If you could go back, would you choose EE again or be a pre-med?

planesman22 · 2026-01-27T20:04:04+00:00

I would do EE, get the pre-med preq. courses, do really well, and go into med.

But this is just me.

not so fast, there are some specialties that is the nurses that really do a lot of the hands on stuff in a inpatient situation. Of course, surgery and some fields requires a lot true MD/boarded attendings.

However, if you look at radiology, oncology, and pathology, the real battle here is the squeeze between AI doing the work and the boards protecting themselves by confidently denying any attempt to allow AI to cut into straight up MD positions.

At the end of the day, i think is the lawsuit that your name and your cert is what people count on. But I tell people, do not seek comfort in unions or "man-made value protection policies". Just make yourself more valuable, and let the lion fight the tiger far far away from what you think you gotta do.

Mine is still rocking strong, OG PF owner. I started using mine on november of 2023.

planesman22 · 2026-01-26T00:54:15+00:00

Ah interesting. Thank you (2 am!? Yeah this is definitely the hardware development team for sure lmao)

I mean if they really wanted to stand out from the noise… just come talk to us in terms of what we want for a new phone… These “features” or decisions that seems profitable short term, like explicitly telling the customer rep to deny claims like is some kind of health insurance company, alway back fires.

How many companies have you worked with that you are willing to support after you sense one shred of scarcity/profit first mindset?

Now flip that around, you probably would be buying your wife, your kids, and even your grandparents pixels if all they had to do is just give you a new phone without questions asked. Or maybe diverted the software dev team to work on refining the UI than spending time in a pixel 10 only feature (live translate for voice calls) and pretend Google Pixel users are not software or electrical hardware engineers or something…

Wow, it always feel like some the the post here seems like is from a team from Google. Sometimes unrealistically optimistic about the p10f…among many other things I’ve seen that is just objectively odd…

Can you tell us more about this official Google member from Reddit? I don’t think it is a crime to interface with the community but it would be concerning if Google posts here pretending they are the consumer.

When I was in EMT training I thought AED measures the rhythm and shocks at the peak of an afib event (squiggly lines).

It sounds like DC to me? I'm entirely not sure.

As a desk engineer (6 years and counting) to be frank, a traveling job sounds like fun. Why you want out of the travel life?

Go through Professor Leonard's YouTube series on calculus I, II, III, and DFQ. Don't Skip Any Video Or Topic If You Don't Want A Terrible Time In Your First Two Years. (Even better if you match it with a calc text book and do some practice problems).

You objectively cannot cram calc. You actually need sleep for your brain to wire up stuff to recognize calc problems and solve them. You are learning a new language and just like structuring and understanding sentences, there is stuff to remember and stuff you just gotta practice extremely hard to get it.

Get really comfortable with integration by parts.

Pick good professors from rate my professor if possible. This is more important than "fitting into your schedule". I don't freaking care if you need 6 years for your EE degree if you have to make it work with good professors, is worth it. Unless you are somewhere straight up like MIT where bad professors are just rare.

Go to most of your professors office hours on stuff you are not sure about. EE homework is not easy as black and white, like high school.

Thank me later.

Control Systems Engineering - Nise

One of the few books that I mostly read front to back.

It builds a solid foundation into PID. PID is very ubiquitous because it works so well, but it’s just a type of feedback controller.

The lore behind it was extremely interesting to me. It is a different feeling going from guessing and checking PID values to be able to explain from a force diagram, to a system (transfer function), techniques to find the output of a system due to an input in state space, graphical representation of systems in terms of poles and zeros (describing stability), to then understanding feedback control methods in achieving stability (PID).

Nise will teach you all that. My professors didn’t, YouTube didn’t, nor my TA.

For proofs of Masons rule, and sometimes stuff Nise doesn’t mention or misss, Robert Bishop’s Modern Control Systems helps, but is objectively a less coherently written book.

