These are my slides for the 5 minute overview talk I gave during a recent workshop at the European Commission in Brussels, on the topic of "Big Data Skills in Europe".
An overview of the development of the Apache Hadoop software stack, including some of the barriers to participation -and how and why to overcome them. It closes with some open discussion points/ideas of how the existing process can be improved.
From Batch to Realtime with Hadoop - Berlin Buzzwords - June 2012larsgeorge
In the early days of web applications, sites were designed to serve users and gather information along the way. With the proliferation of data sources and growing user bases, the amount of data generated required new ways for storage and processing. Hadoop's HDFS and its batch oriented MapReduce opened new possibilities, yet it falls short of instant delivery of aggregate data to end users. Adding HBase and other layers, such as stream processing using Twitter's Storm, can overcome this delay and bridge the gap to realtime aggregation and reporting. This presentation takes the audience from the beginning of web application design to the current architecture, which combines multiple technologies to be able to process vast amounts of data, while still being able to react timely and report near realtime statistics.

HBase Applications - Atlanta HUG - May 2014larsgeorge
HBase is good a various workloads, ranging from sequential range scans to purely random access. These access patterns can be translated into application types, usually falling into two major groups: entities and events. This presentation discussed the underlying implications and how to approach those use-cases. Examples taken from Facebook show how this has been tackled in real life.
HBase Advanced Schema Design - Berlin Buzzwords - June 2012larsgeorge
While running a simple key/value based solution on HBase usually requires an equally simple schema, it is less trivial to operate a different application that has to insert thousands of records per second. This talk will address the architectural challenges when designing for either read or write performance imposed by HBase. It will include examples of real world use-cases and how they

Social Networks and the Richness of Datalarsgeorge
Social networks by their nature deal with large amounts of user-generated data that must be processed and presented in a time sensitive manner. Much more write intensive than previous generations of websites, social networks have been on the leading edge of non-relational persistence technology adoption. This talk presents how Germany's leading social networks Schuelervz, Studivz and Meinvz are incorporating Redis and Project Voldemort into their platform to run features like activity streams.
How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
