I'll provide guidelines for thinking about empirical performance evaluation of parallel programs in general and of Spark jobs in particular. It's easier to be systematic about this if you think in terms of "what's the effective network bandwidth we're getting?" instead of "How fast does this particular job run?" In addition, the figure of merit for parallel performance isn't necessarily obvious. If you want to minimize your AWS bill you should almost certainly run on a single node (but your job may take six months to finish). You may think you want answers as quickly as possible, but if you could make a job finish in 55 minutes instead 60 minutes while doubling your AWS bill, would you do it? No? Then what exactly is the metric that you should optimize?
Performance Evaluation of the KVM Hypervisor Running on Arm-Based Single-Boar...IJCNCJournal
Single-Board Computers (SBCs) were initially targeted for education and small projects with low powerprocessing needs. However, their computational power has increased dramatically in the last few years, and they are now used in more advanced developments. In this paper, a study of the feasibility of using ARM-based SBCs as hypervisors is done. The authors selected the Raspberry Pi 4 Model B and the ODROID-N2+ and assessed them as virtualization servers, when running up to four VMs simultaneously, with the Linux de facto hypervisor (KVM). The tests performed in this work include: reading and writing throughputs in different types of storage media, processing power assessment, memory performance, timed compilations of open-source software, and performance of encryption algorithms. The results of the experiments showed that the amount of memory available in these SBCs is a determinant factor about the maximum number of VMs that can be executed simultaneously. The performance of the ODROID-N2+ exceeded the Raspberry Pi 4 Model B. However, the community support received by the latter is huge compared to the one of the former, and this can be a game changer when selecting a viable platform.

Penetration Testing involves a lot of repetitive manual processes. This includes the execution of a multitude of security tools. These are traditionally executed based upon the analysis of an analyst over the duration of a vulnerability assessment. Automating a heuristic process allows an attacker additional resources for more valuable tasks through the automation of the acquisition, execution and information collection process.
A tool framework was developed by over the last few months effectively gluing over 30 unique security tools together. Each of these tools are selectively executed based of your targets available networked services dynamically.
The tools include a collection of open source, custom and commercial software with varying licensing requirements.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Comparing the Performance of Arm Based and Traditional Computers For Drug Discovery by Forrest Kamperman
1. Comparing the Performance of ARM-Based
and Traditional Computers for Drug Discovery
Forrest Kamperman, Centre College
Abstract:
This summer I did computer hardware testing at Centre
with Dr. David Toth. We tested two different types of
computers, ARM based systems and x86/x64 systems.
We used molecular docking software as a benchmark to
test their performance, and also looked at the prices of
the systems and their power consumption to find the
system that gave the best performance per dollar, and
the system that consumed the least energy. This
information would be useful for anyone looking to do
large scale calculations, especially those doing drug
discovery work. This summer also gave me a good
opportunity to view if hardware testing is the kind of work
I would like to do in the future, and into the different
aspects of writing a professional scientific paper.

Background:
There has been a recent push in computer science
towards finding more energy efficient ways of doing
large numbers of calculations, in order to lower power
consumption at large data centers. However, people
do not want to sacrifice the performance that they are
used to. One field in particular where high
performance is critical is virtual screening, where the
goal is to go through as many compounds as you can
in order to narrow it down to those most likely to work.
We decided to test out ARM based systems, which
are less powerful than the traditonal systems, but are
also much cheaper, and consume less power.
Devices:
Most of my testing was on the three ARM based mini-computers we were testing.
All three are available for under $100, and are much smaller than traditional
systems.
Cubieboard2:
This device costs around $75, contains two cores and 1 GB of RAM.
Raspberry Pi:
This is the best known device, but we found it to be the worst of the three. It costs
around $50, contains only a single core and has 512 MB of RAM.
Odroid U3:
This device cost a little over $75, and was the best system in our testing. It has
four cores, and has 2 GB of RAM.
Future Work:
After having worked at the Oregon Governor’s office last year,
my work this year was completely different. This year I worked
on research, mostly on my own, compared to working with the
public last summer. What I found is that I prefer research and
the computer science field in general to government work.
Next summer I hope to find work an internship in the private
sector, hopefully working in software development. While I do
prefer hardware testing to government work, I prefer working
with software to working with hardware.

Findings:
After all of our testing was finished, we had a clear winner.
In terms of both cost and power efficiency, the Odroid U3
was the clear winner. It required about half as much power
as the next closest device to screen 10,000 compounds,
and cost more than $10 less per 10,000 compounds
screened. Even more clear was which device was the
worst. The Raspberry Pi clearly was the least efficient
device, costing more than three times as much as the next
device to produce the same number of compounds, and
required more than double the power of the next device.
The Odroid also clearly was better than the traditional
systems, costing much less, and providing much more bang
for your buck. To build off of this, we hope to test other ARM
based systems that are coming out soon, to see if they are
just as efficient.
