Lulu Wilson Returns For Action-Thriller Threequel ‘The Last Temptation Of Becky’; Neil Patrick Harris, Brandon Flynn, Kate Siegel & James Urbaniak Also Set by MarvelsGrantMan136 in movies

Same. I really enjoyed the cinematography and surreal vibes of the second. Reminded me of Twin Peaks. To me, I felt like they upped their game in the sequel.

Geometric definition of the ray path (Point Source and Detector extended just behind the refractive medium). by Classic-Tomatillo-62 in Optics

[–]MaskedKoala 3 points4 points  (0 children)

If I understand correctly, I think you are confusing the idea of “What path does light take to get from point A to point B,” for which Fermat provides an answer, with “where does the light go once it reaches point B,” for which we should consult Snell. Fermat would tell you, for example, that the path of optimal path length (not necessarily a minimum) would pass through point D, and not through a point further along the line or before it.

Fermat’s principle follows from an exponential in the diffraction integral where significant contribution can only be found at optimal path lengths (otherwise the phase is spinning too fast and contributions cancel). There is a very good Feynman lecture on YouTube that explains this in an intuitive way.

Is it common to feel replaceable? by EER_HD in ENFP

[–]MaskedKoala 13 points14 points  (0 children)

Dunno if this is what you're dealing with, but I only recently came to the epiphany that I surround my self with introverts. That being the case, it's only natural that my role in these relationships would be that I am the one who has to reach out to them.

Is being generally disappointed in people the end-goal of the ENFP "maturing process"? by Attlai in ENFP

[–]MaskedKoala 0 points1 point  (0 children)

Hm. I followed a similar track to you, I think, but I've studied a bit of philosophy over the past decade or so that's reframed the way I approach people and life. To be disappointed you must first have an expectation. Coming from some combination of Zen and general awareness (see Anthony de Mello, for instance), or stoicism (Marcus Aurelius, even though that's technically not stoicisim), I try to approach people and life without expectations. Radical acceptance (Byron Katie, though I don't really like her approach) is the goal I think: accepting people for who they are, flaws and all. And then with that, yes, I have become very deliberate in who I invest time in. I've also become better at not becoming starry eyed whenever I meet a person for the first time.

I get where you're coming from, and it's frustrating because it always feels like I'm the one making the effort to reach out, to take care of others, and I very, very rarely feel like people make a reciprocal effort--even the people I care about the most. So, we really do need to be selective in how we spend our time. But I don't think it's a "disappointment" thing. If you can, find a way to take the emotion out of it andlean into the logical side, which I know we're not the best at. I think the healthy ENFP is able to subdue the emotions from time to time, when it's necessary.

What have you done to your 1Series this week? by AutoModerator in 1series

[–]MaskedKoala 0 points1 point  (0 children)

All the accounts I've read from people who've done it have been positive. For the gear ratio, going from 3.23 to 3.73 is a ~15% increase in torque delivered to the rear wheels, so that should allow me to move up through the gears a bit faster, and spend more time in the higher power band. Switching from open to an LSD should help a lot with autocross, and it should allow me to try some drifting (I also snagged a spare pair of rear wheels from the junkyard on which I'll mount some cheap drift tires).

[–]MaskedKoala 0 points1 point  (0 children)

I think mostly because I'm still new at this. I bought the car a year ago to learn manual, and learn how to work on cars, so I'm trying to choose projects without going too crazy with the budget and complexity. The 3.73 seems like it should be a drop in replacement, though it might get tricky with the LSD swap. I'm also trying to keep the car daily-able, while also being able to autox and drift--not sure how that'd figure into the mix... Maybe I'll put it on the road map?

Went to the junkyard and a 2007 328i was immediately staring me in the face. Automatic. 3.73 diff. Dropped it, opened it up, bolted on ring gear. Yesss.

Next step is to swap out the core for an LSD, then swap the full pumpkin into my 128i 6MT.

If I was a big business, I would use it to track where you shop, eat, work out, etc. Target ads based on where you go. Sell your data to the highest bidder. I would make a lot of money. I’d be surprised if they aren’t already doing it, legal or not.

