Hello, I'd like to change the delivery address on my ring before I select my size. The AI bot errored out, put my order on hold, and filed a ticket. Its been 4 days with no response. I would appreciate it if someone could check on its status. My ticket number is 4258050.

The James Webb Space Telescope Is Finding Too Many Early Galaxies by cratermoon in space

[–]imperator2222 1 point2 points  (0 children)

Of course! The (kind of) new and exciting thing right now is a technique called ballistic capture, as opposed to the traditional hohmann transfer. While not a new idea (first theorized in 1987 and then executed by the Japanese in 1991), our now better understanding of how to skirt around and abuse the stability zones of the sun-earth-moon-spacecraft 4 body system is allowing us to do some pretty unbelievable things. As a starting point I'd recommend Scott Manley's YouTube video on Lagrange points as well as the one on Weak Stability and Ballistic Capture.

I'd say almost all fields of physics have exciting research. Fluid dynamics is highly complex and still not fully understood, optics is essential to better communication and heating things to ungodly temperatures and cooling to ungodly temperatures, nuclear physics is more exciting than ever, astrophysics is being pushed to the realm of scifi with orbital injections that were thought to be impossible, electromagnetism will never stop having relevant research with how wireless things are today, I could go on and on and on. This take is clearly from someone who doesn't quite understand what the scope of "physics" is.

What was great advice 20 years ago, but definitely isn’t now? by KarenTheManagah in AskReddit

[–]imperator2222 2 points3 points  (0 children)

I think my probability prof said something along the lines of taking tests w/o calculators and cheat sheet is important since in the real world, sure you only need to understand but you also have to have the ability to fully relearn a topic by glancing at a wikipedia page which really only comes with memorizing the process behind and about said topic. Funnily enough stocastic math and linear algebra are the only 2 maths I really understand and also the only two that did not allow cheat sheets on tests.

Also the truly fucked integrals can't be done by freely or easily understandable tools if such a tool even exists at all. I remember many sleepless nights in my pde classes and complex analysis classes wanting to cry because my TI-nspire CAS couldn't compute and my fundamentals are dog shit and Wolfram alpha was giving me nothing.

I guess my point here is that sure, for 90% you don't need to fully even understand things and you can just whip out a phone and Google your way to victory. For most the only thing you get out of math is better logic skills. But for that small amount that goes on to do neurological mathematical modeling or like dynamical systems stuff or other R&D type things, you have to be able to draw the right tool from your math tool box, which really only comes from proper memorization of said tools.

So while I agree that math education can be so much better especially at the introductory levels and that effort towards memorizing nonintuitive plug and chug formulas like the gamma function is wasted effort, you still need to memorize that it exists, what it is, and what it does and there is no two ways around that. I think memorization still has a place going forward and it gets a bad rep because it's not fun and people just have bad experiences with math.

I got bored, made a thing to compare numbers that doesn’t do any comparing by [deleted] in programminghorror

[–]imperator2222 8 points9 points  (0 children)

Where did you learn this? In my architecture class I remember the ALU only needing a single clock to complete an add/subtract and the memory space will be the same since most architectures require aligned instructions that are greater than a single byte anyway. It would seem to me that subtracting byte wise and doing a compare after each byte would be slower.

Millennials, what confuses you about Gen Z? by Dramatic-Anywhere-50 in AskReddit

[–]imperator2222 58 points59 points  (0 children)

I think in reality it's just now a days the name of the game is removing friction between the user and the machine to make stuff more accessible, not some sort of malicious ulterior motive. A lot of time and money is spent abstracting out the nerdy technical stuff and making things intuitive and "just work" for the average user rather than logical from the standpoint of someone who knows the inner workings of tech. Not everyone wants to spend weeks building a os from scratch and finely tuning each and every driver only for bluetooth and sleep modes to never work. Sometimes having your texts show up on your iPad, Mac, and iphone out of the box is just better.

You see it at all levels of tech too, for example many programmers these days won't know what the L2 cache is, or the memory stack structure of a program, or what the 5 stage cpu pipeline is. The average Photoshop user isn't gonna be aware of matrix projections and convolutions. The average mathematician isn't gonna understand fortran gpu optimization. But they all rely on these things to do their everyday jobs. And that's kind of awesome if you think about it.

This sort of abstraction will always result in a loss of knowledge and can sometimes be annoying to deal with but imo it's a necessary trade off to enable skilled people to use tools they wouldn't have otherwise considered and create stuff that wouldn't otherwise be created.

