Statistical Measures of Location: Mathematical Formulas versus Geometric Appr...BRNSS Publication Hub
This paper illustrates with an example of the comparison of the geometrical and the numerical approaches
of measures of location. A geometrical derivation of the most popular measure of location (mean) was
derived from a histogram by determining the centroid of a histogram. The numerical or mathematical
expression of the other measures of location, median and mode were derived from ogive and histogram,
respectively. Finally, the research establishes that the two approaches produce the same results.

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:

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

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.

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.

2. STATISTICS
Statistics, branch of mathematics
that deals with the collection,
organization, and analysis of
numerical decision-making.
3. HISTORY
Simple forms of statistics have
been used since the beginning of
civilization, when pictorial
representations or other symbols
were used to record numbers of
people, animals, and inanimate
objects on skins, slabs, sticks of
wood, or the walls of caves.
4. Before 3000 bc the
Babylonians used small
clay tablets to record
tabulations of agricultural
yields and of commodities
bartered or sold.
5. The Egyptians analysed the
population and material wealth of
their country before beginning to
build the pyramids in the 31st century
bc.
6. The Roman Empire was the first
government to gather extensive data
about the population, area, and
wealth of the territories that it
controlled.
7. Registration of deaths and births was
begun in England in the early 16th
century, and in 1662 the first
noteworthy statistical study of
population.
8. At present, statistics is a reliable means
of describing accurately the values of
economic, political, social, psychological,
biological, and physical data and serves
as a tool to correlate and analyse such
data. The work of the statistician is no
longer confined to gathering and
tabulating data, but is chiefly a process of
interpreting the information.
10. COLLECTION OF DATA:
Primary Data –
When Data are collected directly
it is called Primary Data.
Secondary Data.
If they are collected through
others than it is called
Secondary Data.
12. TABULATION AND
PRESENTATION OF DATA
1. They must be arranged either
ascending order or descending order.
2. They are grouped.
3. They are tabulated.
4. Construction of frequency distribution
table.(Grouped / Ungrouped)
13. INTERPRETATION OF
DATA.
(a) From graph
(b) Measures Of Central Tendency
(c) Measures Of Variability
(d) Measures Of Variability
(e) Co-relation
(f) Mathematical Models
15. GRAPHS Graphs are used to display
number information, or data,
in a visual way that is easy to
understand and interpret.
They are usually drawn with
two lines, called axes, which
meet at a right angle like this.
The line going across the
page is the horizontal axis,
and the line going up the page
is the vertical axis. The axes
are labelled to show the type
of data and the value of the
data being shown
20. PIE CHARTS
These have a circle divi
ded into parts, or
sectors, of different
sizes to show different
amounts of data. They
are called pie charts
because they look like
pies cut into slices.
21. MEASURES OF CENTRAL TENDENCY
After data have been collected and
tabulated, analysis begins with the
calculation of a single number, which will
summarize or represent all the data.
Because data often exhibit a cluster or
central point, this number is called a
measure of central tendency.
Mean
Median
Mode
22. MEASURES OF CENTRAL TENDENCY
Let x, x2, ..., xn be the numbers of some statistic. The
most frequently used measure is the simple arithmetic
average, or mean, written, which is the sum of the
numbers divided by n:
23. MEASURES OF CENTRAL TENDENCY
After data have been collected and tabulated, analysis
begins with the calculation of a single number, which
will summarize or represent all the data. Because data
often exhibit a cluster or central point, this number is
called a measure of central tendency.
Let x1, x2, ..., xn be the numbers of some statistic. The
most frequently used measure is the simple arithmetic
average, or mean, written , which is the sum of the
numbers divided by n:
The symbol Σ denotes the sum of all values. If the xs
are grouped into k intervals, with midpoints m1, m2, ...,
mk and frequencies f1, f2, ..., fk, respectively, the
simple arithmetic average is given by
with i = 1, 2, ..., k.
24. MEASURES OF CENTRAL TENDENCY
The median and the mode are two other measures of
central tendency. Let the xs be arranged in numerical
order; if n is odd, the median is the middle x; if n is
even, the median is the average of the two middle xs.
The mode is the x that occurs most frequently. If two or
more distinct xs occur with equal frequencies, but none
with greater frequency, the set of xs may be said not to
have a mode or to be bimodal, with modes at the two
most frequent xs, or trimodal, with modes at the three
most frequent
25. VARIABILITY OF THE DISTRIBUTION
The investigator is frequently concerned with the
variability of the distribution, that is, whether the
measurements are clustered tightly around the mean or
spread over the range. One measure of this variability is
the difference between two percentiles, usually the 25th
and the 75th percentiles. The pth percentile is a number
such that p per cent of the measurements are less than
or equal to it; in particular, the 25th and the 75th
percentiles are called the lower and upper quartiles,
respectively.
26. VARIABILITY OF THE DISTRIBUTION
The standard deviation is a measure of variability that is
more convenient to use than percentile differences as it
is defined via basic arithmetic terms as follows. The
simple deviation of a number in a set is defined as the
difference between that number and the mean of the
set. For example, in the series x1, x2, ..., xn, the
deviation of x1 is x1 - , and the square of the deviation
is (x1 - )2. The variance of the set is the mean of the
square deviations. Finally, the standard deviation,
denoted by σ (the lower-case Greek letter sigma), is the
square root of the variance, and is calculated as follows,
27. CORRELATION
When two social, physical, or biological phenomena
increase or decrease proportionately and
simultaneously because of identical external factors, the
phenomena are positively correlated; if one increases in
the same proportion that the other decreases, the two
phenomena are negatively correlated. Investigators
calculate the degree of correlation by applying a
coefficient of correlation to data concerning the two
phenomena. The most common correlation coefficient is
expressed as
28. CORRELATION
in which x is the deviation of one variable from its mean,
y is the deviation of the other variable from its mean,
and N is the total number of cases in the series. A
perfect positive correlation between the two variables
results in a coefficient of +1, a perfect negative
correlation in a coefficient of -1, and a total absence of
correlation in a coefficient of 0. Thus, .89 indicates high
positive correlation, -.76 high negative correlation, and .
13 low positive correlation.
29. A MATHEMATICAL MODEL
In a related but more involved example of a
mathematical model, many sets of measurements have
been found to have the same type of frequency
distribution—for example, the number of 6s cast in runs
of n tosses of a die; the weights of N beans chosen
haphazardly from a bag; the barometric pressures
recorded by different students, reading the same
barometer.
