Creating PDFs in APEX after ORDS 19.1

Creating PDFs in APEX after ORDS 19.1

Until 19.1 ORDS provided a built-in printing engine based on Apache FOP which allowed you to download a PDF version of your reports and XLS-FO templates in a very easy manner. However in ORDS 18.4.0 release notes we could find information that this feature is deprecated and will be removed in future release. This is exactly what happened with the release of ORDS 19.2.

So what actually happened? 

This is from Oracle’s release notes of ORDS 19.2:

Distributed Deep Learning for Physics with TensorFlow and Kubernetes

Posted by Luca Canali on Monday, 23 March 2020

Summary: This post details a solution for distributed deep learning training for a High Energy Physics use case, deployed using cloud resources and Kubernetes. You will find the results for training using CPU and GPU nodes. This post also describes an experimental tool that we developed, TF-Spawner, and how we used it to run distributed TensorFlow on a Kubernetes cluster.

 

Benefits of a multi-layer system

Posted by Viktor Kozlovszky on Thursday, 19 December 2019

Designing a multi-layer system is not rocket science, the difficulty can lie in selecting the right technologies. The main concept behind the design is to have better control and fine tuning of the components . This blog post will discuss the benefits & limitations of implementing this type of design and our practical experience gained from using it for the Open Days reservation system, which helped to welcome 75.000 people on our site and was hosted on the Oracle cloud using their cloud services.

Internationalization of the 2019 Open Days reservation system

Posted by Viktor Kozlovszky on Tuesday, 12 November 2019

International organisations can have multiple official languages, in these casesusually their workflows/processes are designed to support that. CERN is one of those organisations, it's official languages are French and English. Therefore one of our tasks was to make the Open Days reservation system bilingual. In this article you will read about the choices we made to internationalize the system, what obstacles we faced and what solution we went for.

Open Days reservation system's high level overview - 2019

Posted by Viktor Kozlovszky on Tuesday, 29 October 2019

The LHC has a schedule of maintenance and performance upgrades. During these longer shutdowns CERN holds its major Open Days events. These allow the general public to visit areas normally restricted and used for research activity. Previous events have seen daily over 35k people visiting. To hold a big impact event successfully, certain preparations and arrangements are necessary. Our team’s responsibility was to deliver a reliable and highly available reservation system. This article gives a high level overview about the work that has been done and links together technical articles written about the Open Days reservation application.

Internationalization: concepts and implementations

Posted by Viktor Kozlovszky on Wednesday, 23 October 2019

We are in an era where lots of things can be achieved with just a few clicks and quick typing on the web. This simple and fast information exchange has made this method become a standard form of communication. The web removes physical boundaries and allows people with different nationalities and mother tongues to interact. Therefore it has become very important that all parties understand the information flowing through this channel. To provide the same experience for speakers of all other languages it has become essential to design websites with internationalization (later as "i18n"). The goal for this post is to give a better understanding about i18n and about the concepts behind the different framework implementations.
