The chemicals industry (industrial chemicals, pharmaceuticals, pesticides, biocides, food and feed additives and cosmetics) is one of the largest industrial sectors in the world and one which poses many challenges for government regulators; inefficient regulation would have costly implications for the environment, human health, government budgets and the continued growth of this important global industry. Not only can different regulatory approaches and requirements in each OECD country create significant costs for the chemicals industry and for governments, they can also create barriers to trade.
If national approaches to chemical regulation are harmonised, industry is not faced with a plethora of conflicting or duplicative requirements, governments are provided with a common basis for working with each other, and non-tariff barriers to trade are reduced. The principal tools for harmonisation are a set of OECD Council Decisions which make up the OECD Mutual Acceptance of Data (MAD) system, including its OECD Guidelines for the Testing of Chemicals and OECD Principles of Good Laboratory Practice (GLP).

"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.

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.

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.

8. What Is Android?
Google’s Andy Rubin describes Android as:
The first truly open and comprehensive platform for mobile devices, all of the
software to run a mobile phone but without the proprietary obstacles that have
hindered mobile innovation.
(http://googleblog.blogspot.com/2007/11/wheres-mygphone.html)
9. What Is Android?
A software platform and operating system for mobile devices
Based on the Linux kernel
Developed by Google and later the Open Handset Alliance (OHA)
Allows writing managed code in the Java language
Possibility to write applications in other languages and compiling it to
ARM native code (support of Google? No)
Unveiling of the Android platform was announced on 5 November 2007
with the founding of OHA
10. What Is Android?
Android is made up of several necessary and dependent parts :
A hardware reference design.
A Linux operating system kernel.
Open-source libraries for application development.
A run time used to execute and host Android applications.
An application framework.
A user interface framework.
Preinstalled applications.
A software development kit.
12. Security
Android is a multi-process system, in which each application (and parts of the
system) runs in its own process. Most security between applications and the
system is enforced at the process level through standard Linux facilities, such as
user and group IDs that are assigned to applications.
Additional finer-grained security features are provided through a "permission"
mechanism that enforces restrictions on the specific operations that a particular
process can perform, and per-URI permissions for granting ad-hoc access to
specific pieces of data.
13. Future possibilities
Google Android Sales to Overtake iPhone in 2012
The OHA is committed to make their vision a reality: to deploy the Android
platform for every mobile operator, handset manufacturers and developers to
build innovative devices
Intel doesn’t want to lose ownership of the netbook market, so they need to
prepare for anything, including Android
Fujitsu launched an initiative to offer consulting and engineering expertise to
help run Android on embedded hardware, which aside from cellphones,
mobile internet devices, and portable media players, could include GPS
devices, thin-client computers and set-top boxes.
More Android devices are coming and some will push the envelope even
further

20. Android Software Stack
Linux kernel :
This is the kernel on which Android is based. This layer contains all the
low-level device drivers for the various hardware components of an Android
device
Libraries :
A media library for playback of audio and video media
A surface manager to provide display management
Graphics libraries that include SGL and OpenGL for 2D and 3D graphics
SQLite for native database support
SSL and WebKit for integrated web browser and Internet security
21. Android Software Stack
Android run time :
Core libraries : provide most of the functionality available in the
core Java libraries as well as the Android-specific libraries.
Dalvik virtual machine : a register-based virtual machine that’s
been optimized to ensure that a device can run multiple instances
efficiently.
Application framework :
Exposes the various capabilities of the Android OS to application
developers so that they can make use of them in their applications.
Applications :
you will find applications that ship with the Android device(such as
Phone, Contacts, Browser, etc.), as well as applications that you download
and install from the Android Market. Any applications that you write are
located at this layer
22. The Dalvik Virtual Machine
All applications written in Java and converted to the dalvik executable
.dex
Every android app runs its own process, with its own instance of the
dalvik virtual machine.
Not a traditional JVM, but a custom VM designed to run multiple
instances efficiently on a single device.
VM uses linux kernel to handle low-level functionality incl. security,
threading, process and memory management.
23. Android Application Architecture
Rich, extensible set of Views
apps can includes lists, grids, text boxes, buttons, web browser
Content Providers
allows data access from other applications or share own data
Resource Manager
access to localized strings, graphics, layout files
Notification Manager
enables custom alerts to be displayed in status bar
Activity Manager
Manages lifecycle of applications and provides navigation
backstack
24. Application Fundamentals
Activities
application presentation layer
Services
invisible components, update data sources, visible activities, trigger notifications
perform regular processing even when app is not active or invisible
Content Providers
shareable data store
Intents
message passing framework
broadcast messages system wide, for an action to be performed
Broadcast receivers
consume intent broadcasts
lets app listen for intents matching a specific criteria like location
Notifications
➤ Toast notification ➤ Status Bar Notification ➤ Dialog notification
25. Applications
All apps (native and 3rd party) are written using the same APIs and run
on the same run time executable
All apps have APIs for hardware access, location-based services,
support for background services, map-based activities, 2D and 3D
graphics.
App Widgets are miniature app views that can be embedded in other
apps like Home Screen
26. App Priority and Processes
Android apps do not have control over their own life cycles.
Aggressively manages resources to ensure device responsiveness and
kills process/apps when needed.
Active Process – critical priority.
Visible Process – high priority.
Started Service Process.
Background Process – low priority.
Empty process.
27. Compatibility

libraries use either hardware 3D acceleration (where available) or the
included, highly optimized 3D software rasterizer
FreeType - bitmap and vector font rendering
SQLite - a powerful and lightweight relational database engine available
to all applications
31. The Android market
Google Market - Part of GMS apps
3rd party apps submitted to Google, approved and distributed through
Market.
Both Free and Paid apps.
Apps now limited to 50 MB; updates possible through Market
Monetization through ads available.
Available in many countries, not all countries have support for paid
apps.
Other Market place applications available – Amazon has announced
its own Android Market place.
App searches filtered based on Manifest file (eg. if a device does not
have trackball, apps using trackball will be filtered out).
Every app publishes a list of components the app will access and
permissions need to be granted before installation.
Apps installed on device and SD card (SD Card from Froyo).
33. Android vs. J2ME
Multiple device configurations
J2ME has 2 classes of micro devices
Android offers only one
Ease of understanding
J2ME has multiple UI model (MIDlets, Xlets, AWT, Swing …)
Android support for only one, so it would be more easier to understand
than J2ME
34. Android vs. J2ME
Responsiveness
Dalvik VM vs. JVM
Dalvik VM vs. KVM
Java compatibility
Android runs .dex bytecode
Runtime interpretation of Java bytecode is not possible
35. Android vs. J2ME
Adoption
Most of mobile phone support for J2ME
But uniformity, cost, ease of development in Android are the reasons
for java developer to program for it
Java SE support
Android support for J2SE more complete than J2ME CDC (except
AWT & Swing)
36. Apple vs. Android
Games 52.2% of app sales in 2010
350K apps in iStore, 130K in Android market (294K in may)
Android easiest to write for
Tools plus getting published
