When typhoon Maria hit Puerto Rico on September 20, 2017, I watched closely because the storm devastated my homeland and the status the status my fogeys nonetheless are living. They misplaced communication, and that i stand in intelligence wishing they had a manner to hold in touch. within the months that adopted, my coronary heart ached with each sage I heard of households who had been left without a option to compass every different physically because of broken infrastructure and no pass to attain every other very nearly due to lack of connectivity.
expertise played (and continues to play) a major role in the island's healing. but the confiscate technology, utilized on the confiscate second, could acquire made even more of a change. figuring out that the underlying technology exists to support individuals in natural disasters is a stout piece of what fueled us to launch demand Code. IBM partnered with David Clark cause, the United international locations Human Rights, the American purple move, and new enterprise buddies (NEA) to launch this global, multi-year initiative to developers to befriend limpid up pressing global complications. In 2018, they geared toward mitigating the consequences of herbal failures through sustainable utility options.
greater than 100,000 developers and records scientists from 156 international locations participated in their inaugural demand Code problem and submitted hundreds of magnificent options. It became inspiring to contemplate so many builders build in lots of of thousands of hours of coding outdoor of their day jobs — entire to support individuals they've on no account met.
talking with builders world wide, i noticed that I wasn't on my own as a technologist who has been for my portion littered with herbal disasters. in addition to Puerto Rico, they met developers on every continent who had encountered earthquakes, wildfires, flooding, and greater. The selection to lend their faculty to a more robust trigger become convenient.
We made phenomenal progress in 2018, however we're not stopping there. definitely, we're doubling right down to expand their network of companions and enhance the number of lives they will aid improve.Coding for a higher cause
The demand Code team recently back to San Juan, Puerto Rico, the status they joined 500 business, govt, and NGO leaders for the Clinton international Initiative motion community on submit-disaster recuperation. This two-day adventure focused on setting up new, selected, and measurable plans to ameliorate recuperation and promote long-time period resiliency throughout Puerto Rico, the us Virgin Islands, Dominica, Antigua, and Barbuda.
To that conclusion, we're announcing a new collaboration between IBM and the Clinton international Initiative university. We're teaming up to travail without laggard with school college students to support them harness the energy of expertise, akin to AI, blockchain, cloud, and IoT fueled by means of facts, to boost options for one of the crucial world's most pressing challenges, including natural disasters.Code, group, and faculties
This year, we're planning to host a progression of in-adult and online campus "codeathons" to interact and equip school students with the expertise and expertise resources they necessity to assist rotate their concepts into tangible motion.
we've considered already that college students are invaluable sources of notion for catastrophe relief options. Take, as an instance, Syracuse institution graduate pupil Anmol Handa and his classmates. As portion of a codeathon remaining year, he and his group developed a funding platform to assist small groups in rebuilding their communities following failures. another promising thought changed into introduced forth by Jonah Mudse of Rensselaer Polytechnic Institute, who labored on a student team that created an Airbnb-impressed home sharing app to befriend displaced families in need.From competitors to implementation
We're in the process of taking many of the confiscate concepts from ultimate yr's competition and putting them into action, starting with the 2018 call for Code profitable crew, venture Owl. This IoT and utility respond has the power to hold communities linked within the aftermath of a catastrophe. or not it's exactly the class of solution that could acquire stored me in palpate with my family unit following typhoon Maria in 2017.
As destiny would acquire it, Luis Arocho, Chief information Officer for the government of Puerto Rico, has agreed for his office to serve as an implementation companion with the intent of retaining first responders and victims related in a herbal disaster. They believe Puerto Rico is the flawless status to serve as a checking out environment as this technology is deployed, and the IBM company provider Corps is poised to travail with the OWL team to get it ensue.
At IBM, we're always considering of ways they can harness the energy of know-how for respectable. As technologists, they recognize we're more desirable once they travail together. this is why we're so excited to crawl into the next iteration of delivering code for first rate with new companions by using their facet. together, we're expanding the scope of the developers they will attain and the variety of lives they will assist improve. the realm can entire the time expend yet another hero. They hope you're going to dependence donning your cape and becoming a member of us in this impressive event.

SYDNEY, AUSTRALIA--(Marketwire - March 31, 2009) - EnergyAustralia, Australia's largest electricity distribution network, today announced an agreement with IBM (NYSE: IBM) for the implementation of an energy network monitoring and control solution.