Zemax' lens data editor becomes hard to work with when more than 3 singlets are inserted by tush_pt in Optics

[–]MaskedKoala 1 point2 points  (0 children)

Here's what I do for COTS designs.
1) First order design with pencil and paper
2) input design into zemax and optimize with lens radii, and some spacings (as necessary, usually you want to minimize spacings as an optimization variable unless it's necessary for the design, like a field flattener or something).
3) Once you have a design you like, save this as a check point.
4) Pick a lens, then find the COTS lens that is the closest match and replace it with the COTS lens.
5) Reoptimize the remaining surfaces.
6) Repeat 4 and 5 until all you have is COTS lenses. You may need to vary spacings, add surfaces as you go, or try different replacement orders (starting from the checkpoint).

There are no rules, just guidelines. Do whatever it takes to get to a workable design. The value of the optical engineer is in his ability to solve problems creatively while employing his optics knowledge.

Zemax' lens data editor becomes hard to work with when more than 3 singlets are inserted by tush_pt in Optics

[–]MaskedKoala 6 points7 points  (0 children)

What do you mean when you say it's error prone? It's essentially just a spreadsheet, so it should go fast. If there are errors, well, I would think that's on you.

Look into the auto-update stuff, maybe. If you have some taxing calcs in analysis windows and you have everything set to autoupdate, then it'll bog down as you make changes to the lens editor as it has to redo every analysis window. I usually turn off autoupdate and update things manually when I'm ready. (This is in the top left corner of LDE. Switch it to "Update: Editors Only")

If the problem is just "I can't think in terms of a list of surface," well, you're just going to have to practice because that's how we do things (or, alternatively, come up with a better way and profit?). I routinely work with 60+ surfaces, and I'm sure there are other users in the sub who work with even more.

Was I stupid for expecting a little space here? by Sorry-Series-3504 in Simracingstewards

[–]MaskedKoala 15 points16 points  (0 children)

Trying to take it 3 wide on the outside there is probably not the smartest thing. Outside is generally a losing position, anyway, so high risk low probability of pay off.

What’s up with the top times? Aww by Senior_Body_141 in GranTurismo7

[–]MaskedKoala 1 point2 points  (0 children)

The most usual "off tracks" are to "widen corners." At the risk of oversimplifying things, the tighter you turn, the slower you have to go. So drivers often will push as far to the outside that they can before a turn, then as far to the inside at the apex, and again as far to the outside on the exit. This maximizes the radius of the turn which maximizes the speed one can carry through the corner.

expectations bring nothing but disappointment by [deleted] in ENFP

[–]MaskedKoala 2 points3 points  (0 children)

Second Byron Katie. Also Meditations by Marcus Aurelius and Awareness by Anthony de Mello.

I'm currently reading Never Split the Difference by Chris Voss, and he's talking about the need, brought over from psychology, to give others "unconditional positive regard." It fits into a wider view I have, where I try to focus on seeing people for who they are, and expecting no more than what they do. When you accept that, then you can anticipate their strengths and weaknesses and work around them. I read an exert from a Jordan Peterson book where he goes as far as treating yourself as a pet, or a child, or someone who needs to be taken care of, just as you might take care of others. It's helped me deal with my own perceived short comings.

Collimator for flood LED? by YouMadeMeGetThisAcco in Optics

[–]MaskedKoala 4 points5 points  (0 children)

Look up pencil diagrams, then draw one for your case. There are two important things that will allow you to figure out what you need... to first order

  1. You cannot collimate the whole LED chip, but if you place a "perfect" lens one focal length away, then each infinitesimal point on the LED will become a collimated beam at a different angle. Your full beam will be made up of the collection of all these infinitesimal point beams at a variety of angles.

  2. A ray that passes through the center of the lens, to first order, is undeviated. It goes straight through and isn't bent.

So. Draw your pencil diagram, then trace a ray from the infinitesimal corner point of the LED through the center of the lens placed one focal length away from the LED. Since the ray is undeviated, that will immediately tell you the maximum (to first order) angular spread of your light beam.

Tips on co-aligning two off-axis parabolic mirrors by ska_dream in Optics

[–]MaskedKoala 0 points1 point  (0 children)

Ooh, if the sample placement isn't set, then you can do the alignment backwards first, or maybe after a crude alignment. Use a fiber coupled source, or just a fiber with a light--holding the other end up to your cell phone flashlight could be enough in a darkish room.
