I'm following the Sort Model documentation (https://material-ui.com/components/data-grid/sorting/#basic-sorting) and am using sortModel and onSortModelChange exactly as used in the documentation. However, I'm getting an infinite loop immediately after loading the page (I can tell this based on the console.log).

What I've tried:

• Using useCallback within the onSortChange prop
• Using server side sorting (https://material-ui.com/components/data-grid/sorting/#server-side-sorting)
• Using if (sortModel !== model) setSortModel(model) within the onSortChange function.

I always end up with the same issue. I'm using Blitz.js.

I have an odd problem, where I am struggling to understand the nature of "static context" in Java, despite the numerous SO questions regarding the topic.

TL;DR:

I have a design flaw, where ...

This works:

I'm trying to list all of my draft campaigns using the Facebook marketing API. By default, it seems, only non-draft (published?) campaigns are listed when calling

As defined here the Hindenburg omen indicator is:

The daily number of new 52-week highs and 52-week lows in a stock market index are greater than a threshold amount (typically 2.2%).

To me it means, we roll daily and look back 52 weeks or 252 business/trading days, then count the number of highs (or lows) and finally compute the return of that or pct_change, which is the ratio of new highs (or lows) they want to monitor e.g., being above 2.2%

In my HTML layout, I've found that I need to generate the div #filters after the records, not before, because I need to use PHP to build the buttons for each state. This gave me the idea to use jQuery .append to move the #filters to the #move-filters-here above the records. But after I filter on a state, the filters appear below the records and .append doesn't work to move the #filters to #move-filters-here above the records.

Is .append not working with (document).ready?

Is there a different way to get .append to move the #filters?

Does .append need to "fire" again after the Onclick function?

I was investigating how Project Loom works and what kind of benefits it can bring to my company.

So I understand the motivation, for standard servlet based backend, there is always a thread pool that executes a business logic, once thread is blocked because of IO it can't do anything but wait. So let's say I have a backend application that has single endpoint , the business logic behind this endpoint is to read some data using JDBC which internally uses InputStream which again will use blocking system call( read() in terms of Linux). So if I have 200 hundred users reaching this endpoint, I need to create 200 threads each waiting for IO.

Now let's say I switched a thread pool to use virtual threads instead. According to Ben Evans in the article Going inside Java’s Project Loom and virtual threads:

Instead, virtual threads automatically give up (or yield) their carrier thread when a blocking call (such as I/O) is made.

So as far as I understand, if I have amount of OS threads equals to amount of CPU cores and unbounded amount of virtual threads, all OS threads will still wait for IO and Executor service won't be able to assign new work for Virtual threads because there are no available threads to execute it. How is it different from regular threads , at least for OS threads I can scale it to thousand to increase the throughput. Or Did I just misunderstood the use case for Loom ? Thanks in advance

I just read this mailing list:

Virtual threads love blocking I/O. If the thread needs to block in say a Socket read then this releases the underlying kernel thread to do other work

I am not sure I understand it, there is no way for OS to release the thread if it does a blocking call such as read, for these purposes kernel has non blocking syscalls such as epoll which doesn't block the thread and immediately returns a list of file descriptors that have some data available. Does the quote above implies that under the hood , JVM will replace a blocking read with non blocking epoll if thread that called it is virtual ?

I work with some business logic written in Kotlin. I've got such a case in my method - I check a value for null, and if it IS null - I want to return null, else do some logic. My version looks like:

I have the following df:

I am new to react and I find it sore in the eyes to look at the component flooded with lots of functions and variable initializations together with the UI. Is it possible to separate them?

Instead of the default setup, like below. How do I separate the business logic into another file?
