Lessons learned and future activities / struggle against software patents

^{The software patents directive was rejected by a big majority in theEuropean Parliament in the beginning of July. What have we learnedfrom lobbying on European and national level? And how can we applythat information to other issues?There is already a new directive proposed by the commission about theenforcement of "Intellectual Property" rights. There is also pressurefrom big media companies to make copyright last even longer than itdoes today. How are we going to make sure that the politicians willunderstand these issues and make the right decisions in the future?}

^{Often compared to Leonardo da Vinci, R. Buckminster Fuller (‘Bucky’) was extremely productive in many fields during his 50-year “experiment to discover what the little, penniless, unknown individual might be able to do effectively on behalf of all humanity.� Among his many revolutionary designs are mass-produced housing, a new geometry system, the first aerodynamic car, a new type of map, and the geodesic dome. Fuller was one of the earliest proponents of renewable energy sources, at a time when the concept was largely unknown. It was his firm belief that for the first time in history, we have the option to produce a high standard of living for all people on an ecologically sustainable basis.The story of Fuller’s life, his inventions and his ideals is fascinating, yet unknown to most people currently aboard ‘Spaceship Earth’. In this age of globalization, his refreshing worldview is more appropriate than ever and can serve as an inspiration to all who are interested in the application of technology for the benefit of all humanity.}

^{This is about propaganda and manipulation in our (information)society. It is about the creation of public and individual opinion, of our view of the world and of the neccessary illusions that make our system function. I raise and answer the following questions:are we manipulated?who does that?why do they do that?how does it work?I talk about politics, media, corporations, pr industry and about psychological mechanisms of individuals and crowds. I do so because I believe that only (!) understanding these matters can help us escape manipulation and shape a democratic world.}

^{Copyright law and digital rights management are gearing up for even bigger battles than the ones we've seen at EFF in the last five years. The US Supreme Court will almost certainly decide the Grokster case this summer. Intel, Microsoft, AMD, and a scurvy gang of hangers-on like anti-spammers, disk drive and monitor makers are trying to lock-down every new PC so the owner can't control what software runs on it, it can't get on the Internet or run popular protocols using unapproved software, etc. Ultimately this is all about propping up monopolies, and they might get away with it. The decisions made by informed or ignorant consumers (and the journalists who inform them) will determine whether today's freedom survives.}

^{For four decades, the field of data compression has attracted some ofthe world's best statistical minds. Using basic principles of statisticalreasoning, we have managed to create a wide variety of "general" purposedata compressors such a bzip, gzip, and PPM that can shorten files. In mytalk I will explain how to use these same programs to do all sorts ofinteresting pattern recognition. I will present a way to convert anycompression program into a statistical inference engine suitable for awide variety of tasks, including:a) evolutionary tree reconstruction from genomic sequence datab) detecting viruses, worms or other bad packetsc) determining language relationships from text samplesIn more recent research, we have recast the Google search engine as asort of pseudo-compressor, and used this to use Google to do veryadvanced semantic classifications, so that a computer can by itselfdetermine the difference between colors and numbers, or arrange paintingsby painters, without ever being told explicitly what to do. This possibilityto do objective or subjective reasoning holds great promise for futuremachine learning applications.}

Against Free Speech and Democracy

^{In the WTH opening keynote speech, Rop and Emmanuel usedthe concepts "freedom of speech" and "democracy" severaltimes, drawing some of the loudest applause. These conceptsseemed to be tied to hacker identity, along with themore traditional themes (valuing knowledge and sharing,desire for exploration, obtaining new skills,reusing techniques and materials in the least expected way,and so forth).This session will question the implication that the hackerethic must include freedom of speech and democracy amongits tenets. It will start with the speculation that thisapproach threatens to enslave the spirit of hackers to thelanguage of the masters.Are hackers at large really such a state and Kapital-lovingbunch? Come to this session to hear some assumptions questioned,and to engage in public debate over shared values.}

^{A soft partitioning concept based on 'Security Contexts' which allows to create many independent Virtual Private Servers (VPS), similar to normal Linux Servers, which can be run simultaneously on one box at full speed, sharing the hardware resources. All services, such as ssh, mail, Web and databases, can be started on such a VPS, without (or in special cases with only minimal) modification, just like on any real server. Each virtual server has its own user account database and root password and doesn't interfere with other virtual servers, except for the fact that they share the same hardware resources.}

