Elasticsearch is well known as a highly scalable search engine that stores data in a structure optimized for language based searches but its capabilities and use cases don't stop there. In this tutorial, I'll give you a hands-on introduction to Elasticsearch and give you a glimpse at some of the fundamental concepts.
Database administration is challenging, and Elasticsearch is not an exception to that rule. In this tutorial, we will cover various administrative topics like Installation and Configuration, Cluster/Node management, Indexes management and Monitoring Cluster Health which will help you. Building applications on top of an Elasticsearch are also challenging and raise concerns about schema design. In this tutorial, we will cover developer-oriented topics like Mappings and Analysis, Aggregations and Schema Design that will help you build a robust application on top of Elasticsearch.
There will be lab sessions at the end of some chapters so please have your laptops with you.
For Elasticsearch users, backups are done using the Elasticsearch snapshot facility. In this presentation I'll go through the design of an Elasticsearch backup system that you can use to create snapshots of your cluster's indices and documents.
Java in 2019 was predicted to be business as usual by many. We have seen new Java releases coming out as planned, AdoptOpenJDK became the main trustful source of binaries and Oracle fighting for the trademark again by preventing the use of javax as namespace. Everything looks like it would be a silent year for Java. But one thing seems obvious. Java's popularity is not gaining any more traction. New language features keep it up to date but people are getting more selective when it comes to implementation choices. Especially in the age of containers and cloud infrastructures. This talk walks you through the why and how of Java in containers. We will talk about image size and development and deployment processes.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.
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.
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.
A Comprehensive Look at Generative AI in Retail App Testing.pdfkalichargn70th171

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.
Globus Connect Server Deep Dive - GlobusWorld 2024Globus

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?
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.

SOCRadar Research Team: Latest Activities of IntelBrokerSOCRadar
The European Union Agency for Law Enforcement Cooperation (Europol) has suffered an alleged data breach after a notorious threat actor claimed to have exfiltrated data from its systems. Infamous data leaker IntelBroker posted on the even more infamous BreachForums hacking forum, saying that Europol suffered a data breach this month.
The alleged breach affected Europol agencies CCSE, EC3, Europol Platform for Experts, Law Enforcement Forum, and SIRIUS. Infiltration of these entities can disrupt ongoing investigations and compromise sensitive intelligence shared among international law enforcement agencies.
However, this is neither the first nor the last activity of IntekBroker. We have compiled for you what happened in the last few days. To track such hacker activities on dark web sources like hacker forums, private Telegram channels, and other hidden platforms where cyber threats often originate, you can check SOCRadar’s Dark Web News.

4. Agenda
• A very quick overview of Galera Cluster
• Adding the Galera package repository
• Installing packages
• Creating a configuration file
• Bootstrapping a 3-node cluster
• Monitoring
5. Galera Cluster Overview
Synchronous
– each transaction is immediately replicated on all nodes at commit
– no stale slaves
Multi-Master
– read from and write to any node
– automatic transaction conflict detection
Replication
– a copy of the entire dataset is available on all nodes
– new nodes can join automatically
For MySQL
– based on a modified version of MySQL (5.5, 5.6 with 5.7 coming up)
– InnoDB storage engine
6. And more …
• Recovers from node failures within seconds
• Data consistency protections
– avoids reading stale data
– prevents unsafe data modifications
• WAN support
– nodes can be on different continents
– end-to-end encryption
– optimized communication with least latency
7. Package Installation (CentOS, RHEL)
1. Remove existing MySQL server packages
2. Configure the Galera Cluster repository
Add a .repo file in /etc/yum.repos.d/:
[galera]
name = Galera
baseurl = http://releases.galeracluster.com/centos/7/x86_64
gpgkey = http://releases.galeracluster.com/GPG-KEY-galeracluster.com
gpgcheck = 1
(note distribution name and release number are specified)
1. Install Galera Cluster Packages
yum –y upgrade mysql-wsrep-shared-5.6
yum –y install galera-3 mysql-wsrep-5.6
8. Preparing the System
• Nodes should have identical hardware
• Firewall ports to open:
3306, 4567, 4568, 4444
• Disable SELinux
– a policy can be created and enabled later
9. The my.cnf Configuration File
• All Galera configuration is in my.cnf
• Keep the my.cnf files on all nodes identical
• InnoDB settings are important
optimize individual nodes as you normally would:
– InnoDB buffer size
– InnoDB log file size
• Galera-specific settings:
default_storage_engine=InnoDB
binlog_format=ROW
innodb_autoinc_lock_mode=2
wsrep_provider=/usr/lib64/galera-3/libgalera_smm.so
wsrep_cluster_address="gcomm://node1,node2,node3... "
10. Bootstrap
1. Start first node with –wsrep-new-cluster:
sudo service mysql start --wsrep-new-cluster
1. Confirm a single-node cluster:
SHOW STATUS LIKE 'wsrep_%'
| wsrep_cluster_status | Primary |
| wsrep_cluster_size | 1 |
1. Start all other nodes normally
sudo service mysql start
1. Confirm nodes have joined:
SHOW STATUS LIKE 'wsrep_%'
| wsrep_cluster_size | 3 |
11. Monitoring
Traditional MySQL monitoring methods are used:
• SHOW STATUS
• SHOW PROCESSLIST
• The MySQL error log
– all Galera messages go there
• Queries against INFORMATION_SCHEMA
12. SHOW STATUS
• Node health variables:
– wsrep_ready = ON
– wsrep_cluster_size
– wsrep_cluster_status = Primary
– wsrep_local_status = Synced
• Replication health variables:
– wsrep_flow_control_paused < 0.05
– wsrep_local_bf_aborts + wsrep_local_cert_failures
(do not forget periodic FLUSH STATUS)
13. SHOW PROCESSLIST
• Queries to watch out for:
– long “Query end” phase
• replication takes place during that phase
– long-running DDL
• under default settings may block cluster
14. INFORMATION_SCHEMA
• Avoid non-InnoDB tables:
SELECT TABLE_SCHEMA, TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE ENGINE != 'InnoDB'
AND TABLE_SCHEMA NOT IN ('mysql','performance_schema',
'information_schema');
• Avoid tables with no primary key:
SELECT T.TABLE_SCHEMA, T.TABLE_NAME
FROM information_schema.tables AS T
WHERE (table_schema, table_name)
NOT IN (SELECT table_schema, table_name
FROM information_schema.table_constraints AS C
WHERE T.table_name = C.table_name
AND T.table_schema = C.table_schema )
AND table_schema NOT IN
('mysql','information_schema','performance_schema');
