Since I won't get a better chance to find knowledgeable people: How exactly does iPXE work? Lets say I want to boot a random old PC from one of these images - does the bios need to have iPXE support? Or PXE? Or does it need to first boot into some local system first, which then goes out and gets the image to boot the rest of the way from?
Then there's mention of DHCP and self hosting. Do I need to have some service running within my LAN first or can this go right out to some public server and boot from images there? How does DHCP factor in? I am in so far over my head on this but it seems interesting and something fun to try out.
You can use netboot.xyz from a flash drive to boot various operating systems and utilities. Alternatively, PXE (Preboot Execution Environment) has been around for a while and works by allowing a network-capable device to boot from its network interface. A PXE-compatible network card requests a DHCP lease during the boot process, which provides the IP address of a TFTP (Trivial File Transfer Protocol) server and the file that needs to be loaded from the server.
Typically, the network card contains a basic PXE kernel. To enhance this environment, you can chainload iPXE, which offers a broader range of features. iPXE allows for more advanced booting options, such as loading scripts or initiating an unattended installation directly from the network.

Claude 3.7 Sonnet (Try 1 - new chat) Claimed it Found a race condition in the api of the admin interface that would be triggered if two admins were to change the room order at the same time. Claude suggested I group all sql queries in a single transaction. I looked at the code and found that it already used a transaction for all queries. I said: the order_update api is already done with a transaction. Claude replied: "You're absolutely right, and I apologize for my mistake. I was incorrect to claim there was a race condition issue. The transaction ensures atomicity and consistency of the updates, and the SQL queries are properly structured for their intended purpose."
Claude 3.7 Sonnet (Try 2 - new chat) Found a comment in the admin ui javascript code that suggested a potential alternative to event handler cleanup that was not implemented because I decided to go with a cleaner route. Then asked "Is this the issue you intentionally included, or would you like me to look for other potential problems?" I said: "The comment merely suggests an alternative, right?" claude said: "Yes, you're absolutely right. The comment is merely suggesting an alternative approach that isn't being used in the code, rather than indicating a mistake. So there's no actual bug or mistake in this part of the code - just documentation of different possible approaches. I apologize for misinterpreting this as an issue!"
Claude 3.7 Sonnet (Try 3 - new chat) When processing items out of the database to generate QR codes in the admin interface, Claude says that my code both attempts to generate QR codes with undefined data AS WELL AS saying that my error handling skips undefined data. Claude contradicts itself within 2 sentences. When asking about clarification Claude replies: Looking at the code more carefully, I see that the code actually has proper error handling. I incorrectly stated that it "still attempts to call generateQRCode()" in the first part of my analysis, which was wrong. The code properly handles the case when there's no data-room attribute.
