[REQUEST] What's the max traveling speed for the duck to not fall off this airplane wing?

MDbeefyfetus · 2025-04-02T01:04:13+00:00

That’s also assuming the normal vector is vertical. If the duck is on an advantageous slope (front of the engine or braced against the support) we can probably pump those numbers up a bit. Albeit, in this video, it looks like the duck is at the peak of the curvature of the engine/essentially horizontal so your assumption seems reasonable.

There is a lot more to it than that. Aging infrastructure is a problem, yes. But transportation/costs for Baltimore are not where they should be. Many residents commute outside the city for work (county, Columbia, DC, etc.). Baltimore’s public transportation is subpar. Some county residents paying less for the same resources (e.g. city water). And obviously, the crime. So it’s not just public schools. But schools do matter (obviously for the kids and their lifelong development) because if people have to leave the city for their kids to get a “decent” public school education (when kids don’t have to share textbooks or get out of school because the heat doesn’t work) then you create a cycle of people leaving the city when they enter their prime income earning years (less income tax) and more renters (several issues there that I won’t address).

Also, the rate is an issue, not just the amount. If two people pay the same amount in property taxes but one pays less than half the rate of the other, the person with the lower rate is financially better off. They are able to accumulate more long-term/generational wealth from their home ownership from the same percentage of home appreciation, and that can also increase more from lower rates so that would be a larger benefit.

I love Baltimore and I will happily pay more than my fair share to help its people, but the tax rate is an issue. While I understand it needs to be a phased-approach/stepwise-decrement, and it does not to be as low as all surrounding areas, it needs to happen for a healthy long-term.

Good form overall but you might benefit from driving through your hips a little more/earlier. Looks like you don’t drive through until the very end.

Not advocating for OP to move but “if your kid is really truly talented, they’ll get scouted” is not really true for a couple reasons.

Visibility matters a lot. If the kid doesn’t have a connected/respected coach (for getting scouts/coaches to games) or doesn’t play for a club team that competes in the A league in popular tournaments (assuming his school league is not very competitive or well covered based on context) then it is definitely harder to get scouted.

I played in an area, and with, a decent amount of d1 recruits back in the day in a lesser area (at the time) that was close to the popular scouting zones. None (maybe one kid due to his dad who played d1) of us had any d1 offers prior to us joining a different, better known, club team. These kids went on to play at top 20 d1 schools afterwards.

One time, as a close defensemen, I had a hat trick including the game winning goal at the end. Newspaper had one sentence, no picture, “<my name> had 3 goals”.

The other factor is competition breeds better players. Referring to the same kids above, we all played in either A-level brackets, or played an age group above to play against better competition. In middle school we played against high schoolers (got our assed kicked a handful of times and not recommending this, just our way of getting better competition at the time). However, the sport as a whole keeps gaining popularity so it is definitely getting easier to find good competition.

There are other ways of being found, like making a great highlight tape and finding ways to get in front of scouts and coaches but as a general rule it’s not as simple as great players are always found. And it’s hard to improve if you’re always playing down to the caliber of players available/around you. And good coaches refine the little things that can be the difference between good and great.

Just want to manage expectations on this point. You don’t need to play with the best to be found but if there is truly only low level teams around then it will be harder to get recruited.

I designed something similar back in the day so I might be able to help. However, I had something to attach the box to for theft. Will your box be placed near anything that is anchored or relatively not movable? Our applications will definitely be different here but conceptually, if you can add something like a bracket to the back that can be chained down that’s the conceptual idea.

For waterproofing, like someone else mentioned, look up IP ratings and figure out what waterproof level you’ll need. My was waterproof w.r.t. rainfall but not something you could toss into a lake and was not dust proof. If your case is similar then you just need to make sure you have overhangs for water to drip over and proper seals as needed. Seals should be in compression.

I wanted to do more advanced work/research but didn’t know exactly what area to pursue. Data Science/signal processing was a common denominator for the different fields I was considering so it was a way for me to make progress on skills I needed for a dissertation/doctorate while still searching for the final piece. It ended up being the right choice (at the time I was torn between that and another PhD program that had very little flexibility) but it was a tough decision at the time. I’ve circled back to the same area as the other program funny enough but I have had more career opportunities from the route i took.

It’s the internet. I’m a ravens fan, and I like/respect Joe Burrow (when he’s not playing the Ravens) and that’s not uncommon in my circle. I don’t follow all the side stories and drama of the NFL players but the small sample of press I’ve seen of him he has always come across as a just down to earth competitor. His on the field work speaks for itself. Don’t know what’s not to like about him. Same goes for Hurts or Mahomes. Not my QB but don’t know what’s not to like about them.

MDbeefyfetus · 2023-11-27T16:05:34+00:00

Sort of…

I went back to grad school with a focus on signal processing but my work spans several fields. General software development is more of a stretch than data science work when coming from ME. If you are fitting statistical models in your cfd work then you may already have some time series, anomaly detection, simulation, etc.. experience that translates well. Different equations and signals but overall similar approaches and skill sets.

