QUESTION
I'm implementing a small system in C for a microcontroller. That system has multiple sensors. Inspired by Linux kernel I would like to create sensors-core module and separated sensors for each type of sensor.
When implementing a new module in kernel, there's a macro module_init
. That macro takes a pointer of a structure and stores it in the predefined memory section. At the kernel start, all init functions from all modules are called, one by one, based on that memory section with function pointers.
I'm trying to do something similar with my sensors and sensor-core modules. Let's say my sensors-core module has an array of pointers. Each sensor creates its own configuration structure. I would like to write a macro which would copy pointer of such structure and place it in the array in sensors-core module - all at the compilation time.
sensors-core.h:
...ANSWER
Answered 2022-Jan-03 at 09:21Kernel is not a uC. module_init
takes a function, not a struct, and it might be a good idea to rewrite your interface for that. Kernel loads a specially prepared file and parses it and from it finds the proper function to call.
How can I write such macro?
Put a pointer to the variable inside a section.

QUESTION
I wrote a font parser and renderer based on some functionality in the freetype library, but it currently only works for font files that I specify. I'd like to be able to retrieve fonts from the Windows Font Mapper and then parse and render them, but I can't figure out how to get the actual font data from a logical font.
I thought that the easy way to accomplish this would be to get the font file name from the logical font, but based on other stack overflow posts, there isn't any good solution to this because there isn't a 1 to 1 mapping of physical fonts to the logical font you specify.
This code shows how I'm currently retrieving a handle to a logical font:
...ANSWER
Answered 2021-Mar-10 at 08:14I don't understand why it's getting the exact same amount of bytes as the file, but the data isn't the same.
From the official sample, I found the correct way to use GetFontData.
This is the modified code, and the returned data is the same as fontFileData
.

Sizing the pseudo-element will allow you to set a negative text-indent on the first th to align it to the far left

QUESTION
I've ran into this weird but simple problem. I'm looping through project.systems, each system can be edited via modal form which is included in partial named "_editSystem"
...ANSWER
Answered 2021-Feb-07 at 17:09I don't think you are doing anything wrong.
Without digging deep into the Handlebars source, I think it is safe to assume that a partial does not have access to the same context stack as the template that called it. This assumption is reinforced by the fact that the Handlebars documentation for Partial Parameters states that such parameters are "particularly useful for exposing data from parent contexts to the partial".
So it seems you will need to pass your project ID value to your partial as a parameter, as in:
{{> _editSystem projectId=../project._id}}
Your partial would then reference the projectId
parameter:
{{projectId}}/{{_id}}/edit-system
I have created a fiddle for your reference.
QUESTION
I am trying to use multipass to spawn a build environment, the source code being on the host machine. The idea is that I would mount the source code from the host into the VM and then run the build from inside the VM. (multipass mount src ubuntu:/home/ubuntu/src
).
What I am trying to build is a relatively large c++ project with lots of include files. The build system is CMake + ninja and clang 8.0.
The problem is that the build fails with "file not found" errors for various headers. Each time the "missing" file is different. I say "missing" because the files are all actually there.
This seemed exactly the same as Intermittent, random 'file not found' errors under Windows Subsystem for Linux (WSL), but using the suggested workaround did not help (e.g. I tried setting -j1 in ninja).
Any idea of what could be causing this and if there is a workaround?
My host machine is a macOS Catalina and the multipass VM instance is a Ubuntu 20.10. multipass itself is 1.5.0.
...ANSWER
Answered 2021-Feb-05 at 19:03I ended up opening a PR to the multipass team. After some debugging, we uncovered two problems:
- macOS Catalina has a default
maxfiles
limit of 256, which can be hit when compiling large projects. - There is a limit in
libssh
, which is used by multipass to do the mounts.
To workaround this, you need to:
- Increase the
maxfiles
limit in macOS by e.g. following this - Manually mount the folder by (1) installing
osxfuse
in macOS, (2) Enable Remote login in Settings -> Sharing and (3) in the VM
QUESTION
My computer crashed and I had to reinstall my system today. I'm running Windows 10 with VS Code and I'm using Debian (WSL) as my main terminal.
I have installed VS Code with the "Add to PATH" option and I have activated the Windows Subsystem for Linux in PowerShell.
I can use the command "code" in CMD and PowerShell but when I try to run it in Debian I get
"-bash: code: command not found"
, as far as I understand it should work straight away when installing with the "path" option? At least according to this article: https://dev.to/ajeet/the-ultimate-guide-to-use-vs-code-with-windows-subsystem-for-linux-wsl-51hc
I have also tried installing the "Remote Development" extension, but I'm still facing the same problem.

Answered 2020-Nov-24 at 14:09Try adding the following line in the .bashrc in your $HOME directory ~/.bashrc. PATH=$PATH:/mnt/c/Users/$USER/AppData/Local/Programs/Microsoft\ VS\ Code/bin
Where you replace $USER with your Windows username.

QUESTION
The topic is about system fonts. what is the purpose of setting button {font:caption;}
? system-fonts
ANSWER
Answered 2020-Oct-24 at 08:12The question asks what is the purpose of setting button {font:caption;}
The system the user is on (normally a browser like Chrome or Safari together with their device's operating system and related storage) will itself have styles for various different items.
In this case the question is about 'caption' - when used as font:caption
as above it is saying to the browser when you see a button element in my HTML please use the same font that you would use to show a button.
This means you can have a website which blends in with the look that the user is used to - buttons (and other things depending on what else you set) will look the same as system ones - in this case at least as far as the font goes.
See https://developer.mozilla.org/en-US/docs/Web/CSS/font for information on what other in-built system formatting can be used.
