kandi X-RAY | operating-system Summary
Home Assistant Operating System (formerly HassOS) is a Linux based operating system optimized to host Home Assistant and its Add-ons. Home Assistant Operating System uses Docker as Container engine. It by default deploys the Home Assistant Supervisor as a container. Home Assistant Supervisor in turn uses the Docker container engine to control Home Assistant Core and Add-Ons in separate containers. Home Assistant Operating System is not based on a regular Linux distribution like Ubuntu. It is built using Buildroot and it is optimized to run Home Assistant. It targets single board compute (SBC) devices like the Raspberry Pi or ODROID but also supports x86-64 systems with UEFI.

QUESTION
I am trying to send a very large string to one of my clients. I am mostly following code in HTTP server example: https://www.boost.org/doc/libs/1_78_0/doc/html/boost_asio/examples/cpp11_examples.html
Write callbacks return with error code 14, that probably means EFAULT, "bad address" according to this link:
https://mariadb.com/kb/en/operating-system-error-codes/
Note that I could not use message() member function of error_code to read error message, that was causing segmentation fault. (I am using Boost 1.53, and the error might be due to this: https://github.com/boostorg/system/issues/50)
When I try to send small strings, let's say of size 10 for example, write callback does not return with an error.
Here is how I am using async_write:
...ANSWER
Answered 2022-Apr-01 at 14:03The segfault indicates likely Undefined Behaviour to me.
Of course there's to little code to tell, but one strong smell is from you using a reference to a non-member as the buffer:

I'm learning web scraping and found a fun challenge scraping a Javascript handlebars table from this page: Samsung Knox Devices
I eventually got the output I wanted, but I think it feels "hacky", so I'd appreciate any refinements to make it more elegant.
Desired output is a dataframe/csv table with columns = Device, Model_Nums, OS/Platform, Knox Version. Don't need anything else on the page, and I will split/expand and melt the Model Nums separately.
...ANSWER
Answered 2022-Feb-28 at 20:22To scrape the texts from the DEVICE and MODEL CODE column you need to create a list of the desired texts using list comprehension inducing WebDriverWait for the visibility_of_all_elements_located() and then write it into a DataFrame using Pandas and you can use the following locator strategies:

QUESTION
I am setting up auto-scale rules in Azure VMSS. I can choose from two set of metrics, Host and Guest. As per the documentation, both are emitted from same VMs.
My tech stack on each VM
...ANSWER
Answered 2022-Jan-20 at 09:58What's the difference between Host and Guest metrics.
- A host operating system is a software that is installed on a computer and communicates with the hardware. A guest OS, on the other hand, is software that is installed in a virtual machine.
- The host OS runs on the hardware directly. The guest OS, on the other hand, runs on a virtual machine.
- It's possible that the host Operating System may be single . The guest OS, on the other hand, can be single or numerous.
- The host operating system interacts with the hardware. The guest operating system interacts with the virtual machine.
Which ones to choose for more accurate scaling of tomcat.
- We can scale up or down using host-level metrics, but we won't be able to do that with guest-level metrics.
- Guest OS metrics include Performance counters which monitor guest CPU % or memory consumption, which are commonly used for autoscaling.
Is there a more efficient way to scale tomcat in Azure VMSS, like system memory.
- You may use Azure Monitor for VMs to automate the collection of essential CPU, memory, disks, and network performance counters from the VMs in your scale set. It also comes with additional monitoring features and pre-built visualisations to help you focus on the performance and reliability of your scale sets.

QUESTION
I am trying to configure a multipath for Oracle Linux 8. I am following the instructions here: https://docs.oracle.com/en/operating-systems/oracle-linux/8/stordev/multipathing.html#about-device-multipath
But even if i define my volume in the /etc/multipath.conf file, the FS does not show up in "multipath -ll"
...ANSWER
Answered 2022-Jan-18 at 17:40multipath.conf refers to disk already discovered by OS - not vice versa.
- Check if disk is zoned to you server on SAN level
- re-scan SCSI "bus" by executing
rescan-scsi-bus.shscript. - check whether disk visible by OS by executing
lsscsi - then check WWN of a disk by executing
multipath -ll - then modify multipath.conf
PS: Linux usually prepends digit "3" to all WWNs. So your stanza from multipath.conf seems to be wrong.

I am trying to bring one of the environments EAP 7.0 to EAP7.4.1 and I have managed to migrate one of the environments successfully. However, on one of the environments, as soon as I start EAP after upgrade in the domain mode, the server runs out of memory with the error below:
...ANSWER
Answered 2021-Oct-26 at 13:21I found the issue, apparently jberet was internally trying to fetch details about the job executions from the table(JDBC repository). And since there was a lot of rows in that table, the committed heap size would run out.
After I deleted rows from that table, the server looks stable and everything runs smoothly. I wonder how the server handles a large load since it is constantly trying to fetch that data. Is there an alternate to the solution?

QUESTION
I've finally cross-compiled and linked a binary on an Ubuntu Xenial x86_64 host to run on the Raspberry Pi 4's armhf.
My toolchain's from ARM and placed in $TOOLCHAIN.
My sysroot is a loop-mounted Raspberry OS image placed in $RASPBIAN_ROOT.
This is a sample compilation line:
...ANSWER
Answered 2021-Sep-27 at 08:29The solution I found was to cross-compile with the toolchain from raspberrypi.org and set --sysroot= to a Raspbian image. Their releases more or less follow Debian's and always support all existing Raspberry Pies.
Both CXX and LD point to their g++, meaning it's GCC who determines linking flags. If necessary I can use -Wl,..
Other than -Wabi-tag -D_GLIBCXX_USE_CXX11_ABI=0, CFLAGS is pretty standard.
Raspbian changed their download URL format between Buster 10.3 (2020-02-13) and 10.4 (2020-05-28) and started providing full and lite versions. I used the latter.
Since these images typically have almost no free space, I first extend the image file, partition (p2) and underlying filesystem, so I can install the -dev packages that satisfy the dependencies of my project by chrooting into the sysroot via quemu-arm.
