ABSTRACT
With the proliferation of technology, the field of e-learning has garnered significant attention in recent times. This is because it has allowed users from around the world to learn and access new information. This has added to the growing amount of collected data that is already being generated through different devices and sensors employed around the world. This has led to the need to analyze collected data and extract useful information from it. Machine learning (ML) and data analytics (DA) are proposed techniques that can help extract information and find valuable patterns within the collected data. In this paper, the field of e-learning is investigated in terms of definitions and characteristics. Moreover, the various challenges facing the different participants within this process are discussed. In addition, some of the works proposed in the literature to tackle these challenges are presented. Then, a brief survey about some of the most popular ML and DA techniques is given. Finally, some of the research opportunities available that employ such techniques are proposed to give insights into the areas that merit further exploration and investigation.

Barriers To E-Learning Job Training Presentation (no sound)Lisa Ronald
Learning at work as an employee is inherently different from being a student in an academic setting and, as such, is beset with different challenges. As trends in the adoption of e-learning for the delivery of job training increase, new challenges related to distance learning with technology have also emerged. Recognition that continued learning in the workplace, now via technological methods, is required for maintaining proficiency and achieving career goals means that understanding the challenges unique to learning at work is paramount.
This qualitative study explored barriers to successful online job learning. Interviews with thirty federal government employees from the Forest Service and National Park Service enrolled in an online wilderness planning course revealed that attrition frameworks typically used to describe barriers to persistence in academia and distance education only partially describe hindering factors relevant to workplace learning. Although these hindering factors can generally be categorized as workplace; personality trait, and preference; course design/structure; or technology barriers, such categorization oversimplifies the true nature of employees’ struggles to learn on the job.
This study's findings reveal three overarching systemic problems: 1) illusion of convenience, 2) absence of deeper learning, and 3) lack of an organizational culture of learning. These systemic problems demonstrate that complex interactions between various barriers create a cyclic system often preventing attainment of student-controlled, student-centered learning, two benefits of self-paced study. Other barrier interactions can foster employment of superficial, rather than deep, learning strategies possibly leaving employees ill-prepared to negotiate the situations for which they are supposedly being trained. Cultural elements of the structure and organization of work suggest that workplace learning is devalued, under-recognized and often unsupported, making the challenges to adaptation in an increasingly technological era even more significant.
These are the slides of a presentation given on 1st September 2011 to colleagues at the Chinese University of Hong Kong. In the presentation, I described and reflected on my experience of using podcasts in teaching Hong Kong Land Law.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

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:
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.
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.

background, learning styles, study habits,
attitudes toward the use of podcasting in
teaching and learning
Given to students in face-to-face and online
classes of all levels
965 students responded to the online
questionnaire
17. Pilot Study Results (Cont.)
48% of the students completing the
survey were between 20-25 years of
age
72% of the students were females
A great majority of students (84%) had
a high speed or LAN connection to the
Internet
Over 37% of the students took a fully
online course or hybrid/blended class
18. Pilot Study Results (Cont.)
Over 40% of the students lived more
than 16 miles away from campus
About 43% of the students’ typical
commute time was over 20 minutes
Over 20% of them spent over 60
minutes on the road to campus
19. Pilot Study Results (Cont.)
62% of the students own either iPod or
MP3 player
More than 40% of them spend 10-20
hrs/week using their iPod or MP3 player
Almost 45% of them use their iPod or
MP3 player while walking or jogging
65% of the students have knowledge
about podcasting, but 41% have ever
listened to a podcast
20. Pilot Study Results (Cont.)
Nearly 90% of the students are
interested in accessing instructional
materials with their iPod or MP3
Player
Almost 55% of the students indicated
that a class that is being podcast
makes them more likely to take it
21. Pilot Study Results (Cont.)
74% of the students have been using a
computer for 8 or more years
36% of them do not know whether they
prefer using an iPod or MP3 player to
using a computer nor do these

Students preferred video podcasts
(58%) rather and podcasts with audio
and still frames (23%) and (15%) with
only audio
23. Pilot Study Results (Cont.)
Students strongly favored classes using
podcasting for the ability to review materials
repeatedly and whenever they wanted
Some students preferred taking classes that
offer podcasting, liked combination classes
that used face-to-face classroom experience
and podcasting, and were much more likely
to take a class offering podcasting, and
indicated they would be more likely to use
an iPod or MP3 if it were available
24. Conclusions from the Pilot Study
Students at USM are interested and would like to
have podcasting implemented into their classes
The data should be used to design and develop
instructional podcasts that will help instructors and