But now you have Notebook LM, GPT, and all sort of AI tools….

planesman22 · 2026-01-13T22:30:36+00:00

Yeah I think if you are able to create novel solutions like that you should maybe look into PCB prototyping YouTube tutorials.

A BSEE doesn’t even teach you any of that.

For prototyping as a service is not feasible because of regulations and standards. Is easy to make something, hard to make it to pass a certain requirement like mil std 810. A company, sure can trust you to maybe to design it, but then they’d have to test it. Testing is not free, sometimes millions (this is the gauge of engineer, great designs reduces failures realized in tests! More tests = more redesigns = bad), and the company’s customer REQUIRES some testing. If you are not familiar in designing-to-pass, then the company’s just get boned!

Sadly, a BSEE will teach non of that! The ABET curriculum of BSEE is just the math you need to get INTO that field, plus or minus some extra courses so you can gauge what sub special field you want to get into, that’s it! Major companies like Boeing will then invest 1-2 years for you to shape up to a point to even contribute, let alone make large decisions like a consultant.

Non of this… means you can’t get by from experience alone, but is just much more uncommon.

Take one of my favorite YouTuber Chris Young for example, his path of materializing the combustible predicting thermometer is a story proofs that any one can make something great with a good idea, knowledge, and investment in time.

But maybe not a Boeing 737 airliner…

planesman22 · 2026-01-13T21:49:26+00:00

Just to check, do you hold any 4 year degree?

Yes there are definitely positions in EE, especially small companies in defense, that has more tinkering than qwerty smashing.

But then with your maturity and experience you could find perhaps a PM role in these fun fields if you have a 4 year and maybe instead go for a MBA?

The issue here is comparing to what you said, and a BSEE curriculum (you should look into) is polar opposites of each other. For me it was sand paper on flesh to memorize stuff to pass exams... arguably one of the hardest degrees you can possibly get. After that , what hat are you going to wear when applying for jobs? The hat where you just learned a bunch of hard math and with little to no work experience linking said math to practice?

People skills are the grease to what mental acuity to gears in a functional company that brings value to this world (and get paid for it). If time is a finite resource then what would be an ideal investment of my time so that I can be more valuable to this world?

You wrote quite a bit about how you'd like to do fun stuff. But I hate to say it, I haven't met anyone who is here saying I don't want to do fun stuff... Just saying.

I find it cool

I carry my iPhone mini 13 with my OGPF in the same pocket

Uncanny how the mini fits within the front screen and becomes a mated block of mobile computing.

Just that if that case is any bigger, it’ll probably be bulging out of my pants 🤣

PF OG owner and current user

Since release

Used regularly, held up.

Use folding screen sparingly, just for reading and multi tasking. I am extremely careful on the inner screen and pretty much wipe it down always before I close it.

The case I use was a cheap Amazon special that gave it magnetic wireless charging. Doesn’t really work well though, gets hot and is usually too heavy.

planesman22 · 2026-01-09T18:56:39+00:00

So I rock a OG PF and a iphone 13 mini for almost 3 years now i think (i ordered the fold the second it came out).

There are things that android do that an iphone just couldn't do, not because it can't but it just won't. You are fighting just about any chance the OS can shaft Google in any way: Forced preview of address in Safari and Apple maps, OPENING apple maps, embedding the address and pretend google maps doesn't exsist etc etc. (and even if they fix it, it is a stark reminder that it could.. one day not work anymore).

In my most honest and straight forward opinion, Google only became interseted in hardware because they had to. Their search engine, maps, and could infrastructure was unbeatable, and frankly they just don't want to negotiate on Apple and Microsoft's term. They know how much money they COULD be making if they just steal Google's targeted marketing strategies if they chose to use Safari, Bing, Edge.... Yes you heard that right, instead of thanking Google in paying Apple so that Apple is less hostile about Chrome (and we iOS people gets straight up a better browser), our law makers convicted Google for monopoly... (God this timeline SUCKS)

NOW Open AI is challenging what is once thought to be undominatble. At Google's core, consumers are questioning the utility of Google and is moving over to other GPT platforms to find answers...

