Or Did I just misunderstood the use case for Loom ? Thanks in advance Addon How is it different from regular threads, at least for OS threads I can scale it to thousand to increase the throughput. 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. Instead, virtual threads automatically give up (or yield) their carrier thread when a blocking call (such as I/O) is made. According to Ben Evans in the article Going inside Java’s Project Loom and virtual threads: Now let's say I switched a thread pool to use virtual threads instead. So if I have 200 hundred users reaching this endpoint, I need to create 200 threads each waiting for IO. 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 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. I was investigating how Project Loom works and what kind of benefits it can bring to my company. #Uninstall ransomwhere codeInstead you want the rolling sum over the past year and divide that by the number of days in the year, per my code above. I've had a look at your code and I don't think that the use of the pct_change function is correct - that will calculate the change on the rolling differential, so a movement from eg 0.10% to 0.11% would actually equate to a 10% change. Please also note the article cited states that "It was reported that it had correctly predicted a significant stock market decline only 25% of the time." so I'm not sure if we can read too much into this. So from a look at our graph, my interpretation is that the stock market is currently closing at a lot of 52 week highs, but is not showing many 52 week lows. It would be abnormal if both were occurring at the same time." ,įrom the Hindenburg Omen Definition, "The Hindenburg Omen looks for a statistical deviation from the premise that under normal conditions, some stocks are either making new 52-week highs or new 52-week lows.
