To be Continued - multithreading with Project Loom and Kotlin's CoroutinesArtur Skowroński
Both Kotlin and Java are languages that are heavily used in Distributed Systems, handling multiple asynchronous operations simultanouesely. Blocking is not an option in such an environment, but let’s be honest, we crave for easier synchronous world. That’s why JVM as a platform have inherent focus on providing easier option of multithreaded programming. Today, I’d like to compare two of such options - Kotlin Coroutines and Project Loom, that want to provide fibers and continuations to core Java.
This presentation is for those students and IT professionals who have basic programming knowledge and want to learn Perl basics for Pentesting.
We have explained minimal Perl basics which a pentester should know to write,read,modify Perl scripts for Pentesting like data type, comparison operator, loop controls, minimal CPAN modules related to web and networking, perl scripts in Kali and some demo
Steve will show how and why to use Solr’s new Schemaless Mode, under which document indexing can be performed with no up-front schema configuration. Solr uses content clues to choose among a predefined set of field types and then automatically add previously unseen fields to the schema.
Ciąg dalszy nastąpi - o wielowątkowości, Projekcie Loom i kotlinowych KorutynachArtur Skowroński
Zarówno Java, jak i Kotlin są językami często używanymi przy projektowaniu systemów rozproszonych, w których wykonywane jest wiele równoczesnych zdarzeń. Operacje blokujące w tego typu systemach wydają się nie mieć racji bytu - jednocześnie jednak każdy z nas marzy o powrocie do czasów, kiedy mogliśmy pisać synchroniczny, łatwy w zrozumieniu i czytelny kod... "Kiedyś to było". Dlatego też JVM jako platforma naturalnie stara się ułatwiać wygodę używania programowania wielowątkowego. W ramach mojej prezentacji chciałbym porównać dwa nowe podejścia do tego problemu - Kotlin Coroutines i Project Loom, wprowadzający "włókna" (fibers) i kontynuacje do starej dobrej Javy.

Obtain better data accuracy using reference tablesKiran Venna
Data accuracy can be improved tremendously by using reference tables, especially when data is loaded from external files into target tables. Checking the data accuracy of source tables can be easily done with help of reference tables. By using SAS® macro,
data accuracy for many files can be performed with a single reference table. Step by step approach to build reference tables and a way to automate the data accuracy
checks will be discussed in this paper.
Algorithm and Programming (Introduction of dev pascal, data type, value, and ...Adam Mukharil Bachtiar
This file contains explanation about introduction of dev pascal, data type, value, and identifier. This file was used in my Algorithm and Programming Class.
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.
Yet, they often turn into annoying tasks riddled with frustration, hostility, unclear feedback and lack of standards. How can we improve this crucial process?
In this session we will cover:
- The Art of Effective Code Reviews
- Streamlining the Review Process
- Elevating Reviews with Automated Tools
By the end of this presentation, you'll have the knowledge on how to organize and improve your code review proces

Paketo Buildpacks : la meilleure façon de construire des images OCI? DevopsDa...Anthony Dahanne
Les Buildpacks existent depuis plus de 10 ans ! D’abord, ils étaient utilisés pour détecter et construire une application avant de la déployer sur certains PaaS. Ensuite, nous avons pu créer des images Docker (OCI) avec leur dernière génération, les Cloud Native Buildpacks (CNCF en incubation). Sont-ils une bonne alternative au Dockerfile ? Que sont les buildpacks Paketo ? Quelles communautés les soutiennent et comment ?

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?

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.
