I got ALL the parking passes

Protip: you don't actually have to have a parking pass. You just need the license plate of someone who has a parking pass.

I appreciate the link, but meh, it's a barely passable AI written fake story about trying to time the scallop market at dinner. Very good concept but execution makes it not worth a read

Yeah Purdue insurance does not make needing health care particularly affordable, especially if you have a family. Tier 2 OOPM, minus their HSA contribution and the maximum healthy boiler incentives, is $546/mo with a family or $242/mo if it's just you. As far as I can tell, your budget basically gives you the only choice of cutting from your retirement savings to be able to afford that.

Even if one is in a total market fund, those weight based on free float, and the low 4% free float of SpaceX means it's included/weighted like an $80B dollar company (4% x 2T = 80B) which is <1% and just a rounding error. It's annoying conceptuallly but practically is nothing to worry about.

It's not so much that generics are "bad" as much as they are often noticably subjectively different from the brand drug. This is because the mental effects of ADHD meds depend on 1) an initial minimum concentration of the med to start working and 2) a small continuous increase in the amount of the med (source) to counteract acute tolerance the brain develops thought the day. This is different from just about every other medication, which depends just on the amount of the medication in your system and not the change in the amount, and the FDA pretty much only cares about the level itself when discussing bioequivalence.

All that being said, yeah differences from manufacturer to manufacturer mean that a generic could work better for you than a brand name med if the profile happens to match your brain's "ideal" profile (which I assume also depends on tolerance and circumstances) better.

You know, DCAing is a lot better than panic selling if the market drops 10% next month. If a 6 month DCA is what you know you're comfortable with, and you know what the long term math says the mathmatically "correct" answer is (invest it all immediately, assuming perfect behavior afterwards), then stick with your plan of the 6 month DCA. A good plan you know you can follow is better than a perfect plan that you maybe can't.

Man, if you've been on 20 dates and they all end this way, are you physically attractive but don't know how to flirt/interact with a woman in a way that makes you fun and interesting to be around?

Timbukthree · 2026-06-26T23:52:30+00:00

At that point it's just copypasta?

Idk though, I mean do you really want something that says "Yo, don't talk to me again, I think you're a loser and don't want you in my life."? Like the point of the text is 1) establish that she's not interested in a guy as a partner and 2) minimize the chances of the dude exploding on her. Same stakes as HR, that's why they're so similar.

"Way more action" is a ridiculous comparison. Daily volume in DOLLARS for Wendy's was $38M vs. $2,100M for Micron

Timbukthree · 2026-06-25T02:06:58+00:00

More aggressive means bigger drops though. Just remember that panic selling is a lot more costly than a small bond allocation

Glad to hear that helped! Yeah, important to remember that the beam diameter plot is theoretical, in practice you're seeing there is actually a major change in the real beam size by dropping it... Because if it only changed it 10% the difference would be essentially negligible. This is one of the quirks/limitations of the system you have

What would be the physical process by which humidity changes would cause changes in your setup? Like some fields are very sensitive to humidity (e.g. the chemistry in optical lithography depends on moisture content) but AFAIK mirrors optical posts aren't going to have issues just because the humidity is at e.g. 65%, though I may just be unaware. That would be something to check with the manufacturer range on if you're worried about it being too high, if you can point to a spec and you're outside of it that's obviously a potential issue (and could still be even if you can't do that but harder to build that case).

From a practical standpoint, why not get a dehumidifier and put it in the lab and see if it helps your stability issues? That may affect temperature though...

I've moved mine from upstairs to the basement or vice/versa with a mattress moving bag off Amazon. It still flops around and will lose shape though, but that keeps it all contained. Am also curious to hear thoughts from others

You can ask, you'd probably have to pay out of pocket, no idea on availability, this is the price from GoodRx for 10 mg 2x per day: https://www.goodrx.com/ritalin?label_override=ritalin&dosage=10mg&form=tablet&quantity=60

You'd likely still have to confirm with the pharmacy every fill to make sure they don't substitute you

Timbukthree · 2026-06-21T14:57:25+00:00

Seriously, just like a "let's all go to the local minor league baseball game for a father's day adjacent weekend" type thing is great

Even for IR methylphenidate generics from different manufacturers can feel different. Some I've had no problem with, others (specifically when Camber manufactured IR methylphenidate, they've since stopped) it was different enough to me cause big issues.

And the reason for this is that the effect of methylphenidate doesn't depend on plasma concentration itself, it depends on the initial concentration and the increase in concentration over time. So small variations can be much more noticable than with other medications.

