- If you spot somebody not being excellent to someone else, remind them to be excellent and have them apologi(s|z)e to the insulted part(y|ies), but only if the insulted wish to be apologi(s|z)ed to. Sometimes the insulted party will just want to move on and not have any further contact with someone who was unexcellent to them.
- Emergency numbers for your bank so you can lock your credit card/debit card/Bankomatkarte in case it gets lost/stolen/left behind.
### Emergency information
In case of an accident or other emergency condition carry a piece of information whom to contact or any special medical inforation that might be viable to your survival/first aid/medical staff.
Your personal medication does not belong on the public interwebs for your privacy. This is just a reminder to pack it. Please do not include your personal medications in pull requests. :-)
### Clothing
- At least ONE clean shirt for each day you stay, plus two for travelling to and from congress. (nerdy print is always welcome)
- At least ONE set of clean underwear for each day you stay, plus two for travelling to and from congress. (Doesn't necessarily need to be in matching pairs, but that if up to you.)
- At least ONE pair of clean socks/stockings/tights/overknees for each day you stay, plus two for travelling to and from congress.
- Enough pants/skirts/trousers/dresses/etc. so you can wear clean clothes every day you attend congress. (Even if somebody accidentally (or intentionally) spills a beverage all over you!)
- Sewing set (needle, thread, spare button for your trousers/skirts/shirts/blouses/etc.)
- Long sleeve shirts
- Hoodies, Pullovers
- Jacket (wind proof, at least somewhat water resistant)
- 3* or 5* Extension (230V≈ @50Hz) with Schuko Plug (and optional switch)
- Simple extension cord (230V @50Hz, Schuko Plug)
- USB Sticks
- Put an OWNER.txt file on them with information on how to contact you in case one gets lost accidentally. (Twitter, phone (for example DECT, 29C3 GSM extensions), email, name of the assembly you're well known at, owl, raven)
- For devices with private information be sure to encrypt them! (TrueCrypt, GPG, FileVault)
- make note of the filesystem used so you know if they will work on the system of the person you want to exchange data with. (FAT32 is a safe bet to work everywhere.)
- Mac: NTFS, ZFS, Ext can be read, but not written to without 3rd party software. FAT, ExFAT, HFS+(J), HFSX are fine for current OS X versions.
- Ethernet cords (Cat5e) of multiple lenths. Maybe have a spare to tether a friend.
- Torch (Have spare batteries or rechargables and a matching charger that works with 230V≈ @50Hz)
Read the [How to survive guide][1] in the Congress Wiki. There are many excellent tips in there.
### Backups
Make fresh backups of ALL the devices you bring to CCCongress.
### BIOS/EFI Password
Make sure you do have set a BIOS or EFI Password to prevent booting from a live CD to attack your system.
### Full disk encryption
Activate full disk encryption with pre-boot authentication. (Mac: Activate FileVault.)
### Backups
You did make fresh backups of all your devices, did you?
### VPN tunnel
Have at least one trusted, working and tested VPN endpoint available for tunneling out of the congress network.
- OpenVPN
- L2TP/IPSec
- SSH
- iodine (DNS tunnel for those pesky for-pay captive portal WiFi networks)
- Tor/Vidalia
Also have those tunnels configured on ALL the devices you intend to use, and have it tested. That includes your Laptops, phones, tablets, servers, fridge, etc.
