Notes
L'investissement dans une pensée étant inversement proportionnel à la probabilité d'être interrompu pendant qu'on l'exprime, le repas d'aujourd'hui a été, certes, agréable, mais n'est pas le medium optimal pour donner aux questions soulevées la réflexion qu'elles méritent.
- Quelques points:
- Recrutement:
- Attractivité.
- Communication sur les activités.
- Trouver un moyen de surmonter l'asymétrie (salaire/stabilité).
- Inutile de réinventer la roue (littérature ZTO, HTAHT).
- Formation:
- Contribution dès la première semaine.
- Tutorat rotatif.
- Processus de production:
- Minimization de la gestion ad-hoc.
- Étoile Polaire:
- À n'importe quel moment on doit pouvoir répondre à la question quel est l'objectif stratégique de ce que tu fais?
- Produit phare:
- Un produit qui devrait être une manne pour la boîte.
- Capture de valeur:
- Acteur incontournable:
- Mind share.

- The Problem:
- Code updates on silver-watch master take too much time to make it to PI.
- Whenever code changes in master, it must change in device:
- Local device, two options:
- SSH into it if on same network:
- Go to repo and pull master and reboot/restart code
- Pull out SD card:
- Put it in laptop, go to repo and pull master and restart
- Remote device, two options:
- Cooperative user:
- Pull out SD card:
- Go to repo and pull master
- Make an image with dd
- Compress image
- Put image on Dropbox
- Generate Dropbox link and send it to user
- User downloads image and writes it to their SD card
- Reverse SSH tunnel to connect to RaspberryPI's behind NAT:
# On RaspberryPI: pi@raspberrypi:$ ssh -R 6666:localhost:22 pi@domain.io # On Jug's machine: jugurtha@nice:$ ssh jugurtha@domain.io # Once ssh'd, on the Server: jugurtha@domain.io:$ ssh -l jugurtha -p 6666 localhost
- I can get a shell on the remote device and do whatever needs to be done.
- Devices will have keys provisioned to them automatically.
- We can get a push based deployment this way.
- Deploy Tokens (GitLab):
- You can clone a repo without a user and password with tokens.
- https://docs.gitlab.com/ee/user/project/deploy_tokens/
- Read only or write
- Whenever the remote device boots, it pulls master (or a cron job like daily)
- This is a pull based deployment.

- Looking at "full screen application" for raspberry pi a few days ago
- Checking iPython documentation.
- Find https://python-prompt-toolkit.readthedocs.io/en/stable
- It talks about full screen applications.
- Google that. Find "kiosk application", exactly what I was looking for
- Like medianav on Renault.
