--- Quote from: retrolefty on June 21, 2020, 05:43:57 pm --- My memory of the RS232 standard ( DTR, RTS, CTS, etc) was an ATT definition dating from the 1960s, IBM had nothing to do with it. --- End quote --- DCE/DTE classification and related naming in wiring has nothing to do with RS232, which is just an electrical signalling specification, though. See https://en.wikipedia.org/wiki/Data_terminal_equipment for more information, there is no source cited on that IBM claim though. D25 or D9 connector based DCE/DTE was a "complete" system so that the connector gender specified which one is DTE, which one DCE. The complexity of such historical reliefs of course only shows how irrelevant the internal naming of such IBM (or otherwise) system when deciding how to label things in modern designs containing UART interfaces. |

--- Quote from: EEVblog on June 21, 2020, 02:25:14 am ---Adafruit are replacing Master/Slave and other terms in all their documentation: https://www.adafruit.com/blacklivesmatter --- End quote --- Cool! I guess now we get to see if any of the ridiculous slippery slopes that certain conservatives have been yelling about this topic actually come true.... My guess is, they won't. I'm still unsure of how much of a push there is from actual people of colour for this change, and therefore how much a of a need for it there is - but since it's so easy to do, and has some precedent in the community now, anything I have a say in from now on will not use master/slave terminology. I'm warming to controller/peripheral. CIPO, PICO. done. |

--- Quote from: wilfred on June 21, 2020, 08:28:40 am ---I read this today. It might have relevance to some interested in this thread. For those willing to engage in some self discovery there is a link in there to some tests you can do to reveal your own implicit biases. You will find you're not special after all. And I don't mean "special". https://www.pbs.org/newshour/nation/making-people-aware-of-their-implicit-biases-doesnt-usually-change-minds-but-heres-what-does-work --- End quote --- Did you notice Anthony Greenwald, the leading implicit bias expert, says that the only long-term solution is essentially to ignore what groups the applicant belongs to (gender, race, culture), and instead only look at their output? That he's "very sceptical" about "implicit bias training"? That's exactly what I've been saying we should do: treat each others as individuals, evaluate others based on their actions and interactions with others, and keep stuff like gender, skin color, race, "oppressed group" as not-work-relevant personal attributes only. You know, equality of opportunity, and to hell with equity/equality of outcome. --- Quote from: EEVblog on June 21, 2020, 10:36:52 am --- --- Quote from: Nominal Animal on June 21, 2020, 07:18:36 am --- --- Quote from: EEVblog on June 21, 2020, 06:55:10 am ---have even thought about running as an independent myself so I can vote for myself ;D --- End quote --- I'd hate for someone like me getting real political power; they'd be a straight up dick-tator. :-[ --- End quote --- When there was talk about us becoming a republic, one of the names put forward for president was Dick Smith. He famously said he'd only do it if he could be a dictator, as it's the only way to get things done! --- End quote --- Exactly. :-+ I can't help but try and fix problems, and I'm not above manipulating people if I think it is for their own good. |