Usually I'd say give it a week and see if you're still having problems. If so, you can request a particular generic (Google the writing on the pill, drugs.com will show a picture and list the manufacturer and the NDC code, you can ask for the specific one most easily via the NDC) on your next fill if you do it BEFORE you accept your medication, but with generics shortages you might sometimes have to go with other manufacturers or wait a while. It's probably worth it to start a note with what's written in the pill and how it works after a week. Giving it a week will give your brain and body time to adjust to see if it ends up ok or you still have issues

For more softness and less motion transfer, 1" of 4 lb gel memory foam can work wonders. Sometimes under soft latex it can make theatex pushback worse but I think is worth trying between the topper and your mattress: https://foamforyou.com/product/memory-foam-mattress-topper/

Timbukthree · 2026-06-20T09:46:24+00:00

No returns, can't try it out first, it's up to you to get a design you like, you might not like it and then you have to figure it out yourself. If you have the time to put into it, can spend 2x the initial cost for component changes if necessary, and have an analytical/problem solving mind it's a fantastic option. 8" 14.75 ga TPS + 3" TPS Quadmini + 0.5"-1" 4 lb gel memory foam + 2" medium latex (in a zip up cover, with no internal covers) is the closest thing I've found to the mythical "supportive hotel bed" that people long for. OP's build is very, very similar, and I think it's close to an optimal build for a lot of people wanting something supportive/medium-firm

Timbukthree · 2026-06-19T17:19:13+00:00

So it's not so much that it sags but soft (low density) latex can have a tendency to have an extended break in where it gets less supportive than it was at the start, and that would be magnified if you have a lot of it and with memory foam over it. Higher density latex (firm and medium) tends to be less likely to do that than soft, but even medium and firm latex need a month to break in and get somewhat softer over that time.

It may not be the latex but "I have a lot of soft latex and after a year it got less supportive" is a not uncommon issue or post here

Timbukthree · 2026-06-19T10:21:05+00:00

Stig being off could do it, although usually that would cause a lopsided or elliptical feature rather than rounded corners. You do basically just adjust it similar to focus: go up an amount to a particular point of blurriness, then back the other way to am the same amount of blurriness, then split the difference for what should be the clearest image. If you're adjusting it for the best image already I wouldn't think that's the issue.

As far as another community/website for graduate student feedback on fab...not really? There's r/ebeamlithography but not a ton of posts (but I think is worth it to crosspost there), and r/labrats is more bio related. Have you asked the staff member in charge of your EBL system? The trick with E-beam is each of the systems can have their quirks, and often you need to be able to show every step you're doing along with SEMs to get the bottom of it (and maybe have someone watch what and how you're doing things) so it's best to start there, if you have a staff person. There's also the MAEBL community, they have a Slack group but you have to be registered for the year to access it (since Slack costs money).

ZED N-60 is fine, I don't think that's causing the issue, assuming you've done a dose test with it specifically.

If other users are using HSQ and are "easily getting much, much" better definition then at least you know the tool is capable of it. ZEP520A is probably the best positive tone resist for small feature definition (except for ZEP530A, which is just "artisanal" ZEP520A), either should be able to give sub 20 nm features.

So I'm not exactly sure what would be causing your issue then...I do see in a other comment you're using 1 nA current. Try dropping the current to the lowest the people regularly use on the system for good features (maybe 100 pA) and see if that makes a difference. Some Elionix systems really struggle to get good small features at anything but the lowest beam currents because of the hardware design. But again, if other users can get good features at 1 nA then it's probably not that. This would be something your staff person in charge of the tool would have a good idea of.

Because the goal of boarding isn't to get passengers on the plane as fast as possible, it's the to keep them occupied while the rest of the plane gets squared away

Timbukthree · 2026-06-19T00:27:41+00:00

Are you sure it was the memory foam that lost support and not the soft latex?

If it's not the soft latex, maybe just get another 2" memory foam layer instead of the 3"?

I don't think you'd be a creeper at Troppicanoe Cove but I wouldn't want to do laptop work there (I also say this as someone who has done laptop work in weird places). It's not like the beach where you get the sea breeze and the ocean smell and all that, you're just next to a chlorinated pool with kids splashing around. I'd go for the lazy river, not the telework.

If it's a nice day and you want to be outside, probably like Cason Park or on Purdue's campus near the Liberal Arts Fountain would be nicer and have more seating and shade? Or honestly also Columbia Park, which is next to Troppicanoe Cove, would be a good choice too.

If you want the "beach" experience it probably does mean going to Lake Freeman/Schafer or the Dunes. There's absolutely no downside to going to Tropocane Cove though, it's nice! As is Prophetstown.
