    From john larkin @21:1/5 to All on Sat Jul 27 10:42:17 2024
    I'm planning a new product line, some little PoE instruments, using
    the dual-core Raspberry Pi RP2040 chip. One CPU will do the
    communications, math, calibrations, and such, and the other will be
    hard bare-metal realtime I/O.

    We were debating what to call the two CPUs. Left and Right? Manager
    and Realtime? Alice and Bob?

    https://en.wikipedia.org/wiki/Alice_and_Bob

    Can't say Master and Slave any more.

    We did some timing tests on the 2040 chip. It's awesome, for 70 cents.

    "master and slave" were never particularly descriptive terms, anyway.
    "Master" seems pretty obvious and probably translates to most languages
    but what does a "slave" do? Always do the work the master says? As conservatives are fond of saying there were lots of types of slavery
    throughout history it wasn't all whips and cotton-picking.

    I think engineering should really use engineering terms, not
    anthropomorphic analogies when it can. I don't like a lot of the
    alternatives better though sometimes primary/secondary or
    leader/follower doesn't make sense, either.

    But while being somewhat vague I think "Master" in isolation is ok, if
    one is doing the complex operations and one is optimized for realtime
    speed why not "Master/Blaster"? Sounds cool, unlikely to offend anyone
    except people who don't like Mad Max movies.

    MasterBlaster ain't bad.

    I accidentally found some people who overclock the RP2040 chip, past
    its 133 MHz spec. Seems like 420 MHz just works. Some maniac froze one
    and got it to run at 1 GHz.

    I just worked on some gas sensor code
    gas_pic_udp_tx
    gas_pic_udp_rx

    the tx sends the gas concentration with POE over ethernet
    to a Pi4 that runs gas_pic_udp_rx

    If anything is wrong the rx will tell you about it (voice from raspi via audio amplifier,
    normally it plays background music or is silent).
    In my case the tx is just a Microchip PIC with my own UDP stack.

    As there are so many things running here, just use names that make sense.
    ...tx and ...rx as to what to does (sent data or receive data).

    As to master and slave, are our gut bacteria our slaves?
    Or are we the slaves that feed them and they the master?

    What was the word? Ah:
    symbiosis, any of several living arrangements between members of two different species,
    including mutualism, commensalism, and parasitism.
    Both positive (beneficial) and negative (unfavourable to harmful) associations are therefore included,
    and the members are called symbionts.

    Nature, master slave almost reminds me of school times
    Master tells you what to do and slaves make the homework?

    TX and RX are ambiguous. One box's TX is the other guy's RX.

    When I did supervisory controls and building automation, I used "poll"

    I think the fundamental characteristic of "slavery" is that one person
    is the property of another, not one who does what's requested which is
    more like leader/follower.

    What does it mean for one processor to be "property" of another? Doesn't
    make sense.

    Exactly. It shouldn't be hard to assign names to devices that convey their respective FUNCTIONALITIES.

    I've 280 CPUs in my prototype (let's not count cores). *NONE* are "master"; does that make them all "slaves"? (or, "freeborn"? :> )

    You assign names to devices as an aid to describing their roles in the
    design -- so others can make educated deductions about the devices/components of which you speak: RDBMS, environmental monitor, PSTN i/f, PLC modem, etc.

    These days the Dutch government makes apologies for slavery' in the past.
    But these days millions from those places in Africa try anything to get here because the situation is so bad in Africa.

    So maybe those slave complainers should actually be grateful their ancestors were 'enslaved'
    so they could grow up here with enough food and good living conditions.
    Many of those that did not get 'enslaved' (left behind) obviously failed.

    US can print a million dollar for each citizen, those can then buy things cheap from China
    no need to work, but you can if you want.

    Better and simpler than making war everywhere to sell weapons like US does now. Or AI may put some humans in their zoos and discard the rest

    Actually, "Master Blaster" was the original name for the arcade piece that was eventually renamed "Blaster". It predated the Mad Max reference by two or three years.

    Actually, "Master Blaster" was the original name for the arcade piece
    that was
    eventually renamed "Blaster".  It predated the Mad Max reference by two or three years.

    [Not to be confused with "Blaster Master" released many years later]

    the tx sends the gas concentration with POE over ethernet

    TX and RX are ambiguous. One box's TX is the other guy's RX.

    When I did supervisory controls and building automation, I used "poll"
    for commands sent from the central computer, and "reply" back from
    remote gadgets.

    Not necessarily. It's about which end is in control, not the

    And there is nothing inherent in either "end" to suggest where
    control *need* lie.

    The producer could take it upon itself to deliver to the consumer
    just as easily as the consumer could *command* the producer to
    make such deliveries.

    Who initiated the activity is likely of less importance than the actual function being performed when it comes to understanding the design's architecture.

    As to that US debt:

    US national debt tops $35 trillion:
    https://www.rt.com/news/601810-us-national-debt-milestone/
    According to the House Budget Committee’s calculations,
    the debt now equates to $104,497 per person, $266,275 per household and
    an eye watering $483,889 per American child.
    Over the past 12 months, the debt increased by $2.35 trillion,
    with the rate of increase equating to $74,401 in new debt per second.

    Its all over now for the US

    We were debating what to call the two CPUs. Left and Right? Manager

    Can't say Master and Slave any more.

    Leader and Follower ... Fuhrer and Sheeple?

    Trump and Vance?

    I like that one !

    Good luck having the whole electronics industry change from
    Master/Slave to something else. I mean, look at the references in the
