How can I combine custom filter functions, custom selectSource and dynamic table population?

Asked 2021-May-25 at 23:21

I'm trying to combine the approach from this answer for adding a custom filter option for selecting empty cells with a table which is populated dynamically. Unfortunately I'm finding that after an update to the content of the table, the dropdown is not being repopulated with the updated options from the data.

I've created an example here which illustrates the problem. Initially the table contains just 3 rows and the filter dropdown for the first column correctly shows those options, along with the "(Empty)" option for filtering down to just the empty rows.

After clicking the button which adds a bit more data to the table, the filter dropdown for the "Custom" should now contain the additional options ("biscuit" and "sausages") along with those which existed before - like the "Default" column does. Unfortunately that doesn't happen.

Probably not an ideal solution - I haven't looked at the code in a while, so I can't remember the optimal way to update the selects - but this method works:

How can I find which category has the most products shipped and the net income from sales in that category?

Asked 2021-Feb-03 at 00:55

Using the w3schools.com SQL tutorial Northwind database, I'm trying to display the category that has the most products shipped. Additionally, I want to display the net income from all sales in that category. I can't figure out how to take the category with the most products shipped, and use the amount of products shipped to calculate the net income of that category. This is because there are many different products that have the same CategoryID but different prices.

ANSWER

Answered 2021-Jan-25 at 07:24

So first of all you get the income for each product and category and then based on that you find total income for that category and you do this with the help of subquery, then you join this resultant table with the category table and with the help of group by you find the product count and total income for each category, below is the sql query for more indepth understanding

I'm brand new in MySQL and I need some help how to build simple query. I need to get some result selecting "filtered" data from one table linked with another table based on conditions inside this second table.

Random lack of connection and message delay in DTLS with OpenSSL

Asked 2021-Jan-12 at 08:27

Trying to write a server for DTLS that will currently just output the text that it receives. The working client is taken from https://github.com/stepheny/openssl-dtls-custom-bio and it sends and receives to its own server just fine.

However, when it sends to this server something strange is happening. Firstly the connection happens only sometimes, there seems to be no way to determine if the connection will start or not. Secondly, and that is even stranger the data is "delayed". One needs to send 6 messages for 1 message to arrive.

So this is the situation:

Start the server.
Start the client.
Hope for connection.
If connected type 5 messages in client to send to server, they are sent, but the server keeps having an error decoding them.
Once you send the 6th message you can note that the 1st message arrives on server.
Once you send the 7th, you will get the 2nd. Etc.

It should be noted that we are not talking about a time delay, there is no way to simply read 5 empty messages at the start of the server, the queue is empty. Only once the 6th message is sent is the queue populated with the 1st real message.

Code:

ANSWER

Answered 2021-Jan-12 at 08:27

In case somebody else will have a similar issue. The problem was that the wait between calling server's recv function was 1 second. In that time client thought that server has not responded and began doing weird things. Lowering the delay solved the problem.

Axon Event Sourcing not generating table

I am learning how to use the axon framework for event sourcing, seems to be going good but I have gotten stuck on the database configuration for event sourcing. From what I understood from docs / other articles, the database table should automatically generate.

ANSWER

Answered 2021-Jan-07 at 08:27

In this case, you should instruct your application how to create tables.

You have 2 options:

Tell JPA to do that, adding spring.jpa.hibernate.ddl-auto=create or spring.jpa.hibernate.ddl-auto=update
Use a more robust tool like flyway, liquibase, etc

All the other configs you showed looks fine.

Crop colour image according to OTSU threshold

Asked 2020-Dec-22 at 20:28

I have a colour image which I have sucessfully applied the OTSU thresholding method on its greyscale form to obtain the outline of the biscuit:

Original Colour image:

OTSU Thresholded image:

What I would like to do is extract from the colour image only the pixels within the black portion of the OTSU thresholded image, and save that as a new picture. So far, I have tried to extract using the BITWISE_NOT method and using 'thresh_inv' as the mask, however that only results in this image (greyscale + extra black background). I have also tried using the cannny contours method to identify the rough outline of the biscuit circle, and then drawing the contours over a blank image to hopefully try and overlay that over the original colour picture. This has also not worked.

Here is my code so far, I would greatly appreciate any help as I've been trying to figure it out for ages.

ANSWER

Answered 2020-Dec-22 at 19:39

1st load the image as rgb. Then convert it into binary. since it has 3 channel then you need to stack your mask to form a array with 3 channel Then perform binary and operation on them.
