Bryan Murphy's presentation from the 2nd Chicago Docker meetup on March 12, 2014 at Mediafly HQ. In his presentation, Bryan explains how we use Docker right now at Mediafly in production.
Create Disposable Test Environments with Vagrant and PuppetGene Gotimer
As the pace of development increases, testing has more to do and less time in which to do it. Software testing must evolve to meet delivery goals while continuing to meet quality objectives. Gene Gotimer explores how tools like Vagrant and Puppet work together to provide on-demand, disposable test environments that are delivered quickly, in a known state, with pre-populated test data and automated test fixture provisioning. With a single command, Vagrant provisions one or more virtual machines on a local box, in a private or public cloud. Puppet then takes over to install and configure software, setup test data, and get the system or systems ready for testing. Since the process is automated, anyone on the team can use the same Vagrant and Puppet scripts to get his own virtual environment for testing. When you are finished with it, Vagrant tears it back down and restores it to the same original state.
At the moment, cloud CI systems are a highly-demanded service. In this article, we'll tell you how to integrate analysis of source code into a CI cloud platform with the tools that are already available in PVS-Studio. As an example we'll use the Travis CI service.

We have evolved Research Objects as a mechanism to preserve digital resources related to research, by providing mechanisms, formats and architecture for describing aggregated resources (hypothesis, workflow, datasets, scripts, services), their relations (is input for, explains, used by), provenance (graph was derived from dataset A, B and C) and attribution (who contributed what, and when?).
The website myExperiment is already popular for collaborating on, publishing and sharing scientific workflows, however we have found that for understanding and preserving a workflow over time, its definition is not enough, specially faced with workflow decay, services and tools that change over time. We have therefore adapted the research object model as a foundation for the myExperiment packs, allowing uploading of workflow runs, inputs, outputs and other files relevant to the workflow, relating them with annotations and integrated the Wf4Ever architecture for performing decay analysis and tracking a research object’s evolution as it and its constituent resources change over time.

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.

Each type of OutOfMemoryError has different causes, diagnosis approaches and solutions. 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.
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.

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.

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.

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?

26. The Apache WayThe Apache Way
Community over Code
Open:
If it didn't happen on the mailing list, it didn't happen
Everybody has a say
Merit - win by doing it
Personal merit - not organizational
27. Community developmentCommunity development
Users and Developers
..are they really separate?
Ask not what can I do for the user,
but what can the user do for me
Give teasers to potential committers
"I think the problem is somewhere in this file"
... without saying "You're on your own, mate"!
Recognize any contributions, not just code
Docs, training, examples, help, discussions, ...

32. Transitioning to ApacheTransitioning to Apache
Moving all infrastructure:
Mailing lists, Source code repositories, wiki,
issue tracker, web pages
GitHub pull request workflow
integrated with mailing list
All transitioning discussed in public
..might scare people :-(
34. Is moving easy?Is moving easy?
Depends..
Taverna - lots of infrastructure
Jira w/1000s of old and new issues,
Wordpress,
30 GitHub repositories
months
Commons RDF: Single GitHub repository, GitHub pages.

35. ConclusionsConclusions
ASF gives strong template for community building
.. and initial bureaucracy :-(
Worth it in the long run!
Licensing is boring, but necessary
Mentors are kind and helpful
Community building takes effort
Community growth is fun
Giving up "control" gives peace and openness
36. Is Apache fit for my project?Is Apache fit for my project?
It's not your project, but your community's project!
So your existing community should decide
Find a champion from an existing Apache project
Are you ready for Open Development?
Are you already there?
Do you have time to guide the community
towards "the Apache Way"?
Apache not a magic bullet
You still need to do the work!