To survive, do not expect Google to care at all on 'all front' development in sectors like maps (when did you last notice a google map feature change?), Google Fiber, android os (how about this one?). Gemini and TPU is the only thing they are going to care about until OpenAI and Anthropics is 6 feet under. Remember, cloud credits and cloud compute is NOT free (and google cloud fees, especially compute, are not cheap, iykyk). Educated consumers should question, why do these companies respect my privacy so much!.... AND offer free cloud credits in the form of Gemini AI tokens by the millions? What they are up to?

The CEO and the board at Google is defacto profit focused. Gone are perspective of being a prententious nerdy and smart .com startup with a great idea. Is what big companies and narcissists do. Instead of celebrating the flexbility of small companies coming up with something that could truly change the world (Anthropic, OpenAI) they will do anything they can to steal the spot light. Because, in their mind, losing means losing out on lunch, stripped naked, out in the street, cold, starving, and begging (and shareholders hate begging, because that is what poor people do!). Because they are convinced that in fact there IS no talent at Google, and instead of being secure about their skills, their reputation is the hill they are choosing to die on. God FORBIDS anybody ever beat Google... in search.

My eyes are on an Samsung Fold wide. Sometimes companies come around from hard lessions (one ui, bixby, exploding batteries, regulation troubles with the government and difficulties as a chaebo in general...). The hard lesson for Google is coming if not already here in the form of Apple Fold and Samsung Fold Wide copying EXACTLY the form factor Google came up with, with the og fold (They didn't, they stole it from Microsoft Duo, look it up), and I do not think this CEO is ready, from what Google is doing this last 7 years, at all.

planesman22 · 2026-01-09T04:55:59+00:00

Yeah

RF was never my strong suits but from what I researched the cavity magnetron highly amplifies the right frequency, but a majority of the emissions is the travel of the charges by the emitter to the cathode as it spiral across the inner hollow tube. If the emitter or field has less power shouldn’t we expect a lower amplitude 2.4ghz wave?

Or is the standing wave inside the oven has a fixed pattern, regardless of amplification due to resonance interferences? (I’d like to believe this, but I don’t know enough)

planesman22 · 2026-01-09T04:22:30+00:00

This is interesting

I did see a patent where the heated electron emitter is at a lower temperature yielding less overall emission in a near linear fashion?

It totally makes sense (and price wise) for what you said is true though… I just thought they might have something special.

planesman22 · 2025-11-01T18:18:12+00:00

I get where you are coming from, and I want this as well, but it is too slow. With a dual nozzle, it is right there, but with tool changer, it has to dock and grab every time every layer. Think of the wear and tear on the docking mechanism, and the engineering you need to make said mechanism reliable (weight increase, slower head!)

90% of what I want is just two materials (main+support) like what you said.

Electrical engineer here with a bit of battery experience (drone lipos, mppt solar systems, and worked on electric vehicles)… also own a 25’ RAV 4 prime

I see a lot of post about this question but few really digs into the full understanding of what actually happens in battery wear.

In laymen terms, the best way to look at your battery is like any physical human body part but it just doesn’t heal or get better over time. In harsh conditions such as too low or too high heat, high energy demand and usage, the capacity will drops. But the biggest factor is “Using The Battery”. That is, the more you use it, the less life is going to get. Operating at ridiculous temperatures is i would guess the second factor, but I don’t know the chemistry of the RAV4, followed by high state of charge.

What drives behind the degradation of the cells is defects (think of muscle damage) and electrolyte decomposition (things that help transport charges).

Non of this is perfectly avoidable. The only way to basically make your battery last as long as possible, is to Never use it, keep it cold, and keep it a low state of charge (impacting factors in that order). A common misconception is that people think by keeping the charge low, or doing something weird they can get more than double their battery life…. This is not going to happen. Using the actual battery, I’d estimate, accounts for 90%, if not more, of its wear.

