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:

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

There are things that we know that we
don’t know(Known unknowns)…
There are things that we don’t know
we don’t know(Unknown unknowns)…
There are things that we don’t

5. Data mining has relevance to the fourth point in
red.
It is an art of digging out what exactly we don’t
know that we must know in our business.
The methodology is to first convert “unknown
unknowns” into “known unknowns” and then
finally to “known knowns”.
7. Data Warehousing provides the
Enterprise with a memory
Data Mining provides the
Enterprise with intelligence
Data Mining works with Data
Warehouse
8. What is Data Mining?
• Knowledge Discovery in Databases (KDD).
• Data mining digs out valuable, non-trivial
information from large multidimensional apparently
unrelated data base.
• It’s the integration of business knowledge, people,
information, algorithms, statistics and computing
technology.
• Finding useful hidden patterns and relationships in
data.
11. HUGE VOLUME- THERE IS WAY TOO MUCH DATA &
GROWING!
Bridging
the gap
Supply &
Demand
To
minimize
the
volume
12. Example of growing DATA
• Data collected much faster than it can be
processed or managed. NASA Earth Observation
System (EOS), alone, collected 15 Peta bytes by
2007 (15,000,000,000,000,000 bytes).
• Much of which won't be used - ever!
• Much of which won't be seen - ever!
• Why not?
• There's so much volume, usefulness of some of
it will never be discovered
13. Solution to the Problem of Growing
Data
Reduce the volume and/or raise the information
content by structuring, querying, filtering,
summarizing, aggregating, and mining the data.
14. Claude Shannon's info. theory
More volume, less information
Bridging
the gap
Supply &
Demand
To
minimize
the
volume
15. Decision Support
The next is the level where machine
supports decision making process by
helping in selecting appropriate
pre-defined rules.
Knowledge
Next is the level where the
machine discovers and learns
rules.
Information
In the next level is the
aggregate/summarized data.
Indexed Data
We have found short cuts, to
reach desired points in the
voluminous data sea, rather than
conventional scanning.
Raw Data
Raw data having maximum
volume
16. Amount of digital data recording and storage
exploded during the past decade
BUT
number of scientists, engineers, and analysts
available to analyze the data has not
grown correspondingly.
Bridging
the gap
Supply &
Demand
To
minimize
the
volume
17. • Limitations of OLTP systems
• Massive data sets
• high dimensionality
• new data types
• multiple heterogeneous data resources
The conventional systems couldn’t keep pace with the
ever changing and increasing data sets
• Data mining algorithms are built

18. How Data Mining is different?
▪ Data Warehouses (Data-driven exploration)
Data Mining (Knowledge-driven exploration)
Traditional Database (Transactions)
Knowledge Discovery (KDD)
19. Data Mining Vs. Statistics
Formal statistical inference is assumption driven
i.e. a hypothesis is formed and validated against
the data.
Data mining is discovery driven i.e. patterns and
hypothesis are automatically extracted from
data.

52. Clustering vs. Cluster Detection
• In one-way clustering, reordering of rows (or
columns) assembles clusters.
• If the clusters are NOT assembled, they are very
difficult to detect
First you cluster your data and then detect
clusters in the clustered data
54. The K-Means Clustering
k-means clustering aims to partition ‘n’ observations
into ‘k’ clusters in which each observation belongs to
the cluster with the nearest mean.
