Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

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.
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.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

Professor: Merlyna Lim
2. What IS Nuclear Technology
Images of our world
Weapons
Reactors
Nuclear waste
Hiroshima
Anti Nuclear Protests
Media bring nuclear technology to our attention
How to sort out the issues from the noise?
4. Scientific Views
for easy introduction:http://
www.youtube.com/watch?v=fjgdgAhOzXQ
ENERGY -- the driving force of change
ENERGY -- heart of nuclear technology;
radioactivity, nuclear fission, and nuclear fusion
(reactions) are also driven by energy
5. Energy plays an important part
And it’s used in all this work;
Energy, yest energy with power so great,
A kind that cannot shirk.
If the farmer had not this energy,
He would be at a loss,
But it’s sad to think, this energy
Belongs to a little brown horse.
A school verse by Richard Feynman
a Nobel laureate for physics
6. Nuclear ENERGY
Energy forms -- transfer and conversion (recalling
your high-school physics class!!)
Part of nuclear technology -- for the conversion of
nuclear energy into heat and electric energy; its
development is related to the development of other
technologies
The Sun is a nuclear fusion reactor -- nuclear
technology imitates the energy producing process of
the Sun
7. Nuclear Fission
A process by which a heavy nuclide splits into two
of more pieces -- became the top secret in Germany,
England, the former USSR and the United States
Transuranium: Fermi (1901-1954) in Rome, F. Joliot
(1990-1958) and I. Curie in Paris, and Otto Hahn....
8. Nuclear Fission
Uranium isotopes -- 235U
How much energy is released per fission reaction?
How can the amount be estimated or calculated?
What are the applications of fission energy in war and peace?
235U to give two nuclides --> 117Sn50, and 118Sn50, their masses being
116.902956 and 117.901609 amu respectively. The mass of 235U92 is
235.043924 amu. The difference in mass: 235.043924 - (116.902956 +
117.901609) = 0.2394 amu (931.5 MeV/1 amu) = 223 MeV.

13. Nuclear weapons: Can any rational person
make a case for their continued existence?
Nuclear reactors: if they are very dangerous,
can we afford to use them?
20. Media Stories
Do I have to worry about radiation on airplanes?
Is flying like working in a nuclear power plant?
Does that mean nuclear plants are safe or flying
is hazardous?
29. Radiation Fictions
• Fear:
– “It’s gonna blow!!!”
• Controversy:
– “We’re all gonna die!”
• Misunderstanding:
– “It’s not natural!”
• Mistrust
– “They’re all liars. We know
mutant bugs will take over the
earth and enslave us.”
30. Nuclear Technology
Too little we know on ‘what it is’
Dominant perception (mainstream political stories, media
representation) reflect only partial truth
Preconceived notions can hinder clear thinking and fruitful
discussions
Don’t we need to understand the basis of the technology to
be able to come to ‘better’ decision?
Doesn’t public deserve more information?
Doesn’t public (us) need to be better informed?
31. Radiation Facts
It’s been around forever
First was noticed ~ 1895
A lot was learned since then:
– doctors & radiation could cure cancer
– quacks & radiation could kill people
– the Military & radiation could kill a LOT of
people
32. Environmental Radiation
• Radiation & radionuclides
older than the Earth
• Natural part of our
environment
• Radiation field varies by
geology, elevation, season,
living conditions
35. Range of Doses
General public - 360 mrem/y natural
Radon: 200 mrem
Other natural: 97 mrem
Remainder ~ 15 % medical, 3% products, 1% other
Medical procedures (per procedure)
CT head and body: 110 mrem
36. %Contribution to Dose
• Contribution of various radiation sources to total
average dose equivalent to persons in the United
States (NCRP, 1987).
37. Basic Facts
• Two main types:
– electromagnetic (X-rays and gamma rays)
– particulate (electrons, protons, alpha particles..)
• Produced in the nucleus or through atomic orbital
transitions
• Capable of ionizing (removing electrons) from
atoms

Why the “uncertainty”?
Not all effects are apparent
Knowledge limitations (likely impact)
Natural variations (radiation field changes)
Measurement ability (you can only go so low)
Dose is predicted

47. Radiation Effects Data
Mainly for people or lab rats
Good data in high dose/high dose-rate region
Limited/contradictory data in low dose/low-
dose rate region
Some data suggest threshold (~10 rem)
48. What about other
Insects are tough to kill
Big trees are as sensitive as we are
So are most mammals
Fish and plants are about 10x more resistant
But…..
radionuclides are “more concentrated” lower in food
chain

Radiation in high doses can kill you
Radiation in moderate doses increases your
cancer risk
Radiation at doses near or below background
may :
do nothing ???
help you ???
51. Should we sink ourselves in ‘the fear’ of
technology? Just based on too little
knowledge... of we have seen and heard?
Nuclear..... “clean technology”, how clean is
clean enough?
“a little bit of knowledge is a dangerous
thing.....”
