This document describes the history and development of OpenPipe, an open source bagpipe MIDI controller. It started in 2000 as a resistive prototype but has now evolved to use capacitive touch sensing with an Arduino. Various sound generation methods are discussed, from PWM to audio shields to MIDI output. The goal is to create high quality open source bagpipe samples and apps to improve the playing experience. Future plans include a standalone OpenPipe ONE device and expanding the project.
Arduino first and foremost is an open-source computer hardware and software company. The Arduino Communityrefers to the project and user community that designs and utilizes microcontroller-based development boards. These development boards are known as Arduino Modules, which are open-source prototyping platforms.

Getting started with Arduino Programming can be daunting. These are slides I used in my classes which introduced programming concepts to non-engineers, non-programmers, but totally people who wanted to learn more about electronics.
Robotics and Arduino. A simple presentation about how a microcontroller works and a "Hello World" project/program. Blinking a led. Atmega328p info about architecture.
Have you heard of internet of things - where all kind of gadgets get connected so we can make better use of them ? Arduino is easy to learn platform that can help us to do exactly this - connect things, invent gadgets and experiment with them. This will give you joy because it is easily done and in the end you can touch your creation not like the software.
The basics of understanding electronics and physical interaction with Arduino presented and taught by Jörn Sandner, Prof. Franziska Hübler and Jeremy Abbett for the University of Applied Arts - Hamburg and Miami Ad School Europe.
18/03/2010 - FTS seminar series @ Cardiff Univesity, Computer Science. Pete Woznowski and Rich Coombs one hour presentation on Arduino. Some info on Arduino and the talk: Arduino is a hardware and software platform for developing electronic devices and applications, aimed at being fun and accessible to everyone. Think Lego Mindstorms, but aimed intentionally at adults (rather than aimed at children and incidentally used by adults :)). The scope and potential for Arduino is huge. It has been used to develop simple applications like pedometers and networked environmental sensors, to art exhibits and remote controlled vehicles. The talk aims to give an overview of the Arduino platform and a brief introduction to designing and programming Arduino applications, along with some demonstrations.
Arduino Uno is a microcontroller board based on 8-bit ATmega328P microcontroller. Along with ATmega328P, it consists other components such as crystal oscillator, serial communication, voltage regulator, etc. to support the microcontroller. Arduino Uno has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
Arduino is the popular open-source electronics prototyping platform based on easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments and is designed to be as flexible as possible to fit your project's needs.

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. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
DevOps and Testing slides at DASA ConnectKari Kakkonen
My and Rik Marselis slides at 30.5.2024 DASA Connect conference. We discuss about what is testing, then what is agile testing and finally what is Testing in DevOps. Finally we had lovely workshop with the participants trying to find out different ways to think about quality and testing in different parts of the DevOps infinity loop.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
