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.
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.

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?
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

2. What is a QR Code?
QR Code Data Capacity:
Numeric Code = 7,089 characters max
Alphanumeric code = 4,296 characters max
“Quick Response”
Introduction
3. Genesis of QR Code
QR codes were first created back in 1994.
A Toyota subsidiary named Denso Wave developed the
code in order to help in the manufacturing process,
they aided in tracking vehicles and parts.
It was designed to allow for fast decoding speeds,
hence the name Quick Response code.
4. QR Codes: Structure
QR code is a type of barcode but it is two dimensional
(vertical and horizontal) code.
A QR code encodes four types of data – (i) numeric (ii)
alphanumeric (iii) binary/bytes and (iv) Kanji (Chinese
characters used in Japan) or mixture of these.
Ability of holding information is much more in a QR code
than a normal barcode.
6. QR Code and Barcode
QR Code Barcode
Contain data horizontal and
vertical direction.
Contain data horizontal direction
Recordable data size large Recordable data size small
Area size small Area size greater than QR code
Smartphone compatible Barcode scanner is needed.
7. Basic Requirements
A specific reader device or a Mobile Phone with
a camera and Internet Access
Software to Decode
10. Steps to Build QR Code
1. Importing the Modules
2. Creating the main window
3. Taking the input of the text/URL, location to store
the QR code, name of the QR code and the size of
the QR code
4. Writing the function to generate and save the QR
Code
11. QR Codes: Advantages
Recordable data size in QR codes is large;
QR codes are smartphone compatible;
Low cost and easy to implement;
QR code has error correction capability upto 30%;
Directly navigation to a website or phone number
without typing them;
Small Printout Size;
Readable from 360o
12. QR Codes: limitations
Not everyone is aware of QR code;
Not everyone owns a smartphone and many cell
phones do not include a QR code reader, the software
must be downloaded and tested;
The small screens of a mobile or PDA limits the
amount and type of information that can be displayed
at a given time;
Before scanning a code, users never really know where
the code is going to direct them.
13. QR Codes: Application
Promotional landing pages and entry forms
E-commerce shopping sites
Product demos, videos and reviews
Virtual business cards
14. Conclusion
In general, we believe that QR codes have great potential in business
media.
We examine outlined the dangers of possible malicious attacks
utilizing manipulated QR Codes.
Since QR Codes gain increasing popularity through their use for
marketing purposes, we expect that this kind of attack will receive
more and more attention by the hacking community in the future.
This project will present some security conscious of the mobile phones
users.
15. Future Work
The main limitation of QR codes is that they are only being used to redirect
to a webpage or website but they are not collecting any information on their
own.
If in this hugely data driven world, if these codes start to collect
information and start a two-way transaction then it will surely stabilize in
this technology market for future years.
Another limitation regarding the application of QR codes is that one must
have a QR code reader or scanner installed in their mobile or tablet to be
able to scan and read the data held by the QR code.
Instead of this, we can create and integrate the QR code scanners in our
smartphone’s camera itself so that we don’t need any other third party
application to scan the QR codes.
QR codes have been scrutinized by many of the technology and security
pundits but still it has been loved and accepted by the normal people at a
high context.
