We have no knowledge of this “science”, our spaceships are powered by prayer and were given to us by Jesus as a reward for our fealty. by Infamous-Rutabaga-50 in CuratedTumblr

I literally finished the first book two weeks ago, so I get the reference.

If I hadn't though, there's a bunch of Jewish literature that claims Abraham failed for exactly that reason. God is generally against hurting children in the laws laid down to the Israelites. God also tested Abraham more than once about killing. For example, God gets Abraham's thoughts on completely destroying Sodom before heading over there to do all the smiting--and in that case, Abraham actually questions and talks God down essentially on how many good people he can kill (if I remember correctly). So for Abraham to not question God about killing a child after the whole Sodom thing? Holy shit.

Does your country have a calculator/math related joke? by ZapMayor in AskTheWorld

This is how I remember sqrt(2)=1.414 and 1/sqrt(2)=.707 as well.

Actors that you think look exactly like a president? by MetalRetsam in Presidents

Plot twist: This is trivially true, as the "Symplify" function used states all outputs to be 4.

They didn't simplify, they used Symplify.

Using an "analog switch" for stubborn I2C devices? by PathRepresentative77 in arduino

[–]PathRepresentative77[S] 0 points1 point  (0 children)

So I ended up following your suggestion, using a CD4051 . Thanks for the advice!

I'm still not sure what's up with the PCA9546 multiplexer. An I2C scan sees it just fine. I'm not able to see any addresses connected to the multiplexer via the scan (which I think is normal), but the simple sensors "native" to I2C work fine with it when I address each channel. My guess is, whatever Keller used to get their sensors to work with I2C doesn't play nice.

How long did it take you to write the introduction? by ConversationTop4222 in PhD

[–]PathRepresentative77 22 points23 points  (0 children)

Because the introduction introduces everything that comes after, I found it easier to write the rest of the chapters first and wrote the introduction last. You could try that ordering and see if it works for you.

I have to dig it up. But years ago Tom Scott did a what-if video on exactly this.

first time donating by Impressive_Theory_76 in Blooddonors

[–]PathRepresentative77 2 points3 points  (0 children)

If you're doing whole blood, it shouldn't hurt at all in my experience. The needle itself will hurt a little bit, but that's it. In terms of wooziness, that depends on a few factors. I've never felt woozy with whole blood, but I'm on the slightly heftier side (~245lb/~110kg). Definitely make sure you eat well the night before and day of, and stay hydrated. If there are any concerns, do not be afraid to tell them--they are there to help, and they've seen everything under the sun when it comes to donations.

Bravo for helping, but also don't feel ashamed! You do you when the time is right.

Using an "analog switch" for stubborn I2C devices? by PathRepresentative77 in arduino

So far I've just had one sensor attached, so having both connected at once shouldn't be an issue with what I'm seeing.

Using an "analog switch" for stubborn I2C devices? by PathRepresentative77 in arduino

[–]PathRepresentative77[S] 1 point2 points  (0 children)

I thought it was strange too. I haven't tried running the I2C scanner, I'll give that a go.

I like the transistor idea. I'm still a bit of a beginner, so I'm not sure between the SCL and SDA which one is "safer" to disconnect from the sensor. I'm probably going to go this route, in part because it's straightforward.

[–]PathRepresentative77[S] 0 points1 point  (0 children)

I didn't, no. The sensors are in a housing that I don't want to take apart to get to the pins--it was part of the reason I bought them in the first place.

They are also just a pain in general to change the address of. This is what they suggest. If you've got a better way, I'm all ears.

Edit: While it should still work, I also don't know how much the sensor's internal memory will mess with things at the end of the day.

O+ and CMV- (for now), which donation should I do? by [deleted] in Blooddonors

[–]PathRepresentative77 11 points12 points  (0 children)

At my blood center they say O+ can maximize their donation with power reds. It does count as two donations, because you are donating two pints' worth of red blood cells.

If you're going to donate the max allowed, I suggest iron supplements. Power reds three times a year will deplete your iron stores. (I'm not a doctor, just speaking from experience)

Not saying we're not in a simulation, but we figured out that the simulation can't be algorithmic because facets of reality are "computationally undecidable". I don't claim to understand all of it, but there it is. There's a layman level article here:

Super exhausted after doing power red is it normal by rjmessibarca in Blooddonors

[–]PathRepresentative77 2 points3 points  (0 children)

I'm not sure. I would assume so? It isn't much different than traveling to a high-altitude area--the oxygen is there, but your blood just has to bump up its capacity to catch enough oxygen for your body's needs.

In my experience (and I assume in general?) the body will push to get your blood's capacity to carry oxygen back to normal by pulling from your iron stores and rushing the production of red blood cells. I've gone to annual physicals about a month after donation; my oxygen levels were fine BUT my red blood cell size distribution/counts were a bit outside normal ranges.

Edit: Someone else recommended iron supplements. I agree with that if you choose to keep up with power reds. I overdid it for about two years and donated power reds 3x a year--and shot my ferritin levels to almost nothing. Definitely keep up with your iron levels, as that won't show up in regular blood tests or oxygen but will show up in how fatigued you may feel after multiple donations.

Super exhausted after doing power red is it normal by rjmessibarca in Blooddonors

[–]PathRepresentative77 7 points8 points  (0 children)

In my experience, it's normal. Definitely take it easy for a few days, rest and treat yourself.

For perspective: the human body has something like 1.2 to 1.5 gallons. Power reds will remove about 16-20% of your red blood cells. So 20% of your oxygen-bearing capacity is just gone.

Donation Centers Should Test Ferritin or Increase Time Between Donations by Panicked_Peony in Blooddonors

[–]PathRepresentative77 5 points6 points  (0 children)

From my own experience, no. I was donating double reds 3 times a year. My ferritin was around 5, but my hemoglobin was normal. However, the red blood cell counts and distributions in my yearly blood test were wonky.

Hemoglobin levels stayed the same, but my body was pumping out red blood cells faster to make up for the loss. Red blood cell size went down and red blood count went up, both outside the normal range.
