            How to send a signal around specific processes?
            Asked 2021-Jun-11 at 09:14

            I'm trying to send a signal around circle of processes for a certain amount of times. my first argument represents the number of processes I wish to create. my second one is just a place holder I am currently initiating to be 0. My third is the number of time I want to pass this signal around. I have designed the processes to have a relationship as such: Parent->child1, child1->child2, child2->child3.... and so on. I'm just figuring out C and I'm confused to why my code is stopping midway. It runs for an iteration or two and then stalls out. Can someone explain why?

            stalls out. Can someone explain why?

            The final child is not woken up from sigsuspend(&killSet) because you did sigaddset(&killSet,SIGUSR1); - you seem to have thought you have to add the signal to be waited for to the set, but on the contrary the signals in the given set are blocked from delivery. So just drop the sigaddset call.

            • you can't use keys like under without defining the,

            • south south is not a valid anchor point

            • you can only use the coordinates of non-empty cells

            A quick workaround will be: to check

            time.timezone.substring(0, 4) ==="(GMT"

            and if true add GMT to the returned value before "PM" / "AM"

            How do I get values instead of keys from object for use with vue.js binding (:class)
            Asked 2021-May-16 at 07:57

            I'm very new to Vue syntax, so please forgive me (and feel free to correct!) my terminology and assumptions. In short, I have a very simple goal, to get values from an object where currently I am getting key names.

            In the code I am trying to modify, there is a Vue object called "tags," part of a complete "video" object (returned from Vimeo), that, when bound in a Vue "x-template" script to html - like so:



            Answered 2021-May-16 at 02:49

            couldn't get your problem exactly, if you want to print the value call it by its property name ".name" as you did, but you have to be sure that video is a single object.

            What is a common use case for Apache arrow in a data pipeline built in Spark
            Asked 2021-May-11 at 21:23

            What is the purpose of Apache Arrow? It converts from one binary format to another, but why do i need that? If I have a spark program,then spark can read parquet,so why do i need to convert it into another format,midway through my processing? Is it to pass that data in memory to another language like python or java without having to write it to a text/json format?



            Answered 2021-May-11 at 21:23

            Disclaimer: This question is broad and I am somewhat involved with the Apache Arrow project so my answer may/or may not be biased.

            This question is broad in the sense that a question like a "When should I use NoSQL?" type of question is broad. It depends. This answer is based on the assumption that you already have a Spark pipeline. This answer is not an attempt at Spark Vs. Arrow (which is even broader to the point I wouldn't touch it).

            Many Apache Spark pipelines would never need to use Arrow. Spark, unlike Arrow-based pipelines, has its own in-memory dataframe format (https://spark.apache.org/docs/1.6.1/api/java/org/apache/spark/sql/DataFrame.html) which, to my knowledge, cannot be zero-copied to Arrow. So converting from one format to the other is likely to introduce a performance hit of some kind and any benefit you achieve is going to have to be weighed against that.

            You brought up one great example, which is switching to other languages / libraries. For example, Spark currently uses Arrow to apply a Pandas UDF (https://spark.apache.org/docs/latest/api/python/user_guide/arrow_pandas.html). In this case, whenever you are going to a library that doesn't use Spark's in-memory format (which means any non-Java library and some Java libraries) you are going to have to do a translation between in-memory formats and so you are going to pay the performance hit anyways and you might as well switch to Arrow.

            There are some things that are faster with Arrow's format than Spark's format. I'm not going to try and list those here because, for the most part, the benefit isn't going to outweigh the cost of going Spark -> Arrow in the first place and I don't know that I have enough information to do so in any sort of comprehensive way. Instead, I'll provide one concrete example:

            A common case for Arrow is when you need to transfer a table between processes that are on the same machine (or have a very fast I/O channel in between). In that case the cost of serializing to parquet and then deserializing back (Spark must do this to go Spark Dataframe -> Parquet -> Wire -> Parquet -> Spark Dataframe) is more expensive than the I/O saved (Parquet is more compact than Spark Dataframe so you will save some in transmission). If you have a lot of this type of communication it may be beneficial to leave Spark, do these transmissions in Arrow, and then return to Spark.

            Running multiple Bash commands interactively from Python
            Asked 2021-May-10 at 21:04

            I have just come across pexpect and have been figuring out how to use it to automate various practices I would otherwise have to fill in manually in a command shell.

            Here's an example script:



            Answered 2021-May-10 at 21:04

            You don't need to wait for # between each command. You can just send all the commands and ignore the shell prompts. The shell buffers all the inputs.

            You only need to wait for the username and password prompts, and then the final # after the last command.

            You also need to send an exit command at the end, otherwise you won't get EOF.

            Multiple Instances of my Foreground Service When Android Phone is Rotated
            Asked 2021-May-05 at 09:36

            I'm writing an Android location app and foreground service. The app gets location updates from the service periodically. I'm using Android Studio and writing the app in Kotlin.

            The problem is that when the phone is rotated a new instance of the foreground service is created. This is demonstrated with Log outputs that show the count of location updates as well as the hash code of the service:



            Answered 2021-May-05 at 09:36

            After many hours of debugging I found the problem:

            In MainActivity.onDestroy() I was attempting to stop my Service LocationService. The problem is that I attach a location callback to the Service and therefore the Service is leaked when the phone is rotated because MainActivity.onDestroy() is called which attempts to stop the service but can't apparently because of the attached Location Listener and Android seems to assume that it successfully stopped the service and so creates a new instance of it the next time around.

            constant resident memory increase in golang with multiple concurrent tls dialers
            Asked 2021-May-02 at 23:41

            Alright so this has been plaguing me for weeks and I can't figure out what I'm missing or where this leak is or if it even exists. I have a fairly simple workload. Take a list of URLs, spin up a pool of goroutines that pull URLs from achannel and create a tls connection to them with tls.Dialer. Below is a snapshot of the memory graph showing the constant rise and a POC of my code.

            My guess is it's something to do with the allocations done by the tls package because it seems to only climb the more "successful" URLs it connects to. I.E. if most of them don't connect I don't see a steady memory increase.

            Here is a pprof output from midway through the run:



            Answered 2021-May-02 at 23:41

            Turns out the code in //do something with connection was more important than I thought. Even at the tls.Dial level you have to read off the "body". My, now obviously wrong assumption, was that tls.Dial just setup the connection and that since a GET / HTTP 1.1 request hadn't been sent yet no data needed to be read off the wire. This was causing all those buffers full of server response to sit around.

            _, _= ioutil.ReadAll(tConn) fixed it all in one line. I feel much wiser and also dumb at the same time. As a side note, at this level, ReadAll() can hang for a long time if the server responds slowly. tConn.SetReadDeadline(time.Now().Add(time.Second * timeout)) solved that too.

            how to display cities in one dropdown based on selected state in other dropdown using json data in angular ionic?

            following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.

            //.ts file



            Answered 2021-Apr-27 at 16:44

            You can do it with the $event parameter. Make sure to compare your values safely.

            If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.

            You can use the trim function to compare your value safely: c.state.trim() == val.trim()
