Breaking Spark: Top 5 mistakes to avoid when using Apache Spark in productionNeelesh Srinivas Salian
Spark has been growing in deployments for the past year. The increasing amount of data being analyzed and processed through the framework is massive and continues to push the boundaries of the engine. Drawing on experiences across 150+ production deployments, Neelesh Srinivas Salian explores common issues observed in a cluster environment setup with Apache Spark and offers guidelines to help setup a real-world environment when planning an Apache Spark deployment in a cluster. Attendees can use these observations to improve the usability and supportability of Apache Spark and avoid such issues in their projects.
Topics include:
Scaling the architecture
Memory configurations
End-user code
Incompatible dependencies
Administration- and operation-related issues
May 2013 HUG: Apache Sqoop 2 - A next generation of data transfer toolsYahoo Developer Network
Apache Sqoop 2 is the next generation of the massively successful open source tool designed to transfer data between traditional SQL databases and warehouses into Apache Hadoop. Sqoop 2 is designed as a client-server system with a repository which stores connection and job information. Sqoop 2 is designed to support secure job submission and multiple different roles for users. In this talk, we will discuss the issues users faced in Sqoop 1, and the design of Sqoop 2 and how the issues faced in Sqoop 1 are being handled in Sqoop 2.

We looked at the data. Here’s a breakdown of some key statistics about the nation’s incoming presidents’ addresses, how long they spoke, how well, and more.

Study: The Future of VR, AR and Self-Driving CarsLinkedIn
We asked LinkedIn members worldwide about their levels of interest in the latest wave of technology: whether they’re using wearables, and whether they intend to buy self-driving cars and VR headsets as they become available. We asked them too about their attitudes to technology and to the growing role of Artificial Intelligence (AI) in the devices that they use. The answers were fascinating – and in many cases, surprising.
This SlideShare explores the full results of this study, including detailed market-by-market breakdowns of intention levels for each technology – and how attitudes change with age, location and seniority level. If you’re marketing a tech brand – or planning to use VR and wearables to reach a professional audience – then these are insights you won’t want to miss.
UX, ethnography and possibilities: for Libraries, Museums and ArchivesNed Potter
These slides are adapted from a talk I gave at the Welsh Government's Marketing Awards for the LAM sector, in 2017.
It offers a primer on UX - User Experience - and how ethnography and design might be used in the library, archive and museum worlds to better understand our users. All good marketing starts with audience insight.
The presentation covers the following:
1) An introduction to UX
2) Ethnography, with definitions and examples of 7 ethnographic techniques
3) User-centred design and Design Thinking
4) Examples of UX-led changes made at institutions in the UK and Scandinavia
5) Next Steps - if you'd like to try out UX at your own organisation
The technologies and people we are designing experiences for are constantly changing, in most cases they are changing at a rate that is difficult keep up with. When we think about how our teams are structured and the design processes we use in light of this challenge, a new design problem (or problem space) emerges, one that requires us to focus inward. How do we structure our teams and processes to be resilient? What would happen if we looked at our teams and design process as IA’s, Designers, Researchers? What strategies would we put in place to help them be successful? This talk will look at challenges we face leading, supporting, or simply being a part of design teams creating experiences for user groups with changing technological needs.

Apachecon Europe 2012: Operating HBase - Things you need to knowChristian Gügi
If you’re running HBase in production, you have to be aware of many things. In this talk we will share our experience in running and operating an HBase production cluster for a customer. To avoid common pitfalls, we’ll discuss problems and challenges we’ve faced as well as practical solutions (real-world techniques) for repair.
Even though HBase provides internal tools for diagnosing issues and for repair, running a healthy cluster can still be challenging for an administrator. We'll cover some background on these tools as well as on HBase internals such as compaction, region splits and their distribution.
We'll also introduce our tool to visualize region sizing and distribution in the cluster, that we recently open sourced.
