Software Development Best Practices: Separating UI from Business LogicICS
One of the most effective software engineering approaches involves separating the user interface (frontend) from the business logic (backend), especially when it comes to developing embedded-devices. This practice makes it far easier to code for a single specific functionality versus coding an overall product.
In this webinar we’ll explain not only what’s involved in separating the UI from business logic in your next Qt project, but explore some of the key benefits of this approach, including:
Parallel development
Modularity
Enhanced testability
Accelerated development
Architecture that easily accommodates future changes
We’ll also touch on a few of the drawbacks, chief among them the need to implement new strategies for independent testing, build and deployment — tasks that take extra time and resources

MDG Panel - Creating Expert Level GUIs for Complex Medical DevicesICS
Graphical User Interfaces are so pervasive and have so many different design intents that it can be hard to see the norms and evolution of norms being applied over the past couple of decades. In medical devices, more than most, tradeoffs between safety, effectiveness and pleasure-to-use, dominate the design efforts.
.
Much focus and debate has been applied to paradigms of “simple yet effective” in GUI design. The most commonly cited ideals in the Apple eco-system and skeuomorphic design concern themselves with the novice user and technology adoption. But not all products are designed for the novice user.
.
For UIs that expose advanced or unstructured feature sets to the user, the normative approach has been to compromise on the simplicity to extend the functionality. But such an approach can be incremental and muddled where a better approach might be cogent redesign.
.
We will explore the evolution of a life-saving lung transplant medical device from Tevosol that implements an expert-level GUI for clinical users. Focus will be on lessons learned and the design principles ultimately chosen.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

A Comprehensive Look at Generative AI in Retail App Testing.pdfkalichargn70th171
Traditional software testing methods are being challenged in retail, where customer expectations and technological advancements continually shape the landscape. Enter generative AI—a transformative subset of artificial intelligence technologies poised to revolutionize software testing.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

What is Qt for Python?
• Also known as PySide 2
• Qt for Python are the Python v2 and v3 bindings for Qt
• Qt for Python gives the Python programmer access to the full Qt API
• API is the same from C++
• Qt for Python is available under the LGPL v3 and the Qt Commercial License.
• Owned and distributed by The Qt Company
2
3. Integrated Computer Solutions Inc. www.ics.com
Other Features
• The APIs are almost identical to C++, so experienced Qt users can quickly get
up to speed and leverage their Qt knowledge.
• You can continue to use Qt Designer .ui files and resources.
• If you are porting a C++ application, you can mostly one for one port much of
the code.
• Run time errors are usually straightforward.
• A developer can be very productive due to not needing a compile/build cycle.

Confusion with PyQt
• PyQt is another product that provides Python bindings to Qt (and is mostly
compatible with PySide)
• PyQt is dual licensed on all supported platforms under the GNU GPL v3 and
the Riverbank Commercial License (LGPL not available)
• PyQt is owned and distributed by Riverbank
• Differences between Python for Qt and PyQt are discussed here:

What is Qt?
• Cross-Platform C++ class library
• Encompasses some 1,500 C++ classes
• Started as a Graphics User Interface (GUI) toolkit
• Is much more today: Threads, XML/JSON parsing, Regular Expressions, Sockets, HTML parsing
• Development for Desktop and Embedded Devices
• Qt is available under commercial and open source licenses
• In addition to class libraries, Qt framework contains several tools, like Qt Creator (IDE), Qt Designer,
qmake, Qt Linguist
• Owned and distributed by The Qt Company

Some Notes to Keep in Mind
• No QString, use Python string (str)
• The Qt container classes are not available, use the ones provided by Python
• Some Qt method names Qt names have had an underscore appended to
resolve this conflict (i.e. QTextStream methods bin_(), hex_(), oct_() and
QDialog exec_())
• No QVariants! Any Qt function expecting or returning a QVariant can receive
or return any Python object

When to Use Non-GUI PySide 2
• Dealing with not blocking your GUI (QProcess, networking, QSerial vs.
PySerial, etc.)
• QSqlDatabase because you want to show it in a QTableView
• Better integration with Qt in general (e.g. QThread)
