    Reminds me I have to catalogue 2 Tandem Non-stop! Systems at work… I don’t need to meddle with the cobol code atop but still, this was quite a surprise to stumble upon.

              It's considered a secure method of document transfer over email, despite email being able to be secured and fax can be hacked with like a length of wire and a knife. Fucking irks me.

                Fax operates as data over phone line, similar to dialup. If you can get a wiretap on a phone line, you essentially can get everything that passes over it. Technically you could encrypt it, but it's usually not required you do legally.

                        If you buy a brand new Skyhawk here in the space year 2025, it will come with a newly made Lycoming IO-360 that requires 100LL. I think they're still working on eliminating leaded avgas, I think because the Trump regime hasn't noticed it yet.

                          Steam engines.

                          The vast majority of our power comes from making something really hot and boiling water. Coal plant? Oil plant? Gas plant? Nuclear fission plant? Geothermal plant? The grand holy grail of energy production that would be a nuclear fusion plant? All steam engines.

                          Yes, unbeknownst to everyone, this is what a steampunk society realistically looks like.

                                Radio. I still listen to radio over the airwaves, and received by an antenna, as it has been done since 1920.

                                Bicycles are not much different since around 1900.

                                  Yeah, it's so hilarious to want an engine that will continue to run after a complete electrical system failure at 10000ft.

                                  Fuck 100LL though.

                                    Because how many attackers are actually interested in attacking fax? Like... have you ever heard of hackers hacking physical mail? It's to old for people to care, and "people not caring" is implicitely secure by ignorance.

                                      The Rotax engines use digital CDI ignition that is independent if the airframe electrical system, and from each other. I've never seen one fail.

                                        That can't be the actual name of those, is it?

                                        I've always kinda wondered, and generally call them TRS or something (I'm audio engineering background, American, millennial), so looked it up:

                                        From https://en.m.wikipedia.org/wiki/Phone_connector_(audio) under the "other terms" section:

                                        The 1902 International Library of Technology simply uses jack for the female and plug for the male connector.[3] The 1989 Sound Reinforcement Handbook uses phone jack for the female and phone plug for the male connector.[4] Robert McLeish, who worked at the BBC, uses jack or jack socket for the female and jack plug for the male connector in his 2005 book Radio Production.[5] The American Society of Mechanical Engineers, as of 2007, says the more fixed electrical connector is the jack, while the less fixed connector is the plug, without regard to the gender of the connector contacts.[6] The Institute of Electrical and Electronics Engineers in 1975 also made a standard that was withdrawn in 1997.[7]

                                        The intended application for a phone connector has also resulted in names such as audio jack, headphone jack, stereo plug, microphone jack, aux input, etc. Among audio engineers, the connector may often simply be called a quarter-inch to distinguish it from XLR, another frequently used audio connector. These naming variations are also used for the 3.5 mm connectors, which have been called mini-phone, mini-stereo, mini jack, etc.

                                        RCA connectors are differently shaped, but confusingly are similarly named as phono plugs and phono jacks (or in the UK, phono sockets). 3.5 mm connectors are sometimes—counter to the connector manufacturers' nomenclature[8]—referred to as mini phonos.[9]

                                        Confusion also arises because phone jack and phone plug may sometimes refer to the RJ11 and various older telephone sockets and plugs that connect wired telephones to wall outlets.

                                        Yeah, these days I just call them 3.5mm audio plug, or quarter inch audio plug.

                                          Fax machines will never die no matter how they are mocked. It simply is the easiest way to send documents with private information and it's fast. At least we have e-faxing now to receive documents.