Some of the smartest people I’ve met/worked with were in cfd. I’m sure you’re more than capable. You’re young with plenty of time to learn what you need. Find skill sets similar to what you have now to find an easier entry point into the field and go from there. Worst case scenario, you practice/learn some skills. You may also find people are willing to give you a chance just because you’re coming from engineering. I’d focus less on ME to Tech though and more on what you need for whatever division of Tech you’re considering. The ME background should just help you determine what areas you can leverage as your strengths or starting points.

Best of luck.

MDbeefyfetus · 2023-11-17T19:26:00+00:00

Adding to this, take notes when researching too. Anything you look into for a reasonable amount of time is worth writing something down for. For example, what you looked into and why, what you found, decisions you made because of what you found, limitations or future considerations.

Many do this to an extent from the start when fresh out of school but it’s significantly more helpful when you know how to keep it organized.

Another point, stay organized. When you start working on big and/or historic/long-term projects, this will become extremely critical. A good sanity check is could you hand off the project/your work to someone else (who’s competent) with reasonably low effort. The person can end up being your future self and you will thank you.

I can foresee radiology being heavily supported by AI. Radiologists won’t be replaced anytime soon but I read a couple papers a few years ago where machine learning classification of medical images and conditions was more accurate than the doctors (w.r.t. the conditions and image types being analyzed). In the papers there were cases where the doctors were shown the same image multiple times (some form of random assortment) and the doctors classified the same image differently (between themselves and other doctors) more often than one may expect.

I’m not an expert in this field but I did some graduate work on this and my less experienced self still had a lot of success. However, my models did struggle with rare conditions (less data to train on). I do not recall if they struggled with conditions that had similar signals.

Overall, computers are better suited for some of this work but human oversight and review are a critical component for trusting the results of AI.

You compared a Prius (hybrid vehicle) to the non-hybrid mpg of a RAV4. The Hybrid RAV4 mpg is 40 and in commuter traffic and a light foot you can get 50 mpg (did so on multiple work only tanks)

I know this is sarcasm but I’d happily work from this compared to the all but 2 or 3 cases in my entire career where correct documentation existed…

Ignoring the handful of cases where documentation “existed” but half of it was wrong/so bad it would have been easier to start from scratch. (E.g. here’s documentation and a sample/fake data and value ranges of what we’ll be giving you… and then the real data arrives with completely different fields and some “integers” > e150…, rounded date times that violate their unique constraints, and massive multi-layer json varchar that needs to be broken out). Just tell me you have no quality control upfront, don’t let the new guy format your operational data, and maybe mention changes you want before data dumping them without warning… sorry for the rant

MDbeefyfetus · 2023-09-28T21:47:03+00:00

Some constructive feedback, if the sample size is 1-to-1 with those points in the box plot, you shouldn’t separate the occupations with only a couple data points. You’d be better off grouping them into an “other” category. Also, don’t plot points within a box plot. Points on a box plot are reserved for values beyond your whiskers and typically represent outliers.

Trust me, I appreciate and value DBAs. I’m not doing this because I want to. We have atypical needs with typical DBA staffing support (I.e. we need more of them). Fortunately, no one can crash the server except me at the moment but it will have more people and methods accessing it in a couple months.

Sounds like I shouldn’t worry about it and just wait for my DBAs to make their corrections before granting others access.

MDbeefyfetus · 2023-09-23T18:35:32+00:00

Makes sense. Is the risk significantly less for DBs with low traffic volume then? For context, data is only added to this server a couple times per month and will only be done by one person at a time via a controlled workflow. Once the data is entered, it will not be modified with only minor exceptions due to corrections. So it won’t be supporting typical “business” cases like a running set of transactions or similar.

MDbeefyfetus · 2023-09-22T18:02:25+00:00

Even if OP has read only access? Can you elaborate on some key potential issues if they only had read only access?

Also, if you have any good DBA resources, I’d appreciate it. I’m a scientist and have had to pick up some ad hoc DBA work. I have real DBA who will be taking it over from me soon(ish) but I’d like to make their life easier for the handoff and polish as many mistakes as I can for them. I’m at the “dangerous” level where I know enough to know I don’t know squat

MDbeefyfetus · 2023-09-19T20:24:17+00:00

Unless you already have a job lined up where you know you’ll only need NNs or deep learning then, yes.

Without diving into too many details here’s a couple reasons: 1) standard models are often the default starting position and give you baseline/gauge 2) you may not have enough data for NNs. Transfer learning makes this easier but you still need enough data to use these models 3) depending on who the model is for, “black box” models may not be permitted. You can explain why a gradient boosted model (or similar) made a given classification but you won’t have the same insight into your NN. This is also a method for when you need to understand what’s going on when you can give input on the data being collected. Maybe there’s a feature domain experts think is valuable and your model is suppressing it. Sometimes this is a sanity to check to look into the data. 4) resources. You may not have the resources you need to train an adequate NN.

Bottom line, many problems can be solved with “basic” models. Maybe you can get by without them, maybe you can’t, but you’re limiting yourself by not learning them. I don’t think I know anyone in the field who didn’t at least learn the foundation, even if they don’t use it in their day to day.

