Stamattina mi hanno mostrato il trailer del film su Tetris, che mi è sembrato altamente insipido.
|
||||
|
||||
Il fatto è che la storia di Tetris è incredibile anche senza essere romanzata.
|
||||
|
||||
Consiglio questo documentario della BBC, con immagini e filmati dell'epoca:
|
||||
https://youtu.be/NhwNTo_Yr3k
|
||||
|
||||
Fidatevi, è una storia incredibile e irripetibile.

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
|
||||
echo \
|
||||
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
|
||||

|
||||
```
|
||||
- #### Docker engine
|
||||
- ```bash
|
||||
sudo apt-get update
|
||||
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
|
||||
```
|
||||
- #### Verifica dell'installazione
|
||||
- ```bash
|
||||
sudo docker run hello-world
|
||||
```
|
||||
- #### Eseguire docker come non-root
|
||||
- ```bash
|
||||
sudo groupadd docker
|
||||
sudo usermod -aG docker $USER
|
||||
docker run hello-world
|
||||
```
|
||||
- ### Preparare ambiente *playground*
|
||||
- Clonare il repository con le immagini Docker
|
||||
- ```bash
|
||||
git clone https://git.andreafazzi.eu/andrea/acp.git
|
||||
```
|
||||
- Costruire e lanciare il container
|
||||
- ```bash
|
||||
docker compose up --build
|
||||
```
|
||||
- Eseguire accesso ssh al container (su un altro *pane* o *window* di `tmux`)
|
||||
- ```bash
|
||||
ssh -p 2222 test@localhost # password "test"
|
||||
```
|
||||
- Svolgere l'esercizio
|
||||
- Seguire il seguente URL e leggere le istruzioni riportate sul modulo
|
||||
- https://sondaggi.andreafazzi.eu/767197
|
||||
- Rimuovi il file `autosave.tmp` dalla cartella `~/playground/service1`, e produci un checksum della lista dei file contenuti nella cartella dopo la rimozione.
|
||||
- Comunicare attraverso modulo il risultato di
|
||||
- ```bash
|
||||
ls | sha1sum
|
||||
```
|
||||
- Esercizi proposti durante la lezione
|
||||
- #### Esercizio 1
|
||||
- Installa il comando `nano`
|
||||
- Entra nella `playground`
|
||||
- Crea una cartella di nome `docs` all'interno della cartella `service2`
|
||||
- Crea un file `foo.md` e inserisci il seguente testo
|
||||
- ```markdown
|
||||
# Intestazione 1
|
||||
Paragrafo.
|
||||
```
|
||||
- La risposta da inviare si ottiene facendo
|
||||
- ```bash
|
||||
cat foo.md | sha1sum
|
||||
```
|
||||
- #### Esercizio 2
|
||||
- Muovi i file `bar` e `biz` dentro `playground/service3/etc`
