            I was expecting segmentation fault or some kind of out of bound exception but did not get it when using command line arguments in a C program
            Asked 2021-May-30 at 09:48

            I am learning C programming from "Learn c the hard way by Zed Shaw". He asks the learner to try and break their own code.

            So I tried the following C code and thought printing more values that I gave argv will break it but it did not until later.



            Answered 2021-May-30 at 09:48

            A segmentation fault happens when the code try to access a memory region that is not available.

            Accessing an array out of bounds doesn't means that the memory before or after the area occupied by the array is not available: The compiler or the runtime usually put all varibales or data in general in a given block of memory. If your array is the last item of such a memory block, the accessing it with a to big index will produce a Segmentaion Fault but is the array is in the middle of the memory block, you will just access memory used for other data, giving unexpected result and undefined behavior.

            If the array (In may example, but valid for anything) is written, accessing available memory will not produce a segmentation fault but will overwrite something else. It may produce unexpected results or crash or segmentation fault later! This kind of bug is frequently very difficult to find because the unexpected result/behavior looks completely independent of the root cause.

            JAVA YAML read/write subset of variables in data structure
            Asked 2021-Feb-22 at 22:12

            I am writing a JAVA program that backs up the data in a data structure to a YAML file. However, this data structure omits protected data for read/write access from the user. Is there a way to setup custom data types or flag the Jackson yaml library to only read/write certain variables in a data structure?

            Below is some test code I have been working on.

            In order to use the constructor when deserializing, you need to annotate the parameters with @JsonProperty in order to name the parameters for the deserializer.

            Looks like you are missing libssl-dev. Just open your terminal and run the command sudo apt install libssl-dev. You might have missed the buildozer dependencies. So even after installing libssl-dev you get error then try running the following command:

            I'm trying to build an apk out of a simple kivy python file however I get this error when using the command "buildozer -v android debug" to build the apk.

            I'm running on a Ubuntu virtual machine, java jdk is version 8 something, I was using version 14 earlier, but saw some post talking about needing version 8. Not entirely sure though if it was for the same problem that I'm facing.

            You were missing libffi-dev earlier and now you are missing libssl-dev. Looks like you might be missing other requirements for buildozer too. Follow the steps given in buildozer documentation

            This is my first kivy project and i really need some help to make it possible

            This is the code



            Answered 2020-Dec-18 at 12:12

            I guess you have your files in a directory named 'Lunar Aplocon'. The space ' ' in the file name is causing the issue. Even when you enter the name in your buildozer.sec file try not to include any space (you can include in title but not in org and other info). So you just have to rename your directory then it will be just fine.

            ValueError: storage dir path cannot contain spaces, please specify a path with --storage-dir

            As it says, try using a directory without spaces in its name.

            Docker: Cannot start docker daemon, cannot kill container
            Asked 2020-Dec-02 at 12:45

            So I'm having this issue where Docker has decided to keel over on my Ubuntu 20.04 virtual machine, hosted on VirtualBox.

            When I first boot my VM, no docker commands work at all. Even basic commands such as docker help and docker version hang indefinitely, as do system commands that interact with docker (for example, sudo service docker [options] will hang).

            I tried sudo dockerd --debug, through which I found out that the var/run/docker.pid file was the issue:



            Answered 2020-Dec-02 at 12:45

            Docker containers are stored in the default location at /var/lib/docker/ on Linux. If you can identify the container and delete this, and then try to start docker. If you are successful and can enter docker ps -a, then you can start deleting traces of this container.

            Note: I would snapshot your VM before attempting to try this.

            I believe the problem is you are running command on 32bit operating system. As mentioned in the BUG #1007

            Thanks, I saw the logs.. But The Problem was that I was using a 32 bit linux system. So the drivers could not work. Then when I tried the same thing in a 64 bit linux system. Installed on virtual machine it worked fine. Thanks for your help.

            On modern Linux systems, environment values are "kind-of" stored on the stack -- for specific values of "kind-of".

            The actual strings that make up the environment are stored at the top (highest-numbered addresses) of the process's virtual address space, along with other environmental data. The stack proper begins immediately below this. The addresses of the individual environment variables are pushed onto the stack by the kernel's program loader, along with the argc and argv values.

            This close correspondence between the environment and the stack leads many writers to talk about the environment being "on the stack" although, strictly speaking, only the addresses of the specific environment values are properly on the stack. Diagrams of the Linux process address space often show the stack at the top of memory, although if you run pmap on a process, you'll see that this isn't usually the case -- there will be one or two segments above the stack proper, and the environment variables will be found in one of these.
