content: So I just got TI's EAP questions (texas instuments asks you about your opinion on a topic). They basically asked me if I'm fine with the technical term, master/slave. This is ridiculous. Some people actually want to change these terms, because, it is "not politically correct". Now, I'm not a redneck (oh no, I should have said country music and NASCAR enthusiast). But someone please explain it to me: Are there anyone, who is actually upset about these terms?What is next? Female connector term will be banned? Or we have to use different term for penetration dept? When did everyone got so bored with their life, that they are actually bothering with this?

I just don't say it out loud...I was messing around with SPI the other day and I had that very thought: When will they have to come up with another pair of names for the master/slave relationship? Boss/worker? We already have reverse gender plugs and receptacles. Male/female pipe threads?

If you have a ADC connected to a microcontroller, the ADC is the server, which is always* ready to transmit information, when the microcontroller requests it. Totally confusing and unnecessary, and reverse to master/slave.

content: with drives this can still be the case. one sata port to another is parallel, they have their own channel. Still in a configuration that term is used (such as in clusters, computer architecture, drives) the master/slave analogy makes the most sense just like with male/female connectors, you know they plug into each other. You cant plug the same gender into the other correctly lol so its an accurate analogy in a way and makes it easier to understand when it comes to looking for what you need.You could use the term primary/secondary instead and with connectors perhaps connector A and B since people are much smarter now but in the past if you said primary drive or secondary to someone in the past they wont understand it so these analogies are used as in the past people werent as smart with technology as they are now. I still would say that people arent as smart with technology now as they think its all magic (theres so much wrong you can explain to almost anyone around and con them.

content: Quote from: Mr.B on September 28, 2016, 11:04:43 pmI've seen it just memorized in order of the rainbow. For example, we start with BLACK, then BROWN as it is a mix between black/red, and then RED is next. So first 3 colors are BLACK, BROWN, RED. Then you have basically the rainbow starting with RED.... ORANGE, YELLOW, GREEN, BLUE, VIOLET. Then from violet you need to get to white on the end, so you have GREY in-between the violet and white, because if you mix violet and white, you get a light purple/greyish color (ok, it's a stretch but that's the only one off). That's easier to me than memorizing a sentence, to be honest.As far as the multipliers go, it is just 10 to the power of the color's number. So BLACK being a 0, so 10 power 0 is 1x. BROWN is 1, so 10 power 1 is 10x, and so on through to BLUE which is 6, or 10 power 6 is 1,000,000x. After that, you memorize gold 0.1 and silver 0.01, and the tolerances BROWN (1%) RED (2%) GOLD (5%) SILVER (10%) (also same order as all the other digits). If no band then 20% tolerance.Not sure if this is harder than the mnemonic.

content: Quote from: edy on September 29, 2016, 05:10:14 amThat's pretty much how I taught myself to remember it: Black, Brown, <rainbow (with the merge of indigo & violet>, Grey, White. Follow with the multipliers. After a few years, you can spot a 4.7k resistor in a pile just by looking at it.QuoteThat took a bit longer. I don't use many values that low.QuoteGold, Silver and none were easy enough - and for so many years that's all I ever came across. The others took a little getting used to.But my biggest beef is with reading colour bands on blue bodies - especially 1% resistors when you're not sure which end is the start.

content: While we are talking about colour codes....One place I worked at went through a file system restructure - getting new shelving, folders and a great array of stickers. These stickers were colour coded - ten colours for numerics and ten colours for groups of letters.BUT - did the colour sequence follow the colour code that had been around for DECADES on electronic components?NO!That was the most frustrating exercise I ever encountered. I had to ignore the colours and simply file according to the alphanumerics. Even then, old habits had me looking at the wrong place all too often.

Indigo dye has been around a *very* long time and in Newton's time people were a little closer to the soil and probably recognised the colour for what it was. Indigo proper comes from the asian plantIndigofera tinctoriabut a chemically identical dye obtained from a different plant was around in ancient Britain as Woad and has been used to dye cloth (and skin) in Britain for thousands of years.

She ended up moving over to a "Christian Web Hosting Company" and paying about 3x as much. That company also used FreeBSD servers!Edit: Funny thing is she used a Mac! She would have really blown a gasket if she realized her email was being sent by Darwin! (Plus Hexley, the Darwin mascot is a platypus with horns and a pitchfork!)
