            How to Config Javascript ' script in Django?

            I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.

            Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS is the same as TEMPLATE to config django.core.context_processors.static but when I paste that code, turns in error saying django.core.context_processors.static doesn't exist.

            I don't have idea why my javascript' script isn't working.

            Run ‘python manage.py collectstatic’ and try again.

            The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.

            Seems like you already have the part where you are extracting the attachments. Try this code to retrieve the body of a multipart email.

            You may have to figure out how to merge your part with this one.

            QUESTION

            Using std::atomic with futex system call
            Asked 2021-Jun-15 at 20:48

            In C++20, we got the capability to sleep on atomic variables, waiting for their value to change. We do so by using the std::atomic::wait method.

            Unfortunately, while wait has been standardized, wait_for and wait_until are not. Meaning that we cannot sleep on an atomic variable with a timeout.

            Sleeping on an atomic variable is anyway implemented behind the scenes with WaitOnAddress on Windows and the futex system call on Linux.

            Working around the above problem (no way to sleep on an atomic variable with a timeout), I could pass the memory address of an std::atomic to WaitOnAddress on Windows and it will (kinda) work with no UB, as the function gets void* as a parameter, and it's valid to cast std::atomic to void*

            On Linux, it is unclear whether it's ok to mix std::atomic with futex. futex gets either a uint32_t* or a int32_t* (depending which manual you read), and casting std::atomic to u/int* is UB. On the other hand, the manual says

            The uaddr argument points to the futex word. On all platforms, futexes are four-byte integers that must be aligned on a four- byte boundary. The operation to perform on the futex is specified in the futex_op argument; val is a value whose meaning and purpose depends on futex_op.

            Hinting that alignas(4) std::atomic should work, and it doesn't matter which integer type is it is as long as the type has the size of 4 bytes and the alignment of 4.

            Also, I have seen many places where this trick of combining atomics and futexes is implemented, including boost and TBB.

            So what is the best way to sleep on an atomic variable with a timeout in a non UB way? Do we have to implement our own atomic class with OS primitives to achieve it correctly?

            (Solutions like mixing atomics and condition variables exist, but sub-optimal)

            You shouldn't necessarily have to implement a full custom atomic API, it should actually be safe to simply pull out a pointer to the underlying data from the atomic and pass it to the system.

            Since std::atomic does not offer some equivalent of native_handle like other synchronization primitives offer, you're going to be stuck doing some implementation-specific hacks to try to get it to interface with the native API.

            For the most part, it's reasonably safe to assume that first member of these types in implementations will be the same as the T type -- at least for integral values [1]. This is an assurance that will make it possible to extract out this value.

            ... and casting std::atomic to u/int* is UB

            This isn't actually the case.

            std::atomic is guaranteed by the standard to be Standard-Layout Type. One helpful but often esoteric properties of standard layout types is that it is safe to reinterpret_cast a T to a value or reference of the first sub-object (e.g. the first member of the std::atomic).

            As long as we can guarantee that the std::atomic contains only the u/int as a member (or at least, as its first member), then it's completely safe to extract out the type in this manner:

            os.mkdir() creates a directory, wheras os.mknod() creates a new filesystem node (file), so you should change the applicable function calls to that.

            Alternatively, (due to os.mknod() not being great cross-platform), you can open a file for writing then immediately close it again, thus creating a blank file:

            In the first place you are probably getting an AttributeError error that append is not known. Because you try to append your text to the TextIOwrapper (feeds speeds). You have to use the write method to append the text to the file content.

            Also note that your file is read and written from the current directory, so ./feedsspeeds.txt. As long as you are not executing this script from you Desktop folder, the file will also not be written there.

            Since your XML is relatively flat, consider a list/dictionary comprehension to retrieve all child elements and attrib dictionary. From there, call pd.concat once outside the loop. Below runs a dictionary merge (Python 3.5+).
