moulin | reliable queue for batch processing

I use Spring Cloud Data Flow to set up a stream that read a CSV file, transform it using a custom processor and log it :

I have a set of stimuli (statements), half of them are true and half are false. I'd like to randomly assign them to 4 sets containing an equal number of statements, of which half are true and half false statements.

Here's what I've got so far, but I need to add that the randomisation to the 4 sets shoudl be based on the contents a specific binary column (i.e., whether the statement is true or false):

I'm trying to calculate the distance between points and the closest polygon for each point. I'm currently using the function st_distance (library sf), that seems the fastest method to do that. But it's still taking a lot of time. That's why I want to change the loop for that I'm using into an apply procedure or in a way to do this faster. Could somebody help me to do that please ? Thanks !

I'm trying to make an component which has two TextInput's :

• Number of the street
• Name of the street

I want the first one to have a width of 35 and the second one to fill the remaining space horizontally.

How would you do that ?

My code:

I have this code to get total and other fields. what I am interested in to get total values with $ sign, comma and 02 decimal places, what will be the best function to use to cover all these. so the total should reflect like : $ 1,780.00

please advise

As the title clearly describes, we resultset.hasNext() returns false unexpectedly.

Here is my SPARQL query and Java source code based on Jena:

I'm trying to make a report on a set of data I gathered for a mining company.

Each day, a mining project will send data from their mine and mill. The data is made up of 3 sets of readings: what they produced, what they planned for that day, and what's the monthly target. Monthly target stays the same for the month, daily target is usually constant for the month but can change in special circumstances.

So I made a readings table for milling and mining and I combine 3 instances into the mining/milling report.

Here is the relationships graph of my database:

Now I want to calculate the percentage obtained for each reading. So I need to take the production readings and divide them by their equivalent daily target.

Problem is, I'm pretty much a noob at SQL and Access

I'm still at the point of trying to join the 3 readings tables for mining/milling of a single report. I've tried this:

I have a problem with my code for a work, I actually use a JSON API of vehicle park information:

When I use curl for GET the JSON like this:

i have a bit problem,

i need to get the coordinates of a place from the name of the road (what i provide), i try to do it with file_get_contents & json_decode, but some of them don't work (return a stdClass with ZERO_RESULTS) !

if i copy paste the url (exaclty the same) in the browser, it send me the right data, doesn't know why.

if i try with a another road name, it works.

obviously i already tried to clear the cache, but no result, change the navigator doesn't work too, tried on multiple servers too, but still no results, tried to do it with CURL (as provided as an answer in a post relating the same problem), but still, no result.

i'm quite lost, i hope you can help me with this.

here the code.

The data provided is from France road names, you can add "France " in the $a if you want to see it
