can mount this device to check where the data is:

   • First create a folder in the mnt folder - do this with the following commands
     cd / (to get to the root folder)
     cd mnt (change directory to /mnt)
     mkdir source (take source as name as this is easier to find yourself back)

   
   

   • After creating the directory we can now mount the device (stay within the mnt folder)
     mount /dev/sdc2 ./source or mount /dev/sdc2 /mnt/source
     We use the number 2 as most of the time there are more partition created under Windows and 1 would be the hidden boot partition and 2 the first data partition
     That is also why we first mount the device to see if we are on the correct partition.

   
   

   • You can list what’s on your disk with (always while staying in mnt folder)
     ls -l ./source or ls -l /mnt/source

   
   

   • If you are on the wrong partition you have to unmount the device and restart with point b
     umount /mnt/source (for unmounting the source device)

   
   

   • if you can't mount due to an unclean NTFS file system you may try this (example):
     sudo ntfsfix /dev/sdc2
     sudo mount -o rw /dev/sdc2 /mnt/source

     
     

8. When you have your source device you connect your destination device to copy the data too. Important here is that you use a device formatted with NTFS as we are going to first create an image of the source disk on that disk which will be more than 4GB (FAT32 only supports files of max 4GB).
   Also here you have to do the same as for the source drive, just name the folder destination (point 7 and and as it is a NTFS partition the normal mount wouldn’t work so you have to take
   ntfs-3g to mount the device
   ntfs-3g /dev/sdd2 ./destination
9. When your destination disk is mounted switch to that folder so that you are in /mnt/destination
   This is important for the following command as we want to create a map file directly on that disk to be able to resume the recovery in case of a crash
10. For the recovery process we are going to use ddrescue. Here are some switches that may be needed:
    -f force
    -d direct disk access (slower but doesn’t use the kernel cache)
    with that method you can sometimes even recover more data as with the normal method
    not every system is supporting this
    -r3 retry 3 times (you can change the numer)
    -N skip the trimming phase
    We are using the following command for the first run (here we are recovering the most readable data)
    ddrescue -d /mnt/source /mnt/destination/data.img mapfile
    with that we copy the sdc2 partition in an data.img file on the destination disk and the mapfile is used if the recover crashes or so to not start from scrap.
    Also the mapfile is used for the second scan. Without switches we simply copy the data and when a sector has issues with reading ddrescue is skippin it and continuing with the next one without any retries.
    Now with the second scan we are going to use the -r switch to recover even more data. It is important to use the same mapfile as before
    ddrescue -d -r3 /mnt/source /mnt/destination/data.img mapfile
    You could also use this command directly but depending on the disk state you may lose all the data.
11. After the copy is finished (about 10 hours for 1TB disk) you have an entire img file of your source disk.
    Here you may want to copy it as when you are going to mount this file you are going to make changes on it.
12. Create an olddisk folder under /mnt
    mkdir olddisk (when you are under the mnt folder)
13. Now mount the image file an create the folder for the recovered data
    mount /mnt/destination/data.img /mnt/olddisk
    mkdir /mnt/destination/recovery
14. Than copy the data to the destination disk in a new folder
    cp -R /mnt/olddisk/ /mnt/destination/recovery/
    Pay attention that this also takes hours
15. When all the data is copied you can unmount all the devices
    umount /mnt/olddisk
    umount /mnt/destination
    umount /mnt/source
16. Now shutdown the computer
    shutdown -h now
17. Check on a Windows PC if you have access to the data

I hope this can help you if you ever have such an issue. I also had a personal SSD that wasn't accessible over Windows anymore but mounting it over an USB adapter on my Synology NAS, which is also Linux, helped me out and I could recover the data. It wasn't important data, as I have backups for everything, but I spend during some days collecting different download etc. for a project and so I didn't need to redownload everything lol 🙂 And there was an old Windows 95 game I patched to make it run on Windows 10 🙂

PS: If I ever make a video I gonna attach it - maybe you can leave a comment and tell me if you want a how to video from me.

If you ever had this question here is a link with the answer to it 😉

Synology DSM is actually based on a simple Linux system and therefore the standard commands can be used there. That's why you can easily get the IDs you will need for many containers thanks to the easy command named ID.

docker run -d --name=watchtower \
-v /volume1/docker/docker.sock:/var/run/docker.sock \
--restart=always \
containrrr/watchtower --cleanup --include-stopped --include-restarting --interval 21600

Watchtower updates your containers automatically without asking. For some, this is very useful, but for others who have to work with a container all the time, less so.

