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.

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.

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.
3. What is Raspberry pi
Credit card sized computer with incredible features
SOC HDMI ETHERNET
GPIO
4. USP?
Model A = $25
Model B = $35
Uses low power SOC (System on Chip) Broadcom
BCM2835
BCM2835 supports applications from word
processing, web-browsing to 3D gaming
Linux OS
Industry standard for prototyping IOT applications
We’re excited to announce that we are expanding our Windows
Developer Program for IoT by delivering a version of Windows 10
that supports Raspberry Pi 2 -Microsoft
5. Brains of PI
ARM1176JZF is the central nervous system of PI
This means any language that can compile on
ARMv6 can be used with raspberry pi
6. Features of PI
SOC powerful enough to easily render
opengl 3D graphics, games and other
multimedia applications
512 MB of ram
Low power consumption (micro USB few
watts)
Built in support for Camera module
40 GPIOs
4 USB ports
Audio output
SD card (primary storage device)
8. What is a GPIO?
A GPIO is a terminal for electronic
signals which can act as source or
sink of signals.
Signals may be both control as well as
data signals
Plays an important role in automation
applications
Python package required to use GPIO
from raspberry pi
sudo apt-get install python-RPi.GPIO
9. BCM vs Board-mode
Board mode means to refer to the pin-
number via it’s position on the board
starting from 1-40
In BCM mode we refer to the pin
names rather than by numbers. It is
based on Broadcom SOC channel
number
10. Words of Caution !!
While working with GPIO it is
important to keep in mind that they are
directly connected to the micro-
processor
Means NO overhead protection
If a high current/voltage signal is
applied to the pin, It may burn the PI
13. For windows and linux users
Download the zip file and extract the OS image
Insert sd card in the sd card reader
Use Win32DiskImager to write to the sd card
Detailed instructions can be found on the raspberry pi
website:
http://www.raspberrypi.org/documentation/installati
on/installing-images/windows.md
For Linux Users:
http://www.raspberrypi.org/documentation/installati
on/installing-images/linux.md
Caution: Linux users should be very careful with
the use of DD command.
14. NOOBS Project
“New Out Of The Box Software” for beginners
It gives you the options to choose from different
operating systems
Download NOOBS zip file and extract it
Format SD card and “drag/drop files into it”
On first boot we see a screen like this
15. For Lazy Coders
Perhaps the most easy way to get
started with Raspberry PI
Buy an SD card with NOOBS pre-
installed and plug it into the pi
Saves you a lot of time if you are more
concerned about app development
16. Monitor, mouse and keyboard
Raspberry pi supports High Definition
video output through HDMI port
We can use our HD TV as a monitor
for raspberry pi
Raspberry pi has 4 usb ports and any
2 can be used to connect a mouse
and a keyboard
17. I can’t take LED with me all the
time
Relax we have a solution !!
Now edit the IPv4 settings in windows
also So they are both in same local
network
Edit: /etc/network/interfaces
18. SSH into your pi
Use an ssh client e.g. PUTTY
ssh pi@192.168.137.10
Enter the password of your raspberry
pi
Start Exploring
