The open source Node-RED system provides a data flow programming tool for IoT applications, but is limited to executing a single flow description in a single threaded event loop. In this paper we describe the design of our system called the Front-End for Node-RED (FRED) that manages multiple instances of Node-RED for logged in users, allowing Node-RED to be used without modification as a cloud-hosted data flow mashup tool for the IoT. We present some examples of how some of our 1800+ users are using FRED for IoT mashups, some of the challenges we faced in implementing the FRED system, and future directions for FRED.
This presentation was given at the GlobusWorld 2020 Virtual Conference, by Ian Foster, Rachana Ananthakrishnan, and Vas Vasiliadis from the University of Chicago.

Building Continuous Application with Structured Streaming and Real-Time Data ...Databricks
One of the biggest challenges in data science is to build a continuous data application which delivers results rapidly and reliably. Spark Streaming offers a powerful solution for real-time data processing. However, the challenge remains in how to connect them with various continuous and real-time data sources, guaranteeing the responsiveness and reliability of data applications.
In this talk, Nan and Arijit will summarize their experiences learned from serving the real-time Spark-based data analytic solutions on Azure HDInsight. Their solution seamlessly integrates Spark and Azure EventHubs which is a hyper-scale telemetry ingestion service enabling users to ingress massive amounts of telemetry into the cloud and read the data from multiple applications using publish-subscribe semantics.
They’ll will cover three topics: bridging the gap of data communication model in Spark and data source, accommodating Spark to rate control and message addressing of data source, and the co-design of fault tolerance Mechanisms. This talk will share the insights on how to build continuous data applications with Spark and boost more availabilities of connectors for Spark and different real-time data sources.

DYNAMIC ALLOCATION METHOD FOR EFFICIENT LOAD BALANCING IN VIRTUAL MACHINES FO...acijjournal
This paper proposes a Dynamic resource allocation method for Cloud computing. Cloud computing is a model for delivering information technology services in which resources are retrieved from the internet through web-based tools and applications, rather than a direct connection to a server. Users can set up
and boot the required resources and they have to pay only for the required resources. Thus, in the future providing a mechanism for efficient resource management and assignment will be an important objective of Cloud computing. In this project we propose a method, dynamic scheduling and consolidation mechanism that allocate resources based on the load of Virtual Machines (VMs) on Infrastructure as a service (IaaS). This method enables users to dynamically add and/or delete one or more instances on the basis of the load and the conditions specified by the user. Our objective is to develop an effective load balancing algorithm using Virtual Machine Monitoring to
maximize or minimize different performance parameters(throughput for example) for the Clouds of
different sizes (virtual topology de-pending on the application requirement).
This presentation covers both the Cloud Foundry Elastic Runtime (known by many as just "Cloud Foundry") as well as the Operations Manager (known by many as BOSH). For each, the main components are covered with interactions between them.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

2. BOINC (Berkeley Open Infrastructure for Network Computing) What is BOINC? BOINC is middleware system created to simplify the implementation of volunteer computing projects. What is volunteer computing? Volunteer computing is an arrangement in which people (volunteers) provide internet-connected computers, to be used as a source of computing power and storage. Why use volunteer computing? Volunteer computing uses computational resources that would otherwise be unused, to solve computationally intensive projects, for lower costs them other available solutions.
3. Task Server Components Each BOINC-based projects operates a server consisting of several components: Web interfaces for account and team management, message boards, and other features. A task server that creates tasks dispatches them to clients, and processes returned tasks. A data server that downloads input files and executables, and that uploads output files. The clients periodically communicates with the task server to report completed work and to get new work.
4. Task Server Components What are the functions of the programs? The work generatorprepares new jobs to be sent and their input files. The scheduler deals requests from the clients. The requests include a description of the host, a list of completed instances, and a request for additional work. The reply includes a list of instances and their corresponding jobs. The scheduler also maintains the records for the user account and team, the host, and the various jobs and instances The feederfacilitates the scheduler’s database access, maintaining a shared-memory segment containing static database tables, and a fixed-size cache of unsent instance/job pairs. The transitionerexamines jobs for which a state change has occurred if needed generates new instances, flag the job as having a permanent error, or trigger validation or assimilation of the job.
5. Task Server Components The validatorcompares the instances of a job and selects a canonical instance representing the correct output. It determines the credit granted to users and hosts that return the correct output, and updates those database records. The assimilatorhandles job that are “completed” (has an canonical instance or a permanent error has occurred). Handling a successfully completed job might involve writing outputs to an application database or archiving the output files. The file deleterdeletes input and output files that are no longer needed. The database purgerremoves jobs and instance database entries that are no longer needed, first writing them to XML log files. The programs communicate using the BOINC database.
6. Persistent redundant computing Because incorrect output may result from a hardware and software problems, an incorrect modification to the application, or a intentional attack by the volunteer, mechanisms to ensure that outputs are correct (validation)and that tasks eventually get done (retry). BOINC provides a mechanism called persistent redundant computing that accomplishes both goals. This mechanism involves performing each task independently on various computers, comparing the outputs, looking for a “quorum” of equivalent outputs, and generating new instances as needed to reach a quorum.
7. How The Magic is done Client Side Core Client Client has 2 “modes” Manager Screensaver
9. How The Magic is done Client Side The core client communicates with applications by shared-memory message passing
10. Failure Protection BOINC uses heartbeat messages BOINC API finalization routine writes a ‘finished file’ BOINC supplies a set of printf()-replacement functions that buffer output in memory, and flush these buffers during checkpoint All information about a task (exit code, signal number, standard error output, volunteer host platform) is stored in a relational database on the server
11. Conclusion, Death, Taxes and BOINC What is the internet for the average Portuguese user google.pt hi5.com youtube.com live.com google.com Additional info 11 travian.pt 13 facebook.com 14 record.pt 19 abola.pt Source http://www.alexa.com/topsites/countries/PT
12. Conclusion, Why use Boinc Suppose you need a lot of computing power - say, 100 TeraFLOPS for 1 year. Here are some ways you can get it: Use Amazon's Elastic Computing Cloud $175 Million: Based on $0.10 per node/hour. Build a cluster $12.4 Million: This includes power and air-conditioning infrastructure, network hardware, computing hardware, storage, electricity, and sysadmin personnel. Use BOINC $125,000: Based on the average throughput and budget of the 6 largest volunteer computing projects.
