QUESTION
How can I paste the data (row and column) passed by the function makeRequest to google sheet.
I am retrieving the data from HTML storing that into an object and passing that object like this makeRequest(facebookAccountData).
I can use something like this below to paste data (row and column) to sheet but in my case user will define which fields he requires. So I want to make this dynamic which I am not able do so.
...ANSWER
Answered 2021-Jun-11 at 07:25In your situation, how about the following modification? I thought that when setValues is used instead of appendRow, the process cost will be able to be reduced a little. Ref
QUESTION
I'm trying to understand best practices for Golang concurrency. I read O'Reilly's book on Go's concurrency and then came back to the Golang Codewalks, specifically this example:
https://golang.org/doc/codewalk/sharemem/
This is the code I was hoping to review with you in order to learn a little bit more about Go. My first impression is that this code is breaking some best practices. This is of course my (very) unexperienced opinion and I wanted to discuss and gain some insight on the process. This isn't about who's right or wrong, please be nice, I just want to share my views and get some feedback on them. Maybe this discussion will help other people see why I'm wrong and teach them something.
I'm fully aware that the purpose of this code is to teach beginners, not to be perfect code.
Issue 1 - No Goroutine cleanup logic
...ANSWER
Answered 2021-Jun-15 at 02:48It is the
mainmethod, so there is no need to cleanup. Whenmainreturns, the program exits. If this wasn't themain, then you would be correct.There is no best practice that fits all use cases. The code you show here is a very common pattern. The function creates a goroutine, and returns a channel so that others can communicate with that goroutine. There is no rule that governs how channels must be created. There is no way to terminate that goroutine though. One use case this pattern fits well is reading a large resultset from a database. The channel allows streaming data as it is read from the database. In that case usually there are other means of terminating the goroutine though, like passing a context.
Again, there are no hard rules on how channels should be created/closed. A channel can be left open, and it will be garbage collected when it is no longer used. If the use case demands so, the channel can be left open indefinitely, and the scenario you worry about will never happen.
QUESTION
There is a Java 11 (SpringBoot 2.5.1) application with simple workflow:
- Upload archives (as multipart files with size 50-100 Mb each)
- Unpack them in memory
- Send each unpacked file as a message to a queue via JMS
When I run the app locally java -jar app.jar its memory usage (in VisualVM) looks like a saw: high peaks (~ 400 Mb) over a stable baseline (~ 100 Mb).
When I run the same app in a Docker container memory consumption grows up to 700 Mb and higher until an OutOfMemoryError. It appears that GC does not work at all. Even when memory options are present (java -Xms400m -Xmx400m -jar app.jar) the container seems to completely ignore them still consuming much more memory.
So the behavior in the container and in OS are dramatically different.
I tried this Docker image in DockerDesktop Windows 10 and in OpenShift 4.6 and got two similar pictures for the memory usage.

...ANSWER
Answered 2021-Jun-13 at 03:31In Java 11, you can find out the flags that have been passed to the JVM and the "ergonomic" ones that have been set by the JVM by adding -XX:+PrintCommandLineFlags to the JVM options.
That should tell you if the container you are using is overriding the flags you have given.
Having said that, its is (IMO) unlikely that the container is what is overriding the parameters.
It is not unusual for a JVM to use more memory that the -Xmx option says. The explanation is that that option only controls the size of the Java heap. A JVM consumes a lot of memory that is not part of the Java heap; e.g. the executable and native libraries, the native heap, metaspace, off-heap memory allocations, stack frames, mapped files, and so on. Depending on your application, this could easily exceed 300MB.
Secondly, OOMEs are not necessarily caused by running out of heap space. Check what the "reason" string says.
Finally, this could be a difference in your app's memory utilization in a containerized environment versus when you run it locally.

QUESTION
I am new into RxJava and I was under the impression that for each event each subscriber is being notified. So if we have N subscribers and a stream of X events the onNext for each of the N subscribers would be called. But when I run the following code:
ANSWER
Answered 2021-Jun-13 at 08:05RxJava sequences are synchronous by default thus the subscribe call above will run your emission code right there. To achieve the interleaving, you need a way to tell the source when both consumers are ready to receive. This can be done several ways:
QUESTION
I'm writing a python script and am using PyTest to test it. So far I have written one test for one function within the script (it's a mess so I didn't post it). I was under the impression PyTest would only run the function that is being tested. However, when running PyTest all the code in the script is being executed. Is this intended?
...ANSWER
Answered 2021-Jun-12 at 23:23I assume the problem is that your tested python script contains instructions at root level. When you import a module, python runs the code.
I've set up a simple example.

QUESTION
I have database trigger that sends messages to Service Broker Service. To send a message, conversation has to be created first because that is how Service Broker works (messages are sent on the conversation between the services). I read that conversations should be reused because creating new conversation each time can have bad impact on performance and number of conversations can grow to much. Whether or not I will reuse conversations, I have to create at least first conversation. Beginning conversation has following syntax:
...ANSWER
Answered 2021-Jun-11 at 14:14Service Broker requires a service for both initiator and target. Your trigger is the from initiator service so you should create a service and queue for that. However, the trigger does not need to implement receiving messages from the initiator queue.
You can have a separate process (perhaps a scheduled batch process) to monitor the initiator queue for unexpected error and end dialog messages, and perhaps start a new long-running conversation when needed.
QUESTION
I have the follow situation:
- One layout with TabLayout, ViewPager and advertising banner on bottom
ANSWER
Answered 2021-Jun-11 at 05:24Is it better for me to display ads by screen or by tabs?
eCPM doesn't change much with ad placement ( on same screen ), it will definitely have impact. Recommend to play around with admob placement on various screens and measure the performance of each advert by monitoring the analytics.
There are various other factors for eCPM calculation like Country where advertisement is displayed ( e.g. an advert displayed in USA vs ad displayed in India will have different eCPM value). You app category ( game vs education app or kids category app ).
Rather than thinking about eCPM. Always think from user perspective, loading lot of advertisement gives a bad user experience and app retention might be impacted with it. Also prevent placing ad where users might click it accidentally.
Refer to this guideline for Discouraged banner implementation. https://support.google.com/admob/answer/6275345?hl=en&ref_topic=2936214
There are log of good resources provided by google to understand ad placement and how to boost your revenue with minimal disruption to end user. https://admob.google.com/home/resources/
Also rewarded ad is another good option to explore for increasing the ad revenue.

In order not to have to remember to delete, we are using unique_ptr to manage the memory. We were under the impression that we can write and read in the memory, just that deletion is up to the smart pointer. However, the following code crashes on i=7220 with a segfault.
