Linux Kernel Modules for NixOS

You can find what kernel modules are loaded using lsmod.

However some kernel modules are required at stage 1 boot. Basically preloaded in the initial ram disk before switching to the root filesystem. These kernel modules are mostly needed to deal with peripherals, storage devices, filesystems and network devices. You may need to be wary of these required modules:

• sd_mod - SCSI, SATA, and PATA (IDE) devices

• Open a webpage that uses the CA with Firefox
• Click the lock-icon in the addressbar -> show information -> show certificate
• the certificate viewer will open
• click details and choose the certificate of the certificate-chain, you want to import to CentOS
• click "Export..." and save it as .crt file
• Copy the .crt file to /etc/pki/ca-trust/source/anchors on your CentOS machine
• run update-ca-trust extract
• test it with wget https://example.com

On Manjaro (arch) the location for the certificates is: /usr/share/ca-certificates/trust-source/anchors (low priority) or /etc/ca-certificates/trust-source/anchors/ (high priority) and the command to update is update-ca-trust extract.

1. After installing mitmproxy run it (just type mitmproxy) in a terminal session and quit. This will create the necessaries certificates files at ~/.mitmproxy.

2. Extract the certificate to .crt format:
   openssl x509 -in ~/.mitmproxy/mitmproxy-ca.pem -inform PEM -out ca.crt

3. Trust the certificate into CA:
   sudo trust anchor ca.crt

4. Run the mitmproxy again

Discord Emoji

Note: This is written for those using Python 3 and discord.py, so if you're using something else please reference the relevant documentation for your language or library if you choose to use this as a general reference.

On Discord, there are two different emoji types:

• Unicode Emoji
• Custom Emoji

Each needs to be handled differently, as while unicode emoji are just simple unicode characters, Discord custom emoji are special objects available only in Discord, belonging to a specific Discord guild and having their own snowflake ID.
