Why encryption mode matters or why using encryption on hardware level is not always the best option. Some examples and short description of software level FDE implementations and features in various operating systems (with main focus to Linux dmcrypt/LUKS but also Truecrypt, loop-AES and Bitlocker).
Edward "Joe" Thornber & Zdeněk Kabeláč - Thin provisioning and snapshots in device-mapper Kernel

Lukas Czerner - Btrfs - Design, Implementation and the Current Status Kernel Historically Linux has always had quite decent pool of local file systems in the tree. However only one of them has been usually considered as a "General purpose local file system". Extended file system was the one. Now it is about to change as btrfs "B-tree file system" joined the crew. In this talk I would like to give a brief overview on the design and implementation of btrfs and highlight some if its strong and weak qualities. We might even try to peek into the future to see what the future of btrfs might look like, what might be its main use case, if it will leave all other file system behind, or silently die after the hype fade away. Finally, I will introduce you to the current state of development. I'll try to summarize what has been done so far and what you can use today. And of course, highlight features which are either ready or are about to be ready for users to appreciate. Some examples of btrfs usage might follow

The talk is intended for developer with zero or limited experience with continuous integration. Examples will be given in non-Java languages (Python, Ruby).

Better planning algorithms can help save the environment, reduce costs and improve service quality. All organisations have planning problems, such as employee rostering, task scheduling, vehicle routing or bin packing. Yet, they hardly optimize those problems. Why? Because those problems are “NP-complete”: computationally very difficult and humanly impossible to optimize.

It provides a cleaner definition of shareability and read-only settings, which gives the options to better support stateless systems, boot and virtualization.some lose definition, but we want to be much more specific. We will show the most minimal hierarchy and the hierarchy of a backwards compatible, typical Fedora installation, and explain the purpose of every directory

Travel

to Brno, Czech Republic

By Plane

Brno is located within two hours by car from three European capitals (Prague, Vienna, and Bratislava), but you can fly directly to Brno as well:

  • Brno (BRQ, 0.5 million passengers transported a year) - connections to London-Stansted (Ryanair), London-Luton (Wizz Air), Bergamo, Italy (Ryanair), Rome (Wizz Air), Prague (Czech Airlines/SkyTeam), Moscow-Domodedovo, St. Petersburg (CCA), Moscow-Vnukovo (Yakutia Airlines, UTair Aviation). Smart Wings provide seasonal flights to various destinations in Greece and Spain.
  • Prague (PRG, 13 mil.) - 210 km from Brno, 50 airlines serve flights to over 120 destinations. Student Agency buses go from the airport to Brno every hour (2.5 hours, CZK 250/€10). Flight pricing examples (roundtrips 2 months in advance, for the summer 2011):
    • New York (JFK) - (direct flight with Delta) € 826,
    • London (LHR) – (via Frankfurt with Lufthansa) € 150,
    • Madrid (MAD) – (via Dusseldorf with Lufthansa) € 150.
  • Vienna (VIE, 18 mil.) - 150 km from Brno, about 70 airlines serve flights to many destinations all over the world. Student Agency buses go from the airport to Brno every other hour (2.5 hours, CZK 310/€ 13). Flight pricing examples (roundtrips 2 months in advance, for the summer 2011):
    • New York (JFK) – (via Moscow with Aeroflot) € 843,
    • London (LHR) – (direct flight with Austrian Airlines) € 126,
    • Mandrid (MAD) – (direct flight with Air Berlin) € 144.
  • Bratislava (BTS, 2 mil.) - 130 km from Brno, 7 airlines serve regular flights to over 30 destinations, there is a hub of Ryanair (cheap flights to many European cities). There is no direct connection between the airport and Brno. Trains (€ 7, 1.5 hour) and buses (€ 9, 2 hours) go to Brno from the city center every hour.

By Train

Brno has good train connections to several European cities and train is the fastest and most convenient means of transportation between big cities in the region. All intercity trains arrive and depart at the main stations which is a hub of public transport in the city. Train timetables

  • Prague – trains between Prague and Brno go hourly, 2.5 hours, € 6.5-13,
  • Vienna – trains between Vienna Meidling and Brno go every other hour, 2 hours, € 9,
  • Bratislava – from Bratislava Hlavna Stanica hourly, 1.5 hour, € 7,
  • Budapest – from Budapest-Keleti pu several trains every day, 5 hours, € 19,
  • Warsaw – from Warszawa Centralna several times every day (usually one connection), 7 hours, € 29
  • Berlin – from Berlin Hauptbahnhof several trains every day, 7.5 hours, € 39.

By Bus

Brno is part of the European bus network and all connections and their prices are similar to trains. Most buses arrive to Brno-Zvonarka, only Student Agency buses arrive to Grand Hotel which is on the same street as Main Train Station. Student Agency (http://www.studentagency.eu/) and Eurolines (http://www.eurolines.com/) provide buses to many European cities. Bus timetables

By Car

Brno is well-connected to other cities by highways. You can get easily to neighboring countries by car. Travel time examples:

  • Prague – 210 km, 2 hours,
  • Bratislava – 130 km, 1.3 hour,
  • Vienna – 143 km, 1.8 hour,
  • Budapest – 326 km, 3 hours,
  • Munich – 587 km, 5.3 hours,
  • Berlin – 555 km, 5.2 hours.

Parking lots are available right in the university campus where the conference would take place.

In Brno

Check the map with important places including the main railway/bus stations, hotels and the conference venue at http://map.devconf.cz

Public Transport Tickets: If you want to use public transport, buy tickets only for 100+101 zones! If you're staying in Brno for several days, consider buying a 5-day public transport ticket which costs CZK 250. There are several places where you can buy it, but the best one for you is probably the main railway station, where you can buy it at any counter (look for the international ones because they more likely speak English).

From Main Railway Station to Venue

From Main railway station take tram #1 (towards Řečkovice). Get off the tram on 5th stop - Hrnčířská (after apx 10minutes). Take the street on the left - Hrnčířská - up and after apx 300 meters the building on your right hand is the University.

From Main Bus Station to Venue

From Main bus station (Zvonařka) take bus number 60, get off on second stop - Nové Sady (apx 2minutes). Take tram #1 towards Řečkovice. After two stops you are on the Main railway station, follow instructions above.

From City Center to Venue

From Česká street (City center) take trolley 32 (towards Královo pole) for 4 stops and get off on stop Botanická right in front of the main University building.

From City Center to Avanti Hotel

It's pretty much the same as going from the main train and bus stations to the venue. You get off the same stop of #1 tram (Hrčířská), you just walk the opposite direction (see the picture in the lodging section above).

From Avanti Hotel to Red Hat Office

  • If you're a group of more people, consider taking and sharing a taxi. It should cost CZK 200-300 and it's the easiest and quickest way to get to the office. Hotel personnel will certainly help you order the right taxi service.
  • If you want to use public transport, the quickest way is probably taking a #67 bus on Reissigova Street (towards Jundrov), get off on Skácelova Street stop and go a few hundred meters on Purkyňova Street to the office.
  • You can also use Google Maps to find the best way (GM work with public transport in Brno). Enter Avanti Hotel (Střední 61, Brno) as the starting point and Purkyňova 99, Brno as the destination, and select "Public Transport" as the means of transportation ("train" icon). GM will calculate you the best combination of public transport and walking.
