Article summary

The article discusses a domain name 'valve.computer' and its potential value, but the discussion quickly turns to the topic of thermionic valves and their use in old computers. The conversation revolves around the differences between 'cold boot' and 'warm boot' in the context of tube hardware. The article itself appears to be about the domain name, but the comments delve into the technical aspects of thermionic valves. The discussion includes various anecdotes and technical explanations about the use of thermionic valves in computing.

Main themes

  • Thermionic valves
  • Cold boot vs warm boot
  • Vintage computing
  • Domain names
  • Technical nostalgia

What commenters say

  • The terms 'cold boot' and 'warm boot' originated from the need to wait for thermionic valves to heat up before use, but their meaning has changed over time to refer to different types of system restarts.
  • The heat generated by thermionic valves is not just a waste byproduct, but is actually necessary for the electrons to move between the electrodes, making them functional.
  • Some commenters argue that the current required for the thermionic effect is not just about the heat, but also about the electric potential between the electrodes, and that lowering the current requirement is possible through thermal insulation.
  • The use of thermionic valves in modern projects is seen as a fascinating and inspiring endeavor, with some commenters appreciating the technical challenges and nostalgia involved.
  • There is disagreement about the historical origins of the terms 'cold boot' and 'warm boot', with some arguing that they have been used in computing since the 1950s, while others claim they originated later.
  • The efficiency and power requirements of thermionic valves are discussed, with some commenters suggesting that they can be made more efficient through creative circuit design and thermal insulation.
