Traveling

How to get from the airport to the city (your hotel)

Best option is using T-10 card (1-zone) which contains 10 tickets for 10.20 EUR. Each one of the 10 tickets can be used inside zone 1 (which includes airport) with renfe, tmb bus, nitbus, metro (except airport stations), tram, fgc, even combining them all for up to 1h 15 minutes, as long as you don't validate the same ticket in the same kind of transport twice (except in different tram/line buses, which is possible) on that period. If you do so, it will use another ticket, not the same one. Also the card can be used by different people at the same time, as long as you travel together, so you can share the tickets on the card with your friends, one ticket per person. You can find a map with metro/tram/train/fgc in here: https://www.mapametrobarcelona.com/mapas-metro/mapa-metro-barcelona-2018-01.png From the airport, you can go to the city using a T-10 ticket with renfe from Aeroport T2. You can reach Aeroport T2 with a free shuttle bus service from Aeroport T1 arrivals (after exiting, look for the first ramp going down in the right). Renfe runs a train service to Sants (main station) every 30 minutes from 5:38 to 23:38 daily, as part of line R2 Nord, and it takes around 20 minutes to arrive there. After using the train, you can change to the metro/bus using the same ticket and reach your hotel/flat. If you continue in the train, the next stop is Passeig de Gracia (7 minutes), which is near the din

Additional hints:

  • Using various taxi options (including uber and mytaxi) seems to cost around 30€ ~ 50€
  • I was unable to get a T-10 Ticket at the airport T1 metro station, even though we explicitly asked for it. But you can get it basically anywhere else. In that case it's recommended to buy an single ticket to the city and the buy the T-10 there (no need to buy a T50/30 ticket unless you plan to travel a LOT. T-10 should be sufficient if you attend conference only).
  • Awesome bike rental with perfect and strict service near Carrer Escudellers, Carrer Ample, Carrer d'Ataulf: https://www.greenbikesbarcelona.com/

To the r2con

Public transport

We use the Metro L1 to station "Glòries" which works fine.

Any free place to park my car in barcelona?

some big "supermarkets" have free parking:

  • Diagonal Mar
  • Heron City
  • La Illa
  • GranVia2

Safety concern

Barcelona is considered as a safe city. Like in any bigger city watch out for pickpockers in public transport and heavily crowded areas.

Food and restaurant hints

What to bring to the Trainings/Hackathon

  • Laptop, OS dependent on the trainings you are attending. If in doubt: most things will work in any popular linux distro, a Linux VM should also do it for most of the stuff.
  • You are welcome to bring some of your hacking gear, exotic hardware and whatnot fits in
  • If you got bring some of the nice stickers so you can exchange with other attendees
  • Power Strips and WiFi will be provided, no need for bringing your own networking equipment
  • Coffee and snacks are also being provided

r2wars bots using r2 only (2con 2017 mode):

For developing and debugging purpose we (in "we" as in communism) use the following script:

#!/bin/sh
if [ ! $# -eq 3 ]; then
	echo "Usage: $(basename $0) <arch> <bits> <warrior.asm>"
	echo "vifino's lazywarrior. (C) WTFPL"
	exit 1
fi

CMD="aei;aeim;s 100; waf $3|.; aer PC=100; aer SP=SP+100qq;Vpp;s 100"
radare2 -a "$1" -b "$2" -c "$CMD" malloc://1024

With this you don't even need to understand anything about radare2 at all. You can step/debug it by pressing "s".