A key project within EnergyAustralia's overall bright network program, the Distribution Monitoring and Control (DM&C) project involves the roll-out of 12,000 sensing devices throughout the electricity distribution network, creating a smart grid. The project will enable EnergyAustralia to deliver energy more efficiently and reliably, and allow a greater number and compass of environmental solutions to live integrated into the electricity network such as renewable energy.
Under the agreement signed in the first quarter of this year, IBM will design and build the system IT architecture to support the project, in which sensing devices will connect with EnergyAustralia's operational systems using a combination of fourth generation and existing technologies. This world-class bright network will carry the necessary data for EnergyAustralia to reduce outages through faster weakness location and preventative maintenance and, to travail towards managing distributed energy sources such as solar and storage devices.
EnergyAustralia's Managing Director George Maltabarow said the project was an faultfinding portion of the company's initial investment of $170 million in its smart network rollout.
"This project will befriend us wait at the forefront of the global bright network transformation," Mr. Maltabarow said. "It will give us an instant picture of the electricity network which will befriend abbreviate power interruptions by allowing us to quickly locate and repair faults.
"It will likewise weigh preventative maintenance can live better targeted so they can avoid faults and outages in the first place."
In addition to consulting, systems integration and IT services expertise, IBM has invested heavily in solutions such as Tivoli Netcool and Websphere Datapower to assist utilities in realizing their bright network visions.
"IBM is delighted to bring its infrastructure, systems integration and project management expertise to stand on this ground-breaking transformation project," said David Murray, generic Manager, IBM Communications Sector, Australia.
"Only through the creation of a smart grid that can sense, communicate, analyze and respond, can Australia build the energy infrastructure it needs to meet the challenges of climate change, globalization, and changing consumer demand."
IBM Smart Grid
IBM is working with clients in nearly 50 Smart Grid engagements across emerging and ripen markets around the world. More about IBM's 'Smarter Planet' initiative: its vision to bring a new plane of intelligence to how the world works -- how every person, business, organization, government, natural system, and man-made system interacts, can live institute here: http://www-03.ibm.com/press/us/en/presskit/26094.wss
EnergyAustralia bright Networks
EnergyAustralia began its bright network program in 2006. It was the first utility in the world to build and operate a communications network using carrier grade Internet Protocol (IP) technology. EnergyAustralia has likewise rolled out 800 kilometres of fibre optic cable to its 200 major substations and depots, installed hundreds of communications switches, and built a ordeal telecommunications network to allow two-way communication across its electricity network.

Performance engineering has a rather long and fascinating history, especially if considered in the context of changing computing paradigms. While not everything in the past may live applied to every new technology, the underlying principles often remain the same—and erudition of history keeps us from reinventing the wheel when it is unnecessary. Unfortunately, statements referring to the past are not often completely correct. The history of performance engineering is not well-known, so here is some information that I find to live quite interesting. The approach was to find the first ripen appearance of still-relevant performance concepts (without diving into the in-depth history of each notion). It is not scientific research, and not much information is available overall—so a lot of faultfinding information may still live missed.
We will start by listing the following computing paradigms:
Performance expertise related to a paradigm usually materializes later when the technology is more mature.Mainframes
Performance went beyond single-user profiling when mainframes started to support multiprogramming. In the early mainframe years, processing was concerned mainly with batch loads. Mainframes, however, had sophisticated scheduling and could ration consumed resources. They likewise had pretty powerful OS-level instrumentation allowing the engineers to track down performance issues. The cost of mainframe resources was high; therefore, capacity planners and performance analysts were needed to optimize mainframe usage.
While not everything in the past may live applied to every new technology, the underlying principles often remain the same—and erudition of history keeps us from reinventing the wheel when it is unnecessary.
We can definitely divulge that performance engineering became a distinct discipline when instrumentation was introduced with SMF (System Management Facilities), released as portion of OS/360 in 1966 (still in expend in IBM z/OS mainframes today).
In 1968, Robert Miller (IBM) in his Response Time in Man-Computer Conversational Transactions paper described several threshold levels of human attention. The paper was widely cited by many later researchers and remains mostly germane now.