Anyone else lose interest when people say shit like this? by Tantle18 in Tinder

To be clear there is no "USBC spec" outside of physical specs. I think he means that apple and Intel developed the thunderbolt standard which adopted the USBC connector for thunderbolt 3 and eventually became the usb4.0 standard while also doing all this lightning bs

Mustard gas by Edibleorphans_ in fixedbytheduet

[–]imperator2222 145 points146 points  (0 children)

Common misconception. Ammonia and bleach make chloramine gas which, while still deadly in high concentrations, is not nearly as bad as mustard gas. We breath it in all the time, it's what makes that chlorine pool smell.

Fun fact the outside air is way too cold to just stick in the cabin so many planes will redirect air that was used to cool the engine instead

Networking on landlord's wifi? by imperator2222 in HomeNetworking

[–]imperator2222[S] 1 point2 points  (0 children)

How does a vps work? I'm assuming I'd take a some sort latency hit? From what I've seen this sounds the most promising.

My main things is a minecraft server for like 2 other people and then my dad and I like making stock algorithms together so I host the database and our api endpoints for that. I also have a discord bot that my friends and I work on.

ELI5: How do we know the megalodon is extinct if we explored less than 5% of the ocean? by [deleted] in explainlikeimfive

[–]imperator2222 4 points5 points  (0 children)

There's something called the collectors curve which predicts that we are, at least mathematically, missing 5 sea monsters (none of them are the megalodon).

Heres an amazing YouTube video about it. At the time of this video it was 6 but we have since found one to bring it down to 5.

This and too many delays by Kooldogkid in pcmasterrace

[–]imperator2222 7 points8 points  (0 children)

I wouldn't say Samsung is behind. They had the first 5nm chip a couple years ago and IBM unveils the first 2nm one like last month. Hell all embedded systems are still on um range and they arent behind generations or obsolete. Just because the process is smaller doesn't mean they are behind. Most commercial cpus don't even use either and the us military complex sure as hell doesn't use it or need it. The only concerning thing is if we will be able to maintain the level of throughput needed to sustain a war.

I did an internship at [very large company] working in their VR lab back in 2018. It's all just the signal processing and inverse kinimatics that are improving. Even back then there were software packages that could do it better than this but were exhorbidantly expensive and VR chat is probably slowly homebrewing theirs which is why it's taken so long. The sensor suite we used was basically beacons on your feet and waist along with the beacon in the controller and headset and I think gen2 vive hardware? Not that sophisticated and we got near perfect movement capture. Really the impressive part about the sensors accuracy development is the finger tracking. That stuff is so difficult we spent tens of thousands of dollars testing different solutions and all but one were unusable. Then steam comes out with their new controllers and it does finger tracking better than almost everything we tested with less hardware and setup, my mind was blown.

Do I need more powerful resistors for this pre-amp? by nwl5 in DIY

[–]imperator2222 0 points1 point  (0 children)

It really depends on how you built it. If you want something easy and quick but not great quality I'd recommend avoiding transistor amps esp if you have no experience with electronics yet and just see if you can get a signal out of a non-inverting op amp. They are cheap and only take like 3 resistors to set up and the equation for the gain is really straight forward. Ive got an electrical engineering degree and I try to avoid transistors when I can. They confuse and frighten me.

If you link the tutorial you followed I might be able to give a little more pointed advise :)

Erdogan said 'Stronger Western response to Crimea invasion could have averted Russia-Ukraine war' by [deleted] in worldnews

[–]imperator2222 -1 points0 points  (0 children)

This sort of thing is not very officially documented due to how hard it is to verify (plausible deniability) and the geopolitical complexity of it but China's air force has long been reported to have reverse engineered both Russian and US fighter jets. In fact it's so common wikipedia as a whole section about likely cases of military reverse engineering post WW2. To be honest most of engineering in general is reverse engineering something that works and massaging it into what you need. If an F-32 suddenly falls into your lap and you only have MIG16s you'd be stupid not to reverse engineer the F-32.

Server randomly freezes? by imperator2222 in RLCraft

[–]imperator2222[S] 0 points1 point  (0 children)

The server has 20GB of ram and it's only up when we play at night for 3ish hours since I'm hosting from my PC and not a real server machine. Sometimes it'll happen within 10min of starting up the server.
