[HIForum] Computer-Museum im Advent

Liebe HIForum-Mitglieder,

es gibt eine tolle Chance, in Ruhe das Museum zu besuchen, hier ist die Einladung an den Fachbereich, die ich gerne an unsere Vereinsmitglieder weitergeben möchte:

ich habe eine Lücke im Kolloquiumsplan entdeckt und möchte sie mit einem Angebot schließen:

Advent im Computer-Museum
Montag, 3. Dezember
14:00 - 18:30 Uhr Open Museum mit Heißgetränken (Glühwein, …) in Haus C, Keller C-015
16:00 - 17:30 Uhr Führung (max. 12 Personen, Anmeldung per E-Mail an oberquelle@informatik.uni-hamburg.de), 
Treffpunkt Eingang Haus B (Konrad-Zuse-Hörsaal)

Dies ist für 2018 die letzte allgemeine Chance, das hoch interessante Computer-Museum mit seinen Hunderten von Exponaten live kennen zu lernen.
Interessenten für eine Führung zu einer anderen Zeit sollten eine Gruppe sammeln und mich kontaktieren.

Mit besten Grüßen
Horst Oberquelle

Abstract

One of the Internet's greatest strengths is the degree to which it facilitates access to any of its resources from users anywhere in the world. The Internet has already become a crucial part of our life. People around the world use the internet to communicate, connect, and do business. Yet various commercial, technical, and national interests constrain universal access to information on the internet.

 

I will discuss three reasons for the closed web that are not caused by government censorship: blocking visitors from the EU to avoid GDPR compliance, blocking based upon the visitor's country, and blocking due to security concerns. These decisions can have an adverse effect on the people of the blocked regions, especially for the developing regions. With many key services, such as education, commerce, and news, offered by a small number of web-based Western companies who might not view the developing world as worth the risk, these indiscriminate blanket blocking could slow the growth of blocked developing regions.

 

As we are building the future web, we need to discuss the implication of such blocking practices and build technologies that ensure an open web for users around the world.

Abstract

From cloud servers to IoT devices, modern CPUs provide a complex microarchitecture to ensure high performance while easing parallelization. Unrelated services often run in parallel on the same platform and share resources. At the logic level, sandboxing ensures isolation between services. However, isolation is not perfect, and side channels caused by the CPU's shared microarchitecture can result in unintended information leakage across processes and virtual machines. For instance, cache attacks that exploit access time variations when retrieving data from the cache or the memory are a powerful tool to extract information from a co-located process. - This talk provides an overview of how microarchitectural features of modern CPUs such as shared caches and speculative execution can be abused to circumvent isolation techniques. It will be shown how the resulting attacks can be applied to extract sensitive information from privileged processes and even across processor boundaries. Modern attack techniques such as cache attacks as well as the infamous Spectre and Meltdown attacks will be presented and discussed.

Abstract:

With the increase of interconnectivity and ubiquitous data access, new services have emerged. Distributed Ledger Technologies and their underlying principles can be used to reach agreement or consensus upon a distributed state in a highly distributed environment. They have many different aspects and can therefore be viewed from various angles, including the financial and economic, legal, political, and sociological perspective, as well as considering technical and socio-technical points of view. In the presentation I will show three aspects that are important in our research: (1) theoretical foundations, (2) understanding real world phenomena, and (3) impact. For instance, proof-of-work (PoW) as used in Bitcoin is not only relevant to achieving consensus but also serves as a source of randomness. Without it leader selection becomes an issue. Finally, understanding economic incentives and malicious behavior to undermine consensus in public blockchains is important to create a stable cryptocurrency environment upon which new services can be built.

Dear Colleagues,


This Wednesday, we will kick off our public lecture series „Taming the Machines" - Discussing the Ethics of Information Technologies

 

Regulated Data - Regulated Activism? Digital Activism in the GDPR Era

Professor Payal Arora, Erasmus University Rotterdam/Catalyst Lab

 

When: 14th November 2018, 18:00-20:00

Where: lecture hall B, main building at Edmund-Siemers-Allee 1, University of Hamburg

 

About the lecture

In a favela ruled by the drug lords in Rio de Janeiro, an activist uses Facebook Live to capture the dealings in his neighborhood, putting himself and some of his community members at risk. In Jeddah, Saudi Arabia, a few teenage girls instagram the fashions of the week, unveiled, an act that can be persecuted by the morality police. In Jammu and Kashmir, some activists through the hashtag #justiceforkathua draw attention to the case of an eight-year old nomadic girl who was gang raped, defying the privacy law on revealing identities of minors. These are just some of the many cases that shed light on the gray area between privacy and protest. Contrary to seeking to be protected through anonymity as the bulk of the current research alludes to, some of those at the margins may choose to put themselves at high risk by being visible and heard. The GDPR, rooted in the Western ideology of individual choice and rights, may have created a privacy universalism, begging the question of whether privacy is a privilege and a luxury. This talk draws from a decade of fieldwork and activism among vulnerable communities beyond the West to grapple with the question of whether privacy and activism are after all compatible.

 

About the speaker

Payal Arora is the Founder of Catalyst Lab, a digital activism organization and an Associate Professor at Erasmus University Rotterdam. She has consulted for the private and the public sector including for UNESCO, World Bank, hp, The Ministry of Jordan, Kellogg and Siemens. She has published about fifty papers and given more than a 125 presentations in 70 cities and 30 countries, including a TEDx talk on the future of the internet. Arora sits on multiple boards including the Facebook Election Advisory Commission, Columbia University's Connect to Learn, and The World Women Global Council in New York. She is the author of several books on the internet and the Global South including the upcoming 'The Next Billion Users: Digital Life beyond the West' with Harvard University Press.
