Using Emacs as editor for SBCL

Using Emacs as editor for SBCL on Windows 10

Emacs is installed in C:\emacs, using version 30.2. I run it using C:\emacs\bin\runemacs.exe.

SBCL version 2.6.4 (sbcl-2.6.4-x86-64-windows-binary.msi) is installed in C:\Program Files\Steel Bank Common Lisp

1. Install Sly package manager in Emacs

M-x package-refresh-contents
M-x package-install RET sly RET

2. Create or edit ~/.emacs.d/init.el
3. Edit or replace contents like below
4. Restart Emacs
5. Load Sly

M-x sly RET

Note: Verify that you are not using ~/.emacs, otherwise it will not load configration from ~/.emacs.d/init.el Below shows SBCL loaded.

Zig basic Windows application using win32 API

Info:
OS: Windows 10 IoT LTSC 2021
Zig: 0.15.2

Sample application using zigwin32, Windows API to create basic window that does nothing. It calls the following win32 API functions:
- LoadCursorW
- RegisterClassW
- GetLastError
- CreateWindowExW
- ShowWindow
- GetMessageW
- TranslateMessage
- DispatchMessageW
- DefWindowProcw
And windows WindoProc function for pumping messages.

Create a Zig application, like:

PS C:\prj\> mkdir hellowindow
PS C:\prj\> cd hellowindow
PS C:\prj\hellowindow> zig init

Modify build.zig to add zigwin32. See lines 86-91 in gist below. Update src/main.zig to look like below. Checkout zigwin32 into the root of the project

PS C:\prj\hellowindow> git clone https://github.com/marlersoft/zigwin32 libs/zigwin32

Now do a build:

PS C:\prj\hellowindow> zig build

Or do a release build that produces the smallest binary:

PS C:\prj\hellowindow> zig build -Doptimize=ReleaseSmall

Demo how to use zigwin32 in your zig application

Create a Zig application, like:

PS C:\prj\zigwin32test> zig init

Modify build.zig to add zigwin32. See lines 68-72 in gist below. Update src/main.zig to look like below. Checkout zigwin32 into the root of the project

PS C:\prj\zigwin32test> git clone https://github.com/marlersoft/zigwin32 libs/zigwin32

Now do a build:

PS C:\prj\zigwin32test> zig build run

Error opening directory '/media/sf_C_DRIVE': Permission denied

I tried to share a folder from Windows 10 host to Kali 2020.1 Linux guest using VirtualBox but I am getting the following error message:

Error opening directory '/media/sf_C_DRIVE': Permission denied

To fix, do:

$: sudo adduser $USER vboxsf

Then log-off then log back in. If this does not work, reboot the VM

Getting similar issue using Fedora 33 on VirtualBox 7.0.12 (tested up to Fedora 41 [VBox 7.2.4]) , below is the error message

This location could not be displayed You do not have the permissions necessary to view the contents of "sf_D_DRIVE"

To fix do the following and reboot the VM.

$: sudo usermod -a -G vboxsf $USER
