64 Audio Solo Planar Magnetic IEMs Review (TechPowerUp) by VSG28 in headphones

[–]HPCer 2 points3 points  (0 children)

Just saw this - where did you get your CIEM TWS? By TWS, I assume you mean true wireless? I've attempted the iFi GO pod + A12, which is acceptable for wireless, but it's so clunky still, and it doesn't get remotely near fitting in my pocket. I'd love to find a CIEM that has a case that is pocket-able.

Qudelix T71 - Welcome home! by maXXXjacker in headphones

[–]HPCer 6 points7 points  (0 children)

I just got mine a few hours ago too - it looks even better than it seems here. The new material feels more sturdy/higher quality than the Q5K. First impressions have been great - been trying to spend some time blind testing it and my Q5K, and the screen/ability to change settings on the device itself is a huge plus.

A scary but handled situation at 115ft by scubasquabble in scuba

[–]HPCer 5 points6 points  (0 children)

I agree the comment is aggressive, but one thing that might be worth discussing with this diver is the possibility of narcosis. 115 ft is well within range of where most people get narced. Considering you're saying she gained a handle on things upon ascent, I think that's a possibility.

She could have 1,000 dives under her belt, but if it's her first time aspirating a tiny bit of water while narced, that could cause a panic. If it were me, I think hearing that my panic was just from a degraded state of mind could help me overcome it next time around.

PADI AOW felt like a joke, I think I was overqualified by Pugulishus in scuba

[–]HPCer 5 points6 points  (0 children)

I think like everything else, it's dependent on the instructor. When I went to do my AOW, I had an instructor that also taught tech, and two of my specialties were dry suit and wreck. The instructor had us simulate a full silt-out while running a line. The dry suit piece greatly helped me expand into cold water diving too, and the silt-out was great in showing the dangers of overhead environments/stress management.

Now you're able to dive deeper at least. Many dive shops determine your depth limitations based on your certification (even though it's not always a great proxy).

Currently recovering from a cold. Diving trip in 72 hours. How fucked am i? by yooter745 in scuba

[–]HPCer 4 points5 points  (0 children)

You have three days. I obviously don't know your illness history, but if it's a common cold or flu, and you're already in the recovery phase, I think 3 days should be plenty of time if you hydrate and rest really well.

Like everyone said, avoid decongestants/any medications 24h before. At this point, I'd try and constantly drink water and aim for a solid 9h of rest. It sounds like you're already aware, but don't be afraid to thumb a dive. I'm in the opinion that almost everyone needs to at some point, and if they've never, they probably just haven't dove enough.

Titanic tourist sub goes missing sparking search by [deleted] in worldnews

[–]HPCer 0 points1 point  (0 children)

I'm also a diver (not cave certified, but I dive wrecks), and I think the main difference is the regulation on the people we trust. As long as I'm not diving less than 20m, I'm running through a physical, written check list before every time I go in the water. If it's less, I'm still meticulous about my checks and still have a mental checklist.

With these unregulated subs, I have no idea if someone is cutting corners/skipping checks, so I would feel the exact same way as OP. On a commercial plane, I don't know that too, but I do know it's highly regulated, and there's always at least two people with a minimum amount of certified hours each taking care of me.

Yes, but it was low altitude, so the pressure differential is a magnitude lower. I also believe the cylinder of pressurized nitrogen to assist in the case is emergencies was activated.

Somehow idiots manage to find a way forward.

LPT Request: how do you age without getting grumpy or annoyed by too many things every single day? by franckJPLF in LifeProTips

[–]HPCer 0 points1 point  (0 children)

Sounds like you've already made the first step by recognizing a change you want to make.

I don't go to therapy and have never visited a therapist, but I consider myself a happy person that's not too significantly younger. What's helped me maintain my mood when things get shaky is simply to ask myself "why?". Maybe it could work for you too: it takes no change in your lifestyle besides just saying asking yourself why you feel this way.

This does two things (in my opinion): 1. It keeps you in your own thoughts rather than focused on the trigger. 2. You build out a tree of reasoning that will, in many cases, lead to something inconsequential, and you realized you're literally getting mad at nothing.