In 1974, monitoring was introduced with RMF (Resource Measurement Facility) as portion of MVS (still in use). OMEGAMON for MVS by Candle (acquired by IBM in 2004), released in 1975, is often claimed to live the first real-time monitor.
A performance community, the Computer Measurement Group (CMG), was created in 1974, holding annual conferences ever since—now across a wide spectrum of technologies.
In 1977, BEST/1 was released by BGS Systems (acquired by BMC in 1998), the first commercial package for computer performance analysis and capacity planning to live based on analytic models.Distributed Systems
When the paradigm changed to client-server and distributed systems, the available operating systems at the time didn't acquire much instrumentation or workload management capabilities. Load testing and system-level monitoring became the primary ways to ply multi-user performance. Deploying across multiple machines was more difficult, and the cost of rollback was significant, especially for Commercial Off-The-Shelf (COTS) software that might live deployed by hundreds or even thousands of customers. Thus, there was more of a necessity for performance design to live correct from the beginning.
"Fix-it-later was a viable approach in the 1970s, but today, the original premises no longer hold - and fix-it-later is archaic and dangerous. The original premises were:
Performance problems are rare.
Hardware is hasty and inexpensive.
It's too expensive to build responsive software.
You can tune software later, if necessary."
Have you heard something enjoy this recently? That is a quote from Dr. Connie Smith's Performance Engineering of Software Systems, published in 1990. The reserve presented the foundations of software performance engineering, and already had 15 pages of bibliography on the subject.
The most known load testing tool, LoadRunner, was released in 1991 by Mercury Interactive (acquired by HP in 2006, now portion of Micro Focus). For a while, load testing became the main pass to ensure elevated performance of distributed systems, and performance testing groups became the centers of performance-related activities in many organizations.
"Fix-it-later was a viable approach in the 1970s, but today, the original premises no longer hold - and fix-it- later is archaic and dangerous."
The term Application Performance Management (APM) was coined by Programart Corp. (acquired by Compuware in 1999) in 1992 (in the mainframe context, as a combination of their STROBE and APMpower tools). However, STROBE, which they mention to as an application performance measurement tool, had been on the market since the '70s. Still, there is an persuasion that the first APM tool—as they know them now—was Introscope by Wily Technology, founded by Lew Cirne in 1998 (acquired by CA in 2006).
The history of End-User Monitoring (EUM)/Real-User Monitoring (RUM) can live traced at least to ETEWatch (End-to-End Watch), an application response time monitor released in 1998 by Candle (acquired by IBM in 2004, then a portion of Tivoli). However, EUM/RUM gained popularity later with development of web and mobile technologies.Web and Mobile
Most existing expertise was still applicable to the back-end. The first books to apply existing erudition and techniques to the web were published in 1998—for example, Web Performance Tuning and Capacity Planning for Web Performance.
In 2007, Steve Souders published elevated Performance Web Sites: Essential erudition for Front-End Engineers, stating that 80-90% of user response time is spent in the browser, which started a movement of Web Performance Optimization (WPO) centered on the client-side.
The WPO community was built around the Velocity Conference (first held in 2008) and Web Performance meetups. Velocity was a very accepted performance conference—at least until Steve Souders stepped off as an organizer, O'Reilly merged Web Performance into the Fluent conference, and Velocity became more of a DevOps conference. Maybe it was an indication that WPO had become more ripen and integrated with other aspects of technology.
Mobile technologies supported the further development of web performance, as client-side performance was even more faultfinding on mobile devices.Cloud
In the terminal ten years, they saw another paradigm shift to the cloud. While the term "cloud computing" was popularized when Amazon released its Elastic Compute Cloud in 2006, references to "cloud computing" acquire appeared as early as 1996. Technologies ripen more quickly nowadays—for example, Amazon's own monitoring solution CloudWatch was released only three years later, in 2009. Of course, many established performance products started to support cloud, and new products still enter the market.
While the cloud looks much different than mainframes, there are many similarities between them, especially from a performance point of view. They both provide:
Availability of computer resources to live allocated.
An simple pass to evaluate the cost associated with these resources and implement chargeback.
Isolation of systems inside a larger pool of resources.
Easier ways to deploy a system and drag it back if needed without impacting other systems.
