I have three different boxplots:

That I plot with the following code:

I'm using Tomcat 10 and eclipse to develop a J2E (or Jakarta EE) web application. I followed this tutorial (http://objis.com/tutoriel-securite-declarative-jee-avec-jaas/#partie2) which seems old (it's a french document, because i'm french, sorry if my english isn't perfect), but I also read the Tomcat 10 documentation.
The dataSource works, I followed instructions on this page (https://tomcat.apache.org/tomcat-10.0-doc/jndi-datasource-examples-howto.html#Oracle_8i,_9i_&_10g) and tested it, but it seems that the realm doesn't work, because I can't login successfully. I always have an authentification error, even if I use the right login and password.
I tried a lot of "solutions" to correct this, but no one works. And I still don't know if I have to put the realm tag inside context.xml, server.xml or both. I tried context.xml and both, but i don't see any difference.

My web.xml :

I'm not sure if the title makes sense, it was the best I could come up with, so here's my scenario.

I have an ASP.NET Core app that I'm using more as a shell and for DI configuration. In Startup it adds a bunch of IHostedServices as singletons, along with their dependencies, also as singletons, with minor exceptions for SqlConnection and DbContext which we'll get to later. The hosted services are groups of similar services that:

1. Listen for incoming reports from GPS devices and put into a listening buffer.
2. Parse items out of the listening buffer and put into a parsed buffer.

Eventually there's a single service that reads the parsed buffer and actually processes the parsed reports. It does this by passing the report it took out of the buffer to a handler and awaits for it to complete to move to the next. This has worked well for the past year, but it appears we're running into a scalability issue now because its processing one report at a time and the average time to process is 62ms on the server which includes the Dapper trip to the database to get the data needed and the EF Core trip to save changes.

If however the handler decides that a report's information requires triggering background jobs, then I suspect it takes 100ms or more to complete. Over time, the buffer fills up faster than the handler can process to the point of holding 10s if not 100s of thousands of reports until they can be processed. This is an issue because notifications are delayed and because it has the potential for data loss if the buffer is still full by the time the server restarts at midnight.

All that being said, I'm trying to figure out how to make the processing parallel. After lots of experimentation yesterday, I settled on using Parallel.ForEach over the buffer using GetConsumingEnumerable(). This works well, except for a weird behavior I don't know what to do about or even call. As the buffer is filled and the ForEach is iterating over it it will begin to "chunk" the processing into ever increasing multiples of two. The size of the chunking is affected by the MaxDegreeOfParallelism setting. For example (N# = Next # of reports in buffer):

• N3 = 1 at a time
• N6 = 2 at a time
• N12 = 4 at a time
• ...

• N6 = 1 at a time
• N12 = 2 at a time
• N24 = 4 at a time
• ...

• N12 = 1 at a time
• N24 = 2 at a time
• N48 = 4 at a time
• ...

• N24 = 1 at a time
• N48 = 2 at a time
• N96 = 4 at a time
• ...

This is arguably worse than the serial execution I have now because by the end of the day it will buffer and wait for, say, half a million reports before actually processing them.

Is there a way to fix this? I'm not very experienced with Parallel.ForEach so from my point of view this is strange behavior. Ultimately I'm looking for a way to parallel process the reports as soon as they are in the buffer, so if there's other ways to accomplish this I'm all ears. This is roughly what I have for the code. The handler that processes the reports does use IServiceProvider to create a scope and get an instance of SqlConnection and DbContext. Thanks in advance for any suggestions!

I'm new to php and sql and I'm trying to build a new user system. I've tried two different methods and they both give me errors.

$_SERVER["REQUEST_METHOD"] == "POST" gives me an unidentified index 'Nom', 'Prenom', 'Role' and 'Mail' error

and isset($_POST['submit']) does not enter the if (doesn't print the test2)

So I'm guessing I have a problem with the form but I can't figure out what it is.

Edit : New problem : The sql query doesn't go through so the data isn't added into the database. I get this error message :Une petite erreur, veuillez réessayer plus tard ! aka the one from my last if else statement in the .php file

This is my html code (a form to collect data) :

So hi, I'm actually a very very beginner and i'd like to know how to set a property that is in a class as a variable to do condition?

I am running the following slurm script on a cluster computing system.

I woudlike to execute GET request :

I woudlike to put some parameter in my request (code value and name value) :

I'm still new to C, so I don't have a great understanding of it. Right now I'm trying to figure out pointers.

I want to load the parameters of a structure amqp_connection_info through the argv variables. How can I change the load of parameters in the structure?
