Hackery | NET runtime do stuff | Reflection library

I am more of a Java programmer and still somewhat new to development (2 years or so, can write Java code & web apps just fine) however the company I work for has 4 Rails applications and was asked to get this application working called CtrlPanel. I have been having to learn Ruby on Rails in order to help get this issue with this app fixed and get it working.

I have been working on this problem for over a week all day long every day and nothing I do is fixing it.

I fixed everything to the point the app comes up, web server runs serves the pages but all views are white screens as long as this application.html.haml file is present. I re-wrote the file with very basic bootstrap and it sort of works but nothing looks right. The problem seems to stem from 1 single like that simply says: = javascript_include_tag "application"

I have been all over the internet and have tried every single fix from changing coffee-script-source to v1.8.0 as I read Windows has an issue with newer rails and that file, I have tried every variation of changing it from application to default, and every type of ending you can think of no matter what I do it gives me this error message which I can not seem to find.

I am not even sure WHAT that line does, I assume it has to do with the new Google Maps API and I verified the key is valid and it was working before.

This is the error is it giving it says the line with "= javascript_include_tag" "application" giving error ExecJS::RuntimeError at / SyntaxError: [stdin]:1:1: unexpected //=

I am running a PC on Windows 10 20H2 x64 UEFI ruby 2.7.2p137 (2020-10-01 revision 5445e04352) [x64-mingw32] Rails 6.1.3

(I did also install Ubuntu on another machine and it gives the exact same error, also gives the same error on another Windows machine)

The app is working IF I delete the "application.html.haml" file and put in a skeleton basic version all of the other views start working but of course none of them look right no menus no bootstrap no nothing.
Here is the application.html.haml file.

In order to nicely fix https://github.com/ned14/outcome/issues/244#issuecomment-774181015, I want to know if it is possible to detect whether a token sequence is present within a C preprocessor macro argument?

C++11 introduced std::begin(std::valarray&) as well as std::end(std::valarray&).

C++17 introduced std::data() which works with std::vector, std::array, C-style arrays, etc. But why wasn't an overloaded std::data() introduced for std::valarray?

std::valarray is specified to have contiguous storage, which can be accessed by taking the address of a[0] (see Notes).

std::data(std::valarray& a) could have simply been defined to return &(a[0]). Why hasn't this been done? Is it an oversight?

My motivation is that I'm working on a general-purpose serialization library. When it receives contiguous binary number arrays from a source (such as CBOR), it detects if the destination container has an overloaded data(container) function, a container.resize(n) member function, as well as an appropriate value_type (matching primitive number type). The existence of all three makes it possible to efficiently memcpy() the source data directly into the destination container. It would make my life simpler if there was a std::data(std::valarray&) overload. The lack of it isn't a showstopper, but it does make the code more messy.

ADDENDUM: The reason why I want to detect a data function is that it tells me that the destination container is contiguous. If it's contiguous, then I can do an efficient byte copy (via std::memcpy or std::copy doesn't really matter). If it's not contiguous, then I have to unpack each unaligned source array number one at a time and append it to the destination container using push_back, emplace, etc depending on the container type.

ADDENDUM 2: I've decided to use an adaptor and traits approach instead of detecting the presence of a data function. This will make it easier to support non-standard or user-defined container types. My question about why there is no std::data(std::valarray& a) still stands.

ADDENDUM 3: I should have clarified that I need to do this hackery for CBOR typed arrays, which can only be numbers. Furthermore, the numbers in the source buffer are not aligned to element boundaries. I'm aware that the binary data may need endian swapping, and that copying bytes to a floating point type may trigger weird NaN behavior if not treated carefully.

I now regret mentioning my motivation, and should have let the std::data(std::valarray& a) question stand on its own. What a trainwreck this question has become, haha. :-)

It took me some time to pin down the problem. Here is is:

I'm using a proprietary Real-Time OS, and occasionally I need to install and build that OS's kernel from sources (usually for debugging weird kernel interactions). This code is secret, and I'm under contractual obligations to prevent it's release. I'd like to be able to commit the code to a local branch but mark that commit (or possibly that branch) in such a way that I'd have to do something out of the ordinary to push, merge, or cherry-pick it.

Essentially I'm looking for a way to mark a specific commit as a poison pill: once it's added to a branch that branch will no longer push to a remote without special efforts. Is this possible? It seems a common enough use case ("here's my personal debug hackery...boy would it be embarrassing if I pushed that mess") that someone might have implemented such a behavior.

I have a Python module that is built around a native extension written in C. This extension includes code generated using the GNU Bison and (not GNU) Flex tools. That means the build process for my C extension involves calling these tools and then including their outputs (C source files) in the extension sources.

To get this to work when calling python setup.py install, I extended the setuptools.command.build_ext class to call both Flex and Bison and then add the generated source to the Extension source before calling the super class run method.

This means my setup.py looks like:

I saw a lot of similar questions here, but nothing of provided advises has helped. Every time I run cap production deploy I got error:

I am using Rails and the ransacker gem (2.3.2) to build out a table filterable by column name. I want to filter an account based on the first member of that account's email address. The models and instance method look like this:

Versions: Django 3.0.6, Python 3.8, MySQL 8.0, django_filters 2.3.0

Please bear with me as I am not sure if I have entitled the question properly. I will start with the relevant code:
