notions | Cours et fiches pratiques sur les sujets les plus communs

Currently, I'm working on a project where I need to extract the relevant aspects used in positive and negative reviews in real time.

For the notions of more negative and positive, it will be a question of contextualizing the word. Distinguish between a word that sounds positive in a negative context (consider irony).

Here is an example: Very nice welcome!!! We ate very well with traditional dishes as at home, the quality but also the quantity are in appointment!!!*

Positive aspects: welcome, traditional dishes, quality, quantity

Can anyone suggest to me some tutorials, papers or ideas about this topic?

Thank you in advance.

I'm building a text editor using React with Typescript. The component hierarchy looks like this: TextEditor -> Blocks -> Block -> ContentEditable.

The ContentEditable is an npm package https://www.npmjs.com/package/react-contenteditable.

What i want it to do

The behavior I'm after is similar to Medium or Notions text editor. When a user writes in a block and hits enter on their keyboard, a new block should be created after the current block.

What it does

The behavior right now is strange to me. If I press enter and add one block, it works fine. But if I press enter again it overrides the previous block instead of creating a new one. However, if I press enter and add a block, then puts the carrot (focusing) on the new block and press enter again, a new block is added after as expected.

I am sorry if this question may sound a bit trivial for those who are more expert than me. If I have to create a long positive integer as well as find the number of zeros (with the following instruction as a hint: change the number to a string), do you know what I am supposed to do? Actually, these are some of the notions and examples that I'm focusing on to solve this problem.

I do not know whether the blue highlighted lines may be suitable for the assignment. There is no specified other info (if you are wondering, I have downloaded python 3.10, although typing the command python onto the panel of commands prompt, it pops up that the python's version in use is 3.6.6).

I am very sorry for this kind of question but I have just started moving my first step towards Python.

Thanks

Im trying to create an elegant table as described here but I get the result inside html tags instead of a table.

I have created an EKS cluster and deployed an API. My API needs to connect to a database that is not in AWS. In order to allow my API to use this database, I must authorize it's IP address in a whitelist. My problem is : I don't know how to get this IP adress since applications can be re-deployed and IP adresses can change... I'm not very familiar with networking notions and any detailed help can be very helpful since I don't only want the solution but also to understand how it works..

For an array of n integers, there are C(n,2)= n(n−1)​ / 2 pairs of integers. Thus, we may check all n(n−1)​ / 2 pairs and see if there is any pair with duplicates.

I was poking around a LeetCode question and the answer for one of the algorithms included the above formula in the question explanation.

What is the point of the C(n, 2) nomenclature on the left hand side of the equation? Is this a known/named standard that I can read and interpret, or is this some more general information that must/should be ascertained from context? I understand the math on the right, but I don't have any preconceived notions that adds any detail to my understanding from the function on the left.

What is the 2 doing?

I'm trying to create a well-formatted correlation matrix table with negative and positive values aligned. It would be great if there is a way to add whitespace before the positive values so that we can left-align them. But I'm stuck. Ideally I would like to achieve it with just tableOutput for shiny, but if there are other packages, I'm open to that as well.

Recording my desktop with ffmpeg (specially on Windows, less on Linux) I meet situations where/when ffmpeg complains about real time buffer size or thread queue size. I understand that the queue size is the number of frames that can reside in the queue and thus I am incited to think that it increases the buffer size as well. Can someone clarify these notions to me ?

In the documentation :

BATCH: Commit the offset when all the records returned by the poll() have been processed.

MANUAL: The message listener is responsible to acknowledge() the Acknowledgment. After that, the same semantics as BATCH are applied.

if the offset is committed when all the records returned by the poll() have been processed for both cases then I don't get the difference, can you give me a scenario when MANUAL ack mode is used differently ?

If I use MANUAL mode and I don't call acknowledge() within my KafkaListener would be the same as BATCH mode ? and if I call acknowledge() what would change ?

Maybe I don't get the difference between commit and acknowledge notions within spring kafka