However, there are notable differences that get managing performance in the cloud more challenging. First of all, there is no instrumentation on the OS level, and even resource monitoring becomes less trustworthy due to the virtualization layer. So, instrumentation must live on the application level. Second, systems are not completely isolated from the performance point of view, and they could repercussion each other, and they mostly acquire multi-user interactive workloads, which are difficult to foretell and manage. That means that such performance risk mitigation approaches enjoy APM, performance testing, and capacity management become very faultfinding in a cloud environment.What Lies Ahead?
While performance is the result of entire design and implementation details, the performance engineering zone remains very siloed—maybe due to historic reasons, maybe due to the huge scope of expertise. People and organizations trying to condense entire performance-related activities together are rather few and far apart. Attempts to span different silos (for example, DevOps) often leave many faultfinding performance engineering areas out.
Technologies ripen more quickly nowadays—for example, Amazon's own monitoring solution CloudWatch was released only three years later, in 2009.
The main lesson of the history is that the sentiment that they are near to solving performance problems has existed for the terminal 50+ years, and it will probably wait with us for a while—so instead of hoping for a silver bullet, it is better to understand different existing approaches to mitigating performance risks and find an optimal combination of them to address performance risks in your particular context.

R is a open source and very accepted programming language and environment for statistical computer and graphics.R was designed by statisticians and was specialized for statistical computing, and thus is known as the lingua franca of statistics. It is mostly used in Data Science and Machine Learning. It is managed by R core development team — team of volunteer developer from across the globe. R provide a wide variety of statistical and graphical techniques and highly extensible.It was developed at Bell Laboratories by John Chambers and colleagues.R is a consolidated environment for performing statistical operation and generating R data analysis reports in graphical or text formats.History of R:
R was created by Ross Ihaka and Robert Gentleman at the University of Auckland, new Zealand, and currently developed by the R development Core Team. R is an implementation of the S programming Language and combines with lexical scoping semantics inspired by Scheme. John Chambers and colleagues developed S at Bell Laboratories. R was named partly after the first names of two R authors. The initial version of R is released in 1995 and a stable beta version released in 2000.Language Features:
R is not only language in the domain of statistical computing and graphics. Some accepted alternatives of R:
Python is very powerful elevated level , kick oriented language with very simple syntax.It is likewise extremely accepted between data scientist and researcher. Most packages in R is equivalent to packages in Python.
The selection between R vs Python likewise depends on what you are trying to accomplish with your code. If you are trying to analyze a data set and present the findings in a research paper, then R is probably a better choice. But if you are writing a data analysis program that runs in a distributed system and interacts with lots of other components, it would live preferable to travail with Python.
SAS (Statistical Analysis System)
SAS (Statistical Analysis System) introduced the SAS business Intelligence & Analytics Solution for big enterprises to explore their big data sets in a visually appealing format. SAS analytics is a data analytics instrument that is used increasingly in Data Science, Machine learning, and business Intelligence applications.It has been the first selection of many private enterprise for their analytics for a long time.
Although SAS is extremely accepted in commercial analysis, R and Python is gaining momentum in the enterprise space and companies are likewise trying to crawl towards open-source technologies.
SPSS — Software package for statistical analysis
SPSS is a accepted statistical instrument which is commonly used in the gregarious sciences and is considered as easiest to learn among enterprise statistical software/tools.It is loved by non-statisticians because it is similar to excel. SPSS has the very downside as SAS — it is expensive. SPSS was acquired by IBM in 2009 for a reported $1.2 billion.Why should they adopt R Programming Language ?
R provides the liberty of selecting and editing tools to interact with the aboriginal console. While scripting in R, you don’t necessity to type commands but rather call functions to achieve results. The R Console allows command editing.The Prominent editors available for R programming language:
R holds a reputation for getting things done with very limited code.Let us start scripting in R with a very simple program called “Hello World”.#printing Hello Worldprint("Hello World !!")
And the output is
Let create a more involved script in R to generate 1000 number in a random distribution and marshal them based on their frequency and create a bar chart.n <- floor(rnorm(10000, 500, 100)) t <- table(n) barplot(t)
And the output of this script :A Bar Plot
NOTE: The extension of R scripts is .R .Conclusion:
In a nutshell, R is simple to learn and expend language. It is widely in exercise and students and data scientists. With the data science predicted to grow immensely the importance of R is likewise undoubted. Hence learning R will the wisest determination you will get for launching your career in the stout data space.