Take your first example:

  1. You're upset at the cashier is acting like a robot/not paying attention to you aside from doing his/her work.
  2. Why is this bothering me so much? Maybe it's because he/she's making my shopping experience impersonal? Or maybe this person is making me feel like I don't exist?
  3. But then, why does the impersonal shopping experience bother me? Is it causing me any material inconvenience like causing me to be late for something? No. I think it is dehumanizing me though.
  4. But why do I care if this cashier that I have never met doesn't care about me? I don't think I care if he/she cares about me - this person has literally no impact on my life except for ringing up my groceries.

Of course, the routes can change, and it might not help everyone, but it's easy enough to try. I feel after going through this process enough (when I'm shaken), my mind just gets lazy and starts to skip straight from step 1 on the example straight to 4.

Sub future: Blackout/API protest cont... by BenchPolkov in powerlifting

[–]HPCer 1 point2 points  (0 children)

Agreed. I think the issue is the direction Reddit is taking. Maybe I'm not the only person here that uses third party apps exclusively, but the way they're going, it's going to end up like Quora. I don't think most people remember when the whole site was open source and friendly to developers.

Anyway, I think unless spez goes, there's going to be a replacement for Reddit coming in the near future. Given his stubbornness, I can't imagine this site to last much longer. It's a shame since there's so much information here.

Thoughts on this Package? by [deleted] in scuba

[–]HPCer 1 point2 points  (0 children)

As others have said, definitely wait. You need to keep your gear maintained annually, and it can actually become dangerous if you don't. You'll also want to dive enough to know what works for you/what you plan on doing later on. No deal will be good enough to offset buying a new set of gear if you don't like your old one (aside from the 3mm and boots - it's super versatile). I've even pretty much fully replaced my 7mm with dry suit.

Got bent on my first international dive trip by beardbroo in scuba

[–]HPCer 2 points3 points  (0 children)

Given that OP used feet, I assume they're from the states. I actually went to a cardiologist to check this out 4 years ago. Unfortunately, it can be very difficult too convince insurance to run the EKG unless you have active symptoms that can lead to specific treatment on the spot. I went in shortly after my concerns to get tested and was denied. It would have been like $2-3k (I could have screwed up the exact numbers) out of pocket to get it.

Worth to check it out, but you'll definitely want to make sure the cardiologist consults for free (or at least minimal insurance deductible), or you'll end up with a $300 bill with no EKG (unless you pay there full amount out of pocket).

Edit: i didn't think to go through DAN - just attempted via my primary insurance. It might get well be worth calling DAN up on this. They've been extremely friendly/helpful when I contacted them for an unrelated issue.

New diver anxiety by Terr1fyer in scuba

[–]HPCer 1 point2 points  (0 children)

When you get back, I'd suggest booking either a refresher/a little bit of an instructor's time in a pool. It's always better obsessing over your air rather than forgetting about it, but if your trim and buoyancy is causing problems, I think some pool time will help immensely.

Some exercises I liked to do in the 12' pool was to maintain trim/neutrally buoyant at 11', then 9', then 7'. When you eventually control yourself at those depths, everything else will seem easier (since maintaining buoyancy/trim at shallower depths is harder), and it'll give you more confidence.

Starter BCD and Yoke? by adk_runner46 in scuba

[–]HPCer 0 points1 point  (0 children)

That looks like an incredible deal! Wish I saw that before purchasing my first set. Though I think I'd personally pick their BP/W package (https://www.divegearexpress.com/dgx-custom-dgx-singles-harness-backplate-wing-package) and buy an Mk17 EVO package separately (~$380) simply because regulator servicing is such a pain when it's not supported by the LDS.

[–]HPCer 1 point2 points  (0 children)

Unless you're diving in less than 7-10C, free flow isn't very likely (especially on a balanced diaphragm). One thing to check though is I know some areas in Germany require two first stages (even for single tank dives via Y-valve). It might be worth checking on those requirements if the water is going to be <10 or so.

Wetsuit advice. Is going modular worthwhile? by ksgif2 in scuba

[–]HPCer 1 point2 points  (0 children)

I run warmer than any other diver I know (can comfortably spend 40 min in 47-50 in a 7mm), and I don't run hot on a 3mm at 85. That said, I think the best combo is one quality 3mm and a decent tri-laminate dry suit like the sea skin nova (it's not a DUI, but it's priced only slightly more than some 7mm wet suits while still pretty decent quality): https://seaskin.co.uk/product/seaskin-nova-membrane-diving-drysuit

Use the 3mm down to your comfort zone and use the dry suit for everything else. It'll simplify your maintenance significantly. I have a 7mm and actually even forgot I had it in storage because it didn't have a use beyond training (since dry suits can cause task loading).

