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.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

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.

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).

2. Definition
Bluetooth is a specification (IEEE 802.15.1) for the use
of low-power radio communications to link phones,
computers and other network devices over short
distances without wires.
The name Bluetooth is borrowed from Harald Bluetooth,
a king in Denmark more than 1,000 years ago.
First specification released in July 1999
5. General Specification
Bluetooth technology was designed primarily to support
simple wireless networking of personal consumer devices
and peripherals, including cell phones, and wireless headsets.
Wireless signals transmitted with Bluetooth cover short
distances, typically up to 10 meters.
Bluetooth devices generally communicate at less than 1 Mbps.
Bluetooth networks feature a dynamic topology called
a piconet or personal area networks (PAN), up to 8 devices
6. Radio Specification
• The Bluetooth system is operating in the 2.4 GHz ISM
(Industrial Scientific Medicine) band. The regulatory
range of this frequency band is 2.400 – 2.4835 GHz.
• The Bluetooth radio accomplishes spectrum spreading by
in 79 hops displaced by 1 MHz.
• Radio modulation uses GFSK.
7. Bluetooth vs. Wi-Fi
Although the Bluetooth standard utilizes the same
2.4GHz range as Wi-Fi, Bluetooth technology is not a
suitable Wi-Fi replacement.
Compared to Wi-Fi, Bluetooth networking is:
o Much slower
o A bit more limited in range
o Supports many fewer devices.
8. Bluetooth Classes
Three classes of Bluetooth devices
o Class 3 radios: have a range of up to 1 meter
o Class 2 radios: most commonly found in mobile devices,
have a range of 10 meters
o Class 1 radios: used primarily in industrial use cases, have
a range of 100 meters.
9. Link Manager Protocol (LMP)
Responsible for link set-up between devices, including
security functions :
o Authentication
o Encryption
Pairing:
o Using a shared secret (PIN), exchange random number to
form key.
13. AT Commands
AT Command Actions Return
AT Testing the connection OK
AT+BAUDx Changing the default baud rate OKbaudrate
AT+NAMEname Changing default name OKname
AT+PINpin Changing default password OKpin
