New Thinkpad Trackpoint Keyboard II

(i maybe should have cleaned it, before the picture…)

I got my first Thinkpad Trackpoint keyboard as a farwell gift from a company I worked for (thanks <3 ).
I don’t use any mouse, I just use the red “joystick” (called trackpoint) to navigate. For users which aren’t used to it, it’s a horror if they have to use my keyboard. But if you are used to it, you don’t wanna work without it anymore.
As you can see, the old one is not in a good shape anymore. And as working-from-home is the new normal, the company I work for, offers us the equipment we need, so I ordered a new one.
This is a newer version, which is running without a cable but wirelesse with an USB dongle. So far so good.

the setup

This is how my setup looks like:

as webcam I use a Waveshare 10300 RPi Camera (E)
(bought it here, unpaid advertisement)

Install raspberry pi image

Download the images from the raspberry pi website
copy it to your sd card.
on the webpage they recommend to install the rpi-manager via sudo apt install rpi-imager, but for me it wasn’t working because of dependency problems.
So I installed it the classic way:

First build an docker container and run it afterwards so you see it with docker ps -a As an example, I use the container for the MagpiDownloader

docker build -f Dockerfile . -t mag-pi-downloader
docker run -v $(pwd)/issues:/app/issues/ mag-pi-downloader -f 131

After that is done, have a look, for all the docker container:

$ docker ps -a
CONTAINER ID   IMAGE               COMMAND                  CREATED              STATUS                          PORTS     NAMES
ea901f38e328   mag-pi-downloader   "/bin/sh /app/entryp…"   About a minute ago   Exited (0) About a minute ago             exciting_feistel

As you can see the newest has the container id ea901f38e328

Lets say you have a User model with Lombok modelwide @Getter and @Setter:

@Getter
@Setter
public class User {

    @Id
    private String id;

    private String username;

    private String email;

    private String password;
}

setId(String id) makes no sense.
Normally the id is set by the DB, so it makes no sense to set it.

So you can use @Setter(AccessLevel.NONE) (or @Getter(AccessLevel.NONE)) to exclude it from the Lombok setters (or getters)

@Getter
@Setter
public class User {

    @Id
    @Setter(AccessLevel.NONE)
    private String id;

    private String username;

    private String email;

    private String password;
}

(I found this answer on Stackoverflow by user Michael Piefel for this problem, thanks!

• Facebook Container from Mozilla
  “Facebook Container isolates your Facebook activity from the rest of your web activity in order to prevent Facebook from tracking you outside of the Facebook website via third party cookies.” (from the Github description)

• Dark-Reader from Alexander Shutau (also available for other browsers)
  so join the dark side for a nicer reading

• HTTPS everywhere by EFF and Tor Project (also available for other browsers)
  “Many sites on the web offer some limited support for encryption over HTTPS, but make it difficult to use. For instance, they may default to unencrypted HTTP, or fill encrypted pages with links that go back to the unencrypted site. The HTTPS Everywhere extension fixes these problems by using clever technology to rewrite requests to these sites to HTTPS” (description from the website)

As I was always a LucasArts fan in the 90ties, I wanted to use my “free time” (thanks to the Corona lockdown) for playing this old classics.

I bought Monkey Island 1 + 2 on Steam - with the Proton helper, it starts all easy, out of the box.

Monkey Island 3 and 4 I was buying at Gog (it was cheaper) - no help here to get it running for Linux. (it will still run from Steam out of the box, afaik)

If you destroyed somehow your Linux system, which has an encrypted volume, and you want to log into this, but booting is not working, boot from a live ISO, and type:

lsblk -f

you will see sda1 oder sdb1 as your encrypted system

this decrypt it and mount it (for example sda1)

sudo cryptsetup luksOpen /dev/sda1 crypted_sda1
Enter passphrase for /dev/sda1:

after entering the passphrase you can see that this is now decrypted

When you create a new file directly on Github and push it to your branch, you will see in the commit, that this was done by an verified user.

If you push it from your command line, it normally looks like this:

P.S. if you followed the tutorial, and something went wrong, it will look like this:

But let’s start from the beginning!
First of all: Github gives you a great Readme for this, that’s why I link it here were needed.

Sometimes you need a List of the Database to be sorted by more than one column.

If you connect to your database with the org.springframework.data.mongodb.repository.MongoRepository you can only give org.springframework.data.domain.Sort to a search method.

This is how the Repository class looks like:

@Repository
public interface TestRepository extends MongoRepository<Test, Long> {
  List<Score> findAllByTestName(String testName, Sort sort);
}

test has some column “abc” and some column “def” and some “ghi” …. so to add the order do in th calling class something like:

The Deutsche Bahn is providing free wifi for some years now. It works for most of the people pretty well, but if you are a developer you could have some issues. I was suffering a lot with this, this is why I’m posting it, to help some of you

As you can see, the WiFi is running on the IP 172.18.xxx
