Lots of things today Gave my presentation on the Windows Receiver spike AKA the Windows Workspace App it went well.. better than expected I managed to pull things together at the last minute and flesh out enough of it in an organized fashion now there's some better direction for each of us to take to make sure we get the best job done with the least amount of waste or something like that in any case.. we need to have a discussion about the figures yesterday obviously I was being a bit lax in the manner in which I was extrapolating numbers that is to say, we expect that the %s of those who go seek covid tests are going to be higher positives than those who are selected randomly but what's interesting is that if yu look at the figures, including the seroprevalence test, we find that the numbers are higher than 50% of the positive detection rates, even as far as back 1.5 months ago that means that, if we have a place where the positive rate is about 6.7 % ( California) and you look at seroprevalence nearly 2 months earlier, we can see that almost 4% tested positive now if you imagine how many more people were infected since then, it must be higher.. it certainly wouldn't have gone down, as only more people can become exposed to it and been able to manifest some antibodies the problem with that situation is that we don't understand whether or not the antibody specs are reliable that is another investigation which has to be undertaken which reminds me, it used to be good to go after very specific information and argumentation, because it forced you to be able to peel through the layers of the subject and understand the relationships between themu until tyou can finally get to a layer which is high resolution and low level enough to be able to find some deterministic or compelling element which is close to fundamental enough to be viable in an actual developed argument those are the types of distinctions we need the focal point where something becomes unmistakable and I believe that, quite often, it just takes a bit of extra gusto in order to make the difference that gets your point across so we need to focus on specific problems some more It's too bad I can't get all of the other colleagues and compatriots involved in a way where we're able to leverage one another's strengths and work most adequately for our own pursuits quite often, everyone has an idea of what someone else means, without being open enough to move together with good intentions, at least for as much time as possible exit what are my thoughts and why am I having them am I just thinking of these words because I am typing, or am I typing while having thoughts, and those thoughts are therefore being typed? it'shard to say what takes precedence or hwo to make the distinction between the two had you not been thinking what you were thinking, while typing what you believed to be that thing that you were thinking, then you would have been thinking something else and that you were typing now, but not typing at the time imagined in your head for comparison, doesn't give any evidence both for or against the notion that you might be having the same thoughts at different times or under different circumstances for the same time exit So you want to ask me some questions about Vaccines do I think they're effective? well yes, the basic premise is sound.. the idea that you wish to perform an action to evoke a modification of your system in this case, you would like the adaptive capabilities of the immune system to be calibrated such as to be able to identify new constructs, in this case viral particles, and be able to ellicit a response which increases your chance of mitigating the threats associated with the presence of those viral particles That is, eliminate or reduce the ability of those viral particles to proliferate. What is a vaccine? A vaccine is something which when administered fulfills the delivery of immunogenic material from a pathogenic microbe to induce protective immunity against a disease exit need to have a conversation about what's going wrong when I try to make progress on the STM32 project that is, the Jordan B Peterson bot project Clean Your Room bot alpha at the moment so the main problem is that I can't get serial communication to work between two boards I am trying to setup USART communication simply by attaching the RX and TX pins of the two boards and sending a single character hoping to trigger an interrupt on the receiving board, or in this case the slave board depending on how you want to reference it it seems that one of the problems might be the whole AFR thing Im' not really sure what it means, because yrou're already configuring the RCC clock to enable USART, so that's essentially providing power to the parts of the board as power oscillates through the circuit that part of the board being the part responsible for USART communication, which I suppose is a set of pins and busses connected within their own circuit an dthat circuit also contains a few other components, such as registers for storing data temporarily as we read, for example, the status the receiving register, the sending register, and so forth there are a few other registers for configuring other aspects of the USART behaviour, such as the parity bit, the baud rate, which has to take into consideration the particular clcok speed of the board. This is relevant because the board is usually running at a speed which will conserve power. SO then the other thing is the AFR register. WTF is it and why do we need it? so it would appear that the AFR register somehow allows Alternate Functions to reach the pins at all and you can set which pins are being allowed a specific alternate function furthermore, you also have to configure the individual pins to be set to alternate function moder MODE it's confusing that you have to do both of htese things.. you would think that you are doing it through the pin itself, but apparently you need to enable the pin through the AFR first then, tyou also need to enable USART on the clock... I guess that's because the data or electricity from that part of the circuit has to make it all the way throughh the entire board, or at least as far as is required for it to get out of the board ? it's strange.. I'm not really sure how much of it I undersstand, but i'll just need to keep plugging away and fgigure out the rest as I go along so to summarize.. I've been abel to figure out how I should be configuring the AFR registers, by verifying what values they are receiving from the HAL usart code, and then adjusting my code if necessary such that it DOESN'T change the value of the register Nevertheless, I've still not had success, and, moreover, I've not seen any sort of evidence which proves that it's possible to get successful serial communication (USART) between two boards.. it almost seems like that's supposed to be the eventual result of trying to work with multiple, but that hasn't proven to be the case yet. exit
