Windows Powershell command to touch all my files in a directory

 Credit to chatGPT:

In Windows 11, you can use a simple PowerShell command to "touch" all your files, updating their timestamps so OneDrive considers them "fresh" without making actual content changes. Here's how you can do it:

Steps to Update File Timestamps

1. Open PowerShell as Administrator:

   • Press Win + X and select Windows Terminal (Admin) or PowerShell (Admin).

2. Navigate to the folder you want to "touch":

   powershell
   cd "C:\Path\To\Your\Folder"
   

3. Run the following command to update the LastWriteTime for all files recursively:

   powershell
   Get-ChildItem -Recurse | ForEach-Object { $_.LastWriteTime = Get-Date }
   

   This will set the LastWriteTime of all files to the current date and time.

---

Explanation:

• Get-ChildItem: Retrieves all files and directories in the folder.
• -Recurse: Processes all subfolders and their contents.
• ForEach-Object: Iterates through each item.
• LastWriteTime: Updates the timestamp to Get-Date (current date and time).

---

Important Notes:

1. Test First: Run this in a small test folder to ensure it behaves as expected.
2. OneDrive Sync: After modifying timestamps, OneDrive should sync the updated metadata and treat the files as fresh.
3. Preserve Original Timestamps: If you want to preserve original timestamps, back them up before running this script.

Emerson Quote

 The quote reads: "To laugh often and much; to win the respect of intelligent people and the affection of children; to earn the appreciation of honest critics and endure the betrayal of false friends; to appreciate beauty; to find the best in others; to leave the world a bit better, whether by a healthy child, a garden patch or a redeemed social condition; to know even one life has breathed easier because you have lived. This is to have succeeded.” [Yahoo news article on Jeff Bezos]

GLSL floats to ints syntax

 welp...don't want to go looking for this again:

    int idx= int(payload.flip);

visual studio BKM and ensuring HLSL files are built after changes are made

 so...you have an .hlsl file and you want to make sure your changes trigger a rebuild do not use the pre-build for the solution. instead, click on the .hlsl and use a custom build tool. the final thing you have to do is to tell visual studio to treat the output as content and fill in the content field with your compilation output artifact(s).

neat sample, needs minor cleanup to compile on my VS2019 solution. may not be anything wrong with the right environment, etc. just my config:

several #include <iostreams>

disabled 'treat errors as warnings'.
