We are using dapr along with an input binding to consume IoT Events from Azure Event Hub. The event hub has 32 partitions and the sender uses the device id as partition key. The controller receiving the events delegates them to dapr Actors for processing.

Now my expectation would be, that the messages in each partition are processed in parallel, resulting in parallel requests to the controller receiving the events allowing for up to 32 concurrent event batches to be processed.

However tests show that the events are received synchronously. The consequent event is received just after the full processing of the previous event has completed.

Now i know that actors process messages one after the other by design but i did not read anything like this for input bindings according to the documentation.

Is there anything i'm completely missing? Otherwise i could not image how this system could scale.

We are using dapr 0.11 along with ASP.NET Core 3.1 running in an AKS cluster.

I've taken the Dapr pub/sub How-to sample and tried to update it to use RabbitMQ

I've downloaded the Docker rabbitmq:3 image from DockerHub and it should be listening on amqp://localhost:5672.

I have created a new component file for RabbitMQ called rabbitmq.yaml and placed it in the .dapr/components directory. My component configuration for RabbitMQ is:

The case is that at the beginning of Page, Elements should be drawn in one column, and after that, elements in the same page should be drawn in two columns.

So far, according to the iText example "c02e10_jekyllhydev6", I just can switch different renderers between pages, which means first applying DocumentRenderer, then add AreaBreak of Next Page, and applying ColumnDocumentRenderer in the new page.

The code:

I'm trying to build some dll to wrap some Computer Vision methods in a c++ software to use them a c# software, and I need to call some tbb (Threading Building Blocks) methods from the c++ methods to process some frame. I'm developing in CLR using Charset Unicode, in visual studio, and once I call the tbb header

I am a newbie in the Hadoop world and I am trying to learn basics from this tutorial. I have freshly installed Hadoop 2.9.2 on my machine in a pseudo-distributed way and did the following setup.

core-site.xml

code below is long but really straight forward only require code to put forward ability to slide from first slide to last slide to that return to first slide to traverse.

I’m looking to understand how to properly structure my .gitlab-ci.yml and Dockerfile such that I can build a C++ application into a Docker container.

I’m struggling with where the actual compilation and link of the C++ application should take place within the CI workflow.

What I’ve done:

• My current in approach is to use Docker in Docker with a private gitlab docker registry.
• My gitlab-ci.yml uses a dind docker image service I created based on the the docker:19.03.1-dind image but includes my certificates to talk securely to my private gitlab docker registry.
• I also have a custom base image referenced by my gitlab-ci.yml based on docker:19.03.1 that includes what I need for building, eg cmake, build-base mariadb-dev, etc.
• Have my build script added to the gitlab-ci.yml to build the application, cmake … && cmake --build . The dockerfile then copies the final binary produced in my build step.

Having done all of this it doesn’t feel quite right to me and I’m wondering if I’m missing the intent. I’ve tried to find a C++ example online to follow as example but have been unsuccessful.

What I’m not fully understanding is the role of each player in the docker-in-docker setup: docker image, dind image, and finally the container I’m producing…

What I’d like to know…

• Who should perform the build and contain the build environment, the base image specified in my .gitlab-ci.yml or my Dockerfile?
• If I build with the dockerfile, how to i get the contents of the source into the docker container? Do I copy the /builds dir? Should I mount it?
• Where to divide who performs work, gitlab-ci.yml or Docker file?
• Reference to a working example of a C++ docker application built with Docker-in-Docker Gitlab CI.

.gitlab-ci.yml

Me and my team currently work on the read side of a CQRS and event-sourcing system. We want our projectors to be able to listen to only a subset of all events and we want our projectors to be idempotent since an event can be published many times. Here is our current architecture:

Since a projectionist doesn't handle all events how it can know if an event hasn't been received in the correct order or if an event has already been received? We can't use the sequence number because the sequence number is related to a stream and not an event type.

The terms "projectionist", "projection ledger" and "projector" comes from this article.

I'm using ZURB Foundation 6.4 (ZURB template) for my Website. I wanted to test out my newly implemented backend and tried to gather some input and send it to my php backend via jquery AJAX.

Meanwhile, I've managed to do so, but I encountered a very strange problem. I've used the following building block: https://foundation.zurb.com/building-blocks/blocks/floated-label-wrapper.html

I modified it a little, but just concerning the id's and placeholders and such stuff, nothing functional. In the end, I had this markup used as a partial for one of the views I've generated:
