QUESTION
I am trying to generate a table to record articles published each month. However, the months I work with different clients vary based on the campaign length. For example, Client A is on a six month contract from March to September. Client B is on a 12 month contract starting from February.
Rather than creating a bespoke list of the relevant months each time, I want to automatically generate the list based on campaign start and finish.
Here's a screenshot to illustrate how this might look:
Below is an example of expected output from the above, what I would like to achieve:
Currently, the only month that's generated is the last one. And it goes into A6 (I would have hoped A5, but I feel like I'm trying to speak a language using Google Translate, so...).
Here's the code I'm using:

QUESTION
Most of my WordPress websites have a background image in the top fold. These images are the Largest Contentful Paint Element on the page and usually they get loaded last. Somewhere I read that 'Background images are last in line to be grabbed when a page is loaded'. Is it true?
Is it a good idea to use a place holder or image in the place of the background image and then change it later so that the LCP gets loaded quickly like below.
ANSWER
Answered 2021-May-14 at 01:42You don't want to use a placeholder image to prioritize your background images in situations like this, you want to use . That will tell the browser to start downloading the image as soon as possible.
Try adding the following code to the of your page, and then use your background image as normal. It should load much faster:

QUESTION
I have written an impex in trainingcore/resources/trainingcore/import/common/my_products.impex
After that, I did a system update and checked the trainingcore extension for project data creation. But the impexes were not loaded. After reading some articles, I realised it has something to do with CoreSystemSetup.java class, but I can't get exactly what needs to be done. Can someone please help?
ANSWER
Answered 2021-Jun-15 at 06:18During the initialization and update processes, the platform looks for ImpEx files in the /resources/impex folder. In particular:
For essential data: The platform scans the /resources/impex folders for files with names that match the pattern essentialdata*.impex and imports the files during the essential data creation.
For project data: The platform scans the /resources/impex folders for files with names that match the pattern projectdata*.impex and imports the files during the project data creation.
The ImpEx directory does not exist by default. You must create it and copy files to it.
For example, if you have the following folder structure:
resources/impex/essentialdataOne.impex
resources/impex/essDataOne.impex

QUESTION
- As of Shiny 1.5.0, we are encouraged to use
moduleServerrather thancallModule. - However, it appears as though we can't pass additional parameters to
moduleServer(unlikecallModule). - This is an issue because I'd like to pass the parent session as a parameter to
moduleServer, so that I can correctly reference the parent session in order forupdateTabsetPanelto work correctly inside arenderUIdynamic output.
This post demonstrates how to use callModule to pass the parent session into the module so that updateTabsetPanel can reference the parent session and update it accordingly. I used that approach to create a minimal example here. There are two tabPanels, and we are trying to navigate to the second via an actionLink in the first. The first_server module is called with callModule, and we are able to pass the parent session parameter as an additional argument, allowing us to reference it in the updateTabsetPanel call in first_server. Clicking the actionLink then takes us to the second module UI, as expected:
ANSWER
Answered 2021-Jun-15 at 02:39Once you remove the extra argument in moduleServer it works. Try this

QUESTION
I have a situation with a Java Socket Input reader. I am trying to develop an URCAP for Universal Robots and for this I need to use JAVA.
The situation is as follow: I connect to the Dashboard server through a socket on IP 127.0.0.1, and port 29999. After that the server send me a message "Connected: Universal Robots Dashboard Server". The next step I send the command "play". Here starts the problem. If I leave it like this everything works. If I want to read the reply from the server which is "Starting program" then everything is blocked.
I have tried the following:
-read straight from the input stream-no solution
-read from an buffered reader- no solution
-read into an byte array with an while loop-no solution
I have tried all of the solution presented here and again no solution for my case. I have tried even copying some code from the Socket Test application and again no solution. This is strange because as mentioned the Socket Test app is working with no issues.
Below is the link from the URCAP documentation:
https://www.universal-robots.com/articles/ur/dashboard-server-cb-series-port-29999/
I do not see any reason to post all the trials code because I have tried everything. Below is the last variant of code maybe someone has an idea where I try to read from 2 different buffered readers. The numbers 1,2,3 are there just so I can see in the terminal where the code blocks.
In conclusion the question is: How I can read from a JAVA socket 2 times? Thank you in advance!
...ANSWER
Answered 2021-Jun-11 at 12:14The problem seems to be that you are opening several input streams to the same socket for reading commands.
You should open one InputStream for reading, one OutputStream for writing, and keep them both open till the end of the connection to your robot.
Then you can wrap those streams into helper classes for your text-line based protocol like Scanner and PrintWriter.
Sample program to put you on track (can't test with your hardware so it might need little tweaks to work):
QUESTION
Assuming I have a cluster with two worker nodes and from these two workers, I have 10 executors. How much memory will be used up in my cluster if I choose to broadcast a 1gb Map?
Will it be 1gb per worker so 2gb in total? Or will it be 1gb per executor so 10gb in total?
Apologies for the simple question, but for me, a number of articles written about broadcast variables aren’t 100% clear on this issue.
...ANSWER
Answered 2021-Jun-14 at 17:17Executers are the entities that perform the actual work. Each executor is its own JVM process with allotted memory.
(As described here: http://spark.apache.org/docs/latest/cluster-overview.html)
The broadcast is materialized at the executer level so in the above example- 10GB.
