kandi X-RAY | falcon Summary

falcon is a Java library typically used in Logging, Prometheus applications. falcon has no bugs, it has no vulnerabilities, it has a Permissive License and it has high support. However falcon build file is not available. You can download it from GitHub.

Falcon is a tool aimed at easing the understanding of distributed system executions. Falcon ingests events logged by popular tracing tools (e.g. eBPF, strace, log4j) and merges them into a single causally-coherent execution trace. To further improve the reasoning about the runtime behavior of the system, Falcon also generates a space-time diagram depicting the events and their happens-before dependencies.

Splitting by comma, is the right way, you just need to store the the array returned from the split function into an ArrayList or an array of Strings array, like this:

QUESTION

"If-element" does not react when calling included template

Asked 2021-May-21 at 07:21

I am looking to build a simple logic to let user define which templates that should be called upon. The code illustrates a minimized example. The setup is very useful when having many templates, e.g. the output I am building is about 2.600 lines of XHTML code. Then it is very good being able to exclude several templates to focus on only some of the templates.

I have created above setup (previously) successfully having XML as source file and modularized code. I suspect it is my setup with having JSON as source file and the adaption of code that causes the problem.

Below code should allow the user to switch variable "build-with-books" from 0 to 1, and if set to 1, the "if" element should call the included template.

I am sure that there are many "smarter" way of solving my needs. Currently I am just looking to understand why my code does not follow the wanted logics of switching on/off the build of elements.

XSLT fiddle is down so I just paste my code below:

Working through duplicates along rows in DataFrame and deleting all except the last one in Python Pandas

Asked 2021-May-18 at 04:44

I am miserably stuck at Pandas Data Cleaning. I have made a very simple example to demonstrate my problem. For each row, I want to delete/alter the duplicate and keep the last one. Currently, my DataFrame is 'animals'. And I want it to be the DataFrame 'animals_clean'

Imagine this DataFrame. You can see duplicates along axis=0, e.g. 'cat' is repeated in row 0

Here are some of the options:

If you can use CloudFront in-front of S3 and use the CloudFront URL for the static content, do so. Here is more information.
You can also host the static content on any publicly accessible website e.g. on Github pages which is also a CDN for free.
You can use Data URLs in place of the images. You must convert the images to the Base64 encoded version and use them directly in the HTML.
You can use SVG as an image. You must convert your existing images to SVG and directly embed the contents in the HTML.