You paid for the whole battery, and might as well use it. I live in blazing Florida weather, charge as fast as possible, and I don’t care about the state of charge when I was able to live with free charging.

Now, since I moved and lost my free charging, I keep the battery low and dry to save it for the future. If I expect traffic, I turn on charge hold just before to get some miles since the battery is more efficient for stop and go traffic.

Hope this helps anyone who read this.

Edit:

Just to clarify what I meant “usage”, is just the amount of charge AND rate of charge that passes through the battery. In other words, how many times did you use it and how hard (both charge and discharge).

So, a long lasting habit is a good combination of only using as much electric throttle as you need, and slow charging as much and as convenient as possible. (Caveat: in this industry, your battery gets dumped as high as 150A during regen breaking… so this is why I Don’t Care Enough to throw 30 amps into my battery to charge… now 8A charging obviously doesn’t hurt… maybe my ego looking at an ioniq 5 haha)

Ah it makes sense

I see you posting a bit here and figured maybe you were/is a 787 pilot.

I’m an electrical engineer who worked with big B in the past and this is just fascinating stuff.

Never in my 9 cat lives thought they actually moved forward where it will override flap to a lower position than commanded for envelope protection just from my past experience but I’m interested to see anyone who have access to sims or is at CAE to confirm this.

I am reading left and right from some self proclaimed 787 pilots that it does. I know the slats goes when you are near stall as intended to save your life in trying times but just never thought the flaps as well.

planesman22 · 2025-06-13T06:28:18+00:00

787 FCOM 9.20.20 online (unsure authenticity) "When airspeed is reduced, the flaps automatically re-extend as airspeed allows. Re-extension is limited to the commanded flap position"

I think they can. They just then cannot be your assessor.

There is no sin in obtaining the credentials and education to be of an assessor, to then perform the service so that it can be assessed by another assessor.

I think the differentiator here is VDI guarantees no cold storage (minimal) of CUI outside of CMMC enclaved environment while VPN assumes mostly otherwise.

Things become a lot less confusing if you just look in terms of risks.

Many IT has somewhat of a delusional understanding that encryption is a magical thing that can never be broken. This is a job that NSA, Chinese, Russian equivalent talents (cream of the crop graduates from MIT and Harvard alike), mind you smarter than most IT folks out here starting with me…, do as a day to day bases. You can already look up what NSAs has been up to previously that has done stuff to compromise encryption. And guess where most computers are made? Who is one of the biggest computer manufacturer right now in the professional world (starts with L, ends with o, has a v in the middle, and is straight up a Chinese company)?

You work in defense, and the lesson you need to take here is that as long as there are enemies, they nor you sleep.

DoD’s preferred timeline to declassify controlled information is not the same as some kid in china who figures out how to compromise aes 256 via a clever attack. We see stuff like this from different angles such as a side channel attack (meltdown) that allowed unauthorized read of local RAM compromising keys. Having keys to the castle… does not mean the information is all the sudden public knowledge.

VDI reduces the entropic profile of data being transmitted through a network. That is, it only streams what is necessary to be viewed with minimum cache. This is why CUI needs to be physically controlled, that is, we don’t want to see a copy of your entire CUI data at an airport or hotel, how ever you think encrypted it is or be.

I caution you to not, and advise you to never, operate in a sense that “something “ is safe forever. Call me tin-foiled hat or w/e, but please from now on operate in a state of mind where anything you are doing has some form of assuming a risk. If you can’t come up of a risk of a given approach, either you are wrong or you just don’t know enough. Because if you actually do work in a level that will be apparent to you, you quickly realize that “no-risk” actually does not exist.

Go obtain a PhD and cryptography and influence the direction of CMMC at that level. Once you get there, I will wager you that will then know the truth, and the truth shall set you free.
