In the Hadoop world, writing Map Reduce is always a painful task especially when you want to create complex workflows with multiple Map Reduce jobs and having complex dependencies between them. There are high level languages like Pig latin or Hive which make writing Map Reduce jobs easy. But if you want to write complex logic, you need to write custom functions in Java, which makes testing and debugging difficult. This is where Cascading makes a developer's life easy. Everything is written in Java with ease of writing Map Reduce in high level language, similar to Pig or Hive. Once the logic is written, it can be easily be tested by running in stand-alone mode since everything is in Java. Not only that, Cascading provides Hadoop (or any other framework) independent APIs, which means workflows written in Cascading can be executed on multiple frameworks without any code change as long as Cascading connector is available

Large Environments rely on TroubleTicket tool and HelpDesk for managing IT issues. Bridging Zabbix with over 5000 servers and HelpDesk manually is a painful and impossible project. In this presentation we will cover how we may integrate Zabbix with HelpDesk, the architecture and what are the issues specially in Large Environments. As an example, we will cover the case study of Zabbix - ServiceNow integration, as it was developped for SwissLife and released as OpenSource.

Queues are a great addition to any application that has some tasks that need processing asynchronously. This could be sending a confirmation email, resizing an avatar, or recalculating a running total of some kind; in all those cases it would be cool to send the response back to the user and then sort out that task later. This session looks at how to use a RabbitMQ job queue in your application. It also looks at how to design elegant and robust long-running workers that will consume the jobs from the queue and process them. This session is ideal for technical leads, developers and architects alike.

Dubai, often portrayed as a shimmering oasis in the desert, faces its own set of challenges, including the occasional threat of flooding. Despite its reputation for opulence and modernity, the emirate is not immune to the forces of nature. In recent years, Dubai has experienced sporadic but significant floods, testing the resilience of its infrastructure and communities. Among the critical lifelines in this bustling metropolis is the Dubai International Airport, a bustling hub that connects the city to the world. This article explores the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.
