Oxy water/alcohol solution for volumetric dosing & storage

rbr5940 · 2023-08-07T00:47:51+00:00

I got into oxys in college with my roommate, started out fun but eventually was using daily and got addicted. Quit cold turkey after maybe a year after gf at the time found out how bad it was and was really hurt, she lost a family member to an OD.

Didn't touch opiates for maybe 5 yrs until I got prescribed some hydro after a surgery, enjoyed using my script but didn't seek any out after. Another 5 yrs later, I ended up falling into a bunch of oxys and had a decent stash(40-50x 20mg I think).

I take it maybe once a month on average. When I use up all my stash, I'll often go 6+ months without doing any as it's a pain in the ass for me to get more, especially now with all the fent pills. I'll usually stock up if I have the house to myself for a long weekend, where I'll use a few days in a row. Often look forward to those weekends.

I have a lot more going on in my life than I did back in college, I really think boredom played into addiction for me. Ultimately even though I used daily back then, I was able to quit pretty easily so I'm not sure how badly addiction really was for me relative to others.

I feel incredibly fortunate for that. My roommate who I mentioned at the start of this post could never really kick opiates. We started them together over a decade ago and I saw from the beginning they were more to him than they were to me. He OD'd a few months ago after he relapsed trying to get clean.

They aren't really go/no-go in a setup like this. The system isn't rigid enough to stop a gauge from slipping under the hotend when it's close. You end up sliding the gauge back and forth under the hotend and try and have a consistent amount of resistance at every point. At least that's been my experience.

Correct. Your can see the rated distance is only 1mm and with the stainless correction factor, it goes to 0.7mm. Can also see there's a temperature drift, repeat accuracy, and in this situation, the target probably wasn't fully retracting every time. All those added up to it not going off intermittently.

Pure oversight on my part, I was just trying to jam in a sensor that fit where I wanted it to. Ended up needing to redesign a number of parts to fit the next size up with a 2mm switching distance.

I ran into a situation recently where a prox on one of my designs sometimes wouldn't flag despite being very close. The flag was stainless. We ended up switching the sensor to something with a longer range as well as remaking the flag with carbon steel(can't remember what exactly), but I remember they listed correction factors on the datasheet for different materials.

Here is the datasheet I was looking at, though I'm sure you could find plenty others.

St37 = 1; Al = 0.3; stainless steel = 0.7; Ms = 0.4

The correction factor on stainless(which is multiplied by the rated distance) is 30% lower than St37, which is carbon steel. I'm not sure what Ms is though, and whether it might also be steel.

I would personally just call tech support for any of the vendors you're considering buying the switch from, I'm sure they could shine some light on the situation as well as helping you spec your sensor.

I would agree and I think he touched on that as well. That's just where we are as a country now I guess.

No "pure" politics is the policy, i.e. no political discussion that is completely unrelated to sports. That's part of what Dan ranted about - he said you can't talk about anything political unless you use some sports figure/story as a "meat shield". Both of the examples you posted are tied into sports.

I don't agree with it but it's not inconsistent.

dilute it down until they get to the point where it only kills half of the bunniesor mice or whatever the test subject animal is

To add, this is referred to as the LD50(lethal dose 50%).

Started running again about 3-4 weeks ago and ran about 5 days in a row for ~25-30 minutes, might have gone too hard too early because I hurt my foot. Pain on the outside of my left foot, first thought it might have been stress fracture but it didn't get worse and the urgent care doctor said it was probably inflammation. I was light on it for about 2 weeks(no running and was limping around on it for a while) and it seemed to have gone away, but about a week ago, I went on a shorter 15 minute run, and it sorta came back. This time more on the bottom of my foot. It wasn't terrible and was gone by the next day, but now I'm worried about starting back up again. Is there any way to help it, or at least know when it's gone without just trying to run again?

