De toutes façons, on ne supprime jamais vraiment les choses ayant vécues sur internet. D'autant plus sur les réseaux sociaux où on ne maîtrise rien.

C'est aussi vrai en dehors des réseaux sociaux, je pourrai supprimer mon site, mais il existera des copies sur la Wayback machine.

C'est pas demain que ChatGPT vas remplacer les devs, contrairement à ce que certains laissent entendre ^^

Les gens vont très (trop ?) loin mais ça donne de bonnes idées !

In case the website goes down:

Next, figure out which device under /dev corresponds to your encrypted partition. Run

lsblk

and look for entries that have a type of "crypt". The device above that in the tree is the actual encrypted device. Record that name, and run

sudo cryptsetup luksHeaderBackup /dev/whatever --header-backup-file /tmp/luksheader

and copy that to a USB stick or something. If something goes wrong here you'll be able to boot a live image and run

sudo cryptsetup luksHeaderRestore /dev/whatever --header-backup-file luksheader

to restore it.

(Edit to add: Once everything is working, delete this backup! It contains the old weak key, and someone with it can potentially use that to brute force your disk encryption key using the old KDF even if you've updated the on-disk KDF.)

Next, run

sudo cryptsetup luksDump /dev/whatever

and look for the Version: line. If it's version 1, you need to update the header to LUKS2. Run

sudo cryptsetup convert /dev/whatever --type luks2

and follow the prompts. Make sure your system still boots, and if not go back and restore the backup of your header. Assuming everything is ok at this point, run

sudo cryptsetup luksDump /dev/whatever

again and look for the PBKDF: line in each keyslot (pay attention only to the keyslots, ignore any references to pbkdf2 that come after the Digests: line). If the PBKDF is either "pbkdf2" or "argon2i" you should convert to argon2id. Run the following:

sudo cryptsetup luksConvertKey /dev/whatever --pbkdf argon2id

and follow the prompts. If you have multiple passwords associated with your drive you'll have multiple keyslots, and you'll need to repeat this for each password.

J'ai l'impression de ne pas assez utiliser cette commande pourtant bien utile.

Sans commentaire.

Je me souviens jamais des paramètres (pourtant pas si compliqués):

# Server
iperf3 -s

#Client
iperf3 -c <my-ip> test

Reminders about some bash syntaxes I never remember :)

Read a file, line by line

while IFS= read -r line; do echo "$line"; done < file.txt

Curl with headers (in request and response)/

curl -i -X POST "http://example.com" -H "header: value" -H "another-header: value"

Cat some files in a folder (adding carriage return) (in a watch)

Here, every files matching folder-*/subfolder/file-*.txt

watch -n 1 'for file in folder-*/subfolder/file-*.txt; do cat $file; echo; done'

Pas bête le grep sur du binaire :)
J'espère ne jamais avoir besoin de faire pareil, mais on sait jamais !
Sinon, les snapshots de systèmes de fichiers comme ZFS ou BRTFS sont plus pratiques, mais on ne choisit pas toujours ce qu'on a.

NDIR vs PAS

Je me souviens jamais des options:

> ssh-keygen -lf /etc/ssh/ssh_host_rsa_key.pub
3072 SHA256:JlEdkzIPBxqBZ95UZ/fBAwtWhJlj8NQtXseDRd+5V+o root@ca.redwatch.io (RSA)

The trick is to disconnect the phone's bluetooth and close the apple watch spotify app. Then click the "download on apple watch" on the spotify iphone app. Then start the apple watch spotify app while the watch is connected to Wi-Fi but bluetooth not connected to the phone. The playlist download should start.

To close an app: Push and hold the side button and wait for the shutdown screen to appear. Push and hold down the digital crown until the app closes.

Résumé (valable pour toute application webdav):

• Partager un dossier (URL du type: https://your-nextcloud.com/s/xF4CDBt5mRCid83) avec un mdp (ex: UxMb6WFMqkoQ)
• Appli webdav:
  • url: https://your-nextcloud.com/public.php/webdav/
  • username: xF4CDBt5mRCid83 (celui du dossier)
  • mdp: UxMb6WFMqkoQ (celui du dossier)

Cela empêche le client webdav d'avoir accès à tout le nextcloud !

Tout à fait d'accord.
De plus, un thread est absolument illisible à lire sur Twitter, un post sur un blog est facile à lire.

Sous le coude pour dessiner des circuits.

Technique pour accélérer la lecture.
Je ne sais pas vraiment quoi en penser, je le mets ici plus pour garder une trace.

Logiciel reconnaissance vocale hors ligne.

scroll to the ‘about’ section and tap on the Version number 5 times (This will enable debug mode)
scroll back to the top and sign out of the Mozilla account (if needed), then navigate to Advanced settings and set the server urls:

FxA url: https://accounts.firefox.com
Token server: https://server_url

Go back to main settings and connect account, scan QR code, and have totp code ready to enter quickly (too slow and the ios app will terminate connection)

C'est juste dingue :o

What could go wrong ?
