kandi X-RAY | stw Summary
stw is a simple text window for X. Here stw runs pstree and renders its output above desktop wallpaper. stw mostly resembles watch command: it creates an unmanaged X window at specified position and starts subcommand. If subcommand terminates, stw sleeps specified number of seconds and restarts it. If stw X window is clicked, stw terminates subcommand and restarts it immediately. stw buffers subcommand output. When output line matches specified delimeter line or subcommand terminates, stw renders collected output. Each time stw renders, it clears both collected output and X window. It is possible to specify font, text align, text color, background color, opacity, window position, border width, sleep period via command line arguments or config.h file.

I am trying to use externel toolchain option in Buildroot and to use gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf.tar.gz as external toolchain. I am following the steps mentioned in Buildroot manual section 6.1.3. I already have the toolchain tarball so I did not do make sdk part. In the menuconfig I have specified like below:
- Set Toolchain type to External toolchain
- Set Toolchain to Custom toolchain
- Set Toolchain origin to Toolchain to be downloaded and installed
- Set Toolchain URL to file:///path/to/your/sdk/tarball.tar.gz : In my case I have set it to file:////root/br-tcg4/tmp/gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf.tar.gz
Then when I do make I get below errors:
ANSWER
Answered 2022-Feb-02 at 04:52Since it seems that you have already downloaded the custom toolchain tarball, why not simply manually install (i.e. un-archive) the custom toolchain, and then choose the appropriate Buildroot options (i.e. for a Pre-installed toolchain)?
For instance I install toolchains at /opt/, and Linaro toolchains under /opt/linaro/. The same toolchain that you're using is installed on my development PC as:

I'm trying to find a way to isolate a specific paragraph using a string as a starting point, where the string could be a word in any part of the line (not necessarily the end or the beginning).
So it will grab that entire line where the string occurs, and then it will grab until the line where it finds the secondary string. I've checked various questions and I'm not finding quite what I want. Here's an example input paragraph with the desired output paragraph:

I have a C# method that open a HttpWebRequest with an external node module.
Then execute some long DB queries, process those data and send them to the node module.
The node module receive throught a socket, data from c#, and it will turn this data to other data that will be turned back to c#.
For some tests that take ~30min of process, everything went okay. But a bigger test that took around 2hr, I've got the request was aborted the operation has timed out
Here is a part of my code :
...ANSWER
Answered 2021-Oct-02 at 14:47Does the server take 2 hours to respond?
If not, then why don't you get the response immediately and then continue your processing instead of keeping the stream open for 2 hours?
Regardless, in this case, you have set the timeout for the client to infinite, however, the server may be cutting you off due to the lack of the Keep-Alive header.
Try this:
request.KeepAlive = true;
QUESTION
Problem: I am building an app to catalogue holiday leave days. The page I'm currently working on takes 2 dates from the user (start and end date) and then outputs the number of days selected, to be used elsewhere in the app.
Solution: Initially, I wanted to disable the selection of Saturdays and Sundays but the one solution floating around HERE did not work with my solution. My second thought was to instead take the date range the user selected and build an array of those days where I can count the number of Saturdays and Sundays and remove them from the full day total.
Here is the code behind class for the calculator page where I have created the 'removeWeekends' method. I just need some help figuring out how to scan this array for Saturdays and Sundays and then implement that with the page. Any help or advice is appreciated. Please let me know if I can provide more code or elaborate more on my issue.

QUESTION
I read that (soft) real-time programs often avoid heap allocations in part due to unpredictable timings, especially when stop-the-world (STW) garbage collection (GC) is used to free memory. I'm wondering if avoiding heap allocations is at all helpful for reducing lag in a main loop (say, 100 Hz) that uses NumPy and CPython. My questions:
- CPython uses reference counting for the most part and a STW GC for cyclic references. Does that mean the STW part would never trigger if I don't use any objects with cyclic references? For example, scalars and NumPy arrays don't seem to have cyclic references, and most of them would not go beyond the function in which they are allocated.
- Would reducing array allocations (preallocate, in-place, etc) make a significant difference?
- Typical NumPy expressions allocate a temporary array for every operation; what are some good ways to get around this? Only thing that comes to mind now is very tedious Numba rewrites, and even then I'm not sure if non-ufuncs can avoid allocating a temporary array e.g.
output[:] = not_a_ufunc(input)

For example, scalars and NumPy arrays don't seem to have cyclic references, and most of them would not go beyond the function in which they are allocated.
As long as Numpy array contains native scalars (eg. np.float64, np.int32, etc.), it is generally fine. But if the Numpy array contains pure CPython objects, then the GC could be likely an issue (although this is rarely the case since cycles are rare and Python use a generational GC).
Actually, the GC could run a collection in both cases (especially when a new CPython objects are created/deleted, including Numpy arrays). However, the overhead of the GC is negligible with a program using natively-typed Numpy arrays since the number of reference is small (cells of the array are not visible from the garbage collector in this case as opposed to the case where the Numpy array contains pure CPython objects).
Note that reference cycles are theoretically possible with Numpy arrays containing pure CPython objects as two array can contains reference to each other:

How am I doing too much work by simple animation and image is 500x500. How to fix this error?
By the way, it works fine, if i remove animation code Task.WhenAll
ANSWER
Answered 2021-May-30 at 21:14OnAppearing happens just before the page is diplayed.
To get smooth animation, you want the page to finish displaying before the animation starts. This requires the following two code changes:
DO NOT WAIT for the animation to finish - let OnAppearing return.
Delay the start of the animation.
