Hinweis
titleTopic Info Meeting

If you plan on doing your Bachelor's or Master's thesis/P1/P2 with COSY,

we invite you visit the current semester's COSY seminar (u:find link):


For an actual agreement on supervision, please attend the topic discussion session for WiSe 2024/2025:

When: 11:30-13:00
Where: Währinger

Straß2

Straße 29, SR 8

Please prepare yourself for this session:

  • Read the topic descriptions and pick at least 2 topics that spark your interest

  • Write down your associations and assumptions about the topics (e.g. your interests, research questions and methods that come to mind). Ideally, take a first look at the available literature.

     → The better your preparation, the greater the likelihood that we can optimally supervise you (Lächeln)

Federated Online Social Network Monitoring - available

The Mastodon network - currently around 1.5  million monthly active accounts on +10000 servers - is regarded as the most successful alternative online social network yet:

https://joinmastodon.org

Unlike Twitter, Facebook, Instagram, TikTok - this service is NOT based on manipulative strategies like targeted advertising and algorithmic outrage maximisation - which are posing imminent threats to democracies worldwide - and for this reason, the network keeps evolving rapidly.

→ However, its decentralized nature creates exciting challenges for monitoring "network health".

Your task is to:

  1. Conduct research on the current state-of-the-art in monitoring of federated network statistics (e.g. nr. of posts per instance over time, blocking events, outages...)
  2. Apply your insights and ingenuity to help improving the situation, e.g.
    1. Aggregation of publicly available statistical data (via mastodon server APIs)
    2. Setup a public monitoring service directory, similar to these:
      1. https://instances.social/list/advanced#lang=&allowed=&prohibited=&min-users=&max-users=
      2. https://fedidb.org
    3. Propose new ideas on "how to measure network health" of a federated online social network

If you are interested in the future of online social networking systems (democratically legitimised moderation and algorithms + resistance against spam, censorship, denial-of-service...) then this topic may be something for you (Lächeln)

Markdown Spreadsheets -
available
assigned

Markdown is a simple text formatting method that translates to HTML and other formats easily. Extensions exist to add table formatting to Markdown as well. In this project, you devise a method to augment Markdown with spreadsheet functionality. That is, your Markdown version should understand simple formulas, cell references etc., much like LibreOffice Calc, Gnumeric, or Excel do, and be able to calculate formula values.

Outcomes of this project may include:

  • A syntax definition for Markdown Spreadsheets, both for formulas and formatting, and a simple, user-friendly serialization format which might include a preview of pre-computed values
  • A command-line program that takes a Markdown Spreadsheet, calculates all cell values, and outputs the result in a configurable format (e.g. as a Markdown Table)
  • An interactive, perhaps web-based editor with live updates
If you're interested, please contact Albert Rafetseder (albert.rafetseder@univie.ac.at)


Markdown for Questionnaires -
available
assigned

(For some context of Markdown, see above :-)

The plan for this topic is:

  1. Develop a syntax that extends Markdown to allow for a simple, text-based description of questionnaire elements such as checkboxes, lists to choose from, percentage sliders, and free-text fields.
  2. Devise a way to render such source files to HTML forms, potentially implemented as a web-based editor with live preview, and
  3. Connect them with existing Web survey software such as LimeSurvey.

The topic includes a survey and comparison of existing tools and literature on (online) surveying, a usable implementation, and a qualitative evaluation with prospective users of the technology.

A Configurable Études Generator - assigned
iLO Hacking - available

Server hardware includes management interfaces to remote-control the hardware and BIOS of a server even if the main operating system or hypervisor becomes inaccessible through usual means such as ssh. For this, a fully separate embedded system is built into the server. It provides its own firmware and operating system, RAM, storage, a separate physical Ethernet port, and low-level access to the running server hardware (e.g. fan and power supply status) and software (e.g. main memory of the server).

Little is known about the actual software comprising these management interfaces, although (mostly-informal) investigations have been conducted, e.g. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. Feel free to research other projects, useful search terms include iLO, IPMI, iDRAC, LOM, OOB, BMC...

In this project, you aim to expand and formalize this knowledge by trying out existing and developing new methods of analyzing and modifying firmware of management interfaces. A distant goal could be a fully free and open-source operating system, e.g. based on OpenWrt, for a management controller. We have multiple HP servers from different generations at our disposal for hardware analysis and hacking.

Études are musical pieces designed as practice materials for perfecting particular musical skills (Wikipedia). The skills to be perfected can differ (in difficulty and category) from étude to étude, and are different between instruments, players, and also dimensions of musical content (melody, harmony, rhythm). Develop a sufficiently generic, configurable generator for études that outputs études of choosable difficulty. For this, define a system that encodes the difficulty of a task to be studied, and transformations that assess the difficulty of combinations of study tasks appropriately.

Routing and upstream/downstream traffic flows in IP networks have certain protocol and time constraints for working correctly. This project investigates challenges and opportunities opened up by making the network's uplink change dynamically, e.g. attach to a different address block while traffic flows are still active. What happens to current-day applications in situations like these? What protocol adaptations are required to lessen the impact of uplink dynamics? What timescales are reasonable for reconvergence? (Etc.)
