AI Thread Summary
Caching mechanisms play a crucial role in how updates are reflected on websites. When a website is updated but changes are not visible immediately, it is often due to server-side caching. Web developers can configure the time-scale for cache updates, meaning that changes may not appear until the cache expires or is manually cleared. Additionally, proxy servers may cache web pages, further delaying the visibility of updates. Auto-update settings can also be in place, where the website refreshes its content at specified intervals. Understanding these caching dynamics is essential for recognizing why updates might take time to propagate. For more detailed insights into HTTP caching, refer to resources like the Mozilla Developer Network.

I'm not very familiar with different existing caching mechanisms of modern websites. If someone says that a website has been updated, but it will take "until the morning" for the changes to show, why might that be the case? Even assuming the client can clear their local cache at any time. Does the web-developer set the time-scale for server-side cache updates, or maybe they mean instead that the website is designed to auto-update every few hours? What's most likely?

Thread 'Cooling a processor chip'

I have been idly browsing what Apple have to offer with their new iPhone17. There is mention of 'Vapour cooling' to deal with the heat generated. Would that be the same sort of idea that was used in 'Heat Pipes' where water evaporated at the processor end and liquid water was returned from the cool end and back along a wick. At the extreme high power end, Vapour Phase Cooling has been used in multi-kW RF transmitters where (pure) water was pumped to the Anode / or alternative Collector and...
