Vehicle Surround View

Apakah kamera seperti [10], dengan konektor rca to usb [11] dapat "dibaca" langsung di android atau minimal di linux dulu ? kalau bisa, bagaimana cara membaca ke empatnya sekaligus ? jika sudah bisa, coba pelajari dokumentasi terkait surround view [4]. 

Kalau ini bisa dilakukan, maka untuk membuat surround view di kendaraan kita, kita cukup  beli 4 buah kamera, konverter dan memanfaatkan device android yg kita punya.

Dragonfly : source-available, multi-threaded Redis® replacement built for modern cloud workloads

 

Migrasi Single Node Redis ke Dragonflydb

File backup redis : dump.rdb

Pastikan dragonlydb service sudah mati.

sudo systemctl stop dragonfly.service

load dump.rdb ke memory dengan dragonfly : 

sudo dragonfly --logtostderr --dbfilename dump

dengan redis-client, save ke format dfs :

redis-cli
save df

Hapus data lama, dan pindahkan data baru :

 sudo rm /var/lib/dragonfly/
 

dari path tadi menjalankan perintah  load dump.rdb :

sudo mv *.dfs /var/lib/dragonfly/

Jalankan dragonfly :

sudo systemctl start dragonfly.service

How to make dragonfly service start automatically in debian 12

To make the dragonfly.service start automatically in Debian 12, you can use the following steps:

1. Open a terminal window.
2. Run the following command to edit the dragonfly.service file:

sudo nano /etc/systemd/system/dragonfly.service

3. In the dragonfly.service file, add the following lines to the [Unit] section:

Description=Dragonfly Service
After=network.target

4. In the [Service] section, add the following lines:

ExecStart=/usr/bin/dragonfly
Restart=always

5. Save the dragonfly.service file and exit the nano editor.
6. Run the following command to reload the systemd daemon:

sudo systemctl daemon-reload

7. Run the following command to enable the dragonfly.service service to start automatically at boot:

sudo systemctl enable dragonfly.service

8. Run the following command to start the dragonfly.service service:

sudo systemctl start dragonfly.service

The dragonfly.service service should now start automatically at boot and whenever your system restarts.

Tuning

Di [1] ada instruksi untuk mengubah settingan mysql menjadi : 

[mysqld]
innodb_file_per_table = 1

character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
skip-character-set-client-handshake

Konfigurasi ini, terutama : innodb_file_per_table,  jika diterapkan di TAO, apakah dapat meningkatkan performa nya ?

Single Sign On 

Matriks fitur module-modul SAML SSO yang ada

No	Moodle Plugins	Auto-create user	Auto-enroll	Single Sign Off	Limit concurrent login	Dual Login
1	Authentication ::: auth_saml2sso	v		v	v	v
2	Authentication ::: auth_saml2	v		v		v
3

Authentication ::: auth_saml2 

Dual login auth_saml2 | duallogin : Yes/No (Default Yes)

If on, then users will see both manual and a SAML login button. If off they will always be taken directly to the IdP login page.

If passive, then the users that are already authenticated into the IDP will be automatically logged in, otherwise they will be sent to Moodle login page.

If off, then admins can still see the manual login page via /login/index.php?saml=off

If on, then external pages can deep link into moodle using saml eg /course/view.php?id=45&saml=on

If set to test IdP connection, the network will be checked for connectivity, and if functional, SAML login will be initiated.