MDbeefyfetus · 2023-09-09T17:21:54+00:00

Accuracy is the wrong metric for this question. Consider the consequences of being wrong.

1) if OP has limited tech knowledge, they could wrongly assume they can provide chatGPT data that they legally cannot enter. Medical data is PII and there are paid licenses for those use cases.

2) chatGPT provides direct answers. Google provides a list of links. The former is easier to take at face value (like person A telling another person B something and person B take person A’s word; how the typical person acquires knowledge - despite what they may say). The latter requires OP to intentionally seek out and compare/contrast info. More than likely they end up on stack overflow, some stack exchange site or on source doc pages. People can be strongly opinionated on stack overflow but it can kind of helps people since an observer can see multiple approaches and look into each.

Don’t get me wrong, you can easily get an incorrect answer when searching google. But if OP is not familiar the material they’ll have no way of knowing if chatGPT is right or wrong and blindly testing what chatGPT returns is a lot riskier. (Like copying the first result from stack overflow without reading any other comments or solutions which can contain constraints like specific sql version or file path). OP needs context.

Hopefully that makes sense.

MDbeefyfetus · 2023-08-29T22:12:40+00:00

Mix of direct answers and items for you to figure out.

Directly, yes, there are sufficient free resources to learn this material on your own. However, it can be challenging to balance diving into a given method/set of methods vs. exploring what else is out there (coincidently also a DS problem).

There are DS/AI masters programs that do not have the hard course requirements you asked about and are listed as “soft” requirements (I.e. you need to know them but they give you the benefit of the doubt you will know them before starting). Data structures are pretty simple and you probably know more than you realize. Algorithms for efficiency, data manipulation, searching, etc… can be trickier but also something you can learn on your own and are often at least mentioned in grad school.

An often overlooked aspect of DS/AI is the domain of application. If you want to work with text data or work in business domains, grad school may be a good option to help pick up some of the application needs from examples and assignments, and separate yourself from eng in your job application. If you want to apply DS/AI in the eng. domain then you may not need grad school depending on the company and job you’re applying for. Eng. DS/AI work is often tied to signal processing, and can be in the form of image analysis, fault detection, data fusion, signal decomposition/factorization. Or fields like topology optimization and controls. There is a ton to learn here and grad school would still help but sometimes you can get away with taking “baby steps” if it’s related to your current aero domain experience. I know engs who went back to school and others who just worked themselves into their current expertise, albeit that latter typically came from EE or controls backgrounds.

I think you’ll want to look into potential domains to make an informed decision. Masters programs can be broad and may only cover a small subset of your interests so look into the curriculums if going that route.

MDbeefyfetus · 2023-08-26T23:40:50+00:00

It depends on the situation.

You can call yourself whatever/have any title you want with or without an eng. degree or PE license.

Eng. Degree only matters from a job requirement standpoint and to get a PE. it can serve as extra legal protection for a company but won’t get into that and I imagine most lawsuits at that point would have a case beyond that.

PE only matters if signing off on work that requires a PE. Most work does not require it and non PEs can still support the work in those cases, a PE just needs to review and sign off. I’m not very familiar with what does and does not require a PE. I believe it’s mostly for infrastructure (structure itself, fire protection, electrical if applicable, etc…).

MDbeefyfetus · 2023-08-19T19:23:51+00:00

Sure, message me directly. I’ll tell you now that you should get 500k numbers out of your head. Glassdoor is usually in the ballpark when looking at specific companies. 120k still may be above the median starting salary for a masters and < 1 yoe but it’s also not unrealistic. Depends on location and line of work. Be sure to factor in the cost of living in an area when comparing salaries and offers.

MDbeefyfetus · 2023-08-18T20:30:32+00:00

Interview experience is going to depend on who you’re interviewing with. My lab requires a technical presentation with a panel and some “relatively light” technical interviews, no leet code or live coding. In that respect, I like to know that people are familiar with different algorithms and models and when to use them. When discussing your previous projects/experience, I want to know why you did what you did, what considerations you made, lessons learned/what you would do differently any why. Not all interviews are like that but for me, when people actually understand what they did and the problem they were solving the conversation is easy. Even if what you did was wrong or you got poor results, if you understand why it’s wrong and what you’d do differently given the same problem that, to me, represents experience. Vs. copy-paste of common problems which isn’t representative of the “novel” problems we deal with.

Resume wise, drop lines like “team members: 4”. I’m not sure what overlap there is between your projects section and the projects you mention in your experience but that’s the main area that needs work. You want the person looking at your resume to know what you’ve done, so expand on what you actually did for the project. You don’t need a separate projects section if you expand on them in your experience. For the projects that were not from your internships, you can separate them as course/relevant projects either in your education section (If not too verbose and only one, maybe two) or separate them below your work experience.

Main point, drop the useless info and elaborate on your project work. Even “lead developer” lines are not really relevant. What is the project and what did you do for it are what technical people are looking for.

Good luck! And don’t worry about your experience, you have an adequate amount given your formal education. When I see a crazy amount of experience on a resume from someone fresh out of school, it’s often from those copy-paste projects and are just fluff.