That's why there is also an option to always run Watchtower manually instead of automatically. You can find all of these options in the documentation.

Here is an example of a manual update of Calibre:

docker run --rm \
-v /volume1/docker/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--run-once calibre

docker run --rm creates the Watchtower container, runs it and when it is finished, it is automatically deleted.

Create symbolic link for docker.sock

ln -s /var/run/docker.sock /volume1/docker/docker.sock

I am creating this symbolic link because I was having problems with some containers accessing docker.sock. When I linked them like this, those containers no longer had any problems and ran perfectly.

your_spotify is a web app that shows you statistics about your Spotify usage.

You can find out more in the video.

The installation takes place in 3 steps:

• Database
• Server
• Web Client

docker run -d --name mongo \
-v /volume1/docker/your_spotify_db:/data/db \
--restart always \
mongo:4.4.13

With Synology you should be careful to use a 4.4.x version of the Mongo DB because 5.x is not compatible with the CPU of the device (maybe with newer devices this isn't the case anymore).

docker run -d --name=your_spotify_server \
--link mongo \
-p 33424:8080 \
-e API_ENDPOINT= https://dyndnsserverdomain/api  \
-e CLIENT_ENDPOINT= https://dyndnsserverdomain  \
-e SPOTIFY_PUBLIC=eurepublicid \
-e SPOTIFY_SECRET=eurepublicidsecret \
-e CORS=all \
--restart always \
yooooomi/your_spotify_server

ou must fill in the API and CLIENT endpoint according to your settings.

In the same way, you must take your Spotify PUBLIC and SECRET data from your developer account. Links to this are a little further down.

When filling in the data in the configuration on the Spotify page, it is important to fill in the correct redirect URI.

 https://dyndnsserverdomain/api/oauth/spotify/callback 

docker run -d --name=your_spotify_client \
-p 17812:3000 \

Please make sure to fill in your API endpoint correctly here too.

SWAG is a reverse proxy software based on NGINX. I tried to do the same with Traefik but I failed - even if it worked somehow, many pages simply had missing information and were therefore useless.
SWAG has a lot of ready-made configuration files for frequently used programs integrated and is therefore very easy to use.
You can also have SSL certificates created automatically by Let's Encrypt and fail2ban is also on board.

However, there is a big problem on a Synology, namely ports 80 and 443. Although the DSM software runs on a different port, these two ports were blocked and redirected.

To get around this, there is a small script that I am giving you here. This is run via an SSH session and unlocks ports 80 and 443 again.

There are a lot of instructions on the internet about this but I found a script on Github that worked for me - a lot of things hadn't worked before. As always, I put the link below in the list of used links.

CURRENT_BACKUP_DIR="$BACKUP_DIR/$DATE"

if [ "$BACKUP_FILES" == "true" ]; then
  mkdir -p "$CURRENT_BACKUP_DIR"
  cp /usr/syno/share/nginx/*.mustache "$CURRENT_BACKUP_DIR"
fi

if [ "$DELETE_OLD_BACKUPS" == "true" ]; then
  find "$BACKUP_DIR/" -type d -mtime +$KEEP_BACKUP_DAYS -exec rm -r {} \;
fi

sed -i "s/^\([ \t]\+listen[ \t]\+[]:[]*\)80\([^0-9]\)/\1$HTTP_PORT\2/" /usr/syno/share/nginx/*.mustache
sed -i "s/^\([ \t]\+listen[ \t]\+[]:[]*\)443\([^0-9]\)/\1$HTTPS_PORT\2/" /usr/syno/share/nginx/*.mustache

if which synoservicecfg; then
  synoservicecfg --restart nginx
else
  synosystemctl restart nginx
fi

echo "Made these changes:"

diff /usr/syno/share/nginx/ $CURRENT_BACKUP_DIR 2>&1 | tee $CURRENT_BACKUP_DIR/changes.log

To run the script, please change to the directory where you created it and run it as follows:

sudo ./free_ports.sh

Why this script? Well, as I said, it works, and above all it creates a backup of all changed files and tells you at the end what it has changed.

You can also decide which port should be used instead of 80 and 443 to then free them up.

It is best to save this script in a share under the name free_ports.sh, for example, and run it in an SSH session (don't forget sudo).

I use Bitvise, for example, as an SSH client under Windows - but there are countless others.

The script is supposed to always run at startup - but I haven't had to do that yet (my server restarts every day overnight - so it shuts down for 6 hours a night).
