            I believe the only way to get draft campaigns is below:

            1. You should get all addrafts. On my account I have only 1 addraft that contains all draft campaigns, but maybe you can have more. URL for getting addrafts:

            https://graph.facebook.com/v12.0/act_/addrafts?access_token=&fields=name,ad_object_id,id

            1. Now you can get addraft_fragments. You can see all draft fragments of your ad_account (campaigns, adsets, ads), but you can easily find here what you want. URL for getting addraft_fragments:

            How to implement the Hindenburg omen indicator?
            Asked 2021-Dec-21 at 02:21

            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%

            Interesting question! Could I suggest the following code - it runs much faster than the apply solution because it is vectorised, and also lays out the steps a bit more clearly so you can inspect the interim results.

            I got a different result to your code - you can compare by also plotting your result on the timeseries at bottom.

            jQuery .append doesn't work with $(document).ready
            Asked 2021-Dec-19 at 18:08

            This is a followup to toggleClass of parent div not changing with onClick

            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?

            Project loom, what happens when virtual thread makes a blocking system call?
            Asked 2021-Nov-30 at 21:58

            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

            Addon

            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 ?

            Your first excerpt is missing the important point:

            Instead, virtual threads automatically give up (or yield) their carrier thread when a blocking call (such as I/O) is made. This is handled by the library and runtime [...]

            The implication is this: if your code makes a blocking call into the library (for example NIO) the library detects that you call it from a virtual thread and will turn the blocking call into a non-blocking call, park the virtual thread and continue processing some other virtual threads code.

            Only if no virtual thread is ready to execute will a native thread be parked.

            Note that your code never calls a blocking syscall, it calls into the java libraries (that currently execute the blocking syscall). Project Loom replaces the layers between your code and the blocking syscall and can therefore do anything it wants - as long as the result for your calling code looks the same.

            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?

            A common approach that I use myself is to separate the business logic into its own file myComponentHelper.js

            This will also make it easier to test the function because it will not be able to use and change the react state without having it passed in as arguments and returning the changes.