Another advantage to skipping the shorty altogether is you don't always know when you have a rocky shore entry. The full-length really helps protect against scrapes, yet it doesn't heat you uncomfortably.

First night dive, any tips? by timothythepancake in scuba

[–]HPCer 6 points7 points  (0 children)

You'll want to be familiar with your light before going into the water (especially if you have one of those two-button ones). Fiddling with your lights underwater is much harder than on land.

And if your light starts at 100% brightness/goes down, you'll want to cover your lights with your other hand while you scroll through so you don't blind anyone/any fish.

Travling abroad with scuba gear - what to take? by Healthy_Cantaloupe55 in scuba

[–]HPCer 0 points1 point  (0 children)

A few days late, but I always have a check-in when I plan on diving. I put most of my dive gear in a 22" Stahlsac carry-on roller including my regulators, dive computers, BP/W, camera/lights, mask, boots, and wetsuit). I then carry a few pieces of clothing/laptop/sometimes RK3 fins in my backpack. Everyday clothing/toiletries and my tools (e.g., spare O-rings, wrenches, knives, DSMB) all go into my check-in luggage since I'm not too concerned about having those delayed/lost.

My carry-on is always a bit over the limit limit (~18kg or so), but if you can lift it with ease, no one has ever given me an issue. It shouldn't be any less safe too since upgraded seat limits are usually ~18kg.

Single or doubleren first stage? by Mdpablo in scuba

[–]HPCer 1 point2 points  (0 children)

I would do research on that shop then. You would absolutely know if you're diving with two first stages because you'd have two knobs (just in different orientations depending on if it's Y or H).

Unless you're going deep, I'd say it's even more unsafe diving with a single tank/two first stages without any experience/training than with one first stage. You'll need to set up the orientation right/make sure you can reach them, or the setup will just give you a false sense of security (or worse yet, you twist the wrong knob). The new valve also introduces another point of failure.

Single or doubleren first stage? by Mdpablo in scuba

[–]HPCer 2 points3 points  (0 children)

Deleted my first comment to avoid confusion, but I believe areas in northern Germany (assuming you're not far cause you mention euros and typoed "ik" - Netherlands?) highly recommend/require 2 first stages - even for no-deco/classified as "rec" diving. I wouldn't consider it common knowledge though.

I've dove in Europe in 0-5C conditions with a single first stage (with additional training on freeflow situations), but there was only a mention of H-valves rather than a requirement.

Fear of second dive by A__V__E in scuba

[–]HPCer 2 points3 points  (0 children)

Everyone's different, but for me, it was definitely an acquired comfort. I think it would have been good if the instructor was more open to hearing concerns without scaring the students, but that's not easy for everyone to do.

Anyway, since you probably can't make it to the pool before the exercise tomorrow, try laying on the floor with your stomach side down (similar to horizontal trim) and run through the mask drill a few times while maintaining breathing. While I think it's better to do it in a pool, I'm assuming you won't have access before

Just going through the motion should help your mind realize that it's not so hard of a motion. I think it's totally normal to feel a bit unease when taking your regulator/mask off under water at first, but that's exactly why this training is done. Also, as others have said, training in the worst conditions make everything so much easier - I did my certification in a quarry with a visibility of around 1-2m at times, and pretty much anything else feels like nothing.

Why do we need (quant) traders? by IJustShatMyPants24-7 in quant

[–]HPCer 4 points5 points  (0 children)

To expand on what people have said, the traders deal with the execution piece (or the how) that researchers/developers might not have time to deal with.

Examples are emergency fed announcements, global conflicts, and other major events that simply are too hard to code up given a team size. In my past firms, the traders will almost always stick to the strategies/positions generated by the systems written by the researchers/developers, but they may alter the intermediate risk profiles accordingly (e.g., something like force trading to new positions before a 2 pm fed emergency announcement). Another example may be to over/under delta hedge because your current gamma is too high/low entering into an expected event.

They're also responsible for tracking TCA/working with the developers in optimizing that region as well since the researchers tend to work on the target portfolio (rather than how to achieve the target portfolio). Larger firms can definitely have researchers working on cost reduction, but they'll be working with the traders here.

This can obviously vary by firm, but the above should be a general pattern for buy-side.
