How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

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?
TROUBLESHOOTING 9 TYPES OF OUTOFMEMORYERRORTier1 app

This session equips you with the knowledge, tools, and techniques needed to troubleshoot and conquer OutOfMemoryError in all its forms, ensuring smoother, more efficient Java applications.
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.

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.
Code reviews are vital for ensuring good code quality. They serve as one of our last lines of defense against bugs and subpar code reaching production.

4. PHP originally stood for:
Personal Home Pages
PHP is now a recursive acronym that stands for:
PHP: Hypertext Preprocessor
PHP. Three letters that together constitute the name of one of the
world’s most popular programming languages for Web
development, the PHP Hypertext Preprocessor. the language is
today in use on over twenty million Web sites and more than a third
of the world’s Web servers
Introduction to PHP
5. What is PHP
PHP is a server-side scripting language, like ASP
PHP scripts are executed on the server
PHP supports many databases (MySQL, Informix,Oracle etc.
PHP is open source and free to download
PHP files many contain text, HTML tags and scripts
PHP files are returned to the browser as plain HTML
PHP supports many databases (MySQL, Informix,Oracle etc.
PHP files have extension of “.php”, “.php3” or “.phtml”
6. History
PHP is a language for creating interactive web sites.
It was originally called "Personal Home Page Tools"
when it was created in 1994 by Rasmus Lerdorf to keep
track of who was looking at his online CV.
Mid-1997: students Andi Gutmans and Zeev Suraski
redesigned the PHP language engine and wrote some of
the most popular PHP modules.
At that time PHP already had its own site, php.net,
run by the computer science community, and was powering
thousands of Web sites.
.
7. These Dates are recent…
Version 0.0: Conceived in autumn of 1994.
Version 1.0: Personal Home Page Tools in early 1995.
Version 2.0: PHP/FI 1995-1997.
Version 3.0: PHP 1997-2000.
Version 4.0: PHP mid-2000.
Version 4.1: 10 Dec 2001.
Version 4.2: 22 Apr 2002.
Version 5.0: 26 February 2009.
.
8. Unique Features
If you’re familiar with other server-side languages like ASP.NET or JSP,
you might be wondering what makes PHP so special, or so different
from these competing alternatives. Well, here are some reasons:
Performance
Scripts written in PHP execute faster than those written in other scripting
languages, with numerous independent benchmarks putting the language
ahead of competing alternatives like JSP, ASP.NET, and Perl.
The PHP 5.0 engine was completely redesigned with an optimized
memory manager to improve performance, and is noticeably faster
than previous versions.
.
9. Unique Features
Portability
PHP is available for UNIX, Microsoft Windows, Mac OS, and OS/2, and
PHP programs are portable between platforms. As a result, a PHP
application developed on, say, Windows will typically run on UNIX without
any significant issues.
Ease of Use
Its syntax is clear and consistent, and it comes with exhaustive
documentation for the 5000+ functions included with the core
distributions.
Open Source
PHP is an open-source project—the language is developed by a
worldwide team of volunteers who make its source code freely
available on the Web, and it may be used without payment of
licensing fees or investments in expensive hardware or software.
10. Unique Features
Third-Party Application Support
One of PHP’s strengths has historically been its support for a wide
range of different databases, including MySQL, PostgreSQL,
Oracle, and Microsoft SQL Server. PHP 5.3 supports more than
fifteen different database engines, and it includes a common API for
database access.
Q: Do I need to compile PHP programs before executing them,
as in Java or C++?
No, because PHP is an interpreted language. One advantage of an
interpreted language is that it allows you to make changes to your
source code and immediately test these changes, without first
needing to compile your source code into binary form. Skipping the
compilation step makes the development process much faster, and
PHP comes with built-in memory management.
11. What you need for PHP?
Install an Apache Server (web server) on a windows or
Linux machine
Install PHP (server side scripting technlogy) on a
windows or Linux machine
Install MySQL (database server) on a windows or Linux
machine
And lots of Configuration work!!!
Alternatively, Just download WAMP Server and install
It will not only installs Apache, MySQL and PHP on windows
machine but will also configure these softwares.
Provides you an easy to access interface to run and host
PHP files.
12. PHP is C++ Style
PHP is very similar to C++.
This is because C++ is top banana.
As a consequence if you know java (also a c++ ), C++ or
indeed almost any other computer science language you pretty
much already know PHP.
However more than anything PHP is based on Perl.
13. PHP Tag Styles
XML Style:
<?php
print “this is XML style”;
?>
Short Style:
<?
print “this is ASP style”;
?>
14. Basic Development Concepts
When developing a PHP application for the Web, the typical
approach is to embed PHP code into one or more standard HTML
documents using special “tags,” or delimiters.
<html>
<head></head>
<body>
<div>
<?php echo sqrt(49); ?>
</div>
</body>
</html>
15. Basic Development Concepts
When such document is requested by a user,a PHP aware Web
Server can recognize and execute the php code blocks and
interpolate the resulting output into html document before returning
it to the requesting user.
16. Writing and Running the Script
PHP scripts are merely plain-text files containing PHP instructions,
sometimes combined with other odds and ends—JavaScript,
HTML, and so on. So, the simplest way to write a PHP script is to
pop open your favorite text editor and create a file containing some
PHP code, as follows:
<?php
// this line of code displays a famous quotation
echo 'A horse! A horse! My kingdom for a horse!';
?>
17. Writing and Running the Script
Save this file to a location under your Web server’s document root,
and name it horse.php. Then, start up your Web browser, and
browse to the URL corresponding to the file location. You should
see something like Figure.
18. Comments
Why do we go on about comments so much?
You can any of the following comment style in php.
<?
// C style comment
# Perl style comment
/*
C++ multi line comment
*/
?>
19. Escaping Special Characters
PHP allows you to escape certain characters by preceding them
with a backslash (). There so-called escape sequences include
Sequence What It Represents
n a line feed character
t a tab
r a carriage return
" a double quotation mark
' a single quotation mark
20. Difference between echo and print
Echo Print
1)can output one or more
strings
1)can only output one
string, and returns always 1
2)echo can take more than
one parameter when used
without parentheses.
2)print only takes one
parameter.
3)In PHP, echo is not a
function but a language
construct.
3)In PHP, print is not a
really function but a
language construct.
However, it behaves like a
function in that it returns a
value.