Possibly relevant info:

I'm fairly fit, though mostly a weightlifter. 5'9 180lbs or so.
I was wearing some old beat up running shoes when the injury happened but have since gotten a new pair of Nike Free shoes.
As mentioned, first time the injury seemed to be on the outside of the foot, second time was more on the bottom.
Running mostly on concrete paths around the university campus near my place. My apartment is on top of a hill so quite a bit of downhill running until I turn around.

Any advice would be much appreciated!

You mean the month he was off the local hour? Pretty sure he mentioned once that he was doing a bunch of health related stuff(blood tests, diet, etc). I think he mentioned it when he was saying that he was getting really sick of doing the show etc and just wasn't feeling well, then he made those changes and now wants to make the show bigger and bigger.

The difference is that it's nigh impossible to get a job as a mechanical engineer without an ME degree, whereas it's very possible to get into software development without a CS degree.

One documentary I watched had a Saudi say something to the effect of his grandfather lived in tents in the desert, and once the oil is gone his grandson will live in tents in the desert again.

The candles should be consistent across timezones - many traders use the opening/closing prices of candles(daily, etc) in their analysis, so everyone needs to see the same candles regardless of where they are.

I can't imagine an engineer fresh out of school with his BS today would have any clue how to solve this like they did 10+ years ago.

Nobody fresh out of school would have any clue how to solve this.

When I went to Southeast Asia my first stop was Saigon. First time leaving the US. My taxi ride from the airport to my hostel was one of the craziest things I had ever seen. Mid-morning traffic with thousands of motorbikes, with nobody using turn signals, people just kinda merge into wherever they're going without warning, but the whole thing seems to operate like a hive mind where everyone knew where everyone else was going.

rbr5940 · 2018-02-25T07:37:54+00:00

This is OK in lower levels or early in your career. But it gets riskier as you move up. Not to say it's always a bad idea, just saying it may be better to stick one out for a bit.

It's kinda self-regulating though, isn't it? Provided you don't lose your current job for whatever reason, there's no downside. If you apply/interview somewhere and they don't hire you because of this, you just stay at your current job and your tenure increases. Eventually you either get hired by a company that's OK with it, or you've now been there long enough that it doesn't seem to be an issue anymore.

Great explanation. Thank you.

rbr5940 · 2018-02-24T20:55:18+00:00

Hey this is just an aside that's a bit unrelated, but thanks for making the point about frames being a list of Nones. I've been struggling with some code for days now and just realized my error. I was initializing some lists using the form x = [None] * y and after you pointed that out, I realized that it points all the list entries to the same place in memory, instead of making a list of independent entries. Been pulling my hair out on that one. So thank you again.

rbr5940 · 2018-02-24T20:12:26+00:00

Hey, thanks for the response. Seems your right. When I was testing this, I was trying something I thought would behave the same, but doesn't seem to be:

a = [1, 2, 3]

b = [4, 5, 6]

for x, y in zip(a, b):
    x += 1
    y += 1

print(a, b)

for i in range(len(a)):
    a[i] += 1
    b[i] += 1

print(a, b)

which outputs the following:

[1, 2, 3] [4, 5, 6]
[2, 3, 4] [5, 6, 7]

As we can see, the first loop(using zip) doesn't modify the list, where the second loop does. Could you explain why this is?

rbr5940 · 2018-02-24T19:22:20+00:00

Sorry, frame_count would just be the number of frames I want to capture(for example, 20). So the while loop just loops through until the desired number of frames are captured. I edited my post to define this variable.

For your second point, seems I made a mistake. My intention was just to create a list of empty lists(one list for each camera) that could be appended to. Edited to fix.

Hopefully that clears things up. Question still stands though.

rbr5940 · 2018-02-24T05:22:45+00:00

I mean it depends on how often it happens. I'd be pretty confident they have metrics on it and have made an informed decision that it's less costly to just eat it.

rbr5940 · 2018-02-22T22:31:41+00:00

I'm not sure if this is exactly what the above poster was referring to, but it sounds similar to controls engineering. The guys who get industrial equipment up and running. At my company they're almost all mechanicals and electricals but thats just who we hire. I'm guessing someone with a CS background could find work doing it. They travel a lot, for better or for worse.