Hacking the Memory Hierarchy

^{Data-intensive query processing tasks like data mining, scientific data analysis, and decision support can leave a database system severely I/O bound, even when common RAID configurations are used. Traditionally, this problem has been tackled by adding more and more disks, connected through expensive interconnect networks. This brute-force approach results in systems of which the price is dominated by the cost of their disk subsystems and a lot of disk space is wasted as disks are only added to gain bandwidth.A more subtle and cost-effective solution can be found in data compression, which has the potential to alleviate the I/O bottleneck. However, traditional algorithms like Huffman coding, Arithmetic coding and Lempel-Ziv style dictionary methods are not suited for this goal due to high processing overheads.In order to be of practical value, even on common RAID configurations,decompression algorithms should be capable of producing roughly one byteper CPU cycle on modern hardware, or around three gigabytes per second.To achieve this, a case is made for novel,light-weight compression algorithms, which exploit both the structure of theunderlying database and the characteristics of modern CPUs.In general, performance is prefered over compression ratio, and algorithmsshould strive to extractmaximum instructions-per-clock-cycle (IPC) from modern CPUs.Furthermore, to rule out main memory bottlenecks, candidate algorithms shouldallow for incremental, into-cache decompression.This presentation introduces three novel compression schemes (PFOR,PFOR-DELTA, and PDICT) that are designed towards these goals.Experimental results show that these methodscan significantly alleviate I/O-, and sometimes evenmain memory bottlenecks, thereby effectively increasing the performance of todays hierarchical memorybased systems.Target audience: high performance computing, large databases, hardware architecture.Skills that are a pre: modern CPU internals, hierarchical memory design, C programming}

^{Radio Frequency Identification (RFID) is a popular contactless identification technology which has been hyped as the "next generation barcode". These tiny inductively-powered computer chips have already been integrated into consumer goods, passports, public transportation tickets, and even people. Because most RFID tags lack privacy enhancing technologies or cryptography, governments, corporations, and malicious individuals can use RFID technology to track and create behavioral profiles of everyday people.Effective RFID surveillance and tracking depends upon the proper functioning of RFID systems. Just as hackers can cover their tracks against Intrusion Detection Systems, concerned individuals can fight back against RFID surveillance by introducing false positives and false negatives into RFID systems. Non-malicious “RFID abuse� is likely to appear in forms ranging from self-defense to practical jokes to activism. This presentation will discuss many of the ways to abuse RFID systems, and will then examine the resulting dilemma facing RFID system operators.}

How to build your untraceable home page

^{In this workshop/tutorial, I'll walk you through how to configure Torplus a basic web server to create a "hidden service" -- a website thatother Tor users can access without knowing its physical or networklocation. Because you don't need a public IP address, you can run yourhidden service just fine from deep behind the corporate firewall -- if youcan get to the Tor network, you can offer a hidden service. This approachworks because of Tor's rendezvous point design: both sides build a Torcircuit out, and they meet in the middle. Hidden services are more robustto censorship, because you can't find them to DoS them or shut them down.We'll also discuss some of the risks involved, performance and scalingchallenges, and potential attacks that we don't have good answers for yet.}

Can software radio help us build our own passive radar systems?

^{Passive radar systems take advantage of "illuminators of opportunity"-- other people's transmitters -- such as TV, radio and cellularbasestations. Using multiple antennas and/or multiple receivers and abunch of signal processing we believe we will be able track thevelocity and position of "interesting objects". We also believe thatby observing the variation in radar cross section over time, we shouldbe able to identify the class of the objects that we're seeing.}

^{Cellular telecommunication networks provide the position of mobile users confidential, since the communicating peers are not aware of the location of each other. This feature is based on that a mobile telecommunication infrastructure is in one hand, one organisation controls it. The different cellular networks are joined to provide roaming, as each participant are trusted in each other and all of them provide location hiding of the mobile users. In a mobile telecommunication infrastructure, the communication usually encrypted, its lines are physically separated, so it is hard to tamper with. Moreover, there are only a few nodes, which are aware of the mobile users. In addition, in GSM networks each mobile user have the same constant voice bandwidth, therefore it is impossible to distinguish them by their traffic flow patterns.In the IP networks, the support for mobility has gained high importance. In the recent researches, mostly the optimisation of network parameters, like bandwidth, delay etc. are emphasised. Also efforts have been made to provide basic security services as confidentiality and authentication of signalling, user and its traffic. Unfortunately, the issues raised by the location confidentiality have not investigated deeply. The Internet consists of different size and from different security level IP networks, with different trust relationships. Even if the traffic is encrypted and the source identification data (e.g. source IP address) is not known, there are methods to reveal the location of mobile users by investigating in its traffic patterns.}

Politicizing Hackers and Hackerizing Activists

^{Is hacking inherently politcal? If there were a hacker political party, whatwould be the planks in its platform? How can positive hacking help activistmovements? As social networking tools that actvists use (yahoo groups,friendster, orkut) are co-opted by the traditional media illuminati, whatbecomes of the hacker ethic of non-proprietary social communities? This talkattempts to look at some of these questions- part historical look at the gapbetween hacker tech and activist tech, part reportback on some recentspecialized conferences attempting to bridge the hacker and activist worlds.}
