The document summarizes Riina Vuorikari's presentation on using social information retrieval techniques to enhance the discovery and reuse of learning resources. The presentation outlines the context of Vuorikari's dissertation work, which examines how teachers tag and use social bookmarking tools in a multilingual environment. It then discusses the main research questions, experimental design, and some early analysis of user behavior based on data from pilot projects with teachers across Europe. The analysis shows that teachers tag resources in multiple languages and the tags have potential to connect teachers across borders if certain challenges are addressed.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

First evaluations so far:
●
Multi-lingual use of tags
–
Levels of user engagement
–
4. Context
European education, especially that of K-12
●
education, is inherently multilingual and
multicultural.
European teachers have access to multiple
●
repositories of digital learning resources by
Educational Authorities,
–
publishers,
–
other teachers,..
–
6. Context
Resources
●
In many different languages
–
For different national and regional curriculum
–
Contain metadata (e.g.title, keywords, language)
–
Of varying quality
–
Repositories have formed federations to
●
make resources available
Federated search based on metadata
–
Harvesting of metada
–
7. Challenge for users
End-users (e.g. teachers) have difficulties to
●
discover and find resources from educational
repositories
Metadata does not always match search terms
–
Locating content across linguistic and
●
national borders within Europe has proven
hard
Despite the use of a multilingual Thesaurus and
–
controlled vocabularies
8. Challenges for repositories
Users become more demanding and expect
●
services that are seen elsewhere (own
collections, pedagogical hints, ..)

Can Social Information Retrieval
Enhance
the Discovery and Reuse
of
Learning Resources?
10. Social Information Retrieval
(SIR)
Refers to a family of techniques that assist
●
users in obtaining information to meet their
information needs by harnessing the
knowledge or experience of other users.
Examples of SIR techniques include:
●
sharing of queries,
–
collaborative filtering,
–
social network analysis,
–
social bookmarking,
–
subjective relevance judgements such as
–
tags, annotations, ratings and evaluations,
etc.
11. What is SIR for education?
Is education as a field of implementation that
●
different from other fields (e.g. music, movies)?
What are the domain specific requirements, where
●
does the data come from and what are its
semantics?
What are objects of recommendation?
●

14. Main research questions 1
Teachers, tagging, languages:
How do teachers tag and use social
●
bookmarking in a multi-lingual environment?
Are those bookmarks and tags useful for
●
discovery of resources?
How about tags in multiple languages?
●
15. Main research questions 2
SIR aspect:
Can bookmarks and tags be used to connect
●
like-minded teachers cross country and
linguistic borders?
...and thus used for social information
●
retrieval?
What are the levels of user engagement
●
with the system?
16. Main research questions 3
Information Seeking aspect:
What are the main information seeking tasks
●
that teachers have?
What are the main SIR retrieval methods that
●
they use for them?
Can we match a task to a SIR method?

triangulation of collected data.
log files from the portals to see the grand lines,
–
patterns, etc
complimented by some questionnaires to
–
understand groups or communities
possible interviews, thinking alouds, observation,
–
etc. on some few users to understand individual
behaviour.

32. Visualisation tool for cross-
country use of bookmarks
Prototype tool to visualise
●
Bookmarks (title, classification keyword, country)
–
Tags (language)
–
Users (name, country, language)

34. Distribution of bookmarks
Average: 6 bookmarks
●
Wide distribution:
●
10% “Super users”
–
more than 20
15% 20-6 bookmarks
–
45% 6-2 bookmarks
–
About 30% only
–
experimented (1)
35. Language analysis
Out of 417 tags many were with multiple
●
terms, when separated we found 585 terms
1/3 in Hungarian
●
26% in English, even though none of the
●
users were native English speakers
1/3 in German and Polish
●
36. Language analysis
The language was right in about 70% of
●
cases (from the interface), and found out
that...
...users tag in many different languages:
●
at the same time (e.g. Baum, arbre, tree)
–
at different times (once in Pl, other times in En)
–
use the interface in different languages (seems
–
like not only to test)
37. Btw, what do others do?
del.icio.us, Yahoo.fr, MyWeb.Yahoo.uk,
●
blogmarks.net, MisterWong.de...
Two different ways to deal with multiple
●
languages can be observed;
ones taken care of by users (i.e. crowd-
–
sourcing”)
others where the system supports multiple
–
languages to certain extent
38. Does the language matter?
Need for better ways to identify the language
●
Give rules (if the user first preferred languages is.., then..)
–
Automate the recognition of languages
–
Out-source it to users
–
39. Semantic analysis
Factual tags 63%
●
(Golder: item topics, kinds of
item, category refinements)
Subjective tags 29%
●
( Golder: item qualities)
Personal tags 3%
●
(Golder: item ownership, self-
reference, tasks organisation)
5% other
●
Sen et al. (2006).
●
40. Why tag categories?
In Sen et al. (2006)
●
it was found that
tags of different
categories can be
useful for different
tasks
In our case it is too
●
early to say
anything, but ...we'll
have an eye on it!
41. “Travel well” tags
About 13% of tags contain a general term, a
●
name, place
e.g. EU, Euroopa, Europa, europe,
●
geograafia, Pythagoras, etc.
42. What's the point of travel well
tags?
If those tags need no translation or language
●
filtering to be understood, and ..
..if they can be identified
●
We can be sure to show at least some tags
●
to users
whose language preferences we don't know, and
–
in which language there are no tags or keywords
–
available.
44. Usefulness of tags..
Overall, the thesaurus terms performed
●
better than the tags,
However, it can be argued that tags, after all
●
being produced with no outlay, showed an
overall encouraging and potential gain in
overall usefulness!
45. So what is needed?
HIDE ALL BUT THE RIGHT STUFF!
●
In the tagging interface (guided tagging)
●
Show tags in all languages?
–
Show only travel well tags?
–
Show only tags in users' preferred languages
–
While viewing the tags
●
In a tag cloud
–
For social navigation (resource-user-tag)
–
Q: does the system translate tags or only when a
–
user-given translation exist?
46. Future studies
Similar language and semantic analysis are
●
planned for a more thorough data in 2008
Moreover, our goals are to find out:
●
How do users use the tags (e.g. language and
–
tag convergence) ?
How are tags and the relation resource-tag-user
–
used for discovery?
Identify teachers information seeking tasks and a
–
best fit for a retrieval system.
47. User engagement
Inspired by Yahoo!'s START
●
rating shows the first level of engagement;
–
then tags it;
–
user views a page;
–
forwards it to friends,
–
and finally writing a review
–
How can this be used for recommending
●
purpose?
48. User engagement
In our case these
●
look very different:
views the page
–
views metadata
–
bookmarks and tags
–
rates
–
actual use?
–
49. That's it for now!
