SiriusCon 2017 - Get your stakeholders into modeling using graphical editorsObeo
The presentation introduces a number of these pilot projects, where we have developed design tools comprising of Sirius based graphic editors and Domain Specifics Languages (DSLs). These tools allow formal specification of requirements, automatic analysis of system performance, and code generation. The models are designed using Sirius and are persisted textually using Xtext. We have found that the use of graphical editors in these projects greatly helped communicating designs between stakeholders and also leveraged the general acceptance of the MDE approach. In our case, Sirius models can become quite big and require a proper layout. We used Eclipse Layout Kernel (ELK) for automatic layout which turned to be essential for efficiency. The presentation concludes with future directions towards utilizing Sirius in fulfilling new requirements from stakeholders, e.g., generating documentation from models.
This document provides an overview of a roundtable discussion on real-time analytics with Hadoop. It discusses the requirements for real-time data, applications, and queries.

For queries, analysts need to query data as soon as it lands without waiting. It also discusses how MapR addresses these requirements through features like NFS access, low-latency database access, and table replication. The presentation concludes with a discussion of ensuring security, reliability, and other enterprise capabilities for real-time analytics.

The document summarizes research done at the Barcelona Supercomputing Center on evaluating Hadoop platforms as a service (PaaS) compared to infrastructure as a service (IaaS). Key findings include:
- Provider (Azure HDInsight, Rackspace CBD, etc.) did not significantly impact performance of wordcount and terasort benchmarks.
- Data size and number of datanodes were more important factors, with diminishing returns on performance from adding more nodes.
- PaaS can save on maintenance costs compared to IaaS but may be more expensive depending on workload and VM size needed. Tuning may still be required with PaaS.

Risk management is the process of identifying, evaluating, and controlling threats to an organization. Information technologies have highly influenced risk management by providing tools like risk visualization programs, social media analysis, data integration and analytics, data mining, cloud computing, the internet of things, digital image processing, and artificial intelligence. While information technologies offer benefits to risk management, they also present new risks around technology use, privacy, and costs that must be managed.
Inertial sensors measure and report a body's specific force, angular rate, and sometimes the magnetic field surrounding the body using a combination of accelerometers, gyroscopes, and sometimes magnetometers. Accelerometers measure the rate of change of velocity. Gyroscopes measure orientation and angular velocity. Magnetometers detect the magnetic field around the body and find north direction. Inertial sensors are used in inertial navigation systems for military and aircraft and in applications like smartphones for screen orientation and games. They face challenges from accumulated error over time and limitations of MEMS components.
The document discusses big data integration techniques. It defines big data integration as combining heterogeneous data sources into a unified form.

The document discusses security challenges with internet of things (IOT) networks. It defines IOT as the networking of everyday objects through the internet to send and receive data. Key IOT security issues include uncontrolled environments, mobility, and constrained resources. The document outlines various IOT security solutions such as centralized, protocol-based, delegation-based, and hardware-based approaches to provide confidentiality, integrity, and availability against attacks.
The Security Aware Routing (SAR) protocol is an on-demand routing protocol that allows nodes to specify a minimum required trust level for other nodes participating in route discovery. Only nodes that meet this minimum level can help find routes, preventing involvement by untrusted nodes. SAR aims to prevent various attacks by allowing security properties like authentication, integrity and confidentiality to be implemented during route discovery, though it may increase delay times and header sizes.
The Bhopal gas tragedy was one of the worst industrial disasters in history. In 1984, a leak of methyl isocynate gas from a pesticide plant in Bhopal, India killed thousands and injured hundreds of thousands more. Contributing factors included the plant's lax safety systems and emergency procedures, its proximity to dense residential areas, and failures to address previous issues at the plant. In the aftermath, Union Carbide provided some aid but over 20,000 ultimately died and many suffered permanent injuries or birth defects from the contamination.

Enhancing the performance of kmeans algorithmHadi Fadlallah
The document discusses enhancing the K-Means clustering algorithm performance by converting it to a concurrent version using multi-threading. It identifies that steps 2 and 3 of the basic K-Means algorithm contain independent sub-tasks that can be executed in parallel. The implementation in C# uses the Parallel class to parallelize the processing. Analysis shows the concurrent version runs 70-87% faster with increasing performance gains at higher numbers of clusters and data points. Future work could parallelize the full K-Means algorithm.

The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.
Global Situational Awareness of A.I. and where its headedvikram sood
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.

ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data LakeWalaa Eldin Moustafa
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

Radiation pollution is a critical concern due to high damage that it may cause to humans and environment.
To minimize damages, controlling and monitoring is very important.
In the past century, it was hard to have centralized radiation monitoring system due to the limitations of traditional networks.
With the rise of internet of things, radiation measurement unit was integrated in wireless sensors, and used to transmit data via communication networks.
As result, new challenges appeared:
1- when sensors collect data in real-time it may result a massive amount of data, which is transferred in a high speed.
2- the utilization of different types of sensors implies that we have different data formats.
The traditional data technologies cannot handles any more this type of data. Also existing solutions are conventional and mostly handles data in batch style.
In this experimental research, our objective is to build a scalable radiation data engineering platform that has:
the ability to process and monitors huge amount of radiation data with high speed having different formats in real-time.
Our proposed system is called RaDEn an abbreviation of radiation data engineering system
It guarantees high scalability and fault-tolerance, handles big data And has the ability to monitor data in real-time and batch-style
The system architecture is composed of 6 layers:
The data sources which consists of radiation sensors installed in different places, Flat files and Archive relational databases
The data ingestion layer, which is responsible of collecting data and send it to the data processing engine and data storage layer
The data storage layer which allows storing huge volume of data, and allow end-user to search among the stored data
The data processing engine it allows processing radiation data in real-time and raise alerts when high radiation level is detected
The visualization layer, it allows showing real-time graphs
The coordination layer: it guarantee the communication between the different technologies used in different layers. This task is done by Apache zookeeper which is required by data technologies.
Next, we will describe the technologies that we have used in each layer
First, the data ingestion layer.
To read data with different formats from sensors and flat files we have used Apache Kafka, which is a distributed, scalable and fault-tolerant technology
We have create two Kafka topics: one fro real-time processing and one for batch style.
Data are sent from the data sources to Kafka producers then are sent distributed into kafka pipelines in parallel then until they are consumed.
Data are sent to the data storage layer via Apache flume agent (one for each kafka topic) and at the same time it is sent to the processing engine.
Also the system is able to import archival data from relational databases using apache sqoop import where we only have to specify the connection string of the relational database and the location into the hdfs
The data storage layer has 2 components:
The data repository: which consists of Hadoop distributed file system, which allow parallel computing and guarantee high scalability and fault-tolerance: the data comes from the ingestion layer to the Hadoop master node and then it is replicated over the slave nodes in a text file format.
The metadata: which relies mainly on Apache Hive. it allows creating Tables on the top of HDFS directories, and let the user able to retrieve data from the repository using SQL-Like languages (Spark-SQL, HiveQL)
The Data processing layer relies mainly on Apache Spark , which is a scalable, fault-tolerant, distributed data processing technology. The Apache spark master receive the data from the data ingestion layer and send the data to the spark workers to be processed then visualized in the data visualization layer.
Beside of Spark, we have used pandas python library which contains many function to manipulate data.
The data visualization layer relies mainly on a python library called Matplotlib, it a very simple library that allows user the draw real-time graphs.
TO implement this system, we have configured three (linux-based) virtual machines, one machine acts as hadoop master node, and it contains apache kafka, flume, hive, sqoop and spark installations.
Other machine act as Hadoop data nodes.
We have used only one Kafka node and one Spark node due to the small dataset that we have received, but we can add more nodes when required
We have written a python script that implement the following alarm system (based on the LAEC requirements)
The alarm system work as the following:
….
We run the experiments with a dataset proceed by the LAEC.
For confidentiality purposes we they give us the data in form of flat files instead of giving access to the sensors or the web server.
The data is collected from one sensor located in Beirut 1 august two thousand fifty till 1 august two thousands sixty
The dataset contains information such as ….
First, we have to run the required services (Hadoop cluster, spark, kafka, flume agent and python script)
To simulate reading data from sensor we have created a directory and a listener on the top of it: when any file is added to the folder, it will start sending it line by line to the kafka broker.
Each row is processed and visualized using the python script.
The following figure shows some sequential screenshots of the real-time graph, we can se the evolution of the radiation level in function of date and time
When there is an alert, it is raised in form of a message box like shown in the figure, the alarm level is written in the title and the description in the body
On the top of the HDFS directory we have created a Hive external table, and we created a view that read from this table to ignore messy data rows and convert data types.
Then we can retrieve data using SQL-Like languages such as spark-SQL and HiveQL.
The figure show a screenshots of the results of the previous query.
As a conclusion, we can say that we have designed and implemented a radiation data engineering system that:
- can handles massive amount of data in real-time and at rest.
- relies on scalable, fault-tolerant and distributed technologies such as Hadoop.
- Allow users to retrieve stored data using SQL-Like languages
Also, we have implemented an alarm system to monitor the radiation data and raise alert when high radiation level is detected.
This research has some limitations due to the following reasons:
It is not evaluated using big data due to the small dataset that we have received
We didn’t get access to the sensors or web server
Lack of big data technologies documentation
The time limit constraint
In the future, there are many improvements that can be made:
Improving the visualization layer, using more powerful tools such as bokeh python library and Kibana which is a part of elastic search framework
Design and implement user friendly interfaces
Creating a data warehousing job that run every day and convert the newely stored files into ORC format which guarantee higher performance
We can use distributed search engines such as Solr and ElasticSearch
