Since we are all concerned with php2shell patch, let me share the fact that, like bugs, "patch for software" is also not a metaphor.

You know that ancient computers ran on punched paper tape and cards with one hole per bit of instruction.

If the code had an error, programmers had to physically cut out the flawed section, cover the hole pattern with a scrap of paper, and re-punch the correct code onto it.

This patched piece of paper is where the term "software patch" originates.

We still apply patches, just not on paper but hundreds or perhaps thousands of endpoints.

DigitalOcean has quietly ended its free hosting program for open source projects... just a month after donating $3 million to Omarchy Linux.

If they had millions to donate to one project, could they not have chosen to (continue to) support hundreds of open source projects?

And no, I am not blaming Omarchy here in anyway.

Finally...Ubuntu has redesigned its Wiki.

Not only does it look good, it is also well organized for anyone who wants Ubuntu related information.

One of the features that many people may miss is accessing the wiki via MCP.

Add the MCP server to your (local) AI setup and your agent gets more accurate information on Ubuntu when needed.
