The document discusses how C++ has evolved from its origins as "C with classes" to a modern, expressive language with features like lambda expressions, smart pointers, templates, parallel programming support, and type inference. It provides examples of new C++11, C++14, and C++17 language features and core library additions like std::variant and std::optional that have enhanced performance, expressiveness and quality of life. The document suggests C++ has transformed from its original form and aims to demonstrate how modern C++ code looks different than older styles through examples. It closes by speculating on future C++ features like concepts, ranges and reflection.

Debugging and Profiling C++ Template MetaprogramsPlatonov Sergey
Template metaprogramming is an emerging new direction in C++ programming for executing algorithms in compilation time. Despite all of its already proven benefits and numerous successful applications, it is yet to be accepted in industrial projects. One reason is the lack of professional software tools supporting the development of template metaprograms. A strong analogue exists between traditional runtime programs and compile-time metaprograms. This connection presents the possibility for creating development tools similar to those already used when writing runtime programs. This paper introduces Templight, a debugging framework that reveals the steps executed by the compiler during the compilation of C++ programs with templates. Templight’s features include following the instantiation chain, setting breakpoints, and inspecting metaprogram information. This framework aims to take a step forward to help template metaprogramming become more accepted in the software industry.
Just how different is "Modern C++" from "legacy C++"? Is my codebase ready for C++17? Do I need a full rewrite of my app to modernize my code? If you're looking for answers to some of these questions, join us for a session on how to effectively leverage modern C++17 features in your existing C++ projects; and no, you don't need to rewrite your app.
C++ Code as Seen by a Hypercritical ReviewerAndrey Karpov

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Exploring Innovations in Data Repository Solutions - Insights from the U.S. G...Globus
The U.S. Geological Survey (USGS) has made substantial investments in meeting evolving scientific, technical, and policy driven demands on storing, managing, and delivering data. As these demands continue to grow in complexity and scale, the USGS must continue to explore innovative solutions to improve its management, curation, sharing, delivering, and preservation approaches for large-scale research data. Supporting these needs, the USGS has partnered with the University of Chicago-Globus to research and develop advanced repository components and workflows leveraging its current investment in Globus. The primary outcome of this partnership includes the development of a prototype enterprise repository, driven by USGS Data Release requirements, through exploration and implementation of the entire suite of the Globus platform offerings, including Globus Flow, Globus Auth, Globus Transfer, and Globus Search. This presentation will provide insights into this research partnership, introduce the unique requirements and challenges being addressed and provide relevant project progress.
Listen to the keynote address and hear about the latest developments from Rachana Ananthakrishnan and Ian Foster who review the updates to the Globus Platform and Service, and the relevance of Globus to the scientific community as an automation platform to accelerate scientific discovery.
In the ever-evolving landscape of technology, enterprise software development is undergoing a significant transformation. Traditional coding methods are being challenged by innovative no-code solutions, which promise to streamline and democratize the software development process.
This shift is particularly impactful for enterprises, which require robust, scalable, and efficient software to manage their operations. In this article, we will explore the various facets of enterprise software development with no-code solutions, examining their benefits, challenges, and the future potential they hold.
We describe the deployment and use of Globus Compute for remote computation. This content is aimed at researchers who wish to compute on remote resources using a unified programming interface, as well as system administrators who will deploy and operate Globus Compute services on their research computing infrastructure.

Enhancing Research Orchestration Capabilities at ORNL.pdfGlobus
Cross-facility research orchestration comes with ever-changing constraints regarding the availability and suitability of various compute and data resources. In short, a flexible data and processing fabric is needed to enable the dynamic redirection of data and compute tasks throughout the lifecycle of an experiment. In this talk, we illustrate how we easily leveraged Globus services to instrument the ACE research testbed at the Oak Ridge Leadership Computing Facility with flexible data and task orchestration capabilities.
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.

84. Here’s my personal litmus test for whether
we’ve changed the way people program: Just
as you can take a look at a screenful of code
and tell that it’s C++11 (not C++98), if you
can look at a screenful of code and tell that
it’s C++17, then we’ve changed the way we
program C++. I think C++17 will meet that
bar.
