We live in connected world -- till the internet connections can be flakey and non-existent. That should not disturb the user experience. "No internet connection" is a network problem and not the application problem.
With Bahmni (http://www.bahmni.org/) an easy to use open source hospital system, when thousands of community health workers were taking the patient data in physical papers (where the internet is not available), we are building offline capabilities for Bahmni. The tablets that the community health workers use are of very low hardware capabilities and we had to take most of the design decisions to enable offline capabilities with these limitations.
The talk is about the importance of "offline first applications", the technologies that enable that to happen, and our design, solution, and methodology -- to enable offline capabilities for Bahmni with the hardware limitations.
A semantic web is a relativity modern technology coined by Sir Tim Berners-Lee in 2001. Web 2.0 is readable by humans. We have HTML 5 and CSS and it does a great job of allowing information to be read by humans. Where web 2.0 fails is supporting machine reading. This then brings up web 3.0. Being able to support data is great, but often what we are most interested in is not the data itself, but the relationships between and among data. Think about how hard it is currently to get all water features. Those features are often in different services and provided by different organizations. I want to quickly and easily get all water features nationally. This is where a semantic web would be very useful because one can store the relationships between data to give you all water features. This talk will show you some of the advantages of a semantic web and how it can be used to answer questions that one would struggle to answer without it.
Hitchhiker's guide to the semantic web
What? There is more to the web than what we know? But why? What is semantic web? Why do we need it? How does it look like? How do we use it? Where is this applicable? What does linked data got to do with it? Is this the future of web?
2016: A good year to invest in Spanish property?Simon Birch
Since the economic downturn of 2008, property prices in Spain have fallen around 30%.2016 looks set to be the year that the Spanish property market finally ‘bottoms’ out and sees a 2% rise according to the rating agency Standard and Poors. Central to this recovery, will be Spain's continuing robust economic recovery into 2017, which is seeing steady improvements in the countries desperate unemployment levels and rising middle-class household income.

GIDS 2016 Understanding and Building No SQLstechmaddy
Storage becomes the key part of any Big Data system. There are few non-functional parameters that are expected from the Big Data storage systems like reliability, horizontal scalability, high availability, fault tolerance, etc. To support these properties and the change of data storage and access patterns in Big Data systems lead to a class of storage - NoSQLs. If there’s one rule in design -- there will always be trade-offs. CAP theorem defines the choices that we can make with the trade-offs. And ACID rules change to BASE in NoSQLs.
This talk focuses on understanding NoSQLs, the design decisions for designing NoSQL databases, an complete design example of key-value database, and patterns of replication and sharding.

If like many Brits, you’re planning on spending your retirement years (or at least a portion of those years) outside the UK, then you’ll no doubt have a few questions on how this will affect your state pension. With UK State Pension rules set to change in April 2016, there are a number of factors to consider when transferring funds overseas. At Currency Solutions, we help thousands of individuals transfer their State Pensions abroad, so we thought we’d put together a list of some of the most frequently asked questions our customers have.....
Technology -- the first strategy to startupstechmaddy
As the title suggests, the topic starts with how Strategy is very important differentiator for startups. Followed by a set of examples. The remaining part of the talk involves how many successful startups used Technology as the prime strategy, which made all the difference for them. It also talks on how Technology is not the only Strategy.
In April 2015, Apache Geode (incubating) was born from Pivotal’s GemFire, the distributed in-memory database. However, the donation of over 1M LOC was just the beginning of the journey. In this talk we discuss how the GemFire engineering team has adapted their development infrastructure, processes, and culture to embrace the “Apache Way". We present lessons learned and best practices for new and incubating open source projects in areas of initial code submission, IP clearance, governance policies, code review, and community building. We discuss the challenges the team faced and how we changed internal communication and software design processes to a community-driven model. In particular, we highlight effective strategies for growing a project community and embracing new members. Finally, we show how changing to the open source model has increased both productivity and quality.
This is a talk given by Jason Hoffman at a workshop given by Joyent called "Scale With Rails" in 2006. There's quite a bit of prescience in this presentation, including the first documented use of ZFS in production ("Fsck you if you think ZFS isn't production") and of OS-based virtualization (zones) in the cloud (which, it must be said, was not called "cloud" in 2006).

The deep web is the world wide web content, but that is not the part of the surface web. Which is indexed by standard search engines. Which can’t be accessed by the conventional search engines. 400 to 500 time more public information are included in the deep web than the surface web. The total quantity of the deep web is 1000 to 2000 time greater than the surface web.
BDI- The Beginning (Big data training in Coimbatore)Ashok Rangaswamy
The main objective of “Big Data intelligence” is to understand all of us better to predict the future. Be it 4 billion google queries a day or 1 billion FB users, we need smarter AI algorithms to learn and connect the dots from the ocean of data. With massive parallelism and Map-Reduce techniques, millions of servers take us one step closer to the “Turing’s Intelligent machine”. Near AI success stories are google, facebook, twitter, youtube and Amazon. Let's begin our journey by knowing big hype, big dreams of 50's , big laws, big growth and basic operations to extract big data intelligence.For more information on Big Data training in coimbatore, please visit https://bigzettab.wordpress.com/ . - Prof. Ashok.R, +91-9943900101, ashok@zettab.com.

The Impact of Cloud, Mobile, and Managing the Changing Platforms of Digital Collections presented by Carl Grant, Associate Dean, Knowledge Services & Chief Technology Officer, University of Oklahoma Libraries for the October 16, 2013 NISO Virtual Conference: Revolution or Evolution: The Organizational Impact of Electronic Content.
Ranganathan Balashanmugam talks about how one distributed organization (with bases in India and Australia) has applied distributed systems patterns to scaling distributed teams' processes and further improved them. He shares examples of what went right, what went wrong, what they've learned as they've built a network of effective distributed teams across multiple countries, in multiple timezones.
Apache parquet - Apache big data North America 2017techmaddy
Apache Parquet brings the advantages of compressed, efficient columnar data representation available to any project in the Hadoop ecosystem. Apache Parquet is built from the ground up with complex nested data structures in mind, and uses the record shredding and assembly algorithm described in the Dremel paper. We believe this approach is superior to simple flattening of nested name spaces. Apache Parquet is built to support very efficient compression and encoding schemes. Multiple projects have demonstrated the performance impact of applying the right compression and encoding scheme to the data. Apache Parquet allows compression schemes to be specified on a per-column level and is future-proofed to allow adding more encodings as they are invented and implemented. This talk highlights the internal implementation of Apache Parquet.
Big data event streaming is very common part of any big data Architecture. Of the available open source big data streaming technologies Apache Kafka stands out because of it realtime, distributed, and reliable characteristics. This is possible because of the Kafka Architecture. This talk highlights those features.
Apache big data 2016 - Speaking the language of Big Datatechmaddy
With the advent of feature based teams, software architecture styles like Microservices and deployment patterns like Devops are taking over. Each team takes autonomous decisions on technologies used, but there is always a need to define a common language for the services to communicate with each other. This way there will be a common wire format and avoid lot of mappers across the application. The other common scenario is in big data projects where the cluster of nodes need to communicate efficiently and effectively, with ease of API.
This talk highlights on Apache Avro and Apache Thrift which are used in Big data solutions -- which act as common language across different services/nodes in big data applications. These technologies act as language and platform neutral way of serializing structured data. This talk also shows examples and demos -- highlighting the pain points they solve.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.
